Title: Improvements in or relating to crystallising varnishes
IPC: C09D167/08
Filed: 1930-04-09
Abstract: A crystallizing varnish is made by dissolving in a hydrocarbon solvent a synthetic resin of the polyhydric-alcohol-polybasic-acid type which has been modified with fatty acids or colophony, and incorporating bodied China wood oil with the solution.  Driers may be added, and the varnish may be thinned with high-boiling gasoline, "mineral thinner," "petroleum distillate," or "turpentine substitute."  Pigments may be added.  The modified resins are preferably prepared with drying-oil acids, e.g. the acids of chinawood oil or of linseed oil.  The hydrocarbon solvent may be aromatic, aliphatic, or a mixture, e.g. toluene, solvent naphtha, or a mixture of solvent naphtha and high-boiling gasoline.  The bodied China wood oil is preferably the blown oil, but the heat-treated oil may be used.  The proportion of modified resin to blown oil may be between 1 to 1\ba1/2\be, and 1 to 2\ba1/2\be.  Suitable driers are cobalt-linoleate in turpentine (0.75 per cent cobalt), and a manganese drier in turpentine (1,5 per cent manganese).  The modified resin is usually cut hot with the solvent, mixed with the oil and drier while hot, and cut with the thinner.  The varnish may be heated at 150 DEG -200 DEG  C. to accelerate mixing.  In examples, the modified resin is prepared from glycerol, phthalic anhydride and either China wood oil acids, linseed oil acids, or resins.  Coating processes.--The varnish is applied as a film, heated gently, e.g. to 60-70 DEG  C., to produce a frosted pattern, and then baked, e.g. at 100-150 DEG  C.

Title: An improvement in or relating to sluice gates
IPC: E02B7/20
Filed: 1926-04-30
Abstract: 271,233. Blakeborough, R. A., and Klouman, F. A. April 30, 1926. Sluice gates.-In mechanism for operating a sluice-gate so as to control the flow of water to maintain a constant level in a conduit served by the gate, a level is pivoted at one end to a float arranged to rise and float with the water of which the level is to be maintained and at the other end it moves controlling the operation of a prime mover for actuating the gate, and is mounted pivotally at a point between its ends on a block forming a nut through which passes a screw connected by gearing to the gate operating means. The gate a in the conduit b is operated by a rope c wound on drums d on a shaft e rotated by an electric motor g. A float i is located in a chamber h which communicates with the conduit b. The float is secured to a rod pivoted at its upper end to a level l, the other end of which is pivoted to a rod m adapted to operate a reversing switch n controlling the motor g. Between its ends the lever l is pivoted to a block o forming a nut on a screw p which is rotated from the shaft e through gearing r, s. When the water level is normal, the switch n is in the neutral position. If the level falls, the lever ! l is rocked about its central pivot by the fall of the float, and operates the switch to cause the motor to open the gate. The screw p is thus rotated, and the nut o moved in such a direction as to cause the end of the lever l connected to the switch to be moved back to its original position and the switch to be restored to the neutral position. As the water level rises, the float i rises, and the lever l pivots so as to bring the switch n into such a position as to cause the motor to close the gate. The consequent movement of the screw moves the block towards its original position. By a series of movements of the gate, the water level and the position of the gate are finally brought back to the original normal position.

Title: Improvements in or relating to electric signal transmission systems
IPC: H04B3/10
Filed: 1939-04-14
Abstract: 527,564. Repeating systems. STANDARD TELEPHONES & CABLES, Ltd. April 14, 1939, No. 11431. Convention date, April 22, 1938. [Class 40 (iv)] In an arrangement for substituting a spare amplifier for a normal amplifier in a signal transmission system while the latter is tested, means are provided for bringing the two amplifiers to the same gain adjustment before the switch over is effected. The invention is particularly applicable to a broad band system in which the amplifiers are provided with automatic gain regulation under the control of a pilot frequency. As shown in Fig. 4, the normal amplifier is connected in the line by cords 17, 18, while the spare amplifier 2 is connected to contacts of a two-way switch 19. A variable loss device 5, normally set at zero loss, is shunted by the cord 17, and the outgoing line is bridged by a high impedance pad 6. On the removal of the cords 17, 18, the circuit is as shown in Fig. 2, and the spare amplifier 2 on account of its high impedance input adjusts itself for maximum gain. The loss of the device 5 is now increased until the normal amplifier 1 is also set for maximum gain, which is indicated by the fact that any further increase reduces the reading of a pilot voltmeter 27 connected across the output. On the operation of the switch 19, the circuit is as shown in Fig. 3, and the normal amplifier 1 may be tested without affecting the transmission. The normal amplifier is replaced by reversal of the process.

Abstract: 1,097,123. Semiconductor strain gauges. ETHER ENGINEERING Ltd. March 15, 1965 [March 18, 1964], No. 11522/64. Heading H1K. [Also in Division G1] A strain gauge element has a plurality of integral elongate strain members extending from a common point and each of which in use is bent about an axis transverse to its length by a load applied to the common point by a diaphragm or a seismic mass. Each strain member is shaped so that along at least part of its length at least one of its transverse dimensions decreases with increasing distance from the common point. This tends to even out the strain applied to a transducer element bonded to the surface of the member or formed by diffusion of impurities into (silicon) semiconductor members. The gauges described are of two types. These are those having elongate members of uniform width but of varying depth and comparable devices in which the elongate members are of uniform depth but of varying width. The uniform device shown falls in the latter category. Transducers 19, 27 on the upper surface have counterparts on the lower surface. With all the gauges the transducing element may be connected in bridge circuits.

Title: Improvements in and relating to strapping material for binding or securing boxes, bales, parcels and other packages and process for manufacturing said improved strappingmaterial
IPC: C23F1/00
Filed: 1936-04-24
Abstract: Steel strapping material for use in strapping or tying packing - cases, parcels, bales, &c. is subjected, without the application of heat, to a reagent capable of effecting a chemical reaction therewith to produce a rough or granulated surface so that the coefficient of friction of all the surfaces thereof which coact to form the joint is increased.  The treatment may be a chemical transformation of the surface, for example passivation by concentrated nitric acid or a short treatment, e.g. for 1 minute, in dilute nitric acid, or it may be an electrolytic treatment by which a certain proportion of one or more constituents of the surface is removed.  For example the steel strapping material may be made the anode in a bath consisting of a solution of ferrous ammonium sulphate and ferrous carbonate in water, some of the iron of the material being thereby transferred to the cathode. When the chemical treatment is used any compound formed on the surface of the material may, if desired, be removed after the treatment.  The strapping material may be in the form of flat, round, or non-round wire, band, or strip and in treating short lengths the two ends which coact to form the joint only need be roughened.  The material must have been formed by cold working and must not have been annealed, hardened, or hardened and tempered prior to the roughening. Specification 471,545 is referred to.
