Abstract: ABSTRACT OF THE DISCLOSURE A bypass and unloader valve capable of operation as a full unloader valve or volume control for fluid pressure systems. The structure utilizes a valve body having an inlet, an outlet, and a bypass, with check valve means being provided to accommodate normal flow from the inlet to the outlet. When the pressure rises in the outlet, this pressure is applied against a reciprocatory plunger, and the force generated lifts the plunger, and a stem extension coupled to the plunger unseats a check valve, thereby opening a fluid path from the inlet to the bypass. Improved guide and sealing means are provided for the plunger and associated stem assembly, the plunger and stem being spring biased to accommodate normal flow.

Abstract: PREFABRICATED INSULATED PANEL AND WALL STRUCTURE PRODUCED THEREFROM     ABSTRACT         A prefabricated insulated panel includes a sheet-like face member and an insulating mat extending along one surface of the face member.  Complementary male and female formations extend along opposed edges of the face member and are adapted to matingly couple adjacent panels to form a contiguously extending insulated wall structure.  The face member has an upstanding flange which is offset from one of the edges of the face member and which cooperates with such edge to define a recess adapted to receive the insulating mat of the next adjacent panel therein.  The flange is adapted to facilitate attachment of the panel to a support and in a manner aiding in preventing heat flow through the panel.  Each panel has a side edge structure which is con-structed and arranged to minimize heat transmission through abutting side joints of adjacent panels while, at the same time, allowing for expansion and contraction of the panels.

Abstract: METHOD FOR DRY-ETCHING ALUMINUM AND ALUMINUM ALLOYS          Abstract of the Disclosure The specification discloses a method for dry-etching A? and A? alloys.  The etching method involves producing a plasma discharge in a mixed gas comprising boron trichloride and freon or other source of fluorine in the discharge and/or oxygen incorporated therein and patterning A? or an A? alloy by the produced discharge.          In this dry etching method, the etch rate of A? or an A? alloy can be remarkably improved over the etch rate attainable according to the conventional techniques, and the difference of the etch rate between A? or an A? alloy and other materials can be remarkably increased.  The patterned A? or A? alloys thereby produced can be used in the production of semiconductor devices.

Title: Infra-red detector elements and their  manufacture
Inventor: WITHERS RICHARD B
IPC: H01L31/18
Filed: 1979-07-26
Granted: 1983-07-26
Abstract: ABSTRACT:           An infra-red radiation detector element and its manufacture is disclosed.  The detector element has a mesa of infra-red sensitive material, e.g. cadmium mercury telluride, with separate metal electrodes formed on side-walls of the mesa from a metal layer.  This permits a significant proportion of the current flow occurring between the electrodes in operation of the element to pass across the bulk of the mesa between its side-walls and not adjacent its top surface where the carrier recombination velocity may be higher.  The mesa is formed by ion-etching using a masking layer e.g. of photoresist, and this permits reproducible etching over a uniform depth and the obtaining of a topographically rough surface to which the subsequently-deposited metal layer can have good adhesion.  The electrodes are formed from this layer by a lift-off technique using the same masking layer.  The ion-etch definition of the mesa can also be used to etch unmasked parts of a passivating layer on the element surface without any significant undercutting.
