Abstract: 941,889. Circuits employing bi-stable magrietic elements. SIEMENS & HALSKE A.G. March 7, 1961 [March 7, 1960], No. 8372/61. Heading H3B. In a cross-point matrix each column and row wire to which a pulse generator may selectively be connected is held at a potential equal to or greater than that of the pulse applied by the generator until such time as the channel is connected by completing its circuit to earth. The invention is applied to the coincident selection of a magnetic core in a storage matrix M, such as shown in Fig. 2, where the row and column wires are pulsed by a generator such as I connected in common to the row or column wires over rectifiers R. Each matrix wire is held at the pulse potential over resistors W until the wire is chosen for energization by switching a transistor Tx particular to the wire to connect it to earth at its far end. The wires may be switched from both ends (see Fig. 4, not shown). Where the row and column wires are not driven directly but over transformers U (as shown in Fig. 3), the primary windings are held at the pulse potential over resistors W and are gated by transistors Tx. The arrangement is said to isolate unselected row and column wires from disturbing voltage changes otherwise produced as the result of the capacity of the transistor gates.

Title: A method of reducing the tendency of petroleum oils to form stable emulsions with water
Inventor: MATTHEWS JOHN BRYANT
IPC: C10L1/16
Filed: 1954-03-24
Abstract: A method of reducing the tendency of a crude petroleum fuel oil or petroleum fuel oil to form stable emulsions with water, comprises altering the weight ratio of petroleum resins to asphaltenes in solution in an oil, which has originally a weight ratio of petroleum resins to asphaltenes of between 1:1 and 4:1, so that the ratio falls outside the range of 1:1 and 4:1. Petroleum resins are defined as being soluble in a mixture of n-octane and isooctane at 100 DEG C., and capable of being adsorbed on magnesia at 100 DEG C. from the resulting solution; asphaltenes are defined as being precipitated from petroleum oils when a mixture of n-octane and isooctane is added thereto at 100 DEG C., and which are soluble in hot benzene.  The ratio may be altered by adding sufficient petroleum resin or asphaltene to the oil to obtain a product having a ratio outside 1:1 and 4:1; or by blending the oil with an oil having a ratio between 1:1 and 4:1 to obtain a product having a ratio outside the range. The ratio may also be altered by contacting the oil with a solid adsorbent to adsorb sufficient petroleum resins from the oil to reduce the ratio to below 1:1. The adsorbent, which may be activated may be carbon, magnesia, bauxite, or adsorbent earths and clays, such as Fuller's earth, acid-treated clays, and bentonite clays, or a "synthetic zeolite" such as alumina-silicate and compounds of magnesia with silica.  The solid adsorbent may contain acid or alkaline materials, e.g. lime.  The oil may be treated with the adsorbent by percolation or contact filtration, or by adding the adsorbent to the oil as a powder.  In examples fuel oil products having ratios outside the range are obtained by adding to oils having ratios inside the range, an oil with a ratio outside the range, and petroleum resins obtained by extracting a petroleum fuel oil with iso-octane and distilling off the iso-octane.

Filed: 1954-03-24
Abstract: 757,440. Controllers. CAZZANIGA, C. A. March 24, 1954, No. 8590/54. Class 38(3) [Also in Group VIII] Relates to the control of a washing machine driven by a main electric motor P which is controlled by two pilot motors a and b. The pilot motor a drives a switchactuating cam shaft 3 whilst motor b drives two shafts 11, 12. To start operation of the machine, an indicating dial 4 is rotated so that cam disc 9 closes contacts o for the period of machine-operation, the motor b being energized through contacts i<SP>1</SP>, j<SP>1</SP>. When the disc i has been driven through a predetermined angle by the motor b, contacts i<SP>1</SP> are opened to stop the motor. In this position of the shaft 11, cam disc g opens a valve 17 to permit flow of liquid into the machine, and, as the liquid level rises, contacts I are opened and contacts n, n<SP>1</SP>, n<SP>2</SP>, closed to start the motor a and re-start the motor b which continues to rotate until contacts j<SP>1</SP> are opened by cams j. In this position, the water inlet valve closes, levers 13, 14 enter the "washing" position 16<SP>1</SP>, and contacts k' are closed to start the main motor. The connecting rod 13 is eccentrically coupled to a disc f and is coupled to the lever arm 14 for controlling the movements of washing and drying members of the machine. The pilot motor a continues to rotate, and; when contacts d are closed for a short period, the circuit for motor b is completed and maintained through contacts j<SP>1</SP> until the shafts 11, 12 have turned through predetermined angles. The cam h opens a drain valve 24, the lever 14 now occupying its dead-centre position 16, and contacts l<SP>1</SP> are closed to complete a main motor circuit for actuating a. discharge pump. The pilot motor a again closes the contactes d to turn the pilot motor b through a further predetermined angle, the lever 14 now taking the "drying'' position 16<SP>2</SP>, and the main motor being started through contacts m<SP>1</SP> and I provided that the machine has been emptied: The machine now passes through the drying cycle, with its drain valve open to permit discharge of the liquid centrifugally expelled from the articles being washed, said discharge being effected by means of a pump. The operation of the pilot motor a continues, whereupon cam 8 provides a further impulse for operation of the pilot motor b through an additional predetermined angle. The main motor stops when contacts m' are opened, the drain valve 24 being closed and the valve 17 opened, and, finally, the motor a stops when contacts c are opened by cam 5. In a modification, the cam discs 8 and i are replaced by discs 80 and y (Fig. 10). These discs co-operate. with contact arms 46, 48, which are. movable between fixed contacts 47<SP>1</SP>, 49<SP>2</SP>, and 47<SP>2</SP>, 49<SP>1</SP>, interconnected through strips 47, 49.

Title: Process for separating hydrogen sulphide and carbon disulphide from impure air containing them
IPC: B01D53/02
Filed: 1962-03-06
Abstract: In concurrently separating CS2 and H2S from air, e.g. the effluent from viscose processing plants, by passing said air through active carbon and then regenerating the carbon with steam (to remove CS2) and by extraction with CS2 (to remove S formed by oxidation of H2S) there is added to the impure air an amount of ammonia less than 0.02% by volume thereof. Where there is a lower content of H2S than CS2, and since the S is formed in a small zone of the active carbon, the carbon may be regenerated with respect to CS2 a number of times, e.g. up to 20 times, before regenerating with respect to sulphur.  Fig. 1 shows a system adapted for cyclic operation of the process in several beds of active carbon.  Contaminated air from line 12 is mixed with ammonia introduced at 14 and passed upwardly through bed 1.  In bed 2, CS2 is stripped from absorbent by first flushing with an inert gas to remove air and then passing in steam: the hot vapours are passed through a heating coil 23 to vaporize a solution of sulphur in CS2 obtained from a subsequent bed, cooled (coolers 25 and 26) and the water and CS2 separated.  The latter is employed subsequently to extract sulphur in <PICT:0966404/C1/1> S by means of recovered CS2 from reservoir 10; the CS2 may be introduced by means of an intermediate baffle only over the lower zone of the activated carbon. Sulphur is recovered from the extracted solution by passing into vaporizer 6 in which the CS2 is evaporated whilst the sulphur passes to melting apparatus 7 which is indirectly steam-heated.  In bed 5, bed 4. In bed 3 warm air or an inert gas from line 32 and heater 31 dries and cools the bed, which may then be re-employed for purification of air.  Bed 4 is undergoing extraction of CS2 used for extraction is removed as in bed 2 and thereafter the bed is dried similarly to bed 3. In Fig. 2 (not shown), heat from the vapours emerging from bed 2 is conveyed to the vaporizer 9 by means of a heat-exchanger liquid circulating between heater 23 and an exchanger in line 22.  The vapours pass from the exchanger to cooler 26.
