Title: Cellulose fibres
Inventor: RUEF HARTMUT
IPC: D04H3/14
Filed: 1994-07-08
Abstract: The invention concerns a method of manufacturing cellulose fibres by extruding a solution of cellulose in a tertiary-amine oxide through the holes of a spinneret and passing the extruded filaments under tension through an air gap into a regenerating bath. The method is characterized in that it is is carried out in such a way that the maximum value of the mathematical expression 51.4 + 0.033xD + 1937xM<2> - 7.18xT - 0.094xL - 2.50xF + 0.045xF<2> in which D is the spinneret-hole diameter in  mu m, M is the spinning-solution throughput per hole in g/min, T is the titre of a single filament in dtex, L is the length of the air gap in mm and F is the humidity of the air in the air gap in g of water per kg of air, is 10, with the provision that the length of the air gap is greater than 30 mm. This method gives cellulose fibres with a very low tendency to fibrillation.

Title: Swing-stop control method for a crane
Inventor: SHIBATA NAOTAKE
IPC: B66C13/06
Filed: 1995-04-27
Abstract: A swing-stop control method for a suspension crane comprising a running device for driving and running a trolley and a hoisting device, comprising the steps of inducing a conditional equation for damping the swing of a suspended load as a function of a driving speed command for the running device, a signal from a suspended load running direction speed detector and a measured length value of a hoisting rope for a suspended load and controlling the trolley running speed in accordance with a running speed command signal corrected such that a position error signal approaches 0 which is calculated using a position error function from an optimal position for the trolley obtained from the conditional equation so as to stop the swing, whereby the periodical swing of the suspended load is sufficiently controlled to thereby stop the suspended load at a target position with good accuracy and less swing. The swinging movement of a rope is controlled which is generated when the trolley is driven to be accelerated or decelerated, thereby making it possible to attain the automatic operation of the crane with the running speed of the trolley maintained high. <IMAGE>

Title: Indicator gauge assembly
Inventor: BIRKS RODNEY CHARLES
IPC: G01D3/10
Filed: 1996-10-02
Abstract: An indicator gauge assembly comprises master and slave air-cored indicator gauges 10,11, each having a pointer whose position is dependent upon the current flowing through the respective coil L3. The coil L3 of the master gauge 10 is connected in parallel with a transducer S which varies in resistance depending on the value of the parameter being measured, thereby correspondingly varying the coil current so that the gauge pointer moves. The slave gauge 11 comprises a voltage follower circuit 20 having a high impedance input connected across the coil L3 of the master gauge 10, the output of the voltage follower circuit 20 being connected across the coil L3 of the slave gauge 11. The voltage follower 20 creates a voltage across the coil L3 of the slave gauge 11 which corresponds with that across the coil L3 of the master gauge 10, so that the current through the coil L3 of the slave gauge 11 is the same as that flowing through the coil L3 of the master gauge 10. In this manner the two gauges 10, 11 give the same reading while the connection of the slave gauge does not affect the reading given by the master gauge.

Title: Combined system for venting fuel tank, and regulating fuel supply according to state of air filter
Inventor: ZERRER GERHARD
IPC: B27B17/00
Filed: 1997-01-29
Abstract: A cutting-off tool, e.g. a chainsaw, has an i.c. engine 11 located in a housing. Carburettor 35 supplies fuel/air mixture to the engine. The carburettor is connected through induction port 36 to the clean air side 34 of an air filter 37, and sucks fuel from a fuel-filled control chamber 33. The fuel enters this chamber from tank 10 through pipe 27, pump 29, and inlet valve 32, which is controlled by diaphragm 31. This diaphragm defines a compensation chamber 20, which is connected by compensation line 21 to the clean air side of the air filter. This reduces fuel supply proportionately to reduced air supply as the air filter becomes clogged. Tank 10 is also connected by line 8 and throttle 4 to overflow reservoir 9. Rather than opening air valve 17 to atmosphere, it is connected by pipe 15 to compensation line 21. As fuel vapour does not escape to atmosphere, fire risk is reduced.

Title: Audio signal processing; reverberation units and stereo panpots
Inventor: FRINDLE PAUL ANTHONY
IPC: H04S1/00
Filed: 1998-09-23
Abstract: A user-controllable panpot type device 140 causes an input audio signal 145 to be routed into a plurality of paths 200, 210 with relative signal amplitudes corresponding to a current control setting of the panpot 140, and time delay means 180, 190 are also controlled by the panpot 140 to apply a relative delay between the signals routed into the paths 200, 210, the relative delay being related to the respective signal amplitudes in the different paths. The time delays are arranged so that the delay in a path 200 or 210 increases as the relative signal amplitude in that path decreases (Fig.3). In a stereo system in which the paths 200 and 210 form the left hand and right hand signals, the position of a virtual sound source as subconsciously assessed by a user from the relative signal amplitudes corresponds to the position as assessed from the relative time delay. A reverberation unit (Fig.4) has a similar arrangement with an input signal being split into multiple paths controlled by a panpot to give different relative amplitudes in different paths and time delays which increase as relative amplitude decreases, the signals in the multiple paths being combined. Different positions of the panpot represent different positions of a sound source in a reverberant venue. A panpot (370, Fig.6) constructed as part of a mixing console (380) may control a separate outboard reverberation unit (410).
