IPC: B60G5/01
Abstract: 1,054,453. Vehicle suspensions. DELATTRELEVIVIER. April 9, 1964 [April 10, 1963], No. 14664/64. Heading B7D. A self-propelled or trailer vehicle and an auxiliary wheel set for attachment to the rear of the vehicle include equalizing means for distributing the load of the vehicle over the existing tandem wheels 26 and the auxiliary wheels 28, the equalizing means automatically coming into action simultaneously with means coupling the auxiliary wheel set to the vehicle. To attach the auxiliary wheels to the vehicle, pins 23 on the frame of auxiliary set are engaged by hooks 22 on screw jacks 20 connected to the vehicle by universal joints 21 and actuated by crank handles 24 to draw ogival studs 11 on a front frame member 8 of the auxiliary set C into frusto-conical holes 14 in a rear frame member 3 of the vehicle. The studs 11 are secured in the holes 14 when fully home by engagement with grooves 13 therein of reduced portions of apertures in locking plates 15 lowered by a hook inserted in a hole therein. Pushrods 41, 42 slidable in bearings 43, 44 engage one another simultaneously with engagement of the studs 11 in the holes 14 to equalize the loads exerted on the wheels 26 and auxiliary wheels 28 through levers 33, 34 held in contact with the pushrods by springs 45, 46. The pushrods 41 may comprise telescopic elements (Fig. 13, not shown) carrying support plates for coil or pneumatic springs or defining oil chambers connected by flexible piping oleo-pneumatic chambers. The wheels 26, 28 are arranged four-in-line on short axles pivotally connected to swing bars 27, 30 carried by the levers 33, 34. A cross-member (Fig. 10, not shown) for attachment to the rear of the vehicle to form an abutment for the pushrods 41 when the auxiliary wheel set is not in use includes an inclined portion acting as a continuation of a loading ramp, and forks for attachment of supporting struts. The rear wheels of the vehicle and the wheels of the auxiliary set are stated to be steerable by means not shown. In another embodiment the wheels of the auxiliary set are carried by a single axle.

The distance between corresponding grooves 9 and 6 may decrease towards the outer end of the anchorage, (Fig. 1), although the male and female members may become closer together towards the inner end, (Fig. 4). The grooves may be laterally ridged, (Fig. 1). The female member I may be separate from the bearing ring 4, (Fig. 1), or may have such a ring incorporated as an external flange, (Fig. 6, not shown). The grooves are basically semi-, or part-circular in cross-section, but at their deep ends they may have semi-circular bases with parallel side walls, 21 and 22 (Fig. 7).

Abstract: 1,084,366. Removing moulded articles. PENNSALT CHEMICALS CORPORATION. Nov. 4, 1964 [Nov. 6, 1963], No. 45001/64. Heading B5A. An injection or transfer moulding press 12, 14, Fig. 2, has a stripper comb assembly 34 which on actuation delivers the moulding parts to one receptacle and the sprue and runners to another receptacle. The stripper comb assembly comprises a comb unit 62, 64 and a tray 114 selectively movable to the space between the mould plates 12, 14 to receive respectively the sprue and runners 30, 32 and the mould parts 28 which have been separated and ejected from the mould cavities by air jets and jector pins. The tray 114 in returning to its initial position takes along the comb unit. A roller or rollers on the tray move along inclined tracks 118 so that the moulded parts are delivered to one receptacle and a scraper blade 90 knocks the sprue and runners off the comb unit into another receptacle.

Abstract: 1,226,382. Magnetic switch. C. E. COOK. 12 May, 1969 [10 May, 1968], No. 22357/68. Heading H1N. [Also in Division G4] An electric switch mechanism, which may be part of a launderette coin-feed mechanism, has contacts operable from a first to a second condition at an operating point in the forward movement of an actuator 1 which in its return movement travels past said operating point to a resetting point at which the contacts are restored to. said first condition and the distance . moved by the actuator between said operating and resetting points is greater than the distance between successive teeth of a series of teeth 4 which co-operate with a pawl 5 to inhibit reversal of the actuator 1 during its return stroke. The actuator is a coin carrier which can be manually slid into a housing 2 against the bias of a spring 8. During the initial forward movement of the actuator coins carried thereby are examined by fingers and pawls 3 and if found correct the sliding actuator 1 is allowed to continue its movement through a position where a space 6 passes a spring biased pawl 5 and an edge 6a of the space puts the pawl in the Fig. 1 position to engage the ratchet teeth 4 and prevent withdrawal of the actuator 1. In its continued forward movement the actuator reaches a position A, Fig. 4, in which a permanent magnet 9 thereon closes the contacts of a reed contact unit 10 and thereafter holds them closed to the end of the forward movement to position 9<SP>1</SP>. On return movement of the actuator 1 the pawl 5 is reversed and ensures complete withdrawal of the actuator before it can be moved inward again. During the outward movement the contacts of the contact unit 10 open when the magnet reaches the point B and the distance # between points A and B is greater than the distance between the teeth 4 so that the reverse movement allowed by the ratchet and pawl is insufficient to allow the contacts to be reclosed once they have opened. The contact unit and magnet may be replaced by a microswitch having a long lever or mounted at an angle to the actuator to ensure a sufficient differential (Fig. 5, not shown). The contacts may be in a relay circuit with a capacitor which discharges slowly so that a relay operating pulse cannot be produced on quick reclosing (Fig. 3, not shown). The magnetic switch arrangement may include a magnetic shield, not shown.

Abstract: 1,250,740. Image pick-up tubes; semiconductor targets. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 12 March, 1970 [15 March, 1969], No. 8299/71. Divided out of 1,246,260. Headings H1D and H1K. The target of a camera tube comprising an N-type semi-conductor substrate provided with a mosaic of P-type regions and with insulation between the regions, is characterized by the provision of a resistive layer formed of chromium oxide or a mixture of chromium oxide and nickel oxide having a resistance of 10<SP>12</SP>-10<SP>16</SP> ohms per square. In order to avoid capacitive effects the resistive layer should preferably be interrupted where it overlies the centres of the P-type regions. Electrode processing.-A layer mainly consisting of chromium may be vapour-deposited from a chromium nickel spiral, the substrate being at about 200 C. The target is then heated, e.g. to 400 C., in an oxidizing atmosphere (air), e.g. for ¢ hour. The thickness of the coating is about 0À05 microns or less and its resistance depends  on the temperature and duration of the oxidation process. In order to provide gaps in the coating over the P-type regions, the deposition may be made through a grating of parallel wires which covers these regions; the vapour deposition is performed in two different processes between which the grating is rotated through 90 degrees.
