Abstract: ABSTRACT OF THE DISCLOSURE          A machine for opening bags comprises a pair of spiked rollers mounted adjacent bur spaced from each other for rotation in opposite directions.  The axes of rotation are parallel and on the same level and a reciprocating knife is disposed in a cutting gap between the two rollers.  A conveyor brings a bag to be opened to the rollers which then carry it onto the knife so that the bag is cut in half allowing the contents to fall out under gravity.          The two bag halves may be detached from the rollers by a comb or by making the spikes cyclically retractable below the roller surface and the mechanism can be enclosed in a pressurised enclosure to restrict the production of dust.

Abstract: ABSTRACT OF THE DISCLOSURE      The objective of the invention is to modify the reflection of a radar wave ?? ? metal target object, by modifying the radar scattering cross-section of the object.  In some cases, such as an enemy aircraft, it will be desired to make the target appear smaller, while in other cases, such as navigation beacons, it will be desired to make the target appear larger.  The target is provided with a screen or layer of dielectric material conforming with the general shape of the body, and mounting that screen or layer on the outer side of the body in spaced relationship thereto.  As a result, an incident pulse will pass through the screen or layer before impinging on the body and the consequent reflected or reradiated radar pulse will emerge from said layer in a diffuse or scattered manner.

Abstract: ABSTRACT OF THE DISCLOSURE     A system and method for detecting the presence of useful speech information in telephone voice channels capable of containing noise as well as such useful speech information for optimizing the telephone transmission of such speech information.  Two segments of the envelope of a given voice channel are compared against each other over two different time domains in order to determine if a predetermined magnitude of difference exists between these envelopes.  The presence of such magnitude of difference is indicative of the presence of such useful speech information in the voice channel thereby enabling transmission thereof by the system, whereas the absence of such magnitude of difference is indicative of the presence of solely noise thereby preventing the transmission thereof by the system.

Abstract: FILTER HOUSING                  Abstract of the Disclosure A filter housing is disclosed.  It is preferably used to house membrane filters supported on plates.  The base, top and a two-way cap cooperate to form a pressure-tight vessel.

The structure of the housing is such that all surfaces exposed to liquid are free of screw threads or other surface con-figurations which are not readily sanitizable or steriliz-able, particularly by autoclaving.  Also, since the tightening mechanism is outside the filter enclosure, the filters can be sterilized by autoclaving and subsequently tightened into position.
