Title: Artificial muscle with former allowing large chamber diameter with low volume of fluid
Inventor: MAJOE DENNIS
IPC: F15B15/10
Filed: 2009-11-05
Abstract: An artificial muscle comprises a variable volume flexible chamber 44, a system for varying the volume of and/or pressure in the chamber to inflate and deflate the chamber, and a tendon 18 for transmitting force and/or movement between the chamber and a load. In its deflated state, the chamber is wrapped at least partly around an elongate former 12. In its deflated state, the chamber can therefore have a substantial diameter but the volume of working fluid in the chamber can be very small or, in the limit, zero. The former might be a solid body contained within the chamber. Alternatively, the former is preferably outside the interior of the chamber. When the chamber is deflated, the tendon tension tends to pull the chamber neatly around the former.

Title: Improvements in or relating to the treatment of cellulose film
IPC: B01J19/12
Filed: 1961-03-20
Abstract: Regenerated cellulose film is subjected to ionizing radiation at a dosage of 103-107 rads., to effect cross-linking directly or indirectly between cellulose molecules.  The ionizing radiation is such that it is able to penetrate the film without inducing substantial radio-activity therein.  The radiation may be gamma-, betaor X-rays derived from, e.g. Co60, Cs137 or fission products of U235.  The dosage of 103107 rads., preferably 105-106 rads., is sufficient sufficient to induce cross-linking without causing substantial physical degradation as exemplified by loss of tensile strength.  The treated film may show reduced swellability in water, and increased dimensional stability and tear resistance. In the examples regenerated cellulose film 0.1 mm. thick is exposed to gamma radiation at a dosage of 1.1 x 105-3.3 x 105 rads.  Specifications 895,479 and 916,567 are referred to.

Title: Improvements in or relating to hydrofining cracked petroleum hydrocarbons
IPC: C10L1/06
Filed: 1953-04-14
Abstract: Cracked petroleum hydrocarbons boiling below 700 DEG F. are mildly hydrofined by contacting with added hydrogen in the presence of a hydrofining catalyst, at a temperature of 400-700 DEG F., a pressure of 50-250 p.s.i., a feed rate of 1-20 v.v./hr. and a hydrogen consumption of not more than .60 standard cubic feet per barrel; the bromine number is thus reduced by not more than 33 per cent. Catalysts specified are cobalt molybdate supported on alumina and a mixture of tungsten and nickel sulphides.  Dilute hydrogen from a hydroformer, containing for example 50-100 per cent hydrogen, may be used.  The treated hydrocarbons may be washed with caustic soda or steam stripped.  In examples, the hydrofining of thermally cracked virgin naphtha and of a catalytically cracked light naphtha of boiling range 130 DEG -330 DEG F. is described; mixtures of thermally and catalytically cracked naphthas may also be treated. Specification 711,259 is referred to.

Title: Substrate position determination structure and method
IPC: B23K26/38
Filed: 1972-03-06
Abstract: 1319045 Measuring displacement electrically MICROSYSTEMS INTERNATIONAL Ltd 6 March 1970 [3 Sept 1971] 10255/72 Heading G1N Means for accurately positioning a laser cutting beam or a spark discharge erosion beam relative to a sheet of substrate material comprises a resistive strip on the surface of the substrate which is progressively cut by the beam as it is moved from one edge of the strip to the other, whilst the resistance of the strip is being measured. When the resistance reaches a very high value the beam is at the remote edge of the strip and is stopped, defining a particular coordinate position of the cutting beam relative to the substrate surface. This is repeated in a perpendicular direction to determine a second co-ordinate position of the beam. As shown (Fig. 6) for cutting a substrate sheet 5 with respect to electronic circuits pivoted on it, a resistive strip 1 has its resistance measured between end pads 2, 2 by feelers 7, 7 whilst it is cut transversely by movement of a laser beam located in the area X, under the control of motor 11. When the measured resistance reaches a predetermined high value, the beam position defines a base co-ordinate distance along the abscissa direction of substrate 5. The beam is then moved by motor 12 in the perpendicular direction to the area Y and the process repeated for the stepped portion of resistive strip 4. The next stopping point defines the base co-ordinate distance along the ordinate direction of substrate 5. Hence the origin and co-ordinate directions for subsequent automatic movement of the cutting beam are accurately defined.

Title: Improvements in or relating to rotary pumps
IPC: F04C29/02
Filed: 1943-06-25
Abstract: 566,420. Rotary compressors. CURTIS PUMP CO. June 25, 1943, No. 10308. Convention date, Feb. 13, 1943. [Class 110 (ii)] A rotary sliding-vane compressor has means subjected to the discharge pressure for introducing lubricating oil to the working chamber at a point between the inlet and outlet ports, under a pressure which is between the suction and discharge pressures. The inner sides of the vanes 32 are acted upon by oil under pressure, the pressure in a chamber 38, opposite the discharge port 12, being higher than that in a chamber 41 under the remainder of the vanes. A discharge pipe 13 leads to a filter 14 containing a number of screens 15. Cleaned air passes to a reservoir 17 and oil, separated out, is led through a pipe 18 with coils 19, cooled by a fan 20, driven by a motor 21 and returned to the compressor. The oil absorbs heat of compression in the working chamber to secure greater efficiency. A shaft 24 is coupled to a rotor 29 and may be driven by the motor 21. Oil from the pipe 18 enters a bore 36 in a pin 35 and passes through ducts 37 to the chamber 38 in the rotor bore. The pin 35 is slightly smaller than the rotor bore 30 and allows oil to flow over walls 39 into a chamber 41 where its pressure is less than that in the chamber 38. The oil flows from the chamber 41 through a radial hole 42, a pipe 46 containing a restriction 46a, to a hole 49 which communicates by way of ducts 50, with the working chamber 26 and minimises work lost due to liberation of dissolved air from the oil, due to the pressure drop, the ducts 50 leading to a part of the working chamber that is under pressure.

Abstract: 733,483. Gas turbine plant. PARSONS & CO., Ltd., C. A. April 24, 1952, No. 10340/52. Class 110 (3). [Also in Group XIII] In a gas turbine plant having a regenerative heat exchanger of the kind in which a fluid agent is used to convey heat from a hot gas side situated at the turbine exhaust to a cold gas. side located at the compressor outlet, the working medium flows in both sides of the heat exchanger in a direction contrary to that of the fluid agent and the hot and cold sides of the heat exchanger each consist of a drum rotating about the turbine axis in which the fluid agent is caused to flow through the working medium by centrifugal force. A regenerative heat exchanger is defined as one in which a fluid agent alternately mixes with the hot gases and cold gases, the fluid being collected at each side alternatively and circulated by a pump. In the arrangement shown, compressed air from the compressor a enters the cold gas side c of the heat-exchanger d where it is heated before entering the combustion chamber e. After expansion in the turbine b which drives the compressor, the gases enter the hot gas side f of the heat-exchanger d. The heat exchanger d consists of two rotating drums g, h, each consisting of outer and inner walls i, j and two disc shaped end walls k, l. The working medium enters through ports m and leaves through ports n. The fluid agent enters through ports o and leaves by ports q. Radial disc-shaped ribs p ensure close contact between the fluid droplets and the working medium. Radial ribs r assist the movement of the droplets and can be shaped so as to act as turbine to rotate the drums g, h as described in Specification 733,476. The drums g, h may be driven by direct or indirect mechanical coupling from the turbine. The cooled fluid agent passes through a filter a, cooler t and pump n before passing to the hot side of the heat-exchanger. The application of the invention to gas turbine plants in which the combustion chamber is arranged on the exhaust side of the turbine and in which the plant works on a closed cycle is described. In the latter arrangement, the heat may be supplied by an atomic pile. Specification 578,686 also is referred to.

Abstract: 575,631. Hoppers. AVERY, Ltd., W. & T., and PAGE, A. E. June 2, 1944, No. 10581. [Class 78 (i)] In automatic weighing apparatus of the kind in which the material is fed from the bulk supply hopper to the scale pan &c. by a vibratory shoot a, the supply is reduced to a dribble feed by the movement of a slotted cut-off gate c from the position shown in full lines to that shown in broken lines. The gate c is disposed below the end of the shoot and is suspended from a support e by links d. One pair of these links is connected by a crossbar d<1> provided with a lug d<2> which is pivoted at h<1> to the piston rod h of a pneumatic cylinder f. The shoot a is vibrated by the means described in Specification 556,748. When the motion of the weighbeam causes the actuation of a valve through which air is admitted through the pipe b to the cylinder f to cause the projection of the gate c, the feed is reduced to a dribble supply through the slot c<1>. When the further motion of the weighbeam cuts off the supply of air to the mechanism actuating the shoot, the supply ceases. Any material remaining in the trough at the end of the weighing operation is removed by a scraper j on the retraction of the gate. This scraper is carried by arms j<1> pivoted to brackets k.

Abstract: 932,709. Self-servo brakes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 7, 1961 [March 25, 1960], No. 10639/60. Class 103 (1). In a self-servo brake of the type wherein the movement of a primary shoe incident to frictional engagement with a drum or other braking surface is utilized to force a secondary shoe or shoes into engagement with the braking surface, means is provided whereby negative feed-back is applied to the operating force on the primary shoe. In the diagrammatic form illustrated in Fig. 1, a primary shoe A and a secondary shoe B co-operate with a braking surface X which may be a disc or drum. A force F is applied via a roller R to the shoe A which is capable of movement in the direction of movement of surface X. Roller R is carried by a lever arm E of a bell-crank, the other arm E<SP>1</SP> of which is engaged by the shoe B which is also capable of movement in the direction of movement of surface X. Frictional drag of shoe A is transmitted by a lever C and link D to the shoe B to apply shoe B with a greater force than shoe A, while the drag of shoe B gives a reduced feed-back force acting on the roller R in the opposite direction to force F via the lever arms E, E<SP>1</SP>. As applied to a drum brake, Fig. 3, the bell-crank comprising arms E, E<SP>1</SP> is pivoted on a bearing E<SP>2</SP> and acted on by a force in the direction of arrow F by an hydraulic cylinder (not shown). Lever arm E carries roller R engaging floating shoe A which has a roller A<SP>1</SP> at its trailing end engaging a lever H journalled on the axis of the brake. A cam H<SP>2</SP> rotates with the lever H and operates a lever J pivoted at J<SP>1</SP> and connected by a link J<SP>3</SP> to the floating shoe B. The opposite end of shoe B carries a roller B<SP>1</SP> acting on the arm E<SP>1</SP>. The Specification includes formulµ to show that the brake can be made to give a gain of five over a simple brake and yet be two and a half times less sensitive to changes of the coefficient of friction during braking than the simple brake, while the movement of the applying force for a given degree of braking is about one-third of that of the simple brake, allowing more mechanical advantage to be employed in the transmission from the brake pedal.
