Abstract: POLYAMIDE SPIN-TEXTURE PROCESS                   ABSTRACT OF THE DISCLOSURE           A spin-texture process for producing polyamide yarns is described in which a freshly extruded yarn is passed between two pairs of rotating rolls and then collected.  The second pair of rolls (draw rolls) is driven at a peripheral speed greater than that of the first pair of rolls (feed roll and its associated separator roll).  The feed roll is maintained at  a given temperature which is correlated with other processing conditions to impart a desired level of latent crimp to the yarn.  Yarns prepared by the process have a potential bulk of between 10% and 50% and are particularly useful as carpet yarns.

Abstract: A method of measuring the quantities of material in a first coating layer applied to cardboard or an equivalent base material as well as in a second coating layer applied to said first coating layer, comprises the steps of directing a primary X-ray radiation against the second coating layer so as to excite a characteristic fluorescence radiation in the first coating layer and measuring the intensity of said fluorescence radiation be means of a detector placed above said second coating layer, whereby the measurement of the quantity of material in the second coating layer is based on the absorption of the primary X-ray radiation and the fluorescence radiation while traveling through the second coating layer. The measurements in connection with the process of coating are carried out by measuring the quantity of material in the first coating layer before applying the second coating layer by irradiating the first coating layer with a primary X-ray radiation so as to excite a characteristic fluorescence radiation in the first coating layer itself and by measuring the intensity of this fluorescence radiation with a detector. The quantity of material in the second coating layer is measured after the application of this layer to the first coating layer by utilizing the value of the intensity of the fluorescence radiation from the first coating layer as measured before the application of said second coating layer.

Abstract: GUARDED RAZOR BLADE ABSTRACT OF THE DISCLOSURE A razor blade having guard elements deposited in recessed guard seats formed in the cutting edge and flanking surfaces of the blade. The guard elements may be deposited by electrochemical plating and their retention on the blade is enhanced by the reces-sed seats formed in the blade surfaces. The guard seats extend rearwardly from the blade edge a significant distance and may be interconnected by a transversely extending locking guard seat into which guard element material is also deposited. A method for applying the guard elements to the blade comprises applying a photoresist material to the blade edge and adjacent region, fixing a photographic image on the photoresist material in accor-dance with a predetermined guard element pattern, removing a portion of the photoresist material in accordance with the pattern and etching the underlying blade to form the guard seats. There-after the guard elements are deposited in the guard seats as by electroplating and the remaining photoresist material is removed to expose the blade edge and guard elements.

Abstract: A B S T R A C T      Initial opening movement of a drawer in a cabinet by cam action raises a locking bar to lock the other drawers closed.   In so doing the locking bar rotates a pinion having an arm which stresses a spring carrying it past an over-centre position to maintain the bar in locking position while the moving drawer travels to the fully open position.     The end of the closure of this drawer by cam action returns the bar, arm and spring to their initial state.  A key-lock mechanism can raise the bar to lock all the drawers shut.          If the cabinet is tilted forward substantially, gravity causes a ball to run to a position to hold the pinion against rotation thereby preventing all the drawers from automatically becoming locked due to the bar running to the locking position under gravity or inertia.

Abstract: ABSTRACT            A normal force applicator and removal apparatus which applies, varies and removes force applied to the top of a document stack where documents are being fed, i.e., by a shingler wheel type document feeder, (also termed combing wheel or wave generator) in order to generate a shingled stack of documents for subsequent processing.  The shingler wheel is adjustable so that it can be centered for document stacks of multiple lengths.  In order to shingle documents at a practical and predictable rate, i.e., maintain a shingled stack of documents, and to avoid skewing of the documents as they are shingled, the normal force is varied as a function of the thickness of the document stack decreasing as the document stack is depleted, and the normal force is applied symmetrically from the center of the shingler wheel to either side thereof.  This symmetrical force distribution is maintained throughout the range of adjustment of the shingler wheel.
