Title: Improvements in or relating to rice hulling machines
IPC: B02B3/04
Filed: 1961-11-09
Abstract: 952,668. Hulling rice. TOSHIHIKO SATAKE. Nov. 9, 1961 [Nov. 14, 1960; Nov. 15, 1960], No. 40230/61. Heading A2Q. A machine for hulling rice, Figs. 1 and 2, comprises a frame 10, a stationary roll 12 mounted on an axle 15 rotating in the frame and a displaceable roll 13 mounted on an axle 20 rotatably mounted on a lever arm 19 pivoted, at its lower end, to the base 16 of the frame and, at its lower end to a nut 34 engaging screw threads on one end of a shaft 30 rotatable by a pulley 26, through control mechanism comprising gears and clutch members in a casing 29, so as to move the roll 13 towards the roll 12 automatically, at a controlled speed to maintain a predetermined pressure on rice grains fed, from a hopper 38 into the nip between the rolls and thus compensate for the wearing down of the abradable surfaces of the rolls. A spring 37 urges the roll 13 towards the roll 12, but the control mechanism prevents approach closer than a desired limiting distance and, moreover, stops the approaching movement if an excessive amount of unhulled grain or obstructing foreign matter tends to choke the machine. The rolls are rotatable in opposite directions by a driven belt 27 engaging pulleys 21 and 22 on the parallel axles 15 and 20. This belt also drives the pulley 26 and is tensioned by a pulley 28. The roll 13 may also be moved away from or towards the roll 12 by manual rotation of a wheel or handle 50. The roll 13 and lever arm may be moved by fluid-operated mechanism comprising a cylinder and piston actuated by the pressure of water or oil supplied by a pump driven by the belt or by compressed air from a compressor driven likewise.

Title: Improvements in or relating to devices for withdrawing sewn material from sewing machines
IPC: D05B33/02
Filed: 1966-09-09
Abstract: 1,096,963. Delivering sheets. G. M. PFAFF A.G. Sept. 9, 1966 [Oct. 25, 1965], No. 40289/66. Heading B6H. [Also in Division D1] In a device for withdrawing sewn material from a sewing machine, a guide finger, mounted on a carriage displaceable with an endless conveyer, is adapted for displacement relatively to said carriage between positions into and out of seating contact with the sewn material and, during the withdrawal of the material, is rotatable relatively to said carriage about an axis which is generally perpendicular to the material. A frame 3, fixed to a table 1 supporting a sewing machine 37, carries a pair of parallel bars 6, 7 slidably supporting a carriage 8. A hollow shaft 16, vertically slidable in carriage 8, is rigid with a block 15 slidably engaged with a vertical rod 17 rigid with carriage 8. A block 13 is pivoted at 14 to block 15 and is fixed to an endless belt 12 supported by pulleys 5, 11 journalled on frame 3. A shaft 18, journalled in shaft 16, carries at its lower end a workengaging foot 19 and is supported at its upper end in a U-shaped bracket 26 rigid with shaft 16. A bar 20, rigid with shaft 18 between the arms of bracket 26, carries at one end a rod 21 having a downturned free end, and is formed at its other end with an abutment surface 23. A torsion spring 27 biases surface 23 towards a pin 24 adjustably secured in an arcuate slot 25 formed in the upper arm of bracket 26 concentric with shaft 18. A spring 28 biases shaft 18 downwards. The arrangement is such that a motor 4 drives pulley 5 clockwise until block 15 is positioned above pulley 11, when a cam 29 on carriage 8 engages a roller 30 to open a switch 32 for stopping motor 4. Raising of the presser foot 38 of the sewing machine at the completion of the next workpiece 33 is arranged to start motor 4, whereby block 15 descends to engage foot 19 with the workpiece 33 and rod 21 with the angled end of a guide rail 22. Foot 19 thereafter shifts workpiece 33 in thedirection F, while rod 21 co-operates with rail 22 to turn foot 19 and the workpiece till a longitudinal edge of the latter is parallel with the rear edge of table 1. The workpiece thereby finally falls into a receptacle 36 positioned at said edge, and motor 4 continues to operate until cam 29 re-engages roller 30. The amount of turning imparted to the workpiece is determined by the conformation of guide rail 22, pin 24 being adjusted to insure initial engagement of rod 21 with rail 22.

Abstract: 1,094,158. Locks. YALE & TOWNE Inc. Oct. 13, 1964 [Oct. 17, 1963], No. 41013/63. Heading E2A. A door fastener comprises a pair of co-axial key-operable pin tumbler lock mechanisms 17 for actuation from opposite sides of the fastening, a housing 10 in which a bolt 14 is mounted for sliding movement, a lever 23 pivotally mounted at 22 in the housing 10, and means interconnecting the lever 23 with the bolt whereby angular movement of the lever will impart sliding movement to the bolt, the lever having an aperture accommodating a cam 18 actuable by both of the lock mechanisms, the aperture having edges for co-acting with the cam whereby actuation of either lock mechanism will impart movement to the bolt between its "shot" and "withdrawn" positions. As shown an L-shaped bolt lath 15 is secured to the bolt 14 and is connected to the lever 23 by a pin and slot connection 24. The fastening also includes a dead-locking lever 27 pivoted on a guide post 16 for the lath 15. Anticlockwise rotation of the cam 18 from the position of Fig. 1 by a key inserted in the lock mechanism first causes the lever 23 to pivot and the bolt 14 to slide to its "shot" position and then causes pivoting of the lever 27 so that a projection 27a thereon engages a shoulder on the bolt to dead-lock it. At the same time a tongue 27b on the lever 27 enters a recess 19 in the lock mechanism 17 to assist in preventing its removal from the housing. Rotation of the cam clockwise first releases the projection 27a from the shoulder on the bolt and then causes sliding of the bolt to its "withdrawn" position. The cam 18 then pivots the lever 27 further so that a pin 28 thereon engages a recess in the bolt lath 15 to dead-lock the bolt in this position. The lock mechanism 17 is also secured in the housing 10 by a screw 21 inserted from the edge of the fastening.

Abstract: 1,204,060. Mechanized storage installations. SIMON HANDLING ENGS. Ltd. 27 Aug., 1969 [29 Aug., 1968], No. 41280/68. Headings B8E and B8H. Transporting and stacking means 11 adapted to pick up unit loads such as palletized goods and automatically stack or store them at predetermined positions comprises position sensing means 10 co-operating with fixed markers 12. When the transporting and stacking means 11 is not loaded the position sensing means 10 is held centred on a slideway S by resilient elements 15 engaging pivoted lever arms 14 which abut stops 17. Owing to the working tolerance of the position sensing means 10 the transporting and stacking means 11 is not normally centred to the load to be picked up, but the action of the lever arms 14 is to centre the position sensing means 10 to the load as it is transported, so that the transporting and stacking means 11 will stop at a position related to the load irrespective of the relative position of the transporting and stacking means 11. A dashpot 16 damps undesirable oscillatory movement of the position sensing means 11.

The second layer may contain a blowing agent. When making the interlining the fleece, which may be consolidated by sewing, may be first impregnated with a temporary binder which is washed out after the first or both of the heat-weldable adhesives have been applied. Suitable temporary binders are carboxymethyl cellulose, starch, gelatin, methyl cellulose, polyvinyl alcohol, polyacrylic acid amides, and acrylic and methacrylic acid polymers. The permanent binder, which may be applied as a dispersion as temporary binder incompletely washed out of the fleece, may comprise p.v.c., polyvinyl acetate, polyvinyl lactylate, polyvinyl methacrylate, butadiene styrene copolymer, natural latex, or butadiene/acrylonitrile copolymer. Alternatively, a thermoplastic powder may be sprinkled on the rear of the fleece. As well as binder, the fleece may contain bicomponent weldable fibres, or lower-melting-point thermoplastic fibres, or thermoplastic powder, which fuse on heat-welding to alter feel, providing in toto the additions do not contribute more than 10% of the strength of the fleece. The first adhesive layer may be applied as a paste by screen printing, and contains, as adhesive, polyamides, linear polyesters, p.v.c., polyethylene, or saponified ethylene/vinyl acetate copolymer, which may be cross-linked, or may be applied as a p.v.c. plastisol. A suspension of the adhesive of the second layer may be applied by squeegee or roller, or by dipping the tips of the pattern or raster of the first layer into a thin film of the second adhesive. The second adhesive may be of the same material as the first with the proviso that its melting point was lower or made lower with suitable additives. A detailed Example is given wherein the fleece is formed of a straight and curly polyamide-6 fibres and rayon staple fibres, the second adhesive coating containing a blowing agent and an optical brightener.

Abstract: 1299860 Endless conveyers SPOONER FOOD MACHINERY ENG CO Ltd 18 May 1970 [17 May 1969 23 Aug 1969] 25261/69 and 42128/69 Heading B8A A row of articles on a pair of laterally adjacent endless conveyers 10, 11 is converted into two streams on the respective conveyer by a wall 20 extending at an angle across each conveyer and having an opening 23 mid-way along its length such that articles which engage the wall upstream of the opening are deflected into a stream 25 and articles which engage the wall downstream of the opening are deflected into a stream 24. The opening 23 may be closed by a gate 26 to deflect all the articles into the stream 24, such articles may however be deflected by a further gate 27 into the stream 25. In the latter cases where the articles are deflected into a single stream, the speed of the conveyer is doubled. A vertically movable alignment bar 18 is situated upstream of the walls. In a further embodiment, Fig. 3 (not shown), a pair of intersecting walls (48a), (48b) extend across both conveyers (40,)(41), the upstream portions (49a), (49b), of each being independently pivotable between an operative position and an inoperative position. When one upstream wall is in its operative position (the other being in its raised inoperative position), the operative wall is in alignment with the downstream portion on the other conveyer, so as to deflect the articles of the two conveyers into one stream on the other conveyer. When both upstream walls are in the inoperative position the articles pass therebeneath to engage the downstream wall portions (50a), (50b) to form a stream (54a), (54b) on each conveyer. A freely rotatable roller (52) is located between and tangentially with the conveyers at the apex (51) of the walls to assist in the transfer of articles between the conveyers. A control system doubles the speed of the conveyers when an upstream portion of a wall is operational to deflect all the articles on to one conveyer.
