Title: A Control System for the Current Supplied to a Direct Current Load.
Inventor: PUTZ ULRICH
IPC: H02P7/29
Filed: 1966-11-02
Abstract: 1,166,277. Control of D.C. motors. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. 2 Nov., 1966, No. 49222/66. Heading H2J. A switching device 10 through which a D.C. load such as a motor 1, 2 is supplied from a D.C. source U = is controlled by a device 5 which switches it on and off according to the difference between the actual current (measured at 4) and the sum of two "desired value" inputs to 5, namely a basic one derived from a potentiometer 6 and a variable one which is dependent upon the relative on/off time of the switching device. This variable reference is derived from the average voltage across the switching device. The object is to permit a higher load current when the on/off ratio is low than would be safe when the ratio is high. The variable reference is applied via a diode 17 and transistor 19 which is arranged so that the variable reference is only effective when it is less than the basic reference from potentiometer 6. The switching device comprises a thyristor 11 and a commutating thyristor 12, capacitor 14 and choke 15.

Abstract: 1,186,702. Gauging screw threads. JOHNSON GAGE CO. Sept. 26, 1967, No. 50672/68. Divided out of 1,186,701. Heading G1M. A thread gauging device has a fixed arm 54, a movable arm 55 pivotably connected to the fixed arm and four gauges mounted on the arms, each gauge having at least one gauging element mounted on the fixed arm and at least one gauging element mounted on the movable arm. The gauge 2 has gauging elements 60, 63 provided with gauging surfaces 62, 65 for engaging a test part at diametrically opposite points. The gauge 1 has three gauging elements 68, 70, 71 to engage a test part at three spaced points around its circumference. A pair of gauges similar to the gauges 1, 2 but having different gauging surfaces are mounted on the opposite sides of the arms.

Abstract: 1,025,064. Suction cleaners. K. E. MERKLE. Jan. 24, 1963, No. 51096/65. Divided out of 1,025,063. Heading A4F. [Also in Divisions B1 and B2] A vacuum cleaner by means of which air is purified and sterilized is provided with a cathode filter element 34 connected to a direct current source 35 so that foreign bodies present in the air passing through the vacuum cleaner are attracted by the cathode and negative ions are generated and radiated into the surrounding atmosphere. The cleaner incorporates a fan 30, a porous dust bag 31 and an anode filter element 33. The element 33 and 34 may be in the form of removable metal filing filters. The source 35 is constituted by a transformer and rectifier assembly and may be permanently or detachably mounted on the outside of the casing 27. Sterilization of the air may be further increased by the addition of ozone which may be produced either separately and introduced into the air passing through the cleaner or by setting up an electrostatic field between the filter elements 33 and 34, the passage of the air through the field resulting in the production of ozone. In the latter case; the filter element 33 may be adjustably movable relative to the filter element 34. Alternatively, the elements 33, 34 may be at a fixed distance apart and a third movable cathode or anode elements is located between them. Further sterilization may be obtained by locating an ultra-violet light generator and/ or radioactive elements outside the casing 27, or inside the casing between, or outside, the fitter elements 33 and 34. The ultraviolet light generator can be employed simultaneously or independently.

Title: Method and apparatus for continuous grease manufacture
IPC: B01F5/10
Filed: 1964-12-16
Abstract: <PICT:1046090/C4-C5/1> In a continuous process for manufacturing lubricating grease including soap grease, saponifiable material and metal base are reacted in a reaction zone; the reaction product is dehydrated in a dehydration zone and the mixture is recycled from the bottom to the top of the dehydration zone through a shear valve so that the soap is simultaneously conditioned.  Predetermined amounts of lubricating oil are added at each stage, but a lubricating oil hydrolysable under saponification conditions would not be added at this stage.  The metal base may be the oxide, hydroxide or carbonate of an alkali metal, alkaline earth metal, magnesium, zinc, cobalt, manganese, aluminium or lead; the saponifiable material may be a fatty acid having 12 to 32 carbon atoms or an ester thereof, or a mixture thereof with a fatty acid having 1 to 6 carbon atoms; the lubricating oil may be a naphthenic and/or paraffinic mineral oil, a synthetic oil obtained by cracking a polymerization or a high molecular weight ether or ester, diesters such as di-2-ethylhexyl sebacate, or a mixture of any of the foregoing.  As shown, saponifiable material, optionally containing lubricating oil, is introduced from tank 15, metal base in aqueous solution or oil slurry from tank 20, and lubricating oil mainly from tank 40 and, optionally, when more than one oil is to be used, tank 60. As shown, the lubricating oil may be introduced into the system at a number of points.  The mixture is recycled through tubular reaction zone 1 by means of line 7 and pump 10 at a velocity giving highly turbulent flow, reaction taking place at 10-300 p.s.i.g. at 180 DEG  F. or above.  The reaction product is passed via line 26 and pump 27 to dehydration zone 30, maintained therein at above 225 DEG  F. and recycled from bottom to top of the zone by pump 34 through shear valve 37 having a pressure drop of 10 to 200 p.s.i.g. across it.  The volume of recycled grease mixture during the average residence time in the dehydration zone is at least five times the total average volume of mixture in the zone.  Lubricating oil added at this stage comprises at least 25% of the mixture. The dehydrated grease mixture is withdrawn from line 33 via line 75, and oil added at this stage, comprising up to 90% of the total oil content, is advantageously used to cool the mixture. Also added at this stage are additives, from tank 90 and, in the case of cup greases, water of stabilization.  The mixture is circulated through shear valve 81 and, if necessary, cooler 85.  The product grease is taken off via line 87 and a further valve 88 after final required addition of oil have been made via line 71 and pump 72.

Abstract: 1,243,588. F.E.T. Memory circuits. NORTH AMERICAN ROCKWELL CORP. 20 Oct., 1969 [7 Jan., 1969], No. 51400/69. Heading H3T. A capacitor 6<SP>1</SP> connected between the output (drain) and control (gate) terminals of a F.E.T. 13<SP>1</SP> is arranged to store binary information (supplied via F.E.T. 9) and when this information makes the left-hand plate of C6<SP>1</SP> negative, the F.E.T. 13<SP>1</SP> is held conductive so that a negative read pulse from 17<SP>1</SP> appears at the drain and is fed back through C6<SP>1</SP> to increase the conduction of F.E.T. 13<SP>1</SP> and to reduce thereby the voltage drop across it. A F.E.T. 3<SP>1</SP> in an address matrix 201 connects an information conductor 16<SP>1</SP> to the memory circuit incorporating F.E.T. 13<SP>1</SP>. A write F.E.T. 9<SP>1</SP> is then made conductive to charge the capacitor 6<SP>1</SP> to the potential of the conductor 16<SP>1</SP>. A F.E.T. 30 may also be provided to hold the right-hand plate of capacitor 6<SP>1</SP> at the earth potential present at the read pulse source 17<SP>1</SP>. If F.E.T. 30 is not used (Fig. 1, not shown), then when a zero potential is applied through F.E.T. 9<SP>1</SP> to discharge 6<SP>1</SP>, if it is not already discharged, the F.E.T. 13<SP>1</SP> will cease conduction at the point when the voltage still remaining on C6<SP>1</SP> is equal to the threshold voltage of F.E.T. 13<SP>1</SP>. This residual stored voltage is undesirable but may be partly dissipated by the stray capacitance (11) to the substrate. Prior to a read pulse from 17<SP>1</SP>, a read/reset pulse is applied to a F.E.T. 12<SP>1</SP> so that stray capacitance 10<SP>1</SP> and a discrete capacitor 7<SP>1</SP> are discharged to the earth level at 17<SP>1</SP> through F.E.T. 13<SP>1</SP> provided that C6<SP>1</SP> is storing an appropriate voltage to make F.E.T. 13<SP>1</SP> conduct. To read, a negative pulse from 17<SP>1</SP> passes through F.E.T. 13<SP>1</SP> (whose voltage drop is minimized as already explained), and through F.E.T. 12<SP>1</SP> to the capacitor 7<SP>1</SP>, from which it is extracted by means not shown to provide the circuit output. A reset F.E.T. (31) is provided to discharge the line (16<SP>1</SP>).
