Title: Improvements in or relating to the manufacture of vinyl and ethylidene esters
Filed: 1944-09-22
Abstract: Vinyl and ethylidene esters are produced by reacting acetylene with a saturated aliphatic mono-carboxylic acid in the presence of a small amount, preferably about .0001-.01 gram mol./l. of absorber liquor, of cacodyl oxide.  Excess of acetylene may be passed into the acid containing a mercury catalyst such as mercuric sulphate or acetate, and about .005-.1 gram mol./l. of methane trisulphonic acid, at 80-100 DEG  C., the vaporized ester being recovered by condensation. Esters specified are vinyl and ethylidene acetate, propionate and butyrate.  Tar formation is reduced.  In examples: (1) glacial acetic acid containing acetic anhydride, methane trisulphonic acid trihydrate (.007 gram mol./l.), and cacodyl oxide (.0013 gram mol./l.) is heated to about 85 DEG  C. while flushing with acetylene, and then held at 90-95 DEG  C. while passing acetylene, and adding at intervals a solution of mercuric acetate in acetic acid; (2) reaction is effected as in (1), but mercuric sulphate is the catalyst and is added to the initial charge.

Abstract: 1466358 Regulating and measuring viscosity ITT INDUSTRIES Inc 25 April 1974 [4 May 1973] 18124/74 Heading G1S Fuel whose viscosity is to be regulated is supplied by pipe 1 and forced by a constant volume pump 6 through capillary tubes 8 and 20, the pressure drop across the tube 8 being related to the viscosity of the fuel and measured by means 13, connected by pipes 11, 12 to the tube, which converts it into a signal adapted to control a pneumatic control station 18. The station 18 compares the incoming signal with a standard signal and after amplification uses it to adjust a valve 16 controlling steam supply to a steam heater 2, the heat adjusting the viscosity of the fuel. The tube 20 and the bellows in the transmitter 13 damp out pulsations so that viscosity control is not affected by pressure variations in the fuel system. In Fig. 2 the capillary tubes are formed by grooves in the outer surface of a cylindrical block 30, the tube 8 being a groove 33 extending from a fuel inlet port 32 around the block to an end 34 communicating with a bore 35, and the tube 20 being a groove 37 extending helically from the bore 35 to an exit end 38 which is in communication with the inside of the fuel line. In another embodiment the capillary grooves are spirally formed on a flat plate, Fig. 3 (not shown) adapted to be covered by another flat plate, Fig. 4 (not shown) which may be rotatably movable thereon to shorten or lengthen the first capillary groove according to position.

Patent GB-403698-A (GB)
Title: Improvements in or relating to bonding compositions and to abrasive articles made therewith
Filed: 1932-06-29
Abstract: A fluid or paste-like composition, suitable as a bond in making abrasive articles, is made by mixing coagulated rubber and a heat hardenable liquid, such as a phenol-aldehyde or urea-formaldehyde condensation product, heating the mixture at a temperature lower than that at which the resinous liquid hardens, and continuing the treatment until the mixture is flowable, the rubber being dispersed in the heat-hardenable liquid.  Water may be added and also bentonite or other water absorbent substance.  In an example, a mixture of approximately equal parts of water and a liquid phenolaldehyde resin in the A stage is added gradually to broken down coagulated rubber (e.g. smoked sheets) in a dough mixer, at a temperature beginning at 85-90 DEG  C. and finishing at 30-35 DEG  C., until the proportion of liquid to rubber is approximately 2 to 1.  The temperature is then raised slowly to about 90-100 DEG  C. when the mixture becomes liquid.  If this is allowed to stand, a cream separates out containing about 70 parts of rubber to 30 of resin.  This may be washed to reduce the proportion of resin, or liquid or solid resin may be added.  An alternative method of increasing the proportion of rubber is to add latex or the like to the rubber-resin-water mixture. The composition may be used as a bond for abrasive grains or other fillers.  Vulcanizing agents may be added and the bond may be cured at a temperature which vulcanizes the rubber and hardens the resin. In an example, in the manufacture of an abrasive article, 8 parts of a resin-rubber mixture containing 30 parts of rubber to 70 parts of resin are mixed with 90 parts of abrasive grain and the wet mixture is dried with occasional stirring until the mix becomes tacky.  To this mixture are added 3 parts of pulverized flint, 2 parts of a potentially reactive dry phenol-aldehyde resin and 1 1/2 parts of sulphur.  The mass is moulded at about 2000 lbs per square inch, removed from the mould and cured at about 320 DEG  F. for 12 hours. By using a series of bonds of varying rubber content ranging from 0-100 per cent a series of abrasive articles differing only in the bond may be made.  Specification 360,482 is referred to.

Title: Improvements in or relating to anodes for electron discharge devices

Filed: 1935-06-27
Abstract: 443,075. Grinding. SPEER CARBON CO., St. Mary's, Pennsylvania, U.S.A.- (Assignees of Zitzler, J. A.; St. Marys, Pennsylvania, U.S.A.) June 27, 1935, No. 18464. Convention date, July 3, 1934. [Class 60] [See also Group XL] In the manufacture of unitary or one-piece carbon anodes for electron discharge devices such as thermionic valves, of the box or cathodeenclosing type, two sets of accurately parallel reference planes at right angles to each other are machined upon the outside of a flattened cylindrical carbon blank and the cathode chamber is machined in exact relation to these planes. The manufacture of the anode shown in Fig. 12 is as follows. The carbon blank shown in Fig. 1 is prepared by extrusion and subsequent baking, preferably to graphitizing temperature. The blank is cut to a convenient length by thin carborundum wheels, and the end 8 is then ground plane by pressing the blank in a guide channel and sliding it across the end face of a grinding wheel. Using this as a reference plane, the ends 9, 14 and 15 are similarly ground plane giving the form shown in Fig. 5. The re-entrant faces are then ground true by a wheel having both peripheral and side grinding faces. The blank is fitted into a jig 34, Fig. 7, and the centre roughly drilled out, notches 41 on a sliding base plate 35 co-operating with a plunger 42 to ensure accurate positioning of the drill holes. The control chamber is then milled to the desired shape, and the external corners are rounded off by a curved grinding wheel as shown in Fig. 10. The ribs 14, 15 are drilled to receive the supports 64, 65, Fig. 12, which may be slightly crimped to ensure a firm fit. In other forms of anode shown which may be made in the same manner, the ribs 14, 15 may be dispensed with, or replaced by laterally projecting strips or lugs for attachment to supports. An anode may be provided with two internal chambers. The carbon blank may alternatively be extruded with a rough central aperture, when the drilling step described above becomes unnecessary.

The material is now fully compressed into the box 1 by the plunger 7 and the bale removed after removing the box 1 from the press or opening the box 1 if its walls are formed by doors. Instead of forming the bale with the precompressing plunger 7 a further plunger may be used entering the box 1 from below.
