Abstract: METHOD AND APPARATUS FOR PRODUCING DRY            COMPRESSED AIR FOR ELECTRICAL GEAR                 Abstract of the Disclosure An apparatus and a method for producing dry, compressed air to be used for electrical switchgear, es-pecially for high-tension switchgear, is disclosed in which humidity is extracted from the air in a subsequently arranged sorption dryer, with one portion of the dried air being used to regenerate a drying agent of the drying apparatus.  The drying apparatus includes a cylindrical inner housing which is used for the pre-drying of the air, an outer housing which surrounds the former in jacket form for the final drying and a desorption volume.  An electric heating rod protrudes con-centrially into the inner housing and is covered by either a baffle device or a pipe so that a ring-gap is created between two components, with the ring-gap divided into two halves. The air is pre-dried in the first drying chamber prior to its entry into the compressor, with the temperature of the air being kept above the dew point during compression and cooling.  The air is then heated prior to a second or final drying process with the remaining moisture being removed during the course of this drying process so that the entire humidity of the air is extracted in the steam phase.

Abstract: (Case No. 6878) BRAKE APPARATUS WITH A COMBINED  BRAKE CYLINDER AND RESERVOIR                ABSTRACT OF THE DISCLOSURE    This invention relates to a novel railway vehicle brake apparatus that comprises a brake cylinder device having two tandem-connected pistons of unequal size, the larger of which is provided with a check valve and cooperates with a hollow cylindrical body in which it is slidably disposed to form on its respective opposite sides two fluid pressure storage reservoirs wherein is stored fluid under pressure for effecting a brake application.  This brake apparatus further comprises a novel brake control valve device that is so responsive to a reduction of pressure in a train brake pipe as to first cause simultaneous shifting of both pistons in a brake-applying direction and a transfer of fluid under pressure from one side of the larger piston to the other until a chosen braking force is transmitted through brake rigging to press brake shoes against the wheels of a vehicle, Thereafter, the control valve device is operative to release fluid under pressure from the one side of the larger piston to atmosphere to increase the braking force pressing the shoes against the wheels.

Abstract: AIR SLID FREEZER SYSTEM                            Abstract A method and system for preparing comestibles for frozen storage in which pressurized freezing air Is utilized in conjunction with a substantially flat conveyance surface, both to aid in or contribute to the conveyance of the packages or containers well as to effectuate the rapid freezing of the comestibles ,therein during the course of . such conveyance through the system. In the preferred embodiment, the elongated conveyance deck is of space saving substantially helical form with successive descending turns underlying one another and with the space surrounded by the turns forming part,of a plenum chamber into which pressurized freezing air by blown for admission into a laterally open plenum duct underlying the deck throughout its length. Such elongated plenum duct is tapered transversely beneath the deck for uniform distribution of pressurized freezing air to the discharge apertures in the deck by means of a transversely inclined duct-forming panel cooperating with the deck. On its upper side the panel forms the plenum duct and on its lower side the panel cooperates with a surrounding enclosure common to the helical turns of the conveyance deck to form a collecting chamber from which air is withdrawn by the combined freezing and pressurizing means for recirculation continuingly as the container or packages descend by increment progressively down the helical path of the deck. A partition with variable damper means separates the central plenum chamber and the surrounding collecting chamber and provides a variable bypass to regulate or vary the flow of air through such discharge apertures and maintain constant airflow through refrigerated evaporator coils so as to maintain efficient heat exchange operation thereof. With the comestibles packaged in the usual manner so as to afford air space within the packages for expansion of the comestibles upon freezing, this method of combined conveyance and freezing by use of the pressurized air flow greatly accelerates the freezing process and affects conveyance of the comestibles, appropriately retarded to maintain relative high-velocity flow of air sweeping me packages, without necessity for mechanical conveyance devices.

Abstract: ABSTRACT The invention relates to a controlled heating system for maintaining a predetermined or set temperature in a medium of small dimensions which may be a gas, liquid or solid.  A single element such as a power transistor functions as a heat transfer device for supplying heat to the medium and as a heat sensing device for sensing temperature changes in the medium which can be fed back and serve as control data for supplying make-up heat to maintain a predetermined temperature.  The transistor supplies heat via heat dissipation in its collector-emitter path and senses heat changes via its base-emitter voltage which varies in response to temperature changes in the medium.  The controlled heating may be applied to a valve assembly for a refrigeration plant of the kind used for controlling the flow of refrigerant from the evaporator to the compressor.  The closure member for the value unit is controlled directly or indirectly by a movable wall of an expansible chamber filled with a refrigerant medium having vapor and liquid phases.  The transistor serves as a heat transfer element and as a temperature responsive sensor element.

Abstract: Abstract of the Disclosure Bottle filling machines are known in which bottles travel in a circular path and, while doing so, are filled with liquid under pressure, e.g. beer, by individually associated filler mechanisms.          If, because of the pressure, a bottle explodes, glass fragments can adhere to the associated filler mechanism and it is important that these be removed, to keep glass from entering the next bottle coming in.  Resort has been made to using water sprays but heretofore such means have been relatively ineffective and, in some cases, very messy in operation.  The present invention provides apparatus which can thoroughly clean a filler mechanism in the event of an exploding bottle.          A broken bottle sensor is located between the infeed mechanism and outfeed mechanism on the bottle filling machine.  In the event of a broken bottle, the sensor provides a pulse to activate, for a predetermined period of time, a water spray assembly comprising a plurality of high pressure spray nozzles spaced apart along a portion of the path between the sensor and the outfeed mechanism.  The pulse also feeds logic means to record a data bit for each filler tube mechanism associated with a broken bottle, to track the location of the filler tube mechanisms as they move along the path, and to re-activate the spray assembly again for the predetermined period of time when an affected filler tube mechanism again reaches the broken bottle sensor.
