Patent CA-1114011-A (CA)
Inventor: FRANKE WALTER
IPC: G03G15/20
Filed: 1978-10-20
Granted: 1981-12-08
Abstract: ABSTRACT OF THE DISCLOSURE              A positively heated fusing roller and a not positively heated counterpressure roller define a roller nip through which copy paper bearing toner images to be fused is transported, with the toner images in contact with the peripheral surface of the heated fusing roller.  The two rollers are driven by a drive mechanism during copying operations but not driven by that drive mechanism during the intermediate ready intervals during which the copying ma-chine is awaiting a copying command from the operator.  Because the fusing roller radiates heat to the counterpressure roller during the ready intervals, there is a tendency for the peripheral surface of the counterpressure roller to become non-uniformly heated, which can result in non-uniform fusing of toner along the length of the transported copy paper.  In accordance with the present invention, at least the not positively heated counterpressure roller is auto-matically rotated during the ready intervals, preferably at a speed lower than the speed at which the rollers rotate during copying and fusing.

Abstract: ABSTRACT OF THE DISCLOSURE                A "wood type" golf club comprising a plura-lity of separately constructed and finished components is disclosed.  In its preferred form, the golf club comprises a face plate, a club head block and a reinforcing collar.  The face plate, the club head block and the collar are separately constructed and finished and subsequently as-sembled into a finished golf club.  According to the invention, the construction and finishing of the individual components and subsequent assembly thereof is such that at selected interfaces be-tween the components of different material, rela-tive movement of the components due to thermal expansion, moisture, etc. does not produce visible component interface separation lines.  This may be accomplished by providing unequal peripheral dimen-sions of the components of different materials at the selected interfaces.

Abstract: ABSTRACT OF THE DISCLOSURE          A device for measuring gases and vapors which tend to form aerosols in humid air, comprises, a duct or test tube for the passage of a test gas there-through which includes a forelayer in the duct through which the test gas is passed, and which has a sub-stance which will react with the test gas to form a new gas substance.  The gas-permeable forelayer advant-ageously acts as a filter for the aerosol and comprises a substrate, such as a silica gel or a glass fiber, which is impregnated with a material, such as zinc dust and arsenic trioxide which is saturated with water.  The aerosol which contains a sulfuric acid in the gas will react after deposit in the forelayer with the zinc forming a nascent hydrogen which reduces the arsenic trioxide immediately to arsenic hydride The test tube also contains an indicating layer with a material which is known for producing an indication of the newly formed gaseous substance.

Abstract: ABSTRACT OF THE DISCLOSURE      The invention provides for flameproof, weatherproof enclosures for electrical equipment for use in hazardous areas where flammable gases or other substances are or may be present in quantities sufficient to produce explosive or ignitable mixtures during normal operation of the electrical equipment. The enclosure which is of sufficient thickness and mechanical strength to withstand the internal ignition of explosive gases is sealed for weathertightness and is provided with a metallic flametrap having a replaceable filter element therein of metallic foil or mesh structure to provide for cooling and deionizing products of combustion as they pass from within the enclosure to atmosphere through the flametrap.  The outer end of the flametrap is sealed by a bursting disc of predetermined burating strength which seals the flametrap against the weather.      A translucent portion may be formed in the enclosure.      The filter element may be in the form of alternate planar strips of metallic foil and crimped strips of metallic foil in face-to  ace relation and either folded, stacked or coiled and held together by an annular clamping member.

Abstract: IMPROVED METHOD FOR             SEPARATING SOLIDS FROM COAL LIQUIDS                  Abstract of the Disclosure The rate of separation of suspended mineral particles from a coal liquid is increased by adding a mixture of a hydro-carbonaceous oil and a calcium salt, such as calcium carbonate, to the coal liquid.  The increase in the separation rate as achieved even though the coal mineral particles naturally contain a calcium salt.  The premixing of the calcium salt with hydro-carbonaceous oil considerably enhances the separation rate as compared to the addition of the calcium salt alone even when the hydrocarbonaceous oil is a distillate fraction which is derived from the coal liquid itself.

Abstract: ABSTRACT OF THE DISCLOSURE         A unitized combination motor starter is provided with a single insulated housing wherein a plurality of pole units are disposed side-by-side.  Each pole unit includes a circuit breaker contact section and a contactor contact section.  A spring powered mechanism for circuit breaker operation is disposed on one side of the pole units and an electromagnet for contactor operation is disposed on the other side of the pole units.  The current elements of each pole unit are arranged to provide a current loop having re-latively close opposing arms so that large mechanical forces accom-pany high magnitude current flow.  These forces are directed so as to produce a blow-off effect at the circuit breaker contacts, re-sulting in current limiting action to protect the contactor contacts.          A removable and replaceable overload sensing electromagnet is pro-vided for each of the pole units, and the coils thereof are of re-latively high impedance to act as a current limiter during short circuit conditions to thereby protect heaters of overload relays connected in series with the unitized combination.

Abstract: RCA 73,017 Abstract A noise cancellation circuit is provided for cancelling impulse noise in a composite video signal. A composite video signal which may be contaminated with impulse noise is coupled to a noise inverter and an active filter.  The noise inverter generates an inverted noise pulse for each noise pulse in the composite video signal which exceeds a predetermined threshold level. The active filter delays the composite video signal and combines the delayed video signal with the inverted noise pulses, resulting in cancellation of the impulse noise. The noise-free video signal is amplified by the active filter for subsequent signal processing.  The threshold level of the noise inverter varies in response to the signal level at the output of the active filter.  The active filter utilizes a feedback capacitor to delay the video signal and to improve the transition time of the leading edges of synchronizing signal components of the video signal.  The feedback capacitor may be constructed from N+P+ semiconductor material, which is especially advantageous in integrated circuit manufacture.
