Title: A new or improved process of or apparatus for blueing, cleaning and polishing tacks,nails and the like
IPC: C23C8/14
Filed: 1920-01-08
Abstract: 160,600. Bullock, C. T. Jan. 8, 1920. Rumbles and tumbling-barrels.-The processes of shaking, blueing, and cleaning nails, tacks, &c. are carried out in the same apparatus, which comprises a rotatable cylinder with means for directing a series of high-pressure gas jets within it and means for inducing a blast of air through the cylinder. The cylinder 1 is rotatably mounted on rollers 2, one pair of which is driven from the pulley 5. Longitudinal baffles 16, which may be disposed radially or inclined at any suitable angle, are attached to or near the inner surface of the cylinder. The tacks are introduced through an opening normally closed by a lid (not shown) until their level is just below the tube 6. The cylinder is first rotated to free the tacks of needle points formed in manufacture on their shanks. After the blueing process, the cylinder is again rotated and a blast of air is induced through the aperture 10 by means of a fan 13 to remove swarf, scale, and dirt and for polishing. A fixed or detachable cup-shaped grid 16a perforated round its sides prevents the tacks from escaping into the conduit 12. A shutter 17 disconnects the fan during the heating process. The tacks are discharged into one or more hoppers on the lid being opened when brought to the bottom by means of a hand-operated crank, &c. According to one Provisional Specification, the drum has a second series of baffles, forming with the baffles 16 a series of V-shaped elements; and means are provided for rotating the drum in the reverse direction.

Title: Improvements in or relating to apparatus for cleaning gear casings or the like
IPC: F16N33/00
Filed: 1930-01-09
Abstract: 338,791. Wertz, A. L. Feb. 11, 1929, [Convention date]. Shop accessories.-In apparatus for cleansing gear casings, containers, &c. by flushing the parts to be cleaned with a fluid and then withdrawing the fluid together with the dirt, grit, greases, &c, from the casing &c., a single conduit is used to convey and withdraw the fluid by means of an ejector of the Venturi type with a controlled outlet. The pump and motor associated with the apparatus comprise a movable unitary structure, and means to prevent overloading of the pump is provided when the ejector is shut off. A tank 10 is mounted upon a truck comprising a frame 12, wheels 14, and pipe uprights 16 to which it is braced. The tank has a shelf 24 supporting a straining and settling receptacle 26. A screen 30 is secured to an opening in the receptacle 26. A base plate 34 is welded to brackets 36 carrying handles 38 which fit over the uprights 16 and are normally secured thereto by set screws. An electric motor and a pump are secured to the plate 34. The motor inlet is connected to a suction pipe 48 carrying a strainer 50 in the tank 10. The motor outlet is connected to a branch member 52 provided with an outlet 54 carrying a spring-loaded non-return valve, and provided with an ejector carrying a nozzle 72 secured in a body 70 forming a Venturi passage way. The bore 76 is connected to a flexible conduit 78 which may act as a suction or discharge outlet, and to a passage 84 in a valve casing carrying a plunger valve 88 which is operated by a lever through a handoperated wire or chain against the resistance of a spring 94. The plunger 86 is of smaller diameter than the passage 84 and cannot shut off completely the ejector discharge therethrough. In a modified form of valve, a disc-shaped slide valve is mounted upon a spring-controlled arm, and moves between adjustable stops to bring the ejector outlet and discharge more or less into register. A control valve 106, Fig. 6, with a pistol-grip handle 108 is screwed to the end of the conduit 78. The valve comprises a spring-pressed lift valve, the stem 120 of which is engaged by a cam projection 140 on a. trigger 136. In operation, the tank is usually tilled three-fourths full of cleaning fluid and the motor started. The fluid passes up pipe 48 and is discharged into the ejector 70. The nozzle 142 is inserted into the casing and the trigger valve opened. The contents of the casing, if sufficiently fluid, are withdrawn by suction. If not, the plunder 88 is moved to close the bore 84. The cleansing-fluid is then forced outwardly through the conduit 78, and may be used to spray into the casing. When the grease &c. has been loosened by spraying, the ejector is used in the ordinary way, the material sucked from the casing is discharged through the pipe 98 into the receptacle 26. When the pressure of the pump discharge rises, the check valve in the branch 54 opens, and the discharge passes into the tank 10.

Title: Frequency controlled resonant regulator
Inventor: WENDT FRANK STARR
IPC: H02M7/5383
Filed: 1994-06-23
Abstract: The primary winding of a high leakage inductance power tranformer is coupled to a source of unregulated voltage and to a square wave voltage generator that includes first and second alternately conducting output switching transistors. A voltage controlled oscillator establishes the operating frequency of the voltage generator. A resonating capacitor is coupled to a transformer secondary winding that is loosely coupled with the primary winding. The capacitor forms a series tuned circuit with the leakage inductance between the primary and secondary windings of the transformer. The operating point of the tuned circuit voltage verses frequency characteristic curve determines the amplitude of the generally sinusoidal output voltage across the secondary winding, in accordance with the operating frequency of the square wave voltage generator. A feedback circuit senses the amplitude of the output voltage and varies the frequency of the voltage controlled oscillator to regulate the output voltage.

When the rest of the solid argon is reduced and an evaporation amount is reduced, a temperature which is reduced from 151k is raised to 151K and more. When the temperature exceeds 273K, ices fuse, and gas purge is carried out by inactive gas so as to discharge water. After moisture is discharged, inactive gas purge is stopped, roughing is carried out in a pressure level which is not interfered with starting of the cryopump (at d part). The cryopump is started, and cooling is started. When a temperature in a second step heat load stage is decreased to 20k and regeneration is completed, regeneration is completed at about 140 minutes.
