Patent FR-2228604-A1 (FR)
Title: Applying resin coating to fibres or particles - by turbulent impact with a high velocity spray
IPC: B27N1/02
Filed: 1973-05-11
Abstract: fibres or other relatively small particles are dispersed at a controlled rate to fall into a small chamber contg. a turbine type atomiser generating a horizontal radial high velocity spray of a resin coating soln. The spray droplets impact the target fibres etc. under turbulent conditions in a carrier fluid (air) drawn down through the chamber by an aspirator feeding from the base of the chamber. The fibre feed system comprises a two stage hopper discharging via an Archimedean screw. A conical baffle in the chamber deflects the falling particles beyond the rim of the spray turbine. Esp. used for coating fibres to be consolidated into medium density particle board or panels. Impregnation of individual fibres which are subsequently bulked together produces more uniform coatings and requires low overall resin loadings for a required panel strength than impregnation of pre-compressed or woven fibres. Removal of volatile solvent is also relatively prompt and complete.
Patent FR-2257508-A1 (FR)
Title: Overhead cable conveyor saddle - has compression springs to absorb shocks caused by passing over pulleys

Title: Monitoring device for electric cct. in vehicle - has transformer with primary winding in monitored cct.
IPC: G01R31/00
Filed: 1973-09-20
Abstract: The secondary winding has an earthed centre tapping, and both ends are connected to a diode and a smoothing capacitor. Voltages appearing across the capacitors are applied to the inputs of a bistable trigger, tripped into its "1" state when the circuit is switched on, and then tripped back into its "0" state by switching-on pulses induced by the secondary circuit. Circuit interruption generates in the secondary winding a disconnection pulse which trips the trigger into its "1" state. Load resistor of one of the trigger transistors is in the form of a signalling lamp showing the circuit disconnection; or the trigger "1" output controls a lamp signalling the circuit interruption.
Patent FR-2245576-A1 (FR)
Title: Solar still - including concentrically mounted evaporator and condenser tubes

Title: Transferring photographic images - by adhering to transfer sheet then detaching support
IPC: G03C11/12
Filed: 1973-10-12

Patent FR-2262471-A1 (FR)
Title: Printed circuit board edge connector - has contacts of boards contacting fixed contacts when moved down and to side
IPC: H01R12/82
Filed: 1974-02-26
Abstract: Two U-shaped bars (11, 12) carry the resilient spring contacts, the spacing between the contacts of the two bars being equal to that of the rows of contacts on the circuit board. One row of contacts (10) abuts one longitudinal edge of the circuit board while the other row of contacts (9) is spaced from the opposite longitudinal edge. The spring contacts of one of the bars define a channel wider than the total thickness of the circuit board (1) and the first row of contacts (10) and deeper than the width of the contacts, so that the edge of the circuit board is accommodated in this channel when the board is inserted between the bars, and is then moved sidewards, so that the spring contacts engage the respective contact rows (9, 10).

Title: Hot air dryer for granular materials esp cereals - with dust sepn fan located outside drying circuit
IPC: F26B9/08
Filed: 1974-03-04
Abstract: Grain is cycled via a drying circuit comprising a screw elevator which raises grain to the top of an elevator column to be distributed into a surrounding air stream and to fall back eventually for re-elevation, the grain being cleaned during drying by sepg. off fines, dust, chaff etc. via a suction fan. Essentially, the suction fan intake comprises a hood fitted over the top of the elevator column and leading upwards into the casing of the suction fan which is driven by being connected to the rotating elevator screw shaft, transmission being pref. effected by a geared speed multiplier so that the fan shaft rotates much faster than the elevator shaft. Used partic. for drying cereals such as maize, prior to storage. The suction fan is positioned so that it does not impede flow of grain in the drying circuit; cleaning sepn. is improved and drying efficiency raised, resulting in a cleaner, cheaper prod.

Title: Selective filtration of fibres and large particles - in a granular bed at high flow rates
IPC: F28F19/00
Filed: 1974-06-25

The flow rate through the bed (2040-8160 litres/minute per square metre) is such that smaller particles are not retained. The flow conditions in the bed are given by the relationship: H/L = 3.4 (1-epsilon)V1.715 (Eta/e) 0.285-1.285 in which H is the pressure loss unit depth (L), epsilon = 0.32-0.42, V= 0.61-3.5 cm/sec., Eta = 0.2-20 Cp, = 640-2080 g/dm3 and D = 0.61-38.2 m.m. The filter is cleaned in a few seconds by reversing the direction of flow to fluidise the bed, washing out the trapped solids, and removing algae, slime, etc. by attrition. The filter is used esp. for cooling water in chemical plants.

Title: Improved method for digitisation of two-dimensional images - miminises storage requirement by selection of characteristic points
Inventor: ROCHE CLAUDE
IPC: G06V10/40
Filed: 1974-10-11
Abstract: When processing a two-dimensional image into digital form, storage capacity can be minimised by confining it to the variance, coordinates and angle of the characteristic points. These are defined as being on a contour, and at an angle to that contour. The process of determining the data for each characteristic point, from a matrix of all points, requires the storage and processing of the matrix. The contours of the matrix are determined at eight points and the difference determined for the absolute values of the circumferential and radial gradients.

Title: Ball bearing for light loads - has steel reinforcement shaft and housing for plastics races into which balls are inserted by elastic deformation
IPC: F16C43/08
Filed: 1976-01-27
Abstract: A ball bearing suitable for light loads has an outer race (1) and an inner race (2) made of plastics. The steel balls (3) are forced into position by elastically deforming the races (1, 2), and are retained by the flange (8) of the outer race (1). The rigidity of the bearing during service is ensured by fitting a steel shaft in the bore (9) and a steel housing around the outer race (1). The outer race can be reinforced against side loads by fitting a metal plate in the recess (6). This method of construction obviates the need for a cage to retain the balls (3) in the bearing.
