Title: Plastics stoppers
IPC: B65D39/04
Filed: 1971-12-08
Abstract: 1416865 Plastics stopper P KEARNEY 8 Dec 1972 [8 Dec 1971] 57129/71 Heading B8T A hollow plastics stopper 10 made of equal parts of high and low density polyethylenes has a cylindrical body and an end flange 18. The external wall of the body carries four equally spaced flexible annular flanges 20-23 of varying thickness and diameter. Flange 23 remote from end flange 18 enters the container neck first, and is of such a diameter as to wipe the inner surface of the neck. Flange 22 with a slightly larger diameter, enters the neck next and completes the wiping action. The third and fourth flanges 23, 24 which have thickened roots for strength (25, 26) Fig. 1 (not shown) have larger diameters than flange 22 and grip the inner neck of the container. The distances between the flanges is such that the flexible ends do not touch one another in use. Stopper 10 may be used in conjunction with a liquor dispenser 32 and an opaque stopper shield 35 which consists of an opaque body 36, a truncated cone end section 37 and a retaining flange 38, and is assembled by placing the shield 35 on the dispenser 32 with a washer 33 in position and placing stopper 10 over the dispenser pipe 31 and pushing the assembly on to the open neck of a liquor bottle 30.

Abstract: 1,214,900. Making electrodes; electric cells. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. 9 Dec., 1968 [8 Dec., 1967; 27 Sept., 1968], No. 58477/68. Heading H1B. A process for making an electrode comprising a cup having active material on the walls thereof, comprises introducing a rod-like mandrel into the cup, distributing pulverulent active material in the annular space between the mandrel and the cup, compressing the active material to render it mechanically cohesive and removing the mandrel from the cup. The cup may be of zinc and the active material may be dry amalgamated zinc powder. Compression of the active material is achieved by reducing the diameter of the cup. This may be achieved by passing the cup through a reducing ring of slightly smaller diameter than the cup or by using the apparatus shown in Figs. 15 and 16 where Fig. 16 is a cross-section taken at BB. Cup 1 containing active material 5 and mandrel 22 is compressed by the sectors 32 of tapered split ring 31 when member 33 with a hole of equal taper is moved upwards wedging the sectors together as shown in Figs. 15 and 16 compressing the cup by a radial force only. When the cup has been compressed member 33 is lowered allowing springs 35 to open the split ring so that the cup can be removed. Assembly of the cell is completed after removal of the mandrel by insertion of a depolarizing dolly and carbon rod electrode, the addition of electrolyte and a further reduction in the diameter of the cell.

Title: Vehicle speed control systems
IPC: B60K31/18
Filed: 1979-06-21
Abstract: A vehicle speed control system has a circuit 22 producing an actual speed-dependent signal (Vs), which is passed through a control unit 24 provided it is greater than a predetermined low limit. A memory 36 is temporarily connected by a driver to the output of the unit 24 to receive and store the signal Vs and form a speed reference Vm. A comparator 42 then compares a signal Vf dependent on the filtered value of Vs with the reference so as to produce an error signal dependent on any difference between them. The speed of the vehicle engine 10 is thus adjusted so as to reduce the speed error to zero. An indicating lamp 50 is connected to be energised via a comparator 30 when the speed-dependent signal Vs is fed into the store 36 and is positioned so as to be capable of providing an indication of this to the driver. The lamp 50 is extinguished when the driver puts the system out of operation eg by use of brake, clutch or gearbox. <IMAGE>
