Title: Automatic apparatus for lighting and extinguishing gas lamps
IPC: F23Q9/02
Filed: 1919-09-16
Abstract: 155,888. Radet, L. Sept. 16, 1919. Clockwork-actuated valves.-In gas lighting and extinguishing apparatus operated at predetermined times by clock-work mechanism wherein the gas burner and pilot light are operated so that one lights the other before being extinguished, the gas valve comprises a rotary distributor disk 15 which moves over a distributing plate 7 communicating with the pilot and burner pipes 12, 14 respectively, a hand-operated pushrod e also being provided for operating the valve at any time to supply gas to the main burner. The valve is enclosed in a cover 6, and it is maintained on its seating by a spring 21. Gas is admitted to the valve chamber 5 through ports 10, 16 in the seating 7 and disc 15 respectively, and passes through the port 11 or 13 to the pilot or burner according as these are unmasked by perforations 17, 18 or 19, 20 in the valve disc when this member is moved into position by a lever 24 through the tappets on the actuating-dial. In the position shown in Fig. 2, the tappet on the dial circumference 32<a> has engaged the end 32 of a lever 26 and pushed it back against a spring 28 sufficiently far for the lever 24 to be free to move the disc 15 under the action of the spring 25, so that gas now passes to both the pilot light and main burner. In this position, the pin 31 engages the step 30 on the arm 26, as shown in Fig. 4. As the distance between the perforations 17 and 18 and the perforations 19 and 20 is less than the diameter of the ports 11, 13, the pilot and main burners are maintained alight in the movement of the disc 15 preliminary to the extinction of either burner. Continued movement of the tappet pushes back the arm 26 to release the lever, so that, under the action of the spring 25, it moves the disc into a position in which the burner supply passage 13 registers with the port 20, the pilot passage being masked by the disc 15 and the pilot is extinguished. At the predetermined time for extinguishing the main burner, a tappet on the circumference 24<c> of the actuating dial engages the lower end of the lever 24 and moves it against the spring 25 until the pin 31 engages the step 29 of the lever 26. During this movement, the valve disc 15 has been moved to cut off the gas supply to the main burner, and the pilot light is thus ignited. By means of the rod e, the lever 24 can be manually disengaged from the lever 26 at any time, when the disc is moved by the action of the spring 25 to rotate the disc 15 into a position to supply gas to the main burner.

Title: Improvements in or relating to process and system for treating hydrocarbon oil with liquid hydrogen fluoride
Inventor: GIACHETTO JOHN J
IPC: C10G17/07
Filed: 1952-09-11
Abstract: A hydrocarbon charging stock boiling above the boiling range of gasoline, containing sulphur compounds and water, is treated with liquid HF to produce a solution of H2O, H2S and other sulphur compounds in liquid HF and an HF-immiscible purified charging stock, respectively, the solution being evaporated to produce a first vapour stream, consisting of all the free H2S in the solution, HF and H2O, and a first liquid residue which is evaporated to produce a second liquid residue and a second vapour stream, consisting of HF and H2O containing no H2S, which is fractionally condensed to produce a minor proportion of a condensate, consisting of HF and H2O containing HF in excess of the concentration of HF in an HF-H2O azeotrope, and a third vapour stream consisting of anhydrous HF, the condensate being fractionally distilled to produce a fourth vapour stream of anhydrous HF; the first, third and fourth vapour streams being condensed and recycled to the treating process.  The second liquid residue may be subjected to thermal decomposition to produce a residue of tarlike hydrocarbon material and a fifth vapour stream comprising HF, H2O, H2S and hydrocarbon gases, the fifth vapour stream being fractionally condensed to produce a condensate of HF and H2O containing substantially no H2S and a sixth vapour stream of HF, H2S and hydrocarbon gases, which condensate is recycled to the treating process, H2S being withdrawn from the sixth vapour stream and from the process.  The fractional distillation of the condensate which produces the fourth vapour stream also produces an azeotropic HF-H2O bottoms fraction, a portion of which is contacted with the sixth vapour stream to selectively absorb HF which is recovered and recycled to the treating process.

Abstract: 803,049. Gyratory crushers. NORDBERG MANUFACTURING CO. July 19, 1957 [July 27, 1956; May 8, 1957], No. 22939/57. Class 59 In a gyratory crusher comprising a pair of crushing members at least one of which has a liner providing a space between the crushing member and the liner for receiving a fluid backing material, e.g. molten zinc, means are provided near the upper end of the space for controlling the overflow of excess backing material and preventing it from reaching parts of the crusher which could be harmed or be rendered inoperative by contact with the material. As shown, a mantle 26 is provided adjacent its upper edge with at least two holes 34 which provide access to the space between the mantle and a crushing head 22 for pouring backing material 28 and determine the level 36 of the backing material. The level of the holes 34 is such as to prevent the backing material from reaching the screwthreads 24 between a nut 32 and the mainshaft 20. The mantle is engaged at its upper end by an extension 30, and a washer 42 is disposed between a ground surface 40 on the extension 30 and the lower edge of the nut 32. To protect the washer 42 from abrasion, a rib 44 is provided on the mantle extension 30 to form an annular trough 46. A feed plate 50 is protected from abrasion by means of a peripheral wall 52. To prevent relative rotation between the mantle 26 and the mantle extension 30, which is interlocked with the nut 32, a lug 56 on the mantle engages a corresponding lug 54 on the mantle extension. The space between the bowl 14 and its liner 18 is filled with backing material 72 which is poured in from above. The bowl has screwed thereto a tightening ring 70 which has an integral diagonal portion 74 provided with spaced lugs 76 on which rest, when the ring 70 is tightened, spaced lugs 78 provided at the upper end of the liner 18, the spaces formed between the lugs serving as overflow channels for the backing material. A feed cone 82, 84 rests on the upper end of the liner 18. Various modifications are described in which (a) the holes or notches provided adjacent the upper edge of the mantle are substantially inclined to the vertical, (b) the lower edge of the feed cone is provided with notches interlocking with lugs at the upper edge of the bowl liner, (c) the lower edge of the tightening ring is horizontal, (d) an adapter ring is provided for backing the mantle extension, (e) an adapter ring is provided between the bowl and its tightening ring, or (f) the mantle comprises albutting upper and lower portions, the cross-section of which at the abutting edges is of fluctuating formation so that they are locked together by the backing material.

Title: Data transmission system
IPC: G08C15/12
Filed: 1972-05-16
Abstract: 1354063 Selective signalling PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 May 1972 [19 May 1971] 22953/72 Heading G4H A time-division-multiplex arrangement transmits the change in a signal value. A potentiometer 10 in an adjusting point 1 supplies a voltage via a low-pass filter 11, 12 to a storage capacitor 13, the capacitor voltage being passed via a multiplexing switch 2 to a detector 15 which by means of differential amplifiers 18, 19 and a NAND gate 24 (or a single such amplifier with feedback could be used) produces a 1 signal from the NAND gate 24 if the voltage is not in a reference range, whether the voltage is above or below the range being indicated by a sign bit from amplifier 18. The 1 signal from NAND gate 24, throughout its duration, causes a clock pulse generator 31 to gate (at 30) charging/discharging current (from a diode bridge 25-28) of polarity determined by the sign bit to cancel the voltage on capacitor 13, achievement of cancellation terminating the 1 signal from NAND 24. This signal, while present, gates (at 32) clock pulses from 33 to a counter 35. Provided there was at least one pulse to counter 35, a delay 37 enters the count into a shift register 36 which also receives the sign bit and the identity of the adjusting point 1 from an address source 38. Termination of the 1 signal from NAND gate 24 gates (at 40) clock pulses from 33 to shift out register 36 to a transmission path 42. The address source 38 is advanced via a delay 41 and selects another adjusting point, e.g. 1<SP>1</SP>, at multiplexing switch 2. The count signal transmitted of course represents the change in setting of the potentiometer in the adjusting point since the last selection of that adjusting point by the multiplexing switch 2. At a receiver 43-48 controlling a TV camera, the transmitted signals are entered into a shift register 43, the identity of the adjusting point addressing a store 44 to obtain the previously transmitted value from the adjusting point which is incremented or decremented at 48 by the latest transmitted count according to the associated sign bit and stored back in 44. The updated value is subsequently converted to analogue form at 46 and applied via a demultiplexing switch 45 to an appropriate control store, e.g. 47. Extra bits may be entered into shift register 36 to select the camera (i.e. the receiver 43-48) to be controlled. Calibration values may be entered into the store 44 by an operator at the receiver during a calibration operation.

Abstract: 921,647. Hinges. A. R. BAER. June 26, 1961 [July 15, 1960], No. 23025/61. Class 65 (2). A hinge structure comprises two intermeshed geared hinge members 11, 12 each of which has an outwardly extending leg portion 16, 19 and a wedge-shaped cut-out portion 24, 25 the apex of which coincides with the axis of rotation of the member, and a C-shaped clamp 13 the inwardly turned ends of which contact the members at their axes of rotation and hold them in mesh. The clamp is preferably made of springy material, but it can be rigid. The hinge may be assembled by holding the members as shown in Fig. 2, engaging the clamp, and then rotating the members to the position shown in Fig. 3. For a normal hinge the hinge members are formed with their teeth on circular arcs, but the hinge can be designed to have a self-opening or self-closing action by forming the teeth of one or both of the members on the surface of a spiral, the inwardly directed spring force of the clamp tending to rotate the members to the position in which their axes of rotation are closest together. The hinge members can also be made to assume one or more relative angular positions by flattening the generally circular arcs at suitable points. The hinge is particularly intended for use with folding doors, the hinge members and clamp extending along the edges of the door panels and being formed preferably by extrusion. The hinge elements can be made of metal, such as brass or aluminium, or of thermoplastic material.
