Abstract: 531,492. Multi-track sound film apparatus. STEVENS, A. H. (Film Recording Corporation). July 24, 1939, No. 21472. [Class 40 (ii)] A multiple track sound film apparatus is provided with means for indicating both the lateral displacement of the recording or reproducing head determining a particular track and the travel cf the film determining the position of the head along the said track. In the apparatus shown, the film 11, Figs. 1 and 2 is driven by a sprocket wheel 6 on a shaft 4 fitted with a fly-wheel 5. The film is taken from a reel on bracket 15a to a reel on a bracket 14a. Normally, the take-up reel is driven by a belt 13a from a pulley 12a on the shaft 4. For winding the film back, the other reel is driven by a belt 16a from a pulley on the shaft or a roller 17a which is then brought by a lever 18a into frictional engagement with the fly-wheel 5. The film in its normal travel first passes through a dust removing device 13, then between guide rollers 12, and over the sprocket wheel 6, against which it is held by a pair of rollers 10. The rollers 10 are carried by a lever 9 normally held down by a spring 16 but capable of being lifted by means of a cam 14 with a handle 15. The length of travel of the film is indicated by a pointer 80 on a dial 75, the pointer being frictionally attached to a shaft 71, Fig. 6, geared by worm gear 73, 70 to a vertical spindle 61 itself geared by worm gear 65, 57 to the shaft 4. The recording head or the reproducing head 23 is mounted between horizontal pivots 22 on a carriage 20, which is mounted in a dove-tailed groove 18 allowing for adjustment transversely of the film. For this adjustment, a lever 33 is provided extending below the base 1 of the apparatus. The lever 33 is attached to a short vertical spindle 34 having a conical shape to take up wear. To the other end of the spindle is attached a short lever 36 with a spring 37 gripping between them a pin 38 on the carriage 20. The end of the lever 33 is bent up and fitted with a knob 40 carrying a spring pressed pin 41 co-operating with a set of holes 43 to hold the lever in its set position, the holes being marked with indicia indicating the corresponding longitudinal track of the film to which the recording or reproducing head is thus set. To lower and raise the head to engage and disengage the stylus from the film, the head is fitted with a finger 31 resting in a groove on an eccentric 29 adapted to be set by a handle 30. In a modification, the carriage of the recording or reproducing head is adjusted transversely by a screw and nut device set by a handle in relation to a dial.
Patent GB-536803-A (GB)
Title: Improvements in or relating to television and like systems and to scanning members therefor
IPC: H04N3/08
Filed: 1939-07-24
Abstract: 536,803. Television. SCOPHONY, Ltd., OKOLICSANYI, F., and GALE, A. J. July 24, 1939, No. 21506. [Class 40 (iii)] A television scanning member comprises a number of closely adjacent mirrors adapted to oscillate about parallel axes. Such a system reduces the moment of inertia of a scanner having a given dimension in the scanning direction. In one embodiment the mirrors 1, Fig. 1, are rectangular and are mounted so as to oscillate about their longitudinal axes 2, the spindles being mounted in bearing members 3b. Attached to the end of each spindle is a driving coil 4 arranged around a soft-iron core 6 and between magnetic poles 5. Oscillating currents of sawtooth or other desired form are supplied to the coils in parallel through individual variable resistances 7, these being provided in order that the amplitude of swing of the various mirrors may be independently adjusted. The angular motion of the mirrors is controlled either by employing a reduced end portion 17 of the spindles as a torsion spring or by employing opposed adjustable helical springs acting on a bar fixed transversely to each spindle, Fig. 2 (not shown). The driving of the mirrors may also be effected by longitudinal coils wound in slots in the spindle below each mirror, Fig. 6 (not shown). Alternatively mechanical oscillation by a suitably shaped cam may be used, all the mirrors being coupled together, Fig. 8 (not shown). For use as a high-speed scanner, the mirrors are either oscillated by torsional piezoelectric crystals, Fig. 10 (not shown), or are in the form of polished steel reeds vibrated in a constant magnetic field by a superimposed varying field, Fig. 9 (not shown). A complete scanning system employing the scanning member as a low-speed scanner comprises a light modulator 21, Fig. 3, a cylindrical lens 20 which focuses the light beam on a high-speed mirror drum 22 after reflection from which the rays are focused on the viewing screen 24 by a lens 23, frame scanning being produced by the scanning member of the invention 25 placed close to the lens 23. In place of the single lens 23 individual lenses for each mirror may be employed, Fig. 4 (not shown). The use of the invention as a high-speed scanner is described with reference to Fig. 12 (not shown). Specification 536,289 is referred to.

Patent GB-642828-A (GB)
Title: Convertible alkyd resins
IPC: C08G63/58
Filed: 1947-11-26
Abstract: Alkyd resins are prepared by reacting a dicarboxylic acid or anhydride thereof with a compound of general formula R-O-R1 in which R is an unsaturated group containing a double bond between two carbon atoms at least one of which is linked to a hydrogen atom, the carbon of the group which is linked directly to the ethereal oxygen atom being saturated, and R1 is glycerol minus one hydroxyl group or glycidol minus one hydroxyl group.  The products are made infusible and insoluble by heat and/or oxidation, catalysed by peroxides such as benzoyl peroxide, acetyl peroxide, and ascaridole, and lead, cobalt, or manganese linoleates, resinates, and naphthenates respectively. Gel formation during reaction may be prevented by diluting the reaction mixture with a hydrocarbon, e.g. kerosene. Specified are dicarboxylic acids: oxalic, malonic, succinic, glutoric, adipic, sebacic, maleic, isosuccinic, fumaric, phthalic, tetrahydrophthalic, terephthalic, naphthalene-dicarboxylic, diglycollic, dithioglycollic and dilactic acids; compounds of formula R-O-R1: glycerol or glycidol allyl-, methallyl-, 2-chlorallyl-, 3-chlorallyl, methyl vinyl carbinyl-, ethallyl-, ethyl vinyl carbinyl-, methyl isopropenyl carbinyl-, cyclohexyl-, cinnamyl-, 2-pentenyl-, 2-isohexenyl-, 2-dodecenyl, crotyl-, and 2-chlorocrotyl-mono-ethers, and less preferably, the 3-butenyl-, 4 - pentenyl-, 1,3 - dimethyl - 3 - butenyl-, 3 - pentenyl-, 5 - hexenyl-, oleyl-, 3 - phenyl - 3 - pentenyl-, linoleyl-, 3-pentenyl-4-cyclopentyl-, and 2 - isopropyl - 3 - butenyl mono-ethers of glycerol or glycidol, and more complex ethers of glycerol.  Examples describe reacting mixtures of phthalic anhydride and (1) and (2) glycerol allyl ether; (3) and (4) and (5) glycidol allyl ether.  The products may be used as coatings, which may be dried by infra-red heating, or as moulding compositions.  The initial condensation products, e.g. glycerol mono-allyl ether, mono- or di-phthalate, and an internal ester made by reacting oxalic acid with glycerol mono-ally ether, are capable of polymerization through the unsaturated groups.  The Specification as open to inspection under Sect. 91 comprises also the use of ethers of erythritol, pentaerythritol, xylitol, adonitol, arabitol, mannitol, sorbitol, perseitol, a - or b -methyl glycerol, beta-phenyl glycerol, a -methyl-b -ethyl glycerol.  This subject-matter does not appear in the Specification as accepted.
