Tipping-apparatus.-In a tippler comprising a cage-structure carried by end rings 1, a wagoncarrying carriage 9, 10 moves automatically during tipping between guide rails 12 to bring the top of the wagon against a supporting beam 19 carried by the frame, the wagon resting upon a tilting platform 6 pivoted out of centre at 7 in brackets on the carriage. The platform normally rests on fixed stops 28 and on horizontal surfaces at the top of fixed cams 17. When the tippler is turned in the direction of the arrow, rollers 16 on the platform 6 run down the cam tracks 17 until the wagon comes against the side support 18 on the carriage 9, 10. When the tippler has turned' through 90‹ the carriage moves between the rails 12, against the resistance of dashpots 25. The wagon is kept on the rails by engagement with the side support 18, and the top support 19 is movable in guides 21 on the tippler rings against the resistance of springs, not shown. The tippler may be driven by a motor 31 and gearing, and stops 30 on the rings and 16 on the fixed base limit its movement.

Title: Improvements in Machinery or Apparatus for Stripping Ingots.
IPC: B21J9/04
Filed: 1917-06-06
Abstract: 113,053. Atkinson, J. S., and Stein & Atkinson. June 6, 1917. Castings, extracting.-Relates to fluid-pressure apparatus for stripping ingots and consists in moving the stripping-plunger up to the ingot by one or more pilot cylinders, and then stripping the ingot by the combined action of the pilot and main cylinders. Figs. 1, 2 and 3 show an apparatus in which the mould 2 is supported on a framework 1 which also supports the working parts. The suction end of a pump 7, driven by an electromotor 8, is in communication, through a pipe 10, with a tank 9 containing a fluid, preferably oil or other thick fluid. The pump delivers this fluid under pressure by a pipe 11 to a distributing valve 12 controlled by a hand-lever. A safety-valve 16 communicates with the tank by a pipe 15, and the overflow from the valve 12 returns by pipes 19, 20 to the tank or the suction side of the pump. To strip an ingot, the stripping-plunger 6, carried by a cross-head 5 to which all the rams are connected, is moved up to the ingot by admitting fluid to the two pilot cylinders 3, and then the stripping is effected by admitting fluid to the main cylinder 4 also. The main cylinder communicates with the tank through a pipe 21 and a non-return valve, so that it is filled as its ram moves forwards with the rams of the pilot cylinders during their preparatory movement. The cylinders are all single-acting, and their rams are returned by a weight 23 hung on chains 24 attached to the crosshead 5.

Title: Automatic control apparatus
IPC: G05B19/4103
Filed: 1963-02-28
Abstract: 1,019,897. Programmed control of machine tools. GENERAL ELECTRIC CO. Feb. 28, 1983 [March 7, 1962(2)], No. 8096/63. Heading G3N. An automatic compensation system compensates for the effect of the thickness of a cutting element on a work-piece, in a system as disclosed in Specification 1,019,896, by modifying the path of a cutting element carrier in dependence at a rate directly proportional to a pulse train proportional to the desired resultant carrier velocity or to an independent pulse train. As shown, the velocity command pulse train for circular interpolation from command 29, each pulse of which represents an angular increment of rotation of a torch carrier 605, is fed to a command phase counter 901 wherein a clock pulse from a divider 28, selected from a flip-flop in the second decade, modulates the counter output due to the velocity command pulse train. The modulate train is compared in a phase discriminator 18<SP>1</SP> with the output of a resolver 905 driven by the torch carrier, suitably shaped by a shaper 911. A phase difference signal from the discriminator controls, through an amplifier 74<SP>1</SP>, a servomotor 75<SP>1</SP> coupled to the torch carrier. The resolver is fed from the divider 28 through a low-pass filter 62, a quadrature supply being derived via a phaseshift network. For an abrupt change in outward angle during linear interpolation the phase counter 901 is only fed from the divider with a clock pulse train, the angle T through which the torch carrier 605 rotates being determined by an angle T counter 919 set by the programme. An inside angle is cut by circular of a minimum radius determined by the diameter of the tool.

Title: Improvements in or relating to receivers for high frequency electric signals
IPC: H03D11/02
Filed: 1925-03-31
Abstract: 250,748. Brown, W. J., Burch, C. R., and Metropolitan-Vickers Electrical Co., Ltd. March 31, 1925. Thermionic amplifiers and detectors.-Relates to circuits of the type in which a " trigged " amplifying valve is set into self-oscillation by a received signal, and is periodically quenched by means of locally-generated oscillations, and consists in applying to the plate of the amplifying valve a source of alternating potential only. Simultaneously the grid is supplied with an alternating potential substantially equal to the plate voltage divided by the voltage factor of the valve, the grid and plate potentials being in phase opposition. Fig. 2 shows an arrangement in which the output from the amplifying valve 12 is not quantitatively proportional to the received signal. The valve is set on the threshold point by adjusting the reaction coils 23. 15 and the steady grid bias from the potentiometer 19. The plate voltage is derived from an alternator 20, whilst a tapping taken from a resistance 26 supplies the requisite alternating voltage to the grid 11. Fig. 4 shows a taper-regenerative receiver giving ,a quantitative response, suitable for telephonic reception. The alternating potentials required to supply the plate and grid voltages of the trigged valve 12 are generated by a second valve 37, fed by a high-tension battery 35 and retroactively coupled across a tuned circuit 31, 32. A blocking condenser 42 and choke 41 ensures that only the high-frequency oscillations generated in the circuit 31, 32 reach the plate of the valve 12, whilst an adjustable tapping from the inductance 31 supplies an oscillatory voltage to the grid 11.

Title: Improvements in or relating to soap
IPC: C11D17/04
Filed: 1961-03-09
Abstract: Filamentary growth is produced on the surface of water-containing soap objects, e.g. having the form of animals or human beings, by applying thereto a thin layer (preferably less than 2m  thick) of a sol, a suspension, or a gel, or a solution of a gel-forming substance, drying the layer, and then exposing the object to the air; it is preferred that the water content of the soap object be greater than 10% and that the soap consists partly of sodium oleate. Colloids which are suitable for direct application are (a) silicic acid in the form of a 4-8% gel suspension, (b) magnesium, aluminium, ferric, chromic or manganese hydroxides in the form of a 0,3-1,5% gel suspension, (c) silicates of these metals or of zinc in the form of a 0,3-0,6% gel suspension, (d) alginic acid or cellulose glycollic acid in the form of a 1-2% gel suspension, and (e) Prussian blue in the form of a 1,5-3% gel suspension.  Solutions of gelforming substances which are suitable are solutions of sodium aluminate, alginate and cellulose glycollate; objects which have been coated therewith are treated with carbon dioxide whereby the free colloidol substance is formed.  In a modification, the sol, suspension, or gel, or the solution of the gel-forming substance is incorporated in the body of the soap; under these conditions, the preferred amounts of the colloids above are (a) 6-10%, (b) 0,6-3% and (c) 0,3-1,5%.  Silica and iron, titanium and aluminium oxides in the form of aerogels are also suitable colloids for this embodiment.  The objects are preferably dried and exposed to air having a relative humidity 10-20% below that at which the soap neither increases nor decreases in weight, most suitably at a relative humidity of 70-80%.  If desired, the filamentary growth may be inhibited over selected areas of the objects to produce a patterned or decorative effect, by coating these areas with a 2-10% aqueous solution of polyvinyl alcohol or pyrrolidone, a polymethacrylate, gelatin, or varnishes containing nitrocellulose or chlorinated rubber.  The colourless filaments may be dyed, e.g. with petroleum ether solutions of eosin or Sudan red, and then either rendered insoluble by immersion in calcium or barium chloride solution, or fixed by spraying with an alcoholic solution of shellac or with an aqueous solution of polyvinyl alcohol.
Patent GB-250242-A (GB)
Title: Protective device for electric circuits
IPC: H02H9/02
Filed: 1926-03-31
Abstract: 250,242. British Thomson-Houston Co., Ltd., (Assignees of Compagnie Franþaise pour l' Exploitation des ProcÚdÚs Thomson- Houston). April 1, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Protective arrangements for alternating-current distribution systems employ a transformer having low magnetic leakage between its windings, its primary winding being energized responsively to the current in the protected circuit and its secondary winding being normally short-circuited through an excess current cut-out or other device which is open-circuited so as greatly to increase the inductance of the transformer when an excess current passes through it. The cut-out may be of the fusible or electromagnetic type or may be an electric discharge device such as a vacuum tube. A vacuum tube serves to introduce the high inductance, momentarily, in the event of transient atmospheric disturbances. A circuitbreaker in the secondary winding may be tripped by the closure of a relay energized by current or potential derived from the main circuit. The open-circuiting devices may be associated with means for resetting them with or without a timelag. Instead of open-circuiting the secondary, excess current therein may serve to start up an induction or other motor the resulting backelectromotive-force of which reduces the current in the secondary. The secondary may be connected either to the protected circuit or to earth.
