Patent SE-8000048-L (SE)
Inventor: MENZIES R
IPC: H02M7/527
Filed: 1980-01-03
Abstract: A self-commutated invertor is driven at the fundamental frequency, this frequency being variable and it being possible to use it, for example, to control the rotation speed of a motor. In this case, the harmonic content at specific phase angles ( alpha 1,  alpha 2,  alpha 3,  alpha 4) can be reduced by means of additional commutations, but a minimum time interval ( tau t), which corresponds to an interval angle ( DELTA  alpha ) which is proportional to the fundamental (f1) must in this case be maintained between successive commutations. The object is to create a control method which is suitable for suppressing harmonics over wide fundamental ranges. The solution provides an automatic changeover in the number of additional commutations (M = 1, 2, 3 ...) as a function of at least one limiting value of the control fundamental (f1) in the opposite sense to the change in said fundamental. <IMAGE>

Abstract: An improved electrolyte absorber for alkaline battery cells has low resistance to electrolyte ion transfer and can hold alkaline electrolyte in contact with an electrode during chemical reactions of the cell. The absorber is formed by depositing an improved wetting compositions to a polyolefin substrate. The substrate, preferably, is a fibrous and porous melt blown thermoplastic web made up of a plurality of physically entangled microfibers, resistant to strong alkali and oxidation. The wetting composition which is deposited over and adhered to external surfaces of said microfibers is comprised of a substantially homogeneous admixture of a polymeric binder, inert hydrophilic filler particles and a phosphate ester wetting agent. Portions of the filler particles in the composition protrude through the binder and are exposed in random distribution. When the absorber is immersed in electrolyte, the phosphate ester wetting agent reacts with the electrolyte to lower the surface tension thereof. The lowered surface tension permits the reacted electrolyte to rapidly wet the exposed filler particles.

Abstract: The invention concerns an apparatus for determining the degree of variation of a feature in a region of an image that is divided into discrete picture elements, the feature being represented by complex valued signals, one for each picture element, the signal phase representing the feature class and the signal magnitude representing the certainty in the feature assertion. The apparatus includes a unit (3) for providing the complex valued signals (8) within the region and complex valued multiplication factor signals (9) corresponding to the complex valued signals. In a first summation unit (4), a first sum signal is generated by the magnitude products of the signals (8) and corresponding multiplication factor signals (9), and a second sum signal is generated by the complex valued scalar products of the signals (8) and corresponding complex conjugate of the multiplication factor signals. In a second summation unit (5), a third sum signal is generated by the signals (8) that are weighted with the magnitude of corresponding multiplication factor signals (9), and a fourth sum signal is generated by the complex conjugate of the multiplication factor signals (9) weighted with a magnitude of corresponding signals (8). A norming unit (6) is provided for norming the output signals from the summation units in a predetermined way (FIG. 2).

Abstract: In a hydraulically damped resilient mounting of the type where an elastomeric spring 2 and a diaphragm 4 define two liquid-filled chamber 8, 9 which communicate via a throttle 17, a chamber 10 on the other side of the diaphragm (which would normally be at atmospheric pressure) can be subjected to a reduced pressure when desired. This causes the diaphragm 4 to deflect to the dotted line position which induces cavitation in the liquid. This renders the throttle 17 and therefore the hydraulic damper ineffective, thus removing a source of undesirable noise. When the mounting is used to mount a vehicle engine, vacuum is supplied from the manifold either selectively or automatically in response to sensed parameters. <IMAGE>

Abstract: PCT No. PCT/SE87/00582 Sec. 371 Date Jun. 21, 1988 Sec. 102(e) Date Jun. 21, 1988 PCT Filed Dec. 8, 1987 PCT Pub. No. WO88/04502 PCT Pub. Date Jun. 16, 1988.The invention relates to an apparatus for powering a loudspeaker amplifier (5) in a telephone set fed with a line current (ILO) from a telephone line (3). An incoming speech signal (S) is amplified (8) and sent to a loudspeaker (4) via the amplifier (5), which is powered via its feed connections (19, 20) from a reservoir capacitor (6). By the capacitor feed there are avoided variations in the line current (ILO) on amplification of the speech signal (S). The capacitor is recharged with the aid of the speech circuit (13), which has an amplifier means (16, 17) sensing a line voltage (UO) via a voltage sensing circuit (18). The amplifier means (16, 17) steers the line current (ILO) to a constant value responsive to the line voltage (UO) by sending a current (16) to the line (3) via a resistor (R1), thus keeping constant a current (14) through the resistor (R1), this current being sensed by the amplifier means. The reservoir capacitor (6) is connected via a controllable current generator (22) to the resistor (R1) and a circuit (24), which senses the voltage across the resistor (R1) and controls the generator (22). The reservoir capacitor (6) is charged by a current (15) through the current generator (22) and the amplifier means (16, 17) controls its output current (16) such that the current (14=15+16) through the resistor (R1) is kept constant. The apparatus utilizes the existing speech circuit (13) to keep the line current (ILO) constant at the power supply.

Abstract: A drive mechanism for a motor vehicle windshield wiper device has a crank which is driven in a rotating manner and produces a pivoting movement of a windshield wiper via a drive rod. If the movement of the windshield wiper is obstructed by a snow wedge building up in the wiper socket, the drive mechanism provides for an obstruction evading movement of the drive rod in such a way that the crank can fully rotate unimpeded. In order to obtain a low loading of the drive rod and its joints in the event of obstruction of the windshield wiper and to obtain a uniform wiping zone in normal wiping operation, the novel drive mechanism for the drive rod is firmly coupled to the crank and a lost motion drive means is arranged on the wiper shaft.
