Abstract: 993,167. Binding posts; couplings; mounting terminals. C.C.L. Ltd. Aug. 1, 1963 [May 25, 1962], No. 20148/62. Heading H2E. A resistive or reactive circuit component has a mounting pin of sheet metal strip shaped to produce a greater cross-section between its ends than at its free end, so that when the pin is inserted in a hole of suitable size on a panel, the component is held spaced from one surface of the panel while the pin is soldered to printed wiring on the other surface of the panel. The pin may be tubular with an intermediate peripheral collar, or, as in the capacitor shown in Fig. 1, tapered; each pin 4 is made from sheet steel or preferably brass, phosphorbronze or copper alloy, and comprises a tab 7 which is connected to a rivet 3 which is connected inside the metal casing 1 to a flexible ribbon lead extending from a rolled foil electrode. Other embodiments (not shown) have two pins and one pin respectively; in the latter case, a flexible lead emerges from the end of the casing remote from the pin and is passed through a hole in the printed circuit board and soldered to wiring thereon.

Title: Improvements in training gear for multiple gun turrets
IPC: F41A27/12
Filed: 1927-07-29
Abstract: 275,615. Schneider et Cie, and Compagnie des Forces et AciÚries de la Marine et d'HomÚcourt. Aug. 6, 1926, [Convention date]. Mountings.-A device for absorbing shocks in the training-gear of multiple-gun turrets when a lateral gun is fired, comprises a spring-controlled hydraulic brake which is operated through a rack or worm from the crown wheel of a differential gear interposed in the motor-driven shaft which serves to train the turret. The driving motor can thus remain connected to the turret during firing. In the form shown, the gun is trained by a worm gear 6, 5 acting on a shaft 3 driving a pinion 1 gearing with the training ring 2'. A differential gear mounted in a break in the shaft 3 has its planetary pinions x connected to a wormwheel 8 gearing with a worm 10<a> on a transverse shaft. One side of this shaft is connected to a double-ended spring device 12a and the other to an hydraulic dash-pot 15<a>. When shocks occur, the worm moves bodily to either side, but, when training corrections are applied, the worm is rotated by a motor 17 through chain-gearing 19. The worm gear may be replaced by a rack and pinion.

Title: Improvements relating to tine drag harrows
IPC: A01B19/02
Filed: 1922-07-24
Abstract: 203,139. Buswell, C. J., and Wilder, H. H. July 24, 1922. Harrows; tools, mounting rigidly. - In drag harrows in which sets of tines are mounted on axles that are allowed to turn periodically to deposit collected weeds &c., as described in Specification 185,509, the axles are arranged to turn independently of one another and are released simultaneously, or in alternate pairs, or successively, by means of a single operating-lever. The tines 2 are clamped on square or circular shafts 1 in pairs by bolts passing through them. When the shafts are circular they are provided with recesses to receive ribs on the tines. The shafts fit into bushes mounted in bearings dependent from members 5 bolted to the longitudinal bars 6 of the harrow. The central bushes are mounted in stepped members 9 held in place by collars 10. toothed wheels 8 in the bushes engaging with internal teeth on the members 9 to allow of adjustment of the angle of the tines. A bell-crank pawl 12 normally engages with one of the oppositelydisposed stepped parts of each member 9 and with a roller 13 on a spring-controlled lever 14 connected by a rod 17 and slotted link bar to the operating-lever 18, which may be moved directly bv hand or indirectly by means of a cord 19 extending to a tractor or to the rear of the harrow. In order that movement of one axle may operate the next, projections 20 on the member 9 may operate a bell-crank lever 21 which engages with an arm 22 on the lever 14. Stops 16 limit the movements of the pawls 12 and levers 21. In the arrangement shown, the axles are released in pairs, two of the levers 14 being connected to each of the two rods 17. When the lever 18 is pulled forward into the position shown in full lines one of the rods 17 is moved and releases the first and third axles, the others being subsequently released by means of the bell-crank lever 21. When the lever 18 is pulled further forward and secured bv a pawl 27 engaging in a notch, the axles are released approximately simultaneously and are free to turn together and continuously. The axles are locked again by releasing the lever 18 after pulling it forward until the weighted dog 27 has passed over a rounded portion 28 of the locking- quadrant 25 and into a depression 29. The springs 23 then pull the lever sharply back to its initial position, the dog 27 jumping the notch in the quadrant. Dummy tines may be provided to insure rotation of the shafts. In a modification, by moving the lever to three different points, one only of the tine-releasing mechanisms may be tripped, or alternate releasing mechanisms, or all the mechanisms. According to the Provisional Specification, either one or two operating-rods may be provided for releasing the tines, or anv set of tines may be released separately by wires or cables; also the teeth of the adjusting mechanism may be on adjacent faces of discs, and means may be provided for preventing backward rotation of the tine axles.

The invention thus provides cheap throw-away nipples and containers which may be maintained in sterile condition if packed in a peelable outer layer such as 24 (Fig. 2). Materials from which the nipple/container may be formed are polyethylene/nylon and polypropylene/nylon laminates. The resilient plug may be a foam or sponge of polyurethane, polyethylene, natural latex, nitrile rubber, cellulose or vinyl chloride/vinyl acetate copolymer.

Title: Improvements in thermionic tube electromagnetic wave generating arrangements
IPC: H03B5/10
Filed: 1920-07-10
Abstract: 148,447. Ges. f³r Drahtlose Telegraphie. Sept. 9, 1918, [Convention date] Electric oscillations, producing.-In a thermionic generator in which oscillations of either one of two frequencies may be produced, oscillation at the undesired frequency is prevented by the insertion of additional elements such as an auxiliary condenser, inductance, or both, or a rejector circuit syntonized to the undesired frequency, whereby the tube coupling is rendered more favourable to the generation of waves of the desired frequency. Fig. 3 shows a typical arrangement, the anode and grid circuits of the thermionic tube 1 being coupled to the oscillatory circuit 7<1>, 9, by means of inductances 3 and 4 respectively. The tube may oscillate at either of two frequencies according to whether the circuits formed by the inductances 3 and 4 with the parallel anode-filament and grid-filament capacities, act resultantly as inductances or capacities in the main oscillatory circuit 9, 7<1>. A mathematical analysis is given whereby the nature and magnitude of the additional element or elements may be determined. In the arrangement shown, oscillation at the higher frequency is prevented by the insertion of a condenser 14 in parallel to the grid cathode space or by connexion of an inductance 15 in the grid circuit. The same result is obtained by the insertion in the connexion to the grid of a separate tuned circuit syntonized to the undesired frequency. The invention may be applied to other circuit arrangements in a similar manner, having regard to the frequency to be suppressed and to the effects of interposed inductances and capacity.

A synchronizing impulse of greater intensity than the picture signals is sent at each oscillation of a scanning mirror 5, Fig. 1, by arranging for the beam of light to overlap the edge of the picture on the film 2. The opposite edge, which may contain a sound record, is shielded by a screen 14, and the lens 11 is so arranged that the light always falls on the same part of a photoelectric cell 10.
