Title: Improvements in clutch control mechanism
IPC: B60K23/02
Filed: 1935-01-04
Abstract: 455,026. Operating clutches. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. Jan. 4, 1935, No. 348. Void [Abridged as open to inspection under Sect. 91 of the Acts, July 6, 1935]. [Class 80 (ii)] In a clutch-control mechanism for a motor vehicle, a power actuator, insufficient in itself to disengage the clutch, assists the operator in disengaging the clutch but completely controls the clutch engagement. A clutch 10, 12 with spring 14 is adapted to be operated jointly by the usual pedal 16 and a pressure-differential motor 18. The clutch pedal is connected by a link 22 to a tubular member 26 which in turn is connected to a piston 20 in an openended fixed cylinder 28. Conduits 31, 30 connect the intake manifold 32 of the engine remote from the throttle 36 with a port 38 in the tube 26, and a conduit 40 with check valve 42 connects conduit 31 with the closed end of cylinder 28. A poppet valve 48 with stem 50 attached to a piston 52 is loaded by a spring 58 which is stronger than a spring 56 behind piston 52. The relative strengths of clutch springs 14 and springs 56, 58 are such that the valve 48 is unseated to open up connection between the manifold and cylinder 28 just as the clutch elements are about to be disengaged. The piston 52 is ported at 60 to permit air to circulate freely between both sides of the piston, and the piston 20 has vents 62 to permit entry of air to cushion the engagement of the clutch. With the throttle 36 closed, the pedal 16 is depressed and valve 48 unseated just as the clutch plates are at disengaging pcint. The manifold vacuum is transmitted to cylinder 28 and the resulting load on piston 20 is added to the effort of the operator on the clutch pedal. There is no follow-up action. To engage the clutch, the pedal 16 is released and the clutch springs function. Air is drawn into the cylinder at a rate depending on throttle opening and the size and shape of conduit 30, valve 48, ports 62, &c. The clutch is thus engaged relatively rapidly, but this rapid movement is terminated when the load on spring 58 is reduced sufficiently to cause valve 48 to be seated, this occurring just as the members are about to engage. Thereafter the rate of engagement is solely a function of the rate of ingress of air by way of ports 62. In a modification, a ported flexible diaphragm is connected to the tube 26 and is clamped between closed sections of a casing. The device functions as above, except that the rate of clutch engagement is at all times a function of the degree of throttle opening.

Abstract: 508,956. Speed governors. MOUNTBATTEN, LORD L. Jan. 6, 1938, Nos. 388, 389 and 27104. [Class 57] [Also in Groups XXXVIII and XIX] In a system for maintaining a warship in a fixed position relatively to another ship, an instrument is provided which determines the co-ordinates in the direction of the course being steered, and at right angles thereto of the ship's displacement from its correct position with respect to the other ship and is associated with means for transmitting the values of the coordinates for effecting a controlled variation of the ship's speed and/or course. Fig. 1 shows the system, the equipment enclosed within the zones I ... IV indicated by the dotted lines being mounted in the after superstructure so as to be visible to a following ship, the bridge, wheel house and engine room respectively. The port and starboard engine shafts 1, 2 are coupled through a differential 3 to a shaft 4 which rotates at a speed proportional to the ship's speed, and controls one element of a differential 5. The differential 5 is also controlled by a shaft 6 driven by a constant speed motor 7 through a variable speed gear 8, 10 which is set in a position corresponding to the correct speed of the ship by the standard engine revolution telegraph 11a. The differential 5 controls a step-by-step transmitter 14 connected to a receiver 16, the arrangement being such that the receiver 16 occupies a zero position and the transmitter remains inoperative when the ship is travelling at the correct speed. If the ship lags or leads its correct position, the receiver is deflected and the engines are controlled manually or automatically to bring the receiver back to zero and the ship into its correct station. In order to correct the inevitable slight wandering of the ship from its course due, say, to fluctuations of the speed of the motor 7 and the lack of proportionality between the ship's speed and the engine speed, a correction system incorporating a bearing indicator is employed.

Abstract: 889,642. Brightening polyacrylonitrile fibres. CIBA Ltd. Jan. 5, 1959 [Feb. 17, 1958], No. 410/59. Class 15 (2). Polyacrylonitrile fibres are brightened with brightening agents capable of imparting a brightening effect by the exhaustion method, i.e. by treatment of the fibres in a bath having a goods to liquor ratio between 1 : 10 and 1 : 40 at 60‹C.-100‹C. for a period of at least 15 minutes, by impregnating them with an aqueous preparation containing the brightening agent for a time not sufficient for fixation of the brightening agent to the fibres by exhaustion, and then subjecting them for 1-10 minutes in an aqueous medium to the action of heat or for 1-10 minutes in the moist state to a steaming treatment, at least the second step of the process being carried out in an acid to neutral medium. Specified brightening agents are 4-acyl-aminonaphthalene-1 : 8-dicarboxylic acid amides, pyrazoline-sulphonamides, dibenzimidazyl-ethylene, dibenzimidazyl-furane and dibenzimidazylpyrrole. Suitable acids are sulphuric, oxalic, acetic and formic acids, preferably in a proportion of 0.5%-5% based on the weight of the fibre. The after-treatment in the aqueous medium or with steam may be carried out at 95‹C.-102‹C. The impregnating liquor preferably contains 0.1-5 grams of brightening agent per litre. The treatment may be combined with other improving treatments, e.g. to give a soft feel or anti-static finish. The polyacrylonitrile fibres may be in the form of hanks or woven or knitted fabrics and may be mixed with other fibres, e.g. viscose rayon, or may consist of a copolymer of acrylonitrile with another polymerisable compound.
