Title: Demineralization of wheys - from cheese making by ion exchangers
IPC: C13B20/14
Filed: 1971-06-25
Abstract: Crude sweet or acid wheys, from cheese factories, are treated by passing first through at least one strongly-acid cation exchanger, and then through a wealkybasic anion exchanger, to remove first the Ca salts, proteins and colouring matter, and then the lactic acid. 1 to 10% of crude whey is added to the decationised whey before it is passed through the anion exchanger. The demineralised liquid may be treated to recover lactose. The ion exchangers are regenerated by passing first nitric acid and then ammonia through them, and the products removed and extracted. Various arrangements for semi-continuous working are given. Used for recovery of useful products from wheys from cheese making.

Title: Load guidance system for storage assemblies - uses beams of light to indicate height of handling device
IPC: B66F9/075
Filed: 1973-05-11
Abstract: Guidance system is for mechanical handling machining serving storage assemblies of the scaffolding frame type, in particular for fork lift trucks with a side-loading ability.

IPC: F16K31/04
Filed: 1974-02-05
Abstract: An electric actuator for varying the position of a valve stem comprises an output shaft adapted to be coupled to the valve stem. The output shaft is selectively rotated, between limit positions defined by a pair of electrical limit switches cooperating with cams carried by the output shaft, through the agency of a motor module comprising one or more electric motors and an associated gear box having an output pinion in drive engagement with an output gear coupled to the output shaft. The output gear includes two sets of concentric teeth disposed in spaced relation to one another, and adapted to be engaged individually by the motor module pinion, for driving the output shaft at different torques and speeds in dependence upon which set of output gear teeth is engaged by the pinion. The motor module can be mounted in either of two different positions to cause its pinion to engage one or the other of the output gear teeth sets. The output pinion is preferably located at an eccentric position relative to the motor module so that pinion engagement can be shifted from one to the other of the gear teeth sets by a 180 DEG  reversal in the motor module mounting position.

Title: IC engine ignition pulse generation - by charging generator capacitor under control of four time signals
Inventor: MOTTAIS JACQUES
IPC: F02P5/155
Filed: 1974-08-23
Abstract: Ignition voltage and automatic spark retard are produced by a system with a low number of components and competitive with traditional electro-mechanical techniques. The system is controlled from a sensor positioned such that it faces a specific sector of the crankshaft. This sector, as it passes the sensor, causes the sensor to start and finish an output pulse which after shaping, feeds a monostable oscillator. Four distinct pulses generated from this primary pulse control the start of the charge and discharge cycle of a capacitor associated with the e.h.t. pulse generator providing the spark energy.

Title: High pressure flexible tubing - allows greater flexibility and cheaper and quicker prodn. than current types
IPC: B60T17/04
Filed: 1974-09-23
Abstract: The flexible pipe, suitable e.g. for hydraulic brake systems requires only two operations in its production and may be bent at appreciable smaller radii than currently available types. It consists of an extruded polyamide inner tube on which are wound reinforcement webs of ethylene glycol terephthalate or similar plastic. Several such webs may be applied to form a square mesh which is finally covered by an outer protection sleeve by a coating process. The outer sleeve may be a polyurethane elastomer. Previously extruded inner tube passes from the drum through the rapid winding unit which applies the reinforcing webs. It then passes into the coating bath, which contains the elastomer in a mixt. of organic solvents, and through a die formed of multiple hooked wires which scrape off the excess elastomer. Finally it is dried in a vertical chimney and wound on to a receiving drum.

Title: Brazing metal parts - in an atmosphere of inert gas contg. thermally decomposable halides
Inventor: SEROLE BERNARD
IPC: B23K35/38
