Title: Improvement in automatic paper punching machine
IPC: B26F1/12
Filed: 1948-09-01
Abstract: 646,980. Endless conveyers. BURN & CO., Ltd., J. Sept. 1, 1948, No. 23044. Convention date, April 14. [Class 78 (i)] [Also in Groups II and VIII] A continuously-running conveyer receives " lifts " or packets of sheets of paper from a stack of sheets and conveys them to a point opposite a punching device of a machine where intermittently-operated holding means holds the lifts against further movement by the conveyer and the lifts are moved laterally with respect to the conveyer into the punches, always remaining in contact with the conveyer so that when the punching operation has been effected the conveyer delivers the lifts straight out of the machine. As shown, conveyer tapes 84, 85 run respectively over pairs of rollers 86, 87 and 90, 91 and carry the lifts fed from a magazine by a pusher device (see Group II) up to a stop 114 pushed up intermittently between the conveyer tapes by a rocker mechanism operated by levers 118, 119 from a cam surface 122 in synchronism with the pusher mechanism of the lift feed device. As the lift reaches the stop 114 a jogger 124 comes up from behind it and squares up the lift against the stop 114. A pusher feeds the lifts laterally under the punches (see Group VIII) and the stop 114 is lowered practically as soon as the punch takes hold of a lift. The jogger under the influence of spring 129 remains in contact with the lift during the punching operation and serves to initiate movement of the punched lift out of the machine by the conveyer tapes 84, 85 when the punches are withdrawn. The pairs of rollers 86, 87, or 90, 91 are carried in upper and lower frames, the shaft 88 of roll 86 being supported in sliding journal boxes 96 downwardly urged by adjustable springs 99. The upper frame 94 and the shaft 88 can be turned into a raised position in which the conveyer 84 is completely separated from the conveyer 85, by means of an inclined hook-shaped cam 97 engaging over rolls 98 on the journal boxes of shafts 88. Specifications 447,231, [Group XV], and 452,897, [Group VIII], are referred to.

Abstract: 865,097. Endless conveyers on vehicles for handling materials. CONCRETE CARRYING CO. Ltd. June 24, 1959 [July 18, 1958], No. 23082/59. Classes 78 (1) and 78 (4). A conveyer 3 (Fig. 1) for receiving material from a conveyer 2 at the bottom of a vehicle body can be stowed beneath the conveyer 2. In the form shown the inner end of the conveyer 3 is supported by pins 26 from slots in a yoke 24 mounted for movement about a vertical axis on a bracket 29 hinged at 30 (Fig. 5) to the vehicle so that when it is raised it guides the pins 26 into engagement with channels 35 on the vehicle. Upward movement of the bracket 29 is resisted by springs 33. The outer end of the conveyer is supported by a yoke 4 which is suspended from a jib 7 telescoped and locked hydraulically, and which carries rollers 5 engaging tracks 6 on the frame of the conveyer 3. Movement of the conveyer 3 about its slewing axis 27 (Fig. 5) is restrained frictionally under the influence of springs 28, and the pins 26 are formed so that they can escape from the slots 25 in the yoke 24 only when the conveyer is horizontal. Recesses 37 inside plates 31 supporting the tracks 35 engage rods 36 on the yoke 24 to centre it as the bracket 29 is swung upwardly. The conveyer 3 is driven by an hydraulic motor adjacent its inboard end.

Title: Apparatus for pneumatically monitoring conditions of a well circulating system
IPC: E21B21/08
Filed: 1976-06-04
Abstract: 1537317 Boring earth &c WARREN AUTOMATIC TOOL CO 4 June 1976 [6 June 1975] 23312/76 Heading E1F Apparatus for use during drilling operations to monitor conditions of the mud circulating system includes means for generating a first pneumatic signal representative of the rate of movement of the mud pump and first display means for the first signal; means for generating in response to the first signal a second pneumatic signal representing the predicted pump output pressure and means for displaying this signal together with the actual pump output pressure; and means for generating in response to the first signal a third pneumatic signal representing the predicted mud flow rate out of the well and means for displaying this signal together with the actual mud flow rate out of the well. As described the mud pump 10 shifts a valve 14 on each stroke to produce a series of on-off pneumatic pressure pulses in line 18. A repeater circuit 20 converts this signal to a pair of complementary signals in lines 36, 38 which in turn are converted by divider circuit 40 into a pair of complementary signals in lines 48, 50, these signals having equal on-off duration and having half the frequency of the original signals. These signals are fed to three metering circuits 56, 58, 60 which convert the pulses into analog pneumatic pressure signals which are displayed on gauges 116, 118, 120. The circuits 56, 58, 60 are designed such that gauge 116 indicates the pump speed, gauge 118 indicates the predicted mud flow out of the well and gauge 120 indicates the predicted pump output pressure. Gauges 118, 120 are duplex gauges, gauge 118 including a second pointer 130 which indicates the actual mud flow out of the well and gauge 120 also indicating the actual pump output pressure. The apparatus can be used to detect conditions such as pump malfunction, lost' circulation and breaks or fluid leakage in the drill string.

Title: Method and apparatus for isoelectric focusing
IPC: G01N27/447
Filed: 1973-05-16
Abstract: 1437377 Isoelectric focusing LKB-PRODUKTER AB 16 May 1973 [16 May 1972] 23426/73 Heading C7B  Components (e.g. proteins) in a sample solution having a density gradient are separated by isoelectric focusing in at least one focusing chamber. The sample solution is subject to a direct current electric field parallel to the density gradient, the focusing being carried out in at least two focusing steps with the mean cross-section of the focusing chamber perpendicular to the electric field in each step being smaller than in the nearest preceding step. Isoelectric focusing is an electro-phoretic method of separation, based on differences in isoelectric points of the sample components and is performed in an electric current path having a varying pH. After equilibrium has been achieved, each separated substance is at the point in the pH gradient which corresponds to its isoelectric point. The pH gradient can be obtained either by mixing solutions of varying pH in gradually varying proportions, or can be obtained by the influence of the electric field on a number of ampholyte substances having different isoelectric points. Fig. 1 shows two sections of a focusing column 14 having a cooling jacket 1, 2. The first and second focusing steps are performed with the column respectively horizontal and vertical. In the first step there is, as shown, a Hg electrode 7 at the bottom and a removable Pd-Ag electrode 12 at the top. For the second step, the electrode 12 is removed, the column carefully turned upright (the mercury electrode thus moving to the bottom of the column), a Pt wire electrode is inserted at 6 into the top of the column and the second focusing step performed. The separated fractions can be emptied from the column or, if the column is of quartz, can be subjected to U.V.-absorption analysis. Fig. 2 shows alternative apparatus comprising a prefocusing column 21 and final focusing column 25 provided with a cooling jacket. Electrodes 27 are separated from the column 21 by glass filter discs 24 and the anolyte and catholyte 22, 23 are circulated through cooled tubes by pumps 29. For the prefocusing, the device is turned 90 degrees around an axis perpendicular to the plane of the paper so that the column 25 has a horizontal axis but for final focusing is turned to the position shown. Sample solution, after prefocusing, is transferred from column 23 to 25 by suction, with the removed solution being replaced by a solution of a greater density supplied through the opening 30. Materials are specified for the electrodes. In a further alternative, the different focusing steps are carried out in a focusing chamber defined by an elastic material and in which, after each focusing step, the chamber is elongated in the direction of the electrical field with a simultaneous reduction in the mean cross-section perpendicular to the field.

Filed: 1945-09-14
Abstract: 607,701. Making piston &c. rings. BRAMBERRY, H. M. Sept. 14, 1945, No. 23704. [Class 83 (ii)] [Also in Group II] In a method of manufacturing a piston ring or other annular article having a small cross-sectional dimension from a nitridable alloy steelsuch as Nitralloy " N " or " G "- which grows on intriding, a blank of the same shape but of smaller diameter than the final article is confined in a furnace fixture having a contour corresponding to that of the final article and subjected to a nitriding atmosphere for a selected time and at a selected temperature-below the critical temperature of the alloythe growth of the blank being employed to exert pressure against the fixture to prevent distortion of the article, and the blank finally removed from the fixture. The method is described in connection with piston rings, a cylinder liner and a gear. In the case of piston rings, blanks PR, Figs. 9 and 10, having notches N in the portion JSR to be ultimately removed, are loaded on to a male former 12 having the shape of the final split ring in its free condition (and referred to as " parabolic-like") and brought into continuous contact therewith by a pressure tool 14, Fig. 8, the cap 23, spring washer 18, bolt and nut 25, 26 holding them in position. A female former 17 is arranged concentric with and displaced radially from the rings sufficiently to allow for part of the nitriding growth. Passages 42, 37 in the formers and 43, 44 in the fixture allow the circulation of the nitriding gas, the whole fixture 13 being placed in a nitriding furnace. A preliminary soaking for about 2 hours at 925 ‹ F. is given in an ammonia flow rapid enough to prevent nitrogenisation and to allow the blanks to set to the contour of the male former, followed by a normal nitriding atmosphere for about 35 hours at 995Œ5‹ F. during which the blanks grow away from the male and into contact with the female former, against which pressure is exerted and distortion of the blanks consequently prevented. The blanks are removed by opening the latch 34 and wedging apart the slot 32 and then set up in a fixture 54, Fig. 15, the section JSR being removed by grinding- wheels 54.
