Abstract: A hospital garment comprises finished slits with fasteners which extend the entire length from the collar down the entire length of the sleeve to the wrist portion of the gown. This structure allows the placement and removal of intravenous apparatus as well as surgery or applying or changing bandages without the necessity of removing the gown or cutting it apart. A similar garment is provided for the lower portion of a patient's body.
Abstract: An automatic transmission comprises a first rotating assembly coupled via a bias member to a second rotating assembly. The second rotating assembly varies its effective diameter in response to the torque applied to the transmission. The bias member, e.g., a spring, holds the first and second rotating assemblies in a first relative position. However, as the applied torque increases the bias tension is overcome and relative rotation of the first and second assemblies occurs towards a second relative position; and simultaneously, the effective diameter of the second rotating assembly decreases.
Abstract: A border molding strip is placed about the perimeter of an existing window pane. A second pane is then placed upon this border material. A retaining border is then placed to retain the window pane firmly against the border material, thus creating an airtight seal between the existing window pane, the border material and the second window pane. Appropriate adhesive and sealing compounds are applied to insure an airtight seal. Thereafter, the space between the existing window pane and the supplemental pane is purged with dry gas and may be evacuated through an opening exposed under a portion of the retaining means. After the window pane is purged and evacuated, a plug is inserted and the opening in the molding material is closed.
Abstract: A one-piece light metal alloy snowshoe is coupled to a boot attached to a crampon/binding assembly via a fixed pivot assembly. A quick lock-release device of the crampon/binding assembly may be adjusted to accommodate any size boot. Thereafter, the simple moving of a locking-release lever will firmly attach and release the boot to the crampon assembly and the snowshoe.
Abstract: A hand held logic probe serially clocks applied data bits into a shift register in response to a user actuated thumb switch. The shift register is coupled to a hexidecimal/octal converter which drives a digital display. The display is reset in response to the user actuating the thumb switch for more than a predetermined time period.
Abstract: A drop-on demand ink jet printer and a method of ink jet printing are disclosed which produce drops whose diameter have a ratio to the internal diameter of their print nozzles of 1:2 instead of the standard ratio of 2:1. This change in the basic ratio of drop diameter to print nozzle diameter is a result of the motion imparted to the print liquid by the actuation of the print nozzle. The print nozzle is cocked, released, and abruptly stopped to impart forward momentum to the print liquid near the orifice of the print nozzle. This momentum urges the liquid to be expelled from the print nozzle. Cutting the orifice of the print nozzle at an oblique angle to the run of the print nozzle creates a leading edge on the print nozzle which increases control of drop placement. The leading edge encourages formation of a single umbilicus of expelled print liquid from which a drop will be severed.

Abstract: A holder is provided which contains at least two different flossing materials. The one material is typically unwaxed dental floss. The other material varies in thickness and is selected so as to provide, when doubled over, the appropriate thickness to be presented between the interdental spaces to accomplish the proper cleansing of the interdental area. Various multi-stranded materials are provided for selection to be placed in the holder. Multi-stranded cotton embroidery thread may be used. The one material which is fairly thin and is unwaxed or waxed dental floss or even waxed tape is used so that it can be worked between the contacts of the teeth. The multi-stranded material will be used for the primary cleaning. The placement of the cleaning material between the interdental area is accomplished as follows: A loop of the thin material is interlocked with a loop of the thicker material.
Abstract: Apparatus for attaching to a snow ski includes a retractable member for extending beyond the edge of the ski to provide a semi-circular engaging surface that a ski pole can be butted up against. The apparatus allows a skier to easily maintain his position on a slope or secure the position of one ski while moving the other forward to a new position. The apparatus is also balanced along the longitudinal axis of the ski so that when the member is retracted the skis are balanced along the longitudinal axis.
Abstract: A surgical knife assembly in which the handle portion tapers down and is truncated obliquely at a selected angle to form a blade guard surface. The blade of this knife has a dull edge and a sharpened edge which meet in a point with an acute included angle. This blade is affixed to the blade guard surface so that the dull edge of the blade intersects the straight edge of the blade guard surface with the side portions of the blade being perpendicular to that same straight edge. In addition, when the blade is affixed to the blade guard surface, the dull edge of the blade is mounted so that it is substantially parallel to the major axis of the handle. To insert the blade in the surface where the incision is to be made, the knife is designed so that the user will hold the surgical knife so that the guard surface is substantially parallel to the surface to be cut.
Abstract: A power supply includes an inverter circuit comprising silicon controlled rectifiers which are driven by a variable frequency control signal. The frequency of the control signal is determined by monitoring the power output requirements of the power supply. Because of the continuous sinusoidal operation of the inverter, the supply generates a very low level of radio frequency interference (rfi).
Abstract: Two planar bodies of reflective material are coupled together, one before the other, and in line with the line of vision from an intended observation point. The base reflective body is designed to be attached to an object, vehicle, or the like. The second reflective body is movably coupled to the base reflective body. Movement of the base reflective body induces relative movement of the two reflective bodies. A counter weight is attached to the second reflective body to increase this relative movement. Enhanced visibility is provided not only by the relative movement of the two reflective bodies, but also by dynamic prismatic action, i.e. the reflection by the base reflector of light transmitted through the top reflective body.
Abstract: An opening is provided in a pantyhose garment in which the panty portion comprises a double knit fabric material which by its construction presents overlapping flaps which by digital manipulation expose the opening through which urination can be accomplished without any removal or partial removal of the pantyhose garment.
Abstract: A fault tolerant multiplier which utilizes a plurality of full adder rows has the ability to permanently deselect a row when a fault is detected in its initial testing. An extra row is provided to allow this deselection and transfer gates are provided between each row to shift the sum and carry logic on to the next row at the point of the deselected row and all rows therebeyond.
Abstract: A special bathtub for invalids has a fixed end part which abuts an oblong rotatable end part operable by control of the pressure of the water source. The center of curvature of the abutting faces of the fixed end part and the oblong rotatable end part is offset from the pivotal axis of the rotatable end part to incorporate a wedging feature in effecting a watertight seal. An interlocking latch and water sensor prevent inadvertent opening of the tub when it is filled with water.
Abstract: Two input signals of uncertain phase relationship are applied to trigger circuits which develop sharply defined logic level transitions in response to the input signals crossing predetermined amplitude threshold levels. These logic level transitions are then used to clock a register whose outputs are gated and filtered to provide a DC output signal whose level indicates the phase difference between the two input signals.
Abstract: Steel strand is passed through a plurality of upper and lower multi-part chucks which each are capable of grasping and holding steel strand passed through it when they are seated in upper and lower seating chambers, respectively. Upper and lower hydraulic seating rams comprise pistons used to cause chuck seating plates to be driven against the top flanges of the upper and lower chucks, thereby causing them to seat within their respective seating chambers. Either or both the top and bottom chucks may be seated at the same time. A hydraulic system allows an operator to smoothly lift and lower loads through the seating and unseating of the upper and lower chucks and the extending and retracting of pistons of main lifting rams interposed between plates containing the upper and lower chuck seating chambers.
Abstract: This patent applies to a kennel which incorporates a number of wedge-shaped partially covered enclosures, annularly disposed in an outer ring and inner ring separated by covered corridors.It incorporates a series of gutters for waste removal which resists the spread of disease by means of an overhanging splash-inhibiting lip. It includes a number of compartment walls, each extending beyond the run and over the top to prevent animals from sniffing each other or coming in contact with each other, thereby inhibiting the spread of airborne and body waste diseases. A carefully designed airflow system, compatible with radiant floor heating, resists cross-contamination of animals from inadvertent intermixing of air; vents and ultraviolet lamp exposure assures purging and purification of compartment air.
