Title: Dry shavers
IPC: H02P25/02
Filed: 1973-01-17
Abstract: 1411335 Automatic control of speed GILLETTE CO 11 Dec 1973 [17 Jan 1973] 2350/73 Heading G3R  In a shaver with a motor driven cutter, the motor is controlled to a speed substantially independent of the load on the cutter.  As shown, the motor Rm forms part of a bridge circuit Rm R 1  R3 R4 with a supply U e.g. a battery across one diagonal. The motor is switched on or off by switching transistors TSI to TSIII according to whether the motor speed dependent voltage across diagonal AB of the bridge is below or above a threshold value as determined by the bridge components, to regulate the motor speed to a desired value that is independent of the motor load and supply voltage. Resistor R 1  may be replaced by a fixed voltage supply, and the cutter resiliently mounted in the shaver with the threshold value at a speed dependent upon the resonant frequency of the cutter. The circuit may be modified Figs. 3 and 4 (not shown) so that the threshold value is above or below the desired motor speed.

Title: Improvements in the transmission of code signals for fire alarm and like purposes
IPC: G08B17/00
Filed: 1923-01-26
Abstract: 214,350. Smith, C., and Sutton, G. J. Jan. 26, 1923. Escapements.-A code wheel for operating an electric switch for fire alarm and like purposes is fixed on the same shaft as a driven wheel which is controlled by a specially constructed escapement mechanism that also actuates a bellhammer. In the resting position (not shown) the block 13, which is pivoted at 9 and carries the bell-hammer 11 and a pawl 14, is in such a position that its projection 16 is engaged by, and on the right-hand side of, a block 18 on a hinged or spring bar 17, the pawl 6 being engaged with the toothed wheel 4 while the pawl 14 is disengaged. When therefore the bar 17 is pulled downwards by the operation of the fire alarm, the block 13 actuated by the weight of the hammer 11 turns clockwise, the pawl 14 being guided by the fixed pin 15 into the position shown where it jerks the wheel 4 momentarily counter-clockwise, thereby permitting the pawl 6 to fall about its pivot 7 into the position shown. The wheel 4 being freed by the latter movement, is thereupon driven clockwise by its spring or weight, and through the pawl 14 forces the block 13 to turn counter-clockwise, causing the hammer 11 to strike the bell 12. At the same time the cam 19 acts on a spring 8 fixed to the pawl 6 which is thereby pressed once more into engagement with the wheel. This cycle of operations is repeated so long as the bar 17 is held down.

Title: Method for the synthetic production of higher alcohols
IPC: H04L15/34
Filed: 1926-01-28
Abstract: 247,177. Patart, G. Feb. 7, 1925, [Convention date]. Alcohols; oxygenated organic compounds.- The catalytic interaction of carbon monoxide and hydrogen under pressure is conducted with a view to the production of higher alcohols than methyl alcohol, by separating from the products the methyl alcohol and other low molecularwedght compounds, and introducing them in the vapour state into the circulating mixtureof carbon monoxide and hydrogen or into a similar mixture before it passes into the methyl alcohol synthesiser. Alternatively, the separated products may be passed alone and under pressure through a reaction chamber containing the same or a similar methyl alcohol-forming catalyst. The separated products must in each case be heated to the temperature of the reaction chamber, say by passing them preferably in a continuous manner through a vessel heated to a point slightly above the critical temperature.. The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of mixtures of zinc oxide with potassium oxide, copper oxide, or copper as catalysts for the reaction, and of pressures of 100 to 500 atmospheres; oxygenated organic compounds are also stated to be produced. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to brake apparatus for automobiles or other like brake apparatus
IPC: B60T13/16
Filed: 1923-01-29
Abstract: 214,739. Peters & Co., Ltd., G. D., and Cross, J. W. Jan. 29, 1923. Fluid-pressure.-Relates to apparatus, particularly for automobiles, of the kind in which the brake cylinder or equivalent is in free communication with the discharge side of a pump adapted to circulate liquid past a valve the spring loading of which can be varied to determine the pressure established in the brake cylinder. The invention consists chiefly in the provision of a screw-threaded member which can be turned by a handle for adjusting the spring-loading of the control valve. The pump 2 which may be driven from the engine crank shaft circulates oil or other liquid from a reservoir 1 through a pipe 5. the casing 4 of the driver's control valve 13 and a pipe 6. A pipe 7 leads from the casing 4 to the brake cylinder or as shown the diaphragm chamber 8 the piston or diaphragm rod 9 being connected to a rock shaft 11. A loading spring 14 is interposed between the valve 13 and a screw-threaded member 16 working in the casing 4 and operable by a hand lever 15. By turning the member 16 the load of the spring 14 on the valve 13 and thus the pressure established by the pump in the chamber 8 can be regulated. Means may be provided for limiting the load which can be put upon the valve 13 so as to avoid' skidding of the wheels. Toothed gearing may be interposed between the operating handle of the valve and the member 16 in such a manner that the movement of the handle may be limited to an arc of a circle, indications being provided as to the braking pressure corresponding to various positions of the handle. The gearing may comprise a pinion on the screwed spindle 16, engaged by an arc. shaped rack carried by a vertical hand-lever of the usual kind, or the pinion may be engaged by a straight sliding rack with a handle. To prevent release of the brakes in the event of stoppage of the pump, a non-return valve may be disposed in the lower part of the casing 4 to prevent back flow through the pipe 5. The brakes may be arranged for application by a spring and be held off by the fluid pressure, such an arrangement is particularly suitable for brakes on trailer vehicles as enabling an automatic application of the brakes to be effected by the breakage of a coupling between the vehicles.

Title: Tertiary amine oxides and their use in dyestuff preparations
Inventor: BERRIE ALISTAIR HOWARD
IPC: D06P1/642
Filed: 1957-01-30
Abstract: The invention comprises tertiary amine oxides of the general formula RR1ArN-->O, where R and R1 are alkyl or substituted alkyl radicals which may be the same or different and Ar is a benzene ring substituted by at least one carboxylic or sulphonic acid group.  The amine oxides may be prepared by treating a tertiary amine of the formula RR1ArN with hydrogen peroxide or a compound which yields hydrogen peroxide on treatment with water such as perbenzoic or persulphuric acid. The reaction may be carried out in an aqueous or aqueous organic medium such as aqueous acetone and the amines may be used in the form of a salt of the carboxylic or sulphonic group.  In the examples: (1) the sodium salt of dimethyl aniline 3-carboxylic acid is treated for 5 hours at 70-80 DEG  C. with 10 vol. hydrogen peroxide, the excess peroxide is destroyed with platinum black and the sodium salt of the amine oxide is isolated and worked up to give dimethyl aniline 3-carboxylic acid N-oxide; (2) to (6) describe a similar reaction using the sodium salts of dimethyl aniline 4-sulphonic acid, diethylaniline 4-sulphonic acid, dimethylaniline 4-carboxylic acid, dimethyl aniline 2-carboxylic acid and N-ethyl-N-b -hydroxyethylaniline-4-sulphonic acid.  The compounds may be used in dyestuff preparations containing leuco sulphuric ester derivatives of vat dyestuffs.ALSO:The invention comprises dyestuff preparations containing a leuco sulphuric ester of a vat dyestuff and a tertiary amine oxide of the general formula RR1ArN-->O where R and R1 are alkyl or substituted alkyl groups and Ar is a benzene ring substituted by at least one carboxylic or sulphonic acid group. The vat dyestuff may be of the anthraquinone, indigo or thioindigo series, e.g. 4 : 41 - dimethyl - 6 : 61-dichlorothioindigo, 5 : 51 : 7 : 71 - tetrabromoindigo, 6 - chloro - 4 : 71 - dimethylthioindigo or dibenzpyrenequinone and the amine oxide may be mixed or milled with the dyestuff in the acid form or in the form of an alkali metal salt of the carboxylic or sulphonic group.  The invention also comprises a process for colouring a textile material by applying to the material a print paste containing a dyestuff preparation described above and subsequently steaming the material.  These pastes are said to give brighter and stronger prints in a shorter development time than similar pastes not containing the amine oxide. In Example (7) a dyestuff preparation containing the sodium salt of the acid sulphuric ester of leuco 4 : 41-dimethyl-6 : 61-dichlorothioindigo and the sodium salt of dimethylaniline 4-sulphonic acid-N-oxide, ethylene glycol monoethyl ether and sodium benzyl sulphanilate is dissolved in water and added to a solution of starch tragacanth thickening and sodium dichromate, the paste is applied from a roller printing machine to cotton fabric which is steamed, washed and dried to give a bright level pink print.  Other amine oxides are mentioned which give similar results.
