Title: Improvements in and relating to control devices for gas-heated apparatus
IPC: F23C99/00
Filed: 1936-10-22
Abstract: 463,777. Thermally-actuated valves. JUNKERS & CO., GES. Oct. 22, 1936, No. 28724. Convention date, Nov. 28,. 1935. [Class 135] A valve 13, controlling the supply of gas to the main burner 10 of a water heater and actuated by a bi-metallic thermostat 15 heated by an ignition burner 26, co-operates with a cut-off seating 16 and with a control seating 17, the burner 26 being connected by a passage 29 to a point between the two seatings. When the burner 26 is extinguished, valve 13 engages the seating 16 so as to cut-off the supply of gas to the burner 10. On lighting the burner 26, the valve 13 moves towards the seating 17 and so regulates the supply of gas to the main and ignition burners that the heating effect of the burner 10 is constant, irrespective of fluctuations in the pressure and heating value of the gas. The heating effect is adjusted by a valve 32 in the passage 29. As shown in Fig. 1, an auxiliary valve 12 in the gas supply pipe is controlled through a diaphragm 14 by the flow of water in the heater so that when water is not flowing the valve 12 is closed. A byepass 25 to the burner 26 is controlled by a valve 27 coupled to the valve 12 so that when the latter is closed the valve 27 is open. A manually-operated cock 30 is provided in the byepass 25, and a non-return valve 28 is provided in the passage 29. In a modification, a double-seated valve 42, Fig. 3, located in the byepass 25 is controlled by both valves 12 and 13. When the apparatus is inoperative, the valve 42 is in an intermediate position. On lighting the burner 26, valve 13 moves towards the seating 17 and in so doing acts on the valve 42 to cause the latter to throttle the supply to the burner 26. When water flows, valve 12 opens and causes valve 42 to close the byepass 25. In the form shown in Fig. 2, the thermostat 15 actuates the valve 13 through a spring 38. A rod 39 carried by a spring-loaded diaphragm 14<1>, operated by the flow of water, operates, preferably through a spring 40, to maintain valve 13 against the cut-off seating 16 when water is not flowing, the thermostat then serving merely to compress the spring 38. The diaphragm 14<1> also carries a valve 34 regulating the water supply.
Patent GB-1526463-A (GB)
Title: Apparatus for scanning an array of switches
IPC: H04M1/50
Filed: 1976-07-09
Abstract: 1526463 Synthesis of waveforms WESTERN ELECTRIC CO Inc 9 July 1976 [10 July 1975] 28761/76 Heading H3H [Also in Division G4] Apparatus for scanning a plurality of switches at intersections of a set of row circuits and a set of column circuits, provides a first signal to all the circuits of one set and provides a second signal in a recurring sequence to each circuit of the other set, and samples in a recurring sequence each circuit of said one set to detect the second signal coupled to it through an actuated one of the switches. Depression of any of a matrix of keys lowers a magnet attached to the key to attract a movable plate of a capacitor associated with the key towards a stationary plate of the capacitor. The movable plates are connected in columns and the stationary plates are connected in rows. The columns are scanned in turn by enabling respective NANDs which also receive a clock pulse train, each NAND feeding its respective column. The clock pulse train is also applied to all the rows simultaneously via capacitive coupling from guard circuits. The row outputs are gated in turn via a storage capacitor to an integrating capacitor and if a threshold is reached, a flip-flop is set. This indicates the presence of a phase-reversal indicative of depression of a key. The flip-flop causes latching of row and column counts representing the position in the matrix of the depressed key. The latched information, by means of shift registers and logic, controls counting (number counted before reset) in further shift registers to control the frequencies of two groups of yes-no waveforms produced. These waveforms are then combined in NOR gates feeding a parallel resistor network to produce a dual-frequency analogue waveform for telephone dialling. One of the frequencies was selected by the row of the matrix and the other by the column. The NOR gates are disabled by a "single key logic" to inhibit output if more than one output is produced from the flip-flop in a scanning cycle i.e. more than one key depressed. Any output from the flip-flop sets a first flip-flop in this "single key logic" circuit to set a second flip-flop and enable a third flip-flop to be set by any further output to reset the second flip-flop.

Abstract: 996,159. Tyre retreading apparatus. SUPER MOLD CORPORATION OF CALIFORNIA. July 26, 1962, No. 28765/62. Heading B5A. In a tyre retreading apparatus comprising a bottom matrix carrying mould half 20, and an upper mould half 22, pivotable to an open position by a cylinder and piston device 40, the diameter of the tyre C is reduced to facilitate correct positioning within the mould halves by bead engaging wheels 120, 130. The lower wheel 120 is fixed to the upper end of a hollow shaft 86 which is raised and lowered by a piston 90 reciprocable in a cylinder 74 depending from an adapter plate 70, fixed to frame F. The upper wheel 130 is detachably mounted upon the upper end of a rod 124 which is raised and lowered, relative to, or in unison with, shaft 86, by a piston 111, reciprocable within a cylinder 106 carried by the lower end of shaft 86. In operation the tyre is positioned on the lower wheel and the upper wheel positioned above it on rod 124, and then lowered so as to compress and reduce the diameter of the tyre. Both wheels are then lowered together to locate the tyre to the lower mould, the upper mould half then being lowered and the curing performed using a conventional curing bag. After curing the tyre is freed from the mould matrix by first moving the lower wheel toward the upper and then vice versa, after which the mould is reopened, both wheels raised, the upper wheel disengaged and removed, and the retreaded tyre removed.

Abstract: 559,513. Wireless receiving and transmitting apparatus. AKTIEBOLAGET ELEKTROD. Oct. 26, 1939 No. 28768. Convention date, Nov. 15, 1938. [Classes 39 (i) and 40 (v)] A glow lamp 5, Fig. 1, is used to indicate both the state of the anode battery 2 and whether the main switch 7 is closed. In the case of a receiver the lamp 5 is designed to extinguish at 90 volts when used with 120 volt battery. In the case of a portable transmitter with a 400 volt battery, the lamp does not extinguish till 100 volts is reached so as to allow for the large momentary voltage drop during keying. The glow lamp for low voltages can have a cathode activated by a deposit of barium oxide and a filling of neon and argon at about 20 mm of mercury. For high voltages with a big difference between striking and extinguishing voltages an insulated grid 17, Fig. 4, is used, with a mesh of 2 mm, and a filling of argon at 15 mm of mercury. A reflecting layer 18 connected to the positive electrode may also be used.

A gas burner valve for a liquid-fuelled cigarette lighter comprises an open-ended cylindrical bore 2 and a valve member axially movable in the bore 2, and having at its inner end a resilient shut-off disc 12 adapted to seal an aperture 5 in the base of the bore 2, and an annulus 13 of plastic foam arranged under pressure between a conical base portion 3 of the bore 2 and the part conical surface 10 of the valve member. The valve member is sealed in the bore 2 by an 0-ring 9 accommodated in a groove 8 in the valve member. The aperture 5 is surrounded by a raised seat 6 and a well 4 below the annulus 13. The resilient disc 12 is biased against the seat 6 by the forked end 16 of a pivoted plastic control device 17, Fig. 2 (not shown), which engages a groove 15 of the valve member and has an integral projection 22, acting as a spring and located in a slot 23 in the lighter casing. The downward movement of the fingerpiece 21 of the control device 17 separates the seat 6 and the resilient disc 12 and is limited by a screwed stud 24 in the lighter casing. The bore 2 is formed in a recess in the wall of the fuel reservoir or may be a separate part screwed into the reservoir wall.
