Filed: 1933-09-05
Abstract: 410,377. Hydraulic transmission of power. FORTUNA-WERKE SPEZIALMASCHINENFABRIK AKT-GES., Cannstatt Stuttgart, Germany. Sept. 5, 1933, No. 24587. Convention date, Nov. 26, 1932. [Class 69 (ii).] Means for producing, in a grinding-machine or similar machine tool, a feed movement approximating closely to a " plunge cut," comprises ratchet and pawl mechanism 2, 4 on the feed shaft 1 operated at short intervals by a hydraulically operated piston 13, which, together with a valve 15, 15<1> is located in a hydraulic circuit independent of other circuits of the machine. The pawl is carried by an arm 3 lifted, against a spring 5, by a cam 6, which is oscillated by a pinion 10 and a rack 12 on the piston 13 to which fluid is supplied by a conduit 14 through a throttle member 17 rotatable in the piston casing 9 by worm gearing and a hand-wheel 19 ; the valve 15, 15<1> also is located in the casing 9 and has driving pistons 16, 16<1> thereon. Fluid passes through one of two throttle apertures 20, 20<1> in member 17 to the piston and moves it at controlled speed until the cam 6 has given maximum lift to the arm 3, when the piston uncovers an unthrottled opening 26 or 26<1> and is thus rapidly driven to the end of its stroke. As the piston moves, grooves 30, 30<1>, 31, 31<1> therein uncover, near the ends of the strokes, ports 27, 27<1>, 34, 34<1> thus admitting pressure fluid to one of the pistons 16 or 161, and opening the other to exhaust, whereby the valve 15, 15<1> is moved to cause reversal of the movement of the piston 13, a feeding movement being given to the arm 3 in the first half of each stroke of the piston. The plunge cut feed may be discontinued and feed given at the ends of the strokes of the work or tool slide of the machine, and for this purpose, the member 17 is turned to close the apertures 20, 20<1> &c., therein, fluid being admitted intermittently to the piston 13 through conduits 35, 36 and bores 37, 38 in the member 17.

Abstract: 727,688. Making turbine and compressor blades. THOMPSON PRODUCTS, Inc. Oct. 2, 1952, No. 24698/52. Classes 83 (2) and 83 (4). Forging; rolling; working at specified temperatures.-A method of making precision parts of complicated contours with consistent dimensions, particularly blades for gas turbines, comprises hot forging a work-piece to the approximate shape required and then cold forging it to the exact shape and dimensions required. A turbine or compressor blade is made by extruding a cylindrical bar to form a headed rod 12, Fig. 3, and rolling the rod between rolls 16, 17 to straighten the stem portion 13 and make it concentric with the head portion 15. The stem and neck portion 14 are then ground to predetermined dimensions in a centreless grinder and a number of ground blanks are tumbled in a revolving drum and washed. The blank is then heated to 1800- 1900‹ F. and rough forged between dies 21, 22, Fig. 6, after either the blank or the dies have been coated with colloidal graphite. Locating buttons are formed on the blank during forging. Flash metal such as 23a is then removed by shearing, which may be done while the blank is hot or alternatively it may be re-heated for this purpose, and the blank is then cleaned by nozzle blasting with an abrasive material which thereby removes the graphite coating. The blank is again heated to 1400-1450‹ F. and forged between dies after being re-coated with graphite, the flash metal is removed and the blank is annealed and then cleaned. The blank is then cold forged between highly polished dies 32 (Fig. 14), at pressures of 150-300 tons per square inch in an hydraulic press which produces the final aerofoil section and twist of the blade. Flash gutters 33 are disposed adjacent the aerofoil portion 36 in the dies 32. Soap solution is used as a lubricant during the cold forging. Flash metal is then removed by grinding and an un-forged end portion of the stem which has been used to grip the blank is removed. The blank is washed, hardened and tempered, the locating buttons, which have been used to locate the blank in the forging dies, are removed by grinding, another wet blasting treatment is effected to improve the surface finish and a dovetail groove 40, Fig. 19, is broached in the neck portion 41b. Finally the aerofoil section 41a is cut to the desired length. Chromium steel is used for the blade.

Title: Improved manufacture of crimped artificial fibres
IPC: D01F2/04
Filed: 1936-09-10
Abstract: In the production of crimped artificial fibres from cuprammonia - cellulose solutions, the freshly-formed threads which have been spun under tension, particularly those which still contain chemically-bound copper, are subjected when free from tension to a treatment with steam, hot water, or a hot salt solution.  Threads made by the stretch-spinning process may be treated.  The threads may be cut to staple length and then subjected to the hot treatment.  Hot concentrated solutions of sodium sulphate, acid sodium sulphate, or ammonium sulphate may be used.  The hot treatment has a shrinking effect, and well-crimped fibres are obtained.  In an example, cuprammonia-cellulose solution is extruded into water or dilute acid flowing through a spinning funnel and the thread still containing copper is passed to a drawing apparatus and cut to staple length. The cut fibres are placed in a bath of boiling water until well crimped, and then treated with acid and water.  Instead of using the boiling water bath, the fibres may be steamed during the cutting operation, or a hot alcoholic solution of sodium sulphate may be used.

Title: Therapeutic bone mixture
IPC: A61K35/32
Filed: 1956-08-14
Abstract: A bone mixture for application to incisions to enhance clotting and for use as a bed or filler between bone sections in general surgery and dentistry consists of pulverized viable non-human animal bone and a plasma clot as a binder for the said pulverized bone, the plasma clot substance, e.g. blood plasma, being obtained from the same species of animal, but not necessarily the same animal, as that from which the bone is obtained.  Bone is preserved according to the method of Specification 827,746 by removing bone from a healthy, non-human animal body under sterile conditions and placing the removed bone in a container having therein an antibiotic such as penicillin or a sulpha drug such as sulphadiazine, and blood plasma or blood serum from the same species of animal from which the bone was removed.  Bones may be from domestic animals, e.g. sheep, bovine, hogs, dogs, cats and horses.  The bone so preserved is divided into small pieces, by e.g. sawing, and is then pulverized without cauterization in a grinder or mixer, and is then mixed with the plasma clot substance under sterile conditions at about 40 DEG  F. In the presence of the bone, the blood plasma forms a clot, the calcium from the bone reacting with the prothrombin and thromoplastin from the blood plasma to form thrombin which in turn reacts with the fibrinogen of the blood plasma to form fibrin.  A suitable gel is formed with 10 parts of bone and 1 part of plasma clot.  If not used immediately, it must be maintained under sterile conditions at 40-50 DEG  F.  Preferably the mixture is enclosed in an osmotic membrane immersed in blood plasma.

Abstract: 462,536. Valve amplifying circuits. WHITE, E. L. C. Sept. 7, 1935, No. 24977. (Class 46 (v)] A direct-coupled amplifier for handling a fre. quency range from four megacycles to zero, has the second valve V2 connected as a cathode follower, thus reducing the capacity shunting effect of the anode impedance R1 in a similar manner to that disclosed in Specification 448,421. The cathode impedance R2 is made equal to the impedance R1 and large compared with the inverse of the mutual conductance of valve V2. The output voltage across impedance R2 is substantially equal to that across impedance R1, the output impedance seen from terminals C is low, and the valves V1, V2 together draw a constant current from the battery B, thus avoiding the necessity of providing decoupling means when the battery B is used to supply other pairs of valves similarly connected. Three pairs of valves are disclosed in Fig. 2 (not shown), the first being connected to the second by a condenser and biassing resistance, and the second to the third by a floating battery.
