Abstract: 1,240,518. Combustion chambers. TOYOTA CENTRAL RESEARCH & DEVELOPMENT LABORATORIES Inc. Nov. 6, 1968 [Nov. 18, 1967], No.52555/68. Heading F1B. An I.C. engine cylinder is provided with an auxiliary combustion chamber 21, Fig. 1, communicating through at least one small opening 22 with the main combustion chamber 4 and connected to the carburetter A via a tube 25. During the suction stroke with the engine operating at no-load, i.e. with the throttle valves 11, 12 in the position shown, additional fuel-air mixture is drawn into the main combustion chamber 4 via the tube 25 and auxiliary combustion chamber 21, thereby scavenging residual exhaust gases from the latter and allowing complete combustion of the mixture therein on ignition by spark-plug 23. The combustion flame spreads through opening 22 into the main combustion chamber to produce complete combustion of the contents, even though the mixture therein is substantially diluted by residual exhaust gas, to thereby prevent generation of injurious components in the exhaust gases and improve fuel economy. During full load operation, when the fuel -air mixture is diluted to a lesser extent, the mixture is supplied to the auxiliary combustion chamber mainly via the main combustion chamber. The tube 25 passes through the exhaust manifold 29 for pre-heating the fuelair mixture. A suction valve 30 for the auxiliary combustion chamber, and the main suction valve 6 are operated by a common rocker arm 31. Alternatively, the auxiliary combustion chamber suction valve may be operated by the difference in pressures at the inlets to the main and auxiliary combustion chambers.

The overcharging of a cell 1 3  in a battery is prevented by arranging a microswitch 8 to be operated upon by the gas evolved by the cell during charging so that upon an excess pressure being developed the contacts 5 are closed to connect a resistor 4 in parallel with the cell so reducing the charging current through the cell. The resistor 4 may have a fixed resistance or may be composed of graphite discs to which the gas pressure may be applied so that, after having been connected in parallel with the cell, the resistance is variable. The pressure-responsive means comprises a body 19 which is attached to the cell, through which body is a passage 20 so that the gas pressure in the cell can operate on a flexible membrane 6 to move a member 26 so operating the microswitch by means of its plunger 7. A spring 24 is provided to return the member 26 to its normal position and an atmospheric vent 30 is provided to eliminate excess gas pressures in the cell.

Abstract: 1,132,995. Finishing yarns. SCHAPPE AG. 21 Dec., 1965 [22 Dec., 1964], No. 54010/65. Headings DID and D1F. A staple fibre yarn-of for example polyester fibres-is in one continuous process first twisted and then stretched, the yarn being heated to a temperature which causes thermal removal of fibre ends projecting from the yarn in both the twisting and stretching steps. As described a yarn is end unwound from a bobbin which is rotated to twist the yarn, passed through a heater, around a first pair of draw rolls one of which is driven, back through the heater, and around a second pair of draw rolls, one of which is driven at a faster peripheral speed than that of the driven roll in the first pair. The yarn passes around grooves in each draw roll. The heater which is electrically or steam heated, and may be temperature regulated, has an internal smooth yarn contacting surface which singes and heats the yarn and which may have two grooves, one for each passage of the yarn. The yarn may pass through more than one heater. There may be a series of stretch zones. The passage of the yarn over the grooves in the draw rolls also helps to smooth the yarn.

Abstract: 1357207 Pyridine from α-picoline STAMICARBON NV 26 Nov 1971 [4 Dec 1970] 55094/71 Heading C2C The invention comprises a process for the preparation of pyridine by gas-phase demethylation of α-picoline with steam at 250-360‹ C. in the presence of a metallic hydrogenation catalyst using a contact time of 0À5-15 seconds. Contact times are obtained by dividing the catalyst volume by the volume rate of flow per second of the gas mixture measured at any desired temperature and corrected to the reaction temperature and pressure. It is preferred to employ 4-25 moles of steam per mole of α- picoline in the reaction gas and a preferred catalyst is nickel on alumina or silica gel. Other catalyst metals specified are nickel, cobalt, platinum, palladium and ruthenium. Some 2,6-lutidine is produced during the reaction (#3%)# the amount may be increased by adding hydrogen to the reaction gas, preferably in an amount of 2-20 moles per mole of α-picoline. The gaseous reaction effluent is condensed and may then be extracted, e.g. with benzene and the resulting solution fractionally distilled.

C. engine, comprises a housing 11 having a fuel inlet 13 and a relief outlet 23 controlled by spring- loaded valve 15 whose setting can be varied by a manually operated lever 37 and axially moveable spool 27, a piston 71 acted upon on its upper surface 129 by fuel pressure, and on its lower surface 79 by fluid-pressure, controlled by a valve 105 disposed in a cam-shaft 101 and responsive to centrifugal force, and a spring 77, the piston having a groove 83 locating a pin 85 on a lever 87 which, via a shaft 89, controls the position of a spill port collar 93 on the plungers 95 of a fuel pump bonnet 97. Valve 105 has an annular recess 119, and as it moves outwards relative to the axis of the cam shaft 101, connects a port 117 with the underside of the piston 71 via passageways 121, 120 to balance the fuel-pressure acting on surface 129. When the speed decreases due to increased load, fluid-pressure in a bore 111 acts between the valve and a slug 113 to cause the valve to move inwardly to connect the underside of the piston with a relief outlet 137 via passageway 121, 134, and 135. Piston 71 is then moved downwards to rotate lever 87 and move collars 93 to increase the volume of fuel delivered, and the speed of the engine, until the fluid-pressure metered by valve 105 balances the fuel pressure acting on the top of piston 71. The downward movement of the piston 71 is limited by a resilient stop 141. Lever 39 is moved by a linkage (41), Fig. 2 (not shown), attached, e.g. to an accelerator, to adjust the setting of spring 25 between high and low speed positions (A) and (B) respectively. To stop the engine, the lever 39 is moved beyond position (B) whereupon it engages a notch (63) in a spring-loaded lever (47).

The part 42 has a spring biased valve 36 therein such that it is open below a predetermined rate of withdrawal of the rod and piston 31 and closed at and above said rate, when fluid can only pass through the clearance between the piston 31 and the cylinder 11, and on inward movement of the rod and piston 31 said valve permits fluid to pass relatively freely through the port. The valve may consist merely of a ball 40 with no spring. Alternatively, fluid transfer may be only through the clearance between the piston and cylinder, Fig. 7 (not shown). The embodiment of Fig. 3 shows the device in use with an air jack. Air is pumped into the portion 60 causing the cylinder 62 to rise thus causing the rod and piston 31 to rise.
