Title: Improvements in and relating to diaphragm valves
IPC: F16K7/12
Filed: 1940-02-17
Abstract: 538,208. Diaphragm valves. SAUNDERS VALVE CO., Ltd., and SUTTON, F. Feb. 17, 1940, No. 3058. [Class 135] A diaphragm valve of the "weir" type has the movement of the diaphragm compressor in the valve closing direction limited by a stop. In the form shown in Fig. 2 the casing opening opposite the weir 3 is surounded by an upstanding hollow cylindrical extension 7 to which the bonnet is secured. This bonnet is externally screwthreaded to engage the extension and internally threaded to engage an actuating screw 13. The inner end of the screw 13 has a collar engaging an undercut recess in the valve compressor which is slidably mounted in the bonnet. The diaphragm is clamped against an internal flange in the casing by the lower end of the bonnet bearing against an L-section ring embracing the diaphragm. This ring by engagement with the lower 'face of the compressor serves as the stop to prevent undue closing pressure being applied to the diaphragm. In a modified form constructed as a pillar cap the lock-nut 15 on the bonnet is replaced by a protective cap. In another form in which the diaphragm is clamped between two flanged parts splaying of the diaphragm is prevented by the L-section ring which is formed with radial fingers to support the diaphragm in the valve open position. The diaphragm compressor also has radial fingers adapted to pass between the support fingers until extensions on two of them opposite the weir contact with parts of the upper surface of the L-section ring and so prevent further movement. Specifications 321,892, [Class 135], 362,084, 434,664, 431,665, 434,684, 439,701, 442,790, 468,664, 516,526, 516,569, 517,887, 518,286, and 527,938 are referred to.

Title: Improvements in combined calendar and money box, savings bank or other collection box
IPC: G07F17/16
Filed: 1928-02-02
Abstract: 316,630. Hepworth, G. A., and France, H. W. Feb. 2, 1928. Date indicators.-A monev or other collection box combined with a calendar comprises a receptacle for coins formed with coin-slots and containing movable sets of date inscriptions and provided with means whereby on the insertion of a coin two or more of the sets of inscriptions are or can be altered or moved simultaneously. In the form shown, Figs. 1 and 2, the collection box is constituted by a casing 1 with coin slots 12, 12<1> and a frame work 2 supporting rollers 3, 4, and 5, and twopart coin hoppers or receivers 13, 13<1>, 14, 14<1>, Fig. 3. The rollers 3, 5 bearing the names of the days of the week and the months respectively have the inscriptions marked thereon and the roller 4 carries an endless band 8 passing over guide pulleys 10, 11 with the date figures inscribed theneon. The rollers 3, 4 are coaxial but are manually adjustable to set the calendar at the beginning of each month. For this purpose a pin 28, Fig. 5, carried by a collar 29 on the shaft 3' of the roller 3 registers with holes in the opposing ends of the rollers 3, 4 and is longitudinally movable, against the action of a spring 32, by a press knob 31 on a sleeve 30 surrounding the shaft 3<1>. When the pin 28 is withdrawn from the end of the roller 4 the knob 31 is turned and a pin 33 on the sleeve picks up a pin 34 on the roller 4 to effect its adjustment. The two parts of the coin receivers are mounted coaxially the parts 13<1> and 14<1> being integral with a manually operable member 22 extending through a slot in the back of the casing. The receivers have duplicate recesses 26, 27 of tapered formation which may extend through the receiver or only partially therethrough, so as to retain a coin therein which coins acts as a coupling between the parts 13, 14 and 13<1>, 14<1> respectively. Rotation of the receiver 13, 13<1> by the member 22 causes rollers 17 thereon to operate a spring controlled lever 16 carrying a pawl 15 to actuate the ratchet wheel 18 of the roller 5. Similar ratchet and pawl mechanisms actuates the roller 3. To ensure the correct positioning of the receivers after each operation a spring pressed arm 24 engages a pair of rollers 25 on the member 22 and the rollers such as 17 associated with the pawl carrying levers are also arranged in pairs. In a modification (not shown) the two part coin receivers are dispensed with and the act of thrust. ing the coin through the slot causes, directly, the ratchet mechanism to impart rotary movement to the rollers or to indicating discs.

Title: Method of providing a controlled atmosphere containing nitrogen or a mixture of nitrogen and hydrogen
Inventor: ROSENBLATT EDGAR FRITZ
IPC: C01B3/00
Filed: 1951-02-14
Abstract: <PICT:0676287/III/1> A controlled atmosphere of nitrogen or nitrogen and hydrogen is obtained by passing a mixture of gaseous ammonia and free oxygen - containing gas, wherein the molecular ratio of NH3 to O2 is greater than 4:3, over a supported catalyst comprising at least one metal of the platinum group, e.g. 0.5 per cent by weight platinum, rhodium, ruthenium and/or iridium deposited on dehydrated alumina or zirconium dioxide.  A proportioned mixture of ammonia and air containing at least 21.83 per cent ammonia is passed into the top of the catalyst chamber 16 through a bed of catalyst 29.  The frusto-conical shape 30 ensures that regardless of the amount of ammonia feed there is always a zone in which optimum oxidation efficiency is obtained.  After condensation of water, the exit gases are mixed with a controlled amount of air and passed over a supported palladium catalyst bed 33, heated to 100 DEG C or more by heat exchange with the gases coming from bed 29, to remove any nitrogen oxides and adjust the hydrogen content.  Water is again condensed out.  Where nitrogen alone is the product the catalyst metal is essentially platinum for combustion, but where a nitrogen-hydrogen mixture is the product then rhodium, ruthenium, and/or iridium are also used for cracking and the catalysts may be in single or separate beds.

Abstract: 1,261,042. Ion exchange. CRANE CO. 22 Jan., 1969 [23 Jan., 1968], No. 3627/69. Heading B1J. Ion exchange apparatus containing a fixed bed of ion exchange material during at least service flow is operated according to a method which is designed to reduce leakage from the ion exchange material during service flow of ions which have been exchanged on to the ion exchange material during previous service flow but which have not been removed from bed of ion exchange material, after regeneration thereof; such method comprises the steps of (a) recycling a plurality of time through the bed of ion exchange material, after regeration thereof and in the direction of service flow, a composition which removes by mass action from the ion exchange material at the. service flow exit end of the bed the ions liable to such leakage and which relocates these ions on the ion exchange material at the service flow inlet end of the bed and (b) thereafter rinsing the bed to remove the composition which has been recycled therethrough. The composition, which may be recycled through the bed at a temperature exceeding the temperature of normal service flow, may be provided by dilution of the regenerant used for regeneration of the ion exchange material of the bed. As exemplified, ion exchange apparatus is operated in a manner such that service flow and rinsing after recycling each is effected by downward flow through a bed of ion exchange material and regeneration is effected either by downward flow through the bed, see Figure 1 (not shown) or by upward flow through the bed, the regenerant being removed from the bed at a level below the top of the bed, see Figure 2 (not shown), the composition which is to be recycled being provided in each case by dilution of regenerant by the addition thereto of diluent water prior to the passage thereof through the bed. Reference also is made to various other modes of operation in respect of the direction of flow through the bed during service flow, regeneration and rinsing after recycling.
