Title: Improvements in or relating to the production of hydrocarbons of low boiling point by the destructive hydrogenation of solid carbonaceous materials
IPC: C10G1/00
Filed: 1933-06-17
Abstract: Solid bituminous carbonaceous materials are treated prior to destructive hydrogenation with such an amount of acid and for so long a time that the constituents soluble in acid are dissolved, the solution obtained being separated.  Hydrochloric, nitric, sulphurous, phosphoric, formic, acetic, and organic sulphonic acids may be employed or gases containing acidic substances, e.g. gases obtained in roasting sulphide ores may be used.  The amount of acid used is adjusted according to the alkalinity of the materials an excess preferably being used.  Sand contained in the coal also separates out at the same time and may be removed from the conical bottom of the treating vessel.  The washed material is then separated by filtering, centrifuging &c.  The extracted alkaline ash is preferably replaced by equivalent amounts of non-alkaline dispersive media, e.g. neutralized small coke, active carbon, florida earth, kiesel guhr, silica gel, or quartz.  2 kilograms moist brown coal containing 13 per cent ash is granulated and treated with 5--10 per cent hydrochloric acid.  The suspension is filtered and the coal after washing with water is impregnated with ammonium molybdate solution dried and made into a paste with heavy oil.  The paste is then heated in thin layers on superposed plates in an autoclave filled with hydrogen and heated to 450 DEG  C. under a pressure of 200 atmospheres.

Abstract: 625,974. Cupping; flanging. GENERAL MACHINERY CORPORATION. June 11, 1946, No. 17402. Convention date, June 11, 1945. [Class 83 (iv)] A stamping or drawing press has the movable die-supporting member formed in two parts, one part being connected to the power-transmitting means so as to be reciprocated thereby and the other part carrying the die and being pivotally connected to the first part. The invention is intended more particularly for large presses for forming vehicle bodies, in which presses, deflections of up to 0.03 inch may occur in the bed and movable slide. One form of press shown in Fig. 1 comprises a bed 20, a head 30 in the form of a rectangular framework, corner spacer members 35 and tie-rods 36. The bed supports a bolster 26 and lower die 25, while the upper die 88 is bolted to an outer slide 85 mounted on an inner slide 70 having at each end a horizontal shaft 67 on which is mounted an eccentric 65 and a driving gear 66. The slide 70 also carries supporting means for a motor 75, pulley and fly-wheel 76, clutch and control mechanism (not shown), and gearing 68 by which the two gears 66 and eccentrics 65 may be driven in opposite directions by the motor. A strap 59 surrounding each eccentric is pivoted at 57 to the lower end of a threaded link 55 which may be adjusted vertically by means of a threaded sleeve 45 to vary the position of the slide. The links 55 may be simultaneously adjusted by means of a motor 99, shaft 97 and worm-gearing (not shown). The outer slide 85 is pivotally mounted on the inner slide at a point 80 substantially midway between the ends. To prevent excessive movement of slide 85 about the pivot pins 80, the inner slide is provided at each end with pins 90 which project, with the desired degree of clearance through holes in the outer slide. In a modification, the inner slide is operated by two connecting rods from a crank-shaft journalled in the crown. In a further form, Fig. 5, the bed 200 is mounted below floor level 205 on standards 201 and carries a bolster 231 and fixed die 232. The movable die 233 is bolted to an inner slide 240 which is in turn mounted in an outer slide 250 by means of centrally-positioned pivot pins 245, turning movement being restricted by limit pins 285 as in the form already described. At each corner of the outer die is a hollow enlargement 255 receiving a plate 260 to which is bolted a housing 261 which adjustably supports the upper end of a link 265. The lower end of each link is pivotally connected at 276 with the upper end of a connecting rod 278 having at its lower end a strap 279 surrounding an eccentric 280. The four eccentrics are driven through gearing from a motor 315 so that those at opposite ends of the press rotate in opposite directions to avoid lateral strains. Specification 587,883 is referred to.

Title: Improvements in or relating to shaft couplings
IPC: B41K3/08
Filed: 1958-06-02
Abstract: 887,311. Gearing for stopping and starting machinery; shaft couplings. DEGEN, A. A. C. June 2, 1958, No. 17544/58. Class 80 (2). In a coupling in which an axially sliding member having a recess is biased to engage a mating member in the recess, axial movement brings the mating member to a wider part of the recess to allow relative movement between the members. In apparatus according to Specification 887,310, where a gear 68 drives printing-wheels 72 into a predetermined position an electric signal stops the motor driving the gear 68 and energizes a rotary solenoid 106 to move a forked member 108, about pivot 120, to move a sliding member 92 axially against a spring 100. This axial movement releases the driving-pin 93 and mating member 96 from the contacting sides of the recess 94 and provides for relative movement, due to over-run of gear 68, between the driving-shaft 91 and the printing-wheel driving- shaft 98 with which the member 96 is rigid. Movement of the member 108 allows movement of a plate 118, to which it is coupled by a spring 122, causing a roller 126 to pivot a spring- loaded pawl 128 into engagement with the teeth of a wheel 132 on the spindle of printing-wheel 72 to ensure the correct positioning of the printing figures.
