Title: A hydraulic gear pump or gear wheel motor
IPC: F04C2/08
Filed: 1968-06-28
Abstract: 1,213,593. Gear pumps and motors. G. DUSTERLOH FABRIK FUR BERGWERKSBEDARF. G.m.b.H. June 28, 1968 [June 29, 1967], No.31164/68. Heading F1F. In a hydraulic gear pump or motor, described as a pump, comprising a pair of intermeshing gears 2, 3, rotating in bores in a housing 1 having an inlet 4 and an outlet 5, diametral bores 7 extend across each gear from a tooth gap 8 to a diametrically opposite tooth gap 9. The bores are spaced axially along the gears so that all the bores in each gear are sealed from one another. As shown, the bores are associated with alternate tooth gaps. Liquid from the gaps at higher pressure passes through the bores to the gap at lower pressure to equalize the pressure distribution on the bearings and so relieve the bearings of load and permit the pumping of low -flammability liquids having only slight lubricating properties. To compensate for the reaction thrusts of the tooth pressures, the drawing gear on which the tooth pressures relieve the bearing have less bores 7 than the driven gear on which the tooth pressures apply additional bearing loads.

Inventor: UNSWORTH ALFRED KENNETH
IPC: C08J9/00
Filed: 1948-12-02
Abstract: Cellular products are made by mixing polymers or copolymers with "rosin" and optionally a plasticizer, impregnating the mix whilst at a temperature sufficient to render it homogeneous, e.g. 132 DEG  to 170 DEG  C., with an inert gas, e.g. nitrogen, under high pressure, e.g. 4,000 lbs. per square inch, cooling the gas-filled product whilst maintaining the pressure, releasing the pressure, and then expanding the product by reheating it.  The term "rosin" means rosin and similar resins obtained by the distillation of wood, or as a residue from the solvent extraction of rosin and chemically similar products.  Specified resins are polyvinyl chloride, polyvinylidene chloride, polyvinyl acetate, polyvinyl formal, polyvinyl acetal, and copolymers of polyvinyl chloride and polyvinylidene chloride.  The plasticizer may be a butadiene-acrylonitrile copolymer.  The mix may contain stabilizers such as lead or cadmium stearate and a small amount of methylated spirits or colouring agents.

Title: X-ray analysis with a source of beta rays
Inventor: SEIBEL GEORGES
IPC: G01N23/225
Filed: 1960-09-13
Abstract: 960,373. X-ray analysis. COMMISSARIAT A L'ENERGIE ATOMIQUE. Sept. 13,1960 [Sept. 15, 1959], No. 31449/60. Addition to 816,062. Heading G1A. The invention relates to a method and apparatus for X-ray analysis of a sample which uses a radio-active beta-ray source to irradiate the sample and a crystal X-ray spectrograph to measure the intensity of a characteristic line in the X-ray spectrum obtained. As shown the sample S is mounted in a holder 3 which may be driven steadily past the investigation position by a motor Ml if so desired. The apparatus may either be used to measure the thickness of a deposit on the face of the sample or the proportion of a given chemical element present. Irradiation is by means of a layer 33 of Promethium 147 deposited on a metal ring 34 and covered with a thin protective film 35 of polyester resin. The ring 34 has a central channel 4a through which passes X-rays from the sample and retro-diffused beta rays. The latter are diflected by permanent magnet 26 to prevent them reaching the X-ray spectrograph. The X-rays pass through parallel receiving slits 38 to a crystal 36 of lithium fluoride mounted on a plate 37 rotatable about the axis O. Rays diffracted by the reticular parallel planes of the crystal are received by a further set of parallel slits 41 on arm 40 adjustable about axis O and those passing through reach proportional counter 17. The high voltage supply for the counter is indicated at 12 and the pulses generated are passed to amplifiers 13a and 13 and then to a device 14 passing pulses corresponding to rays above a given energy level. These are integrated in rate-meter 15a and fed to a recorder 15b. It is preferred to calibrate the apparatus using standard samples. Where it is necessary to determine the amount of an element of low atomic member present it is necessary to enclose the apparatus in a removable chamber V and to evacuate the chamber by means of a pump P. Other possible radio-active sources are Krypton 85 and Strontium 90 and the permanent magnet 26 could be replaced by an electromagnet. The choice of analysing crystal in the spectrograph will depend on the wavelength of the X-ray line under investigation; mica, gypsum, and quartz crystals can be used. Specification 859,153 also is referred to.

Abstract: 747,338. Driving and withdrawing piles. COMPAGNIE INTERNATIONALE DES PIEUX ARMES FRANKIGNOUL SOC. ANON. Nov, 1, 1954 [Nov. 26, 1953], No. 31545/54. Class 68(2) Pile-driving and withdrawing machinery, or other heavy plant, is mounted on a platform 1 which is so associated with lifting jacks that it can be moved over the ground, for example, for correctly siting a pile 2 to be driven. The platform 1 is formed of longitudinal and cross girders and is supported, when pile-driving is in progress, on assemblies'of girders 3, 4 which are spaced from the platform 1 by screw jacks 5 and bear upon the ground. Lifting jacks 6, 7, 8 are each suspended from a member 9 rotatable in a guide 10 in the platform 1 and supported on conical rollers 12 which engage a flange 11 having a toothed rim which meshes with a pinion 14 driven from adjustment mechanism. The member 9 is rigid with a structure including a plate 15, which' bears on the underside of the platform, and a guide-way 16, 17 for rollers 20 carrying the jack 6, 7 or 8 which has a ball and socket connection 19 with the plate 18. The guides 16, 17 may be oriented; by the revolving member 9 in such a direction that by operation of the jack 21, the platform 1 is moved through a distance limited to the stroke of the jack, the girders 3, 4 being raised from the ground during 'this movement. The weight of the platform is then again taken by the jacks 5 and girders 3, 4, allowing the jack 6 to be retracted along the guides 16, 17 for another movement of the platform 1. If all the guides 16, 17 are oriented in one direction, the platform moves in a straight line when all the jacks 21 are operated, but angular movement of the platform can be produced by arranging one guide 16, 17 at an angle to the other guides.

Title: Improvements in or relating to dividing apparatus
IPC: G01D13/12
Filed: 1946-10-24
Abstract: 618,135. Dividing-engines. BRITISH METAL ENGRAVING CO., Ltd., and HOLLIDAY, E. W. Oct. 24, 1946, No. 31652. [Class 97 (iii)] In a machine for engraving linear scales, a rotatable dividing plate which is mounted to turn with a lead screw and has an angular scale extending continuously through a plurality of complete turns arranged spirally, and an index member which shows the angular position of the plate and which is moved radially relative to the dividing plate by its rotation so that the index member cooperates in succession with the various turns of the scale as the plate is rotated through a succession of revolutions. As shown in Fig. 4, the dividing plate is spirally graduated on its face by a number of radial lines 65 defining the primary divisions and concentric circles 67 defining the secondary divisions. With a lead screw having five threads per inch, two-hundred radial lines are provided and preferably twenty-five or more circles (corresponding to an exact number, e.g. 127, of millimetres). The five outermost tracks, corresponding to one inch, may be coloured in strips, such as 74, 76 spirally arranged to correspond to successive graduations of <1>/64th inch. A scale from 0-127 mms. is suitably marked in a spiral fashion over the twenty-five circles. The index pointer 23 is mounted on a carriage 24 formed by members 37, 38, the carriage sliding radially with respect to the dividing plate 14 on parallel rods 26, 27 and carrying a rack 40 co-operating with a spring-urged pawl 54 mounted on a lever 35. The lever 35 is pivoted at 34 to a plate 33 secured to a bar 32 in which the.parallel rods 26, 27 are mounted. At their lower ends the rods 26, 27 are secured to a block 28 clamped round the collar 13 for the lead screw 12. The carriage 24 has a vertical rod 41 by which it may be raised or lowered, a spring 44 secured to a screw 46 on the plate 33 being provided for frictionally restraining such movement. A second spring 49, secured to the screw 46, urges the lever 35 against its adjustable stop 51. The lever 35 is moved upwards at each complete revolution of the plate 14 by means of a cam projection 57 mounted on the rear surface of the plate which engages a follower 59 mounted on the end of the lever. The follower 59 is spring mounted on the extremity of the lever in such a manner that backward movement (clockwise, as shown) of the plate 14 does not raise the lever 35. On raising the lever 35 upwards the pawl 54 rides over the next adjacent tooth of the rack 40 and when cam 57 has passed the follower 59 the lever, under the action of its restoring spring 49, causes the pawl to urge the rack and the carriage 24 downwards by one step, thus carrying the indicator 68 of the pointer, whose edge 69 is aligned along the radius 66 of the plate 14, down to the next secondary division prior to the commencing of a fresh revolution of the primary scale.

[Class 106 (ii)] [Also in Group VIII] The viscosity or concentration of liquids, particularly concentrations of cellulose pulp is indicated or regulated by imparting rotary movement to the liquid in a vessel 3 open at top and bottom and having a restricted opening in the bottom, variations in the concentration of the liquid causing variations in the velocity and hence in the shape of the surfaces 7, 8, which variations are used for indicating or regulating. The liquid flows upwards through a chamber and out over the top, an opening 6 in the chamber leading tangentially into a vessel 3 coned top and bottom and of cylindrical shape in the middle as shown. An air current is supplied to the vessel by a pipe 10 having a restriction 11, the pipe also communicating with a manometer 12. As the height of the paraboloid 7 changes, the head of liquid over the end 9 of the pipe changes, and also the pressure measured by the manometer 12. If the pipe is extended through the lower paraboloid 8 the same thing happens. The liquid in the vessel 3 may be rotated in other ways than by a constant head and tangential pipe ; a rotating vane is used in one form described. For regulating the supply of diluting liquid, a float may rest on the surface at the apex of the paraboloid 7 and movements thereof may be transmitted by a pivoted lever to a regulating valve.
