Title: Machine tools for machining internal surfaces of hollow cylindrical components
Inventor: TAIT WILLIAM HENRY
IPC: B23B41/12
Filed: 1956-03-23
Abstract: 822,031. Centre-less boring machines. GLACIER METAL CO. Ltd. March 15, 1957 [March 23, 1956], No. 9185/56. Class 83 (3). A machine for boring the internal surface of hollow cylindrical components comprises three rollers supporting the outside of the component, one at least of the rollers being driven, means for supporting a non- rotary cutting tool and a rotary abutment disposed at the upper end of the component, remote from that at which the tool enters, for closing the end to prevent swarf escaping therefrom. The driving roller 19, Fig. 1, arranged to operate opposite the cutting tool 40, is mounted on a transverse slide inclined to the horizontal and moved by an hydraulic ram 30. An electric motor 14 drives the roller 19 through shafting and universal joints 15, 16, 17 finally through V- belts 21. Adjustable idle rollers 23, Figs. 3 and 4, are provided opposite drive roller 19 and are provided with a shoulder 49 which retains the component 24 against axial movement. The freely rotatable abutment 50, Fig. 4, which closes the opposite end of the component prevents axial movement upwardly. The abutment is carried by a bracket 52 and is fed automatically into position for a working operation. The tool 40 is carried on a lever 41 oscillatable towards and away from the work centre-line by means 43. During operation, which may be automatic with limit switches to control the succession of movements, the work is placed on the shoulders of the idler rollers, the roller 19 is moved up to engage and drive the work, the closing abutment is fed down and an hydraulic piston 48 feeds the tool through the work. An abutment 65, Fig. 3, pushes the component off the shoulders of the idler rollers into a receptacle at the base of the machine after a working operation.

Title: Improvements in and relating to liquid dispensing apparatus
IPC: B67D7/76
Filed: 1941-07-24
Abstract: 551,582. Reciprocating pumps. GILBERT & BARKER MANUFACTURING CO. July 24, 1941, No. 9410. Convention date, July 24, 1940. [Class 102 (i)] [Also in Groups XVIII and XXIX] In apparatus for dispensing measured quantities of oil &c. the oil and any air present are raised from the storage tank 13, Fig. 4, to an air-liquid separator vessel 18, by a variable capacity rotary pump 65, and that liquid is measured and delivered through pipe 30, sight glass 32 and hose 31 by a reciprocating piston pump 21, which is driven from the shaft of the rotary pump through a hydraulic clutch 25, worm gear 87 and shaft 28. The register 29 is also driven from the shaft 28. The separator vessel is fitted with a removable strainer 19 and provided with a baffle 18 over which the oil flows to a passage 117 communicating with chambers at the ends of the measuring pump cylinder. The rotary pump is of the radial sliding vane type and discharges air through a passage 37, to a chamber 38 fitted with a piston and cylinder device for adjusting the eccentricity of the pump casing according to the delivery pressure. The clutch comprises a vaned rotor 78 on the shaft of the pump 65 and a bucket wheel 79 on the shaft of the worm gear. Torque is transmitted by the clutch only when the pump chamber 53 contains liquid, which enters the vaned rotor of the clutch through a pair of triangular centre ports 80 controlled by valve plates 81 adjusted by centrifugal force opposed by a spring connecting the valve plates. The measuring pump comprises pistons 94, Fig. 8, fitted with rollers 100 engaged by cams 104 on the shaft 28, and inlet and discharge lift valves 109, 110, Fig. 3 are arranged in chambers at the ends of the cylinders. Air and vapour discharged through the chamber 38 passes by a conduit 41, Fig. 4, to a further separator 42 fitted with a float valve for returning liquid back to the tank 13.
Patent GB-622866-A (GB)
Title: Stabilised oscillator
IPC: H03L5/00
Filed: 1947-04-09
Abstract: 622,866. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd. April 9, 1947, No. 9410. Convention date, Feb. 21, 1944. [Class 40 (vi)] In an oscillator, the amplitude of the output voltage is stabilized by means of a parallel resonant circuit forming an anode load for the valve and consisting of an inductance with a magnetized core shunted by a condenser, the resonant frequency of the parallel circuit being slightly below that of the oscillator. As shown in Fig. 1, the stabilization is obtained by using a permalloy dust coil as part of the tank circuit L, C, which is premagnetized by the plate current of the oscillator tube. In this way the inductance of the coil increases when the alternating voltage across it increases and vice versa, so that by adjusting the resonant frequency of the tank circuit to be slightly below the oscillator frequency, very slight variations of the coil impedance produce relatively large variations of the plate load impedance, thus stabilizing the oscillator output. This effect may be increased by the application of series negative feedback. The oscillator output can be varied without upsetting the stabilization, by varying a trimmer #C, and correction for temperature variation may be effected by using a trimming condenser with the appropriate temperature characteristic. The oscillator may form part of a harmonic generator.

Title: Method coder and decoder for the transmission and compatible reception of standardized television signals
Inventor: KEESEN HEINZ-WERNER
IPC: H04N7/00
Filed: 1996-06-27
Abstract: In a system for generating a compatible television signal with a "letterbox" display format, groups of vertically arranged picture elements (pels) are subjected to vertical DCT transformation producing eight DCT coefficients. Intermediate sixth and seventh coefficients are placed in the letterbox bar regions. The remaining six coefficients, namely the first through fifth coefficients and the highest frequency eighth coefficient, are inverse DCT transformed and processed with the main image information. A standard aspect ratio receiver displays a letterbox image using only the remaining six coefficients. A wide aspect ratio receiver uses the six remaining coefficients with the two coefficients from the bar regions, after inverse DCT, to produce a full resolution wide aspect ratio image.

Abstract: - Button cells and lead-acid batteries are separated from the scrap which is then mechanically reduced and then sieved and pieces above 5 mm are passed under magnetic separators and the part not removed is processed through magnetic drum-separators . Each time the magnetic parts are moved down one route , the part which passes the sieve after breaking up go down another path and the parts which pass as non-magnetic small pieces go via a third. The scrap which emerges as large non-magnetic pieces after the second treatment is also treated separately. - The material passing the sieves is treated to remove alkali and ammonium-salts, filtered and washed and dried. It is then, with the material from the 3rd path in a rotating oven at 500-900 deg.C, in an oxidising ambient, with the exhaust gases being burnt off (30), dust sepd at 357 deg.C and Hg condensed by cooling. The material is pelleted or granulated and, after adding coke and pref. CaO to give a ratio of CaO+MgO/SiO2 = 1.3-3, heated in reducing gas at 1000-1250 deg.C, sepg. Zn and Hg . The residue is cooled in an inert gas, sieved, reduced mechanically to a size of less than 0.3 mm and passed through a magnetic separator. Non-magnetic material is then dissolved in a neutral or weakly acidic soln. and the mixture filtered. The remaining MnO2 is then dissolved in H2SO4 and separated from C,CaSO4 and SiO2. - The material in 2nd path is subjected to cutting , passed through another mechanical reducing mill and heated to 315 deg.C max. temp.. It is then ground , sieved or mechanically separated and the fine part joins the other material passing a sieving stage. The magnetic material is heated in a rotating oven at 500-900 deg.C, pref. 700 deg.C, separating Hg and Zn from the bulk.
