Title: Means for compacting a particulate material
IPC: B22C15/12
Filed: 1963-07-01
Abstract: 1,019,809. Moulding machines. R. W. TACCONE. July 1, 1963 [July 2, 1962], No. 26069/63. Heading B3F. A compacting head for use with particulate material (the Figure, not shown), for example, sand moulds, comprises a head frame 2 within which is located a freely movable piston with a thick solid or flexible element 4 at its lower surface. In the lower and upper part of the frame 2 are situated flexible diaphragms 5 and 6 respectively. Air may be independently admitted between the element 4 and the lower diaphragm 5 and between the upper diaphragm 6 and the wall 9 of the head, through pipes 7 and 10 thus forming air cushions in chambers 11 and 12 respectively. The air cushion formed in chamber 12 assures in conjunction with the pressure from the annular rim 8, a compensated distribution of pressure during the initial compacting stage as the head is lowered on to material in the flask 1. With further lowering of the head the air cushion in chamber 11 is compressed which augments the initial compacting forces. The air supply to chamber 11 may be sealed off thus producing desirable increases in pressure applied to the surface of the material. This constant pressure increase is combined with the transverse pressure action produced on the material by the rim on the head.

Title: Process and apparatus for the dehydration of alcoholic solutions
IPC: B01D3/00
Filed: 1940-02-12
Abstract: 534,374. Preparing absolute alcohol. CELEC CORPORATION, Ltd.. and PHILLIPS, S. M. Feb. 12, 1940, No. 2664. [Class 32] In a process for the production of absolute alcohol, which involves the use of a dehydrant liquid, recovery and dehydration of this liquid are effected in a single stage by heating the dehydrant-alcohol-water mixture in a "divided condition to a temperature sufficient to cause both the alcohol and the water to vapourize and separate from the dehydrant. The " divided condition may be brought about by causing the liquid to flow over heated plates as a thin film, or to flow through or around heated tubes, or to be projected in the form of a fine spray, and is such that the alcohol and water will vapourize and separate from the dehydrant at a temperature between 105‹C. and 130‹C. at atmospheric pressure. Specified dehydrant liquids are glycerol and the glycols, either pure or containing water absorbing compounds such as calcium chloride, calcium carbide, potassium carbonate, potassium acetate, potassium laurate and sodium sulphate. A complete plant for the production of absolute alcohol from fermented wort, and in which the process of the present invention is employed, is shown in Fig. 1. Wort from the tank 1 is heated at 3 and passes to a still 5 where heads are distilled off, being condensed at 7 and 8. Alcoholic liquor passes through the line 10 to the rectifying still 11, water being withdrawn by the line 12, and fusel oils at 13 and 15. The rectified spirit, after passing through the reflux condenser 18, is dehydrated in the column 19. Dehydrant liquid from the tank 20a is introduced, in regulated quantity, to the column 19 at 20, at a temperature of about 100‹C., the column being fitted internally with bubbling plates, with superposed plates heated by steam coils, or with heated tubes down the surfaces of which the dehydrant liquid flows. Absolute alcohol is condensed at 21, and a dehydrant-alcohol-water mixture leaves the base of the column 19 and enters the recovery still 23, in which the mixture is spread, as a thin film, upon a series of sloping plates heated to 110‹-120‹C. The alcohol and water are vapourized and pass to a condenser 24, while the dehydrated dehydrant liquid is withdrawn from the base of the still 23, and is returned to the tank 20a, for re-use. Alternatively or additionally, the mixture may be sprayed into the still 23 which is suitably heated.

Title: Improvements in or relating to Closed-Circuit Hydraulic Remote-Control Devices
Inventor: SZEDLACSEK JOZSEF
IPC: B21J7/34
Filed: 1967-01-18
Abstract: 1,178,173. Drop hammers. DIOSGYORI GEPGYAR. 18 Jan., 1967, No. 2673/67. Heading B3H. [Also in Division G3] A power hammer comprising a tup 15 has a manual control lever 1 which, when moved clockwise, engages a plunger 2 to pressurize an hydraulic telemotor link 3, 8, 9 to move a spool 11 leftwards to vent the space 12 above a double-acting piston coupled to main spool 13. The latter rises with the piston to supply air to the space above the tup causing the latter to move downwards, anvil 19 being simultaneously driven upwards. Lever 18 provides a follow-up action by allowing plunger 17 to move leftwards to depressurize the telemotor link thereby restoring spools 11, 13 to their null positions. The inward movement of the tup is thus proportional to the movement of lever 1. To retract the tup, the lever 1 is moved counter-clockwise to engage a plunger which pressurizes telemotor link 20, 26 to move spool 28 to vent the space below the piston of the main spool 13. The downward movement of the latter reverses the connections to the tup piston and the tup rises. In this case, the lever 18 actuates spool 22 to depressurize link 20, 26.

Abstract: 899,115. Glass - melting furnace walls. GLACES DE BOURROIS. Jan. 26, 1961, No. 3092/61. Class 51 (2). [Also in Group XXIII]. For the drawing of sheet glass, a vitreous melt produced in a tank furnace to give a depth of melt in the range 120 to 150 centimetres, has a high temperature zone at a refining portion and a stream of liquid glass is withdrawn from the melt through an outlet in the furnace at a distance less than 15 metres from the high temperature zone and from which continuous sheet of glass is drawn, a descending flow of glass diverted from the surface stream being cooled to accelerate the velocity of the descending flow and consequently the velocity of the surface stream. A tank furnace 5 for molten glass 10 comprises floor 16, arched roof 13 and terminal wall 12, furnace gases being admitted through ports 17. The floor 16 between the hot point 11 of the furnace and the wall 12 has a heat-insulating coating 15 to reduce heat losses in the return current 27 of liquid glass deflected from the supply current 22 flowing towards the feeding channel 24 and drawing chamber 25, the return current being deflected downwardly at 26 along the terminal wall 12 and upwardly at 28 towards the hot point 11. To accelerate the flow of glass currents, the descending current 26 is cooled by cooling the wall 12 by cold air blown through pipes 19 against the outer surface 18, the thickness of the wall being only about 15 cm. The wall 12 is situated less than 15 m. from the hot point 11 and has its upper edge 20 about 30 cm. below the surface 46 of the bath 10 when the bath is about 150 cm. deep. The depth of the stream 23 supplying the feeding channel 24 and drawing chamber 25 may be varied by means of a register 21 formed by a plurality of individual vertically adjustable blocks 29, each block 29 being screwed to clamping plates securing a suspension rod 30. Each rod 30 passes through a friction bushing 43 in the web 31 of a channel iron 32 supported on posts 33 to straddle the channel 24 and abut the top wall 41 of the furnace 5. The roof 35 of the channel 24 is provided with a slot which acts as a guide for the blocks 29. Each block 29 may be raised or lowered manually or by automatic devices to regulate the depth of the stream 23 throughout its width and thereby compensate for variations in thickness of the drawn glass sheet. The blocks 29 may be made of corundum, mullite or zirconia for temperatures in excess of 1200‹ C. or vitreous silica for temperatures between 1000‹ C. and 1200‹ C.
