Abstract: ABSTRACT      A gang conveyor drive mount for a frame base comprising in com-bination a pair of rails secureable to the frame base, and a motor gear box assembly attached to the rails.  A drive shaft enages the gear box which is mechanically connected to the motor.  At least one conveyor is slidably mounted along the drive shaft and rails and ex-tends over the frame base such that the results of work fall on the conveyor in order to be carried away to a storage or use area.  At least one bracket is slidably mounted along the pair of rails, and at least one bearing is fixed to the bracket and slidably mounted along the drive shaft.  The conveyor and the combined bracket-bearing are adapted in operation of the invention to be slidably adjusted along the drive shaft and the rails in order that the gang conveyor drive mount can be mounted on any given frame base.  A method for transporting the results of work comprises engaging the drive shaft to a motor gear box assembly, and securing the motor gear box assembly to the rails.  The method also includes sliding along the drive shaft and the rails at least one conveyor until the same extends over a predetermined area of a given size frame base such that the results of work fall on the conveyor.

Abstract: ABSTRACT            The transportation of solids and particulates in an air-filled pipeline is usually over short distances and is normally uncontrolled due to the fluctuations of the pipe-line air  pressure, volume and velocity and the cargo speed itself.  The application of this mode of transportation has had limited commercial use because of the self-destruction of the cargo itself unless it is considered to be of hard material like sand, gravel, etc. In this invention the air/solid encasement system provides full control over all aspects of the process itself.  The cargo particulates are moved swiftly in a large diameter main transport cargo pipeline where it receives its air masses from a parallel pipeline which is intermittently connected to the transport cargo line to produce energized air.  The high pressure, high velocity air is introduced in such a manner so as to form an encasement of air around the cargo, thus confining the cargo distribution to the core or centre portion of the transport line.  The energized air is com-pletely controlled at will and its operating characteristics may be widely varied to provide an air cushion  or encase-ment of delicate particulate which can be transported over long distances without damage to itself.  Such a system will have a wide application for cargo transportation like grain, coal and other similar particulates.  The system providing flexibility for the changing of cargo, loading and unloading at terminals is accomplished with ease.

Abstract: ABSTRACT OF THE DISCLOSURE            A polyolefin blend comprising, in physical admixture, a major portion of particles of a polyethylene and a minor portion of particles of a composition of a thermoplastic second polymer, is disclosed.  The polyethylene is selected from the group consisting of homopolymers of ethylene and copolymers of ethylene and at least one C4 - C10 higher alpha-olefin, and the second polymer is a normally solid thermoplastic polymer having a melting point of less than 185°C and a shear viscosity that is not more than that of the polyethylene when measured at 200°C and a shear rate of 400 sec-1 with the proviso that the second polymer is not a homopolymer or copolymer derived solely from hydrocarbon alpha-olefins having 2-10 carbon atoms.  Examples of second polymers are (a) homopolymers and copolymers of unsaturated hydrocarbons in which at least one monomer is other than a C2 - C10 alpha-olefin, e.g. ethylene/propylene elastomers, polystyrene and styrene/-butadiene/styrene copolymers, (b) copolymers of ethylene with ethylenically unsaturated carboxylic acids and anhydrides, and esters thereof, and (c) modified polymers e.g. chlorinated polyethylene, grafted and ionomeric polymers.  The composition of the second polymer contains a reactive agent that is capable of reacting with polyolefins that are in a molten state, such agents being cross-linking agents and/or modifying agents.  In an alternative embodiment, the polyethylene may be more broadly defined as being a homopolymer or copolymer of hydrocarbon alpha-olefins having 2-10 carbon atoms.  The blends may be used in a wide variety of processes, including blow-moulding processes, film and pipe extrusion processes, sheet thermo-forming processes  and rotational moulding processes.

Abstract: ABSTRACT     Integrations of the historical numbers of times that a light beam scanned in an oscillatory course by a self-reonant galvanometer scanner does traverse so far in a first direction co as to impinge upon a Beginning-of-Trace (BOT) sensor, and does traverse so far in the opposite direction so as to impinge upon an End-of-Trace (EOT) sensor, are each used to seperately control the voltage level developed in a first, BOT, electrical tank circuit and in a second, EOT, electrical tank circuit.  Voltage from each tank circuit is amplified and applied to drive the self-resonant scanner, at a polarity to induce continued oscillation, during one-half of each oscillatory cycle.  Amplitude and centering contol thereby obtained of the sinusoidal oscillation of the self resonant scanner is repeatable to better than one part in ten thousand between cycles.

Abstract: SUPPRESSED DOUBLE-SIDEBAND COMMUNICATION SYSTEM          Abstract A bandwidth reduction technique is disclosed for use in digital systems wherein a pair of data signal elements modulate quadrature-related carriers.  This modulation, referred to as quadrature amplitude modulation (QAM), phase shift keying (PSK) or amplitude and phase shift keying (APSK), generates a double-sideband signal which is transmitted in a variety of communications systems.  In accordance with the present invention, the above-described double-sideband signal is filtered to form either a single sideband or vestigial sideband signal prior to transmission.  While this use of a vestigial or single-sideband signal, in lieu of a double-sideband signal, permits the transmission of more information in a given frequency interval, the filtering process contaminates the data signal elements.  To recover the data signal elements at the receiver, a pair of received signal elements is formed by extracting the carrier signals.  One of these received signal elements is then altered at selected times to recover an associated one of the data signal elements at each selected time.  Finally, this associated data signal element at certain ones of the selected times is combined with the other one of the received signal elements at an associated time to form the remaining data signal element.
