Title: Starting and stopping device for sound motion picture camera
IPC: G03B19/18
Filed: 1974-07-30
Abstract: 1435240 Film transport mechanism BELL & HOWELL JAPAN Ltd 30 July 1974 [31 July 1973] 33541/74 Heading G2E A motion picture camera in which the film is transported intermittently through an exposure station 16 and continuously through a sound recording station 20 by separate motors, has means movable between a camera operative and camera inoperative position, which brings film transporting means at station 20 into or out of action, and energizes and de-energizes the motors. As shown, the operating means comprises a button 68 supported on a slide 60, which can be pushed in direction A to start the camera operating, and in direction B to stop it. Slide 60 is linked to an arm 48 by a spring 54, which has one end fixed to arm 48 and the other end engaged in a slot 56. On arm 48 is mounted a backing pad 46 and a pressure roller 42, which can hold the film against the magnetic recording head 32 and a drive capstan 30 respectively. Also mounted on arm 48 is a sensor 94 which is spring-urged into contact with the loop formed by the film 14 between the exposure and recording stations, and serves to maintain the size of this loop constant. Arm 48 also carries two trigger members 74, 76 which can engage and pivot a lever 80 into one of two positions. As slide 60 moves in direction B, arm 48 is pivoted anticlockwise, so that the film is brought into operative contact with the recording head and drive capstan. Shortly afterwards lever 80 is pivoted clockwise into the full line position seen in Fig. 2. This drives, through an over centre spring 86, a contact plate 88 into engagement with a fixed contact 92 which energizes the two drive motors. When slide 60 is moved in the reverse direction, spring 54 and hence arm 48 are pivoted clockwise, so that the film is released from engagement with head 32 and capstan 30. Shortly afterwards trigger 76 engages and pivots lever 80 clockwise into the broken line position of Fig. 2. Hence plate 88 is driven out of engagement with contact 92, and so the drive motors are stopped.

Patent GB-418274-A (GB)
Title: Improvements in or relating to active carbon
IPC: C01B31/08
Filed: 1932-11-29
Abstract: The deleterious effect on active carbon of the impregnation by a chemical agent is minimized or prevented by using during the activation the reagent, or an equivalent substance, with which it is proposed to impregnate the activated carbon.  The same result is attained by effecting a second heat activation after the impregnation.  Impregnation may be effected by another body which during activation will yield the desired compound, e.g. a salt the decomposition or reduction of which will leave an oxide; the salt may be applied in solution.  An example is given of impregnation by caustic soda or potash or both, the impregnated carbon being dried and heated to 600 to 700 DEG  C.  After being cooled, the carbon is moistened by spraying with water or by the passage of steam. Sodium or potassium carbonate may be formed during the operation or may be added to the impregnating liquid.  The carbon so prepared is particularly efficacious in the treatment of phosgene.

Title: Method of manufacturing decolorising carbon
IPC: C01B31/12
Filed: 1930-11-12
Abstract: In the manufacture of decolourizing carbon, wood or other carbonaceous material is mixed with calcium hydroxide and carbonized by dry distillation; the calcium oxide is then slaked and removed as calcium saccharate by treatment with a solution of sugar.  In an example, chips of Japanese cypress are mixed intimately with 50-100 per cent of milk of lime, dried and heated in a retort with exclusion of air at 800-1000 DEG  C. for four to six hours.  The mass is then stirred in air for two or three minutes to ignite part of the carbon, and heated in known manner to activate it and to convert all the hydrate to lime, after which it is transferred to a closed vessel where it is cooled and pulverized.  Hot water is then added to slake the lime and the mass is then treated with a 50 per cent solution of sugar at 50 DEG  C., after which it is filtered from the solution of calcium saccharate formed, washed with water and dried.  Any small amount of lime remaining can be removed with hydrochloric acid.  The calcium saccharate may be employed instead of lime in the carbonation or sulphitation process in the purification of sugar.ALSO:In the manufacture of decolourizing carbon, wood or other carbonaceous material is mixed with calcium hydroxide and carbonized by dry distillation; the calcium oxide is then slaked and removed as calcium saccharate by treatment with a solution of sugar.

Title: Data storage apparatus
IPC: G06F11/14
Filed: 1971-07-23
Abstract: 1340220 Error detection/correction INTERNATIONAL BUSINESS MACHINES CORP 23 July 1971 [23 July 1970] 34618/71 Heading G4C A digital data storage system includes an error detection means operable to read out a previously stored word and generate an error signal if the word was incorrectly stored, a means being provided responsive to the error signal for inverting all the bits of the read out word and entering it into the location from which it was read in inverted form together with a marker bit indicating that the word is stored in inverted form. In the preferred embodiment the memory 1 is a monolithic integrated circuit store storing words which contain an even number of bits including data bits, a parity bit, and the marker bit. In operation a word to be stored is fed from a source 5 to the store inputs 10 via AND gates 7. The word is then read out and stored in register 14. The read out word is then tested for errors by parity checking circuits (not described) and/ or by comparison with the input word. If an error is detected a signal is passed to flip-flop 21 via AND gate 19. The output of the flip-flop passes to AND gate 23b which conducts when a "write back" signal occurs and passes a signal to the exclusive-OR gates 9 causing the word read from the store and held in register 14 to be written back in inverted form. The signal from the AND gate 23b is fed to the store in a marker bit location to indicate that the contents of the associated word location are in inverted form. The combination of the inverted erroneous word and a consistently defective storage location result in the complement of the word without errors being read out. The inverted word in the store may be checked using the same procedure, an error causing a "stop" signal to be passed to an associated data processing system 18 instead of another inversion being made. On read out the marker bit is read into stage 14d of the output register and is applied to gate 23a causing a signal to be passed to the exclusive-OR gates 9 which invert the word as it is read out and before it passes to the associated data processor 18.

Title: Improvements in and relating to the production of oil gas
IPC: C10G9/38
Filed: 1922-12-19
Abstract: 217,613. Hackford, J. E. Dec. 19, 1922. Oil gas.-In the generation of oil gas by partial internal combustion, the rear end of the combustion initiation region is situated close to the burner nozzle which is maintained at such a temperature as to avoid deposition in the combustion chamber. A chamber comprising an inner barrel m, Fig. 6, of refractory material and having outlets u is provided within a casing b, and' the air and oil is supplied to the burner nozzle d, which projects into the barrel m, through tubes f, e respectively. A flame t is produced in the barrel m by partial combustion, of which the area s bounded by the envelope 2 represents the mixture of unburnt oil and air at a temperature of about 200‹ C. while the envelopes 2 represents the combustion initiation region which together with the area s<1> is maintained at about 600‹ C. by the flame t sweeping through the ports u and over the barrel m to an outlet therein. To ensure satisfactory operation the envelope 2 should not contact with the interior of the barrel m or extend through the gas outlet j. The chamber is initially heated electrically or by charcoal &c., while when the output of gas falls below that necessary to maintain the temperature condition within the chamber the fuel is completely burned and the products of combustion are diverted from the normal gas outlet. Thermostatic or pyrometric apparatus may be provided to maintain constancy of working conditions with varying output by regulating the proportions of fuel and air. In modifications, the barrel m is dispensed with and the hot products are caused to return and sweep over the burner or the exterior of a sheath or partition within which the combustion initiation region is situated.
