Filed: 1955-03-15
Abstract: 765,157. Dressing abrasive wheels. GLEASON WORKS. March 15 1955, No. 7565/55. Class 60. [Also in Group XXIX] A dresser for an abrasive wheel W, Fig. 1, comprises a frame 20, a pair of tool carriers 24, 25 mounted on the frame for independent angular motion about a common axis 26 and for motion in unison along such axis, a cam carrier 45 mounted on the frame for motion parallel to the axis, means for effecting opposite parallel motions of the tool carriers and the cam carrier, and cam means 36, 41 fig. 3, on the carrier 45 and co-operating cam follower means 35, 39 on the tool carriers for effecting angular motions of the latter in time with their motion along the axis 26. One of the tool carriers 24, Fig. 4, is con-, nected by a dowel 31 with a shaft 32 free to rotate and move axially in frame 20 while the other tool carrier 25 is free to turn on the shaft 32. The carrier 24 has a tool T which dresses the tip and outer conical surface 21 of the wheel W, Fig. 2, while the carrier 25 has a tool T<SP>1</SP> which dresses the inner conical surface 22 and the outer tip surface of the wheel. In order to impart the required motion to the tools T, T<SP>1</SP>, a shaft 32 and cam carrier 45 are connected by a lever 54 mounted on a pivot 55 and provided with sliding block connections 56, 58, the cam carrier 45 being displaced vertically through a rack 66 and pinion 65 from a hydraulic piston 61 (see Group XXIX). The hydraulic system which supplies the piston 61 also supplies pressure to a pair of plunger 43, Fig. 3, to hold the cam followers 35 and 39 in contact with the cams 41, 36. When either of these followers is out of contact with the cam 36 or 41 the corresponding tool carrier 24 or 25 is held in a predetermined angular position by a follower 37 which rolls on a guideway 38. A telescoping guard 93, 94 and 98, 99 seals the mechanism. A modified construction is described in which each surface of the wheel W is dressed by a separate tool.

Title: Improvements relating to foundry moulding machines
IPC: B22C15/10
Filed: 1930-03-08
Abstract: 350,020. Moulding-machines. NEESHAM, J. B., 4, Kelvinside Gardens, Glasgow. March 8, 1930, No. 7611. [Class 83 (i).] A moulding machine is provided with means for compressing and jarring the sand simultaneously the pressure being independent of the jarring movements. The compressing head 23 is of wood and is connected to a plate 24 carried by rotatable rod 20 screwed, for adjustment in a piston 19 which can be moved down, against a spring 25, by fluid pressure. The cylinder 1 is carried by an arm which has a limited swing about a pillar 3 mounted on one of the bars 5 connecting mould table 6 to the jarring head 7. The position of the head 23 axially over the mould 52 is determined bv an adjustable stop 31 and its lowest position by a key 26 placed in one of a number of slots in the rod 20. Rotation of the head is prevented by a guide-rod 28. The head 7 is carried on a cylinder 8, sliding on a fixed plunger 9 and jarring on an impact ring 65a, Fig. 4, of the material known under the registered Trade Mark " Leatherite." The plunger 9 serves as a cylinder for a plunger 12 carrying adjustable arms 16 which can pass through slots in the table 6 to lift the mould off the pattern, lift of the table being prevented by spring-pressed catches 57 normally kept disengaged by rods 61 depending from the arms 16. The jarring cylinder 8 is automatically reciprocated by air or other fluid admitted by a valve 36, Fig. 3a, having a plunger 34 which reciprocates with the cylinder 8 as it is pressed by a spring 39 to engage its adjustable head 38 under a projection 40 thereof. A valve sleeve 35 is arranged on the plunger 34 and is pressed up by a spring 41. In the position shown air is admitted to the cylinder 8 by ports 44, 45, 46 but, when the plunger rises sufficiently, air is admitted by ports 48, 47 to the space above the sleeve 35 which is thus forced down closing the supply and opening the cylinder 8 to exhaust through ports 50, 51, 49. When the plunger 34 is moved down the space above the sleeve 35 is exhausted by ports 54, 55 and it resumes its original position, being cushioned by a buffer 42, and the cycle is repeated. The plunger 12 is raised by admitting air to a reservoir 77 containing oil which is forced through a passage 76, containing a regulating valve if desired, and a tapered passage 75 into the space below the plunger which thus rises with an accelerated speed. When the air pressure is released a valve 78 opens and the oil returns to the reservoir direct. Rotation of the cylinder 8 and plunger 12 is prevented by fixed guide-rods 70, Fig. 4, and an upper limit to their movement is determined by springs 74 and a rubber buffer 67. Guards and lubricating means may be provided.

Title: Method of welding a synthetic resin foam material
IPC: B29C65/00
Filed: 1974-02-19
Abstract: 1460845 Laminates T SAITO 19 Feb 1974 [20 Feb 1973 7 March 1973 13 March 1973 9 Oct 1973] 7615/74 Heading B5N [Also in Division B2] A sheet of synthetic resin foam material, e.g. polyurethane, nylon or a vinyl compound, is treated so as to render portions of the sheet weldable to a substrate, e.g. a polyvinyl chloride sheet or a reinforcing fabric by compressing the sheet so that the portions to be rendered weldable are not compressed, impregnating the uncompressed portions with a polymer solution, e.g. nylon or a vinyl compound, the polymer having a melting point lower than the synthetic foam and volatilizing the solvent. In an alternative method a mask having cutouts corresponding to those portions of the sheet which are to be rendered weldable to a substrate is placed in the foam sheet and a powder of a polymer having a melting point lower than that of the synthetic resin foam material is incorporated into the unmarked portions of the foam and heated to cause adherence to the foam. A sheet of foam may be mounted on a lower platen 10 and then an upper platen 14 is moved downwards to press the portions of the foam except the welding portions against the platen 10. Then a solution of welding material is supplied to liquid reserving grooves 11 through passages 13 and 12 to impregnate the weldable portions of the foam. In a modification of this apparatus, upper platen 24 is moved downward towards lower platen 20 to compress the foam member. During this movement manifold 31 is supported by piston rod 36 of unit 35. Welding solution is supplied to members 32 from manifold 31. After impregnation occurs welding material flows into grooves 31 through fine meshed members 30 to be returned to the source via discharge passages 22, 23. Also after impregnation, piston cylinder unit 35 is actuated to cause downward movement of manifold 31 so that tubular members 32 move downwards in slots 25 of platen 24 and fine meshed members 33 of members 32 and corresponding fine meshed members 30 in grooves 21 co-operate to apply a predetermined pressure to the welding portions 2 of foam member 1. Excess welding material flows via grooves 21 and passages 22 and 23 to the source. Subsequently the unit 35 is actuated to return manifold 31 to its upper position. The product when welded to a substrate may be used in furniture or as a wall covering.

Title: Diaphragm for screening roentgen rays
IPC: G21F1/10
Filed: 1951-04-06
Abstract: X-ray diaphragms having fine particles embedded in an insulating resin consist of lead powder and lead sulphate embedded in a resinous polyhydric phenol derivative containing at least two ethylene oxide groups.  In an example, 84 per cent lead powder, 9 per cent lead sulphate, and 7 per cent "Araldit" (Registered Trade Mark) resin (proportions by weight) are mixed at 120 DEG  C.  A hardening agent, e.g. phthalic acid, is added, and the mass is poured into a mould and hardened at about 120 DEG  C.  The lead grains are preferably 0.1-0.2 mm. in diameter.  Neutrons, which may be formed in the resin, are retarded by the resin, and may be absorbed by small quantities of elements such as boron or cadmium or their compounds added to the mixture.  The diaphragm, which is free from eddy currents and thus suitable for use with a betatron, may be worked after moulding, and may be made in several parts afterwards cemented together.  The density of screening material may vary from place to place in the diaphragm.
