Patent GB-2257590-A (GB)
Title: Microwave operated automatic door
Inventor: WHITING GORDON S
IPC: E05F15/20
Filed: 1992-06-18
Abstract: An automatic door is operated by a microwave sensor. The sensor is a motion and presence detector 12 which receives Doppler shifted reflected microwave radiation to detect the passage of a person or an animal in a field of view. For motion detection the passage of a person or an animal near a doorway is detected and the doorway actuated in response thereto, to permit the passage of the person or animal thereto. Presence is sensed by detecting "swaying motion" of a person or an animal in a field of view much closer to the location of the sensor as its gain is much lower than that of the motion detection channel. Signals representative of motion 26 and presence 50 are gated through an OR gate 28 to a timer 32 to activate the door opener 36. The motion signal 26 is also used to block 52 the presence signal 50 so that the OR gate 28 receives a stretched presence signal 54 only if the motion signal 26 is absent. The motion signal 26 is detected in a Doppler band of approximately 15Hz to 50Hz. The presence signal 50 is restricted to a spectrum of frequency less than approximately 1Hz by a low pass filter 40. The arrangement allows the door to be kept open for slowing-moving bodies, but closed rapidly behind fast-moving bodies. <IMAGE>
Patent GB-2259200-A (GB)
Title: Ground fault protector
Inventor: YOSHIZAWA OSAMU
IPC: H02H3/24
Filed: 1992-08-25
Abstract: The output voltage from a protective transistor 1 connected between a power supply 20 and a load 30 is detected by a voltage detector 2, and then compared with a predetermined reference voltage by a protection controller 3. When the detected voltage is lower than the reference voltage, the protection controller applies a protection control signal to a protection actuator 4, which opens a switch to cut off the protective transistor. In the event of a ground fault, the detected voltage becomes lower than the reference voltage, and the protective transistor is turned off, thereby interrupting the current supplied from the power supply to the load. The power supply is therefore protected from the ground fault. <IMAGE>

Title: Shuttering system
Inventor: DINGLER GERHARD
IPC: E04G11/48
Filed: 1993-04-02
Abstract: An extruded profiled main beam (11) for a concreting formwork has a plate-like upper wall (16) which projects beyond the side walls (21, 22). The side walls thus set back provide room for dirt gutters (63, 64) on both sides, at the transition to suspension gutters (53, 54) for the connection of further beams (11). Any dirt (concrete milk) which drips down can thus be kept away from the suspension gutters more effectively. Moreover, the dirt gutters have a stepped gutter bottom (73, 74), so that dirt which has penetrated can nevertheless run off unimpeded. <IMAGE>

Title: Knitting parts of knitting machine
Inventor: NANYA TAKANORI
IPC: D04B27/02
Filed: 1994-02-25
Abstract: In knitting parts (a guide, needle, tong and the like in a warp knitting machine) of a knitting machine, an anticorrosion layer (12) formed by wet plating, an intermediate layer (14) formed by dry plating and a hard carbon film (16) formed by dry plating are successively laminated on and covers at least a surface of that portion of a base material (10) formed of carbon steel and shaped to profile the knitting parts, which portion contacts a knitting yarn (18), and a surface of a portion other than the above portion is covered only by the anticorrosion layer (12) formed by wet plating. So, the anticorrosion layer prevents rust and corrosion which would otherwise be produced on a surface of the base material (10) formed of carbon steel, and the hard carbon film firmly sticks to and covers at least the surface of that portion, which portion contacts a knitting yarn, with the intermediate layer therebetween, so that the thickness of the entire film is made small to provide an adequate abrasion resistance without impairing toughness of the base material, thereby markedly improving durability. <IMAGE>

Title: Exploration for petroleum or natural gas
Inventor: ANDERSON ROGER N
IPC: G01V1/30
Filed: 1992-07-27
Abstract: In the exploration for petroleum or natural gas, drilling targets are identified by locating local maxima of horizontal gradient in the top-of-geopressure surface of a region of exploration. The probability of finding hydrocarbon deposits is significantly improved where the drilling targets are local maxima of the horizontal gradient in the top-of-geopressure surface which coincide with local maxima of subsurface heat flow in the region of exploration, particularly where the local maxima in the horizontal gradient of the top-of-geopressure surface is concentrated across major fault offsets and are parallel to the predominant strike directions of the faults. The top-of-geopressure surface may be remotely sensed by performing complex trace analysis on reflection seismic traces gathered for the region of exploration to drive corresponding reflection strength attribute traces. The corresponding reflection strength traces are first smoothed and then subject to further complex trace analysis to derive the envelope amplitudes of the smoothed reflection strength traces, which are referred to as second reflection strength traces. The second reflection strength traces are then analyzed to locate an uppermost distinct subsurface boundary between high and low amplitude components thereof. Such a distinct boundary is then identified as the top-of-geopressure surface for the region of exploration. <IMAGE>
