Title: Sliding roof closure
IPC: E05B83/00
Filed: 1955-10-04
Abstract: 798,420. Holders for sliding roofs. BAIER O., BAIER, S., BAIER, L., BAIER, W., BAIER, W., and SCHLUMPRECHER. E, [trading as BAIER KOMM-GES WEBASTO-WERK, W.]. Class 44 Relates to sliding roofs for vehicles in which the roof is locked in a desired position by two members which can be forced outwardly against the frame of the vehicle, and consists in providing an actuating handle adapted to lie in a recess in the front bar containing the two members. As shown in Fig. 2, the handle 24 is pulled downwards so that projection 25 enters a notch 26 and on rotation of the handle the projection rides on plate 19 and thus prevents the handle springing back to its retracted position under action of spring 21. Rotation of handle 24 rotates plate 8 to which rods 10, Figs. 1, 2 are pivoted so that rods 10 move inwards; each rod 10 carries a polyamide sleeve 29 moving in a slot in arm 30 so that when the sleeve reaches the end of the slot it withdraws arm 31 from a tube 32 compressing spring 33 and allowing a spring on tube 32 to expand to withdraw brake blocks 40 from the side frames 42 and release the roof for sliding. When handle 24 is reversely rotated, the rods 10 move outwardly and cause brake blocks 40 to engage the sides 42 and hold the sliding roof firmly in position. A member 11 is also rotated by handle 24 to engage a member on the front part of the frame. In a modification, the handle 58, Fig. 4 is pulled downwards against the action of spring 64<SP>1</SP> and on rotation a lip 59 engages under the rim 61, a polyamide pin 62 obviating wear. Rotation of the handle then rotates bridging member 56 to rotate the locking plate 55 carrying the push rods and front locking member. A rubber buffer 64, on the front bar engages a bore 63 on the handle to eliminate noise.

Title: Improvements in or relating to cold-cathode valve circuits
Inventor: GOULDING FREDERICK SYDNEY
IPC: G01R23/09
Filed: 1951-12-03
Abstract: 723,892. Pulse-counting circuits. MULLARD RADIO VALVE CO., Ltd. Nov. 19, 1952 [Dec. 3, 1951], No. 28236/51. Class 37. [Also in Group XL (c)] The Figure shows a pulse-counting or pulserate meter circuit comprising a cold-cathode valve 3 of the type described in Specification 696,077, [Group XL (a)]. Initially a corona discharge exists between trigger 5 and auxiliary cathode 6 so that when a negative input pulse is applied at 17 to the auxiliary cathode the discharge spreads to the main cathode 7 and capacitor 16 is discharged through the trigger/cathode path of the valve. Sufficient ionization is produced by this current flow to cause the main anode/cathode path of the valve to discharge and thus to discharge capacitor 19, the resistor 8 limiting current flow to a value that does not sustain the discharge. Capacitors 16 and 19 are re-charged from the H.T. supply via resistor 14 and resistor 8 and rate-circuit 9 respectively and the rate-circuit 9 indicates on meter 11 the discharge rate through the valve between the anode and main cathode. In a modification, the capacitor 16 is replaced by capacitor 16a between trigger and anode, thus reducing the effective time-constant of the grid circuit. In a further modification a rectifier 20 is included in series with the input circuit to prevent positive pulses being fed back into the input circuit, the input side of the rectifier being connected to a positive potential from the H.T. supply via resistor 21 so that a small current flows through it in the absence of input pulses. Reference has been directed by the Comptroller to Specification 638,833.

Title: Improvements in or relating to containers for powdery or granular materials
Inventor: SHEPHERD DONALD WELTON
IPC: B60P3/22
Filed: 1958-09-03
Abstract: 871,972. Pneumatic conveyers. PORTASILO Ltd. Nov. 12, 1959 [Sept. 3, 1958], No. 28315/58. Class 78 (1). Containers for powdery &c. materials of the type which are emptied by admitting gas under pressure to the interior to fluidize the contents and eject the material through a pipe 16, are provided with an ejector pipe 23 within the container which has an inlet above the normal level of material in the container and an outlet opening into the pipe 16, so that air passes through this pipe to facilitate the discharge of material. The top of the pipe 23 has a bellmouth 24, which is shielded by a downwardlyopening cowling 25, and the inner end of the horizontal part of the pipe 16 is closed by a flapvalve 20. A somewhat similar ejector pipe 27 has its outlet connected to a valve 31 outside the container which is itself connected to a pipe 32 leading to the delivery pipe 26. This valve is adjacent to a valve 17 on the delivery pipes 16, 26. When a blockage occurs in the pipe 26, the valve 17 is closed and the valve 31 opened to admit air to clear the obstruction. The container has a false floor 10 of porous construction below which is a plenum chamber 11 supplied with gas under pressure through a pipe 21. The floor is built up of sectors which are bolted to connecting sealing strips to form a circular floor which slopes downwardly to its centre. A pipe 41 connects the chamber 11 to a pressure-relief valve 33 in the top of the container which opens when the pressure below the floor is less than that above it to prevent collapse of the floor due to the weight of material and the pressure difference.

Title: Process for the production of alkyl aromatic hydrocarbons
IPC: C07C15/107
Filed: 1947-10-24
Abstract: Alkyl aromatic hydrocarbons suitable for detergent manufacture are prepared by contacting a C9 to C18 olefinic charge with sulphuric acid to remove polyolefins and highly-branched olefins, separating it from the acid phase, and using it to alkylate benzene or an alkyl benzene containing not more than 2 alkyl radicals of not more than 2 carbon atoms per radical.  The alkylates are sulphonated and converted to the alkali salts.  Olefinic fractions of thermally cracked petroleum boiling from about 150-300 DEG , preferably 180-225 DEG  C., or polymers of lower olefins, preferably C2 to C4, are treated with 85-100 per cent sulphuric acid, which may be spent acid from an alkylation; preferably at about -20 DEG  to 40 DEG  C., in an amount of about 0.6-7 kgs. per 100 l.  The separated hydrocarbon phase may be water-washed and dried, and is used in a molar ratio of, for example, 2-30 : 1 of the aromatic hydrocarbon, in an alkylation reaction with such catalysts as 80-100 per cent or stronger sulphuric acid, hydrogen fluoride containing not more than 10 per cent of water, aluminium chloride or bromide, boron fluoride, sulphonic acids, phosphoric acids and hydrogen chloride. With hydrogen fluoride, temperature is about -30 DEG  to 100 DEG  C., and pressure sufficient to maintain the liquid phase.  The desired alkylate is separated from the product by fractionation.  In examples, a fraction boiling at 170-220 DEG  C., containing C9 to C15 olefins from a cracked gas oil fraction is used to alkylate toluene with hydrogen fluoride without pretreatment, or after treatment with 95 per cent sulphuric acid, to yield a 275-345 DEG  C. alkylate for detergent manufacture.  The Specification as open to inspection under Sect. 91 comprises the alkylation of other aromatic hydrocarbons such as tri- or tetraalkyl benzenes, e.g. mesitylene and 1,2,3-trimethylbenzene, and polycylic aromatic hydrocarbons, e.g. naphthalene and alkyl naphthalenes.  This subject-matter does not appear in the Specification as accepted.

IPC: C10G1/06
Filed: 1927-10-31
Abstract: 281,240. Bates, L. T. Nov. 23, 1926, [Convention date]. Liquid fuel is obtained by the intensive attrition of coal in a liquid hydrocarbon in presence of hydrogen. Liquid hydrocarbons specified as suitable are coal oils, mineral oils, liquid derivatives of coal such as solvent naphtha tar or creosote, and the liquid product of the process. A metallic or gaseous catalyst may be passed into the mill or the fuel ingredients may contact with a catalyst during the process. In an example, powdered coal from a pipe 2 and oil or tar from a pipe 3 are conveyed through pipes 1, 4 to an insulated or steam-jacketed disc mill, hammer mill. or other fine grinding apparatus 5 rotating at 1000 revs. per minute, and hydrogen or watergas is pumped in through a heater 7. Gases and vapours may be drawn off through a filter 8 by a pump 9. The liquid fuel is withdrawn through a pipe 10 to storage tanks, separators, or cracking stills. The process may be made continuous by use of a series of mills, the hydrogen may be heated or cold or under pressure up to 10 lb. and the temperature may be regulated by the speed and frictional resistance of the mill, the volatiles being thus rejected or retained during the operation. The fuel may be used as fuel oil or in semi-Diesel or hot bulb engines.
