Abstract: 245,318. Purvis, W. J., and Taylor, C. W. March 30, 1925. Hunting and differential switches.-In a coinfreed machine in which the actuating movement is effected by an electric motor, the motor is controlled by a switch comprising two co-axial rotative members designed to be rotated in the same direction alternately to make and break the circuit. A shaft a, Fig. 1, for actuating a ticket delivery or other mechanism is driven by an electric motor shaft in alignment therewith through a friction clutch comprising driving and driven members c, d and friction rollers e. The electric motor is controlled by a switch comprising two metal rings k, l', Fig. 5, which are rotated in the same direction alternately to make and break the circuit, the ring k having a pair of contact strips k<3> to make contact with a pair of brushes l on the ring l<1>.

Title: An improved injection-quantity regulator for separately ignited injection internal combustion engines that operate at different heights, for instance aircraft engines
IPC: F02D1/00
Filed: 1944-05-05
Abstract: 576,886. Regulating. SOC. ANON. A.. SAURER. May 5, 1944, No. 8551. Convention date, June 12, 1943. [Class 7 (vi)] In an aircraft &c. engine of the kind having direct fuel injection with separate ignition, the quantity of fuel delivered by the injection pump is regulated in dependence upon the difference between the pressure of the charging air in front of the cylinder and the critical pressure corresponding to this pressure, the critical pressure being defined as the pressure which, on the exhaust side of an orifice or at the throat of a venturi nozzle produces maximum discharge through the orifice or nozzle when the charging air pressure acts on the admission side. In the air inlet passage 1, Fig. 1, the pressure beyond the throttle 2 is communicated by a passage 3 and pipe 10 to one side of a diaphragm 13 in a closed chamber 12, the opposite side of the diaphragm being exposed to the critical pressure obtaining in a nozzle 4 which is arranged at the end of the passage 3 and opens into a chamber 5 maintained at low pressure by a suction pump 7. The control rod 16 of the injection pump is connected by a rod 15 to the diaphragm 13. The nozzle 4 may have a divergent mouth opening into the chamber 5 in which case a pressure higher than the critical pressure suffices in the chamber. To compensate for atmospheric pressure, a piston may be mounted on the connecting rod 15 and slide in an openended cylinder in the wall of the chamber 12, the atmospheric pressure opposing the pressure on the diaphragm created by the nozzle 4. As shown in Fig. 4, nested venturis, 19<1>-19<111> replace the suction pump 7 and the nozzle 4 opens into a chamber 5 communicating with the innermost venturi 19<111>.

March 15, 1957 [March 20, 1956; Jan. 17, 1957], No. 8653/57. Class 41. Titanium or zirconium is extracted from an alloy containing one of these metals and Al, U, Mn, Cr or Fe by electrolytic refining in a molten bath containing one or more alkali or alkaline earth metal halides, wherein the metal to be refined is used as the anode and wherein the bath contains a titanium or zirconium subchloride, and additions of the alloy are made to the anode during electrolysis, as titanium is deposited at the cathode. Specified alloys are those of titanium with iron, iron and silicon, iron and chromium, aluminium, aluminium and vanadium, aluminium and manganese and preferably do not contain oxides or nitrides in excess of 8% by wt. In examples, the anode' alloy preferably containing 65 to 95% of titanium or zirconium is in the form of suaall lumps held.in a basket, suspended in a molten mixture of NaCl and about 3% of TiCl 2 ; a voltage of up to 2 V. is applied, and fresh alloy is added to the anode basket when the ratio of deposited metal at the cathode to the original charge at the anode rises to 22%. In the case of alloys containing small amounts of Al, Mn, or V (e.g. up to 5% of these) the ratio figure may be allowed to rise to 40 to 50%. The alloy to be treated may be first tested for solubility in the molten electrolyte without. applying an electric current; details are specified.

Title: Colour imaging device

Filed: 1976-03-05
Abstract: 1527918 Television systems EASTMAN KODAK CO 5 March 1976 [5 March 1975] 08997/76 Heading H4F A colour imaging device comprises an array of three types of light-sensitive members which are respectively sensitive to different spectral regions and are arranged in respective repeating patterns. One type of member alternates with a member of another type in two perpendicular directions and has a higher frequency of occurrence than that of either of the other types. The members may be CCD or CID devices. They may be inherently responsive to different spectral regions or may be overlaid by a filter matrix having differently transmissive regions in 1:1 relationship with the light-sensitive members. In one arrangement the most frequently occurring members Y are green-sensitive, Fig. 1B. In alternate rows the green-sensitive members alternate with red-sensitive members Cl and in the remaining rows they alternate with blue-sensitive members C2. In another arrangement, Fig. 6 (not shown), some of the members C2 (blue) are replaced by members C1 (red) in recognition of the fact that the human eye discerns blue detail less well than red detail. In use of the array shown, information is read from a row to a shift register which passes it in serial form to a switching network, e.g. as Fig. 5 (not shown). The network separates the green information from the red and blue and, by use of half line frequency switches (56) and a one-line delay register (54), delivers serial red, green, and blue information signals simultaneously on respective outputs to a unit which converts the signals to a format suitable for use in broadcasting.

A method of screening dry or moist granular or powdery material consists in feeding the material on to the surface of a vibratory screen and causing the depth of the bed of material on the screening surface to increase or to remain constant as the material progresses from the feed end to the discharge end of the screen. It is stated that by this method the average throughput of the undersize particles through the screen is more than double that obtained by known processes thereby considerably reducing the amount of under - size particles entrained in the oversize particles. Formulae are given for calculating what speed the material should have at different points along the screen for the depth of the material to increase or remain constant. In one form of apparatus. Fig. 5, the screen surface is subdivided along its length into sections 1-10 having inclinations relative to the horizontal decreasing from 35‹ at the feed end to 0‹ and increasing to 5‹ at the discharge end. Mechanisms 21-30 mounted on the frames of the screen sections impart independent and different rectilinear or elliptical vibratory movements to the sections. The material to be screened is fed from a conveyor 41, the undersize falls down chutes 31-40 onto a conveyor 42 and the oversize, with some entrained undersize, falls on to a conveyor 43. Dimensions are given.
