Title: Audio-visual display system
IPC: G09B5/06
Filed: 1964-01-31
Abstract: A slide projector is controlled by a magnetic tape playback apparatus which also plays a commentary, the arrangement being such that the tape apparatus is turned off in response to a gap in the commentary. When a switch 11, Fig. 2, is closed relay 12 is energized and holds itself on through its contact 12b and energizes the tape drive motor through contact 12a sound signals from one track on the tape are then supplied to terminal 20 and pass through amplifiers 21 and 22 to loud-speaker 24, whilst command signals from another track may be supplied to terminal 41 to energize a slide changer actuator 65 via amplifier 42 and relay 45. Signals from amplifier 21 pass through amplifier 26 to energize relay 27, which disconnects terminal 30, and relay 33 which energizes relay 35. Contact 35a of relay 35 maintains the energization of drive motor 17 and contact 35b de-energizes relay 12. When the sound signals at terminal 20 cease for a few seconds relays 27 and 33 are de-energized music signals from terminal 30 pass to the loud-speaker, contact 35a stops the tape drive and lights a pilot lamp 40, and contact 35b allows relay 12 to be energized when desired through switch 11 to re-start the apparatus. A switch 51 may be provided to allow manual energization of the slide changer actuator 65.

Title: High frequency transistor structures exhibiting low collector capacity and low base resistance
IPC: H01L29/00
Filed: 1964-02-11
Abstract: In a junction transistor in which the base zone occupies only a limited part of the body cross-section the emitter zone is in an elongated recess in a base contact layer which substantially surrounds it, the layer being widened at the point at which a supply conductor is secured to it. The recess and the widened part of the base contact layer are preferably the same shape and size and may be arranged with their longitudinal dimensions in line, as in Figs. 6, 7, 8 and 11 (not shown), mutually perpendicular as in Fig. 5 (not shown) or side by side as in Figs. 1, 3 and 4 (also not shown). The recess is typically oval, rectangular or semi-circular. Preferably the supply conductors are thermocompression bonded to the emitter zone and base contact layer by means of a pressure chisel. In this case although the bonded area extends mainly in the direction of elongation of the chisel i.e. at right angles to the axis of the wire the maximum spread of wire material over the contacted surface is along the axis of the wire. Therefore generally the wires are arranged with their axes along the longitudinal direction of the recess and widened part of the base contact layer. If, however, short-circuiting of the emitter-base junction as a result of this spread is prevented, as by an oxide film on the semi-conductor or base contact material the wires may have their axes perpendicular to this. In a typical NPN germanium transistor, Fig. 2, the base zone is formed by diffusion into an N-type wafer from an indium-germanium source. An evaporated base contact 6 of aluminium indium alloy is alloyed to it and the emitter zone 5 then formed by diffusion from arsenic vapour. The layers are finally reduced to mesa form by etching. In an alternative method the emitter diffusion precedes formation of the base contact.

Title: Method of manufacturing a heat exchanger
IPC: B21D53/08
Filed: 1964-05-21
Abstract: A method of making a heat exchanger element comprises corrugating two metallic strips 1, 1a and then superimposing them so that the corrugations of the strips bear on one another over substantially the whole surface thereof. The corrugated strips may have openings 5 and associated wedges 6 formed therein or alternatively openings with wedges 6 1 and the wedges of one corrugation fit into or are aligned with an opening in an adjacent corrugation. The heat-conducting properties of the strip may be varied by altering the pitch of the corrugations by compression thereof. The corrugated strip may be fixed to a transistor support (7) (Fig. 7, not shown) or it may be wrapped around a lamp (Fig. 10, not shown). In the latter case, the wedges 6 1 are preferably used to keep the heat exchanger element in resilient contact with the lamp. The corrugated strip may also be formed into a cylinder, which is flattened by opening out one end radially, and the annular disc so formed also serves as a transistor support (Fig. 11, not shown).

Patent ES-351509-A1 (ES)
Title: Condition sensing circuit for telephone subscribers{3 {0 lines
IPC: H04Q3/00
Filed: 1968-03-12
Abstract: In an exchange system in which subscribers lines are directly connected to inlets of a crossbar switch, at least two outlet levels of the latter are reserved for making loop tests which can differentiate between " calling loop " and " permanent loop " conditions. As shown, the lines lg1-lg16 are connected to respective inlets ent1-ent16 of a two section crossbar multiswitch MS1, MS2 while links ml1-ml8 to the next switching stage extend from outlet levels NH1-NH8 theroef. Outlet levels NH9 - NH11 are reserved for loop testing and they are separated from the link outlet levels by saturable core transformers TR1-TR16 inserted in the inlet multiples. The latter are split between levels NH10 and NH11 to assist in the discrimination between the loop conditions. If the handset of line lg1 say, is on hook, contacts ct1 ct2 are closed so that battery and earth are connected to the unlooped a and b wires while all other contacts of selector SL1 are open. Scanning pulses from EXL applied to primary winding ene of transformer TR1 induce similar pulses in secondary winding ens to indicate that the line is unlooped. If the line is now looped, TR1's core becomes saturated whereby the pulses in ens cease and consequently central control causes the line to be connected through to a free link say ml1 by closing contacts ct5, ct6. At the same time contacts ct1, ct2 open to unsaturate the core but the recommencement of pulses from ens is no longer construed by central control as an indication that the line is free. At the end of the call and assuming that the called party hangs up first, contacts ct5, ct6 are opened while contacts ct3, ct4, ct7 are closed. Consequently battery and earth are connected to the looped a, b wires so that the pulses from ens are again inhibited and a warning tone from howler ton is induced in the line wires. In addition pulses from scanner EXC are now returned to the central control since ct7 is closed whereby a permanent loop condition is recognized. When the handset is replaced, the presence of pulses from both EXL and EXC indicates that the selector may now be fully released viz contacts ct1, ct2 closed and all the other contacts open.

Title: Process for the production of crosslinked acrylated copolymers
IPC: C08F220/12
Filed: 1968-06-14
Abstract: An acrylate copolymer is produced by copolymerizing an acrylate ester in the presence of a catalyst and a cross-linking agent containing two unconjugated polymerizable double bonds and having the formula in which A represents an aromatic or cycloaliphatic radical, X represents an alkenyl radical containing a terminal olefinic unsaturation or has the same meaning as Y, Y represents a radical of the formula in which each R, which may be the same or different, represents a hydrogen atom or a C 1 to C 6 -alkyl radical and R1 represents a carboxyl, alkoxycarbonyl, cycloalkoxycarbonyl, phenoxycarbonyl, chlorocarbonyl, carbamoyl, or cyano radical, Z represents a C 1 to C 6 - alkyl radical or a halogen atom and n represents 0 or an integer of from 1 to 4. Specified acrylates are methyl, ethyl and phenyl acrylates. Suitable cross-linking monomers are p- and n-vinyl cinnamic acids, p- and m-isopropenyl cinnamic acids, benzene - bis - 1,4 - or - 1,3 - (beta-acrylic acid), diphenyl-bis-2,21-(beta-acrylic acid), diphenyl methane-bis-4,41- (beta-acrylic acid), naphthalene - bis - 1,4-, - 1,3 -, - 1,5, - or - 2,6 - (beta-acrylic acid) and esters and nitriles thereof. An additional cross-linking agent such as divinyl or trivinyl benzene or divinyl toluene, xylene or naphthalene and further monomers may be incorporated in the copolymer. In the examples, methyl acrylate and, in some cases divinyl benzene are copolymerized with benzenebis-1,3-(beta-acrylic acid methyl ester), benzene-bis-1,4-(beta-acrylic acid methyl or nbutyl ester) or benzene-bis-1,4-(beta-acrylonitrile) in aqueous suspension. The resulting bead copolymers are hydrolysed with NaOH/ MeOH. The copolymer containing benzenebis-1,4-(beta-acrylic acid n-butyl ester) is reacted with 1-amino-3-dimethyl-aminopropane.

Title: Apparatus for treatment of fabrics with liquid ammonia
IPC: D06B7/08
Filed: 1970-05-06
Abstract: A machine for treating fabrics with liquid ammonia to improve their stretch and resistance to shrinkage and creasing comprises a chamber, a first feed means for feeding fabric into the chamber means in the chamber for impregnating the fabric with liquid ammonia, a second feed means for removing the fabric from the chamber and means between the first and second feed means for controlling their relative speeds and thereby applying a controlled longitudinal tension to the fabric. In the form shown the chamber is divided by partitions 50, 52 into three compartments A, B and C. In compartment A, the atmosphere of which is saturated with ammonia from a liquid ammonia trough 134 heated by steam lines 136, 138, the fabric passes under a roller 116 in a liquid ammonia trough 112 and is thereby saturated with liquid ammonia. The saturated fabric is then looped around guide rolls 84, 86, 94, 96, the number of such rolls employed governing the time of residence of the fabric, and then passes through sealing nip rolls 160, 162 into compartment B. Here the fabric is stretched transversely in a tenter machine 164 and is then heated by passing around heater drums 176, 178, 180 and 184. The atmosphere in B is saturated with ammonia vapour from a liquid ammonia trough heated by steam lines 170, 172. The fabric leaves compartment B through sealing nip rolls 240, 242 and passes into compartment C wherein it passes around guide rollers whilst being subjected to steam jets to remove the residual ammonia. The fabric passes from the chamber through sealing nip rolls 312, 314, 316, 318 and enters drive rolls 324, 326 whence it passes over another tentering frame 340, being first sprayed with water, if necessary, to allow tentering, and then around the dryer drums 344, 346 on which it is held by a felt 348 which preserves its stretched width whilst drying and is finally wound on to a take up roll 402. Optionally a compressive shrinker may be located between the tenter and the drying drums (Fig. 1C not shown). The longitudinal tension in the fabric as it enters compartment A is controlled by adjusting the speed of feed rolls 24, 26 relative to the speed of rolls 106, 108, the speed of the motor driving roll 24 being controlled by a rheostat, the setting of which is determined by the position of a roll 20 mounted on a pivoting lever arm 34, the arm actuating an air valve for a pneumatic cylinder 42 the piston of which actuates the rheostat. Similarly, movable tension roll 118 regulates the tension in the fabric between rolls 106, 108 and the heated drums in B, and movable tension roll 202, by controlling the speed of the take-up roll, regulates the tension between the heated drums and that roll. Means are provided for venting the compartments and preventing escape of ammonia therefrom. Furthermore the fabric may be saturated with a resin precondensate as well as the ammonia liquid in trough 112, the resin being cured in compartment C.

Title: Vapor phase resin fixation process for cellulosic material permitting subsequent cure
IPC: D06M15/423
Filed: 1971-03-17
Abstract: Improved crease resistance and smooth drying characteristics are imparted to cellulosic fiber-containing materials, such as cotton fabric, with a minimum sacrifice in physical properties by a process including (1) applying an aqueous solution comprising at least one water-soluble polymer-forming compound possessing reactive N-methylol groups and a latent curing catalyst to the cellulosic material, (2) exposing the material in a water swollen state in the presence of formaldehyde to a reactive vapor atmosphere containing a gaseous acidic catalyst such as sulfur dioxide, and (3) drying the material in preparation for the manufacture of a durable press article therefrom. The latent curing catalyst is conveniently applied to the material from the same bath as the polymer-forming compound, but as an alternative it may be applied to the material from a separate bath, e.g., after the reactive vapor treatment and prior to the final cure. The durable press article may be made by first making the dry uncured material into an article such as a garment having hot pressed creases therein and then curing the article (delayed cure), or by first curing the material and then making the cured material into a final product (precure).

Title: Treatment of vulcanized rubber
IPC: C08J3/12
Filed: 1974-07-16
Abstract: The invention provides finely divided vulcanized rubber having a particle size of generally less than 20 microns for re-use in the rubber industry. Vulcanizates produced from compositions containing the finely divided vulcanized rubber, either as the sole rubber component or in admixture with unvulcanized rubber, have properties significantly better than those of vulcanizates of similar compositions containing conventional reclaimed rubbers. Vulcanized rubber is converted into the finely divided rubber by the steps of (1) contacting vulcanized rubber with a fatty acid, (2) contacting the product of step (1) with a solid alkali and (3) forming a dispersion of the product of step (2) with a liquid which dissolves the alkali but does not affect the rubber. Alternatively, the finely divided vulcanized rubber results from the steps of (1) contacting the vulcanized rubber with a liquid effective to swell the rubber and thereby weaken it e.g. tetrahydrofuran, (2) comminuting the weakened material and (3) removing the liquid from the comminuted material.
