Title: Process for producing saturated petroleum products from unsaturated compounds
IPC: C10G45/00
Filed: 1920-08-12
Abstract: 174,106. Stephens, A. J., (Canadian-American Finance & Trading Co., Ltd.). Aug. 12, 1920. Mineral and tar oils.-Saturated hydrocarbon mixtures similar to commercial petroleum products are produced by vaporizing the volatile matter of an unsaturated hydrocarbon mixture and condensing to a liquid in the presence of hydrogen under pressure, say 4 to 5 atmospheres. A catalytic material such as nickel may be provided at the place where condensation occurs, but the ordinary metallic condenser walls may in some cases have sufficient catalytic action. The raw material, such as a petroleum waste or byproduct, or the product of low temperature distillation of coal, may be contained in a still 1 heated by fuel or internally by steam or inert gases. Within or outside the still the hydrocarbon vapour is mixed with hydrogen obtained from a catalytic dehydrogenator 3 supplied with natural gas or still gases. A pump 8 forces the mixture under the required pressure to a condenser 10, any uncondensed gas being returned to the dehydrogenator 3. Specifications 166,989 and 170,140 are referred to.

Title: Improvements in spray guns
IPC: B05B1/30
Filed: 1933-08-26
Abstract: 424,777. Spray - producers ; valves. DE VILBISS CO., Toledo, Ohio, U.S.A. Aug. 26, 1933, No. 23787. Convention date, Sept. 6, 1932. [Classes 69 (iii) and 135] The closing pressure on the handoperated materialcontrol valve of a spray-gun is partially counteracted by pneumatic means when the valve is open. In the form shown the nozzle member B has a shank which is caused by a tubular screw 6 to seat firmly within a bore in a boss 2 depending from the body part A of the gun. The stem 8 of the material control valve 7 terminates in an enlarged portion 12, which is engaged by a dog 11 pivoted to the trigger 9. A detachable unit C for providing the closing pressure for the valve 7 comprises a cylinder 19 containing a piston 24 with a hollow stem 22, which is pressed against the valve stem 8 by a spring 31. A second stem 35 extending through the hollow stem 22 and piston 24 is pressed against the valve stem 8 by a second spring 37, which is considerably weaker than the spring 31. When the trigger 9 is operated the valve 45 is first opened and compressed air from the conduit 40 is admitted through apertures 20 into the cylinder 19, where its pressure on the piston 24 counteracts the pressure of the spring 31, and from thence it passes via hollow screw 6 to the air nozzle. Immediately thereafter the trigger 9 withdraws the valve 7 against the closing pressure of the spring 37 only. In a modification the closing pressure is provided by one spring and the air pressure is used to relieve only a portion of the tension of the spring.

The material is rolled into a plate and hardened. The total thickness d is only slightly greater than the thickness e of the wire netting a, b. The process of manufacture consists in rolling out a thin backing of the plastic composition in a rolling machine, introducing the wire netting with a further addition of the composition, and subjecting the whole to further rolling so that the composition is pressed through the netting and rolled out into a thin top layer. The plate may be hardened wholly or in part in a press with or without the aid of heat. Strips of the material may be inserted between the leaves of a leaf spring, or annular discs thereof may be placed between the faces of a slip coupling.

A disc shaft-rotation encoder comprises two sets of tracks 2, 3 offset by one bit position the choice of reading tracks being determined by a trigger controlled by brushes on two tracks 6, 7 at the periphery of the disc, comprising alternate conducting and insulating bits each offset by half a bit position from the tracks 2, 3. At each setting of the track-selecting trigger, output triggers are reset ready for operation by the reading brushes, and then latch until the next setting. A further similarly coded disc may be geared to the first disc to provide further readings, track selection being controlled by the highest digit on the first disc. Instead of offset tracks read by co-linear brushes, a single set of digitizing tracks may be provided read by lead-lag brushes offset by one bit position of the single control scale. The output trigger circuits may be connected as a shift register to provide a serial output. The arrangement is said to provide a noise free encoder. Instead of a coded disc, a coded drum may be used.
