Patent DE-3133464-A1 (DE)
Title: Method for controlling a light beam, in particular in phototypesetting
Inventor: BYCKLING EERO
IPC: B41B19/00
Filed: 1981-08-24
Abstract: The invention relates to a method for precisely controlling a light beam which is used in writing text or images, in particular in phototypesetting. Rulings, screenings or gratings consisting of slits (Sa-d) or lines (L1, L2) are provided on the frames of the focal planes and, in some applications, on the optics frame. The light beam and, in some embodiments, one or more reference beams, which have been separated from the writing beam, impinge the rulings (Sa-d) or gratings. The signal thus produced and observed by means of photodetectors conveys information on the relative position of the light beams, the rulings and the focal plane relative to one another. This information is converted by means of electronic circuits into information on the position of the writing beam on the focal plane. This information permits the position of the writing beam to be controlled with high accuracy by means of feedback mechanisms. In addition, the method can be set up for deflecting the beam so that the modulation of the beam can be synchronised with the deflection, and thus the pixel can be positioned accurately at the desired position. <IMAGE>

Title: Hydraulic drum brake for a motor vehicle
Inventor: HOVARDAOGLU RIZA
IPC: F16D65/22
Filed: 1981-09-10
Abstract: There is a hydraulic brake for motor vehicles in which two brake shoes (4) arranged in a brake drum are pulled towards one another and away from the drum cylinder by means of a spring (6), are pivotably mounted at the same end and are connected via a piston-cylinder arrangement (7) which engages on one brake shoe by a piston rod (8) projecting from a piston, engages on the other brake shoe by a second piston rod projecting from a piston and is connected to a conduit (14) for pressurised fluid. The intention here is to safeguard the functioning of the drum brake to a considerably improved extent against malfunctions by supplying the piston-cylinder arrangement via two branch conduits. This is achieved by dividing the piston-cylinder arrangement (7) into two cylinders (10), each of which accommodates one of the pistons (9) and to each of which one conduit branch (14) is led. If one of the two piston-cylinder units or its conduit branch is malfunctioning, the brake remains fully functional because of the other piston-cylinder unit. <IMAGE>

Title: Freezing protection for containers in which fluid is located
Inventor: SCHEFFLER GUENTER DIPL ING
IPC: F01P11/20
Filed: 1982-02-20
Abstract: In a drive for the accelerated and delayed movement of a mass (23) by means of a hydraulic motor (13), it is proposed for energy recovery during braking of the moving mass (23) that pressure medium which is forced out of the hydraulic motor (13) be supplied at least at times to at least one pressure reservoir (8) in order thus to be able to reuse the hydraulically stored energy during the subsequent operating cycle. In this way, the kinetic energy of the pressure medium itself and of the coupled masses can also be partially recovered and the total energy cost thus reduced. <IMAGE>

Patent DE-3241623-A1 (DE)
Title: Automatic time recording system for documentation purposes, with manual speech output
Inventor: TRAUTMANN REINHOLD
IPC: G11B27/32
Filed: 1982-11-11
Abstract: The automatic time recording is carried out by the fully automatic recording of the respective time criteria onto the sound medium by means of a speech generator with processor control. In addition to the useful signal, the time criterion of the respective recording time is also recorded onto the sound medium. A temporal reconstruction of a defining procedure is thus possible at any time, in any place and without ancillary equipment, and specific recording points are more easily and quickly located. The system operates fully automatically in two modes (serial and parallel recording) and is thus suitable for any recording frequency. The recording and reproduction of the time criteria are independent of the quality of the sound medium used and, provided that useful signal recording is still possible, the time criteria are also always completely and reliably recorded and reproduced.
Patent DE-3244761-A1 (DE)
Title: Concentration process and apparatus
Inventor: VAELIMAEKI HEIMO
IPC: A23C1/12
Filed: 1982-12-03
Abstract: A process and an apparatus are described for carrying out the concentration in at least two sequential, relative to the liquid to be evaporated, concentrators (1, 2) connected in series. In the evaporation, the heating vapour used is the vapour which is separated from the liquid to be evaporated in connection with the concentration process. This vapour is fed from both the first concentrator in the series and also from the next concentrator in the series to a main blower (13), which blows the vapour back to the concentrators at elevated pressure. In addition, an auxiliary blower (12) is used, which blows vapour separated in the following concentrator (2) in the series prior to its entry into the main blower (13). The auxiliary blower (12) is of substantially smaller size than the main blower (13) and the control of the process can be carried out exclusively by means of control devices attached to the auxiliary blower, by means of which the total energy consumption of the process is reduced and exact control of the solid content of the end product leaving the process is made possible. <IMAGE>

Patent DE-3305852-A1 (DE)
Title: Two-stroke diesel engine with opposed free pistons
Inventor: WAGNER ALBERT
IPC: F01B11/02
Filed: 1983-02-19
Abstract: In the case of a two-stroke diesel engine with opposed free pistons 2 and hydraulic pump 3 the reciprocal movement of the free pistons with complete balancing of masses in each cylinder is converted into rotary motion by the hydraulic oil delivered by the hydraulic pump or pressurised water by means of a hydraulic motor and/or a free jet turbine. On the return of the free pistons, the acceleration is largely produced by the air compressed in the buffer chambers of the free pistons. Instead of the hydraulic piston connections previously indicated, compressed air piston connections are now proposed, because in this case the pressure losses and the acceleration pressures are lower and the ducts 15 between each two cylinders are smaller and simpler. For the high piston speeds, nozzle cone valves are proposed for the pressure valves 31 and the intake valves 32 of the hydraulic pump, which cone valves have a low pressure loss owing to a heavy reduction of the high cracking speed in the expanded nozzle behind the valve seat associated with an increase in pressure. Starting is by way of a starter injection pump 11 with two pump pistons and starter compressed air valve 12 so that each cylinder has a starter injection. <IMAGE>

Title: Circuit arrangement for PCM telecommunications switching systems with test devices for functional testing of switched connections
Inventor: PURZER JOSEF
IPC: H04M3/24
Filed: 1983-03-02
Abstract: A test device (P) in PCM telecommunications switching systems for functional testing of switched connections can be looped via break plug blocks (x) into the PCM line by means of break plugs (y). Initially connected to the PCM line (PCM30F) only at the receiving end via a contact (1y), it is first synchronised to the line clock by means of a receive switching device (E). It then connects itself at the transmitting end, also via contact (3y), to the PCM line, whose direct switched connection, which had existed up until this time, it then isolates by means of the break contact (2y) in order to divert the switched connection onto itself. The test device (P) extracts PCM signals of a selected channel and/or inserts PCM signals for this channel, along with the corresponding components of the signal channel. The PCM signals of all other channels run through unchanged, along with the corresponding components of the signal channel. Furthermore, a selected channel can also be isolated during the test procedures by means of the break contact (2y) (data signals and/or line signals), while the other channels can continue their operation unhindered. <IMAGE>
