Abstract: A sheet-metal strip provided with mutually staggered cuts is conveyed continuously at a first speed through a first conveying apparatus (23) and at a second speed, increased as related to the first speed, through a second conveying apparatus (24). Thereby, the strip section (21) freely traveling between the first and second conveying apparatus (23, 24) is stretched with the formation of a three-dimensional expanded grid structure. The process permits a continuous, rapid production of expanded grids of high precision and uniformity, especially with regard to mesh width and grid height.

Abstract: A valveless blood conduit for pulsatile cardiopulmonary bypass pump constructed and arranged to provide a surge chamber, a pumping chamber and a reservoir portion, externally valved for use in a pre-load responsive pulsatile pump. The blood conduit precludes the necessity of employing a large volume venous reservoir in a cardiopulmonary bypass system employing a pre-load responsive pump, thus reducing a patient's blood to exposure to large air-blood interfaces and large non-endothelial surface areas.

Abstract: A synchronizing circuit comprises a controllable timer (9) and a PN-code generator (10) controllable thereby with at least three outputs (11.1, 11.2, 11.3), for the production of at least three PN-code signals phase-shifted with respect to one another. The PN-code signals phase-shifted with respect to one another are correlated, in parallel correlation paths, with the received signal. Upon the presence of a time drift, the phase position of the trailing PN-code signal, for example, is changed so that this signal is now leading. Thereby, the control range is shifted. At the same time, reassignment is effected between the correlation path and the demodulating output in such a way that in all cases the correlation path that is in the middle with respect to time and that has the maximum correlation power is utilized for demodulation.

A motor driven strap is connectable to the filled tote bin for pulling the produce filled bin off the pallet and into the cabinet. The tote bin is provided with a false or movable bottom engageable by an elevator mechanism positioned in the cooler for maintaining the level of the produce in the bin at a position near the top of the bin, so that the customer can see the produce when walking by the display area and can easily reach the produce in the bin.

Abstract: A double acting pump having inlet and outlet poppet valves clamped to the pump housing in proximity to an inlet manifold and an outlet manifold. The end portion of each cylinder in the double acting pump is provided with a sloped wall to prevent debris in the pumped fluid from becoming stuck in the pump cylinder. Each poppet includes a valve housing having a spring biased valve head slidably mounted therein and engageable with a removable valve seat. A stem is connected to the valve head and extends through an end wall of the valve housing to the exterior thereof to function as an external indicator rod to indicate the position of the valve head within the valve body. A handle is connected to the stem so that the stem can be manually pulled to lift the valve head from the seat to check the operation of the poppet valve, and a disc is mounted on the stem a predetermined distance from the end wall when the valve is in the closed position so that the wear between the valve seat and head can be obtained.

Abstract: A retaining member on a handle for the exchangeable attachment of an interdental brush (29) exhibiting a fastening element (36) with transverse element (37) has a recess which is designed so that the interdental brush (29) can be introduced in the direction of its longitudinal axis, with the transverse element (37) leading, into the recess (34) and can be locked in place in the latter especially by being folded over.

Abstract: In an accumulator housing for brake system fluid pressure a resilient bulb has a portion expandable by fluid pressure inserted in a sleeve which prevents radial expansion of the expandable bulb and allows only expansion of the end wall thereof toward the bottom wall of a bore in the housing in which the sleeve is inserted. This expansion of the end wall only is enhanced by a coating of lubricant on the inside surface of the sleeve. A pair of discs inside the bottom of the sleeve are normally maintained in contact between the end wall of the expandable bulb and bottom wall of the bore by disc springs connected therebetween with bosses on the respective discs extending toward each other through the inner bores of the springs and terminating in spaced apart stop surfaces. The stop surfaces move into abutment with each other on expansion of the end wall under pressure to prevent further compression of the springs and further expansion of the bulb thus prolonging the life of both members.

Abstract: A drive train suspension system for a manure and compost treating vehicle wherein a linkage assembly is connected between the vehicle drive train assembly and the vehicle frame, on each side of the vehicle frame, so that the vehicle frame is articulately connected to a vehicle drive train assembly on each side. Fluid motors are connected between the vehicle frame and each drive train assembly so that the position of the vehicle frame relative to the drive train assembly can be selectively varied to thereby minimize potential damaging stress imparted to the drive train assembly by the lateral movement of the drive train relative to the vehicle frame, and to raise the vehicle frame to a selected elevation above the ground and/or maintain the vehicle frame substantially level.
