Title: Drying apparatus for air permeable material
IPC: D06F34/26
Filed: 1961-06-29
Abstract: 915,647. Drying clothes. WHIRLPOOL CORPORATION. June 29, 1961 [Sept. 29, 1960], No. 23615/61. Class 34 (2). A drying apparatus for air permeable material such as fabric comprises a casing having a drum rotatably mounted therein provided with a perforate cylindrical wall in contact with which a suction nozzle is positioned for applying a suction to the wall, means for applying suction to the nozzle and means for rotating the drum to enable it to tumble the material therein, the drying apparatus separating moisture or cleaning fluid from the material by passage through the perforate wall and suction nozzle. A dry cleaning or domestic laundry machine comprises a rotary drum 26, Fig. 2, within a casing 14 of a cabinet 10, and a suction nozzle having an end 64 resiliently mounted against a perforated, central cylindrical portion 32 of the drum wall to separate cleaning fluid or moisture from the clothes in the drum as it rotates by passages through the perforated wall and suction nozzle. The fluid or moisture from the drum enters into a closed fluid flow circuit comprising a first series of conduits 65, 69, 76, Fig. 1, which connect the nozzle to the inlet 74 of a vacuum pump 73, a second series of conduits 78, 79 connecting the outlet 75 of the pump by a twoway valve 77 either to a drain (not shown) or the casing 14 respectively, and a third conduit 71 connecting a separator 70, which also is mounted between the conduits 69 and 76, to the casing. The separator both separates fluff &c. in a filter 119 from the circulating fluid and acts as a liquid trap, only the gaseous medium passing through the conduit 76 to the pump, while the liquid flows through conduit 71 to the casing. Electrical heating elements 102, 103 are mounted in grooves 104 in the casing and extend substantially around the entire circumference of the drum to act both as water heaters in the wash cycle and to vaporize moisture during drying, which heaters are disconnected by solenoids actuated by thermostats in a housing 66 in the conduit 65 when the temperature of the fluid leaving the drum exceeds a predetermined value. Water is introduced into the drum by a solenoid-controlled pipe 145 through an opening 109 having a hinged flap 110 and ambient air also enters the casing and drum therethrough at a predetermined suction within the drum. Tumbling is achieved within the drum by arcuate ribs 100 which have the intermediate portion of minimum height located substantially over the centre line of the nozzle 62 to minimize the spacing between the perforated section 32 and fabrics bridging the baffles and so minimize loss of vacuum beneath the baffles by the nozzle.

Patent GB-736222-A (GB)
Title: A new or improved automatically operable by-pass valve
Inventor: PAWLING FRANK
IPC: F15B21/00
Filed: 1952-09-23
Abstract: 736,222. Lubricating systems. EXACTOR, Ltd. Sept. 23, 1953 [Sept. 23, 1952], No. 23873/52. Class 12 (3). A by-pass valve is automatically operable in response to reversal of the direction of flow of fluid in a main conduit to close a by-pass around a section of the main conduit and to open the by-pass on the beginning of flow at the downstream end of the section. In the diagram shown, the by-pass valve is used in a lubricating system having several outlets through which flow of lubricant is controlled by metering devices. A section 100 of the main conduit is shown provided with metering devices 101. In the arrangement shown grease from the main conduit enters the by-pass valve at 22 and bypasses the section 100, passing through connections 24, 25, 17, 14, 11 to the main conduit. When the direction of flow is reversed, grease enters the by-pass valve at 10, moves a valve 40 to the left, and passes through connection 12 to one end of a director valve D thereby moving it to the left, to allow the grease to pass through' connection 13 to one end of a valve A. This valve moves to the left to allow the grease to pass through the connection 17. The movement of the valve D connects the grease to the outlet 21 so that grease is supplied to all the metering devices 101 in the section 100. Eventually grease returns to the by-pass valve through opening 31 and passes through connection 30 to one end of a pilot valve C. This valve is then moved to the right, whereby grease passes through connections 17, 18, 19 to the end of a change-over valve B. This valve moves to the left allowing the grease through connection 17 to pass through connections 26, 23 to the outlet 22. There is thus a clear path for the grease from 10 to 22 and the section 100 is by-passed, until the flow in the main circuit is again reversed. The valve D is provided with a pin 104 which protrudes when lubricant flows from connection 10 to connection 22. The by-pass valve may be incorporated in a lubricating system described in Specification 727,239.

Patent GB-985614-A (GB)
Title: Improvements relating to the production of branched polymers
IPC: C08F2/38
Filed: 1963-06-17
Abstract: Branched polymers are made by polymerizing at least one monomer which is a conjugated diene or a vinyl-substituted aromatic compound in the presence of an organomonolithium initiator and reacting the resulting lithium terminated polymer with a compound having at least three reactive sites capable of reaction with the carbonlithium bond of the polymer by adding such compound to the unquenched reaction mixture so a branched polymer is produced by reaction between said compound and a plurality of polymer molecules. The preferred organo-monolithium compounds have the formula RLi where R is an aliphatic, cycloaliphatic or aromatic radical having 1 to 20 carbon atoms.  The polyfunctional treating agent having at least 3 reactive sites may be a polyepoxide, polyisocyanate, polyimine, polyaldehyde, polyketone, polyanhydride, polyester or a polyhalide.  The preferred polyepoxides are epoxidized liquid polybutadiene and epoxidized vegetable oils such as epoxidized soybean oil and epoxidized linseed oil.  The preferred polyisocyanates have the formula (R(NCO)m where R is a polyvalent organic radical which can be aliphatic, cycloaliphatic or aromatic and contains from 2 to 30 carbon atoms and m is an integer of 3 or more.  The polyimines are preferably those containing 3 or more aziridine rings as represented by the formula <FORM:0985614/C3/1> where each R can be hydrogen, alkyl, aryl or cycloalkyl radicals or combinations thereof, the total of the R groups containing up to 20 carbon atoms.  The aziridine rings can be attached to a carbon, phosphorus or sulphur atom.  The polyaldehydes and polyketones are represented by compounds such as 1,4,7-naphthene tricarboxylaldehyde and 1,3,6-hexanetrione. Examples of polyanhydrides and polyesters are pyromellitic dianhydride, styrene-maleic anhydride copolymer and glycerol tristearates. The preferred polyhalides are silicon tetrahalides, trihalosilanes and polyhalogen substituted hydrocarbons.  The amount of polyfunctional treating agent used is generally in the range 0.1 to 1.5 equivalents of treating agent based on the lithium present in the polymer, and after the polymers have been so treated they are recovered by the conventional methods. In the examples polybutadiene, butadiene/ styrene block copolymers and ordinary copolymers of butadiene and styrene are treated with liquid epoxidized polybutadiene; hexa(2-methyl-1-aziridinyl) -triphosphatriazine; styrene-maleic anhydridride copolymer; pyromellitic dianhydride; polyaryl polyisocyanate and silicon tetrachloride.  The treated polymers can be compounded and vulcanized in the normal manner.

Patent GB-587378-A (GB)
Title: Improvements in or relating to the manufacture of ethylene
IPC: C07C1/24
Filed: 1944-12-04
Abstract: Ethylene is produced directly under pressure by subjecting ethanol to contact with a dehydration catalyst at a pressure between 350 and 1500 atmospheres and at high temperature preferably 300-600 DEG  C., and if desired cooling and/or scrubbing the ethylene obtained.  The ethylene produced is contacted with an ethylene polymerization catalyst while still at an elevated temperature and pressure to produce polymerization products. Dehydration catalysts include acid catalysts such as phosphoric acid which may be suspended on an inert porous material such as coke or pumice, cadmium phosphate, and inorganic catalysts such as alumina and activated clays. Polymerization catalysts include oxygen, peroxides such as hydrogen peroxide, alkyl and acyl peroxides and alkyl hydroperoxides; per acids and their salts such as persuccinic acid, alkali persulphates, percarbonates and perborates, amine oxide, hydrazine, oximes; and organo-metallic compounds such as lithium butyl.  For oxygen catalyst the polymerization temperature is greater than 100 DEG  C., and the pressure exceeds 500 atmospheres.  For catalysts such as per compounds, the temperature is preferably 60 DEG  to 150 DEG  C. and the pressure 70 to 1000 atmospheres.  It is advantageous to use the same pressure for dehydration and polymerization.  Some cooling of the dehydration products is generally necessary and the crude ethylene should be separated from the dehydration catalyst. Liquid polymerization products are obtained when temperatures of 300-400 DEG C. and pressures of 50-100 atmospheres are employed. Interpolymers with compounds having carbon-carbon double bonds may also be obtained by adding such compounds after dehydration. Dehydration is preferably conducted in a hot reaction zone such as a tubular reaction vessel and the dehydration products are then passed continuously through a cooler and then into a second reaction zone for polymerization.  In examples: (1) dehydration is effected at 310 DEG  C. and 1500 atmospheres pressure with orthophosphoric acid as catalyst; (2) using the same catalyst dehydration is carried out at 300 DEG  C. and 300 atmospheres.  The temperature is lowered to 120 DEG  C. and polymerization is effected in the presence of benzoyl peroxide. Specifications 317,500, [Class 2 (iii)], 471,590, 497,643, 578,584 and 8070/40 (as open to inspection under Sect. 91) are referred to. In the first Provisional Specification, the dehydration catalysts also include concentrated sulphuric acid and caustic soda and the dehydration pressure is above 50 atmospheres.  The second Provisional Specification states that dehydration and polymerization may be carried out simultaneously.
