Abstract: ABSTRACT OF THE DISCLOSURE      A package (10) includes a polyethylene terephthalate (PET) container (12) having a necked opening (14).  A PET insert (18) is fixedly attached to an inside surface (30) of the necked opening (14) by a plurality of tack welds (34).  The insert (18) makes a substantially line contact (32) with the inside surface  (30) of the necked opening (14).  The substantially line contact (32) extends contin-uously  around  the  in side  surface  (30)  of the  necked opening (14) to form a fluid tight seal between the inside surface  (30)  of the necked opening  (14)  and the insert (18).  To make the package (10), the insert (18) is driven into the necked opening  (14).  The tack welds  (34)  are formed between the necked opening (14) and the insert (18) by application of ultrasonic energy at the necked opening (14)  below the line contact  (32).  The tack welds  (34) fixedly  attach  the  insert  (18)  to  the  necked  opening (14).

Abstract: ABSTRACT        A remotely controlled mobile target for weapons training involves a commercially available all-terrain-vehicle carrying a 1/2 scale target shell (e.g. a tank).          The vehicle has a motor and a brake-generated skid steering system.  A video camera mounted on the vehicle provides the operator at the remote station with a visual image of the vehicle's progress and in response thereto the operator, using a joystick controller, can send command signals to the vehicle to control operation of the steering system and the motor.  Three way solenoid valves, connected to the hydraulic brake system, a source of compressed gas and the electronic controller operate in response to the command signals to effect operation of the brakes for steering or braking.  The target is inexpensive, easy to operate and closely simulates the operation of a highly maneuverable, fast vehicle, such as a tank.

Abstract: PROCESS FOR THE ELECTRICAL EXCITATION OF A LASER GAS     Abstract of the Disclosure In order to prevent, in the microwave excitation of a laser gas, the development of wall boundary layers and to attain a homogeneously large volume plasma, the laser gas is delivered in the inclusion zone of the microwave after passing a current-forming element where it is ignited by a coaxial wave guide ar-rangement.   The ignited laser gas then spreads with the micro-wave  in the discharge segment where it produces a homogeneous, excited laser-active medium.   The homogeneity is additionally improved with the operation of the microwave guide near the "cut-off-width".

Abstract: GOLF PRACTICE DEVICE          ABSTRACT OF THE DISCLOSURE   A narrow strip (15) of one component of "hook and loop" fastener material is detachably secured across the face  (14,  14A)  of any conventional golf club  (10) covering the  striking zone.   A target object  (16)  is formed from the other component by forming a strip into a hollow  circular  ring  and  joining  the  ends  by  any conventional  manner  such  as  adhesive.    The width  is substantially narrower than the diameter and the diameter is substantially equal to the diameter of a golf ball.          When  the  club  strikes  the  target  object  the  two components co-act to detachably secure one to the other so that the player can see the exact position of the engagement of the club head with the target object.  The sound of the golf club head striking the target object makes a sound similar to striking a conventional ball with the club, and the strip on the club head is easily removed and is reusable on the same or other clubs.

Title: Auxiliary power system for trucks and other heavy duty vehicles
Inventor: NIJJAR PARMJIT S
IPC: F02N19/10
Filed: 1988-11-15
Granted: 1993-04-27
Abstract: ABSTRACT            An auxiliary power system for a truck or other heavy duty vehicle.   A secondary engine which is smaller than the vehicle's  main  engine  is  used  to  generate  heat  and electrical  power,  and  to  drive  an  auxiliary  air conditioning  system. The  coolant  systems  of  the  two engines are interconnected so that when the main engine is off and the secondary engine is on, waste heat from the secondary engine is transferred by coolant flowing through the water jacket of the secondary engine to the main engine and also to heater cores in the truck's cab and sleeper. An  electrical  generator driven by the secondary engine provides electrical energy.  The auxiliary air conditioning system includes an auxiliary compressor and an auxiliary condenser, and connections for efficiently interconnecting the  auxiliary air conditioning  system with the truck's primary  air  conditioning  system.    The  auxiliary power system permits the use of a small and efficient engine to keep the truck's main engine and cab warm and to run a variety of other accessories without having to run the truck's main engine.

Granted: 1992-05-26
Abstract: "High Throughput Communication Method and System for a Digital Mobile Station When Crossing a Zone Boundary During a Session"     ABSTRACT OF THE DISCLOSURE In a digital radio communications system, a mobile station in the service zone of a first base station transmits a reconnect request packet to a second base station when leaving the service zone of the first and entering the service zone of the second during a session with the first base station. The second base station communicates the receipt of the reconnect request packet to the central station, from which a proceed-to-clear command packet is sent to the first base station to allow it clear the connection with the mobile station and return a clear response packet to the central station informing it of a serial number of the last data packet it has received from the mobile station immediately before leaving its service zone. On receiving the clear response packet, the central station sends a reconnect command packet indicating that serial number to the second base station to cause it to issue a reconnect response packet to the mobile station requesting the reconnect. The reconnect response packet communicates the serial number of the last packet to the mobile station to allow it to send a copy of data packets which may have been interrupted during the session with the first base station.

Crichlow ABSTRACT OF THE DISCLOSURE           Ruminal lactic acidosis develops in ruminant animals following the ingestion of large amounts of unac-customed feeds that are rich in readily fermentable carbo-hydrates.  Characteristic symptoms of this disease include systemic acidosis, ruminal acidosis, forestomach stasis or forestomach hypomotility, inappetence, depression and hemoconcentration.  Alpha-2 adrenoceptor antagonists have been found to be capable of re-establishing forestomach motility that has been lost or severely diminished in ruminants suffering from ruminal lactic acidosis.  These antagonist compounds have also been found to be effective in the treatment of ruminants experiencing ruminal lactic acidosis.
