Title: Improvements in or relating to magnetic couplings
IPC: H02K49/12
Filed: 1963-04-16
Abstract: 1,042,614. Clocks. HELIOWATT WERKE ELEKTRIZITATS G.m.b.H. April 16, 1963 [April 16, 1962], No. 14966/63. Heading G3T. [Also in Division H2] A synchronous motor is used both to wind spring 23 and apply a synchronizing movement through a magnetic coupling to the fourth wheel 27 of a clock movement controlled by escapement 24. The spring 23 is wound by motor 25 through a limit clutch 26 which prevents overwinding. The motor also drives wheel 27 through members 29 of coupling 28 (see Division H2) and thus synchronizes the movement of the escapement 24. If the torque.applied is sufficient to lock up the escapement the coupling will slip a pole and apply a reverse torque to wheel 27 and thus free the escapement. In the event of a power failure coupling 28 will be deenergized and the clock will continue to be driven by spring 23.
Patent GB-666180-A (GB)
Title: An improved control system for a liquid fuel vaporizer
IPC: F23D11/46
Filed: 1949-06-03
Abstract: 666,180. Fluid-actuated valves. DEHN, S. G. (Gasair Corporation). June 3, 1949, No. 14972/49. Class 135 [Also in Group XI] A control system for a liquid fuel vaporizing apparatus comprises a first control means such as a diaphragm 48 responsive to the vapour pressure at the outlet from the vaporizer A and operative to hold open a valve C through which liquid fuel is supplied to the vaporizer A, a second control means such as a diaphragm 49 responsive to the vapour pressure at the outlet from the vaporizer for opposing the action of the first control means, and means operative in response to a predetermined condition in the vaporizer requiring liquid to be supplied thereto for interrupting the application of pressure to said second control means, thereby permitting the liquid inlet valve C to be held open by said first control means. At starting the valve C is opened by pressing a push button 67 to permit fuel to flow through pipes 83, 12 to the vaporizer A, and through pipes 83, 78 to a float chamber. The vaporizer A is preheated by means not shown and the vapour generated passes through an outlet pipe 13 to a safety valve B containing a spring pressed valve member 24, which closes on its seat on the melting of a fusible washer 26 on overheating of the vapour, and a non-return valve 20 controlling an outlet 15 to the main burner system. The chamber 23 of the valve B is connected by a pipe 61 to a space 58 in the housing of the valve C so that vapour pressure is applied above the diaphragm 48 to maintain the valve member 43 away from its seat. When sufficient liquid fuel has been supplied to the float chamber to raise the float 76 by an amount allowing a pivoted valve member 73 to open communication between a pipe 81 leading from the chamber 23 and an outlet 71 connected through a pipe 82 with a space 59 between the diaphragms 48, 49, the vapour pressure applied to the space 59 counteracts the vapour pressure in the space 58 so that the valve member 43 is closed on its seat by a spring 44. Vapour is also supplied from the outlet 71 to a burner 11 which is ignited by a pilot burner 17 and heats the vaporizer A. As the liquid evaporates in the vaporizer A the level in the float chamber falls until the valve member 73 cuts off the outlet 71 from the vapour inlet pipe 81 with the result that the liquid supply valve C is opened by the vapour pressure above the diaphragm 48 and the fuel supply to the burner 11. The liquid fuel thus continues to be supplied intermittently to the vaporizer A. The float chamber may be replaced by a thermally actuated valve adapted to connect the pipes 81, 82 when the temperature of the vapour at either the outlet 13 or the outlet 15 is below a predetermined point. An alternative construction of the valve device C is described in which only one diaphragm is employed.

Title: System for controlling the delivery volume of compressors
IPC: F04B49/20
Filed: 1974-04-05
Abstract: 1404740 Servosystem HOERBIGER VENTILWERKE AG 5 April 1974 [13 April 1973] 15139/74 Heading G3P A system for controlling the delivery of a compressor 1 adapted to be driven at varying rotational speeds by a prime mover 2, comprises a pneumatic servo-mechanism 9, controlled by a proportional regulator 12, which varies the speed of prime mover 2, the compressor being adapted to be switched to an idling condition when a lower control limit is reached, a switch 16 being adapted to be actuated by mechanism 9 both for stopping and restarting the compressor delivery. Switch 16 comprises a valve 20 connected to the compressor suction valve 3 and to the pressure vessel 7, and actuated by a cam 21 carried with lost motion by an adjustable rod 17 actuated by servo 9. In operation, compressor 1 is driven by an internal combustion engine 2 at full speed until a predetermined delivery pressure is reached, whereupon regulator 12 actuates servo 9 which displaces an injection pump 11 to thus reduce the engine, and therefore the compressor, speed. Valve 20 actuated by rod 17 and the lifter mechanism of valve 3, is operated and the delivery of the compressor is stopped. If the pressure in vessel 7 drops below a pre-set level, regulator 12 causes the servo to speed up the engine and compressor by displacing rod 17, and valve 3 is closed so that the delivery pressure again increases. The switch 16 may be replaced by a slide-valve, or by an electric switch.

Title: Improvements in the manufacture and production of ketones
IPC: C07C49/04
Filed: 1928-05-15
Abstract: 318,124. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). May 25, 1928. Ketones; aldehydes; alcohols.-Ketones are prepared by passing aliphatic, or side chain cycloaliphatic or aromatic dihydric alcohols over catalysts containing one or more heavy metals of groups 1 and 8 of the periodic table, or mixtures or compounds thereof, with or without activating agents which are either alkaline, or are decomposed into alkaline, compounds under the conditions of working, and, if desired, difficultly reducible metal oxides. The primary catalyst preferably contains copper. The activating agents which may be employed therewith include oxides, hydroxides, carbonates, formates, acetates, oxalates, phosphates, and silicates of the alkali or alkaline earth metals. As examples of difficultly reducible metal oxides those of thorium, tungsten, chromium, manganese, aluminium, silicon, titanium, cereium, and magnesium are specified; mixtures of these oxides may be used. The catalyst may be deposited on carriers such as pumice, fullers' earth, diatomaceous earth, or granular aluminium, with the aid of binding agents such as water-glass, colloidal silica, or aqueous sugar solutions. The reaction is preferably carried out at temperatures between 150‹ and 300‹ C., and ordinary, reduced, or increased pressures may be employed. A non-oxidizing vapour or gas, such as steam, nitrogen, hydrogen, or mixture thereof, may be present, and, as is then preferable, the process may be made cyclic- When hydrogen is present, aldehydes formed in the reaction may be reduced. The examples describe the production of (1) methylethylketone from 1: 3-butyleneglycol, (2) methylisopropylketone from 2-methyl-1 : 3-butyleneglycol (3) methylpropylketone and acetone from 2 : 4-pentandiol (4) methylisopropylketone from trimethylethyleneglycol (5) unsymmetrical diethylacetone from alpha-methyl-##<1>-diethylethyleneglycol and (6) benzylmethylketone from phenylpropandiol. In some of the examples, small proportions of aldehydes and alcohols, including acetaldehyde, butyraldehyde, ethyl alcohol, and isopropyl alcohol, are formed in addition to ketones.

Title: Improvements in or relating to blades for gas turbines
Inventor: TUNSTALL CUTHBERT MARKLEW
IPC: B23P15/02
Filed: 1955-05-27
Abstract: 817,660. Making gas - turbine blades. BRISTOL AERO-ENGINES Ltd. May 22, 1956 [May 27, 1955], No. 15464/55. Class 83 (2). A gas-turbine blade having an aerofoil working portion 2 with longitudinal cooling passages 7-10, a platform part 1, and a root portion 3 with abutment shoulders 5, is made from a blank having at least at one end a cross-section corresponding to that of the platform part and having longitudinal passages 8, Fig. 2, extending therethrough, and the root portion of the blade is formed by cutting an open-ended slot 12 in the said one end of the blank, forging the blank to press the prongs 16, 17 thus formed into contact with one another along the line 18, and then machining the end of the blank to the desired root form, the dimensions and position of the slot 12 being such that none of the cooling passages 7-10 in the finished blade break through any of the abutments 5 in the root. The blank may be formed by extrusion with four longitudinal passages 7-10, Fig. 1, disposed on an arc. The sides 31, 32 of the slot 12 extend tangentially to the holes 8 and 7, 10 respectively. After machining the root 3, the aerofoil portion 2 is machined and, if required, a shroud may be provided at the tip of the blade. The transverse passage 19 formed by closing of the prongs may be closed at one end to provide an inlet passage for cooling fluid ; alternatively it may be closed at both ends and in this case ports such as 8a are drilled. The blank may alternatively be formed by forging in which case the blade portion may be rough forged to aerofoil shape and subsequently machined, or may be precision forged so as to require final polishing only. The root portion of a forged or extruded blank may be forged before cutting the slot 12 to flatten the arc containing the cooling passages 7-10 and thus reduce the required width of the slot. In another embodiment, Figs. 4, 5 (not shown), the slot 12 is of V-section. The root may be formed with its abutments 5 parallel with the junction plane 18 of the prongs Fig. 3, or with the abutments extending perpendicular to this plane. In the latter case the abutment may lie along large radius arcs to suit the curvature of the rotor disc into which the blades are fitted.
