Title: Improved Multirank Multistage Shift Register
IPC: G11C19/00
Filed: 1966-10-19
Abstract: 1,158,134. Shift registers. HUGHES AIRCRAFT CO. 19 Oct., 1966 [22 Oct., 1965], No. 46681/66. Heading G4C. [Also in Division H3] The stages of at least one rank of a multirank multistage shift register may be simultaneously set to states preselected by the couplings between the respective stages and a segmented clock pulse line. As shown (Fig. 3), a dual-rank shift register 40 comprises an upper rank formed of stages 11U-14U and a lower rank formed of stages 11L-14L, each stage comprising a NAND-gate and a flip-flop. The upper rank is provided with an upper clock pulse line 17 and the lower rank with lower segmented clock pulse lines 45, 55 which during normal operation carry identical signals. Data from a source 23 is fed to the first upper stage 11U and during successive clock pulse periods (alternately appeating on the said upper and lower clock pulse lines) is passed in sequence through stages 11L, 12U, 12L, 13U, 13L, 14U and 14L to output terminal 26. To set the stages of the lower rank to said preselected states, a command signal is issued to control circuit 25 (Fig. 4a, not shown) whereby coincident clock pulses are generated on lines 17, 45 and 55 and a zero data signal is fed to input stage 11U. As a result, all the upper stages are set to binary 1 states and all the lower stages are set to binary 0 states. After a short delay, the command signal further causes a binary one signal to be generated on line 45 and a binary 0 signal on line 55. Depending on whether switches 51-54 are connected to line 45 or 55, the respective lower stages are then set to their binary 0 or 1 states. This presetting operation is performed within a single clock pulse period. The upper clock pulse line 17 may also be segmented and switches corresponding to 51-54 provided (Fig. 5, not shown) if it is required to preset the upper rank also. The register may be fabricated using integrated circuit techniques (Fig. 8, not shown), each stage comprising three field effect transistors (Figs. 6 and 7, not shown). The switches may be preset by selectively etching away portions of conducting strips overlying the integrated circuit chip, a mask for this purpose being illustrated in Fig. 9 (not shown). Alternatively, connections may be provided to a control panel for selective operation of the switches.

Title: Production of propylene polymers by polymerization of propylene using ziegler catalysts
Inventor: WEBER HEINZ
IPC: C08F10/06
Filed: 1964-11-26
Abstract: Propylene polymers are produced by homopolymerization or copolymerization of propylene using a catalyst composed of an organometallic compound or metal hydride and a compound of a transition metal of Groups IV to VI of the Mendeleef Periodic System at a temperature of from - 20 DEG  to + 160 DEG  C. and a pressure of from atmospheric pressure to 25 atmospheres wherein the polymerization is carried out in the presence of an ethylenically unsaturated halogen compound which is a substituted alkene containing three or four carbon atoms and at least two chlorine and/or bromine atoms and having a terminal double bond, one of the halogen atoms being bound in the 1- or 2-position and another halogen atom being bound in the 3 position of the substituted alkene.  Polymers produced are polypropylene, copolymers of ethylene/propylene, propylene/butene-1, and a terpolymer of ethylene / propylene / dicyclopentadiene.  Unsaturated halogen compounds exemplified are 2,3 - dichloropropene - 1, 1,2 - dibromo - 3 - chlorobutene - 1 and 1,2,3 - trichloropropene-1. Also specified are 2-chloro-3,4-dibromobutene-1 and 1,2,3 - trichlorobutene - 1.  Catalysts exemplified are 3TiCl3.AlCl3 with diethyl aluminium chloride, triisobutyl aluminium, butyl lithium or lithium aluminium hydride, and VOCl3 with diethyl aluminium chloride or methyl aluminium sesquichloride. Polymerization is effected in organic solvents such as petroleum ether alone or mixed with trichloroethylene, and cyclohexane.  In one example, propylene is polymerized first with lithium aluminium hydride and then 3TiCl3.AlCl3 is added and the polymerization is completed. The unsaturated halogen compound acts as a molecular weight regulator.  Conventional co-catalysts for increasing the stereospecificity of the catalyst may be co-employed.  In a comparative example, 2-methyl-4-chlorobutene-2 is used as a regulator.

Abstract: 1366387 Coin-freed apparatus NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP and ANRITSU ELECTRIC CO Ltd 20 Oct 1971 [26 Oct 1970] 48763/71 Heading G4V [Also in Divisions H3-H5] A prepayment telephone apparatus has shoots A, B for two different value coins, e.g. 10 yen and 100 yen, and the control circuitry is such that the low value coins are collected in preference to the high value coins, all uncollected coins being refunded at the end of a call. Each shoot has a closure flap (not shown) which opens and an electromagnet 10M, 100M which energizes when the calling subscriber goes offhook, and each has a coin dimension and weight tester which rejects unsuitable coins. Selected coins pass into a storage shoot where they are arrested by stops 15, 15<SP>1</SP> associated with electromagnets 10M, 100M respectively. A low value coin (shoot A) operates a lever 21 thereby energizing relays in the control circuit. High value coins (shoot B) are held between the coils 23 (LPA, LPB) of a bridge circuit (Figs. 3A and 3B, not shown) for scanning the coin material. This bridge performs two balancing operations. If it does not balance with a first set of component values in the bridge circuit, a relay operates after a certain time interval connecting in a second set of components, the two operations being necessary because the high value coins may be of nickel or silver. If the bridge balances in either condition a relay is energized in the control circuit. If not the coin is refunded by first energizing electromagnet 100S placing a stop 18<SP>1</SP> in the shoot and then resetting electromagnet 100M to remove stop 15<SP>1</SP> thereby returning the coin via 25<SP>1</SP>. The electromagnets then return to their initial state allowing the next coin to reach stop 15<SP>1</SP>. Coins are collected when a metering pulse is received from an exchange. In such cases electromagnet 10T or 100T, is operated to place a stop 16 in the coin refund passage and to remove a stop 17 across the coin collect passage. The other electromagnets then operate as before, and finally electromagnet 10T resets. At the end of a call all electromagnets are reset and any remaining coins refunded. Gaps 14 in the respective shoots refund coins if more than a certain number are inserted into the store. When a high value coin is collected i.e., no low value coins are present when the metering pulse arrives ten pulses are counted before the next coin collecting operation is performed.

Abstract: 1,003,367. Pressure testing using sound waves. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 10, 1964 [Dec. 28, 1962], No. 48918/62. Heading H4D. Apparatus for testing evacuated containers for their degree of vacuum comprises means for causing a wall of a container to vibrate, means for detecting the vibrations produced thereby and means for indicating the magnitude of the detected vibrations. The invention is applied to automatic apparatus for rejecting containers having less than a predetermined degree of vacuum. In the embodiment of Fig. 1, containers 2, supposedly evacuated, travel along a conveyer belt 1 to be brought, one at a time, into a test position. At the test position is sited a magnetizing coil 3, forming, with capacitor 4 a tuned circuit resonant at the frequency of the energizing oscillator 5. The thus produced alternating magnetic field, together with a steady field caused by a D.C. bias current through the coil, causes the lid of a positioned container 2 to vibrate with an amplitude dependent on the degree of vacuum within the container. The sound caused by the lid vibrations is detected by a microphone which sends a signal via an amplifier 8, a filter 9 having a pass band excluding noise and centred on the frequency of oscillator 5 and a detecting diode 10 to the grid of a valve 11. The valve is non-conducting until the output of the microphone reaches a level indicating that an unsatisfactory vacuum is present in the tested container when it conducts and energizes a relay 12 to cause a rejection mechanism 13 to reject the faulty container. The filter 9 may comprise a Wien-bridge oscillation type circuit with just insufficient feedback to cause oscillations. In a second embodiment, Fig. 2 (not shown), designed so that the rejection mechanism will not be actuated by extraneous noise at the frequency of oscillator 5, the output of amplifier 8 is fed to one input of a phase-sensitive rectifier, the other input of which is fed with the output of oscillator 5. The output of the phase-sensitive rectifier is integrated and used to actuate a relay at the predetermined level of microphone output. The output of oscillator 5 is fed to the coil 3 via a phase shift network which is adjusted to give an output from the integrating means just below the critical level when a satisfactory container is tested.
