Title: Continuous disintegration of microorganic cellular structure - esp. of yeasts, by gas saturation and constriction (CS 29.7.77)
Inventor: RAKITIN V J
IPC: B02C19/00
Filed: 1976-08-13
Abstract: The micro-organic cells of yeasts, bacteria and fungi are disintegrated in a continuous process, by constricting the watery suspension of cells to bring about their destruction. The aq. suspension of the cells of micro-organisms is satd. with a gas at a controlled press. so that at least some of the gas is dissolved. The suspension is maintained for a period at this saturation press. so that the distribution throughout is uniform, and the suspension is then passed through the battery of disintegrators. The passage through narrow slits in these devices brings about an abrupt fall in press. so that the internal press. of the cells bursts out destroying their sheaths. The plant can be used for obtaining disintegration from the cells which improve digestion and cut out the stages of plasmolysis, as well as the sepg. the intracellular biopolymers such as albumen, ferments, nucleic acids. A hydro-extruder may be used for this disintegration. The loads are detented in stages and the capacity of the plant is 10m3/h. The plant requires high investment costs and has a high energy consumption. With single stage detenting the disintegration is not satisfactory. Disintegration is also carried out in ball mills with corundum, glass or other balls 0.5-0.75 mm dia. The prodn. of this plant is very low and energy requirements are very high. A further process uses two thick-walled vessels in tandem and gas press. of 100-120 atm. This also has a complicated design and a low output. These difficulties are overcome by a disintegrator battery.

Title: Hot water storage tank flow system - has ball valve and burner controller operated by large volumes with small hole for small volumes
Inventor: CHARRON JEAN-CLAUDE
IPC: F24D3/08
Filed: 1977-01-28
Abstract: The hot water supply system has a hot water tank (1) with a heating coil (3) around it, with connection (4, 5) for a supply from the boiler. The discharge line (6) starts from an inverted U-shaped tube (6a) housing an temperature sensing element (10) controlling a relay unit (11) which operates the boiler burner. The end is controlled by a ball (8) inside a cage (7). As soon as the temperature of the water in the tank reaches a required upper level, the element (10) shuts off the burner. When a small quantity of water is drawn off, the flow is insufficient to operate the device or pull the valve from its seat (6b), but instead flows through a small hole (9) in the discharge line (6). A larger flow draws the ball valve from its seat and also operates the burner controller (10).
