Title: Improvements in sorting or separating apparatus
IPC: B07B7/08
Filed: 1929-12-20
Abstract: 347,202. Centrifugal machines. WILKINS, E. T., H.M. Fuel Research Station, Blackwall Lane, East Greenwich, London. Dec. 20, 1929, No. 39029. [Class 23.] Mixtures of solid materials such as coal, coke, breeze, and ores, are separated by means of a member having a concave surface and rotating about a vertical axis, so that the mixture forms a number of zones on the surface. The constituent of each zone is separately removed. A pan 1, Fig. 1, has a central discharge passage 2 ; the material is fed on to it near the periphery and after its division into zones is removed by scrapers or other suitable means. The fraction which collects near the centre of the pan may be discharged through the passage 2. The pan may be divided, for instance, into three sections 3, 4, 5 as shown in Fig. 2. The annular members 3, 4 and the remaining part 5 may be rotated at the same or different speeds. Some of the separated material is projected over the outer edge of the section 3 or is removed by scrapers, and the portion which moves inwards from the section 3 undergoes further separation on the section 4. Some of this portion is projected over the upper edge of the section 4 into the section 7 of a second rotary pan 7. Similarly, another separation occurs on the section 5, and material is discharged into the section 8 ; the material which tends to accumulate near the axis is discharged through the passage 6 into the innermost section 10. The surfaces of the pans may have indentations or ribs, and may be formed of overlapping plates arranged so that the reaction between the surface and the material can be modified. Sweepers, or burnishers, or an air current may be used to keep the surfaces in condition, and the surfaces may be heated or cooled. The pan may be formed of radial overlapping and slightly flexible sections to permit of slight changes in the concavity.

Abstract: 944,972. Determination of the thickness of deposited monocrystalline layers. SIEMENS & HALSKE A.G. Oct. 17, 1962 [Oct.19, 1961], No.39248/62. Heading G1M. A method of determining the thickness of a monocrystalline layer of silicon or germanium deposited from the gaseous phase on to a heated parent crystal of silicon or germanium, comprises etching the surface of the deposited layer for a time such that a geometric figure produced by faulty crystal growth is made visible, measuring the length of a side of the geometric figure and calculating the thickness of the deposited layer from this measurement. Preferably a flaw-free (111) plane of the parent crystal is used for deposition and a flaw or flaws are made on this surface by touching it with a glass needle or by scratching with a glass needle. Alternatively a fine brush or a plug of cottonwool may be used to produce the flaws. The deposited layer develops from the produced flaws in the fan of equilateral triangles for a (111) plane. Other planes will give different geometrical figures. The surface of the deposited layer is etched with a mixture of chromic and hydrofluoric acids in aqueous solution so that the triangles become clearly visible. The side of the triangle is measured e.g. by a measuring microscope and the thickness of the deposited layer calculated by using an empirical formula.

At an operator's position, incoming calls are formed into a queue until a first predetermined number of calls are waiting whereafter further calls are prevented from joining the queue until the number of calls waiting therein has fallen to a second predetermined number. The disallowed calls may be diverted to a supervisor or to an announcement and/or recording machine or they may receive busy tone. If a call has been waiting an excessive amount of time, further entry to the queue-even though it is not full-can be prevented. A pair of contact ammeters CAA, CAB (Fig. 2) are connected to the lamp indicator-calling relay LR circuit of each incoming circuit. When the second (equal or lower) predetermined number of calls are waiting, the current through CAB is sufficient to close its contacts whereby relay RLB (Fig. 1) comes up. When the first predetermined number of calls are waiting, ammeter CAA's contacts close to energize RLA which then locks up. RLA brings up RLP in order to earth the P-wires of the other incoming circuits at this position. The appearance of the earth causes a selector to step on to another level where appropriate action is taken. When the number of calls waiting falls to the second predetermined number, CAB's contacts open to release RLB, RLA, RLP whereby new calls can be directed to this position. Ammeter CAB may be connected in place of contacts RLB1 thereby dispensing with relay RLB.
