A skive cutting machine comprises a rotatable knife 10 and a mounting 14 movable to perform a cutting cycle and wherein the knife is rotated throughout a cutting stroke by means of a driven belt 20 which operatively engages a driving wheel 22 for the knife. The mounting 14 is slidable via bearings 18 on guide bars 16 secured to the frame plates 36 which are provided with sleeves 39 movable on vertical posts 40. The belt 20 is driven, via a pulley 26, by an electric motor 24 stationarily fixed to the machine frame, the other end of the belt being guided by a fixed pulley 28. The mounting 14 is traversed along the bars 16 by means of a number of V-belts 50 passing round pulleys 59, 48, the pulley 48 being rotated by means of an electric motor 44. The drive from the belts is transmitted to the mounting 14 by means of cams 70, 72 pivoted on the mounting. The cam 70 is urged into contact with the belts 50 by means of an abutment 98 slidably mounted on bars 96 and urged into contact with a pin 86 on the cam 70 by means of a rack-and-pinion drive 52, 92 actuated when a clutch 47 is energized; the energization is effected in response to a signal from a microswitch or photo-cell associated with the feed for the material to be cut. After the cut has been made, the cam 70 is disengaged from the V- belts by means of a cam (104, Fig. 7), and at the same time a cam (110) abuts a pin 88 on a second pivoted cam 72 on the mounting causing the latter to be returned to its starting position. The mounting 14 and guide bar assembly is raised on the post 40 at the end of the cut prior to the return stroke by means of a rack-and-pinion and crank device actuated via a pneumatic or hydraulic ram.

Abstract: 1,193,776. Compression moulding pulverulent materials. SCHLOEMANN A.G. 14 May, 1968 [26 May, 1967], No. 22801/68. Heading B5A. In the compression moulding of pulverulent materials either wetted or not wetted with a liquid, e.g. to form anode material for the production of aluminium, air is extracted from the material within the mould cavity immediately prior to the moulding operation, by the application of vacuum to a sealed enclosure defined between the upper surface of the moulding die and an advancing press ram by a sealing ring arrangement which is slidably mounted on the press ram. In a vertical press, wherein the material is compressed in a die 1 between advancing upper and lower plungers 2, 3, the upper plunger 2 is removable from the die 1 and displaceable transversely with respect thereto to permit charging of the cavity from a horizontally reciprocable hopper (C), Fig. 1, not shown, whereafter the upper surface of the die is cleaned by a stripper (D). The moulded article is ejected by the lower plunger 3 and displaced from the upper surface of the die 1 on to a roller table (F) by a pusher (E), the necessary clearance being obtained by sufficiently raising the upper ram 2 or by lowering of the die 1. Sealing between the upper plunger 2 and the upper die face is effected by a sealing ring 4 comprising an inner part 4a which is sealingly and slidably engageable with the ram 2, and is supported thereon by a collar 2a against which it may be spring urged, and an outer part 46 sealingly engageable with the die; the inner and outer parts 4a, 4b being engaged at a universal joint permitting axial misalignment of the ram 2 and die 1. Sealing between the lower ram 3 and the lower face of the die 1 is effected by a seal 5, comprising outer part 5b which is secured to the die 1, and inner part 5a with respect to which the ram 3 is slidable, the inner and outer parts 5a, 5b being separable by power cylinders 5c. After sealing the mould enclosure and applying vacuum thereto from a source connected to the lower outer ring 5b and via orifices 4c in upper inner ring 4a, the material is compressed by the advancing rams 2 and 3 whilst maintaining the vacuum, and material drawn between the lower inner and outer seals 5a, 5b subsequently falls therefrom upon their separation by the cylinders 5c. In a horizontal press, both rams are sealed by seals similar to the seal 5. A filtering ring may be provided which is of slightly larger inner bore than the diameter of the ram and connected to the inner sealing ring whereby blocking of suction apertures provided in the outer seal is avoided; material on the ring being displaced therefrom into the die 1 by the advancing ram.

Title: Improvements in or relating to lifting mechanisms for tractor-propelled implements
IPC: A01B63/112
Filed: 1962-06-14
Abstract: 1,011,017. Tractor power lift mechanisms. C. VAN DER LELY N.V. June 14, 1962 [June 7, 1961], No. 23003/62. Heading A1P. A tractor power lift mechanism providing automatic draft control is capable of use in drawing or pushing an implement, the draft responsive mechanism being capable of operating both under tension and compression The embodiment shown in Fig. 1 comprises a three-point linkage in which the upper link 10 is pivotally connected to a member 18 pivoted on the frame of the tractor at 17 and operating at its lower end a rod 40 which controls a hydraulic circuit for operating the linkage. For drawing an implement the link 10 is connected as shown in full lines to transmit compressive forces whereas when the tractor is pushing an implement the link 10 is disposed in the position 10<1> to transmit tensile forces. The rod 40 is biased by spring 49 into contact with the member 18 and is connected by a linkage 38, 37 with a control valve 36 which in its neutral position shown allows fluid to pass from pump 30 through passage 36A to the sump 32. When the valve 36 is moved to the right by the rod 40 the operating cylinder 24 is connected to the sump to allow the linkage to drop and when the valve 36 is moved to the left by rod 40 the operating cylinder 24 is connected to the pump output in order to raise the linkage. The valve 36 is also controlled manually by lever 44 through a linkage 43, 41, 38, 37. In an embodiment two links are provided in the positions 10, 10<1>, the one in position 10 only working under compression and the one in position 10<1> only working under tension. In a further embodiment (Fig. 3) the upper link 10 is pivoted to a member 78 which is pivoted to the tractor at 77. Two struts which only operate under compression are pivoted to the member 78 as shown and are also pivoted to a spring biased rod 68 which operates a valve controlling the hydraulic circuit as described above. In the embodiment of Fig. 5, the upper link 10 is connected to the rod 40 by a pair of pivoted members 96, 100. When the link 10 is put in tension, the members 96, 100 pivot at 101 so that the member 100 contacts a fulcrum member 105 and so operates the rod 40. When the link 10 is put under compression the pivoting of the members 96, 100 is restricted by a part 104 fixed to member 100 so that when part 104 comes into contact with member 96 further movement of this member operates rod 40.
