IPC: F16D27/115
Filed: 1994-02-24
Granted: 1997-08-26
Abstract: A connecting system which includes a pilot clutch brought into an engaged state by an actuator, a cam member operated by an engaging force of the pilot clutch, an urging member driven and moved by the cam member, and a main clutch brought into an engaged state by a movement of the urging member.  The cam member includes a first cam ring restrained by the pilot clutch,  a second cam ring provided on the urging member,  and rolling members interposed the first and second cam rings for converting the relative rotation of the cam rings into a thrust.  The system further includes a biasing member for biasing the urging member and the first cam ring in a direction of abutment against each other in order to generate a frictional force between the urging member and the first cam ring.  Thus, it is possible to prevent the engaging force of the main clutch from being influenced by a drag torque produced in the pilot clutch.

Abstract: In a frequency synthesizer, a first pulse removing circuit (31) is connected between a reference signal generator (21) and a phase-frequency comparator (24). A second pulse removing circuit (32) is connected between a variable frequency divider (23) and the phase-frequency comparator. Responsive to first removing data indicative of a first pulse number, the first pulse removing circuit removes pulses from the reference signal that are equal in number to the first pulse number for a first predetermined cycle to produce a first pulse removed signal. Responsive to second removing data indicative of a second pulse number, the second pulse removing circuit removes pulses from the divided signal that are equal in number to the second pulse number for a second predetermined cycle to produce a second pulse removed signal. Responsive to a current command, a current controlling circuit may control current supplied from/to a charge pump circuit (25). A control circuit may be connected between the phase-frequency comparator and the charge pump circuit. A switch may be inserted between the loop filter and the voltage controlled oscillator. When the switch switches off a PLL, a D/A converter supplies a control voltage to the voltage controlled oscillator and a filter capacitor of the loop filter. The charge pump circuit may comprise a control circuit, a constant current circuit, an integrating circuit, and a sample and hold circuit.

Title: Brine seal for tubular filter
Inventor: HEMP MELVIN R
IPC: B01D27/08
Filed: 1995-02-13
Granted: 2000-01-18
Abstract: A filter assembly is provided for a manifolded water filtration system and includes a filter element, a brine seal located at the top of the filter element and engaging a boss depending from the system manifold. The brine seal isolates a rinse water discharge port, communicating with an outlet of the filter element, from an untreated water inlet port formed in the boss so as to ensure that the water to be treated passes through the filter membrane as opposed to directly out of the rinse water discharge port. This configuration eliminates the need for an exterior feed line, thus simplifying the system and preventing vibration during system start-up.      The brine seal also structurally reinforces the filter element, facilitates assembly of the filter, increases the capacity of the assembly, and reduces the chances of failure and leakage.

Title: Apparatus and method for dynamic resource allocation in wireless communication networks utilizing ordered borrowing
Inventor: BENVENISTE MATHILDE
IPC: H04B7/26
Filed: 1995-04-19
Granted: 1999-06-15
Abstract: A communications system and method of ordered borrowing which facilitates dynamic access to a global channel set that has been partitioned into subsets, with each cell of the system being assigned a particular subset of the channel set.  The assignment of channel subsets is performed in such a way as to respect various constraints imposed by the physical layout.  Calls originating in a cell are first assigned to the channels allocated to the base station of that cell, in an order determined by the cell.  Once the allotted channels are exhausted, i.e. in the busy state, the cell attempts to borrow channels from those allotted to the base stations of neighboring cells in a specified order.  The borrowing cell borrows a specified number of channels from each neighbor before returning to a particular cell to borrow additional channels.  The channels borrowed from a neighbor are accessed in an order which is substantially the reverse of the order in which they are accessed by the owner cell. This prescribes, for each cell, a prespecified order in which the entire set of channels may be accessed by calls originating in that cell.

Abstract: Improved steam generating apparatus in the form of a thin, compact generally self-contained wall-mountable fixture.  The fixture includes an upright front face section of porcelain or the like for being mounted in the wall of a shower or other enclosed steam room.  The fixture further includes a frame that is fixed to the rear of the face section and supports a closed steam tank or boiler.  A steam line delivers live steam from the boiler into the steam room.  An improved steam head delivers the steam safely and with minimum noise.   The fixture may also include a mirror and be mounted so that the mirror is face height of a standing user.  The mirror is positioned adjacent to the boiler so that heat radiated from the boiler warms the mirror and inhibits it becoming fogged over by the steam in the room.  The fixture also includes an electrical control system that is operable by the user from inside the steam room.  The control system automatically maintains the user-preselected steam room temperature by regulating the power to the boiler so that steam is generated without interruption and after equilibrium is reached there are no noticeable changes in the room temperature.

Patent CA-2186959-C (CA)
Inventor: VAN GOOR FREDERIK ALBERT
IPC: H01S3/0977
Filed: 1996-02-01
Granted: 2006-01-24
Abstract: Described are a method for generating a laser beam and a laser device for   the method. In a first step gas is ionised by means of X-rays. In a second step the electron density is increased by means of a pre-discharge. In a third step the main discharge takes place. Between the second and third steps, am electron redistribution occurs. According to the invention, the electron redistribution rate and/or the time delay between the pre-discharge and the main discharge are adjustable and controllable in relation to each other, for achieving a particular desired beam profile, such as a uniform profile. Because that delay is preferably set by varying one or more process parameters, an important advantage is achieved in that it is possible with one and the same laser device to modify the beam profile in a simple and flexible manner even during the operation of the laser device.
