Title: Optical waveguide plug connection
Inventor: VAN DEN BERGH HUBERT
IPC: G02B6/38
Filed: 1990-08-10
Abstract: An optical waveguide plug connection for the transmission of high continuous wave light powers from an incoming optical waveguide (5) into an outgoing optical waveguide (15) comprises a metallic plug housing (1) equipped with a metallic centering element (2). The incoming optical waveguide (5) and the outgoing optical waveguide (15) project into the centering element (2), the end faces (13, 23) of the two optical waveguides (5, 15) being arranged opposite each other. The width of the gap (24) is approximately in the range of from 5 to 30 micrometres. The core diameter of the outgoing optical waveguide (15) is approximately one third larger than the core diameter of the incoming optical waveguide (5). The gap (24) is filled with gas. The plug housing (1) is connected to a housing (25) of large surface area which dissipates heat. Using this plug connection, continuous wave powers of up to some 100's of watts in the case of visible to infrared laser light can be transmitted with a high degree of coupling without danger to the end faces (13, 23) of the coupling connection.

Title: High security panic exit system
Inventor: EVANS WALTER R
IPC: E05B65/10
Filed: 1990-08-29
Abstract: ABSTRACT OF THE DISCLOSURE A combined panic exit and combination lock assembly for a security area door including a panic exit device on the door inner side and a high security combination lock   on the door outer side, wherein operation of a panic bar from within the  security  area  concurrently  retracts  both  the latch system of the panic exit device and the lock bolt of the  combination  lock  for egress  from the  security  area.          However, retraction of the panic exit latch system and of the lock bolt from outside the door requires independent unlocking  operation  of  both  the  panic  exit  device  and combination lock.  A primary latch bolt of the exit device is retracted by a rod member and main control link,  and secondary outputs and associated secondary latch bolts are connected to bellcranks.   One of the secondary outputs is connected to the combination lock bolt mechanism and its associated bellcrank  is coupled by a lost motion linking system to the rod member  so that retracting movement is imparted to the coupling link from the rod member without relative motion  between  them  to  achieve  concurrent retracting movement of the latch bolts and lock bolt and relative  lost motion movement of  the coupling  link with respect to the rod member is accommodated upon independent retraction of the lock bolt or the primary latch bolt from outside the door.

Abstract: PROCESS FOR PRODUCING HYDROGEN-CONTAINING GAS               ABSTRACT The production of a hydrogen-containing gas is effected by mixing a hydrocarbon feedstock with steam, a preliminary steam catalytical conversion of the resulting steam-gas mix-ture, followed by a primary catalytical  conversion and a secondary steam-oxygen catalytical conversion. The secondary conversion is carried out with the supply of an oxygen-containing gas mixed with a heat-transfer agent in a volume ratio of the heat-transfer agent to oxygen equal to 0.5:30.0 and heated to a temperature of not more than 900°C. The desired product obtained in the secondary conversion is deli-vered to the primary conversion for carrying out the process of a steam conversion effected by the heat from the desired product.

Title: Coastal stabilization by fluidizing non-cohesive subsoil
Inventor: PARKS JAMES M
IPC: E02B3/04
Filed: 1991-03-04
Abstract: Coastal maintenance, such as for beaches or navigable channels.  Fluidized subsoil, whether from beach enhancement or from clearing a channel if not swept onto a nearby beach (Figs. 1, 2) may be fed into an alongshore current (Figs. 9, 10, 11, 12), or piping, and be transported elsewhere. Water is removed from subsoil underlying a beach (Figs. 13, 14, 16) via first foraminous pipes (71, 73) and is jetted (Fig. 15) via other foraminous pipes (81, 83, 87, 89), interconnected by a non-foraminous pipe (75), into adjacent offshore subsoil to fluidize it. As an alternative to continuous flow, fluidization via a piping array is augmented by sequential timing in a manner resembling peristalsis, to generate lateral flow (Figs. 7A, 7B, 7C; 8A, 8B, 8C). Valve-control means (Figs.  6) opens and closes individually valved water-jetting branch tubes (6; Figs. 3, 4) in accordance with a pre-set pattern of sequence and duration or sensors (3; Figs. 5A, 5B) of fluid flow and/or pressure.
Patent CA-2059935-A1 (CA)
Inventor: STEIGERWALD ROBERT L
IPC: H02M3/337
Filed: 1992-01-23
Abstract: An off-line switching power supply includes an ac rectifier and a dual-output switching converter having one output coupled between the ac rectifier and the input to the dual-output converter in order to provide a high power factor, the other output of the dual-output switching converter providing a do voltage as the power supply output.      The outputs of the dual-output converter are fully decoupled so as to allow independent control of the ac input current and the power supply output voltage. In a preferred embodiment, a full-wave ac rectifier bridge is coupled in series with the second output of the power converter via an input resonant boosting converter. A full-bridge dc-to-ac converter is coupled between the do link and ground for providing an ac signal to excite the boosting converter and for providing another ac voltage through a transformer to an output rectifier to generate a regulated do output voltage.      The amplitude of the regulated output voltage is controlled by pulse width modulation, while active frequency control of the boosting converter is provided to control the amplitude of the ac input current. Alternatively, frequency control of the boosting converter is passive, i.e., depends on the gain characteristics of the boosting converter resonant circuit.      As a result of the complete decoupling of the input boosting converter and the power supply output voltage, the off-line switching power supply is capable of drawing high quality current waveforms from the ac source while producing a regulated do output voltage with fast transient response.
