Abstract: The disclosure is of a medical valve for handling oxygen and suction and including a suction flow path in which there is a means for throttling down the flow to a level at which there are no, possibly damaging, surges.
Abstract: A high temperature battery of one or more cells is disclosed in which each cell is made by holding an anode electrode and a cathode electrode, of different metallic substances, together through a fused flux wetted to an electrode, which fused flux is an electrolyte, to make an anode-to-cathode contact, and the anode-to-cathode contact is heated, by a heat source, to a high temperature above a threshold temperature to generate voltaic voltage, in excess of any thermoelectric voltage; such batteries with electrodes of various configurations are disclosed. The heat-activated flux and electrolyte, such as borax, may have, vegetable-growth ashes or chemical constituents of ashes, such as lithium carbonate, added to the heat-activated flux and electrolyte to catalyze or improve the current-generating capability of the battery. The preferred anode substance is aluminum, and the preferred cathode substance is copper.
Abstract: The disclosure is of a syringe including a barrel containing an injectibe fluid and a plunger for moving the fluid. The barrel is made up of two parts which are held together in the barrel during an injection and after the injection has been made, the plunger is separated into its component parts and cannot be reassembled and used again.
Abstract: The system operates with a signal transmission/reception apparatus such as a receive antenna, or a coaxial system or the like, while the antenna is receiving information signals and it operates by injecting a low power pseudo-noise digital signal into the antenna and detecting reflected energy, the magnitude of which depends on the condition of the antenna. The reflected signal is processed and compared with the original test signal to produce a digital number representing the condition of the antenna. The digital number is compared with a table of numbers in a processor to determine the condition of the antenna.

Abstract: The disclosure is of an eyeglass frame having two lens receiving portions each having an annular channel in which a circular lens may be mounted. The annular channel includes a rear wall which faces the wearer and a frant wall which faces someone who looks at the wearer of the frame. The frame includes an auxiliary wall which extends from the front wall of the channel and changes, for someone looking at the wearer of the frame, the circular appearance of a lens in the channel to another shape determined by the auxiliary wall.
Abstract: The disclosure is of a lens having a bevelled rim and a frame having a channel for receiving the lens and carrying a bevel which is complementary to the bevel of the lens. The lens also carries on its rim a plurality of wedge-like positioning members which grip the channel of the frame and essentially lock the lens in place so that it cannot rotate.
Abstract: A valve for pulmonary medical use includes first and second valve portions which are coupled together so that they can rotate with respect to each other and feed oxygen or suction to a patient. The two portions are held together by locking means made up of male and female portions which engage each other in such a way as to pull the two portions of the valve toward each other to hold them in tight coupling.
Abstract: The disclosure is of a suction catheter having a valve body including a vertical plunger in a vertical bore and two horizontal tubes, one for connection to a source of suction and one for connection to a patient. In one position of the plunger, the two tubes are aligned with a path through the plunger to provide suction to the patient. In another position of the plunger, the tube connected to the suction is led to the atmosphere whereby suction is completely removed from the patient.
Abstract: The apparatus comprises a T-shaped member adapted to be inserted into the mouth of a patient and feeding oxygen thereto. The T-shaped member is divided into front and rear portions by an apertured wall into which a catheter assembly is to be inserted for insertion into a patient. The aperture in the wall is controlled by a rotary rod or valve having a through-hole which can be aligned with the aperture in the wall in one position and which is out of alignment with the wall in another position.
Abstract: The disclosure is of an eyeglass frame having two lens receiving portions removably coupled to a coupling member which permits the spacing between the two lens receiving portions to be adjusted. The lens receiving portions have markings and notches to permit the proper placement of a lens therein and these portions are selectively prepared to present a non-circular appearance even though they receive circular lenses.
Abstract: The disclosure is of a system and method of detecting or identifying a received TV program by forming a database of identifying digital bits for a plurality of programs, processing a TV program by modulating the luminance of pairs of lines of the program and reconstituting the program with said modulated line pairs and the other components of a TV program signal. The reconstituted program is transmitted to a location at which it is decoded to recover the digital identifying bits and comparing such bits with bits in the database to identify the transmitted program.

Abstract: Apparatus for injecting a substance into the skin including vibrating means and a hollow needle coupled thereto and receiving an injectable substance from a source thereof coupled into the open end thereof. A peristaltic pump pumps the substance to the tattoo needle. A tattooing guide is secured to the apparatus for controlling the depth of the operation.
Abstract: The disclosure is of a pulmonary catheter assembly including a tube assembly for insertion into a patient for providing oxygen and suction thereto and a flexible sleeve enclosing said tube assembly. The sleeve is secured to one end of the tube assembly and extends toward and beyond the end which is inserted into the patient. The sleeve is inflatable to permit easy introduction of the tube assembly into the patient.
Abstract: The package of the invention includes cup-shaped bottom and a cover sealed thereto, both being transparent and of a rigid material. A storage solution and a contact lens are contained within the package. The package includes means for determining the diameter of the lens therein and since it is transparent, the lens can be visually examined for defects.
Abstract: A monitor filter screen mounting device has a mounting block, a slide block slidably connected to the locating block by an adjusting screw to hold a filter screen in front of a monitor by a suspension arm, the suspension arm having one end pivoted to a cross bar on the filter screen at the top and an opposite end pivotably mounted on a round head pivot bolt and releasably retained to the slide block at a desired angular position by toothed joints. The position of the filter screen is adjusted horizontally and vertically by means of controlling the adjusting screw and the round head pivot bolt.
Abstract: The disclosure is of washing machine apparatus including a ring, within the clothes basket, and imbalance indicators coupled thereto and adapted to provide a visual indication to an operator when an imbalance occurs and provides problems in the spin cycles. The indicators show the operator where the imbalance is located and it can be easily corrected.
Abstract: A dual-purpose catheter assembly including a valve having two outlet tubes for providing oxygen and suction to a patient and a coupling manifold adapter coupled to the two outlet tubes and having a single small diameter lumen coupled to a pediatric patient.
Abstract: Fluid dispensing apparatus comprising a housing containing two box-like members, an upper and a lower with the lower box being adapted to slide into the upper box to provide a space beneath it for receiving a plastic bag containing a fluid to be fed therefrom. A drive plate is disposed within and in operative relation with the lower box and a plurality of springs disposed between the drive plate and the lower box cause the lower box to apply pressure to the plastic bag to dispense fluid therefrom.
Abstract: Apparatus comprises an analyte concentrator (one or more) for insertion into a capillary tube and containing various structures for carrying chemical substances in the flow path for attraction or repulsion of samples passed through the capillary.
