Title: Improvements in and relating to rotary drills
IPC: B23Q5/32
Filed: 1948-04-12
Abstract: 649,453. Drilling-machines. WERF C. EN STORK HIJSCH N.V. April 12, 1948, No. 10147. Convention date, April 30, 1947. [Class 83 (iii)] A drilling - machine for working in strata of varying hardness hav. ing means for controlling the pressure exerted on the drill bit and wherein the feed movement is effected by the differential rotation between a nut and a feedscrew, is characterised in that a coupling member transmitting the drive from the feed screw to the nut comprises a change-speed gear, the operating member for which is connected with the nut so that downward motion of the nut in a forward feed direction causes the circumferential velocity of the nut to be increased and vice versa. The drill rod 1 which carries a bit at its lower end is secured to a feed-screw 2 by a holder 3. A sleeve 5, slidably keyed to the feed-screw 2, is driven by gearing 6 to rotate the drill and at its upper end carries a bevel gear 19 engaging a bevel pinion 18 on the end of an adjustable friction drive gear 14, 16. The friction. wheel 16 is adjustable across the face of the disc 14 to vary the speed at which the latter drives, through gears 11, 12, the feed nut 8. Adjustment of the friction wheel 16 is effected by a yoke 21 secured to a link 22 connected to an arm 24 of a bell-crank lever, the other arm of which carries a yoke 26 engaging the feed nut. A spring 9, the compression of which is controlled by a hand wheel 10 screwed to the casing 7, bears on the nut and as the nut is moved downwardly in the feed direction the speed of rotation of the nut is automatically increased to give a faster feed rate. On encountering excessive drilling resistance, the nut is forced upwardly and the speed of rotation and hence the feed rate is automatically de. creased. When the nut rotates more slowly than the feed screw, the drill is withdrawn. The bell-crank lever may be moved by hand, utilizing the extension 27, if required.

Title: Improvements relating to time delay circuits
IPC: H03K7/08
Filed: 1947-04-17
Abstract: 639,722. Pulse gating circuits. HIGHAM, E. H., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. April 17, 1947, No. 10244. [Class 40 (vi)] In a gating circuit for passing an input signal only if it occurs a predetermined time interval after a reference signal, the reference signal trips a time base circuit which after a predetermined delay reduces the cathode bias fed from a control valve to a cathode-coupled gating valve so that the gating valve becomes conductive to pass signals applied to its input circuit. In Fig. 1 a sawtooth waveform initiated by the reference signal is generated by the Miller valve VTB and is applied as a negative going voltage to the normally conducting valve V1, valve V2 being cut-off. At some point along the sloping edge of the sawtooth wave the cathode potential of V2 falls sufficiently to render valve V2 conducting when the next positive going pulse appears at capacitor C1. The delay may be adjusted by potentiometer R5, the circuit may act as a frequency divider by using the same signals to trigger the time base and as a gating signal, the delay being adjusted so that the output pulses occur at a frequency which is a sub-multiple of that of the input pulse train. Capacitor C2 and diode D1 comprise a D.C. restorer circuit. In a modification, Fig. 3 (not shown), the signals to be passed by the gate are first applied to a phase-inverting valve which is directly coupled to the grid of the gating valve. In a further modification, Fig. 4 (not shown), both the positive going gating signals and the input signals are applied to the grid of the gating valve, the signals being ineffective to render the gating valve conducting until a gating pulse is present simultaneously. Specification 639,719 is referred to.

Abstract: 1,187,513. Transistor switching and gating circuits; magnetic storage arrangements. SPERRY RAND CORP. 4 March, 1968 [6 March, 1967], No. 10378/68. Addition to 1,079,877. Headings H3B and H3T. In electrical apparatus as set forth in Claim 1 of Specification 1,079,877, the electronic switching circuit, which has a bi-stable memory element 18 connected to one terminal B and a driver 12 and sense amplifier 10 connected to the other terminal A, enables bi-directional current flow through the memory element 18 and comprises two like conductivity transistors Q1, Q2 connected in series and respective diodes D1 and D2 connected across each transistor so as to conduct current in the first and second directions. The circuit is used to read out information from a plated wire memory 18 by applying pulses 46, 42 to the base of each transistor. The transistors Q1, Q2 then operate in the inverted mode to conduct and connect the " 0 " or " 1 " bit stored in the memory 18 to the sense amplifier 10. Information may be read into the memory from the bit driver 12. A positive bit pulse from 12 supplied together with the pulses 46, 42 causes diode D1 and transistor Q2 to conduct so as to cause current to pass in one direction (from A to B) through the plated wire memory, which stores this bit " 1 " or " 0 ". Transistor Q1 and diode D2 are biased off during these conditions. By applying a negative bit from 12 together with pulses 46, 42 transistor Q1 and diode D2 conduct and Q2 and D1 turn off so that current passes the other direction (from B to A) through the wire memory which stores another state " 0 " or " 1." Further circuits 21 similar to 41 may be connected to the same sense amplifier 10 and bit driver 12. The transistors Q1, Q2 may be replaced by a single double emitter transistor (Q3, Fig. 5, not shown), having a common collector (59) and base (57). The Specification discusses the possibilities of integrated circuits for a circuit using the same conductivity-type transistors.
