Abstract: 820,799. Dynamometers. KLINGER MANUFACTURING CO. Ltd., GILCHRIST, R. S., and MATTINGLY, D. A. E. April 8, 1957 [April 6, 1956], No. 10637/56. Class 106 (2). [Also in Group VIII] Apparatus for detecting and measuring faults in knitted fabric comprises means for applying equal stretch to the wales of between two predetermined courses of loops and means for comparing the tensions in the wales when so equally stretched. Two L-shaped. members 10 are rigidly fixed to the frame 11 and pivotally carry the rod 12 which is fixed to upright members 13 and has a weight 15 cantilevered to it. Two circular rods 18, 19 are inserted, e.g. into the open-sided welt of a stocking fabric and are then placed over the members 10, 13 to be held in V-grooves 17, 16. The rod 19 has a groove 23 which is held in its correct position opposite a feeler element 34 sensitive to tension in the fabric by a finger 21a engaging a bracket member 22. The feeler, which engages at least two loops of fabric, is held against these loops by the action of a spring 31 working a pivoted lever 33 which carries the feeler and which is traversed across the fabric by a block and screw 26 and 27. Also fixed to the lever 33 is a holder 37 for a pen or scriber 38 which records variations in tension of the fabric on the paper or tape 39. To compare tensions in the two halves of the fabric the tape may be moved relative to the pen so that the graphs for the two halves are superimposed. The rods 18 and 19 may be permanently fixed to the members 10 and 13 in cantilever fashion.

Title: Comparator
IPC: H03K5/24
Filed: 1972-03-08
Abstract: 1315109 Amplitude comparator circuits WESTINGHOUSE AIR BRAKE CO 8 March 1972 [15 March 1971] 10671/72 Heading H3T In an amplitude comparator, the output of an oscillator is applied to a frequency dependent output circuit and the operating frequency of the oscillator depends upon the relative value of two signals applied to the oscillator. The frequency of the multivibrator shown depends upon the ratio of V1 to V2 and it is arranged that when these are equal the oscillation occurs at the resonant frequency of an output tuned circuit S, C3. If the voltages depart from equality the output from the tuned circuit is reduced. This output may be amplified and fed to a rectifier to produce a D.C. signal. The tuned circuit may be connected to one transistor only.

Title: Synthetic lubricaint oils from hydrogenating catalytic cracking of very high viscosity polymers
IPC: C10M107/10
Filed: 1974-03-11
Abstract: The process for producing synthetic lubricating oils of high viscosity index, high thermal stability and extremely low carbonaceous residue starts from polymers of extremely high viscosity, having a boiling point above 175 DEG C. These polymers are obtained by polymerisation of normal alpha-olefins of the general formula R-CH=CH2, where R is an alkyl radical having 2 to 16 carbon atoms. The polymerisation is carried out in the presence of the TiCl4/polyimine-alane catalyst in an atmosphere which is inert or at least partially replaced by hydrogen. These polymers are subjected to a catalytic hydrocracking treatment at temperatures varying from 300 to 400 DEG C. The hydrogen pressure is between 20 and 200 kg/cm<2>. The product is then distilled in vacuo up to a top temperature of 400 DEG C, relative to atmospheric pressure. Finally, the fraction of boiling point above 400 DEG C is separated off.

Abstract: 885,095. Pneumatic separating. PETTIBONE MULLIKEN CORPORATION. April 9, 1958 [June 13, 1957], No. 11173/58. Class 117. Apparatus for removing impurities from foundry sand includes a hopper 14, Fig. 1, with outlet hoses 24 supplying the first of a number of identical units 28, 30 rearranged in series, and each unit is divided by a partition 89 into two compartments 90, 92 (Fig. 3) each feeding, by gravity, two downflow conduits 34, 36. Each pair of downflow conduits leads to an impact and mixing unit 32 which is of shallow box form with axially opposed air inlets 150, (Fig. 8) supplied with air via a blower 46, surge tank 44, and conduits 40, 38, and the sand is fed under the control of valves 158 to each air stream. The sand-carrying airstreams collide centrally of the unit and flow upwardly through an outlet 108 and a conduit 42 back to the feed compartment. As shown in Fig. 3 each conduit 42 extends into a compartment so that the stream of sand and air emitted from it strikes an impact plate 114 housed within a box-like structure 116 with cut-away portions 121 in its side walls to facilitate lateral outflow of air to the upper part of the unit. Sand falls downwardly onto a transversely extending deflector plate 122 whereby some of it is directed through an outlet in a partition 89 to the next compartment for further treatment and the rest is returned to the down flow conduits of the same compartment for recycling. The last unit of the series has an outlet conduit 60 with an adjustable cut-off device 62 which may control the operation of the whole system. The upper end of each unit has an outlet 54 connected to a suction fan 50 whereby the loosened impurities and other fines are carried away. Two inclined baffles 172, Fig. 2, extend across the units below the outlets 54 and provide a slot 174 for the downflow of heavier particles.

Abstract: 399,571. Welding wire fabric. SOUTHERN, J. H., 41, Newcomen Terrace, Redcar, Yorkshire. April 19, 1932, No. 11217. [Class 83 (iv).] In a machine for making wire fabric the warp wires are continuously fed, the weft wires are intermittently laid in pairs upon the warps and the joints are welded by electrodes travelling at the speed of the warp. The tension on the warp is released during welding. The warp wires are fed under a tension pulley b over a rotatable grooved welding drum with welding heads f past a tension roller g and drag roller d to a reel m. The weft wires may be fed by apparatus described in Specification 393,346, [Group XXIV], in pairs to stationary clips 35, 36 and are transferred by pusher rods 38 actuated by a cam 55 to clips 5 on the drum. The clips are held closed by gravity and release the wefts after welding. Transformers j, mounted on a platform k, are wired to electrodes l on a rocking head r supported on arms s at each end of the drum. The electrodes are lowered to effect welding by a cam-actuated lever 11 connected through a cross-head z with the arms s. The lever 11 is connected to a lever 13 which raises the roller b to release the warp tension during welding. On the downward movement of the head r pins 73 on the arms s engage notches 72 on discs 71 rotating with the drum. The welding head is then moved with the drum until the head is lifted and the pins are released. A cam 29 then swings the head back to its starting position. The parts are driven by appropriate gearing from a shaft 62.

A multifeeder circular interlock machine has yarn feeders arranged in pairs so that when the machine is producing interlock fabric the appropriate needles receive yarn and knit at the respective feeders in the normal manner. When, however, it is desired to produce a rib portion attached to the interlock portion of the fabric the leading guide of each pair of feeders is raised from its normal yarn feeding position to a position where the yarn as it is taken by the last needle to receive it at that feeder engages with a recess in or portion of the yarn guide of the trailing feeder so that the two yarns of each pair of feeders are fed simultaneously at the trailing feeder to those needles which normally knit at that feeder. This thereby causes a 1 X 1 rib portion to be produced in which the yarns of the two feeders are knitted in plated relationship, the intervening needles which still continue to be actuated by the earns at the first or leading feeder casting off their last loops as they are so actuated. U.S.A. Re-issue Specification 925,393 is referred to.

Title: Improvements in telephone systems
IPC: H04B1/58
Filed: 1922-04-22
Abstract: 178,860. Ges. f³r Drahtlose Telegraphie. April 23, 1921, [Convention date]. Telephone systems and apparatus.-In a substation bridge arrangement, singing, due to the passage of received currents through the transmitter when one of the bridge arms becomes unbalanced owing to a variation in the resistance of the line conductors, is avoided by a back-coupling between the unbalanced arm and the transmitter circuit. Such an arrangement is shown in Fig. 3, in which the line conductors 1 are initially balanced by the arm 2. The receiver 5 (which may be a coil coupled to the detector circuit of a receiving aerial) is connected between the junetion of the bridge arms 1, 2 and the mid-point of a subsidiary winding 6 in parallel with the winding 3 coupled to the transmitter 4 (which may be a thermionic generator associated with a transmitting aerial). One side of the winding 6 is coupled to the transmitter circuit through a winding 7 and a three-electrode amplifying valve 8. When the balance in the two halves of the winding 6 is upset owing to a change in the resistance of the line 1, received currents cause currents to flow in the windings 6 and 3, but the transmitter 4 is unaffected since a neutralizing current is induced in the transmitter circuit through the back-coupling 7. The valve 8 is arranged to have a limiting action in order to prevent the back-coupling 7 from interfering with transmission. A modification is described in which the valve 8 is omitted, the winding 7 being connected in series in the transmitter circuit. The invention is applicable to both high and low frequency telephony along conductors.
