Title: Improvements in and relating to vulcanised or sulphurised oil compositions and to products or articles of manufacture produced with the aid thereof
Filed: 1943-03-30
Abstract: Sulphurized oil compositions are made by compounding gelled fatty oils, other vulcanized oils, fillers, pigments or fibres with a fatty oil reacted with sulphur chloride in the presence of a volatile organic solvent functioning as a diluent to produce highly viscous liquid products which are still soluble in cyclic hydrocarbons and are subsequently cured and rendered insoluble therein by the addition of a curing substance, such as zinc, magnesium, or calcium oxide, carbon black or colloidal silica, or by heating with or without pressure, or by both means.  The curing may be effected in situ.  The fatty oil and solvent specified comprise castor oil and benzol respectively.  The free acid produced during the sulphurizing treatment is removed or neutralized such as by basic materials which function as curing agents.  The products may be used as coating compositions for stone, as a material for making moulded articles, and as a rubber reducer.

Abstract: 1,097,621. Fluid-pressure brakes; hydrodynamic brakes. H. TEVES, E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINEN - UND ARMATURENFABRIK KOMM. GES.]. Feb. 5, 1965 [March 18, 1964], No. 5114/65. Headings F2E and F2F. A motor vehicle braking system comprises a friction brake system 40, 41 for the vehicle wheels operated by a tandem master cylinder 1 and an hydrodynamic retarder 32 which operates on a shaft 48 of the vehicle drive, the operation of the hydrodynamic retarder and the wheel brake system being controlled in dependence upon the pressure difference in the hydrodynamic retarder wherein the pressure in the brake circuits of the friction brake system is controlled by a diaphragm valve 8 whose diaphragm 9 experiences the pressure difference in the hydrodynamic retarder. The diaphragm 9 subdivides the diaphragm valve 8 into two component casings 10, 11 which are connected the one (11) to the high pressure side through lines 43 and 42 and the other (10) to the low-pressure side of the hydrodynamic retarder 32 via return line 46 from a cooler 45 and the line 47. Connected to the diaphragm 9 are valve rods 15, 20, each co-operating with a piston valve 17, 22 respectively, the piston valve controlling the supply of pressure medium from one working chamber 2 of the tandem master cylinder 1 to the wheel brakes 40 of one brake circuit through a brake booster 28 and to the valve member 30 of a valve for operating the hydrodynamic retarder from a reservoir 31. The piston valves 17, 22 also control the supply of pressure medium from the other working chamber 3 of the tandem master cylinder 1 to the wheel brakes 41 of the other brake circuit through a brake booster 36. When the master cylinder 1 is operated the brakes 40 and 41 and the hydrodynamic retarder 32 are all operated simultaneously and as the speed of the shaft 48 of the hydrodynamic retarder 32 progressively decreases the effect of the retarder is reduced and the difference between the pressures in the casings 10, 11 of the valve 8 is similarly diminished, the brakes 40, 41 becoming fully operative while the retarder becomes inoperative. Reference has been directed by the Comptroller to Specification 1,027,556.
Patent GB-450210-A (GB)
Title: Improvements in or relating to the recovery of iodine from seaweed
IPC: C01B7/16
Filed: 1935-01-11
Abstract: Iodine or iodine compounds are recovered from seaweed by extraction of the seaweed to obtain an aqueous solution of soluble iodine salt which is then treated with a soluble copper salt, preferably sulphate, in the presence of an acid, e.g. sulphuric or hydrochloric acid, and of a metal, preferably copper, acting as an antioxidizing agent.  The seaweed is extracted with a dilute solution of an alkaline earth salt, e.g. calcium or barium chlorides, which dissolves laminerine and iodine containing material, leaving the algulose and algin undissolved, preferably in the cold state. Subsequent washing with soft water removes the excess alkaline earth salt and the remaining iodine &c. Impurities are then removed from the extract by treatment with a 15 per cent aqueous solution of sodium carbonate.  The precipitate of alkaline-earth carbonate carries down the impurities.  The precipitate is washed thoroughly and the wash waters added to the mother liquor containing iodine. This liquor is then treated as above to obtain a precipitate of cuprous iodide.  Copper is recovered from the liquor remaining after separation of the precipitate by treatment with iron, and the other salts present may be separated by fractional crystallization.  Iodine may be recovered from the cuprous iodide by calcination with caustic soda or potash with the addition of a substantially equal weight of sodium nitrate at a temperature of 350 DEG --375 DEG  C. followed, for example, by treatment with chlorine, or recovery of iodine by other known methods.  Alternatively, barium iodide may be obtained by treating the cuprous iodide with baryta water at 90 DEG --100 DEG C., and metal iodides may be obtained therefrom by treatment with sulphates, e.g. sodium sulphate.  Specification 450,358 is referred to.

Title: Improvements in clutch control apparatus
IPC: B60K23/02
Filed: 1932-02-24
Abstract: 388,569. Controlling motor vehicles. ROCHE, C. R., 211, South Detroit Street, Los Angeles, U.S.A. Feb. 24, 1932, No. 5518. Convention date, Feb. 24, 1931. [Class 79 (v).] In clutch-controlling apparatus for automobiles of the kind comprising a pneumatic cylinder 24, Figs. 1 and 4, the piston 31 of which is connected to the clutch 8, and a valve 12 operable automatically according to the degree of vacuum in the intake manifold 3 to place the cylinder in communication with the atmosphere or the intake manifold, air is transferred from one side of the piston 31 to the other in the clutch-engaging stroke by way of the valve 12. The valve 12 has a piston-valve member 14 one end of which communicates with the manifold 3 by a channel 19 and a pipe 13. When the throttle valve 5 is closed by release of the accelerator 40 the vacuum in the manifold 3 allows the valve 14 to be moved under atmospheric pressure in the chamber 18 against the action of a spring 15 so that its neck 21 is opposite the ends of pipes 13, 23, whereby the manifold 3 and the chamber 30 of the pneumatic cylinder 24 are put in communication. The vacuum created in the chamber 30 allows air entering the other chamber 32 to move the piston 31 to the end 37 thus causing a lever 35 to rock the clutch shaft 9 in the same manner as the clutch pedal 10. The opening movement of the clutch is retarded by a resilient block 36, Fig. 4. To prevent the clutch engagement being too violent, in the first part of the return movement of the piston 31, air passes freely from the chamber 32 to the chamber 30 past a port 48 controlled by a piston valve 45 moving with the piston 31, and in the second part, the port 48 is closed and air passes from the chamber 32 by way of a port 49 controlled by a needle valve 50 and communicating with the casing 46 of the valve 45, and so to the chamber 30. Communication between the chambers 30 and the casing 46 is established by tubes 53, 23 leading to ports 52, 51 controlled by the valve 14. To stop the automatic operation of the clutch and allow operation by the pedal 10, the manifold is isolated by the valve 14, which is moved to the right in Fig. 2 by the control 61, Fig. 1, the operating cable 57 of which has a lost motion connection with the valve 14. The chamber 32 has an air filter 66, and a flexible sleeve 69 protects the protruding part of the piston-rod.

Abstract: 785,879. Electric digital-data-storage apparatus. STANDARD TELEPHONES & CABLES, Ltd. Feb. 25, 1954, No. 5537/54. Class 106 (1). In a data storage device comprising read-in and read-out means, a source of clock pulses and means under the control of said clock pulses for determining the instant at which data is to be read in, means operated by said clock pulses are provided for generating a number of control pulses within the width of a single clock pulse and for selectively applying one of said control pulses to gating means connected to said readout means whereby a selected portion only of a signal read by said read-out means passes through said gating means. As a result of an input of one clock pulse derived from a magnetic drum 2, Fig. 1, by a head 9 and a pulse shaper 11, a device 12 provides seven successive output pulses, one at each of seven terminals F1, F2 ... F7, each output pulse having a duration of <SP>1</SP>/ 7 th of the duration of the clock pulse, and consists of seven conventional hard valve monostable flip-flops (Fig. 3, not shown) P1, P2 ... P7, Fig. 2, in series with " <SP>1</SP>/ 7 th " inductorcapacitor delays (Fig. 4, not shown) D1, D2 ... D6. Certain of the sub-cock pulse trains from the device 12, Fig. 1, selected by trial and error, are used to control reading out gates 19, 20, 21, thus obviating the necessity of a fine mechanical adjustment for each reading head. Specification 744,352 is referred to.

Abstract: 1,178,675. Television camera circuits. ELECTRICAL & MUSICAL INSTRUMENTS Ltd. 9 Feb., 1967 [9 Feb., 1966], No. 5570/66. Heading H4F. In a T.V. camera tube 1, Fig. 1, e.g. of the vidicon type, wherein a mask 5 is positioned in front of the target 2 to cast a shadow thereon, thereby defining a reference block level for block level clamping purposes, the edges of said shadow, due to the thickness of the face plate 4 may be ill-defined whereby a partly shaded section of the target is produced bounded on the one hand from a full shadow or true black region by boundary 9, and on the other hand from the clear picture area 7, Fig. 2, by a boundary 8. If black level clamping is carried out whilst scanning the partly shaded section, the clamping level will be incorrect. Accordingly the field scan current 32, Fig. 3, comprises a normal sawtooth with the addition at the top of the field 31 of an over-scan pulse 30 of three line duration. The line scan thus proceeds at normal speed up the frame, until it approaches the partly shaded section. Then, the addition of the over-scan pulse causes the line scan to move almost instantaneously through said section, and said normal scan to be resumed in the last three lines of the scan, well into the true black region-the field clamping taking place in the middle sections of the last two of said three lines.
