Abstract: An apparatus (FIGS. 3 to 7) for manufacturing food products such as skinless sausages comprises a tube which contains a plurality of plugs strung along a wire. The plugs are shaped to define sausage end shapes and spaced to define sausage-shaped compartments for filling with sausage-forming material. The plugs and wire are driven through the tube by a motor-driven sprocket which has peripheral recesses for reception of the plugs. Between the recesses the sprocket periphery has slots for receiving the wire. The contents of the tube are cooked by being heated and then cooled by suitable fluid jackets around the tube, or otherwise. In other embodiments, a flexible tube is pinched to form sausage compartments which are moved peristaltically (FIGS. 1 and 2) and a belt having partition-forming formations is rolled within the tube (FIGS. 8 to 11).

Abstract: A mold for stepwise molding by two or more injection shots of different materials or colors comprises fixed and movable mold halves and a slide core which combinedly form a first cavity and, with the slide core moved down, a second cavity for the shots to form a molded article of unitary structure, such as a housing section of an audio cassette tape with a see-through window. Ribs are formed on the slide core along its peripheries, and a land projection is formed on the inner side of the fixed mold half to be in contact with the molding surface of the slide core recessed with respect to the ribs. The inner peripheral wall faces of the ribs and the peripheral wall faces of the land projection of the fixed mold half are spaced apart to remain out of contact during mold clamping.

Abstract: Several conveyor rollers of singulators are made to rotate by a fruit orientation belt causing fruit carried thereon to rotate in accordance with movement of the belt such that the rotational axes of the fruit, typically lemons, orient themselves along their stem axes, or substantially perpendicularly to the direction of travel of the singulators. Downstream, the rollers contact a rotating spin-accelerating belt to substantially increase speed of rotation of the rollers and oriented fruit thereon in order to permit optical scanning devices to scan a much larger percentage of the fruit surface areas. Fruit rotate in the same direction of rotation during orientation and spin-acceleration, the latter occurring for only a very short duration.

Abstract: A high-temperature, high-shear viscometer includes a closed end tube having a chamber. A first inlet to the tube is for introducing pressurized gas therein. A second inlet to the tube is for introducing the liquid into the chamber and removing excess liquid from the chamber. A capillary tube is in communication with the chamber. An outlet for the liquid is in communication with the capillary tube. A timer is provided for measuring the efflux time of the liquid in the capillary tube. The timer is started by a device in communication with the first inlet. The timer is stopped by a device which senses the movement of the pressurized gas. The movement sensor includes a thermistor.

Abstract: A method of predicting the occurrence of deep vein thrombosis after a surgical procedure comprises monitoring changes in the internal diameter of a blood vessel using a non-invasive ultrasound technique. The frequency and magnitude of changes in vessel diameter are used to predict whether deep vein thrombosis will occur.

Abstract: A device and method for converting ocean wave energy into electricity either on moored buoys or in small vessels. The device and method of the invention utilize a U-shaped tube in communication with a gas concentration cell. The U-shaped tube resides in a cradle or other support means, secured to the buoy or other base which imparts wave energy thereto. The U-shaped tube contains a combination of liquid and hydrogen gas. The rocking of the U-shaped tube creates varying gas pressure differentials, which deposits oppositely charged particles on parallel electrocatalytic electrodes located within the gas concentration thereby creating an electrical potential therebetween, according to the Nernst equation.

Each closed loop is formed by engagement of opposite portions of the wire by a reciprocating wire transport head which brings the portions together for the twisting and cutting operations.

Abstract: A pneumatic valve mechanism, especially for controlling the movement of paper, comprises a mouthpiece (47) which defines an air intake (58), a bellows (10) coupled to the mouthpiece, a passage (42, 44) connecting the interior of the bellows to a pump so that when the bellows is not fully retracted suction is created at the air intake (58) and a seal (50) between the mouthpiece and a valve body (14) which is effective when the bellows is fully retracted, following closure of the air intake by a sheet of paper (60), to seal the air intake from the suction pump. Venting air can enter the mouthpiece in the retracted position of the bellows, to permit the sheet to drop off the intake, but without breaking the seal (50), whereby the bellows is maintained in its retracted position. The bellows (10) will only extend again to seek the next sheet when the effect created by the suction pump is interrupted, as by breaking the seal (50) by energizing a solenoid (64) and displacing a mechanical linkage (62,54).

Abstract: A symmetrical mass flow meter for placement within a defined fluid stream or pre-existing pipe line which defines an axial line. The flow meter including a single conduit tube which forms two substantially symmetrical and free floating loops between the inlet and the outlet of the flow meter. The flow meter conduit directs the fluid through the first loop and crosses the axial line substantially perpendicular to this line. The second loop directs the fluid from the crossing point and returns it into the defined fluid stream. The conduit is deflected perpendicular to the direction of flow at the crossing of the axial line along the axial line. Sensors are positioned on the periphery of each loop to measure the Coriolis reaction force created by the fluid in response to the central deflection of the conduit. The reaction forces are measured without reference to a specific axis of rotation or a fixed position.

Abstract: A read post compensator circuit for a magnetic record/reproduce device comprises a transducer for reading a sequence of magnetically coded data bits from a magnetic medium and generating an electrical signal representative of the data bits, having a sequence of peak values corresponding to the data bits and having variable time intervals between successive peak values. The circuit has a peak detector to detect the peak values of the electrical signal and a time domain filter for generating output data bits corresponding to detected peak values of the electrical signal and for dynamically varying the interval between successive output data bits in direct relation to the time interval between corresponding peak values to automatically compensate for peak shifting of the electrical signal.
