Abstract: 1,205,959. Texturing yarn. KLINGER MFG. CO. 13 Oct., 1967 [13 Oct., 1966], No. 46828/ 67. Headings DIF and D1W. Two or more yarns are heated and drawn in such a way as to produce different crimp development characteristics in the yarns, are combined and are then stuffer-box crimped. As described the two yarns are drawn between a pair of godets, the first and optionally the second godet being electrically heated. One yarn is wrapped more turns around the godets than the other yarn so as to receive more heat. Alternatively one yarn may be drawn to a greater extent than the other yarn. The stuffer-box has an arcuate setting chamber with a toothed wheel to carry the plug of crimped yarn therethrough. The filaments having the lower crimp development characteristics tend to lie on the outside of the crimped yarn. The filaments may however be interlaced by passing the yarn after the crimper through an air jet. The filaments of the two yarns have different affinities to dyes and delustrants due to the different pre-crimping treatments.

Title: Improvements relating to Internal Combustion Engines
IPC: F02B75/12
Filed: 1968-10-04
Abstract: 1,194,655. Combustion chambers; fuel injectors. DAIMLER-BENZ A.G. Oct. 4, 1968 [Oct. 5, 1967], No. 47126/68. Heading F1B. The invention relates to an air compression, fuel injection type internal combustion engine having provision for extraneous ignition, the piston 2 being formed with a bowl-type combustion chamber 3 about the axis of which air is rotating at the end of the compression stroke. Fuel is injected from an injector 8 on to the wall of the combustion chamber 3 in the same direction as the rotation of the air. A subsidiary combustion chamber 5 is formed in the cylinder head 4, the chamber being provided with the fuel injector 8 and with an ignition device 7, the chamber being in the form of an approximately hemispherical recess with a volume of from 5 to 20 % of the total combustion space, and being disposed in the region of a point at the periphery of the combustion chamber in the piston. The fuel nozzle is so disposed and constructed that in addition to a portion of fuel injected into the piston combustion chamber, another portion is injected obliquely against part of the wall of the subsidiary combustion chamber. In the embodiment shown in Figs. 1 and 2 the injection nozzle 8 is of the two-hole type, one jet of fuel 10 impinging on the wall of the piston combustion chamber 3, the second jet of fuel 9 impinging on the wall of the subsidiary combustion chamber. In a second embodiment the fuel injector is of the pintle type which discharges a single conical spray of fuel, the nozzle being so disposed that part of the spray impinges on the wall of the piston combustion chamber while the remaining part impinges on the wall of the subsidiary combustion chamber. The subsidiary chamber is formed with a lip 6 which serves to cause the fuel to swirl against the wall of the chamber, also to prevent fuel dripping down into the main chamber. The ignition device 7 may be a spark plug or a glow plug and the extraneous ignition may be discontinued, the engine then operating with selfignition.

The arms are downwardly and outwardly extending and fixed at their lower ends are clevises 19, 21 respectively in which workpiece engaging rollers 10,11 respectively are journalled in vertical shafts. The arms are biased toward one another by a tension spring 33 stretched between a pair of links 34, 35 which are pivotally attached to the clevises 19, 21 respectively at projections 37, 38, and are joined pivotally at 36. Coils of a linearly variable differential transformer are within a unit 39 which is fixed to a mounting block 40 having a downwardly extending shaft 41 supported in bearings carried by the roller clevis 21. A movable core 44 of the transformer is fixed to a shaft 45 coupled to an output shaft 46 of a micrometer 47. The micrometer barrel 48 is fixed to a mounting block 49 rotatably mounted by a shaft 50 to roller clevis 19. The micrometer setting as indicated on a counter 56, Fig. 3 and Fig. 2, (not shown), provides an accurate indication of the actual displacement of the rollers 10, 11 when the output voltage of the transformer is zero. The micrometer is normally left in a preset position and deviations therefrom produce an output voltage from the transformer, which may be used to actuate a reject signal.

Title: Improvements in and relating to dehydrated poultry meat products
IPC: A23B4/03
Filed: 1962-12-19
Abstract: A dehydrated poultry meat products is prepared by pressure-cooking the meat at about 15 pounds per square inch gauge pressure to increase the solid content, and thereafter forming the meat into chunks and drying the cooked meat to reduce the moisture content to less than about 4%.  According to an example, a whole eviscerated chicken is cooked in steam at a pressure of 15 lbs. per square inch gauge for one hour, whereby the solid content of the meat increases from about 20-25% to about 40-50% and the meat becomes very tender. After the cooking, the cooked chicken meat free of the broth and fat which drains off during the cooking process, is passed through a food chopper containing openings one-quarter inch in diameter to form cubes, or is sliced.  These cubes or slices are then dried on trays by air at a velocity of 10 feet per second and a temperature of 150 DEG F. for six to eight hours to bring the moisture content of the meat below 4%.  The dehydrated meat product obtained can be conveniently used in soups, gravies and casseroles, and rehydrated readily into a tasty, tender meat.  Salt or mono-sodium glutamate may be added to improve the flavour of the meat, preferably before the cooking; permissible antioxidants may be added before or during the cooking.

Abstract: 1532968 Recording media HONEYWELL Inc 4 Dec 1975 [4 Dec 1974] 49781/75 Heading B6C A recording medium of the type comprising a web of light-transmitting material having capsules uniformly distributed through the web, each capsule containing reflective particles in suspension whose orientation can be altered under the inflence of a force field, is characterized by the provision of at least two different types of capsule which have different response properties. Thus different traces can be produced on the recording medium in response to suitably chosen fields; these differences may be enhanced by different surface colourations of the particles in the two types of capsule. In the embodiment of Fig. 1, particles 8 are identical, but may be in a low-viscosity oil to produce capsules 6, or a high-viscosity oil in capsules 10. The recording head 19, which may be magnetic or electrostatic, is connected to a pulse generator 20 and a selector 22 which allows pulses of short or long duration. Short duration pulses will only affect the particles in capsules 6, but long duration pulses will alter the particle orientation in both groups of capsules. In an alternative embodiment, Fig. 2 (not shown), the groups of capsules contain different particles, e.g. nickel and stainless steel. The nickelcontaining capsules provide a trace when a low field strength is applied; higher field strengths result in both types of particle being orientated, thusproducing a different contrast or colour trace.
