Title: Dismountable mould, particularly for the manufacture of building stones from porous concrete
IPC: B28B11/14
Filed: 1953-12-07
Abstract: 744,725. Moulds for casting concrete. DUROX INTERNATIONAL SOC. ANON. Dec. 7, 1953 [Dec. 9, 1952], No. 34029/53. Class 87 (2). Concrete blocks are cast in a mould with a loose bottom and in which a supporting band along the edges of the side walls or the bottom forms a groove for receiving lubricant to seal the gap between the walls and the bottom. With the bottom 3 resting on the supporting band 2 the concrete mixture is poured into the mould up to the correct level and the mould is moved to a curing chamber, where the material partially sets and fills the mould. The mould is then conveyed on a belt 7 to below a cutting device 8 comprising saw wires or cutting blades and vertically-guided lifters 9 rise to engage holes in bracing girders 4 on the bottom 3, which it lifts so that the concrete is cut into sections, the walls 1 remaining stationary. To assist the moulded block to leave the walls they slope slightly outwards and to ensure that they do not rise with the concrete, stops 10 are interposed. The bottom is then lowered again and the mould containing the cut concrete is conveyed to the hardening station. The supporting band 2 is so shaped that a groove is left between it and the wall 1 into which oil, introduced before the casting operation, runs off the walls of the mould and forms a. seal. In a modification, Fig. 5, the mould walls 13 rest on an angle-iron 12 welded round the edge of the bottom 11 and they are sloped inwards slightly. The oil seal is then in the space between the walls 13 and the edges of the bottom 11 and an additional outside rubber packing 19, Fig. 6, is fitted. When lifters 16 rise they engage brackets 15 projecting from the lower edges of the walls which therefore rise and leave the concrete on the bottom 11, which may be transported on a carriage 14. Brackets 17 also project from the upper edges of the walls, by means of which the walls may be conveyed away in a lifting contrivance 18. The outside bottom edges of the walls may carry rubber packing.

Abstract: 1,263,607. Polyurethanes. FARBENFABRIKEN BAYER A.G. 10 July, 1969 [15 July, 1968], No. 34827/69. Headings C3G, C3P and C3R. Polyurethanes are prepared by reacting (a) polyisocyanate with (b) modified aliphatic polycarbonates which have been prepared by polymerization of one or more compounds which contain one or more polymerizable C=C bonds in the presence of one or more aliphatic polycarbonates which contain at least two OH groups and have a M.W. of 800 to 3000, and depending on the conditions the polymers which have been prepared in situ are suspended in the polycarbonates, in some cases as homopolymers or may be partly or completely dissolved in the polycarbonate or may be present partly or completely as graft polymers. The modified polycarbonate is suitably prepared by dissolving the polymerizable unsaturated compound in the polycarbonate, followed by polymerization with the addition of radical forming initiators or the monomer and the activator may be slowly added to the polycarbonate or the activator may be heated with the polycarbonate and the monomer added subsequently. Acrylonitrile and methyl-, ethyl- and butyl-acrylate are suitable monomers whilst the preferred polycarbonate is hexane - 1,6 - diol polycarbonate. Chain lengthening and/or cross-linking agents, e.g. glycols and diamines, may be included in the reaction mixture. In a typical example diphenylmethane-4,4'-diisocyanate is reacted with a polyhydroxy compound prepared by polymerizing hexane-1,6-diol polycarbonate and acrylonitrile in situ with azodiisobutyronitrile and 1,4-butane diol is added to the melt to complete the reaction.

The queue may be established on a first in, first out basis in which case two registers NR and AR are provided indicating the store address in which the next command to be queued is to be stored and the address in which next command to be withdrawn from the queue is stored respectively. Alternatively the queue may be last in, first out in which case only one register is provided to indicate the address at which the next command to be queued is to be stored, the next command to be withdrawn being taken from the preceding store address.

Title: Machines for Producing Helically- or Straight-Fluted Workpieces by Grinding

IPC: B24B19/02
Filed: 1967-08-02
Abstract: 1,199,176. Grinding. H. N. BRAUM, and P. KOGLER. 2 Aug., 1967 [3 Aug., 1966], No. 35577/67. Heading B3D. A machine for producing helically- or straightfluted workpieces (e.g. twist drills and screw taps) by grinding comprises a head 4 which carries rotary workpiece spindles 6 at least equal in number to the grinding operations required for the production of a workpiece and which is indexable about its centre axis to bring each of the workpiece spindles successively into working position for each of the grinding operations, a reciprocating slide 3 for the head, first and second grinding-wheels a, b for grinding the flutes and reliefs in the respective working positions, a third grinding-wheel c disposed at a lip-clearance angle and a point angle in the point-grinding position, means, such as a driving shaft 18 and cam disc 20, for feeding the slide to cause the grinding wheels to perform their respective grinding operations, the feed of the slide relative to the third grinding wheel being limited during the whole point grinding operation as by linkage 10-15 connected to the third grinding wheel slide 8. Link 15 is adjusted by a settable abutment 16 so as to be joined to the movement of the slide 3 by means of a bolt 17 at the moment the vertically disposed cutting edge of the workpiece engages the grinding- wheel c. A rod 14 transmits the movement of link 15 to an adjustment spindle 9 on the slide 8 via levers 10, 12 which are adjustable by a bolt 11 and a screw 13. At the end of the advance movement of the slide 3, the grinding-wheels a, b are lifted clear by cams 21, 22, Fig. 5 (not shown). The workpiece spindles 6 are driven by a shaft 2 connected by gearing 1 to the driving shaft 18. If desired, the grinding of large flutes can be divided over two working stations by using two grinding-wheels on a single shaft. For a two-flute workpiece, the advance stroke is repeated, the spindles being indexed through 180 degrees between the two strokes. In another embodiment, the cam disc 20 has three ascents (I, II and III), Fig. 6 (not shown), the first for rapid run-up of the slide 3, the second for the advance to grind the helical flute and relief and the third for slow advancement to produce the helical point grind. Screw taps having helical or straight flutes may also be produced, the straight flutes neing made by employing a helically-fluted shaft 2 instead of a straightfluted one to prevent the workpiece spindles from rotating as they are advanced.

Title: Improvements in and connected with tenoning machines
IPC: B27F1/06

Abstract: 430,099. Tenoning-machines. AUSTIN, F. B., 2, Abbots Road, East Ham, London. Dec. 19, 1933, No. 35711. [Class 145 (i)] A tenoning-machine is provided with a power-driven cutting device mounted in a holder and having a cutter arranged to cut or scribe the base or butt of the member upon which the tenon is formed to the approximate outline of the moulding formed on the member into which the tenon is to be fitted. A double-ended tenoning machine, Fig. 1, has feed beams 1, 2 to which are secured housings 3 carrying circular saws 4. Each housing 3 is mounted in a bracket 25, Fig. 5, by means of bolts 26 passing through slots 27 which permit adjustment of inclination, the bracket 25 being secured to the feed beam by bolts 23. The saw 4, Fig. 7, is secured by a nut 12 and boss plate 13 on a spindle 9 mounted in bearings 11 in a boss 10 of the housing 3, the spindle 9 carrying a gear wheel 16 engaged by a gear wheel 17 on a second shaft 21 rotated by a flexible shaft 20 ; the saw may be driven in any other convenient manner. The gear wheels 16, 17 form shrouds to prevent sawdust getting access to the bearings. The saws 4 operate on the work before or after the tenoning operation ; the latter removes the shaded portions 6a, Fig. 3 ; the saw 4 makes a cut 4<a> and the triangular portion 5<a> is removed by the action of horizontal rotary cutters 1<a>. The portion 5 of the tenoned work 6, as e.g. a transom, is then moulded by a suitable cutter to correspond with the moulding 7 on the jamb 8. The preliminary scribing lessens the amount of wood to be removed in the moulding operation, thus diminishing the risk of breaking away. The final moulding operation may be dispensed with, the end 5 of the transom being caused to conform to the moulding 7 by exerting pressure in assembling.
