Title: Improvements in walking toys
IPC: A63H13/18
Filed: 1947-07-18
Abstract: 645,927. Walking toys. NICHOLLS, K. H. July 18, 1947, No. 1598/49. Divided out of 645,863.. [Class 132 (iii)] A walking toy comprises a body portion, a fixed limb member extending forwardly of the body portion, a freely mounted limb member pivotally attached to the body portion in such a position that when the figure is caused to rock on an inclined surface it progresses down the surface by rocking alternately on the two limb members, the freely mounted limb member swing- ing forwardly as the figure rocks forwardly on the fixed limb member and the fixed limb member swinging forwardly as the figure rocks rearwardly on the freely mounted limb member, and characterised by an extension on the freely mounted limb member shaped at its upper extremity to constitute a movable portion of the figure so that said movable portion oscillates relatively to the body portion during progression of the figure and simulates the natural movements of such body portion. The toy may be built up from sheet material or may be moulded in suitable plastics or metals. The extension on the freely mounted limb member may, in the case of a grotesque human figure, be shaped so..as to constitute the head. As shown, the toy may simulate a horse and jockey. The horse is provided with a fixed limb member 31 on which the forelegs are formed, the hind legs being formed on a freely mounted limb member 32 arranged in a slot 33 in the horse portion and pivoted at 34. Bases 36 and 37 are formed on the limb members, the operative surfaces of said bases being of arcuate shape, and that of 36 is covered with rubber to prevent slipping. The jockey's legs 41 are integral with the horse, the jockey's body 42 being an extension of the freely mounted limb member and protruding through the slot 33. As the freely mounted limb member swings the jockey's body oscillates relatively to the horse simulating natural movements. The forward swinging. movement of limb member 31 is limited by an adjustable abutment 43 screwed into a recess on the horse portion and projecting into slot 33. The rear face of the base 36 limits the forward swing of the limb 32. In addition an adjustable stop member 44 may be provided in the fixed limb member 31 to interfere with the periodicity of its oscillation. The toy may be used in race games such as are described in Specification 645,863.

Title: Improvements in the Metallurgy of Zinc.
Inventor: ARMSTRONG JOHN
IPC: C22B19/14
Filed: 1918-01-28
Abstract: 122,688. Armstrong, J. Jan. 28, 1918. Distilling zinc; briquetting processes; treating ores to remove volatile constituents.-In a continuous zinc-extraction process, the zinciferous ore or other material, intimately mixed with carbon, is fed into the upper section c of a retort comprising three sections, the said upper section being kept warm by being enclosed in a brickwork of the furnace. The smelting takes place in the middle section b of the retort which is enclosed in the combustion chamber a, the zinc vapour passing out through a branch f in the upper section to a condenser m in which a hood s floats in the metallic zinc and protects it and the fumes from oxidation. The residue from the sections b, which will contain in the metallic form any lead and iron originally present in the ore &c., passes into a third section d of the retort, from which it may be discharged periodically or continuously, admission of air to the retort being prevented. The middle section of the retort may be made of silica, corundum, or like refractory material, and the joint y between the first two sections and between the middle section and the brickwork, are enclosed and protected by the brickwork, a layer of jointing material u being provided in the latter case. The charge is prepared for the retort by comminuting the ore with bituminous coal, subjecting the mixture to a lowtemperature coking out of contact with air, expelling thereby the superfluous hydrocarbons and water vapour, and finally crushing the mass to powder.

Patent GB-397372-A (GB)
Title: Improvements in the winning of highly refractory carbides
IPC: C04B35/56
Filed: 1933-01-19
Abstract: Refractory carbides are obtained by heating to a sufficient temperature a body consisting at least partly of carbon in an atmosphere consisting of one or more volatile compounds of the element or elements whose carbides are to be produced so that carbide is formed with the carbon of the body.  The atmosphere may also contain reducing gases such as hydrogen.  The carbides of silicon, zirconium, hafnium, titanium, tantalum, vanadium, and the like may be thus obtained from their volatile halogen compounds.  According to an example a carbon filament is heated by the passage of electric current to a temperature of 2400 DEG  C. in a vessel containing vaporous zirconium chloride.  The process is continued until the resistance of the filament remains constant. The resulting zirconium carbide filament has the form of a tube. It is washed with water and alcohol.

Title: Improvements in or relating to the production of regenerated cellulose sheet wrapping materials
IPC: C08K5/136
Filed: 1945-01-24
Abstract: Flexible regenerated cellulose sheets or films are rendered resistant to mould-growth by incorporating in them a monohydric chlor- or brom-phenol of the benzene, toluene, xylene, or cymene series, or a salt of such a compound.  The films may be impregnated with an aqueous solution of the mould-inhibiting agent with or without glycerine or other softening agent for the regenerated cellulose and they may be treated during production while still in a gel state or they may be treated subsequently to the first drying.  As an alternative, the chlor-or brom-phenol may be incorporated in a coating composition, e.g. a moisture-proofing composition which is then applied over the surface of the regenerated cellulose film. Coating compositions having a basis of cellulose esters or ethers or synthetic resins may be used, e.g. a composition comprising a cellulose derivative, a gum or resin, a wax or wax-like substance, a plasticizer, and a chlor- or bromphenol, may be used.  In examples, a regenerated cellulose film in gel form is passed through a warm aqueous bath containing glycerine, and sodium pentachlorphenate or 2.4-dichlorphenol.  It is then dried by passage over heated rolls. In other examples, a transparent film of regenerated cellulose containing glycerine is passed through a moistureproofing and mould-inhibiting composition comprising cellulose nitrate, gum dammar, tricresyl phosphate, paraffin wax, 2.4.6 - trichlorphenol, toluene, ethyl alcohol, and n-butyl acetate, or with a similar composition containing 2.4.6-tribromphenol, or with a composition comprising cellulose nitrate, dicyclohexyl phthalate, gum dammar, paraffin wax, 1.3.6-o-chlorcresol, ethyl acetate, toluene, and ethyl alcohol. In other examples, regenerated cellulose film is coated with a composition comprising a vinyl chloride-vinyl acetate copolymer, tricresyl phosphate, paraffin wax, pentachlorphenol or o-chlorthymol and toluene.  Specifications 211,446 and 259,690, [both in Class 2 (ii)], are referred to.  The Provisional Specification describes also the incorporation of the chlor- or brom-phenol or salt thereof in the viscose from which the sheets or films are cast.

Title: Improvements relating to the deflecting of drill holes in diamond drilling
IPC: E21B7/08
Filed: 1963-01-17
Abstract: 1,025,092. Drilling details. SVENSKA DIAMANTBERGBORRNINGS A.B. Jan. 17, 1963 [Feb. 12, 1962], No. 2180/63. Heading B3C. [Also in Division E1] A device for deflecting drill holes in diamond drilling comprises a tube 1 whose bore axis is at an angle to its peripheral axis, a tube 2 having slots 4, connected to tube 1, and an expander 3 pinned to tube 2 at 7, and connected to a drill bit 5 by pin 56. In operation, the device is inserted into a hole whose bore is to be deflected. When tube 1 reaches the bottom of the hole, a first axial pressure is applied to bit 5 so as to shear off aluminium pins 7, thus releasing expander 3 from tube 2, and the latter is expanded against the hole wall. A higher axial pressure is applied to the bit, and pins 6 are sheared off, thus releasing the bit from expander 3, and the hole is drilled for a short distance in the required direction. The device is removed, and is replaced by a core drill to deepen the hole, and the hole is finally drilled with a core drill having a pilot.
Patent GB-1115493-A (GB)
Title: Amplifier system
Inventor: LOOFBOURROW ROBERT JAMES
IPC: H03M1/00
Filed: 1966-01-17
Abstract: 1,115,493. Analogue to digital converters. TEXACO DEVELOPMENT CORPORATION. 17 Jan., 1966, No. 2180/66. Heading G4H. In an analogue-to-digital converter the input signal is applied through an amplifying system providing a plurality of steps of amplification, the signal from one of the steps being selected and applied to an output circuit under the control of switching means actuated by the amplitude of signals from the various steps so that the signal applied to the converter is always maintained within a given range. The invention is applied in seismic exploration, the input signals being obtained from geophones 15, Fig. 1, registering the shock wave at different places resulting from a test explosion or the like. There are 43 geophones which are connected in turn, every millisecond to a single output lead 30 by multiplexing switches 29 operated by a 44 kc. clock pulse source 19. The last position produces a millisecond pulse which passes to a binary counter 35, Fig. 1a having 13 stages. These are connected to Or gates 70-82 so that each millisecond the count is recorded on the magnet tape 11. The geophone which, at any instant is connected to the lead 30 applies a signal to a chain of amplifiers 102, 107-112 each having a gain of eight. The output of each amplifier is passed to a comparator 128- 134 in which it is compared with a reference value representing the upper limit of the range of the converter 41. If the highest signal, i.e. that from amplifier 112 exceeds the maximum an output on one lead 152 blocks a gate 145 and a signal on another lead 153 opens the gate of the next amplifier. If this signal also exceeds the maximum the corresponding gate 144 is again blocked and the next gate opened and so on. The highest signal in the correct range is therefore selected by a corresponding switch 104, 115-121 and the actuating signal is also re-coded by diodes 170 to give a combinational signal on three leads 165-167 representing the amplification factor of the selected signal. The selected signal is applied to converter 41 through a buffer circuit 125 and converted to a ten-bit binary equivalent. This value is recorded with the amplification factor on the magnetic tape 11 when a delayed clock pulse on a lead 98 enables the recording amplifiers 93, 96, 175. The comparators are diode threshold circuits (Fig. 3, not shown) the signal on a lead (201) being compared with positive and negative limit values by diodes (207, 213). If either is exceeded a signal passes to an amplifier (217) to operate a Schmitt trigger (221, 222) producing the two gate controlling signals.
