Title: Installation for mechanically towing vessels on waterways
IPC: B63B21/56
Filed: 1924-07-01
Abstract: 240,246. M³ller, A. H. July 1, 1924. Addition to 218,652. Towing.-The towing-apparatus of the parent Specification is modified so that the yielding support of the tug automatically copes with slight variations in the vertical distance of the towing track above the boat whilst large differences are met by a separate mechanical adjustment. The tug 1, Fig. 1, on the track 2 is universally jointed at 4 to a carrier frame 5 which is universally jointed by a rotatable bracket 7 to the vessel 8. The. bracket 7 may be mounted on an adjustable support 16. The weight of the tug is balanced by a weight such as the electromotor 10 on an arm 12, the shaft of the motor transmitting power to the tug through a flexible shaft 17. The arm 12 is pivoted to the frame 5, its adjustment being varied by a turnbuckle 15 for meeting large differences in the track height. In order to minimize strains, a spring may be inserted in the linkage carrying the turnbuckle. In a further modification, the tug 1 is coupled to the bracket 7 by two pivoted arms 5, 6, the latter being controlled by links secured to a piston h<1> in a hydraulic cylinder i. By adjustment of the valves r<1>, q<1>, m<1> and use of the pump n' suitable positive adjustment of the tug position is effected. In the system, air chambers are provided for providing a pneumatic buffer to take up shocks.

Abstract: 1,094,336. Thyristors. SIEMENS-SCHUCKERTWERKE A.G. April 13, 1965 [April 29, 1964], No. 15842/65. Heading H1K. A thyristor consists of a PNPN structure with terminal electrodes 6, 5, to the outer P and Z zones 2, 4 and a control electrode 8 to one of the inner zones 3. The latter electrode is separated from the body of the semi-conductor by an insulating layer 7 and it covers at least part of the surface of the associated zone, extending over its whole length from one of its bounding PN junctions to the other. Fig. 1 depicts a switching circuit employing the outer N and P zones as emitter and collector respectively and with the inner N zone connected to the control electrode by way of the insulator. Both the insulator and the electrode plate overlying it extend somewhat beyond the bounding PN junctions of this zone. Fig. 2 (not shown) depicts a trapezoidal body, originally weakly N type, whose opposed plane surfaces have been made P type by diffusion and one of the P-zones subsequently provided with an N type fourth layer by alloying. The slant edges of the trapezoid have been oxidized and a control electrode, extending somewhat beyond the bounding junctions of the inner N zone, has been applied over it. The invention may also be applied to a planar device.

Title: Improvements relating to expanded synthetic resins
Inventor: ARMSTRONG ALMA PATRICIA
IPC: C08J9/02
Filed: 1953-06-12
Abstract: An expanded synthetic resin is made by polymerizing a phenol-formaldehyde casting resin with a foaming agent constituted by a diazonium salt as specified below, the water liberated in the curing of the resin reacting with the salt to form nitrogen which causes foaming of the resin, phenol which reacts with excess of formaldehyde, and an acid which aids the curing of the resin. The diazonium salts specified are benzene diazonium sulphate and phosphate, salts of the formula <FORM:0766066/IV(a)/1> where X represents any acidic radical and R1 and R2 represent, e.g., hydrogen, alkyl, aryl, hydroxy, alkoxy, acyloxy, nitro, amino, halogen, carboxylic acid or ester, or sulphonic acid grouping, and more highly substituted diazonium salts, preferably having at least one free ortho- or para-position; these salts must be comparatively pure and must be soluble in the casting resin. The casting resin used preferably has a viscosity from 40,000 to 70,000 cp.  A finely-divided filler, e.g. wood flour, cork flour, diatomaceous silica and mica, may be mixed with the resin, and also a wetting-agent in amount, e.g., of 0.05 mil. per 100 grams of resin. Curing agents specified, other than the diazonium salts, are benzene sulphonic, sulphuric, acetic, oxalic, and p-toluene sulphonic acids and metal chlorides.  Examples are given.

Abstract: 318,316. British Insulated Cables, Ltd., and Handley, W. C. June 6, 1928. Vacuum or low-pressure apparatus, arrangements of.-The circuit of a flashing or audible signal or the like is periodically closed by means of a relay operated by current impulses derived from a D.C. source through a neon lamp or like discharge device associated with a condenser connected to the D.C. source through a resistance. The supply source 3, 3<x> which may be a generator driven by a stream- or tide-driven water-wheel when the arrangement is applied to signal buoys in rivers or tidal estuaries, supplies current over the resistance 2 until the condenser 1 reaches a voltage equal to the flash-over voltage of the neon lamp 5 thus causing the condenser to discharge at intervals through the operating coil 6 of a relay. At each discharge, the contacts of the relay operate to close the circuit of the signalling device 11 which may comprise a lamp or horn or both. In a modification the relay operates the signalling circuit through a second relay associated with a dash-pot for increasing the period of energization of the signalling device by retarding the opening of the relay contacts. Means are also associated with the first relay for breaking the charging circuit of the condenser during the period of discharge through the neon lamp.
