Filed: 1975-08-28
Abstract: 1507324 Electrolytic sterilization and decontamination of liquids SACHS SYSTEMTECHNIK GmbH 28 Aug 1975 [3 Sept 1974] 35604/75 Heading C7B The process comprises anodically oxidizing the contaminated liquid e.g. germ containing water in the presence of Ag ions added thereto before or directly after entry to the electrolytic oxidizing cell in a quantity which is adjustable independently of the electric oxidation conditions the oxidation anode being insoluble, and the quantity of Ag and magnitude of the oxidizing current being jointly selected to effect decontamination. Electrolytic dissolution of an Ag anode or an added Ag compound may provide the Ag ions. In Fig. 5 the  liquid enter cathode chamber 54 of oxidizing cell 51, the diaphragm 513 advantageously being cation impermeable. Cell 522 has Ag anode 511 which is electrolytically dissolved. Ag-bearing liquid is oxidized in anode chamber 55 and exits through the throughflow cathode 527 of cell 522 for Ag recovery. This cathode may be of sintered metal, metal wool or graphite on plastic. Diaphragm 523 is cation impermeable. Variations disclosed include; (a) integration of the Ag-supplying cell and main cell by putting both cells in a common housing; (b) diaphragm absent from either or both cells; (c) no passing of the liquid either first through the cathode compartment and/or subsequently through a recovery cell; (d) partial recycle of liquid between anode and cathode compartments by using a screen at 513 and provision of a conduit circuit; (e) passage of only part of the liquid via the Ag cell with recombination of the streams before oxidation; and (f) provision of bi-polar electrodes parallel with, separated by and supported on insulating spacers between the main cell electrodes. The main and bi-polar electrodes may be of CrNiMo-steel.

Title: Improvements in transistor switching circuits
IPC: H03K19/086
Filed: 1957-11-15
Abstract: 872,251. Transistor logical switching circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 15, 1957 [Nov. 15, 1956], No. 35728/57. Class 40(6) In a circuit comprising a series of transistor 1 A , 1 B , . . . 1 N  in a first current path and a secondtransistor 15 of the same conductivity type in a second path with a common electrode of all the transistors connected to a current source 8, current flows in the first path until all the transistors 1 A  . . . IN are cut off, whereupon current flows in the second path. The circuit of Fig. 4 provides an OR function, a negative potential applied to the base lead of any of the transistors 1 A  . . . IN causing it to conduct and pass current through the common collector load. Due to the fall in potential across resistor 7, transistor 15 cuts off and remains so until all the transistors 1 A  . . . 1 N  are cut off when the emitter potential rises and transistor 15 conducts. In a modification, Fig. 5 (not shown), the input to transistor 1 A  is derived from an OR circuit of NPN transistors, similar to Fig. 4 but with transistor 15 replaced by a diode through which current flows when all the NPN transistors are cut off. An EXCLUSIVE OR function is provided by a pair of circuits, Fig. 6, inputs p, q and p, q being supplied to them respectively.

IPC: H03M1/00
Filed: 1959-10-22
Abstract: 888,619. Electric selective signalling systems. NORTH AMERICAN AVIATION Inc. Oct. 22, 1959, No. 35866/59. Class 40 (1). A decoder for converting digital error signals in a servo system into analogue form, includes at least two electrical networks having impedances in two different ranges of magnitude and a device for controlling the connection of one network to the other to increase the capacity of the apparatus when a large error occurs or is anticipated. As described, a motor 10, having a fixed potential applied to its armature winding 11, is controlled from a D.C. amplifier 15 connected to one end of its field winding. The shaft 10<SP>1</SP> of the motor drives a motionto-pulse converter (or tachometer) 16 which supplies subtracting or adding pulses via synchronizers 18 and 17, respectively, to a binary electronic counter 21. A further input of adding pulses, via a synchronizer 19, is fed to the counter from a pulse generator 20 in accordance with a programme (e.g. for movement in a machine tool). Resistors 28 ... 31, weighted in correspondence with the values of the counting stages 22...25 which bring them into operation, vary the potential at 34 which controls the amplifier 15. When sudden changes occur or are anticipated, a transistor amplifier 40 is brought into operation by the programme device 42 and energizes a solenoid 30 closing a switch 37. This brings additional stages 26, 27 into the counter circuit with correspondingly weighted resistors 32, 33 whose tolerances need not be so critical as they would have to be if these stages were permanently in the circuit. A balancing resistor 38 avoids unwanted changes in potential at 34 when the switch 37 closes. In a second embodiment (Fig. 4, not shown), this compensation is achieved by switching in another bias 14 for the field winding. A known type of programme device (Fig. 2, not shown), is described. U.S.A. Specifications 2,537,427 and 2,552,968 are referred to.

The frames 48, 50 not only telescope within a main frame 40 but frame 48 also telescopes with frame 50. The telescoping results (e.g. for frame 48), from rotation of a toothed roller 150 which co-operates with openings 154 formed in a bottom plate 132 of the frame. The roller 150 is reversably driven by an hydraulic motor 156. The conveyer belt 52 is driven, via a roller 210, by a reversible motor 212 and has a tensioning mechanism 220. The way in which the change in length of the upper run of the belt is accommodated is indicated in Fig. 7. The conveyer is supported on castor wheels 43 and on wheels 42, the latter being independently and hydraulically driven for speed control and steering. In loading a trailer 14 with mail bags one operator may stack the bags discharged from the frame 48 and another operator may load bags on to the frame 50. The frames may be moved independently of each other or in equal but reversed directions in synchronism. Control panels 62, 63, 65 are provided for these and the other operations.

Abstract: 1,182,130. Injection moulding. ROLINX Ltd. 25 July, 1968 [4 Aug., 1967], No. 35973/67. Heading B5A. An injection mould cavity 3, which is expanded during the injection and contracted during the cooling of the moulded article therein, is formed by relatively movable mould members 1 and 4 and a ring 10 embracing the member 4 and axially slidable thereon. The parts 4 and 10 are forced against the member 1, and when plastics material is injected through inlet 2 the member 4 is forced away slightly from the member 1 and slides on the ring. Pressure is maintained on the mould parts so that shrinkage of the moulded article permits the member 4 to move towards member 1. Hydraulic rams 9, 12 may urge the parts together or toggle mechanisms may be used. In the embodiment of Fig. 2 (not shown), the ring is in slidable contact with the fixed upper mould member and is hydraulically forced into engagement with the movable lower mould member.

Title: Improvements in desiccators for drying air or other gases
Inventor: ROBINSON VICTOR SNOW
IPC: B01D53/04
Filed: 1961-10-06
Abstract: A desiccator for drying compressed air or other gases comprises a container for the desiccant through which the gas to be dried is passed and a vacuum pump connectible thereto, the exhaust of which is in communication with the atmosphere.  By creating a vacuum in the desiccator the temperature at which water present in the desiccator vaporizes is reduced, thereby facilitating reactivation.  Ambient temperature may be sufficient for reactivation if the degree of vacuum is sufficiently low, e.g. 0.23 p.s.i. abs., but the exhaust from the pump may be employed to supply heat.  In the preferred embodiment (Fig. 1 not shown) cylinders 1 and 2 contain heating coils 31 and 32 and have connections 51 and 52 for incoming gas, and 61 and 62 for outgoing dry gas, vacuum connections 71, 72, and exhaust gas connections 81, 82 to said coils.  When cylinder 1 is in drying phase, wet gas is passed thereto whilst the other cylinder 2 is connected to vacuum pump 10, the exhaust of which is passed through cooling coil 32 and thence to atmosphere.  Change-over is effected when a humidity detector 13 indicates that the water level in the product gases has reached an unacceptable level.  The four valves 63, 73, 53 and 83 may if desired be ganged to a common operating spindle for simultaneous operation.  If desired the cylinders may be surrounded with evacuable jackets.

Abstract: 1486369 Bearings KUGELFISCHER GEORG SCHAFER & CO 3 Sept 1975 [12 Oct 1974] 36361/75 Heading F2A A bearing assembly comprises an axially loadable rolling bearing 2 and a hydrostatic axial bearing arranged in tandem such that the same proportions of the load F on a shaft 1 mounted in the bearings are applied to both bearings independently of the magnitude of the load. The outer race 21 of the rolling bearing transmits load to a housing 4 through an axially slidable piston-like bush 3. The hydrostatic bearing is formed between a ring 5 attached to the shaft and a pocket 8 in one face of an axially movable piston 6. In operation, oil is supplied under pressure to a chamber 9 formed between the rear face 6<SP>1</SP> of the piston 6 and the housing 4. Excess oil passes through a throttled passage 7, 7<SP>1</SP> to the pocket 8. The hydrostatic bearing is thereby brought into operation and relieves the loading on the rolling bearing. With further increase of oil pressure, the face 3<SP>1</SP> of the bush 3 is moved away from housing 4. Excess oil then runs through the gap to a groove 15 and from there back to an oil supply tank. A spring 12 is provided to keep the piston 6 out of contact with the ring 5 before the hydrostatic bearing is in operation. The whole assembly can be mounted in the bore of an outer housing structure 11 and secured by means of an end cap 13.

Abstract: 412,266. Timing ignition. DELCOREMY CORPORATION, 329, East 1st Street, Dayton, Ohio, U.S.A.-(Assignees of Arthur, J. L. ; R.R. 7, Edgewood, Anderson, Indiana, U.S.A.) Dec. 23, 1932, No. 36487. Convention date, Dec. 30, 1931. ' [Class 7 (iv).] Ignition is retarded while the engine is idling by a device responsive to induction pipe suction, the device serving to advance the ignition when the engine is under part-load. To the housing of an interrupter-distributer unit is clamped an arm connected by a rod 67 to a diaphragm 97, the compartments 90, 91 adjoining which are connected by pipes 107, 117 to openings 111, 119 on the induction pipe, the opening 111 being on the engine side of the throttle 112 when closed, and the opening 119 on the carburetter side. Movement of the diaphragm in either direction is opposed either by a single helical spring, or by two springs, one within the other. Under idling conditions with the valve 112 closed, the vacuum exerted in compartment 91 by way of opening 111 retards the ignition. As the throttle valve 112 is opened suction through the opening 119 increases and relative advance occurs. At higher speeds when the suction in the induction pipe is small, the centrifugal governor enclosed in the interrupter housing effects the required advance. Stops 81, 82 limit the movement of the diaphragm 97 ; manual adjustment may be effected by a Bowden wire 78 attached to the support 70.

In apparatus for carrying out the method, molten metal 1 is poured through a refractory nozzle 3 of a tundish 2 and is atomized and cooled by jets of nitrogen, argon, or a mixture of carbon monoxide, carbon dioxide, nitrogen and hydrogen at ambient temperature discharged from an atomizing device 4. The spray 6 of hot particles is deposited on the collecting surface or die 7 to form the preform 8 which may be removed by an ejector 9. The preform may be transferred directly or at some later stage to the dies 10, 11 of a drop-forging hammer to produce a forging with or without the addition of heat, surplus flash being trimmed off to produce the precision article such as a gear, lever, cutting tool, impeller blade, rocker arm, &c. The precision article may be formed by pressing or extrusion. More than one spray may be used acting simultaneously or consecutively and relative movement may be effected between the spray and collecting surface. The metal or alloy may be carbon or alloy steels, aluminium, aluminium alloys, brass, phosphor bronze, nickel or cobalt based alloy. The article may comprise a mixture of materials which are mixed in flight or sprayed so that the article is formed of layers of different material. Fibres, filaments or whiskers may be incorporated in the sprayed material.
