Title: Process for the treatment of meat, meat-containing products and blood
IPC: A23B4/32
Filed: 1956-06-22
Abstract: Meat, meat-containing products and blood are treated with condensed alkali phosphates obtained by direct or indirect spraying in voluminous and readily soluble form and of bulk weight less than 600 g./1.  Direct spraying consists in spraying alkali orthophosphate solutions or solutions of condensed alkali phosphate glasses into a hot gas, while indirect spraying consists in first converting alkali orthophosphate solutions into a voluminous orthophosphate calcinate by spray-drying and then converting the calcinate into a voluminous condensed alkali phosphate by further heating.  In examples, condensed phosphates are used to maintain blood in a liquid condition, and as an additive to brine for ham pickling, the phosphates being modified in some examples by spray-drying in the presence of caustic soda or by treating the voluminous product with hydrogen peroxide subsequent to spray-drying.  Reference is also made to the use of condensed phosphates in the manufacture of sausages. Common salt may be incorporated with the phosphates of the invention either before or after spraying.  Specifications 714,500, 744,576 and 764,022 are referred to.

Abstract: 426,242. Alternating-current motors. HAYDON, A. W., 64, Ellsmere Avenue, Waterbury, Connecticut, U.S.A. July 2, 1934, No. 19500. Convention date, Aug. 9, 1933. [Class 35] Motors with unwound iron armatures.- In the field member of a single phase motor having two groups of polepieces, the angular displacement between polepieces of opposite polarity in the two groups is different and a single unwound rotor co-operates with all the polepieces. The motor is self starting and operates synchronously if the rotor is of hard steel, but otherwise as an induction motor. In the form shown the rotor consists of a ring of high hysteresis material 20 and the stator coil, which has a central core, is enclosed on one side by a disc having axial pole pieces 24, 25 and on the other side by a disc 22, shown in dotted lines, having shorter axial polepieces 26, 27. The polepieces 25, 26 co-operate to cause the motor to run at a twenty four pole speed after it has been brought up to that speed by the rotary field of the other set of polepieces. This other set comprises two sequences of four poles, the sequence being separated by the polepieces 25, 26 but the pitch of the second set corresponds to a twelve pole stator. Each sequence consists of two shaded poles 24 and two poles each consisting of a projection 27 on disc 22 and a radial polepiece 28 on a plate 23 which is placed alongside the disc 22 but separated therefrom by shading plates which lag the flux of polepieces 28.

Title: Translator for electric pulse code communication systems
IPC: H03M1/00
Filed: 1952-08-01
Abstract: 705,813. Pulse code modulation circuits. STANDARD TELEPHONES & CABLES, Ltd. (Federal Telecommunications Laboratories, Inc.). Aug. 1, 1952, No. 19514/52. Class 40 (5) Time modulated pulses are converted into pulse code groups by providing a scanning pulse train of the same recurrence frequency, a plurality of normally blocked coding circuits all connected to one of the pulse sources and one or more delay devices, connected to the other source, which sequentially condition the coding circuits. In one embodiment, a seven-level, three-unit simple addition binary coder comprises three normally blocked valves 32 ... 34, to which are applied simultaneously, over lead 51, the time modulated pulses from modulator 49. Any code pulses which are, at the same time, applied over leads 35 ... 37 respectively to the individual valves, then unblock them, the pulses being applied in succession to lead 56 through a distributer 55 to produce a code group. To produce the succession of pulse combinations on leads 35... 37, a pulse 58 from generator 47 is applied to a delay line 38 having equally spaced tappings 0 ... 6. The leads 35 ... 37 are connected in different combinations through resistances 57 to these tappings, so that at the instant when a time modulated pulse occurs a specific combination of valves will be receiving code pulses depending upon the modulating signal amplitude. The duration of pulse 58 is substantially equal to the delay between adjacent tappings on line 38. The switches 48, 50 may be operated to apply the modulated pulses from generator 49 to the delay line 38 and the unmodulated pulses from generator 47 to lead 51. The tapped delay line may be replaced by individual delay lines between the points 0-1, 0-2 &c. The invention may be applied to coders using any type of code with any number of units. Volume compression may be effected by causing selected extreme values of signal to produce the same code group, groups of adjacent tappings on the delay line being connected together for this purpose, Figs. 5, 6 (not shown). Specification 535,860 is referred to.

Filed: 1921-07-21
Abstract: 186,469. Colebrooke, A. H. S., and Williams, W. A. July 21, 1921. Vacuum tubes.-The filament of a thermionic valve is renewed by forming an opening in the bulb, removing the old filament, placing the new filament in position .by means of a guidetube, through which the filament is threaded before or after insertion in the bulb, and securing the filament to the leading-in wires. An aperture 1 is formed in the bulb at the tip or elsewhere, and hooks 2, 2a on the leading-in wires 3, 3<a> are opened for removing the old filament. A short length of tube is passed through the aperture and the grid 4, the filament 7 being threaded through the tube, and secured by working one end around a hook 2<a> and pinching the hook on to the filament. 'The tube is then withdrawn, the wires 3, 3a bent back into position, and the other end of the filament secured to the other hook 2. In another arrangement, the filament is threaded through a bent tube 12, Fig. 5 before insertion in the bulb, and the tube may be used as a handle for winding the end of the filament on the hook. A similar method may be used when the axis of the electrodes lies along the axis of the bulb. The hooks may be snipped off to remove the old filament and new hooks formed, or the filament mav be secured to each wire by a short-tube or bead.

Title: Improvements in or relating to heating and ventilating apparatus suitable for vehicles
Inventor: COPLEY DONALD WILLIAM
IPC: B60H1/00
Filed: 1961-06-01
Abstract: 959,469. Ventilating vehicles. S. SMITH & SONS (ENGLAND) Ltd. June 1, 1961, No. 19884/61. Heading F4V. In a vehicle heating and ventilating apparatus comprising an air inlet compartment 4, a heater 11, valve means 15a and 15b for controlling the proportions of air by-passing and/or passing over the heater, a main outlet duct 12b and an auxiliary outlet duct 18 respectively supplying outlet pipes 66 and a demister nozzle 25, the valves 15a and 15b are operated by actuating means arranged over a part of its movement simultaneously to apply an opening moment to one of the valves and a closing moment to the other. The actuating means comprises a cable 69 attached at 72 to a member 73 which is rotatable about an axis 74 and is formed with a cam track shaped to provide a rapid fall and rise 80 and a more gradual rise and fall 81. The cam track is engaged by a roller 83 mounted at the end of an arm 84 fixed to a spindle 85 to which the valve 15a is also secured. A spindle 75 to which the valve 15b is fixed is also fixed to a lever arm 77 connected by a link 78 to a pivot pin 79 secured to the member 73. Thus clockwise rotation of the member 73 tends first to close the valve 15b more tightly then valve 15a is quickly opened as the follower 83 is urged against the cam surface 80 by means of a spring 86 arranged around the pivot 85. Continued rotation of the cam then causes the valve 15b to open slowly and the valve 15a to close slowly. Each valve is provided with a resilient lining. The three remaining valves 21, 22 and 35 which control apertures between the inlet compartment 4 and auxiliary compartment 18, the main outlet compartment 12b and the auxiliary compartment, and the compartment 12b and outlet pipes 66 respectively are controlled by further actuating means (Figs. 6 and 7, not shown) employing cam tracks for valves 21 and 22 and a lost motion device for valve 35. Valve 21 is first quickly opened then gradually closed while valve 22 is gradually opened, the lost motion being taken up during this process resulting in a final abrupt closing of valve 35. The sequence of valve movements is given in Figs. 8 to 13 (not shown). The apparatus is constructed in upper and lower parts 1a and 1b adapted to be mounted on opposite sides of a bulkhead and a fan 8 is located in the air inlet compartment 4.
