Title: Flow and pressure regulating control valve for hydraulic motors
IPC: F15B13/042
Filed: 1973-02-01
Abstract: 1422431 Rock drill feed GARDNERDENVER CO 1 Feb 1973 [12 June 1972] 5035/73 Heading B3C [Also in Divisions F2 and G3] In a valve for controlling the feed of a rock drill, a spool 54 is shifted by applying fluid pressure to either of ports 50 or 52 in excess of that applied to the other, the spool normally being held central by springs 86, 88 when there is no pressure differential between ports 50 and 52. If excess pressure is applied to the port 50 to move the spool downwards to connect a supply port 36 to a motor port 34 in a groove 56 valve element 82 moves downwards to cut off port 52 from the recess 45. At the same time, pressure in the groove 56, i.e. at the motor port 34, is fed via a passage 72 in the spool to the chamber 64 in which a valve element 74 slides. If the pressure thus fed is sufficient to overcome the pressure in port 52 acting on the valve element 82 the valve 74 will open to admit this pressure to the recess 45 where it will act to oppose the opening effects of the pressure fed to the port 50. Pressure at the motor port 34 is thus regulated to be substantially equal to that fed to the port 50.  A manually operated pilot valve (Fig. 2, not shown) has two outlet connections (180), (178) connected to the ports 50, 52 and fed via restrictions from a common inlet (120) connected to the supply pump. A screwthread operated reciprocating closure member has a flat V- section groove at its centre and the axial position of this groove determines the amount of pressure fluid by-passed to an exhaust connection (188) from each of the outlets, thus determining the pressures fed to the ports 50, 52 of the main valve.

Abstract: 642,655. Automatic voltage control systems. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 22, 1947, No. 5231. [Class 38 (iv)] [Also in Group XL (c)] The amplitude of oscillations derived from a source feeding a variable load is maintained constant by varying the value of an impedance connected across the load in accordance with the amplified output of a peak rectifier connected across the source. The Figure shows a source of oscillations 1 feeding into a variable load 2 which may, for example, be a grid-modulated R.F. amplifier stage. When the voltage across load 2 increases, rectifier 3 conducts and applies an increased voltage to the control grid of valve 11, thus unbalancing the comparison circuit comprising valves 11 and 12. The voltage appearing at valve 12 causes the impedance of valve 15 to be reduced. In a modification; Fig. 2.(not shown) the source of oscillations is balanced with respect to ground and the impedance across the load. is constituted by two valves connected with their anodes in push-pull, control grids in parallel. The value of their impedances is controlled by two rectifiers connected in a fullwave rectifier circuit across the source. Specifications 563,659 and 556,757, [Group XL (c)] are referred to.

Title: Method of producing 3-chloro-2-methylpropene-1
Inventor: KIRYU TOMOO
IPC: C07C17/156
Filed: 1966-02-07
Abstract: 3 - Chloro - 2 - methylpropene - 1 (i.e. methallyl chloride) is obtained by reacting a mixture of gases containing iso-butene and one or more other C4 hydrocarbons with chlorine at a temperature in the range - 50 DEG  to 60 DEG  C. in a molar ratio of chlorine to total butenes of not more than unity to convert the iso-butene present to 3-chloro-2-methylpropene-1.  The reaction is optionally carried out in the presence of from 0 to 5 mole per cent of oxygen based on the total hydrocarbons using molecular oxygen, air or mixtures of molecular oxygen and nitrogen or carbon dioxide to inhibit substitution chlorination of any paraffinic hydrocarbons present. The mixture of gases may comprise iso-butene in association with various proportions of a mixture of n-butenes containing butene-1 together with cis- and trans-butene-2. In particular, the return B-B fraction from petroleum naphtha, which also contains other specified hydrocarbons, is preferred.  The process is carried out under a pressure in the range 0.5 to 20 atmospheres using an amount of chlorine which ensures that the addition chlorination of butene-1 is minimal.  The chlorination products are then separated from butene-1 and any saturated hydrocarbons prior to isolation of the desired 3-chloro-2-methylpropene by conventional means.  Meso -2,3 - dichlorobutane, dl-2,3-dichlorobutane and 1,2-dichlorobutane are obtained by chlorinating mixtures of isomeric n-butenes.  The aforementioned dichlorohydrocarbons are also obtained along with ter-butyl chloride and 1,2-dichloro-iso-butane by chlorinating n-butenes in the presence of iso-butene and hydrocarbons.

Title: Phase correcting system for synchronous telegraphy
IPC: H04L1/00
Filed: 1961-02-15
Abstract: 945,816. Telegraphy. KOKUSAI DENSHIN DENWA KABUSHIKA KAISHA. Feb. 15, 1961 [Feb. 22, 1960], No. 5667/61. Heading H4P. The invention provides a phase-correcting system for a synchronous multiplex telegraph ARQ system. The basic system for each channel is indicated in Fig. 3. Received signals feed an error detector I, which detects any error in the mark/space ratio of each character, and to a unit IV, which counts the number of mark elements in each cycle of r characters (or during an integral multiple thereof). If the correct number of marks is counted by IV a counter V is started: if the number is incorrect counter V is reset. Counter IV is reset at the end of each r character cycle by unit II, as is unit III which indicates whether or not there is an incorrect mark/space ratio during the cycle. Counter V is reset if no error is indicated by III. If, therefore, an error is detected by III but the number of marks in the cycle is correct, counter V is operated, and if it reaches a number i it actuates a dephase indicator VI which operates a phase-shifter VII to correct the phasing of the system. Referring now to Figs. 1 and 4, which show a timing diagram and a detailed embodiment, respectively, received signals, e.g. as Fig. la, and comprising signals alternately on channels CH.A and CH.B, are fed to a sampling unit 2. Timing pulses, Fig. 1b, pass via a phase shifter 3 to unit 2 and to unit 4, which generates channel pulses, Fig. 1c. Unit 5 detects the presence of error in the mark/space ratio of each character and unit 6, the presence of an RQ signal, indicating that the subsequent characters are repeated characters. If either unit 5 or 6 gives an output counter 7 or 8 is started, dependent upon which channel the error or RQ has been detected. Bi-stable units 12, 13 are set when 5 gives an output and are reset when 6 gives an output. Unit 15 counts the pulses, Fig. 1c, from 4 and pulses at each r characters, i.e. the pulses are spaced by a repetition period. Unit 14 counts the number of mark pulses in each r character cycle and advances counter 17 if the number of pulses is correct but resets counter 17 via OR gate 23 if the number is incorrect. A trigger 16 is actuated if an error is detected by 5 and is reset by 15. If there is an output from either 12, 13, or trigger 16, OR gate 19 inhibits the resetting of counter 17 by a pulse from 15. When counter 17 reaches full count it actuates indicator 10, which shows loss of phase between the pulses, Fig. 1c, and the received signals. The output of indicator 10 sets 7 and 8 counting and, at each repetition cycle of unit 7, shifts the pulses from generator 1, Fig. 1b by one cycle. Trigger 22 is set by pulses from counter 7 and then reset. If either 12, 13 or memory 22 is giving an output pulses from 7 can not reset the indicator 10.
