Title: Positioning controlling apparatus
IPC: G05B19/18
Filed: 1973-06-25
Abstract: 1403656 Automatic control of position FUJIKOSHI KK 25 June 1973 [3 July 1972] 30113/73 Heading G3N Data for the control of the positioning of a machine having a plurality of drive axes, is recorded in apparatus comprising a flip-flop circuit 1, Fig. 1 which, when set by a sampling signal, produces a recording signal causing a magnetic disc or drum memory device 2 to generate a timing signal, which together with said recording signal enables a gate circuit 3 stepping a timing counter 4. When the counter 4 reaches a predetermined count a data selector 5 selects a block commencement code and writes it into the magnetic memory. A plurality of data registers 6A 6F storing data of respective axes have their data successively stored in the magnetic memory 2 when the timing counter 4 actuates the data selector each time it increases its count by one. A second data selector 7 has a word selection signal of one word length applied to it from a selector switch 9 to designate the last data register e.g. 6C which has to be recorded to complete one block of information or 'information word' and a coincidence circuit 8 compares the selection signal with the count of the timing counter and when coincidence is detected a reset signal is applied to the flip-flop thus completing the recording of the word in the memory device. The program stored in the magnetic memory is available to control a machine, e.g. an industrial robot, and Fig. 2 (not shown) illustrates the path of signals during the reproduction of data the flip-flop 1 being set to cause the read-out of information stored.

Abstract: 337,171. British Cotton Industry Research Association, Nuttall, T., and Shorter, S. A. Oct. 10, 1929. Feeding openers, &c.-A hopper bale opener, hopper feeder, &c. having a vertical spiked lattice or a spiked wheel, dividing it into two compart.- ments is provided with a duct leading from the front to the rear compartment whereby dustladen air short circuits the lattice &c. and assists in providing an adequate air supply for a combined cage or fibre conveying means. A hopper feeder a comprises a spiked lifting lattice d, beater e for throwing off surplus fibre, and beater j for stripping the fibre from the lattice. Dustladen air in the hopper short circuits the lattice and beater e by a conduit h, and passes into the rear part b of the hopper on its way to a high speed dust cage g and air trunk g<3>, along which the liberated cotton is conveyed by clean air, as described in Specification 317,592, a fan i withdrawing dust-laden air along a conduit i<2> from the cage g. To increase the draught through the machine, the beaters may be formed as fans, the draught assisting also to strip the fibre from the lattice d. In a modification, the conduit h is disposed outside the side of the hopper and reenters at the axis of the beater f which is formed as a mixed flow fan to draw in air axially and eject it radially. The two arrangements of the conduit may be combined.

Abstract: 364,705. Parachute harness and pack combined with seats and upholstery. SWITLIK, S., Broad Street, Trenton, New Jersey, U.S.A. Oct. 16, 1930, No. 31030. [Class 141.] A parachute, pack, and harness are combined with upholstery for a chair in which the passenger in aircraft sits, the arrangement being such that " slip " devices may be operated from a remote point or otherwise to free the passenger with his accompanying parachute, pack, harness, and upupholstery. The seat of the chair may be pivoted to enable the passenger to drop downwardly through exit doors in the aircraft. The parachute harness with its accompanying upholstery is arranged to be fastened about the passenger when the device is detached from the chair, and flaps on the upholstery are subsequently attached to the chair. The parachute harness carries the pack, and means are provided detachably to connect the parachute pull cord with the chair and for releasing the harness and pull cord therefrom. The upholstery is released prior to the release of the harness. The pack is released automatically when the wearer of the upholstery has dropped a certain distance. As shown in Fig. 1, the pack 18 is attached at 19 to the harness. The top covering 24 constitutes a canvas parachute with its edges tucked under itself. A withdrawing pin 31, Fig. 6, is attached to a wire pull cord 32 and passes through a flexible conduit 33 and on being pulled, springs throw open reinforcing tapes 25 and allow freedom to the parachute. Two withdrawing pins may maintain the pack closed. The pull cord 32 is attached to a ring 34 engaging a pocket 35 on the side of the padded upholstery. The upholstery is preferably tufted, including folded back portions for the back of the chair and its arm rests. A waist strap 52a on the harness carries a loop 47, Fig. 4, at the back of the wearer. The loop 47 passes through the back of the chair and is engaged by a withdrawal pin 46, capable of being operated by a pull cord 44 forming one of two branches attached to a cable 41, which may be operated by the pilot or crew from a remote position. The other branch 40 of the cable is attached to a withdrawal pin, capable of engaging a snap hook 36 on the pull cord 32. The waist strap 52a extends around the body of ,he upholstery, and has its ends secured at 52b under straps 61, which are also secured to straps 67. The straps 67 cross at the back of the upholstery and at the front carry a snap hook 56 and metal loop 54, which can be slid to different positions for adjustment. The straps 61 pass through loops 19 on the pack. A snap hook 60 may be attached to any ore of several loops 57, 58, 59. The chair, shown in Figs. 4 and 5, is provided with a seat 70 hinged to drop downwardly by means of supports 69 having members 72 for engagement by a pin 74 having an eye for the engagement of a bell-crank lever 76. The trap door of the fuselage is operated after releasing the upholstery from the chair and fastening the harness about the passenger.

Title: Improvements in and relating to a method of coating an article and the coated article so obtained
IPC: C23C4/08
Filed: 1960-09-12
Abstract: A coating is formed on a workpiece by introducing a powdered composition composed of 1-5% by weight of chromium and the remainder tungsten into the arc flame of an arc torch wherein an arc is stabilized by confinement within the walls of a passage which constricts the arc to a smaller cross-section than the arc would normally occupy, said arc flame being directed against the workpiece. The coating may be formed on a workpiece of magnesia or graphite or on a layer of alumina or zirconia applied to a graphite base, and is stated to be useful in the protection of rocket nozzles. Alternatively, an entire article such as a rocket nozzle may be made from the tungsten alloy by applying a coating on a pattern which is subsequently removed.  The powder used for coating may be made by mixing tungsten and chromium powders, sintering at 1600 DEG C. in 60% argon -40% hydrogen to form an alloy, and then crushing. Alternatively, a powder made simply by mixing tungsten and chromium powders may be used for coating and the coated body then heat-treated to form an alloy coating.
