Title: Facsimile Marking Circuit.
IPC: H04N1/40
Filed: 1968-07-26
Abstract: 1,191,559. Facsimile apparatus; transistor amplifiers. STEWART-WARNER CORP. 26 July, 1968 [28 July, 1967], No. 35832/68. Headings H3T and H4F. In a facsimile recorder, in which a pair of electrodes electrolytically mark a recording medium, an input signal is applied to a bridge circuit which is connected to means for controlling the current through the recording electrodes in accordance with any unbalance of the bridge, and means responsive to variations in the electrode current are provided to adjust the bridge towards the balanced condition. As shown, the recorder is designed to operate with a data transmission system employed with conventional telephone lines, the data output being applied to input 20 and comprising voltages positive relative to the ground line 22. The input is applied to an emitter follower transistor 12 which together with the 12-volt positive power supply and emitter resistor 30 forms a first arm of a bridge circuit. The other arms of the bridge comprise resistors 32 and 34, resistor 40, and resistors 42 and 44. A differential amplifier 50 comprising two transistors 54 and 56 is connected to the bridge junctions 46 and 48 and its output is applied to a darling- ton-pair amplifier comprising 2 transistors 76 and 84 which control the current supplied to a movable electrode 86 which marks an electrolytic recording medium placed on a fixed electrode 88 which is grounded. The bulk of the electrode current flows through emitter resistor 44 which also forms part of one arm of the bridge so that when the input signal increases the voltage at bridge junction 46 increases, the recording electrode current increases and the voltage at bridge junction 48 increases thus providing negative feedback which tends to rebalance the bridge.

Abstract: 963,013. Making gearing; welding by pressure ; jointing by forging. BORGWARNER CORPORATION. Oct. 20, 1960, No. 36068/60. Headings B3A, B3H and B3R. In uniting two metal blanks to be telescopically disposed with respect to each other, a bore is formed parallel to the axis, or axially, through the first blank, the second blank is inserted in the bore and is heated in the regions adjacent to and between the ends of the first blank until it becomes plastic in these regions which are remote from the ends of the second blank and the second blank is compressed axially to effect radial expansion of the plastic regions to contact the bore in the first blanks and to form a driving connection therewith, without causing radial expansion of the second blank between the regions and the ends of the second blank. In making a gear blank for a gear pump an axially drilled blank 10 cut from round bar is clamped between two members 27, 28 carried on relatively movable members 16, 17 and a shaft 13 fitting with clearance in the axial bore is supported on two cooled hollow electrodes 18, 19 carried on the members 16, 17 and is clamped by pneumatically urged cooled hollow electrodes 33, 34. Current is passed between the electrodes to heat the shaft by electric resistance heating and when plastic pneumatic or hydraulic rams 37, 38 carried by the members 16, 17 compress the shaft axially. The shaft expands radially and when it contacts the bore current is short-circuited to heat the blank 10, the shaft then fusing to the blank for a short distance inwardly of each end of the bore. Gear teeth are subsequently provided on the blank. The blank 10 may be provided with a semicircular or other section peripheral groove 39, Fig. 4, into which the plastic metal flows but is not fused. The groove may be formed in the shaft or in both blank and shaft. The peripheral edges of the groove where fusing takes place may be bevelled at 60, Fig. 11, and the groove may be omitted and the edges provided with arcuate or right-angled recesses. A semi-circular groove 63, Fig. 10, may be provided near one end of the bore and a rectangular groove 64 at the other. Instead of using cooled electrodes separate cooling of the shaft may be used, the bore need not be axial or of the same section as the shaft and other electrical or other heating may be employed.

Title: Improvements in the production of composite mobile fuels
IPC: C10L1/32
Filed: 1920-12-29
Abstract: 160,754. Bates, L. W. March 23, 1920, [Convention date]. Liquid fuel.-In the preparation of a mobile fuel consisting of up to 65 per cent of coal dust or other carbonaceous particles more or less stabilized in liquid hydrocarbon, the coal is freed from ash and other impurities by froth flotation. With the apparatus shown, coal from a pipe 2, 1-5 per cent flotation and peptizing oil from a pipe 3, and small amounts of other liquids such as soap, alkali, and oil from a pipe 4 are conveyed to the steam-jacketed pulverizing mill 1, and the product passed by the pipe 5 to a jacketed vessel 6 in which it is agitated with about 10 volumes of water from pipe 10 while air or other gas from a pipe 8 is forced through the canvas base 7. The froth is led by a baffle 12 to a spitzkasten S, overflows to a launder 26, and on the shoot 15 is broken by a stream of oil from a pipe 16 and dried by heating the jacket J to above 100‹ C. The purified coal with peptizer and lime-resin soap or other stabilizer is then agitated in the jacketed vessel 18 with liquid hydrocarbon from the pipe 32, the complete fuel being removed by the pipe 19. A centrifuge may be inserted to remove excess of oil from the coal mixture issuing from the mill 1, the finished fuel may be centrifuged, the liquids removed being used as fuel for internalcombustion engines. The coal should be pulverized until about 85 per cent passes through a screen of 200 meshes per linear inch, and the treatment is preferably effected at 65-95‹ C. If further reduction of the coal is required a second pulverizing mill may replace the mixer 18, and if all the oil has been added before dehydration on the shoot 15 further coal or a mixture of coal and oil may be added in the mixing vessel 18. The viscosity of the oil may be increased or decreased in the mill or the mixer, the coal may be given a preliminary washing, electrolytic, or flotation treatment to remove pyrities or other sulphides, ash, or other impurity, the sulphur content of the coal or/and oil may be reduced by electrolytic or/and chemical means, and the flotation water may be rendered acid or alkaline, further alkali being added to the de-ashed mixture if necessary to counteract acidity and to assist stabilization. The stabilizers specified are products of the steam or destructive distillation of coal, peat, or lignite, water-gas tar, coal tar. solvent naphtha tar, creosote, pyridine, alkali, calcium resinate or other soap, and ozone or other gas having peptizing qualities. Specifications 149,306 and 154,605 are referred to.

Abstract: 1,081,429. Cameras and cassettes therefor. AGFA A.G. Sept. 4, 1964 [Dec. 20, 1963], No.36384/64. Heading G2A. A film cassette has on its exterior a feature having two abutment surfaces, one of which serves to locate the cassette accurately in the camera, and the other being indicative of the film sensitivity and controlling a corresponding sensing device accordingly in the camera. As shown, the cassette 3 has a flattened part 28, on which is located a T-shaped member 9 (see also Fig. 4 not shown). The cassette is inserted in the direction of arrow a into the camera, where it is held by a clip 6, 8. The shoulders of the member 9 locate against the ends of two projecting parts of the clip, such as 8a, so providing accurate positioning of the cassette. The leg of the T-member 9 engages against a lug 12a of a resilient tongue 10a stamped out of the clip 6, 8. Two contacts 11, 14 are shown (there may be more), each being connected through a separate fixed resistance to a galvanometer. As shown in Fig. 2, the tongue 10a is lying against contact 11. If the leg of member 9 does not project very far, then it does not move lug 12a to any great extent when the cassette is inserted. However, if it does project sufficiently far, lug 12a is pushed far enough for tongue 10a to leave contact 11 and engage contact 14, thus bringing a different resistance into the galvanometer circuit. The galvanometer is rotatable as a whole, and can also be set manually according to exposure conditions.

Title: Improvements in or relating to negative impedance circuits
IPC: H04B3/18
Filed: 1962-09-27
Abstract: 958,175. Negative Impedance repeaters; equalization. WESTERN ELECTRIC CO. Inc. Sept. 27, 1962 [Sept. 29, 1961], No. 36676/62. Headings H3T and H4R. A negative impedance device is arranged to be in shunt across the line towards one end of a range of frequencies and in series towards the other end of the range. The invention is applied to the use of a short circuit stable negative impedance converter to effect equalization as well as amplification in an unloaded line. Such converters operate more effectively in shunt than in series. Accordingly the negative impedance converter is coupled to the line through one winding 17 of a three winding transformer, the other windings being split and connected by a common condenser 18. At high frequencies condenser 18 presents low impedance and the negative impedance circuit is thus coupled in shunt across the line to give high gain. At low frequencies condenser 18 presents high impedance and the converter is thus coupled in series with the line. The negative impedance converter comprises a pair of circuits of the type described in Specification 737,506 cross-coupled between collector and base via condenser inductance combinations 41, 42; 43, 44 to give positive feedback. The converter provides a negative version of the terminating impedance comprising condenser 20 and resistance 19 which are chosen to match the line impedance. Inductance 48 balances out the leakage inductance of transformer 14. Inductances 42, 44 are arranged on a common core to provide mutual as well as self inductance. The turns ratio 1: N of coils 15, 16 may be chosen for impedance matching between the central office equipment and the non-loaded line.
