Abstract: A ground clamp for clamping to a cable shield to provide a round connection employs a U-shaped yoke. A keeper has a driver which threadably engages thread surfaces at the interior side of the yoke legs. The keeper has a clamp jaw which may be compressively engaged against a cable shield received in an aperture defined by the yoke. The yoke connects to a common ground point via a ground connector member. The ground connector member has a grounding portion which may comprise a flexible ground connector or a rigid conductive plate. A bracing portion of the ground connector member is connected to the grounding portion by a ramp portion which projects laterally towards the cable. The bracing portion includes two arms which project laterally from a center connector portion. The connector portion and arms define a horseshoe-shaped stress relief clamp which may be crimped into engagement with the cable to mechanically connect the ground clamp with the cable outer jacket.

Abstract: An extractive distillation process using a high boiling polyol such as glycerol is employed for separating high purity catechol, 3-methylcatechol and 4-methylcatechol from a high boiling, pitch-like dihydric phenol fraction. Fractional distillation first separates an impure overhead mixture of the catechol and 3-methylcatechol and an impure 4-methylcatechol bottoms. The impure overhead is extractively distilled to remove impurities and then extractively distilled again to separate the catechol and 3-methylcatechol. This produces a pure overhead of 3-methylcatechol and a bottoms of catechol and polyol which is distilled to recover the catechol and recycle the polyol. The impure 4-methylcatechol is distilled to remove residual material and then extractively distilled to remove impurities. The resulting mixture of 4-methylcatechol and polyol is distilled to recover the pure 4-methylcatechol and to recycle the polyol.

Abstract: The C.sub.2 to C.sub.5 and heavier acetylenes and dienes in a thermally cracked feed stream are hydrogenated without significantly hydrogenating the C.sub.2 and C.sub.3 olefins. Additionally, the C.sub.4 and heavier olefins may be hydrogenated. Specifically, the cracked gas feed in an olefin plant is hydrogenated in a distillation reaction column containing a hydrogenation catalyst without the necessity of separating the hydrogen out of the feed and without any significant hydrogenation of the ethylene and propylene. A combined reaction-fractionation step known as catalytic distillation hydrogenation is used to simultaneously carry out the reactions and separations while maintaining the hydrogenation conditions such that the ethylene and propylene remain substantially un-hydrogenated and essentially all of the other C.sub.2 and heavier unsaturated hydrocarbons are hydrogenated. Any unreacted hydrogen can be separated by a membrane and then reacted with separated C.sub.

Abstract: A super heat calculator for air conditioning systems comprising a microprocessor, a control panel, a temperature sensor, and a pressure sensor. Vapor pressure models for all expected air conditioning refrigerants are stored in a data storage unit of the microprocessor. Positioning a rotary switch on the control panel directs the microprocessor to utilize the vapor pressure model associated with the refrigerant assigned to the switch position. The temperature sensor and pressure sensor are installed between the evaporator and compressor of the air conditioning system. The temperature and pressure signals are sent to a dual slope analog to digital converter located in the control panel. The temperature of the refrigerant is automatically displayed when the calculator is turned on. Pressing the SUPER-HEAT button on the control panel initiates calculation of the degree of super heat. The microprocessor reads the refrigerant temperature and pressure values and stores them in the storage unit.

Abstract: The comminution apparatus comprises a drive shaft having a roller bearing which is disposed in a housing. A temperature detector mounted in the housing monitors the temperature of the roller bearing. Hydraulic fluid is supplied to a circumferential groove in the housing to apply hydraulic pressure to the outer raceway. The hydraulic fluid pressure is monitored by a pressure detector and gage and may be vented by a manually operated relief valve. The drive shaft is rotated at normal operating speed and normal load with the bearing clearance at maximum until the bearing reaches an equilibrium temperature. Raising the hydraulic pressure develops a force on the rear surface of the outer raceway, biasing the outer raceway towards the shaft and reducing the bearing clearance. Reducing the bearing clearance reduces waste heat generated by skidding between the rollers and the raceway.

Abstract: The double tapered die mount defines a channel to support the die shoulder. No contact occurs between the die and die housing. The die shoulder is machined to be in generally congruent relationship with the channel shape of the die mount of the invention. In the prior art, the die shoulder is perpendicular to both the inner radial surface and the outer radial surface of the die mount. In the preferred embodiment, the die shoulder is tapered from the inner radial surface toward the die edge to define an inner die taper. The die shoulder also tapers from the outer radial surface to the die edge to define an outer die taper. The side walls of the channel defined by the die mount of the invention taper inwardly to be congruent with tapered surfaces of the die shoulder. The inner channel wall, i.e., the channel wall closer to the axis of rotation of the die, contacts the inner die taper. The outer channel wall, i.e., the channel wall farther from the axis of rotation of the die, contacts the outer die taper.

Abstract: The rotor of a rotary regenerative air preheater is constructed for the loading of the heat exchange basket modules into the sectors of the rotor in a radial direction through the periphery of the rotor. The heat exchange basket modules are arranged in a plurality of axially spaced layers with the lower baskets supporting the baskets located above. To provide the support and to facilitate the loading of the baskets, each basket includes an integral grating structure at the top surface thereof which extends partially above the uppermost surface of the basket frame. This provides a clear sliding surface as well as a support for the baskets in the layer above. The invention eliminates the support gratings which are a part of the rotor structure, except at the bottom of the rotor.

Abstract: A rotary regenerative air preheater has heat exchange baskets which contain the mass of heat absorbent material commonly comprised of stacked plate-like elements. The heat exchange basket comprises a frame which is open on each end and which is closed on the sides by basket cover assemblies. Each basket cover assembly includes a light gauge membrane which is welded to the interior surface of the basket cover. Shrinkage of the membrane due to the weld imposes a pre-tension on the membrane which resists deformation of the cover assembly by the heat exchange elements.

Abstract: A single bed thermal oxidizer for oxidizing a contaminate in a gas (air) stream has a plenum above the bed containing burners for gaseous fuel and means for injecting excess air. The burners are activated to initially heat the adjacent top bed portion. The burners are then turned off and a mixture of gaseous fuel and air is passed down into and through the bed which oxidizes the gaseous fuel and transfers the hot portion of the bed downward to preheat the central region of the bed. At that point, the gaseous fuel is terminated and the contaminated gas stream is introduced into the preheated bed for oxidation of the contaminate.
