Title: Improvements in or relating to regulating valves for refrigerating installations
IPC: F25B41/06
Filed: 1950-01-24
Abstract: 686,462. Refrigerating. JOERGENSEN, H. J. Jan. 24, 1950 [Feb. 2, 1949], No. 1845/50. Class 29 [Also in Group XXIX] In a compression refrigerating system the supply of refrigerant, e.g. methyl chloride, from the water-cooled condenser, Fig. 1, to the evaporator coil 4 is regulated by a valve 10 having an inlet 15, Fig. 2, and an outlet 13, and a closure member 36 seating on the inlet and carried by a crosspiece 35 secured by bolts 31, 32 to a plate 17 on the movable end of a bellows 19. The other end of the bellows is fixed to the housing through a distance piece 20. The closure member is controlled by the vapour pressure on the bellows. An adjustable spring 25 urges the member to its seat, and the bellows may be filled with a gas at a slightly higher pressure than the maximum in the housing. Thus, the spring 25 may be a weak spring to increase the sensitivity of the valve.

Title: Improvements in or relating to telephone pay stations
IPC: H04M17/02
Filed: 1930-01-23
Abstract: 355,168. Coin-freed telephone apparatus. TELEPHON-APPARAT-FABRIK E. ZWIETUSCH & CO., GES., 6, Salzufer, Charlottenburg, Berlin. Jan. 23,1931, No. 2306. Convention date, March 14, 1930. [Class 27.] Coin action, weight.-At an automatic telephone pay-station, the outgoing conversational circuits are disabled by a magnet which is operated over off-normal dial springs, locked to line, and released by insertion of coin. The equipment comprises a coin box, including the magnet, adapted to form a pay-station when connected to a standard telephone set with minimum alteration of the internal connections of the set. In the circuit diagram, Fig. 3, the circuits above the dot- and-dash line represent the telephone set, normal connections marked x being removed and the broken line connection added. When the receiver is lifted and the dial moved off-normal, magnet R operates over a, impulse springs n s i, off-normal springs n s a, R, b, and locks over r, switch-hook HU, n s i. A member 6, Figs. 1 and 2, on the armature is moved to block the lower end of the coin shoot 2, and circuits for the transmitter M and transformer J are completed over a high-series resistance Wi3 so that speech currents due to use of the transmitter or the receiver (as a transmitter) are shunted by low-resistance magnet R. The resistances of the various circuits are however such that the reply of the called party is audible. The coin now inserted rests against 6 and closes springs m, k to short-circuit the magnet which conditions the circuits for conversation and permits the coin to drop into box 8. Fraud, preventing.-To prevent fraudulent operation of the coin-actuated springs m, k, a guard comprising fixed and pivoted plates 10, 12 is mounted beneath the coin-aperture 9. If a wire is inserted, it engages the lower end of 12 which is thereby swung over so that the wire is gripped between the upper ends of 10, 12.

Title: Method and machine for making paper
IPC: D21F9/04

Abstract: 592,014. Fourdrinier paper-making machines. SCOTT PAPER CO. Feb. 1, 1045, No. 2516. Convention date, Feb. 1, 1944. [Class 96] Paper pulp is fed through a passage 3 to a zone 4 of the wire-cloth 1 of a paper-marking machine where it is supported on the breast roll 2 and subjected to suction between spring- pressed seals 14, 24. The suction, with or without hydrostatic pressure on the pulp, draws most of the free water into peripheral cells 5 of the breast roll, in Which it is retained under supplementary suction from a compartment 24, 25, which is regulated by a valve 28. The Water is then flung off by centrifugal force into a conventional save-all pan. The suction-box casing 11 may be adjusted about the axis of the breast roll 1 by worm gearing. A shaft 12, carrying by a structure 19, the supplementary suction compartment, may also be adjusted about the axis of the breast roll 1, a surface 17 of the box supporting curved flange 18 of the structure 19. The upper surface of the pulpfeed passage 3 is articulated as illustrated to facilitate vertical adjustment of its several parts, which is effected by worm and screw gearing, as illustrated, longitudinal adjustment being also provided. The pulp may be fed at the speed of the wire-cloth to provide turbulent flow and random deposition of the fibres, or at less speed than the wire-cloth to produce a directionally-felted effect. The pulp feed may be through a motor-controlled valve, and the flow indicated by a venturi meter. The speed of the wire-cloth may be indicated by a tachometer, and an indicator for the depth of the feed passage 3 at the forming zone may be provided.

Title: Improvements in or relating to the measurement of fuel consumption and efficiency
IPC: G01F9/02
Filed: 1953-01-29
Abstract: 745,378. Electric indicating systems. HUTCHINS, D. C., and BURTON, P. Jan. 20, 1954 [Jan. 29, 1953], No. 2523/53. Class 40(1) The fuel consumption of. an engine driven vehicle is measured by applying an e.m.f. proportional to engine speed and derived from a tachogenerator 9, Fig. III, to a resistance 6 the tapping 7 on which is varied manually or automatically in accordance with fuel consumption per unit time so that the current flow measured at 10 is a measure of displacement e.g. miles per gallon. Inverse reading in e.g. gallons/mile may be obtained by electrically dividing the fuel consumption by the speed. Preferably the current from the generator flows through a constant resistance network, Fig. IV, formed by the portion X of resistor 6 and a portion of a further resistor 11 tapped off at 7. For measuring efficiency, i.e. work/gallon, Fig. V a current proportional to speed is fed to a constant resistance primary network Y-12-14, at R and subdivided at moving contact 12, operated e.g. by a hydraulic dynamometer, in accordance with the torque transmitted, so that a current proportional to power passes through meter 15 and a secondary constant resistance network 6-7-10-11 similar to that of Fig. IV. The current through meter 10 is then proportional to the work done/ gallon and the meter may be calibrated as an efficiency meter. The current through meter 15 may be proportional to the nth power of the B.H.P. of the engine, according to the type of dynamometer used, in which case the resistance 6 must be varied according to the same power of the fuel consumption.

Title: Improvements in or relating to the cooking of drying oils and/or varnishes
Filed: 1935-01-26
Abstract: In cooking drying oils and varnishes for the paint industry at atmospheric pressure and at about 290--300 DEG  C. in large kettles containing over a ton of oil, a current of inert gas is passed through the oil at a rate of about 50 cub. ft. or more per minute throughout the greater part of the cooking period, the gases and vapours are passed into a separate condenser where the volatile matters are removed, and the stripped gas is passed to the atmosphere or is recirculated.  The current of gas removes substantially all undesired volatile matters from the oil in 1 to 2 hours.  The gas may be mainly nitrogen, carbon dioxide and carbon monoxide, or any mixture of these produced by passing air through red-hot coke, anthracite or like fuel and cleaning and cooling the products.  The gas may be introduced through perforations in a stirrer.  The kettle may be provided with a chamber with or without baffles in which oil or varnish in the froth is separated from the gas.  The top of the kettle may communicate with the atmosphere by a small pipe.  When inert gas is circulated through the system, a small amount may be continuously introduced under pressure to prevent inflow of air.

One or both of the handle members a, b are slotted at g to receive a pivot-pin e which supports a spring normally holding the members apart, or any other form of sliding connection may be employed. The cutting-edges of the blades c, d, are turned over at right angles and are rounded off as at n to form scrapers for the bottom of the bowl. In a modification, the blades c, d are pivoted about their centres to upwardly projecting ribs on the handles a, b and are held in position by springs on the pivots bearing against projections on the sides of the blades opposite to the cutting edges. Other tools, such as a hammer p and a cigar cutter o, may be combined with the scraper. One of the Provisional Specifications also describes the blades as being flexiblly mounted on the ribs or fexibly or pivotally mounted on, and connected in a variety of ways to, the pivoted arms.
