Title: Control circuit for regulating current flow through a load
Inventor: KATZ HANSPETER
IPC: G05F1/56
Filed: 1989-12-21
Abstract: A regulator controls the DC current flowing through a load, where the current is initially supplied by an AC voltage source and thereafter rectified, the control being proportional to the load current. In one embodiment, the source-emitter potential of a transistor which functions as a control element is changed by means of a current source such that a current of predetermined strength flows through the control element transistor. The control current for the current source is derived from a current sensor in the load circuit. Additionally, a constant gate potential for the transistor control element is obtained through the current sensor. This circuit is preferably suitable for the regulation of the cathode current of travelling-wave tubes.

Inventor: WOLF RICHARD J
IPC: G06F3/0481
Filed: 1990-10-09
Abstract: A computer user interface that comprises a system and methods to provide a control hierarchy, control marking, a hybrid grammar, and resized and/or repositioned dialog boxes. Control hierarchy divides controls, assigns each control a label, displays the labels according to a design hierarchy, and operates on the controls according to a functional hierarchy. Control marking distinguishes controls, via addition of graphic elements or changes in labels--referred to as glyphs. Hybrid grammar simultaneously allows a user to specify operations and data objects in a noun verb relationship or verb noun relationship. Finally, resized and/or repositioned dialog boxes enable a user to select a control that requires selection of data objects that are possibly obscured by the dialog box.

Title: Vehicle riders' helmet having an air jetted shield plate
IPC: A42B3/28
Filed: 1990-12-11
Abstract: A helmet has a chin cover portion formed immediately below a window opening of a front of a cap body.  A recess is formed on a front surface of a shell at the chin cover portion.  A housing covers the recess and opens at an upper end to the window opening therefor.  The housing is secured to the shell.  Air intake  holes are formed at the housing. A distribution chamber and a plurality of air introducing ducts are defined between the housing and a bottom of the recess.  The ducts upwardly extend from the distribution chamber and communicated with a plurality of jet holes.  The distribution chamber of a large volume can be formed without impairing the strength of the buffer liner inside the shell. The air introduced from the air intake holes can be reliably jetted out to the inner surface of the shield plate which closes the window opening, to prevent a cloud forming on the inner surface of the shield plate.

Title: Fiber optic liquid leak detector
Inventor: VALI VICTOR
IPC: G01M3/38
Filed: 1991-03-26
Abstract: ABSTRACT      A precision  liquid leak detector 10 free of mechanical moving parts is disclosed herein.  The  liquid leak detector 10 of the present invention is disposed to measure the rate of change of the volume of a liquid within a container 14.  The leak detector 10 includes  a light guide 16, implemented as an optical fiber, which is disposed within the container 14 and at least partially immersed in the liquid.  The optical fiber 16 includes a fiber core circumscribed by a fiber cladding selected such that evanescent wave loss occurs as a result of immersion of the cladding within the liquid.  The optical fiber 16 is positioned in optical alignment with a laser source 26, which injects optical energy therein.  The leak detector 10 of the present invention further includes an arrangement 24 for measuring the decrease in the intensity of the injected optical energy occurring over a length of the fiber 16 immersed in the liquid. The measuring arrangement 24 then generates an intensity loss signal indicative of this intensity decrease.  The inventive leak detector 10 also includes a network 36 and 38 for  measuring the rate of change of the intensity loss signal and for calculating the rate of change of the liquid  volume on the basis of the change in the intensity loss signal.

Title: Filter candle
Inventor: BEST WALTER
IPC: B01J20/28
Filed: 1991-05-16
Abstract: ABSTRACT         There is disclosed a filter candle which is easily handled and economically manufactured.  The filter candle disclosed in the present invention is especially used for gas filter equipment and consists of an inherently dimensionally stable, especially sintered material.  The filter candle is composed of mutually telescoping filter candle segments. Such filter candle segments are easily handled and not susceptible to destruction.  If individual regions of the filter candle are damaged or clogged, the filter candle need not be exchanged as a whole, merely the particular filter candle segment effected.          The cross-section of the telescoped-apart filtered candle tapers off in one direction.  The segments support each other in a geometrically locking manner and the mutual bracing in the telescoped-apart condition can be implemented by projections forming inward flanges on the lower side and outward flanges at the upper side.

Title: Contactless linking device for interconnection data bus sections
Inventor: MONOD MARIE-ODILE
IPC: G05B15/02
Filed: 1991-05-17
Abstract: ABSTRACT OF THE DISCLOSURE     The device serves to interconnect first and second sections  of  a  a  data  bus  in  order  to  provide  a transparent bi-directional data transmission along the bus comprised of the two sections,  irrespective of the protocol used.   Basically, the device comprises a first transmitter-receiver module at which terminates a first bus section, and a second transmitter-receiver module at which terminates a second bus section. Both modules are disposed   face-to-face   without   contact   and   are electromagnetically coupled.   Each transmitter-receiver module has a circuit for supplying a transmitting coil with a signal modulated by the data to be transmitted and coming from the bus section to which the module is connected,  and  a detector  circuit  for  receiving  a modulated signal from a receiving coil to produce the data to be transmitted to the bus section to which the module  is  connected.     In  each  transmitter-receiver module,   the  transmission  and  reception  coils  are comprised of one and the same flat spiral winding.
