A separating filter includes a band pass filter supplied with a composite color video signal, having a resonance frequency of a chrominance sub-carrier frequency, a first circuit supplied with the output of the band pass filter for generating first and second signals having the same phase but different time relationship, and a second circuit for comparing levels of the first and second signals with a level of a reference signal and for producing the signal that has a level nearer the reference l...

A device for separating a first liquid from a second liquid contaminated by the first liquid comprises a casing having an inlet and an outlet in the upper region of the casing, the separated first liquid collecting in the lower portion of the casing, a float which is arranged to float on the separated first liquid, the vanes for guiding the movement of the float and a seating in the upper part of the casing which forms a valve with the float, to prevent flow of liquid to the casing when the leve...

Molecular sieve pressure swing separating process is modified by stopping the feed before the end of the adsorption stage and passing a mixture richer in n-paraffins than the feed through the sieve bed. Suitable mixtures include purge effluent and desorpting effluent. This enhances the purity of the product.

This specification discloses improvements in a separating mechanism for forcibly separating transfer medium from an image bearing member after the visible image on the image bearing member has been transferred to the transfer medium. In the separating mechanism having a separation guide disposed between the image bearing member and a side edge of the transfer medium to direct the transfer medium away from the image bearing member, the separation guide has one end as a supported end and the other...

A separating device for separating by gravitational segregation a mixture of a carrier liquid and substances suspended therein comprises a separator arranged in a separator housing and having parallel, sloping plates, a stilling space arranged in front of said separator and having on the top side a first collecting space intended for light-weight substances, a feeding space near the inlet side of the separator, a second collecting space near the top wall and a third collecting space arranged beh...

A method for heating crude oil to be processed in a petrochemical installation, comprises successive heat exchangers disposed in series, each heat exchanger using pressurized steam as the heating fluid. Each exchanger has a lower exchange chamber, a liquid product supply line and a tube bundle, the steam transferring heat to liquid product flowing through the tube bundle. Each heat exchanger comprises an upper separation chamber disposed above the lower exchange chamber, the separation chamber h...

Apparatus for separating solid materials from mixtures having solid materials therein, including a wire mesh screen the two opposing edges of which are retained by elongated rigid retainer assemblies against which oppositely directed forces may be applied for placing the screen in tension. Each of the rigid retainer assemblies may comprise: a first rigid retainer member having an elongated flat base portion from one edge of which upwardly projects a curved rib portion providing an elongated arcu...

An apparatus for separating objects of a particular kind from other objects, e.g. stones etc. from potatoes during harvesting, wherein the objects fall in a stream past a detector for objects of said particular kind and, after detection of an object, a separating member positioned downstream of the detector is moved in a manner in dependence on a physical dimension of the detected object so that objects of said particular kind are directed in a first direction and other objects are directed in a...

Partitions or separating walls are disclosed. The partitions are particularly intended to be used in interlocking relationship with a number of such partitions, and include a pair of opposed surfaces separated by a transverse edge, tabs disposed along that edge, and having adjoining ends alternately projecting therefrom towards the first and second surfaces, respectively. In this manner, the wall or partition may stand in a vertical plane without weight resting on these tabs, as was the case in ...

A separating device for manually making separations in solid materials in which a separating blade has a row of teeth that performs oscillating movements with a component directed parallel and a component vertical to the row of teeth in which the amplitude is not greater than twice the distance of neighboring teeth.
