Patent CA-2119098-A1 (CA)
Title: Waste liquid evaporator
Inventor: LINTON PAUL
IPC: F24H1/10
Filed: 1994-03-15
Abstract: Abstract The invented waste liquid evaporator includes a burner for producing a flame and a liquid injector for injecting waste liquid directly into the flame. The flame vaporizes the liquid, burns pollutants in the liquid, and produces a vapor exhaust stream. A tank catches the vapor and any waste liquid that was not vaporized. The vapor leaves the tank through a vent, after which it can be exhausted to atmosphere or condensed for recovery. Any liquid in the tank, either from condensation, waste liquid that was not vaporized, or other sources, is also heated for evaporation. The invented method includes the steps of producing a flame, injecting waste liquid directly into the flame to burn at least a part of any combustible pollutants in the waste liquid and to volatilize the waste liquid, providing a tank, catching in the tank the waste liquid and the vapor after the waste liquid is injected into the flame, and providing a vent in the tank to allow the vapor to leave the tank.

Title: Golf Ball Teeing Device
Inventor: DERMOTT JOHN R
IPC: A63B57/10
Filed: 1994-03-23
Abstract: A device for teeing a golf ball automatically and in portable form. It is a complete unit consisting of a hopper for holding a plurality of balls, guides and blockers to prevent the balls clogging in the hopper, a rotor and pendulum to release one ball at a time, an automatic actuation of the ball release, a pivoting ramp to place a ball on an integral tee and a connection to the tee so that when the ball is struck with a golf club, the next ball will automatically proceed to the tee. The flow of a ball to the tee is accomplished by gravity due to the elevated hopper and the force of the golfer's swing. The device is mechanical and does not require electric power nor batteries and is completely automatic since no separate operation is required to send the ball to the tee.

Title: Recreational vehicle having convertible frontal seating to provide dinette and sleeping facilities
Inventor: HANEMAAYER JACOBUS N
IPC: B60P3/34
Filed: 1994-06-09
Abstract: A system or structure allowing conversion of the front area seating of a van to a dinette for two and/or four persons and to a single and/or double bed.   The structures provided  enable the front passenger seat to rotate 360 degrees and slide over a position adjacent to the driver seat which also can be rotated 360 degrees. The single seat directly behind the driver seat can be extended sideways to form a double seat.   The table in between the front seats and seat directly behind these seats is cantilevered from a wall cabinet located below the window,  which is located in the exterior sidewall directly behind the driver seat.  This table is removable at will for storage in a coat closet or lowered to serve as a base for a single or double bed.  The two part hinged front leaf may be folded back over the main rear leaf to allow ample space for the driver seat to slide back and forth on tracks when in the forward driving position. When the table is lowered to the bed base position, the rear seat cushion(s) is moved forward thereby resting on the lowered table.  The back rest(s) is lowered into the location of the seat cushion.   The two front seats are rotated to face one another with the passenger seat slid over to a position directly adjacent the driver seat.  The arrangement makes for a double bed or a single bed if only the driver seat and the cushions (without the extensions) of the rear seating are used.
Patent CA-2125939-A1 (CA)
Inventor: MALOTA BERNHARD
IPC: H03F1/32
Filed: 1994-06-15
Abstract: At high frequencies, the video signal requires a higher current. For this purpose, it would be necessary to operate the video output stage with a higher quiescent current. Since these high frequencies are rarely required, the object is to provide a circuit which makes it possible to select the operating point when the frequency is increasing. For this purpose, a controlled variable which controls the operating point of the amplifier stage is obtained in dependence on the frequency output to which the amplifier stage is driven.      The distortion-free display of video signals with a large proportion of high frequencies, in particular on screens of cathode-ray tubes, is thus possible with little outlay on components.     In particular video amplifiers for projection picture tubes.

Filed: 1994-07-25
Abstract: A radio transceiver having an integrated transmitter and receiver for transmitting and receiving microwaves or higher frequency electromagnetic waves is one of a series of device products corresponding to different transmission output power capacities. In this invented series of device products, a radio transceiver which is of a minimum size to meet its transmission output power requirement without an amplifier is composed of entirely standardized basic components, a transmission module, a reception module, and a transmission and reception shared circuit which are housed in a heat radiating housing case irrespective of different transmission output power requirements. Corresponding to the transmission output pawer requirement, a power amplifier is added to the basic components. The heat radiating housing case which houses the basic components and the power amplifier is longer than, but has the same cross section as, the heat radiating housing case which houses no power amplifier, thereby radiating the heat produced by the power amplifier. The heat radiating housing case is thus substantially standardized.

Abstract: ELECTRICAL CONNECTOR INLET ASSEMBLY WITH      BREAK-AWAY MECHANISM FOR ELECTRIC VEHICLE                 ABSTRACT OF THE DISCLOSURE      An electrical connector inlet assembly with a break-away mechanism coupled to an electric vehicle for receiving electrical energy.   The break-away mechanism disconnects the contacts of the inlet assembly or receptacle from the contacts of the plug to prevent damage of the electrical connector assembly, upon application of a highly excessive force pulling the plug away from the receptacle prior to disengagement of the contacts.  The electrical connector inlet assembly receives an electrical connector or plug with electrical contacts for mating with the electrical contacts of the electrical inlet assembly or receptacle. The  plug  has  a  cover  for  selectively  covering  and uncovering its electrical contacts to prevent inadvertent contact with the electrical contacts and to protect the electrical contacts from the environment.  Likewise, the receptacle  has  a  cover  for  selectively  covering  and uncovering its electrical contacts to prevent inadvertent contact with the electrical contacts and to protect the electrical contacts from the environment.  In the preferred embodiment,  the covers of the plug and receptacle are either automatically or manually uncovered only after full insertion of the plug into the receptacle.  The plug can be inserted into the receptacle with little or no force by the user since the contacts of the plug and receptacle are not electrically coupled together until after full insertion of the plug into the receptacle.

Title: Picture encoding method, picture encoding apparatus and picture recording medium
Inventor: ODA TSUYOSHI
IPC: H04N19/177
Filed: 1994-04-11
Abstract: A mechanism for encoding an input video signal, e.g. predictive encoding, or DCT processing, based on a fixed quantization step size and variable length encoding. A first bit stream is generated and an encoding rate corresponding to a predetermined period is determined based on (1) the quantity of available data associated with the first bit stream, (2) the encoding difficulty, and (3) the quantity of usable data. Further on, the input video signal is quantized based on the encoding rate previously determined, and then variable length encoding is performed to generate a second bit stream. Thus, a variable rate is obtained as the encoding rate changes every predetermined period. In the case when the second bit stream is recorded onto picture recording media, the memory capacity is efficiently used and the recording time is extended. Even when pictures of a complicated pattern are successive, the quantization step size does not become too large and therefore, uniform high quality picture is obtained throughout the entire transmission.

Abstract: A unitary suspension clip for suspending gypsum board panels from the horizontal channel member of an erect support structure.   The plate portion of the clip has panel-piercing members projecting rearwardly to affix the plate to the panel.  A transverse line of weakness extends substantially across the width of the plate such that when the panel is suspended from the channel member, the load applied between the channel member and the plate causes the plate to bend therealong to prevent the pulling of the panel-piercing members out of the panel.  A wing is formed along the edge of the plate and extends outwardly therefrom with  a  second  line  of  weakness  running  in  the  same direction as the edge of the plate between the wing and the plate.  The wing is bent at the second line of weakness upwardly from the surface of the gypsum board panel and has an  angled  surface  formed  therein  which  rests  on  the horizontal channel member and causes the panel to be drawn into engagement with the erect support structure.

Title: System and method for distributed computation based upon movement, execution and interaction of processes in a network
Inventor: WHITE JAMES E
IPC: G06F9/50
Filed: 1994-07-08
Abstract: A distributed computing environment in which agent processes (150A) direct their own movement through a computer network (100). Place processes (220A, 220B) provide a computing context within which agent processes (150A) are interpreted. An agent process (150A) controls its movement from one place process (220A) to another (220B) within the network (100) by using a ticket (1306). An agent process (150A) which moves from one place process (220A) to another (220B) transports definitions of classes of which objects included in the agent process (150A) are members. An agent process (150A) which moves from one place process (220A) to a second place process (220B) avoids unnecessary transportation of objects included in the agent process (150A) by substituting equivalent objects which are found in the second place process (220B).
