Patent GB-1533023-A (GB)
Title: Rotary valve
IPC: F16K5/20
Filed: 1976-03-19
Abstract: 1533023 Valves EISENBAHN VERKEHSMITTEL AG 19 March 1976 [21 March 1975] 11265/76 Heading F2V A rotary ball valve, e.g. for discharge pipes on railway tank wagons, comprises a partspherical or spherical obturator 12, Figs. 1 and 2, co-operable in its closed position with packing 22 carried by a spring-biased sleeve 21. Moreover, the obturator is mounted on an eccentric portion of an actuating shaft 4 and is rotatably connected thereto by lost-motion means. The latter comprise a pin 15 co-operating with a groove 16 and a ball and notch coupling 19, 17. After removal of latching pin 11 the handle 7 is rotated through about 180 degrees from the valve-closed position shown. The shaft 4 initially rotates freely within the obturator over about 90 degrees until pin 15 abuts the other end of the groove 16 and ball 19 engages notch 17. During this portion of shaft rotation the obturator does not rotate but, due to the eccentricity of the shaft, moves along an arcuate path away from the packing 22, Fig. 4 (not shown). Rotation of the shaft over the remaining 90 degrees rotates the obturator to its open position, Fig. 3 (not shown), wherein a stop pin 13 on the obturator abuts second stop surface 14 and a stop boss 8 on the handle abuts the alternative stop surface 10. Subsequent movement of the handle in the opposite direction rotates the obturator via coupling 17, 19 until pin 13 once again abuts the first stop surface 14, whereafter further rotation of the shaft disconnects the coupling 17, 19 and the shaft rotates freely within the obturator to return it along the arcuate path into sealing contact with the packing 22. The peripheral wall of the sleeve 21 is rounded as shown to enable the sleeve to automatically take up the best sealing position with the obturator.

Title: Improvements in the manufacture and production of valuable hydrocarbons by destructive hydrogenation
IPC: C10G1/06
Filed: 1930-04-09
Abstract: <PICT:0358926/III/1> Finely divided carbonaceous materials are destructively hydrogenated by causing them to fall freely in the presence of hydrogen or hydrogenating gases through a pressuretight vessel containing heating members, such as hollow plates, pipes and the like, or electrical resistances.  Catalysts immune to sulphur poisoning, in finely divided solid, liquid, or gaseous form may be used.  The fall of the materials may be interrupted by heated deflecting members, which may be agitated, and may be coated with catalyst.  Finely ground gas coal is dropped through a valve K, into a vessel B which contains a perforated inner lining D bearing electrically heated sieves C, and reciprocated by an eccentric E. Hydrogen is introduced by a pipe J.  Annular plates M enable the volatile products to be collected from three separate sections. In another form, brown coal tar is sprayed over tubes through which flow hot combustion gases.
Patent GB-381497-A (GB)
Title: Improvements in and relating to brake adjusting means
IPC: F16D65/52
Filed: 1932-04-20
Abstract: 381,497. Adjusting brakes. TRACHSEL, E., 59, R÷ntgenstrasse, Z³rich, and HœSSY, W., Aarburg, both in Switzerland. April 20, 1932, No. 11306. Convention date, May 18, 1931. [Class 103 (i).] Automatic slack adjusting device for brakes comprises a spring disposed in the transmission so as to transmit the braking force but sufficiently stressed as not to yield under such force and a clamping device which holds the spring stressed but which is loosened during the application after a predetermined application movement of the transmission members to permit expansion of the spring and the consequent take-up of the excess of slack. The initially stressed spring 5 abuts on the end 6a of a cylinder 6 connected by rod 17 to the brakes and at its other end abuts by plate 4 on the rod 3 which is connected to the pedal lever 1. The rod 3 carries a nut 21 which passes freely through the end of the cylinder 6. Expansion of the spring is prevented for the reason that the end part 3a of the rod 3 is tapered in plan view and engages, through a plate 9, the end of a pin 8 screwing into a tubular shaft 7 traversed by the rod and extending across and carried by the cylinder 6. A pin 11a on an arm 10 secured to the pin 8 is disposed in a slot in a rod 12 attached to fixed member 15. If when the brake is applied there is an excess of clearance between the brake shoes and the brake drum, the pin 11a moves to the end of the slot so that the arm 10 is turned, lossening the grip of the pin 8 on the rod 3a, thus enabling the spring 5 to move the cylinder 6 and rod 17 towards the pedal so that the excess of clearance is taken up. Such adjustment can be effected until the end 6a of the cylinder reaches the enlarged end of the nut 21. The cylinder can be returned to its original relative position and the spring compressed to its original degree by screwing the nut along the rod 3.

Title: Improvements in and relating to organic titanium compounds
Inventor: FELD RAOUL
IPC: D06M13/503
Filed: 1960-03-31
Abstract: Polymeric hexylene glycol titanates and/or dehydration products thereof have titanium contents of 16-18.4% and are formed by reacting 2 mols of a tetra-alkyl titanate having 2-8 carbon atoms per alkyl group with 4 mols of 2-methyl-n-pentane-2, 4-diol and 1 mol of water, and, if a product with more than 16% of titanium is required, partially dehydrating the products.  The products are usually solids, free from terminal alkyl groups and useful for imparting water-repellent properties to fabrics. For this purpose they may be used in an organic solvent, e.g. benzene, tri- or per-chlor-ethylene, together with a wax, e.g. paraffin or micro-crystalline wax.  In Examples (1), (2) tetra-isopropyl titanate, 2-methyl pentane-2, 4-diol and water was reacted to give a solid product which was filtered off and dried over calcium chloride. (3) Tetra-sec.-butyl titanate was used as starting material. (4) Tetra-n-propyl titanate was used.ALSO:Water-repellent properties are imparted to fabrics by impregnating them with polymeric hexylene glycol titanates in an organic solvent, removing excess solution and drying in air preferably at slightly raised temperature, e.g. 40-50 DEG C.  Wax, e.g. paraffin or micro-crystalline may be included in the solution if desired.  In Example 5 fabrics are impregnated with trichlorethylene or white spirit concentrates prepared by dissolving molten paraffin wax in perchloroethylene and adding a polymeric titanate according to the invention.  The water repellent properties of the treated fabric was measured and compared with controls.

Filed: 1964-03-18
Abstract: 1,083,321. Multistable circuits. SOLARTRON ELECTRONIC GROUP Ltd. March 11, 1965 [March 18, 1964], No. 11510/64. Heading H3T. [Also in Division G4] A tristable circuit (Fig. 3) comprises an Eccles- Jordan bi-stable circuit with a third transistor VT3 of opposite conductivity type in the common emitter lead. One stable state is with all three transistors non-conducting, and a negative pulse at 24 will then turn on VT3 and one of the others, depending on the application of suitable voltages to their bases (not shown). VT1 and VT2 can be switched on and off in the usual way, while a positive pulse at 24 cuts off all three transistors. The resistor 18 can be transferred to or repeated in the common collector circuit (Figs. 4 and 5, not shown), the base of VT3 being joined to a potential divider across the supply; the bases of VT1 and VT2 are triggered through diodes. The circuit can be used to supply a glow-discharge numeral indicator (Fig. 6, not shown), from binary-coded decimal signals from a counter (see Division G4), a separate circuit being used for each pair of numerals in the discharge tube. The tristable circuit can also be used as one stage in a ring counter (Fig. 7, not shown), the collector of VT2 being capacitively coupled to the base of VT1 in the next stage. Transfer pulses can be applied (a) to remove the collector supply voltage of VT1 and VT2; (b) to drive the bases of VT1 and VT2 negatively through diodes; (c) to drive the common emitters negatively through diodes; (d) to drive the bases of VT3 positively through diodes; or (e) to drive the collectors of VT3 negatively through diodes. Pentastable circuit.-If VT3 is replaced by a second Eccles-Jordan bi-stable circuit (Fig. 8, not shown), with all four emitters joined together, five stable states can exist, four with each one of one bi-stable with either one of the other bi-stable conducting, and a fifth state with all transistors turned off. The circuit is switched by negative pulses applied to the bases through diodes.

Title: Improvements in or relating to fluorinated alcohols
Filed: 1951-05-17
Abstract: 1, 1-Dihydroperfluoroalkyl alcohols of formula CnF2n + 1CH2OH where n is 3-17 on reaction with acrylyl chloride in the presence of barium chloride yield acrylate esters which polymerise on heating with benzoyl peroxide.ALSO:The invention comprises 1, 1-dihydroperfluoroalkyl alcohols of formula Cn F2n + 1 CH2OH where n is 3-17.  They may be made by the catalytic hydrogenation of the corresponding alkyl esters of saturated aliphatic fluorocarbon monocarboxylic acids at elevated temperatures and pressures in the presence of a copper chromium oxide catalyst or by reduction of these acids or their acid chlorides with lithium aluminium hydride.  The alcohols may be esterified, e.g. to the acetate and with sulphuric acid yield the sulphate.  Alcohols are specified in which n is 3-12. Acetate esters of alcohols in which n is 3 and 9 are specified and an acrylate ester of the former alcohol is also specified.  In examples (1), (2), and (3) 1, 1-dihydroheptafluorobutyl alcohol is prepared respectively by reduction of the corresponding acid or its chloride with lithium aluminium hydride or by hydrogenating the acid butyrate in the presence of a copper chromium oxide catalyst containing barium in (1) heptafluorobutyraldehyde is also formed cf.  Specification 676,273, in (4) 1, 1-dihydro-n-nonadecafluorodecyl alcohol is prepared by hydrogenating n-methyl nonadecafluorocaprate in the presence of a copper chromium oxide catalyst and in (5) 1, 1-dihydro-n-nonadecafluorodecyl alcohol is made by reducing methyl n-nonadecafluorocaprate with lithium aluminium hydride. In further illustrations 1, 1-dihydro-n-hepta-fluorobutyl and 1, 1-dihydro-n-nonadecafluorodecyl alcohols are converted to the acetates by treatment with aceticanhydride and pyridine and the perfluorobutyrate of the former alcohol is obtained by treating the alcohol with heptafluorobutyryl chloride.  The acids used as starting-material may be made electrochemically from the corresponding carboxylic acid dissolved in anhydrous liquid hydrogen fluoride which solution on treatment with direct current yields the fluorocarbon acid fluoride which may be hydrolyzed to the free acid. The acid chlorides may be obtained from the acid by treatment with phosphorus pentachloride.
