Spray carburettors.-In a carburettor having a throttle piston b subject to engine suction through two or more lateral ports c, c' communicating through a semi-circular passage f with the induction port e, the binding of the piston against the wall of the enclosing-chamber is prevented by providing the piston with longitudinal grooves b<1> open at the top, and on each side of the ports c, c<1>. Air admitted through the grooves relieves the parts of the piston lying between them, and in contact with the wall of the chamber, of suction. The piston b may be controlled by a bell-crank lever h, either independently of, or conjointly with, a known fuel-regulating device. Specification 159,439 is referred to.

Title: Improvements in and relating to the manufacture of unstainable irons and steels
IPC: C21C5/28
Filed: 1922-03-01
Abstract: 198,633. Wild, R., and Wild, A. H. March 1, 1922. Alloys.-Iron-chromium alloys of the unstainable type are made by fusing in a molten iron or steel bath a ferro-chrome containing silicon, and submitting the product to an oxidizing blow. The bath may be one containing oxygen or oxides, for example recently-blown Bessemer metal, and the ferro-chrome may be prepared by reducing a chromium compound in the presence of iron by means of a low-carbon silicon-containing reducing- agent. The preparation of the ferro-chrome and its mixture with the bath may be effected simultaneously by performing the reduction of a chromium compound such as chromite within the bath itself. The reducing-agent used is preferably ferro silicon. Any necessary addition of carbon may be introduced at any suitable stage, and a deoxidizer such as a small proportion of manganese may be added prior to tapping or to blowing. Specification 197,733 is referred to.

Title: Improvements relating to the manufacture of margarine and cooking fats
IPC: A23D7/02
Filed: 1941-07-31
Abstract: 552,988. Margarine; cooking fats. CO-OPERATIVE WHOLESALE SOCIETY, Ltd., and GREEN, J. E. July 31, 1941, No. 9733. [Class 84] [Also in Group II] Margarine and cooking fats, consisting of solidified emulsions of solid fats and liquid oils with milk or water or both, are made by bringing the constituents together one by one or in any other sequence and emulsifying them by mechanical working whilst the fats are in a non-liquid condition. Homogenisation of the emulsified materials may be effected by further working. The process is preferably carried out in a vacuum mixing machine comprising parallel inter-geared spindles fitted with blades, the blades of one passing between the blades of the other, a variable speed gearing and revolving doctor blades. The vessel is jacketted for steam or water which can be thermostatically controlled to soften the fats without melting them and to facilitate cleaning. In an example, hardened whale oil and hardened ground nut oil are worked at a slow rate into a plastic condition whilst water and milk are added. Then lower melting-point fats e.g. coconut, palm kernel and palm oils are added and the speed increased and, finally, liquid ground nut oil is added and the speed further increased under reduced pressure. Salt may be dissolved in the water, colouring matter added to the oil and flavourings and vitamin-concentrates added to the mixture towards the end of the operation. When the fats come from the refinery melted, they may be mixed and allowed to set before treatment. The product may be delivered directly into paper bags or other containers.

Abstract: 706,785. Substation circuits. STANDARD TELEPHONES & CABLES, Ltd. April 18, 1952 [April 26, 1951], No. 9767/51. Class 40 (4) To compensate for variations in line impedance the receiver is shunted by a non-linear resistance element Z whose resistance is controlled by the unidirectional transmitterenergizing current received over the line. As shown, the greater part of this current traverses a fixed low-resistance element R, and the potential developed across R controls the resistance of Z. The receiver is isolated from D.C. by means of a transformer, Fig. 5, or a balanced bridge arrangement, Fig. 8. As shown, the invention is applied to anti-sidetone circuits having balancing networks X, but it may also be applied to side-tone circuits. Specification 706,784 is referred to.

Abstract: 1,214,877. Casting pipes. MONIER RESEARCH & DEVELOPMENT PTY. Ltd. 29 Feb., 1968 [7 March, 1967], No. 9971/68. Heading B5A. [Also in Division C1] Pipe is tamped from a mix of basic igneous rock, clay and water by a packer head apparatus consisting of a cylindrical mould having internally associated therewith a packer head with depending skirt which is capable of rotating as a unit relative to the cylindrical mould, while being moved upwardly at a controlled rate of travel directly above the pipe which is being progressively formed from a pipe mix fed from above into the annular space between the said skirt and the cylinder. The lower face of the peripheral portion of the packer head plate is provided with a series of circumferentially spaced ramps or "thread" starts which tamp the upper face of pipe mix fed past the packer head into that portion of the cylinder immediately below it. The skirt functions to form the interior surface of the pipe and, if desired, may be differentially driven in relation to the packer head so that both the head and the skirt may rotate at any desired relative speeds which are dictated by any instantaneous circumstances. The newly formed pipe may be removed from the cylindrical mould by applying pressure to one end of the pipe and forcing the pipe out of the mould.

Title: Automatic track control
Inventor: ZUCKER FRIEDHEIM
IPC: G11B7/09
Filed: 1995-06-29
Abstract: The invention concerns an optical scanning device which scans the frequency-warbled data tracks of a recording medium, the scanning light beam being reflected from the recording medium on to a four-quadrant photodetector (PD) with four photodiodes (A, B, C, D). The outputs of all four photodiodes (A, B, C, D) are added in an addition amplifier (V2). In order to be able to compensate automatically for offset voltages produced in the focussing-control loop by, for instance, temperature fluctuations, the output of the addition amplifier (V2) is connected to one input of a multiplier (M) to whose other input the track error signal is fed. The multiplier output is fed through a low-pass filter (TP) and as a compensation voltage to the focussing-control loop.

The second control circuit supplies another control signal for controlling the source (11) of heating current. The control signals from the first control circuit (13, 17, 18) are supplied to the first input and the control signal from the second control circuit (23, 27, 28) are supplied to the second input of an AND logical element (20), the output signal of which only switches on the controllable source (11) of heating current when both control circuits simultaneously supply output signals for temperatures lying below the respective set values.
