Patent GB-272167-A (GB)
Title: Improvements in or relating to apparatus for electrically transmitting images or pictures
IPC: H04N1/36
Filed: 1927-02-01
Abstract: 272,167. Siemens &. Halske Akt.-Ges. June 1, 1926, [Convention date]. Copying-telegraphs.-In order that it may be possible to change the picture-carrying drum at the transmitting or receiving station of a copying- telegraph without interrupting the synchronism, the disc c. Fig. 1, of a magnetic or other non- positive clutch is driven continuously from the motor m which is synchronous with the motor at the distant station, while the removable picture drum t is driven from the other member c<11> of the clutch. The member c is controlled by a brake spring i to prevent backlash and carries a cone n on to which the drum t fits in a position rendered definite by the provision on the cone of a vertical groove adapted to engage a pin on the drum, which is held down by a screw o. When the drum has been changed it is run up to speed by the non-positive action of the clutch, and on the attainment of the required speed the centrifugal arm e engages the projection c<1> on the disc c and converts the drive into a positive one, so as to ensure correctness of phase. The drum at the transmitting end revolves without axial motion, a pencil of light from a source p, Fig. 2, being projected on to the drum by a mirror q which is traversed axially by a screw. The receiver drum t mav be loaded with film in a darkroom and enclosed in a light-tight casing having a slot which can be uncovered, when the drum is in position, for the purpose of admitting light. Synchronous movements and synchronism indicators.-The phase of the shaft a, Fig. 1, is corrected by manual adjustment of the differential gear h, or by turning the stator of the motor m. Synchronism is indicated by the following means : a bright or dark patch u, Fig. 2, on the transmitter drum affects a light-sensitive device q at each revolution and sends an impulse through the line v to the light valve j at the receiving station. If an impulse is received when the mirror z is in phase with the patch u, but not otherwise, a flash is seen at E. Alternatively the receiver drum may cause a lamp to flash at the completion of every revolution, for comparison with flashes controlled from the transmitter. In a modification the disc c is driven through a shaft which contains a freewheel clutch and is arranged in parallel with the shaft a. No power is then normally conveyed through the differential gear, but when the control h is moved in one direction the free-wheel clutch in the parallel shaft, enables the phase adjustment to be taken up.

Abstract: 950,375. Determining cloud points. BRITISH PETROLEUM CO. Ltd., and P. G. HOLBOURNE. Jan. 4,1963 [Feb. 5,1962], No. 4358/62. Headings G1A and G1D. The cloud point of a hydrocarbon oil is determined by passing it through a drying means 13 to a measuring cell 11, directing a beam of light from source 17 through the oil to a reflecting surface 19, cooling the oil such as by a thermoelectric cooler 24 and measuring the temperature, such as by thermocouple 25, when the intensity of the beam of light from the surface 19 decreases a predetermined amount. A reference cell 12 may be arranged to contain the same oil at ambient temperature and a beam of light of the same intensity as the first one is passed from source 17 through the oil to be reflected at 21, the two reflected beams being received by photo-electric cells 22, 23 arranged in a bridge circuit which is balanced at ambient temperatures. When the bridge becomes unbalanced to a sufficient extent, the degree of unbalance being adjustable so that pour point or cloud point may be determined, the pour point normally being about 6C. lower than the cloud point, a relay is actuated which causes thermocouple 25 to operate a recorder and a second relay to be operated and held for about a minute so that cooler 24 is switched off and valve 16 opened. The tested oil thus flows out of the system and a fresh sample flows in. The chamber 10 may be evacuated.
