Title: Methods for making composite electric circuit components
IPC: H05K3/46
Filed: 1956-11-15
Abstract: An electrical unit is prepared by building up a plurality of layers of materials by depositing suspensions thereof in a suspending medium first upon a base member and then upon one another, hardening each layer while retaining therein sufficient medium to prevent the occlusion of gases, and bonding the particles of the composite body so formed to one another.  The units so formed include capacitors, inductors, resistors, thermistors, printed circuits and may include materials having desirable magnetic properties, e.g. ferrites.  The base material may be paper, cloth, synthetic resin, rubber, ceramic or metal, and may either be temporary, to be stripped or burned off after the unit is built up, or permanent.  The suspensions may consist of vitreous enamel or synthetic resins, e.g. phenolformaldehyde, vinyl, acrylic, polyamide, polystyrene or PTFE resins, or conducting substances such as gold, silver, rhodium, palladium, platinum or carbon.  A final firing or baking process converts the layers into a unitary whole.  The liquid content of each layer may be reduced after it has been deposited by applying absorbent paper or the like to the surface, and, if the base material is porous, by passing hot air in contact with the outside of the base.  The dispersions may be applied from a hopper and spread with a knife.

Abstract: 779,612. Valves. BRITISH THERMOSTAT CO., Ltd. Nov. 23, 1955 [Dec. 3, 1954], No. 35107/54. Class 135. In a fluid metering. device comprising a stem 6, Fig. 1, having an external helical groove, the stem being axially movable in a sleeve 7 integral with the body 3 of the device, the lower end of the stem is provided with a valve closuremember 5 co-operating with a valve seat 4 at the inlet port, the member 5 being urged towards the fully closed position by a spring 11, which valve can only move to this position after the stem 6 has been moved into the position giving minimum flow. A constant-level fuelchamber 1 is connected by an inlet pipe 2 to the base of the body 3 from which point flow to an outlet pipe 8 and burner 9 is controlled by the closure member 5. A spindle 10 upstanding from the stem 6 can have an operating member attached thereto whilst the spring 11 around the spindle is confined between the upper end of the stem 6 and an extension 13 of a bush 14 coaxially disposed in the upper portion 15 of the body 3 and retained in position by a spring clip 16 in opposed slots 17 in the portion 15, which clip is readily removed to facilitate cleaning of the valve assembly.

Filed: 1961-09-29
Abstract: 971,412. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Sept. 29, 1961 [Dec. 1, 1960], No. 35249/61. Drawings to Specification. Heading H4K. In a system in which a communication is established over a path comprising a series of transistor gates, the types of transistor and the control currents for them are so chosen that the latter flow in closed D.C. loops thereby preventing the appearance of D.C. or A.C. switching signals on the communication path. The invention is described with reference to a " resonant transfer " type of time division multiplex switching system using symmetrical transistors, alternate switches being of the NPN and PNP types. Since the control currents applied to these switches are of opposite sign, if these are made equal, then the combined effect of two such adjacent switches is to produce no charge on the highway. In a system using four gates for a connection between two subscribers the transistors might thus be connected in symmetrical fashion, e.g. in the order NPN, PNP, PNP, NPN. If the systems use 3 gates the central gate should either take twice the control current of the others or alternatively two similar transistors connected in tandem should be used. If the systems use 5 gates the central gate should consist of two dissimilar transistors connected in tandem. Specification 904,232 is referred to.
Patent GB-845405-A (GB)
Title: Improvements in or relating to throttle control systems for engines driving forward and reverse gears
Inventor: MARKHAM BASIL GERVASE
IPC: B63H21/22
Filed: 1955-12-09
Abstract: 845,405. Reverse gear control. BRISTOL SIDDELEY ENGINES Ltd. Nov. 22, 1956 [Dec. 9, 1955], No. 35385/55. Class 80 (2). In engine-driven reversing gearing having forward and reverse clutches and a manual throttle control, means are provided for delaying the response to the throttle control until either of the clutches is engaged. In a marine reverse gear, wherein an engine drives a screw-propeller through an epicyclic reverse-reduction gear having hydraulic clutches or brakes, the manual throttle control 10 rotates a bell-crank lever 11 rigid with a shaft 16 actuating two supply valves 17, 18, the former 17 controlling the supply of oil to either of the clutch-operating pistons 19, 20. The valve 18 controls the supply of oil to a pressure equalizing duct 23 and a restrictor 26 leading to the ends of a servovalve 15 controlling the admission to a servopiston 13, rigid with engine throttle linkage 14, through a duct 24. The piston 13 is urged towards a throttle closed position by a spring 21, in a space 21 free to atmosphere through bleed hole 71. A rocking arm 12 is connected at its ends to the piston 13 and valve 15, and at its centre to a link 70 connected to the bellcrank 11, the linkage being arranged that when the lever 10 is in the neutral position the link 70 is in line with the arm of the bell-crank 11. When the lever 10 is moved from neutral to ahead position, the shaft 16 is rotated to move the valve 17 to supply pressure oil to the ahead clutch and also to cause valve 18 to supply oil to the restrictor 26. Throttle movement is also transmitted to the arm 12 to move the servovalve 15 to the right and allow the passage of oil through the restrictor to the piston 13 to open the engine throttle, the build-up of pressure on the piston 20 being rapid while the restrictor 26 delays the build-up on the throttle opening piston 13. Displacement of the piston 13 moves the rocking arm 12 about its pivot on the link 70 to move the valve 15 to the left until it reaches its equilibrium position when it closes the duct 24. Movement of the lever 10 to shut the throttle causes the valve 15 to move to the left to vent the piston 13 through duct 24 and drain 25, and the piston 13 is moved to the left by the spring 21 until equilibrium at the desired throttle setting is again obtained. If, when either clutch is engaged, the oil pressure should drop, the reduction of pressure on the piston 13 allows a ball-check valve 27 to open to release the pressure on piston 13, and the spring 21 operates to close the throttle. A collar 33 on the link 14 forms with the levers 34, 35 and adjustable slowrunning stop whereby the throttle may have limited opening for inspection or testing purposes.

Filed: 1936-12-24
Abstract: 479,631. Glass manufacture. CORNING GLASS WORKS. Dec. 24, 1936, No. 35418. Convention date, Dec. 30, 1935. Drawings to Specification. [Class 56] A method of stabilizing the molecular arrangement of annealed glass articles, particularly thermometers, consists in maintaining an article for a relatively short time at a temperature substantially higher than the maximum temperature to which the article will be subjected in service but below the strain temperature of the glass. The treatment may be applied to a thermometer adapted for use up to 360‹ C. and having the glass of its stem composed of 61À9 per cent of silica. 0À2 per cent of boron trioxide, 1À9 per cent of alumina, 10À9 per cent of sodium oxide, 1À0 per cent of potassium oxide, and 24 per cent of lead oxide, while the bulb is composed of 68À8 per cent of silica, 2À3 per cent of boron trioxide, 1À5 per cent of alumina, 14À7 per cent of sodium oxide, 5À7 per cent of calcium oxide, and 7À0 per cent of zinc oxide. Compositions of other glasses with their strain temperatures and expansion coefficients are given in the Specification. The thermometer is subjected to a temperature of 505‹ C. near the strain temperature of the glass of the bulb, and is maintained at this temperature for a relatively short time. It is then maintained at successively lower temperatures for relatively longer times until the temperature is near the strain temperature of the glass of the stem where it is again held for a relatively short time. Again it is maintained at successively lower temperatures for relatively longer times until the temperature is near the highest temperature to which it will be subjected in use, and after treatment at this temperature it is brought to room temperature.

Title: Improvements in or relating to gas chromatography

Filed: 1967-09-30
Abstract: 1,240,121. Gas chromatography apparatus. PYE Ltd. 24 Sept, 1968 [30 Sept., 1967; 25 July, 1968], Nos. 44629/67 and 35661/68. Heading B1L. [Also in Division G3]. Separate traps in trap unit TU are presented to the outlet of gas chromatograph column C to isolate desired fractions, the trap changing mechanism being controlled by means of a predetermined punched tape programme in conjunction with means for comparing the output signal of detector D with a reference level, preselected for low, medium or high settings by means of microswitches MS1-3 in pen recorder PR. Trap index controller TC comprises a number of banks of switches (S1A to S6C), any one of which may be selected in sequence by solenoid actuator SA which is advanced by closing selector advance microswitch MS5; when a sample is injected on to the column, sample inject microswitch MS6 is operated and solenoid actuator SA is returned to the first bank of switches. Switches SID to S6D select the operative bank of switches S1A to S6C, so that when (as shown) S3D is selected as well as one of the other switches S3A-C in bank 3, and solenoid actuator SA also selects bank 3, the upper pole of S3D opens to disconnect power supply from the tape drive motor M while its lower pole closes. As a result, solenoid actuator SA advances to the next bank, and motor M restarts, but only when the pen of recorder unit PR passes the low, medium or high level which has been selected, effluent from the column C meanwhile passing into a stationary trap. The trap is switched when solenoid actuator SA is energised by pen recorder PR and passes to the next selected bank. In this way, collection of desired fractions of a chromatogram may be isolated in separate traps, undesired fractions being allowed to pass to waste, and it is also feasible to synchronise the tape and chromatogram at the leading or trailing edge of an unambiguous peak. In the latter case, one may thereby isolate in higher concentration a minor fraction whose elution overlaps with that of a major fraction (see Fig. 2, not shown). In an alternative embodiment (see Fig. 3, not shown), trap index controller TC is replaced by a comparator circuit in which the signal from the detector D is compared with the signal level selected from any one from a group of potentiometers, a relay being operated when the selected level is reached which operates the trap changing mechanism.

Title: Improvements in or relating to the manufacture of films, sheets and the like from cellulose nitrate
IPC: C08L1/08
Filed: 1929-11-25
Abstract: Homogeneous films or sheets are prepared by spreading on a suitable surface a solution in a volatile solvent of a cellulose nitrate of low viscosity and having a nitrogen content of less than 11,35 per cent, e.g. 10,7 to 11,35 and preferably 11 per cent.  The viscosity is preferably 10,75 seconds, as determined by the fall of a steel ball 3/32" diameter through 11,44" of a solution formed by dissolving one part of the nitrate in 9 parts of a mixture of 199 DEG  proof ethyl alcohol and acetone, the solution being maintained at 20 DEG C.  The low viscosity nitrate is preferably prepared by treating cellulose nitrate with hot water under pressure with or without catalysts. Suitable solvents are acetone alone or mixed with ethyl or methyl alcohol, or a mixture of ethyl or methyl alcohol with ether. Plasticizers, e.g. camphor, diethyl phthalate or dibutyl phthalate may be added, e.g. 40-50 per cent; and stabilizers, e.g. urea may also be present.  Concentrated solutions may be employed to obtain thick films, e.g. 0,015".  The films or sheets may be moulded or embossed and are readily cemented to other surfaces.  They are particularly applicable as photographic films and in the making of reinforced glass.  In an example a solution is made up of cellulose nitrate, of 11 per cent nitrogen content and 15 seconds viscosity, 100 parts, camphor 50 parts, urea 1 part and acetone 400 parts by weight.  The solution is flowed on to the rim of a slowly rotating large wheel and the acetone is caused to evaporate by exposure to the air.
