[Also in Division H4] A device for producing a train of pulses comprises logic circuits and a chain of storage units, e.g. a shift register, which are fed by control pulses, the polarity of each pulse of the train being dependent upon the polarities of a plurality of the control pulses previously supplied, and also comprises a feed-back arrangement connecting at least one storage unit to a logic circuit disposed either at the input of the chain or between two storage units. The Specification describes various forms of the disposition of the feed-back loop. The feedback arrangement may itself comprise triggers, storage units and logic circuits. Preferably the feed-back arrangement is such that some of the pulses fed to it are reversed in polarity or are suppressed; this has the effect that an error occurring in the control pulses affects only some of the pulses of the output pulse train, rather than affecting all the output pulses. In another embodiment the outputs of the storage units are connected to the inputs of storage units forming a second storage chain which also has a feed-back loop, Fig. 10 (not shown).

Abstract: 556,640. Automatic control systems. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and PETER, L. H. March 11, 1942, No. 3182. [Class 38 (iv)] [Also in Group XXXVII] In order to give warning of underload or overload conditions in, and/or cut off the supply to, electrode position apparatus of the kind employing static contact rectifiers, a current relay in series with an adjustable (current-setting) resistance is connected across an ammeter shunt or other resistance in the operating circuit. The shunt 5 of the ammeter A is shunted also by an adjustable resistance W in series with a relay R responsive to the current' in the plating-vat supply 1, 2 so that when the current gets excessive the relay R closes contacts R<SP>1</SP>, R' adapted respectively, to energize a red warning lamp D, whereby the operator is warned to reduce the operating current, and a remote indicating circuit 17. The lamp D and a green pilot lamp S are connected to the A.C. supply 13 for the rectifier, and a voltmeter V is connected across 1, 2, a reset switch RS is provided for relay R. Also connected across the shunt is a relay CR with normally-closed contacts CR1 in series with the holding-coil 24 of a contactor C controlling the supply to the transformers energizing the rectifiers, whereby, on overload, the supply in question is cut off. The relay R and resistance W may be employed alone as a warning device, Fig. 1 (not shown), or the relay CR and series resistance W may be employed alone as a cut-off device, Fig. 2 (not shown). Where, as in the case of anodizing aluminium, the current diminishes with time, the relays are adapted to operate as underload relays and the operator then increases the supply-voltage. The Provisional Specification refers to stand-by batteries for continuing the plating operation if the A.C. supply is cut off, and states that the relays may be used for automatic current-adjustment.

[Class 132 (ii).] The socket 2 of the head 1 of a golf club is filled with soft metal by casting and the soft metal is then drilled to form a cylindrical bore 5 at the bottom of which is placed a spherical, conical or pyramidal shaped member 8 and into which the slightly tapered end of the hollow shaft 6 slit at 7 is fitted. The slit end is forced against the member 8 so that prongs 9 are formed from the slit end which penetrate into the soft metal. The neck of the socket is then forced at 10 into conical form to displace the soft metal at that point and bring the neck of the socket 10 into close contact with the shaft 6. By the above means a connection is obtained which is axially indisplaceable, but vet somewhat resilient by reason of the soft metal used, and which however is very rigid at the end of the socket.
