Title: Method of starting through-flow type boiler plants
IPC: F22B35/14
Filed: 1963-12-02
Abstract: 1,055,989. Starting forced flow boilers. HITACHI Ltd. Dec. 2, 1963 [Dec. 4, 1962], No. 47538/63. Heading F4A. A method of starting a through flow type boiler plant comprises decreasing the fuel flow rate when the fluid pressure upstream of the heating sections exceeds a predetermined value thereby reducing by-pass flows and permitting the size of by-pass circuits to be kept to a minimum. The plant comprises a feed pump 1, Fig. 1 (not shown), supplying water from a deaerator 14 to a boiler 2 and a superheater 3 from which vapour passes through a turbine 1] to a condenser 12, a feed water heater may be provided before the pump. Superheater and turbine by-pass circuits containing pressure relief valve 5 and turbine by-pass valve 7 respectively lead to a flash tank 8 which is connected to a condenser by steam and water lines 18, 19. During starting only part of the fluid is vaporized whilst the unvaporized water, as it is forced through the system causes the pressure to rise and opens valve 5, through which it then flows. To reduce the maximum by-pass flow, the fuel flow rate to the boiler is reduced as the by-pass flow increases by controlling the fuel flow valve 16 in accordance with signals indicating the opening of valve 5. As the by-pass flow decreases and valve 5 closes, the normal fuel flow is restored.

Title: Camera
IPC: G03B17/18
Filed: 1976-11-16
Abstract: 1527306 Camera indicators FRANKE & HEIDECKE GmbH [Trading as ROLLEIWERKE FRANKE & HEIDECKE] 16 Nov 1976 [20 Dec 1975] 47693/76 Heading G2A The exposure time and/or the diaphragm aperture in a camera can be set automatically in dependence on subject brightness, or manually, and an indicator device comprising a number of light sources shows the difference, in the case of manual setting, between the value set manually and the value which would have been set automatically. Section 1 of the circuit shown determines the optimum setting, either of exposure time or aperture setting, in accordance with the subject brightness as measured by a photocell 6. Potentiometer 3 is set according to the film sensitivity. If the exposure time is set automatically, the diaphragm aperture is set manually by potentiometer 4, and the automatic exposure can be switched out in favour of manual setting by potentiometer 5. Similarly if the aperture is set automatically the exposure time is set manually by potentiometer 4 and the automatic aperture setting can be switched out in favour of manual setting by potentiometer 5. The changeover from automatic (A) to manual (M) setting is governed by a changeover switch 15 forming part of an asymmetric astable multi-vibrator 14. This is switched off in the A position, and in the M position presents a series of pulses to the bases of transistors 12, 13 forming the electronic part of the changeover switch. Potentiometers 3, 4 and 5 are connected to an analogue computer 2, the output signal from computer 2 passes to an analoguedigital converter 16 which converts to a corresponding digital combination. A decoder 17 decodes the digital combination and actuates one of eight outputs, each of which can light up one of the luminous diodes in an array 18. Each diode indicates either a specific exposure time or a specific diaphragm setting when the camera is being used with automatic timing or diaphragm (switch position A). With manual operation (switch position M), a long pulse is presented to transistor 12, but only a short pulse to transistor 13. Thus two diodes are lit up alternately by light flashes of different duration, corresponding to the value set manually and the value which would have been set automatically. These may be brought into coincidence by adjusting potentiometer 5. Instead of being of different duration the two light signals can be of different brightness or colour. They may be arranged to be visible in the view-finder.

Filed: 1974-11-06
Abstract: 1486236 Reciprocating pumps YOSHINO KOGYOSHO CO Ltd 6 Nov 1974 [7 Nov 1973] 48051/74 Heading F1A A spray producer comprises a container 1 for liquid to be sprayed, a nozzle 6 mounted in an actuator head 7 and being communicable with said liquid in said container through a hollow piston 8, a pressure chamber formed within a cylinder 4, a suction chamber 10 and a conduit 11, a vertically movable valve rod 12 being provided in said piston and in said chambers and having an upper portion 13 which normally closes a passage 15 communicating between the-nozzle and piston interior under the action of a compression spring 14 but which moves downwardly to allow liquid flow through said passage to the nozzle on the attainment of a predetermined liquid pressure in the pressure chamber caused by depression of the actuator which effects depression of the piston mounted therein. An annular member 18 is positioned between the pressure and suction chambers to define a recess within which an elastic ring 16 slidably mounted on the rod 12 is movable between an upwardly facing shoulder 17 and a downwardly facing shoulder of member 18, the said member 18 having one or more grooves in its downwardly facing shoulder that allow liquid flow from suction chamber 10 to the pressure chamber when the ring 16 abuts said downwardly facing shoulder, said liquid flow being prevented when the ring seats on the shoulder 17. Thus, in use, the piston and rod are depressed, passage 15 being closed, and air from the pressure chamber is exhausted when air grooves 28 in the rod surface make communication between the pressure and suction chambers. The piston and rod are then allowed to move upwards and ring 16 moves upwards to abut the downwardly facing shoulder of member 18, liquid then being sucked into the pressure chamber. The piston and rod are then depressed once more, ring 16 moves into abutment with shoulder 17 and liquid pressure builds up in the pressure chamber until rod 12 moves downwardly to open passage 15  to spray liquid through the nozzle. In a modification, the rod does not extend within the piston but is operable to close the liquid passage therein by abutting the lower end thereof, and the spring extends between a flange (23) Fig. 5 (not shown), on the upper portion of the rod and the bottom of the pressure chamber or member 18. In a further embodiment, the rod comprises an upper and a lower part (12a), (12b) Fig. 7 (not shown), respectively, said rod parts being interengaged by a guide rod (25) provided on one said part which is slidable within a tubular portion (26), provided on the other part.

Abstract: 1483488 Colour television SONY CORP 19 Nov 1974 [29 Nov 1973] 50120/74 Heading H4F Colour television apparatus is controlled to automatically receive either a PAL colour television signal or a SECAM (Registered Trade Mark) colour television signal by a discriminator circuit 9 controlling a switch 8 to connect the output of either a PAL demodulator 7P or a SECAM demodulator 7S to a matrix 10. In the SECAM signal the B-Y subcarrier is at 4À25 MHz and the R-Y subcarrier is at 4À40625 MHz. The discriminator circuit 19 includes a band-pass filter (14, Fig. 6, not shown) to select the bursts of one of these SECAM subcarrier frequencies, occurring during every second line period, which bursts are passed via an envelope detector (16) to a half-line frequency tuned circuit (17) which provides an output when a SECAM signal is being received, this signal being converted into a D.C. signal which controls switch 8. If the band-pass filter is such as to select the bursts of 4À25 MHz it produces no output when receiving a PAL signal having bursts at 4À43 MHz, whereas if the band-pass filter is tuned to 4À42 MHz so as to select the bursts of 4À40625 MHz it passes all the PAL bursts at 4À43 MHz; in either case the half-line frequency tuned circuit provides no output when a PAL signal is being received and switch 8 connects the output of PAL demodulator 7P to matrix 10.

Title: Forming aromatic compounds electrolytically
IPC: C25B3/23
Filed: 1964-12-11
Abstract: Acyloxy derivatives of polynuclear aromatic compounds are made by electrolysing an anhydrous mixture of the aromatic compound e.g. naphthalene or methyl naphthalene, an alkanoic acid, the sodium salt of the acid, and preferably also the anhydride of the acid, which also acts as solvent.  Where alkanoic acids of higher molecular weight are used, formamide, or acetonitrile may be added as solvent. Polynuclear aromatic compounds include naphthalene, and alkyl naphthalenes, phenanthrene, pyrene; indene; quinoline, dibenzopyridine, phenazine, and like 5 plus 6 ring compounds e.g. including coumarone and thi<\>aa naphthene.  Suitable alkanoic acids are acetic, propionic, hexanoic acid and branched chain acids e.g. trimethyl acetic acid.  The anode used is lead dioxide which suppresses side reactions, and is made by plating a carbon rod using a bath containing lead nitrate and a little copper nitrate, and neutralizing acidity by adding PbO to the bath at intervals.  The number of acyloxy groups introduced into the aromatic nucleus is controlled either by duration of electrolytic treatment i.e. quantity of power applied, or by adjusting the concentration of the alkali salt.  When 1/4 of the aromatic compound is consumed the product consists of the mono-derivative; at 1/2 consumption both mono- and diforms are present, and by continuing electrolysis (or increasing C.D.) the higher products are made.  A graph of this relationship is given. Alternatively, with a concentration of the sodium salt at 5-20 g.p.l., the dicompound is suppressed, but at double this concentration the dicompound is pre-dominant. In examples, a mixture of 8 g. sodium acetate, 25.6 g. naphthalene, 60 c.c. of glacial acetic acid and 60 c.c. of acetic anhydride are electrolysed using the PbO2 anode and a graphite or metal cathode, in an inert atmosphere.  The anode may be rotated or submitted to ultrasonic vibration.  A current of 1.5A at 47V is applied for 160 minutes. The product is 56% naphthalene, 29% naphthyl acetate, 8% naphthalene diolacetate, and the balance higher acetates.  By increasing the sodium acetate content to 16.4 g., the product contains 5% of the mono-derivative and 23% of the di-derivative.  Naphthalene is removed by sublimation, and the residue extracted and fractionated.  Other examples describe tri- and tetraforms.
