Title: Valve for hydraulic apparatus - has conical seating portion and special profile to control flow on opening
IPC: F16K1/34
Filed: 1975-04-24
Abstract: The valve is closed against a conical seating by a spring, and thus prevents flow from an inlet to an outlet. The valve is especially profiled at the valve seat and has a first conical seating bearing against the valve seat, a short cylindrical portion, to allow grinding in of the valve, followed by a second larger diameter conically diverging portion which with a third conically converging portion together define a sharp line. On opening the valve under the influence of e.g. a magnetic actuator, the lip throttles the flow past the valve and changes the pressure distribution so that there is no tendency, as with existing valves, for the valve to bang shut again, thus damaging the valve seat. The arrangement allows smaller magnetic actuators to be used.

Title: High capacity yogurt-making appts. - with insulated base and cover to maintain constant temp. during fermentation
IPC: A23C9/12
Filed: 1977-04-05
Abstract: Family yogurt making appts., with a high capacity, consists of a well-insulated container, mounted on a base with heating element, in which the optimum temp. can be maintained throughout fermentation. The base, with its heating element and thermostat, supports a circular bell-shaped cover; this can be adjusted in height to suit the number of recipients for the yogurt by means of the vertical walls and the ball catches which engage in depressions at different heights in the cover. The drawing shows the latter in the position when only the principal recipient is in use. The inner recipient has a capacity of three litres and replaces a number of small containers used hitherto; the surface area/capacity ratio is thus considerably reduced and the heat losses are diminished in the same proportion. The temp. of the milk can more easily be maintained at the proper level during the whole of the fermentation period. The single container in the well-insulated cover economises in the labour for filling and seeding the larger number of small vessels previously used. Better temp. control is also attained by the redn. in the surface area of the container as compared with its capacity.
