Title: Production of acetaldehyde
IPC: C07C45/30
Filed: 1965-04-06
Abstract: Acetaldehyde is obtained by contacting ethylene with an aqueous oxidizing composition at a pH of from 0.5 to 3.5 containing cupric chloride and a catalytically active palladium compound which, in the aqueous composition, forms with the ethylene a complex that hydrolyses to yield acetaldehyde and simultaneously or subsequently contacting the composition with oxygen, the value of the E.M.F. of the composition being maintained at from 260 to 400 millivolts as measured between a platinum electrode and a saturated calomel electrode at 80 DEG  C. by controlling the ratio of the amounts of ethylene and oxygen, contacted with the composition. The palladium compound may be chloropalladous acid or a salt thereof or a mixture of such metal salts, an organic carboxylic acid salt of palladium or palladium chloride and the aqueous oxidizing composition is suitably from 0.005 to 0.03 molar with respect to the palladium in the palladium compound.  The composition may also contain cuprous chloride, preferably in an amount of 0.5 to 5 moles of cuprous chloride per mole of cupric chloride. The ethylene feed may be that resulting from the pyrolysis of a low-boiling hydrocarbon, e.g. propane or natural gas, and the process may be effected at a temperature of 0-250 DEG  C., and a pressure of 1-50 atmospheres. Suitable flow diagrams are described and in a two-step process the aqueous oxidizing composition may be regenerated by contacting with oxygen, e.g. air, under the above conditions of temperature and pressure.

Title: Improvements in steam draining devices
IPC: F16T1/14
Filed: 1938-05-17
Abstract: 493,691. Steam - traps. SKERRETT, W. S. (Aktiebolaget Rosenblads Patenter May 17, 1938, No. 14702. [Class 64 (ii)] In a steam-trap comprising a condensate chamber 1 separated by a partition 10 from a pressure channel 12, both of which communicate with the inlet through a throttled opening 13 and the common inlet pipe 3 respectively, and having a discharge pipe 6 with apertures 7, the latter are normally kept closed by a slide 8 integral with a piston 9 by the equilibrium of the down-thrust of the liquid in the channel 12 on the underside of the piston and the pressure of the condensate already in the chamber 1 on the upperside of the piston, excess liquid entering the chamber 1 from the channel 12 overcoming this equilibrium and moving the piston downwards to uncover the apertures and discharge this excess. The piston thus oscillates over a short range and may be at the base of a long slide or nearer the apertures, as shown by the dotted lines. A guiding funnel 15 may be attached to the slide to direct the excess condensate directly to the apertures and prevent extraneous pressure differences influencing the piston. In a modification of the invention, the inlet and outlet openings 3, 5, Fig. 2, are arranged in an upper casing 2 above the draining and control means in a lower casing 4a. The piston is replaced by a bellshaped member 9a surrounding a pressure chamber 1a which communicates with the inlet opening by a throttled communicating pipe 13a. A seal of mercury is arranged between the wall of the condensate chamber and the pressure chamber 1a into which the lower part of the piston 9a depends. The apertures 7 may be obliquely directed in the wall of the discharge tube or arranged tangentially to the tube axis.

Abstract: 705,140. Check valves. ELECTROL, Inc. June 11, 1952 [June 12, 1951], No. 14760/52. Class 135 A check valve which may also be operated manually or mechanically from outside the valve casing 11 comprises a valve member 30 spring- loaded towards a valve seat 31 and having a valve stem 53 passing through the valve seat and slidably engaging a piston 45 itself slidable in the valve casing, the piston having substantially the same effective area as the valve member and being urged by fluid pressure against the valve stem to unseat the valve member with a force substantially the same as that exerted by fluid pressure on the valve member in a direction to close it so that the piston is easily movable to unseat the valve member by means of a plunger 35 operable from outside the valve casing 11. The casing 11 has inlet and outlet bores 15, 16 connected respectively by angledrilled passages 17, 18 to a bore 19 formed with a seat 21 for a flanged sleeve 20 in which the piston 45 slides. The sleeve 20 has one or more ports 29. The flanges 23, 24 of the sleeve 20 are grooved to receive rubbery rings 25, 26 in sealing engagement with the bore 19.

Sheet-registering devices and carriers.-Sheets are fed to ruling and like machines by a belt as 8 passing over adjustably mounted rollers 10, 11, 12, and fitted with cords 9 to prevent slipping of the sheets, which are registered by rising and falling pointed gauge fingers 38 carried by a shaft 28 which is mounted and actuated in such a way as to permit of adjustment of the time of operation of the gauges, and of their position. The axis of the cam which operates the gauges is at right angles to the pivotal axis of the gauges. The shaft 28 is fitted with end socketed portions which revolve on studs 30 fitted with balls 31, Fig. 6, forming part of a ball-and-socket joint connecting the studs to uprights 25 which are lcngitudinally adjustable in guides 17 fitted to the side frames 7 of the machine. Both ends of the shaft 28 are similarly mounted and by fixing one end and adjusting the other, the gauges may be made to correspond with the transverse cut of the paper to be ruled. The gauges 38 are adjustably held by screws 39 in sockets on sleeves 33, and the sleeves 33 are adjustable longitudinally of the shaft 28 and are held in place by screws 34 engaging a recess in the shaft 28. The shaft 28 is oscillated from a face cam 41, Fig. 3, the shaft 40 of which is parallel to the frames 7, and at right angles to the shaft 28. The cam 41 acts on a roller 44 carried by a bell-crank lever 42 the pivot 56 of which is adjustable axially by a screw 57 so as to vary the time of action of the gauges. The bell-crank 42 is fitted with a bearing plate 46 which acts on an adjustable screw 50 carried by an arm 49 on a sleeve 48 fixed to the shaft 28. The cam 41 acts to move the gauges 38 away from the belt through the agency of the lever 43, plate 46 and arm 49, and they are returned by an adjustable spring 53 acting on a second arm 52 on the shaft 28.

[Class 7 (ii)] In an engine comprising tandem cylinders 1, 2, in which are pistons 3, 4 connected in tandem, the connection between the pistons comprises a trunk 5 through which fuelcharges are admitted to the cylinder 2 and are later transferred to the cylinder 3, the admission and transfer being controlled by a valve operating in the trunk. The trunk is open to an induction space 11 and is provided with ports 13, and the valve is in the form of a piston 14 operated from the crankshaft. During the outward stroke of the piston, the valve uncovers the ports 13 so that a .charge is induced into the cylinder 2, this charge being compressed during the return stroke near the end of which a recess 15 in the piston 14 connects the cylinders so that the charge is transferred to the cylinder 1. The piston 3 compresses the charge during the next outward stroke, and the charge is then fired in the usual way ; supercharging may be effected by making the charging cylinder 2 of greater capacity than the power cylinder 3. The Figure shows two sets of cylinders supplied from, the same induction space 11; where only one set is supplied, a non-return valve is.fitted between the induction chamber 1 and the carburetter to prevent back pressure passing to the latter.
