Title: Improvements in or relating to wringing machines, mangles, calendering presses and the like
Inventor: SHAW JOHN
IPC: D06F45/00
Filed: 1947-10-27
Abstract: 647,649. Wringers. PARNALL (YATE), Ltd. Oct. 27, 1947, No. 28626. [Class 138 (ii)] A wringing machine has a fixed frame member which provides the main support for the rollers, in which one roller is rotatably mounted in a fixed bearing and a second roller is rotatably mounted upon a bearing carried by an arm which projects from the frame member into the second roller, the arm being mounted in such a manner that spring pressure imparted to it by a resilient pivoted lever causes the second roller to be urged against the first roller. The lower portion of a frame member 1 is fitted with a rigid extension tube 4. The foundation tube 5 of a roller 2 is mounted over the tube 4 and fitted into the outer race of a roller bearing 6, the inner race of which is fitted to the tube 4 within the frame 1. The tube 5 is fitted to the outer race of a roller bearing carried by a cage 11, the inner race of which fits into the outer end of the tube 4. The outer race of the bearing is rotatable with a spindle 8 passing through the tube 4 and supported therein by a bearing 9, which spindle is rotated by a handle 10. The foundation tube 12 of a roller 3 is supported by and rotates with a roller bearing carried by a cage 13, which bearing is fitted to the outer end of a rigid steel arm 14 making bearing contact with the frame at 15. The other end of the arm 14 is connected by a bolt 16 to the end of a laminated spring lever 17 pivoted on the frame 1 at 18. The free end of the lever 17 is engageable with a screw spindle 19, which passes through the arm 14 and has a hand wheel 20 fitted to its upper end. When the spindle 19 is screwed downwardly the lever 17 pivots about 18 to cause the arm 14 to move the roller 3 into pressure engagement with the roller 2. A split-spring washer 23 is fitted on the spindle 19 between the hand wheel 20 and the arm 14, and the additional resistance offered by the washer, when screwing down the spindle 19, serves as a warning to the operator to cease further compression of the laminated spring lever 17. When the pressure between the rollers is completely released the free end of the lever 17 abuts against a stop 22 fixed to the arm 14 adjacent to the screwed spindle 19. Instead of the spring washer warning device, a stop may be provided below the free end of the lever 17. The lever 17 may be made of resilient steel in lieu of the laminated construction. Specification 634,731 is referred to.

Title: Improvements in the manufacture of acidylated aromatic amines
Filed: 1930-08-15
Abstract: Diacidyl aromatic diamines are obtained pure and in a fine state of subdivision suitable for incorporation in cellulose ester spinning solutions by treating a base containing two benzene residues linked directly as in benzidine or linked through an atom or group as in diphenylether and containing two amino groups with benzoic anhydride or other aromatic acid anhydride.  In order to obtain the diacidyl compounds in a finely-divided state the acidylation is carried out in dilute solution, suspension, or dispersion, preferably at under boiling temperature with or without a wetting agent.  The formed products may also be treated with wetting agents.  They may be ground either wet or dry in order to reduce the particle size still further or they may be worked directly with the solvent to be used for the spinning solution or with the spinning solution itself for use as described in Specification 346,678.  The starting materials may be purified as in Specification 363,986.  In an example, purified benzidine is suspended in an excess of water, finely-ground benzoic anhydride is slowly added at 20-30 DEG  C., and after further heating at 90 DEG  C. the mixture is made alkaline and the dibenzoylbenzidine filtered, washed, treated with acetone and incorporated in the spinning solution.  The Provisional Specification refers to the use of acid anhydrides in general.

Title: Improvements relating to the synchronisation of electric machines
IPC: H02J3/42
Filed: 1934-10-10
Abstract: 444,270. Electricity supply. TAYLOR, M. K., and FERRANTI, Ltd., Hollinwood, Lancashire. Oct. 10, 1934, Nos. 28989 and 37239. [Class 38 (iv)] Synchronizing.-Electric machines or systems are synchronized by a grid-controlled discharge tube associated with electric means preventing flow of anode current until voltages derived from the two sources are within predetermined limits, both the anode current and the grid biassing voltage being dependent upon the amplitude, phase and frequency of both systems. A generator with output-terminals 1, 2 is connected to bus-bars of a circuit having terminals 3, 4 by means, not shown, operated when the two are in synchronism, by a switch energized from contactors 42, 43, which are connected by relay 31 when current flows through the valve 18. The valve is associated with the generator and the mains circuit through transformers with primary windings 5, 11, each with three secondary windings. The main anode current is supplied by secondary windings 7, 14 in series, the discharge circuit being completed through contacts 28, 29 when relay 31 is operated. A permanent bias is applied to the grid 17 by secondary windings 9, 15, rectifier 25 and potentiometer 20, through adjustable contact 19 and resistance 23. A negative variable bias is applied to the grid 17 by opposed secondary windings 8, 13 through rectifier 16, condenser 24 and resistance 23. When the two sources of supply are synchronized for a sufficient period, the negative bias thus applied to the grid is reduced to zero and the tube 18 is rendered conducting. Relay 31 is thus operated by winding 44 and contacts 42, 43 are closed to operate the main connecting switch. Contacts 40, 41 are also closed so as to energize hold or coil 39 for relay 31 and pull off coil of relay 30. Contacts 37, 38 being disconnected to cut out the circuit to the cathode heater 36 and contacts 28, 29 break the main discharge circuit through the tube 18. When the generator is switched out, relay 31 is restored to the contacts open position and relay 30 to the contacts closed position, thus rendering the discharge tube ready for operation whenever switch 12 is closed. In a modification, the variable bias is applied to the grid by independent transformers instead of the secondary windings 8, 13, the secondaries of the transformers being so connected that they act in the same direction when the generator and main circuit are in phase. Sharp peak outputs may be obtained by the use in the transformer of cores of such shape and material that they are quickly saturated.

[Also in Group XXXVII] A shaft 3 carrying wipers 4 also carries one or more drums 6 on which are mounted exchangeable keys 7 having different arrangements of notches 8 for the selective operation of sets of contact springs such as 18, five sets being indicated at 19, Fig. 1. The shaft 3 is stopped in a required position by an electromagnetically actuated pawl 11, Fig. 2, which engages a ratchet wheel 10, the impact being reduced by the use of a resilient coupling between the wiper carriage and the key drums 6. A selected key 7a is now opposite a row of tags 12 pivoted at 23 to a common lever 14 which is secured to the armature 15 of an electromagnet 16. Energization of the electromagnet 16 causes some of the tags 12 to enter notches 8 in the selected key 7a, pulling associated catches 20 to change over corresponding contacts 18. Those tags 12 which are not opposite notches 8 turn about their pivot 23 against springs 24 and are disengaged from their associated catches 20. The actuated catches 20 are held by spring latches 25 until released by a common unlatching member 26. Instead of the electromagnet 16, the shaft driving the wiper carriage or some other means may be used to actuate the tags 12. In a modification, Fig. 5, only those tags 12 which are not opposite notches 8 actuate their associated catches 20.

[Also in Group X] A hydraulic jack for tensioning concrete reinforcements of helically disposed stranded wire comprises a hollow piston 4 located in an anunlar space 3 between an outer body portion 1 and an inner sleeve 2, in which relative rotational movement of the hollow piston 4 and outer body 1 is positively prevented, e.g. by the provisions of dogs 34 on either the hollow piston or outer body. portion co-operating with splines 35 on the other. The jack at its outer end includes hydraulically operated segments 14 for temporarily gripping the ends of the reinforcement wire, and is provided at its inner end with a hydraulically operated ram 41 which drives home wedges &c. which permanently retain the reinforcement wire in its stressed condition in the concrete. In operation of the jack, the hollow piston 4 is extended by introducing fluid into the chamber 19 through a port 17 and the initial movement of the piston moves an abutment block 30 away from a ring 32 and permits a compressed rubber ring 16 to thrust a segment retaining block 13 into a taper 12 so that the temporary gripping segments 14 engage the wire passing therethrough, and continued movement of the piston tensions the wire. The ram 41 is then operated to drive the permanent retaining wedges by fluid introduced into a chamber 43 through a port 42, and the jack is retracted by fluid introduced into a chamber 21 through a port 18. Towards the end of the retracting stroke the abutment block 30 on the piston 4 engages the ring 32 on the inner sleeves 2, but the outer body 1 continues relative movement to the left so that a duct 26 is opened allowing fluid to pass from the port 18 to a chamber 27 to act upon a piston 28 which in turn acts upon a block 13 to release temporary gripping segments 14.
