Title: Bottle stoppering apparatus
IPC: B67B1/04
Filed: 1952-12-19
Abstract: 721,735. Stoppering. UPJOHN CO. Dec. 19, 1952 [Dec. 26, 1951], No. 32282/52. Class 125 (2). In apparatus for inserting flange-headed stoppers into bottles advanced by a conveyer between guide rails 12 and held stationary under a stoppering head by the means described in Specification 721,736, the stoppers C are fed by a selector B which vibrates an inclined shoot 34 the bottom of which has a slot for the stopper shanks and are forced through the slot by a ram 37 reciprocated above the shoot to force the stopper into a bottle held in axial alignment therewith. The shoot, Fig. 8, comprises a top 59 reinforced by a plate 60, sides 57, 58 and bottom flanges 61, 62 defining the slot. Four pillars 16 on the base frame 1 support a plate 21 from which is suspended at an adjustable height a frame comprising top and bottom plates 23, 28 joined by vertical members 26, 27. The ram 37 is reciprocated in a boss 30 fixed to plate 28 by a hydraulic plunger 36 mounted on the plate 21. Resilient means 102 support the lower end of the shoot 34 in alignment with a channel 38 in the plate 28, the top of the channel being closed by an extension 59a of the shoot and the bottom of the channel having a slot defined by lips 40 for the stopper shanks. By the vibration of the shoot 34, stoppers are fed into the channel 38 until they abut an end stop surface 41 in which position they are aligned with the ram 37. When the latter descends it forces the stopper through between the lips 40 which are partly cut away at 93, 94. Either the stopper head or the lips 40 are of resilient material to allow this action. The plunger 36 is actuated in synchronism with the bottle registering means and will only be actuated when a bottle is present in the stoppering position because the bottle actuates a trigger controlling the plunger. In a modification, Fig. 13, the shoot is beneath the ram 37 and has an end stop 97 supported by resilient ribs 96 in a fixed bracket 100.

Filed: 1925-12-22
Abstract: 256,117. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Dec. 22, 1925. Cut-out arrangements.-In an automaticallyreclosing circuit-breaker system, when the main circuit-breaker 2 opens on overload due to the opening of its holding coil 3 by the action of the overload relay 5 carrying a series coil 6, the relay is held open by a holding-out coil 7 and back contacts 9 on the circuit-breaker connect a low resistance R<2> in parallel with the load. The coil 7 is in shunt with the circuit-breaker and when the circuit-breaker is open is in series with the load. A relatively-high resistance R<1> is connected in series jointly with the coil 7 and the resistance R<2>. When, after the circuit-breaker has been released to assume the open position, the resistance of the load increases sufficiently in relation to the parallel resistance R<2> the current in the coil 7 in series with the load decreases to the point at which it is inadequate to hold out the overload relay 5 which closes and completes the closing circuit of the main circuit-breaker. The coil 7 instead of being arranged on the overload relay may be the operating coil of a separate holding-out relay with its contacts in the lead 10.

Patent GB-849313-A (GB)
Title: A metallurgical process for treating steel
IPC: C21D8/00
Filed: 1957-10-17
Abstract: A process for treating steel which strain hardens and hardens by some mode of precipitation when worked at a temperature between 350 DEG F. and the lowest critical temperature for the steel composition comprises rolling or advancing the steel through a die to effect reduction in cross-section while the steel is at a temperature within the above range and then heat treating the steel subsquent to the elevated temperature reduction step.  In an example a hot-rolled, pickled and limed bar, rod, wire or tube of non-austenitic steel having a pearlitic structure in a matrix of free ferrite is extruded or drawn through a die whilst at a temperature within the range of 450 DEG  to 850 DEG F. and then heated to the austenitizing temperature (1500 DEG F.), for one hour, quenched in oil and tempered.  In another example the heat treatment consists in heating the steel above the transformation range (1500 DEG -1600 DEG F.), followed by a partial quench to a temperature within the range of 200 DEG F. to the lower critical temperature of the steel.  In another example the heat treatment after the reduction step consists in martempering the steel by heating to a temperature above its transformation temperature and quenching the steel in a bath maintained at a temperature slightly below the Ms range until transformation to martensite is complete and then cooling the steel to room temperature.  In a further example the steel is austempered by heating above its transformation range (1500 DEG -1600 DEG F.), and quenching at a temperature slightly above the Ms range and at a rate to extract heat from the steel to avoid passage through the austenite range and then cooling.  In another example the steel is subjected to diffusion transfer after the reduction step by either carburizing, nitriding, cyaniding, chromizing or carbonitriding followed by cooling to room temperature.  Specifications 761,150 and 761,151 are referred to.
Patent GB-521131-A (GB)
Title: Improvements in or relating to cop winding machines, especially jute cop winding machines
IPC: B65H54/14
Filed: 1938-11-09
Abstract: 521,131. Cop-winding machines. HAYES, J. Nov. 9, 1938, No. 32486. [Class 120 (ii)] A solid cop is formed by a cop - winding machine in which the cop is supported in a conical recess formed by three rotatable elements, one of which imparts the driving motion to the cop. Vertical spindles 3 are arranged along the sides of the machine each having a pulley 4 driven from one of the cylinders 2. Rocking shafts 6 are supported at the top of each side, and arms 7 with guides 8 for the jute or like yarn which passes first over the guides 15, 17 when it is supplied from the rolls 10 mounted on the frame 12. A cone 19 is mounted on the top of each spindle, and an inclined cylinder 21 mounted in a bracket 20 is arranged at the rear of each pair of cones thereby forming a conical recess which supports the nose of the cop on three convergent lines. Each cop holder consists of an inverted frusto-conical member 22 with a projecting tapering pin 22c; the member 22 is attached to a cross bar 24 sliding on guide rods 25. The yarn from the guide 8 is passed into the pin 22 and the guide is raised and lowered in known fashion; the cop is formed and engages the cones 19 which take up the drive as the holder is lifted. The resultant cop is without the usual central hole. A razor blade 27 is located in the cop holder with its edge across a slot 28 at the side of a projection 29 which guides the yarn into the slot at the end of the wind. Shafts 31 carry cams 32 corresponding to each inclined cylinder 21, the bracket of which is carried on an arm 34 pivoted on a shaft 35 and provided with a pin 36 to engage the cam 32 ; this normally holds the cylinder in a position to support the cop 9. A second cam is arranged behind each cam 32 and supports a weighted lever 41 which operates to reset the parts after a cop has been released. The shaft 31 makes one revolution while the cop is being formed and at the end of it the pin 36 falls into the recess 33 in the cam 32. The arm 34 and the attached cylinder 21 drop so that the cop is freed and falls through the tube 38 to the conveyer band 49. During the fall of the cop the holder 22 drops into engagement with the cones 19 and the yarn passes into the slot 28 where it is severed by the razor blade 27. A few seconds after the cop has dropped, the weighted lever 41 is permitted by the second cam to fall and cause a linkage to raise the arm 34 to its normal position so that the operation can be repeated. A treadle 52 is arranged to disengage the drive to any spindle if the thread breaks.

Title: An improved television system
IPC: H04N5/30
Filed: 1935-11-25
Abstract: 466,604. Television; cathode-ray tubes. TRUTOLIFE TELEVISION'CO., Ltd., and SHANNON, D. S. B. Nov. 25, 1935, No. 32633. [Classes 39 (i) and 40 (iii)] A scanning device comprises in combination a light source consisting of a cathode-ray tube 5 having a fluorescent screen 10a substantially the whole of which is bombarded simultaneously by the cathode beam, and a deflecting system comprising a pair of piezoelectric crystals 32, 37 through which the light is projected, the crystals being stressed electrostatically in mutually perpendicular directions at the frame and line frequencies respectively, so that the light transmitted by the crystals is refracted to scan the object or a screen. In the receiving-apparatus shown, in the cathode-ray tube a modulating electrode 9 is interposed between the cathode 6 (surrounded by an iron screen electrode 7) and the obliquely disposed anode 10, which has a fluorescent coating 10a of willemite, calcium tungstate, barium platino-cyanide or the like. The anode may be supported by tubes (not shown) adapted to provide water circulation for cooling. High-frequency high-voltage oscillations are applied between the anode and cathode of the tube 5, through a transformer 23 connected to an oscillating valve 18, which is supplied through a transformer 14 from an alternating low-voltage supply 13. Oscillations which are 180‹ out of phase with those applied between the anode and cathode of the tube, and of lower voltage, are applied through a condenser 28 across the cathode 6 and screen electrode 7. By this means the generated cathode ray is intermittent at a frequency higher than the highest picture frequency. Received picture signals are applied across the terminals 30. The modulated light emitted from the fluorescent screen, focused to a spot by a lens 31, Fig. 3, passes successively through piezo-electric crystals 32, 37 on the appropriate faces of which are pairs of electrodes 33, 38 to which saw-tooth oscillations at frame frequency and line frequency respectively are applied. The modulated ray is thereby deflected vertically at the frame frequency by the crystal 32, and horizontally at line frequency by the crystal 37, and the picture is reconstituted on a screen 40. A constant electrostatic field may be produced between the crystals by wire gauze electrodes 42. The system described may be used for scanning in a transmitter, the modulating electrode 9 being then omitted or rendered inoperative.
