Title: Binding sheets of paper or the like
Inventor: SMITH KENNETH MALCOLM
IPC: B42F9/00
Filed: 1984-08-15
Abstract: A pad 20 of paper sheets is bound along one edge so as to form a booklet by means of one or a series of rigid non-resilient channels 48 clenched onto the edge of the pad. The channel is provided with inwardly-directed projections 18 which compress the sheets without penetrating them and so hold them in place.

Patent GB-2187242-A (GB)
Title: Self-adjusting transmission having planetary gearing on orbital shaft
Inventor: STIDWORTHY FREDERICK MICHAEL
IPC: F16H3/74
Filed: 1987-02-20
Abstract: A transmission device comprises an input shaft (1) rotatable about a main axis (X-X) and an output shaft (2) rotatable about the same axis. An input gear (6) on the input shaft drives an input bevel gear (13) of a differential unit having a differential carrier (18) rotatable with a first axle (9) rotatably carried by a carrier body (8). The differential carrier presents two stub axles (16, 17) carrying idler bevel gears (14, 15) engaged with the input bevel gear and with an output bevel gear (21) which is engaged with a stationary gear (24) via a reference gear (23). An intermediate gear (25) rotatable with the first axle drives via an idler gear (26) one (28) of a pair of output planet gears (28, 29) which are rotatable together with a second axle (10) supported by the carrier body at a different radial spacing from axis (X-X) than the first axle. The other (29) of the planet gears engages an output gear (7) on the output shaft. The torque applied to the input shaft is transmitted to the output shaft with a value which is inversely proportional to the speed of the output shaft, the carrier body (8) being caused to rotate in the opposite direction to the input and output shafts.

A method of producing the elongate blank is also disclosed as well as a flexible channel-shaped strip structure incorporating a channel-shaped core made from the elongate blank.
Patent GB-2325297-A (GB)
Title: Reactive armour
Inventor: BUGIEL GEORG
IPC: F41H5/007
Filed: 1988-06-23
Abstract: A reactive armour protection has optimum effect against KE penetrators (28), and also against the projectile or the particle jet of a shape-charge projectile with the least possible amount of explosive used to reduce reaction stress of the protected object. For this, the object main armouring (11) is fitted, along with shock-decoupling spacing (10), easily exchangeable cells (12), which respectively have, enclosed into a high-strength sheet-metal housing (24), a fast-acting lamination (20) consisting of a very thin explosive layer (14) between two thin steel plates (13), a stratified brittle-body filling (15), e.g. glass covered by an explosive covering layer (17), detonation-sluggish relative to the fast-acting layer (14), under a tamping metal sheet (18). A detonation connection (25) between the upper, slow layer (17) and the lower, fast layer (14) is provided. Upon the penetration of a KE penetrator (28), initially the lower fast layer (14) and then via connection 25 the upper slow layer (17) is detonated, which causes fractures and thereby reduces the kinetic energy of the penetrator (28). Upon the impact of a slower shaped charge projectile, the upper explosive layer (17) is detonated immediately and via connection 25 also the lower layer (14) is detonated, which counteracts the entry of the projectile into the brittle-body filling (14). Upon stressing by the very much more rapid and energy-rich hollow-charge particle jet, both explosive layers (17, 14) are detonated almost simultaneously.

Patent GB-2208611-A (GB)
Title: Controllable microfilter
Inventor: STRACHAN SCOTT
IPC: B01D29/60
Filed: 1988-08-11
Abstract: The filter comprises two films (10, 12) of polyvinylidene fluoride (PVDF) in face-to-face relationship and formed in a central portion with aligned apertures (15) in the range 10 mu  - 30 mu . Each film (10, 12) has electrodes (16, 18) on each face on either side of the central portion (14). Application of differential voltages to the electrodes (16, 18) produces relative lateral movement of the central portions of the films (10, 12) in a manner to vary the effective pore size of the filter by moving the apertures (15) out of and into register. Apertures may be cleaned by applying alternating voltage to vibrate the films combined with reverse flow. A silicone oil lubricant between the films facilitates relative movement. <IMAGE>
Patent GB-2207785-A (GB)
Title: Wafer scale integrated circuit memory
Inventor: BRENT MICHAEL
IPC: G11C29/00
Filed: 1988-08-17
Abstract: A wafer-scale integrated circuit comprises a few hundred modules 10 which can be connected into a long chain by commands sent to the modules along a transmit path set up by way of module inputs XINN, XINE, XINS, XINW from neighbouring modules and outputs thereto XOUTN, XOUTE, XOUTS, XOUTW, only one of which is enabled by one of four selection signals SELN, SELE, SELS, SELW acting both on transmit path logic 20 and on receive path logic 21 in a return path. A RAM unit 23 can be enabled by WRITE to write a block of data sent to RID via the transmit path and can be enabled by READ to read a block of data to ROD for return along the return path. The provision of SELN, etc READ and WRITE is effected by configuration logic 22 which includes a shift register and is responsive to a command mode signal CMND, on a line which runs to all modules in parallel. If, when CMND is asserted the bit currently in the transmit path is logic 0, the module is not addressed. If the bit is 1, the module is addressed and the bit is latched as a token within the XMIT path logic 20. The configuration logic then clocks the 1 bit token along its shift register until CMND goes low again. The first six stages of the shift register provide SELN, SELE, SELS, SELW, READ and WRITE respectively and the position of the token when CMND goes low determines which command is generated. The shift register has further stages for providing a signal ACR to reset an address counter in the RAM unit 23 and for toggling RPON which controls the power supply to the RAM unit 23 via a transistor switch. <IMAGE>

Title: Sheet feed
Inventor: SUGIURA TOSHIAKI
IPC: B65H3/06
Filed: 1989-09-13
Abstract: In a sheet feeding device provided in a printer or a copy machine employing a stack of sheets 14 urged upwards by a spring, the sheet holding lugs 30 are depressed by rollers 46 so that the sheets are brought out of contact with a pair of feeding rollers (18 Figure 1 not shown) while the stack is attached to or detached from the machine. Thus, the top sheet touches the feed rollers only when the case is in the machine, to prevent buckling etc. 
<??>Further, the spacing of the pair of feed rollers 50 (Figure 60) is varied in accordance with a width of the sheets. The rollers are urged against action of spring 58 by a system of bell cranks 62, 72, moved by a cam slope 80 attached to the cassette 16. The height of the slope is proportional to the sheet width. Thus the feed operations are executed without feed errors, such as sheet jam, double feed and blank feed.
