Filed: 1973-04-04
Abstract: 1432581 Selective printing CENTRONICS DATA COMPUTER CORP 4 April 1973 [28 April 1972] 16047/73 Heading B6F [Also in Division G4] A dot-matrix impact printer comprises a plurality of print wires with drivers, and a deflection assembly movable transversely to the direction of movement of the document, openings arranged at spaced intervals in the deflection assembly receiving a free end of each wire, the drivers not moving with the deflection assembly, and the deflection assembly moving through 1/nth of the line in printing the line, where n is the number of print wires, the drivers being controlled from a store via a character generator. Each character is a 5 x 7 matrix of dot positions. The rows of dots in the line are printed in turn, the paper advancing between one row and the next, or the paper may advance continuously and the deflection assembly move at an angle to compensate. There is one wire per ten adjacent character positions, and a recirculating register holding the line of characters to be printed supplies its contents repetitively to a character generator which is controlled by a decoded column count to provide the appropriate column of the appropriate character, a multiplexer selecting the appropriate dot of this column under control of a row counter, to load a buffer at a bit position appropriate to the character position, the buffer contents being passed in parallel to wire driver solenoids under control of a strobe pulse from optical sensing of a marked scale moving with the deflection assembly. A shuttle cam flange or timing belt is used to reciprocate the deflection assembly along the print line. The arrangement may also be used for curve plotting, the recirculating register using only one bit position per character position, and the character generator and multiplexer not being used.

Title: Improvements in or relating to hoists
Inventor: WHYTE BRYCE ALEXANDER CAMPBELL
IPC: B66B17/36
Filed: 1960-05-06
Abstract: 905,771. Builders' hoists. WOODALLDUCKHAM CONSTRUCTION CO. Ltd. March 27, 1961 [May 6, 1960], No. 16161/60. Class 78 (3). Associated with the or each shaft gate of a builder's or like hoist having control means for the hoisting mechanism adapted to be operated by a pull cable there is provided a safety mechanism comprising a device which, when the gate is closed, maintains a bight of predetermined size in an interlock cable associated with the operator's pull cable but, when the gate is open, permits reduction of the bight to introduce slack in the interlock cable whereby operation of the hoisting mechanism in response to normal movement of the pull cable is prevented. As shown, Fig. 1, an interlock cable 3 passes from the control lever 2 of the hoist motor 1, through bight-forming devices 5 associated with each gate 6, to a drum 7a of a differential pulley 7. A stop 9 is provided so that the permitted movement of cable 3 is sufficient to move the lever 2 from the brake position to the hoist position but is less than the slack which is introduced into the cable by the device 5 when a gate 6 is opened. An operator's pull cable 10 is secured to the drum 7b of the pulley 7. Each device 5, Fig. 2, comprises a double sheave pulley 5c mounted on an axle 5e secured to side plates 5a and a double sheave pulley 5d mounted on a removable axle 5f which is secured to the gate 6 by a chain 5g that when the gate is opened, the axle 5d is withdrawn, thereby allowing the pulley 5d to move up the side-plates 5a to produce slack in the cable 3. The full permitted movement of the cable 3 resulting from rotation of the pulley 7 to draw the stop 9 into engagement with a fixed guide 8 is then insufficient to move the control lever 2 from its braking condition. In a modification, the differential pulley 7 may be replaced by a simple pulley and the cable 3 passed over it to constitute the pull cable. Other modifications of the arrangement of the interlock, control and pull cables are described, Figs. 4-6 (not shown). Specification 739,382 is referred to.

Title: Improvements in or relating to the Manufacture of Caps or Bases for Incandescent Electric Lamps and Apparatus therefor.
Inventor: SCOULAR JAMES ALEXANDER
IPC: H01J9/30
Filed: 1916-11-10
Abstract: 111,138. Scoular, J. A. Nov. 10, 1916. Forming electric-lamp caps; moulding under pressure ; delivering molten metal.-In filling caps for electric incandescent lamps, glass or the like is run from a melting-pot into a receiver, is raked into a cap, and is then moulded. It may flow continuously from the melting-pot, or may be run out, under control of a hand tool, in separate quantities as required for individual caps. The caps may be inserted in moulds D, Fig. 1, which are provided with notches to receive the pegs on the caps, and need not be specially cooled. The moulds are mounted on one or more rotary tables A<1>, A<2>, in the lower faces of which are holes co-operating with spring plungers C to arrest the tables in definite positions. Perforate contact-pieces are placed in the caps over pins which project from or through the mould; this operation may be carried out by hand or by the machine described in Specification 111,139, [Class 83 (iv.), Metals, Working]. As shown in Figs. 1 and 4, the glass-receivers are troughs F<1>, F<2>, lined with graphite, or having longitudinal grooves filled with graphite, in which case they may be water-cooled. Instead of graphite, any refractory substance which does not adhere to the molten material and is a bad conductor of heat may be used. Either end, or as shown both ends, of each trough may be open for delivery of glass to the caps. The troughs are carried by two parallel rods F<3> which slide through brackets on the framework of the apparatus, and one rod is recessed to receive a spring detent in three positions such that either trough is under the delivery nozzle of the melting-pot E, or both are clear thereof, the glass then passing to a collecting-box &c. Within the troughs are brass or graphite scrapers H attached to an arm sliding on a guide J parallel to the troughs. A weighted lever K, having a pin and slot connexion to the bracket, is pivoted to a bracket on the rods F<3> carrying the troughs. Thus molten glass can be delivered from the troughs to the caps alternately on two rotary tables A<1>, A<2>. During the ensuing moulding of the glass, each cap is held firmly by a ring M descending on to it. Each water-cooled moulding-plunger carries two pins in line with those of the mould, the pins nearly meeting during the moulding. Subsequently the thin webs of glass thus left are broken to provide passages for the leading-in wires.

Filed: 1956-05-25
Abstract: The zone-melting process claimed in the parent Specification, in which the liquefied zone is supported by means other than a supporting crucible or the like, is applied to a semiconductor crystal, e.g. of silicon, immediately after it has been drawn from a melt in a crucible and before the crystal has been removed from the drawing device.  In the Figure a rod 4 of material to be treated is drawn from the funnel 14 of a crucible containing the melt 21, a heater <PICT:0809163/III/1> 3 being provided to maintain the material in the neck 2 of the funnel molten during drawing.  The drawing device comprises wheels 15 and 16, lower wheel 16 being driven at a required speed by rack 17, pinion 19 and belt 20.  The drawing device is mounted to rotate about a vertical axis in support 7.  Using the apparatus shown the crystal is drawn to a required length, the drawing operation is interrupted and heater 3 is then switched off. Zone-melting is then performed on the drawn length one or more times from top to bottom, the sequence of operations being then repeated. In a modification an additional drawing device may be used at the lower end of the drawn crystal and the two operations of zone-melting and drawing may be performed simultaneously.

Abstract: 912,578. Electric selective-signalling systems. PYE Ltd. May 9, 1960 [May 14, 1959], No. 16603/59. Class 40 (1). [Also in Group XIX] A machine for sorting wafers of semiconductor material according to their thickness comprises means for advancing the wafers to a measuring position in which an electric signal in accordance with thickness is produced for controlling the subsequent routing of the wafer concerned. As shown, Fig. 1, a feed finger 1, under the control of cam 16a, pushes the wafer to measuring position P and then retracts while cam 16b lowers the differential inductance measuring device 4 into contact with the surface of the wafer. After the measurement, one of the plungers 7a to 7f of the sorting mechanism is operated, as described below, according to the measured wafer thickness, the cams 16a and 16b then operate to lift the measuring probe and then to move the feed finger across until the wafer falls into tube 6 of the sorting mechanism from which it is deflected by the operated plunger, e.g. 7b, into the appropriate container, e.g. 11b. Cam-operated switch S1 is provided to delay operation of the plungers until the wafer measurement is complete and so prevent the mechanical vibration consequent upon their operation from interfering with the measurement, while cam switch S2 resets the circuit ready for the next wafer after the sorting operation is complete. Switches are associated with the containers 11a-11f to prevent operation of the machine if any of the containers are removed, and counters may be associated with the plungers to count both the numbers of wafers within a given size range and the total number of wafers sorted. Measuring and sorting circuit, Fig. 5. The output of the measuring transducer after amplification and rectification is passed to a cathode follower 14, the cathode resistor of which has a number of tappings connected respectively to the bases of transistors T. For each measurement, the voltages appearing at the tappings will be such that all the transistors below a given tapping tend to conduct but the uppermost of the group energizes its relay R4 to disconnect the power supply from the remainder. RL1 also energizes RL2 which locks and operates the associated plunger when the camoperated switch S1 has closed. In due course, cam switch S2 shunts out RL2 to reset the equipment.
