Granted: 1983-08-23
Abstract: PHN. 9540                        10 ABSTRACT:      A phase comparison circuit for producing at an output a signal which is a measure of the phase differ-ence between first (A) and second (B) pulse trains applied to first and second inputs respectively thereof and which is not responsive to the omission of a pulse from one of the trains nor to inequality between the lengths of the pulses in the two trains comprises a logic circuit, two activatable current sources, the out-puts of which are connected to a capacitor, an activat-able constant voltage source in the form of a control lable switch the output of which is connected to the capacitor, and a sampling circuit to the input of which the capacitor is connected.  The logic circuit generates the signals indicated at four outputs which are connected to activation signal inputs of the first current source, the second current source, the constant voltage source, and the sampling circuit respectively so that the charge on the capacitor is changed in a positive sense by the first current source during periods when a pulse of the first train is present while a pulse of the second train is absent, is changed in the other sense by the second current source during periods when a pulse of the second train is present while a pulse of the first train is absent, and is restored to a reference value (zero) by the constant voltage source in each period than pulses of both trains are absent simultaneously, the sampling circuit sampling the voltage across the capacitor in each period when pulses of both trains are present simultane-ously.

Abstract: ABSTRACT OF THE DISCLOSURE   To clean toner, particularly magnetic toner, from a photoreceptor, an improved cleaning subsystem includes a foam roll cleaner in contact with and mounted to rotate in a tangential direction opposite to that of the photo-receptor. The foam roll cleaner is mounted within a housing, and a baffle extends upwardly at an angle from the housing into the pre-nip zone between the photoreceptor and the cleaner in extremely close proximity to both the photoreceptor and to where the cleaner initially contacts the photoreceptor during rotation of the cleaner. This arrangement generates a positive pressure within the housing and to relieve this positive pressure without expelling any toner from the housing, filtered openings are provided in the housing. To discharge or release toner from the foam roll cleaner during operation of the cleaning subsystem, the cleaner is vibrated. Any magnetic toner accumulating on the interior surfaces of the housing are moved or conveyed downwardly into the bottom portion of the housing by magnetic conveyors located on the ex-terior of the housing.

Abstract: ABSTRACT OF THE INVENTION      A multiple part wheel cover adapted to simulate a wire spoke wheel when attached to a vehicle wheel comprises a retainer plate, separate inner and outer one-piece spoke as-semblies, and a hub cover.  The retainer plate has a peri-pheral rim around a central hub and is adapted to be-atta-ched to the vehicle wheel.  The rim also has two sets of spoke receiving recesses therein opening generally radially. Each spoke assembly comprises a one-piece injection molded plastic having an annular member of smaller diameter than the rim and integral with the radially inner ends of a plurality of spokes which extend from their inner ends to outer ends confined respectively within one of each of the two sets of recesses.  The annular member of the inner spoke assembly lies adjacent to and axially outwardly of the hub of the retainer plate.  The annular member of the outer spoke assembly lies adjacent to and axially outwardly of the annular member of the inner spoke assembly.  The hub cover lies adjacent to and axially outwardly of the outer annular member and is clamped toward the hub to secure all the parts together.      The wheel cover is fabricated by first forming the separate parts.  The retainer plate and inner and outer spoke assemblies are then supported coaxially in predeter-mined axial spacing.  Bending force is applied to the spokes to bend them resiliently within their elastic limits sufficiently to align their radially outer ends with their respective recesses in the rim.  Thereafter the bending force is progressively relaxed and the supported parts are simultaneously and progressively moved coaxially toward each other to cause the outer ends of the spokes to enter their recesses as the spokes straighten resiliently.  The parts are then secured together by clamping the hub cover toward the hub of the retainer plate, whereupon removal of the outer ends of the spokes from their recesses is pre-vented.

Abstract: ABSTRACT OF THE DISCLOSURE           A communication system connects a number of asynchronous remote data processing terminals, operating at different speeds, to a high speed switching and communication network.  One or two telephone pairs are used as a TDM link between the terminals.  The number of terminals that may be connected can be greater than the number of terminals that could be connected if all terminals were active simultaneously.  A signalling function or flag is used in the system to monitor the state of each terminal. This function, which distinguishes the resting or activity of the terminals, is based on a low speed search for the idle terminals, on a detection of their change of state, and on the time sharing allocation of the system's transmission resource between the active terminals.  The time sharing of the transmission resource is adaptive.

Abstract: "METHOD AND APPARATUS FOR SAMPLING A           CORE OF TAR SAND"                        ABSTRACT OF THE DISCLOSURE            The invention provides a method and apparatus for sampling a frozen core of tar sand.  The frozen core is first cut transversely along its length to form a pair of slabs of semi-circular cross-section. A longitudinal sample portion of substantially triangular cross-section is then cut from the central portion of the still frozen slab.  The triangular sample portion is ground in a cryogenic grinder to produce a finely divided, substantially homogeneous material from which small representative sub-samples may be obtained.  The triangular sample portion is cut from the slab by a pair of angularly disposed circular saws carried along the length of the slab.  The slab is supported and held by cradle means which fix the flat face of the slab in a pre-determined plane.  The longitudinal sample portion thus formed has a triangular cross-section of substantially constant cross-sectional area.

During operation the compressed fluid flows into the groove to urge the seal element against the end plate of the opposite scroll member so that the axial sealing between the spiral element and the end plate is assured without leakage of fluid along the groove. Also, the closed portion is located along the spiral element at the location where the line contact point where the outer fluid pockets and the central pocket merge to prevent back pressure changes from causing excessive wear of the seal element.

Abstract: Abstract of the Disclosure Acetal-coupled non-ionic surfactants are-easily degraded into relatively environmentally inoccuous fragments having little or no surface activity.  The fragments are sufficiently low in molecular weight to be oxidized when exposed to water and atmospheric oxygen.  The surface activity can also be destroyed by lowering the alkalinity of the medium in which the non-ionic surfactant is utilized to below pH 7.  The non-ionic surfactants of the invention unexpectedly have very low viscosities as compared to surfactants containing a comparable molecular weight and oxyalkylene residue content.
