Title: Improvements in and relating to regulators for electrical discharges
IPC: H05G1/34
Filed: 1923-12-04
Abstract: 210,743. British Thomson-Houston Co., Ltd., (Assignees of Coolidge, W. D.). Jan. 30, 1923, [Convention date]. Thermionic valve circuits.-A discharge tube operated by variations in current or voltage automatically regulates the current in a circuit, such as the space current in a R÷ntgen-ray or thermionic tube, by varying the supply voltage so as to oppose the variations in current or voltage. In the arrangement shown a high vacuum R÷ntgen-ray tube 2 of the type described in Specification 14892/13, [Class 39 (i), Electric lamps, Arc &c.], is supplied through a transformer 7 the secondary winding of which includes the primary of another transformer 20, with a secondary supplying current to the cathode 18 of the control tube 17. The cathode 3 of the tube 2 is supplied through a transformer 14 the primary of which is connected across the mains through an impedance 26 such as a reactance or an iron wire in hydrogen. The voltage across the anode 19 and cathode 18 is supplied by a transformer 23 connected through the impedance 26 with the mains. The voltage across each tube is sufficient to produce saturation. When the space current in the tube 2 rises above a predetermined value an increase in the heating current of the cathode 18 and, consequently, a magnified increase of space current in the tube 17 are produced. The increase in current thus drawn from the mains through the impedance produces a fall in the voltage across the transformer 14, and a reduction in the heating current of the cathode 3, so that the space current through the tube 2 is brought back to the normal value. Conversely an initial decrease in the space current is compensated by an increase in the cathode heating current. In a modification the primary of the transformer 20 is connected on the cathode side of the secondary of the transformer 7, and the transformer 14 is inserted at a point between the transformer 23 and the impedance. A variable resistance may be connected in parallel with the cathode 18. In another modification variations of voltage supplied from the mains to the tube 2 are compensated in a similar way by an additional control tube, the cathode of which is supplied from a transformer connected through impedances across the mains. In a further arrangement the transformer 20 has an air gap and two primary windings, one connected across the mains and supplying most of the heating current, and the other connected with the secondary of the transformer and supplying the variable component, the secondary being connected with the cathode 18 as shown.

Abstract: 1533796 Artificial leg with polycentric knee joint CHAS A BLATCHFORD & SONS Ltd 20 Oct 1977 [22 July 1976] 30622/76 Heading A5R An artificial leg comprises a polycentric joint knee mechanism formed of a multipivot linkage whose instantaneous centre of rotation at full extension of the leg, i.e. the initial instantaneous centre of rotation, is adjustable in height and lies above the knee centre i.e. the notional stationary centre of rotation about which the leg can be demonstrated to have flexed, at the end of 90‹ of flexion from the fully extended position. The knee mechanism may comprise a 6- bar linkage or, as shown, a 4-bar linkage 1-4 whose initial instantaneous centre of rotation C 0 , Fig. 6, can be varied by altering the length or position of at least one of the links, e.g. by providing a rotatable eccentric pivot. Alternatively it can be varied by an adjustable extension stop which limits the mechanism movement. Such extension stop may be incorporated in a known swing phase coupling 6. The instantaneous centre of rotation is located at the intersection of the projections of links 2, 4.

Abstract: 1,215,567. Pulse frequency discriminators. FERNSEH G.m.b.H. 18 June, 1969 [4 July, 1968], No. 30789/69. Heading H3P. A circuit for detecting whether a pulse train is above or below a critical frequency comprises a pulse lengthener 2, 5, 7 followed by a pulse width discriminator 9 which passes only pulses whose width is greater than a single lengthened pulse, the input pulse train and the output from the discriminator 9 being fed to an AND gate 11. If the output from discriminator 9 is fed directly to the AND gate 11 only pulses below a predetermined spacing are passed to the output. If an inverter (13, Fig. 3, not shown) is included only pulses above the predetermined spacing are passed. As described capacitor 4 charges between pulses to produce a sawtooth whose amplitude depends on the spacing. If the spacing exceeds the predetermined value the threshold 5 passes this sawtooth to Schmitt trigger 7 to produce lengthened output pulses. If the pulse interval of the input pulse train is less than the limiting value, the pulses from 7 merge into a single pulse which is detected by discriminator 9 to produce the required control signal for gate 11.

Title: Improved method for impregnating and/or coating fabric with rubber
IPC: D06M15/693
Filed: 1928-10-25
Abstract: 324,664. Dunlop Rubber Co., Ltd., and Trobridge, G. W. Oct. 25, 1928. Waterproofing; proofing processes and compositions; single coatings.-In a process for coating fabric with rubber from aqueous dispersions thereof, with or without impregnation, the fabric, prior to dipping into aqueous dispersions containing rubber, is wetted with an agent such as water or stabilizing solutions such as ammonia to assist the penetration of the dispersion, or with an agent such as a volatile coagulating or dehydrating agent to limit the penetration of the dispersion into the fabric. The fabric may be placed upon moulds or formers, or may be caused to travel over a stationary or travelling band partially immersed in the aqueous dispersion. The final setting of the deposit of rubber is effected by setting or coagulating means, as for example, by heat, by dehydrating and setting solutions as described in Specification 303,544, [Class 70, Indiarubber &c.], or by acid coagulating solutions such as acetic acid solution. The formers may be porous or non-porous, or may be of glass. metal, or porcelain containing perforations and provided with a. covering of porous material such as fabric or gypsum. The aqueous dispersions of rubber may be compounded, preserved, natural or artificial, vulcanized or unvulcanized, and may contain added substances such as factice, rubber waste, rubber reclaim, mineral or synthetic rubber, vulcanizing agents, accelerators, preservatives, dyes and fillers. Artificial resins may also be mixed therewith. Concentrated compounded dispersions obtained by the process described in Specification 290,313, [Class 70, Indiarubber &c.], are particularly suitable. A suitable dispersion consists of 100 parts of rubber as latex, two parts of sulphur, 5 parts of transformer oil, and 1 part of zinc diethyldithiocarbamate. In carrying out the invention, a metal former of the shape, for example, of a glove, is covered with a fabric glove. The fabric is wetted with water or with ammonia in order to assist penetration by the dispersion, and then dipped into an aqueous dispersion for about ten seconds. When it is desired merely to coat and not to impregnate the fabric, the latter is wetted with a volatile coagulant or dehydrating agent such as acetone, alcohol formaldehyde or formic acid solution. The coated fabric is dried and vulcanized in the usual way and then stripped from the former. Thicker coatings may be obtained by repeating the dipping. Specification 309,391 also is referred to.

In the form shown in Figs. 1, 2 and 5, the shuttle, of trapezoidal cross-section, has a slot 12 for receiving the weft-gripping springs 13 and reinforcing springs 13<1> and is slotted at 8 to form branches 9, 10. The branch 10 has a beak 15 overhanging the slot 8 and a curved deflecting-surface 3<1>, while the branch 9 has a deflecting-surface a and a bevelled part 2<11> for leading the weft 18 from a guide 19 into the slot 8 and thence between the spring clips 13. The weft is held, and, in some cases cut, by a notched guide 6<11> carried on a spring arm 21 which embraces the warps at the edge of the fabric and is moved towards the fell at the beat-up. In a modification, the slot 12, Fig. 18, is formed at an angle to the central plane of the shuttle, the weft 18 being depressed by a finger 22 to enable it to enter the slot. In another form, the projecting branch of the shuttle has a warp-deflecting surface on each side. The shuttles may be curved to adapt them to circular looms.
