Title: Improvements relating to the Production of Hollow Core and Shell Casting Moulds
IPC: B22C23/00
Filed: 1968-08-06
Abstract: 1,177,741. Moulding machine. CRONING & CO. 6 Aug., 1968 [30 May, 1968], No. 37483/68. Heading B3F. Apparatus for use in producing hollow core or shell casting moulds comprises a container 2 for finely-divided moulding material, and a feed pipe 1 through which the moulding material is delivered, by compressed air supplied to the container 2 through a conduit 15, to a hollow pattern 6, the feed pipe 1 being bodily movable relatively to the container 2 between a position in which the pipe is sealed from the mass of material in the container and a position in which the pipe is open to the material in the container. In its sealed position, the pipe 1 is held against a sealing plate 3 in in the base of the container 2 by a spring 10. Admission of compressed air through conduit 9 to the lower part of the cylinder 5 raises the piston 4 and thus the pipe 1 to which it is attached, thus allowing the moulding material to be forced along the pipe 1. On completion of the moulding operation, the pipe 1 is returned to its sealed position by feeding compressed air to the cylinder 5 through a conduit 8. To recharge the container 2, it is vented and compressed air fed to the cylinder 5 through the conduit 9. This causes the sealing plate 7 to move downwards and thus allows the moulding material collected above the plate 7 to pass into the container 2.

Abstract: 837,687. Cutting straw &c. GRONBERG, A.B. Nov. 21, 1958 [Nov. 22, 1957 ; Sept. 23, 1958], No. 37499/58. Class 5(1). Straw, green fodder &c. sucked up into a fancontaining casing 8 is cut between rotating knives 14 and interdigitated fixed knives 15. Any straw approaching the knives end-on is turned sideways by the action of a ridge 21 in the casing where the casing opens out to a cylindrical wall part 20. An adjustable angle damper 26 is provided in the stream to direct the straw against the ridge 21. The ridge 21 may be replaced by a more pronounced cutting ridge 33, Fig. 2 (not shown), and guide. In Fig. 3, 43 is the ridge of a shield 24 adjustable by a handle 38. Figs 4 and 5 (not shown) comprise other forms of adjustable shield and ridge. For cutting green fodder the knives 15 are removed to prevent the fodder from being cut too much and so become pasty.

Abstract: 898,399. Combined disc and band brakes. BENDIX CORPORATION. Nov. 25, 1958, No. 37969/58. Class 103 (1). A disc brake comprises a pair of discs 28, engageable with spaced flat surfaces of a casing 10, 12 14 by cam means interposed between a disc member 38 and each of discs 28 upon a slight angular movement between discs 28 and member 38 when a brake band engages the periphery of the member 38 or discs 28. The brake band 62, 63 is tightened on to the rim 60 of member 38 causing balls or rollers 48 to move into the shallower parts of complimentary conical recesses 44, 34 in member 38 and discs 28 respectively, to axially move the discs 28, splined to shaft 20, against the fixed casing 10, 12, 14. The discs 28 are biased to the release position by springs 50 and are prevented from relative rotation by pins 52 which pass through slots 54 in member 38 to permit limited rotation of member 38 relative to discs 28, the pins 52 and split rings 42 in grooves 26 in shaft 20, supporting the member 38 clear of the shaft. The recesses 34, 44 may be formed in the discs 28 and member 38 or in hardened inserts 36, 46 respectively. The ends of the band 62, 63 are pivoted to actuating toggle linkage 72, 78, 82, 88 by pins 64 carried by shanks 94 screwed into sleeves 98 slidably mounted in casing 14, the outward movement being limited by a head 100 and spring washers 102. On actuation, the band moves with member 38 until one head 100 abuts casing 14, the outward movement of the applying linkage being transmitted to the opposite band and, the corresponding sleeve 98 sliding inwardly of the casing. A lock-nut 96 on the shank 94 is used to adjust the band clearance of rim 60.

Abstract: 621,770. EIectromagnetic switches. ELECTRO METHODS, Ltd., BUTCHER, F. E., and WALDSCHMIDT, F. Dec. 31, 1946, No. 38100. [Class 38(v)] A shock-proof relay or relay assembly has two moving contacts 12, 13 which move in opposite directions when the relay is energized but in the same direction under shock. In the form shown, energization of the coil 2 causes attraction of the two armatures 8, 9 and closing of contacts 12, 14 and 13, 15 arranged in series with one another. When de-energized shock could not cause simultaneous closing of these contact pairs. In a modification, Fig. 2 (not shown), the contacts pairs are normally closed and arranged in parallel so that shock would only open one pair and the circuit would remain closed.
