Inventor: BERG ARNE
IPC: G02B6/38
Filed: 1989-03-03
Abstract: A fibre optic connector for use under water is described. Each of the two connector parts (1a, 1b) in the device contains a greasy or visco-elastic filling compound (4) which protects the ferrules (2a, 2b) and the centering unit (5), and which is displaced during mating so that light is allowed to pass. When the connector is disconnected, the filling compound (4) is drawn back across the ferrules and centering unit to provide protection again. The compound (4) is chosen so that it can remain exposed to seawater without changing its characteristics or be dissolved or washed away.

Granted: 1993-10-05
Abstract: CONNECTOR SYSTEM                 ABSTRACT OF THE DISCLOSURE    An apparatus  bushing  is  fixed  to  a  support wall  or the wall of the apparatus housing and is electrically coupled to the apparatus within.   A high  voltage  cable  is  fixed to the single leg of a 600-Amp "T" connector and is supported only  by a  bracket  extending  from  said  apparatus  bushing to one of the "T" legs.  A removable pin-and-socket applied link member  selectively  couples  the remaining "T" leg to the  apparatus  bushing  whereby  power  passes  between  the apparatus and  high  voltage  cable  only when  said  link  is present and  isolates  said  cable and apparatus when it is absent.A  novel  operating  assembly  assures proper  contact between  the  link  sockets  and  the  pins  of  the  apparatus bushing  extender  and  the  600-Amp  "T"  connector  and  can be  arranged  to  positively  separate  the  link  assembly.          The  operating  assembly  can  also  be  used  to  install  and remove a cap assembly when the electrical link is not in place.

Title: Hot standby transmitter switching system
Inventor: NISHIMURA AKIRA
IPC: H04B1/74
Filed: 1989-12-15
Granted: 1993-11-02
Abstract: ABSTRACT OF THE DISCLOSURE      In a hot standby transmitter system, each identical transmitters, one of which is a primary and another one 18 a standby, comprises an image-cancel type mixer, which outputs upper or lower sideband waves of a local frequency, according to its internal connection controlled by a switch controller.  The switch controller controls the internal switches and an RF switch, so that the primary transmitter outputs a predetermined primary one of the sidebands and the standby transmitter outputs another sideband, and the RF switch selectively connects the output of the primary transmitter to outside.  The standby transmitter undesirably outputs a small level of the primary sideband though it should be theorectically zero.  This low level primary wave component in the standby transmitter's output allows a reduction in the isolation amount of the RF switch, compared with high isolation amount required in a prior art method where the standby transmitter outputs the primary wave in as high as the primary transmitter level, in order to keep the ratio of power level from the primary transmitter to the power level from the standby transmitter higher than a predetermined requirement level.  The circuit to detect a fall in the output power is simple compared with a complex circuit required in another prior art method where the standby transmitter outputs the less primary wave than the primary transmitter.

Title: Helical conveyor freezer

Granted: 1993-11-02
Abstract: HELICAL CONVEYOR FREEZER                    ABSTRACT OF DISCLOSURE         A food freezer having a thermally insulated enclosure wherein an endless conveyor having a lower loading section, a main helical section and an uppermost unloading section is primarily driven by engagement between its inner edge and the sidewall of a rotatable center cage, which includes a plurality of uniformly spaced apart vertical bars.  The lower end of the center cage can be blocked, and a centrifugal blower is axially located at the upper end of the cage to suck gas from the interior of the cage and discharge it horizontally outward along the undersurface of the top wall so that it flows outward, then downward and, finally, radially inward in an overall generally toroidal pattern through the tiers of the helical belt section where it withdraws heat from and freezes the food products being carried therealong.  Various arrangements, e.g., adjustable restrictors, are illustrated for creating vertical gradients in the radial inflow of gas through the helical section so that the cold gas flows inward at a greater rate in lower regions of the helical section than in the upper region. Cryogen injection devices for spraying a cryogen, such as liquid CO2 or liquid N2, radially inward to impinge upon the food products on the belt, may be located at selected positions about the perimeter and at various vertical levels.  Radial inflow of gas adds to the effectiveness of the impinging spray against the food products; however, the overall freezer construction is also advantageously employed with mechanical cooling of the gaseous atmosphere via one or more heat exchange coils.

Title: Real-time rejection circuit to automatically reject multiple interfering hopping signals while passing a lower level desired signal
Inventor: SKUDERA WILLIAM J JR
IPC: H04K3/00
Filed: 1990-11-21
Granted: 1994-02-01
Abstract: ABSTRACT        A real-time rejection circuit for passing low level desired signals in the presence of one or more strong  interfering signals.  A chirp-Z transform system separates the various frequency components of a received signal into frequency segregated time domain signals.  A power splitter separates the time domain signal into two paths.  One path includes a modulator or switch that is normally biased "ON" for passing the time domain signal.  The second path includes a diode detector that produces pulses of sufficient strength when a strong interfering component is present to override the bias and turn the modulator "OFF" for a sufficient period of time to attenuate the unwanted frequency components in the other path.  The modulator output will primarily contain the low level desired frequency components that are passed through an inverse transform device for producing a frequency domain signal of the desired signal uncorrupted by unwanted signals.

Title: Device for triggering a postage meter machine
Inventor: BERGER ERWIN
IPC: B65H5/06
Filed: 1991-02-19
Granted: 1996-08-06
Abstract: The apparatus comprises two levers (80, 81), which are rotatable around rigid axles (86, 87). Added to this is a third rigid axle (85), which carries the one lower infeed roller (21.2). The upper infeed roller (21.1) is supported at a lever (80) and is springingly pressed against the lower infeed roller (21.2). Letters to be postage metered run in direction of the arrow (52) and thereby press the two infeed rollers (21.1, 21.2) apart from each other up to a maximum width D. The one lever (80) carries a bolt (95) at an arm (94), where the bolt (95) engages into a curved slot (98) of the other lever (81). The bolt (95) freely moves in the curved slot (98)between zero and a width of, for example, 3 mm. In case of a larger width, the bolt (95) impacts at the edge of the slot and presses the other lever (81) in direction of the dashed illustrated deflection position. The release of the postage meter machineoccurs by the release fork (22), which is rotatably attached in an elongated hole (99) of the other lever (81). The respective release point in time is shifted based on the deflection of this lever (81), whereby the imprints of the postage meter stamp occurs later in case of thick letter envelopes, as compared to thin letter envelopes. This effects an improvement of the imprint quality on the letter envelopes.

Abstract: An optical mechanical rotation sensing mechanism for a web-roll (12) rotatably mounted within a cartridge (10) comprises a flange (20) on the web-roll (12), activating means (54, 56) on the flange (20), and an optical sensor (L, 46), outside (44) the cartridge (10), including a beam of light (L) for sensing incremental rotation of the flange (20) and web-roll (12). A movable flag (52) on the cartridge (10) exterior actuates the optical sensor (L, 46) in response to movement of the flag (52) between a first position (Fig. 6), in which the light beam (L) is interrupted, and a second position (Fig. 7) in which the light beam (L) is uninterrupted. A coupling means (58-71), including a light-shield hood (64), couples the flange activating means (54, 56) to the flag (52) for moving the flag (52) between its first (Fig. 6) and second (Fig. 7) positions.
