Title: Improvements in or relating to machines for cleaning floors or carpets
Inventor: VERHAGEN EDWARD L
IPC: A47L9/32
Filed: 1953-12-28
Abstract: 740,526. Floor polishing machines. REGINA CORPORATION. Dec. 28, 1953; No. 35990/53. Class 138(1) A floor polisher comprises a base 15, Fig. 2, a motor housing 14 mounted on the base, the housing being formed of two portions 20, 21, the portion 20 being cup-shaped and having circumferential ribs 29, 30, the rib 30 having a flange 31 thereon, and the portion 21 being an end plate or cap for the portion 20, the external diameter of the cap 21 being substantially equal to that of the flange 31, a ring 18 mounted on and surrounding the portion 20 and bearing on the ribs 29, 30 for rotary movement relative to the portion 20 about a horizontal axis, the ring being held against axial movement by the flange 31 and the enlarged rim 32 of the cap, and a handle 17 secured in a clamp 19 on the ring. The motor 11 drives polishing brushes 10 through worm shafts 12, gearing and vertical shafts (not shown). A casing 16 mounted on the base plate 15 has a slot 37, Fig. 3, through which the handle 17 projects and is free to move. A flanged bumper 33 surrounds the base plate and a flange 36 on the casing. The pivoting point of the handle is in the motor axis and is near to the centre of gravity of the machine, so that when the machine is lifted by the handle the small turning moment tending to tip the machine from its horizontal position is overcome by the friction between the ring 18 and the housing 14.

Title: Silicon-containing thioalcohols and thioethers
IPC: C07F7/02
Filed: 1955-12-15
Abstract: The invention comprises certain new silyl mercaptans and silyl thioethers and a general method of preparing such compounds which comprises reacting a silane RSiX3, where R is an aliphatic olefinically unsaturated radical and X is an alkyl or alkoxy radical or a halogen atom, with hydrogen sulphide in the absence of a hydrogen halide acceptor.  The reaction is accelerated by heating and by irradiation with ultra-violet light or by the use of Friedel-Crafts catalysts, platinum and other metals of Group VIII of the Periodic Table.  The pressure may be at or above atmospheric level.  In the examples: (1) di-[b -(trichlorosilyl)ethyl]-sulphide is prepared by heating vinyl trichlorosilane with H2S in an autoclave at 220 DEG  C.; (2) the reaction of (1) is repeated in the presence of platinized asbestos; (3) di[b -(triethoxysilyl)ethyl]-sulphide and b -(triethoxysilyl)-ethylmercaptan are prepared by refluxing vinyl triethoxysilane with H2S under ultra-violet light. In the absence of ultra-violet light, little reaction occurs and the product is mainly mercaptan; (4) di-[b -(trimethylsilyl)-ethyl]-sulphide and b -(trimethylsilyl)-ethylmercaptan are prepared by refluxing vinyl trimethylsilane and H2 under ultra-violet light; (5) di[-#t-(trimethylsilyl)-propyl]-sulphide is prepared from allyl trimethylsilane and H2S under ultra-violet light.  The compounds are useful as lubricant additives.
Patent GB-1033630-A (GB)
Title: Drum filter with plastic filter elements
IPC: B01D33/06
Filed: 1964-09-03
Abstract: Sections of the outer surface of a horizontally-disposed rotary drum suction filter each consist of a portion of a cylinder (e.g. one twelfth, circumferentially), having on its convex surface a plurality of spaced parallel ridges defining grooves extending in the direction of the curve of the surface, and having openings through it providing communication between the grooves and its inner surface.  Each section has a sheet filter medium covering its convex side and attached to the outside rim of the section along all four edges. Each element thus formed rests on three radially spaced axial ribs 24, 22, 26, Fig. 6 (not shown), secured to the drum surface proper, 12.  The element is fastened to the drum by spaced screws 30, extending through that one of the axial rims which is leading in the direction of drum rotation, and p  engaging threaded plates extending between rib 26 under that element and rib 24 under the adjacent element.  The filtrate compartments formed by the axial ribs are interrupted at the centre of the length of the drum by a fixed annular valve element 16, Fig. 3 (not shown), which encircles the drum at this point. The drum interior is also interrupted by two transverse discs at the region within the valve element, these discs 34, 36, being connected by axially extending tie members, to form a passageway 38 for radially inward flow of filtrate.  Disc 34 has a central opening connected by a pipe 18 with an opening in one end wall 31 of the drum.  The pipe 18 extends through end wall 31 and through an opening in a fixed framework 13 in which it is rotatably mounted, and connects with a stationary pipe elbow 20 to which vacuum is applied.  The inner surface of the valve element 16 is closed from the "1 o'clock" position to the "4 o'clock" position to cut off the filtrate compartments at that region from vacuum and allow air-venting through the filter medium during cake-removal; elsewhere the inner surface has an elongated opening to provide communication with passageway 38.  The openings 47 in the grooves of each filter element are at the "trailing" end of the element, so that as the element progressively inverts after the "12 o'clock" position, any trapped filtrate is caught between drum surface 12 and the under-surface of the element and cannot re-wet the filter medium.

Title: Method for production of electroluminescent storage devices
IPC: H04N3/14
Filed: 1969-07-17
Abstract: 1,270,844. Cathode-ray storage display tubes. XEROX CORP. 17 July, 1969 [19 July, 1968], No. 36120/69. Heading H1D. [Also in Divisions C4 and G2] In a process of making an electroluminescent storage device which may be included as a target in an evacuated storage tube as in Fig. 9 of Specification 1,201,374, portions of a transparent conductive layer on a transparent substrate are converted into an opaque state whereby the portions prevent subsequently deposited light-sensitive layers overlying the portions from being exposed to actinic radiation through the substrate. An electroluminescent device is made by providing a layer of photoresist (14) on a layer of SnO (12) on a glass substrate 10. The photo-resist is exposed through a mask (18, Fig. 1, not shown) and the unexposed portions removed. The exposed portions of SnO are reduced to tin (24) electrolytically and the portions of tin and photo-resist (24, 20) are coated with a layer of photo-resist and electroluminescent material (26, Fig. 3, not shown). The device is exposed to light through the substrate 10 and the tin portions (24) and unexposed portions of the photoresist-electroluminescent layer removed to leave photoresist-electroluminescent portions 32 on photoresist and tin-oxide portions 22, 20. The gaps between portions are filled and covered with epoxy resin 33 as electrical and moisture insulation and the upper surface with a field effect semi-conductor control layer 34. The control layer may comprise ZnO, CdO or PbO or a layer of CdS, ZnS, CdSe or ZnO with an insulating layer on it, if charge retention properties are inadequate. Alternatively a barrier layer may be made by suitable doping to provide a PN junction. In operation, a charge pattern is established on surface 34 and this governs the resistivity between adjacent portions and hence the light emitted by the electroluminescent portions 32. The charge pattern may be established by full-frame or line-by-line imagewise exposure of the charged surface with one or more scanning light point sources in the case of a layer of ZnO or other photoconductor, by corona discharge through a shaped mask, by corona discharge of an X-Y matrix or pin matrix in an imagewise fashion or by a scanning corona discharge and negative ion deposition is instanced. The tin oxide layer may be replaced by Cu 2 I 2 , In 2 O 3 , AgI, CuS or antimony chloride. Reference is made to Specification 1,235,310.

Filed: 1960-10-25
Abstract: 956,721. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 25, 1960 [Nov. 17, 1959], No. 36572/60. Heading B6F. [Also in Division G4] A printing apparatus comprises a number of type-wheels 19, each repeatedly movable to a selected position wherein for each print operation the position of each wheel is compared with the position of the next required character to determine the additional rotary movement required. As described, the apparatus comprises one hundred and twenty type-wheels 19, each of which is controlled by two memories, e.g. magnetic cores. The first of these memories (A) contains data for the line being printed whereas the sound (B) controls magnets 10 which determine which of the twelve sections of the type-wheel is required (see Fig. 2). At the same time as magnets 10 are being set, so are the magnets 20. These control the moment at which a cam 23 is rotated and this engages a boss 27 causing the type-wheel to swing and effect impression. The time of operation determines which of the four characters in the section is printed and the effect of swinging slows down the rotation of the type-wheel so a clear impression is made. When the control of magnets 10, 20 has been effected, the memories A, B prepare for operations relating to the following line. This is done by the transfer of the content of memory A to memory B and the text of the new line is entered in A. Comparison of A and B is made so that new controls are applied to the magnets 10; only the additional rotation to the appropriate one of the twelve sections of the type-wheel is thereby necessary.

As described closure of a switch 40 energizes transistor switches 1A-8A and results in the data being read out unchanged. Closure of switch 41 sets all the output lines to their "1" state via diode switches 1B, 10B, 19B ... 64B. To rotate for example three places right, as well as switch 3RS being operated, simultaneously switch 5LS is operated. If the sign bit on line 0Y is "1" during an arithmetic right shift operation certain of the output conductors are set to their "1" states. This is effected by operating simultaneously, e.g. for a five bit arithmetic shift, switches 5RS and 5ARS so that output conductors 0X-4X are forced to their "1" state by a signal passing switches 4A, 13A, 22A, 31A, 40A.

Title: Improvements in methods of forming superficial diffusion alloys on metal pieces and especially refractory metal pieces
IPC: C23C10/60
Filed: 1954-12-20
Abstract: Chromizing of parts made from an alloy based on Fe and/or Ni and further containing a metal imparting refractory properties viz Cr, Mo, Co, Al, Ti, or Mn, is effected by a halide diffusion process followed by a reheating in a non-chromizing atmosphere to cause Cr introduced into piece to diffuse towards the inner layers.  After the chromizing step the halide vapours in the container can be condensed away from the parts so that the rediffusion step can be performed in the same container.  The parts preferably are heated before the condensation step to draw off any remnants of liquid or solid halide. The part may further be treated by quenching in an oxidizing bath and briefly heated in a fluorine containing reducing atmosphere at a temperature higher than that necessary to reduce the oxide layer but lower than that at which substantial metal diffusion will take place. The parts may be mechanically shaped before chromizing and then the chromium introduced to produce an alloy which could not have been worked to the shape of the part initially.  Before chromizing, any of the metals which form precipitates in the mass of the part can be oxidized out of the part by electro-thermal sodium scouring or sodium scouring or sodium hydride scouring.  Silicon may be introduced into the part during the treatment to prevent carbide precipitation.
