Abstract: Disclosed is a syringe assembly which greatly reduces the chances of an operator coming in contact with an infectious needle. The syringe assembly is initially provided with its needle retracted within its barrel, in a sterile and safe environment. When used, the needle is engaged by the plunger, and locked in place at the forward end of the syringe barrel. Before disposal, the needle is withdrawn back into the barrel, and the plunger is broken off. Thus, the disposed of syringe is incapable of being reused, and there is little or no danger of accidental punctures, because the needle is retained within the syringe barrel.

Abstract: An apparatus for preparing a semi-frozen confection of the present invention has a freezing cylinder for main ingredient of the semi-frozen confection, and a syrup refrigerating cylinder installed in the vicinity of both a semi-frozen confection dispensing conduit and the freezing cylinder. Accordingly, when preparing a semi-frozen confection composed of, e.g., ice cream and syrup to be served in a cone, rise in the temperature of the ice cream caused by the syrup may be restrained, thereby enabling the semi-frozen confection produced to retain its shape. The apparatus further has a microcomputer for controlling the rotating speed of at least one of the mixers respectively housed in the freezing cylinder and in the syrup refrigerating cylinder. This permits the proportion of, e.g., the ice cream and syrup composing the semi-frozen confection to be varied as desired.
