Abstract: 463,994. Mercury switches. CHILOWSKY, C. Jan. 3, 1936, No. 267. Convention date, Jan. 5, 1935. [Class 38 (v)] [Also in Group XX] Apparatus for indicating intensity of light or for utilizing variations in light intensity to control the closure of an electric circuit, comprises a closed chamber containing a liquid, such as HCl, which is decomposed by electrolysis into constituents capable of recombining under the action of light, so that the gas pressure within the chamber depends on the intensity of the light incident upon the chamber ; the pressure being transmitted to a mercury column &c. which is utilized to indicate the gas pressure or to control the completion of an electric circuit. The form shown in Fig. 1 comprises a transparent vessel 1 communicating with a U-tube 3. The vessel 1 contains HCl &c. resting on mercury in the tube 3 and is provided with electrodes 2, 2<1> connected to a battery 4 for decomposing the electrolyte into its constituents. The action of the light incident on the vessel 1 is to recombine the constituents to form HCl which dissolves in the liquid so that the gas pressure in the vessel becomes less as the intensity of the light increases. The mercury level thus depends on the light intensity and can be used to measure it or, as shown, the mercury may be adapted, when a predetermined gas pressure is attained, to close an electric circuit, such as that of a lamp 10. The mercury may be maintained at a negative potential, as shown, to prevent its corrosion by chlorine, or a column of inert material may be provided between the mercury and the electrolyte. A lens may be used to concentrate light on the vessel 1. In Fig. 8 the vessel 1a has a flat form and the electrolyte is separated from the mercury by a flexible fluidtight partition 31 which may form one of the electrodes. In the light-actuated switch shown in Fig. 14, the mercury column is provided with three contacts 36, 37, 38 of which the contact 37 is connected to the lamp &c. to be controlled. The contact 36 is connected to a resistance 39 forming a shunt for the electrolytic current so that after the mercury reaches this contact its movement is retarded. When the mercury reaches the contact 38 the electrodes 2, 2<1> are shortcircuited.

[Class 9 (ii)] A smoke-producing pyrotechnic device has an outlet for smoke at the upper end and encloses a weight at the lower end the weight and outlet being offset in opposite directions from the vertical axis to prevent rotation of the device when floating and to keep the smoke outlet at the highest point of the casing. The cylindrical paper casing 10 is closed at the base by a cardboard disc 11 on which a weight 12 eccentrically placed is held in position by a smoke-producing composition 13 over which is an igniter composition 14. A cardboard plug 15 closing the top of the casing has an eccentric opening 16 forming a smoke outlet. A delay fuze 17 enclosed in a tube extends downwardly from the plug and terminates in a gunpowder capsule 19, the outer end of the fuze being covered by a patch 20 of match composition. A cardboard plug 21 secured by a paper patch 23 is blown out of the smoke outlet when gas pressure develops in the casing. On the plug 15 is a loose disc 24 with its underside attached to a tape 25 folded over the disc and attached to a striker 28 facing the disc, the tape and striker being held in place by a paper patch 29. The disc 24 is held in place by a paper disc 30 secured to the casing by a paper strip 31. A pull on the free end 32 of the tape 25 frees the disc 24, whereupon the striker can be used to ignite the match composition and hence the fuze and smoke composition.

Title: Means for driving machines from the engine shaft of motor vehicles
IPC: B60K25/00
Filed: 1929-01-04
Abstract: 303,746. Tavernier, F. X. R. Jan. 7, 1928, [Convention date]. Driving auxiliary apparatus and external machines. - Auxiliary machines. such as an air compressor, a water pump, a winch, machine tools &c., may be driven by means of a clutch device on the machine adapted to engage the starter end of the engine crank-shaft or the end of the starting-motor shaft, the ordinary clutch device on the engine or motor shaft being unaffected and no extra support for the shaft of the machine being required. The machine. may be mounted on the vehicle or on the ground, and may be driven through reducing or multiplying gearing and a flexible shaft. Where the engine shaft 1, Fig. 1, is provided with a cross-pin 2 for engagement by a detachable starting-handle, the shaft 3, Fig. 3, driving the auxiliary machine may be formed with a clutch end having notches 5, 6, 7, any one of which may be engaged with the pin 2 to suit the required position of the machine. In a modification, the shaft 3 is formed with a one-way clutch similar to that on the starting-handle but acting in the opposite direction so that the engine can drive the machine. In the construction shown in Fig. 7 the starting-motor shaft 14 carries a part 11 formed with slots or recesses 19 adapted to be engaged by projections on a member 17 coupled to the shaft of the machine to be driven. The coupling member 17 may be retained in place by a cap 15 screwed into a sleeve 10. The part 11 is formed with ratchet teeth for engagement by the starting-handle. The member 17 may have driving engagement with a nut on the end of the starting-motor shaft. The Specification as open to inspection under Sect. 91 (3) (a) states that where the engine shaft is formed with a one-way clutch part for engagement by a cross-pin on the starting-handle, an adapter is fitted to the engine shaft, this adapter having a cross-pin at its free end for engagement by the end of the machine shaft 3. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to artificial hands and the like
IPC: A61F2/58
Filed: 1922-01-05
Abstract: 195,751. McKay, P. M. Jan. 8, 1922. Limbs, artificial.-An artificial hand has two relatively movable opposed grippers with a ratchet mechanism for rapidly adjusting .the span, locking the grippers, and applying a final gripping pressure. A stationary gripper 14 is mounted on the bucket (not shown) and carries a rotatable sleeve 15 to which is pivoted a movable gripper 25. A ratchet 22 is fixed to the sleeve and co-operates with a spring pressed detent 23 hinged to a lever 33, which latter is pivoted on a pin 32 within the gripper. The lever 33 is controlled in one direction by a spring 37 and in the other bv a cord which controls the detent 23 and is actuated from body harness. In operation. if tension on the cord 38 is slightly relaxed, although the lever 33 and the detent are held to the right of the position shown, the gripper 25 will be moved by the spring 37 to close on an object. If the tension is wholly relaxed, the detent engages the ratchet, thus locking the gripper 25, and the lever 33 is moved anticlockwise about the pin 32 by the spring 37 to impart a final gripping pressure. The gripper 14 can have two fingers, or one only, or can have additional detachable fingers, and is connected to a notched tongue 6 pivoted in lugs 4, 5 and held locked by a spring latch 8. The lugs 4, 5 terminate in a grooved end 2, 3 engaging the bucket. The gripper 25, which constitutes the thumb, rotates round an axis lying lengthways of the hand and is locked in position by a spring pressed pin 28 engaging holes 26 in the gripper 14. Specifications 100,054, 109,412, and 120,302 are referred to.

Title: Improved arrangement for alternating current relays
IPC: H02H1/00
Filed: 1931-01-06
Abstract: 370,899. Protective cut-out arrangements and electromagnetic relays. STAGE, S. J., Malm÷, Sweden. Jan. 6, 1931, No. 458. Convention date, Jan. 7, 1930. [Class 38 (v).] Relays such as impedance and reverse current relays having a voltage and a currentresponsive element are arranged with a series resonant circuit connected in series with the voltage-responsive element, this circuit having a natural frequency substantially equal to that of the line to which the relay is connected so that during response to short-circuit conditions, which are accompanied by an excessive drop in line voltage the action of the resonant circuit causes a persistence of current in the voltage coil for a time sufficient to ensure the operation of the relay. As shown in the Figure, the voltage coil 3 fed from the voltage transformer 2 has in series an inductance 5 and condenser 6. Additionally an ohmic resistance 4 is included in the series circuit which is of the same order of magnitude as the wave resistance, i.e. the square root of the ratio of inductance to capacity of the circuit. Normally the effects of the inductance and capacity neutralize each other the current being determined by the ohmic resistance, the major portion of which consists of the resistance 4, but on a sudden collapse of the voltage across the line 1 the effect of the inductance and capacity cause an appreciable current to persist in the voltage coil circuit for some cycles, this current having an amplitude sufficiently great to ensure the operation of the relay. In modified arrangements, Figs. 3 and 4 (not shown), the resistance 4 may be connected across an inductance 5 and condenser 6, and an additional inductance or condenser may be connected in series with the main voltage coil circuit. The currentresponsive element 7 of the relay is fed directly from a current transformer 8 in the line 1.

Abstract: 331,557. Patent-Treuhand-Ges. fiir Elektrische Gl³hlampen, Wiegand, K., and Bratel, K. Jan. 7, 1929. Supplying consuming devices.-In systems for supplying luminous electric discharge tubes with alternating current of over 500 volts and of 15 to 100 periods per second, an inductive or ohmic impedance and a capacity are inserted in series in the main primary circuit of the supply transformer or in series in the main secondary circuit or one in the primary and one in the secondary circuit. On account of the charging and discharging of the condenser, reliable ignition of the tube is ensured in aerodromes and misty places or the voltage of the transformer may be reduced. If a stray-field transformer e, with coils side by side and relatively adjustable or separated by a metal sheet, is used, the inductance is dispensed with, the condenser c being at least 2 or 0.1 microfarads according as it is in the primary or secondary circuit and being several times larger than the capacity necessary for compensating for the phase-displacement due to the leakage of the transformer. In both forms, the condenser may be short-circuited after the tube has started. Specifications 210,053 and 239,826 are referred to.

Abstract: 830,541. High voltage switches; snap-action switches; switch cases; operating members for switches; arcing preventing in switches. S. & C. ELECTRIC CO. Jan. 7, 1957, No. 553/57. Class 38 (5). In a mechanism for opening under load a high voltage isolating device and comprising an auxiliary circuit interrupter similar to that of Specification 825,913, connection of one contact of the interrupter 27 to a fixed contact member 24 of the isolating device (not shown), is effected by a bow-shaped rockably-mounted member 29. The member 29 has trunnions 30, Fig. 7, mounted in arms 32 extending from the top cap 34 of the interrupter and has springs 35 normally biasing it to the full line position, Fig. 6. The connection of the other contact member of the interrupter to the moving contact member 19 of the isolating device is effected by a prong 40 which engages within the member 19. Undesired disengagement of the prong 40 is prevented by a keeper 49 which is pivoted at 50 on a shaft 51 and biased to the full line position by a spring plunger 58. The shaft 51 is biased to a central position by a spring 56 and in this position prevents the disengagement. By turning the whole mechanism, the prong 40 is rotated out of the member 19, this action being permitted by the keeper 49 and shaft 51 turning about the axis of the shaft 51. A spring 65 maintains adequate contact between the prong 40 and the member 19. The mechanism is also provided with a spring-biased latch 148 which engages the lower end of the outer housing 67 of the interrupter when the contacts 75, 120 have been opened and prevents the accidental reclosure of the interrupter when the mechanism is being removed from the isolating device. Specification 830,542 also is referred to.
