Abstract: 1534795 Cathode ray tubes COMMISSARIAT A L'ENERGIE ATOMIQUE 9 March 1976 [18 March 1975] 9293/76 Heading H1D [Also in Division H4F] In a scintillator camera having a scintillator 2, Fig. 1, and a continuous photocathode area 10, the emitted electrons are focused into a a plurality of beams 22, corresponding to an array of localized areas into which the photocathode area may nationally be divided, and are accelerated on to a surface to provide signals indicative of the impact of the photoelectrons thereon. In Fig. 1 the beams are focused and accelerated by a sequence of aligned grids and plates 12a, 12b, 12c, 12d, 12e, 18, 24, respectively, maintained at successively higher positive potentials, to impact an array of diodes 28 connected to an XY orthogonal conductor array and circuit permitting determination of which diodes have been impacted. The plate 24 collects electrons backscattered from the diodes 28, and hence prevents them entering neighbouring beams. In the embodiment of Fig. 3, the scintillator 2, preceded by a radiation collimator 38 is mounted on the glass bell-housing 42, the free edge 44 of which is hermetically sealed to the base plate by a fusible tin-indium joint 44, the grids 12 (see also Fig. 4, not shown) and plates 18 and 24 being supported on the columns 50. Instead of spaced focusing grids, continuous walled channels may be employed, built up from suitably slotted partitions (Figs. 7a, 7b, 7c, 7e, 7d, not shown). In further embodiments, the array of diodes may be replaced either by a single layer (Fig. 9, not shown) of amorphous or polycrystalline semiconductor having X or Y conductive strips formed on its opposite surfaces, or by a second scintillator having a photomultiplier disposed at each of its four edges (Fig. 10, not shown).

Title: Lift truck control
Inventor: THOMAS HENRY J
IPC: B66F9/20
Filed: 1969-02-21
Abstract: 1,203,404. Masted lift trucks. CLARK EQUIPMENT CO. 21 Feb., 1969 [26 March, 1968], No. 9464/69. Heading B8H. The three-section mast of a lift truck is extendible at two speeds, and is provided with a control system which permits high speed extension only when the mast is extended above a predetermined height. As shown, the mast ram 24 is extended by actuating a pump P 1  alone or pumps P 1 , P 2  together. The return circuit from the ram to the reservoir 18 includes a restrictor 72 which may be by-passed through a valve 78 and line 76 to produce higher speed lowering of the mast. In operation, to extend the mast, the operator closes switches in the electrical control circuit, Fig. 3 (not shown), to actuate the motor of pump P 1 . After a predetermined extension of the mast, a cam closes a switch in the circuit of the motor of pump P 2  whereby, closing of a further switch by the operator causes the pump P 2  to operate, after a time delay, to produce high speed extension of the mast. As the mast approaches within a predetermined distance of its full extension, a cam opens a further switch to de-energize both pump motors. To move the mast to its fully extended position, the operator then closes further switches to complete the circuit of the motor of pump P 1  to produce low-speed extension of the mast. To retract the mast, the operator closes switches in a circuit containing solenoids of valves 74, 78. Initially, valve 74 opens to allow low-speed retraction of the mast and then, after a time delay, valve 78 opens to by-pass the restrictor 72 to allow high-speed retraction of the mast.

Title: Liquid crystal devices
IPC: C09K19/12
Filed: 1974-03-01
Abstract: 1478592 Controlling light DEFENCE SECRETARY OF STATE FOR 28 Feb 1975 [1 March 1974] 9489/74 Heading G2F In a "twist" liquid crystal cell, a layer of naturally optically active liquid crystal material with a natural molecular helical pitch of the order of or greater than twice the thickness of the layer is disposed between electrode substrates, the substrate surface being arranged such that at one surface of the layer the average molecular alignment is parallel to the surface and at the other surface the alignment is tilted. Fig. 2 (d) shows an analogous arrangement for a non-twisted device i.e. the alignments adjacent the surfaces LU and LR appear parallel when viewed along a normal to the surfaces. Rotation of one surface about an angle # # 90 degrees would give a "twist" cell. Due to the initial tilt, all molecules tend to rotate in the same sense when a field is applied across the layer. Use of an optically active material precludes the formation of domains of reverse twist. The substrate surface for inducing parallel alignment is prepared by oblique evaporation of a dielectric material in a direction making an angle of 45-75 degrees relative to the surface normal. The molecules tend to align transversely to the projection of the evaporation direction on the surface. The second substrate surface of unidirectional tilted alignment is prepared (a) as the first substrate surface followed by uni-directional rubbing transversely of the evaporation direction; (b) simple uni-directional rubbing of the surface; or (c) oblique evaporation of a dielectric material at a grazing angle of 0-15 degrees. In (a) and (b) the projection of the molecular alignment direction is parallel to the rubbing direction and in (c) it is parallel to the evaporation direction. The molecular alignment direction at one layer surface is arranged to be at an angle e.g. 90 degrees to that of the other surface. As described, the cell may be disposed between polarizers and the electrodes may be sloped or segmented e.g. in a coincidence addressed matrix.

Title: Brake system for vehicles
IPC: B60T8/18
Filed: 1945-04-16
Abstract: 590,755. Brakes. SOC. ANON. A. CITROEN. April 16, 1945, No. 9492. Convention date, July 18, 1941. [Class 103 (i)] The distribution of braking- effort between the front and rear wheels of a vehicle is controlled by means responsive to variations in the suspension of the vehicle. As shown, the crossshaft 1 is oscillated by movements of the suspension system, and the piston 4, connected by a rod 3 to an arm 2, thereby transmits a variable pressure to the piston 8 in a cylinder 7. The piston 8 carries a pin 15 which engages a slot 14 in a link 13 pivoted to the brake pedal 16, so that a roller 18 is moved along the curved face of a floating- lever 20 to a position depending on the pressure exerted by the piston 4 and the strength of the spring 12. The force exerted on the pedal 16 is transmitted to pistons 23, one of which is connected to the rear brake cylinders 28 and the other to the front brake cylinders 26, the pressures developed by the individual pistons depending on the position assumed by the roller 18 on the curved lever 20. The distribution control may be effected pneumatically, electrically or mechanically.

Filed: 1931-03-30
Abstract: <PICT:0369412/III/1> Oils such as fatty oils or mineral or fatty oils after acid treatment, are neutralized by treatment with magnesium oxide or hydroxide in the presence of water.  Fatty or mineral oils, such as pressure distillates, kerosene, gasoline or lubricating oil, pass from a tank 10 to an agitator 11 in which the oil is treated with sulphuric or hydrochloric acid supplied through a pipe 12. After settling, the treated oil is centrifuged or passed through a filter 14 containing clay or diatomaceous earth.  The filtered oil is drawn off through a pipe 17 and passes upwardly through one of a series of neutralizing tanks 15, 16, containing crushed brucite or calcined magnesite, moistened with water.  A fine mesh screen is mounted in the frustro-conical base of the tank, and a second screen below the oil outlet 19.  The purified oil may be filtered through fuller's earth, clay, or diatomaceous earth.  The treatment may be effected under superatmospheric temperatures and pressures.  The reactivity of the neutralizing agent is restored by injecting steam, hot water, or a suitable solvent through the pipe 23, and the resulting solution of salts and gummy substances is drawn off through a pipe 20. Simultaneously a blast of air or steam, forced through a pipe 22, cleans the upper screen.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of magnesium or manganese carbonate, or calamine, as neutralizing agent.  This subject-matter does not appear in the Specification as accepted.

Patent GB-232265-A (GB)
Title: Improvements in the production of perylene dyes
IPC: C09B3/14
Filed: 1925-04-14
Abstract: By adding oxidizing agents during the condensation of perylene or its oxy or halogen derivatives with benzoic acid or its halides in the presence of aluminium chloride, the nature of the product is altered or the yield is increased; the same effect is also obtained during the heat treatment of the benzoyl products with aluminium chloride. The oxidizing agents mentioned are manganese peroxide, ferric oxide, ferric chloride, copper oxide and potassium nitrate, employed in quantities of up to 100 per cent by weight of the perylene compound treated.  According to the examples (1) dibenzoylperylene is condensed as described in Specification 212,252 by means of aluminium chloride, but in the presence of pyrolusite and gives an increased yield of the product; (2) perylene and benzoylchloride are condensed in the presence of aluminium chloride and pyrolusite, resulting in an increased output; (3) by adding pyrolusite during the condensation of dibenzoyldioxyperylene (Specification 213,889) with aluminium chloride, a product is obtained which is different from that produced in the absence of the pyrolusite in that it dyes cotton green from a green vat; (4) the condensation product of dibromoperylene of m.p. 222-224 DEG  C.  (Specification 232,266) with benzoyl chloride by means of aluminium chloride dyes cotton bluish violet from a blue vat; when pyrolusite is added during the condensation in quantity equal to that of the perylene compound, the product dyes cotton violet blue from a blue vat; the addition of five times the quantity of pyrolusite gives a dyo which colours cotton red from a brownish red vat; (5) chloroperylene of m.p. 280 DEG  C.  (Specification 232,261) condensed with benzoyl chloride by means of aluminium chloride, produces a compound which dyes cotton violet from a blue vat; if pyrolusite be added, dyes are obtained which dye cotton lilac, red, violet or flesh colour, according to the amount of the addition or the period of condensation; (6) the condensation of tetrachloroperylene of m.p. 242 DEG  C.  (Specification 232,266) with benzoyl chloride in the presence of aluminium chloride yields a dye which gives a blue vat and colours cotton blue; the addition of manganese peroxide results in a product which dyes cotton rose from a violet vat. When freshly-precipitated manganese peroxide is used, the amount required is only one-tenth of that when pyrolusite is employed.  The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of nickel sulphate as a suitable oxidizing agent and includes the following examples:-(1) ferric chloride is added during the condensation of perylene and benzoic acid by means of aluminium chloride and favourably affects the yield; (2) the addition of nickel sulphate during the condensation of tetrachloroperylene of m.p. 242 DEG  C. with benzoyl chloride in the presence of aluminium chloride yields a dye which colours cotton violet.  This subject-matter does not appear in the Specification as accepted.
