Title: Improvements in or relating to electric circuit arrangements for operating electric discharge lamps
IPC: H01F38/10
Filed: 1952-02-01
Abstract: 735,226. Supply systems for space discharge apparatus; automatic regulation; electric transformers. GENERAL ELECTRIC CO., Ltd., and CATES, J. Feb. 13, 1953 [Feb. 1, 1952], No. 2773/52. Classes 38 (2) and 38 (4). To reduce filament heating current variations due to supply voltage fluctuations and. to filament resistance variations, each filament heating secondary winding S1, S2 in an electric circuit arrangement for a heatable electrode discharge lamp L is divided into two seriesconnected voltage aiding portions of which one S11, S21 is wound on the same part of the core M as the primary winding P so as to be closely magnetically coupled thereto, while the other S12, S22 is wound on a different part of the core, whereby a magnetic leakage path or paths N1, N2 is introduced into its coupling with the primary winding; this arrangement is applicable only to circuits wherein for supplying the lamp discharge current there is either no secondary winding, or if one is provided it is closely magnetically coupled with the primary winding. The windings may be arranged on a core-type core in the manner shown in Fig. 2, or on a shell-type core with the high reactance secondary portions either on respective outer limbs or on the outer parts of the centre limb, the primary winding and closely coupled secondary portions being on the centre limb, in the centre thereof and separated by ferromagnetic shunts from the high reactance secondary portions in the latter case. The lamp may be a low-pressure mercury vapour fluorescent lamp and may have an earthed starting stripe E. A ballast choke B and a radio interference suppression capacitor C are provided.

Patent GB-600875-A (GB)
Title: Improvements in or relating to electrical toasting appliances
IPC: A47J37/08
Filed: 1945-10-26
Abstract: 600,875. Toasters. OVER, J. J. Oct. 26, 1945, No. 28321. [Class 28(i)] Bread slices placed in a frame 31 are depressed into toasting position between the heating elements 30 by manual depression of a vertical cylinder 20 and are held in this position by the lower end of. a pawl 27, pressed out by a spring 29, to engage the end of the frame. This depression of the cylinder also actuates the plunger 34 and its switch 33 to switch on the current. After the cylinder 20 is depressed towards its fixed piston 18, and on release of the cylinder the coil spring 21 begins to force it upwards so that air flows in slowly through the adjustable valve 24, the whole acting as a dashpot in co-operation with the piston 18. At the top of its rise the lower end of the cylinder 20 frees the pawl 27 so that its lower end pressed out by spring 29 releases the frame 31 so that the spring 15 raises the toast frame out of heating position. The time for toasting is adjustable by setting the valve 24 to the required release. The apparatus can also be actuated through an oil-dashpot arrangement with pressure oil passing from one side of the piston to the other through an adjustable leak valve. Since the cylinder 20 adjoins the heating element the rate of leak and toasting period will be compensated for in some degree in accordance with the heat applied to the toast. The apparatus may be designed to accommodate one or more slices of toast.
Patent GB-1000366-A (GB)
Title: Production of a limited stretch bulked plied yarn
IPC: D01H5/36
Filed: 1963-01-23
Abstract: Plied, bulked yarn having limited or zero stretch properties is made from two continuous filaments of heat-settable material one (a) of which has been highly bulked e.g. by stuffer or knife edge crimper, false-twister or air jet, permanently heat-set in the bulked state and then temporarily set in straight form and the other (b) permanently set in less highly bulked or straight form. Filament (a) is passed under minimum tension through a relaxing zone in which the filament or spaced portions thereof is/are heated to remove the temporary straight form and thus restore the bulked condition in which it is combined with filament (b) and the two filaments are intertwisted to form the yarn wherein the stretch property is determined by filament (b) and the bulk is due to filament (a).  A coating of bonding material e.g. wax or a thermoplastic pressure sensitive adhesive, may be applied to one filament prior to the plying operation and removed or retained thereafter.  In apparatus described, the filament a is overfed into and withdrawn from the relaxing zone by two pairs of feed rolls.  The forwarding effect of the entry pair is interrupted, at intervals predetermined by a programmer, by a solenoid-operated lever which swings one roller from nipping engagement with the other, Fig. 1 (not shown).  A modification comprises a variable speed device which, in a timed sequence determined by the programmer, changes the relative speeds of the pairs of rolls to control the position and amount of filament bulking which occurs in a heating tube in the zone, Fig. 4 (not shown).
