Title: Pneumatic clutch control system for marine drive
IPC: F02D29/00
Filed: 1972-03-15
Abstract: 1340443 Reverse control FALK CORP 15 March 1972 [14 June 1971] 11990/72 Heading F2D A single lever 2, effecting pneumatic control of an engine throttle governor 9, and pressurization of forward and reverse air-inflated clutches 16, 17 in a marine reverse gear, is arranged so that over a first part of the lever travel in either direction from central neutral, the ahead or astern clutch 16 or 17 is slippingly engaged through a first engaging means by gradual increase up to a first pressure, and, during the further lever travel, is pressurized through a second means, e.g. a restrictor 48, at a programmed rate to a second pressure, whereafter the second means is actuated to complete full pressurization; together with control of the engine throttle governor 9 to maintain engine idle until clutch pressure reaches a third value, whereafter graduated pressure from the first means is supplied to the throttle governor 9 for engine speed regulation. The lever 2 actuates a throttle valve 23 which supplies full line pressure 3 to one or other of two pilot pressure lines 5, 6, during its first five degrees of movement, to actuate a selector valve 41 determining the supply of engaging pressure 39 to the ahead or the astern clutch 16, 17. Throughout the whole lever movement the throttle valve 23 supplies graduated pressure responsive to lever travel to a line 4 which pressure is reproduced in a line 30, with increased flow capacity, by a relay valve 26 fed directly by the main 3. Over the first thirty degrees of lever movement, the proportionate pressure 4, 30 feeds the clutch supply line 39 through a master valve 32 until a first pressure (1À8 kg./cm.<SP>2</SP>) is reached in the line 4, 30, such pressure then actuating the master valve 32 at 38 to communicate the clutch supply line 39 with a master valve port 33, fed directly from the main 8 through the restrictor 48 for pressure increase at the programmed rate, until clutch pressure reaches the second value (3À2 kg./cm.<SP>2</SP>), whereupon it acts through a shuttle valve 60 and line 66 to shift a boost valve 49, connecting the master valve port 33 directly to the main 8 for unrestricted clutch inflation, during which, when the third pressure (4À2 kg./cm.<SP>2</SP>) is reached, it acts through lines 66, 73 to open a valve 67 supplying lever-controlled graduated pressure 4, 30 to the engine throttle governor 9 for regulated throttle control during the further travel of the lever 2, the engine remaining at idle up to this time.

Title: Method and apparatus for adjusting the valve tappet clearances in internal combustion engines
IPC: F01L3/24
Filed: 1975-03-21
Abstract: 1485664 Adjusting tappet clearances in I.C. engines FORD MOTOR CO Ltd 21 March 1975 [11 April 1974] 12004/75 Heading G1M A method of adjusting the tappet clearance of a valve 2 includes connecting a compressed air supply 7 to a spark-plug hole 3 of a cylinder 1 to build up pressure therein, and starting with the valve 2 closed, turning a valve tappet adjuster screw 5 by means of a tool handle 17 until the pressure in the chamber 1 has fallen by a pre-determined amount. As the handle 17 is operated, the load on a pressure sensor 20 causes it to supply an electric signal to close a valve 15 and the lower side of a piston 12. When the pressure drops to the required value due to the valve being opened further the pressure on the upper side of the differential piston 12 is correspondingly reduced so that the piston moves upwardly against spring-bias to close a switch 16 and de-energize an electromagnetic clutch 19 in the torque drive thus automatically halting the screw adjustment. The tappet clearance or gap may then be set by turning the adjuster back through a specific angle. The gap may also be set by using a feeler gauge 23 slightly greater in thickness than the required gap, the thickness being such that when the predetermined pressure drop occurs the valve is slightly open and the tappet is adjusted to a slightly larger gap which closes a little when the valve re-seats.

Abstract: 637,429. Rotary pumps and compressors. MALONE, J. F. J., and MALONE, R. May 4, 1948,No. 12251. [Class 110(ii)] A flexible-chamber type of pump or compressor comprises a number of tubes whose side walls are moved relatively and in sequence so that enclosed spaces 33 move transversely, Fig. 1, from right to left. The walls 26, 27 which may be actuated by reciprocating bars 24, 25, cams, or electromagnetically, extend from inlets 32 in manifolds 34, 48 to similar, outlets and manifolds 49. The spaces 33 may expand or diminish in size after leaving the inlet ports and before reaching the outlets. This is effected by varying the relative degree of eccentricity of different eccentrics 10. As shown, the apparatus is used in refrigeration and comprises a combined compressor and expander. The bars 24, 25 are moved by eccentrics 10, on shafts 7, 8, with connecting pieces 11 which cause reciprocating movement of bars 13, 14 towards and away from,each other. The bars 13, 14 actuate vertical rods 17, 18 which act through springs 20 and projections 21a and cause the movement together or apart of the cellulose-impregnated canvas sheets 26, 27. The latter act through canvas belting which prevents contact between the sheets and the bars 24, 25. The sheets 26, 27 are secured with air-tight joints at their side edges where they are supported in rectangular channels 28. Two banks of compressor chambers, Fig. 2, have their actuating rods 17, 18, 45, 46 connected by pivoted links, as shown. Pivoted shoe-like stiffeners 50, Fig. 1a (not shown), may be arranged between the canvas belting walls. Further reinforcements may be used for the canvas elements or flexible thin metal sheets may be used instead. The elements may be arranged in drum form, the transverse bars being actuated by rollers. The elements may be formed from cellulose or cellulosewoven sheet.

Filed: 1923-05-09
Abstract: 219,424. Jackson, W. J. Metlersh-, (Geometric Tool Co.). May 9, 1923. Screwing die-heads.-In self-opening screwing die-heads of the type in which chasers are operated by a spring-controlled cam ring which is released to open the die by means of a spring-restored tripping device, the latter swings about an axis at right-angles to the die-head axis and carries a bolt for locking the cam ring, and an independent spring plunger, for resetting the tripper. extending into a recess in the head. The chasers are operated by eccentric projections 16 on a cam ring 15 which is maintained in the open position by a spring 19. In operation, the die-head is secured in a screwing-machine by a shank 49, and as the chasers cut, the head is drawn forward against a spring 50, until a nut 45 on a rod 44 pivoted to a flange of the shank engages a tripping lever 33 and rocks it about pivots 34 so as to disengage a bolt 36 from an adjustable block 39 on the cam ring, which is then rotated by the spring 19. The head is returned by the spring 50 and the bolt 36 is reengaged with the block 39, after the cam has. been rotated by hand or by a stop, through a restoring spring 57 mounted independently of the bolt. The block 39 is adjusted relatively to the cam ring for varying the die pass by two. tangential screws 41 engaging a pin 40, Fig. 9. The opening of the die is limited by a radial plunger on the cam ring engaging a stop 29 on the head, the plunger being retractable against spring action to allow for removal of the chasers. A back plate 21 serves to keep the cam ring and spring in position and carries a flange on which the tripping lever 33 is pivoted. The head is prevented from disengaging from the shank by two bolts 62.

Filed: 1965-03-24
Abstract: 1,107,186. Electric calculating apparatus. HOLLANDSE SIGNAALAPPARATEN N.V. 24 March, 1965 [27 March. 1964], No. 12543/65. Heading G4A. Successive trains of pulses, especially for controlling electronic digital data apparatus, are monitored to see whether the number of pulses in each train is divisible by n. The trains are applied in true and inverted forms to leads 100, 101 and so to set and reset inputs of a ring counter shown schematically as comprising stages 113-116. Monostable circuits 106, 107 normally operate alternately so that OR gate . 108 remains open as long as trains 100, 101 persist. When gate 108 closes at the end of a pulse train its decreased output operates a differentiating circuit 112 to start the time base circuit of a cathode-ray tube. Each time stage 114 of the counter is set it deflects the beam of the cathode-ray tube to produce a blip. The blip remains stationary if successive trains are divisible by n. In a modification the counter stages are divided into groups which control timecontrolled gates. If the trains are not all divisible by n the terminating stage moves from one group to another to bring up an alarm.

Title: Improvements in or relating to the production of gallium
IPC: C22B58/00
Filed: 1963-03-29
Abstract: In a process for recovering gallium from liquors containing sodium gallate and sodium aluminate, sufficient active finely divided aluminium is added to displace the gallium from the sodium gallate and to alloy therewith to form an Al-Ga alloy which may be separated by filtration or centrifuging.  The Al may be ground Al and is preferably ground in the presence of aluminium alkyls in the absence of air and moisture.  The gallium may be separated from the alloy by chlorinating the alloy to obtain a trichloride mixture from which the GaCl3 may be selectively extracted, forming alkali metal gallate therefrom and then electrolysing this to deposit Ga.  An alternative method is to use the alloy as the anode in an electrolytic cell using an organo-aluminium complex salt electrolyte, the gallium being recovered from the anode residues by further electrolysis. Fairly pure liquid gallium may also be obtained by treating the alloy with alkali liquor or dilute acid.  Specifications 981,685 and 1,001,482 are referred to.
