Abstract: A lighting device, particularly suited for medical examination purposes and suited to be attached to a medical examination device such as a vaginal speculum, includes a power source and a flexible, preferably malleable arm extending from the power source with a nondirectional light source at its end. The arm has a small diameter allowing it to be used with medical instruments without blocking the viewing area provided by such instruments and allowing it to be inserted through tubes commonly used in medical, dental, or veterinary procedures. For medical, dental, or veterinary use, the outside temperature of the light source is controlled to keep such temperature below a temperature that would damage living tissue.

Abstract: A roof top pipe support includes a base having a substantially flat bottom to rest on the roof. At least one, and preferably a pair of raised portions provide a pair of stud-receiving holes in the base to receive and direct studs, preferably threaded studs, upwardly from the base. The raised portion also can receive and support a pipe supporting roller. A pipe support such as a pipe supporting roller or a strut also can extend between upwardly extending studs and be adjustably secured to the studs so the height of the pipe support can be adjusted. Either pipe support can be used depending upon conditions and the height of the support needed.

Abstract: A latch cover is secured over a latch to be protected by the lock which locks the latch, and the latch cover restricts access to the latch to reduce the chance of tampering with the latch. The latch cover includes a cover plate sized to cover a substantial portion of the latch and lock when held in a position in front of the latch. Holding plates extend from the cover plate over the sides of the latch where a lock member of a lock locking the latch extend. Such lock member extends from the opposite sides of the latch and through holes in the holding plates to secure the cover in place. Side plates preferably extend between the holding plates to form a box structure to more fully cover the latch. Notches in the side plates receive items extending into or from the latch and help position the cover. The cover allows access to the lock so the lock and latch can be opened when desired and the cover removed.

Abstract: An axial actuator for actuating a valve by rotating the shaft of the valve includes an outer enclosure forming an interior space having an inner enclosure therein. A piston is linearly moveable within the interior space of the outer housing to divide such interior space into two chambers, one of which includes the inner enclosure. A rotation device is positioned at least partially within the inner enclosure and is interconnected with the piston for rotating the valve shaft in response to linear movement of the piston. The rotation device preferably includes a rotation bevel gear having a hub adapted to receive the valve shaft to be rotated and compound pinion gears each with a bevel pinion gear which mates with the rotation bevel gear and a spur pinion gear which mates with racks which extend from the piston. Movement of the piston causes movement of the racks which rotate the compound pinion gears. This, in turn, rotates the rotation pinion gear and the valve shaft.

Abstract: A parking guide for a vehicle made of a telescoping antenna attached to a mounting bracket wherein the antenna is extended to allow the driver to see where the front or rear of a vehicle is in relation to other objects while parking.

Abstract: In an image resolving detector arrangement, an image of an object scene is generated by an imaging optical system. Radiation from a respective one of several adjacent image elements of an image area associated with the detector element is directed consecutively onto each of the detector elements by an image element selection device. Herein the image element selection device is formed by a micro-light stop raster, which is arranged in an image plane and moveable step by step in this image plane, and which, in each position, allows only radiation from a part of an image area associated to a detector element to pass onto the detector element. Thereby, the resolution of the image resolving detector arrangement is improved.

Abstract: The invention relates to an apparatus for treating water by means of an electric field. An anode and a cathode are arranged in a treatment chamber. Seed crystals are deposited on the anode and are stripped therefrom to be carried along with the water, which cause crystallization thereon of carbonates contained in the water. Thereby formation of boiler scale, when the water is heated, is reduced. The water from the treatment chamber is exposed to another electric field in an aftertreatment chamber for a dwell time longer than the dwell time in the treatment chamber. Thereby, the growth of the seed crystals is enhanced. The efficiency of a treatment chamber with aftertreatment is higher than the efficiency of the treatment chamber alone.

Abstract: The activation and deactivation of an outdoors, hose faucet-mounted valve unit to control the flow of water through a standard garden hose with attached sprinkler is remotely controlled from indoors rather than at the valve unit. This is accomplished without the use of unwieldy and unsightly electrical cables by means of radio frequency (RF) signals. A remote, programmable, controller unit located indoors with attached transmitting unit commands such transmitting unit to send signals in accordance with preprogrammed instructions in the controller unit. A receiver unit attached to the valve unit intercepts the transmitted signals and instructs the valve unit to open or close the water valve and flow of water based thereon. Direct connection of the controller to the valve unit is possible such that the transmitter unit and receiver unit are not used such as during pleasant weather conditions.

Abstract: An inflatable recreational device forms a climbing structure upon which users can climb and play. The device may take the form of a representation of a mountain having bulges and indentations which serve as hand and foot holds and various handles which also act as hand and foot holds. Users can climb up and down on the device or after climbing up can slide or jump down from the device. The device can be used in water or on a surface such as the ground. The device is a generally hollow container, bag, or bladder which is inflated. Straps are secured inside the device to extend at various angles between the base, sides, and top to shape and contour the device and change the natural rounded balloon shape the device would normally take upon inflation without the various interior straps.

Abstract: A device for dispensing and carrying tape having a C-shaped handle where both ends have openings. Two cylinders inserted through each of the openings form a spindle by which to dispense and carry tape. Each cylinder has a J-slot cut into its side to receive an engaging screw which attaches through the C-shaped handle. By turning each cylinder one way, the cylinders form a spindle by which to hold a roll of warning (or caution) tape. By turning the cylinder each the other way, the cylinders retract to allow installation of a new warning tape roll.

Abstract: The invention relates to device serving as an orientation aid for blind and visually disabled, comprising at least one contactless distance measurement system (1,2) which provides correcting variables depending on the distance between the device and an object detected by the distance measurement system (1,2). At least one indicating device is also provided, which is impinged upon by the correcting variable of the distance measurement system (1,2) and which supplies an indication depending on the correcting variable. The indicating device comprises at least one tactile indicator (3) which is continuously or quasi-continuously displaced along a tactile path as monotone function of the distance measured by the distance measurement system (1,2). The tactile indicator can, for instance, comprise an adjustable element (3). The user can thus feel the distance measured by touching the position of the displaceable element (3).

Abstract: An emergency response system for detecting, locating, and responding to a predetermined medical emergency, such as sudden cardiac arrest/sudden cardiac death, in a person being sensed for the predetermined emergency, and wherein the medical emergency can be treated with portable medical equipment, such as an AED machine for treating cardiac arrest/sudden cardiac death, includes a reader worn by the person being sensed for reading a dysfunction indicating the existence or imminent existence of the emergency condition and a sensor for determining when an emergency condition is read and producing an alarm signal. A processor activates a personal alarm at the location of the person suffering the emergency, now the victim, which indicates the emergency and the victim's location to those in the victim's immediate area.

Abstract: The invention relates to a window for use in a supersonic or hypersonic target-tracking missile, the window being transparent to electromagnetic radiation. The window consist of several window layers which support each other and which are commonly supported, wherein the materials, the thickness and the arrangement of said window layers are selected to reduce mechanical stresses due to temperature during supersonic or hypersonic flight as compared to a continuously homogeneous window. In one embodiment the window layers are fixedly interconnected with their surfaces facing each other and consist of materials having different thermal coefficients of dilatation such that, with the temperature gradient occurring in said window during supersonic or hypersonic flight, substantially identical thermal dilatations are achieved in each of said window layers.

Abstract: A fin protector for a wind surfing board or similar item includes two sides secured together to form a pocket or receiving opening for the tip of a fin to be protected. Anti-scratch standoffs or spacers extend from the sides into the fin receiving opening to space the sides from the fin as the tip of the fin is inserted. The fin is inserted into the pocket far enough to flex the sides apart enough so that the sides, through the spaces, press against the fin and hold the protector on the fin. The standoffs or spacers may take the form of hooks of hook and loop fastening material with pieces of the hook material secured to the sides of the fin receiving opening so the hooks extend into the opening, or may take the form of ridges extending from the sides of the fin receiving opening into the opening.

Abstract: In a device for the passive friend-or-foe discrimination of targets, in particular of airborne targets, wherein a target to be identified is observed by a video camera, the video camera is mounted for rotation about two mutually orthogonal axes and is aligned with the target by a servo or follow-up device controlled by target radiation.

Abstract: A suture holder allows a scrub nurse to “load” (i.e., retrieve a suture needle and thread onto a surgical needle driver) with one hand during a surgical operation. The suture holder is made of spring loops arranged on a supporting base to hold suture packets. Leaf springs can also be employed on a suture holder to hold and secure suture packets during surgery.
