Granted: 1991-05-02
Abstract: Known cross-winding devices have a strap that moves back and forth a support (5) with a thread guide (7). The support (5) has hydraulically or pneumatically driven clamping means. To obtain cross-wound bobbins, the gripper shuttle drive is provided with a spring (18) that goes through its dead centre when the gripper shuttles (10.L, 10.R) are moved. The gripper shuttle drive is actuated in the stroke reversal areas by fixed stops (23.L, 23.R). The fixed stops can be moved in the direction of the stroke, effecting an aspiration and an oscillation. The strap (1) can extend over several winding stations connected each to a support (5) and thread guide (7).

Granted: 1992-04-08
Abstract: In the apparatus, one switch (1a-1c) is provided for each phase (R,S,T), via which a first input variable (UR, US, UT) of this phase (R,S,T) is in each case supplied to an evaluating unit common to all phases. Each switch (1a-1c) is controlled by modulators (2a-2c). In this arrangement, the active power is measured when the switch (1a-1c) of each phase (R,S,T) is driven by the modulators (2a-2c) with a duty ratio which corresponds to the difference between the duty ratios derived from the two input variables (IR, IS, IT) of the two other phases (R,S,T). This makes it possible to measure reactive power without phase-rotating elements. <IMAGE>

Title: Thick film electrically resistive tracks
IPC: H05B3/26
Filed: 1988-02-23
Granted: 1992-04-29
Abstract: The inventor has found that, irrespective of track thickness or the material of which the track is constructed, the optimum track width for a thick film heater track is in the range of from 1.2mm to 2.1mm. Further advantage accrues in that for a given resistance the track is longer and may be conformed to a pattern to give improved temperature distribution. A heating element is also provided, comprising a plurality of thick film electrically resistive tracks (8) applied to the surface of an electrically insulative substrate and switching means (10) for selectively connecting one or more of said tracks to a power supply. The resistance and hence the operating temperature of the heating element may be varied by changing the track or tracks (8) connected to said switching means (10).

Title: Uninterruptible power supply
IPC: H02J9/06
Filed: 1988-09-09
Granted: 1993-07-28
Abstract: A UPS system includes a mechanical backup input line isolation switch (104) to provide mechanical isolation between a primary energy source connected to the input line (101,102) and a secondary energy source (120) upon detection of a failure of an electronic isolation switch (107) normally providing isolation between the input line and the secondary energy source. Detection of such a failure is accomplished by means of a dummy load (150) which is connected across the input line. Its impedance is sized to permit a small low level of current flow, above normal leakage current levels permitted by a functioning semiconductor electronic line switch, if energy is reverse coupled from the reserve energy source via the failed electronic line switch, without draining significant power from the primary energy source when the UPS is normally operative and deriving power from the primary energy source. A power flow direction sensing circuit (151) detects the direction of power flow at the input to which the primary energy source is connected to the UPS, and a control circuit (152) responsive to the power flow direction sensing circuit disconnects the input from the primary energy source, if reverse power flow is detected, by activating the mechanical switch.

Abstract: Ground fault detectors commonly interconnect secondary windings of the phase current transformers of a source (N1, N2, N3) into a summing circuit. This circuit will produce a zero output when there is no ground fault condition and will produce on a non-zero output if a ground fault condition exists. A problem exists in that a ground fault detector is not easily connected to an existing system. A solution to this problem is an add-on ground fault system including a module (10) readily connected to the distribution line (N4, N5, N6) and to the associated breaker (STS).

Title: Process for microinjection into living cells and apparatus therefor
IPC: C12N15/89
Filed: 1989-02-16
Granted: 1993-01-27
Abstract: In the microinjection of liquids or suspensions of substances into living cells, a stage and a needle, which is movably mounted and inclined with respect to the latter, are connected together so as to be movable relative to one another. The cells are located in a culture vessel on the stage. The needle is adjusted, by moving in a plane z1 which is parallel to the stage above the cell material, with its tip as pointer above a cell so that the tip of the needle is located exactly over the required injection site. Then the needle is moved backwards, depending on the angle of inclination of the needle to the said plane in a direction which is determined by the direction of the needle in its projection onto the plane, by a distance which is so long that, at the end of the backwards movement, the needle is in a position in which the extended axial direction intercepts the cell at the required injection site. The needle is then moved axially to puncture the cell, after which the direction of movement of the needle is reversed.

Granted: 1992-06-17
Abstract: For bending hollow distance profiles (2), in particular those filled with a desiccant, preferably for panes of insulating glass, the profile (2) can be advanced during bending and a bending tool (4) can be moved towards and away from it, oscillating with respect to the abutment (3), the profile (2) expediently being advanced during the moving away of the bending tool (4) and a point on the profile (2) adjacent to the previously bent point being acted upon and bent during the next movement of the bending tool (4) towards the abutment. A very wide variety of arcs and radii of curvature can thereby be produced depending on the speed of advance of the profile and the bending frequency or also bending stroke of the bending tool.   <IMAGE>

Abstract: Dual pyrometric detectors (10,12) and method measure the temperature of a remote heated object (17) in the presence of ambient radiation. One detector (10) measures emitted radiation from both the remote object (17) and from the environment, and the other detector (12) measures radiation predominantly from the environment alone. The output signals from the two detectors (10,12) are processed electronically to yield the detected radiation from the remote object alone. The result can then be electronically processed to display the pyrometrically-measured temperature of the remote object.

Abstract: A method and apparatus are described for preventing a dual deck video recorder from being used to record a copy-protected video signal. A switch (43) is included on the recorder to indicate whether a video signal input to one of the deck locations for recording originates externally of the machine or internally at another deck location. Recording is prevented whenever the switch indicates that the video signal originates from the other deck location if the video signal at such location includes a selected copy-protect signal. If a video signal to be recorded comes from externally of the machine, copying of the same is prevented if (1) the video signal includes the copy-protect signal; or (2) the video signal to be copied is the same as the play back video signal and the latter has the selected copy-protect signal.

Abstract: Mécanisme de commande du débit pour réglage de chenille (34), qui détermine quelle est la tension optimale ou ''fléchissement contrôlé'' dans la chaîne à chenille (28) d'un véhicule de type à chenilles (10). Un piston (70) et une soupape correspondante (86) commandent le débit de fluide sous pression vers un cylindre de réglage de la chenille (48). Le mouvement du piston (70) tend la chenille (28) sans aucun fléchissement notable (''S'') et la rétraction par la suite du piston (70) permet d'obtenir la tension appropriée de la chenille avec un fléchissement de chenille optimal (''S''). L'opérateur du véhicule commande, depuis son poste (16), l'alimentation du piston (70) et de la soupape (86) en fluide sous pression. Les opérations traditionnelles de réglage de la chenille nécessitent un temps et un effort considérables et sont souvent déplaisantes, c'est pourquoi le réglage est souvent négligé, le résultat étant une usure plus rapide de la chenille et des éléments qui lui sont associés. Le présent mécanisme de réglage de la chenille (32) permet de régler avec justesse celle-ci d'une manière aussi simple que rapide.
