Abstract: ABSTRACT      A method of and apparatus for extracting the meat section and juice from a fruit while minimizing the amount of undesirable flavor components, e.g. peel oil, released from the fruit's peel.  In one embodiment of the present invention, whole fruits are fed into a single station extraction apparatus that first cuts a equatorial groove in the fruit's peel while the fruit is rotated.  A semicircular coring blade is then inserted into the groove and rotated 360° which severs a spherical chunk of fruit meat from the peel.  The small amount of fruit meat remaining on the peel's inner surface is then preferably extracted with a remaining element or fluid jet nozzle.  In other particularly preferred embodiments, the grooving, coring, and reaming component mechanisms are incorporated into an indexing turret apparatus and a high-speed continuous motion turret apparatus.

Abstract: A motor control method and apparatus for a hoist is disclosed in which a drive motor is connected to an adjustable frequency power supply in which the frequency of the power supplied to the motor can be selectively varied.  At the initiation of a hoist operation, when the hoist brake is holding the motor and an object constituting a load on the motor stationary, power is supplied to the motor at a predetermined low frequency which is sufficient to provide load holding torque upon release of the brake.  The actual current level of the power supplied to the motor is sensed at the initiation of the hoist operation and a signal representative of that current level is compared with a reference signal representative of a current level which is sufficient to provide the load holding torque.  If the signal representative of the actual current level of the power supplied to the motor exceeds the reference signal, an output signal is provided which will result in the release of the hoist brake from its holding condition.

Title: Cement-type mount for a lamp including means for protecting the lamp exhaust-tube tip against fracture
Inventor: GOLZ THOMAS M
IPC: H01K1/36
Filed: 1990-05-24
Abstract: CEMENT-TYPE MOUNT FOR A LAMP INCLUDING MEANS FOR PROTECTING  THE LAMP EXHAUST TUBE TIP AGAINST FRACTURE            ABSTRACT           For mounting a lamp that comprises a glass en-velope including a seal and a glass exhaust tube having a tip projecting from the seal, there is provided a base having a cavity for receiving the seal and the exhaust-tube tip.  Within the cavity about the seal and the tip is a hard cement for fixedly positioning the envelope within the cavity.  Surrounding the tip and located be-tween the tip and the adjacent cement is a thin layer of soft material that can yield in response to forces de-veloped thereon by thermal expansion and contraction of the cement, thereby protecting the tip from being cracked by these forces.  The hard cement extends into contact with the glass seal about a substantial portion of the seal's exterior surface so that the hard cement is able to fixedly position the envelope relative to the base without interference from the softer material about the tip.

Abstract: MULTI-FUEL ENGINE CONTROL WITH       OXYGEN SENSOR SIGNAL REFERENCE CONTROL            Abstract of the Disclosure A fuel control for an engine using a liquid fuel mixture of two fuels such as gasoline and methanol acts in closed loop on a vehicle exhaust mounted oxygen sensor to maintain a stoichiometric air/fuel ratio. The closed loop portion of the control compares the oxygen sensor output voltage to a reference or reference window in the process of indicating a lean or rich mixture; and the fuel control is responsive to a fuel composition sensor to shift the reference or reference window with changing fuel composition to maintain a consistent relationship between the reference or reference window and stoichiometry as the fuel composition changes.

Title: Detection of an anticorrosion oil applied into a ship's ballast
Inventor: GAMACHE ROGER A
IPC: G01N21/91
Filed: 1991-01-21
Abstract: A method for detecting the presence of any discontinuity in an anticorrosion oil coating applied onto the internal walls of a nautical ballast. The method comprises the steps of (1) adding an oil-soluble tracer to the anticorrosion oil coating prior to its application onto the internal walls of the ballast, the tracer being insoluble in water and rust; inert to rust, water and the oil; and capable of emitting visible light under the effect of a black light; (2) after application of the oil coating, submitting the inside walls coated with the oil to the effect of a black light, and (3) checking the continuity of the visible light that is emitted by the oil coating, whereby the presence of oil is detected by visible light emitted by the tracer and its absence is detected by the absence of any emitted visible light. An anticorrosion oil containing such a tracer is also disclosed.

Title: Pneumatic gap sensor and method
Inventor: BAGDAL KARL T
IPC: B22D11/06
Filed: 1991-01-22
Abstract: ABSTRACT OF THE DISCLOSURE An  apparatus  and  method  for  monitoring  and maintaining a predetermined width in the gap between a casting nozzle and a casting wheel, wherein the gap is monitored by means of at least one pneumatic gap sensor.  The pneumatic gap sensor is mounted on the casting nozzle  in proximity to the casting surface and is connected by means of a tube to a regulator and a transducer.  The regulator provides a flow of gas through a restrictor to the pneumatic gap sensor, and the transducer translates the changes in the gas pressure caused by the proximity of the casting wheel to  the  pneumatic  gap  sensor  outlet  into  a  signal intelligible  to  a  control  device.  The  relative positions of the casting nozzle and casting wheel can thereby  be  selectively  adjusted   to   continually maintain  a  predetermined  distance  between  their adjacent surfaces.  The apparatus and method enables accurate monitoring of the actual casting gap in a simple and reliable manner resistant to the extreme temperatures    and    otherwise    hostile    casting environment.

Patent CA-2038146-A1 (CA)
Title: Pyrolytic conversion system
Inventor: BREU FRED A
IPC: C10B53/00
Filed: 1991-03-13
Abstract: PYROLYTIC CONVERSION SYSTEM                        Abstract A rotary, continuous pyrolytic conversion system converts solid hydrocarbons into gases, liquid hydrocarbons and char by pyrolyzing feed stocks including: plastic waste, tires and plastic from automobile shredding operations; containers and trays of styrofoam and other plastic materials such as used in "fast food" restaurants; rubber, leather; tires; garbage; sewage sludge; coal; oil shale; broken asphalt and the like.  These materials are preferably shredded and kinds thereof having different melting points are mixed to facilitate movement of the feed stock through the converter without clogging.  Preferably, the materials are baled and injected into the converter where they are severed as they are injected.  The materials are fed by gravity from the input end of a converter drum to the discharge end thereof; the input end being elevated above the discharge end.  The converter drum is contained within an outer drum which is in substantially air-tight relationship with the injector for the bales and with a discharge chute for the solid products of pyrolysis.  A casing around the outer stationary drum defines an oven chamber which is heated by combustion products, from a burner providing a heat source, which circulate in heat exchange relationship with a matrix of fins extending into the oven from the stationary outer drum.  A rod extends into the injection end of the converter drum for supporting scrapers against the inner periphery of the converter drum.  A crusher bar is carried in the drum at the discharge end thereof and crushes the solid products which consists of char (mostly carbon black), metals and other non-organic materials.  A chute containing water receives the pulverized discharge product and balances the pressure in the converter to maintain an air-tight seal therein.  A second pyrolysis reactor may receive the solid pyrolysis products and be operative at higher temperature than the first converter to destroy chlorinated hydrocarbons.  To assist in such destruction, lime may be injected into the first converter.  A plurality of converters may be operated in parallel and utilize common equipment for cleaning the product gases released upon pyrolysis and to supply them to the burners of each of the reactors.  Flue gases from the oven chambers of one of the plurality of converters may be supplied to the burner of the next converter for preheating gases for combustion therein.
