Title: Rotary pumps for liquids
IPC: F04C14/26
Filed: 1964-09-03
Abstract: 1,019,287. Rotary pumps. GENERAL MOTORS CORPORATION. Sept. 3, 1964 [Sept. 27, 1963], No. 36090/64. Heading F1F. In a pump unit comprising a rotary pump of the outwardly-sliding radial vane-type, a rotary valve intermittently connects the high-pressure side of the pump to the low-pressure side to render the output-pressure pulsatory. As shown, the pump comprises a rotor 122 connected to a driving shaft 138 and engaging with a stationary abutment ring 100 between pressure plates 120, 121. A suction chamber 90 for the pump communicates with a reservoir 46 for liquid e.g. oil, through a passage 62 and a bore 146 in a body 10, whereas a delivery chamber 92 for the pump periodically communicates with a port 176 leading to the interior of a rotatable valve-sleeve 160 through a passage 178 when the sleeve is driven by shaft 138 through a shaft 164 and epicyclic reduction gearing 170, 172, 174. Chamber 92 also communicates with an output fitting 48 through a passage 60, a bore 50 and a ported tube 70. The interior of sleeve 160 communicates with reservoir 46 through two ports 159 (Fig. 3, not shown) in a stationary plate 158 adjacent one end of the sleeve, whereby rotation of the sleeve intermittently connects chamber 92 to reservoir 46, and hence chamber 90, so as to render the pressure at fitting 48 pulsatory. When pressure in chamber 92 exceeds a predetermined value, a small quantity of liquid flows from fitting 48 to chamber 90 through a bore 73, a passage 75, a chamber containing a compression spring 66, a filter 76, a bore 74 in a plug 72 lodged in a pressure-relief valve-member 58, a non-return valve 78, a bore 84 in member 58, and a passage 62. The pressure-difference between the ends of member 58 causes this member to be displaced against the action of spring 66 to permit liquid to flow directly from passage 60 to passage 62 through bore 50. Plate 98 is loaded by compression springs 102, 104 (Fig. 3) and liquid pressure in chamber 92; and the vanes on rotor 122 are loaded by pressure communicated from chamber 92 to their radially-innermost sides through recesses 130 in plates 96, 98. Ring 100 has an inner-peripheral surface of substantially elliptical shape to form with rotor 122 two working chambers having diametrally-opposed inlet and outlet ports 118, 120 (Fig. 5, not shown) in plates 96, 98. An alternative embodiment of the pump unit (Figs. 6, 7, 8, not shown) mainly differs from that shown in that the rotary valve 236 is arranged to connect the outlet fitting 298 to the delivery chamber 292 and the suction chamber 288 alternately, and simultaneously connect the reservoir 261 to chamber 292 and chamber 288, alternately.

Abstract: 1,163,121. Smoke detectors. NITTAN CO. Ltd. Aug.16, 1966 [March 30, 1966], No.36662/66. Heading G1N. [Also in Division H1] A smoke detector for a fire alarm system comprises a closed ionisation chamber 5, Fig.2, surrounded by a second ionisation chamber 8 open to the atmosphere through a wire mesh 6. A cupshaped electrode 1, forming part of the walls of the inner chamber, is common to both chambers and carries, on both sides, radio-active sources 2, 3, e.g. of radium. The second electrode of the inner chamber is provided by a disc 9 carried on an insulating support 5', e.g. of acrylic resin. Cylindrical members 7 together with the wire mesh 6 form the second electrode of the outer chamber. The common electrode 1 is connected to the gate electrode of an FET, Fig.3, normally arranged to be non-conducting. In the presence of smoke in the open ionisation chamber the voltage between the gate and source electrodes of the FET increases causing it to conduct. This in turn causes Zener diode D to conduct to trigger an SCR thereby producing a signal in receiver R which is used to energize an alarm. Reference has been directed by the Comptroller to Specification 1, 009, 271.

Title: Improvements in and relating to the transference of heat from solid surfaces to liquids and semi-liquids
IPC: B01D3/08
Filed: 1929-12-03
Abstract: In film evaporators that may be used for concentrating or distilling liquids the film is mechanically treated, for instance by scraping vanes 11e as shown in Fig. 11, at a multiplicity of points to expose clear surfaces and relay other portions of the film on the cleared parts.  The vanes in a row are displaced by the width of a vane from the positions corresponding to vanes in the adjacent row while the spacing distance in a row is a <PICT:0342830/III/1> <PICT:0342830/III/2> <PICT:0342830/III/3> <PICT:0342830/III/4> <PICT:0342830/III/5> multiple of the width of a vane.  The vanes are adapted to accommodate themselves to the heating surface.  As shown in Fig. 1, the film flows down the inside of a steam-jacketed cylinder 5 while relative rotation occurs between the cylinder and radial scrapers on shaft 2.  The liquid is supplied through pipe 15 to a mouthpiece 18 shown in Fig. 3 which feeds a thin ribbon of liquid on the distributer 12a.  Shutters 19 and 20a control the width and thickness of this ribbon.  In Fig. 4 a rotating heated table is shown.  The liquid, supplied through pipe 28, proceeds to the circumference of the table under the influence of scrapers suspended from arms 30 above the table and is collected by scrapers 32.  A fixed table 33 is shown in Fig. 6 with vanes 41 carried on longitudinal bars 39 reciprocated by lever 42.  The bars rest on cams on shaft 48 which have three steps so that the vanes scrape the surface during the first half of a stroke, then, in the second half, they are raised to spread out the liquid they have scraped up and finally, on the return stroke, they are raised still further to clear the liquid film entirely.

Abstract: 1371125 Printing plates; measuring surface roughness ITEK CORP 9 Aug 1972 [23 Aug 1971] 37101/72 Headings G2C and G2J [Also in Division G1] A process of producing an imaged metal plate useful as a printing plate comprises contacting a physically developable image on a grained metallic support with a solution of metal ions until the image formed is a conductive metallic image adherently bonded to the support, the grain of the metallic support (i) being capable of forming a bond with a metallic image and (ii) when tested on an Optical Scanning Roughness Meter as described below, producing a trace having a Peak Height A of between 0À25 and 0À90, at a Position B of between 0À35 and 0À80 and having a psi value C of between 0À40 and 1À0. The metal support carrying the physically developable image may be obtained by the silver salt diffusion process using a grained metal support as described above as the receptor element, or by exposure of a photo-sensitive element having such a grained metal support. Thus a photo-sensitive element may comprise a photo-sensitive layer of less than 2 microns thickness containing a photo-sensitive material capable of producing a physically developable image on exposure, e.g. silver chloride or a photo-conductor such as TiO 2 , ZnO, ZrO 2 , GeO 2 , InO 2 , CdS, ZnS, SnS 2  or CdSe, on a grained aluminium support having a grain as described above. The printing plate is made by exposing the above element to form a physically developable image, contacting the element with a solution of metal ions, e.g. a stabilized physical developer solution containing AgNO 3 , ferrous ammonium sulphate, ferric nitrate, citric acid, acetic acid and surfactants with or without sulphur compounds such as sodium thiosulphate, cysteine, mercaptoacetic acid or mercaptobenzthiazole, until a conductive metal image adherently bonded to the metal support is formed. The Optical Surface Roughness Meter comprises a coherent light source e.g. a laser 1 to pass coherent light through a spatial filter 2, a collimating objective 3 and a beam splitter 4, the light then striking the surface 5 of the rotating sample being tested and being reflected back through the beam splitter and through a transforming objective 8 to focus on a pinhole aperture 9 which has a photo-tube 10 positioned behind it. The output voltage from the photo-tube is amplified and multiplied by the voltage output of a sinusoidal potentiometer linked to the sample rotator 7, and plots of the power spectrum of the reflected coherent light as modulated by the surface irregularities of the sample are recorded on the X-Y recorder.
