Title: Ellipsograph
Inventor: HILL KEITH AUDIS
IPC: B43L11/04
Filed: 1969-03-31
Abstract: 1,212,468. Ellipsographs. K. A. HILL. 31 March, 1969, No. 16763/69. Heading B6P. An ellipsograph comprises a main or first slide 18 mounted for movement on a base-plate (20, Fig. 1) between parallel guides 27, 29 in a first path. A cross or second slide 17 is mounted for movement on the first slide 18 by two parallel guiding edges 40, 41 in a second path at right angles to the first path. The second slide 17 carries a marking instrument 50 for movement therewith. A manually rotatable actuator comprising an adjustable crank mechanism in the form of a disc (61, Fig. 1), is mounted for rotation in a cover-plate (21) of the ellipsograph. A driving pin 73 is mounted for adjustment along a radius of the disc defined by a slot (76, Fig. 1). The driving pin 73 is connected to a proportioner 60 to move the latter and the slides 17 and 18 in response to rotation of the disc by a knob (71, Fig. 1). The proportioner comprises a diamond-shaped frame formed by pairs of long and short strips (79 and 80, Fig. 4) defining aligned front and rear corners (81 and 83) and aligned side corners (84), the included angle between the strips at the side corners being 90 degrees. Transfer of the component of motion of the drive pin 73 in the first path through the proportioner 60 and to the main slide 18 is effected by a set of guide members 85, 86 and (87, Fig. 4) mounted on the upper side of the main slide 18. Rollers 90 depending from the side corners (84) and roller 89 depending from the rear corner, respectively ride along the guide members 85, 86 and (87, Fig. 6). To transmit the crosswise motion (i.e. motion in the second path) of the driving pin 73 and the proportioner 60 to the cross slide 17, a lost motion correction including a pin 93 depending from the front corner (81, Fig. 6) is projected downwardly into a slot 94 formed in the cross slide 17. The major axis of the ellipse to be drawn is set by the radius at which the driving pin 73 is positioned relative to the driving disc axis. The minor axis of the ellipse is set by adjusting the angle of inclination of each guide member 85 and 86 on the first slide 18. The guide members 85 and 86 are pivotable about axes 110, and at their inboard ends have meshing gear segments (108, Fig. 6). The outer end of guide member 86 is provided with a cam follower (111) riding on a cam (113) rotated by an adjusting device mounted on the main slide 18 and extending up through a slot (118a) in the cover-plate (21, Fig. 1) of the ellipsograph. One extreme adjustment of the guide members 85 and 86 is when they extend in a straight line across the main slide 18, and cause the ellipsograph to describe a circle. The other extreme adjustment is the V-position taken up by the guide members when angularly displaced through approximately 35 degrees, which causes the ellipsograph to describe a straight line along the major axis.

Filed: 1927-06-28
Abstract: 286,142. White, A. E., (Roots Co., P. H. & F. M.). June 28, 1927. Movable-abutment type; packing abutments.- In a fluid handling apparatus such as a gas meter comprising lobed impellers 15, 16 rotating in a housing 10 formed with a gas inlet 11 and a gas outlet 12, leakage of gas past the impellers and the deposit of tar and other impurities on the impellers are prevented by supplying a sealing and flushing liquid such as oil to the housing. The liquid is fed to the impellers from a tank 25 through sight-feed devices 31 and spaced distribution pipes 26 - - 30 entering the gas inlet 11. After passing through the housing the liquid is diverted by drip plates 40 into a sump 37 formed in the bed plate 35 and is then returned to the tank 25 by a pump 45. An overflow pipe 50 connecting the tank 25 to the sump 37 prevents the liquid level in the tank 25 from becoming excessive. A tank 60 fitted with a filling plug 62 and connected by pipes fitted with shut-off valves 61 to the pipe 50 allows the liquid in the system to be replenished during the operation of the apparatus. The outlet main may be fitted with a. trap 100, Fig. 5, provided with a baffle 104 in front of the gas outlet 101 and having a connection 46 to the pump 45.

Title: Improvements relating to Optical Scanning Devices.
IPC: H04N3/09
Filed: 1967-04-14
Abstract: 1,153,384. Optical scanning apparatus. OPTISCHE INDUSTRIE " DE OUDE DELEFT " NV. 14 April, 1967 [19 April, 1966], No. 17234/67. Heading H4F. The invention relates to optical line-scanning apparatus for use with a photo-electric detector. In one embodiment, Fig. 1, the scanning device comprises a rotating shaft 1 carrying plane mirrors 2, 3. Light from a point on the object being scanned and forming partial beam A is reflected by mirror 3 to an objective mirror 5 which focuses the beam on to a detector 6. Light from an adjacent point on the object and forming partial beam B is reflected by triple reflector 4 on to mirror 2, also directing this beam to objective 5. The arrangement is suitable for scanning a line or narrow strip across the object which is perpendicular to the axis of the shaft or, if the object is moving relative to the scanning mechanism in a direction perpendicular to the scanning direction, adjacent lines or strips. In a second embodiment, Fig. 4 (not shown), the triple reflector is replaced by a concave mirror (8) which is arranged to receive the partial beam (B) through a lens or lens system (7) which forms a part of the shaft. The lens focuses light from the object at or near the focal point of the mirror which reflects the beam on to the scanning mirror (2) facing away from the incident beam. The mirror provides a scanning angle of 120 degrees whereas the triple reflector provides only 90 degrees. The mirror (8) can be located so as to receive beam (B) through a lens mounted on the left (as illustrated in Fig. 4) or the right of the mirror combination 2, 3. The lens (7) may be aspherical to connect for the spherical aberration of the concave mirror (8). Two pairs of scanning mirrors may be provided. The scanning apparatus can be used in a thermographic system (production of a visual radiation " map " of the surface of an object by detection of the emitted infra-red radiation), the use of the fixed reflector being to avoid collection of stray radiation by the scanning mirror(s) not directly in the path of radiation from the object.

IPC: C10B47/00
Filed: 1921-06-24
Abstract: 168,859. Meguin Akt.-Ges. Butzbach, and M³ller, W. Sept. 4, 1920, [Convention date]. Retorts.-Coal and the like in small pieces or in a ground condition is carbonized at low temperature with production of a semi-coke in a rotary apparatus in which the coal is charged from a hopper d and distributed by a feed-screw c rotating inside a perforated fixed casing, over the whole length of a rotating drum a externally heated by burners l. A discharge casing e is provided with a pipe g for the distillation gases and with an outlet f for the coke. During the carbonizing period, the drum is rotated at such a speed that centrifugal force tends to hold the material against the entire periphery of the drum and by exerting pressure to cause the semi-coke to acquire solidity. The speed of rotation is reduced when the drum is emptied, and continuous working may be attained by inclining the drum or making it of conical shape as shown by the dotted lines. The shaft of the conveyer c may be employed for the supply of steam, and the drum may be provided internally with baffles. The drum may also be arranged vertically with a spreader to bring the coal into contact with the side of the drum.
