Abstract: 1399492 Liquid receptacle assemblies SHISEIDO CO Ltd 7 June 1972 [8 June 1971 (2) 14 Jan 1972] 26503/72 Heading B8T  A receptacle 1a has a rotatable cap 2 which is displaced upwards when rotated from its closed position to establish liquid communication between the aperture 3a of the cap 2 and the aperture 8e in a closure plug 8 fitted in the container neck 6, means being provided to hold the cap in resilient engagement with the body 1 to maintain the relative position of the cap and neck in the closed and open positions of the cap 2. In Figs. 1-7, the deformable receptacle 1a is of elliptical cross-section and has a neck 6 of circular cross-section, and the cap 2 has a side wall 2a whose lower edge is elliptical and a circular top wall 3c. Rotation of the cap 2 produces a camming of the lower edge of the side wall 2a out of engagement with the shoulder 7a and up the surface 7. The cap 2 has two depending part-cylindrical flexible members 5 provided with ribs 5a which co-operate with a locating rib 6b and a cap retaining flange 6a on the neck 6 of the receptacle. Upward displacement of the cap 2 forces the lower rib 5a past the rib 6b by flexing of the members 5. The closure plug 8 is held by a rib 8c engaging a groove 6c in the neck 6. The inner cylinder 8b is engaged by a cylinder 4 depending from the cap wall 3c, and is provided with the liquid outlet 8e and a projection 8f which is engageable in hole 3b to close the exit hole 3a. In a similar embodiment, Figs. 9A and 9B (not shown), the receptacle has a hexagonal cross-section, and the upward displacement of the cap is also obtained by replacing the circular ribs 5a and 6b with spiral ribs which remain engaged (the flexible members 5 being replaced by a cylinder). The inner cylinder 8b of the closure plug 8 is formed with a circular rib engaging a groove in the depending cylinder 4. A pair of outlets 8e is provided in the plug 8, and the projection 8f closes the hole 3b when the shoulder of the plug 8 engages the top wall 3c. In Fig. 8 (not shown), the embodiment of Figs. 1-7 is modified. The depending cylinder is omitted and the closure plug 8 is replaced by a single cylinder having a central liquid outlet which is closed by a further plug carried by the cap on spiders in the exit hole 3a. In Figs. 10 and 11 (not shown), the embodiment of Figs. 1-7 is modified. The shoulder 7 of the receptacle is horizontal and provided with inclined cam surfaces which co-operate with vertical elements depending from the cap top wall 3c, in order to effect the vertical displacement of the cap 2.

Title: Control circuits for electrically driven vehicles
IPC: B60L11/18
Filed: 1973-06-06
Abstract: 1480062 Automatic current control LUCAS INDUSTRIES Ltd 31 May 1974 [6 June 1973]  27009/73 Heading G3R [Also in Division H2] A control-circuit for the D.C. motor 12, 13 of an electrically-driven vehicle comprises a thyristor chopper and commutating circuit 15-19 con trolled by members 14, 26-38, 40 to maintain the motor current at a desired value and to provide minimum "on" and "off" times for the thyristor 15, as described in Specification number 1480055, and a circuit consisting of members 42-49, 51-59 and operative firstly to determine a maximum "on" time for the thyristor 15, in the event that the actual current does not reach the desired value set by adjustable resistor 26, and secondly to ensure that, should the first operation occur during regenerative braking, the minimum "off" time of the thyristor 15 is subsequently increased. The first operation is provided by a transistor 43 controlled by the output of amplifier 33 to turn off and on as the thyristor 15 is respectively turned on and off by amplifier 33 changing state. If no pulse appears at the input of amplifier 33 to change its state to turn off thyristor 15, capacitor 47 charges sufficiently to five uni-junction transistor 48 and so cause capacitor 54 to charge and apply a pulse via transistor 55 and members 58, 59 to amplifier 33, thus causing it to change state and turn off thyristor 15. When the above operation occurs during motoring, a braking device 56 is open and transistor 55 acts as a diode. During regenerative braking however the device 56 is closed to connect transistor 55 to the line 41 and cause it to act as an emitter follower whereby, when the above operation occurs, the pulse applied to amplifier 33 has a leading edge causing the amplifier to change state and turn off thyristor 15 (as before) and has an increased length to delay its termination and so correspondingly increase the minimum "off" time of the thyristor 15.

The nuts rest on a platform 23, Fig. 4, and when one is stationery between the cutters it is clamped by members 24 which are pressed by springs 34, Fig. 5, against the grippers 4. An upper clamp 38 may also be actuated to secure the nut against the platform. The cutters 27, whose spindles 26 are carried by slidable brackets 25, are then fed inwards by a cam 35 and levers 36 to cut the opposed slots in the nut and are withdrawn rapidly by springs 37 when the levers pass the highest part of the cam, after which the members 24 are pushed back against their springs by a cam 32 on the same shaft 31 as the cam 35. The slotted nuts are moved on by the chains 2 until at the point B the platform 23 terminates and the nuts are allowed to drop between grippers 4a on chains 2a similar to the chains 2 but arranged at right angles thereto and at a lower level. The chains 2a carry the nuts to a second pair of cutters 27a which are operated in a similar manner to the cutters 27 in order to cut a second pair of opposed slots in the nuts. The grippers 4 are shaped to engage the corners of the nuts whilst the grippers 4a engage the flat sides. The cutter spindles are driven by bevel gears 29 splined on shafts 30, 30a connected by bevel gearing 39, the shaft 30 being driven. On leaving the cutters 27a the nuts pass to a tapping mechanism 40 for removing burrs from the threads and are ejected from the machine at C. Several pairs of cutters may be provided at each station, the conveyer chains then making larger movements at each step so as to supply a new set of nuts to the cutters. '
