Title: Steam power plant with intermediate superheating
IPC: F22B35/06
Filed: 1960-10-12
Abstract: 885,114. Steam superheaters. SULZER FRERES S.A. Oct. 12, 1960 [Oct. 22, 1959], No. 35001/60. Classes 123(2) and 123(3) In a steam power plant in which intermediate superheating is carried out in tube panels 10 disposed in the radiation zone of the steam generator 1 protection against burning during starting up is afforded by forming the outer tubes of each panel, which are most intensively subjected to radiation, as double tubes. As shown the intermediate superheater of the steam generator 1 comprises five panels of tubes 10 each of which is formed of an inner part 11 constructed of five nested tubes 26 connected in parallel between headers 13, 14 and an outer protective part 12 consisting of five double tubes 17, 20 connected respectively between inner tube headers 18, 19 and outer tube headers 15, 16. The tubes 20 of the outer part 12 are of larger diameter than the tubes 11, and the outermost tube 20 of each outer part 12 may be larger than the remainder of the tubes 20. A pump 33 forces water successively through two economisers 22, 23, wall tubes 5, a primary superheater 24 and through the inner tubes 17 of the outer parts 12 of the tube panels 10 to a final superheater 21 leading to a high-pressure section 30 of a turbine. Expended steam for reheating passes first to the outer tubes 20 of the outer parts 12 of the tube panels 10 and then through the tubes 26 of the tube panel inner parts 11 before being fed to a low-pressure section 37 of the turbine. On starting up the plant water is fed through the tubes 17 to cool the outer tubes 20 of the reheater.

Title: Improvements in metering pumps
IPC: G01F3/18
Filed: 1933-12-14
Abstract: 420,202. Fuel-injection pumps. EXCELL-O AIRCRAFT & TOOL CORPORATION, 1200, Oakman Boulevard, Detroit, Michigan, U.S.A. Dec. 14, 1933, No. 35189. Convention date, Dec. 23, 1932. [Class 102 (i)] In a fuel-injection pump a number of parallel cylinder bores 31, Fig. 2, are arranged around a central distributing valve 105, the pistons 65, 68, &c., being reciprocated by an inclined disc 97 on the driving shaft 102 overlaid by a loose disc 93. The pump body comprises sections 20-23 held together by tie rods. Sliding rods 81 are interposed between the pistons and the disc 93 and the pistons are pressed towards the disc by springs 78 acting on sleeves 76 which engage the pistons. The valve 105 is coupled to the shaft 102 by a rod 108 sliding in a socket in each part and carrying a pin 112, which engages inclined slots 113 in the shaft 102, and a pin 110, which engages axial slots 107 in the valve. The latter is formed with a groove 114, which communicates with the suction pipe, and with a land 115, which periodically closes the suction ports 32<a>, 35<a> &c., to permit discharge through pipes 39, 42, &c., the latter being provided with check valves 58. The land 115 has an axial leading edge and an inclined trailing edge, so that axial adjustment of the valve by means of a pinion 122 and lever 125 effects adjustment of the amount of discharge. The timing of injection is adjusted by rotation of the valve relative to the shaft 102, this being effected by axial movement of the spindle by means of a pinion 117 and a lever 120. In a modification illustrated in Fig. 11 by a development of the valve 105, suction and discharge take place through the same cylinder ports 32<a>-37<a>. The land 115 is formed with a recess 126, which is connected by means of an axial passage 136 in the valve with a recess 134, the latter co-operating with discharge passages 127-132. The passage 136 may be provided with a check valve. The leading rim of the land 115 maintains the ports 32<a> &c., momentarily closed before opening them to discharge, thus causing a rise in pressure. The leading rim may further be provided with a groove 144 opening to the suction space 114, so that some of the fuel is byepassed, the amount being variable with the speed. In a further modification, Fig. 16, the rotary valve 150 is provided with two or more lands 166, 167, having recesses 168, 169 connected by a common passage 170 in the valve with an inclined recess 171. The recesses 168, 169 co-operate with the cylinder ports 159-162, while the recess 171 co-operates with the discharge passages 172-176. This arrangement effects a preliminary discharge at low pressure from one cylinder, followed by a discharge at high pressure from another cylinder. The amount of the discharge and the timing of injection are varied as in the prior arrangements. In order to prevent drip, the discharge passages may be connected to the suction space 163 by means of a recess 185 and passages 186, 188 provided with a check valve 191.

Abstract: 1,194,916. Walking mechanisms. O. REIMANN. 1 Aug., 1967 [1 Aug., 1966], No. 35263/67. Heading B7H. A walking mechanism for apparatus such as an excavator, pile driver or drilling device comprises a stand surface 3, walking shoes 4, which may be raised and moved longitudinally of the mechanism and each have a rail 12 on the upper side, cross-beam guides 6 arranged transversely of the mechanism and each guiding a crossbeam 7 therein, a hydraulic or other pressuremeans lifting cylinder 8 at each end of each cross-beam 7, a roller 13 engageable with a rail 12 mounted on the downwardly movable pistonrod 10 of each cylinder 8 and shifting cylinders 16 which are articularly connected by gimbal mountings to a cross-beam and to the walking shoes 4. In operation, to move the apparatus longitudinally the cylinders 8 are first expanded to lift the stand surface, which is shown as a pair of shoes 3, and the apparatus clear of the ground. The apparatus is then moved longitudinally on the rails 12 by the cylinders 16, the cylinders 8 are contracted to lower the apparatus and raise the walking shoes 4 and the cylinders 16 are operated to bring the walking shoes to the starting position relative to the apparatus. The cylinders 16 may be operated in opposite senses to rotate the apparatus and hydraulic cylinders 20 may be operated to move the apparatus side. ways. The stand shoes may be extendable by extension pieces or may be provided with base supports when working on slopes. In a development the walking shoes and stand shoes may be alternatively movable longitudinally relative to the apparatus.

Title: Apparatus and method for reproduction of character matrices
IPC: B41J2/515
Filed: 1973-07-24
Abstract: 1432437 Printers MEAD CORP 24 July 1973 [25 July 1972] 35286/73 Heading G4H A character printer has two spaced rows of marking elements, and a read-only memory read out to produce two series of parallel signals to control the two rows respectively to build up a character matrix, the two series having a relative delay corresponding to the spacing between the rows. As disclosed, a line of characters are printed concurrently using two rows of ink jets producing streams of drops, each drop being charged or not so that it is deflected away from the paper or not. The two rows are laterally staggered so that one row prints oddnumbered columns of each character matrix and the other prints even-numbered columns. The paper moves perpendicularly to the length of the line, and the two rows have a relative spacing in this direction so that the lateral spacing may be close enough that the ink spots in a given character matrix overlap to give continuous strokes. There is a section of the read-only memory for each possible character. In one embodiment, selected flip-flops in an array of steering circuits are set in turn under control of a decoder responsive to codes representing the characters to be printed in the line, received serially-by-character, parallel-bybit, the decoder output being gated to the appropriate steering circuits under control of a column select shift register. All the sections of the read-only memory are then read out together by a row select shift register, to the steering circuits which route them to charge rings associated with the ink jets. Four jets in each row are concerned with printing a given character in the line so each section of the read-only memory provides a series of 8-bit bytes. In another embodiment, the first 8-bit byte for each character in the line in turn is loaded into a shift register under control of the character-code decoder, then the register contents are used for printing, then the second 8- bit bytes are loaded, &c. Thus the sequence of character codes has to be applied to the decoder once for each row of the character matrix.

Title: Dispensing machine for delivering bulk fuel in measured quantities
Inventor: CLEGG FREDERICK WILLIAM
IPC: G07F13/04
Filed: 1961-10-02
Abstract: 939,406. Coin freed vending apparatus; weighing apparatus. NOVOTECHNICS Ltd. Sept. 13, 1962 [Oct. 2, 1961], No. 35551/61. Classes 27 and 143. A vending machine transports coal from a hopper 1 to a pivoted scuttle 12 where it is weighed and a measured quantity is held in readiness for a purchaser who can inspect the contents of the scuttle and read its weight through windows 5 and can obtain delivery by inserting coins into slots 8 to release levers 20 projecting from the machine by means of which the purchaser tips the scuttle to pour its contents into shoot 2. As soon as the scuttle 12 is restored after delivery of its contents, conveyer 31 is driven to fill the scuttle in readiness for the next purchase. The scuttle is pivoted on a table 15 raised on legs 16 from the weigh platform of a weighing machine with an indicating pointer 7. The downward pivotal movement of the scuttle and arms 20 propels a chain drive causing the upward displacement of a sliding door which normally closes the shoot 2. The conveyer 31 delivers a larger size of coal until the required weight is nearly achieved, the scuttle being topped up with a smaller size by means of a jigging conveyer 46, Fig. 5, until the right weight is reached. Control circuit.-Insertion of coins frees a pull rod 10 by raising a catch 54. Operation of the pull rod works a cam to operate contacts 56 to energize relay 57 which energizes solenoid 50 to withdraw catch 9 thereby allowing levers 20 to be depressed and the scuttle to be emptied into the shoot 2. Relieved of the contents of the scuttle the weigh beam 49 pivots to open contacts 63 and make contacts 62. When levers 20 return upwards they operate contacts 59 to release the solenoid 50 and re-engage the catch 9. Contacts 60 engaged by the catch 9 operate relay 61 to start conveyer motor 45. As the scuttle fills, the weigh beam 49 reflects until contacts 62 break to stop the conveyer 31 and contacts 63 make to energize relay 64 which starts the jigging conveyer 46. The final position of the weigh beam is determined by a shutter 65 which interrupts light from lamp 66 to photo-cell 67 and by releasing relay 64 stops the jigging conveyer. While the conveyers are in operation a solenoid 75 is released to lock the pull switch 10. Should the photo-cell fail to stop the conveyer, the weigh beam deflects contacts 68 to disconnect the power supply. Power is also disconnected if the hopper is exhausted and the conveyers run beyond a period set by a timer 73. Whenever power is cut off a solenoid 72 releases a flap 71 to close the coin slots 8.

Filed: 1958-11-06
Abstract: 874,738. Tubular heat exchangers. HUNT & MOSCROP Ltd. Nov. 3, 1959 [Nov. 6, 1958], No. 35622/58. Class 64(3) [Also in Group XXVII] Hot gases, e.g. exhaust gases of an I.C. engine, pass up through a casing H from an inlet h to an outlet h<SP>1</SP>, either through a small by-pass passage 3 or a larger-sectioned passage 2 containing a gilled coil M with a vertical axis, according to the setting of dampers N. Water of a circulating system for heating rooms or a vehicle space is heated by being passed down through the coil M from an inlet m<SP>1</SP>. The dampers N are interlinked and are operated by compressed air or an electric motor controlled by thermostats in the circulating water system or in the heated room or vehicle. Three dampers are shown open to the passage 2 and the damper to the bypass 3 is therefore closed, for heating of the water coil M. Because of baffles n' in the by-pass and of the coil M, the.heater acts as a silencer for the exhaust gases.

Title: Methods of detection of air space or submarine targets by reflection of electromagnetic or acoustic waves
IPC: G01S7/292
Filed: 1972-07-31
Abstract: 1368717 Pulse radar J B G PEROT 31 July 1972 [18 Aug 1971] 35625/72 Heading H4D A method of detecting targets by the reflection of wave energy comprising a first scanning operation wherein all points in an area are scanned rapidly with a high false alarm probability and a second scanning operation wherein the only points investigated are those resulting in a "target" indication in the first scanning operation. An airport approach radar uses computer control of a square phased-array antenna to provide a coverage of 120 degrees azimuth, range 20-250 km. and a maximum altitude of 20 km. The transmitting and receiving antennae are similar (Figs. 3, 4) comprising a single source or receiver in front of an array of reflectors arranged in a 250 x 250 matrix. The reflectors are formed by shortcircuited transmission lines including switching diodes which vary the position of the short circuit. The direction of the antenna radiation pattern is adjusted in azimuth and elevation by addressing the switching diodes from a computer to vary the phase relationship of signals reflected from the matrix. Control 20 has stored therein details of the scanning required for each range sector in both "search" and "identification" modes. The control 20 operates a search transmitter recorder 24 and a search receiver recorder 29 which align the phased array antennae 25, 26 in the correct azimuth and elevation. Echo signals are passed to a receiver 22 and those above a threshold are counted to indicate a "target", The co-ordinates of "targets" are read into identification transmitting and receiving recorders 27, 30. After completing the search scan of a particular range sector the recorders 27, 30 are connected to the phased arrays 25, 26 and the "targets" are examined more closely to identify real targets. After completion of the identification mode the search recorders 24, 29 are reconnected and range control 28 advances to the next range sector. Transmitter pulse length is varied from range to range as is the number of scans in each range sector in order to maintain a constant probability of detection. In the identification mode data processor 31 computes a predicted target position and a small area around this position is scanned several times to provide a low probability of false alarm (e.g. 10<SP>-5</SP>). The use of sound waves is referred to, but no specific details given.

Abstract: 978,846. Controlling aircraft. DORNIER-WERKE G.m.b.H. Sept. 11, 1963 [Sept. 14, 1962], No. 35789/63. Heading B7G. An aircraft control transmission includes two lever arms 8, 9 (Figs. 1 and 2), of equal length, pivotally connected together at one end b, the angle between the arms being varied according to the aircraft's forward speed to vary the transmission ratio of the linkage. The aircraft described is fitted with direct lift engines, whose fuel flow control 3 is coupled to the aileron control, for lateral control, through the levers 8, 9 and a further lever 6 which is movable longitudinally by a further lever 5, about which the lever 6 pivots, actuated by a dynamic pressure sensor 4. Fig. 1 shows the high speed configuration in which movement of the control stick 1 does not affect the fuel control 3, but only the aileron 2, and Fig. 2 shows the low speed configuration in which movement of the control stick causes levers 8 and 9 to rotate about a pivot c, and lever 6 to rotate about the lever 5 to actuate the fuel control 3. In a modification (Fig. 4), equal length levers 23, 24 are provided, the lever 23 being rotatable about the pivot g connecting them by a rod 28 leading to a dynamic pressure sensor. When the levers 23, 24 are thus relatively angularly displaced, movement of a rod 27 connected to the control stick causes the levers 23, 24 to rotate about the shaft and actuates the fuel control by rotating a rod 26. In a further modification (Fig. 7) the lever 23 is replaced by a disc 23<SP>1</SP> rotatably mounted in a disc 21<SP>1</SP> rotatable by the dynamic pressure sensor through a rod 28<SP>1</SP>. When the disc 211 is thus rotated so that the pivot h<SP>1</SP> of the levers 24<SP>1</SP>, 26<SP>1</SP> is not aligned with the centre of the disc 23<SP>1</SP>, movement of the lever 25<SP>1</SP> connected to the control stick will produce movement of the lever 26<SP>1</SP> leading to the fuel control. The apparatus may also be used for pitch and yaw control and may be adapted to vary the lift engine nozzle area instead of its fuel flow. The speed may alternatively be sensed by radar equipment.

The element has small cross-sectional area so as to render the spiral turns flexible. Each spider has element guides in the upper surfaces of its arm portion 21, 22, Figs. 4, 5 (not shown), arranged so that if an element is engaged by the base of the guide on arm 22 the guide on arm 21 is recessed to clear the element. The adjacent elements have the reverse arrangement. The spiders are loosely located in the bowl 13 by guides 17, Fig. 1 and 18, Fig. 4 (not shown). The bowl is held against the plate through a resilient spacer 54 by spring and lever means, Fig. 7 (not shown), which provide a bias greater than that of the star spring 40, the lever part engaging in the notches 48, Fig. 3. The star spring carries an earth terminal 47 or may be replaced by series of separate springs, Fig. 8 (not shown). The bowl has a high reflectivity surface towards the element and a high emission surface facing outwards. The latter may be produced by colouring or anodizing. The bowl may be cast and has a large thickness to spread any absorbed heat evenly. A temperature sensor 33 of the non integrating type comprising a temperature dependent resistance between electrodes is arranged to occupy a spiral turn of the element, the element being passed round the sensor between ends 31, 32, Fig. 2. A spacer 35 locates the sensor between the element turns of the parts 24, 25.
