Abstract: A thermally insulating glass panel comprising two spaced-apart sheets of glass enclosing a low pressure space, and interconnected by a peripheral joint of fused solder glass and an array of pillars transversely between the glass sheets. The pillars may be made entirely of metal. Alternatively, the array may be made of a combination of solder glass-containing pillars and non-solder glass-containing pillars. Additional support pieces may be arranged between the glass sheets before the peripheral joint of solder glass is fused.

Abstract: A thermally insulating glass panel comprises two spaced apart sheets of glass enclosing a low pressure space and interconnected by a peripheral joint of fused solder glass and an array of support pillars, and a pump-out tube used to provide communication between the low pressure space and the exterior of the panel during the creation of the low pressure space. The support pillars each comprise a preformed core of a selected geometry and a selected material and a coating of solder glass at least in the areas between the preformed core and the sheet glass. Preferably the preformed core is spherically shaped and completely coated by solder glass. The preformed core serves to separate the glass sheets during the heating process of the panel's fabrication when the solder glass is in its molten state, and the solder glass serves as a mechanical joint to support the glass sheets after solidification.

Abstract: A conveyor system for transferring yarn packages or other yarn packages from one conveyor belt to another downstream located conveyor belt traveling in the same conveying direction and at the same speed. The conveyor belts are guided on support structures which are embodied as lateral guide elements which are height-adjustable in a selected area. The lateral guide elements are connected by a linkage such that, when the inward guide elements are lowered, the outward guide elements are simultaneously raised, thereby to cause yarn packages to gravitationally roll from the first belt to the other belt.

Abstract: A yarn splicing device for textile winding machines comprises a splicer mechanism for pneumatically joining yarn ends, upper and lower clamping and cutting devices, and suction-actuated yarn placement devices for placing the yarn ends to be spliced. According to the invention, one yarn placement device is a gripper tube normally parked in a zero position upstream of the yarn travel. The gripper tube has a spring-biased, pivotable gripping flap and a yarn placement hook for simultaneously placing both the lower yarn and the upper yarn to be spliced. For that purpose, one of the gripper tube and gripper tube flap carries the yarn placement hook forwardly for manipulating the upper yarn and a yarn guide disposed between the yarn placement hook and the pivot axis of the flap for placing the lower yarn.

Abstract: A device for determining the velocity of a longitudinally traveling textile material, especially a yarn, using the closed-loop correlation of a transit time correlator in such a way that its reliability is improved. At least one sensor g.sub.1 consists of two signal receivers disposed one behind the other in the running direction of the yarn, having a sensor output characteristic curve with the intersection of the abscissa in the effective sensor center axis, and wherein the output characteristic curve shows a point-symmetrical behavior at least in the vicinity of the intersection with the abscissa. A second sensor g.sub.2 has a steady state output characteristic curve in the area of its effective sensor center axis. The control loop circuit of the transit time correlator is designed such that the undifferentiated cross-correlation function is used as the controller input signal for determining and readjusting the adjustment point for the model delay time .tau..

Abstract: A pneumatic debris aspirating device adapted to be retrofitted on open-end spinning frames originally designed for a mechanical debris disposal installation utilizes an asymmetrical debris pickup funnel which can be connected via a connector conduit to a source of suction which is part of the spinning mill. The debris aspirating device is embodied and disposed such that opening of a cover to each rotor spinning unit is not hampered.

Abstract: A method and apparatus for stabilizing and increasing the yield of natural rubber yarn includes stretching the yarn three times while allowing the yarn to relax intermediate and following the stretching steps. The method is accomplished using a plurality of nip rolls wherein a second roll is caused to travel faster than a first roll or the second roll is larger than the first roll, or both, to achieve the stretch while the yarn is relaxed intermediate three such stretching assemblies.

Abstract: In a shaftless spinning rotor assembly wherein the spinning rotor is the rotor of an axial field motor, an improved transfer of power and improved running properties are attained by forming the stator windings in channels which extend substantially radially in the stator core and are enclosed over at least a portion of their length by magnetically conducting material. As compared with known gap windings, the windings can be placed in multiple layers while at the same time avoiding marked graduations in permeance and in the specific current density so that eddy currents in the rotor can in turn be reduced and rotor heating remains within reasonable limits. The stator is preferably formed of multiple component parts which allows optimized selections of materials.

Abstract: An improved self-lubricating bearing arrangement for gear pumps utilizes a system of material feed channels and reservoir pockets to divert a portion of the material being pumped from the pressure side of the intermeshing gears to lubricate the gear-supporting shafts within the bearing arrangement. At each gear shaft, a linear material feed channel is formed in the radial face of the bearing between a pressure relief recess and an axial opening supporting the shaft and a parabolic reservoir pocket is formed within the bearing opening adjacent the shaft to apply diverted polymer to the shaft. Each material feed channel and reservoir pocket is polished to a mirror finish to minimize any tendency of suspended additives in the polymer from adhering to or collecting within the channels or pockets, thereby to prevent unusual or localized wearing of the gear shafts.
