A printing surface suitable for use with powdered printing material comprises a porous body 10, Fig. 2, which has a plurality of openings 12 therein, the said openings being smaller than the particles of the powder which may be in the dry state or in the form of a slurry, and a mask 14 provided with cut-out portions 16 which provide a pattern for the desired image. The porous material may be sintered bronze particles, fibrous steel or ceramic, fibrous or plastics material treated to make it conductive. The mask may be produced by cutting out paper tape, photographically treating a gelatine emulsion, or printing on the body 10 with a liquid which hardens. Intaglio printing.-In the embodiment of Fig. 3 a mask 32 is located on a porous conductive cylinder 20 partially immersed in a container 34 containing electroscopic powder particles. Suction is applied to the interior of the cylinder 20 except for the segment defined by walls 28, 30 at the image transfer position by a suction source 24 and air under pressure is supplied through apertures in the base of the container 34 so that the particles form a cloud and as the cylinder rotates they are drawn against the exposed portions of the cylinder. A doctor blade 36 removes excess powder and the powder image is transferred to the web 38 when the suction is removed from the portion of the cylinder between the walls 28, 30, by applying positive air pressure within said walls, or with the help of an electric field established between the cylinder 20 and a plate 44 with the aid of a roller electrode 48. Fig. 11 (not shown) depicts an embodiment in which an intaglio cylinder co-operates with a porous impression roller, the interior of which is connected to a source of suction to draw the powder impression on to a porous web. Fig. 7 shows an arrangement in which a plurality of planar intaglio printing surfaces 110-120 are supported on housings 122-132 carried by a chain 138, suction being applied when the surfaces are over a powder container 136 and at every station except the image transfer station at which the powder images are transferred to a container such as 104 on a conveyer 108. Stencilling apparatus.-The mask may be movable independently of the porous cylinder either in web form, Fig. 5 (not shown), or in the form of an endless belt, Fig. 9 (not shown), and Fig. 10. In Fig. 10 a multi-colour image is applied to the cylinder through three endless stencil bands supported by rollers. The image transfer to the web 194 may be aided when the suction to the interior of the cylinder is removed by an electric field.

Title: Improvements in and relating to electric control systems for well drilling plant
IPC: E21B19/08
Filed: 1933-05-18
Abstract: 419,609. Winches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Weaver, C. E. ; 1069, Waverly Place, Schenectady, New York, U.S.A.) May 18, 1933, No. 14434. Convention date, May 18, 1932. [Class 78 (v).] Control means for a welldrilling apparatus comprises a diaphragm separating two pressure chambers and connected to a switch in one of the chambers, and means responsive to the load on the drillsupporting cable to produce a pressure in one of the chambers acting against a desired pressure built up in the other chamber, difference in pressure on the two sides of the diaphragm causing actuation of the switch and energization of a motor controlling the drill cable so as to vary the weight on the drill. The drill is supported by a cable 12, one end of which is wound on a drum 13 normally held by a catch 15 and adapted to be driven by a motor 14 which may also drive the rotary table 69 ; the other end is wound on a drum 16 adapted to be driven by motor 18 through gear box 19, worm gearing 20, 21 and chain 22, an electric brake 65 being provided for the motor shaft. End thrust of the worm 20 due to the tension in the cable acts through a diaphragm in a container 25 to compress glycerine &c. which acts in chamber 271 against one side of a reinforced diaphragm 26, a gauge 28 indicating the pressure. Air pressure is built up in a casing 32 by means of a pump 30 with pressure gauge 60 and acts on the other side of diaphragm 26. A bolt 42, secured to diaphragm 26, carries opposed springs acting on a member 41 carried by lever 40 connected by link 38 to a switch armature 39 between contacts 33f and 33, a spring 48 biassing the armature 39 towards contact 33f. Through valve 61, the air pressure in casing 32 is adjusted to give a desired pressure difference on the sides of the diaphragm 26, according to the drill pressure desired. Excessive load on the cable 12 then causes diaphragm 26 to move armature 39 against contact 33f and through relay 55, close switch 57 and thereby release brake 65 and energize motor 18 to cause paying out of cable 12. If the drill is obstructed as by formation of a clay ball, the flushing fluid acting below the latter reduces the tension in the cable 12 and therefore the hydraulic pressure in chamber 27<1> and the air pressure moves the diaphragm to bring armature 39 against upper contact 33r and through relay 56 and switch 58, release brake 65 and energize the motor in the reverse direction to effect winding in of the cable 12. When winding in, as to release a stuck drill, the air pressure in chamber 32 may be built up to correspond to the maximum safe load for the derrick, whereby when this load is exceeded, the motor 18 is energized to rotate drum 16 to pay out the cable 12.
