Patent DE-3063915-D1 (DE)
Title: Injection mould with high capacity sprue bushing
Inventor: SCHULTE WOLFGANG
IPC: B29C45/77
Filed: 1980-11-15
Granted: 1983-07-28
Abstract: Apparatus for injection moulding thermoplastic material is disclosed wherein a heavy-duty sprue bush is heated along a substantial portion of its length to keep the thermoplastic material from solidifying during interruptions in the moulding cycle. The apparatus provides for minimal contact between the heated sprue bush and the moulding die to prevent heat transfer between them. This is achieved by maintaining an air gap between the bush and the die except at points where the thermoplastic material passes into the moulding cavity. Sprue runners oriented generally parallel to the mould joint line are aligned with cavity injection openings which are similarly oriented. These injection openings pass through a thin wall of the mould that extends generally perpendicularly to the joint line such that when the moulds are open, the sprue is cleanly severed from the moulded article.

Title: Apparatus and process for low-pressure casting
Inventor: LUTHY HANS
IPC: B22D47/00
Filed: 1981-10-26
Granted: 1985-03-28
Abstract: With low-pressure or die-casting methods there frequently occur leaks during the transfer of the molten metal from the metal containing basin or vessel to the mold. These leaks often lead to serious accidents and related operating interruptions. According to the invention these problems are solved by a casting method, wherein all movements of the mold occur in a vertical plane. With a preferred embodiment of apparatus for the performance of the method the mold is placed in a positive or form-locking manner with its casting or pour opening upon the casting hole of the metal containing vessel or basin and pressed against the latter in a fluidtight fashion by means of a pneumatic lifting cylinder. This affords the advantage of a simple connection of the mold with the basin and without requiring a coupling mechanism, and, additionally, the heating of the riser or up tube and/or immersion tube can be omitted, which otherwise conventionally was performed by gas heating.

Title: Method of pasteurizing alimentary products in machines provided with gas-compression refrigerating circuits
Inventor: MANFRONI EZIO
IPC: A23G9/30
Filed: 1982-02-04
Granted: 1987-02-05
Abstract: The circuit of a gas-compression refrigerating unit in ice-cream making machines and/or ice-cream mixture pasteurizing machines has inserted therein a by-pass circuit controlled by one or more switching valves. During the cycle of pasteurization and/or sterilization of the ice-cream mixture and of the elements of the machine contacting said mixture (either liquid or frozen), the hot refrigerant gas coming from the compressor is diverted through the evaporator (by-passing both the condenser and expansion valve) so as to heat to a sterilization temperature all the elements of the apparatus which usually are cooled by said evaporator. On completion of this pasteurization and/or sterilization cycle, said by-pass circuit in shut off and the refrigeration cycle is resumed by switching said valves, whereby the fluid refrigerant is circulated from the compressor to the condenser and expansion valves into the evaporator so as to refrigerate the elements that are in heat exchange relationship with said evaporator.
