Abstract: 881,622. Thermo-couples. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 23, 1959 [June 30, 1958], No. 20853/58. Class 37. In a method of making a thermo-couple or thermopile by successively vapour depositing films of suitable conductive materials and interposed insulating layers on a support to form a stack, each insulating layer is so formed that one end of the preceding conductive film is left exposed to form a thermo-junction with the succeeding film. In one arrangement shown in section in Fig. 3, a layer of aluminium 22, and successive layers of antimony 23, the insulator antimony trisulphide 24, bismuth 25, antimony trisulphide 26, and so on and a final layer 27 of aluminium are vapour deposited through masks on to a tapered base-plate 10 to form a thermopile probe. Several probes may be made sideby-side using a series of common or independent masks. The probe is clamped between massive brass terminal plates 13, 14 (Fig. 2) by insulated bolts 16. Where high sensitivity is required germanium is used in place of antimony or bismuth, in which case magnesium fluoride may be used for the insulating layers. As a further alternative the thermo-couple elements may be silver and iron or nickel. The base plate, which should be a poor heat conductor, may be of glass, silica, or an insulation coated or uncoated metal. In an arrangement described in the Provisional Specification, silver bonding layers are evaporated through masks on to the ends of conductors embedded in, or stuck or clamped to the surface of a glass or quartz rod, and are thickened, if necessary by electroplating. These layers are not essential when embedded conductors are used. Tapered strips of silver and nickel which overlap at their narrow ends to form a thermo-junction are formed by successive evaporations of silver and nickel through lacquer masks and overlap the ends of the conductors or the bonding layers. The latter should be of the same material as the respective strips if they are not thermally remote from the thermo-junction. Otherwise the bonding layers may be of silver and the conductors of copper or platinum. In an alternative construction a thermopile is formed by successive overlapping layers of nickel and silver on a flat insulating base through which terminal conductors of the same metals extend, alternate junctions being disposed at one edge of the base.

Abstract: 904,373. Boring earth. ECONOMIC FOUNDATIONS Ltd. Feb. 24, 1960 [June 17, 1959], No. 20885/59. Class 85. Feed pressure is applied to a kelly bar by a member which rotates with the kelly and has at least two members operable to grip or release kelly on opposite sides thereof, means being provided to apply downward thrust to the rotating member and thus to the kelly. In Fig. 4, a plate 17 having a square central hole to fit the kelly 18 is secured to a lower circular plate 21 having a spacing flange 22 which forms an annular recess for slippers 15 which support the plates 17, 21 from a stationary ring 14. The ring is carried by hydraulic rams 12 which raise the plates on the kelly and then reverse to pull the kelly down. The thrust is transferred from the plate 17 to the kelly by toggles 24 comprising plates which are accommodated in recesses between the plates 17, 21 or in inserts 25 in those recesses. The toggles 24 are shaped to embrace the square kelly and have lateral extensions which are engaged at diametrically opposed points by two means, each comprising spaced abutments 33, 34 on a rod 30 slidable in the plate 17 and having a spring 32 adjustable by a nut 31. The springs tend to keep the edges 27 of the toggles in operation against the kelly. When the plates 17, 21 are raised by the rams 12, heads on the rods 30 strike a stationary framework 36, the abutments 33, 34 being depressed to disengage the toggles 24 from the kelly. When the rams 12 again descend, the heads are released and the springs 32 bring the toggles into action.

Abstract: 657,054. Automatic control systems for telegraphy. WESTERN ELECTRIC CO., Inc. Aug. 1, 1947, No. 20991. Convention date, July 6, 1945. [Class 38 (iv)] [Also in Groups XL (a) and XL (b)] A cathode-ray tube comprises a number of targets which are selectively hit by deflection of the beam, and a number of auxiliary target electrodes, which are arranged with respect to the targets and are connected to the deflecting means whereby accidental impingement of the beam thereon will deflect it on to the selected target. The invention may be applied to the high-speed time-modulated signal receiver which, as described in Specification 657,053, comprises a cathode-ray tube in which the beam scans a circle, concentric with stencil cuts in a metal or insulating screen 340, and is radially deflected each scan by the signal on concentric electrodes 330 across the appropriate stencil cut to reproduce the cipher on a fluorescent screen.. Manual and automatic adjustments to retard or. advance the scanning potentials on the deflecting system 322 is achieved by phase shifters 240, 250. The variable condensers 244, 245 can be operated by the knob 241 until the predetermined transmitted synchronizing signal is received, e.g. the letter I, when the beam will impinge on a surrounding electrode 344 to operate an electromagnetic clutch 246 arranged between the knob and the condensers. Accurate impingement of the beam on the appropriate stencil cut is ensured during operation by auxiliary electrodes 345, 346 connected to windings 258, 259. Wandering of the beam on to the auxiliary electrodes will cause a correcting signal in the phase shifter 250 which comprises resistances 252, 253 and inductances 254, 255. Further windings 257 are used to adjust the initial values of the inductances. The scanning beam may have a circular cross-section and may be deflected in a curved path across the stencil cuts.

Title: Resinous condensation products and laminates prepared therewith
IPC: C08G77/46
Filed: 1960-06-16
Abstract: A co-condensate is made by heating a substantially anhydrous mixture comprising, by weight, 50-96% of a phenol-formaldehyde resole, 30-2% of a silane or siloxane having one of the formulae: <FORM:0951065/C3/1> and <FORM:0951065/C3/2> wherein R is an alkyl group having 1 to 4 C atoms, R1 is an aryl radical and each R2 is an alkyl or alkoxy radical of 1 to 4 C atoms or an aryl radical, and n is 0, 1 or 2, and 20-2% of glycidyl polyether having an epoxide equivalent of at least 170, the epoxy resin being introduced initially or after reaction of the other materials, and removing the liberated alkanol.  The reaction may be effected by heating the reactants to reflux temperature and removing the alkanol formed, but is preferably effected under reduced pressure.  When making the co-condensate it is preferred to add a little polycarboxylic acid or anhydride, e.g. mellitic, chlorendic, phthalic, terephthalic and adipic acids or anhydrides, the dianhydride of pyromellitic acid being preferred. The products are preferably diluted to 40-70% (wt.) of resin solids with an anhydrous low-boiling acyclic mono- or poly-hydric alcohol of 1-4 C atoms, e.g. ethanol, n-propanol, isopropanol or ethylene glycol.  The resoles and organosilicon reactants used are well known, and the epoxy resins used are those obtained by reacting epichlorohydrin with a phenol or a polyhydric alcohol, e.g. as described in U.S.A. Specification 2,640,037.  In a typical example (1), a glycidyl polyether of bisphenol A is added to the reaction product of phenol, paraformaldehyde and hexamethylenetetramine and the mixture is heated under reduced pressure; phenyltrimethoxysilane is then added and the mixture is again heated under reduced pressure with removal of methanol by distillation, cooled and mixed with isopropanol to provide a solution containing 60% (wt.) of resin solids.

Abstract: 1,068,474. Automatic steering control. DANSK AUTOMATISK ROR-KONTROL AS. May 22, 1964 [May 25, 1963], No. 21323/64. Heading G3R. In an automatic steering control system for a ship, an electrical network connected to the pick-off of a compass, arranged outside the wheelhouse, has a distribution of potential indicative of the course of the ship and adjustable pick-off means connected to a rudder controller. As shown, alternating voltage from an oscillator 33 is applied between electrodes 19, 20 carried by the float of a magnetic compass so that the relative phases of the potentials of electrodes 26-29 located in the conductive compass liquid are dependent on the heading of a ship carrying the compass. The potentials of electrodes 26-29 are applied through cathode follower stages 46-49 to a circular resistance element 34 having sliders 40, 41 which are set to correspond with a desired course. Deviations in one sense or other from the desired course then produces a voltage of one phase sense or the other which is applied through a de-modulator 42 to correct the heading by servomotor control of the rudder (not shown). Course setting resistor 34 may be located in the wheelhouse while the compass is kept in a more suitable location and viewed through a periscope. Additional shunt resistors 44 may be associated with resistor 34 to compensate for non-linearities in the compass potential distribution. Each pair of potentials applied to resistor 34 serves to energize through de-modulators 50, 51 one coil of a two-coil moving coil course indicator 52. The arrangement of compass elements and the method of supplying current to them is illustrated in Fig. 1 (not shown). Use of circular resistor or light responsive compass pick-offs instead of the conductive liquid arrangement is referred to.
