Abstract: ABSTRACT OF THE DISCLOSURE       A method and apparatus for monitoring parameters which control the quality of welds made by the rotating arc method.          Total energy delivered to the work is controlled and its analog divided by the time during which energy was applied to obtain average rate of energy delivered.  Total mechanical work done on parts being welded and relative displacement of machine platens is measured and work analog is divided electronically by the displacement analog to determine average work per unit of displacement.  The two averages thus obtained are, compared to preset levels of average electrical energy and mechanical work which have been established empirically.  Indicators warn the operator of any variation from the norm.  Separate indi-cations and comparisons are also made of each of the parameters.

Abstract: ABSTRACT OF DISCLOSURE           Alternating current track circuit apparatus is provided for obtaining optimum shunting sensitivity throughout a stretch of track divided by insulated joints into adjoining double rail track circuits and having impedance bonds at respective transmitting and receiving ends.  An alternating current track feed is connected to the track rails at the trans-mitting end of each of the track circuits through a circuit tuned to resonance by a capacitor connected in series with a winding of the impedance bond at that end for energization of the associated track circuit from a source of alternating current. An alternating current receiver is provided for connection to the track rails at the receiving end of each of the track circuits through a circuit tuned to resonance by a capacitor in series with a winding of another of the impedance bonds and a track winding of a receiving relay for sensing the presence of a vehicle in the associated track section.  The receiver comprises a local source of energy derived from the same source as the transmitting apparatus and connected to a local winding of the relay in series with a variable capacitor for adjusting of the phase difference between energization of the track and local windings for providing optimum sensitivity of the relay.

Abstract: "SLUDGE SCRAPER MECHANISM"     ABSTRACT OF THE DISCLOSURE          An improved scraper to scrape the sludge from the bottom of a clarifying tank in a biological waste treatment plant.          The scraper is Y-shaped, having two angularly spaced blades which move under the sludge at such an angle as to lift the sludge onto the blade such that the sludge urges the scraper in wiping relation with the bottom of the tank.  The scraper is suspended by flexible cables from support arms which extend outwardly from an oscillating bridge moveable over the top of the clarifier tank.  The arms are arranged to extend over transverse partitions in the clarifier tank drawing the flexible cables over support rollers as the bridge approaches the partition to lift the scraper upwardly as the scraper approaches the partition to pre-vent sludge from being trapped against the partition.

Abstract: A B S T R A C T      An improved circuit for protecting the motor of a refrigerant compressor includes first and second magnetic contactors which are connected between a source of three-phase AC voltage and the compressor motor.  The contactors are normally operated simultaneously so that each of the contactors is periodically opened and closed in accordance with the demands for operation of the compressor motor.  If one of the contactors falls in the closed position, the other contactor will open to protect the compressor motor.  This result is accomplished through use of a high impedance relay coil provided in parallel with contactor switches in the common line to the compressor motor and a normally closed switch actuated thereby in the control circuit, whereby if one of the contactors should stick closed, the high impedance relay coil can be energized to open the normally closed switch and prevent compressor motor operation and possible damage to the compressor motor.

Title: Primary alkaline cell having a stable divalent silver oxide depolarizer mix

Abstract: ABSTRACT OF THE DISCLOSURE            A primary alkaline cell having a stable divalent silver oxide depolarizer mix comprising a negative electrode (anode), a divalent silver oxide (AgO) depolarizer mix, a separator between said negative electrode and depolarizer mix, and an alkaline electrolyte.  The surface of the depolarizer mix is treated with a mild reducing solution to form a reduced layer surroun-ding the mix, and the surface of the reduced layer adjacent to the separator is coated with a layer of silver.  The reduced layer surrounding the depola-rizer mix in combination with the layer of silver provides improved stability of the depolarizer mix in the alkaline electrolyte and a single voltage pla-teau during discharge of the cell.  The primary alkaline cell is characterized by a maximum open circuit voltage of about 1.75 volts. The silver layer on the surface of the reduced layer surrounding the depolarizer mix can be formed by treating the reduced layer with a strong reducing solution to form a subs-tantially continuous and electrolyte permeable silver layer, or alternatively, the silver layer may be formed by placing a silver screen, expanded silver metal, perforated silver foil or porous silver powder layer on top of the reduced layer surrounding the depolarizer mix and adjacent to the separator. It is preferred that the layer of silver be substantially continuous and electrolyte permeable which may be accomplished by treating the reduced layer surrounding the mix with a strong reducing solution.  When forming the layer of silver by treating the reduced layer with a strong reducing solution, it is preferred that the depolarizer mix surrounded by the reduced layer be con-solidated in a cathode container prior to treating it with the strong reducing solution.  The depolarizer mix may contain from about 50% by weight to about 100% by weight of divalent silver oxide based on the total silver oxide con-tent and still provide a cell with a single voltage plateau discharge.

Abstract: ABSTRACT OF THE DISCLOSURE          The specification discloses a burglar alarm system which is capable of detecting changes of load on a certain sector of terrain.  The system employs a sensor consisting of a flexible mat containing tubular, intercommunicating and inflatable channels bridged by a supportive, elastic plate over the entire extent of the mat.  The channels contain a liquid or gas and any change in volume or pressure in the channels is sensed by a detector and the alarm is operated.          In this way it is possible to provide a large-area sensor in which any load on the elastic plate is transmitted to the channels even when the mat is buried in soil which subsequently freezes.

Abstract: ABSTRACT OF THE DISCLOSURE Machines are provided for loading fish in boxes.  The novel machinery has a first conveyor supporting a series of transport containers and serving to transfer fish sideways while each is disposed in its respec-tive transport container in a preselected position with the heads of fish in adjacent containers facing in opposite directions and the bellies thereof directed upwards.  Cooperation feed means are provided for supplying fish to the transport containers of the first conveyor, and a second conveyor is pro-vided for receiving fish from the first conveyor, the second conveyor having a series of catch devices, each such catch device being adapted to engage its respective fish and to effect transfer thereof to an associated box for deposition therein.  The two conveyors are arranged to be driven at a uniform speed in a continuous circulatory movement.  The relative disposition of the conveyors is such that local regions of the paths of movement of the catch devices and the transport containers coincide, thus enabling the catch de-vices to engage their respective fish in the transport containers one after the other.  The fish are retained on the second conveyor in groups between corresponding groups of catch devices by means of cooperating, co-travelling check elements within a preselected region of the path of movement of the second conveyor between a first position in which the fish are lightly clamped together between the catch devices and a second position in which a group of fish can be transferred to its associated box.  By this machine it is possible to increase the capacity per minute by a factor of four, without reducing the quality of the raw material or of the finished product.
