Title: Improvements in or relating to reciprocating pumps
IPC: F02B1/04
Filed: 1964-06-22
Abstract: 1,068,863. Reciprocating pumps and motors. ROYAL INDUSTRIES Inc. June 22, 1964 [April 14, 1964], No. 25692/64. Heading F1A. A concrete pump, e.g. for mounting on a lorry, comprises two hydraulically or electricallyactuated pump pistons 14a, 15a operating 180‹ out of phase and drawing from a common hopper and discharging to a common delivery line 19 under the control of a butterfly valve 21, operated automatically when both pistons are stationary at the ends of their strokes. In the hydraulically-actuated embodiment shown, the engine of the lorry carrying the pump drives an auxiliary pump 30 supplying actuating liquid to motor cylinders 14d, 15d via a manually-controlled volume control valve 48 and a reversing valve 57 hydraulically actuated by pilot valves 77, 78, which are actuated by the motor pistons at the end of each stroke through tappets. The right-hand ends of the motor cylinders are interconnected by passage 94 having a relief valve 55, so that the working stroke of one piston effects the return stroke of the other. Butterfly valve 21 is actuated by a hydraulic motor 22b supplied by an accumulator 74 under the control of pilot valves 77, 78. The connections to motor 22b are reversible by a manual valve 67 to position valve 21 so that the pump acts to draw concrete from discharge line 19 and return it to the hopper to facilitate cleaning. Lubrication and cooling of the pump cylinders is effected by water supplied via pipes (83) and (82) Fig. 3 (not shown). The pump casing and the valve housing are readily dismantled for cleaning. Valve 21 is constructed to cut through obstructions. The lorry engine driving the hydraulic circuit may be remotely controlled to vary the pump output.

Patent GB-384006-A (GB)
Title: Method of and means for producing photographic sound records
IPC: G11B7/00
Filed: 1931-09-14
Abstract: 384,006. Optical sound-recording apparatus. SIEMENS & HALSKE AKT.- GES., Siemensstadt, Berlin. Sept. 14, 1931, No. 25763. Convention date, Sept. 13, 1930. [Class 40 (ii).] Relates to processes for producing photographic sound records of the variable-width type, in which volume and frequency are independently recorded. According to the invention, the volume is recorded as differences in density between the two " halves " of the negative record (i.e. the portions separated by a line of wave form), that portion which is normally unexposed being subjected to a variable exposure. The exposures of the two halves of the record are preferably so arranged that they vary by the same amount in opposite senses, and both lie between the upper and lower bends of the photographic characteristic curve. The apparatus shown for carrying out the process comprises an oscillograph mirror 1 which, in combination with a cylindrical lens 2, forms a fine linear image on a film 3. The image consists of two more or less contrasting halves formed by passing the incident light through a graded light filter 6. This device consists of a disc provided with two concentric zones, 8, 9, or " grey wedges," each of gradually varying density. The gradations are arranged in opposite directions, as shown diagrammatically in Fig. 2, so that, starting from a given transverse line, the density of one zone in one direction increases while that of the other diminishes. The disc 6 is mounted on a spindle 7 carrying a coil 16 located in magnetic field. A microphone 10 is connected to an amplifier 11, the output of which sets up oscillations of the mirror 1, and is so controlled in known manner by a regulating device 15 that the sound frequencies are recorded as transverse displacements of the line L on the film with constant amplitude, irrespective of the variations in volume. Simultaneously the controlling voltages produced by the device 15 are also supplied to the coil 16, and by this means angular displacements of the disc 6 are produced in accordance with the volume variations. These variations are thus recorded as differences in density between the two halves of the record, the contrast increasing with increase of volume. Different sectors of the disc 6 can be covered with grey "wedges" of differing blackening distribution, so as to enable records of different characters to be produced at will. Manual adjustment of the position of the disc 6 can be made as desired, by means of a knob 17, to produce arbitrary changes of the volume record. Specifications 334,354, [Class 40 (ii), Phonographs &c.], and 360,903 are referred to.

Abstract: 1,260,379. Toner concentration sensor. RANK XEROX Ltd. May 21, 1969 [May 24, 1968], No. 26011/69. Headings G2H and G3R. Toner concentration in a two-component developer is monitored in a cascade applicator by means of an optical transmission measurement on conductive transparent plates over which a sample of the developer flows and which are held at a potential so that an amount of toner is attracted thereto dependent on its concentration. A reciprocating gate in the toner dispenser may be automatically controlled to maintain the desired concentration. The cascade applicator Fig. 2 (not shown) comprises upper and lower chambers (245 and 225), bucket conveying means and a toner dispenser (15) having a metering gate (304) reciprocated by a motor (M10). A fraction of the developer falls through a slit (285) to the sensor unit 340. Within the sensor housing is positioned an angled element 345 for splitting the developer into two approximately equal flows which are diverted through 90 degrees by baffle plates 350 and 354 spaced a small distance from adjustable gates 349 and 353 allowing controllable amounts to pass over conductive glass plates 351 and 355 located adjacent a photo-cell P1 and a lamp LMP1 resp. Each of the plates 351 and 355 have a thin conductive layer which is scribed through to produce two electrically separate areas 357 and 358 so that opposite polarities may be applied on each plate. In operation, by means of a timing mechanism comprising a series of cams Figs.8 and 9 (not shown) area 357 is held in an "attract" condition for a predetermined time at the end of which a transmission measurement is made through the two plates while the developer is flowing and then the polarities of areas 357 and 358 are reversed to allow area 357 to be cleaned by the flowing developer. The photo-cell P1 is connected to a threshold detector (379) Fig. 7 (not shown) in the form of a Schmitt trigger which produces a pulse when the resistance of the photo-cell P1 attains a predetermined value, which pulse is fed to a timer-relay (388), connect to motor M10, which is arranged to be "ON" for an adjustable predetermined time when fed with a pulse.

Title: Process for carrying out hydrocarbon reactions accelerated by catalysts of an acid nature
IPC: B01J31/10
Filed: 1953-09-23
Abstract: Polymerization or copolymerization of alkenes and/or alkadienes and alkylation of an alkane, naphthene or aromatic hydrocarbon with an alkene are carried out in the presence of a solid, capillary-active hydrogen exchanging resin gel, which is stable under the reaction conditions, as catalyst.  The reactions may take place in liquid or vapour phase and at elevated temperature and pressure, the upper limit of temperature being between 125 DEG  and 225 DEG  C., depending on the resin gel used.  The catalysts are prepared by precipitating polyvalent phenols with aldehydes, e.g. formaldehyde, and may also contain sulphonic, carboxylic, phosphoric and phosphorous acid groups.  Catalytically-active non-metals such as chlorine and flourine may also be included in the macromolecule. Activity is increased by a small proportion of water or water vapour on or near the surface of the catalyst. Specific reactions mentioned are polymerization and dimerization of isobutene, copolymerization of n-butene and isobutene to a branched octene, and the alkylation of isobutane with propene or butene, and of benzene, naphthalene, anthracene and phenanthrene with higher alkenes or alkene polymers. In examples: (1) isobutane and n-butene were fed at 100 DEG  C. and 5 atm. through a tube filled with hydrogen exchanging resin containing hydroxyl and sulphonic groups to give iso-octane; (2) n-butene and isobutene over the same catalyst at 80 DEG  C. and 3 atm. gave iso-octene; (3) propene at 120 DEG  C. and 11 atm. over a resin containing phenolic hydroxyl and phosphoric groups gave di-, tri- and tetra-mers of propene.ALSO:A solid, capillary active hydrogen-exchanging resin gel is used as catalyst in the polymerization or copolymerization of alkenes and/or alkadienes and alkylation of an alkane, naphthene or aromatic hydrocarbon with an alkene.  The resin gels, which are of the phenolformaldehyde type, may also contain sulphonic, carboxylic, phosphoric and phosphorous acid groups. Catalytically active non-metals such as chlorine and fluorine may also be introduced by ion exchange with previously incorporated anion groups.
