Title: Cleansing control apparatus
Inventor: TANAKA EIICHI
IPC: E03D9/08
Filed: 1991-08-29
Granted: 1996-07-16
Abstract: For use in a toilet, a cleansing control apparatus comprises a device for projecting a cleansing fluid, and a device for controlling the position where the fluid from the cleansing fluid projecting means hits an aimed part of the user's rump.  A monitor part monitors whether or not the fluid from the projecting device is supplied to the aimed part and outputs an image signal.  A control device outputs a control signal to the device for controlling the position to determine the position of the aimed part to be cleaned on the basis of the image signal from the monitor part.  As a result, it is possible to project a medication, cleanser, toilet water, etc. different from the cleansing water from a second fluid projecting means, and the aimed part can be properly treated, for example, damage to the aimed part can be healed or protected.

Title: Torque balancing device for rotary snow ploughs
Inventor: MOETTELI PAUL
IPC: E01H5/04
Filed: 1991-12-05
Granted: 1995-10-24
Abstract: A rotary snow plough includes a ploughing drum, a running gear and a motor drive. A holding-down member is connected to the running gear and is arranged in front of the ploughing drum.  The holding-down member includes upwardly directed holding-back surfaces.  During operation, the rotating ploughing drum creates an upward reaction force, and snow lying above the holding-down surface creates an opposing downward reaction force.  The effect developed by the holding-back surfaces is greater, the greater the upwardly directed reaction force, which arises from the quantity and quality of the snow.

Granted: 2002-05-07
Abstract: A near-infinity image display system (10) has a convex-faceplate cathode ray tube (12) positioned with respect to a concave mirror (14) such that the cathode ray tube (12) is in front of the center of curvature (16) of the mirror (14) and so that the mirror (14) reflects a near-infinity image of the visual display surface to an eyepoint (20) of an observer located below and in front of the center of curvature (16) of the mirror (14) and below the cathode ray tube (12). The cathode ray tube (12) is positioned at a height above the eyepoint (20) of the observer so that it does not interrupt the vertical field of view (24) of the image reflected to the eyepoint (20) of an observer. The concave mirror (12) may be a spherical, ellipsoidal or toroidal mirror. A multiple-display system (30) may be used to create a mosaic reflected image. In the multiple-display system (30), the convex faceplates of cathode ray tubes (12) are placed side by side, and optimally spaced apart at an angle (35) to provide a near-infinity mosaic reflection to an eyepoint (20) of a single observer or eyepoints (40) and (42) of multiple observers. In the multiple-display system (30), multiple observers are spaced apart a distance (41) that optimizes independent viewing of the near-infinity image by each observer.

Abstract: A mechanism for dolls which allows for crying and move-ment of the lips.  The mechanism includes a control cir-cuit and timing element which is connected to a switch placed in the mouth of the doll, a magnetic field detec-tor placed in the proximity of the mouth, a voice appa-ratus, and a motor attached to a mechanism for moving the lips.  The latter mechanism consists of an eccentrically mounted shaft which is attached to one end of a spring having its other end connected to a piece that ends in the shape of an arrow head connected to the doll face in the proximity of the mouth of the doll.  A pacifier in-serted in the mouth of the doll, opens the switch to main-tain inactive all the devices.  If the pacifier is re-moved the voice device is activated.  A bottle having a magnetic element can be inserted into the mouth, and operates the magnetic field detector to start the motor and operate the lips.  Upon removal of the bottle the whole mechanism stops; the timing element starts and after an interval the voice device reactivates.

Title: Rapid deployment system for recovering oil from beaches
Inventor: WHYTE GARY R
IPC: B09C1/00
Filed: 1993-04-06
Granted: 1997-09-23
Abstract: A rapid deployment system for recovering oil from beaches includes an articulated vehicle (20) for propelling and suspending a vacuum head (22) above a beach (26) or the like. A selected area of the beach is irrigated with sufficient quantities of water to saturate the selected area. Oil deposited on the beach is driven to the surface. A sufficient quantity and velocity of air moves over the surface beneath the vacuum head (22) to develop a water column (32) upon which resides a frothy foam mixture of air, water and oil which is drawn into the head (22). In the vacuum head, the velocity of the air flow is suddenly and significantly reduced above a fluid sump (50) wherein entrained oil and water droplets fall into a sump for processing outside of the vacuum head (22). A metal auger (56) can be provided within the vacuum head (22) to pump oil from pools and separate entrained oil droplets from the high velocity air flow. A special terrain vehicle (20) which propels and supports the vacuum head (22) is modular and can be transported by helicopter with the entire system.

Abstract: Abstract An Arrangement with a Plurality of Surge Arresters In an arrangement with a plurality of surge arresters (1, 11) that are arranged so as to be coaxial and are connected to common conductor rails (5, 20, 22) by connecting lines (4, 17, 18, 19), the first connecting lines (4) extend essentially radially away from the longitudinal axis of each surge arrester (1), in a direction that is away from the position of the exhaust openings (2, 3) on the periphery of the surge arrester (1).            Thus, in the event of an arc, the current flowing through the connecting line (4) generates a magnetic field that pushes the arc away from the surge arrester (1).  The exhaust openings (2, 3) on each surge arrester (1, 11) are so positioned that the arc is not formed in the area between two adjacent surge arresters (1, 11), and is pushed away from the surge arrester by the components forces of the magnetic field.  In addition, the present invention provides that the direction of the current in the connecting lines subtends an angle of less than 90° with the common conductor rails, so that the current in the common conductor rails also contributes to generating the desired magnetic field.
