Title: Improvements relating to Rotary Switches
Inventor: COLLINGS REGINALD JEFFREY
IPC: H01H27/06
Filed: 1966-12-14
Abstract: 1,160,140. Rotary switches. D. H. BONNELLA & SON. Ltd. 12 Dec., 1967 [14 Dec., 1966], No. 56027/66. Heading H1N. An automobile ignition switch has a rotary selector drum 4 having a plunger 5 co-operable with notches in a housing 1 to define accessory (Fig. 1), off (Fig. 2) ignition (Fig. 3) and start (Fig. 4) positions. Drum 4 has an integral pawl 6 and is made of resilient plastics so that the pawl is resiliently biased against a slider 3 received in a housing recess 2. The pawl may alternatively be a separate arm linked to the drum and biased by a spring (Fig. 7). During rotation from the accessory to off position (Figs. 1-2), pawl 6 pushes slider 3 to a first end of recess 2 and then moves along the inner face of the slider. During movement to the ignition position (Figs. 2-3) the pawl moves to the end of the slider, and during movement to the start position (Fig. 3-4) the pawl leaves the slider and rides along the housing. During reverse movement back to the ignition position (Figs. 4-5), the pawl rides along the housing till it engages the slider and pushes it away from the first end of recess 2. The end of the pawl now springs down into a gap between the recess and slider, Fig. 5, thus preventing return to the start position (Fig. 4) without first reaching the " off " position (Fig. 6), during which movement (Figs. 5-6) the pawl pushes the slider to the second end of the recess and then rides back on to the slider inner face.

Filed: 1970-11-27
Abstract: 1333418 Axial-flow fans SIEMENS A G 27 Nov 1970 [ 28 Nov 1969] 56585/70 Heading F1C A supporting structure 2, Fig.1, for a motordriven fan unit 1,9, comprises arms 5 radiating from a central ring. Each arm has a substantially axial portion 11, adjacent its end remote from the central ring. The portion 11 has a substantially semicircular cross-section as shown in Fig. 3, with its convex surface directed inwardly so as to avoid sharp edges in the region of the fan blade tips 12 and thereby reduce noise. Bent reinforcing portions 14 additionally act as guides for air travelling past the arm. The part of each arm between region 11 and the central ring is substantially U-shaped in cross-section with its opening directed towards the fan. There may be three arms angularly spaced by 70, 145 and 145 degrees around the central ring, and seven fan blades so that only one blade edge at a time passes an arm. The structure may be stamped from sheet material.

Title: Electronic clock
IPC: G04R40/04
Filed: 1967-12-13
Abstract: 1,214,488. Electric clocks. CENTRE ELECTRONIQUE HORLOGER S.A. Dec. 13, 1967 [Dec.13, 1966], No.56604/67. Heading G3T. An electronic clock is controllable by a radio time signal constituted by a carrier wave modulated once every second to indicate the seconds and in the first second of every minute, a second time to  indicate the minutes, and comprises an HF, receiver 1, a detector 2, a monostable multivibrator 3, a logic control circuit 4, and a driving motor M for a time indicating means, and its control circuit 5. The control circuit 4 comprises transistors T 6 , T 7 , with emitters and collectors connected together. The base of the transistor T, receives the output of the detector 2 consisting of positive pulses spaced by a tenth of a second at the beginning of each second and during the third tenth of a second if each minute, whilst the base of the transistor T 6  receives the output at a point S, of the multi-vibrator 3 consisting of positive pulses of 0À3 secs. duration, terminating at the end of the first tenth of a second of each second and spaced by 0À7 secs. The bases of the transistors T 6 , T 7  are thus at zero potential simultaneously only during the third tenth of a second of each minute, to cause transistors T 8 , T 9  to conduct to provide minute signals by illuminating a lamp L. These may be discontinued if desired by opening a switch I. A further ouput point S 2  of the multi-vibrator 3 provides seconds pulses which render transistor T 10 , T 11  conducting to energize the stepping motor M driving the time indicating means. The alternative embodiment illustrated in Fig.3 includes means for correcting the time indicating means should this be slow or fast, and comprises an HF. receiver (not shown), a detector including diodes D 4  , D 5 , and a monostable multi-vibrator 6 associated with transistors T 12  to T 15  to provide minute signals by energizing a lamp L 2  as in the first embodiment. Seconds pulses at the output point S 4  of the multi-vibrator 6 render transistors T 18 , T 19  conducting to energize the time indicator driving motor M 2  via a transistor T 20 . When the time indicator is correct a rotary brush B driven thereby passes between and out of contact with two stationary contacts R, A at the instant of generation of the minute signals by the lamp L 2 . When the time indicator is fast the contacts B, A engage when the minute signal is generated and a transistor T 17  is rendered conducting to pass a signal to a multi-vibrator 7 to prevent conduction of the transistor T 20  for one second, thus causing the motor M 2  to miss one step. When the time indicator is slow the contacts B, R engage when the minute signal is generated and a pulse passes via a transistor T 16  to the transistor T 19  to cause the motor M 2  to perform an additional step. In a further embodiment the time indicator motor is controlled by a multi-vibrator the frequency of which is controlled by a circuit responsive to the difference in frequencies of the seconds pulses and the output signals of the multi-vibrator.

Abstract: 1285600 Subaqueous drilling CHEVRON RESEARCH CO 19 Nov 1969 [19 Nov 1968] 56692/69 Heading E1F A marine conductor extends from a submerged wellhead assembly 40 to a floating platform and includes at its lower end portion a telescopic section 72. Cables 86 connected to the platform and extending around pulleys 90 on the wellhead assembly exert a downwardly directed force on the conduit at a location above the telescopic section to prevent buckling in the conduit. One end of each cable may be connected to the conduit as shown, or one or two cables may be looped over pulleys secured to the conduit with the ends of the or each cable being secured to the platform. The cables, which may be of nylon, rubber, steel, or steel and nylon, are tensioned, and are able to stretch as the platform and thus the conduit above the telescoping section 72 rises with respect to the sea floor and to exert a substantially constant force on the conduit. If necessary the length of the cables may be increased by running the cables over pulleys on the platform. The cables together with guide posts 48 act as guides for the blowout preventor stack 60 during lowering thereof while suspended from the conductor.

Filed: 1972-12-19
Abstract: 1410629 Digital transmission: bandwidth compression; facsimile system XEROX CORP 19 Dec 1972 [29 Dec 1971] 59573/72 Headings H4P and H4F The facsimile signal whose peaks represent black and white (A, Fig. 2, not shown) and whose intermediate portions carry grey information, has its peaks boosted (B) and clipped (F), and alternate ones inverted to give a narrower bandwidth three-level signal (H) while retaining the intermediate amplitude (grey) information in the sloped portions. An amplifier 11, Fig. 1, peaks the original facsimile signal A and an amplitude detector 14 senses the low level peaks (w), to earth at 15 the input of an inverter 16 giving a signal D in which the black peaks (b) are now at the low level. These peaks are now in turn cut off by a circuit 19 controlled by a circuit 17 which senses the zero cross overs of signal D and which produces a square wave E corresponding to the signal D. This square wave is halved in frequency by a bi-stable 25 which controls an inverter 21 so as to invert alternate pulses of signal D, giving the three level output signal H. Decoding at the receiver (Fig. 4, not shown) involves sensing zero cross overs of the three level signal (at 32), filtering (at 33) to give a signal M, Fig. 5 (not shown), which then has alternate peaks inverted (at 37) by a full wave rectifier after inversion (at 35). An amplifier (39) produces a replica (P) of the initial facsimile signal (A).

Title: Electrical discharge machining
IPC: B23H1/02
Filed: 1973-12-21
Abstract: 1442150 Electro-erosion INOUE-JAPAX RESEARCH Inc 21 Dec 1973 [23 Dec 1972 28 May 1973 8 June 1973 8 Aug 1973 5 Sept 1973 19 Sept 1973] 59469/73 Heading B3V [Also in Division H3] In an electrical discharge machining method, the shape of the site of the tool electrode 1 at which an electrical discharge initiates is ascertained and an electrical parameter of the discharge is established at a particular level preset to correspond to the particular shape detected. The particular shape of the electrode 1 at the point at which the discharge initiates may be ascertained by detecting at a certain time the gap resistance, gap impedance, discharge current, discharge voltage or the amplitude of the discharge current or voltage. In one embodiment, a voltage is applied across a liquid dielectric filled machining gap G from a power source 3 when a switch 4 is made conductive by a trigger 5. The subsequent initiation of the discharge across the gap G is sensed by a resistor 6 which triggers a circuit 81 comprising a Schmitt trigger and a monostable multivibrator. After a predetermined time interval, signals are applied to AND gates 84a-84c for a certain period by a timer 82 comprising a monostable multivibrator. If the discharge created is on a planar electrode area B, the current signal through the resistor 6 actuates one only 83a of three discriminators 83a-83c each of which is triggered at a different current level. An output is produced from the AND gate 84a which resets a flip-flop 80a to turn off a transistor 7a. As a result, a resistor R 1  is brought into circuit with the machining gap G causing the discharge current to be reduced. If the discharge is created on a contoured electrode area C, a higher current signal is produced to cause two discriminators 83a, 83b to be triggered, whereupon, via gates 84a, 84b, flip-flops 80a, 80b and transistors 7a, 7b, two resistors R 1 , R 2  are brought into circuit so reducing the gap current further. Three resistors R 1 , R 2 , R 3  are brought into circuit if the discharge is created on a tip portion A of the electrode 1 resulting in a minimum gap current whilst none of the resistors are brought into the circuit if the discharge is created on a cavity area D resulting in a maximum gap current. If an abnormal discharge is produced, it is detected by a circuit 85a-85d. Instead of controlling the gap current, the duration of the discharge may be adjusted (Figs. 3 and 6, not shown). In the latter embodiment, the pulse intervals are extended if an abnormal discharge is detected. Alternatively, both the current magnitude and the duration of the discharges may be adjusted (Figs. 4 and 5, not shown). During the approach of the electrode 1 towards the workpiece 2 after having been retracted therefor, the current magnitude to discharge duration ratio may be modified continuously or stepwise (Fig. 7, not shown).
