Abstract: 1,022,525. Printing and/or embossing apparatus. TETRA A.B. Aug. 4, 1964 [Sept. 4, 1963], No. 31547/64. Headings B6C and B6J. [Also in Division B4] In a device for producing a locally defined improved and/or printed pattern (with or without perforations) repeated at predetermined intervals on a moving web of sheet material, an impressing and/or printing tool 3, which carries the pattern, is pivotally suspended above the web 10 on a horizontal axle 5. The tool 3 is mounted on a push-rod 2 which is fastened to the piston or diaphragm of a pneumatic device 1, so that the tool 3 can be applied to or withdrawn from the web. A backing roller 8 is disposed beneath the web with its axle 9 positioned a distance A, Fig. 2 (not shown), in front of the axle 5, in the direction of movement of the web. The tool 3 is designed in such a way that the leading edge or point thereof is spaced in front of the axle 5 by the same distance A. In operation, the tool 3, initially resting against an adjustable step 11, is first lowered into contact with the moving web 10. The web carries the tool forward so that it swings about the axle 5, and after leaving the web, runs over an inking roller 12. This is due to sufficient velocity being imparted to the tool by the web. Having been inked, the tool is retracted when the pneumatic pressure is released, by for example, a spring; and it swings back to the stop 11 under its own weight. An alternative to having the tool 3 pneumatically mounted is to have the backing roll 8, pneumatically mounted.

Abstract: 456,034. Centrifugal pumps. ROWLEY, H. E. G., 9, Warwick Court, Gray's Inn, London.-(Master Filters, Inc. ; 713, East 3rd Street, Los Angeles, U.S.A.) Nov. 19, 1935, No. 32021. [Class 110 (i)] A centrifugal ejector pump for evaporating and withdrawing a volatile liquid and subsequently compressing and condensing the vapour comprises rotating tubes 21 with multistage ejectors 17. The motive fluid is drawn up the inclined wall of a rotating bowl 10 and passes through vertical tubes 13 with radial jets 14 to the ejectors 17. The vapour surrounding the ejectors is entrained with the motive fluid and the pressure in the inlet pipe 8 reduced to cause further evaporization. The entrained vapour and motive fluid is discharged through the involute compression tubes 21 and collects in the bottom of the housing 1 to be drawn off through a pipe 35. The condensate is cooled by tubes 25 through which cooling liquid is forced by a pump 28. The part of the condensate forming the motive fluid passes through a filter 42 and ports 46 leading to the bowl 10. The pump is regulated by controlling the supply of motive fluid to the jets 17. This is effected by turning an apertured disc 47 co-operating with the ports 46. A lug 50 depends from the disc 47 and is engaged by the crank 51 of an operating rod 52. A liquid seal between the inlet pipe 8 and the suction 7 comprises a disc 11 secured to the pipe 8 and blades 15 carried by the lower impeller disc 5. A similar seal is formed between the bowl 10 and a fixed sleeve 36. The multi-stage ejectors are made by coiling a strip of metal.

Title: Improvements in or relating to internal-combustion pumps
IPC: F04F1/16
Filed: 1922-03-06
Abstract: 198,966. Christie, S. P. March 6, 1922. Explosion apparatus.-In an internal combustion pump, the fuel-injection pump 15 is operated through a lever 13 by the exhaust valve 8 during its closing movement. The exhaust conduit 7 extends into the combustion chamber and serves as a guide for the stem 9 of the exhaust valve. The valve 8 opens by gravity assisted by suction created by the outstroke of the liquid in the pipe 2, and is closed by the impact of the returning liquid. A light non-return valve 11 prevents entrance of air through the conduit 7 when the valve 8 is open. During the outstroke, the air inlet valves 5, 6 are opened by suction; during the return stroke, the exhaust products are forced through the conduit 7, and after the valve 8 has been closed, the liquid compresses the fuel mixture in the chamber 1. The fuel is delivered through a jet 20 into a chamber 3 containing the sparking plug 4, and, if desired, through a jet 21 into the chamber 1. A pipe 23, which may be heated, is arranged in the path of the jet 21. The apparatus may be used for propelling ships. Specification 182,570 is referred to.

Title: Method of increasing the ohmic resistance of pure iron, especially electrolytic iron
IPC: C23C16/22
Filed: 1925-12-21
Abstract: 245,753. Siemens & Halske Akt.-Ges. Jan. 9, 1925, [Convention datel. Cementation.-In a method of increasing the ohmic resistance of bodies of pure iron, especially electrolytic iron, especially when in the form of sheets of any thickness by adding foreign substances to the iron, silicon or boron or a compound of these substances is brought into contact with the iron and by use of an increased temperature the silicon &c. is deposited thereon, the treated body then being subjected to a higher temperature, preferably at a high vacuum, to cause the coating to adhere firmly thereto. The coated iron may be subjected to a higher temperature in a vacuum, whereby the silicon or boron is incorporated into the iron. A coating of silicon or an iron sheet may be produced by passing a current of silicon hydride over the sheet at a raised temperature. In an example, a dynamo plate is placed in a tube of refractory material and the air removed therefrom by a current of hydrogen. When the air has been removed completely, the tube is heated to a temperature of 600-700‹ C. and silicon hydride is passed into the tube. Part of the latter gas is dissociated into silicon and hydrogen, the silicon being deposited on the sheet. To increase the adherence of the coating, the supply of silicon hydride is cut off, the temperature raised to 1000‹ C. and a current of hydrogen passed through the tube. The process may be repeated one or several times. In a modification, the coating is produced by embedding the iron in finely-powdered silicon or ferro-silicon and subjecting the same to a tempering process.
