Title: Improvements in means for electric welding
IPC: B23K9/10
Filed: 1937-12-17
Abstract: 507,843. Control systems for welding arcs. ENGLISH ELECTRIC CO. Ltd., CHADWICK, A. T., BERTLES, E. J., and WHITE, J. S. Dec. 17, 1937, No. 34975. [Class 38 (iv)] In electric welding apparatus of the kind wherein the potential of an electrode holder or equivalent part is reduced when welding is not actually in progress and is raised automatically in response to welding contact, a contactor operating coil 3 in parallel with the electrode 4 is substantially short circuited and de-energized whereby it closes its contacts 3a when the welding circuit is completed through the work 5. Welding current is drawn from one end of the secondary 1a of a transformer 1 the other end of which is earthed, the low potential for the welding electrode 4 being taken from a tapping 1b. The high potential end of the secondary and the tapping 1b are connected by a circuit including a current limiting resistance 2, the usual regulating choke 6 and the contactor contacts 3a which are closed when th coil 3 is de-energized. In the example the electrode 4 and one end of coil 3 are connected to the high potential end of resistance 2, the work and the other end of coil 3 being earthed. When the supply is switched on, coil 3 is energized and contacts 3a open immediately, but the coil remains energized due to the connection to the lower voltage tapping 1b, so that the contacts remain open. The electrode 4 is at low potential until brought into contact with the work 5, whereupon the coil 3 is short-circuited and the contacts 3a close. The full voltage of the secondary 1a is then available for welding. The contactor may be biassed to the closed position by a spring or gravity, and is preferably provided with a time-lag device for delaying the opening of its contacts after the breaking of the arc. The contactor may be operated by a D.C. coil fed through rectifiers, the time lag then being produced, at least in part, by shortcircuited secondary coils on the contactor for increasing artificially the time constant of the operating-coil.

Abstract: 1319203 Cathode-ray tubes INTERNATIONAL BUSINESS MACHINES CORP 27 July 1971 [29 Oct 1970] 35062/71 Heading H1D [Also in Division H4] An electrostatically deformable member 40, suitable for use in a Schlieren optical system for example, comprises a deformable dielectric solid layer 42, e.g. of silicone rubber, in intimate contact on one side with a rigid dielectric substrate 41 and on the other side with a deformable conductive material 43. In one mode of use the member is placed within a cathode-ray tube adjacent the faceplate 11 thereof, substrate 41 being of mica which may be coated with SiO, SiO 2 , MgO or MgF 2  to enhance its resistivity, so that a first electron gun may provide an electrostatic pattern 44, 45 thereon. It is said that point charges and uniformly charged areas both produce a unidirectional deflection of material 43 towards the charged areas, whereas in former devices wherein the conductor 43 was rigid and deposited on plate 11 away from layer 42 they produced oppositely directed deflections. A second "flood" electron gun is provided to erase the charge pattern, or the first gun may provide both functions. The member 40 may be light transmissive (43 is Au or Al) or reflective (43 is Ag or Al). In a further embodiment, Fig. 5 (not shown), a further layer of conductive material is laid down on the exposed face of substrate 41 (mica or glass), one or both the conducting layers being in the form of parallel strips, radial or alpha-numeric patterns for example and selected areas are addressed in or out of a vacuum to selectively deform layers 42, 43.

[Class 35] [Also in Group XXVII] Engine speed and intake-manifold pressure are both used to vary the timing of a magnetogenerator. The engine-driven shaft 25 is slidably mounted within the supports 5, 6 of the rotor 2. Helical splines 29 on the shaft 25 and straight splines in the support 5 are engaged by an intermediate sleeve 32, the position of which is adjusted by a centrifugal governor 43. A bellows 35 responsive to engine-intake suction, exerted through a conduit 41, acts through members 37, 38 on the end of the shaft 25. The springs 42 tend to maintain the shaft in a medial position. The interrupter 16, 17 for the primary circuit is secured to the rotor support 6 and the distributer rotor 19 driven through gearing 23, 24.

Title: Manufacture of dispersible phenothiazine compositions
Inventor: ZABA JAROSLAV BOGUMIL JAN
Filed: 1953-12-18
Abstract: A process for the manufacture of a dispersible phenothiazine powder comprises spray-drying a solution containing phenothiazine and a surface-active agent.  As solvents those boiling below 100 DEG  C. and liquefied gases, such as acetone, trichloroethylene, liquid anhydrous ammonia and sulphur dioxide are specified.  The surface-active agent may be nonionic, such as the condensation product of ethylene oxide with alkylated phenols or with long-chain fatty alcohols.  After the drying the powder may be recovered in a cyclone and the solvent recovered.  Examples (illustrating the use of the condensation products of ethylene oxide with octyl-cresol and sperm oil alcohols, respectively) are given, the products being wettable and giving a flocculated suspension in water.

[Class 42 (ii)] Cuttling and folding transversely.-When the last laid fold of fabric is freed by the gripper 20 and its tension therefore relieved a feeler 31 contacting with the end of the fold closes one or other circuit 33, 34 if the fold length is above or below its proper length and through electric, pneumatic, hydraulic, or mechanical means correspondingly adjusts the travel of the folding spade &c. 10. As shown in Fig. 1, the spade 10 is pivoted to a slide 11 which is reciprocated by a band 9, wheel and rack 5, 3 and crank 2 on the main shaft 1. The spade slides on and is tilted by a rod 14, the pivot 13 of which is raised and lowered by a sector and worm 24, 26 and a motor 27 controlled by the feeler 31. The motor circuit can only be closed when a cam 43 on the main shaft 1 closes the contacts 41, 42, which occurs when the gripper 20 has been raised. The travel of the spade may be otherwise varied e.g. by automatically adjusting the throw of the crank 2. The frame 49 carrying the contacts 33, 34 is adjustable to give different lengths of folds of fabric. The contacts 33, 34 may be carried by a lever 54, Fig. 4, and connected with a roller 59, so as to be adjusted automatically according to the thickness of the fabric being g folded. The table 21, Fig. 6, may be lowered as the pile of fabric 22 thereon increases by means of a motor geared to the table post and controlled by contacts such as 93, 113 connected with the gripper 20, or as shown in this Figure, the gripper 20 may control two sets of contacts 93, 114 connected with a reversing motor 118 which adjusts an arm 128. A blade 129 on this arm allows a pawl 124 on an arm constantly oscillated by an excentric 122 on the main shaft 121 to engage for a longer or shorter period a ratchet wheel 125 geared to the table post 127.
