Abstract: A new and distinct poinsettia cultivar originating as a sport of the Hegg variety disclosed in U.S. Plant Pat. No. 2,962 and distinguished by the bright red color of its relatively large bracts which have stronger stems and by its early blooming characteristic, especially when grown in the northern latitudes under the poor growing conditions of reduced light intensity and duration. This plant is medium to short in height, compared to currently produced varieties, is self-branching with many side shoots whether pinched or unpinched, and its rooting habit is uniform and fast. When grown for blooming at the same time as most other Hegg varieties, this plant may be grown at a lower temperature than usually required.

Abstract: A liquid injection expansion valve permits liquid refrigerant at high pressure, bled from the condenser, to be injected into the working chamber between the screws and intermediate of the suction and discharge sides of a helical rotary screw compressor for cooling the refrigerant working fluid and the captured oil. A solenoid valve limits bleeding of liquid refrigerant from the condenser at high compressor loads. A thermostat sensing the temperature of the screw compressor discharge, modulates the liquid injection expansion valve downstream of the liquid injection solenoid valve. A compressor unloader slide valve may port oil and the liquid refrigerant into the working chamber. The condenser may be positioned at a height considerably above that of the screw compressor to increase the head of the bled liquid refrigerant to a pressure higher than the screw compressor discharge pressure.

Abstract: A knee brace or orthosis for preventing hyperextension of the wearer's leg. In an additional embodiment the flexion of the wearer's leg is also regulated between positions permitting limited motion and a position wherein the knee is fixed and no motion is permitted. In its simplest form the orthosis includes upper and lower forward members and a rear member to which the upper and lower forward members are independently and pivotally attached. The forward rotational movement of the forward upper member is limited by abutting contact between opposed edges of the forward members, thus preventing rearward bending or hyperextension of the leg while permitting flexion. In the alternate embodiment, an upper rear member is provided and includes means for contacting upper portions of the rear member so as to limit flexion movement. In both cases the members are formed from relatively thin lightweight plastic material which has been at least partially shaped to custom conform to the dimensions of the wearer's leg.

Abstract: A system for continuous monitoring for open circuits in multiple lead EEG systems during patient testing. Means are provided for repetitively applying a low current signal, having a distinctive waveform and frequency, to each electrode of the system. In the event an electrode is detached from the patient's scalp or otherwise open, the distinctive signal is apparent in the recorded output. Otherwise the distinctive signal is of such low magnitude that it is below the signal-to-noise ratio of the EEG amplifier. In systems including multiple leads, the test signal is successively applied to each electrode in the system in a time-controlled sequence. In one preferred embodiment a distinctive signal is used comprising a four pulse burst of 25 Hz frequency.

Abstract: A mass of cubic boron nitride (CBN) crystals, aluminum or aluminum alloy and a silicon carbide ceramic substrate are disposed in a container which is placed within a pressure-transmitting powder medium. Pressure ranging from about 20,000 psi to about 200,000 psi is applied to the powder medium resulting in substantially isostatic pressure being applied to the container and its contents. To the resulting shaped substantially-isostatic system of powder-enveloped container, heat and pressure are applied simultaneously whereby the aluminum or aluminum alloy is liquefied and infiltrated through the interstices between the CBN crystals and diffused into the contacting face of the silicon carbide substrate sufficiently to produce, upon cooling, an adherently bonded integral composite.

Abstract: A photovoltaic cell having an electrically conductive substrate, which may be glass having a film of conductive tin oxide; a first layer containing a suitable semiconductor, which layer has a first component film with an amorphous structure and a second component film with a polycrystalline structure; a second layer forming a heterojunction with the first layer; and suitable electrodes where the heterojunction is formed from a solution containing copper, the amorphous film component is superposed above an electrically conductive substrate to resist permeation of the copper-containing material to shorting electrical contact with the substrate. The penetration resistant amorphous layer permits a variety of processes to be used in forming the heterojunction with even very thin layers (1-6.mu. thick) of underlying polycrystalline semi-conductor materials.

Abstract: A process step and material for use in the manufacture of semiconductor devices. To facilitate the etching of unmasked silicon dioxide, silicon nitride, silicon monoxide, bare silicon layers, or various refractory metals on preselected portions of a semiconductor slice, the material is exposed to a low pressure RF generated "cold" plasma (under 325.degree. C.) produced from a homogeneous gaseous binary mixture of oxygen and a halocarbon. The halocarbon is preferably a gas having one carbon atom per molecule and is preferably fully fluorine-substituted.

The tribasic acids should be used in conjunction with fuel oil, not only to reduce the reagent consumption, but also to increase the grade and recovery of phosphate concentrate.

Abstract: An improved process is provided for readily transforming a relatively low denier (i.e. 0.5 to 10 denier per filament) polybenzimidazole fibrous material to a carbonaceous fibrous material which contains at least 90 percent carbon by weight. The polybenzimidazole fibrous material initially is reacted with a solution of an acid (as described) to form a polybenzimidazonium salt, and the fibrous material subsequently is heated in a non-oxidizing atmosphere to form the carbonaceous fibrous material which retains the original fibrous configuration intact. A preferred acid solution for use in the present process is a dilute solution of sulfuric acid. The resulting carbon fibers are useful as fibrous reinforcement in the resinous or metallic matrix material.

Abstract: A pillow, which may take the form of an automobile headrest, has a fastener that controls communication to an interior compartment of the pillow. A removable shock absorber liner fits into the interior compartment and defines a pocket which is adapted to receive and store first aid (medical) supplies and emergency equipment. An elastic body fits into the pocket in the liner. The shock absorber liner and the elastic body are both easily removable from the interior of the pillow and are useful as first aid equipment. With the fastener open, a plastic, transparent organizer containing first aid equipment and emergency supplies is inserted into the pocket of the liner. This compresses the elastic body. The fastener is then closed. When the fastener is opened, the organizer is automatically at least partially ejected from the pillow.
