Title: Method of manufacturing spiral drilling bits and the like
IPC: B21K5/02
Filed: 1926-10-15
Abstract: 273,543. Leidecker, F. R. Oct. 15, 1926. Forging rock drills; dies. - In a method of making twist drills by forging the spiral grooves by means of a pair of dies having ribs adapted to form a partial turn of the spiral grooves at each application and in which the feeding of the blank is effected by rotating it whilst in engagement with the dies when the pressure is removed, wings of predetermined cross-section on an oversize core are formed by a preliminary operation and the surplus metal is forced from the core during the twisting operation to compensate for the elongation of the wings due to the twisting. The radial wings are produced by a pair of dies 1, 2 with recesses 5 and spaces 4, the sides of the recesses 5 diverging towards the spaces 4 and the sides of the spaces 4 diverging from the rounded shoulders 7. The end walls of the recesses 5 are concaved at a, b and the end walls 10 of the spaces 4 converge towards the meeting faces of the dies. The action of the dies on a portion of the billet produces four wings thereon, two with diverging sides by the spaces 4 and two with converging sides by the recesses 5. The billet is turned through a right-angle and the same portion again acted on by the dies, which results in all four wings being brought to diverging formation 15, Fig. 4, with rounded outer faces 14. These operations are repeated as the billet is fed forward step by step. The wings are twisted by a pair of dies 10, 11, Fig. 2, having recesses 12 with helical ribs 13, by which first one pair of the wings 17 and then the other pair are twisted as the bit is fed forward step by step between the dies; Fig. 5 shows the cross-section of the finished drill, metal from the oversize core 16, Fig. 4, having been forced by the twisting operation into the wings.

Title: A synchronous clocking system
IPC: H03M1/00
Filed: 1965-06-18
Abstract: 1,096,647. Synchronizing oscillators. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 18, 1965 [June 30, 1964], No. 25824/65. Heading H3T. [Also in Division G4] In a synchronous clocking system, a variablefrequency clock circuit supplies a train of clock pulses synchronized with electrical signals applied thereto via gating means which after an initial period is enabled during only a part of the clock cycle, by the clock circuit output, so that electrical signals out of phase with said clock circuit by more than a predetermined amount are not supplied to the clock circuit by said gating means except during said initial period. The system is used for the self-clocking of phase-modulated binary data from a magnetic store. The data train, starting with a burst of all zeroes (or all ones), is differentiated 15, limited 20 and then supplied to a " peak pulser " 25 which produces a pulse for every negative to positive zero crossing on one line 25a and a pulse for every zero crossing on another line 25b. Arrival of the burst causes a burst detector 70 to trigger a single shot 75 which for a predetermined period gates the pulses on the first line 25a from the peak pulser 25 through a latch 46 to start and synchronize the clock 45 (the frequency of which is varied by changing the charging rate of a capacitor therein). After this period, when the information will be arriving, the pulses on the second line 25b from the peak pulser 25 (" every zero crossing ") are used to synchronize the clock 45 via a second gate 35 which also receives the inverted single shot 75 output, the latch 46 output (to prevent initial starting of the clock 45 by a pulse on the second peak pulser line 25b) and the outputs of two " level setters " 85, 90. The level setters 85, 90 are threshold devices connected to the clock 45 output. The clock 45 output, which is a repeating sawtooth, is squared off 50 and compared 55 with the limiter 20 output to produce a pulse for each one bit and no pulse for a zero bit. Burst detector 70 (Fig. 4).-The burst is applied at 70d to cause transistor 70f to conduct thus charging an RLC integrating circuit 70a, 70b, 70c. Schmitt trigger 70j produces an output when the voltage between resistor 70a and inductor 70b is sufficiently negative.

Title: Improvements in or relating to the separation of fatty acids and fatty acid derivatives
IPC: B01D71/24
Filed: 1948-10-06
Abstract: A method of separating the components of fatty oils applicable to the extraction of vitamin A fatty acid ester from fish liver oil and the separation of partial glycerides such as the mono-, di- and tri-laurines, consists in dialyzing such mixtures, by means of a membrane of a high polymeric substance which exhibits swelling with fatty oils, such as rubber, methyl or ethyl poly-acrylic acid ester, polyvinyl chloride, or polyvinyl chloride copolymerized with a small amount of polyvinylidene chloride.  The rubber may be vulcanized. The course of the dialysis may be influenced by the polarity of the rubber, as when rubber containing polar groups such as the nitrile group is used, by the polarity of added solvents, by the use of solvents outside the membrane, and by the temperature.  In the case of vitamin A, the dialysis is effected in the presence of petroleum ether while in the case of the separation of glycerides, a mixture of petroleum ether and alcohol is used.  U.S.A. Specification 2,408,625 and Specifications 592,587, [Group III], and 592,625, [Group II], are referred to.ALSO:A method of separating the components of fatty oils or their derivatives containing oily constituents, or of extracting substances contained therein, consists in dialyzing such mixtures, with or without a solvent, by means of a membrane of a high polymeric substance which exhibits swelling with fatty oils. The high polymeric substance may be rubber, which may be vulcanized, methyl or ethyl poly-acrylic acid ester, polyvinyl chloride, or polyvinyl chloride copolymerized with a small amount of polyvinylidene chloride.  The process is applicable to the extraction of vitamin A fatty acid ester, to the separation of partial glycerides, and to the treatment of polymerized oils. The course of the dialysis may be influenced by the polarity of the rubber, as when rubber containing polar groups such as the nitrile group is used, by the polarity of added solvents, by the use of solvents outside the membrane, and by the temperature. Examples are given of the demucilaging of crude groundnut oil, of the separation of soya oil phosphatides, of the extraction of vitamin A fatty acid ester from fish liver oil, of the extraction of polymers from dehydrated castor oil and from linseed oil, of the separation of partial glycerides (mono-, di-, and tri-laurines), of the purification of benzine extractions of fat from the nickel catalyst used in the hardening of fat, of the purification of herring oil, and of the purification of refinery acid oils from the splitting of refinery soap.
