Title: Electrical connectors
IPC: H01R13/17
Filed: 1972-05-22
Abstract: 1393999 Two part couplings FUTTERS (LONDON) Ltd 26 April 1973 [22 May 1972] 24013/72 Heading H2E A plug to grip resiliently the walls of a socket comprises a longitudinally grooved shank 50 carrying a bow spring 54 projecting outwardly from the groove 70 and held in place by insertion into a diagonal hole 72 at the entering end of the plug, and by a transverse hole 76 at the other end. The spring 54, made of stainless steel wire, is shaped so that after insertion in hole 72, it must be flexed with pliers before its other end can be inserted into hole 76, where it is initially retained by friction. Shank 50 is made integral with body 56, and after insertion of the spring in the shank, end 74 is inserted into the mouth of insulating housing 58, and is pushed home so that the shank protrudes and shoulder 66 abuts the rim of aperture 68 in the housing. The spring is flexed inwardly in the groove during its passage through the aperture, afterwards springing outward, although remaining trapped by the end of the housing. A cable can be inserted into the base of the body 56 and clamped by a screw (not shown) in hole 60, aligned with hole 61 in the housing. A second transverse hole 63 in body and housing allows the insertion of a similar transverse plug to further connexion of circuits. A second embodiment (Fig. 1, not shown) allows for insertion of the second plug from the rear. Other embodiments allow for the retention of the spring at the entering end of the shank by insertion of the spring into a hole parallel to the shank, either from end face 74 or within a deepened groove stopping short of the end. One embodiment shows the other end of the spring trapped tightly between the shank and the internal wall of a non-integral metal body into which the shank and spring are forced. In all embodiments the spring is deformed out of its natural shape in the course of insertion into the plug.

Abstract: 1,185,944. Urea. CHEMICAL CONSTRUCTION CORP. 20 May, 1968 [22 May, 1967; 13 Nov., 1967], No. 24026/68. Heading C2C. Urea is synthesized by the reaction of CO 2  and NH 3  at elevated temperature and pressure in which NH 3  and CO 2  are removed from the urea product stream containing excess NH 3  and CO 2  by stripping a heated product stream with a stripping gas comprising a mixture, at least in part, of recycled stripped gas and at least a portion of the reactants, CO 2  or NH 3 , required for the urea synthesis. Stripping is preferably at urea synthesis pressure, usually from 120 to 250 atmos. Inert gases inherently present in the CO 2  as impurities at from 0À5 to 10% by volume may be used in stripping. The stripped gases may be recycled as an aqueous solution after condensation, or in the gaseous state they may be recycled either by direct pressurizing or by injection of a reaction component to carry them through. Stripping preferably takes place in two stages, in the first stage NH 3  being added, and in the second CO 2 .

Abstract: 704,367. Vehicle rest bars. SANDFORD, L. G., and SANDFORD, D. I. E. Sept. 23, 1952 [Oct. 19, 1951], No. 24402/51. Class 108(2) An anti-tipping device for a perambulator or the like vehicle comprises fore and aft ground-engaging supports carried at opposite ends of a connecting member adapted to be secured to the vehicle chassis for pivotal movement about a longitudinal axis, the device including means for releasably holding the ground-engaging supports in operative positions at which overturning of the vehicle in either the fore and aft direction is prevented. In the arrangement shown fore- andaft rest bars 7 and 8 are formed at the ends of a connecting rod 9 which is mounted for pivotal movement about the longitudinal axis of the rod, on bearings mounted below wheel axles 3 and 4. The 'aft bearing comprises a wooden block secured between metal plates 12, 12, having upper flanges 13 by which the bearing is adjustably secured by screws 15 to straps 17 carried by the axle 4. The rod 9 passes through a hole in the block 11 and a cranked portion 20 of the rod is located, in the operative position of the rest bar, in a groove 21 in the block, in which the rod is retained by a spring 22. A similar bearing is provided for the fore end of the rod 9, except that the block 11 is of plain rectangular form. The range of adjustment provided by the screws 15, may be increased by reversing the plates 12 so that the screws 15 may be engaged in flanges 14. In operation, movement of the rest bars from the operative to the inoperative positions, is effected by rearward movement of the rod 9 against the spring 22, to free the portion 20 from the groove 21, followed by a swinging movement of the rest bars about the axis of the rod. The swinging movement may be assisted by the spring 22 if the latter is arranged to act also as a torsion spring. The rest bars 7 and 8 may be formed of two telescoping parts to permit adjustment of their lengths. In a modification. Fig. 6 (not shown), the bearing for the fore rest bar extends above the front axle. In another arrangement. Fig. 7 (not shown), the rod 9 is supported by downwardly turned ends of a plate adjustably supported from the front and rear axles. the rear end of the plate being formed with a horizontally extending fork-shaped flange providing a holding means for the cranked portion 20 of the rod 9. The device may be adapted for co-operation with wheel brake applying mechanism.

[Also in Group XL (c)] A cathode-ray tube for forming pulse trains comprises an electron gun, a secondary emitting target, a plurality of guide electrodes and a plurality of collecting electrodes, means for deflecting the beam of electrons and means for applying to the guide electrodes voltages synchronized with the deflecting means to direct the secondary electrons emitted from the target to each of the collecting electrodes in turn. Electrons from a gun 6 are directed on to the flat end wall 3 shown in plan in Fig. 2. The beam is deflected to follow a circular path 9 across a fluorescent screen; in front of the screen are two groups of guide electrodes 8, one group being connected to the wall coating 13 which forms the final anode and the other group being connected to the terminal 11 which passes through the end wall 3. By applying a square wave to one of the groups of guide electrodes secondary electrons emitted from the fluorescent screen can be directed to each of the collecting electrodes 14 in turn. The electrodes 14 and their connections 15 may be formed by applying coatings of silver round the edge of the cylindrical part 2 of the envelope and subsequently joining the end plate 3 to the cylindrical part 2 by a glass solder joint. Further secondary emitting electrodes may be arranged to obtain multiplication of the emission from the screen before the electrons reach the collecting electrodes.

Class 40 (ii) In an improvement or modification of the mechanism of the parent Specification, the take-up drum 5 is provided with an individual driving motor 140 which is controlled by means whereby intermittent rotary movement is transmitted to the take-up drum 5. The said means comprise circuit elements in series with the motor winding consisting of a negative temperature coefficient resistor 142 and a feeler-operated switch 143. When the magnetic tape 1 starts to became taut, a feeler member 145 in contact with the tape opens the switch 143 against the tension of a spring 144 and stops the motor 140. Almost immediately the tape slackens and releases the switch 143 so that the circuit is restored but, owing to the negative temperature coefficient of the resistance 142, full voltage is not restored to the motor for some moments thereby ensuring a more gentle acceleration. Specification 678,358 also is referred to.
