Abstract: 540,791. Hinges. MIKETTA, C. A. April 20, 1940, No. 7169. [Class 65 (ii)] [Also in Group I] A water closet having a hinged seat and cover, a water supply line, and a flushing valve is provided with a member movable under the influence of the water supply and connected to the seat and cover, so as to permit the seat or cover or both to close when the pressure in the water supply line is reduced by the opening of the flushing valve. The movable member comprises a device 10 connected by a pipe 11 to the supply pipe 4 connected to a cistern 5 provided with a flushing handle 6. The device 10 comprises a housing separated by a partition 11<1>, Fig. 2, to form cylinders in which more plungers 12, 13 the lower ends of which are provided with cup leathers 14 held in place by screws 15. Mounted in the upper part of the device 10 are shafts 17, 18 in the form of hollow tubes, the shaft 18 being rotatably mounted in the shaft 17, and terminating at 18<1>. The shaft 17 extending through bearings 19, 20 formed in the upper ends of bolt 29, 22 extending through the bowl. The cover 3 is connected to the shaft 17 by the bracket 27 and to the shaft 18 by the bracket 27<1>, and the seat 2 to the shaft 17 by a bracket 28<1> and to the shaft 18 by a bracket 28. Cams 30, 31 provided with curved faces 32, flat faces 33 and end flat faces 34 are mounted on the shafts 17, 18, the latter shaft terminating within the device at about its mid-point. To place the plungers 12, 13 in the operative position, a handle 36 extends through the shaft 17 being provided with a pin 37 which extends through a slot 38 in the shaft. The end of the shaft 18 is notched at 39, the pin 37 sufficiently long to engage the edges of the notch. With the plungers 12, 13 in the position shown in Fig. 2, the handle 36 is rotated and by means of the pin 37 partially rotates the shaft 17. The cam 30 being rotated slightly into the position shown by the dotted lines in Fig. 4 and the pressure of water from the supply line 4 and the conduit 11 causes the plunger 13 to move upwardly thus raising the cover 3. If it is also desired to raise the seat 2, the handle 36 is rotated a little more, thus causing the pin 37 to engage the notch 39 and thus partly rotate the shaft 17 to operate the cam 31 and thus turn the shaft 18 to raise the seat. As soon as the flushing valve 6 is actuated, a reduction in pressure in the conduit 11, due to the flow of water to the bowl 1, as well as the space between the plungers 12, 13 is caused, springs 43, 44 tend to return the cams 30, 31 to their original positions. The weight of the cover and seat then rotate the shafts 17, 18, rotate the cams 30, 31, and depress the plungers 12, 13. When the cams return to their original position, Fig. 4, the faces 34 contact the plungers and hold the seat and cover in the closed position. The pipe 11 is screwed into a part 61, Fig. 9, by means of a nut 65, the part 61 being provided with a flared opening.

Filed: 1922-12-01
Abstract: 206,386. British Thomson - Houston Co., Ltd., (Compagnie Franþaise Thomson- Houston). Dec. 1, 1922. Thermal switches; partly electromagnetic.-For the protection of motors and apparatus against overload a pair of bimetallic strips 5, 6 within an enclosure 1 and carrying the main current serve, when the overload has existed long enough as determined by the variable effective length of the current path through the strips, to distort the strips and withdraw a spring member 9 which carries the armature 11 away from contacting engagement with the poles of a permanent magnet 12, thereby producing a quick-break action. The member 9 is connected to one terminal of the control circuit of the circuit breaker and the connector 13 in contact with the magnet with the other terminal so that, when the control circuit is broken, the circuit-breaker is opened. Instead of direct armature-to-magnet contact, ordinary contacts may be mounted on these parts. Adjustment for current and time is effected by moving the adjustable bridge-piece 7 which alters the effective length of bimetallic strip in the motor circuit.. The rate of heating and cooling of the thermal device is less than that of the machine or apparatus to be protected.

Abstract: 737,646. Radio receiving circuits. TELEFUNKEN GES., [formerly TELEFUNKEN GES FUR DRAHTLOSE TELEGRAPHIE]. Nov. 30, 1953 [Nov. 28, 1952], No. 33128/53. Class 40 (5). In a superheterodyne receiver for frequencymodulated signals, comprising a radio-frequency stage V, an additive mixer M, which, as shown, is of the self-oscillatory type, and a limiting stage (not shown), delayed automatic gain control is applied to the radio-frequency stage V. The automatic gain control prevents overloading of the mixer M on strong signals, and is derived from grid current in an intermediate frequency-amplifier Z, by way of resistors R1, R2, R3 and smoothing condenser C1. The control is delayed-by applying negative bias to the valve Z if necessary-so that it does not come into operation until the limiter is fully effective. In a receiver which can be switched to receive amplitude modulated signals, the resistor R2 is returned to an automatic gain control diode, Fig. 2 (not shown), which then provides a control voltage for both the stages V, Z.
