Filed: 1984-11-28
Abstract: In a camera having automatic shutter control dependent on sensed illumination and film speed sensed as coded information on a film container, the coded information being in the form of five areas each having two alternative speed-indicating conditions (conducting and insulating), the shutter-opening time is determined in an approximate manner by the comparison in a comparator AC of a time-varying voltage with a reference voltage, the time-varying voltage having a rate of rise dependent on the illumination level measured by a photosensor PC and on the condition of the second area (A2, Figure 2) as sensed by probe P2 to provide two alternative time-varying voltages for each illumination value and the reference voltage being dependent on the condition of the third and fourth areas (A3 and A4) as sensed by probes P3 and P4 to provide three alternative reference voltages, a total of six alternative comparisons thereby being provided each being for a different film-speed setting (from 32-1000 ISO; see Table II). The photosensor is of non-linear type, eg a cadmium sulphide cell. <IMAGE>

Title: Method and device for temperature supervision
Inventor: WESTERGARD RUNE
IPC: B60C23/20
Filed: 1985-03-07
Abstract: The invention relates to a method and a device for monitoring the temperature of a moving member (e.g. a bearing) (3), by means of a signal generated when the temperature of the member exceeds a certain limiting control temperature. The signal is conducted to a central supervisory unit supervising the operation of the moving member. In thermal contact with the moving member (3) is located a thermal release device (10-13) which trips when the temperature exceeds the control temperature. Close to the path of motion of the member a sensing means (4) is disposed, this means (4) sensing when the thermal release device (10-13) has tripped and transmits a signal indicating this to the central supervisory unit. The thermal release device may be a bimetal strip or comprise a memory metal, or alternatively it may incorporate solder which melts to release as indicator which is then moved by a spring or small explosive charge. <IMAGE>

Title: Metal-containing cellulose matrix
Inventor: GADD KENNETH FREDERICK
IPC: C08K3/08
Filed: 1986-04-03
Abstract: A cellulose matrix which has distributed therethrough atoms of a metal which can form kinetically labile ions (e.g. copper (0)) may be prepared by reducing a complex comprising kinetically labile metal ions held within a deprotonated cellulose network. This complex may in its turn be prepared by dissolving cellulose in a solvent containing the kinetically labile metal ions (e.g. cuprammonium or copper/1,3-diaminopropane) and contacting the solution formed with alkali. The metal atoms in the cellulose matrix may themselves be replaced by atoms of metals lower in the electrochemical series e.g. silver, platinum, palladium. Moreover the cellulose matrix material may be charred to give a carbon matrix which has distributed therethrough atoms of the corresponding metal.

Title: Apparatus for measuring an external parameter
Inventor: THEOCHAROUS EVANGELOS
IPC: G08C23/06
Filed: 1986-10-20
Abstract: An optical fibre apparatus measures an external parameter, e.g. temperature, at any of a number of different locations using time-domain reflectometry techniques. Sensor devices 30, 31 each comprising a chip or plate of ruby glass, are interconnected by optical fibers 32, 33. A laser 50 launches along the fibre string short pulses of light at a first wavelength on the absorption edge of the ruby glass and a second wavelength in the transmission region away from the edge. A timer 55 controls sampling circuits 58, 59 to measure back scattered energy at each wavelength at spaced times corresponding to spaced points 62, 63 along the fibre on opposite sides of a selected sensor device 31. A processor 64 calculates the absorption loss in the sensor device at each wavelength by comparing the back scattered energy from the two points on opposite sides of the device, and calculates the differential absorption loss by comparing the losses at the two wavelengths. Instead of using discrete sensors, a single optical fibre, having a spectral absorption profile, may be provided to constitute both the interconnecting optical fibre and the sensing devices. Materials other than ruby glass may be utilized. <IMAGE>
