Title: A supercharged internal combustion engine
IPC: F02B29/04
Filed: 1963-01-02
Abstract: 1,033,181. Air-cooling heat exchangers. KLOCKNER - HUMBOLDT - DEUTZ A.G. Jan. 2, 1963 [Jan. 11, 1962], No. 239/63. Heading F4S. [Also in Division F1] A device shown, for cooling supercharged air as it flows into an I.C. engine (not shown) is bolted to the engine by flanges 14 on its supercharging-air outlet manifold 15, and consists of a row of cross-flow heat exchange units 7 (see Fig. 1, not shown) in which the supercharging air is cooled either by air from a blower 12 flowing through the units by way of inlet and outlet ducts 10, 11, or by water passing through the units by way of header boxes 13 (Fig. 5, not shown), bolted to the units 7 in place of the ducts 10, 11. The supercharged air may make a plurality of passes of successively reducing cross-sectional area through the units 7 before reaching the outlet manifold 15 leading to the engine. When ambient air is used as the coolant it may, after passing through the superchargedair cooler, be used directly to cool the engine if the latter is air cooled, or as a coolant for the engine radiator when the engine is water cooled.

Title: Automatic weighing system and methods
IPC: G01G13/28
Filed: 1974-01-03
Abstract: 1433101 Automatic control of powder flow HAYSSEN Mfg CO 3 Jan 1974 [5 Jan 1973] 00245/74 Heading G3R [Also in Division G1] An automatic feed weigher comprises a weighing machine 19, a bulk feed conveyer 15, a dribble feed conveyer 17, switches BS and DS on the weighing machine which operate at predetermined weights to terminate the bulk feed and the dribble feed respectively and an arrangement which defines a time band starting at a predetermined time from the start of a weighing cycle (dribble band in Fig. 2) and which, when the switch DS operates to terminate the dribble feed at a time outside the dribble band, automatically applies a correction to the rate of the bulk feed. Powder from a hopper 11 is supplied to conveyers 15 and 17 by a conveyer 13, conveyers 13, 15, 17 being vibrator conveyers. Conveyer 17 is vibrated by device 31 controlled by an adjustable autotransformer 43, power to which is supplied through thyristor 45. Conveyers 13, 15 are vibrated by devices 27, 29, both of which are controlled by an adjustable autotransformer 33 supplied with power through a thyristor 35. Autotransformer 33 is adjustable by means of a servomotor 39. A motor 47 drives cams 49A to E which actuate switches LSA-LSD, DPS at set points in each weighing cycle. Switches LSA, LSB, define a bulk band, switches LSC, LSD define the dribble band, and switch DPS operates a dump solenoid 23 at the end of the cycle to empty the weighing machine. At the beginning of a weighing cycle, power is fed to vibrating devices 27, 29, 31 so that powder is passed to weighing machine 19 by both the bulk and dribble conveyers 15, 17. If the time at which switch BS operates is not within the bulk band, one of the lamps SL1, SL2 is lit up for a short period to indicate that manual adjustment of the rate of delivery is required. If the time at which switch DS operates is not within the dribble band, the logic circuit causes the servomotor 39 to operate in the appropriate direction for a preset time determined by timer 55 in order to bring the time at which switch DS operates towards or into the dribble band. Automatic adjustment of the dribble conveyer 17 may also be provided.

IPC: F02D15/00
Filed: 1949-01-05
Abstract: 661.390. Varying cylinder clearance. PETIT, G. Jan. 5, 1949 [Jan 28, 1948], No. 282/49. Class 7(ii) The compression ratio of a multi - cylinder engine is regulated by pistons 3 working in chambers 2 and connected to a crankshaft 6 enclosed with the pistons in a housing 4 containing oil under pressure for actuating the  pistons. A hollow arm 23 connected to part of the crankshaft external of the housing has a valve, such as a spring- loaded ball 8, which controls the flow of oil from the housing via the  crankshaft duct 7 and is operated automatically according to the variation of intake manifold pressure by means which may comprise a cam 12 moved about the crankshaft axis by a rod 16 connected to the spring-opposed diaphragm 19 of a gauge communicating with the manifold. In operation, with an increase in manifold pressure, the follower 11 is liberated during upward movement of the cam, and ball 8 under the action of spring 9 closes the arm opening 25 so that the oil pressure in the housing increases to move the pistons and decrease the compression chamber volume. The arm rises until the follower again engages the cam to open the valve, and oil escapes from the housing through conduits 14, 15 to the oil sump so that the pressure in the housing is decreased and the chamber volume increased. A pump 22 feeds the housing via a conduit 13.. In a modification, the cam has a lug acting on the ball and a shoulder to engage and accelerate the downward movement of the arm.

Abstract: 327,127. White, A. E., (Delco-Remy Corporation). Sept. 22, 1928. Divided on 327,108. Spray carburettors. - Fuel is delivered into a space in which only a static suction is maintained, the entering air not passing directly in contact with the fuel discharge orifices. Primary carburettors 100, 101, 102, Fig. 3 deliver rich mixture through conduits 112, 113, Fig. 1, to branches 12, 11, 13 of an air manifold 10 having an admission opening 17. The carburettors are formed in a block 90, Fig. 3, and each has a high-speed fuel orifice 98, Fig. 2, and a low-speed 99, these orifices receiving fuel from distributing channels 93, 94. Air is admitted to each carburettor through a bush 105, Fig. 3, which extends axially beyond both fuel orifices so as to prevent the air stream from flowing in contacts therewith. The fuel is discharged into the annular space between the bushing and the carburettor wall. The mixture is delivered to the throat of a Venturi 110 in each branch, and between each Venturi and the cylinders a throttle 125 is located. A tube 150 serves to equalize the pressure in the three branches. Specification 327,107 is referred to.

Filed: 1939-01-04
Abstract: 522,327. Stripping tobacco leaves. HANSEN, N. Jan. 4, 1939, No. 298. [Class 130], Tobacco leaves are held against apertured panels 8 at the top of casings 3 by suction transmitted through pipes such as 4 from a fan 6, while rotary disc knives 21 are moved over fixed knives 10 to cut out the stems which fall down a shoot, not shown. After the stems have been removed the panels 8 are turned through 180 degrees and flaps 11 are turned through 90 degrees to enable the leaf-halves to be deposited on stacks carried on counterweighted verticallyslidable supports 12. The knives 21 are carried on shafts 18 which are supported in the forked end of a lever 17 and are rotated by rollers 26 which run over the panels 8 as the lever 17 is actuated by a foot-pedal 31. Spring-pressed rollers 65 hold the knives 21 against a curved member 20 which tilts the knives on their shafts to bring their cutting edges against the edges of the knives 10. The lever 17 is returned to its initial position by a foot-pedal 31 and as the knives 21 approach the end of the panels 8 the notched end of a lever 36 engages an abutment 38 on a lever 37 to release the lever 37 from a clutch member and.free a spring-pressed bolt which moves into engagement with a clutching element to permit a shaft 42 to be rotated by a driving motor. Cams 44 then operate pivoted levers 45 which, through chains 47 held against sprockets 50 by springs 48 rotate the panels 8 around axes 8<SP>1</SP> through 180 degrees, and cams 50 on the axes 8<SP>1</SP>, through linkage 52, 53 rotate the flaps 11 through 90 degrees. The clutching elements are disengaged when an abutment on the machine frame engages an inclined surface on the arm 36.

Title: Process for the production of phosphorus sulphochloride
IPC: C01B25/10
Filed: 1951-01-05
Abstract: Phosphorus sulphochloride is prepared by the reaction between phosphorus trichloride and sulphur, catalysed by the presence of activated carbon, preferably at temperatures from 80-125 DEG C under reflux and atmospheric pressure.  Carbon activated under reducing conditions with potassium sulphide is preferred.  A quantity of phosphorus sulphochloride from previous operations is preferably added initially to the reaction mixture to raise the boiling point thereof and accelerate the reaction.  The product is separated by distillation.  A statement of prior art refers to the production of phosphorus sulphochloride by the reaction between phosphorus trichloride in the vapour phase and liquid sulphur at 150-180 DEG C, and also to the use of alkalies or alkali metal sulphides or polysulphides as catalysts.
