Patent DE-3414483-A1 (DE)
Title: Fastening for a vibration unit held on a leader for driving and extracting trench sheet piles or the like
Inventor: WALTER LUDWIG
IPC: E02D13/04
Filed: 1984-04-17
Abstract: In the hitherto known fastenings for vibration units, these vibration units are on the one hand suspended via rubber cushions (facing one another in pairs) on the associated leader slide in such a way as to be movable in the vibration direction and on the other hand are supported on lateral-guide elements which are designed as sliding bearings. However, this type of lateral guidance of the vibration unit is economically unsatisfactory and unsatisfactory from the point of view of noise generation; it leads to a considerable loss of vibration energy in particular in the event of a change in position of the vibration unit relative to the leader slide. To remove the disadvantages mentioned, it is proposed that the lateral guidance of the vibration unit (1) also be carried out via interacting pairs of rubber cushions, the longitudinal axes (14', 15' or 16', 17') of the rubber cushions (14 to 17) of in each case two rubber-cushion pairs (14, 15 or 16, 17) lying in a plane (18) transversely to the vibration direction (double arrow 8), and the longitudinal axes of the rubber cushions of each rubber-cushion pair being inclined symmetrically with regard to a parallel plane (18') to the travel plane of the leader slide (2), and in fact preferably at an angle (a) of 90 DEG . <IMAGE>

Title: Process and device for dividing a plasticated plastics strand emerging from an orifice
Inventor: WEICHENRIEDER ERICH
IPC: B29C48/03
Filed: 1984-05-04
Abstract: For dividing a plasticated plastics strand, in particular obtained from contaminated plastics wastes, emerging from an orifice, the plastic is forced into a metering chamber and displaces an adjustable wall element of the metering chamber against a constant counter force. When a predetermined extent of the displacement of this wall element is registered, the strand is cut, the stream of plastic to the metering device is interrupted and the plastic contained in the metering chamber is discharged.

Title: Method for recording image representations in accordance with analog image information by means of a dot matrix printing mechanism
Inventor: BARTELS JUERGEN DIPL ING
IPC: H04N1/405
Filed: 1984-08-09
Abstract: To be able to record image representations, which are transmitted by analog signals obtained during the line-by-line scanning of an original to an output device, by means of a dot matrix printing mechanism, the analog signal is compared with a threshold value. With the image line which can be generated by the dot matrix printing mechanism being subdivided into n matrix dots, the comparison value is switched through n times to the printing mechanism, pixels being recorded or not recorded depending on the position of the analog signal compared with the threshold value.

Patent DE-3433624-A1 (DE)
Inventor: LAUTENBACH HORST
IPC: H01H9/38
Filed: 1984-09-13
Abstract: The switch has one or several stationary contacts (1, 2) and moving contacts (3 and 4), which make contact with one another in pairs, as well as two triggering devices (13, 14) which operate on the moving contacts (3, 4) and of which the first automatically cuts off the contacts when a short-circuit current occurs and the second when an overcurrent occurs. Furthermore, a switching-on device (15) is provided on the moving contacts (3, 4) which can be operated at will. In at least one contact pair (1-4) either the stationary contact (1, 2) or the moving contact is made of a contact material and, in an adjacent region (5) thereto, of a composite material which has arc-quenching properties. The moving contacts (3, 4) are operated in such a way that the closing of the switch can take place only above the coverage of the contact areas and the passage of a continuous current only below the coverage of the contact areas, which do not consist of the composite material, whereas the opening is effected in the case of short-circuit triggering by the separation of one region (5) consisting of the material of a first contact (1, 2) from the second contact (3, 4) of a pair of contacts.

Title: Circuit arrangement for operating a DC-braked AC motor
Inventor: SCHOLZ HORST DIPL ING
IPC: H02P3/24
Filed: 1984-11-07
Abstract: A DC-braked AC motor is connected to a supplying network (RYB) in driving operation via first contacts (1, 2) of a contactor which is controlled via a coil (S2). In braking operation, the AC motor (M) is connected in a DC braking circuit via a second contact (4), which switches in the opposite sense to the first contacts (1, 2) of the contactor, which DC braking circuit has a braking thyristor (Th1), which can be triggered by a first triggering device (TA), and a freewheeling diode (D1). In order to change over from braking operation to driving operation of the AC motor without any arc, the coil (S2) of the contactor is connected in series with a switching-on push switch (S3), a further thyristor (Th2), which can be triggered by a second triggering device (TV), and a diode (D2). Closing the switching-on push switch (S3) applies a voltage to the two triggering devices (TA, TV). In the case of the first triggering device (TA), this voltage blocks the emission of triggering pulses to the braking thyristor (Th1) and, in the case of the second triggering device (TV), it causes delayed emission of triggering pulses to the further thyristor (Th2). The circuit arrangement can be used universally in the case of DC-braked AC motors, particularly in semi-professional wood processing. <IMAGE>

Patent DE-3504851-A1 (DE)
Title: Conveying system with circulating supports
Inventor: BEYHL EBERHARD DIPL ING
IPC: B65G1/127
Filed: 1985-02-13
Abstract: The conveying system with circulating supports is a movement mechanism, by means of which appropriately constructed supports, in which storage goods, such as filing cabinets of all kinds or easily portable articles of all kinds can be accommodated are moved from one point to another by circulation. A guiding and supporting system is essentially necessary to achieve this. The guiding system comprises an endless guiding path with two straight sections and two semicircular curves and a three-roll guiding trolley which runs via the guiding path and is rotatably mounted in a control lever. The supporting system comprises, in relation to one side, two chain wheels, round which runs an endless support chain. Supporting arms on which the supports are fastened are suspended on the support chain. The supporting arms have three supporting rollers which run on straight sections for stabilisation via supporting rails. At the deflection points, supporting bolts in the chain wheel take over the task of stabilising the supporting arms. The supporting bolt of the support is mounted in the supporting arm. The control lever is rigidly connected to the supporting bolt and is the connection to the guiding system, which keeps the support vertical during deflection. The system is suitable for arrangement in a vertical, horizontal and inclined manner.

Title: Slide valves in the cylinder head on spark ignition and diesel engines
Inventor: SCHUEMANN HEINZ
IPC: F02B3/06
Filed: 1986-03-07
Abstract: Slide valves in the cylinder head on spark ignition and diesel engines are characterised in that the slide valves in principle function as conventional cone valves but transversely to the stroke direction of the cylinder bore in the cylinder head. The drawing shows the operating principle of the slide valve. The slide valve is moved in the cylinder head by the rotation of the camshaft. When the slide valve running in the housing is opened, the medium can be directed through the inlet or exhaust ports. In the opened state, the housing on the top and under side has the same ports as the slide valve. In the closed state, the ports are not congruent so that the flow of medium is blocked. The width of the ports is dependent on the highest or lowest position of the cam of the camshaft, which is laterally mounted. The structural form can be modified according to the requirements (circular form, number of ports). <IMAGE>
