Title: Improvements in brake systems
IPC: B60T13/14
Filed: 1970-02-26
Abstract: 1,249,842. Master cylinders. ALFRED TEVES G.m.b.H. 26 Feb., 1970 [1 March, 1969], No. 9360/70. Heading F2F. A brake system includes a master cylinder having a stepped piston 1 with an axial bore, a pressure medium reservoir 17, a slide 2, a valve 3, and a pressure medium accumulator, the slide and the valve being arranged in the bore and the valve being co-operable with a valve seat 5 formed in the piston bore and urged on to the seat by a spring 4 when the brake system is unactuated. Upon actuation of the system the slide is moved to abut and displace the valve from the seat against the force of the spring to thereby disconnect an annular chamber 14, formed between the outer surface of the piston and inner wall of the cylinder, from the reservoir and connect the chamber to the accumulator, subsequent movement of the piston in the brake application direction allowing the accumulator pressure to be applied to the annular surface 16 of the piston so as to boost the brake application force. As shown, upon braking action, the slide moves to close the gap 11 between the slide and valve 3 to unseat the valve so that pressure medium flows from the accumulator via. hose connection 7 to a channel 6 in the piston, a chamber 8 and past the valve seat 5 to bores 12, 12<SP>1</SP>, port 13 and to chamber 14, further movement causing disengagement of the piston abutment 21 and cylinder abutment 22 to expose the surface 16 to the pressure medium. In the initial position of the piston 1 and slide 2 the reservoir 17, chamber 18 and chamber 14 are interconnected by bore 19, gap 11 and bore 12. In a modification, Fig. 2 (not shown), the accumulator is connected to a further annular chamber (26) between the piston and cylinder via a connection (24) and a bore (25) in the cylinder housing (23) and with a cross-bore (27) extending from the chamber to the channel 6.

Patent GB-454260-A (GB)
Title: Process for the manufacture of sterol compounds
IPC: C07J75/00
Filed: 1935-03-27
Abstract: Sterol derivatives containing a conjugated double bond in one nucleus of the ring system are prepared by converting alpha-beta-unsaturated ring ketones of the sterol series into the corresponding hydroxy compounds by reduction followed by the removal of water, or if the hydroxy group has been previously esterified, by the removal of acid. Instead of the keto-sterols themselves, there may be used their acyl derivatives.  The new double bond is in conjugated position to the double bond which was originally present, and in the same nucleus. The keto derivatives of the sterols are obtained by oxidation of esterified sterols such as by chromic acid.  The ester derivatives of the keto-sterols so obtained are preferably used directly in the reduction process.  This reduction process is carried out by the use of reducing agents which reduce the keto group but which do not reduce the double linkages.  Such agents are the alcoholates of earth metals with primary or secondary alcohols such as aluminium isopropylate and magnesium and zirconium alcoholates. The second double bond may be produced in ring B by directly splitting off water, preferably in the presence of an agent which assists this process such as oxalic acid or benzoic acid anhydride.  A better method is to esterify the hydroxy group with an organic acid such as benzoic acid and heat the ester to split off one molecule of acid thus producing the second double bond. The dehydrosterol compounds thus obtained may be transformed into antirachitically active products by ultraviolet irradiation.  In examples: (1) a glacial acetic acid solution of stigmasterol acetate is oxidized with chromic anhydride to produce 7-oxo-stigmasterol.  This is reduced in isopropyl alcohol solution with aluminium isopropylate to 7-hydroxy-stigmasterol p  which is then di-benzoylated with benzoyl chloride in pyridine. One molecule of benzoic acid is removed by heating in a vacuum to give the benzoate of 7-dehydrostigmasterol which is saponified to yield pure 7-dehydrostigmasterol; (2) 7-oxo-cholesteryl acetate is reduced as in example (1) to 7 - hydroxy - cholesterol, dibenzoylated, and then heated in a vacuum to yield 7-dehydrocholesterol benzoate which on saponification is converted into 7-dehydrocholesterol.  The dehydrocholesterol may also be obtained directly from 7-hydroxy cholesterol by heating in an atmosphere of nitrogen in the presence of oxalic acid or benzoic acid anhydride.  On irradiation in ether free from peroxide with the light of a magnesium spark the 7-dehydrocholesterol is converted into a highly active antirachitic product; (3) sitosterol acetate is converted first into 7-oxo-sitosterol then into 7-hydroxy-sitosterol, then into the dibenzoate, and finally into 7-dehydro-sitosterol as in example (1).  The final product may be purified by precipitation with digitonin.

Filed: 1945-04-17
Abstract: 593,916. Making rods and tubes. JABLONSKY, B. April 17, 1945, No. 9616. [Class 99 iii)] Rods or tubes made from fibrous laminae coated with an adhesive are made by rolling two or more fibrous laminae 1. 1<1> on the mandrel 2 between the reciprocating platen 4, actuated by a hydraulic cylinder 8, and the stationary platen 3 while the required pressure is maintained by a hydraulic press 5. If the width of the laminaecorresponds to the length of the rod or tube, it is fed in at right angles to said rod or tube. Alternatively thin strips may be wound helically so that the edges of each turn abut against each other or more than one layer may be used such that one layer covers the gaps between the turns of the preceding layer. The mandrel may have a means for gripping and starting the laminae such as a circular rod fitting in a longitudinal U-shaped slot. Rods manufactured by any of these methods have mandrels of suitable material which remain in the finished article.

Title: Improvements in or relating to remotely acting liquid pressure position-indicating devices
IPC: F15B7/00
Filed: 1938-03-29
Abstract: 505,305. Hydraulic indicating - apparatus. AUTOMOTIVE PRODUCTS CO., Ltd., CLENCH, E. C. S., and KAHL, Q. H. H. March 29, 1938, No. 9637. [Class 69 (ii)] A liquid-pressure operated device for indicating the position of a member at a distance comprises an indicator connected by a pipe-line with a remote unit having a chamber of variable volume, and means for injecting a predetermined quantity of liquid into the line when an indication is required so that any liquid that cannot enter the unit causes the indicator to be actuated. The remote unit 23 comprises a cylinder 24 with a piston 25 pressed towards one end by a spring 26 bearing at its other end against a slidable tubular member 28. The movement of the member 28 is limited by the engagement of its closed end 29 with an abutment 30 on a spindle 31 carrying an arm 32 attached to the member, the position of which is to be indicated. The indicator unit 10 comprises two cylinders 11, 13 communicating with one another by a conduit 20 and connected to the cylinder 24 by a pipe-line 22. A piston 12 is pressed upwardly in the cylinder 11 by a spring 38, of greater strength than the spring 26, enclosed in a tubular extension 37 thereof, which bears against a spring-pressed arm 41 on a spindle 42 carrying a pointer moving over a scale. In the other cylinder 13 a hollow dumbell-shaped piston 14 is actuated by a toggle-linkage 15, 16 operated by an external handle 18 to raise it to the position shown. Passages 46, 58 in the piston 14 normally connect the chambers 65, 66 of the cylinders 12, 24 and the passages 22, 20 to a reservoir 59. Projecting through the passage 46 is the hollow closed stem 52 of a mushroom valve 55 adapted to coact with a seating 47 on the piston 14. The downward movement of the valve 55 under spring action is limited by a headed pin 53 secured to an adjusting screw 62 provided with a locking nut 63. To obtain a reading, the handle 18 is operated to raise the piston 14 which, as soon as the seat 47 engages the valve 55, forces liquid through the passages 20, 22. The piston 25 is thus forced back until the part 29 abuts against the stop 30, whereupon the piston 12 is forced downwardly by the remainder of the displaced liquid to actuate the pointer. The amount of liquid displaced by the piston 14 can be adjusted by varying the initial position of the valve 55 by means of the screw 62. In the final position of the handle 18, the toggle-levers 15, 16 assume or just pass a dead-centre position so that the lever can be left in operative position and a continuous indication of the position of the member can be obtained. If in these circumstances the piston 12 reaches its lowest position and an expansion of the liquid occurs due to a temperature rise, a projection 67 on the arm 41 comes into engagement with and breaks the toggle to prevent jamming of the piston 37 against the bottom of the casing.

Title: Separation of Hydrogen from other Gases
Inventor: BUCKLAND IVOR JOHN
IPC: C01B3/50
Filed: 1966-03-04
Abstract: 1,153,636. Hydrogen gas separation. INTERNATIONAL NICKEL Ltd. 20 Feb., 1967 [4 March, 1966], No. 9652/66. Heading B1L. Hydrogen is separated from a gaseous mixture by contacting the latter with palladium powder or sponge in an absorption zone, the palladium being cyclically moved into a desorption zone having a higher temperature than the absorption zone, and then back into the absorption zone, hydrogen desorbed in the desorption zone being led to a receiver. In the apparatus of Fig. 1, the gaseous mixture from a reservoir 8 is caused to fluidise palladium powder in a fluidiser 1. An overflow pipe 5 allows palladium powder to flow by gravity through a seal 6 to a second fluidiser 2, where it is fluidised by hydrogen circulated therethrough and through the pipe 21 by a compressor 20, and an overflow pipe 7 and ejector 34 remove it from the fluidiser 2 via pipe 36 to a cyclone 37, where the palladium powder is separated from the hydrogen and returned to the fluidiser 1. The bed in the fluidiser 1 is maintained at, e.g. 100‹C, by a water jacket 41, to allow hydrogen to be absorbed by the palladium, while it is desorbed by maintaining a temperature of e.g. 200‹C in the fluidiser 2 by heaters 43. Hydrogen is bled from the pipe 21 to a receiver 32. In the apparatus of Fig. 2 palladium powder is packed in a fine honeycomb of stainless steel in a rotary disc 50, and the gas from which hydrogen is to be absorbed is passed through part of the disc by conduits 59 and 60, while heated pure hydrogen is circulated through the remainder via conduits 61, 62, and bled off from this circuit to a receiver 68.

Abstract: 691,830. Heating by circulation of liquids. PIERCE FOUNDATION, J. B. April 27, 1951 [May 31, 1950], No. 9948/51. Class 64(ii) In a heating system in which a pump 7 or 27 or other means circulates a heat-transfer liquid, which releases substances of low boiling point, through a boiler and apparatus 5 to be heated, and storage means 2 receives liquid from and returns it to the remainder of the circulating system, means 6 are provided for separating vapour from the liquid preparatory to condensing it and returning it to the system. In the system shown in Fig. 1, the vapour passes from the separator 6 to the storage tank 2, in which it is condensed by contact with liquid and by a cooling element 3. The vapour separator comprises a chamber having a liquid inlet 17 and outlet 18 which are arranged in radial or tangential directions. The vapour outlet pipe 19 may project below the top of the chamber so that sufficient vapour must collect in the top of the latter to depress the liquid below the end of the pipe before the vapour can escape. The vapour separator 6 is located adjacent to the inlet of the pump 7, where pressure is lowest. The pump and vapour separator may be in the pipe line 21. Superatmospheric pressure may be applied to the surface of the liquid in the storage tank 2. In the system shown in Fig. 4, vapour from the separator 2 is condensed in a condenser 25, and the condensate returns to the circulating system through an injector 24. A tank 29 and pumps 30, 31 enable the heat-transfer liquid to be drained from the circulating system or to have other liquids mixed with it.

Title: Improvements in and relating to microscope objective changers
IPC: G02B7/14
Filed: 1926-04-15
Abstract: 271,993. Pollard, A. F. C. April 15, 1926. Microscopes.-A microscope objective changer consists of two members, one of which is fixed to the microscope and the other to the objective. These members are positioned by six bearing surfaces co-operating with six bearing points to enable the objective to be readily removed and replaced in precisely the same position without unnecessary elastic strain of the co-operating parts of the changer, and without the action of springe or clamping screws. The disc A, Fig. 4, is adapted to be secured to the microscope tube by an adapter, and preferably carries the six 'bearing surfaces for the bearing points on the other member. The axis of the disc is at an angle of about 20‹ to the axis of the instrument, so that in removing the objective the lens is lifted away from the slide, or so that, should contact be made with the lens and the slide, the objective is raised thereby and avoids damage. Of the six bearing points on the objective member, Fig. 2, the point f bears on the lower front of the face of the disc A, the point bc on the two faces of the notch B, the points de on machined flats on the back of the disc A, and the point a on the periphery. These points are formed of set screws with rounded points, so the adjustment of the optical axis &c. of the objective may be accurately effected.
