Title: Improvements in and pertaining to the distillation of pulverulent fuel
IPC: C10B47/22
Filed: 1937-10-04
Abstract: 490,107. Distilling powdered fuel. BORMANN, O. Oct. 4, 1937, No. 26873. Convention date, Oct. 30, 1936. [Class 55 (i)] Pulverulent fuel is distilled by being allowed to fall freely through externally heated tubes, the distillates being drawn off from a gas collecting chamber formed between tube systems arranged one above the other. The fuel is fed from an inlet 26 and falls through tubes 27, the ends of which project into a gas collecting chamber 30, and just above the top of a lower system of tubes 28 into which the partially distilled fuel passes. The tubes are heated externally by hot gases which enter by pipe 23, and, after heating the lower tube system, pass by a pipe 24 to around the upper tubes and an outlet 25. The distillates are led off by a pipe 29 from the collecting chamber 30. Openings for escape of the distillates may be made in the part of the tubes 27 extending into the chamber 30. The Specification as open to inspection under Sect. 91 describes apparatus in which damp fuel from a hopper 1 is dried in a tube 3 by hot combustion gases from a distilling apparatus 10. The dried fuel is separated from the hot gas in vessels 4 and 5, the larger pieces being ground by a mill 6 and returned to the dryer. The dried powder is fed through vertical tubes in the distillation apparatus 10 externally heated by gases from a burner 13, and the residue is removed by a valve 14, the distillates passing to a recovery plant 17. The temperature of the gases from the burner 13 may be reduced by addition of combustion products from chimney 8. This subject-matter does not appear in the Specification as accepted.

Abstract: 730,284. Tubular heat-exchangers. FOSTER WHEELER, Ltd. Feb. 3, 1953 [Nov. 16, 1951], No. 26949/51. Class 64 (3).  Relates to shell and tube type heat-exchangers in which double-walled or "leak-proof" tubes are employed in order to minimise the risk of contact of the heat exchanging fluids one with the other and in which there is a considerable temperature difference between the heat exchanging fluids. According to the invention the inner component tubes 36 project beyond the outer component tubes 38 and the inner and outer component tubes are supported in separate tube plates spaced one from the other, one of which is thinner than the other and is rigidly connected to the thicker tube plate. Preferably the space between the tube plates forms a chamber for the collection of leakage fluid. In the form shown the inner component tubes 36 of the "leak-proof" tubes are secured in the thicker tube plate 18 and the outer compartment tubes are secured in the thinner tube plate 42 which is supported in spaced relation to the plate 18 by a ring 44 defining with the plates, a space 46 for leakage fluid which is removed from the leakage space through a passage 48 formed in the thick plate 18. Alternatively (Fig. 1 not shown) the outer component tubes may be supported in the thick plate 18 whilst the inner tubes are supported in the thin plate 42. When the tube assembly is positioned within the shell 10, the thick tube plate 18 is sandwiched between the flanges of the shell and header 12. Straight tubes extending between headers or U-tubes may be employed. Specifications 703,081 and 728,131 are referred to.

Title: Improvements relating to telephone and signalling systems
IPC: H04M5/04
Filed: 1927-10-12
Abstract: 301,597. Siemens Bros. & Co., Ltd., and Christian, D. A. Oct. 12, 1927. Central station apparatus.-In telephone &c. systems in which the next idle outlet is indicated to an operator by means of a hunting switch, the switch has access to only a portion of the outlets corresponding to a particular direction, the connections of the outlets to the switch banks of a group of operators being graded and so arranged that different switches have access to different outlets. All the outlets of a group are multipled before each operator and if the outlets to which the switch has access are all busy the operator tests the remaining outlets with the tip of a plug in the usual way. In an example, 50 junctions of a group are multipled before 10 operators. Each switch has access to 15 junctions of which the first two are individual to a position, the next three are common in two positions, the next five common to five positions, and the remaining five common to the whole ten positions. The Figure shows one such position for an operator at a manual telephone exchange extending calls to automatic exchanges. Fifteen of the junctions leading to one exchange are associated with the first fifteen contacts of the switch 1 - - 4 and the remainder of the bank is associated with junctions leading to a second automatic exchange. If a junction to the first exchange is desired, key K<1> is depressed energizing relays L', R. The stepping magnet DM operates over wiper 1 until an idle junction is reached when relay T operates, marks the junction temporarily busy to other operators' switches and lights a lamp JL individual to the junction selected. When the operator plugs in, relay E marks the junction permanently busy and key K' is then released and the switch restores to normal. If all the fifteen junctions are busy, relay T energizes in position 16 of the switch and lights a special lamp JE. If a junction to the second exchange is required the operation of key K<2> energizes relay L<2> to render the second group selectable, the earth at the back contact l1 causing the wipers to pass over the while of the first group. The invention is also applicable to telegraph concentrator arrangements.

Filed: 1970-06-08
Abstract: 1316633 Flash exposure control ASAHI KOGAKLIKOGYO KK 8 June 1970 [6 June 1969] 27673/70 Heading G2A A camera has an automatic exposure control arrangement which prior to shutter opening generates a preparatory light flash and memorises the resulting intensity of light reflected from the object, and which generates a main light flash when the shutter is open, the memorized light intensity controlling either the duration of the main light flash or the time for which the shutter is open. In the circuit shown, a high voltage is connected to point A and a low voltage is connected to point B. The energy stored in capacitor 3 is used to generate the preparatory light flash from discharge tube 1, the light intensity reflected from the subject illuminating photo-conductor 9 which applies an electric signal to an integrating capacitor 11 and is stored thereon. Upon shutter initiation a timing circuit containing a capacitor 16 begins operation, after opening of contacts 15, under control of the memorized information so that after the lapse of a time determined by the memorized information a trigger circuit 17 is switched to energize a short circuit discharge tube 20. The main light flash is generated by the energy stored in capacitor 2. Switches 28, 29 and 30 are operated by an electromagnet 27 upon shutter release. The photo-conductor is preferably positioned to receive light through a pentaprism viewfinder of a single lens reflex camera. A variable resistor 31 is adjusted according to the set diaphragm aperture and film speed. The theory of operation is given in which the effect of ambient illumination in addition to the preparatory light flash is considered.

Filed: 1971-06-14
Abstract: 1387823 Character recognition systems MEL EQUIPMENT CO Ltd 15 March 1972 [14 June 1971] 27679/71 Heading G4R A character is recognized by apparatus which compares the character with binary reference masks simulated by logic circuits. Elementary areas of a mask corresponding to areas of the reference character are linked together in overlapping pairs by the logic. A group of such areas represents, for example, a stroke element of the character and is identified as being present in the unknown character if at least one area of each of the pairs in the group coincides with the unknown character. The character is scanned by a raster-type scanner or by relative movement between a sequentially enabled column of photo-cells and the characters. The serial signals from the scanner are converted to binary form in which each bit represents the black/white state of a corresponding elementary area of a notional matrix M superimposed on the character. The signals are shifted through a shift register, Fig. 4 (not shown), having as many stages as there are areas. In one arrangement groups of overlapping pairs of adjacent stages are connected to OR gates feeding an AND gate, e.g. Fig. 2 (not shown), each group of stages corresponding to a stroke element of a reference character. For example, for the reference character H shown in Fig. 1a, the areas 1-8 form one group, 10-17 another group, and 19-22 a third group, the areas being considered in pairs as indicated in Fig. 1b. A similar set of groups is selected for each reference character. Each gating assembly determines whether the pairs of adjacent areas, e.g. 1, 2, of a group have at least one 1-bit state, i.e. black state, so that if no two adjacent areas are both white in any group of the set a signal indicating the corresponding character is generated. Reference is made to an alternative form of gating logic in which, for example, the areas 20, 21; 21, 19; 19, 22 are respectively compared. Further, each set of groups may be associated with groups of areas that should be white for the corresponding character, and if any such area is found to be black identification of the character is inhibited even if the logic units otherwise would have identified it.
