Title: Safety belt across the shoulder which twines all bodies whether an adult or a child
IPC: B60R22/02
Filed: 1979-09-17
Abstract: Safety belt across the shoulder for front and back seats which twines all bodies whether it is an adult or a child. The belt is formed either with a single strap folded in three plies: 1 abdominal containing the reserve, 2 thoracic, 3 dorsal. Either it is comprised of two straps, one forms the abdominal ply with a reserve and the thoracic ply with a second reserve which is absorbed by a reel and a second strap which forms the dorsal ply, a shoulder buckle fixed to said dorsal ply connects the thoracic ply, without hampering the automatic absorbsion of the frontal ply by the reel. The dorsal ply rests on the edge of the back, without modifying at all the conventional unbuckling and buckling. Prior to starting, to be at ease, some of the strap may be extracted and a detachable retaining buckle impedes the continuous retraction of the reel. In case of an accident, all the attaching points and the anchoring points are of the instantaneous unhooking types, even if the weight of the body bares onto the plies. The belt is appropriate for use in a stretched out or lied down position. In case of overturning of the vehicule, there is no risk for the body to be strangled, projected, or to knock against the top.

Title: Improvements relating to bookbinding
IPC: B42D1/00
Filed: 1980-08-28
Abstract: A plurality of page sheets (1), of paper, at least one of which has fusible thermoplastic particles dispersed therein, are sewn together along a seam (2) by two threads (4, 5). The thread comprises one or more thermoplastic elements which are fusible during a bonding step and one or more elements which are not fusible during the bonding step. The bonding step, for example high frequency bonding, is such that the threads become fused together at thread crossing locations in the seam and fused to the plastics- containing page sheet or sheets. Thus a book with improved security against tampering with the pages thereof may be produced. Various embodiments are disclosed, in particular a book cover may be bonded to the pages at the same time as the threads are bonded, by suitable choice of the material of the book cover or a lining thereof. The pages may be printed all over before seaming with a fugitive ink containing fusible thermoplastic particles, as in the case of a Bank Book, in which case the threads also become bonded to the ink. <IMAGE>

Title: Spring energy storing and/or absorbing devices
IPC: H01H3/30
Filed: 1981-03-04
Abstract: Two parts (not shown) are moved by a spring energy storing device by means of a movable arm 16 which is connected by a pin and slot connection 84, 86 to the device. The device includes a telescopic part formed by a pair of congruently arranged T- shaped members 66 (not shown) and 70 having heads 74 and a T-shaped member 68 connected to a fixed bracket 82 at an end thereof remote from its head 72. Elongate stem portions of the T-shaped members are arranged in parallel overlapping relation and are encircled by a compression spring 76 whose ends act on the heads 72 and the head 74 respectively. When the device is released from an energy storing condition (Fig. 1), the spring 76 urges the heads 72, 74 apart and thereby pulls the arm 16 towards the bracket 82. The members 66 and 70 are arrested by engagement of their heads 74 with the bracket 82, but overrun movement of the arm 16 is permitted by the connection 84, 86. A surface 16' on the arm 16 then acts on the head 72 to move the member 68 as permitted by the connection 88, 90 thereby compressing the spring 76 again to absorb the excess kinetic energy of the arm 16. The device is described in relation to a circuit breaker, but is stated to be applicable to other arrangements in which two parts are movable between stationary positions. Examples given are snubbers for boat moorings towbars for trailers and fire or safety door closing devices. <IMAGE>

Title: Electric cable reel
IPC: B65H75/48
Filed: 1981-03-05
Abstract: A reel 1 for electric cable has a coil spring 11 secured within its hollow hub 3 which acts both as the electrical connection between an electrical supply in or on a fixed shaft 7 passing axially through the hub and the inner end 20 of the cable and also to cause automatic rewinding of the cable. The outer end of the spring is trapped between the head of a bolt 15 and the inner surface of the hub while the inner end of the cable is secured by a nut 19 to that portion of the bolt which lies beyond the outer surface of the hub. The spring is wound up as the cable is withdrawn and the hub caused to rotate. All electrical conductive parts may have an insulating covering to render the reel waterproof. A lockup device, electrically or manually operated, may be provided to prevent unintended rewinding. In the case of several cables or a multi-core cable being present, a corresponding number of springs are provided. <IMAGE>

Another tube 32 is connected at one end to the other end of the cylinder and the other end of said tube is connected to a bellows element adapted to be manually operated to be compressed and released. This produces air pressure and suction operable upon the plunger to effect the sounds simulating natural heartbeats. <IMAGE>
Patent GB-2105821-A (GB)
Title: Compressor valve
Inventor: LAWSON STUART
IPC: F01L3/20
Filed: 1981-07-10
Abstract: A compressor valve has a valve seat and a pressure responsive valve member 46 movable to open and close an opening 38 in the seat. The seat has a relieved region 64, 68 extending outwardly from the location of the opening so that, when the valve member closes the opening, sealing contact between the valve member and the valve seat is substantially confined to a narrow area encircling the relieved region and the opening and substantially the entire surface of the valve member within the narrow area is exposed to the pressure in the opening. As a result, the area of sealing contact is reduced by comparison with a standard compressor valve and the area of the valve member on the side of the seat exposed to pressure is increased. Alternatively the valve member may be relieved. <IMAGE>

Inventor: PARKER MICHAEL ANDREW
IPC: G11B20/14
Filed: 1981-09-15
Abstract: An encoder for converting an input binary word into an output word with a greater number of bits has a first coding section (PROM 1, I1) responsive to a first group of the input bits (L1, bits 1-9) to produce a first group of output bits (L2, bits 1-10), whilst the remaining output bits are produced by a second coding section (logic CL, PROM2, PG), in dependence on the remaining input bits and on the first group of bits and/or (as shown) outputs (j, k) of the first coding section. A coding method involves generating output words in each of which (a) there are a predetermined number of binary ones and zeroes, (b) the number of consecutive identical bits in each output word is not more than a predetermined limit and (c) the numbers of consecutive identical bits at the beginning and end of the output word are not more than respective ones of a pair of predetermined numbers the sum of which is equal to the said predetermined limit, whereby the number of successive identical bits which can occur in a serial data transmission of successive output words does not exceed the said predetermined limit. <IMAGE>

Title: Control of fuel supply in i.c. engines
IPC: F02B3/06
Filed: 1981-09-16
Abstract: A liquid fuel pumping apparatus for fuel to a multi-cylinder engine has a plurality of outlets for connection to the injection nozzles of the engine. The apparatus includes a spill passage 29 and a spill control valve 30 which is electrically controlled. The valve 30 is closed to cause fuel from a high pressure pump to be delivered through the outlets, fuel being supplied by the high pressure pump to the inlets in turn. A pressure transducer 35 provides signals indicative of the pressures attained in the various outlets curing delivery of fuel therethrough. One of the pressure signals serves as a standard and the other signals are compared with this signal and correction signals are computed in a microprocessor which vary the time the spill valve is closed when fuel is supplied to those outlets to which the signals pertain. In a modification a mechanical operation of the spill valve can be provided to allow the engine to be driven in emergency conditions. <IMAGE>
