Inventor: HUGHES RODERICK FRED
IPC: B23B31/20
Filed: 1958-09-09
Abstract: 856,264. Chucks. OSBORN & CO. Ltd., S. Sept. 7, 1959 [Sept. 9, 1958], No. 28937/58. Class 83 (3). A chuck comprises a body 2 and a stop 4 formed on a collar 5, the latter having flats on its periphery which engage corresponding flats in the body 2 and on an internally-screwed sleeve 11 to prevent relative rotation of the stop and sleeve, the sleeve being moved axially of the body to actuate a collet 18 through a second sleeve 14. In operation, the shank 26 of a tool is screwed into the sleeve 11 until it abuts the stop 4. Further rotation moves the sleeve to the right, thus closing the collet by the second sleeve 18, the collet being held against outward axial movement by a nut 24.

Title: Self cleaning filter
IPC: B01D29/15
Filed: 1963-07-23
Abstract: As an inward-flow drum 16, Fig. 1 (not shown), is rotated, an endless stranded wire 44 is progressively unwound from, and re-wound in, a helical groove in the drum surface, by an idler pulley 42 which is free to rotate on and slide along a fixed shaft 32 (parallel to the drum axis), so as to permit removal of solids collected on the outside of the assembly.  A wiper shield 52 has a ridge 54, Fig. 2, (not shown) formed on it to engage the groove in the drum so as to be driven longitudinally thereby, and has pads or brushes to wipe the wire clean.  The ridge 54 also scrapes the groove clean.  Liquid enters the casing at 12 and leaves through hollow stub shaft 22 and casing opening 14.  The pulley 42 reverses the direction of rotation of the drum at each end of its travel by limit switches 50.  In a modification, Fig. 7 (not shown), the wiper shield is mounted on a threaded shaft which is positively driven by toothed gearing from the drum, and the idler pulley is freely mounted on one side of the wiper shield.

Abstract: 665.079. Resilient mountings. LORD MANUFACTURING CO. Nov. 15, 1949 [Feb. 21, 1949], No. 29228/49. Class 108(iii) A resilient mounting system for connecting supporting and supported members 7, 1 comprises two pairs of mounting units 2 which are all located on one side of the supported member 1, the principal axes (corresponding to the respective directions of maximum stiffness of the units) intersecting in pairs at spaced points on a common axis, and intersecting (when paired differently) at spaced points on a second common axis, spaced from, and normal to, the first axis. Axes 9, Fig. 1, normal to the plates 5, 6 of shear sandwich type rubber mounting units 2 (Fig. 4) intersect at two pairs of points A, A. and B. B to define axes 11, 12 which are spaced from each other and lie above the centre of gravity. The supported member 1 may be in the form of an angle-section frame (Fig. 6, not shown) which may be hinged down from an inoperative position and located by pins and clamps. The static load may be taken by a pair of coiled springs mounted between the supported and supporting members 1, 7. Adjacent each coiled spring may be positioned a friction damper (Fig. 9) comprising a bracket 39 lined with rubber and rigid with the member 7, and a rectangular-sided housing 31 rigid with the member 1. Discs 37 having hubs 36 mounted in a rubberlined tube 33, are urged by a spring 35 into frictional engagement with opposite walls of the housing 31. The damper operates only when the ampliture of vibrations exceeds the clearance between the tube 33 and rubber lining of the member 39. The shear sandwich mounting may be replaced by the coiled compression spring 48 ad rubber movement-limiting buffers 50, 51, In a modification Fig. 11 (not shown a tension spring is employed.

Title: Method  of heading spindleshaped fishes and a device for  implementation of this method
Inventor: DUTKIEWICZ D
IPC: A22C25/14
Filed: 1971-06-22
Abstract: 1341588 Beheading fish MORSKI INSTYTUT RYBACKI 22 June 1971 [13 July 1970] 29241/71 Heading A2U The position at which a cut is made for beheading a fish is determined by contactless measurement of the length of the fish. A fish to be beheaded is placed on a V-shaped trough defined by fixed and movable plates 1, 2, the head of the fish engaging a transverse plate 14 across the end of the trough. A cam 6 on a rotary camshaft 7 then operates a lever 4 which, through a spring-loaded tie 3, swings the lower edge of the plate 2 away from the plate 1 to allow the fish to drop into a second trough composed of plates 9, 10 hinged at their upper edges. The length of the fish is sensed by a photoelectric device comprising an arm 21 carrying a lamp 20 and photoelectric element 19 aligned with slots 11 in the plates 9, 10, the arm 21 being movable in a horizontal plane about a pivotal mounting and having a connection 22, 23 with an axially movable sleeve 24 connected with a rotary disc knife 26 so that deflections of the photoelectric device and of the knife bear a definite, adjustable relationship to each other. A cam (not shown) on the shaft 7 operates a microswitch (not shown) to energize either of a pair of couplings 30 which transmit rotary motion in opposite directions so that the sleeve 24 is displaced axially in one direction or the other through a rack 27 and pinion 28 on a shaft 29. The condition sensed by the photoelectric device determines which of the two couplings is energized, and the coupling is de-energized and a brake 31 applied when the photoelectric device senses the tail end of the fish. A cam 18 on the shaft 7 then causes a lever 15 carrying an adjustable thrust plate 16 to push the fish downwardly, a member 8 at the same time releasing the plates 9, 10 so that they can be pushed apart against spring loading by the descending fish, which is steadied by a plate 13 during the beheading operation. As the lever 15 retracts to its upper position in readiness for the next cycle it closes the plates 9, 10 through a member 17. The plates 9, 10 may be made of transparent material, thereby avoiding the necessity for the slots 11.
