Patent GB-2097491-A (GB)
Title: A friction clutch
IPC: F16D13/26
Filed: 1982-04-22
Abstract: A friction clutch is provided with a plurality of swivelling levers (8) positioned in longitudinal slots (7) of a hub (3), an axially displaceable link ring (26) for pressing the operating ends (12) of the levers (8) and at least one friction element (22) opposite a friction face of a portion to be coupled (4). An axially stationary (18) and an axially slidable thrust ring (17) press the friction element (22) radially outwards, said ring (17) being acted on by the working ends (15) of the levers (8). The hub (3) is coupled in axial direction slidably with one of the shafts (2) and the friction face of a portion to be coupled (4), usually a drum, is fitted with a stop shoulder (28). This prevents axial forces from the clutch being transmitted to the bearings of the members to be coupled. <IMAGE>

Abstract: A magnetic printing apparatus scans a magnetic recording medium with a recording head having m channels (m >/= 3) e.g. four channels A, B, C and D. A magnetic latent image having a first line scan density is recorded by arranging for the first, second,... and m-th channels of the recording head to form magnetic latent images on the (mn-m+1)-th line (n is a positive integer indicating the scan number of the recording head across the recording medium), the (mn-m+2)-th line,... and the (mn)-th line, respectively as shown in Fig 7; the loci of the subsequent channels being overlapped on parts of loci of the preceding channels. A magnetic latent image having a second line scan density is recorded by arranging for the first, second,... and m-th channels of the recording head to form magnetic latent images on the (mn)-th line, the (mn-1)- th line,... and (mn-m+1)-th line, respectively; the loci of the subsequent channels being overlapped on parts of loci of the preceding channels. For recording a magnetic latent image having the first line scan density, the track pitches of the first, second,... and m-th channels of the recording head satisfy the requirement of the following formula (1): E1 = (am+1) x P1 (1> wherein E1 stands for the track pitch, a is an optional integer, m stands for the channel number and P1 stands for the latent image scanning line pitch, and, for recording a magnetic latent image having the second line scan density, the track pitches satisfy the requirement of the following formula (2): E2 = (am-1) x P2 (2> wherein E2 stands for the track pitch, which is nearly equal to the track pitch E1, and P2 stands for the latent image scanning line pitch. <IMAGE>

Patent GB-2123522-A (GB)
Title: A Gas spring or strut
Inventor: GRABNER CHRISTIAN
IPC: F16F9/02
Filed: 1983-07-06
Abstract: A gas spring 1, in particular for engine bonnets and/or boot lids of motor vehicles, consists of a cylinder 2 filled with gas under pressure and a piston 4 which can be displaced within it and which is connected to a piston rod 3. In order to make possible a greater extension of the gas spring 1 which exceeds the normal operating path, provision is made for a covering tube 5, open at one end, to be placed over the cylinder 2 so as to be telescopically displaceable relative to it. The other end of the covering tube 5 may have an anchorage member 6 and a buffer 7 may be provided on the end of the cylinder 2 inside the tube 5. This arrangement enables the bonnet or boot lid to be opened 90 DEG  when necessary, although in normal use the spring moves it through 45 DEG . <IMAGE>

Title: Improvements in or relating to cooking apparatus
Inventor: HAWLEY ARTHUR DEREK
IPC: H05B3/74
Filed: 1984-01-05
Abstract: A hob has a surface plate (1) of a glass-ceramic material transparent to infrared radiation from heating units located beneath the plate (1). Each unit comprises at least one tungsten halide filament lamp (2) mounted above a reflector (3) which may be clad externally with thermal insulation. Disposed between the plate (1) and the lamp or lamps of each heating unit is a screen of optically transparent heat resistant material that is also transparent to infra-red radiation. The presence of the screen reduces the extent to which the plate (1) is heated by convection. A further reduction can be effected by directing a flow of cooling air over the screen. In some cases, the screen can be omitted and reliance placed solely on the cooling air flow. <IMAGE>
