Disc mills.-A continuously operating rotary apparatus of the kind in which the material traverses, in zig-zag fashion, coaxial rotating elements fitted with grinding devices, while being heated in vacuo or by hot air, is provided with an airtight charging device. The material, charged through an inlet 45, Fig. 2, into a stationary cylinder 5, is traversed by an archimedean screw 17 and drops through an outlet 18 into a rotary perforated cone 11. A pair ofgrinders 15, 16 grind the material as it passes from the cone into an outer rotating cylinder 10. A screw 14 takes the ground material together with the fines passing directly through the per forations in the cone to the discharge duct 19. The airtight charging device comprises a chamber 23, Fig. 3, formed between two fixed plates 21, 22. Plate 21 has two openings and plate 22 has one. Two plates 25, 26 with openings 32, 33 respectively and attached to a common hub 28 rotate on the plates 21, 22 so as to put chamber 23 in communication first with the atmosphere and then with the inside of the apparatus. Two small curved scrapers (not shown), carried by arms 36, 37, pile the material on the revolving plate 25 ready for dropping into the charging chamber when the openings in the plates 21, 25 coincide. Another scraper (not shown) operates in contact with plate 26. To regulate the grinders 15, 16, Fig. 2, two rollers 46 are mounted on axles radially arranged on a tripod 47. Arms 56 assist in breaking up the larger clots, and a screen 90 prevents the material from falling outside the crown 55. For heating the apparatus the cylinder 5 is fed with steam or hot water through a tube 6 and two hollow half shells 57 surrounding the movable part by a pipe 58. The material is discharged through an air-tight chamber 59 with valves 60, 61 controlled by compressed air. The drive of the rotatable elements is effected by teeth 69, Figs. 1 and 2, on the end plate 8 engaging a pinion driven by the main driving shaft 66. This shaft also drives a wheel 65 controlling cocks 62, 63, 64 for the discharging compartment, the archimedean screw and the charging device by means of an externally toothed crown 44. A handle 82 operates an uncoupling system to stop the feed of the apparatus at the end of an operation.

Abstract: 1,031,461. Automatic voltage regulators. JOSEPH LUCAS (INDUSTRIES) Ltd. Oct. 25,1962 [Nov. 1, 1961], No. 39064/61. Heading G3R. A voltage regulator for a generator includes a controlled rectifier of the type which can be switched off by a suitable pulse applied between its gate and anode terminals. As shown, a voltage regulator for a generator 1 having a field winding 5 and output terminals 2, 3 comprises a controlled rectifier 4 in series with the winding 5, a resistor 7 connected between terminal 2 and the gate of the rectifier, a pulse generator 12, preferably operable by the generator output, for supplying pulses to the gate of the rectifier, and a transistor 9 having its emitter connected to terminal 3, its base connected through a Zener diode 10 to a variable point on a resistor 11 bridging terminals 2, 3, and its collector connected over a diode 8 to the gate of the rectifier 4. When the output voltage is below a predetermined value, transistor 9 is non-conductive; the rectifier 4 is switched on by current flow through resistor 7 and is periodically switched off by the pulses from generator 12, the off periods being of short duration. When the output voltage exceeds the pre-determined value, Zener diode 10 breaks down to render transistor 9 conductive, whereby the current flowing through resistor 7 is divided between transistor 9 and the gate of the rectifier 4, the arrangement being such that the rectifier remains off until the output voltage falls below the pre-determined value.

Abstract: 993,425. Laminates. DUFAYLITE DEVELOPMENTS Ltd. Oct. 31, 1962 [Nov. 2, 1961; June 12, 1962], Nos. 39255/61 and 22539/62. Heading B5N. [Also in Division E1] A method of converting a slice of honeycomb material to the stably expanded state comprises pulling out the slice to the open cellular state, allowing it to contract in the direction of pulling between restraining members and thereby expand across said direction until it grips said restraining members, and simultaneously with or subsequent to the contraction securing facing material in cell closing relationship with the honeycomb material, thereby stabilizing it in the expanded state. In one embodiment (Fig. 1) a slice of honeycomb material 1 is expanded through a rectangular tube of strong kraft paper or cardboard, and after it appears beyond the end 4 of the tube is allowed to relax, hence contracting the direction of expansion by its natural resilience, until the accompanying transverse expansion causes it to grip the sides 5 of the tube. In another embodiment (Fig. 3) a sheet of cardboard or kraft paper 36, glued on its upper surface may be placed in the bottom of a jig. A slice of honeycomb material 31 is expanded to a width W<SP>1</SP>, positioned on the sheet 36 and allowed to contract until gripped by the retaining walls 35 of the jig, and is then covered by a covering sheet 37 glued on its underside. The process is repeated until the jig is full. The walls and base of the jig may be lined with kraft paper which is folded over the honeycomb on completion of the expansion process. The resulting material may be used in the construction of floors and concrete beams.

Abstract: 1473908 Casting processes FOSECO INTERNATIONAL Ltd 5 Sept 1975 [9 Sept 1974] 39331/74 Heading B3F A method of casting molten metal to form an ingot comprises locating in an ingot mould a substantially vertical tube 1 of fibrous material of melting point less than the casting temperature of the molten metal and which, under the action of the heat of the molten metal, forms a casting flux and mould wall coating, locating at or near one end of the tube a collar 2 of material which, under the action of the heat of the molten metal, disintegrates to form a cover of antipiping compound over the exposed molten metal surface at the termination of teeming, teeming molten metal into the mould to melt the tube and disintegrate the collar to form the cover of anti-piping compound, and allowing the molten metal to solidify in the mould. The tube and collar are held together by metal clips and the collar has location clips 3 for engaging the top of the walls of the ingot mould. In use, the molten metal may be top or bottom poured and, if top poured, is teemed through the tube to prevent splashing. The tube melts as the molten metal surface rises and forms the casting flux and mould wall coating and may consist of calcium or aluminium silicate fibres or glass fibres or impure materials such as rock or slag wool. The tube may be filled or bonded fibre and contain ingredients to enhance fluxing, generate a non-oxidising atmosphere, effect a fluidising of metallic oxides and aid the formation of a heat insulating layer on the top of the metal surface at the completion of turning. The collar 2 disintegrates on contact with the molten metal to form a layer of anti-piping material and consists of a heat-insulating refractory material, a heat-expandable material, such as expandable graphite, a fibrous material and a binding agent. In one example, the tube comprises, by weight, 10-60% calcium silicate fibre, 10-60% blast furnace slag, 5-20% fluorspar, 1-5% organic fibre and 4-7% binder, and the collar comprises, by weight 71% aluminium containing refractory materials, 3% oxidisable metal, 3% oxidising agent, 5% expandable graphite, 12% inorganic fibrous material, and 6% binding agent. The underside of the collar may have a heatreflective layer to prevent premature disintegration.

Abstract: 1,243,122. Frequency measuring. TESLA NARODNI PODNIK. 14 Aug., 1969, No. 40729/69. Heading G4H. In a digital frequency measuring system of the type in which a difference signal r (Fig. 5) is derived by a difference circuit 1 from a feedback frequency signal p and the input frequency signal n, the time intervals between pulses of the difference signal are measured, the reciprocals of these intervals being digitally derived in a circuit 3 and accumulated (additively or subtractively) in a circuit 4 controlling a pulse generator 5 delivering the feedback signal p. In the stable condition the state of circuit 4 represents the input. The time intervals between pulses may be determined by counting pulses of known frequency f 0 . A single order counting stage may be used, which when full alters the frequency f 0  by one order. The order of the frequency then determines in which order of the adding circuit the reciprocal of the counter value should be accumulated. If the distribution of the input pulses is not regular, scanning circuit (6, Fig. 6, not shown) may be connected between the input and the differentiating circuit 1 and, if required, between the output of the pulse generator 5 and the circuit 1.
