Abstract: 521,047. Treating and storing food. SHEPHERD, G. R. (Westinghouse Electric & Manufacturing Co.). Nov. 11, 1938, No. 32861. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 5, 1939.] [Classes 28 (ii) and 49] [Also in Group III] Apparatus for treating and storing meat and other food comprises a compartment in which the food is supported, and ultra-violet light generating means over which air is circulated to be sterilized and activated, such air being caused to contact with the surface of the food, and being supplied to and withdrawn from the compartment by an external air-conditioning unit controlled by a thermostat and a humidistat located in the compartment, such unit having lines for supplying refrigerant or heat and supplying or withdrawing water, and being connected to the compartment by air inlet and return ducts. In Fig. 1, meat is stored in a room 2 or series of rooms, 2, 21 &c. which are entered through an ante-room 5. The air is circulated, by a fan, through a heat-exchanger and humidifier 9, pipes 8 and return ducts 10, the air-conditioner 9 being connected by refrigerant lines 12 to a condensing unit 11. Heat supply pipes 13 are used, in cold weather, in place of the refrigerant lines 12. External air is admitted to the air-conditioner 9 through a duct 14. Water for humidifying is supplied by the pipe 15 and condensed water is discharged through a pipe 16. Water may be removed from the air in the conditioner 9 by passing the air over cooling means which chills it below the dew point. The air-conditioner is controlled by a thermostat 17 and humidistat 18 through control circuits 19, 20, and the conditioned air is admitted to the rooms 2, 2<SP>1</SP> through orifices 21-23, beneath which are arranged ultra-violet light generators 24-26, the light having the major part of its radiations between 2,500 and 3,000 A.U. The lamps 24-26 are operated on a transformer 27 controlled by a switch 28. In modifications, the ultra-violet light generators are situated in the air-admission pipes 8, or the generators are arranged on the sides of the room, or in the duct 14 and in the return con- 'duct 10. The food-storage compartment may be constituted by a show case having a glass top and front wall, the ultra-violet light generators being disposed therein adjacent the vertex of the angle between the top and front walls.

Abstract: 1,078,006. Copying lathes. ERICH NETZSCH, [trading as GEBRUDER NETZSCH MASCHINENFABRIK]. Aug. 12, 1964 [Aug. 16, 19631, No. 32942/64. Heading B3T. [Also in Division G3] In a template-following system for controlling a lathe for shaping insulators from a raw material, such as porcelain, the cutting speed of the tool is reduced with a decrease in the radius of curvature of the edge being followed. As shown, Fig. 2, a tool 12, shaped to produce the re-entrant edges of the insulator 6, is mounted on a slide 11 to move horizontally relative to a carriage 9 which is vertically movable relative to a stationary friction plate 29. The template 14 is scanned by an oscillating photo-cell arrangement 15 in a steerable housing 13 coupled to cause rotation of a housing 22 for a motor-driven frictional wheel arrangement determining the horizontal and vertical movement of tool 12 and photo-cell arrangement 15. The speed of rotation of the motor 22, Fig. 3, (not shown), is controlled by the amplified output of photo-cells in a holder (44) on an extension of housing (13) scanning an outline (46). The outline (46) varies in width and the speed of rotation of the motor 22 is arranged to fall as the line width decreases. In operation, the tool 12 is moved rapidly along the vertical straight line of the template and then downwards following the contour 30, the speed of the motor and hence the tool cutting-rate being determined by the variable width line (46). A stop mechanism, not shown, is actuated when the work-piece is fully machined. The workpiece 1 is mounted on a driven head stock 3 and aligned by a tailstock 4 having a free-centre 5. The tailstock 4 and carriage 9 are counter-balanced over pulleys 7.

Title: Improvements in and relating to frequency control circuit arrangements
IPC: H03C3/24
Filed: 1947-12-15
Abstract: 629,929. Automatic frequency control systems. PHILIPS ELECTRICAL, Ltd. Dec. 15, 1947, No. 32980. Convention date, Sept. 20, 1946. Addition to 607,798. [Class 38 (iv)] [Also in Group XL (c)] The oscillations generated in a tuned circuit LC by a back-coupled valve O are modulated or controlled in frequency by applying a control voltage to the grid 7 of a further valve R connected across grid and cathode of the valve O and operating as a variable negative resistance. The two valves are reciprocally coupled, the anode of each being connected through capacities 6, 8 respectively to the grid of the other, and both valves have a three-point connection to the circuit LC. Variation of the control voltage on the grid 7 of the valve R alters the phase of the grid excitation of the valve O and thus adjusts the frequency. The grid condenser 2 is of small capacity to accentuate the phase shift.

Abstract: 471,174. Two-stroke engines; cylinders. DAIMLER-BENZ AKT.-GES. Nov. 28, 1935, No. 33006. Convention date, Dec. 1, 1934. [Class 7 (ii)] In a two-stroke engine, towards the end of, or after, the period of main scavenging, an additional scavenging stream is admitted by ports e<1>, directed, without rotation, towards the peripheral edge of the cylinder head, where eddies W of dead gas tend to collect. The main scavenging stream enters by ports d which may be radial or tungential, and be transverse or upwardly inclined ; it may be forced in by a pump or induced by the mass exit of the exhaust gas, the pump being only used at low speed. The additional stream is supplied at higher pressure, either by a separate pump or by a higher pressure stage of the same pump, which may be coaxial with and connected to a rotary valve f, controlling the closure of the auxiliary ports. In a mixture engine, rich mixture may be admitted through the additional ports e', air only being admitted through the main ports d. The Specification as open to inspection under Sect. 91 comprises also additional scavenging ports in the head or at the periphery of the combustion chamber arranged axially, radially or tangentially. This subject-matter does not appear in the Specification as accepted.

Title: Polymeric secondary amines
IPC: C08G73/02
Filed: 1962-08-28
Abstract: The invention comprises polymers containing the recurring structural unit: <FORM:0958863/C3/1> where R is a dimeric radical derived from a fat acid having an aliphatic hydrocarbon chain of 8 to 24 carbon atoms. The polymers are obtained by dimerizing a fat acid, converting the dimer to the corresponding dinitrile or diprimary diamine, and then hydrogenating the dinitrile or diamine e.g. at a pressure of 25 to 100 p.s.i.g. and a temperature of 200 DEG  to 290 DEG C. in the presence of a catalyst. Copolymers may be obtained by hydrogenating a mixture of dinitriles or a mixture of diprimary diamines. In examples polymers are obtained from a dimer dinitrile prepared from dimerized linoleic acid, and from a dimer diamine prepared by hydrogenating the dimer dinitrile; two of the examples describe copolymers prepared from adiponitrile and from metaxylylene diamine.

Abstract: 1,061,294. Photographic colour processes. EASTMAN KODAK CO. Aug. 21, 1963 [Aug. 28, 1962], No.33067/63. Heading G2C. Direct colour positive images are produced by imagewise exposing an internal type silver halide emulsion containing a colour coupler in the emulsion layer or an adjacent layer and developing the exposed layer with a colour developer in the presence of a hydrazide or a hydrazone which does not contain a quaternary atom and has the Formula R-NH-NH-R' or R-NH-N=R<2> where R is aryl or substituted aryl, R' is acyl and R<2> is alkylidene or substituted alkylidene. The aryl radical may be substituted by alkyl, amino, alkoxy or aryloxy, alkyl- or aryl-sulphonamides or -carbonamido or heterocyclic amino, sulphonamido or carbonamido radicals whereas the alkylidene radical may be substituted by an alkyl, aryl or heterocyclic radical. The hydrazide or hydrazone may be present in the emulsion or the developer, and the developer may be in the emulsion. Transferred direct positive dye images are produced by using colour coupler of structure DYE-LINK-(COUP-BALL)n or BALL-LINK- (COUP-SOL)n where DYE is a dye radical containing an acidic solubilizing radical, LINK is a connecting radical such as azo, azoxy, -Hg-, -O-, > CH-, =CH-, thio or dithio, which is split by the oxidation products of the colour developer, COUP is a coupler radical substituted in the coupler position with LINK, BALL is an organic radical of sufficient size to render the coupler non-diffusing in the alkaline developer solution, SOL is either a hydrogen atom or an acidic solubilizing group and n is 1 or 2 when LINK is alkylidene and 1 when LINK is other than alkylidene, and treating the exposed emulsion in the presence of a hydrazide or a hydrazone solution which breaks the LINK in the coupler to produce a diffusible dye which is transferred to a mordanted receiving sheet kept in contact with the exposed emulsion during development. The hydrazide or hydrazone may be incorporated in the receiving sheet in the mordanted layer or an overcoated layer. The emulsion may contain three layers sensitive to red, green and blue respectively, each layer containing a colour coupler forming or releasing a dye complementary in colour to the colour to which the emulsion is sensitive and normally barrier layers are put between the emulsions, one barrier layer acting as a filter layer.
