Title: Arrangement for controlling the air-fuel ratio of the combustible mixture supplied to an internal combustion engine
IPC: F02D41/14
Filed: 1975-11-14
Abstract: 1506248 Regulating IC engines; spray carburetters NISSAN MOTOR CO Ltd 14 Nov 1975 [14 Nov 1974 7 March 1975] 47023/75 Headings FIB and F1H [Also in Divisions G3] An arrangement for controlling the air/fuel ratio of the mixture supplied to an engine to give a cleaner exhaust operates by making the mixture alternately rich and weak and arranging that each cylinder is supplied with both concentrations to obviate carbon deposits and other damage. As shown in Figs. 3 and 4 an exhaust gas sensor 18  provides a signal which is compared with a reference level in generator 100 to produce a control signal S4 which is used to sample a repeating waveform S5 in comparator 200a. The waveform S5 is derived from a regular pulse train S1 proportional to engine speed by counter 200c and D/A converter 200b, Fig. 4. The pulse signal S2 from comparator 200a operates a pulse generator 200d to produce a further pulse train having a frequency equal to that of pulse train S1 where the duration of the pulses in the presence of pulse S2 is short and in the absence of pulse S2 is long. The pulses S3 are used to operate the injectors 111-116 of the engine 10 so that for a short pulse the mixture is weak and for a long pulse the mixture is rich. The number of injections of each type are controlled by the mark/space ratio of signal S2 which is dependent on the engine operating variable sensed, e.g. exhaust gas composition. In the carburetter arrangement shown in Fig. 6 and modified in Fig. 9 (not shown) the fuel valve 16 is shifted to open either high flow passage 48 or low flow passage 50 by the presence or absence of pulses 52 to give a rich or weak mixture supply to the engine. The valve 25 is controlled by controller 20 to cause a quantity of fuel to be ejected from orifice 34 in accordance with the sensed operating parameter. In a modification, Fig. 9 (not shown) a differential generator and pulse generator arrangement, similar to that shown in Fig. 4, is used and controls both the fuel valve and the air valves.

Title: Process for preparing Non-Woven Fibrous Products from Gel Fibers
Inventor: SPENCE THOMAS CECIL
IPC: D04H3/14
Filed: 1967-02-24
Abstract: 1,188,325. Papermaking, non woven fabric. DOW CHEMICAL CO. 24 Feb., 1967 [26 July, 1966], No. 47025/69. Divided out of 1,188,322. Headings D1R, D2A and D2B. A dry non-woven fibrous sheet is made from a web of selfbonding gel fibres (defined as in the parent specification) of thermoplastic, fibre-forming polymers of acrylonitrile, by subjecting it to drying conditions between two spaced barriers that limit the physical movement of the web in its thickness direction while providing substantially no restraint to movement in other directions. The barriers may be solid screens or platens or heat barriers, but are preferably hot bodies such as platens that will serve both as solid barriers and as heat barriers. The barriers may be applied throughout the drying period, or only in its earlier part (when most of the movement would otherwise take place). The fibres may be fibrillated by beating and may first be crushed to induce longitudinal splitting and so to facilitate this fibrillation. The crushing is preferably carried out before cutting to staple length, and may be applied by crush rollers, serrated-belt crimpers, gear crimpers or a stuffing-box crimper. The web may be formed by a scattering mechanism, distribution by a stream of air or water, or deposition by filtering from a liquid. Staple fibres, are preferably formed into a web by papermaking technique and continuous filaments also from suspension in water. The rate of drainage of aqueous slurries may be controlled by the process of Specification 1,188,323. The gel fibres may be toughened before sheetformation by subjecting them while free of restraint to a hot aqueous medium, but they must then be cooled before subjecting them to stress. The web may be first pressed as in the parent specification and then dried by the process of the present invention. Various textures can be produced by varying the conditions; mild pressing will give a fluffy product; pressing at higher temperature and pressure will give a leathery product of higher tensile strength; drying between heated surfaces spaced apart by two to five times the thickness of the web before drying will give a product with a straight core and crimped surfaces. The dried web may subsequently be annealed at a temperature at least 30C above the glass-transition temperature of the fibres. The specification also describes by way of comparison similar sheets dried with no restraint at all.

Abstract: 1,197,349. Delivering sheets. JAGENBERG WERKE A.G. 9 Oct., 1968 [4 Nov., 1967], No. 47788/68. Heading B8R. [Also in Divisions G4-G6] A jet of air is directed towards the path of travelling overlapping sheets to effect a count. The leading edge of a sheet 1 is lifted by the jet of air from a nozzle 9 so as to shield a flap 10 pivoted at 13. When the leading edge passes, the jet acts on the flap which swings clockwise, so that a mirror 16 reflects light on to a photo-cell 11 to step a counter 12. Stops 14, 15 limit movement of the flap. Alternatively (Fig. 3, not shown), the stops may carry electric contacts. In a further modification the passage of the leading edge affects the pressure of the air supply, the pressure pulse stepping the counter.

Abstract: 1,209,180. Control of A.C. motors. ROBERT BOSCH G.m.b.H. 25 Oct., 1967 [25 Oct., 1966], No. 48454/67. Heading H2J. A vehicle is propelled by at least one threephase induction motor 13 which is energized from a D.C. source such as a fuel cell 10 via an inverter 11 whose output frequency is controlled so as to regulate the slip speed of the motor 13 to a desired value. The inverter comprises thyristors and as shown these are triggered by a magnetic impulse generator 21 driven by the armature of a D.C. motor 19 whose field 18 is rotated directly by the induction motor 13. Thus the speed of the D.C. motor, adjustable by rheostat 24, represents desired slip of the induction motor, and if the actual slip varies the resulting change in the rotation of the field 18 causes adjustment of the frequency of the invertor 11 and the slip is restored to the prescribed value. In Fig. 3 (not shown) the D.C. motor is dispensed with, the actual slip being detected by a search coil and compared with an electrical reference value, the difference effecting control of the inverter. In both cases there may be an overriding current limit control, the value of the limit being related to the speed of the motor, and regenerative braking may be used during which magnetizing current is supplied by capacitors 15. There is one induction motor and a variable gear-box and/or clutch 16 for each driving wheel.

Title: Television receiver line output stages

Filed: 1975-11-26
Abstract: 1531009 CRT line output circuits COMMUNICATIONS PATENTS Ltd 17 Nov 1976 [26 Nov 1975] 48537/75 Heading H4T A TV receiver line output stage includes a line transformer 1, means 6 for drawing an EHT supply from the transformer, and means for controlling the flyback time to regulate the EHT. The regulation circuit includes a capacitor 9 which, during the rising positive part of the flyback, is coupled across a winding 10 of the transformer by the forwardly-biased diode 11. This slows down the flyback whereby the EHT is reduced. If, during a scan period, the capacitor 9 discharges through resistor 12 and transistor pair 13, then on subsequent cycles the flyback will be slower and the EHT reduced. The transistor pair is normally held conducting by the base current through resistors 14, 15. If the beam current increases, the EHT is reduced, causing a negative charge to build up on capacitor 8. The resulting current through resistor 7 reduces the base current in the transistor pair, thereby increasing the EHT.
