Abstract: 1319982 Spray carburettors; regulating ignition timing REGIE NATIONALE DES USINES RENAULT AND AUTOMOBILES PEUGEOT 18 Sept 1970 [23 Sept 1969] 44699/70 Heading F1B A device for reducing atmospheric pollution during overrun of a vehicle engine comprises an A.C. generator 4, Fig. 1, driven from the vehicle transmission and connected via a transistor 8 to a diode pump 9-13 which is connected via an emitter follower 15 to an electronic switch comprising transistors 18, 19, 20 with positive feedback via a resistor 31 and an emitter follower output to the winding 29 of an electromagnetic valve 43, Fig. 3. At speeds above idling speed, the frequency of the output of generator 4 is high enough to reduce the output voltage of the diode pump to a value at which it triggers the electronic switch to its non-conductive state, thereby de-energizing the winding 29 to move the valve 43 from a position in which a diaphragm chamber 41 is vented to atmosphere via an orifice 45 to a position in which the diaphragm chamber is subjected, via a pipe 44, to the vacuum in the induction manifold of the engine 37. The diaphragm then acts on the throttle valve 40 to increase its minimum opening beyond the idling opening to ensure good combustion during overrun. When the manual control 49 of a choke or enrichment device is operated, a contact 48 energizes the winding 47 of an electromagnetic valve 46 to disconnect the vacuum chamber 50 of the distributor 39 from the vacuum pipe 52 and connect it instead to the induction manifold via the pipe 44, to provide a vacuum advance of the ignition even when the accelerator pedal is released. Alternatively, the vacuum chamber 50 may be vented to atmosphere by an electromagnetic valve energized in parallel with an electromagnetic valve 34 controlling the automatic transmission in accordance with the output of the generator 4.

Abstract: 1,113,059. Ventilating garments. SHIRTMAKER Ltd. 3 Nov., 1965 [3 Nov., 1964; 11 Nov., 1964], Nos. 44785/64 and 45903/64. Heading A3V. [Also in Divisions B5 and D1 A textile fabric is formed with at least one ventilation opening by forming at least one region in the fabric where the fabric fibres are bonded together or otherwise consolidated as a result of consolidation of a thermoplastic constituent of the fibres of the fabric and forming an opening in the or each region. The invention is applicable to forming underarm ventilation openings in sleeved garments, e.g. shirts, blouses or raincoats. In one embodiment, Fig. 1 (not shown), a knitted or woven fabric (1) of a yarn consisting of or comprising synthetic thermoplastic material, e.g. polyamide, polyester or acrylic material, is formed with consolidated regions (2) using electric high frequency heating or ultrasonic energy. Openings (4), preferably circular, are punched in the region (2) and are surrounded by reinforcing rims (3) which prevent fraying in the region of the openings. The punches may be situated in the electrodes or ultrasonic guide means. In a second embodiment, Fig. 2, a portion 6, either of fabric woven or knitted from a yarn consisting of or containing synthetic thermoplastic material, e.g. polyamide, polyester or acrylic material, or of a sheet of synthetic thermoplastic material, is welded by high frequency heating to the fabric 5 at regions 7 and a line 10 by rims 14, 13, respectively, Fig. 3, of an electrode which may co-operate with a similarly shaped counter electrode or a flat electrode. Simultaneously with forming the seam line 10 surplus parts of the portion 6 are trimmed off. Punches 17 in bores 16 are driven downwardly by a cam (not shown) to form openings 9 each surrounded by a welded rim 8. The operation of the electrode may be controlled by a mechanical linkage or by electromechanical control means operated by a foot switch actuated by the operator. Alternatively ultrasonic energy may be used for the welding. In a modification, the reinforcing material is applied in the form of a granular or powdered synthetic resin. In a further embodiment, Fig. 4, a fabric 20 is positioned between a backing member 21 and a mould member 22. Synthetic thermoplastic material is injected into a cavity 23 in the member 22 through a duct 24 to provide a reinforced region in the fabric.

Title: Optical velocity measuring apparatus
IPC: E04G21/12
Filed: 1971-09-28
Abstract: 1401976 Velocity along a straight line MARCONI CO Ltd 23 Aug 1972 [28 Sept 1971] 45065/71 Heading G1A In a device for measuring the velocity of an object moving along a straight line a one or two sets of mirrors 1-10 or 1A-10A are arranged as shown to receive light from different parts of the line of travel and to reflect the light on to a corresponding common photo-sensitive device 14 or 17. Thus as the object being viewed moves along the line the amplitude of the output of the photosensitive device will vary and the frequency or repetition rate of the variations will be proportional to the speed of the object. Each of the sets of reflective elements may form one half portion of a dish, each set directing light to a common photo-sensitive device individual to that set. The mirrors may be part-cylindrical each forming an image in an aperture in front of the photo-sensitive device. The description derives a mathematical formula for use in positioning each mirror.

Title: Generating an image of a printed character
IPC: G06V30/164
Filed: 1975-10-31
Abstract: 1501660 Generating an improved image of a printed character INTERNATIONAL BUSINESS MACHINES CORP 31 Oct 1975 [27 Jan 1975] 45273/75 Heading G4R An improved image of a printed character is produced by forming a first amplitude function representing the amplitude of the intensity of each elemental portion of the character, e.g. by scanning, by transforming the amplitude function using a Fourier transformation to produce a second function, by operating on the second function using a filter function, forming a second amplitude function from the filtered function using a Fourier transformation and converting the second amplitude function into an image of the character.  Printed characters often contain defects such as comet tails (Fig. 1c) which have a periodic structure due to the structure of the inking ribbon. Such a character is scanned using equidistant rastering and the signal so produced is digitized. The function produced is Fourier transformed into a frequency function in which periodic features in the character due to the comet tails form local concentrations or singularities. The frequency function is multiplied by a filter function which removes these periodic features and is then transformed using a Fourier retransformation into an amplitude function. The transformations can be performed using programmed ditital computers.

Abstract: 1,130,652. Tert.-butyl alcohol. ATLANTIC RICHFIELD CO. 11 Oct., 1966 [23 Nov., 1965], No. 45489/66. Heading C2C. [Also in Division C5] Purification of tertiary butyl alcohol wherein the alcohol produced by oxidation of isobutane is hydrogenated in the presence of a hydrogenation catalyst to reduce the hydroperoxide and peroxide content to less than 100 p.p.m. The tertiary butyl alcohol is optionally contacted with aqueous alkaline earth metal oxide or hydroxide to produce alkaline earth metal formates which are removed preferably prior to the hydrogenation step. Conventional hydrogenation catalysts particularly of the transition series, e.g. nickel, platinum, palladium or ruthenium may be used providing a non-acid support, e.g. carbon or alkaline alumina, is used when formic acid and/or esters thereof, which may poison certain catalysts, are not removed prior to the hydrogenation. The optional removal of formic acid or esters thereof by the above treatment is carried out, optionally in the presence of 1 to 10 parts by weight of water, at temperatures from room temperature to the reflux temperature of the mixture. Tertiary butyl-alcohol containing diter-butyl peroxide and/or ter-butyl hydroperoxide is hydrogenated: (a) in the absence of formic acid or esters thereof using Raney nickel, nickel on kieselguhr or palladium on carbon or alumina (batchwise), and (b) in the presence of formic acid or esters thereof and other specified oxygen-containing impurities using platinum, palladium, ruthenium or nickel on carbon or nickel on alkaline alumina (continuously) to give a product having a peroxide content of less than 100 p.p.m. Other examples demonstrate that the hydrogenation of di-terbutyl peroxide does not occur readily using Raney nickel, nickel on kieselguhr, palladium or ruthenium on alumina or copper chromite if formic acid or esters thereof are present but will proceed if such contaminants are first removed by treatment with calcium oxide or hydroxide at room temperature or reflux.

Abstract: 1300809 Control systems for electrical soldering apparatus H KOBER 24 Sept 1970 [25 Sept 1969] 45495/70 Heading H2H Electrical soldering apparatus having soldering electrodes of carbon having a negative temperature coefficient is provided with means whereby the increase in current as the electrodes heat up is controlled. Elements to be soldered together are placed between carbon electrodes 1, 2 having a negative temperature coefficient and which are energized from an A.C. supply by way of a triac Tr, a current limiting resistor R 1  and a transformer 3. The supply to the transformer 3 is controlled by the triac Tr the trigger signal for which is derived from a circuit having a capacitor C 1 , resistors R 2 , R 3  and a break-over device D, one of the resistors R 3  being adjustable to control the firing angle of the triac. As the soldering electrodes 1, 2 warm up the volt drop across the resistor R 1  increases thus increasing the brilliance of a lamp L in parallel with the resistor R,. The light from the lamp L is arranged to fall on a photoresistor F such that an increase in the brilliance of the lamp due to an increased current caused by heating of the electrodes 1, 2 effects a reduction in the resistance of the photoresistor F. A capacitor C 2  charged by way of the photoresistor F is connected in parallel with the capacitor C 1 . Thus the de. crease in the resistance of the photoresistor F causes the firing angle of the triac Tr to increase thereby to decrease the current supplied to the transformer 3. A resistor R 4  and a manually operated switch 6 in parallel therewith is provided to affect the lamp brilliancy so that the apparatus can be adapted to the kind of soldering electrodes used with the apparatus.

Abstract: 1,160,515. Centrifugal casting machines. SHAHMOON INDUSTRIES Inc. 17 Oct., 1966 [23 Oct., 1965], No. 46403/66. Heading B3F. In a centrifugal casting machine for casting iron pipes a pouring mechanism is provided that comprises a boot -50 mounted on a pivot 52 and pivotable between an advanced position with its outlet end 46 received in a mould 30 and a retracted position, and a ladle 54 pivotally mounted on trunnions 56 and tiltable to pour molten metal into the boot 50. The mechanism is operated by a single actuator 60, e.g. an hydraulic cylinder and piston, that is connected at one end to the ladle and at the other end to the boot via pivoting levers 126, 134. Due to relative balance of the boot 50 about its pivot and the unbalance of the ladle 54 about its pivot initial movement of the actuator 60 advances the boot until stop 62 is registered and then the ladle 54 is raised. On lowering the ladle is initially lowered on to stop 66 and the boot is retracted until stop 64 is registered. The machine may comprise two collateral casting moulds 30 in which case a single actuator operates pairs of ladles and boots (Figs. 2 and 5, not shown). The actuator may be connected to frame part 90 to enable a ladle to be removed without dismantling the actuator. Similarly the boot 50 is mounted within a supporting frame. The boot 50 may be coated with graphite. The ladles may be weighed and coupled to an alarm to show when the metal has been poured. In the machine described (Fig. 1, not shown), a pair of shuttle cars (14) are movable along tracks (12) between a pouring station (20) a pulling station (22) and an oppositely mounted mould spraying station (26).
