Title: Automatic liq. filter having intermittently moving filter belt - ascending from tank to remove filtered solids eliminates vacuum drum difficulties
Inventor: JAREMUS BOUBENE
IPC: B01D35/027
Filed: 1980-05-21
Abstract: Filter comprises a guide system by which a continuous a band of filter material is drawn from a storage roll, guided downwards into a tank and then up again round the guides to leave at the top; the filter material is intermittently moved forwards by a stepping drive and the filtrate is extracted from a chamber connected to the suction side of a pump by a pump intake. This filter chamber has a perforated wall to support the ascending side of the filter belt. The pump has a valve system to enable the suction pressure to be intermittently relieved so that there is no pressure difference across the belt and perforated plate and the belt is released from the perforated plate. Preferably, the perforated zone of the plate is narrower that the total width of the filter material so that a zone free of dirt is produced at each edge of the filter belt; the stepping drive mechanism comprises a roller around which the belt passes and a pair of slender counter-rolls acting on the opposite side of the filter belt only in these clean edge regions. The difficulties of vacuum drums do not arise. There are no special sealing problems. A high throughput of liq. and efficient filtering are achieved with an economical plant. The filter band is accommodated in a very small space at the end of the tank.

Title: Electric resistance heating jig for heat treatment of tubes - has fixed and mobile arms with tongs on respective opposite sides of trolley
Inventor: BODYAKO MICHAIL NIKOLAEVIC
IPC: C21D1/40
Filed: 1980-07-17
Abstract: A housing has a drive unit for moving a trolley vertically along guides. On one side of the trolley is a fixed arm (I) carrying tong arms, and a pivot mounting for a lever actuated by a work cylinder, so a rod can force the tong arms apart. On the other side of the trolley is a mobile arm (II), which carries the same devices as arm (I). But arm (II) can be moved to permit the tongs to clamp tubes with different lengths. A tube is clamped in the jig, and electricity is fed through the tong arms to heat the tube to a desired temp. The tube is then cooled, esp. by lowering the trolley so the tube enters a tank contg. a quenching liq. Used for thin walled tubes, e.g. with max. outside dia. of 50 mm, where the tube is securely clamped so it does not distort during quenching.

Title: Indicating circuit for telephone system - indicates subscriber loop closure as result of call by using two voltage dividers and comparator
Inventor: KOPETZKY HORST
IPC: H04M19/02
Filed: 1980-09-29
Abstract: The indicating circuit has a supply resistor (Rs2) in the grounded wire (b) of the telephone line (AL) serving the call-current circuit and the supply-current circuit. The voltage drop across this resistor is passed to a comparator (K) via two voltage dividers (R1,R2,R3 and R4, C, R5, R6,R3). The first divider contains a series capacitor (C). The comparator produces an output when a call occurs whilst the subscriber loop is open and a second output when a call occurs whilst the loop is closed. The advantage lies in fast response.

Title: Electroacoustic signalling unit
Inventor: ELY HELMUT ING GRAD
IPC: G10K1/064
Filed: 1981-01-29
Abstract: The invention relates to an electroacoustic signalling unit having three sounding members which are suspended oscillating loosely on holders of a base part and between which there are arranged two electromagnetic exciting systems having plungers which can move transversely relative to the sounding members. Whereas, e.g., DE-A 2,716,427 provides as sounding members three plates of which the middle one has a cutout for the passage of a plunger, the invention exhibits a solution by means of which it is possible in a manner which likewise saves space to use two hammers to strike three sounding members which do not require any cutout, so that it is possible to use tubes as sounding members. The invention achieves this essentially by arranging the exciting systems (21, 23, 25 and 22, 24, 25) tilted with respect to one another in such a way that the movement tracks of their plungers (29) - at least in a view onto the arrangement in the direction of the longitudinal axis (30) of one of the sounding members (12) - is situated approximately on the longitudinal central axis (30) or central plane of this sounding member (12), whereas the two other sounding members (11, 13) are arranged, with reference to the base part (17), right next to one another. <IMAGE>
