Patent CA-2040184-A1 (CA)
Title: Plasma spray device with external powder feed
Inventor: FUIMEFREDDO ANTHONY J
IPC: H05H1/42
Filed: 1991-04-10
Abstract: The front face of the nozzle of a plasma spray device has a shallow annular recession therein. The recession is bounded inwardly by an extended portion of the nozzle, outwardly by a ring member and rearwardly by an inner surface. The ring member has therein a plurality of arcuately equally spaced holes directed radially inward toward the inner face, the holes communicating with a source of air. Powder is injected radially into the plasma stream external to the nozzle member proximate the outlet end. The air flow from the holes and entrainment of surrounding atmosphere by the plasma stream drive a toroidal vortex anchored in the recession, the vortex effecting a wiping flow on the nozzle face such as to inhibit powder from depositing on the nozzle face.

Title: Credit card alarm security system
Inventor: LOMBARDO ORAZIO N
IPC: G08B3/10
Filed: 1991-07-25
Abstract: Abstract:     The credit card alarm security system is a unit that holds a certain number of credit cards, that number depending on the model of the wallet.  What differentiates this invention from other wallets is that the user will be warned if the card is not returned to its place.     This will eliminate the chance of forgetting a credit card at a cash register after having charged a purchase, or using a bank card at an automatic teller, or any other such circumstance.     This system may be employed in models ranging from wallets - pocket books - to purses and cases of all types.

Title: Feed arrangement for a harvester
Inventor: ANDREASSON OLOF
IPC: A01G23/00
Filed: 1991-11-27
Abstract: ABSTRACT            An arrangement for the feeding and guiding of tree trunks in conjunction with the delimbing of the trunk operates with moving feed belts 22 arranged opposite one another on either side of the trunk, which feed belts drive the tree trunk by friction in its longitudinal direction through a delimbing unit, where branches are removed from the tree. the feed belt is in the form of an endless belt which is attached along its lateral edges 23 to drive chains 20 engaging with toothed rings 24 on two separate feed wheels 7. A rectilinear section of the feed belt is held under pressure in flexible contact with the trunk 1 as friction is developed over a relatively large area.      The large friction surface between the feed belt and the trunk means that the necessary force for feeding the trunk can be achieved without the risk of damage to the surface layer of the trunk.

Title: Insect trap light cover
Inventor: HAGLOCH RALPH S
IPC: A01M1/04
Filed: 1992-04-30
Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates in general to lighting fixture devices, and in particular to the covers over lighting fixture bulbs   It relates to an entryway,  with funnel-like characteristics,  located in the surface of a lighting fixture cover, flared inward, terminating in a small port near the bulb.  Its purpose is to trap insects inside the light  cover.    It  may  be  constructed  in  various  shapes,   or combination of shapes,  resulting in a funnel-like characteristic, which  affords  easy access  to  the  light  source,  but  practically prevents  insects  from  exiting  via   the  same  route.   It   is aesthetically, or mechanically, free-form in shape and construction.          It may be constructed of various  clear or  translucent materials suitable for lighting fixture covers.   It may also be incorporated into an existing lighting fixture cover,  or into an adapter which fits  between an  existing  lighting fixture and  its  cover.    Its practical  use  is  as  an  alternate  method  of  controlling  flying insects around lights in patio areas and exterior doors,  in food storage areas, in trash areas, and in gardens.

Title: Head pressure controller for air conditioning and refrigeration system
IPC: F24F11/02
Filed: 1992-05-07
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention describes a method of controlling the head pressure in a refrigeration or air conditioning system in order to maintain the internal discharge pressure and discharge line pressure substantially equal.  The method consists of the steps of measuring the suction pressure of the working fluid, calculating the internal discharge pressure of the working fluid by multiplying the suction pressure by the internal pressure ratio of the compressor, measuring the discharge line pressure of the working fluid and then comparing the internal discharge pressure to the discharge line pressure.  If the difference between the internal discharge pressure and discharge line pressure is greater than some allowable tolerance, the capacity of the condenser is adjusted to equalize these two pressures.

Patent CA-2083615-A1 (CA)
Inventor: MAEDA SHIGEMI
IPC: G11B20/00
Filed: 1992-11-23
Abstract: A data recording/reproducing apparatus uses a single recording medium in which absolute address data have been previously formed. Also, the data recording/reproducing apparatus has a first memory for recording and a second memory for reproducing. Audio data reproduced from the recording medium is stored in the second memory at a first transfer rate, and the audio data stored in the second memory is sequentially read at a second transfer rate lower than the first transfer rate for audio-reproduction. Meanwhile, audio data input from an external source is sequentially stored in the first memory at the second rate, and the audio data stored in the first memory is read at the first transfer rate for recording on the recording medium. The aforementioned reproducing and recording operations are alternately repeated. Thus, the data recording/reproducing apparatus allows an audio data recording operation to be concurrently performed during audio reproduction with the single recording medium.
