Patent DE-4034067-A1 (DE)
Title: Spindle bearings for spinning frame - has base bearing elastic metal support to reduce noise
Inventor: STAHLECKER GERD
IPC: D01H7/10
Filed: 1990-10-26
Abstract: A ring spinning frame spindle has neck and foot bearings, and for the purpose of noise reduction, the foot bearing is separated from the bottom of the housing by a distance piece. Pref. the distance piece is constructed from an highly elastic material, and the base housing is cast iron of heavy construction. The contrast between the two metals improves the noise absorption, and prevents it passing through the housing to the spindle rail. ADVANTAGE - The noise is reduced, so that all packing at the neck is for alignment, improving the rigidity, with less wear and vibration and therefore again reducing noise.
Patent DE-4103190-A1 (DE)
Title: Tool for chamfering both ends of through holes - has tool bit pivoted out to cutting position by centrifugal force acting on eccentric mass at speed
Inventor: STOEWER GUENTER
IPC: B23B51/10
Filed: 1991-02-02
Abstract: The chamfering bit (2) is at the bottom end (6) of a rotatable shaft (1) which is eccentric to the axis of rotation of the tool housing (4). Secured to the top end of shaft (1) and on the same side as the chamfering bit is an eccentric mass (10). When the tool is rotated at speed, the mass swings out against the constraint of a spiral spring (11) to abut against a stop and hold the chamfering bit in the outward pointing cutting position. At zero or low speed the mass and chamfering bit swing to point inwards, so tat the tool can be passed through the hole to back chamfer the rear corner. USE/ADVANTAGE - Chamfering holes in armature flanges and other parts with inaccessible rear face. Simple, rigid and low-cost design.

Title: Building alarm system - has central unit to which are coupled two signal lines with series-connected sensor discriminators
Inventor: EJIRI MITSUHIRO
IPC: G08B25/00
Filed: 1991-02-14
Abstract: A pair of signal lines (l1, 2) are coupled to the alarm central unit (200). Along the lines are series-connected sensor discriminators (201a, 202a, 203a) for signal transmission traffic with the central unit. A signal, passed by the respective signal discriminator is received by the central unit over the signal lines for recognition of a sensor triggering an alarm. Pref. order priorities are associated with the sensor discriminator. The allocation of the order priorities may be carried out in conjunction with the series position of each sensor discriminator w.r.t. the central unit. A terminal sensor discriminator (203a) is typically coupled to the terminal circuit (204), over which the signal line cables are interconnected. ADVANTAGE - Facility for individual recognition of active sensor without increased installation expenditure.

Title: Fullerene prodn. - by evaporating and condensing carbon@ at 0.05-0.5 bar in oxygen-contg. gas extracting with solvent
Inventor: DORN FRIEDRICH-WILHLEM DIPL CH
IPC: C01B31/02
Filed: 1991-09-06
Abstract: Prodn. of a C60/C70 mixt. (fullerene) (I), comprises evaporating carbon at 0.05-0.5 bar, condensing the vapour on a cool surface to give a mixt. of (I) and carbon black, and extracting (I) with organic solvent. Evapn. and condensation are preformed in an oxygen-contg. gas i.e. CO, CO2, oxygen or a mixt. thereof, opt. with addn. of inert gas. USE/ADVANTAGE - The above gases are much cheaper than He which is normally used and their use enables a much higher evapn. rate from carbon electrodes for the same current density. (I) is useful as a starting material for new syntheses and materials. In an example, the process was performed in a metal vessel fitted with an EK 78 graphite (RTM) rod as cathode and an EK 86 graphite (RTM) rod as anode 2 mm. apart. The vessel was evacuated to 10 power (-5) bar, and then CO was passed through the system at 0.5 l/hr. at a constant pressure of 0.2 bar, while an arc was produced between the electrodes with I = 120 A (43 V) and maintained at 1-10 mm. by advancing the evaporating anode. The anode lost 104 mm. in 8.8 mins., corresp. to 5.93 g. graphite, and 4.33 g. carbon/fullerene mixt. (II) was collected from the water-cooled walls of the reactor, this mixt. contained 7.1% crude (I) as determined by exhaustive extn. with toluene and drying at 150 deg.C. With He instead of CO, the anode lost 105 mm. (6.53 g.) in 15 mins., and the yield was 3.28 g. (II) contg. 7.4 g. (I)

Title: False twister - has sprung support plate to move into two settings for left or right twist
Inventor: SCHMITT GUENTHER
IPC: D02G1/04
Filed: 1991-09-18
Abstract: The support plate to change the direction of a false twisting appts. is held at a central setting by the action of at lest two opposing springs. It is moved into the position for a left or right twist by sliding against the action of one spring and is then locked in place. Pref. the springs are concentric to each other, so that the inner spring acts as a draw spring and the outer spring is a pressure spring on a change-over, and both springs act independently. The inner draw spring is firmly anchored to the support plate by a spring holder and the other end freely moves in the holder with the draw spring holder. The outer pressure spring is firmly anchored in the holder through the spring holder and moves freely at the support plate through the spring holder. The spring action is central between the column and bolt. A sliding grip at the column is moved to lock the max. left and right twist setting, with two locking points to be engaged by a cylinder pin keyed to the column. ADVANTAGE - The assembly gives a simple and rapid change when the direction of twist has to be reversed at a false twister.

Title: Control circuit for AC=DC pulse width modulation converters - uses real and imaginary components of incoming 3-phase supply to generate control signals for PWM unit
Inventor: MIYAZAKI MASANORI
IPC: H02M7/219
Filed: 1992-03-13
Abstract: The voltage control circuit (7) produces a real reference current Ip1 based on the difference between the reference voltage V1 and the voltage across the smoothing capacitor (4) as derived by the voltage detection circuit (6). The current detector circuit uses the sinusoidal reference values (IR, IT) derived from the current detectors (12R, 12T) together with the phase reference (psiPS) obtained from the phase detector (8) to calculate real and imaginary current components (IP, IQ). These two signals are subtracted from the real reference current and used by the effective current control circuit (14) and the reactive current control circuit (15) to produce real and imaginary voltage reference signals ep1 and eo1 which are passed to the PWM control circuit (16). The latter combines these reference signals with the psiPS signal from the phase detection circuit to produce switching signals (SW) for the PWM converter. ADVANTAGE - DC to AC feedback control enables accurate governing of pulse width modulator.
