Title: Improvements in or relating to punching apparatus
Filed: 1952-10-28
Abstract: 740,550. Selective punching machines. ADDRESSOGRAPH - MULTIGRAPH CORPORATION. Oct. 28, 1952 [Dec. 4, 1951], No. 27058/52. Class 31 (2). In a selective machine for producing business instruments having punched data-representing perforations therein and provided with a plurality of punches in each of a plurality of columns and with individually settable interposers for determining the punches to be actuated in the respective columns, means are provided which are operable while the interposers remain set in their selected positions to actuate selectively either all of the set interposers or only a selected number of the set interposers. The machine shown in Fig. 1 is adapted for producing business instruments which have a printed identifying impression formed thereon by means of a printing and control device and data-representing perforations formed therein by means of a punch unit controlled by the printing and control device. For example, the machine may produce a billtype card C, Fig. 7A, and a related accounting card C-1, Fig. 6A, the latter having datarepresenting perforations 107 which are not included in the card C. The cards C, C-1 are fed successively along a sheet gwideway SG, Fig. 1, by means of feed rollers 111, 112 and stopped successively at a punch unit PU and at a printing head 110 by means of a rocker 113 operated from a cam on a cam-shaft CS-2 through the intermediary of a lever 115. The rollers 111, 112 are raised and lowered at appropriate intervals by means of cams on the shaft CS-2. The punch unit comprises punches 127, Fig. 4, which are set by means of interposers 136, 136M set automatically and manually respectively. The interposers are operated to actuate the punches by means of a main ram plate 135 and a supplementary ram plate 135S disposed for endwise movement in a slot in the main ram plate. The latter plate has attached thereto blocks 166, 170, the block 166 having a flange 166D and a recess 166R and the block 170 having its left-hand edge overlying the edge of the slot in the main ram plate. The supplementary ram plate has ball-retained plates 151 attached thereto and is provided with a slot 165 near its left-hand edge. A spring 160 normally urges the supplementary ram plate upwardly and to the right, Fig. 5A, so that it will be moved downwardly on depression of the main ram plate. This is the position of the ram plates when the card C-1 is perforated. To prevent the perforations 107 being formed in the card C, the supplementary ram plate is moved to the left, Figs. 4 and 5, so that it will not be moved downwardly with the main ram plate, by means of a spring-influenced pawl 180, which engages the right-hand ball retainer block 151 on the supplementary ram plate, operated by means of an axially-adjustable cam roller 191 engaging a cam 193 on the shaft CS-2. Specification 740,535 is referred to.

Title: Protective cellulose hydrate foil
IPC: C09J7/35
Filed: 1934-09-20
Abstract: A protective foil for application to cards, pictures, maps, advertisements and similar articles comprises a foil of cellulose hydrate having a coating which becomes plastic and adhesive in the warm and which is composed of a cellulose derivative of low viscosity and a resin which retains the latter in solution in the warm, with or without plasticizers.  The coating layer should contain 30--60 per cent of cellulose derivative, 10--60 per cent of natural or synthetic resin and 15--50 per cent of plasticizer referred to the dry products.  If the resin is a solvent for the cellulose derivative in the liquid condition the plasticizer may be omitted.  With nitrocellulose of low viscosity, a mixture of ester resins and tricresyl-phosphate, or of polyvinyl acetate and dibutyl phthalate may be employed, while acetyl cellulose requires rather more plasticizer and cellulose ethers less.  The dissolved or melted coating layer is applied to one side of the foil by a lacquering machine or by brushing or spraying, and the foil may be applied by ironing with a warm iron.  The viscosity of the nitrocellulose employed should be 0,3--2 Poises at 18 DEG  C., when measured as a 10 per cent solution in butyl acetate, while organic esters or ethers in a 10 per cent solution should have a higher viscosity (up to 10 Poises).  The foil may be waterproofed with a lacquer coating prior to the application of the adhesive layer.ALSO:A protective foil for application to cards, pictures, maps, advertisements, and similar articles comprises a foil of cellulose hydrate having a coating which becomes plastic and adhesive in the warm and which is composed of a cellulose derivative of low viscosity and a resin which retains the latter in solution in the warm, with or without plasticizers.

Title: Process for preparating fluorosilanes
Inventor: FITCH FREDERICK TROOP
IPC: C07F7/16
Filed: 1956-09-11
Abstract: Fluorosilanes of the general formula RaSi ClbF(4-a-b), where R is an alkyl or aryl radical, a is 1 to 3, b is 0 to 2 and a + b is 1 to 3, are prepared by contacting a finely divided silicon metal-containing mass with silicon tetrafluoride and an alkyl or aryl chloride vapour at about 250-500 DEG  C., condensing the reaction products and separating the fluorosilanes.  The mol. ratio of chloride to SiF4 is preferably about 0.5 : 1 to 3 : 1.  The silicon mass may be ferrosilicon, an alloy with copper, or silicon promoted with metals such as nickel, cobalt, antimony or phosphorus.  In the example, a mixture of powdered silicon and cuprous chloride supported on glass wool is heated at 400 DEG  C. in a current of nitrogen, the cuprous chloride being reduced to copper.  The bed is allowed to cool to 300 DEG  C. and a mixture of methyl chloride and SiF4 is introduced, the temperature being raised to 327 DEG  C. in 12 hours.  The product is collected in dry ice-acetone traps and is fractionated. Methyltrifluorosilane is obtained together with chlorofluoromethylsilanes.

Abstract: 426,007. Regulating compression. GRESHAM & CRAVEN, Ltd., GRESHAM, J. N., and ARNOLD, C., Ordsall Lane, Salford. Oct. 10, 1933, No. 27862. [Class 8 (i)] [See also Group XXXIV] Vacuum or compressed air brakes comprise a train pipe b and a releasing pipe c which controls a clutch by which an auxiliary exhauster or compressor p is brought into operation on a change-speed gear by which the ordinary exhauster or compressor is speeded up, to effect rapid release of the brakes, the pipe c being exhausted from the train pipe b by a connection f containing a check valve g. The vehicle engine a drives the main exhauster m through a gearbox n. A governor o on the driving shaft v from the vehicle engine operates a cut-off valve u when the engine speed is above idling, which cuts off the pipe c from the clutchoperating diaphragm chamber t and connects the chamber below the diaphragm to a vacuum reservoir j. The chamber above the diaphragm is permanently connected to the reservoir j. When the brakes are applied pipes b, c are connected to atmosphere and when the brakes are released and the engine is idling, the increased pressure in the pipe c operates the actuator t which by means of an arm s engages the clutch to bring the auxiliary exhauster p into operation. The vacuum in the pipe c is restored only gradually through a restriction h until it is sufficient to operate the actuator t to declutch the exhauster p. The pipe c is provided with a capacity reservoir i through which the reservoir f is exhausted. A modification is shown in which the actuator t operates a change-speed gear to accelerate the main pump.
