IPC: A01B3/72
Filed: 1918-10-30
Abstract: 134,314. Sannazzaro, G. B. Oct. 30, 1918. Anchoring and securing apparatus.-In order to prevent overturning and slipping of capstan or anchor carriages when in use in rope-traction ploughing or cultivating, the wheels on the side nearest the cultivated land are replaced by a sled rigidly connected to the carriage by a projecting frame or the like and adapted to bear horizontally and vertically against the ground and to travel in a prepared furrow, or to cut its own way through the ground. Fig. 1 shows the sled E connected to the carriage A by a frame D and travelling in a prepared furrow. It consists of a long piece of angle-iron arranged as shown. When it is arranged to cut its own path, the vertical part projects downwards into the ground and the horizontal part rests on the surface. The length is such that steering-mechanism may be dispensed with, and stability is ensured in carriages having, normally, two wheels only.

Title: Electronic Invoicing or Billing Machines
IPC: B41J21/14
Filed: 1968-04-18
Abstract: 1,176,441. Electrical control of printers. KIENZLE APPARATE G.m.b.H. 18 April, 1968 [25 April, 1967], No. 18397/68. Heading G4H. In a typing machine there is a programme mechanism and an associated tabulation control store containing a number of store positions in each of which there is a number to be used for selecting the typing position across the paper, and a number giving instruction as to what is to be typed in that position. The typing position is determined by displacement of the carriage 4 or, in other forms of typewriter, by the displacement of the print head. In either case sliding contacts 6 move over a coding bar 5 to give a group of coded signals 8 representing the typing (or tabulating) position. These signals are compared at 7 with desired position signals 9 coming either directly from the programme mechanism 1 or from the tabulation control store 2. The comparator gives high, equal or low signals on leads 11a, 12 and 11. The signals on leads 11 and 11a move the carriage 4 in the appropriate directions until the actual position agrees with the desired position. The equal signal on lead 12 may then cause the programme mechanism to imitate the printing of the appropriate data in the position set. If the store 2 is being used, the programme mechanism 1 merely selects one of the store positions by a signal 15. The tabulation position is then read out and the carriage moves accordingly. When equality is reached the signal on line 13 allows the corresponding command number to pass to the programme mechanism 1 so that the desired information shall be printed in this position. The next operation may be given by a further command from the programme mechanism to select the next store position. This may be achieved by a repeated instruction to step a given number of positions to find the next position to be read out. The store 2 may be a plug-in unit designed for a particular operation, e.g. book-keeping. It is replaced with another for different operation. It may be a permanent store.

Abstract: 1494390 Continuous graphitization VEREINIGTE ALUMINIUM-WERKE AG 2 May 1975 [24 May 1974] 18518/75 Heading C1A [Also in Division H5] In a continuous process for the graphitization of baked preformed carbon bodies, the bodies that are to be graphitized are embedded in a granular, heat insulating bed of carbonaceous packing material which is contained in close-coupled continuously moving furnace cars, and in which the ends of stationary current supplying graphite electrodes projecting downwards from above are immersed for resistance heating the bodies that are to be graphitized, the electrodes being spaced apart in the direction of travel of the cars. The passage of the graphite electrodes through the packed bed is facilitated by vibrating them horizontally. The electrodes may be protected against atmospheric oxidation above the bed and up to electrode holders by high-temperature-resistant steel jackets. The carbonaceous packing material in the furnace cars may become partially graphitized and may later be used for forming the baked carbon bodies. The packing material may be a coke material (calcined anthracite, petroleum coke, pitch coke and metallurgical coke specified) or mixtures of sand and coke. Alternatively silicon carbide may be used.
