Title: Improvements in or relating to a wall structure for transport containers
IPC: B61D27/00
Filed: 1948-03-31
Abstract: 640,975. Refrigerator cars etc.; radiators for cooling and heating vehicles. INDUSTRIAL PATENTS CORPORATION. March 31, 1948, No. 9083. Convention date, April 3, 1947. [Classes 29 and 64 (ii)] A refrigerated transportation container e.g. a rail car, motor van, aeroplane fuselage &c. has an insulated wall to which are removably secured a number of separate heat-exchange units 10 arranged side-byside and connected to supply and exhaust headers 12, 14 for refrigerating medium. Each unit is separately supported on a framework 15 of plywood fixed to the insulated wall of the container. The units curve at the top towards the centre of the car, and may cover substantially all of the walls, ceiling and floor. A bank of louvres 20 is fixed to each unit and spaced slightly from its exposed surface to space the goods from the surface and allow circulation of air. The upper louvres are inclined downwardly to direct warm air on to the surface of the unit, and the lower louvres direct the cooled air outwardly into the storage space. After the container has been refrigerated the units are evacuated by a pump 30 to insulate the container. When the outside temperature is lower than that desired in the container a heating medium may be passed through the heat-exchange units. Refrigerants used are salt, brine, calcium chloride brine, ammonia, methyl chloride, carbon dioxide, or tetra-aryl silicates.

Inventor: CHARLES ALBERT EDWARD
IPC: C01B21/46
Filed: 1916-06-28
Abstract: 107,255. Charles, A. E., and Lancaster, F. J. June 28, 1916. Gases and fumes, absorbing and treating with liquids.-Apparatus for condensing, absorbing, and otherwise treating nitric, hydrochloric, and like gases comprises a tower formed of a number of sections, each provided with one or more series of horizontal pipes 15 conveying a liquid either to cool or to heat the acid gases which ascend from an inlet 10 in the bottom section, and also with a perforated bottom 13 which supports packing 14. Each series of pipes 15 delivers the heating or cooling liquid into the open upturned ends 16 of the corresponding pipes in the section beneath, the delivery ends of the pipes being formed with a lip 17, Fig. 7, and with an obstruction 22 over which the liquid flows; this enables a leaking section of pipe to be detected from the level of liquid in the pipe. Tapered grooves 20, Fig. 6, beneath the bosses 18 in the walls of the tower through which the pipes 15 run collect the condensate that runs back along the pipes and causes it to run down the wall in a stream, and grooves 21 similarly treat condensate upon the walls. Outlets 11, 24 are provided in the bottom and top sections of the tower for condensate and uncondensed gases respectively. For the purification of acid gases, liquid reagents are sprayed in through inlets 25, 26 and the tower is heated by the pipes 15 to prevent condensation of the gases, which pass by the outlet 24 to absorbing-towers.

Title: Device for weaving memory matrices
IPC: G11C5/12
Filed: 1975-03-05
Abstract: 1467136 Producing core matrices VYCHISLITE TSENTR SIBIRS OTDELEN AKAD NAUK SSSR 5 March 1975 [11 March 1974] 9094/75 Heading H3B Ferrite core matrices are made by separating the end cores from prestrung stacks 4 by means of a comb 8 initially inclined at less than 45 degrees to the plane of the wires 3, and holding the separated row of cores whilst a wire helix 13 is threaded through them. The stacks are engaged with the comb by tilting the frame holding tensioned wires 3 or by air nozzle 9 so that the end cores are trapped between the comb and wires. Reverse tilting of air nozzle 10 returns the other cores of the stack to their original position. The comb is rotated to the position shown in Fig. 4 for threading by the helix 13. The comb 8 may have additional sections 16, 17 which are movable towards and away from the wires 3 to locate and hold the cores during threading, and may optionally be divided into individual groove sections each with its own drive device so that selected cores may be moved into locations where they are not threaded by the helix or where they form parallel rows separated by a distance equal to the helix diameter such that the cores in the rows become orthogonal when the helix is subsequently straightened. The comb grooves may be at alternate levels to assist this.

Title: Reclaiming synthetic rubber or rubber scrap containing synthetic rubber
IPC: C08J11/26
Filed: 1942-07-01
Abstract: Synthetic rubber, such as neoprene, that known under the Registered Trade Mark "Thiokol" and the diolefine types and their copolymers, or a rubber scrap containing natural and synthetic rubber is reclaimed by subjecting is to moist heat and preferably pressure in the presence of a monobasic aliphatic saturated acid of which the chain contains not less than four carbon atoms but does not contain hydroxyl groups, such as lauric and stearic acid.  The acid may be dissolved in a solvent capable of swelling the rubber and the solvent may be evaporated after mixing with the rubber.  In examples (1) a mixture of natural and synthetic rubber scrap is ground, mixed with a solution of lauric acid in naphtha and treated in a potheater for 5 hours at 190 lbs. live steam pressure, (2) ground neoprene G.N. tyre scrap is mixed with a solution of stearic acid in trichlorethylene and heated with water in an autoclan for 5 hours at 200 lbs. pressure. Neoprene, after treatment, is compatible with natural or other synthetic rubber, or natural, and is vulcanizable with sulphur. Reference has been directed by the Comptroller to Specifications 558,334 and 566,058.

Title: Improvements in or relating to self priming rotary pumps
IPC: F04D9/02
Filed: 1936-03-27
Abstract: 472,661. Centrifugal pumps. LA BOUR, H. E. March 27, 1936, No. 9209. [Class 110 (i)] During the priming of a centrifugal pump, the liquid and entrained air is discharged through a number of equidistant throats 66, 67, 68 and passes through a duct 62 to the vortex separating chamber 60. The liquid is then returned to the impeller chamber via a duct 63 and a number of equidistant throats 69, 70, 71. When the pump is primed, the return throats 69, 70, 71 act as additional discharge throats. If more fluid returns through one of the return throats than can be discharged through the next discharge throat, the excess tends to block the inflow from the next return throat. To avoid separating the entrained air from the liquid, the throats are tangential to the impeller casing. The ducts 62, 63 are parallel to one another and are separated by a wall 64. The ducts 63, 64 are clamped between members 40, 50 comprising the impeller chamber. In a modification, the throats discharge laterally into the ducts 62, 63.

Abstract: Varnish for separating the colour screen from the emulsion in photographic multicolourscreen material comprises a composition which includes a resin of the kind known under the Registered Trade Mark "Glyptal." A drying oil such as linseed oil or tung oil is included in the varnish. The composition Paralac includes these ingredients and to it may be added inert substances to aid the drying, examples being cellulose esters or ethers, e.g. cellulose dilaurate, dinitrolaurate diacetylpalmitate; or chlorinated rubber compounds such as Pergut, or metallic driers such as lead resinate, linolate or tungate. Drying may also be improved by adding polymerized vinyl ester resins such as Mowilith. A wetting agent is also added, e.g. the substance sold under the Registered Trade Mark "Perminal." Plasticizers of the type such as triarylphosphates, cyclohexanol are also added.  The solid is dissolved in benzene, toluene and xylene or substituted hydrocarbons, the solution containing about 12 \ba1/2\be per cent solid.  When benzyl cellulose is employed in the mixture a small percentage of alcohol is added and the solution is made more dilute.  In general the Paralac is diluted with four times its volume of benzene etc.; the Pergut or other drying product is dissolved in five times its weight of a mixture of benzene and xylene; and the Mowilith is dissolved to form a 25 per cent solution in benzene, the solutions being then mixed together. Specification 401,719 [Group XX], is referred to.

Filed: 1969-02-20
Abstract: 1,263,757. Counters. CHEMIEUND TANKANLAGENBAU KOMBINAT FURSTENWALDE VEB. 20 Feb., 1969, No. 9243/69. Heading G4D. A sealed magnetic reed relay ring counter for use with a petrol pump has input pulses applied to odd and even stages alternately. The counter is reset by energizing relay 70 which closes contacts 10 and 90 to hold up between +ve at 91 and - ve at 94. Input pulses from the feed line are applied through a bi-stable device to leads 92, 93 alternately. The first pulse on 92 operates relay 61 via diode 71, resistor 31, diode 30 and contact 10 to +ve. Relay 61 then holds over its own contacts 1 and 81, the latter shorting out relay 70 which falls back. The process repeats in respect of the next pulse on lead 93, and so on round the ring. Carry is effected at 95 to a further bi-stable device which feeds pulses alternately to input leads of the next decade. The device may receive simultaneous inputs and may have accessories such as printers, quantity and price preselectors and digital indicators.

Title: Accelerometer
IPC: G01P15/09
Filed: 1958-03-24
Abstract: 879,575. Accelerometers. TECHNICAL CERAMICS Ltd. (Gulton Manufacturing Corporation). March 24, 1958, No. 9296/58. Class 106 (3). [Also in Group XIII] An accelerometer comprises a housing, a chamber in said housing, an electro-mechanically sensitive body mounted in said chamber, means within said housing or in an external housing for containing gas under pressure, and means for releasing said gas into said chamber or into a further chamber surrounding said chamber upon reaching a temperature above a predetermined value in said chamber. An accelerometer for measuring vibration or shock comprises a housing 10, Fig. 1, secured by a stud 26 to the structure under measurement. The housing 10 is provided with a chamber 23 containing an electromechanically sensitive element 24 with mass load 25, and a chamber 11 into which gas under pressure is admitted, a filler plug 20 being removed and the gas forcing open a valve 12. When the temperature of the housing rises to a predetermined level, the increased gas pressure opens a valve 15 by acting on a pressure stop 16, and gas is admitted to a chamber 21, whence it is exhausted through a port 22. Expansion of the gas cools the chamber 23, so that the accelerometer can function in high-temperature environments. In another form, Fig. 4, gas is fed into the chamber 28 from an external chamber 35, and is released into the chamber 29 containing the member 24 when a valve 30 is opened by a solenoid 32 under the control of a temperature-sensitive element 34. In another form, Fig. 5, gas in a separate housing 42 is released through a channel 48 into the chamber 47 containing the member 24 when a valve 44 is opened under the action of a thermal control 46. At a predetermined lower temperature, a thermal control 45 closes the valve. A spring-loaded seal 49 acts as a non-return valve.

Abstract: 101,407. Siemens - Schuckertwerke. Sept. 4 1915, [Convention date]. Summing and differencing movements of varying extent.-In hauling or winding machinery in which indicators or safety devices are operated from the rope pulleys, means are provided for indicating the stretch or slip of the rope. For this purpose an indicator or relay circuit is provided comprising two variable resistances the contacts of which are actuated by the driving-pulley and an idle pulley respectively, in such a manner that, under normal conditions, the sum of the resistances is constant, the amount of stretch or slip being indicated by the variation of such sum. The rope passes over a winding-pulley t and idle pulleys s. The contacts of the rheostats v, ware operated by worm gearing from the winding-pulley t and one of the idle pulleys s so as to decrease one resistance as the other increases. The rheostats are in circuit with an ammeter or relay m, the reading of which indicates the amount of slip or stretching; a zeroizing-device n is provided. As the idle pulley s makes a greater number of revolutions when the rope is stretched due to the load, than on the return when light, the rheostat w is rotatably mounted and is slightly rotated against the friction of a brake e, each time by the engagement of the contact with tappets g. The relay m may be arranged to apply the brakes to the winding-pulley in case of excessive slip. In a modification, the contact of the rheostat w is actuated by a differential between the two idle pulleys s.
