Title: Process and apparatus for the recovery of grease or fat
IPC: C11B11/00
Filed: 1923-09-18
Abstract: 204,326. Bailey, F. E. July 19, 1923, [Convention date]. Recovering fats from waste waters; purifying fats &c. - Grease is recovered by froth flotation from water used in scouring wool or boiling down mutton and beef tallow, by continuously circulating the liquor through a tank 1, pipes 12, 14, a centrifugal pump 15 and pipes 16 so as to produce a froth with air admitted through a pipe 26. Preferably air is also admitted at the bottom of the tank 1, and the liquor is agitated by propellers forcing it downwards on to a grid above a steam coil 8. The froth is transferred by slats 21 on a conveyer 2'0 to a vat 2 in which it is treated for about 2 hours at approximately 212‹ F. with a clarifying agent comprising , protein, potato, or other farinaceous substance, and sodium or potassium hydrate solution. The cleaned grease is transferred by the conveyer 20 to a vat 3 in which it is boiled until practically dry. The liquor may receive a preliminary cleansing by continuous circulation through a settling tank, the pump 15, part of the pipe 16, and a pipe leading to the tank. The froth may be broken or settled at any time by water from fine sprayers 23<a>. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use as purifying agent of potato &c. without alkali, and also of starch or any part of a potato. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to the production of olefins
IPC: C07C2/88
Filed: 1960-07-05
Abstract: In the production of olefins by growth of ethylene on a aluminium trialkyl having 2-8 carbon atoms per alkyl group followed by displacement <FORM:0904520/IV (b)/1> with a C2-C8 olefin, the displacement is effected in two stages, in one stage the aluminium trialkyl is displaced with a C3-C8 olefin and displaced olefins lower boiling (C12-) then the resultant aluminium trialkyl are separated by distillation overhead from the aluminium trialkyl, and in the other stage the aluminium trialkyl is displaced with ethylene to give aluminium triethyl which is separated by distillation with any lower boiling olefins overhead from C14+ olefins, the two stages being effected in either order.  In a preferred process ethylene from line 1 is reacted in growth reactor 4 with recycle and make-up aluminium triethyl from line 5 and recycle aluminium tributyl and trihexyl from line 6 at 160-350 DEG F., 500-5,000 p.s.i.a. for 0.2-10 hours with a mol ratio of ethylene to aluminium trialkyl of 0.5-20.  Excess ethylene is separated in drum 10 and recycled and a purge to remove ethane is taken from drum 13.  The aluminium trialkyl is displaced in reactor 16 with butene and hexene from line 17 at 60-400 DEG F., 10-1000 p.s.i.a. for 1/4 -12 hours using 4-20 mols of olefin per mol of aluminium alkyls.  Using liquid phase a catalyst may be added. e.g. nickel acetyl acetonate, colloidal nickel, Raney nickel or nickel sulphide on alumina.  Tower 19 is operated at 600-700 mm. Hg and 100-150 DEG F. to separate unreacted butene and hexene which are recycled.  If desired only hexene is liquefied and recycled by line 17, the butene being compressed, cooled, mixed with fresh butene in surge drum 42 and recycled by line 48.  The product leaves tower 19 as bottoms and is distilled in tower 27 at 40-50 mm. Hg. to separate C12- olefin product overhead.  Part, e.g. 75-95%, of the aluminium alkyls and higher olefins are recycled by line 6 and the remainder reacted in reactor 36 with ethylene from line 60 using the same conditions as reactor 16 but preferably conditions in which displaced butene and hexene are vaporous, e.g. 110-310 DEG F. 15-500 p.s.i.a. for 1-3 hours with 9-20 mols of ethylene per mol of aluminium alkyl. The overhead vapours are cooled to condense butene and hexene which are recycled via surge drum 42, and ethylene is recycled by line 59. Aluminium triethyl and C14 + olefins leave by line 50 and are distilled in tower 51 at 50-100 mm. Hg. and 200-275 DEG F. to remove aluminium triethyl overhead for recycle to line 5 and product C14 + olefins as bottoms.

Abstract: 917,503. Automatic frequency control systems. HUGHES AIRCRAFT CO. July 6, 1960 [Nov. 2, 1959], No. 23696/60. Class 40 (5). A variable-frequency oscillator 48 is controlled by a phase-locking A.F.C. loop, including a phase detector 46, to follow a variable input frequency at 10, but the latter may be switched out at 20 and substituted by a harmonics generator 28 energized by a stable lowfrequency oscillator # 1  so that the oscillator 48 is then locked in frequency with one of the harmonics of f 1  nearest to the input frequency. Moreover, the control loop is given a pass-band equal to f 1  so that one only harmonic is selected without ambiguity. The system may be applied to a Doppler radar tracking system. In a modification, the diode harmonics generator 28 is energized by the sum of an nth harmonic and the fundamental frequency of oscillator 22, the nth harmonic being obtained from a diode feeding a tuned amplifier, so that harmonics around the nth are increased in amplitude.

Abstract: 517,990. Closures for bottles. FIFER, Ltd., A., (Plympton, F. K.). Aug. 12, 1938, No. 23875. [Class 125 (iii)] A closure for bottles or other containers consists of a blank 1 of paper or other non-metallic material with one of its surfaces wholly or partly covered with a cohesive self-sealing compound 2. The blank is scored as indicated at 3 to facilitate the formation of overlapping pleats when the closure is in position on the bottle. Pressure is applied to the folded portions round the neck and the closure is held in place by the adhesive between the coated surfaces in contact with each other. Slits 13 may be made so that' the material will rupture easily when the closure is removed. The blank may consist of a number of plies of which the outer ply 14, Fig. 5, is of a moisture-resisting nature while another, 11, is adapted to receive the self-sealing compound 12. This compound may be a solution of rubber latex or a solution of rubber in benzole. The blanks may be made in strip form which may be fed by a machine to a forming position over the tops of bottles.

Title: Improvements in or relating to time base circuits
IPC: H03K4/86
Filed: 1939-08-18
Abstract: 536,215. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd. SHANNON, D. S. B., and CHATTERJEA, P. K. Aug. 18, 1939, No. 23883. [Class 40 (v)] In a time-base circuit in which a condenser Cl is discharged through a grid-controlled gas or vapour discharge valve V1, the effect of changes in the supply voltage on the charging time of the condenser is compensated by the use of diodes or other hard valves which control the potential of the grid of the valve V1, and so determine the instant of discharge. In the circuit shown in Fig. 3, the diodes V2, V3 form two arms of a bridge, the third arm comprising resistances R7, R12 in parallel and the fourth arm comprising resistances R8, R11. A fraction of the supply voltage is thus connected across two corners 2, 4 of the bridge, and the other corners 1, 3 are connected by a resistance R13 in the grid circuit of the valve. The diodes operate on the lower bend of their characteristic, so that when the current through the diode is small, a given change in current produces a much greater change in the voltage across the diode than when the current is large. In a modified circuit, Fig. 4 (not shown), a single diode in series with a resistance is connected across a variable part of the resistance in the grid circuit of the valve. In a further modification, Fig. 5 (not shown), the diode in series with two resistances is connected across the anode and cathode of the valve, the junction of the two resistances being connected through a condenser to the grid of the valve.
