Title: Radiation reflective film - has metallised information layer, typically silver or aluminium on base layer and thin plastic coating read by laser
Inventor: POESCHEL EVA DR
IPC: G03C1/825
Filed: 1980-04-03
Abstract: The high density data recording system uses a disc with information stored and read by an optical system that uses a laser beam that is reflected off metallised areas. The system is designed to provide an improved technique for production of the metal coating with high accuracy. The process begins with a blank of a heat conducting material that is coated on both sides with a reflecting surface. This can be produced by vapour deposition or by a galvanic process. Information is stored in the metallised layer using a conventional process and the surface is coated with a lacquer of not more than 5 micron thickness. An alternative process uses a pressing operation for forming the metallised layer, which may be of silver or aluminium.

Title: Radio signalling system for mobile subscribers - has fixed stations, each with direction finder with rotary directional diagram
Inventor: ESPRESTER RALF DIPL ING
IPC: G08G1/123
Filed: 1980-05-02
Abstract: The system includes fixed stations in which are evaluated the radio messages, transmitted by the moving subscribers, this evaluation being carried out w.r.t. the information contents and direction of transmission. Each fixed station has a direction finder with an omnidirectional diagram and a single-channel receiver. Pref. the message comprises, in addition to the information part, a preposition signal for synchronisation of the receiver. The radio message, transmitted by a moving subscriber, may consist of two subsequent, identical signals. On reception in the fixed station the circulation direction of the omnidirectional diagram is reversed between the two subsequent signals. An Adcock aerial with a rotary goniometer may be used as the direction finder aerial. The latter may contain an array of directional aerials, aligned on different azimuths, these aerials being connected to the receiver in a cyclic sequence via switches.

Title: Plug-in electrical component board - has locking latch and integral switch on cover plate to prevent withdrawal while on and generation of sparks
Inventor: STEINKE WERNER
IPC: H05K7/14
Filed: 1980-07-03
Abstract: The plug-in component board (1) which supplies power to other units in a component magazine has a switch (3) positioned by the front cover plate (2), with its operating lever formed as a rocker arm (4). The front plate (2) has a hole (5) in it into which the board withdrawal tool is inserted, and a slider (6) - formed from a flat material - which can be displaced vertically up or down the rail formed by a section of the front plate (2). The slider (6) has a flat projection (7), protruding at right angles to it, which pushes the switch rocker (4) into the 'off' position when the slider (6) is at the lower end of its travel. When the slider (6) is in this position, a flat plate attached to it uncovers the hole (5) in the front plate (2) and allows the withdrawal tool to be inserted. The slider (6) also has a locking nose (8) which hooks under a cross rail (9) in the component magazine when it is in the 'up' position. This makes it impossible to withdraw the board without the switch (3) being pushed into the 'off' position.
Patent DE-3030437-A1 (DE)
Title: Parallel feedback operational amplifier - has multiple inputs split into two groups which can differ in gain
Inventor: SCHMIDT HANS JOACHIM
IPC: H03G3/04
Filed: 1980-08-12
Abstract: The input signals to the amplifier (V) are split into two groups (I:U1,U2,U3;II:U4,U5) with the object of achieving different gain for each group and preventing interaction between inputs. Connection of all groups is through the normal impedance matching and voltage setting resistors (e.g. R1,R11, R12). The first group (I) is commoned and connected to the virtual earth point (E) through an impedance (Z1) by which the gain can be trimmed. The amplifier feedback is taken from a matching network (A) through a four pole damping network (D) and a variable resistor (R6) to the inverting input of the amplifier. The second group (II) is coupled through a trimming impedance (Z2) to a second virtual earth point (P) between the variable resistor (R6) and the damping circuit (D). The second group inputs are effectively isolated from each other by the virtual earth (P) and also have no effect on the inputs of the first group (I). The latter are also isolated from each other but, due to the drop across the variable resistor (R6), can influence the second group inputs. This effect can be reduced to negligible proportions by making the second group input resistors (R4,R5) very much greater in value than the variable resistor (R6).

Abstract: All rollers outside the working stations on the textile machine, which bear against or are within loops of the tangential drive belt, are placed at fixed intervals. Designed for operating a number of spindles or open-end spinning rotors, the layout allows the use of commercially available drive belts, without requiring a tensioning unit as the belt tension remains constant within satisfactory tolerances. A laying unit fits and tensions the tangential drive belt, as an assembly which it temporarily attached to the machine for the purpose, using mounting points. A pulling gear on the laying unit has a clamp to grip both levels of the belt. The pulling control is attached to the end of the machine near the belt deflecting roller, the belt drive roller and/or the belt path, to be locked at a fixed point on the textile machine frame.

Title: Circuit arrangement for a telephone private branch exchange which consists of a main installation and at least one private branch exchange
Inventor: LOICHINGER JOHANN DIPL ING
IPC: H04M7/14
Filed: 1981-09-18
Abstract: In order to handle switching processes which relate to specific line features and/or for the purpose of central call data acquisition (which is provided in the context of determining charges), it is necessary to know that subscriber point (TU) of a private branch exchange (UA) for which a connection is to be produced in the outgoing or incoming direction. As such a performance feature it can be provided, for example, for switching systems having an illuminated digit display at the switching station that, in the cases in which the desired subscriber to a private branch exchange is not reached, his subscriber number is indicated at the switching station in the main installation when the so-called callback takes place, in the same manner as in the case of a subscriber point of the main installation (HA). The transmission of control data which is required in the context of the identification (which is to be carried out in this case) of the relevant subscriber point, and the transmission of the result data of the identification process take place via a specific line of the existing extension line harness (NAL). The said data are represented in coded form by AC voltage pulses at a frequency which is outside the voice band to be transmitted. For data protection, the data transmission is carried out at the same time via two permanently predetermined extension lines (NAL1 and NAL2). At the receiving end, the data transmitted in each transmission direction are supplied to a comparator (Vg) and are passed on to the subsequent functional units only if they correspond. If they are not identical, a repetition is initiated. <IMAGE>
