Title: Improvements in and relating to Electro-plating Apparatus.
Inventor: EVANS-JACKSON JOHN EDWARD
IPC: C25D17/20
Filed: 1917-09-20
Abstract: 119,091. Jackson, J. E. Evans-, (Pothoff, G. 7'.). Sept. 20, 1917. Barrel apparatus.-A plating barrel is rotated alternately in opposite directions, say, for several complete revolutions in each, without being moved in the direction of its axis. Current may be automatically switched off during the short intermediate periods of rest, and also when the drive is arrested manually. In a particular arrangement, the perforated barrel is mounted on a shaft supported in bearings on the end walls of a vat. Connexion between the articles and the shaft of the barrel is made by an endless chain. Anodes bung on rods at either side are curved so as nearly to meet beneath the barrel. One supporting rod extends the whole length of the vat, while the other terminates at a bracket a short distance from one end, the two rods being electrically connected. A switch blade sliding on the bracket into and out of contact with a contact 33 is carried by a hand-lever 36 pivoted on a bracket 37. The lever 36 embraces a flanged sleeve splined to a shaft and carrying a toothed driving wheel 42 which is thus moved into or out of engagement with a toothed wheel, preferably of non-conducting material, on the end of the barrel Actuated bv the same lever 36 is a fork 64 for shifting a driving belt between fast and loose pulleys 62 on a shaft 57. The lever 36 passes between collars set at such distance apart on the sliding carrier 63 of the fork that the circuit is broken at the switch 33 before the mechanism is stopped. On the pulley shaft 57 is a worm driving a worm wheel 56 on a shaft 48. Loose bevel pinions 46, 47 on this shaft gear with a bevel wheel 45 on the shaft of the barrel-driving wheel 42. A clutch member 52 splined to the shaft 48 between the bevel pinions is embraced by a lever 70 operated by a link 72 carrying rollers which bear on a cam 79 driven slowly by a worm on the shaft 48 and designed to give considerable dwell in the extreme positions of the link and lever. Connexion between the link and lever is made by a pin on the link confined between springs 104, 105 in a slot in the lever, to allow for incomplete initial engagement between the clutch teeth. On the lever 70 is a conductor 102 which in either extreme position bridges a pair of contacts 100, 101, to close circuit through the vat. Reference has been directed by the Comptroller to Specification 26849/04.

A pin drum of a circular machine is racked round by pawl and ratchet mechanism 4, 2 the ratchet being secured to the bottom of the pin drum 1. Spring-loaded plungers housed in the drum 1 exert sufficient force to cause a certain amount of frictional resistance to be created between the ratchet wheel 2 and the fixed support beneath the ratchet and supporting the drum whereby over-racking is avoided by this braking action. The ratchet wheel has at least one tooth 3 longer than the rest so that by modifying the oscillating action of the lever 6 the drum can be continuously operated, stopped after a certain amount of operation, or prevented from operating at all by lifting the pawl completely from engagement with the ratchet.

Title: Improvements in or relating to clamping circuits for electrical signal transmission systems

Filed: 1950-06-02
Abstract: 693,761. Television. WESTERN ELECTRIC CO., Inc. June 2, 1950 [June 4, 1949], No. 13841/50. Class 40 (iii). A clamping circuit arrangement for an electrical signal transmission system, such as a television system, in which the signals include recurrent reference level portions, comprises a preliminary damping circuit including a first clamping device driven by an amplifier for the signals and arranged to clamp the voltage level in the signal input to the amplifier, and at least one other clamping device also driven by said amplifier and arranged to clamp the voltage level at another point or points in the system external to the preliminary clamping circuit. In Fig. 2, television signal 72 including synchronizing pulses 70 is applied through condensers 3 and 110 to modulate the frequency generated by reflex klystrons 4 and 100. The input point 32 is also connected through condenser 2 to amplifier 8, the output of which feeds phase inverting stage 17 having equal anode and cathode loads. The balanced outputs A, B serve as clamping signals and are applied to twin diode 5 to clamp the input of the blanking amplifier to earth during each synchronizing pulse. The circuit comprising valves 5, 8 and 17 functions as described in Specification 669,455 as a preliminary clamping circuit and by virtue of its clamping action on the input signal to amplifier 8 is effective to eliminate low-frequency distention and drift in the clamping signals A and B. These signals are then applied to control the clamping at a plurality of different points throughout the system, each of which may be clamped to a different voltage level. As shown, twin diode 6 is controlled to clamp the repeller of klystron 4 to the potential set by potentiometer 27, and twin diode 104 is controlled to clamp the repeller of klystron 100 to a different potential set by potentiometers 124.

Abstract: 132,006. McAlpine, G. L. Aug. 28, 1918. Projectile fuses.-Relates to firing-mechanism for shells and the like of the kind described in Specification 127,654, and consists mainly in an arrangement whereby the firing-pin is held up by a transverse retaining-member independent of the action of the firing-spring and under the control of a separate spring which presses it against the soluble member. A further feature of the invention consists in providing means whereby the solvent is applied automatically to the soluble member on firing the shell from a gun, by the breaking of one or more solvent containers. In the fuse shown, the spring-pressed firing-pin B is held up by a slotted transverse bolt E, which is held by a spring e' against a disk C of celluloid or the equivalent. The mass of the bolt is so arranged that centrifugal action during flight partly or completely takes off the pressure of the bolt from the disk .C. An absorbent pad c is kept in contact with the disk C, the chamber D containing the pad communicating with chambers a', Fig. 2. containing bottles F filled with acetone or other solvent. When the shell is discharged, lead masses f set back against the bottles and break them, liberating the solvent, which passes into the chamber D, where it acts upon the disk C, ultimately softening it so as to free the bolt E. Movement of the bolt by its spring e<2> brings an aperture therein into line with the firing-pin B, which is thereupon actuated by its spring b. A removable safety-pin for the bolt E may be provided.
