Title: A universal plant cutter
IPC: A01D45/00
Filed: 1946-11-05
Abstract: 617,757. Tree cutters. BOUDIKINE, N. Nov. 5, 1946, Nos. 32768/46, 34377/46 and 6283/47. [Class 145 (ii)] [Also in Group I] A wheeled machine for cutting on a large scale hard or semi-hard stemmed plants comprises a transverse solid cutter shaft (or shafts) in front of and/or laterally of the machine, the cutting edges being in one piece with the body of the shaft, the said edges extending from one to the other end thereof and the diameter of said shaft, including the cutting edges, being less than one inch. In the construction shown, a motor 10, drives through gearing and a clutch element 22, one of the land wheels 14. The clutch is controlled by a spring 24 and arms 23 from a cable 9 operatively connected to the cutter shaft 56 which is mounted in tension bearings 53. On meeting any undue resistance these bearings are moved rearwardly, thereby pushing a rod 55 against one end of a rocker 32 which moves the other end of said rocker forwardly and so pulls on the cable 9 which is attached thereto, thereby disengaging the clutch 22; the machine remaining stationary until the obstruction has been cut throughthis accomplished, re-clutching occurs. The cutter shaft is rotated through gearing 38, 39, 40, 42, 43, chain 46 and sprocket 48 from the shaft 33 of the motor. A reverse gear (position 43a, and gears 44, 45) is provided and is actuated by a lever 51 and cable 50. In a modification, the cutter is arranged at an angle to the longitudinal axis of the machine, and here the sprocket 48 driven a shaft which is geared to the cutter shaft. In a further modification, a plurality of cutters are arranged in alignment.

Title: A typewriting machine associated with data processing devices
Inventor: MUCKE HEINZ
IPC: G06F3/09
Filed: 1964-08-12
Abstract: 1,070,853. Typewriters &c. BœROMASCHINENWERK SÍMMERDA VEB. Aug. 12, 1964, No. 32832/64. Heading B6F. [Also in Division G4] The position of the carriage of a typewriter - calculating machine closes one or more electric circuits which may be used to control various operations. A contact bar 1 is rigidly connected to the frame of the machine and carries a continuous contact rail 3 and contacts 2 corresponding to the typing positions. Contact rollers 4 secured to the carriage and insulated from it, establish an electrical connection between the rail 3 and the appropriate contact 2 at any typing position of the carriage. A contact 5 is opened when the carriage moves and closes only when it is stationary. Thus the circuit is only completed if the carriage is stationary. Each contact 2 is connected to a programme panel in the form of a plug-board or a switch-board, and can be connected to any desired number of control lines 7 through diodes 6. By this means the usual form bar can be dispensed with.

Abstract: A sheet of polythene supported on a backing is printed while molten with a mixture comprising one or more dyes and/or pigments and a material capable of forming a solid solution with polythene, the mixture having a softening temperature lower than that of the molten sheet.  Suitable materials are polystyrene, hydrogenated polystyrene, polythene, pyrolysis products of polythene, chlorinated polythene, polyisobutylene, rubber, cyclised rubber, Neoprene, butyl rubber, guttapercha, gum elemi, ester gum, hydrogenated ester gum, hydrogenated castor oil, paraffin, micro-crystalline wax, ozokerite, carnauba, ceresin, montan and bees wax, chlorinated naphthalene and diphenyl, asphalt, polypropylene, polypropylene sebacate, polyvinyl isobutyl ether. Suitable dyes are the wax-soluble "Waxoline" (Registered Trade Mark) dyes.  The printing mixture may be applied cold, hot or dissolved in hydrocarbon, e.g. xylene, or chlorinated hydrocarbon solvents.  The backing may be a polished metal roller or band and may be coated with separating aids such as a high melting-point grease, aluminium or zinc stearate, sodium silicate or a detergent, or paper or fabric.  Preferably the sheet is solidified immediately after printing by chilling with the printing plate or roller.  The polythene sheet may be heated to the molten state by hot rollers or infra-red heaters.  Polythene coatings on fibrous materials made as described in Specification 600,687, [Group VIII], may be printed before the coating has cooled from the molten state. Sheets formed by the process of Specification 567,358 may be printed during their formation.  In the example the inking roller is made of "Welvic" (Registered Trade Mark) and the transfer roller is of steel.

Stud-and-eye fastenings.-A fastener specially applicable for vehicle curtains comprises a relatively fixed base part and a rotary head, resilient friction means being provided between the base and head to retain the head in position. Fig. 3 shows a fastener for connecting adjacent edges of curtains, and comprising a circular base 2 fixed to the curtain 4 by prongs 3 and a stiffening-plate 5 and having an oval boss 1 drilled and grooved in its face to receive springs 6 adapted to bear frictionally against the base of an oval head or button 7. This button is fixed on a stem 8 extending through the base and curtain and also through another head 9, by which the stem and head 7 may be turned from the other side of the curtain. In Fig. 5, the boss 1<a> on the base is reduced and the stem 8<a> carries spring arms 6a in the form of a cross bearing on the bottom of the base. In the form shown in Fig. 4, the fastener is arranged for fixing to the framework by a screw 10 and nut, or a wood-screw, fixed in the base 1<a>, and the oval head 7 turns on a stem 8<1> integral with the base, between which and the head springs are arranged as before. In all cases, the base of the head may be grooved for retention by the springs in certain positions.

Addition to 227,072 and 314,359, [both in Class 98 (i), Photographic cameras &c.]. [Classes 97 (i), 98 (i), and 98 (ii).] The method of producing coloured designs for textile fabrics described in Specification 227,072 as modified by Specification 314,359 is further modified in that the diapositive of at least one colour element is produced by photographing on the projection plate a negative image of the element, while the diapositive of at least one other colour element is produced, as in the prior Specifications, directly as a negative of all the colour elements other than the one considered, so that no relative correction for glass thickness is required as between the diapositives of the separate colour elements. The negative image may be the projection on a plain, for example white, screen of a negative obtained by photographing the woven sample through appropriate filters. The woven sample used for direct photographic production of the diapositives of one or more colour elements may be left in place for the registration of the negative image of another colour element, and may be then replaced by the plain screen. All the diapositives may be made on one plate, which may be left in place after the direct production of the diapositives and used after registration has been effected for the production of a diapositive of the negative image on the plain screen. In a further modification each diapositive is produced by photographing an enlarged negative photograph of a woven sample, the enlarged negative having been spotted by hand in accordance with the desired distribution in the fabric of the colour in question.
