Title: Low pressure, high volume pressurized water gun
Inventor: JOHNSON LONNIE G
IPC: B05B9/08
Filed: 1993-03-26
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention is a toy water gun having a housing with extending handle, a release mechanism and barrel.  The water gun is connected to at least one water source external from and connected to the housing.  In preferred embodiments, the water source is remote and has an indirect connection, e.g. by tubing or hosing, external of said housing and having a vent to surrounding ambient air so air may enter therethrough.  Also included is a pressurized air and water storage tank external from and connectable to the housing.  The pressurized tank has an orifice between said pressurized tank and said housing through which all liquids and gasses pass.  There is also a pumping means for withdrawing air or water from the source or sources, and for depositing the withdrawn air or water into the pressurized tank.  A plurality of one-way flow valves is included wherein at least one one way flow valve prohibits water and air from flowing from the pressurized tank to the pumping means, at least one said one-way flow valve prohibits water and air from flowing from the pumping means to the source or sources of air and water.  There is a nozzle with a wide orifice therethrough, which affixed to the end of said barrel and an avenue of release connecting the nozzle to the pressurized tank.  There is also a controlling means for regulating the flow of water and air through the avenue of release, the controlling means being actuatable by a release mechanism.

Title: Radio communication systems
Inventor: BAYES TERENCE
IPC: H04B7/26
Filed: 1993-04-07
Abstract: ABSTRACT.             RADIO COMMUNICATION SYSTEMS     A code division multiple access (CDMA) system wherein communication between a base station and a plurality of hand sets is effected at a common carrier frequency utilising time division duplex to afford accurate power control and to obviate the 'near far' problem. Preferably a pilot signal is added to the transmissions from the base station. This is used to sound the channel, providing a measure of the channel impulse response from base station to each hand set receiver. This information is then used to set up an inverse filter, which is applied to the receiver signal prior to detection. The detrimental effects of the channel can be removed, restoring orthogonality to a received code set and thus giving optimum capacity. In the reverse link a pilot can be used to predistort each hand set signal prior to transmission, according to the unique channel impulse response measurement made at each hand set. Since the filtering operations are assumed linear the order may be interchanged, and the base station receives each hand set signal with the detrimental effects of the channel precompensated. Orthogonality between hand set transmissions is therefore achieved at the base station receiver. Capacity is therefore balanced in forward and reverse links and the constraint of power control may be somewhat relaxed.
Patent CA-2098796-A1 (CA)
Title: Method and apparatus for cementing intramedually bone prosthesis
Inventor: CARBONE JOHN J
IPC: A61F2/00
Filed: 1993-06-18
Abstract: An intramedullary bone prosthesis to be rigidly cemented into position in the femur, and also applicable to total knee and shoulder replacement operations, is provided as an improved surgical technique. The prosthesis is composed of a femoral head base, a femoral head post, a long femoral stem, a cement canal along its longitudinal axis, a spacer, a collar, and a distal restrictor. The prosthesis is placed into the prepared medullary canal. With collar in position, a bone cement injector is readily threaded on to the proximal portion of the cement canal. Cement is injected and subsequently travels down through the canal, through the spacer, and eventually exits openings at the bottom of the spacer. The distal restrictor plug halts downward cement travel, thus initiating an upward, retrograde filling of the void in between the prosthesis and the cancellous bone wall.      The cement reaches the collar or cement restrictor, thus proximally dislodging all air bubbles, blood, and blood products. Finally, during curing, the cement in constantly and evenly pressurized by means of the cement injector, and excellent cement interdigitation is achieved.

Filed: 1994-08-03
Abstract: A plastic bag making machine including a cylindrical drum with a variable diameter is disclosed. A plurality of seal bars, substantially parallel to the drum's rotational axis, define the circumference: of the drum. Bags are made from a film that includes registration marks detected by a detector disposed near the film's path. A detector detects the revolution of the drum and an encoder provides signals indicative of the position of the film. A controller determines the distance between the registration marks using the output of an encoder as a position signal and adjusts the diameter of the drum in response to the determined distance. The controller also determines the position of the seal bars relative to the registration marks and adjusts the diameter of the drum in response to the relative position.
