H Engine
An H engine is a piston engine comprising two separate flat engines (complete with separate crankshafts), most often geared to a common output shaft. The name "H engine" is due to the engine blocks resembling a letter "H" when viewed from the front. The most successful "H" engine in this form was the Napier Dagger and its derivatives. The name was also applied to engines of the same basic layout, but rotated through 90 degrees—most famously the Napier Sabre series. A variation on the "H" theme were the Fairey Prince (H-16) & Fairey P.24 Monarch, where the two engines retained separate drives, driving Contra-rotating propellers through separate concentric shafts. Although successful, they only existed in prototype form. The H engine is a relatively rare layout, with its main use being in aircraft engines during the 1930s and 1940s. The 1966 Lotus 43 Formula One car used a BRM 16-cylinder H engine, and an 8-cylinder H engine was used for powerboat racing in the 1970s. Design ...

H4 (classification)
H4 is a para-cycling classification. The UCI recommends this be coded as MH4 or WH4. Definition Union Cycliste Internationale (UCI) defines H4 as: *Paraplegic with impairments corresponding to a complete lesion from Th11 or below * No lower limb function or limited function * Normal or almost normal trunk stability * Non-spinal cord injury, functional ability profile equivalent to sport class H4 (ex-H3) * Incomplete loss of lower limb function, functional ability profile equivalent to sport class H4 (ex-H3) or H5 (ex-H4), with other disabilities, which prevent the safe use of a conventional bicycle, tricycle or the Kneeling position in a handbike * Recumbent position in handbike (AP or ATP-bike) * Diplegia and athetosis/ataxia/dystonia (almost normal UE) Hemiplegic with spasticity a minimum of grade 3, lower limb more involved. The cycle This classification can use ATP3 knee-seat cycle that is forward leaning on a rigid frame. Classification history Cycling first became a Paraly ...

British NVC Community H4
__NOTOC__ NVC community H4 (''Ulex gallii - Agrostis curtisii'' heath) is one of the heath communities in the British National Vegetation Classification system. It is one of three communities which are considered transitional between the lowland dry heaths and the wetter communities classified in the NVC as mires. It is a relatively localised community. There are four subcommunities. Community composition The following constant species are found in this community: * Bristle Bent (''Agrostis curtisii'') * Heather (''Calluna vulgaris'') * Bell Heather (''Erica cinerea'') * Cross-leaved Heath (''Erica tetralix'') * Purple Moor-grass (''Molinia caerulea'') * Tormentil (''Potentilla erecta'') * Western Gorse (''Ulex gallii'') The following rare species are associated with the community: * Bristle Bent (''Agrostis curtisii'') * Soft-leaved Sedge (''Carex montana'') * Dorset Heath (''Erica ciliaris'') * Cornish Heath (''Erica vagans'') Distribution This community is confined to s ...

H-4 Visa
An H-4 visa is a United States visa issued to dependent family members of H-1B, H-1B1, H-2A, H-2B, and H-3 visa holders to allow them to travel to the United States to accompany or reunite with the principal visa holder. A dependent family member is a spouse or unmarried child under the age of 21. If a dependent of an H-1B, H-1B1, H-2A, H-2B, or H-3 worker is already in the United States, they can apply for H-4 immigration status by filing Form I-539 for change of status with United States Citizenship and Immigration Services (USCIS). Family members may alternatively be admitted in other non-immigrant categories for which they qualify, such as the F-1 category for children or spouses who will be students or the H-1B category for a spouse whose employer has also obtained approval of an H-1B visa petition to employ the spouse. An H-4 visa holder is admitted to the U.S. for the duration of the primary (H-1B, H-1B1, H-2A, H-2B, or H-3) immigration status. A noncitizen with H-4 im ...

GNR Class H4
The Great Northern Railway Class H4 (classified K3 by the LNER) was a class of 2-6-0 steam locomotive designed for mixed-traffic work. The type was a more powerful development of the earlier H3 ( LNER K2) class and was notable at the time, as the boilers were the largest fitted to any British locomotive to that date. After formation of the London and North Eastern Railway, the type became known as class K3 and was adopted as an LNER standard design. They got the nickname "Jazzers" after the rhythm of their exhaust beat and the unbalanced gyratory movement. Construction The first ten locomotives were built at the GNR's Doncaster Works in 1920, to the design of Nigel Gresley. Six further batches were built at Doncaster and Darlington Works, Armstrong Whitworth, Robert Stephenson and Company and the North British Locomotive Company. The last few of 193 examples were delivered in 1937. Use They were excellent mixed-traffic locomotives, although their large size restricted t ...

When submerged each propeller was driven by a Electro Dynamic Co. electric motor. They could reach on the surface and underwater. On the surface, the boats had a range of at and at submerged.Gardiner & Gray, p. 128 The boats were armed with four 18 inch (450 mm) torpedo tubes in the bow.
