Title: Improvements in a method of and apparatus for classifying materials
IPC: B03B5/64
Filed: 1923-03-26
Abstract: 215,521. Arpin, J. B. March 26, 1923. Stationary-vessel wet-separating apparatus; washing-apparatus with screens.-A method of, and apparatus for, classifying materials consists in discharging the materials by means of a conveyer into a rotating sieve having different sizes of meshes, materials of a certain size being fed thence to a wet-separating apparatus. A conveyer 10, Fig. 1, feeds the material into a sieve 21 having different meshes, the finest being at the upper end. The finer grades of material pass through a removable funnel 25 to a shoot 26, whence a conveyer 29 delivers them to a spout 30. The coarsest material is delivered to a shoot 31 for re-grinding. The intermediate material passes through the coarse meshes to a hopper 32 provided with a stirring mechanism 34 for breaking up lumps and regulating delivery. The tank 33, Figs. 2 and 3, has an adjustable dividing board 35 of the contour shown. A conduit 42 is divided by a partition 45 having an adjustable vane 48 whereby the stream of water on either side of the partition and dividing board 35 may be regulated. A series of adjustable separating screens 60 - - 63 is provided, to each of which is attached a discharge shoot 100 - - 103 for discharging the materials separately. A series of posts 115 is mounted on the screen 63 to secure uniform change in the rate of flow of water. For varying the position of the screens 60 - - 63, two hand-wheels 94, interconnected by chains 90, are provided for each screen, so that rotation of either will, by means of the chains, raise each side of the screen uniformly. In operation, the flow of water due to the propeller 50<1> carries the materials from the board 35 on to the screens 60 - - 63, the lighter going to the screen 60 and the heavier to screen 63, from which they are washed to their respective discharge shoots. Materials escaping the screen 63 are caught in gratings 109<1>, 110<1>, whilst the heaviest material descends to a settling well, whence it is removed bv a screw conveyer 55 and conveyer 29 to a discharge shoot 30.
Patent GB-1332772-A (GB)
Title: Digital phase tracker
IPC: H03L7/00
Filed: 1972-02-24
Abstract: 1332772 Automatic phase control BENDIX CORP 24 Feb 1972 [31 March 1971] 8595/72 Heading H3A An automatic phase control system for phase locking two signals f 1 ,f 2  of the same frequency f comprises: a gating circuit 20 which is cyclically enabled and disabled by predetermined points on the signals respectively; a divide-by-n counter 24 counting cycles of the gating circuit 20, and generating a first output signal when n cycles have been counted; a clockpulse generator 18 generating a signal at a frequency nf; a divide-by-n<SP>2</SP> counter 27, 30 counting the number of clock pulses produced during n cycles of the gating circuit 20, and generating a second output signal when a predetermined count is reached : and a logic circuit to determine the number of clock pulses generated between the start of the first output signal, and the start of the second output signal to vary the phase of the signal f 2  accordingly. The two output signals are fed to respective monostables 32, 38, and if both occur at the same time, indicating phase lock, bi-stables 34, 39 are both inhibited, no output appears on t a  or t b  and no phase correction is made. This condition occurs when f 1 , f 2  are in antiphase. If the phase relation is such that an output occurs on t a  first, gate 50 is enabled and clock pulses pass directly to counter 30 which counts n/2 pulses and then produces an output on line 30a to trigger monostable 38 and terminate t a . During the time that t a  is being generated, gate 45 is open, gate 47 is closed, and every eighth pulse entered into counter 30 passes via gate 52 to output 48 to provide an "inhibit" signal which closes gate 14 thus retarding the output from divider 16. When t b  is generated, gate 45 closes and the inhibit signal is terminated. If the phase relation is such that t b  occurs first, gate 47 is enabled and every eighth pulse entering counter 30 now passes via gate 52 into counter 60. When t a  subsequently occurs, t b  is terminated and the trailing edge of it is differentiated by circuit 52 and applied to set bi-stable 54, the output from which provides an inhibit signal at terminal 48 which again retards the output from divider 16. In this case, the length of the delay is dependent on the number of pulses required to fill counter 60, and is, in effect, the same as advancing the phase of f 2 . The system may be used as a phase tracker in an Omega navigation system.

Title: Improvements in or relating to a process for the aluminothermic preparation of boron, borides and boron-containing alloys by reduction
IPC: C01G31/00
Filed: 1956-03-20
Abstract: Boron or borides are produced by aluminothermic reduction in a reaction charge containing an oxygen-containing boron compound, an oxygen-containing metal compound where a boride is to be produced, aluminium, and a scorifying agent which, in the quantity employed, is capable of combining with alumina and boric anhydride to form a complex slag readily soluble in mineral acid and/or caustic alkali. The scorifying agents referred to are the oxides of alkali metals and alkali earth metals and compounds derived from them such as the tungstates, molybdates and vanadates.  The invention may also be applied in partially removing oxygen from oxygen-containing boron compounds to obtain products containing 75 per cent or more of boron. The aluminium used for reduction may be replaced by an aluminium alloy such as calcium-aluminium, magnesium - aluminium or silicon - aluminium. <PICT:0794146/III/1> The amount of scorifying agent to be used may be determined from ternary diagrams of the slag components showing the areas of soluble slags, an example of which for the system B2O3:CaO:Al2O3, is shown on the Figure, the area C,m,d,e,f,g,h,i,j,k,l,a,n representing the area of readily soluble slags with the area of preferred compositions shown hatched.

Title: Method of delaying and reshaping pulses
IPC: H03K6/00
Filed: 1963-03-05
Abstract: 1,041,594. Transistor pulse reshaping circuits. HITACHI Ltd. March 5, 1963 [March 7, 1962], No. 8807/63. Heading H3T. In a pulse delay system comprising a delay line formed by a number of sections separated by switching-type reshaping amplifiers (Fig. 3, not shown), progressive width distortion is avoided by inverting the signal in at least one stage of successive amplifiers and by inverting retiming gates between other pairs of stages. As described, each amplifier comprises two inverting stages separated by an AND retiming gate (Fig. 8, not shown). Each stage may comprise a long tail transistor pair (Fig. 5, not shown) with the signal and a pedestal bias fed to one base and a reference voltage to the other. It is explained that due to the sloping sides of the pulses, drift in the reference level will vary the width of the output pulse but by ensuring that the input to the output stage is inverted with respect to the input to the next input stage the variation is cancelled. Invertion need not occur in every stage.
