This invention provides a method for joining textile yarns to restore their continuity each time this becomes necessary in a winding unit, by means of a joining device which operates by means of several successive steps, one following another, to achieve a continuous connection, in said method the individual operations involved in the joining being independent of each other and being autonomous an...

A centrifuge apparatus is used for collecting white blood cells (WBC), primarily mononuclear cells, from whole blood stratified into layers. A thin mononuclear (MNC) layer is formed at the interface of red blood cells and plasma. A barrier is positioned in the separation vessel of the centrifuge at a location to intercept the thin layer. MNC fluid is allowed to pool behind the barrier before colle...

A permanent magnetic ring (20) is located in an inlet bore (19) of a housing (12) and preferably has a plastics material labyrinth seal (22) which serves as a flow calming device to prevent re-suspension of solids captured by the magnet.; Das Hydraulikventil (10) weist in seiner Eingangsöffnung (19) für das Hydraulikmittel einen ringförmigen Permanentmagneten (20) und vorzugsweise auch eine Labyri...

A control coefficient, or ratio, for the actual and intended values is obtained, based e.g. on separation distances, relative speeds (V). The control comprises a relative speed measurer linked to the acceleration or slowing-down actuator e.g. by accelerator, engine torque, vehicle speed. The distance reduction coefficient = d/dm, relates separation distances and aimed-at time interval reduction be...

The system has a pump source (100) for generating optical pump pulses of a predefined duration and a signal source (130) that generates optical signal pulses. An optical arrangement (106) receives and combines the pump and signal pulses to produce combined optical pulses. A parametric amplifier (170) containing a quasi-phase adapted crystal that receives the combined pulses and amplifies the signa...

The relative spacing regulation device compares the detected distance of the vehicle from a preceding vehicle with a required spacing dependent on the relative velocity for selective acceleration or braking using a number of alternate braking devices, selected via a relative spacing control. A warning device is activated when the required retardation is above a maximum value, or when the relative ...

Microcellular polyurethane elastomers having sharply reduced or virtually no urea linkages may be prepared without resort to organic physical blowing agents by frothing a frothable mixture containing isocyanate reactive polyols and chain extenders, and a frothable isocyanate component. The isocyanate component is derived by reacting a stoichiometric excess of a di- or polyisocyanate with a polyol ...

Es wird eine Anordnung und ein Verfahren zur Ermittlung einer räumlichen Position eines Objekts auf thermischer Basis dargestellt, bei denen ein bildgebender thermischer Sensor ein thermisches Bild der Umgebung detektiert und entsprechende Signale an eine mit dem Sensor gekoppelte Verarbeitungseinheit abgibt. Die Verarbeitungseinheit nimmt die Signale auf, wertet das Bild hinsichtlich einer thermi...

The volume of the separated portions (24) of the melt stream is adjusted to a nominal size with a tight tolerance by variation of the gas pressure, the melt temperature and the sonotrode frequency. The bar (12) and the separated portions - prior to their entry into the cooling medium - are flooded with a protective gas. The separated portions within the entry region are maintained at a temperatur...

A fall-protected autonomous travel system with area markers is disclosed. Area markers are arranged in the travel area of a mobile unit. The mobile unit contains a spatial scanning device with a sensing range in which the travel area of the mobile unit is scanned in the direction of travel of the mobile unit and area marks located therein are sensed. A program-controlled control device brings the ...

Disclosed is a method for preparing an intact stuffed lobster product utilizing raw roe from gravid female lobsters blended with raw meat extracted by aid of protease enzyme and vacuum techniques from the deep shoulder section of uncooked lobsters. In a first step, lobsters killed by hot water immersion and chilled by cold water immersion are subjected to evisceration of the anterior visceral cavi...

An application module (A) running on a host computer in a computer network is failure-protected with one or more backup copies that are operative on other host computers in the network. In order to effect fault protection, the application module registers itself with a ReplicaManager daemon process (112) by sending a registration message, which message, in addition to identifying the registering a...

Procedures are provided herein for the optimization of the utilization of crustaceans, e.g., whole lobsters, through the inclusion of under-utilized components. The procedure involves firstly, initiating the detachment of the raw edible deep-shoulder myotomal meat from deep-shoulder cartilaginous skeleton attachment. This may be accomplished either by immersing the head-shell in a solution of prot...

A laser driver utilizes a difference amplifier circuit to produce a servo signal, and a tracking circuit for storing a digital approximation of the servo signal. During a write mode of operation, the tracking circuit produces a stored tracking signal which does not change. This tracking signal is used as the baseline current to which write pulses are added during the write mode. The digital approx...
