Inventor: WALLER CLIVE GREGORY
IPC: F25B49/00
Filed: 1991-10-03
Abstract: PCT No. PCT/AU91/00386 Sec. 371 Date Feb. 19, 1993 Sec. 102(e) Date Feb. 19, 1993 PCT Filed Aug. 23, 1991 PCT Pub. No. WO92/03718 PCT Pub. Date Mar. 5, 1992.A sensor (1) is provided for sensing the entrainment of a fluid of low specific gravity in a fluid of higher specific gravity, particularly the entrainment of refrigerant gas in refrigerant liquid. The sensor (1) is typically installed into a higher pressure liquid supply line (24) of a refrigeration system (26). The sensor (1) has a differential float (16) including a float member (54) pivoted about a pivot (56) in a chamber (14) coupled to the supply line (24). The float member (54) has a specific gravity greater than the specific gravity of both of the fluids in which it operates. However, the location of the pivot (56) intermediate of the length of the float member (54) gives a net specific gravity for the differential float (16) which is less than the specific gravity of one of the fluids. Hence, the differential float (16) can withstand a high pressure operation, say at 2MPa, and can operate as a float for detecting the presence or absence of the fluid of lower specific gravity in the fluid of high specific gravity. The differential float (16) can also be used as gauge snubber (20) or to replace refrigerant capillary control tubes.

IPC: A23L29/269
Filed: 1991-10-17
Abstract: Yeast refuse having a solids content not exceeding 20% by weight is digested with a food grade alkaline salt such as sodium bicarbonate, whole cells are separated from the extracted refuse so as to produce a material rich in disrupted cell walls which is then treated with an alkaline extraction agent and bleached either before or after the separation step, followed by lowering the pH of said bleached material using a food grade acid such as dilute hydrochloric acid. The product comprises a yeast beta-glucan which is substantially free of yeast cells, and which predominantly comprises a multiplicity of yeast ghosts or shells comprising substantially uncollapsed yeast cell walls. The yeast ghosts or shells contain a substantially lower quantity of yeast cell contents relative to the whole cells of the yeast refuse.

Abstract: A switch controller for a dynamic switch (10) responds to commands from a using system to provide control signals to the dynamic switch (10) which causes the switch to establish and breakdown paths between sources and destinations in the using system. The controller includes a plurality of command registers which are temporarily assigned to a command source for receiving command signals, decoding said signals and providing control signals to the switch for establishing or breaking down a switch path. The controller may if desired provide an echo to a selected destination so that proper execution of commands may be ascertained. After the commands are completed the control register is released for reassignment to another command source while an established switch path remains intact. Thus, commands may be received from any source for controlling the switch.
