Patent DE-3100953-A1 (DE)
Title: Two-armed intake pipe bend for suction pumps
Inventor: BURCHARDT GERHARD
IPC: F04D29/42
Filed: 1981-01-14
Abstract: Upstream of suction pumps, which convey effluents carrying various solids, a disc-shaped blocking mechanism is arranged, which retains the coarse particles and which, owing to the defined annular blocking gap formed, produces a self-cleaning effect, owing to which the hitherto required daily cleaning is dispensed with. The intake pipe bend which assists in securing the blocking mechanism is constructed with two arms on its inlet side, giving rise, in conjunction with the continuous partition, to an antirotation effect. This effectively prevents the otherwise routine formation of plugs from textiles or other fibrous materials and thus provides for blockage-free pump operation.

Title: Sodium-cooled nuclear reactor
Inventor: HAMMERS HEINZ-WILHELM ING GRAD
IPC: G21C1/32
Filed: 1981-04-21
Abstract: The invention relates to a sodium-cooled nuclear reactor whose reactor vessel contains the primary coolant circuits, a shield surrounding the reactor core and a primary/secondary heat exchanger, in particular a fast breeder reactor according to the modular principle. In order to implement this modular principle, it is proposed to arrange electromagnetic coolant circulating pumps outside the reactor vessel, the heat exchanger being provided in an annular housing above the pumps. This housing has at its upper end a plurality of openings to the space above the reactor core, and further, smaller openings at mid level to the same space, and is connected at its lower end to an annular space between the vessel wall and reactor core. It is also proposed, as the most favourable embodiment, to arrange the annular electromagnetic pumps concentrically around the reactor vessel, an annular channel being present on the inside of the reactor vessel. In this way, the sodium-cooled nuclear reactor is suitable as a module for an arrangement having a relatively large number of such elements. <IMAGE>

Patent DE-3131182-A1 (DE)
Title: Door-handle connection with a handle spindle
IPC: E05B3/10
Filed: 1981-08-06
Abstract: In a door-handle connection with a handle spindle which consists of two longitudinal halves having rectangular cross-sectional shapes and engages into internal squares of the neck of door handles and which passes through the internal square of a lock follower, the longitudinal halves are mutually displaced, by means of a pressure screw tightenable against the handle spindle, until they bear firmly with their diverging sides in the internal squares of the door handles and in the internal square of the lock follower. Since the pressure screw works into the material of the handle spindle in the course of time when the handle spindle is retensioned, retensioning does not have a permanent effect. In order to overcome this disadvantage, one longitudinal half of the handle spindle, which is connected operatively to the pressure screw provided with a conical tip, possesses on one outer face, in front of each end, in a respective recess, a flattening which forms a right angle with the side with which the longitudinal half faces the other longitudinal half, and on which, during tightening, the pressure screw engages with the envelope of the conical tip.

Patent DE-3137546-A1 (DE)
Title: Arrangement for determining and keeping constant the weight per metre of an extruded product
Inventor: FREDE WILHELM E
IPC: G01G11/18
Filed: 1981-09-22
Abstract: The invention relates to an arrangement for determining and keeping constant the weight per metre of an extruded product. A known apparatus has a first weighing device, recording the mass flow of the initial material, and a feed channel as a connection to the extruder draw-in. The speed of a drive drawing off the product from the extruder can be controlled by a control circuit. According to the invention, the accuracy and speed of the compensation of fluctuations in the weight per metre are to be achieved in that the feed channel is designed as an overflow channel, in that the particular initial material flowing over is fed to a second weighing device, and in that a computer forms an influencing quantity which is fed to the control circuit and which corresponds to the difference between the total weight of the mass flow and the weight of the part flow which has overflowed.

Title: Pump for the conveying of liquids, particularly of liquid pulps
Inventor: HORNOK SANDOR DIPL ING
IPC: F04B7/02
Filed: 1981-09-25
Abstract: For the conveying of liquids, particularly of liquid pulps where different liquids have simultaneously to be pumped from a plurality of inlet chambers into a common working chamber or where liquid is to be conveyed from a common working chamber into different pressure chambers, a pump is used in which the separate inlet chambers or pressure chambers are connected by way of automatic valves to the common working chamber of the pump. The valves of the separate inlet chambers or pressure chambers are therefore forcibly connected to one another by means of a movement transmission mechanism. This forcible connection may be of hydraulic or purely mechanical design, for example. In this way, simultaneous working of the valves is possible so that a reliable pump is ensured by relatively simple means. <IMAGE>

Title: Process and device for feeding yarn to the stitch forming system of a knitting machine
Inventor: GEORGEVIC IPPOLIT CITOVIC
IPC: D04B15/48
Filed: 1981-11-27
Abstract: The process and the device are used in circular knitting machines for the production of piece goods or knitted fabrics. Turns (B) are formed from a yarn (A) and loop round a yarn-feed drum (3), interacting with a driving belt (2), and a bar (4) mounted overhung. At least part of the turns have a possibility of storing themselves both under the belt (2) and outside the latter. During the time when the yarn turns remain outside the belt (2), the yarn tension is reduced by bringing these yarn turns into contact with an additional yarn-feed drum (5) which rotates at a speed higher than the speed of the main yarn-feed drum (3). This makes it possible to check either the yarn tension or the yarn-feed speed at a predetermined moment during the knitting of a product. <IMAGE>

Title: Circuit arrangement for setting up charge-free calls for the calling subscriber
Inventor: REINHOLD ANDREAS
IPC: H04M15/08
Filed: 1981-12-14
Abstract: The facility for setting up charge-free calls for the calling subscriber to predefined subscriber connections in a telephone switching system, it being the case that translation into the telephone number of the allocated subscriber connection is effected by dialling a special service number and a subsequently dialled number identifying the predefined subscriber connections and that, following the successful through-connection of the call, charges are recorded and debited in each case to the predefined called subscriber connection, is comprised in that a telephone PABX system connected to the local exchange concerned is reached by dialling the special service number, in which PABX system the conversion also takes place and which also takes over the further call set-up to the predefined called subscriber connection. With the aid of announcement devices, operator positions and subscriber connections on the telephone PABX system, the calling subscriber obtains appropriate support which may comprise the transfer of announcement texts or information or the input of the telephone number by the operator position. If the call set-up initiated by the telephone PABX system to the predefined called subscriber does not reach the destination, the calling subscriber is automatically connected to an operator position or a predefined subscriber connection, the owner of the latter connection being identical to those of the predefined called subscriber connection. <IMAGE>

Title: Photographic cassette camera having a control device for a cassette-side exposure-opening cover element
Inventor: BETHMANN HEINZ G
IPC: G03B17/02
Filed: 1982-02-16
Abstract: Engaging in a cover element of a film cassette which covers a cassette-side exposure opening in a light-tight fashion is a driver that is movably arranged on the camera side. The driver is a component of a camera-side control device for the cassette-side cover element. The cover element control device is coupled to a rear cover locking device in such a way that when the rear cover is unlocked for the purpose of cassette removal the cassette-side cover element is firstly moved into its closed position. Not until the cover element has reached its closed position does the unlocking of the rear cover become effective. A resilient coupling element moves the cover element control device in a force-fitting fashion up to a position assigned to the cover element closed position, and by means of resilient deflection compensates for the further movement of the rear cover locking means as far as unlocking of the rear cover. The entire device is latched in the unlocked position of the rear cover, so that the cover element driver remains in a fixed initial position. This latching is automatically cancelled upon closure of the rear cover. None of the figures are to be published.
