Filed: 1938-06-20
Abstract: 499,281. Pictures; picture books. TRANSART AKTIEBOLAG. June 20, 1938, No. 18216. Convention date, June 18, 1937. [Classes 11 and 16] Pictorial designs on one or more sheets of transparent material are rendered entirely or partly invisible from the back of the sheets by covering the back of the design on each sheet wholly or in part with an opaque layer of neutral colour, which has the same appearance as the base on which the sheets are mounted, e.g. the inside of a cover containing the sheets. As the sheets are turned over, the back may thus be caused to appear entirely blank, or to exhibit a part only of the design on the face. The blank sides of the sheets may be uppermost, so that a design only appears when the sheets are turned. Designs having coinciding contours may be placed on the inner sides of two adjacent sheets or of a folded double sheet, the designs being covered on the back with an opaque layer. The covering layers may bear inscriptions relating to the designs.

Title: Improvements in adjustable inductances
IPC: H01F21/06
Filed: 1943-11-05
Abstract: 572,426. Adjusting wireless apparatus. ZENITH RADIO CORPORATION. Nov. 5, 1943, No. 18394. Convention date, Sept. 14, 1942. [Class 37] [Also in Groups XXIV and XXXV] A variable inductance for use in radio circuits has a movable core which is connected to a rectilinearly movable driving member by means of an unenclosed helically coiled element which is transversely resilient and longitudinally inextensible. Fig 1 shows the invention applied to the simultaneous endwise adjustment of powdered iron cores 20, 21, 22 of inductances 10, 11 and 12 in a superheterodyne receiver. The cores are connected by members 24, 25, 26 to a yoke 23 movable by a solenoid 13 against the action of a return spring 30. The first position of yoke 23 is determined by a selected one of a set of stops such as 14, 15 which are adjustably mounted in a disc 34 on a shaft 33 which can be rotated by a knob 32 through gearing 40 to bring any desired stop into the operative position. The arrangement is such that on rotating knob 32 to change the stop, a cam 41 closes contacts 42 to energize solenoid 13 so as to move the yoke to the extreme right position. When the knob 32 has moved another stop into the operative position, cam 41 allows contacts 42 to open, and the yoke is moved by spring 30 to engage the selected stop, thus positioning the cores 20, 21, 22 in the desired tuning positions. Cores 20, 21, 22 fit closely in paper guide tubes 51 and so in order to allow for slight lack of parallelism it is necessary for members 24, 25, 26 to be transversely flexible, and they are made of steel wire wound helically with the coils in contact. The wire is made stiff enough so that there is no axial extension during normal working. One end of each of the members 24, 25, 26 is either moulded into the end of a core, or is cemented into an aperture in the core. The other end is adjustably screwed into an insulating grommet fixed to the yoke 23 or to a spring clip 60 which is preferably insulated. A modified form of driving member.Fig. 2 (not shown), for a heavier core has the helix wound on a central wire to which it is fixed at the ends. This prevents extension of the driving member when the solenoid is energized.

Title: Apparatus for withdrawing solid particles from a high-pressure vessel
Inventor: BALENTINE JAMES HAROLD
IPC: B01J3/02
Filed: 1961-05-23
Abstract: 958,414. Transferring solid particles. UNIVERSAL OIL PRODUCTS CO. May 23, 1961, No. 18526/61. Heading B1F. Apparatus for withdrawing solid particles entrained in a liquid or gas from a high pressure vessel 1, said vessel having at least one conduit 19 for withdrawing fluid from the top part of said vessel, having also an unobstructed conduit 5 connecting the bottom of said vessel to the upper part of a hopper 9 positioned below, the bottom of said hopper being connected to the top part of a second larger hopper 12 by a valved conduit 10, a valved discharge conduit 13 being connected to the bottom of said second hopper, and a valved fluid supply conduit 6 being connected to said unobstructed conduit. In a preferred embodiment, a programming device controls the fluid supply valves 7 and 4 to introduce fluid alternately into conduit 6 and a conduit 3 which is connected to conduit 6 and vessel 1. The high pressure vessel 1 is continuously supplied with, or has generated therein, fragile hydrogel spheres. The spheres may be aged therein in oil and subsequently discharged from the apparatus through line 13 and then drained of oil and calcined. After ageing, liquid is supplied to line 3 thus causing passage of aged material via line 5 to hopper 9. Said passage of aged material is aided by providing a line 15 having a restricted cross-section or orifice or needle valve which permits overflow of solids-free oil from hopper 9 by opening valve 14. When hopper 9 is filled valve 4 is closed and 7 opened thus causing an upward flow of fluid via line 5 into vessel 1 hence arresting said solids passage with a corresponding discharge from vessel 1 through line 19. Valve 14 is now closed, valve 11 opened to facilitate emptying of hopper 9 into hopper 12. When accomplished, valves 11 and 7 are closed so that hopper 9 is again filled from vessel 1 with valve 4 open. This is further facilitated by opening lines 15 and 13, which lines when valve 14 is open, facilitate discharge from hopper 12. To avoid excessive rate of flow a restriction 16 is inserted in line 15, in which a valved line 17 for withdrawing fluid from hoppers 12 or 9 is also incorporated. The term hopper includes a mere pipe and a conduit may be an orifice. The valves are motor operated and a programming system is mentioned, wherein the valves are operated, e.g. electrically, pneumatically, or hydraulically.

Title: Polymerization of cis 1,4 polyisoprene
IPC: C08F136/08
Filed: 1959-06-01
Abstract: Isoprene is polymerized in the presence of a catalyst prepared by reacting an aluminium trialkyl and titanium tetrachloride in an inert solvent in such amounts that the atomic ratio of Al/Ti ranges from 0,81 to 2,0/1 and then removing the inert solvent in a sufficient quantity as to remove at least 30% and not more than 75% of the hydrocarbon-soluble reaction product of the alkyl and tetrachloride. Specified alluminium compounds are the trimethyl, tripropyl, triisobutyl, and trioctyl.  The reaction may take place in the absence of a solvent other than that for the catalyst, but it is preferred that a solvent is present. Specified inert solvents are pentane, hexane, heptane and benzene.ALSO:An isoprene polymerization catalyst is prepared by reacting an aluminium trialkyl and titanium tetrachloride in an inert solvent in such amounts that the atomic ratio of Al/Ti ranges from 0.8/1 to 2.0/1 and then removing the inert solvent in such an amount as to remove at least 30% and not more than 75% of the hydrocarbon-soluble reaction product of the trialkyl and tetrachloride.  Specified aluminium compounds are the trimethyl, tripropyl, triisobutyl and trioctyl.  Specified inert solvents are pentane, hexane, heptane and benzene.  In examples, the precipitate formed by interaction of the Al and Ti compounds is removed by centrifuging, the desired proportion of the liquid phase is withdrawn and the precipitate is redispersed in the liquid, the volume of liquid withdrawn being replaced by fresh solvent.

Title: Improvements relating to ruled screen-bases for one plate heliochromy
IPC: G03C7/10
Filed: 1919-07-26
Abstract: 161,995. Smith, J. T. July 26, 1919. Colour photography, screens for. - Consists in processes and apparatus for ruling coloured line screens on celluloid. To prevent the spreading of the colours when ruled, the celluloid is treated with a pounce, which may be of phenol aniline, alcohols, water, nitro-benzene, benzyl acetate, benzaldehyde, fatty acid esters of alcohols, &c. Pounces in powder form such as pumice, French chalk, &c. may be used. The colour is dissolved in a suitable liquid such as aniline, phenol, or an alcohol. The solvent may be similar to the pouncing-liquid, for example, benzyl alcohol, but if necessary a softener such as nitro-benzene may be added to promote the attack of the colours. A preferred form of ruling-pen consists of a piece of parchment, fine wire gauze, &c., which runs skate-fashion on the celluloid, the width of the line being adjusted by setting the blades obliquely to the line. A ruling-machine may be provided in which the celluloid first passes through a pouncing-device, then between soft rollers of conducting material connected to earth to remove any electrification and so to the first set of pens. An electrically heated wire serves to dry the ruled lines before the next set of pens is reached for ruling the second colour lines, and so on. The lines are examined by a microscope which may have an out-of-focus device to check the intensity of colouring, this device causing the coloured lines to coalesce and should give white. The use of this microscope is facilitated by having a transparent bed over which the ruled celluloid passes. The screen finally passes through a device in which surplus colour is cleaned off by means of a weak solution of caustic soda, acid, alcohol, &c. The colours should be ruled so that any overlap which may occur will not give black; for example, the red lines are ruled with a solution of safranine in benzyl alcohol, the blue lines with a similar solution of triphenylpararosaniline hydrochlorate, intergaps being left, narrower than the lines, which are finally ruled in with a solution of acid green in benzyl alcohol. Specification 129,717 is referred to.

Abstract: 483,070. Supply meters. BRITISH THOMSON-HOUSTON CO., Ltd. July 6, 1936, No. 18732. Convention date, July 6, 1935. [Class 37] [Also in Group XVIII] A D.C. electricity meter is connected across a constant voltage supply whereby the parts normally indicating consumption may indicate time, and serve, for example, as the time element in a tariff device. A motor driven meter, an electrolytic or other meter may be used. As shown, a glow discharge device 11 is used as a potential divider to supply a constant voltage across the anode 4 and cathode 5 of an electrolytic meter. The anode 4 is immersed in mercury 3 in chamber 1 and the cathode 5 is immersed in electrolyte 2, for example, or mercury iodide solution, in a graduated tube 6 connected to chamber 1 by a neck 7 normally closed by a needle valve 8 controlled by a solenoid 13, so that the amount of mercury precipitated at the cathode, which collects in the tube 6 is a measure of the time elapsed since closure of valve 8. A meter (not shown) periodically closes a contact 14 after a certain consumption to energize coil 13 thereby opening valve 8 to empty the collected mercury in tube 6 into chamber 1. A further coil 15, excited in series with coil 13 over contact 14, provided that contacts 9, 10, in tube 6 have not been short circuited by the rising mercury, may operate, for example, a counting mechanism, whereby, only consumption occurring at or above a predetermined rate may be counted. A byepass 16 prevents the mercury in tube 6 rising to the cathode 5 in the event of a very low rate of consumption.

Filed: 1972-04-21
Abstract: 1353271 Gas discharge display panels THOMSON-CSF 21 April 1972 [23 April 1971] 18741/72 Heading H1D A supplementary insulating film 10 constituted by a mixture of powder material and a binder is interposed between the apertured matrix plate 1 and a layer of insulating material 3 covering the electrodes 5 of a gas discharge display panel which comprises two crossed arrays of such electrodes with the cross-points in line with the apertures 2 in the plate 1. The powder may be silica or an oxide of a refractory metal, e.g. chrome oxide, and the binder may be an alkali metal silicate, e.g. potassium silicate. The film 10 prevents the matrix plate 1 adhering to the layer 3 due to softening of the glass, of which these components are commonly made, by the high temperatures (400-450 C.) necessary when making the panel, and also permits sufficient movement to prevent cracking due to uneven expansion or contraction. The film 10 may be coloured to improve contrast, e.g. chrome has a dark green colour. The electrodes 5 are deposited on a slab 4 which is bonded at 6 to an otherwise identical slab (not shown) including a pumping and filling tubulation.
