Title: Method of dry cleaning
IPC: D06F43/00
Filed: 1934-04-13
Abstract: A process for dry-cleaning fabrics or articles of clothing, consists in treating the materials in a washing-machine with a solvent, withdrawing the solvent, adding water thereto and homogenizing the mixture, and then returning the mixture to the washing-machine. Solvent contained in a washing machine 5, Fig. 1, is forced by a pump 9 through a filter 8 from which it flows through a pipe 10 in which it is mixed with water admitted in regulated amount from an injector 13, and the mixture flows into a homogenizer 11.  The homogeneous dispersion of water in solvent then passes through a pipe 12 to the washing machine.  The homogenization of water and solvent may be assisted by dry-cleaning soaps or dispersing-agents as described in Specification 401,752.  For example, gasoline, naphtha, carbontetrachloride or trichlorethylene is mixed with 1 per cent by weight of a mixture containing oleic acid, naphtha, and mahogany <PICT:0435575/III/1> <PICT:0435575/III/2> sodium sulphate. Homogenized dispersion of water in a solvent containing this mixture are optically clear.  The process is preferably effected continuously in which water is continuously mixed with the flow of solvent in amount equal to that removed by the fabrics in the washing-machine. The water injector consists of a main tank 14, connected to the solvent pipe 10 through a pipe 15 and injector needle valve 17 and above which is mounted a water supply tank 26 from which water flows to the main tank through a pipe 27 and valve 29.  Water flows by gravity from the valve 17 through an inner pipe 20 to the solvent flowing under pressure in the pipe 10.  An equalizing pressure is maintained in the tank 14, by a pipe 21 connected to the outer pipe 15, which opens into the tank provided with an air relief valve 24. The pressure is read on a gauge 25.  Water drawn off from the tank is replaced by solvent which may be drawn off through a cock 16<a>.  The homogenizer consists of an inner perforated casing 34 mounted in an outer vessel, and containing perforated tubes 31 closed at the top and surrounded by absorbent fibres such as cotton cloth 37.  Solvent and admixed water enters at the bottom of the pipes and then passes through the perforations to the absorbent material in the interstices of which the admixed water is broken up into small particles which are then absorbed by the solvent containing the dispersing agent. The resulting dispersion which is free from any static electrical charges passes through the perforations 36 into the space 35 from which it flows through a pipe 12 to the washing machine. Specification 392,931 also is referred to.

Abstract: 1,150,843. Lever-operated switches. ERNST LEITZ G.m.b.H. 13 March, 1967 [15 March, 1966], No. 11615/67. Heading H1N. A remote control device for a transparency projector having motor drives for picture changing and forward and reverse magazine feed has a rocker arm 4, pivoted at 5 and normally held in either of two stable positions by a spring- loaded roller 8 engaging in the angles 9, 10 at the sides of a projection 6. An abutment 19, on one face of the lever 4, co-operates with a lever 20 which, in turn, engages the operating member of a snap-action changeover switch 22, so that if arm 4 is moved clockwise, lever 20 is depressed and centre blade 21 engages upper contact 23. If arm 4 is moved anti-clockwise lever 20 is allowed to rise and the snap action returns contact 21 to engagement with lower contact 24. This switch controls the direction of movement of the magazine. A second lever 14 is similarly depressed by either of two abutments 11, 12 and actuates a switch 16 irrespective of the direction in which arm 4 is moved. This switch 16 actuates the picture change but the positions of the abutments 11, 12 are such that a predetermined lost motion exists between them and the lever 14. The arrangement is thus such that the desired direction of movement of the magazine is selected by pressing arm 4, and thus projection 6, to the appropriate side of roller 8 and thereafter the picture change is made by pressing the arm further, in the same direction, to actuate the switch 16.

Filed: 1966-03-17
Abstract: A process for the dehydrogenation and condensation of a secondary alcohol to a ketone comprises contacting the alcohol at elevated temperature with a catalyst comprising Ni, ZnO and an alkali or alkaline earth metal phosphate.  The feedstock alcohol is preferably C3- 8.  Examples describe the dehydrogenation of hexanols-2 and -3, themselves prepared by hydration of n-hexenes.  Part of the product comprised hexanones-2 and -3 which was recycled to the reaction zone. Product comprising C12 unsaturated ketones was found to contain small amounts of the corresponding saturated ketones. Hydrogenation of the mixture over a PtO2 catalyst yielded two isomeric C12 ketones viz. 7-methyl undecanone-5 and 7-ethyldecanone-5.ALSO:Dehydrogenation catalysts are made by mixing an alkali or alkaline earth metal phosphate with an aqueous slurry formed from nickel formate, zinc oxide and ammonia, drying the mixture, reacting in a stream of air and finally reducing at elevated temperature in a stream of hydrogen. In examples the catalyst is seived to 10-18 mesh.  Compositions containing Ca3(PO4)2, Li3PO4 and p  Mg3(PO4)2 are described.

Abstract: 1,254,474. Service line couplings for railway vehicles. GERMANY, MINISTRY OF TRANSPORT. 6 March, 1969, No. 11960/69. Heading B7T. An air pipe line coupling 1 within an automatic central buffer coupler 2 is provided with a pivoted cover 13 to close the coupling mouth when in an uncoupled condition, wherein when the coupling is coupled to a counter coupling the cover is pivoted to an out-of-use position by means of a cam engaging in a notch 22 of a housing 5 which moves forward during the coupling operation, the air pressure within the pipe line then causing a rod 18 to move a leaf spring 19 to the position A such that if an uncoupling occurs unintentionally when the pipe line is still pressurized, the housing 5 will not be able to move back to its uncoupled position due to abutment 27 contacting the spring 19, and hence the cover does not close the mouth thereby allowing air to escape and operate the vehicle brakes. The rod 18 is actuated by a diaphragm 15 located in a chamber 26 which is in communication with the air pipe 31. The end of the air line is located by a bayonet connection within housing 5, which housing is moved forwards during coupling by an arm 3 of the buffer coupling 2. In the event of an intended uncoupling the air pressure in the pipe line is first relieved. In a modification, the cover 15 is directly prevented from closing the mouth during an unintentional uncoupling by being contacted at its pivoted end by a piston-rod, the piston of which is acted upon by the air pressure in the pipe line.
