Patent DE-3215484-A1 (DE)
Inventor: NYGREN BO HAAKAN DR
IPC: G01N33/52
Filed: 1982-04-26
Abstract: A member for detecting and/or measuring the level of concentration of a chemical substance in a medium comprises a non-metal substrate bearing a dielectric layer. A detection reactant which is capable of reacting with the substance to be detected is put on the dielectric layer and the assembly is put into the medium to be investigated, whereupon an optically detectable layer of the substance to be detected is formed on the detection reactant. The substrate is light-absorbing and one or more further dielectric layers is or are disposed between the substrate and the first-mentioned dielectric layer thereon, the thickness of the further dielectric layer or layers being such that the overall assembly comprising all the dielectric layers, the layer of detection reactant thereon and the layer of substance to be detected, is reflection-reducing in respect of non-monochromatic light which is reflected at the surface of the substrate on which the array of layers is disposed, in the wavelength range of from 525 to 600 nm.

Title: Circuit arrangement for activating switching points operating on the time division multiplex principle in telecommunications switching systems, in particular telephone switching systems
Inventor: GAERTNER PETER DIPL ING
IPC: H04Q11/04
Filed: 1982-05-05
Abstract: The circuit arrangement according to the invention indicates how addresses, which are read out from a switching memory, of connection devices which are to be interlinked are recorded in a buffer register if they are not read out at a switching time. The addresses stored in the buffer register are then decoded along with the addresses read out at a switching time, are offered to a switching register whose outputs are directly connected to the activation inputs of switching points. These activation inputs are connected in such a way that addresses read out at different times produce a switching of connections which is simultaneous although it occurs on separate paths. A plurality of bus systems are therefore provided, two of which are in each case combined for connections requiring four-wire switching.

Patent DE-3308974-A1 (DE)
Title: Digital device for measuring or positioning
Inventor: POPPE RUDOLF DIPL ING
IPC: G01D3/02
Filed: 1983-03-14
Abstract: The invention relates to a device for measuring or positioning which operates with a contact arm. The aim is a device having a wide range of use and a high measurement accuracy. The object is achieved on realising relatively large contact arm deflections and, in so doing, compensating bending influences of the system. The invention realises this by tiltably supporting the contact arm in the movable cross-member of a leaf-spring parallelogram, by a load-relieving lever which acts on the movable cross-member, and by an adjustable lever via which a movably mounted scale follows the movable cross-member. In this case, the electromagnetic lifting of the contact arm is performed by means of a transmission lever, and a zeroing or setting of the counter downstream of the photoelectric scale scanning is performed in the zero stop position of the movable cross-member. In this case, the value for setting is advantageously equal to or greater than the limit value up to which a corruption of the measured value occurs which has its cause in the increase in the measuring force up to the lifting of the movable cross-member from the zero stop. It is advantageous to arrange a damping lever mounted between springs in the load-relieving lever. <IMAGE>

Title: Device for treating workpieces by means of temperature and pressure surges
Inventor: CONRAD HANS-JUERGEN
IPC: B23K7/06
Filed: 1983-09-15
Abstract: A device for treating workpieces by means of temperature and pressure surges by igniting a gas mixture, in particular a thermal deburring unit, is proposed, the machine frame of which consists of three columns (1, 2, 3), forming the corner points (A, B, C) of a preferably equilateral triangle, and two plates (15, 16) having plane-parallel faces and fastened to the columns (1, 2, 3). A workpiece-treatment chamber (4) and its closing system (5) are arranged in the centre (P) of these plates (15, 16). Extensions attached to the columns (1, 2, 3) serve as standing legs (6, 7) of the unit. A very simple machine frame is thereby obtained which is inexpensive to produce and can be operated in a space-saving manner. Due to the concentric arrangement of the workpiece-treatment chamber (4) and the closing system (5) inside the machine frame (1, 2, 3, 15, 16), the pressures which occur are uniformly distributed over the individual components of the machine frame. This permits a reduced cross-sectional design of the plates (15, 16) and the columns (1, 2, 3) without the productive capacity of the unit being impaired. <IMAGE>
Patent DE-3344037-A1 (DE)
Title: Connecting flange for eliminating pipe blockages
Inventor: BALDUS HELMUT DIPL ING
IPC: F16L41/00
Filed: 1983-12-06
Abstract: The invention relates to a connecting flange for eliminating pipe blockages. The main features consist in the fact that this connecting flange can be mounted on any commercially available siphon inlet. The spacing screw permits the flange to be attached to the inlet in an air-tight or water-tight manner. The screw thread on the upper part of the flange permits a commercially available threaded hose coupling to be attached, by which means air or water can be injected for the rinsing process. As a result, the pipe blockage is eliminated. Figure 2 represents a seal of the overflow which is attached in the case of a back up. The advantage with respect to previously known methods lies in the fact that scouring cannot occur as is the case with known chemical agents. No damage occurs as is the case when using a coil. The handling of the flange does not require any skilled knowledge. There is no damage to the environment.
