Title: Discharge valve, particularly for water closets
IPC: F16K7/07
Filed: 1965-03-11
Abstract: 1,106,961. Water closets. S. A. J. LILJENDAHL. 11 March 1965 [16 March, 1964], No. 10418/65. Heading E1C. [Also in Division F2] A valve adapted to be fitted in the discharge conduit of a water closet bowl in the bottom portion of which a quantity of water is maintained by the valve being in its closed position, there being a partial vacuum existing in and acting on the discharge side of the valve, comprises a resilient sleeve 7 mounted on a pipe 1 part of which is cut away along line 4, the sleeve being deformed when a vacuum exists within the pipe to engage a ridge 3 in the pipe. In the working embodiment of Fig. 5, the sleeve is formed with lugs 21, 22 in which are fastened pins 23, 24 which engage, with lost motion, arms 25, 26 carried by spade-like members 27, 28 attached to a housing 29 carrying a weight 30, the housing being flexibly attached at 33 to a fixed housing 31 connectable via 32 with a vacuum source or atmosphere. To open the valve, a vacuum is created in the housings 29, 31 causing the latter to move upwardly and thereby open the valve. Closure is effected by venting housings 29, 31 to atmosphere. In the embodiment of Fig. 6, the connection 32 is made via two-way cock 37 to the downstream pipe 11, and the sleeve is replaced by a resilient domeshaped member 43 fastened at its perimeter 45 to the pipe, which in this case is in the shape of an inverted 'U' the top of which has been removed. As shown in Fig. 7 the spades 27, 28 need not pinch the resilient member against the pipe wall since the vacuum existing in the downstream side will suffice to produce a closure where the member adopts the shape shown. The downstream side of the resilient member is preferably thicker or stronger than the upstream side; the ridge need not be perpendicular to the axis of the pipe and the closing points represented by the spades may be assymetrical with respect to the ridge. The diameter of the pipe at the closure point may be less than that on the downstream side.

Title: Improvements in or relating to change-speed mechanism
IPC: F16H29/08
Filed: 1949-04-20
Abstract: 670,285. Variable-speed gearing. SCHMITT, G., and ROGGEN, M. VAN. April 20, 1949 [April 28, 1948], No. 10445/49. Class 80 (ii). The fulcrum 5 of a lever 4 oscillated by a rotary driving crank 2 and connected by a link 6 to a driven crank 9 oppositely rotating a shaft 11 through a one-way clutch 10, is mounted on a control arm 12 so as to be movable to vary the speed ratio, the axes of the members 5, 11 being on opposite sides of the link 6 and the latter always dividing the line between the axes in such a ratio that the product of this ratio and the speed of the point of articulation 7 between the link and lever is a constant, a geometrical analysis being given to illustrate that the speed of the crank 9 may then be made to bear a constant relation to that of the crank 2 over a given power stroke, up to at least 90 degrees of arc. As shown, the necessary cycloidal path of movement of the fulcrum 5 to ensure that such relations exist for all speed ratios is approximated to the are of a circle and the arm 12 is a lever with a pivot 13 near the axis of revolution of the crank 2. The link 6 is of the same length as the distance between the points 5 and 7 so that the speed ratio may be reduced to zero by bringing the lever 4 into line with the link 6. In Fig. 8 (not shown) the lever 12 is fulcrummed about the axis of the crank 2 and the link 6 is longer than the distance between the points 5 and 7. In practice, the arrangement is quadruplicated to give a smooth power flow throughout the cycle of operations. The actual output shaft may be placed in any position, regardless of the theoretical considerations governing the disposition of the axis of the shaft 11, by connecting the crank 9 and output shaft through a parallelogram linkage. Either a reversing-gearing or a two-speed direct drive and countershaft gear may be placed behind the main gearing in series therewith.

Title: Water-soluble high molecular weight polymers and process for their production
Inventor: LLOYD WILLIAM GILBERT
IPC: C08F8/00
Filed: 1960-03-24
Abstract: Water-soluble polymers containing aryl nuclei substituted by onium groups are obtained by reaction of an emulsion or latex of a vinylbenzyl halide polymer with an organic compound free from active hydrogen and which is capable of reacting with the benzyl halide groups with the formation of onium groups.  The vinylbenzyl halide polymer may be a homopolymer, or a copolymer with styrene, alkyl styrene, acrylonitrile, methyl acrylate or a methacrylate, or may be a cross-linked polymer, e.g. with up to 1% of a polyethylenically unsaturated cross-linking agent such as divinyl benzene.  Suitable polymer latices are described in Specification 880,338.  The preferred onium groups may be represented by the following formul ; -H2C-SR1R2Y, -CH2-NR3R4R5Y, -CH2-PyY, -CH2-QY, -CH2-IQY and -CH2-MY, wherein R1, R2, R3, R4 and R5 are alkyl or hydroxyalkyl, R1 and R2 may represent polymethylene, Py is pyridinium, Q is quinolinium, IQ is isoquinolinium, M is morpholinium and X is chlorine or bromine. Specified organic compounds free from active hydrogen are tertiary amines optionally containing hydroxy alkyl substituents, morpholine, pyridine, quinoline, isoquinoline and their alkylated derivatives and organic sulphides.  The examples illustrate the preparation of various water-soluble products containing onium groups, said products being stated to be useful as aqueous gelation agents.

Title: Improved device for the continuous analysis of hot, dust-bearing gases
IPC: G01N1/28
Filed: 1958-04-01
Abstract: The wall of the reaction chamber 1, the gas atmosphere of which has to be examined, has an aperture 2, to which there is fitted by means of an airtight joint a jacketed pipe 3 to provide for water cooling. Hot gas from the reaction chamber 1 moves as shown by the arrows and is cooled during its passage along the water-cooled pipe 3.  A sampling current of the gas is withdrawn through aperture 4 by slight uniform suction supplied by a pump 5, avoiding the entry of any infiltrated air.  The length of the pipe and the water cooling of it are such that the gas initially at the temperature in the reaction chamber 1 leaves the pipe through the aperture 4 at such a temperature that the thermal effect is not able either to upset the filter device or the proper operation of the analyser.  The sample gas sucked through the aperture 4 passes first through a de-dusting filter band 6, arranged in a guide frame 7, <PICT:0829267/III/1> located in front of or built into the aperture 4, with packing to prevent infiltration of air.  The band 6 moves slowly across the aperture 4, preferably at a speed capable of being adjusted in accordance with the average quantity of dust occurring in the waste gas.  On either side of the aperture 4, or above and below it, as shown, there are reels 8 to and from which the filter strip 6 can be automatically wound or unwound in a manner similar to that of the ribbon on a typewriter, guide rollers or pulleys 9 directing the strip to and from the aperture.  Dust deposited on the filter strip as a result of the passage through the filter of the sampling current of gas may be automatically removed by suction applied through nozzles 10.  The continuously moving filter strip used in the above modification may be replaced by a rotatable filter disc but in both cases the filter area should be considerably greater than the cross-sectional area of a pipe leading the filtered gas to the analyser.
