Title: Motor vehicle auxiliary propulsion assembly
IPC: B60K6/48
Filed: 1980-01-31
Abstract: An auxiliary drive assembly (6), in the form of either a trailer, as shown, or alternatively a tractor unit, when coupled through plates (7) and clevis pins (8) to clevis connections (5) on a conventional vehicle (2) converts it into a composite hybrid vehicle (1) capable of being at the choice of the user propelled by either the original integral engine (3) of the basic conventional vehicle (2) or the auxiliary drive assembly. The auxiliary drive unit (6) contains an energy store, motor and power transmission means and is provided with a single road-engaging wheel arranged on a mounting pillar which allows the wheel to 'castor' as the vehicle assembly (1) turns corners. Operation of the auxiliary propulsion assembly is controlled from the driver's seat by means of auxiliary driving controls connected to the auxiliary propulsion assembly by means of a plug-in control cable (11). The plates (7), clevis pins (8) and clevis connections (5) permit articulation of the auxiliary propulsion assembly about a horizontal transverse axis whilst preventing articulation about a vertical axis.   A battery-powered auxiliary drive may be employed for a basic motor vehicle designed primarily for long- distance high-speed operation: when, for instance it is to be used for a period in low speed urban traffic or for door to door delivery work or motor fuel is in short supply. A battery-powered vehicle designed for slow-speed operation may have an auxiliary internal combustion engine powered unit capable of propelling it at a good road speed to the district in which its delivery round is to be run under battery power. <IMAGE>

IPC: A23B7/10
Filed: 1980-09-15
Abstract: A process for the treatment of vegetables prior to their presentation for sale comprising subjecting them, after cleaning and washing, to the following three successive stages of treatment, namely, an anti-oxidation treatment carried out in an aqueous bath of sodium metabisulphite at a temperature between 80 and 90 DEG C and for a period of 6 to 15 minutes, vacuum packaging in packs made from a plastics material at a temperature above 40 DEG C, and pasteurisation for a period of between 5 and 30 minutes at a temperature between 80 and 85 DEG C, the transfers from one stage to the next being effected without allowing the temperature to fall below 40 DEG C. The transfer of the vegetables from the anti-oxidation treatment stage to the vacuum packaging stage is preferably effected within 4 to 5 minutes, and the process is exemplified in relation to potatoes of the small "BINTJE" variety.

Patent GB-2068451-A (GB)
Title: Travel limiting devices
IPC: E05C17/16
Filed: 1981-01-19
Abstract: A device for limiting the travel e.g. of a door 4 in like manner to a conventional door chain has a bracket 1 to which is pivoted an arm 6. The arm has longitudinal grooves 7A, 7B with cut-outs 8A, 8B through which pegs 19A, 19B fixed to the door can enter the grooves, the opening travel of the door being limited by movement of the pegs to the closed ends 6A of the grooves.The arm 6 is furthermore movable longitudinally relative to the bracket 1 against the bias of a spring 10 and must be pulled radially outwards from the bracket against this bias to pass the pegs 19A, 19B through the cut-outs 8A, 8B. This action ensures that the arm is latched positively in its "on guard" condition. <IMAGE>

Patent GB-2113788-A (GB)
Title: Pipe couplings
Inventor: JEFFERSON DANIEL
IPC: F16L47/04
Filed: 1982-01-22
Abstract: The pipe coupling is designed for use with plastics pipes having a large coefficient of thermal expansion and in circumstances where large temperature changes are experienced such as in central heating systems. With existing seal arrangements the seal can be damaged during insertion of a pipe into a socket, and the pipe may be pulled from the socket by thermal contraction forces. The coupling described employs a tubular seal body (25) having an internal flange (24) at its inner end which abuts with the extremity (30) of pipe, and a cap nut (5) is threadedly engaged with external threads (7) on the pipe socket (6). The cap nut has an inwardly directed sleeve portion (12) having frusto-conical internal and external surfaces (15, 16) and provided with pipe gripping projections (27). The sleeve portion (12) cooperates with a frusto-conical bore wall (18) of the socket to provide a wedging action on tightening of the cap nut which also acts to confine the seal body. On insertion of a pipe into the socket, the sleeve portion (12) aligns the pipe end with the socket before the pipe meets the seal body. <IMAGE>

Patent GB-2119005-A (GB)
Title: Belt length adjustment device
Inventor: ANDERSON ALEXANDER BARRIE
IPC: A44B11/18
Filed: 1982-04-14
Abstract: The device consists of a frame 8, having spaced parallel bars 14, 16 around which a belt 4 is entrained, and a member 2 having a slot 6. The frame 8 is receivable in the slot 26 by virtue of its side brackets 12 being resiliently deformable and is retained in the slot by lugs 22. The frame 8 is pivotable in the slot 6 about a line of contact between a plate portion 10 of the frame and the surface of the member 2. A pull on the belt 4 at an angle to a plane perpendicular to the plane of the slot of less than o results in the belt moving freely through the device. However, when the angle o is exceeded the frame 8 pivots in the slot 6 and the belt 4 is snubbed at 28 and 29 (see figure 3) between the bars 14, 16 and the edges of the slot 6. The member 2 may be a part of a child's vehicle safety seat, a part of a releasable buckle, or a part of a belt- length adjuster. <IMAGE>

Patent GB-2126839-A (GB)
Title: Telephone apparatus
Inventor: HICKLING DAVID JOHN
IPC: H04M1/08
Filed: 1983-09-05
Abstract: The cradle switch for a telephone consists of a microswitch (10) activated by one end (16) of a lever (18) which is contacted and moved by the handset (14) when the handset is placed in position on the telephone body (20). The lever (18) is counterbalanced by a weight (24) so that the lever moves clear of the microswitch when the handset is removed. This weight is in its lowermost position when the telephone is in use and any sudden jolts caused, for example, by placing the telephone down quickly on to a surface will not result in the inadvertent operation of the lever and hence the microswitch. <IMAGE>
