Title: Improvements in and relating to jig conveyors
IPC: B65G27/00
Filed: 1931-02-26
Abstract: 374,080. Compressed-air engine valve-gear. KLERNER, H., 164, Schalker. strasse, Gelsenkirchen, Germany. Feb. 26, 1931, No. 6086. Convention date, Feb. 28, 1930. [Classes 122 (ii) and 122 (iii).] Cylinders, adapted to act as opposing cylinders in conjunction with driving motors of jig-conveyers such as described in Specifications 271,099 and 273,738, [both in Class 122 (ii), Steam-engine distributing and expansion valves &c.], are provided with primary combined controlling and air-escape ducts 5 and also with secondary air-escape ducts 11 whereby they may be used optionally as opposing or driving- motors. By means of the secondary duct 11 and auxiliary, regulating-valves such as 23, 25, the exhaust from the opposing-motor may be regulated, and the reversal and exhaust of the motor when driving. The duct 11 is provided with a separate auxiliary exhaust valve 4a, the main valve 4 controlling both supply and exhaust. The reversal of valve 4a depends on valve 4. In Fig. 1 the working-piston 2 of the opposing-motor is moving the attached jig conveyer to the left in the conveying direction. The bores 6, 7, 7a of the duct 5 can be closed optionally by valves 8, 9, 9a. The fresh air is supplied through duct 10 ; duct 11 leads to an exhaust port A1 controlled by valve 4a. When the opened duct 7a is passed, the valve 4 is moved to the left, the exhaust A is opened, and then valve 4a is moved to open port A1. The driving-motor moves the conveyer and the piston 2 to the right. When the bore 26 is closed, compression takes place until the valve 4 is moved to the right to open the supply and close valve 4a. When bore 22 is. opened, the apparatus constitutes a driving-motor. Closing the bores 22, 24, 26 makes the valve 4a inoperative ; closing the bores 6, 7, 7a turns the apparatus into a non-controlled opposing cylinder. The valves 4, 4a may be wholly or in part mechanically operated. A non-controlled opposing-cylinder may be arranged on the opposing-motor, Fig. 4. The hollow pistonrod forms an auxiliary cylinder for a piston 2a with a hollow rod through which air is supplied. The air in the cylinder is' forced back into the pipe line by the driving-motor. Ducts 17 and 10a may be connected by a duct 17c whereby after the valve 4a has been reversed a further supply of compressed air passes to the cylinder to ensure the shockless reversal of the raised conveyer. The duct 11 may be closed when the conveyer-is at a steeper incline than 10 to 25‹. Bores 26, 24 may be opened when wet rubbish is to be conveyed. The valve 4a may be used when the controlling duct and primary exhaust, are separate.

Filed: 1964-02-14
Abstract: 991,540. Lasting machines. J. S. KAMBORIAN. Feb. 14, 1964 [March 5, 1963], No. 6314/64. Heading A3B. A method of lasting a shoe including a softened thermoplastic stiffener includes the steps of clamping the upper and softened stiffener against the last and cooling the clamp until the stiffener has reverted to its rigid condition. As described the heel seat lasting machine of Specification 963,724 has a modified heel clamping pad 140. The clamping pad 140 (Figs. 16, 18) has a cavity 146 to receive cooling fluid and has a metal back plate 156 which has brackets 158 extending under the pad 140. The pad 140 has a thin inner wall 149 and thick outer walls 151 so that when cooling fluid is applied to the cavity 146 under pressure the pad will expand inwards to clamp the upper and stiffener against the last. Three methods of cooling the pad are described. In a first embodiment (Fig. 19) cooling fluid in a tank 314, cooled by coils 316 of a refrigeration unit 318 is circulated continuously through the pad 140 by a pump 324. When, in the cycle of the machine described in Specification 963,724 the motor 246 is operated to raise the holddown, a pressure switch 340 is closed to actuate a solenoid 330 which closes a valve 328 in the cooling system so that cooling fluid builds up under pressure in the pad 140. In a second embodiment (Fig. 20) the pressure switch 340 actuates a solenoid 378 to operate a motor 356 which operates a double plunger pump which on its downward stroke pumps fluid along the lines 358, 370 into the pad 140<SP>1</SP>, valve 360 being open and valve 366 being closed so that cooling fluid builds up under pressure in the pad 140<SP>1</SP>. On its upward stroke valve 360 closes and valve 366 opens so that the cooling fluid is sucked from the pad. In a third embodiment (Fig. 21) the pressure switch 340 actuates a solenoid 408 to operate a motor 400 which operates a pump 386 which is cooled by the coils 316<SP>1</SP> of a refrigeration unit 318.

Abstract: 1,177,133. Alumina and silica. INSTITUT OBSCHEI I NEORGANISCHESKOI KHIMII AN USSR. 10 Feb., 1967, No. 6554/67. Heading C1A. In a process of preparing alumina by parallel treatments of nephelite rock and kaolin: (1) Nephelite rock is leached with NaOH in presence of CaO to give a sludge containing Na2OÀ2CaOÀSiO2ÀH2O and an aluminate solution which, after separation from the sludge, is evaporated and cooled to crystallize alkali aluminates; part of the mother liquor (A) being returned to the leaching step. The sludge is treated with NaOH solution to form CaOÀSiO2À NH2O and an alkaline solution which is mixed with the remainder of the mother liquor (A). (2) Kaolin is roasted and leached with this mixture of alkaline solution and mother liquor (A) to form an alumina concentrate which, after separation from the alkali silicate solution (B) also formed, is sintered with limestone and sodium carbonate and then leached to produce belite sludge and an aluminate solution. This aluminate solution, after separation from the sludge, is used to dissolve the alkali aluminates crystallized in stage (1) to form a concentrated aluminate solution from which alumina is obtained by roasting aluminium oxide hydrate precipitated from the solution, e.g. by seeding with Al(OH)3. In one embodimment, the alkali silicate solution (B) obtained by leaching the roasted kaolin is cooled to crystallize sodium silicate, and mother liquor subjected to carbonation to precipitate amorphous silica, which is removed. Sodium carbonate is separated from potassium carbonate in the residual liquor by multi-stage evaporation and is recirculated to the alumina concentrate sintering step in stage (2).

Title: Process for the manufacture of a dried milk preparation suitable for infants
IPC: A23C9/154
Filed: 1936-03-04
Abstract: The process described in the parent Specification is modified by mixing with the milk a sugar other than that produced as set forth in that Specification, the milk being partially evaporated before or after the addition of the sugar, acid, e.g. citric acid, being added after the partial evaporation in sufficient quantity to cause curdling, a protective colloid, e.g. pectin or substances containing it, starch or its higher degradation products, cornflour or gum and glue-like mucilages being also added prior to or at the same time as the acid, the mixture being finally evaporated to dryness.  Acid in quantity insufficient to cause curdling may be added prior to the partial evaporation or prior to addition of the protective colloid. In an example, the sugar in solution which may be slightly acidified is added to pasteurized milk and the mixture concentrated under vacuum as rapidly as possible until the water content is about 20-30 per cent and slowly cooled.  A solution of pectin, citric acid and sugar is made, with stirring in water at 90-100 DEG  C., or by adding the mixed ingredients to cold water and heating with continuous stirring.  A small amount of saccharine may also be added.  The acid jelly obtained on cooling is mixed with continuous stirring and kneading with the sugar and milk concentrate until a stiff mass has been formed, the mass being then dried and ground.  The Specification as open to inspection under Sect. 91 comprises also the use of wheat gluten as the protective colloid and the addition of citric acid in the form of lemon juice.  This subject-matter does not appear in the Specification as accepted.
