Filed: 1953-05-12
Abstract: 747,497. Folding edges of sheet material. WALLWIN (TURNING MACHINES), Ltd., and FENBY, H. R. B. May 11, 1954 [May 12, 1953], No. 13167/53. Addition to 732,051. Class 42 (1). A female die member 100 of a turning or creasing machine as claimed in Claim 1 of the parent Specification is provided with an edge blade 101 for co-operation with the hot or other plate 103 and adapted to have resilient yielding movement whereby the thickness of the material 105 being turned or creased is accommodated between the blade 101 and the male die 102 when, as shown, the male die enters the opening formed by the female die for thrusting a cut piece of material into the opening. Blade 101 is partly accommodated in an undercut recess 104 in die member 100 and bears on a depending rib 111. The blade is carried by studs 106 extending through holes 110 in die member 100 and secured to the die member by a series of blade springs 107 and screws 108, or by a single blade spring. Springs 107 permit blade 101 to yield as shown during downward movement of male die 102, thereby accommodating variations in thickness of material 105, but abut against the top of die member 100 to prevent yielding of blade 101 in the opposite direction, thus ensuring firm trapping of the material between the underside of blade 101 and plate 103.

Title: Improvements in or relating to the manufacture of wire glass
IPC: C03B13/12
Filed: 1926-05-27
Abstract: 258,520. Wade, H., (Pennsylvania Wire Glass Co.). May 27, 1926. Rolling.-A method of making corrugated wire glass consists in rolling a plain sheet of glass with wire mesh embedded therein, depositing the sheet on a table with a corrugated surface, and then pressing the sheet between the table and a corrugated die. In making the sheet, molten glass is poured into the space a between the surfaces of rolls 1, 2 and the surface of an embedding roll 3, flat wire mesh 4 being fed in at the same time. The roll 3 is provided on its surface with teeth or projections 5 which push the wire into the central layer of the sheet. A roller 6 flattens the sheet, which is delivered by a guide 16 on to the corrugated upper surface of a table. The rolling apparatus is mounted on a carriage 9 which runs on rails 10 and moves above the surface of the table. A motor 13 drives the rollers 1, 2, 5 and 6 and also moves the carriage 9 along the rails 10, the speed of movement being such that the sheet as it is produced is deposited on the corrugated surface 7. The sheet thus formed has its outer surfaces " set," but its interior is still plastic, and it is partly corrugated by gravity as it lies on the table. The corrugating is completed by a pressing-die 17. The die press comprises a wheeled truck 18 which runs on the rails 10 and is connected with the roller-carriage 9 by a spring 19 and by a hinged joint 21. The die 17 is upheld by springs 23 but is forced downwards, to press the sheet, by cams 22 driven from the roll 3 by gearing 24. When the sheet of glass is being pressed against the table, the truck 18 is at rest, but as soon as the die is raised, the springs 19 draw the truck towards the carriage 9.

Title: Improvements relating to distributor valve assemblies for compressed air braking systems for railway vehicles
IPC: B60T15/30
Filed: 1953-05-15
Abstract: 740,925. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd., and SIMMONS, A. W. May 4,1954 [May 15, 1953], No. 13637/53. Class 103 (1). In a distribution valve assembly for a compressed air railway braking system comprising a control reservoir charging valve 5 operated by a movable abutment 60 to establish and to cut off communication between the control reservoir 7 and its charging source, the abutment 60 which, as shown, is a diaphragm, is subjected on one face to control reservoir pressure acting in chamber 62, and on the other face in chamber 59 to brake pipe pressure, whilst the inshot valve 4 is open, and to a pressure which is lower than brake-pipe pressure whilst the inshot valve is closed. This last condition is brought about by arranging for the space 59 to be placed in communication through passages 66 and cavity 69 with atmospheric port 104 when the inshot value 4 is in its open lower position. This arrangement avoids the possibility of the control reservoir charging valve being opened as a result of a temporary increase in brake pipe pressure above the normal made in order to speed up release of the brakes, so that the charging valve might be opened too soon and the consequential overcharging of the control reservoir causing a false operation of the valve to its application position when the brake pipe pressure returns to normal.

Title: Hydrogenation of saccharides
Filed: 1957-04-30
Abstract: Polyhydric alcohols are produced by treating an aqueous solution of a saccharide with hydrogen in the presence of a ruthenium-containing catalyst.  The catalyst may be, for example, ruthenium metal; its sesquioxide, dioxide or tetroxide; salts of ruthenium such as sodium or barium perruthenite, magnesium, strontium, calcium, silver, barium, potassium or sodium ruthenate; sodium or potassium perruthenate; ruthenium dichloride, trichloride, tetrachloride or pentafluoride; ruthenium disulphide; or potassium chloro-perruthenate.  The preferred temperature range is from 50 DEG to 400 DEG  C. and the preferred pressure range is from 100 to 1500 p.s.i.g.  The catalyst metal may be used in conjunction with a support such as carbon, alumina, silica, kieselguhr, synthetic gel or diatomaceous earth.  Another metal of the platinum group, e.g. platinum or palladium, or its oxide, may also be present.  The process may be carried out batchwise or continuously. Monosaccharides and polysaccharides may be treated according to the process of the invention.  In the examples: (a) dextrose is hydrogenated using a catalyst consisting of ruthenium metal on carbon to give sorbitol; (b) dextrose is hydrogenated using (a) a ruthenium on alumina catalyst and (b) a catalyst consisting of ruthenium and platinum or carbon or alumina supports; (c) sucrose, levulose, maltose and lactose are hydrogenated in the presence of a ruthenium on carbon or a combination of ruthenium and palladium on carbon; sucrose and lactose are hydrolysed and hydrogenated to give the corresponding hexitols, maltose gives maltitol and levulose is hydrogenated directly to the corresponding hexitol; and (d) dextrose is hydrogenated in the presence of ruthenium oxide.
