Title: Improvements in or relating to the feeding of steam boiler installations
IPC: F22D3/04
Filed: 1924-08-30
Abstract: 243,094. Siemens - Schuckertwerke Ges., and Stender, W. Aug. 30, 1924. Feed-water, heating.- In feed-water heating plant in which a part of the feed-watar is preheated by gases of combustion and another part by steam, the latter part passes to an accumulator from which it is fed to the boiler, whilst the former portion passes direct to the boiler or tc an economizer from which the boiler is fed. The feed-water is conveyed bv pumps 11, 21, Fig. 1, from a tank 3 to the boiler 1 either through the economizer 12 or through the steam feed-water heater 22 from which the water passes to an accumulator 23. The excess of steam over requirements, on the opening of the automatic valve 6, passes to the heater 22 by way of the pipe 15. The pump 21 can be regulated by the steam pressure in the pipe 5, and a pump 24 supplies the feed from the accumulator 24 to the boiler 1. In the event of the accumulator being emptied on account of excessive consumption of steam, the temperature regulating device which normally controls the pump 11 :s put out of action by the fall of a float 16 in the boiler and the full output of the pump is fed to the boiler. In a modification, the boiler fed by the economizer is separate from the boiler fed by the accumulator, and the two feed pipes are connected by a cross pipe. In another form, the high pressure boiler 10, Fig. 3, is fed by the pump 31 partly with water from a low pressure boiler 1 fed by the economizer 12, and partly with warm water from the accumulator 23, the pump 31 being regulated in accordance with the level of the water in the boiler, the pump 11 in accordance with the pressure behird the the low pressure boiler, and the pump 21 in accordance with the temperature behind the steam feed water heater 22. In the event of the pump 11 supplying more than the pump 21, the excess flows into the accumulator through the pipe 13. In a further form, the whole of the output of the low pressure boiler 21 is supplied to the accumulator whence supplies are drawn by a single pump to the boilers.

Filed: 1976-08-06
Abstract: 1528042 Automatic batch weigher HOWE RICHARDSON SCALE CO Ltd 6 Aug 1976 [19 May 1975] 21121/75 Heading G1N An automatic batch weigher comprises a weigh hopper supported by a lever system connected to a load cell 9, a controlled material feeder, a controlled discharge door in the hopper, a pre-settable weight selector 21 for producing an electrical signal representing a desired material weight and a control unit 30 having digital logic elements and analogue computing elements arrayed in a circuit to receive the electrical signal from the load cell 9 and the electrical signal from the weight selector 21, the control unit 30 comparing the two signals and producing an output signal for the means controlling the feeder to stop the same, as by a cut-off comparator 19 pre-settable by a potentiometer 23, before the delivered weight equals the desired weight to compensate for the weight of material that is delivered to the hopper after the feeder has been signalled to stop and an output signal for the means controlling the hopper door to open the same when the weighing is completed. As described the feeder has a fast and a slow feedrate the slow rate coming into operation on a substantial proportion of the full charge of material having been fed into the hopper. The onset of the slow feedrate is controlled by a dribble feed comparator 18 which is pre-settable by a potentiometer 24. The control logic 30 is also provided with signals representing the tare weight, adjustable by a potentiometer 22 to check whether the hopper has been emptied fully, representing whether the charge of material is under or over the required weight using a comparator 17 pre-set by a potentiometer 25 and representing plant inputs 31 e.g. emergency stop, discharge downstream interlock, bag in place on hopper Figs. 4A, 4C (not shown). The weigher may be checked when required by a proof circuit 34. Automatic taring of the hopper may be introduced by a unit 13 and automatic control of the compensation adjustment by a circuit 15. Signals may be fed to a remote weigh display, printer or data logging equipment 14. The weigher may have a totalizing counter 33 and a batch counter Fig. 3 (not shown). A meter 27 is provided for providing respective readings for adjusting the potentiometers. A means is provided for preventing the opening of the hopper in case of an abnormal condition downstream thereof. The hopper may be fed from a bin in which case a low material level detector may be provided therein. When this detector is operated there is insufficient material for a complete charge and normally the weigher stops. However, the stopping mechanism may be manually over-ridden. The various control buttons, potentiometers, indicators and a mimic display are mounted on a front panel of the batch weigher Fig. 3 (not shown). The circuits are in the form of a plurality of interconnected circuit boards Figs. 4A, 4B, 4C, 4D (not shown).

Title: Improvements to methods of producing foundations in deep water, especially for piersfor bridges
IPC: E02B3/06
Filed: 1959-06-22
Abstract: 876,547. Piers. DUBOIS, L. J. June 22 1959, [July 12, 1958], No. 21354/59. Class 68(2). A bridge pier is constructed by building a column of open-ended reinforced concrete rings 1, 2, 2 and packing filling 8 into the internal cavity. The site for the first ring is prepared by scraping or jettising and the ring itself may have integral jets 18 (Fig. 10) fed through a conduit 19. When sedimentary matter has been removed from the site the ring is lifted and a rockfilling 20 introduced into the cavity thus created. When the foundation is satisfactory it is injected with grout. To prevent undermining of the piers, bituminous stove packing 40 is provided externally (not shown, see Fig. 7). When the first ring has been placed and filled, further rings are positioned with the aid of a guide system comprising guide cables 3, of which one is shown in Fig. 4, which are anchored at one end to the ring 1 and connected by sleeves 5 to the ring being placed. Each ring may also have guide arms to ensure the centring of each ring on the ring immeadiately below it. The pier is anchored to the foundation by bored piles 9 passing through the filling of one or more of the rings, into the bed rock. Pre-stressing of the pier is achieved by cables anchored in the rock and to the head of the pier and subsequently tensioned. When the top of the pier is above water it is capped with a concrete slab 10 which supports columns 12 which carry bridge spans 14. The pre-cast rings are brought to the site by floats and controlled during positioning from an artificial island standing on retractable legs. The rings may have internal remote-controlled floats which are filled and emptied pneumatically and can be detached from the ring when it is in position. In a modification the rings are of oval cross-section, formed by two adjacent rings joined by straight parallel webs.

Abstract: 1,041,367. Aerials; pulse radar. CSFCOMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 29, 1963 [May 30, 1962], No. 21466/63. Headings H4A and H4D. In a radar system with orthogonal polarizatons in two transmitter-receiver channels, phase-shifting means in transmitting and receiving portions of the two channels are adjustable whereby, when the radar system is oriented towards a target carrying an interference source, received interference signals are directed to one receiver and a substantial portion of the echo signals from the target are directed to the other receiver. In an embodiment, a transmitter E feeds aerials CV, CH via respective vertical and horizontal polarization channels and 3dB hybrids J 1 , J 2  incorporating a phase shifter P<SP>1</SP> ganged to a phase shifter P<SP>11</SP> in one section of 3dB hybrids J 3 , J 4 ; the output arms of hybrid J 3  feed respective conventional Rr and " interference " Rb, receivers, and probes S 1 , S 2  in the output arms of hybrid J 4  feed an indicating meter I via a difference amplifier A. A phase shifter P 1  is ganged to a phase shifter P 2  such that the latter introduces twice the phase shift of the former. Duplexers D 1 , D 2  are provided. In operation, assuming no radar transmission, the aerials are moved together until the direction of maximum interference is reached, as indicated by an auxiliary device (not shown) which derives the sum of the video signals from the two receivers; the aerial system is then maintained manually or automatically in the direction of maximum received interference. Phase shifters P 1 , P 2  are adjusted to bring the interference signals at the two input arms of hybrid J 4  into phase, utilizing indicator I; phase shifters P 1  and P<SP>11</SP> are next adjusted until the indicator of receiver Rr gives minimum indication and that of Rb gives maximum indication. Transmitter E is then energized; target echoes are then substantially directed only to receiver Rr. The detection of a target in a direction near that of the target carrying the interference source can be affected by adjusting the phase shifters.

Abstract: 510,638. Butane polycarboxylic acids. JOHNSON, G. W. (I.G. Farbenindustrie Akt.- Ges.) July 20, 1938, No. 21573. [Class 2 (iii)] Butane polycarboxylic acids are produced by oxidising with nitric acid #<4> cyclohexenes which are substituted in at least one of the positions 1 and 2 of the hexene nucleus by carboxylic, carboxylic anhydride, cyano or keto groups. An oxidation catalyst, e.g. an alkali molybdate or vanadate, may be used. The #<4> cyclohexenes are prepared by condensing butadiene or other hydrocarbons of the butadiene series, 'e.g. isoprene, cyclohexadiene, with olefine compounds in which the carbon double linkage is in the alpha position to at least one carboxyl, cyano or keto group, e.g. crotonic acid, maleic acid, maleic anhydride, cinnamic acid, acrylic nitrile, cinnamic acid nitrile, maleic acid dinitrile, vinylalkyl ketones or vinyl benzoyl ketone. In examples (1) #<4>-cyclohexene-1-2 dicarboxylic anhydride is oxidised to butane- 1.2.3.4-tetracarboxylic acid and by boiling this with acetic anhydride the dianhydride is obtained ; (2) 2 - phenyl - #<4> - cyclohexene-1- carboxylic acid is oxidised to 2-phenylbutane- 1.3.4-tricarboxylic acid; (3) #<4>-cyclohexene-1- methyl ketone is oxidised to butane-1.2.4- tricarboxylic acid; (4) #<4>-cyclohexene-1-nitrile is oxidised to a mixture of butane-1.2.4- tricarboxylic acid and 2-cyanbutane-1.4-dicarboxylic acid.
