Title: Method and apparatus for producing prefabricated structural members
IPC: B28B19/00
Filed: 1976-05-14
Abstract: For the production of prefabricated construction elements, a mixture containing 20 to 30 parts by weight of water to 100 parts by weight of gypsum anhydrite is filled into moulds. The mixture is under elevated injection pressure during injection into the moulds and the viscosity of the mixture is reduced by intense mixing and shearing forces and by a mixing pressure of above 8 atmospheres above atmospheric pressure. During the setting of the mixture in the mould, an elevated setting pressure is maintained in the mixture. A continuously operating mortar mixing machine is used for this. The latter is connected at its inlet side to a pressurised water line (4) and at its outlet side to a pressure pump (8). The pressure pump is connected to a filling nozzle. A high-speed worm building up a pressure of at least 8 atmospheres above atmospheric pressure is provided as a stirring element. <IMAGE>

Title: Improvements in and relating to electric discharge devices
IPC: B64B1/00
Filed: 1932-07-15
Abstract: 397,291. Thermionic cathodes. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. -(Assignees of Allgemeine Elektricitats- Ges. ; 2, Friedrich Karl-Ufer, Berlin.) July 15, 1932, No. 20097. Convention date, July 15, 1931. [Class 39 (i).] An indirectly-heated cathode consists of a metal open-ended tube 1 preferably of nickel, containing a compressed mixture 2 of an electron-emitting material and an initially non-coherent metal mass, preferably bariumoxide and tungsten powder. The heating element may be a spiral 5 wound on a quartz sheath 4. A nickel reflector 9 may be added. The cathode is supported on a lead 3, and the sheath and heater on the heater lead 6 and ring 8. The electronemitting mixture may be compressed into a cylinder of the same size as the interior of the nickel tube and may then be introduced at the open end. In a modification, a nickel cylinder of larger diameter than the final cathode is filled with the powdered mixture and is then drawn down to the required diameter, compressing the mixture. The tube is then cut into the required lengths. A nickel tube of internal diameter 2À4 mm. and wall thickness 0À3 mm. may be thus reduced to internal diameter 1À4 mm. and external diameter 1À9 mm.

Abstract: 238,549. Siemens & Halske Akt.-Ges. Aug. 18, 1924, [Convention date]. Automatic exchange systems. - To increase the efficiency of a group of trunks, the known grading arrangement shown in Fig. 1, in which in each of the switches I - - XII the trunks connected to the early positions 1 - - 4 are common to two switches and the later ones more and more widely available. those in positions 5 - - 8 being common to 6 switches and those in positions 9, 10 to the whole group, is modified as shown in Fig. 2, in which the availability both increases and decreases with the order of choice. The Specification discusses the principles on which the invention depends, and points out that for maximum efficiency, an increase in availability should be made suddenly, as in the case of positions 2 3, and a decrease gradually as in the case of positions 3 - - 6. The average availability of the first few positions is low and of the last few high.

Title: Improvements in and relating to the manufacture of printing screens
IPC: B41C1/14
Filed: 1950-08-18
Abstract: 704,148. Stencils. HLUBUCEK, J. Aug. 9, 1951 [Aug. 18, 1950], No. 20534/50. Class 100 (2) The manufacture of a printing screen comprises applying plasticized polyvinyl chloride in paste form in one or more coatings to the base material of the screen to be made, so as to form thereby those areas which are to be impermeable to the printing medium, and heating the applied coating or coatings to solidify the same to an elastomeric state. In one form, a temporary screen is prepared having a negative of the design, and the paste is applied through the permeable portions of the negative design on to the base material. The temporary screen is prepared photographically, using gelatine or polyvinyl alcohol, or by placing over one side of it a cut-out paper or like stencil of the design prepared, and applying by a squeegee a coating of the paste to the other side, whereupon the stencil temporarily adheres to the screen. The screen is stretched on a frame which is placed within a larger frame on which is stretched the material to form the final screen, the latter laid on a support such as a polished aluminium or other metal, or glass sheet, the paste applied through the temporary screen, and the coating heated. In another form, a cut-out or photographic positive of the design, such as a greaseproof paper stencil, is prepared and laid on a support, and over it a stretched silk-screen is placed and the paste applied. The paste passes on to the support in the permeable areas, while in the impermeable areas it causes the positive to adhere to the screen and remains in and on the screen. After heating, the positive is manually stripped off. The paste may comprise 40-60 parts by weight polyvinyl chloride polymer as a powder or in fine particles, 60-40 parts tricresyl phosphate or other plasticizer, the parts of polyvinyl chloride and plasticizer making a total of 100, and up to 30 parts of an inert filler, or 50 parts polyvinyl chloride, 50 parts tricresyl phosphate or other plasticizer, 1 part white lead, and 20 parts whiting, and is evenly spread with a rubber squeegee. Heat stabilizers, dyes, or pigments may be added. The coating is hardened by heating in an electric oven for two or three minutes to 155‹ C. Before heating, substances such as natural or synthetic resins, which are compatible with the printing uses to which the screen is to be put, may be added for toughening purposes. The screen material may be Indian silk of about 30 mesh, bolting silk, organdie, or metal gauze. If a thicker coating is required, a first coating is pre-gelled by heating to 100‹ C., after which a further coating can be applied, the whole then being cured at 155‹ C. The temporary screen can be washed out and used for a new design, or used repeatedly to prepare identical screens. If the final screen is to have a repeat design, a temporary screen of a single design unit may be used and the final screen built up by accurately registered steps, each step being pre-gelled at 100‹ C.

Abstract: 786,587. Variable throw cranks. HOLDENER, S. July 18, 1955 [Aug. 28, 1954], No. 20674/55. Class 80 (3). The throw of a crank-pin 6 eccentrically mounted on a shaft 5 housed in an eccentric bore in a driving shaft 1 is adjusted with respect to the rotating shaft 1 by axial displacement of a bolt 21 rotating concentrally with the shaft 1. The bolt 21 is coupled by a flange 20 to an internally- and externally-threaded member 14 movable coaxially with the shaft 5 within a head portion 9 of the shaft 1. The two threads on the member 14 are of steep pitch and of opposite hand, and engage respective threads on the shaft 5 and in the portion 9 so that axial displacement of the member 14 causes the shaft 5 to rotate relatively to the shaft 1 and thus varies the throw of the pin 6. The eccentricities of the bore in the shaft 1 and of the pin 6 relative to the shaft 5 are equal so that the throw of pin 6 may be adjusted from zero to an amount equal to twice said eccentricity. The rotating bolt 21 is axially moved by a fork (not shown) engaging the outer race of a bearing 26 thereon. The shaft 1 is driven through a chain-wheel 11 coupled thereto.
