Title: Improvements in and relating to the manufacture of chocolate in divided form
IPC: A23G1/20
Filed: 1946-03-22
Abstract: 632,988. Chocolate-moulding machines. SHUTTLEWORTH & CO., Ltd., W. S., STANCLIFFE, G. B., and THOMAS, A. March 22, 1946, No. 8953. [Class 87 (ii)] Chocolate divided into small pieces, particularly for use as couverture chocolate, is produced by heating chocolate to a fluid state in a pan 1 having a stirrer 1a driven by a motor 2, feeding it, e.g. by a worm also driven by the motor 2, through a pipe 4 to a hopper 5 from which it passes in one or more streams onto a conveyer 11, the streams when cooled sufficiently being broken into short lengths. The worm, pipe 4 and hopper 5 have jackets 6, 7 through which hot water is circulated. A pipe 41 returns overflow to the pan 1. The chocolate may be sufficiently liquid to flow from the hopper 5 which has a bottom perforated with one or a row of holes to provide one or more streams. Alternatively the chocolate may viscous and extruded from the hopper by a piston or a worm 44, Fig. 13. This reduces or eliminates the cooling required. The hopper 5 may have a stirrer and a vibrator and its height above the conveyer may be adjustable. It is readily detachable from the rest of the apparatus for cleaning. The hopper bottom may be readily removable, e.g. by sliding in guides on the hopper, so as to be replaceable by a different one. Instead of thin streams, a broad stream may be fed from the hopper onto the conveyor, this broad stream being later subdivided by fixed knives 42, Fig. 12, or freely rotating disc knives. The conveyer belt (of fabric coated with plastic) may run through a long cooling chamber 25 in which a cold draught is maintained for cooling purposes. The streams of chocolate are broken by being bent by a roller 30a beyond the end of the conveyer against a knife edge 29. Instead of a roller a sloping plate may be used. Alternatively, reciprocating breaker 32, Fig. 8, may be used, set just beyond the knife edge 29 and raised and allowed to drop suddenly by a double cam 38 rotated by gears 36, 37. A roller 31 may be provided to hold down the strips of chocolate just before the knife edge 29. In a modification, a rotating cutter engages the strips of chocolate and cuts them sufficiently deeply to ensure that they will break up in leaving the conveyer or on subsequent handling. After delivering the chocolate to the breaker the return part of the conveyer may pass round an idler roller and then pass forward beyond the breaker, to feed broken chocolate, dropping down a chute from the breaker, to a receptacle. The conveyer may slope upwardly to the breaker. Tension adjusting means 16 for the conveyer 12 are provided. Instead of a belt conveyer, a cylindrical drum may be used.

Filed: 1975-03-04
Abstract: 1502983 Thermal switches LES CABLES DE LYON 4 March 1975 [8 March 1974] 8990/75 Heading H1N [Also in Division H2] A fire resistant electrical convection device comprises an insulating refractory box 28 containing a thermally responsive switch 29 and a fusible link 15 connected in series between two terminals 4, 9, the switch 29 comprising a movable contact 13 held in a contact closed position by a control rod 16 and a manually movable plate 18 which comprises or carries a thermally deformable or fusible material which deforms or fuses, when heated to allow the switch 29 to open. In one embodiment, Fig. 1, the housing 28 comprises two parts 1, 2 of magnesium silicate or steatite held together by nuts and bolts (3). A movable contact 12 on a flexible member 13 is biased into engagement with the terminal 4 by a rod 16 received in a slot in a nylon plate 18 . When a fire occurs, the plate 18 is deformed by the heat allowing the rod 16 to be raised by the contact carrier 13 thereby opening the switch 29. A connector screw 25 for the fuse link 15 is accessible by rotating the plate 18 about a pin 19 which causes the plate 18 to disengage the rod 16 and the switch 29 to open. In another embodiment, Fig. 3, a plate 34 is connected to a flexible blade 36 mounting a contact 35. The contact 35 is engaged by a contact 37 mounted on a rod 16 engaging a low melting point alloy 38 in a cup 39. When the alloy 38 melts, the rod 16 is biased upwardly through the cup 39 by springs (51) (Fig. 6, not shown) causing the contact 37 to disengage the contact 35. The terminal 4 for clamping cable wires 30 comprises plates 31, 32 and screws 33 made of a material, e.g. molybdenum stainless steel, having a lower coefficient of expansion than the wires 30 and the plate 34 so that the clamping pressure of the plates 31, 32 will not be reduced on overheating.

Title: Improvements in and relating to Filling-feeler Mechanism for Looms.
Inventor: JACKSON SIMEON SCHOON
IPC: D03D51/34
Filed: 1918-10-29
Abstract: 129,612. Jackson, S. S. Oct. 29, 1918. Weft-feeler arrangements.-In a weft-feeler device comprising a pair of differential feeler members and a controller rest and a controller-rest governor positioned thereby, a controller for the weft-replenishing or stopping mechanism co-acts with the controller rest to re-set automatically the feelar devices bv a forward movement of the controller rest produced by the weft mass in the shuttle. The invention is described as applied to the weft-feelsr arrangement described in Specification 129,190, in which a contact member a is mounted in slots in the rear ends of slides 1, 2 and is pivoted at a<1> to the slide 1; but the member a may be dispensed with. The front ends of the slides 1, 2 are pivoted to levers 10, 9 free to turn on a pin 11 and normally drawn rearwards by springs 12. A controller rest 14 is pivoted to the lever 9 and has a projection 14<b>, normally resting en a governor 16 secured to the slide 1, and a slot 14<a> engaging the cranked end 18 of a controller 19 secured to a shaft 20. When the weft is exhausted to the pre-determined extent, the governor 16 is moved from under the controller rest 14 and the controller 19 falls, turning the shaft 20 to allow a catch to be engaged by the weft hammer to initiate weft-replenishment or stop the loom. A full bobbin moves the lever 9 sufficiently far forwards to cause the co-operation of the controller end 18 and the rear end of the slot 14<a> to hold up the controller rest irrespective of the position of the governor 16, so that the feeler devices are automatically re-set.

Title: Improvements in and relating to hard compositions
IPC: C04B35/111
Filed: 1944-05-15
Abstract: A hard sintered material for making cutting-tools consists of alumina to which has been added a bonding agent consisting of silica or a compound of silica and alumina so that the silica content of the product is between 1.5 and 10 per cent, the ingredients being finely ground and intimately mixed prior to sintering.  The bonding-agent is preferably bentonite and/or kaolin.  In order to assist sintering, a fluxing-agent such as fluorspar is added in amount up to 5 per cent. The alumina should be in the dehydrated form.  The ingredients are mixed in wet or dry condition, the product being subsequently dried if wet mixing has been used.  Preferably, the ingredients are mixed and ground in a ball mill, the balls being made either of a similar mixture or of sintered tungsten carbide and cobalt since admixtures of these materials will not decrease the hardness of the composition. The product is then pressed into blocks, granulated to pass a 10-100 mesh sieve, and again pressed into blocks of the desired shape at a pressure of about 10 tons per square inch.  If these blocks have to be worked to shape, they may be heated to a temperature below 1000 DEG  C., preferably 600 DEG  C.  They are then heated to a sintering temperature of 1450-1700 DEG  C. for several hours.  If tungsten carbide balls have been used for grinding, the drying, pre-sintering and sintering should be carried out in a non-oxidizing atmosphere or a vacuum.  The materials are preferably employed as tips for cutting-tools and may be secured by clamps or adhesive.

Abstract: 673,439. Distilling shale. STANDARD OIL DEVELOPMENT CO. April 14, 1950 [June 16, 1949], No. 9283/50. Drawings to Specification. Class 55 (i). In a fluidized process for distilling oil shale or the like in which the heat required for the distillation is supplied by burning the spent shale from the distillation zone in a separate fluidized heater and returning hot combustion residue to the distillation zone, the average carbon concentration in the distillation zone and in the heater is maintained below 0.7 per cent by weight, thereby to reduce entrainment of particles having a size of less than 20Á. The residue circulated from the heater to the distillation zone is preferably substantially carbon free and the circulation rate lies between 5-20 lbs. of residue per lb. of fresh shale charged. A proportion of the spent shale from the distillation zone may be discarded according to the heat requirements of the system or alternatively where the heat generated in the heater is in excess of that required for the process a cooling fluid, for example water, may be circulated through a coil disposed within the heater. The distillation zone is maintained at a temperature pf 900-1200‹ F preferably 950-1100‹ F., and the amounts of spent shale from the distillation zone rejected and fed to the heater respectively may be controlled automatically by a thermocouple disposed within the heater and arranged to operate suitable slide valves.
