Title: Electric power supply systems
IPC: H02H9/00
Filed: 1974-01-03
Abstract: 1441995 Electric protective systems DONET NI I PROEKTNO KONSTRUKKOT INST AVTOMATIZATSII GORNYKH MASHIN 3 Jan 1974 00168/74 Heading H2K A power supply system utilizing a transformer 1 and a rectifier arrangement 2 to provide a D.C. output has a controlled rectifier 59 arranged to short circuit the output terminals 48, 49 when the rate of change of load current exceeds a predetermined rate and to be returned to its non-conductive state when the rectifier arrangement 2 is de-energized by reset means 5 which is operative following triggering of the controlled rectifier 59. The transformer 1 has six secondary windings connected to respective rectifiers 16 to 21 having a common connection 47 to a voltage stabilizer 49 connected to output terminals 48, 49. The load 3 is connected to these terminals via a second thyristor 65, diodes 66, 67 and a choke 50 which is connected across one diagonal of a bridge comprising rectifiers 51 to 54 and resistors 55, 56. On change of current through the choke 50 above a predetermined rate the thyristor 59 is triggered and the voltage across thyristor 59 and diode 53 is insufficient to thyristor 65 and diodes 66, 67 conducting so that the load is isolated. With the full short circuit current, passing through a resistor 40 a signal is provided to a set of thyristors 22, 27 of the reset means 5 and the biased forward of these conduct to remove the output to the arrangement 2. With output from the arrangement 2 the thyristor 59 ceases to conduct and with no current through the resistor 40 the conducting ones of thyristors 22 to 27 cease to conduct as they become reverse biased. The output is thus restored to the load. The transformer 1 may have a further set of 3-phase secondary windings (Fig. 2, not shown) arranged to provide a limited output to the load whilst the main output is not available. The resistor 40 may be omitted if trigger circuit of the transistors of the reset unit is connected to the cathode of the short circuiting controlled rectifier.

Title: Method of producing acid-proof cementing mastics or puttys
IPC: C04B28/26
Filed: 1934-01-04
Abstract: Acid-proof cementing mastics comprising siliceous granules and a binder resulting from sodium silicate are made by subjecting fine quartz sand or like siliceous material, at moderate temperatures and pressures, to treatment with hydrofluoric acid or phosphoric acid, thereby activating the surface of the grains, and then mixing the treated material, without further additions, with sodium silicate which reacts with the activated surface of the grains.  In an example, quartz sand is treated with a 5 per cent solution of hydrofluoric acid at a temperature between 50 and 80 DEG  C. and under a pressure of three atmospheres.  The activated mass is mixed with soluble glass.

[Class 28 (ii).] In a slicing-machine wherein the substance is fed across a support by a substance-engager which consists of, or is adapted for use as, a pusher and is attached to a structure which is guided for movement transversely of the slicing plane of the knife, an auxiliary support is secured to the guided structure to reduce the frictional resistance to movement of the substance sliding over the main support, and the substance-engager is arranged so that it can occupy rear or forward positions in which it can act as a pusher or a clamp. As shown, the main support 5 has an upstanding wall 5<a> and the auxiliary support 6 has an upstanding wall 6<a>, the support 6 being secured to the guided feed structure which is operated by spring means as described in Specification 408,176.

A gutter is formed between the coaming 2 and the track 9 which prevents water from outside entering the hold. The tracks 9 have a downward slope 9<SP>2</SP>, Fig. 3, of such an extent that the wheels do not touch the track when the sections are closed, so ensuring the sections rest on the coaming. A loose cover section 15 is placed between the hinged cover parts and is fastened to the coaming, e.g. by bolts. The cover sections are of steel plate with longitudinal and cross ribs 7, 8, are provided with U members 20 forming a gutter for water which might penetrate between closed sections, and have their outer edges bent downwards as shown at 18 and 19. So that the cover section 15 will fall into its correct position, the coaming is provided with guide pieces 16 and the side ribs 7, of the section with guide pieces 17.
Patent GB-695202-A (GB)
Title: Improvements in or relating to processes for coating comminuted or granular materials with bituminous binders
IPC: C08L95/00
Filed: 1950-01-11
Abstract: Granular material is coated by mixing therewith a liquefied bituminous substance in the presence of an alkali metal silicate and a colloidal solution obtained by the complete hydrolytic decomposition of a protein.  The bitumen may be liquefied by dissolution, heating or emulsification.  Keratin is the preferred colloidal protein, and the amount of silicate preferred is 2 per cent. by weight of the keratin, the keratin itself amounting to 0.7 per cent. of the bitumen/keratin mixture.  When the bitumen is an emulsion, an acid medium is desirable especially an acid tanning agent, e.g. iron sulphate solution plus basic chromium salts, which simultaneously preserves the colloidal protein solution.  The sequence of mixing the different components may be varied.  The treated emulsion can be diluted with original emulsion and if solvents or solvent-containing substances, e.g. cut back bitumens, are also added, the breaking of the emulsion can be controlled. Heating also affects breaking of the emulsion. The protein colloid may itself be tanned and, as such, used to coat the aggregate.
