Title: Improvements in or relating to brakes for vehicles
IPC: B60T13/06
Filed: 1924-05-20
Abstract: 225,504. Renault, L. Nov. 30, 1923, [Convention date]. Actuated or applied by running axle or wheel; hand and foot transmitting mechanism.-In a brake system with a servo-motor operable in either direction of motion of the vehicle, depression of a brake-pedal first causes a direct application of the brake and then actuation of the same brake through the servo-motor. The pedal 4, by means of the lever 5 and link 6, rotates an arm 7 and screw 8 so as to press a plate 14 against a plate 3, which is rotated in the same sense as the vehicle, axle by gearing 2. Cables 16, 16' connected to the pins 15, 15<1> then draw over the lever 17, one of the cables becoming slack according to the direction of rotation, and the rotation of the axis 13 applies the front and rear brakes by means of the rods AV, AR. If the vehicle is stationary the arm 7 forces the screw 8 into the boss of the lever 9 until the plates 14, 3 touch: then the screw carries round the lever 9 and the cable 11 applies the brakes.

Title: Improved manufacture of croton aldehyde
IPC: C07C45/66
Filed: 1927-05-09
Abstract: 270,764. Elektrizitõtswerk Lonza, (Assignees of Luscher, E.). May 8, 1926, [Convention date]. Croton aldehyde; aldol.-Croton aldehyde is obtained by mixing acetaldehyde whilst excluding oxygen with only so much of a dilute aqueous caustic alkali solution that in the neutralization of the product of the reaction by a mineral acid, for example, sulphuric or phosphoric acid, no precipitate is produced, and this mixture containing aldol, acetaldehyde and a little salt is fractionated directly in an atmosphere of nitrogen. The proportion of caustic alkali amounts to only about 1 to 2 hundredths per cent of the weight of acetaldehyde. The distillation may be continuous. To prevent overheating the alkali is added to a mixture of aldol and acetaldehyde. In examples (1) acetaldehyde is mixed with a small percentage of sodium hydroxide solution, the temperature being allowed to rise gradually to 30-35‹ C., at which it is kept for some time. It is then mixed with phosphoric acid and distilled in a circulating atmosphere of nitrogen; (2) acetaldehyde and a small percentage of dilute caustic soda lye is allowed to flow into a mixture of acetaldehyde and aldol, with careful exclusion of oxygen, the temperature being kept between 30-40‹ C. A part of this mixture is mixed with concentrated phosphoric acid and fractionally distilled in an atmosphere of nitrogen, crude aldol being added as aldehyde and water distil off.

The yarn is produced e.g. in a spinning or fancy twisting frame, by passing a spun yarn (or fibrous strand e.g. roving, which becomes such a yarn with (further) twisting) from a feeding mechanism e.g. a double-apron, roller drafting system, perhaps with an added reinforcing strand, to a twisting spindle and feeding an effect yarn thereto at a point between the feeding machanism and the spindle, whilst holding the effect yarn at a tension which causes it to oscillate with respect to the foundation yarn. The foundation and effect yarns may be the same or different in colour and material e.g. both of wool, and/or the former may have a reinforcing core e.g. of nylon multifilament. Two, perhaps differently coloured, effect yarns may be applied to one (coloured) foundation yarn at closely or widely spaced points along the length thereof.

Patent GB-994592-A (GB)
Title: Method and apparatus for the prevention of pumping with axial flow compressors
IPC: F04D27/02
Filed: 1963-04-01
Abstract: 994,592. Axial-flow compressors. BROWN, BOVERI & CO. Ltd. April 1, 1963 [April 3, 1962], No. 12790/63. Heading F1C. [Also in Division G3] Surging in a single-stage or multi-stage axial-flow compressor is prevented or substantially reduced by sensing the magnitude of vibration of at least one guide or moving blade for use as a regulating parameter. Preferably, the magnitude of vibration of more than one blade is sensed and the greatest or greater magnitude is used as a regulating parameter. The magnitude of vibration of stator blades 5 (or rotor blades) of an axial-flow compressor is sensed by means of strain gauges 6 (or gauges which measure the amplitude directly or in terms of the velocity or acceleration of the vibration), the outputs of the gauges being applied through an amplifier 8 to a regulator 7. The amplifier 8 accepts only the output corresponding to the greatest amplitude of vibration at any one time. The regulator 7 acts through a motor 26 to adjust the position of an abutment 23 for a spring 25 acting on a cam 22 in opposition to a bellows 24 which is exposed to the discharge pressure of the compressor. The cam 22 adjusts the force exerted by a spring 20 in opposition to that exerted on a bellows 18 by the pressure difference developed at a flow-measuring device 19. If the flow as sensed by the device 19 falls in relation to the discharge pressure as sensed by the bellows 24, to a value approaching the surge limit, a valve 21 is opened to vent an oil feed 11 downstream of an orifice 12, whereby the oil pressure exerted on a piston 13 drops causing a blow-off valve 15 to open to increase the flow. If, as a result of, for example, contamination of the blading or change of gas inlet temperature, the surge limit changes and approaches the normal working curve of the compressor, surging may occur despite the blow-off regulation. When this occurs, the resultant blade vibration causes the abutment 23 to be adjusted to restore the safety margin. In a modification, the valve 21 and its associated operating gear 18-26 are omitted and the regulator 7 acts directly on a valve which takes the place of the valve 21. Instead of operating a blow-off valve, the blade vibrations may operate an acoustic or visual signal to indicate the necessity for a manual regulation. Where the vibrations to be sensed are those of a rotor blade, the difficulty of leading connecting cables of a vibration gauge out of the rotor may be avoided by arranging that the natural frequency of vibration of the rotor blade coincides with that of a neighbouring stator blade, whereby the latter vibrates in sympathy with the former. The vibrations are then sensed at the stator blade.

Title: Apparatus for producing Short Duration Blasts of High Pressure Gaseous Fluid from the Discharge Outlet of a Valve Connected to a High Pressure Supply Line
IPC: F15B21/12
Filed: 1967-03-20
Abstract: 1,179,433. Valves. HART-CARTER CO. 20 March, 1967 [29 Dec., 1966], No. 12898/67. Heading F2V. [Also in Division G3] The flow of compressed air from an inlet 17, supplied by a source 14, to an outlet 16 is controlled by a main, diaphragm-type valve 10, the outlet being connected to a tube 18 closed at its free end and having intermediate its ends an aperture 20, the flow of air from this aperture being in the form of a shock-wave. Pressure within the inlet line 12 is transmitted via a duct 26 to the upper side of the diaphragm 22, so forcing it to close the passage between the inlet 17, and outlet 16, as well as to a bleed passage 28 the outer end of which is disposed within a pilot valve 30 and terminates in a nozzle 40. A piston-type closure member 42, attached to a pilot diaphragm 32, is forced to seat on the nozzle by a pressurized air jet 56 issuing continuously from a nozzle 48 and acting on the pilot diaphragm. Upon this jet being interrupted (Fig. 2, not shown), as by an element 52, pressure within the passage 28 unseats piston 42 and is relieved to atmosphere via an aperture 46 so permitting the main diaphragm 22 to be unseated and compressed air to flow into the tube 18. Regular interruption of the jet 56 may be effected by an arrangement (Fig. 3, not shown) comprising a cup shaped member (66) having upstanding flanges projecting from its rim. Relative rotation of member (66) and the pilot valve 30 results in the flanges successively interrupting the jet.
