Abstract: ABSTRACT OF THE DISCLOSURE            A hydroturbine engine device having a plurality of notched discs mounted within a high pressure fluid chamber.  A high pressure oil input is provided along the edges of said discs at one portion of the unit and an outlet for the spent oil is pro-vided downstream thereof and adjacent thereto.  The discs are keyed to a center driven shaft for connection to a work output.          The turbine engine is connected to a high pressure oil pumping unit which supplies oil at high pressure to the input of said tur-bine engine.  The turbine engine is also connected to an electri-cal alternator which in turn is connected to a storage battery through a voltage regulator system.  The storage battery is used to at least partially drive the electric motor for the hydraulic oil pump.  Thus, a portion of the energy output of the turbine engine is utilized in a feedback system for the oil pump to par-tially supply the source of hydraulic oil pressure for the turbine engine.

Abstract: METHOD OF MAKING ETCHED-STRIPED      SUBSTRATE PLANAR LASER                ABSTRACT OF THE INVENTION         A method of making a diode laser in which a pump current confining channel is formed on the substrate side of a diode laser prior to growth of the active or recombination region of the diode laser.  The current confining channel is formed by providing, by diffusion, a rectifying junction on a substrate surface and then forming, by etching, a narrow channel completely through a central portion of the diffused layer and the rectifying junction.  The remaining layers of the diode laser are then successively grown.  The portions of the rectifying junction on both sides of the channel are reverse biased when the primary junction of the diode laser is forward biased whereby pump current flow is confined to a path through the channel.

Abstract: FRIED DOUGH PRODUCT AND METHOD     Abstract of the Disclosure A delamination resistant fried dough product such as a pizza shell having a unique structure is described.  It is composed of a flat at least partially fried body of soft porous dough and crispable outer crust with a plurality of blisters having generally hemispherical upwardly extending domed upper surfaces.  The blisters usually contain one or more cavities substantially larger in size than the pores of the dough.  The blisters are spaced apart from one another laterally and ligaments of dough are located between the blisters to connect the upper and lower surfaces of the crust for the purpose of unifying the crust and preventing the top portion of the crust from becoming delaminated from the lower portion during the frying process.  After the crust has cooled, a topping, such as a pizza topping, sugar or glaze, fruit, cheese, egg, custard, etc. is applied to the top surface of the crust which is then usually frozen.

Abstract: A B S T R A C T         Ultra-narrow-band system for communication between a transmitter device and a receiver device provided by locking both to a carrier signal from a radio broadcast station and synthesizing a precise local frequency at each device as a preset multiple of the frequency of the carrier.  Such a system is usable in a multi-station alarm and status communica-tion system including a multiplicity of independent radio alarm transmitters whose various carrier frequencies are different from but phased locked to a local radio broadcast station, and a central alarm receiving station which employs a corresponding multiplicity of synchronous detectors.  The detectors each have associated with them a synthesized local oscillator source which is also phase-locked to the same radio broadcast station used by the alarm transmitters.  Both the alarm transmitters and the central receiver are thereby accurately referenced to a readily available local frequency source (the broadcast station).  As a consequence, very narrow-band radio circuits may be employed and the receiver and transmitter bandwidth may be accurately matched to the information content of the alarm and status signal source to achieve high signal-to-noise ratio reliable transmissions.          The disclosed apparatus is relatively immune to intentional or unintentional interference and will burn-through most conventional transmissions which may be transmitting on the same radio channel at the same time, without unduly bothering these other unrelated transmissions.

Abstract: ABSTRACT   A foamed polymeric material is coated with a fire protective thermal barrier product.  The polymeric material, thus protected, is used for on-site application on walls, ceilings, docks and roofs of buildings.  The thermal barrier product (hereafter "thermal barrier" for brevity) is also used to protect foam plastics in fire-resistant factory-made building panels, the exteriors of tanks and other vessels, and the coverings over pipes.  The thermal barrier comprises a normally fluent thermosetting synthetic resinous material in which is dispersed an effective amount of hydrated magnesium sulfate and, optionally, inert inorganic fillers, pigments and the like.  The thermal barrier is flowed or sprayed onto the foamed polymeric material, optionally, with an adhesive interlayer or "tie-coat"therebetween, to form a fire resistant laminate which laminate meets the "15-minute finish rating" or "hourly rated" requirement of building codes as determined by a testing procedure currently designated ASTM E-119-76, and other fire resistance requirements as determined by other fire resistance test.  A process is disclosed for utilizing compositions belonging to a family of thermalbarrier products containing inorganic salts having water of crystallization which is driven off at a temperature from about 200°F but less than 600°F.

The electrons from this source are formed into a beam in which individual electrons are made to follow helical paths by a DC magnetic field. The angular velocity of the beam electrons is modulated as the beam passes through an oscillating electric field in a resonant cavity or waveguide so that a high power electromagnetic wave is established in the region as a result of an interaction between the beam and field.  A collector for the beam is positioned on the axis, while an output waveguide for the wave is positioned at right angles to the axis. Upstream of the collector, the wave is reflected to the output waveguide by a reflecting surface having an aperture for passing the electron beam to the collector.

Key stroke signals generated by the typewriter keyboard are stored in a memory prior to being applied to access corresponding type ball positioning signals within a table to print the characters using a conventional type ball on the fir t portion of the page. Thereafter, the conventional type ball is replaced by a special type ball and the key stroke signals stored in the memory are used to access corresponding ones of a different set of type ball positioning signals within a second memory to enable the special type ball to type optically readable binary coded representations of the characters on the second part of the page.
