Title: An improved method for picking and collecting hops
IPC: A01D46/02
Filed: 1938-07-08
Abstract: 516,822. Picking hops. McCONNEL HINDS, Ltd., HINDS, G. A., and McCONNEL, F. W. July 8, 1938, No. 20314. [Class 6 (iii)] In the picking of hops, a mixture of leaves, hop flower petals and seeds, with or without hop flowers, is carried over a sieve that will pass the seeds and petals only, and these seeds and petals are then mixed with the hop flowers which have been separated from the leaves and branches by other steps in the process. The bine is fed into a hop-picking machine by means of which the hop flowers and leaves are detached. Short branches which are torn off are passed through a machine whereby they are gripped by means of two sets of endless cords. The hops and leaves are loaded on to a conveyer 11, Fig. 1, and are fed to an open wire mesh belt 9. The belt allows petals and seeds to fall. with the help of an air current through a conduit 42, on to a transverse conveyer 35 which delivers to a bin 36. The leaves and flowers pass below the lower stretch of a similar conveyer 8 which forms the bottom wall of a vacuum chest 7. The leaves are held up by suction against the conveyer 8 while the flowers pass on the conveyer 9 to further conveyer 28. The leaves eventually fall on to an incline 24 and pass to a conveyer 25. If any petals or seeds remain they fall through the conveyer on to a transverse conveyer 35. In a modification shown in Fig. 3 hops and leaves are delivered to an inclined sieve 39 through which petals and seeds fall. The sieve is vibrated by means of a cam. The flowers and leaves pass below part of a rotary sieve disc 33 which closes the mouth of a vacuum chest 7. The leaves are drawn up by the suction and owing to the rotation of the disc are deposited on to conveyer 34 which is impervious. to air.

Title: Vehicle steering gear
IPC: B62D3/10
Filed: 1947-07-28
Abstract: 638,882. Vehicle steering gear. GEMMER MANUFACTURING CO. July 28, 1947, No. 20326. Convention date, May 28, 1941. [Class 80 (iii)] In a vehicle steering gear, the steering stem B carries a loose worm C which is geared to the steerable road wheels. A fixed ring F has a cylindrical bore into which project projections I, J, on the worm C and stem B respectively. Between the projections I, J, two rollers K<1>, K<2> are located with their line of centres slightly to one side of a diameter of the ring F. These rollers contact the projection I and the bore of the ring F but have slight clearance with the projection J. Under normal conditions a reversible drive through the rollers K<1>, K<2>, takes place between the members B, C. If, however, abnormal shocks occur on the steerable wheels these are not communicated to the stem B as the rollers K<1>, K<2> tend to bind and lock against the bore of the fixed ring F.

Abstract: 778,080. Two-part couplings. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. July 13, 1955 [July 14, 1954], No. 20527/54. Class 38 (1). [Also in Group XL (c)] In electronic equipment mounted on a frame 10, 11 slidable in channel members 21, 22 so as to be withdrawable from an operative position to an inspection position, the inner end of the frame terminates in a plug member comprising an insulating sheet 30 on each side of which contact strips 24 are held by a designation plate 17 and a strip 33 having lateral lugs 34, 34<SP>1</SP>. The plug co-operates with a socket mounted on a panel 32 carrying the members 21, 22, the socket consisting of a pair of gate members pivoted in a frame 36, 37, 38 and each comprising an insulating block 40 carrying strip contacts 41. In their inoperative positions the gates are swung outwardly against stops 48 by springs 43, 43<SP>1</SP> but on insertion of the plug, lugs 34, 341 engage abutments 44 on the gates and swing them inwardly so that the contacts 41 engage plug contacts 24. A catch 34 in the channel member 22 retains the frame in its operative position. Fig. 3 shows a modification wherein the gates are not actuated by the plug. In this case one of the gates carries a cam 67 integral with a lever 65 and co-operating with a cam block 68 on the other gate. Thus after insertion of the plug actuation of lever 65 closes the gates on to the plug contacts against springs 72, 72<SP>1</SP>. A peg 62 carried by the plug enters holes in the gates so that removal of the plug is prevented until both the gates are opened and the catch 31 is released. The plug contacts 61 in this construction are moulded in a plastic block 60. Specification 737,160, [Group XXXIX], is referred to.

Abstract: 1381683 Making helical seam tubes HOESCH WERKE AG 2 May 1973 [4 May 1972] 20923/73 Headings B3A and B3E  In making welded helical seam tube from metal strip, the resistance to bending of the strip is measured prior to the strip entering the tube forming device, and the instantaneous value so measured is used to control the tube forming device so that the strip curvature and residual stresses in the tube are maintained within predetermined limits. In Fig. 1, the strip 1 passes through a straightener 2, edge trimmer 3, feed unit 4, roll unit 51, 52 which bends up the edges of the strip, and into a roll curving unit of which roll 8 is adjustable normal to the plane of the strip. The edge bending unit is intended to compensate for the tendency of the tube to arch outwardly in the region of the helical seam weld, and the force necessary to bend the edges is measured in a transducer 12 and taken as a measure of the resistance of the strip to bending. This measure is compared with a norm, and any deviation is passed through a delay device 16 so that roll 18 is adjusted by servo motor 18 to apply curving forces to each part of the strip in accordance with the resistance to bending of that part of the strip as measured when it passed rolls 51, 52.
