Patent GB-1241581-A (GB)
Title: Lithographic press
Inventor: KANTOR PAUL RALPH
IPC: B41F33/10
Filed: 1968-08-07
Abstract: 1,241,581. Printing apparatus. P. R. KANTOR. 7 Aug., 1968, No. 37739/68. Heading B6C. [Also in Division G3] In an offset lithography or photo-offset lithography printing press the supply of dampening solution D from fountain 40 to printing plate 3 is regulated retroactively in accordance with electrical measurements of the amount of solution being transferred at a point in the dampening apparatus 17 between fountain roller 42 and plate 3. Roller 24 is non-conductive and roller 36 is metallic. A measure of the amount of dampening solution on roller 24 is obtained by measuring the electrical resistance between detector roller 50 and roller 36, which is indicative of the thickness of dampening solution layer S. This measurement is used to actuate apparatus which energizes solenoid 145, so holding messenger roller 46 out of contact with fountain roller 42, unless an increase in the measured resistance indicates that further dampening solution is required. Suitable dampening solutions contain water, optionally alcohol, gum arabic and ammonium bichromate, the amount of ammonium bichromate being varied to give the solution a resistance suitable to the particular case. Detector roller 50 may be mounted on a solution-storage roller which rotates in contact with roller 36 only, so acting as a reservoir, or may constantly contact messenger roller 46, moving with it. Messenger roller 46 may be metallic, in which case a direct measurement of the dampening solution between it and roller 36 is obtained. Roller 24 and the storage roller, if one is present, may have rubber cores and cloth covers, or may be of rubber. Ink is separately supplied to printing plate 3, which may be of metal or paper, at a constant rate, so control of the supply of dampening solution controls the ink to dampening solution ratio in printing.

Title: Improvements in coke oven batteries
IPC: E21B19/07
Filed: 1962-10-05
Abstract: 956,538. Bracings for coke ovens. ALLIED CHEMICAL CORPORATION. Oct. 5, 1962 [Dec. 6, 1961], No. 37840/62. Heading F4B. To prevent damage to the brickwork of a coke oven battery having alternate coking chambers and heating walls during cooling or heating periods, cooled tension members are passed through the coking chambers to apply compressive forces to the buckstays at each end of each heating wall. The tension members 23, within water jackets 47, pass through the coke oven doors 21, 22 below the refractory plug or through a hole in the plug which can be closed during operation of the oven. Two pairs of beams 27, 35 extend along the sides of the battery engaging the buckstays 17, 18 through packing pieces 28, 36, and rails 29, 37 carrying apertured plates 31, 38 are secured to the beams 27, 35. A single pair of beams 27, 35 may extend the full length of the battery, or a number of shorter beams, each engaging at least two buckstays may be used. The tension rods 23 pass through the plates 31, 38 and at the coke side, the ends of the rods 23 are fixed by wedges 32 and clamps 34. At the pusher side end of each rod 23 an hydraulic jack 43 and a pulling head 41 secured to its end are used to apply the necessary tension to the rod 23, which is secured by a clamping wedge 44 seated in plate 45 by the action of the jack 43. In a large battery, the action of the buckstay top and bottom anchors 90, 93 may be supplemented by tendons 58 above the coke oven roof 16, and, in an underjet oven, beneath the oven soles 11. Yokes 99, 113, Fig. 8, with their ends connected to beams 96, 97 fastened through spacers to the buckstays 17, 18 are joined by tendons 98, 112 to a frame 106 where the length of one tendon is adjusted by an hydraulic jack 104. Instead of a single tendon for each pair of buckstays, separate tendons on either side of the backstays may be adjusted individually. Since the silica bricks of a coke oven do not expand or contract appreciably above 1800 F., during the cooling of a battery, the tensioning members are not placed in position until this temperature has been reached after about two weeks. During the further cooling of the battery at a controlled rate, the tensions on the members are adjusted periodically, and the tension is released at intervals to allow the brickwork to settle under gravity.

Abstract: 1388588 Counting broken threads NORDISKA MASKINFILT AB 23 Aug 1972 [23 Aug 1971] 39344/72 Heading G4D [Also in Division G1] In an apparatus for detecting broken warp threads in a weaving machine a laser light beam 9 is made to rotate (see arrows 16 in Fig. 2), by a rotating hollow shaft 12 and optical element 13 the beam being received by a photoelectric cell 10 with a collecting input screen. Alternatively the beam can be made to reciprocate. As can be seen from Fig. 2, the light beam should, under normal conditions, intercept the warp threads 2 four times each rotation, thus the output pulses of the photo-cell above a predetermined level are counted for a predetermined number of revolutions and then compared with a predetermined number and if it is exceeded, indicating a thread hanging down &c., a signal is generated (Fig. 3, not shown), which stops the weaving machine and/or operates an alarm. So that any loose lower warp threads can still be scanned by the beam a catching device 15 is provided for the loose threads to lie on and thus be detected. Disturbances occurring within different portions of the area of movement of the light beam may be detected by employing several clocks which connect and disconnect individual counters for registration of the situation in the corresponding portion in synchronism with the beam.
