Title: Solvent extraction of aromatics - giving higher yield or purity
IPC: B01D11/04
Filed: 1972-03-08
Abstract: Solvent extn. of the desired liq. substance, partic. aromatics, from feed containing at least two solvents of different b.pt. above that of the reffinate, introduces each solvent separately at different extn. column positions, to obtain either purer raffinate with reduced solvent loss, or higher extract yield, less solvent free, than before. For almost solvent free raffinate, the enriched solvent component (A), characterised by max. insolubility and high selectivity w.r.t. the substance to be extracted is introduced into the extn. column, where raffinate is taken off, while enriched solvent component (B), characterised by high solubility therein of the substance to be extracted is introduced between the inlets for the feed stock and solvent (A), or vice versa for high yield. The usual reflux column is on stream between extn. and solvent recovery columns. In the latter, raffinate is distilled off, and the lower boiling solvent between inlet and base and/or from the overheads receiver, while the higher boiling solvent is taken from the base. Both components are distilled off in the reflux and solvent recovery columns, but the lower boiling solvent may be distilled off by itself, or in addn. to the overheads.

Title: Load compensator for super charged compression ignition engine - has speed change sensor to adjust air and fuel feed
IPC: F02D41/00
Filed: 1974-03-26
Abstract: The engine turns a generator which is provided with a revolution counter sensor whose contacts close when the generator speed falls below the required value. The signal influences the air feed by means of a magnetically operated throttle flap, the air pressure intake unloader valve and the fuel volume delivery rack. When a sudden load occurs, the regulator responds to the speed sensor to close a circuit which activates the solenoids to feed additional air and fuel to the engine. The additional air comes from either a super charger or a compressed air storage tank.

Patent FR-2272354-A1 (FR)
Title: Dryer for granular prods. e.g. cereals - of module construction with separate fans, delivering hot and cold air
IPC: F26B17/12
Filed: 1974-05-21
Abstract: Dryer for granular prods., e.g. cereals, comprises a superstructure comprising >=1 group of two columns with perforated walls for the descent of the grains. The columns are built up from a number of modules each with its own delivery chamber, connected to a fan, adjacent to one of the perforated walls. The suction inlet to the fan is connected to a feed chamber with an adjustable orifice for the admission of cold air; a lateral orifice is connected to a hot air column formed between the frontal wall of the column of modules and the rear portion of a central, vertical box, extending over the whole height of the structure. Hot gases are produced by a burner at the top of the vertical box. The opening of each orifice can be regulated by a sliding damper which can shut off the air supply to the corresponding module. The air drawn in by each fan flows through the perforated walls, either directly to the outside atmos., carrying the moisture with it, or into the central chamber. Inter-connecting pipework is reduced to a min. so that thermal losses and the power consumed by the fans are low. Each module is independent so that the failure of a fan does not prevent the operation of the remainder of the dryer.

Title: Three position steam valve with integral condensate trap - has by-pass with adjustable throttle valve
IPC: F16T1/38
Filed: 1975-04-01
Abstract: A three position rotary valve links a condensate trap with a steam pipe line. The trap is an integral part of the valve body with two connection lines to the valve cylinder. When the valve is in the working position, the steam flows from the inlet line through the trap into the condensate line. The second valve position connects the steam line directly with the condensate line, thus bypassing the trap. The third valve position also bypasses the trap, instead, the steam flows through a throttle valve. Hence a controllable steam - condensate flow is obtained in this valve position.

Title: Data transfer between peripherals in micro-processor system - programmed ROM carries all transfer instructions between teleprinter and card readers
IPC: G06F13/12
Filed: 1975-04-09
Abstract: The control of data transmission between automatic type writers and card readers in a micro-processor system is determined by a programme stored in an R.O.M. A microprocessor, e.g. Intel 8008 (R.T.M) has a memory coupled selectively to either a teleprinter or card reader over decoding circuits and a control unit. Information to or from the typewriter is controlled through the control unit, as in the input to the card reader mechanism. A memory matrix consists of a random access store for data, a random access memory for the main program and a react only-memory containing a fixed programme. The ROM controls directly the transfer of information to and from the micro processor and the teletypewriter and card reader units. Several typewriters and card readers may be linked to the processor in this way.

Title: Pneumatic control for guillotine - uses simultaneous pressure on two buttons and has distributors in feed to clutch lever and brake pedal jacks
IPC: B26D7/04
Filed: 1975-04-11
Abstract: The pneumatic control system has a compressed air feed (1) and individual jacks (11, 12) which operate the clutch-lever and brake-pedal. Primary (8), secondary (6) and tertiary (13) distributors are included in the compressed air control circuit. When piloted, the primary distributor feeds the clutch jack. The secondary distributor is recoil sprung, and when not piloted, furnishes piloting pressure to the primary distributor. When piloted this secondary distributor activates both jacks, and can only be piloted by simultaneous continuous pressure on two interspaced control (5) buttons. The tertiary distributor is piloted when the tool attains the upper 'dead' point and annuls the piloting of the primary distributor.
