Abstract: 1389506 Measuring electric power G WAURICK 5 Sept 1973 [5 Sept 1972] 41835/73 Heading G1U In the measurement of A.C. power, instead of the power factor cos # an 'energy factor' is used, this being derived from a signal resulting from multiplication of the instantaneous values of current and voltage and being equal to A-B divided by A+B, where A and B are respectively the integrated positive and negative values of the multiplied signal. The figure shows apparatus for deriving the 'energy factor' in a three-phase supply A, B, C. Multipliers Ia - Ic feed a first integrator 4 direct, whose output thus represents A-B and a second integrator 5 via invertors 6a - 6c and diodes 7a - 8c, the integrator 5 output thus representing A+B. Divider 9 provides the required quotient. The method is said to be particularly applicable to low power factor situations, where large currents would be needed to drive a normal two-coil wattmeter.

Title: Fuel injection systems
IPC: F02M69/42
Filed: 1974-09-27
Abstract: 1485838 Fuel injection systems ROBERT BOSCH GmbH 27 Sept 1974 [28 Sept 1973] 42065/74 Heading F1B A fuel injection system for mixture compressing, spark-ignited I.C. engines with continuous injection into the intake pipe, comprises an air-flow measuring element and a throttle valve in series in the intake pipe, the measuring element being, in use, arranged to be displaced against a restoring force through a distance proportional to the quantity of air flowing through the intake pipe and to adjust a movable part of a fuel metering valve, the fuel pressure within the system being variable so that it can be reduced to produce enrichment of the fuel/ air mixture during the warming-up phase of the engine. Air drawn into intake pipe 1 angularly displaces a flap 2, hinged along one edge on axle 3. A spring 4 resists the movement, which is transmitted by coupling 6 to rotary valve-member 7. Pump 10 supplies fuel from tank 11 to passage 13, annular groove 14 in member 7, passage 15 and chamber 16 where it acts on one side of diaphragm 17. Fuel is able to return to tank 11, via pipe 23, when the pressure in chamber 16 lifts diaphragm 17 off valve seat 22. Fuel from annular groove 14 also enters longitudinal groove 18 which overlaps a groove 19 in the surrounding bore to a greater or lesser extent according to the angular position of flap 2. From groove 19 fuel passes through passage 20 to chamber 21, where it acts on the other face of diaphragm 17, and then to chamber 26 where it unseats diaphragm 17 from valve seat 29 and passes through passage 30 to enter the intake pipe at a point immediately downstream of the throttle valve. Diaphragm 17 is held against seat 29 by ball 33 loaded by spring 31. A bi-metallic strip 35, when cold, acts against spring 31 to reduce its effective force and hence the pressure which must be developed in chamber 26 to unseat the diaphragm. An electrically powered heater 36 is provided which when energized causes strip 35 to bend towards diaphragm 17 so that spring 31 acts with a maximum force on ball 33. In the chamber 21 a spring 40 which biases valve 24 in the closing direction abuts a piston 43 at one end and at the other end bears on a plate 41 which is rigidly attached to ball 42. Fuel which has passed through the metering valve and which leaks past piston 43 passes along a pipe 49 to the inlet manifold to a point downstream of the throttle valve.

Abstract: 921,641. Laminating. E. S. & A. ROBINSON Ltd. Dec. 12. 1960 [Dec. 11, 1959], No. 42258/59. Class 140. Cardboard is laminated to paper or other flexible material in web form by feeding two or more webs of board in untensioned condition side by side and spaced apart, and tensioning them before they proceed to the laminating unit. Preferably the board webs are formed by slitting a single web and the paper &c. web is correspondingly slit, but into wider webs the edges of which are turned over and secured to the reverse sides of the board webs. The products may be used for making boxes and lids. As shown a web of cardboard 1 is drawn from a reel 2, under tension, by rolls 3, is thereafter freed from tension and accurately presented by side guides 4 to rotating or non-rotating rolls 5, and is slit while tensioned into two webs at 6. The webs are detensioned in passing between rolls 7 and allowed to run free and to separate while travelling to guiding means comprising a plate 9, side guides 8 and a riding roll 10. The laterally separated webs then pass around a rubber covered or other tensioning roller 11 and upwards to rollers 12 where they are laminated to paper webs 13 drawn as a single web, wider than the web 1, from a reel 14, slit at 15 and coated with adhesive at 16. The combined webs pass to a unit 17 which turns over the edges of the paper webs on to the reverse side of the board.

Abstract: 936,393. Photomechanical relief printing- plates. K.-H. KRETZER. Dec. 16, 1959, No. 42794/59. Class 98 (2). A process of producing a relief printing-plate for colour printing from a screen positive produced from a photomechanically corrected halftone negative comprises exposing to light through such screen positive a metallic base carrying a layer of light sensitive material which is rendered removable by photo-chemical action, removing the exposed portions of the layer, and subjecting the base with the remaining portions of the layer thereon to a partial single stage etching process which is ineffective on the non- exposed portions. In the example the plate is a zinc plate; the light-sensitive layer is composed of a solution of 4-[naphthoquinone-(1,2)- diazide - (2) - sulphonyloxy - (5)] - 2 - hydroxy - acetophenone, m-cresol-formaldehyde resin and sesame oil in ethylene glycol monomethyl ether, optionally containing methyl violet BB to increase contrast; and the solvent used to remove the exposed portions is a 2% aqueous solution of trisodium phosphate containing 10 to 15 volume per cent of ethylene glycol monomethyl ether. An advantage claimed for the process is that colour and tone value corrections can be effected on the screened photographic positive rather than on the printing plate.
