Title: Actuation device for the synchronous engagement of a coupling mechanism for selfpropelled diesel vehicles
IPC: F16H63/40
Filed: 1965-07-09
Abstract: 1,056,368. Change-speed control. SOC. ANON. FRANCAISE DU FERODO. July 9 1965 [July 9 1964], No. 29291/65. Heading F2D. In order to facilitate gear changing the transmission of a diesel-engined vehicle is arranged so that initiation of a gear change disengages the main clutch and causes the fuel injection pump to operate at a high or low rate according to whether the driving shaft is rotating at a lower or higher speed than the driven shaft and at the same time the connection of the accelerator pedal with the fuel pump is rendered ineffective. Transmission details.-As shown a friction clutch A is associated with an hydraulic torque converter 15, a solenoid control valve 80 being provided. In addition a diaphragm capsule 88 is controlled by a valve 90 responsive to the difference in speed between the driving and driven shafts B, D, the capsule being pressurized when shaft B rotates slower than shaft D to close an electric switch N. A normally open switch K on the gear change lever 20 is closed when the driver grasps the lever. A further switch P is closed when the gear is in neutral and opened when a gear is engaged. The fuel pump control rod 150 is connected to the accelerator pedal 13 by a link 155. Operation.-With the gear in neutral switch P is closed to connect solenoid 81 of control valve 80 to a battery through a circuit H, so that the clutch chamber 71 is put under pressure to hold the clutch disengaged. When the driver grasps lever 20 to initiate a gear change the switch K is closed to energize a relay coil 26 which operates a contact arm 27 to de-energize a second relay coil 38, the arm 40 of which engages a contact 41 to energize a circuit J including a solenoid 56 which lowers an armature attached to pedal link 155, which is thus drawn down to a position in which it renders pedal 13 inoperative upon fuel pump rod 150. A condenser 37 in parallel with relay 38 ensures a slight delay in operation after the closing of switch K. If the switch N is closed due to driving shaft B rotating slower than driven shaft D, a solenoid 164 in a circuit L is energized to hold the fuel pump rod 150 in the high injection rate setting, but if the switch N is open due to shaft B rotating faster than shaft D a spring 161 holds the pump rod 150 in the low speed or idling position. Upon release of lever 20 with a gear engaged the switch P is opened to allow re-engagement of clutch A. In a second arrangement, Fig. 3 (not shown), a centrifugal clutch replaces the hydraulic clutch and torque converter.

Title: Water heating apparatus
IPC: F24H1/44
Filed: 1964-07-14
Abstract: 1,077,106. Water heaters. A. DE F. HOLDEN. July 14, 1964 [July 16, 1963], No. 29437/64. Headings F4A and F4K. In a water heating apparatus the final stage of heat transfer is accomplished through direct radiant heating of water passing a radiant heating element. In the form shown a luminous wall gas firing unit 10 is vertically mounted at the side of the apparatus. The water to be heated enters the apparatus through inlet pipe 20 and thereby to the uppermost pan 18 of a series of substantially horizontal pans alternatively offset from each other and each with one end adapted to provide an overflow into the next lower pan. The water flows back and forth across the pans and down a vertical screen 27 suspended from the end wall 26 and in front of the luminous highly radiant firing face 13 of the gas firing unit 10, and then into the hot water reservoir 16 in the bottom of the apparatus. The combustion gases rise towards the exhaust flue 28 preheating the water in the pans. A series of air tubes 29 may be installed in a compartment 30 at the top of the apparatus above the water pans to condense any water vapour and provide optimum furnace efficiency. The apparatus may serve a combined heating and hot water supply system. A pump 35 delivers hot water to the radiator 17, the cooled water re-entering the apparatus at the inlet pipe 20, and a pump 33 delivers the hot water for general use. To keep the water level in the reservoir constant a ball valve 31 controls an inlet valve 32. A pump 34 may be provided to re-circulate water in order to maintain a predetermined temperature of the water in the reservoir.

Abstract: 779,273. Automatic voltage control systems; alternators. BRUSH ELECTRICAL ENGINEERING CO., Ltd. Oct. 13, 1954; No. 29520/54. Classes 35 and 38 (4). In a voltage control system for self-excited alternator of the kind in which the field current is controlled by a saturable reactor, build-up at starting is ensured by temporarily energizing auxiliary A.C. windings on the saturable reactor. The field 2, Fig. 1, of the alternator 1 is selfexcited via a, metal rectifier 36 and a transductor 35 which is controlled by the output of a voltage detector 5, Fig. 2 (not shown), of the kind disclosed in Specification 740,376, via a low-pass filter 7, Fig. 7 (not shown), and a magnetic amplifier 4, Fig. 4 (not shown), of the kind disclosed in Specification 752,279, [Group XXXIX]. A low-pass filter 6, Fig. 6 (not shown), is added between the detector 5 and the line, and an anti-hunting signal is derived from a transformer 9. To assist buildup when starting, a no-volt relay 47, Fig. 5, energizes the auxiliary A.C. windings 44, 45, 46 on the transductor 35 directly from the output terminals of the alternator. The relay may be replaced by a non-linear resistor in series with the windings, and the build-up may be effected in stages by multiple relays.

Abstract: 538,753. Mosaic screens. STANDARD TELEPHONES & CABLES, Ltd. Nov. 7, 1939, No. 29558. Convention date, Nov. 7, 1938. [Class 39 (i)] A photo-electric mosaic screen is made by coating one side of a sheet of mica or other insulating material with a light sensitive emulsion. and exposing to light only those parts 14, Fig. 2, between isolated areas 12, the exposure being controlled either directly by a frame placed on the screen or by an optical image focused on the screen. The emulsion is developed leaving the areas 12 exposed and silver is vaporized on to the screen, which is subsequently heated-it may be during the normal preparation process of the cathode ray tube wherein it is mounted. This cracks the hardened developed emulsion 14 and separates it from the silver areas 12, which are subsequently photo sensitized with caesium. The mica screen has the usual metal backing of liquid gold or silver or of aluminium. If desired the developed emulsion 14 may be dissolved away. In a modification the isolated areas 12<SP>1</SP>, Fig. 4, are light exposed and the emulsion remains thereon to give cracked surfaces between the caesiated silvered areas 14. The Specification as open under Sect. 91 also describes a modification wherein an emulsion coating is applied to an aluminium surface evaporated on to a glass base, the emulsion being exposed to form a desired pattern the.'unexposed parts being removed during development; this screen has good secondary emitting qualities. Further processing of this screen may consist of spraying or rubbing ink with a high carbon content on the exposed aluminium; or ink in a carrier may be applied and in part washed off. The result is that the desired pattern is coated with carbon of low secondary emission separated by metal with higher emissive properties. This subject-matter does not appear in the Specification as accepted.
