Title: Improvements in furnace electrode regulators
IPC: H05B7/156
Filed: 1944-04-17
Abstract: 605,313. Fluid-pressure servomotor-control systems. DELAWARE ENGINEERING CORPORATION. April 17, 1944, No. 19879/47. Convention date, Aug. 12, 1943. Divided out of 599,848. Drawings to Specification. [Class 135] [Also in Group .XXXV] The movement of an electrode in an electric arc furnace is controlled by a hydraulic servomotor system comprising a piston and cylinder and associated control valve, the latter being inserted between the cylinder and a tank at high pressure for raising the electrode &c. and a tank at a low pressure not quite sufficient to counterbalance the electrode &c., and the flow of liquid from the high pressure tank to the cylinder and from the cylinder to the low pressure tank is controlled by the current flowing in the electrode circuit, whilst the flow of liquid from the low pressure tank to the high pressure tank is controlled by the level of the liquid in the low pressure tank. The invention is described with reference to the disclosure in Fig. 1 (Cancelled) of Specification 599,848.

Title: Improvements in pipe bending machines
IPC: B21D9/07
Filed: 1935-07-12
Abstract: 457,054. Angular bending. HAYWARD, T. A., Possil Engine Works, Glasgow. July 12, 1935, No. 19925. [Class 83 (iv)] In a pipe bending machine a sweep arm forms an initial bend and subsequently forms an offset abutment for further bending. The pipe 3 is fed between guides 12, 13. The guide 13 is then moved axially by hydraulic means to swing a sweep arm 2 and to slide a lever 1 through a pivoted bearing 7. A cam face 16 on the lever 1 engages an abutment 17 causing it to rock about a pivot 8 to effect the initial bend. The member 2 is then in position for subsequent bending as the tube is fed axially. The member 2 may be replaced by a roller.

Title: A process for the decolourization of shellac, or other lac resins
IPC: C09F1/00
Filed: 1928-07-13
Abstract: 316,423. Dutt, E. July 13, 1928. Resins.-Shellac and like lac resins are decolorized by treating a neutral solution of them in a volatile solvent, such as ethyl or methyl alcohol, with a calcined aluminous earth containing little silica or iron oxide, but containing a high percentage of titanium oxide, e.g. Indian Bauxite. The shellac &c. is preferably pulverized and washed in warm water to remove red colouring matter, and an alcoholic solution prepared containing 10-15 per cent of soluble lac substance. The solution is filtered to remove lac wax, wood debris &c. and neutralised by the addition of a base such as ammonia, amines such as methylamine or ethylamine, or oxides of calcium, barium or strontium. The calcined aluminous earth is added, the whole agitated for several hours and filtered, If an alkaline earth oxide neutraliser has been used carbon dioxide may be passed in and the solution refiltered to remove such compounds as carbonates. The solution may be concentrated for use as a varnish, or reduced to a viscous mass which may be formed into sheets on heated cylinders. The lac may also be precipitated in a form resembling " bleached " or White Lac by adding water to the decolorized alcoholic solution.

Abstract: 1,219,937. Remote control of radio receivers; semi-conductor circuits; colour television. MOTOROLA Inc. 1 May, 1968 [7 June, 1967], No. 20705/68. Headings H3Q, H3T and H4F. In or for a colour television receiver, a remote control unit comprises at least one tuned circuit 19 feeding a rectifier 35 the output of which is used to charge a capacitor 40 via a voltage threshold device 39. As described, a remote control device (not shown) provides a selection of four frequencies which are transmitted by line, radio or sound to an auxiliary receiver 10 . . . 14 in a colour television receiver. When signals having the frequency of tuned circuit 19 are utilized, they are rectified at 35 and break down a neon tube 39, charging a capacitor 40. The voltage across the capacitor is passed via a field-effect transistor to a transistor (not shown) which controls the phase of a reference signal so as to provide remote adjustment of hue. Remote control of hue in the other direction is achieved by sending signals having the frequency of tuned circuit 20 which are rectified at 48 with opposite polarity and break down neon tube 39 so as to discharge capacitor 40. A further circuit 17 feeds a varicap diode (Fig. 4, not shown) which adjusts the chroma by variation of tuning of a resonant circuit. Capacitor 40 and field effect transistor 42 should be very high resistance devices so as to retain charge for a period greater than 10<SP>6</SP> sees. so that the adjustment may be retained whilst the receiver is being delivered to a customer. Diodes 54, 55 protect the circuit against excessive input voltages.

[Also in Group XXXI] A tracked vehicle has each track driven through a separate clutch 15 driven by a common shaft 13 and each track is under the control of a separate band brake controlled by a fluid-pressure cylinder having limited freedom of movement with the band and brake drum until arrested by a stop to provide a servo effect for brake operation. Pressure pads 36 on a lined band 35 are forced together for brake application by a spring 44, Figs. 2, 3, acting on a piston 50 connected via rod 49, block 40, to one pad 36 and on a plate 42 abutting a block 40 and the other pad 36. The pad rotates with the drum until a shoulder 77 on the pad engages a pin 71 which then acts as an anchor. Four pins 71 in slots in blocks 40 support the brake on two parallel flanges 74, Fig. 1, constituting part of the vehicle frame. The brake is released by compressed-air acting on diaphragm 54, Fig. 3, to compress spring 44, a spring 60 aiding brake release. The ends of the two-part band opposite to pads 36 are connected by a nut and bolt 80, Fig. 2, to take up wear of the band.
