Title: Improvements in or relating to a device for jogging the printed sheets on the delivery table of sheet printing machines
IPC: B65H31/38
Filed: 1951-05-25
Abstract: 698,002. Sheet delivery a p p a r a t u s. MASCHINENFABRIK AUGSBURG - NURNBERG AKT.-GES. May 25, 1951 [May 25, 1950], No. 12367/51. Class 100(i) In a device 15, 28 for jogging the printed sheets on the delivery table of sheet printing machines, the rear jogger 28 is reciprocated through toothed racks 25 by means of gear wheels 19 releasably connected to a driving shaft 18 which is part rotated in opposite directions alternately. Release of the wheels from the shaft (e.g. by unscrewing from the shaft a nut 21, which otherwise clamps two gear wheels 19, a spacing tube 20 and a bushing 24 between itself and a bushing 24a) enables the position of the racks 25 and the jogger 28 relative to the shaft to be changed to accommodate any sheet size. By means of coupling members 29, a hand wheel 23 on the bushing 24 is used to turn the wheels 19 and so adjust the position of the jogger and its racks which travel in guides 26 in the machine frame. The device is driven by a gear wheel 2, Fig. 2 on the shaft of end wheels of a delivery chain, which wheel drives with speed reduction a gear wheel 3 with an eccentric bushing 4. A lever 6, mounted by a roller bearing 5 on the bushing 4, is thus reciprocated together with a connecting rod 16 which oscillates a lever 17 secured to the shaft 18. Lateral joggers 15 are mounted on adjustable rods 13 each of which is clamped at 14 in a slotted portion of a sleeve 12 having teeth meshing with a gear segment on one arm 11 of a bell-crank lever 10, 11 pivoted on a fixed shaft 9. By means of a ball joint 8, a rod 7 transmits the reciprocation of the oscillating lever 6 to the bellcrank lever and thus to the jogger 15.

Title: Microtome
IPC: G01N1/06
Filed: 1968-03-14
Abstract: 1,181,945. Microtones. MILES LABORATORIES Inc. March 14, 1968 [July 17, 1967], No.12548/68. Heading G2J. A microtone comprises a holder 30 carrying a specimen 34, a co-operable blade 22 mounted in a member 14 for movement towards and away from the holder 30 and a spring 62 which biases the blade 22 towards the specimen and also holds a bearing 54, on member 14, against a surface 40 of an adjustable cam 38, and a surface 42 of the latter against a surface 60 rigid with the holder 30, the position of cam 38 determining the thickness of the slice. As shown the holder 30 and surface 60 are provided on a shaft 28 so that when the latter is rotated, either manually, or by means of a motor driven shaft 88, the specimen 34 is rotated into contact with the blade 22 and a gear train 68, 70, 72 is set in motion. Gear 72 is rigid with a five-toothed gear 61 which is so arranged that it engages a gear 73 only after the specimen 34 has passed the cutting edge 23 of blade 22. The rotation of gear 73 causes a pawl carrier 76 to rotate against the action of a spring 77 carrying with it a ratchet wheel 79, which, through helical gears 78, 80 and screw 58 causes the cam 38 to slide to the left. The consequent movement of member 14 about its pivot 16 moves the blade 22 downwardly ready to cut specimen 34 again during the next rotation of shaft 28. When the five-toothed gear 61 has disengaged gear 73, the pawl carrier 76 returns to its initial position under the action of spring 77. The pawl on pawl carrier 76 may engage ratchet wheel 79 for a portion only of its total travel by varying the angular position of an opening 87 in a protruding portion 85 of an adjustment sleeve, so as to vary the amount of movement of cam 38 and thus the thickness of the slice. By positioning a microscope slide on guides 44 against an abutment 91, a finger 96 on a chain 92, driven by a gear chain from shaft 28, carries the slide over the blade to receive a slice thereon.

Patent GB-112952-A (GB)
Title: Improvements in or relating to Internal Combustion Engines.
Inventor: WATKINSON WILLIAM HENRY
IPC: F01L13/08
Filed: 1916-09-07
Abstract: 112,952. Watkinson, W. H. Sept. 7, 1916. Regulating. - In engines in which air is compressed to the ignition point before the injection of the fuel, the ignition temperature is obtained with a low compression by wire-drawing the charge, the pressure of which at the commencement of the compression is thus less than, and the temperature substantially the same as, that of the atmosphere. When wiredrawing the air charges at starting only, fuel may be admitted in excess during the major portion of the expansion stroke. According to the arrangement shown in Fig. 1, air is drawn through a silencer a past a wire-drawing valve b which opens into a chamber b<1> leading to the cylinder (not shown). The tension of the valve spring c is regulated by a hand-wheel e which also controls, through an arm r<5>, the time of closing of the suction valve s of a fuel-supply pump. A modified means for controlling the fuel supply is described in which the link r is secured to a fluid-actuated piston working in a cylinder in which the pressure is the same as that existing in the chamber b<1>. The wire-drawing valve, which may be of the butterfly type, may be connected to an automatic speed-governor. When this arrangement is used at starting, it is combined with a valve of the type shown in Fig. 1. Fig. 4 shows a modified construction applicable to aircraft, the wire-drawing valve b being controlled by flexible corrugated members containing air at or above atmospheric pressure and located in a casing k open to the atmosphere. An increase in the altitude reduces the wire-drawing, which may be further controlled by the hand-wheel e. The normal cam-actuated air-admission valve may be used to wire-draw the charge at starting, the camgear being put out of action, wholly or in part, and the suction in the cylinder utilized to open the valve automatically. When starting engines using a hot bulb or a vaporizer, the cylinder clearance space is reduced before wire-drawing the charge, the wire-drawing valve and a piston for reducing the clearance being adjusted simultaneously. In multi-cylinder engines of this type, the method of starting by wire-drawing the charge and reducing the clearance may be applied to one charge cylinder only, the products of combustion from this cylinder being admitted to the other cylinders for heating purposes. Alternatively, air heated by the combustion gases, and wire-drawn, if desired, may be admitted to these cylinders. To vary the clearance, the cylinder may be adjusted relatively to the crank shaft. A modified method of working is described in which the air, before being admitted to the cylinder, is expanded in a supplementary motor to a pressure below that of the atmosphere. A heating coil through which the air passes is located between the two motors. According to a further method of working, compressed air is admitted to the cylinder after ignition of a wire-drawn charge, the supply being regulated by a governor or by hand.
