Title: Simplified automatic SLR camera - has digital storage of exposure reading and digital/analogue convertors
IPC: G03B7/093
Filed: 1974-12-11
Abstract: Conventional SLR cameras with automatic exposure control store the exposure reading in a digital form as a series of impulses. This requires a decoding counter and an exclusive OR gate to process the stored information. A much simpler system is obtained if the exposure reading is passed through a digital analogue converter for storage, with the analogue signal being compared with the preset exposure factors. When used for exposure the signal is converted back into an analogue signal for a simple comparison with the preset values and with a subsequent simpler exposure control. The control is independent of variations in temperature.

Title: Multiple treatment machine for leather trade - for fleshing and cleaning and other operations by changing rollers
IPC: C14B17/06
Filed: 1974-11-27
Abstract: Multiple treatment machine is for treating skins and leather and changes in the type of operation are made by changing the tool whilst the driving system for the skins remains the same. In a machine in which, after fleshing the hides, the impurities are removed from the wool by a washing process, the operator spreads the skins over a carrier roller with the wool side downwards. This roller can oscillate between a charging position and a running position by press. on a pedal. In the latter position, the skin is between the carrier roller and a driving roller, which rotates in the anticlockwise direction; at the same time the skin is applied against a fleshing roller (I) and any pieces of flesh are removed. The skin passes between rollers to a second carrier roller which is applied against a second fleshing roller (II) which completes the process. The skin is tasken to a cleaning roller (III) where washing is effected between this and a carrier and driving roller; the skin having been turned over so that the wool side is offered to the cleaning roller. The skin is then evacuated from the machine. Other operations can be effected on the same machine by replacing rollers (I), (II) and (III) by other appropriate rollers.

Patent FR-2276625-A1 (FR)
Inventor: DORAN SAMUEL
IPC: E01C11/26
Filed: 1975-05-09
Abstract: A beam of charged particles is deflected in a closed path such as a square, for example, over a cross wire grid at a constant velocity by an X Y deflection system. A small high frequency jitter is added at both axes of deflection to cause oscillation of the beam at 45 DEG to the X and Y axes. From the time that the leading edge of the oscillating beam passes over the wire until the trailing edge of the beam passes over the wire, an envelope of the oscillations produced by the jitter is obtained. A second envelope is obtained when the leading edge of the beam exits from being over the wire until the trailing edge of the beam ceases to be over the wire. Thus, a pair of envelopes is produced as the beam passes over each wire of the grid. The number of pulses exceeding ten per cent of the peak voltage in the eight envelopes produced by the beam completing a cycle in its closed path around the grid are counted and compared with those counted during the previous cycle of the beam moving in its closed path over the grid. As the number of pulses decreases, the quality of the focus of the beam increases so that correction signals are applied to the focus coil in accordance with whether the number of pulses is increasing or decreasing.

Title: Screen of rotating rollers for cleaning beets - with associated helicoidal springs and blades around peripheries
Inventor: CHEVALIER EMILE
IPC: A23N12/00
Filed: 1976-06-21
Abstract: Portable screen, for the cleaning of beets, consists of a series of parallel, rotating rollers with horizontal axes placed side by side between side-plates. Each roller has two types of rod which alternate arounds its periphery one consisting of a helicoidal spring, stretched between the side-plates, and the other a balde which is fixed in the side plate by elastic means, e.g. rubber blocks. The sieve is mounted on a wheeled chassis having a feed hopper with an extractor. A conveyor belt evacuates the earth and foreign matter falling through the sieve. The latter also acts as a conveyor which bring the cleaned beets to the outlet chute. In operation, the rubbing of the beets on the springs and the blades detaches the earth which passes through the rollers. Stones or other heavy objects can pass between the rollers by displacing the springs and the blades towards the axes of the rollers. The screen is more efficient than known screens of this type and obviates the risk of damaging the beets.
