Title: Improvements in or relating to the scavenging of the cylinders of two-stroke internal combustion engines
IPC: F02B25/00
Filed: 1938-01-06
Abstract: 494,869. Cylinders. PETTERS, Ltd., and BROOKS, H. Jan. 6, 1938, No. 449. [Class 7 (ii)] In a two-stroke engine cylinder, which is exhausted from the cylinder head, scavenging air is admitted through piston-controlled ports which are arranged so that in addition to general turbulence, the charge as a whole rotates about the cylinder axis. The Figure shows a cross-section transverse to the cylinder axis through the ports E; the majority of which are tangential to the cylinder in an anticlockwise sense, but some are radial, or tangential in the opposite sense. The ports may all be radial, the directioning being effected by slots in a circumferential part of the piston crown, which need not extend to the full height of the ports.

A pair of cables 25 from the secondary of a transformer 22 are connected to terminals 27 of which the centre terminal is connected to the base and the outer terminals are insulated therefrom. The member 1 is drilled and slotted to receive a carbon rod, or a pair of metal holders 33 for a carbon rod 32 for line soldering or a holder for carbons 40 and a steel bit 38 carried thereby. In these cases the centre and one of the outside terminals are used the latter being connected to the member 1 by a cable 28. The rods 8, 14 are adjusted in length and the position of the collar 2 adjusted so that when the treadle is opened the tool comes into contact with the work and so that on further pressure thereon a switch 24 in the primary of the transformer is closed. The work is held by clamps secured in grooves 31 in the base plate. The member 1 may be replaced by a soldering iron as described in Specification 546,696, [Group XI], including a pair of metal rods 35, 36 insulated from each other, the rod 35 carrying a carbon heater 34 fitting into a metal holder in the rod carrying a bit.

Abstract: PURPOSE:To detect the residual amount of an unphotographed sheet film with high accuracy, by providing a discriminating/displaying part where the residual amount of the sheet film is discriminated and displayed with reception of a signal from a pair of photodetectors. CONSTITUTION:The following working is carried out when the residual amount of a stored unphotographed sheet film 12 shows 10 sheets after repeating the shooting. A film sucking cylinder 16 lowers down to an arrow mark X, and a sucking rubber cup 18 is pressed to the film 12 as conventional. The optical paths 15 and 15' formed to a film storing magazine 13 are set opposite to optical fibers 19 and 19' provided to the cylinder 16 when the cylinder 16 is at the lowest position. Thus the light of a light emitter 20 that transmits the fibers 19 and 19' reaches photodetectors 14 and 14'. Then the detection signals of the detectors 14 and 14' are delivered via output lines 21 and 21' and supplied to a discriminating circuit 22 consisting of an AND circuit to be delivered to a display circuit 23 of the next stage.

Filed: 1998-01-05
Abstract: PROBLEM TO BE SOLVED: To accelerate a practical signal transmission speed by transmitting the one of slower transmission at the node between the rise and fall of signals to a poststage in advance. SOLUTION: A multiplexer 3 which is a signal advance transmission circuit transmits the rise of the output signals of a logic gate G to the poststage in advance. The multiplexer 3 selects the signals from input 0 in the case that the signal of the input S is 0, selects the signals from the input 1 in the case that the signal of the input S is 1 and outputs the selected signals from output U to the poststage. In the initial stage of a synchronizing operation, the signal of the input S from a path PS is turned to 1 and the multiplexer 3 selects the power supply voltage VDD of the input 1 and transmits the rise to the poststage in advance.  The output of the multiplexer 3 is kept at 1 when the output of the logic gate G is established as 1 and then the signal of the input S becomes 0 after a prescribed time from the initial stage and the output of the multiplexer 3 is changed to 0 when the output of the logic gate G is established as 0 and the signal of the input S becomes 0 after the initial stage.
