Title: Double tank pinch trigger pump water gun
Inventor: JOHNSON LONNIE GEORGE
IPC: F41B9/00
Filed: 1991-08-20
Abstract: A toy water gun is operated by selectively releasing water from a water reservoir pressurized with air. A manually operated pump 31, 33, 34 is operated by a sliding handle 73. As the pump is cycled, water and air is drawn from a water storage tank 38. Once drawn, the water and air are forced into a pressurized reservoir 3. As the amount of water and air forced into the pressure reservoir increases, the pressure of water within the pressure reservoir 3 increases. The pressure of the water and air within the pressure reservoir increases with each cycle of the pump, until the pump can no longer overcome the pressure of the water and air within the pressure tank. The pressurized water and air within the pressure tank has an avenue of release 67 that is regulated by a trigger 65. When no force is applied to the trigger 65, the pressurized water and air are held at bay by a pinch bar 63. When force is applied to the trigger 65, the water is first released from the pressurized container and is channelled through a narrow nozzle 75. The escape of the water, under pressure, through the narrow nozzle creates a stream of propelled water that lasts as long as the trigger is engaged or until the air pressure propelling the water equals the ambient pressure. <IMAGE>

Title: Means for disconnecting electrical connectors
Inventor: JINNO KEISHI
IPC: H01R13/635
Filed: 1991-08-21
Abstract: A connector comprises a first connector housing (A) having first metal terminals (1), a second connector housing (B) having second metal terminals (11) engagable with the first metal terminals (1) and a lock devices (13, 14) for holding the first and second connector housings together. The first housing (A) includes a slidable spring receiving device (C) for receiving the repulsive force of a spring (6). When the housings (A, B) are engaged, the second housing (B) slides the spring receiving device (C) against the spring force until a device latch (7b) engages a first housing part (8). This holds the spring (6) compressed, while device (C) prevents spring force application against housing (B) and the housings are locked together by devices (13, 14). Pressure on arm (13c) releases devices (13, 14) (7b, 8) so that spring (6) can force device (C) and housing (B) to their disengaged positions. <IMAGE>

Patent GB-921253-A (GB)
IPC: G11B15/28
Abstract: 921,253. Driving magnetic tapes. O. STEIDINGER, and S. STEIDINGER, [trading as GEBRUEDER STEIDINGER KOMM.-GES.]. March 16, 1961 [March 28, 1960], No. 9589/61. Class 40 (2). A tape recorder, in which a capstan 1 is driven by a belt 3, of resilience chosen to reduce wow and flutter transmitted from a motor 4, has a control lever 16, shown in the transducing position D and movable to fast-winding positions C and E. A pinch-roller 6 is engaged with the tape only in the position D. For rewind, C, a roller 18 diverts the belt 3 into contact with a carrier 7 supporting the feed spool; for fast forward wind, E, the roller 18 diverts the belt 3 so that an idler roller 12 is moved to engage the belt and a carrier 8 supporting the take-up spool. The rollers 12, 18 are arranged to avoid contact with the belt and the carrier when non- operative. During transducing, a belt 20 drives a friction disc coupled to the carrier 8 allowing slip (Fig. 2, not shown); during fast wind this drive is overcome. In a further embodiment (Fig. 3, not shown), the slipping drive is supplied by a direct belt drive from the motor.

Abstract: A fuel cell (12) uses hydrogen as a fuel and oxygen as an oxidant and a hollow member (64) is partially located in an anode chamber (30), partially located in a cathode chamber (32) and partially located in a water collecting chamber (88). The hollow member (64) contains-a non electrolyte aqueous solution, e.g. sucrose solution. The hollow member (64) is formed from a semi- permeable membrane which allows water to permeate therethrough but prevents hydrogen, oxygen and the solute e.g. sucrose permeating therethrough. Water transported through a solid polymer electrolyte (36) from the anode chamber (30) to the cathode chamber (32), and water produced in the cathode chamber (32) permeates through the semi-permeable membrane into the hollow member (64) by osmosis. Water in the hollow member (64) permeates through the semi-permeable membrane into the anode chamber (30) and dryer regions of the cathode chamber (32) by osmosis. Water in the hollow member (64) permeates through the semi- permeable membrane into the water collecting chamber (38). A heat management system which dissipates heat from the fuel cell in also disclosed. (fig.4 not shown) <IMAGE>

Title: Pre-equalization in data communication systems
Inventor: CHUNG HONG YANG
IPC: H04L25/03
Filed: 1989-10-26
Abstract: The theoretical coding gain associated with an error correction technique can be realized in a digital communications system employing this error correction by providing the equalization in the transmitter instead of the receiver. In a first embodiment, an automatic equalizer (380, 381) in the receiver (375) of a digital communications system is adjusted using a training sequence. The equalizer coefficients for optimum adjustment are then transmitted back to the transmitter (300) and supplied to an equalizer therein. After the training period is over, this transmitter equalizer, now having optimum coefficients, is activated and the receiver equalizer can be adjusted in response to actual data using "blind" equalization. The generated coefficients, as in the first embodiment, are then transmitted back to the transmitter. In either embodiment, using the transmitter equalizer to predistort the transmitted signal in a manner opposite to that of the communications medium connecting the transmitter and receiver assures that the noise at the input to the receiver decoder is both Gaussian and white. As a result, the theoretical coding gain associated with the employed error correction is substantially realized. The transmitters and receivers also include Nyquist filtering for spectrum shaping, which is controlled to be operative at a location when the equalizer at that location is inoperative. The application described herein relates particularly to multi-point communication systems, although the technique is equally applicable to point-to-point systems. <IMAGE>
