Title: Improved automatic control means for roller-mills
IPC: B02C4/32
Filed: 1950-04-12
Abstract: 698,084. Roller mills. BUHLER, GEB. April 12, 1950 [April 14, 1949], No. 9025/50. Class 59 [Also in Group XXIX] Control means for roller grinding mills comprises a detector 15, Fig. 1, in the feed hopper, actuating a valve 13a seating on a piston 13 which controls a feed gate 12 at the hopper outlet, a piston 8 controlling a clutch 5 for the drive of a feed roller 4, and pistons 3 controlling the spacing of the roller 1 from the roller 2. Compressed air is supplied through a pipe 20, past a cock 21 to a chamber 17a above a piston valve 17 and also a port 17b controlled by the valve 17. The chamber is connected by a pipe 16 to the space above the piston 13. Thus. when air is supplied and no material is in the hopper, the valve 17 is held up by a spring and the air is exhausted through passages in the piston 13. When material is fed into the hopper, valve 13a is lowered and pressure builds up in the space above piston 13 and in the chamber 17a causing the piston to move down to open the gate 12, and the valve 17 . to move down to connect part 17b with a pipe 19 communicating with the cylinders of pistons 3 and 8. Hence the roller 1 is moved closer to roller 2 and the clutch 5 is engaged. If it is desired to empty the hopper quickly, the cock 21 is rotated to the position shown in Fig. 2, whereby the air supply is connected to pipe 22 to actuate a piston 23 which fully opens the gate 12, and a piston 9 which moves the piston 8 to engage the clutch 5, the roller 1 having moved away from roller 2. Specification 698,085 is referred to.

Abstract: 869,170. Liquid-ring pumps. NASH ENGINEERING CO. March 17, 1959 [Nov. 7, 1968], No. 9227/59. Class 110 (1). The casing 10, Fig. 5, of a liquid-ring pump has two lobes 24, 26, and partitions 32, 34 on the rotor and casing divide the working space into left-hand and right-hand working chambers. The outer ends of the chambers are closed by heads 12, 14, each having two inlet conduits 48A, 50A, Figs. 3 and 5, leading to two separate inlet ports (one of which is shown at 40 in Fig. 5) contained in each of two cones 36, 38. Each of the two inlet ports of each cone are associated with one of the two lobes of the respective working chamber. Each cone has two discharge ports (one of which is shown at 46 in Fig. 5), one for each of the two associated lobes, both discharge ports being connected in parallel to two discharge conduits 58, 60. Thus, the pump comprises, in effect, four separate pumps with independent inlet conduits, each pair of pumps sharing two parallel-connected discharge conduits 58, 60. Alternatively, a separate discharge conduit may be provided for each of the four pumps. Sealing liquid, such as water, is supplied through an inlet 45, Fig. 7, to a chamber 47 in each head 12, 14, whence some of it passes through an end clearance 55 and orifices 51,53 in the respective cone 36 or 38 to provide sealing between the cone and the rotor. In addition, some of the sealing liquid seals a stuffing-box 69, and the remainder passes through an opening 59 to the space 57 between the rotor and the respective head 12 or 14 to provide a sealing flow through a peripheral clearance 61. Air leaking from the discharge region into the space 57 by way of the clearance between the rotor and the cone 36 or 38 is drawn off through a hole 67, Fig. 8, and removed by the pump through the inlet ports such as 40. Specification 700,832 is referred to.

Abstract: 756,152. Manure distributers. NODEN, R. April 6, 1954 [April 7, 1953], No. 9293/53. Class 6 (1). A manure distributer comprises a frame 10 detachably mountable on a tractor between the front and rear wheels and fitted with a hopper 33 which feeds manure into a trough 15 carried by the frame, the material being ejected from the trough through an outlet 25 by a rotary agitator 20, 24 driven from the rear wheel of the tractor. The frame 10 has hooks 11 and stays 13 which engage a frame member 12 of the tractor to support the device cantilever-fashion. The trough 15 is slidably withdrawable from the frame 10 but is normally secured by pegs 17. Springs 35 hook over studs 34 to hold the hopper on to the frame. The agitator comprises a blade 24 on the spindle 20 co-operating with fixed vanes 22. The drive to the spindle 20 includes a pulley 26 loose on the spindle and a clutch disc 28 keyed to it, the position of the disc being controlled by a pivoted pendulum 31 so that when the tractor tilts over in working a furrow the pendulum swings to engage the disc and pulley, thus completing the drive. Pairs of units may be mounted one on each side of a tractor, the drive being taken to each in turn as the tractor tilts; the tractor may be fitted with one-way ploughs operating at the same time. A worm-feed may replace the blade 24.

Abstract: 1,075,816. Stamping; jointing by tubeexpanding. GENERAL DYNAMICS CORPORATION. March 5, 1965 [March 11, 1964], No. 9438/65. Headings B3J and B3Q. A method of forming a workpiece comprises placing a deformable pressure-transmitting medium or a liquid between the workpiece and a conductive driver and establishing a varying magnetic field to intersect the driver so as to force the driver against the medium or the liquid and the medium or liquid against the workpiece. A pad of rubber 20 may be used between a workpiece 22 and the cylindrical copper or aluminium driver 19 disposed on the flat forming coil 10. A die 24 is disposed above the work. The forming pressure may be intensified by tapering the driver (35, Fig. 2), which has three parts connected together, and confining the transmission medium (40) in a ring (41). As applied to shaping tubular work (58, Figs. 3 and 4) within a rubber sleeve (54), this is surrounded by a corrugated, aluminium or beryllium-copper, flexible driving sleeve (52). A split field shaper (48), with or without a corrugated bore, is arranged between the driver (52) and the coil (46), and the sleeves (52, 54) are confined endwise between members (60). The coil may be cooled, and the driver (52) formed of several layers. An internal die or mandrel may be used in the tube (58). Tubular work (58a, Fig 8) may be expanded by an internal coil assembly (63), acting through a corrugated driving sleeve (52a) and a flexible ring (54a). As applied to expanding the end of a tube (78, Fig. 6) in a tube plate (80), a plug of rubber (86) is expanded by a driver (84) operated by an external coil (82). A similar coil-and-driver arrangement acting on oil or paraffin (96, Fig. 7) may be used to subject work (90) to radial compression.

A harrow comprises tines attached to a frame 50 wherein each tine is supported by a support formed or carried on the harrow frame, each tine including a resiliently deformable portion 77 extending between the location of its support and the location at which the tine is secured to the harrow frame, the arrangement being such that during working the ground working portion 71 of each tine is movable relative to its support due to the deformation of the portion 77. As shown the tine passes through a hole 72 the walls of which act as a support. The resiliently deformable portion is formed as a number of bends 76 and the tine is formed from a single length of resiliently deformable material. The shape of the bends may be altered and two tines may be formed from a single length of material, one clamp being used to secure both tines. Specification 977,464 is referred to.
