Patent DE-3639150-A1 (DE)
Inventor: GOETTLING HELMUT
IPC: F15B15/28
Filed: 1986-11-15
Abstract: In a potentiometer, for reliability reasons it is necessary for the contact member, which interacts with the resistance track and can be driven by an operating member, to be supported such that it cannot rotate with respect to the resistance track. In order that the operating member can be rotated with respect to the contact member, known potentiometers have a joint between the contact member and the operating member. Such a joint is costly to manufacture. 
<??>In order to permit a rotational movement between the contact member and the operating member, without a joint having to be provided between these two parts, a permanent magnet (10) is arranged on the operating member, as shown in Fig. 1, which permanent magnet (10) interacts with a part (22) of the contact member (15, 16, 22) consisting of a ferro-magnetic material. In the case of a shifting movement of the operating member, the contact member (15, 16, 22) is driven by magnetic force without contact, i.e. is driven along the resistance track.

Title: Switching arrangement for the reversing switch of a tapping switch for transformers
Inventor: SCHMIDT HARALD
IPC: H01H9/00
Filed: 1987-06-12
Abstract: The object of the invention is now to create a reversing switch which has a polarity resistance which need be designed only for a brief and low load and is thus relatively small, and in the case of which no switching sparks occur between the contacts during switching. The two moving switching contacts (6) switch simultaneously between two stationary contacts (4, 5), a polarity contact (3) being arranged between them, in the same plane and on the same circular path. The polarity contact (3) is connected via the polarity resistor (2) to one stationary contact (5), and the control winding (1) is connected to both stationary contacts (4, 5). The centre of rotation of a moving auxiliary contact (8) is located on the support (20), most favourably on the angle centre and on a circular path between the contacts (4, 5), and is constructed as a sliding contact. In addition, a restraining magnet (9, 10) is provided, whose armature is insulated. When no current is passing through the restraining magnet coil, the armature (10) restrains the moving auxiliary contact (8). <IMAGE>

Title: Device and method for controlling the firing point in an internal combustion engine
Inventor: MIENO TOSHIYUKI
IPC: F02P5/152
Filed: 1987-07-22
Abstract: According to the invention, a method and a device for controlling the firing point in an internal combustion engine are provided, in which the firing point is determined on the basis of the internal combustion engine speed for the load condition, a distinction is made on the basis of the output of a knock detection circuit as to whether or not knocking has occurred, the firing point thus determined is put back or retarded by a predetermined value if knocking occurs and the firing point brought forward or advanced by a predetermined value once knocking has been prevented. The maximum value of the ignition retardation and ignition advance which is allowed for if knocking occurs varies as a function of one or more operating conditions of the internal combustion engine, making it possible to adjust the firing point close to MBT and to obtain the maximum possible output power of the internal combustion engine. The operating condition or conditions of the internal combustion engine comprise an engine speed in the case of compensation in the direction of an ignition retarding adjustment and an internal combustion engine speed and a load condition in the case of compensation bringing about an advancement of the firing point.
Patent DE-3726119-A1 (DE)
Title: Rapid starting device for motor vehicles stopping at traffic lights
Inventor: WOLFF HANS-DIETRICH
IPC: F02N5/04
Filed: 1987-08-06
Abstract: For reasons of pollution control and avoiding uneconomic energy consumption, attempts are being made to get the drivers of motor vehicles stopping at traffic lights to always switch off their engines and to restart them only when the traffic lights change. Unfortunately, however, such a recommendation has hitherto not gained sufficient acceptance. The reason for such failure is doubtless the fear of drivers that the engine possibly might not start again and also that the battery might be rapidly drained by too frequent starting, thereby taking the incentive to save fuel to absurd lengths. A further reason is without doubt also the tediousness of the operation still currently necessary and unavoidable in most vehicles of normal type which, given a certain stress situation at the traffic lights, is perceived as especially irksome. For this reason, it is proposed here that the energy needed for restarting be obtained not from the battery but for no cost and reliably from a flywheel which, preferably by using a magnetic clutch, is automatically uncoupled from and coupled to the engine when switching the engine off and on and thus forcibly and powerfully starts the engine on recoupling. The flywheel device proposed according to the invention can according to the invention be retrofitted to any engine at moderate assembly cost in place of the radiator fan.

Title: Aperture correction method for video signal
Inventor: WALDRON CHRISTOPHER JOHN
IPC: H04N5/253
Filed: 1987-12-11
Abstract: Aperture correction is provided by forming two treatment signals. Each treatment signal is formed from a respective pair of samples of the untreated video signal. Each pair comprises samples taken at a sample point ahead of the detail to be treated and at a sample point behind the detail. These treatment signals represent a high and a low frequency correction signal and are combined with the original video signal invariable proportions set according to the degree of correction required. The proportions are set for each scene of a film, for each frame or for each portion of a frame and recorded in a pre-programming system. Furthermore, the proportions can be chosen to generate special effects such as soft focus.

Filed: 1988-03-12
Abstract: The invention relates to a container 1 for fighting coal-dust and/or firedamp explosions in underground workings and which serves to hold an extinguisher fluid, being adapted to be mounted on the timbering or the like, and consisting of a bottom 4, one or a plurality of walls 2, 3, 6, 7 and possibly a top cover. In order to provide a container 1 of the aforementioned type which has optimum qualities in terms of a high response sensitivity and a high capacity to resist loadings of all types, it is according to the invention proposed that at least one component part or parts thereof of the container 1 is or are pivotally connected to at least one component part or parts thereof of the container 1 which is adjacent to it. It is thus ensured that the pivotally connected constituent parts of the container 1 are pivoted away from the pressure wave occasioned by the explosion while at the same time the extinguisher fluid contained in the container 1 is released and fills the entire gallery cross-section in ultra-fine dispersion. After triggering by the pressure wave caused by an explosion, the constituent parts of the container 1 have a greatly reduced substantially linear cross-section, when viewed from the direction of the explosion. <IMAGE>

Title: Method for producing a drive unit having gas bearings
Inventor: LUEDENBACH BERNHARD
IPC: H02K15/16
Filed: 1988-05-24
Abstract: Rapidly rotating drive units, for example for spindles in the textile industry, are welded or soldered on both sides of the stator (1) of the driving electric motor to bearing shells (5) consisting of porous sintered metal, and the bearing shells are subsequently machined to size and possibly sealed (6) on their surface, to be precise in a clamping device, in order to ensure correct alignment of the bearing surfaces. The shaft (2) with the integrated rotor (3) is not machined to size, in the same manner, until it has been installed. It is thus possible to implement narrow bearing gaps, which result in the gas bearings having a stable and vibration-free behaviour. <IMAGE>

Title: Radio-frequency plasma source and ion source for continuous operation
Inventor: FREY HARTMUT
IPC: H01J27/16
Filed: 1988-08-03
Abstract: The proposed radio-frequency plasma source and ion source has a double-walled electrically insulating plasma discharge vessel, the inner cylinder of the plasma discharge vessel (7) being longitudinally slotted. During operation of the source, the plasma discharge vessel is charged positively; there is therefore no sputtering of the vessel. During operation of the ion source, no discharge is struck between the inner wall of the discharge chamber (2) and the outer cylinder of the plasma discharge vessel (7). A substrate holder which can be cooled and to which permanent magnets are fitted can be inserted into the plasma discharge vessel, from which substrate holder solid materials can be dusted off reactively or even inertly. The solid material atoms are ionised in the plasma and are then accelerated by the extraction system. The potential of the substrate support can be set by means of block capacitors. The source can be operated in the electron-cyclotron resonant frequency regime by impressing a DC component onto the radio-frequency induction coil (5). This results in a very high ionisation level of the plasma. The source is maintenance-free since no undesireable sputtering effects occur in the plasma discharge vessel (6, 7). The ion beam or plasma beam is free of impurities. As a result of the extraction grids being coated with dielectric materials, they are not sputtered either. The ion source can also be operated using solid materials, since the design of the ... Original abstract incomplete. <IMAGE>
Patent DE-3831674-A1 (DE)
Title: Continuously variable roller-chain drive
Inventor: WUERTH GUSTAV
IPC: F16H9/24
Filed: 1988-09-17
Abstract: In the continuously variable roller-chain drive, a roller chain runs over roller sprockets, guided on spokes, of two spoked rings. To achieve altered, continuously variable transmission ratios, the roller sprockets of one spoked ring are moved inwards and the roller sprockets of the other spoked ring are moved outwards, the movement in each case being effected mechanically, hydraulically or electrically, and the roller chain is thus always under the same tension. In order, on the one hand, to prevent the roller sprockets from rotating, and, on the other hand, to ensure that the roller chains always engage in the interspaces of the roller sprockets as the distances from the axis of the spoked wheel are changed, the shafts are firmly connected to the roller sprockets and directed towards the outside and are there likewise further connected to a sprocket which engages in a rack guided parallel to the spoke. This ensures both that a rotation of the roller sprockets is made impossible and that the sprockets always engage in the interspaces of the roller chain. Slip is thus avoided.

Patent DE-3837642-A1 (DE)
Inventor: SEIDEL JUERGEN
IPC: B21B1/46
Filed: 1988-11-05
Abstract: In the manufacture of hot-rolled steel strip, the strip-shaped cast billets coming from the casting plant are wound up in an intermediate storage means to form a coil and are unwound again after heating and fed to a rolling mill for rolling out to a certain final thickness of cross-section. Here, however, it is of disadvantage that the cast billets discharged from the casting plant have to be stored and preheated in an intermediate storage means before they are fed to the finish rolling mill. This involves the need for more equipment, greater expenditure of energy and increased costs. The arrangement of an intermediate storage means also requires more space. According to the invention, however, these disadvantages are removed due to the fact that the continuously cast feed stock, after heating in the compensating furnace (3, 4) is fed to a multiple-stand, reversible finish rolling-mill train (10) having a coilbox (14) attached thereto.
