Title: Improvements in or relating to cloth stentering machines
IPC: D06C3/00
Filed: 1919-07-23
Abstract: 144,906. Farrel, E. July 23, 1919. Tentering. - For straightening the weft in tentering-machines, a friction clutch is interposed in each chain drive, loaded by a spring or the like, so that sufficient power is transmitted normally to traverse the chains, but slipping is allowed when the weft lies obliquely. A separatelyoperated weft-straightener may be contained with the friction drive. The chain wheels a, Fig. 2, are driven by pinions b but have coned recesses c receiving cone clutches d. These are splined on shafts e and kept in engagement by springs f<1> adjustable by wheel-nuts j and acting on the clutches directly or through levers h, when a second spring f<2> may be provided to render the device more sensitive. The slip prevents tearing of the selvages in the event of a jam. Other forms of friction clutches may be used, such as a disk clutch consisting of disks l, m, Fig. 4, connected to a cylindrical extension k of the driving- pinion n<1>, which is controlled by the clutch in this modification, and to a collar splined on the shaft n, respectively. A collar s acted upon through a fork by the screwed spindle t controls the spring. In this modification, also, one side of the machine is provided with a manually operated weft-straightening differential consisting of a sunwheel p, planet-wheels q, and a bevel-wheel r connected to the chain wheel a. The disks l of the clutch may be mounted on the sun-wheel p.

Title: Improvements in or relating to magnetic means for the detection of the quality of steel
IPC: G01R33/12
Filed: 1942-12-29
Abstract: 562,563. Magnetic tests and measurements. APPLEBY-FRODINGHAM STEEL CO., Ltd., and REEVE, L. Dec. 29, 1942, No. 18464. [Class 37] An arrangement for testing the quality of magnetic material such as steel comprises one or more yokes of magnetic material applied to the test piece so as to form therewith a magnetic circuit system, primary and secondary windings arranged on this system, the primary winding being wound in sections which are magnetically in opposition and are such that the flux in one direction preponderates over that in the other, means for energizing the primary winding, and means for measuring the current consequently induced in the secondary winding. Three primary windings 3 are arranged as shown on the yoke 2 applied to the test piece 1 and are connected in series so that two of the windings produce flux in one direction and one produces flux in the opposite direction. A secondary winding 4 is provided at one extremity of the yoke 2. The primary winding is supplied by means of a battery 5 through a switch 6 and the current induced in the secondary winding 4 when the circuit is made and broken is measured by a milliammeter 7. A rheostat 8 and an ammeter 9 are provided for adjustment of the primary current to a standard value. In a modification, the coils are placed on the test piece 1, the three primary sections being arranged end to end and the secondary winding beyond one end of the set of primary sections. Two, yokes may be employed, both applied to the steel piece under test, one carrying the primary winding and the other the secondary winding.. In this case the yoke carrying the secondary winding only receives the leakage flux which fails to pass through the primary magnetic circuit, so that the greater the permeability the less the secondary current. The yoke may be provided with polepieces shaped to fit the surface of the test piece. Alternating current may be employed instead of direct current, the instrument 7 then being modified for use with alternating current.

Title: Process for extracting valuable substances from synthetic process gases
IPC: B01D53/04
Filed: 1937-07-02
Abstract: In the use of solid absorbents for separating the products of synthesis from hydrogen-carbon monoxide mixtures the unsynthesized gas mixture is passed through the regenerated adsorbent for drying and cooling the latter.  The further advantage results that the final traces of impurities are thereby removed from the crude gas mixture. When the original water gas has been enriched in hydrogen by catalytically treating a portion of it with steam, this converted portion is preferably used for drying and cooling the adsorbent, with the advantage that its carbon dioxide content is reduced.

Title: Improvements in or relating to control apparatus for synchronous electric machines
IPC: H02P9/14
Filed: 1951-08-10
Abstract: 718,023. Automatic control systems for synchronous machines. GENERAL ELECTRIC CO., Ltd., FRIEDLANDER, E. S., MILNER, M.,.and GARDINER, H. W. B. Aug. 7, 1952 [Aug. 10, 1951], No. 18883/51. Class 38(4) [Also in Group XXXVI] In an automatic control system for a synchronous alternator (or motor) in which the reduction of field excitation on leading (or lagging) power factor loads is limited to maintain stability, the load current power factor is measured by comparing the phase of the output of a permanent magnet alternator driven by the shaft of the synchronous machine with that of tse main A.C. supply to or from the machine. The machine 10, Fig. 1, shown an an alternator, has a voltage regulator 16 energized from a potential transformer 15 via resistors 30, 31. The transformer 15 also energizes one winding 20 of a relay of the kind disclosed in Specification 613,856. The other winding 26 of the relay is energized from a permanent magnet alternator 12 driven by the main alternator 10. The armature 25 of the relay takes up a position dependent upon the phase relationship of the currents in the two windings and when the angular displacement between the magnetic axis of the rotor of the alternator 10 and the axis of the effective field thereof exceeds a predetermined amount, movement of the armature 25 causes contacts 27, 28 to be closed to energize motor 37 to rapidly increase the value of resistor 30. If the angular displacement is reduced, contacts 27, 29 energize motor 37 to slowly reduce the value of resistor 30 and also energize relay 33 which short-circuits resistor 27, 29 to open early and prevent overshoot of motor 37. In a modification, Fig. 2, a further resistor 52 is connected into circuit when the motor 37 is energized to increase the resistance 30 and so reduce the overshoot of the motor when running in this direction also. Additionally, the relay winding 26 is energized with alternating current having two components, one derived from the permanent magnet alternator 12, the other derived from the potential transformer 15 via a resistance condenser network 56, 55 dimensioned so that this component is equal and opposite to the component derived from the alternator 12 under normal conditions. In another modification; Fig. 3 (not shown), the ,second component is applied to an auxiliary winding on the relay. Specifications 662,761 and 706,992 also are referred to.
