Abstract: Abstract of the Invention This invention relates generally to vacuum cleaner hose assemblies and more specifically to new and improved methods for providing improved vacuum hose molded on end fittings and assemblies employing injection molding. A two stage molding operation is employed by placing an electrical cord ter-minating in either a female or male plug into a two part mold.  Wire is pro-vided having its conductive wires opposite the plug or receptacle end located inside the injection mold.  The cord is sealed to the mold applying clamp pressure after which melted thermoplastic or thermoset material is injected into the insert mold cavity, thus providing the product of the first injection molding to be employed as an insert for the second molding process.  The in-sert thus provided is electrically connected by splicing and crimping to a current carrying hose.  A metal mold core is placed into the inside diameter of the hose, positioning and locating the hose insert on the mold core seat. The assembly thus provided is placed in the upper and lower mold cavities and clamped under pressure.  The thermoplastic or thermoset is then injected into the mold cavity which after cooling provides the molded end fitting perman-ently bonded to the hose having the plastic insert fused with the melted thermoplastic or thermoset of the end fitting.

Abstract: BONE GROWTH STIMULATOR                   Abstract of the Disclosure There is disclosed an improved implantable bone growth stimulator having a titanium, bullet-shaped case and pre-stretched helical electrode leads.  The leads are sheathed, and the circuitry in the case is potted in silicone elastomer.  The shape of the case lends itself to long-bone applications.  The potting material is ideal for presenting ionic contamination of -the circuit, while the metal case offers the requisite mechanical strength.  The shape of the case facilitates removal during an explant procedure, and the pre-stretching of the leads prevents tissue damage at this time.  The electri-cal circuit is a stacked assembly of components without a circuit board, which gives rise to the desired bullet shape of the case.

Abstract: 45,632-CAN/MAL             PHOTOTHERMOGRAPHIC STABILIZERS               Abstract of the Disclosure Photothermographic emulsions have traditionally had slower speeds and a tendency for increased background density with aging, which are undesirable characteristics.          The increasing optical density in the background areas is particularly undesirable.          The addition of certain classes of aromatic, nitrogen containing compounds to photothermographic emulsions stabilizes the background density of the imaged film and/or increases the speed of the emulsion.

Abstract: ABSTRACT OF THE DISCLOSURE           The object of the invention is a portable seat for mounting on an invalid walker to enable a walking invalid to sit and rest until strength is recovered sufficiently to continue walking thereby gaining greater freedom of independent mobility and exercise.  The seat comprises a rectangular, foldable sheet of material of sufficient strength to support a person.  The seat can be readily attached to the walker for seating to rest and readily detached for carrying on the person in pocket or purse for walking.  The seat is adjustable in one or more res-pects and can be mounted on the more complex of common walkers, such as some foldabl swinging walkers, walkers, without making holes in or structural changes to frame members.  Four hooks are detachably connected to respective frame members by means of ordinary hose clamps.  A metal ring is attached to the sheet at each corner thereof and the sheet is attached to the walker by placing each ring on a respective hook.  The seat can be manufactured from readily available common parts and installed using common skills and tools.

Abstract: ABSTRACT            A platinum-cadmium sulfide Schottky barrier photovoltaic detector which is capable of sensing near ultraviolet and short wavelength visible radiation with extremely small response to wavelengths longer than about 5200 angstroms.  The detector is fabricated with both the ohmic and barrier contacts located on the same side of the cadmium sulfide substrate to facilitate wire attach-ment by high-speed bonding techniques.  A titanium-gold-titanium infrared shield structure is deposited directly on the substrate and is utilized to provide a connection between the ohmic contact and the substrate.  An insula-ting layer of silicon dioxide covers the shield structure. A thin layer of platinum is deposited directly on the substrate in a small central optically active area sur-rounded by the insulated shield structure.  A metal boundary layer overlies the periphery of the platinum layer and prevents the barrier contact metalization from affecting the properties of the Schottky barrier.  Both the ohmic and barrier contacts may be formed of a titan-ium adhesion layer and a layer of gold.  The gold por-tions of these contacts touch the shield structure and the boundary layer through separate windows etched in the silicon dioxide insulating layer.

Abstract: ABSTRACT    The invention relates to an improved diffuser for fluid flow compressors which utilizes alternately swept diffuser vanes.  The invention utilizes a diffuser vane having a highly swept leading edge of approximately 70° sweep.  The vanes are made in two sets, one set having its leading edge extending from one diffuser wall toward the other, while the other set has its leading edge extend-ing from the opposite wall.  These oppositely swept stator vanes are then alternately spaced about the diffuser and, importantly, extend into the transonic  region of the diffuser space.  The angle or direction of the swept portion of the diffuser vanes which lie in the transonic region of the diffuser space is arranged to maintain a desired negative angle of incidence across the width of the flow path.

Abstract: Abstract In a plant for purifying contaminated air the contaminants are transferred from the air to a liquid flowing through a spray booth (1) through which the contaminated air (2) also flows under intimate contact with the liquid. The liquid is then collected in a container (5,13) from which it is recirculated to the spray booth. The closed liquid circulation circuit taking in the spray booth is connected to a biological cleaning step (12,13) in which the contaminants dissolved and/or suspended in the liquid are decomposed and then separated. The biological cleaning step comprises a bioreactor (12), known per se, in which the main portion of the bio-degradation occurs, and a separator(13) for separation of the biosludge coming from the reactor. At least part of the contaminated liquid passing through the spray booth (1) is continuously transferred to the biological cleaning step from which substantially the same quantity of the cleaned liquid is recirculated to the spray booth circulation circuit.

Abstract: ABSTRACT     A degreasing apparatus comprises a vessel (3) the lower portion of which is shut off by means of a bowl--shaped plate (5), to form a container (1) with a heating means (2) for boiling solvent. The bowl-shaped plate (5) has an opening (6) at its lowest point. A valve means (7) is  arranged at the opening (6). The valve means (7) comprises a body, preferably a ball, which can seal against a seat which surrounds the opening (6). The density and size of the body are related to the size of the opening (6) so that the body floats up from the seat in the pre-sence of solvent condensate, so that condensate can pass from the valve means to the container (1). Vapour pressur-ized in the container (1) by the heating means (2) lifts the body from the seat so that vapour can flow up into the treatment space of the vessel (3). When the apparatus is shut off, the body seals the opening (6) and thereby pre-vents evaporation of solvent from the container (1).     (Fig. 1)
