Abstract: The device etches semiconductors with a large surface area in a trough-shaped receptacle containing a liquid electrolyte. A sample head is mounted inside the etching trough, and is provided with a device for holding at least one semiconductor wafer. The device is tilted to promote turbulent electrolyte flow in a space between a bottom surface of the semiconductor wafer and top surface of the trough-shaped receptacle.

Abstract: An adjustable striker plate assembly for a double door having a slidable member providing for adjustment of the striker plate in a horizontal direction and an adjustable member for adjusting the striker plate in a vertical direction. Two fasteners pass through the striker plate and through the slidable member and into two threaded holes in the adjustable member. A cam is rotatably coupled to the adjustable member for adjusting and holding the adjustable member in place until the fasteners are tightened.

Abstract: An interlock device for measuring the sobriety of a potential vehicle operator is coupled to the starting mechanism of the vehicle. The interlock device includes a microprocessor controlled handset and base unit. The base unit encloses relays to preclude the starting mechanism from engaging if a predetermined acceptable threshold level of blood alcohol content has been exceeded. The relays receive a signal, through the base unit microprocessor, from the handset microprocessor which has calculated the blood alcohol content of a breath sample introduced into the handset by the vehicle operator. A breath sampling housing is enclosed within the handset in axial alignment with an intake port of the handset. A water filter and valve are positioned upstream from an electrochemical fuel cell. The fuel cell is coupled to the microprocessor. A pressure transducer measures the pressure of the breath sample.

Abstract: A ramp for accessing a truck cab. A planar platform extends outwardly from the top step of the truck cab and has a straight edge that is substantially perpendicular to the axis of movement of the truck cab. A support member extends between the underside of the planar platform and the lower step of the truck cab. An inclined ramp is affixed to the straight edge of the planar platform and extends between the planar platform and the ground outwardly at an angle of less than 45 degrees from the axis of movement. The ramp and planar platform fold for easy storage outside the steps or inside the truck cab.

Abstract: A disposable device for collection of uncontaminated urine samples from small children comprising a sterile container with an inlet that eliminates direct contact between the wearers skin and the inside of the container, and which is initially closed by a delaying mechanism consisting of, e.g. a water soluble adhesive substance or material. The flow to the container is initially hindered by the delaying mechanism located in the inlet of the container. This causes the initial portion of fluid, which may be contaminated with bacteria, to be absorbed by an absorbing layer whereafter the inlet is automatically opened so that the remaining fluid can reach the container essentially uncontaminated.

Abstract: A unitary valve housing has an upper and lower portion. The upper portion has an inner chamber for accommodating two spaced apart balls and a cylindrical side skirt with oppositely positioned openings. The lower portion is cylindrical in shape and has a top shelf with adjacent circular openings for seating the two balls and openings communicating with a bottom of the lower portion. The two openings on the upper portion side skirt are aligned with oppositely positioned openings in a side of the lower housing. A secondary shelf is located in the lower housing below each of the two circular openings contiguous with the side openings. A lower end of the lower housing portion is attached to a conduit.

Abstract: A docking station is located in an offender's home. It is connected to a transformer, and a wireless modem. The docking station includes a processor board containing a microprocessor which receives the offender's home schedule from a central monitoring station via a cellular network and communicates with a miniature tracking device positioned in the docking station when the offender is at home and on the belt of an offender when he is away from home. The miniature tracking device receiving GPS signals. A tamper resistant bracelet transmitter permanently positioned on the offender's ankle communicates by wireless transmission to the tracking device.

Abstract: A power system includes power inputs, power outputs and power protection and/or power conditioning adapted between the power inputs and power outputs. In some embodiments, a graphics display is included in the system for displaying graphic images from an external video source. The power system is configurable such that the power inputs appear on the left side and outputs on the right side or the opposite with power inputs on the right side and outputs on the left.

Abstract: A one piece fabric wrap has multiple elongated pockets sewn into an inner surface. A cylindrical rope light or heat tape is positioned within the multiple pockets and hook and loop material is attached to an outer perimeter of the inside surface to provide closure of the fabric wrap around frost challenged plants. A drawstring attached along a bottom edge of the fabric wrap secures the assembled foliage wrap around the base of the plant.

Abstract: Control system for a microscope with a sensor unit, an evaluating unit and at least one drive unit, the sensor unit having at least one movement sensor, is fixed to the microscope and is aligned with the head of the microscope of the user for detecting head movements of the latter. The evaluating unit is constructed for calculating the data received by the sensor unit and for transmitting a control signal to the at least one drive unit, and the at least one drive unit is constructed for driving means set up for adjusting at least one physical characteristic of the microscope.

Abstract: A plug for sealing high pressure tubes is made from a memory-shape alloy. The plug is formed having a diameter greater than the inner diameter of the tube and is shaped by cooling to its martensite finish temperature and bending its wings in opposing directions such that at a later time, it will fit within the tube. After insertion into the tube, the plug is heated to its austenite finish temperature, restoring its wings to almost their original shape, thereby exerting force onto the tube walls, sealing the tube from leakage.

Abstract: A gel formulation is combined with a fungicidal concentrate which is a liquid mixture of about 1.2 to 16 ml parts by volume of ultra pure water having an electrical resistance of 16–26 megohms, total dissolved solids of less than 0.04 parts per million and a specific conductance of less than 0.10 mho with about 1.2 to 16 parts by volume of Willard Water as prepared in accordance with U.S. Pat. No. 3,893,943, together with one liter of a gel formulation ingredient containing 10% by weight urea, based on the weight of the gel formulation. The fungicidal liquid concentrate is applied directly to a fungal nail to soften the fungal nail and control the growth of fungi.
