Abstract: 724,956. Type-bar-making machines. MERGENTHALER LINOTYPE CO. March 4, 1953 [March 4, 1952], No. 6019/53. Class 100 (3). Assembling matrices.-A typographical line-composing machine is provided with a supplemental guide shoot forming an extension of the main shoot from the inclined conveyer belt for guiding matrices formed with upper and lower projecting pairs of ears to the assembler, the supplemental shoot having opposed guide walls for receiving the lower ears, one wall being afforded by the rim of a constantly-rotating wheel and the other by rails laterally spaced and arranged concentrically with the wheel, whereby the upper portions of the matrices swing forwardly between the rails about their lower ears during passage of these ears along the supplemental shoot, so that the matrices are caused to enter the assembler with their upper ears foremost, the guide rails being of a length to permit the upper ears to pass over the tops of the rails. The main guide shoot comprises a pair of rails 5 for engaging the matrices by their ears, a groove thus formed between the rails receiving the body portions of matrices whose ears are not in alignment with their following faces. The supplemental shoot comprises a wheel 11 and a pair of guide rails 12. The wheel 11 is constantly rotating and comprises a pair of flanges 11a to engage the lower ears of the matrices, and an annular groove 11b to accommodate the body portions of backmilled matrices. The rails 12 are pivoted at their upper ends, are arcuate, and are spring- urged into a position concentric to the wheel 11. The rails 12 also engage the lower ears of the matrices, the body portions passing between them. The supplemental shoot acts to swing the matrices forwards so that the upper ears pass over inclined upper surfaces 12b of the rails 12 and on to raised portions 15a of upper supplementary supporting rails 15 in the assembler. The lower ears then pass below the rails 12 and the matrices swing about their upper ears into the assembler.

Title: Improvements in and relating to the manufacture of sulphuric acid by the contact process
IPC: C01B17/765
Filed: 1935-02-28
Abstract: <PICT:0454327/III/1> The catalytic oxidation of sulphur dioxide is effected in four or more stages, the conditions of which are determined so that the conversion does not exceed 50 per cent in the first stage and 25 per cent in any subsequent stage, while the temperature is progressively decreased as conversion proceeds. Control is effected by proportioning the amount of catalyst and by inter-stage additions of oxygen-containing gas and heat-exchangers with the unreacted gas.  As shown in Fig. 3, a mixture of sulphur dioxide and air is moistened with water in a tower 1 and passes through heat exchangers 2--5 and then successively through reaction chambers 6--10, further quantities of air being added at the points 11--14.  The residual sulphur dioxide in the exit gas may be recovered and concentrated for recirculation as described in Specifications 378,464, <PICT:0454327/III/2> 400,998, and 430,092. The sulphur trioxide produced may be directly condensed with steam as described in Specification 406,116 or 430,092.  The temperature variation through out the conversion is shown by the dotted line in Fig. 4, in which A B C D is the area within which the temperatures attained in the successive stages should lie, while E F shows the minimum temperature at which the gas should enter each stage in the case of a platinum catalyst.  The proportion of oxygen present at any stage in the total gases (excluding water vapour) should be in linear relationship with the ratio of oxygen to (oxygen + inert gases) in the total gas added in preceding stages.  In the case where air is used throughout the value lies between 4 and 14,5 per cent. Specification 445,711 also is referred to.

Title: Installation for forcing viscous liquid into a container
IPC: F04F7/02
Filed: 1929-03-01
Abstract: 327,531. Stewart & Co., Ltd., D., and Holmes, T. E. March 1, 1929. Actuating by liquid pressure; valve gear.- Apparatus for forcing viscous liquids comprises one or more rams 1, Fig. 1, each working in a hydraulic cylinder 4 and a cylinder 2 for the viscous liquid, the latter cylinder being provided with inlet and delivery valves 10, 11, the operation of which is controlled by the pressure valve of the hydraulic cylinder. The valves 10, 11 are connected to pistons 13', 18<1> in cylinders 14, 19, one side of the pistons being always under pressure admitted through pipes 16, 20 supplied from a pipe 25, which also supplies the cylinders 6 of rams 5 for effecting the return stroke of the ram 1. Hydraulic pumps are connected by pressure and return pipes 35, 41<1> to a valve block 29 fitted with a pressure valve 30, Fig. 3, exhaust valve 31, non-return valve 32, and a valve 33, and the pipe 41<1> is also connected to a storage tank. During the return stroke of the ram 1, the valve 10 is open so that viscous liquid may enter the cylinder 2, and a lever 74 is in the position shown, so that the exhaust valve 31 is open and the valve 30 closed to allow liquid from the cylinder 4 to pass through the pipe 38, non- return valve 32, and valve 31 to the pipe 41<1>. At the end of the return stroke, a tappet 105 acts through members 102 to remove a detent 97 from engagement with a member 92; a weight 89 then actuates the lever 74 to open the valve 30 and allow the exhaust valve 31 to close. Pressure liquid then passes from the pipe 35 through the valve 30 into a chamber 40, whence it passes through the pipe 23 to close the valve 10, and through a pipe 55<1> to close a valve 51 to prevent passage of liquid through a pipe 52 to the storage tank. When the pressure in the chamber 40 reaches a predetermined valve, it acts on a shoulder 106 to open the valve 33 and obtain access to the pipe 38 leading to the cylinder 4; finally the pressure acts through the pipe 23 to open the valve 11, and the forward stroke of the ram 1 is commenced, continuing until a cam 81 returns the lever 74 into position to allow the valve 30 to close to open the exhaust valve 31, and to move the member 92 into engaging position with the detent 97.
