Title: Improvements in valve gear for fluid pressure engines and the like
IPC: F01D17/14
Filed: 1919-11-15
Abstract: 158,723. Baumann, K., Guy, H. L., and Metropolitan - Vickers Electrical Co., Ltd. Nov. 15, 1919. Interconnecting two or more valve members.- Relates to valve gear in which one or more additional valves, such as overload valves are successively opened after the main valve and comprises a series of links and levers extending between two fixed pivots and connecting the additional valves with the main valve. As shown in Fig. 4, a lever 6 mounted on a fixed pivot 7 at one end is connected by an adjustable link 5 to a second lever 3 also mounted on a fixed pivot 4 at its further end. The lever 3 carries a floating lever 15 to which are attached two valve connections, the valves 13, 14 being loaded by properly adjusted springs so that the valve 14 opens completely before the valve 13 begins to open. The lever 6 is operated by means of the main valve 9 through a lost motion device 8. Figs. 8 and 9 show a modified construction. A servo motor 39 is controlled by a pilot valve 32 actuated by the governor rod 35 to open the main valve 9. When the valve is fully open the piston trunk head 47 comes in contact with the sliding cross-head 45 to which the main lever 6 is attached; any further movement will open the valve 14 and then valve 13, the springs 12 and 12a being properly adjusted. A set screw 48 limits the motion of the cross-head.

Filed: 1972-06-16
Abstract: 1368011 Pressure gauges SIEMENS A G 16 June 1972 [18 June 1971] 28414/72 Heading G1L A pressure gauge includes a deformationsensing member (not shown) embedded in a mass of degasified elastic material, including silicone rubber, sealed as a diaphragm across a chamber defined by an aperture 2 in a plate 1. Fluid supplied through ducts 13, 14 to one or opposite sides of the diaphragm causes the material, and thus the deformation-sensing member, to be deformed to an extent depending on the fluid pressure(s). The diaphragm can be cast in situ using a suitable moulding tool Fig.2 (not shown) and may be covered with a protective polyamide foil.

Abstract: 1340608 Burglar alarms W BREITNER 17 June 1971 [19 June 1970] 28474/71 Heading G4N [Also in Divisions B5 and H3-H5] Metal filaments are applied to a glass sheet by interconnecting the metal filaments to filaments of transparent insulating fusible material, applying heat to the interconnected filaments to fuse the insulating filaments to at least one sheet of transparent plastics material, and connecting the or each sheet of plastics material to the face of a sheet of glass. In Fig. 1, insulating filaments 2 of thermoplastic and metal filaments 3 are knitted together and then bonded together, e.g. by heat, at their interlinking points. The metal filaments are interconnected together at the edges to form supply conductors 4. The fabric so formed is heat bonded to a transparent plastics sheet 5 which is then secured to one face of a sheet of glass or secured between a pair of glass sheets. In Fig. 5, metal filaments 13 are tacked or sewn to transparent plastics sheet 15 by insulating transparent filaments 12 and then embedded in the plastics sheet 15 by heating. The plastics sheet is then secured to a glass sheet or sheets. The insulating filaments and plastics sheet may be made of polyvinyl butyral, polyvinyl chloride, or polyethylene. The metal filaments may have thermoplastics or glass sheaths and the insulating filaments metal cores. The metal filaments may for heaters, receiving or transmitting antennµ, electrical screening, or burglar alarm glasses.

Abstract: 187,622. Scherer, B. Oct. 22, 1921, [Convention date]. Lantern doors and door fittings.-A fastening device for removable motor-headlight fronts or covers comprises springs 5, mounted on supports 6 in slots 4 on the cylindrical part 3 of the cover and adapted to ride over the bevelled edge 8 of the lamp-body 7 and engage a circumferential groove 9 formed on the body. The extent to which the springs project towards the centre increases as the length between the supports 6 increases. To remove the cover, it is pulled by hand when the springs will take up the position shown in dotted lines in Fig. 3, coming out of the groove 9. When open, the springs serve to retain the glass 1 in position. The springs 5 may be replaced by a single spring or a rubber ring mounted around the collar 3, and projecting towards the centre through the openings 4. The Specification as open to inspection under Sect. 91 (3) (a) states also that the arrangement may be reversed and the springs mounted on the lamp-body to engage a groove formed in the cover. This subject-matter does not appear in the Specification as accepted.

Title: Production of liquid oligomers of 1, 3-dienes
Inventor: WITTENBERG DIETMAR
IPC: B01J31/14
Filed: 1961-08-09
Abstract: Oligomers of 1, 3- dienes are obtained from the monomer in the presence of a solution of a catalyst obtained from a titanium compound and an aryl aluminium compound and in the absence of activating materials.  The titanium compound may be a halide, alkoxide, or mixed alkoxidehalide, an alkyl titanium halide or a complex such as (C6H5) Al2Ti Cl8 or (C6H5) AlTi Cl5.  The aryl aluminium compound should contain at least one aryl group, the remainder being aryl, alkyl, chlorine or bromine.  The mol ratio of Ti: Al may be 1 : 1-100 and titanium concentrations as low as 0,005% but preferably 0,01-1% by weight may be used.  The solvent employed is an aliphatic or aromatic hydrocarbon or aromatic halohydrocarbon preferably used in amounts of 5-500 times that of the other components; if necessary the components are heated in the solvent up to 150 DEG C. and undissolved constituents removed. Polymerization is effected at -50 to 150 DEG C. and up to 10 atmospheres and an extra solvent, e.g. the end product, may be added in an amount 0,5-5 times that of the diene. Specified dienes are butadiene, which yields cyclododecatriene, isoprene, 2, 3-dimethylbutadiene, hexadiene -1,3, 2-propylbutadiene and cyclohexadiene -1,3.

Spindle-apparatus.- A spinning centrifuge, particularly for the manufacture of artificial silk, has a balancing element partly filled with liquid the circumferential movement of which is sufficiently retarded to reduce the oscillations of the spinning pot. The nozzle 4, Fig. 3, is movable inside the pot 3 which is provided with an outer wall 6; the annular chamber 7 thus formed contains liquid 8 which, during oscillation by the shaft, takes up a position as shown in Fig. 4 tending to bring the centre of gravity of the moving mass nearer to the geometric axis. In a modification the annular chamber 7 may be constructed separately from the pot and may be connected by arms to the shaft 2. Two channels may be employed arranged in planes at right-angles to the axis and arranged symmetrically with regard to the centre of gravity. To retard the flow of liquid the transverse section of the channels may he reduced locally as for instance by means of baffle plates. In another modification, shown in Fig. 8, the balancing element consists of four chambers 10 connected bv radial channels 11 which reach to the outer walls of the chambers. The inner ends of the channels 11 may terminate in an annular channel and the tops of the chambers 10 should communicate with each other or with the atmosphere.
