Inventor: LORING FREDERICK HENRY
IPC: B01D1/18
Filed: 1919-05-01
Abstract: 134,487. Loring, F. H. May 1, 1919. Mixing-apparatus, suspending; treating substances with liquids and gases.-In centrifugal apparatus for atomizing liquids and mixing with solids or for mixing and drying liquids and solids, the solid material is fed by a pipe 35 into pockets 37, and is forced by stationary brushes 36 through a revolving grid 34 into a conical hopper 7. Liquid is fed through a tubular shaft 1 carrying a bearing 2 and a driving-pulley 5 into a revolving basket 10 provided with a porous lining 14 and apertures 15. Atomized liquid is thus sprayed on to the material falling through the grid 34. To assist the atomization of the liquid, the basket 10 may be filled with charcoal &c. Cleaning wires 41 carried by the revolving grid 34 may be provided. Hot air or gas may be delivered through the pipe 35 and, when required for drying, may also be admitted through an opening in the casing below the basket 10. To lubricate the various parts of the machine, oil is delivered by the pipe 16 to a bearing 8; its course is indicated by the arrows. The oil finally passes by a duct 30 to a channel 32, whence it is conveyed by a pipe 33 to a pump which delivers it to the pipe 16. In order to make the bearings dust-proof, a washer 38 is fixed to the upper part of the grid framing, and a similar washer 40 is secured thereto below the grid. An induction or continuous-current motor may be substituted for the pulley 5.

Title: Dried fruit and vegetable slices
IPC: A23C19/086
Filed: 1978-03-21
Abstract: The foodstuffs are cleaned and cut into pieces, for example slices. Before freeze-drying, the pieces are then dipped into a solution which prevents discoloration, for example a solution containing 0.1 to 0.5% of ascorbic acid. After freeze-drying, the foodstuff pieces are transferred to a packaging which contains a protective gas, for example nitrogen or carbonic acid, and which is gas- and water-tight. The process gives crisp slices which can be eaten straight from the packaging and which are softened in the mouth by the action of saliva.
Patent GB-827381-A (GB)
Title: Improvements relating to film casting
Inventor: LOCKE RONALD STANLEY
IPC: B29C48/08
Filed: 1956-04-12
Abstract: In film-forming processes wherein organic film-forming material in the liquid state is extruded from a casting hopper on to a moving surface through a slot having its long axis substantially perpendicular to the direction of <PICT:0827381/IV (a)/1> <PICT:0827381/IV (a)/2> movement of the surface and is allowed to harden on the surface, a slow and slight transverse relative movement is provided between the hopper and the surface.  The film-forming material may be a cellulose ester of a paraffinic monocarboxylic acid having 2 to 4 carbon atoms, and the making of films from a solution of cellulose acetate in a volatile solvent is particularly described, but the process may be used also in wet-casting and in casting films from welts.  A number of other film-forming materials are specified. The moving surface may be an endless band, and preferably the casting hopper is traversed slowly and to a slight extent across the direction of travel of the film during casting, but alternatively the casting surface may be traversed while the hopper is kept stationary. In a preferred embodiment, cellulose acetate film of thickness 0.5-2 mils. and of 25-50 inches width is cast at 40-150 ft. per min. and the hopper is traversed 0.25-1.5 inches each way, at right angles to the direction of travel of the film, during 5-15 minutes.  The film is then stripped from the band, the remaining solvent is evaporated, and the film is trimmed and reeled in known manner.  Apparatus as shown comprises a casting band 3, a drum 5, a hopper 1 having a slot 4 of controllable width, the long axis of which is substantially perpendicular to the direction of movement of the casting band, and means for traversing the hopper comprising a pair of traverse guide members 2 on which the hopper is slidably supported, in combination with a rod 8 pivotably attached to one side of the hopper and operated by an eccentric.  Alternative means for producing the transverse motion are also referred to. Film-forming material may be supplied at a uniform rate to the hopper by a metering pump 6 supplied by a hose 7.  By means of the traversing movement described, registration of high spots in successive layers of film wound on a spool is avoided, and a spool of film more nearly uniform in diameter along its length (i.e. perpendicular to the film length) is obtained.

Title: Method and apparatus for producing semiconductive structures
IPC: H01L21/00
Filed: 1955-04-21
Abstract: 810,862. Photo-electric control systems. PHILCO CORPORATION. April 21, 1955 [April 21, 1954], No. 11590/55. Class 40 (3). [Also in Group XX] In the manufacture of semi-conductors use is made of the selective light transmission of different thicknesses of semi-conductor. Thus when white light is directed through the semiconductor during an electrolytic etching process the predominating colour reaching an observer's eye or a photo-electric detector is an indication of the thickness of the semi-conductor and enables the operator to terminate or modify the etching process. In the arrangement of Fig. 1, jets 12, 13 of a translucent electrolytic etching fluid impinge on opposite sides of a silicon wafer and white light is directed on to one side by a lamp 40 and is viewed by an observer at 45 on the other side of the semiconductor. An etching current provided by battery 32 flows through the semi-conductor and the jets and is adjustable by resistor 34. When the operator views a particular colour he may either terminate etching or, by means of resistor 34, slow it down. Alternatively, the jets may be moved to another part of the semiconductor or changed in shape, area, or pressure. In the arrangement of Fig. 2 jets 12, 13 of translucent electrolytic etching fluid are directed on to opposite sides of a silicon web while an etching current supplied by battery 32 and adjustable by resistor 34 flows through the semi-conductor and the jets. White light from lamp 40 is " chopped " by conventional chopper disc 55 and directed through the semi-conductor to photo cells 57 and 71 sensitive respectively to red and orange. The outputs of the cells are amplified by triodes 60, 72 respectively and applied to peak detectors 66, 73. The two detectors are interconnected through relay winding 50 and a diode 80. Thus as etching proceeds a voltage indicative of the strength of the transmitted red light is built up at the cathode of peak detector 66 but is unable to operate relay 50 because of diode 80. As the orange content of the transmitted light increases, however, the output of peak detector 73 increases until, when it exceeds that of detector 66, relay 50 is operated, etching ceases, and an alarm 53 is operated. The gain of the " orange " channel would normally be higher than that of the red. Modifications.-Chemical instead of electrolytic, and bath instead of jet etching may be controlled. The thickness may be built up instead of reduced, for example by means of evaporated or electro-plated deposits of semiconductor. A light source may traverse a body until a part of the required thickness is found when deposition of metallic elements such as emitter and collector may commence. Specification 805,291, [Group XXXVI], is referred to.

Abstract: 677,367. Race games. GRANTHAM, W. May 16, 1950, No. 12140/50. Class 132 (ii). In an electrically operated race game of the type wherein scoring  effected by a competitor causes closure of electric contacts and completes an electric circuit so as to advance along a track a symbol such as a model greyhound, momentary closure of one of two pairs of contacts by a scoring ball initiates closure of a circuit including a motor remote from its symbol and adapted to advance the symbol in stages, said circuit including relay means for holding the circuit closed, means being provided for breaking the circuit after the symbol has advanced one or two stages depending upon which pair of contacts has been closed. Ten tracks are provided each having a playing table for balls which can roll down channels comprising two sets, one with contacts 11 for advancing the symbol one stage and one with contacts 15 for advancing two stages. The symbol is carried on a bogie and is coupled to the motor either by a screw and nut advancing arrangement or by a chain drive. The means for breaking the circuit comprises a double-pole double-throw switch 13a, 13b actuated by the rotation of the wheels carrying the chain or by projections on the chain. When the single stage contacts 11 are made, a relay 12 is energized to move a switch 12a to the left. This energizes a relay 14, the contacts of which supply current to the motor. The circuit breaker 13a, 13b is thrown over to the right when a stage has been traversed. thus opening the circuit of relay 14 and stopping the motor. If, however, the two-stage contacts 15 are made, a relay 16 is energized and closes a switch 16a to complete a circuit through relays 14, 16 to energize the motor. After one stage the breaker 13a, 13b is thrown to the right and thus completes a circuit through relay 14, switch 12a and breaker 13b, whereupon the motor operates a further stage and the switch 16a opens. At the end of this second stage the breaker 13a, 13b again is thrown to the left to de-energize relay 14 and stop the motor. Each symbol may actuate an individual terminal limit switch to prevent further scoring by the other symbols or a single limit switch may be common to all tracks. A visual or audible signal may be given when any symbol reaches the end of its track. Means may be provided for returning all the symbols to the start.
