Title: Lubricating oil treatment system
Inventor: GEYER JEROME
IPC: B01D35/00
Filed: 1969-11-28
Abstract: 1,263,368. Treatment of used mineral lubricating oils. ESSO RESEARCH & ENG. CO. 28 Nov., 1969 [16 Dec., 1968], No. 58245/69. Heading C5E. In an oil filter through which circulating mineral lubricating oil is passed in connection with the operation of an internal combustion engine, the filter contains elemental red phosphorus in solid particulate form, the size of the particles being sufficiently large to be retained by said oil filter.

Title: Display System
IPC: G09G1/18
Filed: 1967-12-28
Abstract: 1,174,000. Cathode-ray tube displays. BUNKER-BAMO CORP. 28 Dec., 1967 [20 Jan., 1967], No. 58900/67. Heading H4T. In a cathode-ray tube display system in which symbols &c. are produced in a " dot " matrix format by intensity modulation of the beam at selected positions as it is deflected in a plurality of e.g. vertical, " writing " strokes during each (horizontal) sweep the brightness of the display is enhanced by producing a controlled increase in the effective width of the writing strokes at the selected positions or by prolonging the duration of each intensity modulation pulse or by a combination of both. Thus, as shown in Fig. 1, the beams of a plurality of cathode-ray tubes 10A ... 10N, on each of which different symbols are to be displayed in accordance with the cyclic outputs of a multiplexor 52 supplied with symbol defining video (bright-up) pulses, are deflected in a succession of horizontal lines at different vertical position by sweep generator 28 and vertical step generator 20 and in a plurality of vertical " writing " strokes by sweep generator 22. The symbols are then produced by supplying the outputs from the various stages of the multiplexor to the beam intensity control electrodes of the tubes via trigger circuits 48A . . . 48N. To enhance the brightness of the resulting displayed symbols the duration of the bright-up pulses produced by the trigger circuits is made equal to the duration of N-1 pulses from the multiplexor and the effective width of the elongated brightened vertical portions of each vertical " writing " stroke (Fig. 4) is then increased by superimposing a triangular waveform from generator 32 on the normal horizontal sweep so that the symbol has the form shown in Fig. 3 in which each " dot " comprises a square of uniform brightness. When the squares are employed to indicate plot points on more than one graph the points appertaining to e.g. a second graph may be given a different form by replacing the triangular waveform generator by a generator 40 producing a step waveform with steep sides and two horizontal steps so that the symbol has the form shown in Fig. 6.

Abstract: 1286968 Moulding spools SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 24 Dec 1969 [4 July 1969] 62784/69 Heading B5A [Also in Divisions B8 F2 and H1] A method of producing an insulation sleeve for the core of a relay spool includes rolling a length of insulating tape 4 in a hollow cylinder 5, transferring the roll 10 to the cylindrical cavity 12 of a mould 14, heating the mould and allowing it to cool whereupon the tape 4 now retains its rolled shape. As shown the tape is cut from a roll 2 by cutters 3, drawn into the cylinder 5 and rolled by tool 9 having a tape gripping notch 8. A mandrel 11 is used to transfer the tape 4 from the cylindrical cavity 12 to mould 14. Flared ends may be produced in one or both ends of the spool while the mould 14 is heated by means of a punch 18. When assembled as part of a relay, the spool may be slid over the core and if it has plain ends the ends of the spool are received in annular recesses in flanges mounted on the ends of the core and if it has flared ends these ends abut the inner surfaces of the flanges. In either construction the windings of the relay are separated from the core.

Title: Pseudo-random noise generator
IPC: H04J3/14
Filed: 1978-10-06
Abstract: Arrangement for generating a sequence of pseudo-random numbers constituting a band limited noise signal for testing a voice channel of a p.c.m. telephone system. A pseudo-random pulse sequence generator 1 comprising a feedback shift register feeds a digital filter 6 comprising a series in - parallel out shift register 9. At each clock the outputs of register 9 are each multiplied by an individual binary number and the results are summed at 11. Each binary number at 8 is then multiplied at 12 by a common number 13 to adjust the amplitude and by varying numbers at 14 according to a companding law. The generator 1 may be preset at intervals by inputs 7 so as to reduce the sequence length and thus change the peak to RMS ratio of the signal. <IMAGE>

Abstract: A low compression ratio internal combustion engine includes a piston and cylinder arrangement 11, 12, an inlet valve 15, an exhaust valve 16, and a regenerative heat exchanger 18 which is located within the working volume of the cylinder, the heat exchanger 18 having a hot face 22 and a cold face 19 between which gases are caused to flow. A piston 27 is raised during the power stroke to block a passage 14a so that the inlet charge is caused to flow through the heat exchanger 18 from the cold face 19 to the hot face 22 so as to be heated immediately prior to the combustion stage of the engine operating cycle, the burning and expanding fuel/air mixture acts directly on the piston 11 without passing through the heat exchanger 18, and the products of combustion are subsequently caused to flow through the heat exchanger 18 from the hot face 22 to the cold face 19 to heat the heat exchanger 18 before leaving the working volume by way of the exhaust valve 16. The heat exchanger may be attached to the moving valve sleeve of a two-stroke engine or it may be included in a four- stroke engine having a pair of cross- connected cylinders. Alternatively the heat exchanger may be rotatably mounted in a four-stroke, single cylinder engine. <IMAGE>

Title: Method of forming sealing gaskets in container closures
IPC: B29C70/80
Filed: 1980-06-10
Abstract: A method of forming a sealing gasket in a container closure of a high-melting point olefin polymer, which is substantially transparent to microwave radiation comprises depositing and forming in the closure a plastisol of a vinyl chloride resin, heating the thus formed plastisol by microwave energy and heating the closure so that at the time of microwave heating it reaches a temperature of 5 DEG to 35 DEG C below its melting temperature. In this way overheating of the interior of the plastisol is avoided. Heating of the closure is effected by conventional means such as a preheating hot air oven.
