Title: Improvements in or relating to dry pipe valves for fireextinguishing sprinkler systems
IPC: A62C35/64
Filed: 1925-07-17
Abstract: 241,142. Lewis, L. M. July 17, 1925. Sprinklers, automatic.-A dry-pipe valve of the kind in which an air valve 15 is arranged at an angle to a water valve 30 of smaller size is provided with means to prevent any lateral sliding movement of the water valve when it is forced against its seat. The air valve is rigidly connected to a link 22 pivoted at 28 in the upper chamber 5 and engages a rubber seating 17 on a ring 12. A link 35 is pivoted at 36 to the air valve and at 45 to the water valve, and a link 44 pivoted in the lower chamber 6 at 42 is also pivoted on the pin 45. When the valve 30 is moving towards its seating 32 the link 44 constrains it to move in a path substantially normal to the plane of its seating 32 and prevents lateral sliding movement. When the air and water valves are raised the link 44 engages the water valve and turns it to a vertical position so that it does not impede the flow of water. A projection 75 on the link 35 assists in keeping it vertical. The air valve in closed position holds open a drip valve 65 by means of a finger 67. Removable closures 49, 50 give access to the valve casing 1, and the closure 50 carries a resilient buffer 53.

Class 135 [Also in Group XIII] A float t in the transfer chamber k of a refrigerating apparatus (see Group XIII) actuates valves m, o which alternately put the transfer chamber into communication with the condenser through a pipe e and with the top of the absorber g through a pipe n. The float t is guided by a stem t<SP>1</SP> and actuates a link u by a pin u<SP>2</SP> riding in a slot u<SP>3</SP> to permit lost motion. The link u is connected to a pair of oppositely extending U- shaped lever arms v<SP>1</SP>, v<SP>2</SP> pivoted at w and connected by a toggle spring x to give a snap action when thrust and pulled by the link u. When the transfer chamber k is filled with strong liquor the link u raises the lever arm v<SP>1</SP> to snap up the lever arm v<SP>2</SP>, open the valve m and allow the valve o to close. The pressures in the transfer chamber and the generator are thus equalised and the strong liquor flows by gravity to the generator. When the float t reaches the bottom of its stroke the valves are reversed, equalising the pressure in the transfer chamber and the absorber, so that strong liquor at the bottom of the absorber can flow through pipe p to the transfer chamber.

Class 40 (8) A variable electric attenuator in which, over a range of frequencies, the attenuation is independent of frequency, comprises an input circuit which is mainly inductive over the range, and a circuit connected to output which is mainly resistive over the range, there being variable mutual inductive coupling between the two circuits. As shown, the input circuit through the coils 4 and 5 is completed by the wire 3 passing through the walls of the circular metal tube 1, from which it is insulated, and the closed end 2 of which is earthed. Sliding inside the tube 1 is a further metal tube 8, inside which lies a length of coaxial cable 9 the inner and outer conductors 14 and 15 of which constitute the output terminals of the attenuator. The end 12 of the cable 9 has a cartridge type resistor 13, connected between the inner and outer conductors, having a resistance R equal to the characteristic impedance of the cable 9. The mutual inductance coupling between wire 3 and resistor 13 is varied by sliding the tube 8 of the coaxial tube 9 which is connected to it, relative to the tube 1. The reactance of the self-inductance of the connection through resistor 13 across the end 12 of the cable 9 should be less than R/7 over the range of frequencies. The coils 4 and 5 may be the inductance of a resonant circuit of an oscillator, in which case a capacity is connected across terminals 6, 7. A Faraday screen may be provided between wire 3 and resistor 13. Specific dimensions aregiven for an attenuator to be used in the range 50 to 120 megacycles per second.

[Also in Division H3] In an oscillator including a tuned circuit associated with an amplifier, the amplitude of oscillations in the tuned circuit is maintained constant by a control impedance element which is connected in a signal path between the input and output terminals of the amplifier and which is controlled by an output-dependent control signal derived from means separate from the said signal path. As shown, an oscillator 1 comprises a transistor 10, a transformer 14, a positive feedback path including a crystal 18 and a negative feedback path including an indirectly heated thermistor 24. The output from the oscillator 1 is amplified by a buffer amplifier 2 including a transistor 50 and a transformer 54 giving an output on leads 28, 57, and the amplitude of this output is maintained constant by automatically controlling the impedance of thermistor 24 in dependence upon output variations; the signal to effect this control is derived from the collector of transistor 50 by way of a rectifier circuit 3 and a D.C. amplifier 4 the output from which is applied to the heater 30 of thermistor 24, whereby the impedance of the thermistor is automatically varied in a sense to correct variations in the output amplitude. The thermistor may be replaced by a suitably connected thermionic or semi-conductor diode, by a voltage sensitive capacitor, by an inductor, or by a light sensitive element responsive to the light from a filament lamp energized from the oscillator output. Thermionic devices may replace the semi-conductor devices in the stages 1, 2, 3 and 4.

In a modification, the trap is formed by a pair of rollers, one or both of which are eccentrically mounted so that the gap between the rollers may be adjusted by movement of a rack engaging gear-wheels on the axles of the rollers. In the form shown in Fig. 6, the traps are formed by parallel plates x<3>, x<4> mounted on a conveyer 33 and having diverging jaws x<1>, x<2>; cops of a predetermined diameter fall between the plates x<3>, x' and are carried by the conveyer to the end of the machine where they are discharged into a box 10, while cops above the predetermined diameter are carried forward by the jaws x<1>, x<2> and engaged by an inclined shoot 43 by which they are delivered into a box 32. In a modification, the traps are formed with additional diverging jaws so as to sort the cops into three or more groups. In the form shown in Fig. 9, the traps are formed by elastic jaws 65, 66, the jaw 65 being fixed to the conveyer 33 and the jaw being pivoted thereto so that it can be opened against the action of a spring; cops of a diameter above a predetermined diameter are gripped tightly by the jaws and carried by the conveyer to a position above the box 32 where an abutment 68 engages a finger 67 on the jaw 66 and opens it to release the cop while the cops of predetermined diameter-loosely held in the trap-are discharged into a box 10. In a modification, a pair of spaced abutments engage the ends of the cops of larger diameter and force them out of the jaws as they arrive over the box 32.
