Abstract: A wood pulp grinder includes a grinder housing for supporting wood to be ground above a grindstone. A main press chamber in the grinder housing supports a main press ram which moves toward and away from the grindstone. When the main press ram is upraised, the main press chamber is charged with wood to be ground. Adjacent one or both circumferential sides of the main press chamber is disposed a respective auxiliary press ram with is movable toward the grindstone independently of the motion of the main press ram for retaining pressure upon the wood in the grinder housing while the main press ram is not pressing upon the wood. The auxiliary press ram or rams are relatively long in a lengthwise direction, having a length equal to fifty percent and preferably at least eighty percent of their active press stroke. The active lower surface of the auxiliary press ram may be inclined generally in a direction tangent to the surface of the grindstone or may be curved convexly toward the grindstone. When the main press ram is being retracted for reloading the press chamber, a closure plate moves across the bottom of the press chamber for preventing reverse movement of the wood.

Abstract: The invention relates to a method and apparatus for on-machine winding of a web, in which a Pope reeling drum (10) is used, over which the web (W) to be wound passes. A reel spool (11) is driven by so-called centre drive. New reel spools (11 min ) are brought into connection with the reeling drum, after which the web (W) is conducted away from a fully wound roll to be wound onto a new reel spool. The method comprises, in combination, the following steps: an empty reel spool (11 min ) is brought into the grip of primary arms in such a way that bearing members (25) at both ends of the reel spool (11 min ) are being supported by guiding elements at each end of the reeling drum (10) in such a manner that the outer shell of the reel spool (11 min ) is not engaged with the reeling drum (10). The empty reel spool (11 min ), preaccelerated to winding speed, is brought into nip contact with the rotating reeling drum (10), the web (W) to be wounded running through the nip. Due to said nip contact, or only after it, the web breaks off or is severed by means of a double-sided adhesive tape wrapped round the reel spool (11 min ), whereby the web (W) begins to wind onto the empty reel spool (11) and the winding is continued by centre drive of the reel spool (11) and/or nip drive until the roll is fully wound, after which the above steps are repeated.

Abstract: The invention relates to the linkage of the running gear 2 and 3 and the frame 1 of a railway vehicle with wheel sets clamped securely via axle bearings in a running gear frame 4 and 5, the frame 1 being linked to the running gear frame 4 and 5 via leaf carrying springs 6 and open link suspension 7 without a bogie pin and a frictional rotation restrictor 8 being arranged between the running gear frames 4 and 5 and frame 1. The object of the invention consists in designing the link between the running gear 2 and 3 and frame 1 in such a way that, even when the axle is partially or completely relieved of load or the axle suspension loads, the leaf carrying springs 6 of the running gear 2 and 3 and thus the suspension of the open links 7 are stressed to such an extent that a sufficient restoring effect and a sufficiently large rotational restriction of the running gear 2 and 3 are maintained. This object is achieved in that, between running gear frames 4 and 5 and frame 1, a spring 10 is arranged which clamps said frames to one another and is acted upon inversely proportional to the stress of the leaf carrying springs 6 of the running gear 2 and 3. <IMAGE>

Title: Eccentric face seal with asymmetric closing force
Inventor: METCALFE RAYMOND
IPC: F16J15/34
Filed: 1990-08-16
Granted: 2001-02-13
Abstract: An eccentric face seal for rotary machines in which the closing force of the seal faces towards one another is asymmetric. The asymmetric closing force is utilized to produce corresponding variations in the face seal gap which tends to produce fluid flow across the seal face in a direction opposite to the leakage produced by the pressure difference, and thereby eliminate or reduce leakage. Closing forces can be applied by at least a pair of springs providing different compressive forces or by hydraulic actuator means in which the total combined forces can readily be made to vary with fluid operating pressure. In one embodiment the hydraulic actuator means are provided by asymmetric pressure responsive areas of the rotor or stator.

Title: Digital telephone system circuits
Inventor: WISNIEWSKI JAMES J
IPC: H04J3/12
Filed: 1990-10-10
Granted: 2000-06-20
Abstract: A telephone system uses above voice-band ASK control and supervisory signals which are appended to digitally encoded voice by forcing the least significant bits to a selected level for transmission to the receiving end. At the receiving end, the ASK is regenerated by a circuit including special filter. To eliminate audible noise resulting from the filter action, the ASK signal is applied to a shaping circuit which shapes the leading and trailing ASK envelope into a gradually increasing and decreasing envelope. To detect the proper number of pulses in the signal, a threshold detector is used which follows the envelope, ignoring peaks of low amplitude after peaks of high amplitude.

Title: Interface circuits for electromagnetic position transducers
Inventor: NEAD THOMAS E
IPC: G01D5/245
Filed: 1991-08-02
Granted: 1997-01-14
Abstract: Interface circuits for electromagnetic position transducers are provided to reduce the effects of capacitive coupling occurring in the conductive cabling between the position transducers and the associated interfaces located remotely therefrom. Capacitive coupling of excitation signals to the transducer output signals result in error signals appearing as cyclic error in measured positions. The magnitude of the coupled signals are substantially reduced by providing excitation signals symmetrical with respect to ground. The magnitude of the coupled signals are also reduced by presenting equal impedances relative to ground to the output signal return and signal paths. By reducing the effects of capacitively coupled signals, conducting cables for the excitation signals, and the transducer output signals may be incorporated in a single shielded cable.

The triggering means (72) includes threads (56) located external of the plunger (14) and corresponding threads (38) internal of the barrel (12) of the syringe (10). Upon actuation of the trigger (50), the threads (56) on the plunger (14) are retracted from their position of engagement with the threads (38) on the barrel (12), thereby placing the syringe (10) in position for free sliding movement of the plunger (14) with respect to the barrel (12). In the restricted position, the plunger (14) may be screwed into or out of the barrel (12) by rotating the plunger (14), enabling the operator of the syringe t o maintain strict control over the amount of pressure in the syringe.

Granted: 1998-06-30
Abstract: A high speed, high density, low power dissipation all parallel FET logic circuit includes a driving stage having a plurality of parallel FETs of a first conductivity type for receiving logic input signals and a load FET of second conductivity type connected to the common output of the driving stage. A complementary FET inverter including serially connected FETs of first and second conductivity type is connected to the common output and the load FET. According to the invention the voltage transfer function of the complementary inverter is skewed so that the product of the carrier mobility and the ratio of channel width to length of the inverter FET of the first conductivity type is made substantially greater than the product of the carrier mobility and the ratio of channel width to length of the inverter FET of the second conductivity type. By skewing the voltage transfer function of the complementary inverter the voltage lift-off interval is dramatically decreased, thereby improving the speed. AND and OR circuits and combined AND-OR circuits may be provided, having true and complement outputs. A multigate serial load transistor may further reduce power consumption.
