Patent CA-2098930-A1 (CA)
Inventor: RAGNARSSON ANDERS T
IPC: B27L11/00
Filed: 1991-10-25
Abstract: A comminutor for reducing large diameter wood products and stumps to size, comprised of a reduction chamber, with an impact rotor positioned concentrically therein, in combination with a housing, drive motor and infeed chute. The impact rotor is formed with a plurality of horizontally elongated impact hammers at its periphery. The impact hammers are arranged in sets of impact hammer rows oriented at an angle to the rotational axis of the impact rotor. Each set of impact hammers has one row of hammers having radial angles increasing along the rotor's longitudinal axis in the axial direction of the rotor and a second opposing row of hammers having radial angles decreasing along the rotor's longitudinal axis in the axial direction of the rotor. The rotor is positioned so that the elongated wood product or stump falling under the influence of gravity through the infeed chute is directed against the impact hammers, and repelled ahead of the rotor's rotational direction against an anvil formed along one side of the reduction chamber.

Title: Atomic frequency standard cell and method for forming same
Inventor: SCHOLES ADDISON B
IPC: G04F5/14
Filed: 1993-06-22
Abstract: ABSTRACT OF THE DISCLOSURE An atomic frequency standard cell having low helium permeability includes first and second windows sealed by fusible annular gaskets to sealing surfaces defined by a tubular cylindrical body. One of the windows defines an opening, and a fill tube is sealed to the window adjacent the opening by a tube gasket.  The gaskets are made of a lower softening point glass such as borosilicate glass, and the body, windows and fill tube are formed of a higher softening point glass such as aluminosilicate glass.  The assembly is sealed together by heating it to a temperature that causes the gaskets to fuse and seal the adjacent components together.

Title: Liquid soap dispenser for simplified replacement of soap reservoir
Inventor: OPHARDT HEINER
IPC: A47K5/12
Filed: 1993-10-29
Abstract: A  liquid soap dispenser  is disclosed having a permanent housing which permits simplified insertion and replacement of disposable fluid reservoirs.   The housing includes and actuator assembly which is cycled by a lever between first and second positions.   The actuator assembly is configured to couple to a valve assembly on the reservoir so that when cycled,  the valve assembly is actuated  in sliding movement to dispense a quantity of fluid.   The actuator assembly includes a pair of resiliently deformable fingers  which  act  to  secure the valve  assembly  to the actuator assembly for sliding movement therewith.   If on insertion  of  a  replacement  reservoir,  the  reservoir  is positioned uncoupled from the actuator assembly,  on first cycling  of  the  actuator assembly the  fingers  deform to permit movement of the actuator assembly relative to valve assembly and move towards a coupled orientation.   In the coupled orientation,  the fingers return to an undeformed configuration securing the valve assembly to the actuator assembly.

Patent CA-2103543-A1 (CA)
Inventor: MOISIN MIHAIL S
IPC: H05B41/24
Filed: 1992-03-06
Abstract: A circuit (500) for driving series-connected gas discharge lamps from a transformer secondary winding (528) connected at first (529A) and second (529B) points respectively to first (508) and second (514) output terminals across the lamps. A capacitor (532) couples the first point to an intermediate output terminal (512). The pre-strike voltage produced across the secondary winding is applied across a single lamp (506) to cause it to strike. After striking, current to the intermediate output terminal (512) is limited by the capacitor (532), and the lamps are driven in series. In this way, the voltage which needs to be produced across the secondary winding to ensure striking of all lamps is reduced. Alternatively, the output terminals across the lamps may be connected to points on the secondary winding further apart than the first and second points (Fig. 6) or intermediate the first and second points (Figs. 1-4).

Title: Clamping receiver and transmission protocol
Inventor: GELLER WILLIAM L
IPC: H04B10/69
Filed: 1992-03-30
Abstract: Abstract of the Disclosure A protocol for fiber-optic communication systems, or other communication systems based on transmission of unipolar pulses having wide dynamic range provides for information to be transmitted in packets having a predictable time slot for each transmitter. The receiver for such protocol has a first relatively long RC time constant mode conditioned for reception of data packets whose time of arrival is well predictable and a second relatively short RC time constant mode conditioned for reception of asynchronous randomly received packets. In the relatively long RC time constant mode, each packet includes a preamble having a first clamp interval in which no pulse is transmitted, and a second clamp interval in which a continual pulse is transmitted A transducer on the receiver translates the packets of pulses into differential electronic signals on first and second outputs. First and second coupling capacitors, receive respective outputs of the transducer and AC couples the signals to respective second terminals of the capacitors. First and second switches connect the second terminals of the respective coupling capacitors to ground during the first and second clamping intervals, respectively, of the preamble. By clamping the outputs of the transducer to ground during the first and second clamping intervals, a DC level each incoming packet is instantly established independent of the magnitude of the incoming packet. e asynchronous mode, relatively low impedance discharge paths are established to reduce the time constant of the receiver. An output circuit connected to the second terminal of each of the first and second coupling capacitor, supplies sequences of digital output signals in response to the differential signals.

Title: Container bag
Inventor: FUTERMAN CHARLES S
IPC: B65B69/00
Filed: 1993-09-08
Abstract: ABSTRACT     A container bag (10) designed to be inflated before or during filling  characterised in that a pressure relief valve (22) is incorporated or incorporatable into the bag body, the valve being connectible to a receiver  for exhausted powder  or pulverulent matter.  The pressure relief valve can be set to give a desired inflation pressure in the FIBC but will permit air to escape above this pressure thereby ensuring that the stitching and seams of the FIBC are not over-stressed to the point of leakage.  The valve is connectible to, and preferably is connected to, a receiver for any vented gases and entrained powder.  Preferably the receiver is the filling silo (28) so that any expelled powder is returned for refilling.
