Title: Improvements in or relating to clutches
IPC: F16D43/12
Filed: 1935-08-09
Abstract: 456,925. Friction clutches. BORGWARNER CORPORATION, 310, South Michigan Avenue, Chicago, U.S.A.-(Assignees of Wemp, E. E. ; 746, Collingwood Avenue, Detroit, Michigan, U.S.A.) Aug. 9, 1935, Nos. 22465 and 22466. Convention dates, Aug. 10, 1934 and Aug. 2, 1935. [Class 80 (ii)] The radial disengaging levers 20 of the plate clutch of a motor vehicle, which act on the presser plate 15 and are fulcrumed on the cover plate 3 secured to the engine flywheel 2, have weighted outer ends 24 so arranged that, upon increase of engine speed, centrifugal action augments the pressure of the engaging springs 16 on the plate 15, these springs being of such a strength that the torque capacity of the clutch due solely thereto is slightly in excess of the maximum engine torque. The additional torque capacity due to the centrifugal action corresponds to that transmitted to the clutch due to dissipation of kinetic energy upon a reduction in speed. Each lever 20 is pivotally connected to a bifurcated driving lug 17 of the plate 15 through a needle roller bearing 22, and has an aperture 32 which receives both a pin 33 fixed in a bifurcated bracket 30 secured to the cover plate 3 and a loose roller 35 bearing against a flat side 34 of the pin 33. The clutch withdrawal sleeve 9 co-operates with screws 37 adjustably mounted in the inner ends of the levers.

Title: Method and means for forming a tufted fabric having different heights of tufting thereon
IPC: D05C15/00
Filed: 1959-06-30
Abstract: 868,174. Sewing machines. MUSHLIAN, H. R. (Russel-Lacey Mfg Co. Inc.) June 30, 1959, No. 22488/59. Class 112 The invention relates to a method of, and a machine for, producing a tufted fabric in which the height of the tuft loops is varied by selectively adjusting the stroke of the tufting needle 32. The needle bar 30 is actuated by an adjustable throw crank mechanism 24 driven by a hollow drive shaft 18 rotatably mounted in the machine. The crank comprises a crank plate 34 fast on the drive shaft and slotted diametrically to accommodate a slide member 36 on which is mounted a crank pin 48 extending through a notch in the cover plate 38 and connected to the needle bar by a connecting rod 50. Springs accommodated in side edge notches on the slide member abut against lugs on the crank plate to urge the slide outwards to a position of maximum throw. A camming rod 54 axially slidable within the bore of the drive shaft is normally biased by a spring away from the crank mechanism, but may be moved axially, by the manual rotation of a cam member 58, towards the crank mechanism when the tapered end 56 enters a camming aperture 52 in the slide to force the slide to move against the springs to reduce the throw of the crank and thus the stroke of the needle and the height of the tuft loop inserted thereby. The looper and knife elements are arranged on rockshafts carried on a vertically shiftable crosshead member 66 having a shank 68 extending downwards through bearings 70 on a mounting bracket 72. A spring 76 bears upwardly on a collar 74 on the shank to urge the looper element and knife into a position for engaging short tuft loops formed when the needle stroke is short. A pull rod 78 may be connected to a foot pedal or the like for pulling the crosshead downwardly to dispose the looper element in a suitable relationship to the long loops produced by the needle when the needle stroke is long. A common operating means may be provided for shifting the crank mechanism slide member and the looper crosshead from a single operating control. It is also stated that when a plurality of tufting needles are provided these may be arranged for alternate operation as described in Specification 814,857.

Title: Improvements relating to the production of phenols
IPC: C07C37/00
Filed: 1950-09-14
Abstract: Crude phenolate solutions obtained from low temperature tars and having a density of 1.14-1.15/20 DEG  C. are treated with steam to expel the volatile neutral oils and then with a stream of air in small bubbles at about 105 DEG  C. until at least 15 per cent of water has been distilled off and the density has increased to 1.22/20 DEG  C.  Thus the amphoteric impurities are transformed into neutral bodies and when the free phenols are liberated with carbon dioxide they are soluble to a clear solution in dilute alkali hydroxide solutions.  The process is particularly applicable to phenols derived from lignite and extracted in the crude form by the usual methods.

Patent GB-499512-A (GB)
Title: Improvements in or relating to carrier signalling systems applicable to electric protection systems
IPC: H02H1/00
Filed: 1937-08-20
Abstract: 499,512. Protective cut-out systems. GENERAL ELECTRIC CO., Ltd., and WESTELL, E. P. L. Aug. 20, 1937, No. 22896. [Class 38 (v)] In a protective system of the kind in which, on fault in a signalling or power network, high-frequency current is injected into the network and actuates means which operate a protective arrangement, for example, preventing or producing tripping of switches, the injected current consists of a carrier modulated by a finite number, which may be unity, of signal frequencies and the actuating means comprises means for demodulating this current and applying the signal frequencies to the protective arrangements to actuate them, preventive means being adapted to prevent actuation of the protective arrangements if modulation frequencies additional to the signal frequencies are present, for example, generated by the fault. Apparatus similar to that shown is located at each line-end. It comprises a transmitter T comprising a carrier transmitter modulator 1 and generators of modulating frequencies f1, f2, and a receiver R comprising a carrier receiver demodulator 4, the output of which is fed to detectors 8, 9, 10 and hence high-speed relays R1, R2, Rx. The filters 5, 6, 7 respectively pass the frequencies f1, f2 and fx, which latter represents a wide band of frequencies not including f1, f2. When relay S changes over its contact S1, signals are sent to the far end of the line and fed to relays R1, R2 there, so opening contacts 11, 12 and breaking the circuit C to trip, or prevent tripping of, a breaker Since a fault may itself generate high frequencies corresponding to f1, f2, false operation may be produced. Usually, however, fault signals are accompanied by other frequencies within the band fx, which operate relay Rx and close its contact 13, so annulling the effect of the opening of 11, 12. The contacts 11, 12 may alternatively, be arranged, to close, and 13 to open, when the corresponding relays are energized. The invention is applicable to a ring main having one feed-point and distributed loads, the ring-sections having, at each end, breakers trippable by overload or overvoltage, and equipment similar to that shown. The relay S is directional, and determines the direction in which the signals are to be sent, the arrangement being that signals are sent over healthy sections to prevent tripping thereof, whereas no signal is sent over the faulty section, which is tripped out by its overload or overvoltage relays even if the fault produces frequencies which simulate those of the signals and tend to prevent tripping. The Provisional Specification refers also to cessation of an existing carrier, and to the third filter being responsive to 50 cycle modulation.
