Title: Improvements in or relating to the Regulation of Dynamo Electric Machines.
IPC: H02J7/22
Filed: 1917-07-13
Abstract: 112,415. Remy Electric Co., (Assignees of Conklin, O. F.). Dec. 19, 1916, [Convention date]. Brush-holders; exciting; auxiliary protective or safety devices.-The output of a dynamo-electric machine is regulated by a thermostat 4, Fig. 2, which is influenced by the heating of the commutator 20. Fig. 8 shows the application of the invention to a variable-speed dynamo for lighting and battery-charging; the field-magnet winding 13 is connected between an auxiliary commutator brush 33 and one of the main brushes 28, a resistance 48 being thrown into circuit or short-circuited according as the contacts 45, 46 of the thermostatic switch 4 are separated or in engagement. When the current is excessive, the resistance is adapted to fuse and break the circuit. The thermostatic switch is attached to one of the main brush-holders. The main brush-holders 26 are carried by a plate 22, Figs. 2 and 4, which is mounted adjustably on the head plate 16, Fig. 3, by means of elon. gated slots 23 and screws 24. The holder for the auxiliary brush 33 is carried by a second plate 31 having slots 34 therein, through which project studs 35 carried by the plate 22. Spring washers 36 are placed between the heads of the studs and the plate 31 to prevent independent movement of the plates. The plate 31 may be moved relatively to the plate 22 by applying a screw-driver to a stud 37 which carries a pinion 38 meshing with teeth 39 on the plate 31; both plates may be moved together by loosening the screws 24 and turning the stud 37.

Title: Improvements in or relating to high-voltage insulators
IPC: H01B17/04
Filed: 1956-04-03
Abstract: 856,043. Insulators. PILKINGTON BROS. Ltd., and HOPWOOD, W. March 20, 1957 [April 3, 1956], No. 10196/56. Class 36 In a glass insulator 1 for use with high-voltage power lines, the head 2 of the insulatingportion is of a thickness such that it acts as the dielectric of a capacitor of such capacitance that the operative impedance of the bead is not more than that of the exposed part of the insulator under atmospheric conditions. A cap 6 and pin 7 are cemented to the insulator by a cement which may have sufficient conductance to bring the bead of the insulation portion into electrical connection with the cap and pin. Alternatively the surfaces of the bead may be metallized and connected by wires to the cap and pin. A number of such insulators may be flexibly or rigidly joined together to form an assembly and a number of these assemblies may be flexibly joined together. Specification 856,042 is referred to.

Title: Process for producing permanent mechanical effects on textile fabrics, especially on light-weight fabric
IPC: D06M15/423
Filed: 1955-04-13
Abstract: In a process for fixing mechanical effects upon textile fabrics with the aid of thermosetting synthetic resins, the fabric is shrunk with an alkali hydroxide solution prior to the application of the resin. Lightweight cotton fabrics may be so treated and the alkali hydroxide may be applied to the grey, kier-boiled or bleached fabric.  The alkali hydroxide may be sodium hydroxide at 22 DEG -30 DEG B<\>ae or potassium hydroxide at 24 DEG -30 DEG B<\>ae.  The mechanical effect may be goffering, Schreinering, moire or calendering, with or without friction, and may be fixed with the aid of aqueous solutions of precondensates of formaldehyde with urea, thiourea, ethylene urea and its homologues, urein, acetylene diurein and its derivatives, dicyandiamide, melamine, phenol or phenol derivatives or mixtures of these precondensates, or ketone-aldehyde or dimethylol-uron precondensates, which may contain acid or alkaline catalysts, dyestuffs, pigments or metal powders.  The fabric may be dyed prior to or after the resin treatment and the resinous solution, which may contain dyes or pigments, may be printed; also, the resinprinted fabric may be colour printed.  The resin is cured by heating after the mechanical treatment and the fabric may be aftertreated with dilute sodium or potassium hydroxide solution, which has a swelling effect but not shrinking effect, or with an alkali hydroxide solution of mercerizing strength.  The ground of the fabric may be transparentized or parchmentized with sulphuric acid.  In the examples cotton fabrics are treated with alkali hydroxide solutions after, between or before kier boiling and bleaching treatments and after rinsing and drying, either in the loose state or on a tenter or under tension, are impregnated with the resin solution, dried at 40 DEG C., mechanically treated, in one case by embossing at 200 DEG C., and cured at 140 DEG C., whereafter they are rinsed and dried on a tenter or under tension.  In examples (2) and (3) the fabrics are aftertreated with sodium hydroxide and potassium hydroxide, respectively, at 20 DEG B<\>ae and in examples (6) and (7) the fabrics are after-treated with sodium hydroxide at 38 DEG B<\>ae, washed and dried.  In Example 7 the drying is performed on a loop drier and the fabric is then steamed with slight cross-stretching on a tenter frame.  The resin compositions in the examples are made up from the following ingredients:-poly - methylol melamine, hexamethylol melamine, ketone - aldehyde, a fatty carbamide, locust bean flour, tragacanth, triethanolamine glycollate, methyl cellulose, polyvinyl alcohol, ammonium chloride, ammonium thiocyanate, calcined soda, an alkyl phenol-ethylene oxide condensation product and dyestuffs.

The members 22, 23 are normally biassed by springs 30 so as to engage actuators 43 which can be caused to tilt by the depression of a selected push button 52 to cause a notch 51 to engage the upper edge of a common actuating plate 39, pivoted about an axis 40, 41. Depressing of the push button 52, also energises a motor 34, which drives a cam 36, through one revolution, the cam acting through a follower 38, to reciprocate plate 39, to drive member 22 through notch 51, to cause tappet 20 to move member 19, 'to tune the condenser 10. For remote control, the actuator 43 may be tilted by an electromagnet 79 energized by a switch 81, which also energizes the motor. In a modification, movement of the actuators may serve to switch in individual trimming condensers instead of adjusting a main condenser.
