Title: Turbo superchargers
Inventor: KELLETT ERIC
IPC: F01D9/02
Filed: 1969-06-27
Abstract: 1,263,932. Turbine casings. C.A.V. Ltd. June 27, 1969, No.32595. Heading F1T. The turbine casing 17 of an exhaust gas driven turbo-supercharger unit for an internal combustion engine comprises a pair of separately formed annular casing portions 23, 24 separated by a dividing plate 25 to define axially spaced passages 20, 21 for the supply of exhaust gas from respective cylinder banks of the engine to the turbine rotor 16. The passage 20 is formed by a channel 26 in casing portion 23, the channel having an initial tangential portion of substantially constant cross-section which merges into a circumferentially extending portion of decreasing cross-section. Passage 21 is similarly formed by a channel 27 in casing portion 24 but has a greater circumferential length than passage 20. The dividing plate 25 is generally flat but is deformed at 28a, 28b to provide pairs of alternate arcuate openings on to the periphery of the turbine rotor 16 from channels 26, 27 respectively. The deformed portions 28a, b are connected by tangential webs 29. The casing portions 23, 24 and plate 25 may be formed from sheet metal pressings which are then welded together to form the complete casing 17. Alternatively they may be formed from ceramic material, such as silicon nitride, shaped by pressing in a mould or spraying on a detachable former, the portions then being joined together using a nitriding process. The complete casing 17 is secured to a turbine outlet duct 19 and to the body 10 of the turbosupercharger unit by studs 30. The turbine 16 drives the supercharging compressor 13 through a shaft 11.

Patent GB-1007919-A (GB)
Title: Character reading apparatus
IPC: G06K9/03
Filed: 1964-08-11
Abstract: 1,007,919. Automatic character reading. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1964 [Aug. 13, 1963], No. 32650/64. Heading G4R. In a character reading system, if the reader is unable to read a character the image of the character is displayed at an operator station, the operator having a keyboard to signal the identity of the character and means are provided for inserting the character in its proper position in a sequence of characters. Coder 26 receives character identification signals either from the reader 3 over cable 2 or from the operator stations 4, 5, 6. Selector 10 couples the reader 3 to one of the stations 4-6 via cable 12. When the reader fails to recognize a character a reject signal is produced on line 16. Another signal on line 18, indicating that a new character has been sensed and either read or rejected, passes to address counter 20 which numbers them successively. The numbers pass to address register 24 to select the location in buffer 8 where the signal is to be stored. The coder 26 changes the signal on cable 2, e.g. a marking on one out of ten leads, to a combination of marks on four leads. The address counter passes an output on cable 34 to the stations 4-6 where it is stored so that if the character reader fails to recognize a character the corresponding address is passed via cable 35 to address register 24 so as to determine the location where the rejected character identification is to be stored, when this data is available. By this means the character which produced the reject signal, is stored in buffer store 8 in the correct position in the sequence. Operator sequence-The selector 10 energizes a lead 36, Fig. 2, in the selected station 4-6 to enable gates 38, 39, 40, 41. The address counter outputs are continuously gated to a register 46 until a reject signal appears. This causes the next station to be selected and de-energizes lead 36. The address then in register 46 is that of the rejected character. The video and deflection signals from the character reader are likewise gated to a storatron which displays the visual image of the character rejected. The keyboard 52 is set by the operator in accordance with the character displayed. The identification signal is passed by gate 56 to the coder 26 at a time when the reader is not providing a signal to the coder 26. This is effected by using the signal on lead 18 indicated that a new character has been presented to the reader. The keyboard stores the character set, trigger 96 being set by a signal on line 94. Gate 100 passes the signal at the appropriate time, resetting trigger 96 and opening gates 56 and 60 to pass the, character identification from the keyboard and the corresponding address from register .46.
