Abstract: An improved nozzle for beverage dispenser assures a high flow rate (for example, approximately 6 oz/sec or more), while maintaining a high quality beverage. An accumulator chamber reduces the turbulence of the incoming liquid to reduce carbonation loss. The nozzle converts high upstream liquid velocities to very low liquid velocities within the nozzle without an attendant high pressure loss across the nozzle. The nozzle is provided with a syrup accumulator chamber and a wide orifice syrup diverter which allow syrup to gently mix with a first portion of soda water substantially simultaneously during the dispense cycle and at substantially the same relative velocity. Thereafter the mixture of syrup and the first portion of soda water is mixed with a second portion of soda water.

Abstract: A fluid flow sensor comprises a housing having a fluid inlet and a fluid outlet, a measuring chamber in the housing connected at opposite ends to both the fluid inlet and the fluid outlet, a member in the chamber movable between opposite ends of the chamber, and a valve assembly for controlling fluid flow through the housing. The valve assembly is movable between a first position in which it cuts off one end of the chamber from the outlet so that fluid in that end of the chamber acts on the movable member to urge it to the other end of the chamber, and a second position in which it cuts off the other end of the chamber from the outlet so that the member is urged back in the opposite direction. The member oscillates back and forth at a rate proportional to the flow rate.

Abstract: A gas fired broiler having a plurality of burners adjacent to multiple conveyors with a shield on at least one of the burners in the area of one of the conveyors.

Abstract: A forced air convection oven for use by restaurants and delicatessens for cooking ribs and other meat products. Liquid smoke or other liquid flavoring agent is sucked from a container, is atomized and is sprayed into the cooking chamber of the oven to impart a desired flavor to the meat.

Abstract: A pair of snips comprising handle levers pivoted at one end and elongated shaped centrally pivoted blade cross-pivoted levers pivoted at their ends opposite their blades to said handle levers adjacent their end pivot, which blade levers have integrally formed therewith projections extending radially outwardly from their center cross pivot diametrically opposite the edges of said blades, which projections have contacting surfaces in substantially the same plane as the contacting edges of said blade forming rides for restricting the spreading of said blades axially of their cross pivot.

Abstract: The hearth of the furnace is indexed in such a manner that successive workpieces in a loading position are loaded in non-adjacent stations of the hearth during one revolution and are loaded in intervening stations during one or more subsequent revolutions. The method of loading and indexing the hearth enables a uniform temperature distribution to be more easily maintained in the furnace and provides flexibility in locating an unloading position relative to the loading position.

Abstract: A door is mounted on a carrier to move back and forth with the carrier between open and closed positions relative to a furnace doorway and to move inwardly relative to the carrier to seal the doorway. Bearing means engage the outer side of the carrier to support the carrier with rolling friction and to sustain the outward thrust which is imposed on the carrier when the door is moved inwardly to seal the doorway. The bearing means comprise a single spherical ball which is captivated in a cage to roll back and forth when the carrier is shifted and, at the same time, to spin universally about its own center.

Abstract: A pressure fryer having a vessel adapted to cook a food product within a bath of cooking oil. Means are provided for detecting the presence of water in the vessel and the bath and for automatically disabling the heater of the fryer if water is present in such quantity as to create a potentially unsafe condition.

Abstract: A pressure fryer having a vessel adapted to cook a food product within a bath of cooking oil. A cover seals the vessel in a pressure-tight condition and, as pressure builds up in the vessel, the cover automatically locks an opening-closing actuator to prevent the cover from being opened. When the pressure is relieved, the cover unlocks the actuator to permit opening of the cover.

Abstract: Workpieces are heat treated as they are advanced through and tumbled within a rotary retort. The retort is heated by electrical current which is inductively induced by coils disposed in surrounding relationship with the retort. A flared distributor on the exit end of the retort causes the workpiece to dribble continuously out of the retort.

Abstract: A food product is cooked under pressure and within a bath of hot cooking oil in a vessel when the vessel is sealed closed by a cover. The pressure in the vessel is controlled by an exhaust valve which must be located in an open position before the cover may be closed and sealed. As long as the exhaust valve is closed, it is not possible to open a drain valve and drain the oil from the vessel.

Abstract: An aqueous adhesive composition containing a graft copolymerized product of low amylose starch and acrylamide with rheological and remoistening adhesive properties suitable for coating low basis weight kraft paper on transfer roll coating equipment to make remoistenable sealing tapes. The desired properties of the adhesive composition are obtained by a controlled graft copolymerization together with a simultaneous gelatinization of the starch at temperatures below 210.degree. F. and with the essential addition of cupric or ferric ions before initiating the reaction. The resulting coatable adhesive has a comparatively low viscosity as required for transfer roll coating while retaining the improved adhesion properties of the acrylamide.

Means are provided for detecting the presence of water in the vessel and the bath and for automatically disabling the heater of the fryer if water is present in such quantity as to create a potentially unsafe condition.

Abstract: A temperature sensitive resistor is immersed in a bath of quench oil and is supplied with electrical power sufficient to keep the resistor at a predetermined and substantially constant temperature above the vaporization point of water. When water is present in the oil, the water is vaporized by the resistor with the vaporization acting to cool the resistor and lower its resistance value. A signal which varies as a function of the drop in the resistance value of the resistor is produced and causes an increase in the power supplied to the resistor so as to keep the resistor at its predetermined temperature. In addition, transient pulses in the signal are detected and an alarm signal is produced when there is sufficient water present in the oil bath to cause the time-average value of the pulses to exceed a predetermined threshold.

Abstract: Electrical resistance heating elements made of graphite and disposed in a ceramic tube are protected against breakage during shipment by cardboard inserts which are telescoped over the heating elements and into the tube. When the heating elements are first energized, the inserts burn away into harmless ash which falls to the bottom of the tube.

Abstract: Disclosed is a novel method for determining the degree of cure of polyester and epoxy resins which includes the steps of adding a catalyst, containing a pigment, to the resin; mixing the two components to provide a visually uniform distribution of the catalyst and pigment throughout the resin; and, depositing the mixture in a desired position for curing. The pigment can also be added directly to the resin rather than the catalyst. Additionally, in either alternative, at the completion of the curing the color imparted by the pigment has substantially disappeared from the cured product as though no pigment had been employed. Also disclosed is a novel benzoyl peroxide paste composition, for curing polyester resins, having a pigment the color of which substantially disappears from the cured product.

Abstract: Gas is circulated within the chamber of a heat treating furnace by a fan which is driven by an electric motor. The current drawn by the motor is detected and, when the current exceeds a predetermined magnitude, the density of the gas in the chamber is reduced to prevent an excessive load from being imposed on the motor. The density of the gas is reduced by shutting off the flow of gas to the chamber and by exhausting gas from the chamber.

Abstract: Graphite heating rods are disposed within a radiant tube which contains nitrogen under pressure to prevent oxidation of the rods. The pressure in the tube is sensed and nitrogen is admitted into or exhausted from the tube depending upon whether the pressure drops below or rises above a safe range. Only as much nitrogen is introduced into the tube as is necessary to replenish that which might be lost through normal leakage and thus only a comparatively small quantity of nitrogen is required to protect the graphite rods.

Abstract: More uniform heat treating of a work load is achieved by circulating the gas back and forth past the work with a pulsating reciprocating motion while the work is being heated.

Abstract: The hot flue gas expelled from a furnace is used to heat air which is supplied to the burners that fire the furnace. The heated air is delivered to each burner through its ceramic burner block rather than through its cast iron burner body so as to avoid the need of making the body out of expensive alloys capable of withstanding high temperatures.
