Abstract: 1,003,097. Packaging machines. RALSTON PURINA CO. June 13, 1963 [June 19, 1962], No. 23583/63. Heading B8C. [Also in Divisions A2 and B5] In a process and apparatus for making and packaging sterilized food pellets, particularly animal food pellets, to ensure that the pellets are substantially free from pathogens, meal, e.g. comprising wheat, maize, oats, soybeans, meat and dried milk, is fed, from a hopper 1, Fig. 1, into a screw conveyer 5 into which water is injected at 11, e.g. to bring the moisture content to between 25 and 30% by weight, and steam is injected at 13, e.g. to bring the temperature of the moistened meal to between 160 and 210 F. The meal passes from the conveyer into an extruder 9 comprising a screw 43 rotating in a casing 45 having adjacent its inlet, a jacket 53 for cooling water and, adjacent its outlet, a steam jacket 55 for heat-sterilizing the meal (see Division B5). A generally rectangular tube T of meal is extruded from the nozzle 113 of the extruder, Fig. 4. Fat melted under sterilized conditions in an atmosphere of nitrogen in a tank 123, Fig. 1, is passed through a pipe 129, a pump 125 and a flexible pipe 127, into the upper end of a tubular needle 17 and from its lower end into the tube of meal T, which is then sliced into fat-impregnated pellets P, Fig. 4, by a rotary cutter 19 having a shaft 149 carrying three cutting arms 147, which co-operate with a fixed shearing bar 181. The pellets P pass, through a rotating drying drum 21, Fig. 1, the outlet 23 from a tank 15 and an open valve 27 into a chamber 25 having an outlet 29 which is closed by a valve 31. The valve 27 is then closed and the pressure in the chamber 25 is increased by admitting sterilized compressed air through a valve 241. The valve 31 is then opened and the pellets are ejected from the chamber into a plastic bag B, e.g. of polyethylene, fitted around the outlet 29. The mouth of the filled bag is heat-sealed at H by a device 33. The chamber 25 and the bagging station are located in an enclosure 35, e.g. a tent of plastic material, in which sterile or aseptic conditions are maintained by washing with an aseptic solution and by recirculating the air, through an air-filter, by means of a blower 39.

Filed: 1930-08-11
Abstract: 361,368. Actuating controllers; switchgear structures. BROOKHIRST SWITCHGEAR, Ltd., and HIRST, J. A., Northgate Works, Chester. Aug. 11, 1930, No. 23933. [Classes 38 (iii) and 38 (v).] Electrically released switches.-A change-over alternating-current starting switch combined with a contactor type circuit-breaker, is provided with an auxiliary switch in the circuit-breaker closing coil circuit, which auxiliary switch is closed only when the change over switch makes the starting connections, the closing coil circuit through the auxiliary switch being completed through an overload switch controlled by a differential expansion element, heated by a coil connected in the main motor circuit. In Fig. 9 a star-delta switch C is operated by a toggle connected handle, and spring biassed to the delta position, so that the closing coil b3 of the current-breaker B is opened at contacts c, b. The switch c is first moved to its " star " position and an auxiliary switch c is closed to energize the circuit-breaker B, which is maintained over auxiliary contacts b. In this position the motor may be niched. After a time the switch E is released and moves to its delta position. In this position the motor circuit is protected by fuses F, the opening of the circuit-breaker upon failure of voltage and by the thermal overload switches. During the return of the switch c to its delta position it may be arrested at mid stroke by a cam and detent, so that force is necessary to move it to its full " on position. The arrangement may be adopted for auto-transformer starting. Each thermal switch, Fig. 12, comprises a bi-metallic strip h3, heated by a coil H, and operating on a lever h7 to rotate a lever h10, Fig. 13. The tail h11 on the lever h10 bears against the tail e10 of the overload switch E, to maintain it closed against the action of a spring e7. When the overload is sufficiently great, the tail h11 enters a slot e13, and the switch E opens. The switch E is automatically reset by the opening of the isolating switch. The isolating switch 1, Fig. 9, is provided with mechanical interlocks which prevent the switch being closed when the cover is open, and also prevent the cover being opened when the switch is on. The change-over switch is of a simple spring toggle type, and is fully described with reference to Figs. 4 to 8 (not shown). The fuses, Fig. 19, are of the enclosed type with contacts f<2> at opposite ends, the lower parts f<3> being shaped as cylinders, hexagonal or other prisms of such sizes as fit corresponding sockets f4 of starting gear of the same rating. The Provisional Specification states that the invention is applicable to starters of the straight on type.

Title: Improvements in or relating to electrical non-metallic resistors and the manufacture thereof
IPC: H01B1/04
Filed: 1930-08-11
Abstract: <PICT:0366605/III/1> <PICT:0366605/III/2> A resistance of non-metallic material such as silicon carbide is cured by heat treating at a temperature below the dissociation temperature of the non-metallic material while it is in an atmosphere containing substantial proportions of at least one of the chemical constituents of the resistor and while it is in the field of an electric current. Such resistors are stated to have a positive temperature coefficient. The material used is a mixture of ordinary silicon carbide, having an apparent density of about 1,7 grams per cc. and dense silicon carbide from a furnace, having an apparent density of about 2,6 grams per cc. or more. The two kinds of silicon carbide are separately powdered and mixed with a small amount of fine carbon and silicate of soda in water. For a resistor of high resistivity the following proportions are given: 12,8 parts dense silicon carbide 10 to 20 mesh ; 8,5 parts dense silicon carbide 60 and finer mesh ; 76,2 parts ordinary silicon carbide and 2,5 parts 100 mesh and finer carbon and sodium silicate solution of 28 DEG  B<\>ae.  For relatively low resistivity the following proportions are given: 54,0 parts 10 to 20 mesh dense silicon carbide ; 27,0 parts 60 and finer mesh dense silicon carbide ; 13,5 parts ordinary silicon carbide ; 5,5 parts 100 and finer mesh carbon and sodium silicate solution 28 DEG  B<\>ae.  The mixture is tamped into a mould, or small portions of the mixture may be introduced into the mould at a time by passing through a gyratory screen.  When the mould is filled, excess is struck off with a straight-edge and pressure is applied to compact the material in the mould.  A hollow resistor may be made by introducing a readily carbonizable core such as sash cord into the mould.  The moulded resistor is allowed to set and then baked at about 600 DEG  C.  It is then dipped into a slip or slurry containing fine sand, carbon, and water and allowed to dry, and is then further heated to about 2200 DEG  C. in a furnace.  As shown, the refractory bottom 1 of the furnace is covered to a depth of 2 inches with bedding material 3 of finely divided silicon dioxide and carbon in such proportions as to give off silicon vapour when heated.  The resistors 4 are arranged end to end between the electrodes 2 and joined by graphite blocks 5 and a paste of graphite, silicon, and water.  They are then covered with the bedding mixture 3 and current is passed between the electrodes 2. Resistors of large diameter, e.g. over \ba5/8\be inch diameter, may be heated in several steps, the resistors being taken out and turned about its axis through 90 DEG  or 180 DEG  between the steps so as to obtain uniformity.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the modification shown in Fig. 2 (Cancelled) in which the resistors 4 are arranged parallel to the path of the current but to one side of the principal path.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in electrodes for use in electrochemical processes
Inventor: GILLIBRAND MAURICE IVAN
IPC: H01M12/06
Filed: 1960-07-11
Abstract: Carbon electrodes for use in electrochemical processes involving the ionization of a gas supplied to the electrode, e.g. hydrogen and oxygen, are prepared by adding suitable finely divided metallic catalysts, e.g. gold, platinum, palladium, rhodium and nickel, to activated carbon powder, treating the whole with a hydrophobic binding material, and moulding under sufficient pressure to produce a porous body of the desired shape.  The catalyst may be added by impregnating the carbon powder with a solution of a salt of the metal and heating to reduce the salt to the metal.  Hydrophobic binding material may be polytetrafluorethylene, which may be added to the impregnated carbon powder as an emulsion, and then precipitated thereon by the addition of acetone.  The resulting suspension is then filtered, washed and dried, and ground to a coarse powder, which is moulded at a pressure of 1-2 tons/sq. inch to produce a highly porous body.  The body thus obtained may be sintered at 400 DEG C. for 2 minutes in order to increase its mechanical strength.
