Title: An improved method of grinding or disintegrating ores or other materials
IPC: B02C17/02
Filed: 1919-04-29
Abstract: 148,637. Hardinge, H. W. April 29, 1919. Ball and like mills.-In conical tube mills for grinding ores &c. and of the kind having grinding- bodies of varying size which arrange themselves at varying distances from the apex of the mill, the material is fed into the mill at substantially the point of greatest diameter where the greatest grinding effect occurs, and the ground material can escape through perforations at any point in the length of the mill. The material is introduced at the point 10 and, when sufficiently ground, can pass through perforations 13 at any part of the mill so that the cushioning effect of the finely-ground material is avoided. The mill has a replaceable, lining 18 having perforations corresponding with those in the mill wall, or the lining may have relatively large holes or longitudinal and transverse slots.

Title: Improvements in or relating to wood treatment
IPC: B27K3/15
Filed: 1959-03-26
Abstract: 905,061. Treating wood; proofing against fire and fungi. KOPPERS CO. Inc. March 26, 1959 [April 1, 1958], No. 10658/59. Drawings to Specification. Class 140. The resistance of wood to fire, fungi and dimensional change is increased without loss of impact strength by impregnation with an aqueous solution containing between 10 and 25% by combined weight of dicyandiamide and ortho-phosphoric acid in a mol. ratio of from 1: 1 to 3 : 1, and heating to a final temperature between 70 and 100‹ C. The aqueous solution may be pre-reacted (to form guanylurea phosphate) at a temperature of 80-100‹ C. before the impregnation. It is stated that such prereacted solutions give better retention in the wood than do solutions of preformed guanylurea phosphate. Both the pre-reacted solutions and the unreacted solutions react with the cellulose of the wood during the curing step. The solution may also contain chromated copper arsenate, chromated zinc arsenate, or chromated zinc chloride. The wood may be impregnated by applying first vacuum and then pressure while it is immersed in the solution, or by other standard processes. Specification 649,642 is referred to.

Title: Improved parking building for vehicles
IPC: E04H6/24
Filed: 1962-03-20
Abstract: 946,854. Multi-storey garages. F. J. BAUME. March 20, 1962, No. 10727/62. Headings B8A, B8E and B8H. [Also in Division F2] A mechanical garage consists of a central vertical latchway 16 flanked by superimposed facing pairs 12, 14 of parking stalls, each stall having an associated vehicle-carrying platform 22 connected thereto by an individual set of chains 40 to 43 by which it may be hauled up the hatchway 16 and directly into the stall. Within each stall the chains run in guides which prevent their flexing so that they may be used to push the platform out, assisted if desired by slightly sloping the stalls downwardly toward the central hatchway. Within the hatchway at each floor are a pair of tiltable chain guides 94 whose orientations are varied according to whether a left-hand stall 12 or right-hand stall 14 is being loaded or unloaded. Garage lifts.-The set of chains attached to each platform are connected (see Fig. 12) two to each longitudinal side of the platform 22 and pass over guide pulleys 71 to 74, Fig. 5, and thence with the horizontal guideways of the associated stall, in which the chains pass over individual sprockets on a common drive shaft 60, Fig. 1, to terminate at 80 in a spare-chain housing chamber 59. Conveyers.-In the horizontal movement between the shaft 16 and a parking stall 12, Fig. 1, the leftward parking movement is effected by a direct pull on the chains and the rightward de-parking movement by reverse drive of the chains, the guides 82 and 83, Fig. 5, in which they ran so closely embracing them that they function as pushing elements. These guides are arranged as shown in Fig. 4 just above the support rails 92 for the platform wheels 46, 47. Storage systems.-The garage of Fig. 1 consists of a plurality of separately constructed superimposed units each comprising a pair of facing stalls 12, 14 and an intervening hatchway section 16. Each stall is equipped with its own platform and associated drive means and each latchway section with the appropriate guide means. In use one of the platforms of the system is lowered to an entrance at the bottom of the hatchway and when loaded is returned to its stall. As the platform enters a stall 12, its trailing pair of wheels strike the lever 120 of the left-hand side, Fig. 5, to pivot a bridging member 88 into a position corresponding to that shown on the right-hand side of the Figure. At the same time the leading pair of wheels operates a lever which tilts the guide section 94 into the position appropriate to the use of the opposite stall 14. Thus when one stall is loaded the guide 94 is set for the use of the opposite stall and when both the platforms at a given storey are in their stalls, the associated bridge members 88 are both clear of the vertical chain guides 67, 69 so that the other storeys are all accessible.

Title: Procedure for temporarily attaching a pressure plate to a heater plate
Inventor: FROHNING HANS
IPC: B29C43/00
Filed: 1970-03-06
Abstract: 1,240,803. Laminating presses; hydraulic pressures. TH. GOLDSCHMIDT A.G. 6 March, 1970 [15 July, 1969; 21 Oct., 1969], No. 11004/70. Headings B5F and B5N. A pressure plate is temporarily attached to the heater plate of a laminating press by introducing between them a substance which is liquid or flowable under the press operational conditions and capable of exerting sufficient adhesion to maintain the pressure plate in position. If a cushioning pad is used between the heater plate and pressure plate, adhesive interlayers are used between the cushion and each of these plates. The attachment is achieved by assembling a lay-up of pressure plates, cushion pads (if used) and adhesive substances between the heater plates, with a protective board between the pressure plates, and actuating the press to adhere the pressure plates to the heater plates; the press is then ready for use. The pressure plates are removed by pulling off, optionally after cooling. The adhesive substance may be introduced as one or more thermoplastic films (polycarbonate, polymethyl methacrylate; polystyrene and polyethylene being used in examples), or may comprise silicone oil or, for use above 160 C., sulphur. Adhesion may be influenced by the use of softeners and separating agents or by roughening of surfaces. Heat conduction is improved by incorporating aluminium powder or graphite.

Patent GB-742074-A (GB)
Title: Improved method of generating compound master formers for use in controlling machine tools
IPC: B24B17/02
Filed: 1953-04-22
Abstract: 742,074. Copy-milling, planing and turning. GHAYE, A. L. J. April 14, 1954 [April 22, 1953], No. 11078/53. Class 83 (3). [Also in Group XXIII] A method of producing a master former for use in machining a turbine blade &c. consists in turning, milling, grinding or planing a blank employing an enlarged image of the blade as a pattern, a follower representing an enlargement of the tool to be used and a cutter representing the follower to be used in the machine for cutting the final turbine blade &c. The pattern 4 and the blank 7 for the former are mounted on opposite ends of a shaft 15 rotated by a motor, which also rotates a screw 27 through gears 29-33. The gear 32 may be rocked out of engagement to allow the screw 27 to be rotated by a hand wheel 37. The screw 27 moves a carriage 25 carrying a longitudinally-adjustable slide 38. The slide 38 carries a slideway 44 and a two-part slide 47, 48 on which is mounted the cutter 6 rotated by a motor 50, the two parts being relatively adjustable for depth of cut. The follower 1 is mounted on a slide 41 on a bracket 39 of the slide 38, and is held against the pattern 4 by hydraulic means 43. The movement of the follower is transmitted to the cutter 6 by a sine bar or grooved plate 9a engaged by a roller 12 on a vertical slide 52 having a similar groove engaged by a roller on a slide 54 having a third groove 11 engaged by a roller 14 on the cutter slide 47. Thus, the ratio of reproduction is determined by the various angles of the grooves. The slides containing the grooves may be adjustable to vary the groove angles or may be replaceable. In a modification, the rotary tool and follower are replaced by a point tool 58, Fig. 8, and an appropriate follower 57, and instead of rotating the work and traversing the tool-slide, the work is advanced intermittently by a ratchet-drive 20 driven by an adjustable crank 78 and the tool-slide 63 is reciprocated by a crank 72. Both cranks are driven by a motor 66. Movement of the follower, is again transmitted to the tool in a reduced ratio by three sine bars and followers 86, 89, 92. To prevent the follower 57 becoming interlocked with the pattern 4 it may be necessary to provide a controlled angular adjustment of the follower arm. The sine plates may be replaced by rack-and-pinion gearing. The pattern 4 may be enlarged axially, and appropriate reducing means be applied to the movement of the tool. Alternatively, the blank may be moved axially instead of the tool or the radial movements may be imparted to it. In a further modification, the follower may trace round drawings or shadows of successive cross-sections of the required shape. The Provisional Specification states that several successive contours may be produced around the periphery of a former to enable two or more work-pieces to be produced in a single revolution of the former. Specification 544,203 also is referred to.
