Abstract: 883,821. Screw-cutting; tool-holders. HOLZER, C., and BUSHE, M. VON, [trading as KIESERLING & ALBRECHT, TH.]. July 3, 1959 [Aug. 19, 1958], No. 23009/59. Class 83 (3). A method and apparatus for cutting serewthreads comprises the use of a tool-holder carrying a number of cutting elements which are brought successively into the cutting position by automatic means. The cutting tool is provided with three cutting faces 3a, 3b, 3c, Fig. 6, and mounted in a holder 2 rotatable in a casing head 1, Fig. 1. The end of the holder is splined in a sleeve 10 which carries a ratchet wheel 14, Fig. 2, for indexing the holder, by means of a pawl 13, through steps of 120 degrees. The pawl is carried on a sleeve 9 moved by a rack 8 forming part of a piston 7 in a cylinder 5. The lower part of the rack carries a cam strip 8a which operates a rack plunger 17 engaging a pinion 20. Rotation of the latter is transmitted to a locking plunger 24, Fig. 1, which thus releases the holder prior to indexing. A further spring- pressed plunger 25 locks the holder against rotation opposite to the indexing movement.

Title: Shortening agents and method of producing the same
IPC: A23D9/02
Filed: 1932-08-19
Abstract: Shortening-agents, e.g. hog lard, hydrogenized hog lard, mixed oils and stearine, and hydrogenized vegetable oils, are improved in creaming and other qualities by rapidly supercooling the melted shortening to such an extent that the heat of crystallization will not quite raise the temperature to the normal congealing point, withdrawing before any appreciable crystallization has taken place and permitting it to crystallize. For example, lard is melted at 120 DEG  F., passed rapidly through an internally cooled chilling machine to a temperature of 65 DEG  F. or lower, and filled into containers in which it is allowed to solidify.ALSO:Shortening-agents, e.g. hog lard, hydrogenized hog lard, mixed oils and stearine, and hydrogenized vegetable oils, are improved in creaming and other qualities by rapidly supercooling the melted shortening to such an extent that the heat of crystallization will not quite raise the temperature to the normal congealing point, withdrawing before any appreciable crystallization has taken place, and permitting it to crystallize.

Abstract: 927,777. Transformers; rectifying; automatic voltage control. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 30, 1961 [July 29, 1960], No. 23682/61. Classes 38 (2) and 38 (4). A regulated output is delivered from an A.C. source through a transformer 10 whose reluctance is varied by a control winding 22 linking an aperture 20 in the transformer core, the supply to the winding 22 being controlled in dependence on the output. The transformer secondary winding 14 is connected with biphase diodes D1, D2 through primary windings 34, 35 of a current transformer, the rectified output being fed to load terminals 41, 45. The control winding 22 is connected in series with a transistor X1 across a D.C. supply between 28 and 6. For voltage control a reference voltage derived across a Zener diode Z is fed to a transistor X4 and a sample output voltage derived from a potentiometer P is fed to a transistor X5, the transistors X4, X5 forming a differential amplifier whose output controls a transistor X3 and hence a transistor X2 which supplies bias to the transistor X1. To reduce the output voltage to zero on excess current, the current transformer secondary winding 46 provides a voltage to render conductive a transistor X6 (normally held cut-off by a battery B, Zener diode Z1 and resistors R7, R8) which then triggers into conduction a silicon controlled rectifier SR which shunts the transistor X1. Maximum saturating current then flows through the winding 22 reducing the output voltage to zero. Similar protection against excess output voltage is achieved by a signal from a potentiometer P2 through a diode D5 rendering the transistor X6 conductive. In a further embodiment (Fig. 2, not shown), two different load circuits each with its own current transformer are controlled by individual transistors X6 providing triggering pulses for a common silicon controlled rectifier.

Title: Improvements in or relating to apparatus for regulating temperature
IPC: G05D23/24
Filed: 1929-08-02
Abstract: 337,803. Pilkington Bros., Ltd., and Hogg, P. M. Aug. 2, 1929. Regulation, automatic.-The temperature of a body which is heated in an electric or other furnace is regulated by passing a current, which may be the heating current, through the body, and utilizing the variations in conductivity due to temperature variations, to control the heating means. In the application to a glass kiln 1 heated by the passage of current between electrodes 2, 3 connected through a resistance 15 to supply mains 4, 5, a solenoid 12 is connected across the electrodes 2, 3 through a variable resistance 14, and a solenoid 13 is connected across the resistance 15 through variable resistance 16. A predetermined fraction of the voltage and of the current can thus be utilized in the solenoids 12, 13 respectively, and at a predetermined average temperature of the glass the beam 7 will remain balanced. Any variation in the conductivity of the glass will result in the beam .7 becoming unbalanced, and contact will be made at 18 or 19, relay 20 or 21 will be energized, and a voltage regulator operated to rectify the voltage across the electrodes in the kiln. If the heating is not electrical, current is passed through the charge merely to measure the average conductivity and operate the regulating device.

[Class 7 (ii)] In a two-stroke engine, which is charged under pressure and wherein the cylinder exhaust ports are closed subsequently in the cycle to the closure of the admission ports, the natural frequency of the exhaust piping is such that the period of the pressure wave therein is substantially the same as the period between the opening of the exhaust ports and the closure of the scavenging ports, the second crest of the wave occurring during the period between the closure of the scavenging ports and that of the exhaust ports ; exhaust from the cylinder is thus prevented during this period. The cylinder may have opposed or superposed piston-controlled ports ; alternatively, an engineoperated poppet valve in the head may be provided. Owing to the symmetrical timing of the valves, the engine is reversible without additional gear. The engine is run at a specific speed, or telescopic exhaust piping is provided as described in Specification 442,940.

Filed: 1932-08-26
Abstract: Rubber articles such as boot soles, heels, combined soles and heels, or stiffening-members for the peaks of caps, which are usually formed by stamping or cutting sheet rubber, are manufactured by extruding a bar of plastic rubber through a die having the profile of the finished article, and then cutting the extruded material transversely into slices to form the separate articles, which are subsequently vulcanized.  In making combined soles and heels, the transverse cuts may either produce whole slices of the thickness of the heel, leaving the sole part to be reduced in thickness by a subsequent cut, or they may be of the thickness of the sole throughout, leaving an additional heel-piece to be cemented on.
