In an installation for the continuous coating of tubes, bars, &c., with a liquid product, e.g. insulating material, the tubes 1, Fig. 1, are placed on pairs of rollers 2, each pair of which consists of rollers 2a, Fig. 7, mounted on shafts 2b carried by brackets 2c. These brackets are carried by shafts 2d mounted in supports 2e which are slidably mounted in a support 2f . The lower end of each support 2e is connected to a strap 2m which is joined by pivoted links 2j to trunnions 2i on a nut 2h. Each nut is mounted on a rotatable screw 2g. The tubes are transferred from the rollers to a driving arrangement, Fig. 2, by a finger 3 carried by an endless driving cable 4. The driving arrangement comprises three wheels 6, each of which is mounted on a pin 6a carrying a worm wheel 7a. Each worm wheel is engaged by a worm 8, the casing 7 of which is mounted on a plate 16. One end of this plate is pivotally supported at a and the other end is supported by a pin 16a, Fig. 3a, from a plate 18. A spring 17 surrounding each pin allows the wheels to move outwards when passing over a thickened part of the tube. One end of the plate 18 is hinged at b and the other end 18a is received in a spiral slot 19a formed in a rotatable disc 19 which can be turned to enable the apparatus to drive tubes of various diameters. During this movement the plate is guided in a fixed radial slot 19b. Each worm 8 is driven either by a pinion 10 or a pinion 11 mounted on a shaft 10a which is journalled in a driving wheel 21. Each shaft 10a is connected to the worm shaft by a universal joint 9 mounted in a bracket 21a on the wheel 21. The pinions 10, 11 are engaged by gears 12, 13 respectively, either of which can be held against rotation by the application of a brake. The tube is fed by the rollers 6 into position over a tank 23 containing hot insulating material which is tipped over it by rocking devices 22. Consecutive tubes are coupled by hooking together complementary members 24a, 25a which are inserted in the ends of the tubes and frictionally locked thereto. The leading tube 1b is pushed by the following tube la on to carriages 27, 26 and is disengaged therefrom by the rotation of the tube 1a.

Filed: 1976-03-01
Abstract: 1532032 Control of AC motors SONY CORP 1 March 1976 [5 March 1975] 08087/76 Heading H2J Braking apparatus for an A.C. motor, consisting of a first winding in parallel with the series combination of a second winding and a capacitor, comprises an A.C. source to apply current to the motor, a rectifier circuit connected to the A.C. source to produce a D.C. voltage, a smoothing circuit connected to the rectifier circuit, and a switching means having a first terminal connected to the smoothing circuit and a second terminal connected to the connection point between the second winding and the capacitor, operation of the switching means to complete the path between the first and second terminals enabling D.C. from the smoothing circuit to flow through both the first and second windings to brake the motor. Fig. 2 shows the application of the invention to brake a single-phase induction motor driving -the turntable of a record player, the motor having main and auxiliary windings M, S connected with a phase-lead capacitor C1 and supplied with A.C. through a transistor Q1 and the appropriate diodes D1-D4 of a rectifier bridge DB. A servo circuit 3 produces a control signal E c  to maintain the impedance of transistor Q1 at a predetermined value corresponding to a desired constant motor speed. The signal E C  also removes a braking signal V to switch off transistors Q2, Q3, the latter disconnecting from circuit point c the output voltage of a rectifier and smoothing circuit D5, R1, C2, C3 energized by the motor supply 2. When the turntable is to be stopped or slowed (e.g. from 45 to 33 r.p.m.), the signal E C  is removed to switch off transistor Q1 and produce the signal V, which switches on transistors Q2, Q3 to apply D.C. to the windings M, S and so brake the motor. The equivalent circuit for the braking condition is described, Fig. 3 (not shown). The circuit D5, R1, C2, C3 may be connected to point c through a switch (K1) mechanically operated by a coupling with a switch of the servo circuit 3, Fig. 1 (not shown). The latter switch (S) controls the application of the signal E C  to the transistor Q1 and, in the case of Fig. 2, to a transistor (Q6) controlling the transistor Q2, Fig. 6 (not shown). Additional transistors and resistors may be provided to control a high output voltage of circuit D5-C3, Fig. 4 (not shown), or to amplify the signal from transistor Q2, Fig. 5 (not shown).
