Title: An improved measuring tea caddy
IPC: G01F11/24
Filed: 1922-05-18
Abstract: 202,705. McLean, N. W., and Kyle, W. A. May 18, 1922. Moving-chamber apparatus for granular materials. - A tea-measuring caddy comprises a container A with a tapering bottom end within which is rotatably mounted a closelyfitting sphere D fixed to a spindle E but to form a handle E<1>. The sphere has a depression F to contain the measured quantity and a weight G may be fitted so that the depression will normally be turned downwards. A cover C enables the caddy to be filled and a conical member H pressed upon the sphere by springs J prevents tea jamming between the sphere and the spout. In a modification, the spout and sphere are separate from the container and mounted so that the container, in the form of a bottle, can be inverted over the spout and rest upon the sphere. The apparatus is adapted to be fixed against a wall and the bottle may be so mounted that it swings away from the spout when inverted, for convenience in refilling.

Abstract: 514,800. Automatic regulation. SIEMENS & HALSKE AKT.-GES. May 16, 1938. No. 14605. Convention date, May 15, 1937. [Class 38 (iv)] In an arrangement for deriving constant voltage from a fluctuating, voltage supply in which the output voltage Ua is obtained from an intermediate tapping of an arrangement, e.g., resistances 1, 4, supplied from the input voltage U, and from the junction between two resistances 2, 3 having different temperature coefficients supplied by the input voltage, the temperature co-efficients and values of the resistances are such that the curve of output current Ja through a constant impedance load 7, against input voltage has two maxima of substantially equal value. The curve between these values runs parallel to the abscissa axis. The resistance 2 may be formed by a metal filament lamp and the resistances 1 and 4 may be equal and similar to resistances 2 and 3 respectively, of which resistance 3 has no temperature coefficient. In a modification, Fig. 4, the input voltage is connected across a potential divider 8, 9 and the output circuit 7 is connected between the intermediate point of the divider and the junction of resistances 10 and 11 of different temperature co-efficients which are connected in series across the supply. The resistances are dimensioned as above stated. The supply may be A.C. or D.C. and the potential divider may be replaced by a tapped battery which forms the source as well as the divider. Thus a tapped dry battery may be arranged to give a constant voltage output throughout its-life. Values of the circuit constants are given in the Specification.

Refrigerating, absorption machines for.-Machines of the pivotally-mounted self-acting kind are provided with means for returning the liquor remaining in the evaporator from the previous evaporating period to the absorber during the tilting movement at the end of the next generating period. In the generating position, the liquor in the absorber 1, Fig. 1, is evaporated by an electric heater 2 and passes through a pipe 3 and liquid trap 6, which communicates through the pipe 17 with the absorber, to the condensers 9 from which the condensate flows into the uppermost of two evaporators 11, 12.
