Patent GB-728492-A (GB)
Title: Improvements in and relating to systems for controlling the tension in a length of material between winding and unwinding rolls
IPC: B65H23/18
Filed: 1953-11-23
Abstract: 728,492. Automatic speed control systems. GENERAL ELECTRIC CO. Nov. 23, 1953 [Nov. 22, 1952], No. 32448/53. Class 38 (4). [Also in Group XXXVII] The tension in an electric winder system is automatically controlled by varying the field of the braking-generator and a booster in series with it to maintain the loop current substantially constant. In addition the field of the braking-generator is reduced in steps during the wind so that the control works over a small range. Circuit arrangement.-The winder comprises a drive motor 5 and a braking-generator 11 connected to a main generator 6, and mechanically coupled respectively to winding and unwinding rolls 3, 2. A booster 12 in series with the braking-generator is energised by a metadyne exciter 14 controlled in accordance with the braking-generator current (IR drop across resistance 19). The braking-generator field 11a is energized from the exciter 14 in series with the auxiliary D.C. supply busbars 8, 9 and in addition a relay 20, having a reference winding 20b and a winding 20a energized from the booster 12, operates a sequencing relay 30 controlling slugged relays 21 ... 24 which connect resistances 13a, 13b in series and parallel with the braking-generator field winding. These relays are set up at the beginning of each wind by a push-button 135. Operation.-As the diameter of the unwinding roll decreases, the speed of the braking-generator increases tending to increase its armature current. This results in a decrease in the field excitation and a decrease in the booster voltage until relay 20 drops out initiating the release of relay 21 to insert resistance in the braking- generator field. This causes a reduction in the generator armature voltage which is automatically compensated by an increase in booster voltage, Fig. 4, causing the relay 20 to pick-up again. As unwinding proceeds this cycle repeats as relays 22 ... 24 are released to weaken the braking-generator field. Alternative embodiment. Fig. 2 (not shown).- The relays 20 ... 24 may be replaced by a motordriven rheostat 45, 46 in the braking-generator field circuit. In this case the booster is provided with a reference field which is opposed by a field energized by the amplidyne exciter; thus the exciter voltage increases to decrease the booster voltage, until it reaches e.g. 8 volts, when the forward non-linear characteristic of the rectifier 47 allows energization of the rheostat-motor 46 to insert a block of resistance in the braking-generator field circuit. Specification 539,835 is referred to.

Title: Improvements in and relating to brake or clutch operating and adjusting gear
IPC: F16D65/60
Filed: 1926-12-23
Abstract: 287,633. Enderby, G. H. Dec. 23, 1926. Clutches, friction.-In a brake or clutch automatic-adjusting gear the shoes are pivotally mounted on pins b eccentrically arranged on a disc a capable of being rotated in one direction through the shoes or the shoe-actuating means, when the gear is operated, in order to move the shoes nearer the brake drum, the disc being adapted to be held against reverse rotation. In Fig. 1, operation of the shoes d by the cam f brings about movement of a ratchet rod h pivoted to one shoe between the arms of a bifurcated rod h<2> pivoted to the other shoe and carrying spring pawls j. If the relative movement of the rods is greater than one tooth, due to wear, the pawls engage a succeeding tooth and on release of the brakes the shoes d will be moved about their pivotal connections with the rods h, h<2> by the return spring g and the disc a is rotated and maintained in its new position by stationary pawls a<2>. In a modification shown in Fig. 2, an extension f<3> from the brake cam-operating link f<2> is adapted to operate a lever a<3> carrying a pawl a<4> which is moved over a ratchet disc a which, when the pawl is moved sufficiently to take up a tooth, is rotated on release of the brake and rotates the disc b on the same shaft, the disc coacting with stationary pawls a<2>. In this modification the brake may be applied by moving the brake applying gear in the opposite direction; in this case the wear is taken up when the brake is applied. In a further modification the brake cam is geared to a plate mounted on the same shaft as the ratchet disc a carrying the pins b but adapted to rotate relatively to it and carrying a pawl coacting with the ratchet disc a. Only a limited number of teeth are provided on the ratchet disc so that the automatic adjustment stops when the brake blocks are practically worn away. The invention is shown applied to two brakes arranged side by side, the cam f and disc a for one brake being mounted on sleeves through which pass the shafts for the cam and disc of the other brake, the adjusting gear of which is arranged as in Fig. 2, and the adjusting gear of the other brake as in the geared modification. In a further modification a disc carrying the pins b is 'rotated by the disc a through worm gearing. The cam operating lever may be connected with the operating rod by means of a spring-controlled pin and slot connection to allow slight differences in a series of brakes to be taken up. More than one pawl a<2>, a<4> or j may be provided to take up movements of the ratchet disc equal to fractional parts of its teeth. When the invention is applied to a clutch the cam is operated by a link connected at one end, eccentrically, to a disc on the cam spindle and at the other end it engages an inclined or spiral slot in a sleeve sliding axially and splined on the shaft l. The sleeve is provided with an annular groove for the operating fork.

IPC: F16D48/06
Filed: 1954-11-17
Abstract: Varnishes for impregnating the coil of an electro-magnet in two stages are as follows.  The coil is first vacuum- and pressure-impregnated with a varnish of the phenoplast type produced by the condensation of formol (30 per cent solution) and of cresol, with an added oil drier to 65-90 per cent by weight of the cresol.  A natural resin plasticizer is added and the mixture dissolved in trichlorethylene.  The coil is then dried at 80 DEG  C. and a second impregnation effected, after which it is baked for six to ten hours at 110 DEG  C., which leaves the varnish still incompletely polymerized, in which condition the coil is suitable for transportation but can still be shaped.  The coil is then installed in its housing, which is filled with a varnish similar to the above but capable of more rapid polymerization, the drying oil now being in the proportion 40-60 epr cent of the weight of the cresol.  No plasticizer is added and the varnish is heated to 80-100 DEG  C. for fluidity.  The unit is next baked six hours at 115 DEG  C., six at 125 DEG  C. and eight at 170 DEG  C., which polymerizes the second varnish and completes the polymerization of the first.
