Title: Improvements in or relating to fluid pressure engines, pumps or the like and to control arrangements therefor
IPC: F04C14/22
Filed: 1947-04-30
Abstract: 623,327. Rotary engines. HYDE, J. E., and DOLPHIN INDUSTRIAL DEVELOPMENTS, Ltd. April 30, 1947, No. 11561. [Class 110(ii)] A toggle mechanism is used to vary the eccentricity between the rotor 1 and its casing 3. The latter is moved up or down in accordance with the hydraulic pressure acting on a piston 29 in a cylinder 30 or the restoring action of springs 41, these forces acting through links 20, 21, 24, 25 formed as a toggle mechanism. The casing 3 has a guide piece 10 which slides vertically in guides 11, 12 and has a projection 18 which is pivoted at 19 to levers 20, 21. The rotor is driven by a .sprocket 2 and carries sliding or other type vanes. The casing is supplied with oil from a delivery 8 and passage 9. Fig. 4 shows a modification in which oil under pressure forces apart two.pistons 66, 67 to act through toggle links to vary the vertical position of a casing 47, Springs may be used to restore the position of the casing. The pump may be used in the hydraulic drive system of a vehicle. Oil is supplied to the centre of the cylinder 68 from the main oil line 71 through the vertical duct 72, oil being fed to the pump from the reservoir through a channel 73 or 74 according to the direction of rotation of the rotor and returned via a filter 75. The oil flow from the pump is controlled by a piston 77.

The drafting device comprises a pair of feed rollers 7, 8, one roller, preferably the driven roller 8 being corrugated, and the other roller 7 being a smooth resilient roller, e.g. having a rubber belt 9. The drafting device preferably comprises two such roller pairs, the resilient roller 11 of the second pair being provided with a doctor blade 14 to remove loose fibres. The false-twisted yarn produced is dried on the package 19. The yarn has a flattened crosssection and is suitable for use in weaving and knitting to produce waterproof and windproof fabrics, e.g. tent cloth.

The rings may have on their upper and lower surfaces complementary annular projections and recesses which may have inclined surfaces so that the distance apart of the rings can be varied by relative rotation. The rings may be threaded on to a refractory tube, or may be arranged so that hot gases can escape between them. Alternatively, the refractory tube may be perforated or made of porous material. In the forms shown in Figs. 10 and 11, the ends of the inner tubes 10a, 10b and 24, 25 are closed.

April 9, 1959 [April 10, 1958], No. 12035/59. Class [Also in Group XL (c)] A capacity measuring bridge is driven by an oscillator (see Group XL (c)), the arms of the bridge forming the capacity of the oscillator LC circuit. The bridge, Fig. 3, comprises capacitors C 1 , C 3 , C 4 , C x  across one diagonal of which is connected the inductor L. Referring to Fig. 1, the inductor is loosely coupled to a winding W 3  on the centre limb of transformer T. At its resonant frequency, the tuned circuit presents a high impedance across winding W 3  and the signals induced in grid windings W 12 , W 22  from W 11  are unequal, resulting in positive feedback from anode to grid at this frequency. At all other frequencies, the tuned circuit is effectively a short-circuit across W 3 , the voltages induced into W 12 , W 22  are therefore equal, resulting in no feedback. The other diagonals of the bridge are connected via an amplifier V to indicator I.

Abstract: 513,883. Statistical machines BRITISH TABULATING MACHINE CO., Ltd. April 22, 1938, No. 12164. Convention date, April 24, 1937. [Class 106 (i)] In card feeding and reading means for recordcard-controlled machines, a contact roller 20 coacts with a card hole reading brush 19, rollers 18 feed the cards to the contact rollers at one peripheral speed and the contact roller is driven at a higher peripheral speed through a friction clutch 20, 25, Fig. 2, which slips under the drag applied by the card and the reading brush. In this way the points of contact between brush 19 and roller 20 are constantly changing and prevent burring of the contact roller. The invention is applied to a sorting machine as in Specification 391,496. A worm 21 on the shaft 14 drives a wheel 22 rigid with shaft 23 together with an insulating bush 24. The reduced part of bush 24 is a free running fit inside the roller 20, but the annular surface 25 contacts frictionally with the end of roller 20 under the action of a spring 31 pressing against an insulating bush 28. This bush 28 fits tightly into roller 20 and fits tightly on to a metal bush 29 which runs freely on shaft 23. Roller 20 is of slightly greater diameter than rollers 18 but is retarded to substantially an equal peripheral speed when a card is being read.

Title: Process for printing textile materials
IPC: D06P5/15
Filed: 1953-05-04
Abstract: Discharge printing is effected on linear aromatic polyester textiles, e.g. polyethylene terephthalate textiles, by padding the textile with an aqueous dispersion of a dischargeable dyestuff, drying, applying locally a discharge printing paste and subsequently steaming, preferably at superatmospheric pressure. The discharge paste containing, for example, sodium or zinc formaldehyde-sulphoxylate may also contain dyestuffs, e.g. vat dyes, or dyestuff components which are not decomposed by the discharge agent.  Two or more discharge printing pastes may be employed and the process can be combined with a direct printing step to modify locally the ground or discharge shades.  In examples, polyester cloth is padded with an azo dye liquor containing an aqueous emulsion of sulphonated sperm oil and pine oil, sodium m-nitrobenzene - sulphonate and gum tragacanth, dried and printed with a zinc formaldehyde - sulphoxylate discharge paste containing p - hydroxydiphenyl, an aqueous emulsion of sulphonated sperm oil and pine oil, and gum tragacanth thickening together with, in one case, diethyl tartrate, and in another case, disodium dinaphthylmethane - disulphonate and a vat dyestuff.  In one example, the padded cloth is first printed with a vat dyestuff paste and then with the discharge paste.  The cloth is finally steamed, and when a vat dyestuff has been applied it is oxidized with aqueous nitrous acid, rinsed and dried.  Specifications 701,968 and 712,418 are referred to.

Title: Improved burglar alarm system
IPC: G08B13/22
Filed: 1950-05-17
Abstract: 693,630. Burglar alarm systems PRICE, A. B., and McKECHNIE, A. Aug. 17, 1951 [May 17, 1950], No. 12340/50. Class 118 (i). A burglar alarm system comprises a closed circuit detecting device and an open circuit detecting device, each associated with a relay, and a control relay, which are connected in a particular circuit arrangement whereby the control relay prepares the circuit of the open-circuit and closed circuit relays so that disturbance of either of the detecting devices causes an alarm to be operated. The Figure shows an alarm system in which the opening of normally closed contacts CC, or the closing of normally open contacts OC, both being contained in burglar detecting devices, causes an alarm WD to be operated. In setting the system, switch IS is closed to operate relays E/1 and F/1 to light lamps L connected across the main power supply. Remote control switch RCS is also closed to operate control relay C/2, which first closes contact Cl to operate relay A/3 and later closes contact C2 to prepare the circuit of relay B/4. Contact A3 releases relays E/1 and F/1 so that lamps L go out. If a burglar opens one of the contacts CC relay A' releases to operate relay B/4. The lamps L light and contact B3 operates alarm WD from a separate battery, which contact B2 holds relay C/2 operated even if the burglar cuts the circuit of the switch RCS. If the burglar closes contact OC, relay B/4 operates to energize the alarm. The alarm may. be discontinued by opening switch RCS and shorting the contacts CC with plug SP. Lamps L are switched off by opening switch IS. A bandit alarm switch BA is also provided for use when the normal burglar alarm is not operative. Relay D<SP>2</SP> is normally operated from transformer T to provide the system with power from the supply mains, but if these fail contacts D1, D2 substitute a battery PB1 as the power supply.
