Title: Hydraulics control magnet having a pressure-tight inner tube
Inventor: KOERSGEN HEINZ-NORBERT ING GRA
IPC: H01F7/16
Filed: 1982-05-10
Abstract: The invention relates to the sealing of pressure-tight inner tubes for guiding the magnet armature of hydraulics control magnets with and without manual emergency operation. Known seals of inner tubes have disadvantages which are caused by problems related to production engineering and hydraulics. An economical disadvantage of known configurations is that unsealed inner tubes cannot be identified until final testing of the completely manufactured control magnets. Sealing defects can then be rectified only by dismantling the complete control magnet, the costly magnet housing frequently no longer being usable. In the case of hydraulics control magnets according to the invention, the technical and economical disadvantages are avoided and additional advantages are achieved essentially by incorporating a sealing core into the end of the inner tube opposite the pole core, as is shown in the drawing. The internal sealing (which is achieved by means of an O-ring) of the inner tube results in the smallest possible reaction forces on the attachment bolts of the control magnet. The sealing core can be manufactured without problems and its dimensional conformity can easily be measured and reproduced. The unit, which is shown in Figure 2, can be assembled separately, consists of the pole core, inner tube, magnet armature and sealing core, and has manual emergency operation can intrinsically be tested hydraulically without the magnet coil and the magnet housing being present. At the same time economical storage of this unit is achieved irrespective of the electrical data of the magnet coil. The economical production of the manual emergency operation and its support in the magnet housing are advantages. <IMAGE>

Title: Apparatus for feeding wood, in particular roundwood, to sawmill machines
Inventor: LOEBNER ANDREAS DIPL ING
IPC: B27B31/06
Filed: 1982-07-28
Abstract: An apparatus is proposed, which serves for feeding in particular roundwood to sawmill machines and has a driven endless chain transporter on which the wood rests, and a plurality of clamping-element pairs arranged along the endless chain transporter at intervals and acting laterally on the wood in order to centre the latter on the processing machine. In the known apparatuses, the clamping-element pairs are fixedly arranged, and the wood moves relative to them, with the result that it is not reliably secured even against rotation. Moreover, it is not possible to break up the wood continuously. These deficiencies are eliminated with the invention by the fact that a clamping-element pair (5) is arranged on a rail-borne lockable carriage (8) with its own travelling gear and is freely movable, in terms of height, on the latter with clamping elements (5a, 5b) coupled for positive comovement in the vertical direction.

Title: Process for the removal of electrolytically dissociated salts present in small amounts from concentrated solutions of other dissociated salts
Inventor: VAJNA SANDOR DIPL ING CHEM DR
IPC: B01J47/00
Filed: 1982-09-25
Abstract: According to the invention, electrolytically dissociated salts present in small amounts are removed from solutions which contain other electrolytically dissociated salts at high concentration. For this purpose, the solution is passed to a prepared exchanger bed, whose counterions have previously been equilibrated with those of the solution and the bed washed out with water. During the feeding of this solution, the bed takes up counterions and co-ions of both groups as a result of absorption, the quantities taken up being established in accordance with the Donnan equilibrium. According to the invention a second solution is now passed through the bed, which solution only contains those counterions which are contained in the first solution at high concentration, and the co-ions. This solution removes from the exchanger bed the quantity of the other counterions taken up by it. Subsequently, water is applied to the bed, which displaces the second solution from the bed, which solution only contains those ions which were present in the first solution at high concentration. Part of this outflow is stored and used again in the next process cycle and another part is passed out as the product of the process.

Title: Digital frequency phase comparator
Inventor: BURGER ERICH DIPL ING
IPC: H04L7/033
Filed: 1982-11-29
Abstract: The present invention is based on a frequency-sensitive phase comparator (KP) proposed in the main patent 3130156.8, which is essentially constructed with flip-flops (K1, K2, K3) and is of the type suitable for phase-locked loops at the receiving end of digital data transmission systems for synchronisation of the receiving-end clock with the bit rate of the incoming data signal (DS). In a further development of this digital frequency/phase comparator (KP) for the synchronisation of a pulse string (f1) to be adjusted with the bit rate of a data signal (DS) having a random character, it is proposed to derive the reference pulse string (f2) from the data signal (DS) via a pulse transformer (PW) which generates the reference pulse string from the consecutive pulse edges of the binary data signal in the form of a unipolar string of short pulses. <IMAGE>

Title: Pressurising and return gas pipe for filling valves in counter- pressure filling machines
Inventor: HINZE WERNER
IPC: B67C3/06
Filed: 1982-12-02
Abstract: A rapidly releasable fastening for pressurising and return gas pipes for filling valves in counterpressure filling machines is to be produced which can also take a relatively large axial load, especially when a purging tank attached to these pipes is used, and it is to be ensured that the pipe is protected against twisting, in addition. The invention solves this problem, as shown in Figure 1, by giving the valve body (1) and/or its location hole (2) two arresting elements (6, 7) at different levels (3, 4) from one another, which arresting elements place the gas pipe (8) in a release position or in an arresting position when it is turned. One (3) of these levels is formed in the location hole (2) from two bolts (7) which are perpendicular to the axis of the hole and which match a recess (9, 10) in the gas pipe (8) which is in the shape of a partial groove and the second level (4) comprises a semicircular split washer (11), the ends (12, 13) of which engage in a second recess (16, 17) in the gas pipe (8). <IMAGE>

Title: Method for determining the delivery characteristics of injection pumps for internal combustion engines and device for implementing the method
Inventor: URLAUB ALFRED PROF DR ING
IPC: F02M65/00
Filed: 1982-12-07
Abstract: In order to improve the measuring accuracy and in particular to improve the degree of reproducibility of the measured value when determining, adjusting and monitoring the delivery quantities of injection pumps, the pump counterpressure necessary for a delivery measurement is produced by pressure reservoir. At the same time the test fluid delivered by the pump, is led, for example, into a pressure vessel filled solely with this test fluid and the increase in pressure which has occurred in the vessel as a result after a certain number of pump working cycles is determined as a measure of the working cycle delivery quantity.

Title: Drive device for roller skates
Inventor: MASHAIKHY HASSAN
IPC: A63C17/12
Filed: 1982-12-08
Abstract: The invention relates to a drive device for roller skates, consisting of a shell and a piston, in which connections to turbines are arranged. The previously customary roller skates do not make sufficient use of the person's weight. It is thus too difficult to travel obliquely upwards. The object of the invention is to construct the roller skate drive in such a way that ascending slopes can easily be overcome by utilising a person's weight. To achieve this object, provision is made for the piston to be inserted in the housing. The axle of the rollers is arranged centrally in the turbine and each housing has stoppers so that the pistons cannot come out of the housing. Mounted on each piston is a rod, to which the skates are attached. The axle of the rollers is fixed to the housing by the adjusting screws.

IPC: B30B11/22
Filed: 1983-02-23
Abstract: Briquetting machine with partly cylindrical press jaws (8, 10); method and device for regulating the compacting pressure. The aim of the present invention is to design a briquetting press such that the compacting pressure may be rapidly and automatically regulated as a function of the properties of the material to be compacted so as to eliminate the press overloads and to obtain constant quality briquettes. To this effect, the press jaws (8, 10) are adjustable through a controllable unit exerting wedge forces. Said unit is provided with wedge surfaces (44, 46) formed on the press jaws, on which pressure rolls (48, 50) arranged in a moving frame (52) are moved. In order to regulate the compacting pressure, the load of the reciprocating press motor (80) is compared with a threshold value. When the load deviates from the threshold value, the compacting pressure of the press jaws (8, 10) and/or the amount of supplied material is modified so as to regulate the reciprocating press motor (80) to the threshold load.

Title: Press-in device for rotor shafts of electrical machines
Inventor: WEBER KLAUS DIPL ING
IPC: F16D7/00
Filed: 1983-03-31
Abstract: When pressing a shaft (a) firmly clamped in the press ram of a press into the hub (b) of the rotor of an electrical machine, the effects of positional and manufacturing tolerances of the rotor are to be compensated without exerting bending moments on the shaft (a). For this purpose, a supporting sleeve (c) which supports the hub of the rotor is mounted via two floating plates (d1, d2) on a guide plate (f). A first needle-roller flat track (e1) between the two floating plates and a second needle-roller flat track (e2), offset by 90 DEG relative to the first, between the lower floating plate and the guide plate (f) permit a horizontal motion of the supporting sleeve in two directions. By virtue of the fact that the guide plate (f) rests on a plurality of hydraulic pistons (g) connected via a ring conduit to form a hydraulic system, an additional cardanic swivelling movement of the supporting sleeve (c) is possible. <IMAGE>

Abstract: In the case of a semiconductor memory having storage elements which are arranged in rows and columns and are selectable with the aid of an address, the intention is for it to be possible to read or write information row by row or column by column. For this purpose, each storage element (SE) has a storage member, for example a flip-flop, which is connected via a first switching member (T5, T6), for example a selection transistor, to a first terminal (QH, /QH) of the storage element and via a second switching member (T7, T8) to a second terminal (QV, /QV) of the storage element. The first terminals (QH) of the storage elements (SE) are connected row by row in each case to a row-bit line, the second terminals (QV) of the storage elements are connected column by column in each case to a column-bit line. The column-bit lines and the row-bit lines lead in each case to write-read amplifier circuits. The connection of the storage members (SG) to the first or second terminal (QH, QV) of the assigned storage element takes place in dependence on a selection signal and an address, which are fed to a row-decoder circuit or column-decoder circuit, respectively. The row-decoder circuit or column-decoder circuit selects from address and selection signal either a row-word line (WLH) or a column-word line (WLV), via which the selection transistors (T5, T6 and T7, T8, respectively) are controlled in such a way as to make them conductive. As a result, the inputs/outputs (K1, K2) of the storage member (SG) ... either with the first terminals ... Original abstract incomplete. <IMAGE>

Title: Process and apparatus for the production of defined humidity in a carrier gas
Inventor: TITTIZER GABRIEL DIPL ING
IPC: B01D53/26
Filed: 1983-04-27
Abstract: An apparatus is proposed according to the present invention for the production of defined humidity in a carrier gas. It makes possible a continuous operation with higher accuracy and can be quickly set to different concentrations. For this purpose a humidified carrier gas is conducted by means of a cooling coil (5) through a cooling bath in which the excess moisture freezes out until the saturation pressure corresponding to the temperature is reached. The mixture is then heated up again in a heating bath (22) and passed to its destination. As short as possible a transition piece (7) between the cooling bath and the heating bath is decisive for the accuracy of the equipment. Moreover, the transition piece (7) should be as thin-walled as possible. In this manner, a displacement of the ice boundary is reduced to a minimum in the event of operating changes, which is of advantage for the setting time and accuracy. <IMAGE>
