Abstract: 1,218,732. Electro-plating. D. P. A. CULBERT. Dec.1, 1967 [Sept, 2, 1966], No.39344/66. Heading C7B. A metal or alloy is electro-deposited from an aqueous solution in which the metal or each metal component of the alloy is present as a co-ordinate complex with a chelated compound formed by reaction of orthoboric acid and an organic compound having oxygen-containing groups in positions such that they can effect chelation with the boron atom. Examples of such organic compounds are salicylic acid, catechol, glycerol, mannitol, invert sugar and certain (unexemplified) diols. A buffer such as a phthalate, succinate, furoate or a phosphate, e.g. KH 2 PO 4 , may be included in the bath. Specified complexing metals are gold, copper, nickel, silver, platinum and palladium. Examples are given of baths for depositing gold, bright gold alloys containing as brightener metal copper or palladium, and copper-nickel alloy. It is stated that the rate of deposition depends on pH, decreasing with increase of acidity. In the examples the gold is provided by potassium gold cyanide, copper as an ethylene diamine complex or as copper acetonylacetonate, nickel as an ethylene diamine complex, and palladium as palladous glycine and these compounds react in solution with boric acid and glycerine, invert sugar, or mannitol being added to the aqueous solutions to form the co-ordination chelate complexes.

Title: Cold start fuel/air mixture supply devices for internal combustion engines
IPC: F02N99/00
Filed: 1974-09-11
Abstract: 1497792 Spray carburetters ZENITH CARBURETTER CO Ltd 10 Sept 1975 [11 Sept 1974] 39665/74 Heading F1H The air passage in the body 12 of a starting carburetter 11 has an outlet 58A for connection to an engine inlet manifold and an inlet 82 controlled by an air valve 80 biased towards closing by a spring 86 in opposition to forces produced due to the suction in a chamber 88 upstream of the throttle valve and acting on the air valve and due to suction acting on the end-face of a plunger 83 from the air passage downstream of the valve 18 or a space separately connected by a conduit (98), Figs. 6 and 7 (not shown), to the intake manifold. A metering needle 33 connected for movement with the valve 18 controls fuel flow to the chamber 88 and the position of the valve 18 in response to the suction in the air passage is determined by a peg intermediate the pegs 40 and 43 on a lever 70 pivoted on a pin 42. The peg 43 engages a flange 48 on a rod 46, positioned by a wax filled capsule 45 subject to a flow of engine cooling liquid, which determines the angular position of the lever 70. When the engine is at its normal working temperature the peg intermediate the pegs 40, 43 which is engaged by the arm 37 permits the needle valve sealing ring 34 to seal the orifice 61 and prevent fuel flow. The load provided by the spring 86 may be adjusted by variably screwing the spring supporting plunger cylinder 84 into the body 12 or the spring may engage a nut (89), Figs. 4 and 5 (not shown), on the cylinder (84A). The nut (89) is prevented from rotating by a peg (91) and rotation of the cylinder (84A) adjusts the axial position of the nut on the cylinder. The plunger (94, Fig. 7), associated with the air valve 80 may be biased into engagement therewith by a spring (99), the spring 86 acting against a flange (103) on a tube (95) in which the plunger is mounted. In this arrangement the suction acting on the end of the plunger (93) remote from the valve 80 opposes the force of its biasing spring (99) and the plunger may be withdrawn from engagement with the valve. The fuel inlet passage 27 communicates with the float chamber of one of a pair of main carburetters (23) Fig. 3 (not shown), each communicating with respective manifold branches. The manifold branches are connected by a balance pipe (15, Figs. 3 and 6), to which the outlet 58A is connected. The body 12 has a cover (23, Figs. 3 and 6), defining a chamber communicating with the main carburetter air cleaner (102) and the inlet 82.

Abstract: 1,079,614. Rope railways. LORRAINEESCAUT. Oct. 1, 1964 [Oct. 28, 1963], No. 40033/64. Heading B7L. A method of changing the counter-weighted carrying cable 1 of a ropeway comprises supporting the counterweights and taking up the rope tension by winches, cutting the ends of cable 1 and joining the ends to a take-up cable on drum 7, Fig. 2, and to a new cable on drum 6 by butt-welding, winding the old cable on to drum 7 which is driven by an air-engine supplied from petrol or oil-driven compressors, the cable having been raised above supports on pylons 4 by rollers 5, separating the old and new cable and attaching the counterweights, Fig. 1 (not shown), whilst the new cable is held tensioned by the winches acting on cable clamps. Drum 6 is equipped with brakes to maintain tension in the cable. In Fig. 4, an endless cable 8 normally passing over pulleys 9, 10, 11, 12 is driven by pulley 9 from motor 13 and is tensioned by weight 14; buckets 15 can be coupled to and uncoupled from the cable at stations 16, 17. To renew the cable, the cable 8 is cut in the region ASB after tension in this region has been relieved by clamps at A and B; a new cable from drum 18 is attached to one end of the old cable, the other end being connected to a take-up cable on drum 19 on to which the old cable is eventually wound. Take-up is effected by driving the drum 19 and the cabledriving pulley 9 in synchronism and unwinding of drum 18 is controlled by braking to maintain the counterweight 14 between two set height limits.

Abstract: 1367188 Automatic gain control INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS 29 Aug 1972 [1 Sept 1971] 40059/72 Heading H4R In an automatic gain control circuit a pilot signal Pe is added to the signal E applied to the controlled gain amplifier 1, and removed from the output of the amplifier and compared in 5 with a reference voltage Vo whose value changes as a function of time. The difference voltage is integrated, at 6, and controls the amplifier gain. The reference voltage variation follows a curve formed by a succession of straight line sections of varying slope, and may be programmed with time or controlled according to the output level of the wanted signal. As described the signals E may be from a geophone or a sonar device and the reference voltage can be derived from a store 9 of digital binary numbers fed at predetermined intervals to increment a counter 10. The counter output is fed to a d to a converter 11 to provide a stepped output signal V B . The stepped signal V B  is applied to an integrator 12 to produce the reference voltage which comprises a number of straight line portions, the slope of each of which depends on the digital number in the counter 10 at that time. In an alternative arrangement the signal fed to the counter 10 is controlled by the level of the wanted portion of the output voltage of the amplifier 1 relative limiting values so that the counter is incremented, or decremented, whenever the output level varies beyond predetermined limits. The arrangement can operate on either the peak or average level of the output signal. Gain variation is produced by a potentiometer having a photo-resistive device, the source to drain impedance of an f.e.t., or a Hall effect modulator.

Abstract: 1326931 Photographic colour printing CIBA-GEIGY A G 26 Aug 1970 [28 Aug 1969] 41137/70 Heading G2A The spectral composition of a colour printing light beam # 0  is controlled by comparing the spectral composition of the beam before and after passage through a colour negative positioned at 5. The integral density of the negative can thus be assessed irrespective of fluctuations of the light source or filters. A light source 1 is positioned within a number of cold light mirrors 9 and a heat filter 10. The beam passes yellow, magenta and cyanogen filters 2, 3, 4 which can be swung into the beam to a selected extent by drive motors 11, 12 and 13. The beam is blended or mixed by passage through mirror tunnels 14, 16 interconnected by a pyramid 15 of material with low diffusion capacity to illuminate a ground glass screen 17. Printing light intensities # 0 , # 1  are measured using fibre optic light guides 19, 20a, 20b, 21 and 22. The guides terminoate opposite a photo-cell 24 in front of which a disc 25 containing regions of different coloured filters is rotated by a motor 23. In addition, the photocell receives a signal periodically from a reference lamp 32. The thus seven successive outputs from photo-cell 24 are applied to a logarithmic converter 34, which is adjusted by comparator 42 according to reference light source 32, and thence via a distributor 35 to stores, e.g. 37, 38 for the blue component. A blue difference signal D KB  is produced at a summation stage 44 and the difference signal after various corrections is applied to motor 11 controlling the position of yellow filter 2 and to a blocking stage 71 which releases an exposure timer 74 only when the difference signal is below a certain threshold value. Timer 74 controls the operation of a shutter 7 and is fed with a signal from a summation stage 64 representative of the overall brightness of the printing beam. Stages 58, 54, 55 provide corrections to the measured signals for manual correction, negative parameters and printing material parameters respectively. Stage 47 adjusts the slope of the print material characteristic to take account of the Schwarzchild effect and development conditions, and stage 45 permits undercorrection if the negative has a colour dominant or colour cast.
