IPC: B21C27/04
Filed: 1962-08-03
Abstract: 1,015,185. Extruding. HYDRAULICK G.m.b.H. Aug. 3, 1962 [Aug. 5, 1961], No. 30049/62. Heading B3P. An extrusion press has at least one air vent 8 for evacuating air from the container bore 5, the inner end of the vent being closed before and after the evacuation by a power-operated valve 11. After insertion of a billet 2, the bore is closed by the press ram 7 and vave 11 is then opened automatically by a double-acting fluidpressure piston 15 supplied through a valve 19 controlled by limit switch 22 actuated by the ram. When the valve 11 is fully open a switch 27 operated by the piston 15 starts an electric motor 26 driving suction pump 14 which evacuates the bore 5. At a predetermined degree of vacuum, a switch 25 is opened whereby valve 19 is reversed to move the piston 15 inwardly and close valve 11. A switch 31 then emits a signal to start the extrusion.

Title: Improvements relating to spindle mountings for spools or other carriers of ribbon orthread-like material
IPC: G03B21/32
Filed: 1937-11-03
Abstract: 505,034. Winding thread. SMITH, R. A. (Community Cinema Corporation) Nov. 3, 1937, No. 30135. [Class 120 (ii)] [Also in Group XX] A spindle mounting for spools or other carriers of ribbon or threadlike material, has a radially compensating member to enable the spindle to engage a plurality of spools having bores of different sizes or other characteristics, and means are 'provided for controlling the position axially along the spindle of each of such plurality of spools. An application to kinematograph apparatus is shown in Figs. 4 and 8. The spindle 70 has a groove for a "latch" 73 pushed outwards by springs 75 but retained by headed studs 80. The lug 82 projects through the spindle when the latch is depressed. The disc 85 carries' a cup 88 containing a spring 87 acting on a pin 86 the movement of which is limited by projections 90 engaging grooves 91. A flat pin 95 is similarly urged outwards by a spring 97. Figs. 5-7 show the types of bore fitted to different sizes of spoof. An 8 mm. spool, Fig. 7, is pushed on the spindle until the sides engage notches 78. The location is assisted by the spring 93 which engages the notch 94 and prevents depression of the pin 86 without considerable force. The spool is so placed on the spool that the pin 95 engages one of the openings 100 to give a driving connection. When a 9'5 mm. spool, Fig. 6, is pushed on to the spindle the latch 73 is depressed and the projection 82 serves as a stop for the central tubular member 43. The pin 86 enters one of the holes, 41 for a driving connection. A 16 mm. spool, Fig. 5, is located by notches 77, the pins 86 and 95 being depressed. The latch 73 engages one of the corners of the aperture in the side of the spool and thus provides the driving connection.

Title: Improvements relating to the control of electrically effected adjustments of horizontal boring machines
IPC: B23Q5/54
Filed: 1949-11-24
Abstract: 658,492. Control of A.C. motors. KEARNS & CO., Ltd., H. W., and KEARNS, Sir H. W. L. Nov. 24, 1949. No. 30137. [Class 38(iii)] [Also in Group XXII] Adjustment of the spindle head or worktable of a horizontal boring machine is made by a three-phase motor j (not shown) to which A.C. current is supplied for coarse adjustments or which, to effect slow and then fine adjustments, is supplied with D:C. current under control of a slowly rotatable switch l, with which the motor runs in phase, the switch being rotatable continuously or step-by-step. The forward and reverse coils o<SP>1</SP>, o<SP>2</SP> of the motor .are connected to one of the A.C. lines through interlock contacts o<SP>3</SP>, o<SP>4</SP> and a reversing switch o<SP>5</SP> and the forward and reverse connectors n<SP>1</SP>, n<SP>2</SP> in the A.C. lines are operated by relays (not shown) when a control lever h is moved into either one of notches i<SP>2</SP>, i<SP>3</SP> in a slotted gate i. When the lever is moved into either of the notches i<SP>5</SP>, i<SP>6</SP>, switches p<SP>3</SP>, p<SP>4</SP> are closed by a relay s and D.C. current is supplied by a transformer p<SP>1</SP> and rectifier p<SP>2</SP> through the rotatable switch l to the motor (not shown). A reversible motor m (not shown) driving the switch l receives current through a switch t<SP>1</SP> and a switch u which is held closed by a delayed action relay v energized by D.C. current from a tansformer y and a rectifier x through a switch w. The motor m then runs continuously to rotate the switch L and supply intermittent D.C. current to motor j so that both motors rotate in phase and slow adjustments are made to the machine. When, however, the lever h is opposite the notches i<SP>7</SP>, i<SP>8</SP>, the switches t' and w are open but, when the lever is moved into either notch, t<SP>1</SP> is closed again and a switch t<SP>2</SP> opened to break the circuit through relay v. The delay action of the relay v will, however, hold the switch u closed sufficiently long to cause a partial rotation of the switch l and of the motor j so as to give a fine adjustment to the machine. Fine step-by-step adjustment is obtained by repeated movement of the lever h into the notch i<SP>7</SP> or i<SP>8</SP>. A lamp m<SP>3</SP> indicates when D.C. current is being supplied. to the motor j. The gate slot may be of U-shape with notches on opposite sides of one limb of the U.

Abstract: Siloxanes of the formula <FORM:1060057/C3/1> wherein R and R1 are each a monovalent hydro-carbon (h.c.) radical, OR11 is a radical of the formula -O-(-CxH2xO-)y-R111 in which R111 is a monovalent h.c. radical, x is 2, 3 or 4, y is at least 1 and has an average value for the 4 OR11 radicals greater than 1, and n is an integer from 2 to 700, can be made by reacting a siloxane of the formula R-SiH2O-(-SiR12O-)n-SiH2-R with a glycol ether of the formula HO-(-CxH2xO-)y-R111 in the presence of a catalyst, e.g. a dialkylhydroxylamine, stannous octoate or dibutyl-tin dilaurate.  The reaction is usually effected in an inert diluent at 0 DEG  to 50 DEG C.  Examples of the above method of making the polyoxyalkylene-siloxanes are given.  The tetrahydrogeno-siloxanes used as the starting materials can be made by reacting a linear a , o -dihydroxy diorganopolysiloxane with RSiH2X, in which X is a hydrolysable atom or group, preferably Cl, in which case the reaction is effected in the presence of a neutralizing agent, such as a tertiary amine.  Uses: as surface-active agents, particularly in the manufacture of polyurethane foams.  In Example 1, tolylene diisocyanate was incorporated with stirring into a mixture of a condensation product of glycerol and propylene oxide (M.W. of 3500), triethylenediamine, stannous octoate, water and the polyoxyalkylene-siloxane, and when the mixture begins to foam, it is poured into a mould.

Title: Improvements relating to automatic and semi-automatic telephone systems
IPC: H04Q3/00
Filed: 1923-12-05
Abstract: 225,068. Coventry Automatic Telephones, Ltd., and Collyer, J. E. Dec. 5,1923. Automatic exchange systems; metering. - Metering is effected over a fourth wiper of the line switch by a relay at the first selector which has already been employed in the setting up of the connection, and which is energized again by booster battery applied to the test wire at the connector. The invention is described with reference to a selector of the Strowger type in which metering is effected (1) by the change-over relay and (2) by the rotary stepping relay. The line switch may be of the type shown in Specification 208,075. Metering by the change-over relay, Fig. 2. Line relay 101 and release relay 102 energize in the usual manner, and change-over relay 103 operates over its lower winding and connects up relay 104. Relay 101 repeats the dialled impulses to vertical magnet 106 at back contact 118, and holds relay 103 when off-normal contacts 113 are operated at back contact 124. Relay 103 relapses when the impulses cease and connects up rotary magnet 107, while stepping relay 104 remains held over off normal contacts 113 and interrupter contacts 126. Rotary magnet 107 and stepping relay 104 interact as long as the test wiper engages earthed terminals to energize the latter. When an idle line is found, switching relay 105 which was previously short-circuited over the test wiper energizes and extends the talking and test wires. Relays 101, 102 release, and the upper winding of change-over relay 103 is connected to the test wire, to which booster battery is momentarily applied at the connector when the called subscriber replies. Relay 103 then operates and closes the metering circuit 117. When earth is removed from the test wire at release, relay 115 falls back and connects up release magnet 108. Metering by the rotary stepping relay, Fig. 3. Rotary stepping relay 204 operates over its upper winding in the setting up of the connection, and when switching relay 205 energizes, its lower winding is connected to the test wire, so that it responds to booster battery to close the metering circuit. Alternatively, the lower winding may be dispensed with, since switching relay 205 locks to the test wire at contact 228 in series with the upper winding of relay 204, which does not operate until booster battery is applied on account of the high resistance of the former.

Title: Improvements in or relating to process for treating a secondary alkyltoluene
IPC: C07C6/12
Filed: 1954-10-25
Abstract: A process for treating a secondary alkyltoluene comprises contacting, under substantially anhydrous conditions and in the substantial absence of hydrocarbons which are not inert to the action of the HF-BF3 agent and do react with the secondary alkyltoluene charged, isopropyltoluene and/or secondary butyltoluene, with at least 0.5 mols. of BF3 per mol. of secondary alkyltoluene in the feed, and an amount of liquid HF at least sufficient to form a distinct acid phase, at a temperature between -20 DEG  and +80 DEG  C. for a time at least sufficient to permit an appreciable amount of rearrangement reaction, and recovering poly-secondary alkyl toluene from the acid phase.  Preferred products are meta cymene and 3,5-di-isopropyltoluene.  Reactive hydrocarbons are olefines, xylene, di-ethylbenzene, ethyl toluene and ethylbenzene.  Non-reactive hydrocarbons are isopentane, butane hexane and benzene.  In a preferred embodiment a feed consisting of a mixture of all the isomers of isopropyltoluene which have been obtained by the alkylation of toluene with propylene in the presence of aluminium chloride catalyst is mixed with liquid HF and the mixture cooled to 10 DEG  C.  Subsequently BF3 is rapidly intermingled to produce a HF-BF3-isopropyltoluene complex, the temperature being kept below 15 DEG  C. and the pressure being maintained at about 100 pounds per square inch.  The mixture then passes into a reactor where the temperature is maintained at 15 DEG  C. and then into a decomposing zone where the HF and BF3 are distilled off.  A product fraction of essentially pure 3,5-di-isopropyltoluene is obtained.

Title: Improvements relating to electronic counters
Inventor: IRVINE JOHN ANDERSON
IPC: H03K29/00
Filed: 1957-10-01
Abstract: 877,761. Electronic counting-apparatus. FERRANTI Ltd. Sept. 24, 1958 [Oct. 1, 1957], No. 30671/57. Class 106 (1). In a multi-denominational counter with a number of multi-cathode glow-discharge counter tubes each with a pair of transfer electrodes between each pair of digit-representing cathodes, the pairs of overlapping voltage pulses which effect count-up or count-down according to their relative timing are applied to the transfer electrodes of each tube via means operative whenever the discharge in one tube represents a digit other than zero to inhibit counting action in the tube of next higher order. As shown, a and b pulses (ab representing a count-up and ba a count-down) are applied to transfer electrode connections G a  and G b  of decimal counting tubes 12, 32, 52 ... through amplifiers 15, 34, 53 ... and 20, the amplifiers 34, 53 ... having inputs also from the 1-9 cathode circuits of the previous denominations and acting in effect as " and " gates. Assuming the counter to be set at zero (as by pressing button 26 which brings all " 0 " cathodes down to - 150 v.) then an a pulse transfers the discharge in each tube to the a electrode " above " 0, and the associated b pulse to the b electrode. At the end of the b pulse the discharge commences to move to the "1" cathodes, the rise in potential at 24 acting through 34, 53 ... to lower the potential of the a electrodes of tubes 32, 52 ... sufficiently to attract the discharge of those tubes back to "a above 0" rather than to "1," and these tubes are read as recording "0." Similar action takes place until tube 12 has been counted up to cathode 9, when the next pair will transfer the discharge in 12 to " 0 " and 34 will receive no input from 24 after the b pulse so that 32 moves to " 1 "; tubes of higher denomination being inhibited by the positive signal from 41. Considering a count-down, tube 12 will always be counted down 1 digit by a ba pair of pulses, but any other stage will only be counted down if its discharge is at a cathode, i.e. if all the lower stages register "0." The counter may include tubes with other than ten cathodes for counting in a radix other than 10, or for counting in degrees and minutes of arc (by use of a sixcathode tube in the second denomination).

Abstract: 446,514. Valve circuits for wireless reception. RANDALL, C. E., 10, Douglas Road, Luton, Bedfordshire. Oct. 26, 1934, No. 30790. [Class 40 (v)] A highly damped resonant circuit has its response discriminatively augmented by the introduction of an unmodulated frequency produced separately from the circuit, so that the impedance of the circuit is reduced at that frequency. A received signal is amplified at V1 and fed to a damped circuit L2, rl, C2. An oscillator V2 feeds carrier frequency energy over coupling Z1, Z to the clamped circuit so as to reduce its resistance at the carrier frequency only. A detector V3 rectifies the resulting signal. The oscillator V2 may produce oscillations of any frequency that it is desired to augment in the received signal. The invention may be applied to a multi-channel transmission system in which a single carrier wave is modulated by three telegraphically controlled frequencies. At the receiver, the carrier is applied to three circuits of the type shown in the Figure, each oscillator being tuned to one of the modulating frequencies.

Abstract: 290,118. Herborn, L., Horn, W., and Horn, A., (trading as Horn S÷hne, H.). Nov. 17, 1927. Regulating and control-transmitting apparatus for winding and paying-out apparatus ; driving- gear; brakes; self-sustaining gear.-In braking- mechanism for hoists in which the brake is interconnected with a, coupling between the driving and driven shaft, lost motion between the two shafts is provided, in order to release the brake before commencing to drive and to re-apply it before releasing the driven shaft. The first movement of the driving-shaft a rotates the disc e thereby tensioning the springs h until projections on the disc abut against and drive other projections on the brake disc d secured to the driven shaft. In the spring-tensioning interval, wedgeshaped projections k on the inner face of the disc e engage projecting pegs r on a loose sleeve p and move the latter axially to operate the bellcrank lever t and thus transmit a brake-releasing movement to the toggle W, Fig. 2, against the action of the spring X. When the hoisting- effort ceases, the spring h restores the disc e and allows the spring X to re-apply the brake. In a modified construction the member d and the loose sleeve p are formed with conical co-operating brake surfaces, the lever t and associated brake straps being omitted. In another modification pivotal brake shoes acting on the interior of the drum d are used. In this case, during the spring-tensioning movement, a cam on the member e forces a member to move radially outwards towards the periphery of the drum d and in so doing pulls the ends of the brake shoes towards one another and takes off the brake.
