Abstract: In a method of printing hosiery, a hose tube is placed over a flat form having a pair of side edges which taper towards each other at a predetermined angle, at least one of these edges being substantially straight. There is then placed over the hose tube on the form a print carrier which is initially in the form of a frustoconical tube but which is flattened along two opposed fold lines. These fold lines also taper towards each other at the said predetermined angle so that the print carrier fits snugly over the flat form. The hose tube is contacted closely between the fold lines and the side edges of the form during a subsequent hot pressing operation, so that a design carried by the print carrier is properly transferred to the hose tube and there is no resultant discontinuity in design in the finished hosiery in those areas.

Abstract: A percutaneous access device (PAD) is provided with a sleeve or separable member which may be detached from the device to enable the culturing of a multilayer fibroblast coating on the member in a stable and undisturbed environment. The member is constructed so that when it is assembled into the device and the device is implanted in a patient, the cultured coating of the member is exposed to the patient's dermis whose fibroblasts will, after a relatively short healing period, merge with the fibroblasts of the coating to form a barrier layer interlocked with the member to prevent epidermal ingrowth or marsupialization of the implanted device.Implantation techniques for further facilitating the formation of the dermal barrier are also disclosed.

Abstract: A modular building structure includes a base formed with an upper planar portion, a lower planar portion spaced from the upper portion to define an interior space therebetween and sidewalls extending between the upper and lower portions and having a convex, outwardly extending shape. A hollow upper shell with outer sidewalls is joined to the base. The base and upper shell are preferably constructed of an inner layer of concrete, an intermediate layer of an insulating material and an outer layer of a waterproof material. A plurality of modules are interconnected by hollow passageways which communicate with the interior of each module to define a continuous open space throughout the interconnected modules.

Abstract: In a compacting machine for compacting a road or the like, the machine has a pre-assembled primary roller drum 4 and another roller drum 20 which perform a different compaction function than that of the primary roller drum. The roller drum 20 is formed by providing a plurality of split roller segments 21, 22. The segments are formed by dividing an annular wall member, at circumferentially different portions in the axial direction into a plurality of split roller segments having a mounting portion. Then the segments are combined together and detachably mounted to the outer surface of the roller drum 4 of the compacting machine.

Abstract: An apparatus for absorbing energy between movable members. The apparatus includes first and second telescopingly engagable members. The second member is formed to be increasingly and forceably engaged with the first member as an external force is exerted on the second member urging it into the second member. In a preferred embodiment, a helical twist is formed in the second member to cause the forced engagement of the first and second members. The helical twist is variable over the longitudinal length of the second member from a first end and increases gradually from the first end to an intermediate portion an then increasingly from the intermediate portion outward towards the second end of the second member. This provides a controlled forced rate build up as the second member is urged into the first member to control energy absorption of the force urging the second member into the first member.

Abstract: An improved dynamic aortic patch is constructed with an elongate semi-rigid shell member having a concave inner surface and a flexible membrane integrally bonded to the outer surface of the shell to define an inflatable and deflatable chamber between the concave inner surface and the membrane. The pumping capacity of the patch is determined by the concavity of the inner surface of the shell member, thus enabling the construction of a patch which may be implanted in the thoracic cavity (small concavity) or in the abdomen (large concavity). A fabric layer bonded to the membrane over the area overlying the outer surface of the shell has a peripheral suture flange projecting freely clear of the membrane, and a temporary shield adapted to overlie the fabric layer may be employed to assure that sutures placed to attach the patch within an opening in the aorta are not inadvertently passed through the membrane.

Abstract: A walk-in shelter providing protection against undesired heat, radiation, gas and water action, as well as mechanical stressing, particularly for data carriers is proposed, in which the walls comprise several different layers. The inner and outer layers are constructed as a closed metal envelope. Between the outer and inner layers is provided a metal supporting frame and between the outer layer, supporting frame and inner layer are provided insulating layers with high thermal insulation and mechanical strength. All the layers are set up independently of one another, are self-supporting and not mechanically interconnected.

Abstract: An engine deficiency indicator includes a detector for detecting a pre-determined amount of angular rotation of an engine. The detector generates a first signal upon the start of one period of rotation of the engine which enables a counter for counting clock pulses. A second signal from the sensor, indicative of the completion of the pre-determined amount of angular rotation of the engine, disables the counter. A processing unit reads and stores the counter data in a memory. The counter data corresponds to the time required for the engine to rotate through a pre-determined amount of angular rotation. At the completion of a pre-determined number of engine rotational cycles, the processing unit analyzes the stored time sequence signals using a discrete Fourier transform analysis and/or an autocorrelation analysis to generate a manifestation of deficient engine operation. A display connected to the processing unit provides a visual or audible indication of efficient or deficient engine operation.

Abstract: A retractable backlight apparatus for vehicles includes first and second pairs of links, each being pivotally connected at one end to the interior vehicle body structure. The opposite ends of each of the first and second pairs of links are pivotally connected to upper and lower portions, respectively, of frame members attached to the side edges of the backlight panel. A tab is mounted centrally on the bottom portion of the backlight panel to enable the backlight panel to be urged downward from a raised position to a storage position recessed within the interior of the vehicle structure during which movement the first and second pairs of links guide the backlight panel downward into a substantially vertical orientation within the interior of the vehicle. Alternately, a drive motor rotates a pair of transversely extending output shafts, each having a drive gear mounted thereon. The drive gears drive sector gears rigidly attached to the second pair of links to automatically raise and lower the backlight panel.

Abstract: The invention relates to a turning mechanism for driving in or extracting piles by means of tangential rotary blows being imparted by a rocker arm equipped with balance weights and arranged in a rotary manner relative to the pile. In order to render superfluous the hitherto necessary noise-damping, additional damping means, damping members made from an incompressible, elastic material are used, which are placed in recesses in at least one stop of a pair of stops in such a way that there is a deformation, particularly at right angles to the impact direction, which is within the elastic limit of the member and prevents direct contact between the stop pairs. These members are arranged on all parts of the rocker arm which, in operation, form noise sources.
