Patent DE-3405048-A1 (DE)
Title: Heating boiler for solid fuels
Inventor: WAGNER EDMUND
IPC: F24H1/44
Filed: 1984-02-13
Abstract: In a heating boiler for solid fuels, a firing door is provided on the front side which extends transversely in the upper region and which extends over practically the whole boiler width. The grate on the underside is arranged within the combustion chamber in the forward half of the boiler. Furthermore, several rows of individual pipes, which themselves have a respective bend or curve, are situated within the combustion chamber. The individual pipes are connected on both the feed and the return side to the rear boiler wall, through which water flows. Large pieces of solid fuel can thus be supplied in the transverse direction to the heating boiler, which overall has a compact structure and is consequently suitable as a heating boiler for a private household. The arrangement of the individual pipes is such that a good heat efficiency is obtained, the boiler is charged in a manner which is easy to operate, without jamming of the pieces of solid fuel, and especially, a cleaning of the individual pipes can be carried out easily.
Patent DE-3409672-A1 (DE)
Title: Break-in alarm system for self-installation
Inventor: RASCHEN JUERGEN
IPC: G08B13/08
Filed: 1984-03-16
Abstract: In order to reduce the costs for a break-in alarm system, to enable installation by lay persons and to avoid the previously costly installation and systems having satellites, all the important elements such as the alarm transmitter, alarm triggering device, alarm switching central unit, energy donor, door-lock switches, on and off switches are installed in a compact manner in or on the apparatus and are connected without electronics. In order to keep the apparatus as compact as possible, it is equipped with a movement switch which triggers the alarm by means of a pendulum movement, instead of a satellite (trip cord, etc.) which was previously necessary. In order to simplify self-installation, the previously necessary new installation of an electrical door-lock switch is replaced by the door-bolt switch, which rests flat on the lock which is already present and is designed such that it incorporates the bolt, which slides in and out, in its function. In order to produce the apparatus as cost-effectively as possible, it can be equipped with only one relay, which switches two separate circuits, instead of an electronics device which was previously necessary.

Title: Apparatus for automatically monitoring the flow of an irregularly flowing-out liquid
Inventor: LUECK WERNER
IPC: G01F3/24
Filed: 1984-03-28
Abstract: The invention relates to an apparatus for automatically measuring the flow of an irregularly flowing-out liquid, e.g. the urine flowing out of a catheter, the liquid amount measured being recordable electronically. At the same time, the discharge hose is guided through a hose pump which is controlled such that the liquid level at a marking in front of the entry to the hose pump is kept constant and the liquid amount which has passed through is measured by counting of the revolutions of the pump. The hose and the liquid sensor may form an exchangeable, disposable unit.
Patent DE-3413815-A1 (DE)
Title: Hydraulic, two-tube vibration damper which can be blocked
Inventor: WOJCIECH RUDOLF
IPC: B66C23/62
Filed: 1984-04-12
Abstract: It is intended to create a two-tube vibration damper in which the entire vehicle suspension, that is to say the springing in and springing out, can be blocked at any desired position, for example during the operating phase in the case of vehicles fitted with cranes. 
<??>This problem is solved in that the piston rod guide has a recess which runs into the flow connection between the operating space and the equalising space, in which recess there is held a servo piston which can be displaced axially, it being possible to produce an interruption in the flow connection between the operating cylinder and the equalisation space by applying pressure to the end surfaces.

Patent DE-3416391-A1 (DE)
Title: Extensible table
Inventor: SCHOELLER HERMANN
IPC: A47B1/02
Filed: 1984-05-03
Abstract: The extensible table (3) has two table top parts (31; 32) and an insert board (33). The table top parts (31; 32) are coupled to one another by means of an anti-rotation device. The insert board (33) is connected to a lifting device (34) which has two crankshafts (35; 36) which are coupled to one another by means of a coupling rod (46). An actuating rod (52), linked to one table top part (31), has an actuating journal (57) which engages on a control device (60), which is connected to the coupling rod (46) of the crankshafts (35; 36), after a certain movement path when the table top parts (31; 32) are pulled apart and, as a result, straightens the crankshafts and lifts the insert board (33). The control device (60) has two control links for the actuating journal (57). When the table top parts (31; 32), which are initially pushed up to the insert plate (33), are pulled slightly apart again, the actuating journal (57) is reversed, as a result of which, when the table top parts (31; 32) are subsequently pushed together, the crankshafts (35; 36) are bent round and the insert board is automatically lowered again. <IMAGE>

Patent DE-3422963-A1 (DE)
Title: Optoelectronic transducer
Inventor: SCHUMACHER ERWIN
IPC: G01H9/00
Filed: 1984-06-22
Abstract: An optoelectronic transducer contains a light source which emits an essentially parallel light beam or laser beam. Clamped at a prescribed distance from the light source is a diaphragm which deflects a deflectable low-mass mirror. The light beam is directed at an acute angle of incidence onto the mirror and reflected onto a light-sensitive sensor which emits a useful electrical signal proportional to the area exposed. In order to implement a particularly high sensitivity of the transducer - in conjunction with a good frequency response and low distortion - the mirror is mounted in a hinged fashion on a joint on a side edge at a prescribed distance from the diaphragm and coupled in a hinged fashion to the diaphragm on the opposite side edge.

Title: Electronic analog/digital converter
Inventor: STEINBACH GUENTER DIPL ING
IPC: H03M1/00
Filed: 1984-07-18
Abstract: A two- or multi-stage electronic analog/digital converter suitable for construction as an integrated circuit, for conversion of an analog (continuously variable) electrical input variable into a digital (discretely variable) output number, the stages in each case consisting of a parallel analog/digital converter and - in all stages apart from the last stage in the signal path - an amplifier selection circuit and a bank of differential amplifiers which can be individually switched in and out, arranged in such a manner that for each quantisation interval of the input variable, which can be resolved by the parallel analog/digital converter of the relevant stage, exactly one amplifier amplifies the difference between the value of the input variable and a reference voltage characteristic of the relevant quantisation interval when it is switched in by the parallel analog/digital converter of the relevant stage via the amplifier selection circuit, and forwards this amplified difference as input variable for the stage following in the signal path. This provides for faster conversion than in other multi-stage analog/digital converter concepts.

Patent DE-3436440-A1 (DE)
Title: Semiconductor measuring instrument
Inventor: POPPINGER MANFRED DIPL PHYS DR
IPC: G01L9/00
Filed: 1984-10-04
Abstract: The invention relates to a semiconductor measuring instrument with a sensor chip disposed in a housing, especially a silicon pressure sensor, which sensor chip via an intermediate support is disposed on a metallic or ceramic extension piece. In fabricating such semiconductor measuring instruments, the semiconductor materials must be joined to the materials of the extension piece by soldering processes. Owing to the different thermal expansion coefficients of the different materials, mechanical stresses are caused in the sensor chip upon cooling after soldering which show up as unwanted changes of the characteristics and can generally be compensated only with a major effort in terms of testing and compensation. According to the invention, the intermediate support (15, 25, 35) on its back has an annular groove (16, 26, 36) running outside the extension piece (2, 32). By virtue of this simple fabrication measure which is achieved with little effort by etching or electroerosion, the prestress of the sensor chip can be substantially reduced. In an advantageous further refinement, the intermediate support (25, 35) may additionally have a cutout (28, 38) on its side facing the sensor chip (20, 30). <IMAGE>
Patent DE-3438842-A1 (DE)
Title: Remote control system with two receivers
Inventor: ALTROGGE WILHELM E DR ING
IPC: G07C9/00
Filed: 1984-10-24
Abstract: Remote control systems with coded signal transmission for, for example, automatic gates, have an average power consumption of 0.5 watts at the receiver end. However, this is much too high in connection with an advanced compact drive on the gate. The 12-volt battery of this drive has a capacity of 10 Ah. The invention uses a wireless remote switching of the coded receiver, integrated into the respective remote control system. The additional receiver operates opto-electronically and consumes minimum current. It switches the coded receiver on in each case only for the coded signal transmission so that it consumes virtually no more current. The additional opto-electronic receiver is triggered by directionally radiating a single short light flash. For the selective receiver, the light flash is advantageously distinguishable from the light phenomena in the environment. The light signal source is included in the housing of the commercially available remote control transmitter. When a push button is operated, light flash and radio signal or infrared signal automatically follow in a brief sequence. A greater range is achieved with a spark gap as light source. This makes it possible fully to utilise the signal distance of remote radio controls.

Title: Method and device for testing the internal pressure of tubes, in particular of gun barrels
Inventor: KNAEBEL HORST DIPL ING
IPC: G01N3/12
Filed: 1985-02-12
Abstract: In a method for testing the internal pressure of tubes, in particular of gun barrels, a high pressure required for the testing is built up in a tube which can be closed at both ends and is completely filled with pressure liquid, and the loading of the tube occurring in this case is measured. In order to achieve within a few milliseconds a pressure build-up which largely corresponds along the tube to the tube design and thus to the actual later loading of the tube, an elongated piston which projects sealingly through an endpiece into the tube to be tested, forming a restrictor gap in so doing, is subjected at its end projecting from the endpiece to loading by a force unit which acts impulsively, resulting in the generation in the tube of a sudden pressure rise which propagates, via the restrictor gap, up to the endpiece penetrated by the piston, from the internal free end of the piston, in conjunction with simultaneous reduction. <IMAGE>

Patent DE-3533614-A1 (DE)
Title: Spiral wire belt
Inventor: KRENKEL BERNHARD DR
IPC: D21F1/00
Filed: 1985-09-20
Abstract: The invention relates to a spiral wire belt in a single-ply and multi-ply design, consisting of a multiplicity of spirals of plastic material arranged one behind the other with interlocking turns. Since the relatively low longitudinal stability of spiral belts of polyamide has hitherto prevented their use in drainage machines, and even a combined use of polyester and polyamide for the spirals does not eliminate the said disadvantage, it is to be regarded as the object of the invention to develop the spiral wire belt of the said type in such a way that, in spite of using polyamide spirals, a longitudinal stability and dimensional stability with a simultaneous improvement of the wear resistance of the belt are achieved which eliminate problems from the use in drainage machines. This is achieved if at least some of the spirals are formed in at least one ply of the multi-ply wire belt as twin spirals of polyester and polyamide.
