Filed: 1992-09-25
Abstract: Fault gas seals to prevent the ejection of a surge  arrester from a  loadbreak bushing  due  to  the generation of such gas in response to the failure of arrester devices in such surge arrester.  A metal O-ring support  is  bonded  to  the  conductive  insert  of  the arrester housing or added as a retrofit to such housing. Annular grooves in the loadbreak probe are fitted with O-rings which  are  compressed  against  the  support  to provide a gas-tight passage along the probe surface.  An additional  annular  groove  can  be used  to  receive  a fastener to hold the retrofit in position.

Inventor: VIESPESCU DANIELA
IPC: A01G25/00
Filed: 1993-02-05
Abstract: On sait que l'arrosage d'une pelouse se fait actuellement en utilisant l'eau du réseau d'eau potable de la Ville. Des robinets d'arrosage sont normalement installés à l'extérieur d'un bâtiment; il suffit d'attacher des boyaux flexibles auprès de ces robinets et d'ouvrir ces derniers, pour que l'eau commence à sortir par l'autre extrémité du boyau. Celui-ci est normalement connecté à un arrosoir avec des perforations. Dans la présente invention, on n'utilise plus l'eau potable pour arroser, mais l'eau de pluie que nous captons à l'aide de gouttières installées au toit du bâtiment. L'eau de pluie qui tombe sur le toit s'écoule vers les gouttières inclinées; une ou des gouttières verticales réunissent toutes les autres et conduisent l'eau vers un réservoir placé contre un mur et installé sur une base solide. Ainsi, à chaque fois qu'il pleut, le réservoir reçoit une certaine quantité d'eau qui sera, lorsqu'il y a besoin, utilisée pour arroser la pelouse. L'eau sera mise sous pression par une petite installation de pompage (gui comprend une pompe et un robinet). Un réseau de boyaux flexibles ou fixes sera installé à la sortie de la pompe.

Abstract: Seringue à cartouche comprenant une cartouche renfermant un médicament liquide ou une solution analogue et qui est introduite dans un porte-seringue comportant une aiguille injectrice à son extrémité distale; lorsqu'on pousse la cartouche, celle-ci est percée par l'aiguille injectrice et le médicament liquide ou une solution analogue est injectée dans un objet; lorsqu'on pousse le piston de la cartouche et que cette dernière est percée par l'aiguille, le médicament liquide ou autre contenu ne sera pas injecté en trop grande quantité. Plus particulièrement, l'ensemble est muni d'un mécanisme de verrouillage pouvant être libéré: lorsqu'une tige de piston est (15) est poussée, la tige avance en même temps que le corps tubulaire (11) d'une cartouche (10) sans faire bouger le piston (14) à l'intérieur du corps tubulaire (11). Par exemple, dans une première application, lorsqu'une aiguille injectrice (5) perce l'extrémité distale du corps tubulaire (11), un élément d'accrochage (24) est poussé puis amené en contact intime avec la tige du piston (15), ce qui a pour effet de libérer le mécanisme de verrouillage (21), et en poussant la tige du piston (15), le piston (14) est poussé et s'avance à l'intérieur du corps tubulaire (11) refoulant le médicament liquide ou  toute solution analogue par l'aiguille injectrice (5).

Title: Method and system for avoiding selector loads
Inventor: WILLMAN BRYAN M
IPC: G06F12/12
Filed: 1993-02-23
Abstract: METHOD AND SYSTEM FOR AVOIDING SELECTOR LOADS     Abstract of the Disclosure An  improved  method  and  system  for  reducing  the number  of  segment  register  loads  that  occur  during  the transfer  of  control  from  an  application  program  to  an operating  system  routine   is  provided.     In  preferred embodiments  on  an  Intel  80386  processor,  an  application program  and  operating  system  kernel  share  a  code  segment address space and a data segment address space from 0 to 4G. During  the execution  of  the  application  program,  which executes in user mode, a page table is defined to prevent the application program from accessing pages which correspond to the address space of 2G to 4G.  When the application program invokes a system routine, the system routine does not need to load the data segment register since the application program and the kernel share the same data segment.  If an application program does load the data segment register with a selector other than the selector for the shared data segment, then when the kernel tries to  access memory using  the data  segment register,  an exception is generated.   The exception handler restores the selector for the shared data segment into the data segment register and resumes execution of the instruction which caused the exception.

Title: Compression glass lead-through arrangement
Inventor: HORNIG WOLFGANG
IPC: H01L23/10
Filed: 1993-06-17
Abstract: ABSTRACT       The invention relates to the production of a compression glass lead-through arrangement in a metal body.  Compression glass lead-through arrangements of that kind are used in metal housings for semiconductors, in particular integrated circuits. These lead-through arrangements must hermetically seal  off  the  interior of  the housing  relative to  the outside world. For that purpose a glass bead is fused into a bore in the housing and the connecting conductor of the integrated circuit is passed outwardly through the glass. It has now been found that alloys of the systems Cu, Al and Mg, during the cooling operation after the fusing-in procedure exhibit a hardening effect which provides that, with those alloys,  it  is  possible  to  produce  compression  glass  lead-through arrangements which have                 hermetic sealing integrity even after a high degree of thermal and/or mechanical loading. They have a high resistance to fluctuations in temperature and good resistance to corrosion.            (Figure 4).

IPC: H04N1/417
Filed: 1993-08-03
Abstract: An encoding method for digital image data comprising consecutive blocks of data groups having as content binary values always of an equal number of pixels of an image, utilizing a code which indicates that the encoded block is partly equal to the corresponding part of a reference block, the reference block preferably being the preceding block, and identifies the end point of that part of the reference block by reference to transitions in pixel value in the reference block. On decoding, that part of the reference block is taken over in the decoded block.      This encoding method is, in practice, combined with run length encoding and encoding by copying an entire data group in the code.

Title: Method and circuit for selecting tuning of a radio receiver
Inventor: BUSSAN CHRISTOPHER F
IPC: H03J1/00
Filed: 1993-04-19
Abstract: A circuit and method for selecting tuning of a radio receiver to a frequency channel of a set of frequency channels. The radio receiver scans selected control channels and measures the power levels of signals generated upon control channels. Only when the measured power levels (684) of the signals generated upon the respective ones of the control channels are in excess of a certain power level is a communication link attempted to be effectuated with a transmitter of such data signals (696). When a communication link cannot be effectuated, the radio receiver powers down (708) for a predetermined time period, then powers on again (710), and the power levels of signals transmitted upon the control channels are again measured (710). Effectuation of a communication link with a transmitter which transmits a signal upon one of the control channels is attempted if the measured power level on such control channel increases beyond a certain amount.
