IPC: B65D83/14
Filed: 1968-04-04
Abstract: 1,217,524. Pressurized dispensing containers. C. G. SIEBEL. April 4, 1968 [April 15, 1967], No. 16299/68. Heading F1R. In a pressurized spray pack comprising a container closed by a cap formed with an outwardly convex dome, and a valve which is sealed against an aperture in the dome with the aid of a resilient valve sealing ring and which has an actuating mem - ber passing through the aperture, the edge of the aperture is rounded by being folded back on itself. The valve is of the type comprising a resilient and seal ring 3, Fig. 1, clamped between a valve housing 4 and the dome 2 of the cap 1 by a scrageing or crimping 6, a radial bore 12 in a valve stem which is normally closed by the seal ring being opened when the seal ring is deformed by depressing the valve stem. The edge 14 of the aperture 10 in the top of the dome is rounded by rolling the edge over as shown in Fig. 3. The cut face 18 of the edge 14 is thereby protected from atmospheric corrosion which might spread from the face under the layer of tin or enamel on the outer surface of the cap. The rounded edge provides an easy guideway for the valve stem and avoids damage of the seal ring 3. Any product diffusing through the seal rings 3 from the underface 16 is collected in a space 17, where it builds up a pressure which gently reduces the rate of diffusion. As shown, a part of the edge 14 may lie in a plane lying above the main part of the outside of the dome.

Title: Improvements in and relating to manometers or pressure-indicating instruments of u-tube type
IPC: G01L7/18
Filed: 1935-06-05
Abstract: 440,707. Liquid-level pressure gauges. ALEXANDER, W., 167, St. Vincent Street, Glasgow. June 5, 1935, No. 16308. [Class 106 (ii)] Comprises a particular construction of U tube gauge using two immiscible liquids. The narrow indicating tube 1 contains in its lower portion the lighter indicating liquid A which extends down to to the heavier liquid B in the tube 2 of wide bore. The heavier liquid fills the connecting tube 3 and part of the wide tube 4 of the other limb which also contains the lighter liquid B. Above the lighter liquids in each limb is air, gas, &c. At " zero " or " equal " pressures in the limbs, the liquids will be at " zero " level, viz. 5 in tube 1 and 7 in tube 4. At high pressure, the levels will be at 8 in tube 1 and 10 in tube 4. The pressure difference is read on the scale S. In the example shown, the device is used for measuring the depth of liquid in a tank. A pump 16 is connected through a three-way cock to the gauge and to a bell 13. Air is pumped into the bell until it bubbles up through the tank and then the cock is turned to connect the gauge with the bell. A third position connects the legs for zeroizing. If the tank is under vapour pressure above the liquid, an additional pipe 15 is fitted. Further, still lighter liquid may be placed above the light liquid for protection purposes.

Title: Improvements in or relating to processes for the recovery of riboflavin
IPC: A61K31/525
Filed: 1947-06-20
Abstract: Riboflavin is recovered in the form of a precipitate of a reduction product of riboflavin from large volumes of solutions of the type commonly encountered in its commercial production by the addition to such solutions, preferably in the presence of an inert gas, of a soluble reducing agent having an E DEG  which is less negative than -0.15 volt to produce in said solution an Eh corresponding to a value between +0.050 and -0.400 volt.  Reducing agents mentioned include titanium trichloride, stannous chloride, sodium dithionite, hypovanadous sulphate, hypovanadous chloride, chromous chloride and chromous sulphate.  In carrying out the invention, the solution containing the riboflavin is first filtered, then treated with the desired reducing agent, preferably at a temperature between 20-30 DEG C. in the appropriate amount to give an Eh which lies within the range set out above. The insoluble reduced form of riboflavin precipitates and is allowed to stand before being separated from the solution.  A preferred method of separation is by the process described in Specification 621,468.  Examples are given of conditions of precipitation and separation of the insoluble reduced riboflavin. In the separation process referred to above it is stated to be an advantage if the precipitation is effected in the presence of a non-absorbent type of finely divided diatomaceous earth. Specification 621,469 is referred to.

Title: Improvements in and relating to journal bearings in machine tools
IPC: F16C17/22
Filed: 1938-06-02
Abstract: 501,109. Bearings. KEARNS & CO., Ltd., H. W., and KEARNS, H. W. L. June 2, 1938, No. 16522. [Class 12 (i)] A bearing for a machine tool is provided with an electrical heating element adapted to heat a part of the bearing so that the expansion of such part alters the diameter of the bearing surfaces. As shown, a bearing cap b is clamped to the base a by bolts c or d<1>. The bolt c is hollow and contains a heating element g. When the speed of rotation of the shaft e is increased the heating element g is energized to heat and expand the bolt c and thus increase the diameter of the bearing. Alternatively, the heating element i<1> may surround the bolt d<1>. In a modification the heated part of the bearing may comprise a sleeve inserted between the head of the cap bolts and the cap. In this case the heating element would be energized when the shaft e is running at low speeds so that the expansion of the sleeve causes reduction in the bearing diameter. The switch for controlling the electrical circuit of the heating element may be linked to the clutch, actuation of which causes a change in the speed of the shaft.

Title: Regeneration of ion exchangers
IPC: B01J49/00
Filed: 1947-06-25
Abstract: 641,962. Purifying liquids. DORR CO. June 25, 1947, No. 16764. Convention date, June 19,1942. [Class 46] The process of utilizing regenerant chemical remaining in an ion exchanger bed towards the end of the regeneration phase by collecting this remainder in a sequence of volumes of different concentrations is characterized by passing wash water through the bed; collecting the first portion of the effluent liquid which has a concentration of the unspent regenerant nearly as high as that of the regenerant, thereafter separately collecting a portion in which the regenerant is, considerably diluted with wash, water, concentrating this second portion by adding regenerant until the concentration is higher than that of the first portion, and using the first, less concentrated, and the second, highly concentrated, solution, one after the other, for regenerating a bed. As shown, a zeolite exchanger X is assumed to be exhausted and to contain wash water only. Twice - used regenerant sodium chloride solution is passed through it from a tank D, and the effluent removed for by-product recovery or the like. Next an equal quantity of once-used regenerant solution is passed through the exchanger from a tank C, displacing the D solution (now thrice-used) to waste or for recovery of by-products or the like. Then a quantity of fresh regenerant solution is passed through from a tank B, displacing the C solution (now twice-used). This displaced solution may therefore be collected in the tank D for the first phase of the next regeneration cycle. Wash-water from a tank A is now passed through the exchanger, displacing the B solution (now once-used). This displaced solution may therefore be collected in the tank C for the second phase of the next regeneration cycle. On passage of a further quantity of wash water through the bed, the displaced liquid consists mainly of the first wash-water but it does contain a small residual concentration of regenerant, and a volume of it sufficient to fill a tank E is collected, the remainder being run to waste. Sufficient regenerant chemical is introduced into the tank B to make up a solution having the same total molar concentration as the solutions in tanks C and D. The recovered dilute solution from the tank E is used, however, to effect solution in tank B. The latter must therefore be made slightly larger than either of the tanks C, D to maintain the required effective molar concentration.

Abstract: 475,258. Feeding blanks. HEYMAN, M. D. June 16, 1937, No. 16774. Convention date, June 20, 1936. [Class 100 (i)] A feeding mechanism, which is especially applicable for feeding small irregular shaped pieces of stock such as mica to a punch press, comprises a support, e.g. an intermittently rotated table 35 which is painted or otherwise marked to form a series of replicas 46 of the parts produced by the press, and means are provided for transferring irregular shaped blanks 46a placed over the replicas 46 to the press B and for delivering the finished articles from the press. The blank-transfer mechanism is actuated from a shaft 21 mounted in an auxiliary frame attached to the punch press platen A supporting the die B. The shaft 21 is driven by means of a pulley 22 which may be driven from the punch press, the driving being controlled by a clutch 23, 26 which is normally kept open by a spring, but is closed by depression of a pedal 32 connected to a lever 29. The press is driven by a one-revolution clutch which is thrown in by a cam 93 on the shaft 21, so that the press continues to operate only when the pedal 32 is depressed. The blanks are transferred to the press by an oscillating suction arm 47 which is operated by a cam 51 on a reciprocating rod 50 actuated by a crank 48 on the shaft 21. The air pressure in the suction arm is controlled by a valve actuated by a cam on the shaft 21, and the valve is connected to a suction pump 97 operated by a motor 98. After the punching operation, the finished article is delivered by an oscillating suction arm 59 which is operated from a lever 62 actuated by a cam on the slide 50. The waste products of the press are removed by means of an air blast delivered by a nozzle 138 under control of a cam on the shaft 21. The table 35 is attached to a ratchet wheel 37 operated by a pawl 44 on a spring- controlled rod 43 reciprocated by a cam 40 on the shaft 21. The blanks may be lightly held to the support 35 by suction of such a degree that the blanks are readily taken therefrom by the blank-transfer means which grip the blanks with a greater pressure.
