Abstract: 383,994. R÷ntgen-ray apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Wantz, J. B. ; 324, North Harvey Avenue, Oak Park, Illinois, U.S.A.) Aug. 31, 1931, No. 24446. Convention date, Aug. 30, 1930. [Class 98 (i).] An X-ray diagnosis table structure comprises in combination (a) a frame for a table top which is supported by pivotless arcuate side members 120, driven by gearing engaging a rack 124 in each side member ; (b) guiding supports 23 for the side members ; (c) paired tubular members 126, 130, 132 secured to the side members 120, which provide tracks for an X-ray carriage apparatus 190 (including a screen and diaphragm), and/or a carriage for a Bucky diaphragm 140, and housings for counterpoise. weights ; and (d) pedals 65 by which a handbrake is released and a switch operated to energize a motor for tilting the table in either direction. The arcuate side members 120 ride on roller bearings. Further, one of the arcuate side members 120 has two limit stops 98, 99, Fig. 4, to engage a projection 97 on the switch arm 90 to return it to a neutral position, and thereby, through a sector gear 82 on the switch arm 91 and a sector gear 80 on a transverse shaft 60 of the table base, to return whichever pedal 65 is depressed to normal position, the band brake on the motor shaft being also automatically applied. The two pedals turn the shaft 60 in opposite directions and thereby, through the sectors 80, 82, rotate the switch on its central pivot 93. The switch comprises the two cross-arms 90, 91 and 94, 94a, the latter being insulated and having contacts 95 at opposite ends engaging two series of contacts in opposite quadrants on a base-plate 100. A spring-controlled sliding Y-member 85 holds the switch in neutral position by means of a curved slotted arm 86 engaging a pin 88 on the switch arm 90 and a pin on the opposite arm which engages a projection on the cross-arm 91. The carriage 190, Fig. 2, for the X-ray tube and screen is moved along the table top by a handle 188, the carriage being mounted by rollers between the tubular members 130, 132, and by a branch roller engaging the sides of the upper tubes 130. The carriage is connected by cables over rollers to counterpoises which run on rollers within the tubes 132. The tube and screen are also transversely adjustable. The Bucky diaphragm carriage 140 slides between the tubes 126, 130, and is connected by cables over rollers to opposite ends of a counterpoise similarly mounted on rollers within one of the tubes 130. An end frame 20 with insulated uprights for the tube leads may be mounted at the end of the table structure by side members 22 to the supporting base of the table. Supporting structures may be mounted on the side frames 23 for alternative mountings for an X-ray tube and accessories.

Title: Tightening method and system
IPC: B25B23/14
Filed: 1975-09-19
Abstract: 1526946 Measuring axial load on bolts electrically STANDARD PRESSED STEEL CO 19 Sept 1975 [19 Sept 1974] 38495/75 Heading G1N [Also in Divisions B3 and G3] A threaded fastener is tightened by rotation with a wrench thereby increasing the applied torque until the yield point of the fastener is reached, when the torque is no longer proportional to the angle of rotation. The axial load is obtained from the predetermined torque at yield point/axial load characteristic, shown in curve D of Fig. 2, and the coefficient of friction F between the fastener and its mating surfaces is the slope of the appropriate axial load/torque characteristic F1-F3. For any particular type of fastener having a diameter D, the relationship between applied torque T and resulting axial load L is T = LFD, and the torque Td for a derived axial load Ld can be determined. As shown for use with a wrench 12, Fig. 4, operated by a pneumatic motor 14 controlled by valve 20 to produce tightening torque or valve 21 to produce loosening torque, the torque developed during tightening is measured by strain gauges 25 and the angular rotation by toothed member 26 and pick-up 28. A comparator 34 determines the change in torque between consecutive pulses from pick-up 28, i.e. the torque/rotation gradient, and stores the maximum value at 36 for subsequent comparison at 38 with the instantaneous value. When the latter falls below a pre-set proportion of the maximum value, defining the yield point of the fastener, an output signal closes valve 20, to stop motor 14, and closes switch 42 to feed the torque at yield point signal to a memory device 40 storing curve D of Fig. 2, which develops the corresponding axial load signal. This is compared at 46 with the desired axial load Ld developed at 48. Normally a difference signal is produced by comparator 48 which is fed via closed switch 47 to calculator 50 which determines the torque Td for the desired axial load Ld, to be stored at 54. The torque is then reduced until it is 5% below Td and finally increased until it is equal to Td.  Another method of obtaining a desired axial load on a screwed fastener is based on the fact that the axial load is proportional to the angle of rotation independently of the frictional coefficient, which only affects the torsional load and hence the yield point. In an embodiment using this method, Fig. 6 (not shown), the rotation at yield point determines in a memory store the corresponding torque, axial load and coefficient of friction. As above the rotation providing the desired axial load is calculated and the fastener loosened from the yield point until the desired rotation is produced.

Title: Improvements in or relating to hydroforming processes employing alumina catalysts
IPC: B01J21/04
Filed: 1958-12-02
Abstract: In the hydroforming of petroleum with a hydroforming catalyst supported on alumina, the alumina contains at least 80% of eta alumina and is prepared by hydrolysing a hydrocarbon solvent solution of an aluminium alcoholate with dilute ammonium hydroxide solution at a temperature above 100 DEG F. up to 175 DEG F., and thereafter ageing the hydrous alumina slurry for at least one hour at a temperature below 80 DEG F. the ammonium hydroxide solution has a concentration of 1.8 to 3.4% by weight of ammonia and is employed in an amount from 1 to 10 volumes per volume of aluminium alcoholate solution.  The alcoholate may be derived from lower alcohols but C5 and higher alcohols, which are water-immiscible, are preferred; the alcohol must be anhydrous. The hydrocarbon diluent is preferably a petroleum distillate boiling at 200-500 DEG F. but heptane, octane, toluene, or xylene may be used.  Alcoholate formation is catalysed by mercuric chloride, iodine or aluminium halides.  In the preferred operation, a solution of aluminium amylate in the hydrocarbon solvent is hydrolysed by slow addition of the dilute ammonium hydroxide solution whilst agitating and the hydrous alumina so produced is aged for three to four days at 60 DEG F.  The alcohol which is reformed by the hydrolysis step forms a separate phase together with the hydrocarbon diluent.  Alternatively, if a water soluble alcohol is employed, it must be recovered from the aqueous phase by distillation.  The alumina slurry containing the beta trihydrate is dried at 200-400 DEG F. and converted to eta alumina by dehydration at 400-1400 DEG F., preferably in the presence of air.  In the preparation of a hydroforming catalyst, the eta alumina so formed, or the beta trihydrate precursor, may be treated with a catalyst component such as molybdenum, vanadium, tungsten or chromium oxides, calcium or cobalt molybdate or preferably platinum or palladium.  The catalyst may contain 5-20% of molybdenum oxide, up to 40% of chromium oxide, 0.001-2% of platinum or 0.5-5% of palladium.  The preferred, platinum, catalyst is prepared by treating the hydrous, dried or calcined form of the eta alumina with aqueous solutions of inorganic platinum-containing compounds, especially chloroplatinic acid, potassium platinum chloride, platinum disulphite, tetrammino platinochloride, potassium platinonitrate, dichlorodiammino platinum, ammonium platinonitrate, and dinitrito-diammino-platinum.  The final catalyst is subjected to reduction with hydrogen at 200-1000 DEG F. at pressures up to 1000 pounds p.s.i.g.  The catalyst, before or after impregnation with a catalytic component, is preferably treated with an aqueous dilute combined acid solution containing an oxidizing acid such as nitric, perchloric or hypochlorous acid, together with a hydrogen halide; nitric acid and hydrochloric acid are preferred.
