摘要： 310,321. Gray, R. L., (Assignee of Allwill, S. S.). April 28, 1928, [Convention date]. Four-stroke-cycle engines; cylinders, varying clearance of.-A cylinder head, in the form of a sliding piston, is automatically adjusted so that a maximum compression pressure in the cylinder is never exceeded. The sliding piston 11 is adjusted by an annular screw-threaded member 15 which is rotated through a rack 64 and pinion 52 and a worm 51 by the difference of pressures acting on pistons 56, 57 carried by the rack rod 53; the piston 56 is subjected fluid pressure acting through a pipe 59 or the pressure of a spring 55 having an adjustable abutment 98; the piston 57 is subjected to the cylinder compression pressure acting through passages 60, 72 when. a valve 61 is opened by the engine, and when this pressure execeeds the pressure acting on the piston 56, the pistons 56, 57 move and the piston 11 is lifted. At ignition the valve 61 closes the connections 60; later it opens a. connection 73 leading to the induction pipe when the pistons 56, 57 fall. A connection to a speed governor 83 reduces the degree of opening of the valve 61 as the speed increases. Separate control pistons may be provided for each cylinder of a multicylinder engine, and in the over-head valve engine shown the cam-shaft 27 is divided into separate sections for each cylinder, the sections being connected by flexible couplings, and driven by a vertical shaft having a telescopic joint. If one pair of control pistons 56, 57 only is provided for the engine the connection 73 is omitted and the piston 11 does not then move during the cycle. The application to side valve and sleeve valve engines is also described, and in these cases the cylinder head is rotated on a fixed screwthread to adjust the clearance.

摘要： The display device illustrates the ability to maintain a load without the support of compressed air. The display device comprises an expandable base (24) in contact with the floor, a support (32) connected to the expandable base wherein a distal end (30) of the support is substantially, vertically above the base, and a display (17) attached to the distal end of the support wherein the display comprises a plurality of tire sections (12, 14) and each tire section has compression means (16, 18) associated therewith for compressing the tire section.

摘要： An apparatus and method for cleanly breaking a continuously advancing cellulose web includes a transfer fabric which supports and advances the cellulose web to a wind up zone. The transfer fabric forms a closed loop and is driven at a desired speed by a drive roll. At least two spray nozzles are arranged transversely across the advancing cellulose web as it is carried on the transfer fabric. The spray nozzles are capable of emitting a liquid under high pressure against the advancing cellulose web to form perforations across the width thereof. A plurality of hollow cores are independently and sequentially moved into position at the wind up zone to receive the advancing cellulose web. The hollow cores are located downstream of the spray nozzles and each hollow core is capable of accumulating a predetermined amount of the cellulose web. The apparatus further includes controls for activating the spray nozzles in timed sequence to the speed of the transfer fabric such that a predetermined amount of cellulose web can be accumulated on each hollow core to form a finished roll having a predetermined diameter. An assembly is also present for moving each of the finished rolls away from the advancing cellulose web while simultaneously moving a second hollow core into contact with the advancing cellulose web upstream of the finished roll. The contact by the second hollow core and the employment of vacuum increases the tension on the advancing cellulose web and causes the advancing cellulose web to cleanly break at the perforations and form a leading edge. A vacuum is then applied to the second hollow core which causes the leading edge of the advancing cellulose web to wrap onto it. The method encompasses the sequential steps required to break the advancing cellulose web using the above-identified apparatus.
