Patent DE-3716069-A1 (DE)
Title: Charging device having automatic polarity and charging voltage selection, automatic disconnection and undervoltage connection protection for rechargeable batteries, and a simple precision signalling and switching device
Inventor: SORGATZ WOLFGANG
IPC: H02J7/00
Filed: 1987-05-14
Abstract: The invention claims relate to fully automatic battery charging devices, especially as additional devices for normal, commercially available battery charging apparatuses, and to circuits for precision switching or measurement apparatuses. Charging apparatuses equipped in accordance with the described inventions (Patent Claims 1 to 8) are distinguished by the following special features: Automatic polarity changing, automatic charging voltage selection and automatic final charging voltage disconnection; non-live connecting terminals, that is to say there is no longer any need to be concerned about the correct polarity, the correct charging voltage or a short circuit between the open connecting terminals when charging a battery using an automatic charging apparatus equipped in this way, and the battery cannot be overcharged. Only a minimal operating cost is thus still required for such charging devices, for the first time. Simple and safe handling is quick and easy even for laymen. The designs of the said inventions are based on the first-ever implementation of the basic idea of developing simple, functionally reliable and cost-effective automatic circuits with a constant-value voltage regulator and a time transmitter circuit, and of combining them with automatic polarity and voltage devices. Simple, functionally reliable and cost-effective alarm, signalling or switching apparatuses can likewise be produced by minor changes to this basic circuit and the connection of suitable sensors ...

Title: Method and appliance for operating a pressurised electroslag remelting plant
Inventor: HOLZGRUBER WOLFGANG DIPL-ING D
IPC: C22B9/18
Filed: 1987-07-03
Abstract: A method for operating a pressurised electroslag remelting plant with a permanent mould, especially with a permanent copper mould and water cooling, and a pressurised electroslag remelting plant with a permanent mould, especially with a permanent copper mould and water cooling are designed to enable, inter alia, the manufacture of blocks without resulting, on the one hand, in unwanted denting and bulging of the permanent mould, and without voids (blisters) or pores forming in the blocks. To this end, the pressure of the water used for cooling is kept at such a level that it does not exceed or fall below the gas pressure within the plant by more than 5 bars. The water is circulated in a closed pressurised-water circuit and the heat rejected to the cooling water via the permanent mould is passed, via a heat exchanger, to the recooling system. If the cooling-water pressure drops, excess water, on the one hand, and gas, on the other hand, are discharged. To this end, a device is proposed for maintaining the pressure of the water used for cooling at such a level that it does not exceed or fall below the gas pressure within the plant by more than 5 bars, by means of a pump (14) in a closed pressurised-water circuit, by means of a heat exchanger (15) via which the heat rejected to the cooling water via the permanent mould (4) is passed to the recooling system, there being, on the one hand, an ancillary element (22) allocated to the pressurised-water circuit as an outlet for excess water, and, on the other hand, a ...

Patent DE-3723673-A1 (DE)
Title: Externally controlled non-return valve
Inventor: MICHAELIS LOTHAR
IPC: F16K15/18
Filed: 1987-07-17
Abstract: An externally controlled non-return valve which allows free flow in one direction with a non-return valve action and, in the other direction of flow, has a shut-off action which can be cancelled by means of control from outside has a valve cone 2 as the sole moving functional part. This valve cone 2 is not sealed off by soft packings. It has a collar 15 and a cylindrical extension 16 which, in conjunction with the housing 1 and the cover 3, form a differential area in the control space 18. This differential area is larger than the area of the bore 13 which forms the connection 26 so that, when the pressure in the control space 18 is relieved, a resultant force acts counter to the compression spring 5 and the valve cone 2 rises from the conical seat 14. Relief of the pressure in the control space 18 is performed by connecting the connection 20 to the tank by means of a pilot control valve 31. A land 22 formed because of the annular notches 21 and 23 gives rise with the fit of bore 17 in the cover 3 to a restriction which allows the valve cone 2 to close again only when the tank connection of connection 20 is sealed. The connections 25 and 26 lie on the valve axis and can be connected via the central bore 28 and the radial holes 30 of the valve cone 2 and the annular space 29, with the result that axial connection of connection fittings or control valves is possible and this is advantageous in terms of assembly. <IMAGE>

Abstract: Process for the preparation of dialkylbenzenesulphonic acids which are low in tar and sulphuric acid from the bottom alkylate of the synthesis of linear alkylbenzenes, in which process   a) a bottom alkylate in the form of the distillation residue of the synthesis of linear alkylbenzenes from chlorinated paraffin and benzene is fractionated using an aluminium chloride catalyst in such a manner that a fraction is obtained whose boiling range is from approximately 400 to 435@C and which contains not more than 16% by weight of diphenylalkanes,   b) this fraction is sulphonated using gaseous sulphur trioxide, c) most of the tar and sulphuric acid is removed from the sulphonation mixture by a precipitation with mineral oil or synthetic oils or a mixture of these, and d) the remaining sulphuric acid is precipitated as calcium sulphate using inorganic calcium compounds in the presence of small amounts of water.
Patent DE-3727434-A1 (DE)
Title: Arrangement for transfer of data words which are divided into several data items
Inventor: KNAUER DETLEV DIPL ING
IPC: G06F15/167
Filed: 1987-08-17
Abstract: During the transfer of data words, which are divided into several data items, between two control units (STE1, STE2), which work at different speeds, there is the problem that the two control units can access the same memory area simultaneously, and that one control unit changes a data word while the other is reading it. In this way, falsified data words are read. To solve this problem, the addresses which the control units access are compared. If they are equal, a logic circuit ensures that one control unit (STE2) only accesses the memory area when the other (STE1) has written a data word completely to this area, or has read it completely from this area. The invention is used for the adaptation of the interfaces of automation devices. <IMAGE>
Patent DE-3729107-A1 (DE)
Title: Refuse collection vehicle with reversing safety feature
Inventor: BAATSCH SIEGFRIED
IPC: B60Q1/22
Filed: 1987-09-01
Abstract: In refuse collection vehicles, refuse collectors are reliably prevented from travelling on the vehicle footplates when it is reversing by virtue of the fact that the footplates are connected to the chassis so as to trigger a contact switch when loaded. The contact switch addresses a relay which acts as an engine deactivator, a precondition always being the corresponding load on the footplate, that is to say the actuation of the contact switch and also the engagement of the reverse gear. The latter is ensured in that the contact switch is supplied with current via the supply line of the reversing light. <IMAGE>

Title: Spot-type disc brake with pressure-controlled counter-compensation
Inventor: WINTER KLAUS
IPC: F16D65/18
Filed: 1988-02-17
Abstract: Even in the case of moderate braking powers, brake lines of spot-type disc brakes can wear parallel to one another but obliquely to the bases of the brake disc. It is the object of the invention to provide controllable compensation of the forces causing the oblique wear of the lines. The solution provided by the invention consists in that the pin guides for the brake calliper are modified in such a way that they act like hydraulic cylinders, both acting parallel to the axis relative to the brake piston but in different directions as regards the force. The cylinders are advantageously subjected to the brake pressure of the brake cylinder. A hydraulic connection between the cylinders and the brake cylinder can be achieved in an advantageous manner by means of a continuous coaxial bore of the bleed valve. <IMAGE>

Title: Forward-viewing mirror system for motor vehicles for avoiding collisions
Inventor: ECKERT ROLF DIPL ING
IPC: B60R1/10
Filed: 1988-03-08
Abstract: When travelling in queues on straight sections, a forward view of the braking lights, which are still fastened beneath the car glazing, of motor vehicles travelling in front is generally blocked by the vehicle in front. The braking signal of the latter is, however, several reaction seconds too late, owing to the cumulative effect, if only one vehicle in the queue fails to observe the safety distance (which takes about 2 seconds to cover) to a significant extent. The lane width, especially when impeded by lorries, does not permit many drivers to look forwards by (in the case of left-hand steering) travelling to a limited extent on the left or more on the right. A pair of forward-viewing mirrors is proposed on the outer left and right along with a pair of mirrors which corresponds with the former pair in the straight-ahead viewing field of the driver, the latter pair of mirrors warning in a way which cannot avoid attention of a red light becoming illuminated further forwards, to permit braking readiness to be achieved in good time. For this continuous observation of the queue in front to take place, hardly any staggering with respect to the rest of the queue is required, which constitutes a new contribution to safety, which is mainly due to the system of mirrors on the right side. Forward-viewing mirrors for assistance in overtaking and manoeuvring are known, but these require the driver to stop looking straight in front and therefore cannot be continuously monitored.

Patent DE-3812703-A1 (DE)
Title: Ventilated cap for fluid reservoir
Inventor: RYAN DESMOND
IPC: B60T11/26
Filed: 1988-04-16
Abstract: In fluid reservoirs a ventilated cap ensures that an excess pressure or a partial vacuum does not occur due to the admission or the outflow of medium stored in the fluid reservoir. For this purpose the fluid reservoir has a ventilation opening, which can be closed by a valve in many different ways. A disadvantageous feature in the known ventilated caps is that with the surface of the stored medium (fluid) inclined due to an inclination of the reservoir or due to acceleration forces, some of the stored fluid may be lost. The object of the invention is to create, by simple means, a remedy for this by proposing a valve, which is in principle closed by these very forces which, in themselves, lead to a loss of the stored fluid.   <IMAGE>

Title: Two-row rolling contact bearing
Inventor: BRANDENSTEIN MANFRED
IPC: F16C19/18
Filed: 1988-07-07
Abstract: In a two-row rolling contact bearing, one of the races 1, 3 is provided over an arc of 240 degrees with a slot 4 in a radial plane between the tracks 2. As the rolling elements 11 are introduced, a ring segment 7 formed in the process is bent axially by the width of the slot. As a result, the spacing between the outer race 3 and the inner race 1 is widened at one point and allows the rolling elements 11 to be introduced without trouble. A spacer element 12 in the form of a partial ring is then inserted into the slot 4. Depending on the embodiment, a separating joint 13 can also be provided, in which case the ring segments 7 formed are moved away from one another. <IMAGE>

Title: Method for determining the instantaneous location of a mobile radio station
Inventor: ROSENEGGER WOLFGANG DIPL ING
IPC: H04W64/00
Filed: 1988-08-12
Abstract: The invention is based on the object of carrying out position determination from a mobile radio station in order that the result of the position determination is passed on to stationary radio stations only with the agreement of the user. In addition, the technical complexity for the implementation of the method is intended to be as low as possible. The object is achieved in that the mobile radio station (M) buffer stores data messages (DF1, DF2, DF3), which have been received from at least three stationary radio stations (F1, F2, F3), in a computer (C) in the mobile radio station. The instantaneous location is then determined by the computer using the propagation time differences ( DELTA t1,  DELTA t2,  DELTA t3) between the transmission of the respective data messages and the reception of these data messages, and locations, stored in the computer of the stationary radio stations. A preferred field of application for the method according to the invention is the German Federal Post Office OemL Network C. The drawing shows the time sequence of transmission and reception of the data messages. <IMAGE>

Title: Sensor device for polygraphic machines
Inventor: LINDNER JUERGEN
IPC: B65H43/00
Filed: 1988-08-30
Abstract: The invention relates to a sensor device for polygraphic machines for the detection of curved printing materials, especially for the detection of their edge positions. It is the object of the invention to provide a device for the detection of edge positions and/or lengths of curved materials which has a greater sensitivity and ensures a higher functional reliability. The technical object of the invention consists in designing the device so that disturbing factors such as the influences of extraneous light, soiling and radio-frequency fields can be compensated. The object is achieved in that a device carrying out a phase comparison of the received signals with the phase positions of the transmitted signals is assigned to the sensors, as is a device evaluating the dynamic behaviour of the sensors during predetermined clock signals. The sensors with the transmitters assigned respectively to them are advantageously designed as light barriers to which infrared filters are assigned and the device carrying out the phase comparison consists of a comparator circuit monitoring the pulse train for phase shift or coincidence of the progressions with time. <IMAGE>
