Abstract: A modular telemetry cable system having first and second array terminals spaced apart a distance of D. A cable extends between the terminals having X number of analog signal transmission means which is connected to 2X transducer sets for gathering 2X analog signals. The analog signals are processed and transmitted as digital signals over a digital transmission means connected between the terminals. At the location in the cable of the two interior transducer sets, the cable is penetrated to connect the interior transducer sets to the same analog transmission means. The portion of the same analog transmissions means between the two interior sets is disconnected from the two interior sets. At the penetrations in the cable of the two interior sets, the other analog transmission means are cut. One transducer set on opposite sides of the cuts in the other transmission means are connected to each of the other analog transmission means.

The matrix resulting is subsequently contacted by biotin labeled monoclonal IgM antibody and labeled avidin.

Abstract: A relay adapted to be mounted on a printed circuit board, and a method for mounting such relays. The relay includes the usual terminals (23, 24, 26 27, 28, 29) extending therefrom and adapted to be mounted on a printed circuit board (30) and electrically coupled to conducting paths on the board. In addition, however, the relay is provided with additional load terminals (56, 59, 62, 82, 92) which function as external connection junctions to connect the relay directly to the load being controlled via a circuit that completely bypasses the printed circuit board. According to a preferred embodiment, the relay includes stationary contact members formed to have not only board-mounted terminal portions extending therefrom but also external terminal portions for direct attachment to the load.

Abstract: A jig for use in stitching together two layers of material on a stitching line defining a corner. The jig has a lower plate (1) having a slot (4) through which stitching may be effected, the slot including at least one corner. An upper plate cooperates with the lower plate and a fulling plate (3) is positioned between the lower and upper plates and has fulling means (6 to 8) on its upper surface for defining pleats in a fabric layer placed over the fulling means. At least one of the fulling means has an upstanding, pleat-forming member (11) which is positioned so that the pleat formed thereby extends towards the slot (4) at a line that intersects the slot at a location lying ahead of the associated corner (13).

Abstract: The invention is a method and apparatus for substantially eliminating from a seismic signal channel an interfering hiline signal in a differential mode. Differential mode and common mode components of the interfering signal are coupled from the seismic signal channel, and are correlated with each other to obtain a correlation signal. The correlation signal and the common mode signal are multiplied to obtain a correction signal that is applied to the seismic signal channel to substantially eliminate the differential mode component of the hiline interference signal. The correlation between the differential mode and common mode signals is accomplished with both in-phase and quadrature phase components of one of them so that two correlation signals actually are produced.

Abstract: Dough is dispensed from the bottom of a dough hopper with a screw conveyor that slices into the dough mass and moves the dough horizontally out of a lower opening in the hopper and through a discharge conduit and discharge nozzle. The screw conveyor divides the conveyed dough into batches and the dough is worked in the discharge conduit and air from about the batches of dough is vented from the discharge conduit prior to extruding the dough through the discharge nozzle.

Abstract: A molecular separation column for effecting the differential distribution, between two phases, of the components of a sample flowing therethrough. The column contains a substantially homogenous solid stationary phase which comprises a porous matrix of fiber having particulate immobilized therein, wherein at least one of said fiber or particulate is effective for molecular separation. The column is characterized by a reduced pressure drop, increased axial dispersion, more uniform peak shapes and better separations at high sample loading.

Abstract: An apparatus is provided for the continuous measurement of the bulk density of particulate material comprising an endless belt weighing conveyor having a compression zone and a weigh span downstream of the compression zone, means for feeding the material to said compression zone, a compression unit at said compression zone having a series of rollers an axes extending transverse to the direction of movement of the weighing conveyor, and transducer means provided at the weigh span for producing signals proportional to material weight. The rollers may be driven with a surface speed equal to the weighing conveyor belt speed and additional rollers may be mounted below the weighing conveyor to carry the load. The rollers are preferably embraced by a belt which gives a continuous surface and prevents tobacco getting between the rollers. In which case, the belt is driven with the same speed as the weighing conveyor belt, via a terminal roller and the other rollers follow.

Abstract: A self supporting fibrous matrix containing immobilized therein at least about 5% by weight of micro-particulate, with an average diameter less than 1 micron, preferably fumed silica, or alumina, and flocculating amounts of an organic polycationic resin and an organic polyanionic resin, is useful for fluid treatment and filtration processes, especially delipidization and depyrogenation of fluids such as serum.

A specific gear and linkage drive system is provided, including interengaged gears driving the compressing shoes via links on either side of the shoes.

Abstract: A chromatography column for effecting chromatographic separation of at least two components of a sample flowing through the column. The column comprises a housing and at least one solid stationary phase within the housing. The stationary phase has chromatographic functionality and is effective for chromatographic separation. Means are provided for radially distributing the sample through the stationary phase and for collecting the sample after the sample has flowed through the stationary phase. The stationary phase comprises:(a) a swellable fibrous matrix in sheet form having chromatographic functionality and being effective for chromatographic separation, spirally wound around the longitudinal axis of the solid stationary phase to form a plurality of layers around the axis; and(b) a spacer means between each layer for permitting controlled swelling thereof and enhancing the distribution of sample flowing radially through the stationary phase.

Abstract: A timing mechanism for use in an appliance such as a domestic clothes dryer, for example. The mechanism includes a synchronous motor and two output shafts. One output shaft is the conventional rotary output shaft of the speed reducing gear train associated with the synchronous motor. The second output shaft is the rotary axle of a Geneva follower gear that is driven by a Geneva driver gear that is in turn driven by a gear located intermediate the input and first output shaft of the gear train. The intermittent rotation of the second output shaft, wherein each intermittent rotation is accomplished in a relatively rapid time, permits a timing cam thereon to control a switch actuator to provide a precise and quite brief switching action of the order of five seconds, for example.

Abstract: An instrument including a gyroscopic rotor mounted to precess about a predetermined axis in response to pivotal movement of the rotor about a sensing axis, with the rate of precession being measured and being utilized to determine the amount of said pivotal movement above the sensing axis. Two or more such rotors precessing about different axes can respond to different components of the earth's rotational movement, or to other component movements or torques. Differences in the rates of precession of the two rotors indicate the relative strengths of the corresponding components of the earth's movement, and afford a basis for deriving an indication of azimuth.
