Title: Improvements in or relating to electrically heated hot-water reservoirs
IPC: F24H9/20
Filed: 1935-08-06
Abstract: 461,134. Automatic control systems. STIEBEL, T. Aug. 6, 1935, No. 22180. [Class 38 (iv)] Temperatures.-In an electrically heated water reservoir of the overflow type, the current supply to two or more internal heat ing elements c, d, Fig 1, arranged at differ ent levels is so con trolled by a tilting mercury switch g operated by a therma element e extending through the reservoir that first the circuit is closed through the lower element c until the water is heated to a predetermined temperature of, say, 85 C. and then the circuit is opened through the element and closed through the upper element d, which heats the water to a predetermined temperature of, say, 100 C., the circuit being finally opened before the whole of the water has been heated to the higher predetermined temperature. The current may be controlled by a five-pole mercury switch, Fig. 2, having a hand-operated switch n between the second and fourth poles. When the switch n is open, the water is heated first by the upper element then by the lower element to a lower predetermined temperature. When the switch is closed, the water is further heated first by the lower element then by the upper element to a higher predetermined temperature, the circuit being finally closed before the whole of the water reaches the higher temperature.

Title: Improvements in or relating to thermionic valve amplifiers
IPC: H03G5/26
Filed: 1935-08-07
Abstract: 460,915. Valve amplifying circuits. PERCIVAL, W. S. Aug. 7, 1935, No. 22342. [Class 40 (v)] Movement of the slider 11 on the potential divider 8, 9 varies the positive bias on the control grid of a screen grid amplifier 4 to vary the damping of the input tuned circuit 1, 2 and simultaneously varies the screen grid potential derived from the point 10 on the potential divider in such a manner that the amplification of the valve is reduced as said damping in increased and vice versa. To produce this result a resistance 14 is shunted between the slider 11 and the earthed cathode and a fixed supplementary control grid bias may be provided by a cathode resistance 16. In modifications the grid potentials may be supplied from separate ganged potentiometers or varied automatically.

Title: Improvements in electron discharge devices
IPC: H01J1/18
Filed: 1921-08-23
Abstract: 188,108. General Electric Co., Ltd., and Gossling, B. S. Aug. 23, 1921. Vacuum tubes.-A filament cathode comprises at least two loops so arranged that the stability of the filament-anode system is maintained without the use of an auxiliary tensioning device even iu a strong electrostatic field. As shown, two mutually supporting loops 11, 12, crossing substantially at right-angles, are mounted on strips 17, 18 forming a relatively broad base. The loops may be interlocked or -bound together at the centre. The strips are secured to a reentrant stem by clamps insulated by mica. Passage of the electrons from the cathode to the bulb is prevented by closing a cylindrical anode 26, Fig. 4 at one end by a plate 30, and at the other end by a plate 31 with an aperture in the centre to admit the cathode. The aperture may be closed by a metal disc 32, mounted on the strip 17 and having an aperture to admit the strip 18, this aperture being closed by a disc 33 mounted on the strip 18.

Title: Improvements in or relating to fluid flow control devices
Filed: 1949-08-29
Abstract: 672,801. Valves. ROBERTSHAW-FULTON CONTROLS CO. Aug. 29, 1949, No. 22406/49. Class 135. A fluid flow control device, e.g. for thermostatically-controlled gas burners for water heaters, comprises a movable thermo-electrically energized electromagnet having an armature which closes a valve when released and means for moving the magnet into engagement with and for retracting the armature to allow the valve to be opened. Gas passes from the cock 18 to a pilot which, when lit, heats a thermo-couple 80 energizing an electromagnet 74 carried by a cover 68 slidable in the housing 62. The magnet is insufficient to attract an armature 82 slidable in the cover and biassed by a spring 86 to its released position where it abuts a diaphragm 64 to close the valve 38 connected by a spring 67 to the diaphragm. By depressing a button 90 the cover slides against the spring 70 until the magnet engages and holds the armature which is retracted on releasing the button. The valve 38, controlling the passage of fluid from the cock 18 via its seat 40 to the outlet 14, is operated by a thermostatic rod and tube 52, 54 acting through a clicker disc mechanism 50 and over-ride mechanism 42 as described in Specification 590,605.

In an internal combustion engine combined air filter and silencer the latter is formed of the inlet duct in combination with an annular channel surrounding the filter unit, the duct and channel being connected through a buffer chamber which has the effect of providing an increased length of inlet ducting. De-tuning of the system may be increased by anti-resonance holes in the channel walls. As shown, air is sucked by the engine into the inlet duct 4, through the pleated filter 14, into the central space and out through an aperture in plate 7 into the engine. From the duct 4 the air passes into buffer chamber 23, round a wall 20 at each side of filter 14 and then enters the filter compartment at 24.

Abstract: 895,540. Forming glass fibres. OWENS-CORNING FIBERGLAS CORPORATION. June 27, 1960 [Nov. 20, 1959], No. 22473/60. Class 56. Centrifugal fibre forming apparatus comprises a hollow centrifuge rotatable at the lower end of a hollow vertical quill through which a stream of fibre forming material is fed, means within the centrifuge, for distributing the material, comprising a deflector plate disposed across the path of the stream and supported by means extending downwards through the quill and means for directing a blast of gas across the path near the surface of the deflector plate. In the form shown the centrifuge 33 is rotated by a quill 13 and together with the emergent streams 24, is heated by flames from a flame ring 38 fed with an air-gas mixture from a chamber 36, the flames being confined by annular guides 39, 40. The streams are alternated downwardly by a blast from an annular orifice 23. Passing through the quill and surrounding the glass stream 12 are a tube 49 and an inner, eccentric tube 48, the space between which is closed at top and bottom by plates 50, 51. This space is fed with coolant through pipes, one of which, 52, reaches near the bottom while the other, not shown, ends near the top. Passing through the space are a pipe 46 and another not shown, parallel to it, which feed coolant to a hollow box 42 which forms the deflector in the path of the glass stream. A blast is produced across the surface of the box from a slit 57 in a pipe 54 which is in the shape of an arc about the axis of the glass stream and is fed from a pipe 55. This pipe may be fed with air/gas mixture which is burnt to heat the inside of the centrifuge during starting, whereafter air only may be used to deflect the glass stream as at 63.

Filed: 1944-11-14
Abstract: 583,599. Bottling. HALLWORTH, H. Nov. 14, 1944, No. 22491. [Class 125 (ii)] An apparatus for filling bottles or phials singly with a predetermined quantity of liquid, particularly perfume, consists of a frame 10, at the upper end of which is an air pump 11 operatively connected to a beam 15 which is pivotally mounted. The other end of the beam is connected to a treadle, not shown, by a cord 16, and is returned to its position after treadling by a spring 31. A table 20 slides in the frame 10 and is moved in one direction by a lever 21 which is connected to another treadle by a cord 22. A spring 23 returns the table to its orginal position. The lower end of the air pump has a resilient open-ended mouthpiece 25, to receive the neck of the phial 29 placed on the table 20, and the mouthpiece is connected by a pipe 26 of small diameter to an inlet pipe 27, in which is a non-return valve 30, and leading from a reservoir 28 containing the liquid. The first treadle is operated to rock the beam and impart a suction stroke to the piston 13, so extracting air from the phial. A vacuum is created and liquid from the reservoir is forced by atmospheric pressure through the pipes and into the phial. The exact measurement of liquid may be predetermined by controlling the displacement of the piston 13 by. an adjustable screw 18 which regulates the movement of the beam 15.

As described the binary signal at the transmitter is first converted to a 4-level form a i . The signal a i  is passed to a circuit which generates a second 4-level signal di such that d i  = a i -d i-1 . After transmission and filtering a 7-level signal P i  is obtained, P i =d i +d i-1 , and this signal is converted to quaternary form, the resultant signal being converted to binary
