Abstract: To monitor stereo audio signals associated with a TV video signal, the two stereo audio channels are converted to digital form (20, 21), a memory (22) has bits written into it at addresses formed by successive pairs of such values in digital form to form a map therein of a Lissajou figure representing the relationship between the two channels, the memory is read out linearly in synchronism with the operation of the monitor, and the output inserted into the TV video signal (VID) being displayed. The memory may be read out diagonally, so as to produce a diamond display, by a line counter (LB, RB) and a bit counter (LL, RL) for each channel, the line counters being loaded with predetermined counts at the beginning of each field and counting lines and the bit counters being loaded from the line counters at the beginning of each line and counting bits along the lines, three of the counters (LL, RL, RB) counting in one direction and the fourth (RL) in the other.

Abstract: A coaxial audio cable is provided having a core, braided inner and outer conductors, dielectric layer between the inner and outer conductor and a jacket surrounding the outer conductor. The inner conductor is disposed around the core at a braid angle of approximately eighteen degrees. The dielectric layer is wrapped around the braided inner conductor. The outer conductor is disposed around the dielectric layer at a braid angle of approximately thirty-eight degrees. The cable is designed to provide a 5:6 overall ratio between the number of strands in the inner conductor and the number of strands in the outer conductor. The inner and outer conductors of the coaxial audio cable are designed to have matching series impedances.

Abstract: An indicator device which can be attached to a standard oxygen flow meter is disclosed. The indicator device has a rod along which a pointer can be moved and locked into position. The pointer can be set at the oxygen flow level prescribed by the physician as indicated by the scale on the oxygen flow meter. If the oxygen flow level is changed or if oxygen is discontinued for any period of time, the attendant can then set the oxygen flow to the prescribed level by controlling the valve on the oxygen flow meter so that the float, which indicates oxygen flowing liters per minute is positioned opposite the position of the pointer. This prevents erroneous or improper setting of oxygen flow levels to patients after interruption or change of oxygen flow level, which can be dangerous and life threatening.

Abstract: Apparatus for dispensing includes a cartridge holder and main body having a generally circular central portion with three perpendicular flanges extending from one side and an elongate portion extending from the other side. A drive means on the elongate portion mounts a U-shaped drive rod for axial movement. Each flange includes a slot for receiving a pin formed on a replaceable generally cylindrical cartridge to act as a bayonet fitting. Viscous material is expelled from the held cartridge by driving the rod axially. A nozzle attachment has a primary section connected to the exit of the cartridge and includes a secondary section for holding a replaceable hardener tube, with the hardener being expelled by axial movement of a portion of the rod. The nozzle attachment includes a planar end surface for simple cleaning.

Abstract: A flash-type analog-to-digital converter (ADC) uses only 2.sup.n-m comparators coupled to the analog input line to generate a n-bit digital output signal. Each pair of these actual comparators are coupled, in parallel, to 2.sup.m pseudocomparators which provide values representing comparisons of the input signal value to respective reference values between the reference values used by the actual comparators. The output signals of each pair of actual comparators are combined in respectively different proportions at each of the pseudocomparators. In this manner, the output signals of the actual comparators are averaged to produce the interstitial comparison values. In one embodiment of the invention, the ADC is implemented in BiCMOS technology with a bipolar differential input stage and a CMOS latching comparator. Signals are distributed from the actual comparators to the pseudocomparators via a pair of resistive ladder networks.

Abstract: A mobile vapor recovery apparatus (10) efficiently removes materials from the vadose layer of earth soil. The apparatus (10) has a plurality of intake ports (14a-14d) each configured to releasably connect to a well pipe communicating gas having vaporized materials from a well in the soil. The intake ports (14a-14d) communicate the gas to a common manifold (24). A fluid collection tank (26) receives the gas from the manifold (24) and collects fluid entrained in the gas. A blower (32) draws the gas into the intake ports (14a-14d) by forcing the gas from the tank (26) and out of an exhaust port (34). A transportable support frame (12) is configured to support the plurality of intake ports (14a-14d), the fluid collection tank (26), and the blower (32) in a self-contained transportable unit. In addition, the mobile vapor recovery apparatus (10) may be mounted within a trailer unit (82) having a locking mechanism (102).

Abstract: This invention comprises a control interface between a machine and a physical object. The invention includes an infrared transmitter for transmitting a first infrared signal to an object. Upon striking the object, the infrared signal is reflected forming a reflected infrared signal. An infrared receiver receives the reflected signal from the object and the reflected signal is transformed into a second signal which may be either an analogue type or a yes/no threshold type, representative of a distance between the object and the receiver. The second signal is coupled to the machine. The apparatus is a cordless touch-free controller interface for use with a machine. The present invention is ideally suited for controlling cursor position for use with computers and also with video games.

Abstract: The invention provides a self-adhesive tie for a bag, the tie comprising a folded length of tie material, an adhesive layer for adhering the folded length to a bag, and a backing of release material covering the adhesive layer. The invention also provides a method of making a succession of self-adhesive ties for bags, the method comprising the steps of: (a) disposing a succession of folded lengths of tie material on a web, the web including a backing of release material and each folded length being adhered directly or indirectly to the backing of release material; and (b) cutting the folded lengths of tie material and the web to form a succession of ties for bags.

Abstract: A braking system for in-line roller skates includes a hand-held brake actuator coupled to a plurality of brake assemblies by a conduit system. The brake assemblies are mounted on a housing beneath the boot portion of the roller skate adjacent selected ones of the rollers. The conduit system supplies hydraulic fluid to the brake assemblies which apply frictional pressure to the side walls of the rollers thus stopping the skates.

Abstract: An electrostatic powder coating apparatus comprising a powder reservoir, a gas flow injection chamber, a diffusion chamber and a coating chamber and method for coating a substrate or target objects. The injection chamber receives powder from the reservoir at a controlled rate. The powder particulates are entrained by a gas flow within the injection chamber. The diffusion chamber receives the particulates from the injection chamber. The diffusion chamber deaccelerates the particulates and creates a particulate cloud. The coating chamber receives the particulate cloud. A housing encloses the coating chamber. The coating chamber is isolated from the ambient atmosphere. The coating chamber has a cloud inlet and a cloud outlet. The cloud flows through the coating chamber from the inlet to the outlet. One or more deflectors, within the chamber, define a passage and two or more pockets adjoining the substrate or target objects.
