Title: Improved water level alarm and valve movement indicator for steam boilers and the like
IPC: F22B37/42
Filed: 1924-11-05
Abstract: 246,920. Gordon & Co., Ltd., J., and Armstrong, C. H. Nov. 5, 1924. Alarms, high and low water. - An indicator b deriving its motion from that of the feed-water valve of a steam generator or the like, carries a contact d positioned between its pivoted and free ends adapted to slide along a curved contact e, and also carries contacts f, f<1> at its free end adapted to complete an electric circuit at the high or low water level through contacts g, g<1> respectively to cause visible and audible alarms to operate. The pointer is influenced by means of an auxiliary lever p having a common pivot c and joined to the lever of the feed water valve, or of a thermostat which regulates it by a connector (not shown). A scale s is provided so that the pointer may indicate intermediate positions of the water level.

Filed: 1973-06-04
Abstract: 1438192 Back-up protective systems WESTINGHOUSE ELECTRIC CORP 4 June 1973 [2 June 1972] 26449/73 Heading H2K A back-up protective system has a principal circuit breaker 4 which will normally be tripped, due to a fault at F, by means of a fault detector fed from a current transformer 18 and voltage transformer 16. The detector also starts a timer 26 which is controlled by a hold device 28 to ensure completion of the timing operation. After the preset time the timer operates a switching device 24 to connect a sensing device 20 to a resistor 22 in the circuit of the current transformer 18. If fault current is still flowing in the feeder 1 the sensing device will trip the back-up circuit-breakers 10, 12. Alternatively the resistor 22 may be omitted if the device 24 includes current energized transducers in a three phase arrangement in which the timer 26 removes a current shunt across 24.

Sliding-weight apparatus. - In a weighing- apparatus of the type, employing a steelyard the sliding poise is provided with an operating member so arranged that a weighing can only be effected when the poise is located at a graduation or in a positioning notch. The steelyard 4 is mounted on a fulcrum 3 and carries a poise 7 sliding on a notched bar 5. Beneath the steelyard is a hand-operated shaft 13 capable of sliding horizontally along a slot 18 but capable of rotation only at the enlargements 20. With the shaft in the position shown, a cam 23 thereon supports a parallel-motion bar 24 which holds the steelyard in an horizontal position, and a second cam 16 supports the poise 7 with its nib 9 clear of the notches 6. A projection 17 on the cam 16 is situated between pins 11, 12 on the poise. To adjust the poise the shaft 13 is moved along the slot 18 to one of the enlargements 20 and is then rotated through 90‹, thus allowing the bar 24 to release the steelyard, removing the cam 16 from beneath the poise, and by means of the projection 17, positioning the nib 9 in the notch. A cable 31 connected to the shaft 13 actuates an indicator 30 in usual manner.

Abstract: 945,101. Semi-conductor devices. NIPPON ELECTRIC CO. Ltd. July 24, 1961 [Aug. 25, 1960], No. 26767/61. Heading H1K. A tunnel diode and a Zener diode are formed on a single semi-conductor crystal wafer so as to be in series and in back-to-back relationship with each other. The characteristic of such a device is shown in Fig. 5 and it is stated that the negative resistance range c occurs over a higher and narrower voltage range than for a single tunnel diode and that the device has a very high forward resistance in the voltage range a below the negative resistance range. It is assumed that the reverse resistance of the Zener diode takes preference over the range a, that its Zener breakdown governs range b, and that the tunnel diode mechanism is operative over ranges c and d. An N-type germanium crystal 11 (specific resistance less than 0.05 ohm. cm.) has alloyed thereto a ball of indium containing up to 5% of arsenic to form an N+ layer 12. Part of the surface of layer 12 and crystal 11 is then etched using hydrochloric acid and balls of indium containing up to 0.5% of gallium are alloyed to the etched surfaces to form a P+ N+ junction 13 and a PN junction 14. In an alternative construction (Fig. 3, not shown), a P-type semi-conductor wafer is used, the PN junction then taking the form PN+.

Abstract: 519,533. Closets. GROENIGER, W. C. Sept. 14, 1938. No. 26845. Convention date, Sept. 25, 1937. [Class 26] A water closet comprises a flush rim associated with the seat for the discharge of flushing water beneath the seat, so as to scour the upper walls of the interior of the bowl, a combined seat hinge, and a flush rim supply valve control mechanism so arranged that the valve is opened when the seat is lowered and closed when the seat is raised: The flush rim, with its series of discharge apertures, may be incorporated in the seat structure, or may be independent thereof, each structure being pivoted on the same hinges and swingable independently of the others. In the form shown, flushing water from the chamber 12 passes through the ports 35 of the pair of inlet arms 34, through the ports 33, 31 of the arm 34 and sleeve 30 respectively, and so to the holes 23 in the channel 22 formed in the seat. The seat hinges on the ends 28 of the arms 34 so that as the seat is raised the two ports 31, 33 move out of register and the water flow to the seat is prevented, the water passing to a channel in the closet bowl and to an orifice 20 at the back of the bowl. In a modification the arms 34 may be connected at the side of the flushing water reservoir 12 instead of the front. The lower edge of the orifice 20 is above the overflow level of the bowl, as are also the apertures 23 in the flush rim, so that back siphonage into the water supply pipes is prevented. Specifications 518,144 and 519,531 are referred to.
