Title: A method of producing silica gels of high water stability for use as drying agents
Inventor: DULTZ JURGEN
IPC: B01J20/10
Filed: 1965-11-10
Abstract: Silica gel is prepared by mixing an acid solution and an alkali metal silicate solution containing 27.5-31% by volume, based on the dried gel, of pulverulent additives of 1-5 m  diameter to form a hydrosol, coagulating the hydrosol to a hydro-gel and immediately cooling the gel, then ageing in an aqueous solution for 1.5-7 hours below the gel-forming temperature, effecting base exchange for removal of trapped alkali metal ions, washing and calcining at 300-450 DEG  C. The coagulation may be effected by dispersing the hydrosol in a H2O-immiscible liquid, e.g. mineral oil, and leaving until gel formation occurs.  The pulverulent additive may be silica gel powder or SiO2/Al2O3 gel powder.  The silicate solution may be mixed with an acid solution of an Al salt to form a gel containing up to 3% Al2O3. The gel particles may be aged at 4 DEG  C. and the base exchange may be effected by washing with dilute Al2(SO4)3 solution or dilute H2SO4.

Title: Method of producing mineral water
IPC: C02F1/68
Filed: 1972-10-18
Abstract: 1380636 Method and apparatus for producing mineral water MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 18 Oct 1972 [1 Dec 1971] 48019/72 Heading B1C [Also in Division Cl] In a method of producing mineral water a source water is mixed with carbonic acid gas under a predetermined pressure so that carbonated water is produced, this is then mixed with one or more water insoluble mineral compounds each containing a mineral component being soluble in acid so that the mineral components dissolve and the carbonated water becomes mineral water. Fig. 3 shows a carbonating element and comprises a body 10, a carbonic acid gas inlet 11, a source water inlet 12, a carbonated water outlet 13, a carbonic acid gas pressure adjustment 14 and a lever 15, Fig. 4 shows a mineral mixing element to be combined with the element of Fig. 3. It consists of a tank 20 having a carbonated water inlet 21 and an outlet 22. There is a filtration element 24 having a housing 25 divided in two by a perforated plate 30 on which a layer of granulous or powdered filtration material such as mineral carbonate is formed. A filtration cloth element 32 surrounds the inner end of pipe 22. The carbonating element operates as follows. Liquidified carbonic acid gas flows from a carbon dioxide tank 18 trough filter 55 to a reserve chamber 48. The aim is to maintain a predetermined primary pressure in chamber 49. When the pressure drops slightly in this chamber spring 61 moves push rod 58 leftwards to allow carbonic acid gas to pass along groove 57 and through opening 52. In chamber 49 the carbondioxide gasifies to increase the pressure therein. When the rightward forces on the push rod 58 exceed spring 61. The push rod is restored to close opening 52, the gasified carbonic acid gas passes through conduit 83 to a first annular groove 80. Source water is supplied to inlet 12 and flows through conduits 86, 86' to a third annular groove 82. Lever 15 is initially rotated so that rod 87 presses sheet 68 onto the bottom of recess 66. This separates central recess 69 from first annular groove 80, and second and third annular grooves. 81 and 82 from each other. When lever 15 is rotated to move rod 87 to the left pressurised carbonic acid gas in groove 80 flows beneath sheet 68 into recess 69. The gas passes from the recess through conduit 70 to inlet port 71 of valve 72. Element 73 is set to maintain a constantgaseous pressure in chamber 76. The gas then flows through outlet port 79 to conduit 84 and thus into groove 81. Since, at this instant, source water in groove 82 flows beneath sheet 68 into groove 81, the source water is mixed with the gas in groove 81 and carbonated. The carbonated water is delivered through conduits 85, 85' to outlet port 13:

Title: Rotary variable volume pump
IPC: F04D/
Filed: 1962-12-28
Abstract: 984,255. Rotary variable volume pumps. HARTMANN MANUFACTURING CO. Dec. 28, 1962 [Jan. 11, 1962], No. 48730/62. Heading F1F. In a variable volume pump having a housing 10 with fluid inlet and outlet means, 13 and 14 respectively, and a rotor 12 with vanes 63 and side plates 59, 61 rotatable with the rotor and spaced from the housing, a port ring 18 is arranged guided on its opposite faces by the housing 10 and being slidable between said side plates under influence of a control member 31, the ring having passageways in communication with inlet 13 and outlet 14. As shown, fluid entering the pump at inlet 13 flows into the space 11 surrounding the port ring 18 and flows via port 17 into the pump working chamber from which its exits at 21, flowing into outlet 14 via passageways 22, 26, 27 in pin 23. Vanes 63 are slidably disposed in their vane slots and fluid openings 64 allow fluid being pumped to flow to the radially inner end of the slots so that fluid pressure may be applied to the base of the vanes to hold the vanes against the inner periphery of the port ring 18 (Fig. 3, not shown). The vanes 63 are chamfered so that the vane bases have a radially outwardly projected area greater than the radially inwardly projected area of the chamfers. The port ring 18 has fluid pockets 51, 52 so that outlet fluid filling these pockets will help to balance the pressure on the said ring. In practice, to vary the volume of fluid flowing through the pump, screw 39 is turned which moves plunger 41 through spring 36 so that the port ring moves e.g. to the left and thus increases the flow volume through the pump. Plunger 44 is used as a limit control and may be adjusted by screw 43. Two pumps of the type described may be arranged in tandem as shown in Fig. 2.

The valve stems 13 are secured to inner tubes 12 or to the covers themselves in the case of tubeless tyres. They are held in the bores 14 by spring loaded plungers 30, when a cam (41), Fig. 3 (not shown) is withdrawn from a roller 39 as the member 5 is rotated and a pressing member 78 including a stop member 81 may also be provided to assist the operation of the locking mechansim 26. The inner tube is evacuated by a suction pump attached to a tube (25). The valve cores are supplied from a feeder 45, via a shoot (47), Fig. 2, to a feed tube 51, Fig. 5A, the required number of cores being accumulated in the shoot (47) by means of a photo-detecting arrangement. Each core is inserted in its stem by a screw drive bit 64, which is actuated by an air motor 60. The bit 64 is mounted in a guide tube 68, which is slidably mounted to engage the valve stem 13. When the valve core is screwed into the valve stem, the motor 60 retracts the bit 64 and tube 68 and the stop member 81 is also withdrawn. The assembled valve core and stem are conveyed to a detecting mechanism 82 which detects whether the core is correctly mounted in the stem. Should the stem be incorrectly mounted or absent, a disengaging mechanism 105 ejects the valve stem from the annular member 6 by pressing down the roller 39 to raise the plunger 30, thereby allowing a pneumatically operated rod (107) to press out the valve stem, Fig. 7 (not shown). Further screwing mechanisms 108, 109 may also be provided to ensure that the valve core is fully screwed home and the assembled core and stem are ejected from the member 6 by a mechanism 115. Pressing members 102, 113, 114 may also be provided if required.

Title: Improvements in high density storage and retrieval system
IPC: H03M7/14
Filed: 1970-10-19
Abstract: 1294397 Digital data stores HONEYWELL INFORMATION SYSTEMS Inc 19 Oct 1970 [27 Oct 1969] 49505/70 Heading G4C In a magnetic recording system data is recorded as a pattern of flux reversals along a track, the pattern occurring within a cell of n possible flux reversal positions uniquely representing a group of n-1 binary digits. The relationship between the patterns and the bits is such that for any train of bits no more than two adjacent flux reversal positions occur without a reversal taking place. The patterns are self-clocking and allow error detection. Fig. 2 shows the patterns corresponding to 3-bit groups. The read in/read out circuitry is illustrated in Figs. 5 and 6 (not shown). Write mode.-Successive groups of 3 bits, e.g. from a data processor, are placed in a 3-bit data register (55) which feeds a coding circuit comprising AND and OR gates (58-75). The coding circuit is also fed with 4 sequential clock pulses (DCTO-DCT3) from a counterdivider (44) driven by an oscillator (18). The coding circuit controls a bi-stable (78) whose output, a 4-bit signal having bit transitions corresponding to the relevant flux reversal pattern, Fig. 3b, passes to the recording head of a magnetic disc. Read mode.-The signal from the read head is passed to a 4-bit register (94) via AND gates (90-93) energized sequentially by clock pulses (DCTO-DCT3) from the counter divider (44). In this mode the divider is fed by an oscillator (34) synchronized by transitions in the signal from the disc. The register (94) provides a parallelbit signal to a decoder comprising AND and OR gates (96-104) which feeds the corresponding 3-bit signal via the data register (55) to the data processor. Error detection.-Since each permitted flux reversal pattern has a reversal at least in position T0 or T1, and in position T2 or T3 an error can be detected by a circuit, Fig. 8 (not shown), which indicates when bits 1 and 2 or bits 3 and 4 of the 4-bit signal held in the register (94) are both zero.
