Title: Improvements relating to servomotor systems on vehicles
Inventor: FIALA ERNST
IPC: B60T13/14
Filed: 1963-10-24
Abstract: 1,023,723. Fluid-pressure brakes; clutch control; valves. DAIMLER-BENZ A.G. Oct. 24, 1963, No. 42078/63. Headings F2F, F2L and F2V. [Also in Division F1] A servomotor system on a vehicle, particularly for actuating brakes, clutch or throttle linkage, comprises a control valve 10 with passages 34, 36 and 35 in its housing 19 for connecting the valve to a pressure accumulator 14 via a pipe 15, a pressureless reservoir 16 via a pipe 17 and one or more fluid motors 11 via pipes 13, 13<SP>1</SP>, 13<SP>11</SP> respectively, the housing 19 containing two chambers 27, 28 which can be put in communication with each other by a spring-loaded valve body 33 and of which one is a pressure chamber 27 permanently connected to the accumulator 14 via passage 34, while the other is a working chamber 28, in which the pressure is variable, sealed against the outside by a piston valve 20 which coacts with the valve body and which has a stem 21 extending outside the housing and acted upon through a spring 23 by an element 24 movable by the driver of the vehicle. When the piston valve 20 is urged to the left by the driver, the piston valve is moved against a cut-off element 38 formed on the valve body 33 and to move the valve body 33 in the opening direction against the pressure in the pressure chamber 27 and to close the passage 36 leading to the reservoir 16. Pressure can now be built up in the working chamber 28 through the opened valve body 33 and this pressure is propagated through the pipes 13, 13<SP>1</SP> and 13<SP>11</SP> to actuate the motors 11 and apply the brakes in the brake system illustrated. The pressure in the chamber 28 also acts on the adjacent end face of the piston valve 20 and thus tends to urge the valve to the right against the spring 23. The pressure in the chamber 28 will increase until the force on the piston valve 20 is somewhat greater than the reduced resistance of the spring 23. The piston valve 20 will then move back until the valve body 33 comes to bear against the seating 31. The reduction of pressure in the chamber 28 resulting from the forcing back of the piston valve 20 against the resistance of the spring 23 enables the axial bore 41 to be opened. A condition of equilibrium is established and it is possible for the motors 11 to be actuated under the control of short movements dependent upon the stiffness of the spring 23. When the control valve is not actuated the motors 11 are connected through the working chamber 28 and open axial and radial bores 41 and 42 in the piston valve 20 to the pressureless reservoir 16. The piston valve 20 is retained in its initial position by the spring 43. Instead of the valve body 33 being provided with a cutoff element 38, the piston valve 20 may be supplied with an axial spigot portion which is adapted to lift the valve body 33 off its seat when the pedal lever 25 is depressed (Fig. 3, not shown).

Abstract: Tricyclic saturated hydrocarbons having at least one perhydroaromatic ring and at least 12 carbon atoms are isomerized in the presence of an aluminium halide at -5 to 50 DEG  C.; the reaction proceeds in stages producing eventually a substituted adamantane, the intermediates varying according to the starting material.  The catalyst is preferably a complex of a paraffin having 7 or more carbon atoms and aluminium chloride or bromide with the corresponding hydrogen halide.  Starting materials specified are the fully hydrogenated derivatives of acenaphthene, 2,3- or 4,5-cyclopentaneindane, hydrindacene, fluorene, 1,2- or 2,3-cyclopentanonaphthalene, phenalene, homotetraphthene, anthracene, phenanthrene, indane-1-spirocyclohexane, tetralin - 2 - spirocyclopentane, 1,2;3,4 - dibenzocycloheptatriene - 1,3,5, 2-phenylnaphthalene, and terphenyl.  The following conversions are described and exemplified (1) perhydroacenaphthene to (a) an isomer in which the decalin portion has the trans form, (b) 1-ethyladamantane and (c) 1,3-dimethyladamantane; (2) perhydrofluorene to (a) the trans isomer, (b) perhydrophenalene, (c) 1-ethyl - 3 - methyladamantane, (d) 1,3,5 - trimethyladamantane; (3) perhydrophenanthrene to (a) an equilibrium mixture of iso- and transisomers, (b) trans-syn-trans perhydroanthracene together with trans-anti-trans perhydrophenanthrene and cis-syn-trans perhydroanthracene, (c) 2-methylperhydrophenalene, (d) 1-ethyl - 3,5 - dimethyladamantane and (e) 1,3,5,7 - tetramethyladamantane; (4) 1-methyl perhydroanthracene to (a) the 2-methyl isomer, (b) 2,5 - dimethylperhydrophenalene, (c) diethylmethyladamantane and (d) 1-ethyl-3,5,7-trimethyladamantane. With this latter C15 feed, and more so with higher feeds, some splitting off of isobutane occurs to give in the C15 case methyladamantane. In such cases hydrogen or a hydrogen donor is added, particularly naphthenes which may form decalins in the process, C6 naphthenes forming dimethyldecalins and C7 the tetramethyl compounds.

Title: Improvements relating to the Development of Light-Sensitive Silver Halide Materials
Inventor: WILLEMS JOZEF FRANS
IPC: G03C1/043
Filed: 1965-10-11
Abstract: 1,150,558. Photographic materials. GEVAERT-AGFA N. V. Aug.22, 1966 [Oct. 11, 1965], No.42972/65. Heading G2C. [Also in Division C3] In the development of photographic materials containing a silver halide, the speed and/or graduation is increased by effecting development in the presence of a water-soluble polyester or polyurethane obtainable by reacting or polyhydric alcohol (or corresponding epoxy compound) containing a tertiary amino group with a dicarboxylic acid (or ester-forming derivative) or an organic di-isocyanate. Such polymers are stated to have the formula wherein R is a C 1-5  alkyl group, an aralkyl group or a hydroxyalkyl group; Y is an alkylene chain containing 2 to 10 carbon atoms and which may be hydroxy substituted; A is a chemical bond or the - NH - group; and X represents - CH = CH - or an alkylene chain containing 2 to 10 carbon atoms which may be substituted or interrupted by oxygen, sulphur a - COÀO - group or substituted nitrogen. The polymers may be used in salt form e.g. with sulphuric, hydrochloric, acetic or ptoluene sulphonic acid. They may be added to the coating composition of a silver halide emulsion and/or may be incorporated into a water-permeable layer which is applied under or on top of the emulsion layer. Additional sensitizers such as allylthiourea, sodium thiosulphate and allyl isothiocyanate and foginhibitors, compounds may also be added. In the Examples emulsion containing a ripened silver bromoiodide, gelatine, an optical sensitizer of formula 5-methyl-7-hydroxy-s-triazolo [1, 5-a] pyrimidine, a polyester or polyurethane of the present invention and saponine were applied to a cellulose triacetate support and dried. The exposed film was then developed in an aqueous developer containing monomethyl-p-aminophenol suphate, hydroquinone, sodium sulphite, potassium bromide and either (1) borax and boric acid or (2) sodium carbonate.

Title: Colour Television Receiver Circuit
IPC: H04N11/22
Filed: 1966-09-27
Abstract: 1,162,003. Colour television. GENERAL CORP. 27 Sept., 1966 [1 Oct., 1965]. No. 42986/66. Heading H4F. The Specification describes a colour television system wherein red 43R, Fig. 7, green 44G and blue 45B colour signals stored in a line sequential manner on a recorder are converted into three separate continuous red, green and blue colour signals by repeating each colour signal over three adjacent lines for application to a shadow mask colour display tube. The line sequential output 38 of the recorder is amplified in video amplifier 4 and the sync. signals separated out in 5. A colour burst signal occurring at the beginning of each red colour signal is passed by gate 9, opened by the line sync. pulses, and is converted into a switching pulse by shaper 10 for application to ring counters 11, 12 and 13. The ring counters are also controlled by the line sync. pulses such that counter 11 produces the gating signal 35, counter 12 the gating signal 36 and counter 13 the gating signal 37. The line sequential signal 38 is passed via a buffer amplifier 16 to a gate 19, via a one-line period delay 14 and buffer amplifier 17, to produce signal 39, to gate 20, and via a further one-line period delay 15 and buffer amplifier 18, to produce signal 40, to gate 21. Gating signals 35, 36 and 37 are respectively fed to control gates 19, 20 and 21. It is thus seen that as each red colour signal reaches its gate, the gate is opened and said signal passes through to form part of a continuous red colour signal R. A continuous green colour signal is likewise produced by gates 23/25 fed by respective buffer amplifiers 16/18 and controlled by counters 12, 13, 11 respectively and gates 27/29 produce a continuous blue colour signal when controlled by counters 13, 11, 12 respectively.
