Title: Process for resolving solutions or liquid mixtures into their constituents by cooling and crystallisation
IPC: B01D9/02
Filed: 1936-06-24
Abstract: 463,845. Solidifying liquids by cooling. GES. FUR LINDE'S EISMASCHINEN AKT.- GES., and KRAUSE, G. A. June 24, 1936, No. 17592. Convention date, July 10, 1935, Addition to 429,474. [Class 29] The process described in the parent Specification is modified by cooling the liquid, e.g. milk, until only a core of unfrozen liquid remains, and effecting the freezing of the core, without further cooling, by equalization of the temperature throughout the mass. The liquid may be cooled to an extent greater than that required to solidify the entire mass, and the temperature equalization effected in a bath at a temperature of from 2 to 4‹ C. To prevent the complete freezing of the liquid at the apex of a conical freezing cell, the apex is coated with an insulating layer of oil paint. Alternatively, the circulation of the cooling brine around the apex of the cell is modified to prevent complete freezing.

Abstract: 403,690. Compound sheet materials. VULCAN ASBESTOS-CEMENT CO., Ltd., 292, High Holborn, London, and WRIGHT, A. H. J., Medveza Gora, Higham, Rochester, Kent. June 22, 1932, No. 17648. [Class 140.] A panel or sheet for building &c. purposes consists of a sheet of asbestos or a mixture containing asbestos, faced with wood veneer and strengthened by having a fabric glued to the other side. One or both surfaces of the panel may be further coated with metal, or with paint, lacquer, varnish, distemper &c., which may in turn be covered with a substance comprising a cellulose derivative. The wood veneer may be glued direct to the asbestos sheet by a casein adhesive, or may be gluod to an intermediate layer of fabric. A cellulose derivative adhesive may be used for glueing the fabric to the asbestos sheet. Specification 364,354 is referred to. The Provisional Specification describes also panels consisting of an asbestos sheet covered on one or both sides with fabric, which may be further covered on one or both sides with metal, wood veneer, paint &c., and then, if desired, with a substance comprising cellulose or a cellulose derivative, and panels consisting of an asbestos sheet with wood veneer stuck directly to both sides. The fabric-covered panel may be filled, smoothed, and grained, or a photographic transfer of a wood grain may be applied. The metal layer may be applied electrolytically or by spraying.

Title: Electronic sensor
IPC: G01B7/00
Filed: 1973-04-12
Abstract: 1425239 Linkwork TESA SA 12 April 1973 [18 May 1972] 17683/73 Heading F2K An electronic sensor includes a lever system whereby irrespective of the movement (i.e. up or down) of a measuring key (not shown) fast on a lever 4, a lamella 18, which forms part of a transducer 20, always moves in the one direction (i.e. downwards) against the opposing bias of a spring 26 such that the signal supplied by the transducer is always in the same direction. As shown, the lever 4 is secured via a member 3 to a 1st lever 10, the combined lever unit 4, 3, 10 being pivoted via a shaft 5 between forked ends 2 of a housing 1. The 1st lever 10 has forked ends 11 between which a 2nd lever 12 is pivoted via a shaft 21, the 2nd lever 12 carrying at one end a 1st stop member 14, having limited radial movement in clearance holes 16 in the forked ends 11 of the 1st lever 10, and at its other end the 2nd lever 12 carries the lamella 18. A 2nd stop member 28 comprises an eccentrically and axially adjustable stop 29-34 which engages the 2nd lever 12. The arrangement is such that on upward movement of the measuring key lever 4 the whole lever unit pivots clockwise about shaft 5 to downwardly move the transducer lamella 18, the lever 12 pivoted at 21 on the 1st lever 10 being maintained by the spring 26 and 1st stop member 14 as a rigid extension of the 1st lever 10. On downward movement of the measuring key lever 4, the 1st lever 10 pivots anti-clockwise about shaft 5 and upwardly moves the pivot shaft 21 of the 2nd lever 12 on the 1st lever 10, such movement being converted into clockwise i.e. downward movement of the 2nd lever 12 via the 2nd stop member 29-34, the clearance hole 16 permitting relative movement therein of the 1st stop member 14 during this relative movement of the 1st and 2nd levers 10, 12. The eccentric and axial adjustment of the 2nd stop 29-34 permits adjustment of the pivoting geometry of 2nd lever 12 relative to 1st lever 10 to modify the supply signals from the transducer as required.

Envelopes.-Relates to apparatus of the kind described in Specification 18833/12 for making seamless envelopes and bags by depositing paper pulp by suction on wire gauze or like patterns. According to the present invention, the liquid pulp is contained in a vat 1, through which extends an air-inlet pipe 3, controlled by a valve 2, and provided with branches 5, one of which opens into each pattern 4, its upper end being at a higher level than that of the suction pipe 11. The pulp is introduced through a pipe 6 provided with a valve 7. The suction pipes 11 are inserted in the bottom of the vat in communication with the discharge chamber 10 and pipe 8. Horizontal partitions 12 having perforations out of register with each other are placed in the lower part of the vat, and baffles 17 are arranged on the bottom of the vat and lower partition to lengthen the path and reduce the speed of the flow. The lower end 16 of the pattern 4 is fitted air-tight on a cover 13, which is mounted on a plate 12. To facilitate the removal of the patterns, a carrier 15 is attached to the supporting plate, while the air inlet pipe 3 serves to break the high vacuum inside them.

Classes 64(1) and 64(3) A heat exchanger comprises a pile of heat transmitting elements providing alternate helical and radial channels for the heat absorbing and heat transmitting media respectively, the radial channels connecting a chamber surrounding the pile with a collecting chamber inside the pile, and the two fluids flowing generally in contraflow through the heat exchanger. The heat transmitting elements preferably comprise coils 2c spaced apart by ribs 2d, the ribs defining radially expending channels between adjacent tube coils. Fig. 1 shows the heat exchanger 2 disposed within a container 1 connected by inlet and outlet pipes 4, 6 into the circuit of a central heating plant. Water from the central heating system flows through the radial channels in the heat exchanger and thereby heats water flowing in the helical channels, the water heated in the helical channels being withdrawn e.g. for baths, through a conduit 17 and cold water being supplied for heating through a conduit 18. A thermostatically controlled valve (not shown) may be provided in the container outlet 6 to regulate the amount of boiler water flowing to the heat exchanger thereby limiting the temperature of the heated water passing to the conduit 17. Two or more heat exchangers connected in series may be disposed in the container 1 (see Fig. 3, not shown).

Abstract: 295,574. Podszus, L. Aug. 13, 1927, [Convention date]. Addition to 274,302. Spray carburettors.-The parent Specification describes a floatless carburettor in which the fuel valve is opened, through the medium of a lever, bv a suction-actuated piston the movement of which is determined by a stop carried by one arm of a lever actuated by a sliding air-control valve. According to the invention, the air valve is of the rotatable type and actuates the lever through an adjustable eccentric on its spindle. The body a has a flange at one end for attachment to the engine and at its other end is provided with a butterfly valve f for controlling the air. Fuel flowing past a valve n is mixed with air entering a valved conduit h and the aerated fuel passes through a conduit l at the end of which it meets a cross current of atomizing air through an orifice in line with the sprayer b. The fuel valve is lifted, through a lever o pivoted at t, by the suction-actuated piston p, the upward movement of which is limited by a stop z adjustably carried on one arm of a lever s, the other arm of which rests on an adjustable eccentric w on the spindle of the air valve f. The stop z is adjusted so as to permit a slight lift of the fuel valve at starting when the air valve is closed. Suction is transmitted to the top of the piston through a duct q.
