Title: A Process and Apparatus for the Manufacture of Chocolate Mix.
IPC: A23G1/04
Filed: 1968-05-15
Abstract: 1,187,932. Chocolate. WERNER & PFLEIDERER. 15 May, 1968 [26 May, 1967], No. 23076/68. Heading A2B. A chocolate mix is prepared by subjecting the constituents in a first stage to a mixing and kneading to form a homogeneous basic mix, directly liquefying this mix in a second stage, subjecting the liquefied mix to a combined degassing and dewatering in a third stage under reduced pressure, and passing the resultant mix to a bin or a further processing stage without rolling and tumbling. Fig. 1 shows a suitable apparatus for carrying out the process of the invention. The liquid and solid ingredients (e.g. sugar, dried milk, cocoa, and cocoa butter) are introduced via belt weighing machines 5 and pipe lines 6 into a two shaft screw mixer-kneader 1, and the resulting homogeneous mix passes directly to high speed rotary pump 2 wherein the mix is liquefied. This liquefied mix then passes to the two-shaft interlocking screw conveyer 3, in which the mix is degassed and dewatered via vents 9 or a cupola 4 (Fig. 3, not shown) by which a vacuum may be applied. The product leaves via outlet 8 in liquid state and is passed for tableting (not shown). The entire apparatus is surrounded by jacketing 7 for heating or cooling.

Title: Compensating circuit for slow detectors
IPC: G01J5/14
Filed: 1965-06-01
Abstract: 1,063,173. Correction of photo-electric detector output signals. BECKMAN INDUSTRIES Inc. June 1, 1965 [June, 24, 1964], No.23208/65. Heading G1A. The thermal type of detector, such as a thermocouple, produces, for an alternating radiation input signal, an electrical output signal which is the integral of the input and lags it by 90 degrees. In order to compensate for this, the detector output, after having any D.C. signal removed by the coupling transformer 12, is differentiated to give an output at 18 which is a substantial replica of the radiation input signal. The necessary integrating negative feedback path in the amplifying stage 16 is provided by capacitor 13 connected to the output of the cathode follower. In an alternative arrangement the capacitor is in series with resistor 20.

[Class 40 (iii).] A scanning member, e.g. a drum 13, bearing a plurality of scanning elements, e.g. mirrors or lenses, translates a series of images 15, 16 of an object 1 over a plurality of scanning apertures 10, 11, 12 co-operating with a single transmission line fed from a cell 20, successive images 15, 16 being relatively displaced at rightangles to their direction of translation and each scanning element taking part in scanning more than one line of an image. The apertures 10, 11, 12 are spaced apart by a distance equal to or greater than the width of an image, and each in turn scans a line of an image, cooperating with a reflector 17, 18, 19 and the cell 20. The film 1 is moved intermittently, the mirror drum 13 having certain mirrors blackened to avoid scanning during the movement of the film. If the film is moved uniformly, the drum 13 has all its mirrors mounted tangentially. Each aperture 10, 11, 12 may be subdivided, the corresponding subdivisions being associated with a separate cell and transmission line. At the receiver three sources of light replace the apertures 10, 11, 12 and a screen is used to render only one effective at a time. A plurality of such scanning arrangements may co-operate to scan a picture in zones, one or more zones being scanned more finely than the others if desired. According to the Provisional Specification, each aperture may be associated with a separate transmission channel, the apertures being separated by a distanceless than the width of the picture.

Abstract: 532,039. Grinding and crushing. MELDAU, R. Aug 14, 1939, No. 23360. Convention date, Aug. 13, 1938. [Class 59] Relates. to a device for collecting the most finelydivided particles, or dust, produced by the dry grinding of material in a mill using freely, movable bodies such as balls. According to the invention, the upper part of the mill i: connected by a narrow slot with an independent casing or receiver, the slot being sufficiently narrow to prevent the passage of the grinding bodies while permitting free passage of the dust-containing gases. The receiver 2' may be of circular cross section, or may be shaped as shown, and the dust that collects in the receiver may be removed by a screw, by brushing, or by any suitable means. When the mill is a ball mill of the oscillating type, liquid may be added to the receiver so that the movement of the mill may be used to emulsify the dust with the liquid.

Title: Improvements in temperature indicating apparatus for gas turbine engines
IPC: F01D17/08
Filed: 1967-05-19
Abstract: 1,159,837. Measuring temperature electrically. GENERAL ELECTRIC CO. May 19, 1967 [Aug. 22, 1966], No. 23429/67. Heading G1N. The temperature T4 at the inlet 20, Fig. 1, of the turbine 22 stage of a gas turbine engine is obtained by measuring the air temperature T3 at the inlet to the combustion chamber 16 and adding to it, at 40, a signal obtained by combining the outputs of transducers 26, 30, 32 measuring respectively rotor speed N, combustion chamber inlet static pressure Ps3, and rate of fuel flow to the chamber Wf. The equation governing the combination of the various signals to give T4 includes a square root of T4 term and this is obtained by feeding the output of adding means 40 to a rooting circuit 42 and time delay 43, and injecting the resultant signal at a point 44 before the T3 term is added. The formula given is: The functions f of Ps3 and N are produced by function generators 48, 36, and a unit 33 supplies a signal A 4  proportional to the area of the turbine inlet 20, though this is normally fixed. The signal supplied by the dividing device 46 and representing wf.f(Ps3), may be derived alternatively by a Ps3 different circuit Fig. 2 (not shown); and the f(N) signal from 36 may be derived alternatively from a circuit Fig. 3 (not shown) which generates a different f(N) signal according to whether the engine is in steady operation or accelerating. Function generators (54, 56) continuously operate, and the appropriate output is selected at (58) by a device (60) which senses whether the measured speed N is less than or equal to a pre-set speed (62). The calculated temperature T4 may be used to control exhaust nozzle area, or to limit fuel flow.

Filed: 1973-05-17
Abstract: 1367436 Semi-conductor device mounting STANDARD TELEPHONES & CABLES Ltd 17 May 1973 23526/73 Heading H1K A substrate with flexible leads is made by attaching to a substrate body side by side lengths of wire each with an intermediate portion partially wrapped round and bonded to the body and ends extending from it, and removing part of each intermediate portion and of the underlying body material to provide a surface constituting a mounting location for a solid state device disposed between two sets of terminal areas, constituted by the newly formed ends of the wires lying flush with the surface. For example, enamelled copper wire is wound around a semi-cylindrical mandrel, e.g. of copper or plastics and a parallel auxiliary mandrel, the wire bonded to the mandrel surface with epoxy resin, the wire cut adjacent the auxiliary mandrel and the main mandrel machined to provide a flat surface in which the wire ends are exposed. In alternative forms the mandrel initially has flanged ends which are retained after machining and a rectangular aperture extending between them, or comprises a central portion, bounded by through slots inclined to each other but extending from one end parallel to its axis, and around which the wire is wound. Accurate spacing of the turns may be ensured by grooving the surface of the mandrel. The device, e.g. a light emitting diode or diode array is mounted on the machined surface and its bonding pads connected by flying leads to the flanking terminal areas. Where the mandrel is apertured the device is located on an inverted T section auxiliary substrate and is tested before being located in the aperture for connection (Fig. 8).
