Abstract: The present invention relates to slurries of synthetic alkali metal silicates with fine particles kaolin clay. The slurries consists of at least 50% solids which solids comprise an approximately 50:50 combination of the fine kaolin clay and the synthetic alkali metal silicate (SAMS). The integrated composition of the SAMS products is an entity having an overall composition ofxM.sub.2 O:Al.sub.2 O.sub.3 :ySiO.sub.2 Owhere x is the number of moles of alkali metal oxide and is an integer from 0.01 to 2.0, M is an alkali metal, y is the number of miles of SiO.sub.2 in the unique SAMS composition, and z is the number of moles of bound water and is an integer ranging from 1.0 to 5.0. The composition essentially comprises altered kaolin clay platelets with an integral rim or protuberance of essentially amorphous alkali metal silicate-kaolin reaction product. The slurry is useful in latex paint systems.

Abstract: A handheld screw driving gun (1) has a handle (17) extending essentially perpendicularly relative to the motor axis (3--3) and a screwing axis (6--6) which is off-set below the motor axis. The handle is connected approximately at the center of gravity of the screw gun (1). A screwing bit (5) is also off-set from the motor axis (3--3) and is rotatably supported in a guide head (7) between the motor axis (3--3) and the handle (17). In this arrangement, the index finger of an operator's hand on the handle approximately aligns with the axis of the screwing bit (5) so as to assure a screwing direction perpendicularly to a work surface without applying any tilting forces to a screw. The arrangement of the drive motor behind the handle and the screwing unit in front of the handle provides a balance that reduces fatigue while holding and operating the screw gun with one hand.

Abstract: A hand-operated cleaning system includes an ON/OFF control unit snap-on mountable onto a pressurized container having a valve stem for delivering cleaning liquid. This control unit includes an outer cap with resilient fingers adapted to snap-grip engage and mount the control unit onto a top rim of the container. An inner cap is mounted within the outer cap for ON/OFF helical turning movement so that turning the inner cap in the ON direction depresses the valve stem for releasing pressurized liquid from its container, and turning it in the OFF direction stops such release. A fluid passageway extends from the valve stem through the inner cap to a length of flexible tubing coupled to the inner cap and extending to a remotely-located, hand-held applicator wand. This applicator wand has a fluid passageway communicating with the flexible tubing for providing a path through the wand to its nozzle end. A valve is positioned in the wand for operation by a button actuator.

Abstract: A valve assembly includes a self-contained, packing removal means for removing the valve packing. The valve assembly includes a valve stem connected at one end to a valve, a bonnet for mounting the valve stem on a valve body having a valve seat engageable with said valve on said valve stem, and means for raising and lowering said valve stem to selectively open and close said valve. The bonnet includes a packing chamber through which an intermediate portion of the valve stem extends. The packing removal means comprises a radially displaceable lifting element disposed within the valve stem and movable to an extended position where it engages the packing assembly from underneath upon operation of the valve stem to lift the valve packing from the packing chamber.

Abstract: A fiber optic attenuator having a predetermined, fixed attenuation value and low back reflection properties across a broad wavelength spectrum is disclosed. Attenuation is achieved by providing an optical fiber pathway having an attenuation region which causes a predetermined signal loss. The medium defining the pathway is of a substantially constant index of refraction through the device to minimize or eliminate interference caused by Fresnel reflections.

Abstract: A method of communication in at least one cellular mobile radio system in an environment of additional mobile radio systems with mobile stations capable of communication with more than one of the systems on any of a predetermined group of radio channels, not all systems being capable and allowed to use all of the radio channels in the predetermined group, wherein all base stations transmit on at least one of the radio channels in the group information regarding system and base identity and the channels of the system, wherein a mobile station is prevented from transmitting on any of the radio channels until after receiving information on base and system identify and the channels of the system, and the allocation of a radio channel in the group for a call is determined by a mobile seizing an idle channel.

Abstract: A device for sewing together two fabric parts includes two pattern sensors and correcting means for determining and correcting misalignment of patterns on the fabric parts. Also, an additional image sensor (18) is provided, which scans the surface of the fabric (16) to be sewn at the site of an intermediate storage location (15) before this fabric is fed into the sewing machine. An image-processing device connected to this additional image sensor generates data on certain basic characteristics of the fabric pattern, such as color, contrast, lightness, register length, and angular orientation of the pattern components. From these characteristic data, a decision logic circuit determines setting data for the operating parameters of the devices used in the sewing machine for detecting and correcting a possible pattern misalignment during sewing.

Abstract: The invention relates to a method in mobile radio systems in which the responsibility for transmitting message information to a mobile station is handed over from a first base station transmitter to a second base station transmitter. In this method, the same radio channel is used, if possible, before and after the handover for transmitting message information to the mobile station. If the same radio channel can be utilized, the handover takes place without the mobile station being informed beforehand of the handover by a special signal or order or the like. In digital mobile ratio systems with digital transmission of message information by digital modulation of the radio signals, the transmission is preferably started from a second base station transmitter before the transmission is terminated from a first base station transmitter. During a certain transmission time substantially the same message information is transmitted to the mobile station from both the first and second base station transmitters.

Abstract: The dry end or dryer section of a paper making machine has a plurality of dryer groups. Each dryer group comprises a plurality of heatable dryer cylinders, reversing rolls between each pair of the dryer cylinders in the group and an endless web support belt which passes over a dryer cylinder and then a reversing roll and then the next dryer cylinder in turn in the group. Between the last two dryer cylinders with which the lower side of the web comes into contact, there is an auxiliary guide roll over which the support belt travels free of the web, while the web travels directly from the selected dryer cylinder to the next reversing roll. Alternately, the auxiliary guide roll is disposed between the reversing roll and the next dryer cylinder in the web path of travel. Between the dryer cylinder and the auxiliary guide roll can be provided a second auxiliary guide roll which presses the web against the belt before the web separates from the web to pass to the auxiliary guide roll.

Abstract: An improved dry ground calcium carbonate filler is provided which is less sensitive to variations in relative humidity and does not promote premature viscosity increase in polyester molding compound. This filler is dry ground from a Caribbean micritic limestone to produce Class I and Class II fillers which are acceptable for use in polyester molding compound applications. A polyester molding compound containing this dry ground filler produces a composite having superior izod impact resistance and surface quality. In some situations filler loading levels may be increased 10-15% in the SMC/BMC without detrimental effects on the final composite.
