Abstract: A protective circuit capable of preventing error voltage access, comprising a first unidirectional conduction element, a triode control circuit, a first triode, a first capacitor, a Darlington transistor, a first resistor, a second resistor, and a relay. A contact of the relay is connected in series between an input end and an output end. The first unidirectional conduction element has a first end connected to the input end and a second end that is connected to a first end of each of the first resistor, the first triode, the first capacitor, and the Darlington transistor, respectively. The triode control circuit is connected to a second end of the first resistor and a controlled end of the first triode, respectively, and a second end of the Darlington transistor is connected to a controlled end of the relay. According to the present invention, the input end can be disconnected from the output end when an error voltage is input.

Abstract: A process for producing frozen confectionery products, the process comprising: providing a source of a frozen confection to a chamber of a nozzle, the nozzle comprising an extrusion plate, wherein the extrusion plate defines one or more apertures in fluid communication with the chamber; wherein the apertures have a width of from 1 to 5 mm and a length of at least 10 mm; a first extrusion step of extruding the frozen confection from the chamber of the nozzle through the apertures of the extrusion plate, to produce extruded frozen confection having a direction of extrusion relative to the extrusion plate, the extrusion being carried out whilst the nozzle has a direction of movement having a component of movement in a direction parallel to the direction of extrusion wherein the component of movement is zero or in the same direction as the direction of extrusion; and followed by a second extrusion step of moving the nozzle with a direction of movement having a component of movement in a direction parallel to the

Abstract: A gas cylinder safety purge and anchor system features a gas cylinder with a plurality of cylinder apertures located around a neck outside periphery. The system features a cylindrical purge deflector with a plurality of deflector apertures located on a internal deflector cap component wall that align with the cylinder apertures when the purge deflector is positioned on the neck. The system features a valve on the cylinder. The system features an anchor assembly having a linear outer tube and a linear inner shaft located in the outer tube. In a first position, a first anchor projection, a second anchor projection, a third anchor projection, and a fourth anchor projection are each located perpendicularly with respect to the outer tube. In a second position, the first anchor projection, the second anchor projection, the third anchor projection, and the fourth anchor projection are each retracted.
