Title: Mobile agricultural machines
IPC: G06M3/00
Filed: 1971-09-06
Abstract: 1358178 Harvesters; distributors R HESSEL 6 Sept 1971 [8 Sept 1970] 41465/71 Headings AID and A1F [Also in Division G4] Apparatus for determining for example the acreage sprayed by an agricultural vehicle includes a magnetically operated switch 10 controlled by a magnet 9 attached to a wheel of the vehicle to supply pulses representing the displacement of the vehicle via a switch 14, closed when the vehicle is spraying, to a counter 12 so that the count represents the acreage sprayed. As described switch 14 is hydraulically controlled such that whenever liquid is flowing through a valve 5 to a pipe 6 and spray tube 7 the liquid pressure in the pipe 6 closes the switch.  The apparatus may also be used in harvesters or sowing machines in which the switch 14 is operated by the movement of a machine part. The magnetic switch 10 may be replaced by a mechanical switch.

Title: Heat sensitive copying
IPC: B41M7/00

Abstract: 972,695. Thermographic copying methods and apparatus. MINNESOTA MINING & MANUFACTURING CO. Dec. 2,1960 [Dec. 3, 1959], No. 41546/60. Headings G2A and G2C. A copy is made thermographically by irradiating a graphic original having differentially absorptive areas to form a heat pattern corresponding to the graphic pattern and then bringing the heat pattern into heat-conductive pressure contact with a heat-sensitive copy paper. As shown an original 15 is moved past a lamp in an elliptical cross-section reflective housing 17 and between the nip of a pressure roller 13 and a driven roller 12 around which is led a strip 10 of heat-sensitive copy paper. One of the rollers bears a resilient covering, preferably roller 13. When the roller 13 is raised by operation of arms 24, switch 25 is opened so that the lamp is extinguished and feed of the sheet 10 stops since it slips on the driven roller which preferably is of polished metal. A switch 26 operated by the original may effect the control of the pressure roller and lamp automatically. The lamp 17 may be enclosed in a transparent evaculated housing having an outer reflective coating (Fig. 3 not shown).

Abstract: 1,002,679. Electric resistance furnaces. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Jan. 9, 1963 [Nov. 21, 1961], No. 41590/61. Heading H5H. A furnace unit includes a tungsten filament/quartz tube radiant heating element disposed adjacent a reflector, a duct being formed in, or partially by, the reflector for the passage of coolant and/or the protection of the reflecting surface from dust or scale. A cylindrical furnace (Fig. 1, not shown)- e.g. for heating steel billets-may be composed of a pair of semi-cylindrical units, or a furnace of arbitrary cross section may be formed by a plurality of smaller interlocking units. Each individual unit 22 includes an aluminium reflector of parabolic section (Fig. 3(b), not shown), with its ends classed by plates which support the ends of the heater in split ceramic collets, and which are themselves bolted as at 33 to a pair of common annular furnace end plates. Each reflector has a backing plate shaped to form cooling ducts with the reflector's rear surface, and the longitudinal edges of the reflector/backing plate structure are shaped to permit pivotal interlocking with adjacent units (Fig. 4, not shown). Water is supplied to the cooling ducts of each unit by common manifold 35 and pipes 34, and the reflectors 24 are protected from dust and scale either by individual quartz windows closing the opening of each unit (Fig. 3(b), not shown), or by a common tube mounted about the furnace axis; gaseous coolant may be passed down the ducts, or down the annulus formed by the windows or tube with the reflectors. Units may be connected end-to-end to vary the furnace length, and a desired temperature gradient at the ends of the furnace may be obtained by appropriate outward curvature of the furnace end-plates. A part-parabolic, part-cylindrical reflector is described (Fig. 7, not shown).

Title: Process for dyeing or printing polyester or polyamide fibres
IPC: D06P3/54
Filed: 1977-10-10
Abstract: Textile material consisting wholly or partially of polyester or polyamide fibres or filaments is padded or printed with aqueous padding liquors or printing pastes which contain at least one dispersion dye. After padding or printing the textile material is brought into contact, directly or after intermediate drying, with methylene chloride vapour. The dye is fixed by causing the methylene chloride vapour to condense on the padded or printed textile material and leaving the thus treated textile material to dwell. The cold fixing process requires a small amount of methylene chloride. Deep, level dyeings are obtained.

Title: Improvements in or relating to control apparatus using magnetically recorded programmes
Inventor: JACKSON JOHN ALFRED
IPC: G05B19/16
Filed: 1962-11-15
Abstract: 991,038. Cutting-machines. E. K. COLE Ltd. Nov. 14, 1963 [Nov. 15, 1962], No. 43160/62. Heading B4B. [Also in Divisions B6, G3 and G5] In a Control apparatus for a machine of the type wherein a body in the machine and a magnetic track are advanced forwards step by step and in synchronism to a position where an operation is to be performed on the body, a pick-up head is adapted to be moved backwards over a predetermined length of the track during each stopping period, the backward movement of the head increasing the relative speed between the track and the head so that any signal received by the head during its backwards movement is of sufficient amplitude to be subsequently used to control the operation of the machine. The machine may be a paper-cutting guillotine wherein marks such as 4-6, Fig. 1, are recorded on a magnetic tape or wire 1. When the mark 4 passes a pick-up head 2 a pulse induced in the head causes slowing down of the back fence and the tape. When the mark 4 passes head 3, the back fence is stopped so that a cutting operation may be carried out. Whilst the tape 1 is stopped or moving slowly a pulse 5 may be missed by the head 2, and this is avoided by moving the head 2 backwards during the stopping period; means are provided to prevent a second pulse, which may be produced by a mark when the tape is re-started, from passing to the utilization circuits. Control circuit.-A pulse from the " stop " head 3, Fig. 2, passes through processing circuits 13-15 to operate the motor switch 16 and the knife control 17, and also triggers a multivibrator 18. The latter operates a solenoid 20 which moves the head 2 backwards by a predetermined distance. If a pulse is detected by head 2 during this movement, it passes through processing circuits 7-9 and a gate 10 to a store 11 so that when the back fence moves again it will do so at the slow speed. The gate 10 is opened via unit 22 when multivibrator 18 is triggered and is closed again when multivibrator 18 returns to its initial state and head 2 returns to its initial position. When a cut has been made and the back fence commences to move at its slow speed, a signal is fed from a knife-operated switch to remove the pulse from store 11 and to close the gate 10 for a short time so that a pulse produced by a second passage of mark 5 past head 2 does not pass to the store 11. Two tapes with the same information may be used and the outputs of two stop heads fed to a coincidence gate at the input of unit 17 so that a spurious pulse on one of the tapes will not cause the knife to be operated.
