Title: Speed control for spinning or twisting machines
Inventor: LONG JOHN RUSSELL
IPC: D01H1/30
Filed: 1957-07-02
Abstract: 845,724. Spinning yarns. SHUFORD MILLS Inc. July 2, 1957, No. 20841/57. Class 120(2). [Also in Group XXIV] A spinning or twisting machine comprises at least one spindle, a ring rail, at least one pair of pulleys having an endless belt trained therearound and mounted one on a main shaft adapted to rotate said spindle and to reciprocate said ring rail and the other on a drive shaft spaced from said main shaft, one of said pulleys being fixed and the other being expansible by fluid pressure to increase its effective diameter, a conduit extending from a source of fluid pressure to said expansible pulley add having a pressure regulator valve interposed therein, and means for progressively opening said valve correspondingly to increase the amount of pressure directed into the expansible pulley with movement of said ring rail in one direction only with each reciprocation thereof, thereby correspondingly to increase the speed of the machine. An electric motor 30 is fixed on a plate 37 slidable horizontally under the influence of a tension spring. On the output shaft 32 is a variable speed pulley assembly 31 the diameter of the pulley being adjusted hydraulically in accordance with the vertical movements of the ring rail 14, to increase the speed of winding as the diameter of yarn wound on the package increases. The ring rail 14 is reciprocated by a lever 21 attached to an oscillating cross arm 20 to which is also attached a crank arm 97 which reciprocates a link 95 to advance a ratchet pawl 93 on a ratchet wheel 90 with each vertical movement of the ring rail 14. The wheel 90 through a spring 91 adjusts a valve 83 to increase the pressure in a conduit 82 and move a movable flange 61 of the pulley assembly 31 towards a fixed flange 57 and thus increase the effective diameter of the pulley. At the end of the winding cycle the pawl 93 is raised and the wheel 90 starts to return the valve 83 to the zero position, and the spring moves the motor 30 to cause the belt 67 to move the flanges 61, 57 apart. Specifications 845,722 and 845,725 are referred to.
Patent GB-378872-A (GB)
Title: Improvements in means for controlling free-wheel devices for motor vehicles
IPC: B60K17/26
Filed: 1931-05-11
Abstract: 378,872. Controlling motor vehicles. GILLETT, E. H. J. C., 51, Priory Road, West Hampstead, London. May 11, 1931, No..20900/32. Divided on 378,857, [Group XXIV]. [Class 79 (v).] Locking means for a free-wheel device arranged in the transmission system independently of the main friction clutch, is controlled by one of the speed-controlling members, i.e. brake or accelerator, in such a manner that on positively operating the said controlling member to perform its usual function the free-wheel device is locked and remains positively locked as long as the controlling member is not in its fully released position. In the construction shown in Fig. 1 a free-wheel clutch arranged in a casing 13 at the rear of the gear-box 11b can be locked by means of a shaft 16 rocked by a link 18, bell crank 19 and cam 21. The cam is fixed on the shaft of a brake pedal 23, and its action is such that on the initial movement of the pedal a roller 20 on the bell crank 19 rides up the face 21a of the cam and locks the free-wheel, a lost-motion device being embodied in the brake gear so that the brake is not yet applied. Further movement of the brake pedal applies the brakes, but the roller 20 and the locking device are not affected thereby as the roller then rides on a circular part 21c of the cam. The pedal 23 may operate the throttle instead of the brake. The handbrake lever, when one is provided, may be independent of the free-wheel locking device.

Title: Antilock control system for four-wheeled vehicles
IPC: B60T8/1764
Filed: 1975-05-16
Abstract: 1500056 Antiskid brake control systems TELDIX GmbH 16 May 1975 [17 May 1974] 20947/75 Heading F2F An antilock control system for four wheeled vehicles in which signals related to wheel speed or deceleration, steering angle and/or vehicle transverse acceleration for two diagonally opposite wheels 1 and 4 are fed to an evaluation circuit 13 to produce signals for transmission to a control unit 10 to regulate brake pressure at wheels 1 and 4, circuit 13 also operating a blocking valve 14 to cut off supply to the brake line of the rear wheel which is not one of the diagonally opposite wheels. Evaluation circuit (Fig. 2).-Sensors 6a and 4a for wheel speed are connected to terminals 20 and 21, change-over switch 22 alternately connecting terminals 20 and 22 into the circuit which further comprises converter 23, signal processing unit 24 and logic unit 25. Acceleration and deceleration valves (-b, + b 1 and b 2 ) are computed in unit 24 by differentiation of the incoming speed signals, and ship signals are derived by means of store 24b and comparators 24c, all signals from unit 24 being fed to logic unit 25 for control of valve 10. A steering angle signal is fed in at terminal 30, a comparator 31 emitting an output signal when the actual steering angle exceeds a preset value. A vehicle speed signal from store 24b is fed to a comparator 32 which emits an output signal characteristic of a range within which the speed signal falls, the outputs from comparators 31 and 32 being fed to AND-gates 33 and OR-gate 34 such that the OR-gate 34 gives an output if a certain steering angle is exceeded for a given speed range which may then cause a brake pressure reduction either by being fed into unit 24 or according to the state of bi-stable 27, also dependent on the input signal to valve 10, controlling a blocking valve 14 in the brake line to rear wheel 3. In a second embodiment a signal representing transverse acceleration may be used instead of, or in addition to, the steering angle signal to control valve 10.

Title: Discharge of cohesive particulate materials
IPC: B65D88/72
Filed: 1977-05-19
Abstract: In order to be able to unload the powdery product (5), for example whole-milk powder, from a silo (4) through an unloading aperture connected to an outlet pipe (8) and arranged in a filter-like plate (6), the product (5) is aerated through the plate (6) and, at the same time, the plate (6) is made to vibrate vertically by a vibrator (26). In this case, it is important that the aerating and the vibration regions are spatially not or hardly separated from one another, and that the joint action of the aeration and the vibrations extends up to the unloading aperture. Such a method makes it possible to cause adherent powdery products to flow continuously, it being possible for the outflowing quantity to be influenced by the quantity of air supplied. <IMAGE>

Title: Method of producing a composite synthetic resin and product thereof
IPC: C08G14/06
Filed: 1947-08-06
Abstract: A composite two-stage resin is produced by condensing a resin-forming primary aryl amine or a secondary di-aryl amine with an aldehyde and forming a thermoplastic aromatic amine-aldehyde resin constituting 5 to 8 per cent of the composite resin, mixing therewith a solution of unreacted aldehyde and unreacted polyhydroxy benzene, a derivative, or a substitution product thereof, the molar ratio of aldehyde to polyhydroxy benzene, homologue, or derivative being less than 1 : 1, and reacting the solution by heating in the presence of the pre-condensed aromatic amine-aldehyde resin.  The products are suitable as moulding materials, adhesives for laminates of wood, cloth, leather, natural or synthetic rubber, asbestos or glass fibres.  Other fillers include wood flour, dye, calcium carbonate, kieselguhr or cellulose.  Specified are aldehydes: formaldehyde, acetaldehyde, paraldehyde, propionaldehyde, butyraldehyde, furfuraldehyde, glyoxal; polyhydroxy benzenes: resorcinol, alkyl resorcinols, ethers including monomethyl resorcyl ether, esters including resorcinol disulphonic acid esters, pyrogallol, phloroglucinol and their homologues.  Hardening agents include hexamethylene tetramine or methylol compounds such as dimethylol para cresol, polymethylol phenols or their salts, methylol resorcinol, methylol xylenols, dimethylol urea, dimethylol thiourea and methylol melamine.  A suitable polymethylol phenol is prepared by reacting phenol and formaldehyde with an NaOH catalyst at 20 DEG  to 25 DEG C.  In examples: (1) ortho amino diphenyl and formaldehyde are reacted until combination is complete and a solution of resorcinol in formalin is then added and the mixture refluxed; (2) the general procedure of (1) is followed using aniline in place of the ortho amino diphenyl; (3) a solution of diphenylamine replaces the aniline of (2).  The low curing temperature of the products makes them suitable for forming large laminated articles, e.g. furniture, sections of aeroplanes and hulls of dinghys.  The Specification as open to inspection under Sect. 91 comprises also the preparation of one stage resins by employing a ratio of aldehyde to dihydroxy benzene of more than 1 : 1, preferably 1 : 1 to 2 : 1.  The use of tertiary amines and the reaction of an aromatic amine with an aldehyde in the presence of a partially or completely condensed polyhydroxy benzene-aldehyde reaction mixture are also referred to. This subject-matter does not appear in the Specification as accepted.
