Patent FR-2234423-A1 (FR)
Title: Road or bridge surface heating control - uses computer processing temp. and moisture readings of surface or air state and air velocity
IPC: G05D27/02
Filed: 1974-06-17
Abstract: An electric heating system for road surfaces, bridges or other sections, where black ice may be formed, is so controlled that the power consumption is reduced to a minimum, by measuring all environmental factors and switching on the preheating only if under the geographical conditions a black ice formation is possible. Temperature probes are provided for the ambient and the surface temperature, and an anemometer for the wind velocity. Differentiators sense any rapid changes. A computer receives their outputs together with those of moisture meters for the surface and the air. A switch cuts in the heaters only if black ice can be expected.

Patent FR-2297662-A1 (FR)
Title: Control circuit for the operating cycle of a filter - initiates auxiliary operations by optimising the average output over regulated time period
IPC: B01D37/04
Filed: 1975-01-14
Abstract: The flow of filtrate through a filter is measured and the flow is integrated. A separate integrator relays the time taken for the filtration to a summator where the time for an auxiliary operation, e.g. removal of filter cake, is added. The sum of these 2 is fed to a dividing unit in which the integrated flow is divided by the time summated to give an output which is the average output flow. This signal is monitored by an optimiser which, when the average output reaches its maximal average value, initiates a signal to a controller that stops the filtration and begins one or more auxiliary operations. At the same time this controller returns the 2 integrators to their initial position before the cycle commenced. Each control block formulates one criterion for initiation of an auxiliary operation. In the case where there are a number of control groups in sequence each setting criteria for initiating different auxiliary operations the control groups are connected to the optimising component and to all the other groups in such a way that at the time of operation of a control group all the preceding groups are returned to the initial position and all consecutive groups cut the signal coming from the particular group. The system is used for filters where continuous operation is interrupted by auxiliary operations, e.g. removing of filter cake when filtering a liq. containing sediment that builds up on the filter cloth and ensures the max. average output of the filter in the case of changes in its working conditions.

Title: Aluminium case for moulding and preserving fruit jellies - avoiding lifting and candying and allowing longer preservation
IPC: A23L21/12
Filed: 1975-02-27
Abstract: Fruit jellies are produced in a smooth or corrugated aluminium case which serves as a mould, preserving means, and presentation means for the jelly and which can be easily removed prior to consumption of the jelly. The aluminium case can be filled with the jelly by means of a pourer of the 'Mogul' type, and the jelly can be sprinkled with crystallised or other sugar to give it its final appearance. The process can be used for any preserve which is cast in a mould and of which the preservation properties are affected by air, and eliminates the conventional operations of lifting from the mould and candying, and guarantees preservation for a much longer period and presentation without further handling.

Title: Autoclave construction and operation - incorporating construction by bolting together shells and end-plates, automatic programming and fluid recycle
IPC: B01J3/00
Filed: 1975-05-21
Abstract: Constructing and operating autoclaves and steam generators includes the construction of autoclaves from concentric shells and plates, programming the operation of autoclaves, controlling the flow of operating fluids and the provision of a condenser and condensate collector. Concentric shells are fitted into rabbets machined in plates, fitted with O rings in e.g. silicone, to ensure longitudinal fluid-tightness. One plate forms the end of the autoclave, the other carries the door. The space between the shells receives the heating medium, e.g. steam. The operation of centrifuges is programmed and the flow of operating fluids is controlled by a shaft driven by a motor so as to make one revolution per operating cycle. The shaft carries a cam to operate the door and a cam which pinches flexible tubes of e.g. silicone, which carry the fluids, at the required times for operation. The condenser and condensate receiver allows a boiler which supplies steam to e.g. an autoclave to be put under vacuum by cooling at the end of an operating period, and to be refilled with water by suction from the condensate specifically. Provides means autoclaves construction specifically for partic. uses, automatically controlling the operating cycle and permanently recycling water used in a boiler supplying heat to an autoclave.

Title: Scintillation counter for beta and gamma radiation - is large phosphorus crystal with lined recess for sample vessel
IPC: G01T1/202
Filed: 1975-06-30
Abstract: A scintillation device comprises a scintillating counting chamber of inorganic phosphorus in crystalline from; the scintillation block is elongated and has a depression to receive a sample vessel; this depression is lined with a highly transparent substance, the refractive index of the phosphorus, of the lining and of the sampling vessel being all approximately the same; the lining is highly transparent and has a low photon absorption capability of less than 20% for wave-lengths in the range 3500-4200 angstroms and completely seals the phosphorus surface adjacent to it. The sample vessel fits neatly into this lining and is also of highly transparent material; a seal couples together the three surfaces and also has a similar refractive index. The entire surface of the phosphorus is coated with a material which reflects photons in wave-lengths of the same range as above, so that photons generated in the sample are transmitted into the crystal and are not emitted from it. The inorganic phosphorus and the photodector surface is surrounded by a metal housing having a door for insertion of the sample flask; an electronic circuit receives and summates pulse signals from the photodetector and amplifies the summated signals to give a predetermined amplitude difference and to analyse the signal.

Title: Selectively dismantling first plate from plate stack of filter press - by incorporating carriages for sepg. first plate from stack and holding subsequent plate, giving easy handling of large heavy plates
IPC: B01D25/172
Filed: 1977-03-09
Abstract: System incorporates two dismantling carriages and two locking carriages. Each dismantling carriage has a driving finger which can be put out of action, and a resettable stop finger. A mechanism connecting the fingers can bring about the projection of the driving finger and the lowering of the stop finger, and then the projection of the stop finger and the lowering of the driving finger. A bistable mechanism holds the stop finger in position. The locking carriage has a hook for holding the subsequent plate and a catch which can prevent the carriage from moving back. The hook can be out of action. Problems associated with handling large heavy plates which run on wheels, are avoided. The system is simple and reliable and has few components. It allows only the plate at the head to be sepd. from a stack of loaded plates, drawn away from the subsequent plate, stopped, and then drawn to the end of the frame.
