Granted: 1998-12-29
Abstract: An apparatus for dividing a continuously conveyed stream of shingled workpieces, such as bags or sacks, into leading and trailing parts has two consecutive endless belt conveyors.  The downstream second belt conveyor is driven, during a dividing operation, at a higher velocity than the first upstream conveyor in order to pull the shingled stream apart.  After the stream has been divided into the leading and trailing parts the second conveyor is driven at the same velocity as the first conveyor.  To provide separation of the stream into parts consisting of an exactly predetermined number of workpieces, an intermediate endless belt conveyor is provided, which extends parallel to the trailing portion of the second belt conveyor and during the dividing operation revolves at a lower velocity than the second belt conveyor.  The intermediate conveyor is provided with cams for arresting the leading workpiece of the trailing part of the shingled stream, against an upper pressure belt.

Abstract: A device (10) to assist manual tightening of a rope passed over a load on a vehicle, In use, the device {10) is first attached to the rope by passing the rope front the upper side of the device (10) through guide (12) to the lower side, then passing the rope up into the tower notch (15) and over the upper side of the device (10) and into the upper notch {14) so that pulling the rope downwardly will secure the device (10) to the rope. Tensioning may then be achieved by forming a loop in a portion of the free end of the rope, passing the loop around a fixed anchorage site on the vehicle and locating a portion of the loop over the pair of arms (16) and (17). The free end of rope is then passed behind and over the portion of rope extending between the pair of arms (16) and (17) and pulled downwardly, thereby urging the rope that extends be-tween the pair of tensioning arms downwardly and causing tension to be applied to the rope. The taut rope is then se-cured by tying the free end thereof to a fixed anchorage site.

Title: Dynamic signal modification for achieving interference reduction in concurrently transmitted signals
Inventor: GANS MICHAEL JAMES
IPC: H04N7/00
Filed: 1991-06-19
Granted: 1996-01-09
Abstract: Apparatus for reducing interference in a first signal caused by a second signal. Before the signals are transmitted, the first signal is tested to determine how much interference can be tolerated. During portions of the first signal which can tolerate a large amount of interference, the amplitude of the second signal is increased. During portions of the first signal that can only tolerate a small amount of interference, the amplitude of the second signal is decreased. The average amplitude of the second signal is large enough to provide an acceptable bit error rate or signal to noise ratio, yet small enough not to substantially corrupt the first signal. In one embodiment, the technique is employed to allow transmission of additional data on a television channel.

Title: Apparatus and method for a temperature compensation of a catheter tip pressure transducer
Inventor: RAYNES JOHN W
IPC: G01L9/00
Filed: 1991-10-21
Granted: 1995-11-28
Abstract: A compensation circuit for a resistance bridge corrects errors in the response of signal outputs thereof and has a voltage controlled current source across a power input and a ground reference providing a bridge excitation output cur-rent proportional to a fixed circuit reference voltage.  A buffer amplifier at the power input generates a buffer out-put voltage proportional thereto.  An instrumentation ampli-fier at the signal outputs generates an initial output pro-portional to the response therefrom.  A programmable gain amplifier at the initial output provides a compensated out-put independent of the bridge pressure response.   A gain correction part of a compensation network compensates for variations in the bridge response and an offset correction part generates an initial offset current in response to the buffer output voltage.  An offset correction amplifier gen-erates a correction signal.  The buffer output voltage and the initial offset current vary with temperature providing a temperature dependent part of the correction signal.  A reference input of the instrumentation amplifier uses the correction signal and modifies the initial output to coun-teract fixed and temperature dependent parts of offset errors in the signal outputs response.  The offset correc-tion part adjusts the fixed part independently of the temp-erature dependent part.  A single resistor adjusts positive or negative values of the fixed part.   Another resistor adjusts  positive  or  negative  slope  of  the temperature dependent part.  A method compensates the offset errors with steps of energizing the bridge and measuring the output and resistance at two temperatures and at two pressures.  The measurements are used to find correction resistances for variations  in  bridge  offset,  temperature  and  pressure response.

Title: Air treatment plant and method for balancing pressure differences in such a plant
Inventor: JAXMAR LEIF
IPC: A23L3/36
Filed: 1990-05-30
Granted: 1999-12-28
Abstract: An air treatment plant comprises a housing (1); a conveyor (4) adapted to feed food to be processed through an inlet opening (2) in the housing, to and through an air treatment area, and to feed the processed food from this area to and through an outlet opening (3) in the housing; a heat exchanger; and a circulation fan for generating a circulating air flow through the heat exchanger, the air treatment area, and the circulation fan in succession. A pressure regulating fan (25) is connected to a chamber (33) adjacent to one of the inlet and outlet openings (2, 3) for generating a pressure difference across that opening substantially equal to that across the other opening, thus minimising the air exchange between the interior and the exterior of the housing (1).     The conveyor (4) inwardly of this one opening passes a tunnel with at least two air curtain ducts which are directed substantially transversely of the conveyor path and through which some of the circulating air flows.

Title: Thermostatic control valve with fluid mixing
Inventor: KLINE KEVIN B
IPC: G05D23/13
Filed: 1992-03-04
Granted: 1999-01-19
Abstract: A thermostatic control valve assembly for use in continuously mixing a hot first fluid with a cold second fluid to continuously produce a mixed fluid at a constant temperature.  The valve assembly includes an improved mixing dome defining a mixing chamber that facilitates thorough mixing of the hot and cold fluids over a wide range of flow rates, including rates as low as two gallons per minute.  The improved mixing performance is accomplished by a plurality of baffles sequentially disposed along the flow path within the mixing chamber.  Each baffle defines an elongated opening which is angularly displaced from the elongated opening of the other baffles to turn the fluid flow, thereby optimally mixing the hot and cold fluids over a wide range of flow rates.

Title: Method for operating an asynchronous packet bus for transmission of asynchronous and isochronous information
Inventor: ROPOSH RONALD C
IPC: H04L12/56
Filed: 1992-05-15
Granted: 1998-12-29
Abstract: A facility is provided for operating an asynchronous packet transmit bus such that isochronous information packets may be transmitted from a source to a destination with a fixed, constant delay. The fixed, constant delay is achieved by employing a bandwidth management bus and assigning to port modules which contend for access to the transmit bus respective levels of priority, in which the highest level of priority is associated with isochronous information and in which lower levels of priority are associated with other types of information, such asasynchronous information.  In addition,  each port module which transmits isochronous information is assigned at least one time slot of each frame of time slots. In this way, a port module that needs to transmit isochronous information is granted access to the transmit bus during its assigned time slot if the module asserts such highest level of priority in response to its address being transmitted over the bandwidth management bus. If the module fails to assert such priority, then the time slot is marked for open contention, thereby allowing the other port modules to contend for access to the transmit bus during that time slot.
