Abstract: 1,197,293. Thermal regenerators. J. R. DE FRIES. 28 June, 1967 [30 June, 1966], No. 29856/67. Heading F4K. In a thermal regenerator in which a fluidpermeable heat transfer mass moves continuously through gas streams at different temperatures such that each portion of the mass is contracted successively by the gases, the mass comprises a fine-mesh three-dimensional structure consisting of interconnected fibres the size and spacing of which is such as to permit a substantially unobstructed flow of the gases through the mass whilst at least some of the fibres act as microturbulence generators providing vortices in the flow and being positioned in relation to fibres upstream of them, in the disturbance caused by the micro-turbulence. The votices are small being generally limited to a size equivalent to twice the fibre diameter. The mass may consist of individual fibres bonded together at their points of contact; or it may consist of a polyurethane foam from which the cell membranes have been removed, e.g. as described in U.S. Specification 3,171,820. In an apparatus having a rotating mass and which is used, e.g. to transfer heat between discharged waste air and incoming fresh air, the mass may function as a fan and also as a course filter for the air streams. By spraying water into one of the air streams, evaporative cooling of the other stream is faciliated particularly when the cooling takes place in stages.

Title: Circuit arrangement for masking unwanted triggering pulses in the analysis of the ignition voltage curve of an internal combustion engine
IPC: F02P17/10
Filed: 1974-07-08
Abstract: 1473893 Monostable circuits SIEMENS AG 8 July 1974 [12 July 1973] 30254/74 Heading H3T [Also in Division G1] A monostable circuit K, Fig. 3, has its "on" duration set by a voltage fed back over its timing circuit R1, C1 in such a way that as its triggering rate rises its "on" duration falls. When the monostable K is "on", its terminal 1 goes low thereby cutting off a transistor T 1 and allowing a capacitor C2 to charge over R3, D1. When the monostable K is off, transistor T1 conducts and capacitor C2 discharge via R4, T1. The voltage on C2, which is thus dependent upon both the triggering rate and the "on" time, is fed back via a diode D3 to control the "on" time of the monostable K. A Zener D2, and a potential divider arrangement R5, R6, D4, C3, ensure that the voltage fed back to the monostable K cannot fall outside preset limits. The circuit is of particular use in analysing voltages derived from the spark plugs of I.C. engines, see Division G1, in which case the monostable is triggered by the leading edge a, Fig. 1, of the plug voltage to provide a blanking pulse lasting for substantially the remainder of the waveform.

Abstract: 344,808. Canning food &c. CONTINENTAL CAN CO., Inc., 100, East 42nd Street, New York, and TROYER, N., 601, Myrtle Street, Seattle, Washington, both in U.S.A. Oct. 7, 1929, No. 30323. [Class 49.] In a machine for vacuumizing and sealing cans, a pocketed valve moves the cans into and from the vacuum chamber and arms, 13, 18, mounted independently of the valve, remove the cans from the valve. The cans are fed along a conveyer 8, are spaced by an adjustable worm 9, and fed to a continuously rotated valve 4 within a vacuum chamber by a spider 10. They are removed from the valve and transferred to a rotary table 16 under the seaming heads by the spider arms 13, removed from the valve after seaming by a guide 17, extracted from the valve by a spider 18, and discharged by the conveyer 8. A guide 62 for the cans is pressed resiliently by a weight 68 on a bell crank. The spiders 13, 18 are operated independently of the valve and are splined to shafts 18a, Fig. 8 (not shown). The arms 168 of the spiders co-operate with the inside of the valve pockets to push the cans and are provided with pivoted grippers 170, closes against pressure of springs by cams for gripping the ends of and removing bent cans. The valve comprises castings bolted together to form a tapered pocketed body mounted to seal the vacuum chamber. The openings 165, Fig. 4, serve gradually to apply to the cans the vacuum and openings 164a, Fig. 9 (not shown), break the vacuum gradually. The valve is axially adjustable upon a driving shaft 70, carrying an arm which drives the valve through compression springs. The parts of the machine are driven by appropriate gearing from a belt pulley 86 on operation of a clutch lever 93 and rod 91. Means for seaming the cans within the vacuum chamber is described. Stop mechanism. To stop the machine when the valve is jammed, or when the vacuum drops, mechanism shown in Figs. 14 and 15 is used. The clutch rod 91 is operable by bell crank 188 cooperating with the piston of a vacuum cylinder 185. Energization of a solenoid 192 opens a valve 189 to operate the bell crank. A bent tube 227 within a casing 225 on the vacuum cylinder is connected to a pivoted tube 226 containing mercury and contacts wired as on Fig. 15. When the vacuum falls the tube is tilted and the contacts are closed by the mercury to energize the solenoid and stop the machine. Should the valve meet with abnormal resistance the springs are compressed, Figs. 11 and 13 (not shown), to operate a lever and rod for closing contacts 207, 208, Fig. 15, to thereby energize the solenoid 192. The valve and working surfaces are sealed with oil. The parts are lubricated by oil pumped from a sump to a chamber from which it flows by gravity through the mechanism back to the sump.
