Patent GB-866395-A (GB)
Title: A process for the selective hydrogenation of unsaturated compounds present in c -fractions
IPC: C07C7/163
Filed: 1960-01-06
Abstract: The selective hydrogenation of acetylenes, or acetylenes and butadiene, in a C4 hydrocarbon mixture is effected by conducting the hydrocarbon, as a liquid in the trickle phase in a hydrogen atmosphere, over a hydrogenation catalyst under conditions such that only acetylenes and/or butadiene are hydrogenated without forming substantial amounts of butane.  The process is useful for purifying butadiene by removing acetylenes, or for purifying butenes by removing butadiene and acetylenes. Suitable conditions are 0-50 DEG C., sufficient pressure to maintain the liquid phase, e.g. 5-20 atm., lower pressures being used when hydrogenating acetylenes alone, and space velocities of 3-40 kg. of hydrocarbon per litre of reaction space.  The catalyst, which is preferably in a fixed bed, may be platinum or palladium in an amount of 0,2-5% on a support, or 2-15% nickel or cobalt on a support, suitable supports being clays, pumice, weakly sintered alumina or magnesia, alumina gel, silica gel, active carbon or natural aluminium or magnesium silicates.  The support is preferably macro-porous, with a surface area of less than 50 square metres/gm. and a water absorption capacity of at least 10%.

The intake and/or exhaust pipes of a piston engine or pulse type jet engine have means for varying their effective acoustical lengths to produce resonance in the pipes assisting the charging and removal of exhaust at varying engine speeds. In Fig. 1 the effective length of the intake pipe 6, opening into a plenum chamber 8, is varied by a slide 11 movable manually to open holes 9a . . . 9f in the pipe. The exhaust pipe 3 opens into a telescopic sliding sleeve 15 opening into an expansion chamber 16, the effective length of pipe 3 being varied by moving the sleeve by means of control rod 17. The resonance effects in the pipes 6, 3, may be amplified by Helmholtz resonators 7, 14, connected thereto. Alternatively or in addition, each pipe may have a pulse producing device (7a), Fig. 5 (not shown), connected thereto to increase the pulse effects in the pipes. The device (7a) comprises a diaphragm (55) operated by an electromagnet (51) energized by a switch (21) actuated by an engine-driven cam (23). In a modification Fig.6 (not shown) the slides (11), (15), are adjusted automatically by an engine driven centrifugal governor operating a master hydraulic piston actuating slave pistons attached to the slides.

Title: Improved means for varying the relative speed between a driving and a driven member
IPC: F16H15/04
Filed: 1927-01-08
Abstract: 288,372. Freeborn, J. E. Jan. 8, 1927. Variable-speed friction gearing comprises a flexible member f which makes contact on its opposite surfaces with driving and driven wheels or drums a, e, Figs. 1 and 2, and is adapted to be deflected to conform more or less to the surfaces of either wheel to vary the speed transmitted. The band passes over jockeys g which can be moved from a control wheel n. When the band f is flexed over the driving-wheel a it forms part of a driving friction element with increased radius, so that the drum e is driven at maximum speed. When the band is flexed over the driven wheel surface, the speed is minimum. Intermediate contours of the band yield intermediate graduallyvariable speeds. In a form adapted for bevelgearing shown in Fig. 6, the flexible member F is a disc which turns loosely and is flexed over either bevel gear A or E.

Abstract: 822,282. Low tension sparking plugs. REGIE NATIONALE DES USINES RENAULT. Jan. 8, 1957 [Jan. 11, 1956], No. 742/57. Class 7(4) [Also in Group XXXVI] In a method of manufacturing an electrode insert for a low tension sparking plug of the surface discharge type, the insulation between the electrodes consisting of glass, one or both electrodes is coated with a suspension of powdered glass in a liquid, the suspension having a pasty consistency, by means of a brush or by gun spraying and the coating is dried and fused. The insulator is particularly of borosilicate glass as described in Specification 822,281 referred to. The electrodes are scoured and slightly oxidized before application of the suspension by rapidly heating them to dark red heat. After the suspension liquid has evaporated off the coated parts are heated in air or nitrogen until the glass particles melt. By applying several coats of glass alternating with heating steps it is possible to form relatively thick glass layers on the metal. In Fig. 1 the electrodes 1, 2 are coated separately as set forth above. The electrodes are assembled upon completion of the vitrification whilst the hot mass of glass has a pasty consistency whereby it may flow to fill the gap between the electrodes. In Fig. 2 the electrode 4 is provided with a glass layer in the manner above described. After cooling the lower face is ground and the mica washer 6 and the other electrode 7 are assembled in position.

Title: Motor power factor controller with a reduced voltage starter
Inventor: NOLA FRANK JOSEPH
IPC: H02P1/28
Filed: 1986-07-17
Abstract: A power factor type motor controller in which the conventional power factor constant voltage command signal is replaced during a 5 to 30 second starting interval with a graduated control voltage. A ramp generator 174 provides an initial ramp-like signal which replaces a constant power factor signal supplied by potentiometer 70. The ramp-like signal is applied to terminal 40 where it is summed with an operating power factor signal from phase detectors 32, 34, and 36 to thereby obtain a control signal for ultimately controlling SCR devices 12, 14, and 16 to effect a gradual turn-on of motor 10. The SCR devices are turned on at an advancing rate with time in response to the summed or combination signal rather than simply as a function of a ramp-like signal alone, to thereby eliminate motor instabilities.
