Filed: 1966-01-25
Abstract: 1,110,732. Mould closure apparatus. R. J. NAULT. 25 Jan., 1966, No. 3292/66. Heading B5A. Mould closing apparatus for a blow-moulding machine comprises a frame (10, 12, 32, Fig. 1), a pair of tie rods (13, 14) which slide in the frame, a push bar (16) fixed to and between the tie rods, a platen (22) fixed on and movable with the tie rods, another platen (18) slidably mounted thereon, the platens carrying the mould halves, power means (e.g. hydraulic cylinder, 26) to move the platens together and motion equalizing means comprising an idle pulley (46), having a flexible member (e.g. chain 40) trained over it, fixed to push bar (16) at one end and to platen (18) at the other by means of bar (52). Hydraulic piston (26) is operated to move platen (18) and push bar (16) apart. This will move platen (22) towards platen (18) since platen (22) is fixed to the tie rods (13, 14) to which push-bar (16) is also fixed. The platens will move together an equal amount due to the " equalizing means ".

Abstract: 1,142,096. Cutting silage. VSESOJUZNY NAUCHND - ISSLEDOVATELSKY INSTITUT SELSKOKHOZYAISTVENNOGO MASHINOSTROENIA. 23 Jan., 1967, No. 3336/67. Heading A4C. A drum shredder for cutting organic pulp, e.g. silage, peat, dung, comprises a rotary drum carrying knives 6 whose cutting edges are at least partially inclined at an obtuse angle to the direction of movement of the cutting means so that a slicing effect is obtained between the cutting means and the organic pulp cut. An ejector 7, Fig. 2, is associated with the knives 6. As described, the shredder comprises cylinders 1, 2 on a shaft 3, with a gear box 4 and boom 5. The knives 6 are helically disposed around the cylinders 1, 2 together with L-shaped blades 7. Each knife is formed as a plate having a lower flat portion 10, Fig. 4, and an upper portion 11, with sharpened cutting edge 12. Knives 14, 15 on the outer ends of the cylinders cut the material at the outer sides of the cylinders. An auxiliary rotary knife 25 cuts the material in the space between the cylinders 1, 2. The apparatus is driven from the power take off shaft 19, Fig. 5, of a tractor 20, and the boom is raised by an hydraulic piston/cylinder device 27. A receiving chamber 28 with a screw pick-up 29 and a thrower 30 with a charging pipe 31 is fixed on the frame 26 of the loader. A curved casing 32 on the boom prevents scattering of the cut material.

Title: Improvements in and relating to internal combustion engines of the rotary valve type
IPC: F01L7/16
Filed: 1938-02-03
Abstract: 510,603. Valves ; lubricating. ETESSAM, A. Feb. 3, 1938, No. 3339. [Classes 7 (ii) and 7 (vi)] In rotary valves of the kind which are held to their seating by pressure caused by the engine operation and transmitted through a column of liquid, means are provided for isolating the source of pressure from the column of liquid during pre-determined periods when the cylinder pressure is comparatively high. Fig. 1 shows a rotary exhaust valve 1 pressed against its seating in the neighbourhood of the cylinder port 13 by one or more pistons 8 to which oil or other liquid under pressure is supplied by a pump driven by the engine. The liquid acting on the sealing-piston is isolated from the pump supplying same, when the cylinder pressures are high, by cut-off valves 19, Fig. 6, having a passage 20 adapted to connect a supply passage 17 to passages 16 leading to .the sealing-pistons 21a, and to cut off the same when the valves 19 are pressed outwards by cams 21 formed on the rotary valve 1. The valves 19 may also press against springs 26 which operate levers 25 bearing on the pistons 21a. In this form, Fig. 6, the pistons 21a are fixed and the sealing-liquid presses the upper half 22, 23 of the valve housing on to the valve. The fulcrum of the lever 25 may be varied by moving an arm 27 along a slot 28, and this arm may be connected to the throttle. A light spring 11 maintains the piston 8 pressing on the valve while the engine is being started up. The valve 1 rotates between a stationary core 4 and the housing 2, and a similar valve 5 is provided for inlet. The boss 9 containing the piston 8 is separated from the water jacket 14 to allow free expansion, the water chamber being sealed by packing 15. Similar means for providing free expansion may be provided at the ends of the valve. Means are also described for cutting off the supply of lubricating-oil to passages in the valve when the valve port is passing the oil-supply duct, and a scraper on the valve housing removes surplus oil from the valve.

Class 125 (2) Bottle caps Y, of the kind having a divided skirt contracted about the bottle neck by the depression of a lever engaging a wire passing  through curled portions of the skirt sections, are held in a shoot 11 by abutments 20, 21 carried on horizontal levers 22, 23 pivoted at 24, 25 to the machine frame 10 and moved apart by an approaching bottle X engaging further abutments 26, 27 on the levers, the released cap being drawn out of shoot 11 by the bottle neck as it advances. The abutment 20 engages the cap lever which projects through a slot in the top plate 17 of the shoot. t. Abutment 21 engages the lowest point of the cap skirt. Levers 22, 23 are joined by a tension spring 28 and their approach is limited by adjustable stops 29. The bottle with its cap passes under a roller 33 pressed downwardly by a spring 35 on the shoot 11. An extension 17b of the plate 17 keeps the cap in place as the bottle moves to the cap-securing device described in Specification 701,525 which includes a pressure wheel 12 and a device for turning down the cap lever.

Title: Improvements in and relating to quick release connectors
IPC: H01R13/635
Filed: 1963-01-28
Abstract: 997,445. Stud and socket fastenings. F. G. BAC. Jan. 28, 1963 [Feb. 1, 1962], No. 3409/63. Heading E2B. [Also in Division H2] A pin and socket electrical connector which may be of bayonet type is adapted to be quickly released by sliding a locking collar surrounding a rotatable sleeve on one part of the connector and having internal diameters such that, when the locking collar is maintained in its normal position, it locks the coupling elements in the sleeve in engagement with a mating element in the other part of the connector whereas, when the locking collar is moved longitudinally the coupling elements may move radially outwards so that the connector parts can then be readily separated by a longitudinal pull. In Fig. 1 the locking collar 14 has two steps, one of which 14a locks balls 13 supported in sleeve 18 into a corresponding number of mating helical grooves 4 located on the outer surface of the plug 1, 2 when in its unstrained state, and the other of which 14b allows the balls to disengage from the grooves when the locking sleeve is strained so that the step 14b is aligned with the ball. The plug and socket parts are connected by the application of a bayonet type action so that the balls, held in their projecting position by the smaller step of the locking collar, engage the grooves. The plug and socket may be disconnected by applying this process in reverse instead of by the usual quick release action. In Fig. 4 a pin 46 co-operates with a groove 34 in bayonet fashion and release of the connector may be effected by drawing the collar 44 to the right by means of a cord 60. In so doing, the projection 54 engages a heel 51a of a lever 51 causing its left hand side to raise a pin 53 and thus the locking pin 46.

Title: A translucent material impermeable to ultra-violet rays and a process for the production thereof
IPC: C08J7/06
Filed: 1936-02-07
Abstract: Transparent or translucent papers, cellulose hydrate or cellulose derivative foils or like materials are rendered impermeable to ultra-violet rays by saturating them with a diluted aqueous solution of pine bark extract or quebracho extract.  The materials thus treated may then be freed from colouring and tanning constituents by washing.  The active substances giving resistance to ultra-violet rays are irreversibly incorporated in the paper and are not dissolved out by washing.  The extracts are obtained by treating crushed pine bark or quebracho with cold or hot water if desired under pressure in extracting or diffusion apparatus.  The extracts may be concentrated by evaporation and then diluted to the required strength.  If desired, a mixture of pine bark and quebracho extract may be used, and the proportions of the ingredients may be such that the treated material has a white fluorescence.  Pine bark extract gives a violet fluorescence and quebracho gives a yellow fluorescence.  Foils of cellulose acetate or other cellulose ester may be treated.  In the case of parchmentlike papers, the extract solution may be added to the paper material in the beating engine.  The treated material may be used for wrapping purposes.  The foils may also be used as ultra-violet ray filters in photography, or for making goggles.
