Abstract: 1456927 Proof printing; tripping cylinders WINDMOLLER & HOLSCHER 24 Oct 1974 [24 Oct 1973] 46056/74 Heading B6C When it is required to stop printing in a web-fed multi-unit press, the impression cylinder of the first unit is tripped, the impression cylinder of the second unit is tripped only when the trailing end of the imprint from the first unit reaches the second unit, and subsequent impression cylinders are similarly tripped only as the trailing end of the imprint from all the previous units reaches the printing unit in question. On restarting the press, the web is pulled back until the leading end of the multiunit imprint on the web is at the first printing unit, the first impression cylinder is engaged with the web, subsequent impression cylinders being engaged in turn as the leading end reaches each unit. The invention is particularly applicable to proof-printing of a multi-colour transfer web; the press is stopped, a sample cut out from the web, and transferred, e.g. by heat or pressure to a textile; any resulting defects are then corrected by adjusting the press settings before recommencing printing. The invention is stated to reduce the amount of waste from the web when sampling.

Abstract: 1322582 Crystal-growing apparatus ARTHUR D LITTLE Inc 2 Oct 1970 [15 June 1970] 47059/70 Heading BIS  Apparatus for growing crystals, preferably by remote control, under high or low pressure conditions and capable of using the floating zone, Czochralski, and Bridgman-Stockbarger techniques is shown basically in Fig. 1. The apparatus consists of a furnace assembly 10. a power supply 11, and an operating console 12. The furnace 15 comprises a sealed port 16, a view port 17 associated with a TV camera 18 and support 19 whereby the conditions in the furnace are shown on screen 20 and controlled by an operator. The furnace assembly 10, is isolated from 11 and 12 by a barrier wall 13. Power for the crystal growing area is supplied by power inlet 25, carrying an r.f cable 28. Pressure is controlled in the furnace by gauge 30. For remote monitoring a second pressure gauge 29 is located on console 12. Communication between the interior of the furnace and a vacuum pump 32, is by way of a vacuum line 33 and a valve 34. The movement of the rods 36 and 37 are controlled by motion motors 38 and 39, a drive synchronizer motor (not shown) and a gear box 41. Temperature is controlled by thermocouples. Fig. 7, shows crystal formation using Czochralskis technique. The furnace comprises an upper section 90, a central section 91, and a lower section 92, which together define the working area 93. The crucible 101 containing the molten material 102 from which the crystal is pulled remains stationary while the crystal boule is pulled upwardly by head 94 affixed to rod 95. Aligned with upper rod 95 is a lower rod 96 which supports a graphite susceptor 97 as well as a support ring 98, affixed to the shaft through a support collar 99. Resting on ring 98 is an inner quartz radiation shield 100, and on support 111, an outer quartz radiation shield 110. The temperature is controlled by a thermocouple in the rod 96. A second temperature control is a sapphire light pipe 120 connected to a radiomatic pyrometer positioned on the outside of the furnace chamber. Heat is supplied to the crucible 101 by r.f coil 125. The apparatus can be modified to use the Bridgman-Stockbarger technique by moving rod 95 out of the way and mounting a suitably-designed crucible on rod 96. Crystallization is effected by rotating and moving rod 96 and its supporting crystal downwards. The apparatus is also easily adapted to a floating zone technique by attaching a cylinder of the material to be formed into a crystal between chucks attached to 95 and 96, and simultaneously moving the rods to rotate the rod and to cause it to pass through the heating area.

Title: Pour point determination and use for process control
IPC: G01N25/04
Filed: 1962-12-19
Abstract: 990,697. Testing utilizing mechanical waxes. ESSO RESEARCH & ENGINEERING CO. Dec. 19, 1962 [Dec. 26, 1961 (2)], No. 47961/62. Heading H4D. The pour point temperature of oil is determined from the reduction in the damping action of the oil on a vibrating element as the oil is cooled from a temperature above to a temperature below the pour point. The pour point temperature so determined may then be utilized to control the operating conditions of an oil processing system (e.g. a dewaxing operation) to produce oil having a required pour point temperature. The general arrangement for determination of the latter, which is described with reference to Fig. 1 (not shown), comprises means for deriving electrical signals respectively proportional to the vibration amplitude of the element and to the oil temperature together with timing and recording means for sequentially recording the two signals on a moving chart whereby the pour point temperature is indicated by a " break " in the vibration amplitude trace. The latter arrangement is included in the scheme shown in Fig. 2, for controlling the oil processing system to produce oil having a desired pour point temperature. As shown, the oil sample, which is contained in means 102 is, at the commencement of each measurement cycle, first heated due to the Peltier effect of thermoelectric elements 108 the polarity of the D.C. supply to which is then reversed by switch 131 so that progressive cooling results. For measuring the damping effect of the oil a paddle 112 carried by a probe 111 vibrated by an A.C. energized driving coil 113 is linked via a second probe to an output coil 114 in which a voltage proportional to the vibration of the paddle is induced and for measuring the oil temperature a thermocouple 109 is employed. The operation of the apparatus is controlled by a master timer 133 and a slave timer 134 in a sequence which includes the steps of (1) flushing the container 102 and filling with a fresh oil sample by operation of valves 105, 106; (2) energizing the vibrator driving coil 113 and operating switch 131 so that cooling of the oil results. At this stage the voltage induced in the output coil 114 operates the recorder pen 120 to produce a trace on moving chart 121 indicative of the vibration amplitude of the paddle 112 and when the pour point is reached the sudden reversal of the pen movement operates via a friction clutch 137 to close a switch 138 which is then effective via switch S 3  of the slave timer 134 to close the circuit between the amplifier 124 for the thermocouple output signals and the temperature recorder 128. The temperature of the break point is thus recorded and any difference between this and a predetermined temperature set by means 148 is utilized to control a valve 150 in the oil process control system. The latter system, as described with reference to Fig. 3 (not shown), may comprise means controlled by valve 150 for varying either the flow of oil or of solvent in a dewaxing arrangement.
