Title: Improvements in mechanical relays of the fluid jet type
IPC: F15B9/06
Filed: 1940-09-30
Abstract: 572,631. Fluid-pressure servomotor-control systems. BRAITHWAITE, R. C., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Sept. 30, 1940, No. 14724. [Class 135] A fluid - pressure servomotor having a jet-type controller has the transmitting nozzle and receiving orifice of the controller carried by a piston operating a relay valve so as to " follow-up " the movement of the controlling deflector working between the nozzles. A further '' follow-up " is obtained by coupling the casing housing to the relay valve and' supporting the transmitting nozzle and receiving orifice to the main power piston. The transmitting nozzles 1 and receiving nozzle 2 are mounted in arms 3, 4 on a carriage 5 secured by screws 7 to a differential 8 working in a piston cylinder 9 in a casing 10. Fluid under pressure from a pipe 13 is admitted to a chamber 11 between the differential heads 21, 22 and passes by way of passage 14, thimble 15 and pipe 17 to the nozzle 1. Fluid received by the nozzle 2 passes by way of passages 20 and 19 and central bore 18 in the piston, restricted by a capillary tube 23, to a chamber 12. When a controlling deflector (not shown) moves to deflect more or less of fluid issuing from the nozzle 1 away from the nozzle, the variation of pressure in the chamber 12 moves the piston and carriage in the sense to follow the movement of the deflector and at the same time moves a piston relay valve to direct pressure fluid entering by the pipe 25 to one of the pipes 26, 27 leading to the main power device. Movement of the main power device slides the casing 10 in a fixed base-plate relatively to the controlling deflector to provide a secondary follow-up. The carriage 5 is connected to the relay valve by a ball attachment 28 lapped with minimum clearance in a slot 29 in a projection 30 on the valve, any small clearance being taken up by a leaf-spring 31.

Title: Controlling Tube Current and Anode Voltage of an X-ray Tube
Inventor: BRANDELIK SANDOR
IPC: H05G1/30
Filed: 1967-03-31
Abstract: 1,173,967. Controlling X-ray exposures. MEDICOR MUVEK. March 31, 1967 [April 7, 1966], No. 14943/67. Heading G1A. The current in a radiological X-ray tube is optimized by scanning the fluorescent picture produced, integrating a signal indicative of the luminosity over those areas which the presence of high frequencies in the scanning signal shows to contain most detail and adjusting the tube current until the integrated signal has a predetermined value. The tube anode voltage is adjusted to mascinize the high frequencies in the scanning signal and consequently the amount of detail in the picture. The output of a photo-electric cell 3 or television camera scanning the fluorescent picture 2 is fed through a gate 5 to an integrator 6 and also directly to a selective amplifier 7 comprising a linear amplifier 11 and high pass filter 12 having a transmission capacity of which increases linearly with frequency. The amplifier output is fed to a pulse forming circuit 10 which opens the gate 5 when the R.M.S, value of the A.C. component of the scanning signal is above a predetermined level. The output of integrator 6 may automatically adjust a potentiometer 19 varying the current through the tube 1 until the integrator output reaches a preset value. The R.M.S. value of the amplifier output is also derived by a rectifier 8 and differentiated by a circuit 21 which adjusts the tube anode voltage by means of a potentiometer 25 until the derivitive is zero. The amount of detail in the picture is then a maximum. The circuit 21 and the potentiometers 19, 25 may be omitted and the tube current and voltage adjusted in accordance with the readings on indicators 14, 15.

Title: Improvements in or relating to jet propulsion nozzles
IPC: F02K1/46
Filed: 1959-05-01
Abstract: 885,093. Jet propulsion nozzles. YOUNG, A. D. April 26, 1960 [May 1, 1959], No. 15038/59. Class 110 (3). A jet propulsion nozzle has mounted substantially radially thereon, in the region only of the exit, a plurality of vanes which in an operative or noise suppressing position are inclined over a major portion of their length and in non- stalled relationship to the general fluid flow through the nozzle. In cases where the vanes are mounted for oscillation, the maximum angle the vanes make with the general fluid flow direction is such that the vanes are in non- stalled relationship to the fluid flow. The jet pipe nozzle 2, Fig. 1, has vanes 1 which project into the jet flow and are inclined along the whole of their length to the general direction of this flow. In a modification the nozzle also has vanes on its outer periphery inclined in a different sense from those on the inner periphery. The inner and outer vanes may be in line or displaced circumferentially relative to one another. In a further modification the angle of inclination of the inner and outer vanes is adjustable. In another modification the outer vanes are provided with a perforated shroud. The inner and outer vanes may also be twisted in opposite directions. In a still further modification, Fig. 9, the vanes 1 are pivoted on pins 7 and a coil spring is attached to the lugs 8 and pins 7. The vanes can oscillate between inclined angles on either side of the mid-position shown in full lines. The oscillation of the vanes induces corresponding oscillations in the flow direction of the jet gas and this prohibits the formation of regular annular vortices which cause noise. The vanes may extend downstream of the jet pipe nozzle.

Title: Improvements in and relating to the concentration of latex
IPC: C08C1/12
Filed: 1934-05-18
Abstract: A process for the evaporative concentration of latex and other rubber dispersions to obtain a concentrate of liquid nature having a dry rubber content above 55 per cent comprises adding organic water soluble or dispersible protective colloids not precipitable by weak alkalies in amounts not exceeding 2 per cent by weight of the dry rubber content of the latex, subsequently removing part of the aqueous content by evaporation and ceasing the evaporation while the latex is still liquid but has reached the desired concentration. Protective colloids specified are triethanolamine or ammonium caseinate; triethanolamine, ammonium, potassium or sodium stearate; glue; gelatine; soluble albumens; and Lissapol A ("Lissapol" is a Registered Trade Mark).  When ammonia preserved latex is concentrated further quantities of ammonia may be added to the latex during the operation when such is accompanied by loss of ammonia; alternatively the latex may be stabilized by less volatile alkaline stabilizers such as caustic potash or triethanolamine.  The latex prior to the concentration may be purified by dialysis to remove some or all of the water soluble impurities, for example, by the process disclosed in Specification 430,426.  According to the Provisional Specification the amount of protective colloid is not limited to 2 per cent and the protective substances may be those present in the latex itself.

Abstract: 560,879. Surgical dressings &c. RYCO LABORATORIES, Inc. Oct. 30, 1942, Nos. 15315, 15316 and 15317. Convention dates, Oct. 11, 1941, Aug. 22, 1942, and Sept. 1, 1942. [Classes 81 (i) and 81 (ii)] A surgical dressing comprises a wet pad 1 of gauze, lint, &c., saturated with a composition containing glycerin, an anµsthetic and an antiseptic substance, and hermetically sealed within an impervious envelope 2, e.g. of rubber hydrochloride. In use, the envelope 2 is cut or opened by a rip-cord, the pad extracted and applied to the wound, burn, &c., being then covered by the outer envelope and held in place by bandages. The dressings may be made by placing saturated pads at spaced intervals between two webs of rubber hydrochloride, heat-sealing the webs together around the pads, e.g. at 3 and 5, and then cutting the individually sealed packages apart. In a modified form, the envelope 2 is attached to an adhesive backing 8, Fig. 8, the adhesive 9 being protected, before use, by layers of fabric 10, 11. To use the dressing in this form, the layers of fabric 10, 11 are removed, the envelope 2 opened along the line 12, the pad removed and applied to the wound, burn, &c., the envelope placed over the pad and the whole held in place on the patient by the adhesive backing 8. The pad may be formed so that it can be opened to cover double its-original area before applying the adhesive backing over it. Examples of the anµsthetic and antiseptic substances used are chlorbutanol, benzyl and salicylic alcohols, quinoline and piperidine derivatives, &c., and sulphanilamide, boroglycerin, &c. The preferred saturating composition is, by weight, as follows :-sulphanilamide 7, chlorbutanol 5, oxyquinoline sulphate 2, boroglycerin 21 and glycerin 65 parts. This composition may be applied to the pad as a salve absorbed in diatomite, kaolin, &c.

Title: Difference pulse code modulation translator
IPC: H04B14/06
Filed: 1975-04-14
Abstract: 1494282 Differential pulse code modulation WESTERN ELECTRIC CO Inc 14 April 1975 [18 April 1974] 15321/75 Heading H3H In difference pulse code modulation encoding or decoding the difference pulse coded signals are accumulated to produce a feedback or reconstructed analogue signal and the algebraic sense of the difference pulse coded signals is changed whenever the polarity of the feedback or reconstruction signal changes so that tracking errors are wiped out as the feedback or reconstruction signal assumes a level next to the reference level and approaches the reference level from the opposite direction to that from which the true feedback or reconstruction signal would have approached it. In Fig. 1, encoder 10 comprises a subtraction circuit 18, D-type flip-flop 19 which outputs a delta bit stream, reversible binary counter 20 for doing the accumulation and D-to-A converter 22 for providing the feedback signal. The most significant, sign, bit in counter 20 controls EX NOR gate 28 for changing the algebraic sense of the delta bits. Gates 26, 27 detect over- and under-flow respectively and force flip-flop 19 to output 0 or 1 respectively at the next C1 clock time, thus preventing overload. Decoder 12 is similar to the feedback loop of the encoder, EX NOR gate 31 preceding the D-type flip-flop 32. In a modification, Fig. 2 (not shown), the EX NOR gate precedes the flip-flop and the counter handles only magnitude bits, the polarity bit being held in a flip-flop (50). In multilevel differential pulse code modulation encoding or decoding, Fig. 7 (not shown), the counters of Fig. 1 are replaced by adders (91, 99) and registers (92, 95). In another form, Fig. 5 (not shown), an integrator (66) is included in the forward path between the subtraction circuit and the flip-flop, and the accumulation is done in a shift register (71) fed with 1's at one end and 0's at the other end and shifted by the delta bits, its parallel outputs going to a D-to-A converter thus producing shift-companding. The sign bit is handled separately in a flip-flop (82), controlling the algebraic sense of the delta bit stream through NAND gates (68-70) which also respond to over- and under-flow of the accumulating shift register.
