Abstract: ABSTRACT OF THE DISCLOSURE         An electro-sensitive recording member includes a substrate on which there is disposed an electrically conductive, light colored intermediate layer comprising a pigment and a binder.  The color of the intermediate layer is convertible to a darker color in response to the application of an electrical current or discharge thereto. Disposed directly on the intermediate layer is a white surface layer that is no greater than approximately 10 microns thick and which is capable of being destroyed by application of an electrical current or discharge thereto to expose the intermediate layer.  Electric current is selectively applied to the recording member by a stylus, and the electric current or discharge destroys the white surface layer to selectively expose the intermediate layer in accordance with an image to be recorded, the image resulting from the color contrast between the exposed and non-exposed portions of the intermediate layer.

Abstract: Abstract of the Disclosure A stored program digital signal processor (e.g., Digital Equipment Corporation PDP 11/40 is used to collect billing data (e.g., Initial Entry data for Automatic Message Accounting) from a common control circuit (e.g., marker) of a  common control automatic telephone switching system (e.g., the Bell System No. 5 Crossbar system).  Ten marker control status indicating leads are scanned by the signal processor fast enough to detect any change in the signals on the ten status leads which, in signal content as a group, represent the control status of the marker at any given time.  When two successive prescribed control status changes occur, a large number of marker data leads are scanned by the signal processor so as to allow collection of that data and the storage thereof in a marker core buffer area of the signal processor.  The stored data, previously registered in the marker incident to the assumption by the marker of certain control statuses, includes such Initial Entry data as calling circuit identity, called circuit identity, type of call, trunk circuit used, et cetera.  The collected data is involved in subsequent processing (not disclosed) of the entire billing data for a call responsive to answer and disconnect timing entries.                             - i -

Abstract: PATENT APPLICATION                   For PERMANENT MAGNET STRUCTURE FOR CROSSED-FIELD TUBES                   By Alfred W. Cook and Thomas H. Schultz ABSTRACT             A permanent magnet structure particularly beneficial for generating the interaction field in coaxial, crossed field electron tubes is designed such that the normal iron flux return path is not required.  Substantial reduction in weight results.  A further benefit is that a magnetion interaction structure including the magnets may be built as a unit replaceable in the field in a stabilizing cavity structure.  Since the cavity structure contains no iron the magnets are not demagnetized in the replacement process and there are no mechanical mounting problems caused by magnetic forces.

Abstract: ABSTRACT OF THE DISCLOSURE          An improved, economical method of converting scrap metal, particularly machine turnings, to a powder having useful characteristics for warm or hot powder forming techniques, is disclosed.  Cryogenic processing is employed in which machine turnings are cooled to below their ductile-brittle transition temperature by the use of liquid N2; copper ball milling elements are employed as multiple function elements:  fragmentizers, cold-working elements and coating elements.  The resulting mass of liquid N2 and metal pieces are circulated so that in one zone a true slurry exists with a liquid N2 in intimate contact with the metal piece, and in another zone the metal pieces are withdrawn from the slurry to momentarily increase in temperature.  Fragmenting occurs substantially in said one zone and cold-working substantially in said another zone, while progressive copper coating of the comminuted particles occurs in both zones.

Abstract: NEH:pb APPARATUS FOR CONTROLLABLY ADMINISTERING A PARENTERAL FLUID          Abstract of the Disclosure An apparatus for administering parenteral liquids from a parenteral fluid container which provides a sufficient quantity of parenteral liquid to be administered at a slower than normal rate so as to afford a keep-vein-open (KVO) means.          The apparatus utilizes a first orifice to afford a faster flow rate than a second orifice spaced away from the first orifice.          The preferred means for regulating different flow rates of fluid through the two orifices are the dimensions of the ori-fices and filters having different mesh sizes.  When the par-enteral liquid is maintained in the reservoir in contact with the first orifice with the faster flow rate, liquid will pass through both orifices at a predetermined regular rate.  When liquid no longer contacts the first orifice, as when the fluid container is depleted of liquid, the second orifice then comes into effect to afford a slower rate of liquid until a new con-tainer can be supplied.

Abstract: ABSTRACT OF THE DISCLOSURE           A machine for automatically inserting parallel lead type electronic components into holes in a P.C.B.  The machine handles the electronic components in strip form, i.e. attached to a continuous web.          The machine includes two pairs of gripping members, the member of each pair being relatively movable to grip a respective lead wire of the leading electronic component of the strip.  When the leading component is thus gripped above a pair of holes in the P.C.B., a ram is operated to engage the component, while the gripping members are being released, and force the leads into the holes.  The gripping members are designed so that they do not project rearwardly of the leading component so that they cannot inter-fere with the next component on the strip.  Thus, the components can be very closely spaced and their size is not as severely limited as with prior machines.

Abstract: Abstract of the Disclosure At a channel bank, such as a D-type channel bank used in the Bell Systems, a steady visual alarm is exhibited if the source of a detected failure is at a location either within the channel bank or in the digital hierarchy of a digital transmission network. Unfortunately, a craftsperson is unable to distinguish between the two failure locations. To distinguish between the locations, apparatus for indicating the failure location to be in the hierarchy is situated be-tween the hierarchy and the channel bank and, responsive to an alarm failure signal from the hierarchy, extends a predeter-mined cyclic code signal to the channel bank. Without modification of the channel bank and responsive to the code signal, a cyclic visual alarm in lieu of the prior art steady alarm is provided thereat.
