Title: Improvements in or relating to methods of obtaining acetaldehyde
IPC: C07C47/06
Filed: 1952-06-20
Abstract: Acetaldehyde is obtained from acetaldehyde-containing vapours produced, such as by the catalytic oxidation or dehydrogenation of alcohol by a method comprising washing said vapours with a mixture of alcohol and water, the mixture having a water content that when in contact with the vapours the resultant mixture of acetaldehyde, alcohol and water contains not more than 60 per cent of water by weight.  The vapours from which the acetaldehyde is extracted may also be obtained by a combined oxidation-dehydration process.  In an example vapours obtained by the catalytic oxidation of alcohol and containing acetaldehyde and unreacted alcohol are scrubbed in counter-current by 50-60 per cent aqueous alcohol.

Title: Improvements in or connected with speed indicators
IPC: G01P3/28
Filed: 1943-09-25
Abstract: 575,993. Speedometers. HASTINGS, G. W. Sept. 25, 1943, No. 15775. [Class 106 (iii)] A device for indicating the speed of mechanism from which a rotary drive can be obtained comprises a liquid pump whose speed of operation is dependent on the speed of the mechanism, and a piston or equivalent member movable in a cylinder under the action of liquid pumped into the cylinder by the pump. As shown in Figs. 3 and 5, the device comprises a casing A which is filled with oil and a pump B, driven from an outside shaft 4, which draws oil from the casing A and discharges it into a cylinder C also filled with oil and so causes a ball D which acts as a piston to rise and open a port 10 so that the oil escapes back into the casing A. As the speed of the pump fluctuates, the ball D moves up or down proportionately in the cylinder C, the position of the ball D at any time giving an indication of the speed of the pump and so of the mechanism driving the pump. By means of a threaded rod E which rests on the ball D, through the medium of a concave slipper 12 and gear-wheels 13, the movement of the ball D is transferred to a pointer 15 which moves over a scale of revs. per minute. The pump drive is rectified by the clutch 5, 25 if necessary. A tell-tale dial and pointer and a revolution counter are also provided.

Title: Improvements in or relating to the regulation of brakes
IPC: B60T13/24
Filed: 1930-05-22
Abstract: 357,520. Fluid-pressure brakes. MONGE, C. DE, 123, Boulevard de la Sauveniere, Liege, Belgium. May 22, 1930, No. 15812. Convention date, March 1. [Class 103 (i).] In a control device for brakes operated by the suction in the induction pipe of an internal-combustion engine, a chamber that is connected to the suction pipe under valve control and to the brake cylinder is connected also to the atmosphere through a passage which is of constant crosssection during the graduation of the braking action. This passage may however be closed when a quick application of the brakes is desired and it may be increased to effect a quick release of the brakes. As shown in Fig. 4, the casing of the control device is connected to the atmosphere, the suction pipe and the brake cylinder by the pipes 2d, 2c, 4 respectively. The valve rod 7a slidable in the casing carries a valve 6 which normally closes the suction pipe 2c and in this position a wide passage is open for the connection of the brake cylinder with the atmosphere. When the valve rod is moved to the right and the valve 6 is opened a collar 5d enters the air passage 3d, which is thus restricted and maintained of constant cross-section during the opening movement of the valve. The valve is of parabolic section so that the cross-section of the passage which it opens increases at first slowly and then quickly whereby the degree of vacuum obtained in the brake cylinder is substantially proportional to the movement of the valve rod and also to the compression of the returning spring 5m. This device may as shown in Fig. 5 be interposed between the brake pedal 15 and the lever 11 connected to the brake piston 3m and to the brake operating shaft 11b, the casing 8a of the device being connected to the pedal and the valve rod 7a to the lever. The release spring 11a is sufficiently strong to bold the valve rod normally in position against the action of the spring 5m with the collar 5d within the passage 3d. The pressure applied to the pedal in applying the brakes is transmitted through the spring 5m direct to the brakes and after the valve 6 has been fully opened the part 7b seats on the part 8 to close the air passage and also provides positive engagement between the pedal and the brake lever 11. If the pedal is released the spring 5m is able at first to move the collar 5d outside the passage 3d so that a quick release of the brake is obtained. In another construction the air passage is provided by an annular plug through which the valve rod passes and which is provided with baffles or deflectors which have a restricting effect when the intensity of the air flow increases. A slide valve is provided in this case, the suction port controlled by it being so shaped as to give a rapidly increasing opening.

Filed: 1944-08-23
Abstract: 584,753. Welding electrode holders. MIDDLETON, A. Aug. 23, 1944, No. 16055. [Class 39 (iii)] Rotation of an insulating cap a and integral metal tube e relative to an insulating handle portion b causes a plunger f to advance or retract relative to the handle and grip or release an electrode c inserted through an aperture in the cap and tube. An adapter d has a socket d<2> threaded externally and internally in opposite senses, and is fixed in the tube b by an insulating dowel pin g. The coaction of the projecting end of a pin h with a slot f<1> in the plunger prevents relative rotation between the plunger f, the tube e and cap a, but allows axial movement of the plunger. The holder may be modified slightly to take an inclined electrode. In a modification described in the Provisional Specification the plunger is drilled to take the electrode so that it may be gripped by rotation of the cap in either direction. Also, the tube is slotted instead of the plunger, the latter being fitted with a dowel pin which slides in the slot.
