Title: Cine cameras
IPC: G03B19/26
Filed: 1972-09-25
Abstract: 1395731 Cinematography AGFA-GEVAERT AG 25 Sept 1972 [24 Sept 1971] 44241/72 Heading G2E In a cine camera a mechanism is provided which arrests film transport in response to the completion of a fade-out. The fade-out may be produced by electronic control of the lens aperture or the shutter opening. The circuit shown includes an aperture control 1, a Schmitt trigger 2 and a film drive motor control 3. To commence filming switch 5 is closed. Photo-resistor 36, rheostat 37 and galvanometer 29 are thus energized; the galvanometer 29, whose reading is proportional to light incident on the photo-resistor 36, setting the camera lens aperture (by a mechanism not shown). Closing switch 13, next, discharges capacitor 15 to power the amplifier defined by transistors 9,10. The electromagnet 8 is thereby energized to close switch 7 to energize film drive motor 4. To produce a fade-out switch 33 is closed. This causes the potential on the negative side of capacitor 35 so switching on transistor 28. An increased current may therefore pass through the galvanometer 29 via the additional path of rectifier 30, transistor 28 and resistor 28a. This increased current causes the lens aperture to close. This increased current path causes a control voltage to be transmitted to the base of transistor 17a. This switches on transistor 17a so lowering the potential at the base of the transistor 17 that it switches off. Thus the potential at the collector of the transistor 17 rises and this positive voltage pulse raises the potential of the base of transistor 10 to switch off the amplifier so causing the switch 7 to open and the motor 4 to stop. The stopping of the motor 4 after the fade-out is determined by the rate of discharge of the capacitor 35 which thus controls the rise in potential of the base of transistor 28. To produce a fade-in the switch 33 is closed (or kept closed after fade-out) to ensure that the aperture of the lens is closed. The motor 4 is then switched on by opening switch 13 to permit the capacitor 15 to charge and closing the switch 13 to use the charge to switch on the amplifier to close the switch 7. Switch 33 is then opened, this causes capacitor 35 to charge, thus the transistor 28 slowly switches off and the galvanometer current is reduced causing the lens aperture to increase. The Schmitt trigger 2 is returned to its original state with the transistor 17 on and transistor 17a off. Dissolves may be produced if the camera can rewind the film between fade-out and fade-in.

Title: Production of a callikrein inactivator from insulin wastes
IPC: A61K38/22
Filed: 1962-12-06
Abstract: The callikrein inactivator is isolated from the waste fractions obtained during the production of insulin from the pancreas of animals, e.g. cattle and pigs, by known methods for the isolation of callikrein inactivator from extracts of animal organs containing the callikrein inactivator.  These waste fractions are (a) the precipitate formed by neutralization of the acidic alcoholic pancreas extract, e.g. with ammonia to pH 7 to 8 and (b) the mother liquor remaining after the separation of crude insulin from the aqueous solution with 20 to 25% of sodium chloride.  The precipitate of (a) may be extracted with aqueous methanol containing calcium chloride or manganous chloride, separating the extract and precipitating the callikrein inactivator by acetone in the presence of kieselguhr. After washing with acetone, the callikrein inactivator is extracted with water and may be further purified by precipitating waste proteins by sulphosulphosalicylic acid, followed by removal of excess precipitating agent by ion exchanger.  Specifications 783,316, 886,989 and 916,932 are referred to.

Title: Monitoring the Transmission of Digital Data
IPC: G06F11/00
Filed: 1968-09-27
Abstract: 1,188,228. Digital transmission systems. SIEMENS A.G. 27 Sept., 1968 [28 Sept., 1967], No. 46158/68. Heading H4P. [Also in Division G4] A process for testing a transmission path comprises transmitting data through the path, the data comprising a word having free bitlocations. A predetermined one of the free bit-locations is supplied with a parity bit. At least one check unit downstream of that supply checks the word on the basis of the parity bit and produces a further parity bit which is entered into a further free bit-location of the word. Devices 1 such as analog/digital converters or pulse counters supply data to an input device 2. The data can be supplied with a parity bit or have one supplied at the input device. A check unit 6 is used to check the word against the parity bit and to insert a further bit to maintain the parity, the further bit being introduced into a predetermined location. The data is then passed, via multiplexors and decoders if required, to a device controlling data input to a computer 5. One or more further monitoring circuits 7 check the parity of the word and each inserts a further parity bit in predetermined locations. The transmitted word is stored in the computer. The parity bits show whether a fault has occurred and in which section of transmission path it occurred. By transmitting further words for comparison it is determined whether the fault is temporary or requires replacement of circuitry. More complicated codes than a simple parity bit can be used.
