Title: Transducer for converting linear energy to rotational energy
Inventor: SIMONDS EDWARD L
IPC: F01B9/08
Filed: 1995-10-10
Abstract: A transducer includes a linear input power source (12) connected to a connecting rod (24) in turn connected to output drive shafts (30 & 36) through one-way clutches (28 & 40), with the output drive shafts being interconnected through gears (32 & 40) such that when one shaft is powered, the other is coasting. The power source includes multiple stern powered cylinders (16 &  94). Inlet and outlet valves (44) for each cylinder chamber are controlled by an actuator (56) which instantaneously snaps the valves between open and closed positions. The power cylinders (16 & 94) may be operated individually, in parallel or in series and as required, a valve passageway through the piston (18) may be operated to equalize pressure. A pair of O-rings (121) on the piston (18) engage the cylinder wall only when the adjacent chamber is pressurized, thereby reducing drag in operation of the piston.

Title: Ostomy pouch with intervening membrane and superabsorbent
Inventor: OBERHOLTZER GARY E
IPC: A61F5/441
Filed: 1997-04-17
Abstract: The pouch is formed of first and second thin barrier film walls welded along the periphery to form a waste receptical. One wall has an inlet defined by an attachment ring. The ring mounts the pouch on an adhesive faceplate adapted to adhere to the skin surrounding the stoma. A membrane, formed of material which is gas permeable but transmits little moisture and no liquid, is situated between the walls to separate the receptical into an inlet chamber, where solids, liquid and most moisture are retained, and an outlet chamber into which gas and a small amount of vapor passes. A filter is provided to permit the gas to exit the outlet chamber.      A first section of superabsorbent material isolates the filter from the outlet chamber. By absorbing any moisture in the gas before it contacts the filter, blockage of the filter is prevented. A second section of superabsorbant material is provided near the bottom of the output chamber to absorb moisture which otherwise may cause the membrane to stick to the pouch wall, resulting in a substantial reduction of the gas transmissibility of the membrane.

Title: Method and means of linking sausage
Inventor: DAMSTETTER ROBERT W
IPC: A22C11/10
Filed: 1995-08-14
Abstract: A machine (10) for linking sausage has a pump (22), a stuffing tube (26), a casing on the stuffing tube, and a pair of linking chains (32) downstream from the outlet end of the stuffing tube (26). A scale (40) is located downstream of the discharge end of the stuffing tube (26) and is operatively connected to the pump (22) to increase or decrease the output speed of the pump (22) as the weight of the encasing product decreases or increases, respectively from a predetermined target weight. The linking chains (32) have spaced-apart linking elements. A proximity sensor (46) monitors the linking chains (32) as they are rotating and senses variations in the distance between the linking elements as compared to a predetermined distance to determine stretching of the chains. A  mass flow sensor (44) is located on the machine (10) adjacent the outlet of the pump to measure the mass of meat emulsion exiting the pump (22). The mass flow sensors (44) are operatively connected to the pump (22) to increase or decrease the output of the pump (22) as the mass thereof decreases or increases, respectively from a predetermined target mass. The method of linking sausage comprises the mass flow sensing of the output of the pump (22) and the regulation of the pump speed thereby. The method further employs the use of a proximity sensor (46) to monitor the linking chains (32) to determine the stretching thereof. The method further includes the step of weighing the encased product and increasing or decreasing the output speed of the pump (22) as the weight of the product decreases or increases, respectively with respect to a predetermined target weight.

Patent CA-2206255-A1 (CA)
Inventor: BACON FORREST C
IPC: B65B9/093
Filed: 1995-11-02
Abstract: A continuous vertical form-fill-seal packaging machine is disclosed, along with a related method, utilizing a synchronized product clamp (31, 32) for staging/settling each product batch. The film feeding, carriage driving, sealing jaw movement, as well as the clamp operation, are computer controlled.  In the continuous film/tube feed mode, the sealing jaws (25, 26) move in a modified sine wave motion with the film; the clamp for staging the product batches moving in a similar manner, but 180 degrees out-of-phase. Each product batch is released by the clamp adjacent to the sealing jaws so that the drop to the blousing plates and eventually into the bag being formed is minimized.  The clamp is vibrated to further enhance the coalescing and settling function.

Patent CA-2224056-A1 (CA)
Title: Interferometric switch
Inventor: NOLAN DANIEL A
IPC: G02B6/26
Filed: 1997-06-09
Abstract: A compact monolithic interferometric switch as a Mach-Zehnder switch is formed such that one of the waveguide paths (47) between the input and output couplers contains a material which exhibits a resonant nonlinearity, whereby its refractive index changes when pump power propagates through it. Each of the waveguide paths (47, 46) has a different propagation constant whereby signal light is subject to a different delay in each path when no pump power is propagating through the rare nonlinear path. An input signal applied to the input of the switch appears at a first output terminal when the pump power does not propagate through the nonlinear path, it appears at a second output terminal when the pump power is applied to the nonlinear path. Switching occurs at relatively low levels of pump power.

Filed: 1998-02-18
Abstract: The invention is a method and apparatus for controlling the vibration modes of a vibratory rotation sensor (VRS) comprising a resonator and a housing which toget her serve as the ground potential reference. The resonator has a surface with a conductive region and the housing has a plurality of attached electrodes positioned opposing the condu ctive region on the resonator. The parameters of the resonator standing-wave vibration patter n are determined by feeding an ac sensing signal to the conducting region on the reson ator and obtaining one or more vibration signals while the electric potential of the cond uctive region on the resonator is maintained within 100 millivolts of ground. Each vibration s ignal is a replica of the ac sensing signal with amplitude modulation which is a periodic f unction of the distance from a point in the conducting region of the surface of the resonator t o an opposing housing electrode. The frequency of the amplitude modulation is the vibration fr equency of the resonator. The parameters of the standing wave are determined from the vibra tion signals, and these parameters are used in controlling the standing-wave paramete rs by generating appropriate ac forcing voltages which are applied to the housing elec trodes. 21
