During the measurement of the length of filamentary materials, for instance a yarn, which is wound into a cross-wound package which is driven by a grooved drum, appreciable errors arise because there is not taken into account slippage. Therefore, with the present method during the winding operation the slip, which is governed by the relationship of the circumferential velocities of the grooved dru...

The invention relates to a novel process for the use of a transverse axial tomo-scanner in such a way that it can be used for carrying out cinedensigraphy. Instead of measuring the different projections of the cross-section during examination as a function of the different angular positions of the radiation absorbing device, the same projection (i.e. with a fixed device in the plane of the section...

A rotatable processing bowl-type apparatus for separating blood components where a plurality of flexible umbilical tubes are positioned to establish communication with a processing bowl at one end thereof. Certain segments of each of the cables are stiffer than other segments of the same cables for improved life and performance. Also, outer portions of portions of the cables are impregnated with s...

In a vehicle-mounted navigator, a control unit reads map data from a memory unit and displays a corresponding road map on a CRT display unit. In response to signals from a distance sensor and a direction sensor, the present position in relation to the running of the automotive vehicle is computed to display by superimposition the present position on the road map display of the display unit. When t...

A ribbon lap unit contains support shafts for receiving and supporting a lap, a web transport means in the form of a web drafting mechanism, a web diverter, a diverter plate arrangement and a web collecting element. A web unrolled from the lap is fed through the web drafting mechanism and around the web diverter onto the diverter plate arrangement and thereafter onto the web collecting element. By...

A thread catching ring structure for the chuck of a filament winding machine comprises an axially-extending knife element (36), a guide surface (26) to lead a thread under the knife element and a clamp ring (42, 44) to clamp the thread against the underside of the knife element. The clamp ring has a first flange (42) by means of which the clamp ring is secured in catching ring structure and a seco...

PURPOSE:To make it possible to exhibit a desulfurizing effect using inexpensive matterials and to obtain an amount of sulfur dioxide gas evolution similar to that of kerosine, by forming a carbonaceous fuel containing Ca(OH)2, CaCO3 or dolomite and K2CO3. CONSTITUTION:100pts.wt. carbonaceous fuel is blended with 3-20pts.wt. desulfurizing agent comprising at least one compound selected from among C...

A releasable toe holder or toe jaw for ski bindings having a sole holder movably mounted transversely with respect to the lengthwise direction of the related ski. The sole holder is retained in a normal position by a spring element and following a limited transverse movement thereof is returned back into such normal position by said spring element. The sole holder has a pedal intended to engage be...

PURPOSE:To prevent seizure and excessive wear by forming unevenness at the outside surface of a planet gear supporting pin or the bore on the planet gear side, and by encapsulating lubricant there. CONSTITUTION:A groove 13 to form unevenness is provided at the outside surface 2a of a supporting pin 2 for a planet gear 1. The groove 13 is in communication with an oil hole leading from the end face ...

Disclosed is a coating composition rapidly curable at room temperature in the presence of a vaporous tertiary amine catalyst which coating composition is ideally suited for coating reaction injection molded (RIM) urethane parts, upholstery vinyl, and sheet molding compound (SMC). The flexible coating composition of the present invention preferably comprises an aromatic hydroxyl-functional condensa...

This safety-binding assembly for fastening a boot (4) to a ski (1) comprises at least one front binding or stop (2) and a rear binding (3). The front stop (2) includes a sensor for sensing the longitudinal force (F2) exerted by the boot (4) on this stop (2). This sensing operation acts on the locking mechanism of this stop (2) by reducing the resistance thereof to lateral release in order to compe...

There is disclosed a transparent slippery biaxially stretched polyester film characterized by satisfying the relations represented by the following formulas after being biaxially stretched and heat-set: 0.155 (6) DELTA H

A data processor (2) including a watchdog timer (8) comprising: a first memory (4) holding a primary operating routine for cyclic execution during operation of the data processor, an address bus (6) for addressing locations in said first memory means, a timer (10) for continuous operation during operation of the data processor and for effecting a system reset in response to the timer reaching a pr...

A drill is described having a metal bit carrier part on which a sintered metal bit is placed. The bit possesses at least one enclosed helical cooling channel which continues in alignment into a corresponding cooling channel in the bit carrier part. This drill is particularly characterized by very great mechanical and thermal stability, which is not adversely affected in any way by the system of co...

The substrate of conventional reagent test devices is replaced by polyester screen material having a nominal filter rating of from about 80 to about 130 microns such that liquid present in the reagent matrix material of the test device is retained therein and prevented from running over onto other reagent matrix areas present on the same reagent test device.

Electrical contact materials based on AgCdO with CdO as the main active component have proven to be particularly advantageous for low voltage switchgear in the power industry. However, when switching AgCdO contact materials, CdO, which is classified as toxic, can escape into the environment through burn-off. It is important, therefore, to keep the CdO content as low as possible in the contact mate...
