IPC: G01P3/46
Filed: 1969-04-25
Abstract: 1,210,798. 798, Automatic speed control. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 25, 1969 [April 30, 1968], No.21312/69. Heading G3R. [Also in Division G1] A voltage dependent upon the speed of a motor and derived from a winding on the magnetic circuit of the motor is compensated for the effects of the armature current by means of a transformer 28. The Specification describes the use of such a transformer with several types of motor. In Fig. 1 the motor has a permanent magnet rotor 1 driving an interrupter contact 2 controlling transistors 12, 13 supplying pulsed D.C. from a source 10 to stationary armature windings 7, 8. The transistors 12, 13 are controlled by transistor 17 according to the difference between a reference voltage across Zener diode 18 and a rectified and smoothed voltage derived from an additional winding 9. A secondary winding 27 of the transformer 28 is in series with winding 9; the primary windings 25, 26 are in series with the armature windings 7, 8 so that the voltage from winding 9 is reduced by an amount dependent upon armature current. Fig.2 (not shown) illustrates a modification in which there is only one armature winding 7. In Fig. 3 (not shown) the invention is applied to a series wound commutator motor the primary of the transformer being in series with the motor and the secondary in series with the output of a bridge circuit detecting the back e. m.f. of the armature. In Fig.4, a three pole motor, which may be an induction motor or have an energized rotor 41 (not shown), has three energized windings 48, 49, 50 and three speed-detecting windings 51, 52, 53 each connected in series with the secondary of an individual transformer 58 to provide a three phase output 61 which may be rectified to provide the speed voltage. In a high speed motor Fig. 5 (not shown) windings 51-53 are replaced by single winding on the core (at 44"); the transformer has two primaries in series with windings 47,49 respectively.

Title: Improvements in or relating to circular cylinder and dial knitting machines
Inventor: SCHMIDT RICHARD
IPC: D04B9/06
Filed: 1953-08-05
Abstract: 783,510. Knitting-machines. HELLIGE & CO., GES., F. Aug. 5, 1953, No. 21640/53. Class 74 (2). Pattern wheels 1 of a cylinder and dial machine are each normally held against the needles by action of a spring-pressed plunger 7 on a suitably inclined face 6 of a lever 4 carrying the wheel at 3 ; but undue pressure on the wheel due, say, to a broken needle, rocks the lever 4 about its pivot 5, to bring the wheel out of the working position. The lever is held in the inoperative position (shown dotted) by the plunger 7, but can be restored to working position by means of a handle 11. The pattern wheel carries bits 25, each having half the lower edge inclined at 26 and resting on an inclined base of a trick 24 in the wheel. All the bits are retained in position by a cover-plate. Some of the bits are thickened laterally at 29. Fabric take-up.-As the take-up assembly rotates around the machine axis, a V-belt pulley 38a runs around inside a V-belt 40 which passes around a stationary pulley 39. The pulley 38a is mounted on the shaft of a cone 42, which is thus rotated. A ring 47, freely rotatable in its own plane and bearing by outer and inner conical faces on the cone 42 and a second cone 44, transmits this rotation to the cone 44 and hence, through shafting, to take-up rollers 31, 32. The speed of take-up is automatically adjusted, as the rollers ascend or descend the fabric, by a rod 49 which is raised or lowered as the roller mounting 33 rocks about its axis 35 and so raises or lowers a holder 48 which locates the ring 47 axially and hence alters the speed ratio between the cones. Rib cam-plate, adjustment.-The rib cam-plate may be adjusted circumferentially of the machine by inserting a key in a hexagonal hole 70, turning a worm 66 and hence worm-wheel 63 and eccentric pin 62, which enters a slot 65 in a member 64 fast on the cam-plate. Stop motions.-When lever 4 moves to inoperative position, a snout 12 on the lever operates a machine-stopping. switch lever 15. A spring 78, adjustable by means of a nut 80 and pin 79, pulls down a lever 76 and so, through pin 75 on a lever 74 carried on shaft 72, tends to rotate the shaft against the pull of the thread, which passes around a wire 73 also carried on shaft 72. Breakage of, or excess tension in the thread causes a contact lever 81 to move from its neutral position, shown in full line, to position 81<SP>1</SP> or 81<SP>11</SP> and so mate with machine-stopping contact 82 or 83.

Title: A method of improving the adhesion of substances to metal surfaces
Inventor: BAUER HEINRICH
IPC: C23G5/00
Filed: 1965-05-24
Abstract: A metal surface is treated to improve adhesion to the surface of substances such as lacquers, printing inks, adhesives or high molecular weight substances used for coatings or linings, by the application of a high frequency say 25 to 75 kc/s, high tension alternating field at a voltage exceeding 50,000 volts.  The metal surfaces may be a sheet, strip or foil of aluminium or aluminium alloy semifinished stock of processing length e.g. cut sheets, tubes. Coating materials mentioned are polyolefins e.g. polyethylene.  The treated metal surface may be coated with metals by spraying, vaporizing, or plating.  The alternating field may be provided by fixed electrodes, or electrodes in the form of rotating barrels, optionally cooled, with the metal surface forming the counter electrode which is continuously fed tangentially past the barrel electrode.  The metal surface may be consecutively exposed to several alternating fields, and both sides of the metal may be treated by one or more electrodes simultaneously.  The treatment may be combined with known treatments such as an adhesion-assisting lacquer (priming) process, anodic oxidation, phosphatisation, and may follow a degreasing treatment.  In the Examples, (2) annealed aluminium foil after electrical treatment is coated with a high pressure polyethylene, by extrusion; (8) electrically treated aluminium foil is faced with polypropylene foil with the aid of a polyesterpolyisocyanate adhesive; (10) aluminium foil is treated electrically to accept printing, lacquering or facings without further treatment.
