Patent EP-0013175-A2 (EP)
Inventor: HIRAGA MASAHARU
IPC: F16C35/06
Filed: 1979-12-24
Abstract: A device with an electromagnetic clutch includes a tubular member of steel which is secured to, and cantilever supported by, a flanged member secured to a housing of the device. A pulley having magnetic pole faces is rotatably mounted on the tubular member by one or more bearings. A drive shaft of the device extends out of the housing and through the tubular member, and supports a magnetic armature on its outwardly extending end. An electromagnet associating with the pulley is fixedly supported on the flanged member, to supplythe magnetic attraction force for attracting the armature plate to the pulley. Since the wall of the tubular member is thin, the outer diameter of the clutch can be reduced without degrading the transmission of rotational force. Also, a shaft seal assembly can be mounted on the drive shaft within the tubular member. Furthermore, the inner ring of the bearing is held between the flange member and a retainer ring fitted onto the tubular member and is therefore prevented from axial movement. In order to prevent the inner ring from rotating, the inner ring is locked to the flange member by cooperation between projections and mating depressions formed thereto. Thus, the assembling operation of the electromagnetic clutch is simplified.

Abstract: Adsorbed calcium is selectively removed from cation exchange resins in the presence of adsorbed magnesium by eluting the resin with aqueous sulfuric acid saturated with CaSO 4  and undersaturated with MgS0 4  to obtain a solution supersaturated with CaSO 4  from wich the CaSO 4  can be readily precipitated. The magnesium is subsequently removed from the resin by eluting with aqueous sulfuric acid, such as 20-70% H 2 SO 4 . The method is advantageously used in the regeneration of cation exchange resins, such as the loaded resins used for treatment of phosphate rock-derived phosphoric acid.

Abstract: Private telephone exchanges with traffic to the public telephone network must be able to receive dialling prompting signals sent out by the latter. Such signals can occur at any place within the sequence of digits country specifically and in dependence on the exchange number in each case dialled by an extension user. The method allows such a dialling prompting signal to be automatically detected in a private telephone exchange, with simultaneous marking of the place within the sequence of dial digits where the signal has occurred. For this purpose a timing section is tripped in each case at the beginning of the sending-out of a dial digit which is within a predetermined range of the dial digits necessary for setting up an exchange connection and, at the same time, a receiver (WTE) for dialling prompting signals, which is arranged at the link between the dialling subscriber station (TN) and the exchange circuit (AS), is activated with each tripping of the timing section. With each tripping of the timing section, an information on the number of digits dialled since the beginning of the predetermined range is stored and when a dialling prompting signal is detected by the receiver (WTE), the timing section is reset, the receiver (WTE) is made inoperative and a marking "waiting for a dialling prompting signal" is stored at the appropriate place within the sequence of dial digits in a store (WSP) accepting the dialled digits. For the purpose of automatic redialling, the content of the store (WSP) can be supplied to an automatic dialler which is thus capable of waiting for a dialling prompting signal occurring between the individual digits, if required. <IMAGE>

Abstract: A method is described for reducing the amount of data that must be transmitted over a telecommunications link in order to generate an acceptable video image of a bilevel document at a remote monitor. Document data is captured at 8 bits/pel with a conventional video freeze-frame system. The captured data is normalized to eliminate variations due to camera settings, room lighting levels and the like. A table lookup process is used to threshold the data to 4 bits/pel with different single pel values being assigned to pels having normalized normalized values above or below set threshold values. The number of intermediate gray scale ranges is reduced. The thresholding process provides log strings of constant pel values while suppressing small nonuniformities in the document's background. The resultant data is optimized for run length compression and the image quality is improved. At the receiver, a second table lookup process is used to define playback values. To provide optimum contrast between characters and background, the table lookup values at the receiver may be different from those used in the compression process.

Abstract: The device is intended, in particular, for safety helmets for people travelling together on one motorbike. It has for each helmet a mouthpiece (4, 4') and an earpiece (2, 2') and an acoustic lead (6, 6', 7, 7'), which connects the mouthpiece of the one helmet to the earpiece of the other helmet, for pneumatic sound transfer. The earpiece consists of a soft, elastically deformable material and is to be arranged without attachment means between the inside wall of the helmet and the head of the wearer. This is made possible by the fact that the height of the earpiece (2, 2') perpendicular to its base surface is greater than the distance between the inner wall of the helmet and the head of the helmet wearer. A tube (3, 3') supporting the mouthpiece (4, 4') and the acoustic leads (6, 6', 7, 7') for the connection to the other participant are attached to the earpiece (2, 2'). <IMAGE>

Abstract: A movable grate (50) is mounted on an upright pipe (36) is disposed within and spaced above the bottom of an upright vessel (12,14) of a gasifier. A layer (54) of loose, high heat resistant, ball-like elements is established on the grate (50). Biomass is continuously charged into the vessel (12, 14) above the grate (50) and combusted so as to form a char-bed of biomass immediately above the layer (54). Combustion-supporting gas is introduced into the char-bed and drawn downwardly through the char-bed, the layer (54) and the grate (50). The gas generated thereby is withdrawn from the vessel (12, 14) below the grate (50) by means of a fan (72). The grate (50) is moved so as to move the individual elements of the layer (54) and effect gravitational filtering of char-coal particles from the char-bed. The char-bed is agitated and combustion-supporting gas is introduced into the char-bed by the pipe (36) and the tubular branches (62, 64, 66).
