Title: Improvements in or relating to cable-tool drilling machines
IPC: E21B1/02
Filed: 1942-04-10
Abstract: 561,543. Boring earth. RUSTONBUCYRUS, Ltd. April 10, 1942, No. 4774] Convention date, May 5, 1941. [Class 85. In a cable-tool drilling machine comprising an arm oscillated by a crank and link, and alternately raising and lowering a cable carrying a drilling tool, means, such as a spring or counterweight, are provided and associated with the crank so that no position of unstable equilibrium of the system will coincide with a position of dead centre of the crank and link. In Fig. 2, the arm 18, pivoted at 19, is oscillated by a crank 25 and link 24, and carries pulleys 17, 20, over which passes the drill cable 15 ; a spring 31 connects the arm and link to bias the crank against taking up a dead centre position. In Fig. 3, the spring is replaced by a counter- ' weight 32 on the crank disc. In Fig. 1, a tractor truck 12 carries a frame 11 supporting the machine; an engine 28, through belt 29 and pulley 30, drives a shaft 27 from which may be driven the crank 25 and a bull reel 21 on which the drill cable is wound.

Title: Improvements in and relating to the coating of articles
Inventor: FOUNTAIN LESLIE ARTHUR
IPC: H01H1/021
Filed: 1963-02-06
Abstract: A method of manufacturing an electrical component comprising an insulating support member electrical contact member or members comprises forming said contact member and plating it with tin, assembling said contact member or members in said support and thereafter heating said contact member or members sufficiently to produce a bright coating of tin thereon.  The initial tinplating of the contact member results in a dull finish.  After assembly of the component, the contact members are heated to a temperature of which the tin coating becomes fluid and runs to a bright finish. The heating may be effected by an induction heating process, and the tin-plating by barrel plating.

Title: Improvements in or relating to collapsable photographic cameras
IPC: G03B17/42
Filed: 1938-02-17
Abstract: 491,001. Photographic cameras. KODAK, Ltd. Feb. 17, 1938, No. 4954. Convention date, Feb. 25, 1937. [Class 98 (i)] A folding camera of the kind in which locking means are provided between film feeding mechanism and a shutter release mounted on the camera body so that operation of the release member can only be effected if a fresh area of film has been moved into the exposure position, is provided with a movably mounted member connecting the shutter release with the locking means for the winding mechanism adapted to be actuated on collapsing the hinged bed or front cover of the camera. The film is wound by a ratchet wheel 8, Fig. 1, operated by an external knob. The wheel 8 turns through gearing a disc 14 carrying pins 16, 17. The pin 17 engages notches in a counting wheel 19. The ratchet wheel is engaged by a pawl 9 pivoted at 10 and provided with a projection 12 so placed that the pawl only engages the ratchet when the projection 12 enters a notch 13 in the disc 14. To make an exposure, a knob 26, Fig. 5, is pressed inwardly, thus moving a slidable plate 27 against the action of a spring 30. This plate carries an arm having an upstanding flange 31 engaging a flange on a Y-shaped lever 33 turning it about a stud 34 by which a pin 35 sliding in a slot' 36 in a lever 37 turns it about a pin 38 causing a flange 39 to actuate the trigger 40 of a shutter 41. As the knob is pressed inwards it engages a wedge-shaped flange 42 carried on a lever 43 which also carries a stud 44 adapted to engage a groove 45 to lock the operating knob 26 when the camera is closed. The lever 43 is carried by a bell-crank 47 pivoted to a stud 48 on the side of the camera normally pressed into the position shown in Fig. 1 by a spring 50, its movement being limited by a stop 53. In this position the pin 44 is clear of the knob 26 which is pushed into operative position by a spring 55 ; when, however, the camera is closed, the bell-crank is pushed into the position shown in Fig. 2 and the pin 44 will now engage and lock the knob 26. When the knob 26 is pressed and an exposure made, the lever 23 is turned and the hooked part 57 engages a pin 17 to turn the disc 14 sufficiently to release the pawl 13 so that the film may be wound. The lever 43 is prevented from further movement by a block 58, Fig. 4, engaging the hook 57 ; the wedge-shaped member 42 on the lower end of the lever 43 forms a stop and prevents the movement of the shutter release knob until the film feed is in such a position that the pawl 9 drops into the recess 13, thus removing the block 58 from the path of the hook 57.

Title: Process for the preparation of new compounds of therapeutic value
IPC: C07C311/37
Filed: 1936-02-18
Abstract: Aralkylamino - benzenesulphonamides are prepared by treating p-aminobenzenesulphonamide with an aralkyl halide or by hydrogenating the reaction product of p-aminobenzenesulphonamide with an aromatic aldehyde.  The aralkyl group may contain nuclear substituents such as hydroxyl and sulphonic acid groups.  The products possess therapeutic properties.  According to the examples: (1) p-benzylamino-benzenesulphonamide is obtained by condensing p-aminobenzenesulphonamide with benzaldehyde and hydrogenating the benzylidene-amino product in hot dioxane solution using a nickel catalyst; the same compound is formed when p-aminobenzenesulphonamide is heated with benzyl chloride in presence of calcium carbonate and water; (2) p - (o - hydroxybenzylamino) - benzenesulphonamide is prepared by condensing p-aminobenzenesulphonamide with salicylic aldehyde and hydrogenating the benzylidene compound in the presence of platinum at ordinary temperature in dioxane solution; the p-(p-hydroxybenzylamino)-compound is obtained in a similar way using a nickel catalyst; (3) benzaldehyde-m-sulphonic acid is condensed with p-aminobenzenesulphonamide and the resulting Schiff's base hydrogenated at ordinary temperature in presence of platinum to give p-(m-sulphobenzylamino) - benzenesulphonamide.  The samples furnished under Sect. 2 (5) comprise (1) p-phenylethylamino-benzenesulphonamide, prepared by heating p-aminobenzenesulphonamide with phenylethyl iodide in presence of calcium carbonate and water, and (2) p-phenylpropylamino-benzenesulphonamide, prepared in the same way but using phenylpropyl iodide.

Title: Electric transducers
Inventor: SULLIVAN NEIL
IPC: G01R19/12
Filed: 1958-02-14
Abstract: 830,633. Automatic speed control systems. SPERRY GYROSCOPE CO. Ltd. Feb. 14, 1958, No. 4964/58. Class 38 (4). [Also in Group XL (c)] The Figure shows a circuit for use in an automatic pilot for controlling deflection surfaces of an aircraft so as to maintain a given Mach number, the circuit being provided to prevent sudden changes in control when the automatic pilot is switched on. In operation, a reference signal is applied at 2 and a voltage from a pickup coil applied at 1 so that D.C. voltages appear at 7 and 8 which depend upon the amplitude and phase of the voltage at the pick-up coil. If a large voltage suddenly appears at terminals 7 and 8 when the circuit is switched into operation the magnitude of the charging current into capacitor 15 is limited by the transistor circuit 12 so that an appreciable period elapses before the voltage across the capacitor corresponds to the input voltage but if only a small input voltage appears the transistor circuit acts as a low resistance and the voltage across the capacitors rapidly follows that of the input voltage. When the circuit is switched off the contacts in. the switch circuit short-circuit the capacitors. Further discharge circuits for the capacitors are provided by circuits 19, 21 and 20, 22.
