Title: Display of signal quality received by radio controlled clock - compares second timing impulses with reference level to drive visual indicator
Inventor: HILBERG WOLFGANG DR ING
IPC: G04R60/00
Filed: 1980-04-21
Abstract: If the quality of the signals received by a radio controlled clock is insufficient to operate the clock circuits accurately the time required to produce a correct display can be long. In order to indicate the reason for failure to achieve a correct or full display the received signal strength and quality are compared with a built in reference. The result is then indicated on the clock. The seconds signal is employed for this evaluation. The display may take the form of a visual plus sign on the clock to show correct signal level, and minus for a defective signal state. The indicator may be controlled by a manual switch so that the signal state can be checked when the clock is in operation. Used in this way it is possible to check whether the clock is in synchronism with the transmitted signals or is running autonomously in the absence of satisfactory signals.
Patent DE-3017579-A1 (DE)
Inventor: BADE JUERGEN DIPL ING
IPC: H04Q3/00
Filed: 1980-05-08
Abstract: The invention concerns a circuit arrangement for telephone exchange systems, to block the outputs of one or more selection stages (K1), which are connected to the inputs of a following coupling arrangement (K2), using a full load signal (VL) which is generated if a device which follows the coupling arrangement (K2) cannot be reached. Blocking devices (Sp1 ... Spn) are connected to all testing wires (ce1 ... cen), which devices in case of full load, and after the relevant selector output has been triggered, apply blocking potential (OV) to the relevant testing wires, even before the testing relay (P1 ... Px) has responded. If this is used in line concentrator devices, the result is that if the called subscriber is free, but all the principal lines (L1 ... Lz) are occupied, the line selector (W1 ... Wx) sends the busy tone and busy code. <IMAGE>

Title: Waste water cleaning system - with water jet pump in first section of sectionalised tank
Inventor: STOG WILHELM
IPC: C02F3/12
Filed: 1980-06-07
Abstract: Waste water is purified in a tank which has been subdivided by vertical partitions into sectors which the water has to traverse in a meandering flow path. A water jet pump which is arranged in the first sector near the inflow injects a water-air mixture through a diffuser in a direction opposite to the inflow of the waste water. This ensures a long contact between liquid and air bubbles and prevents any premature coagulation of the fine bubbles.

Title: Automatic dispenser for e.g. cash, cheques - has tiltable platform positioned within chamber forming purge device associated with microprocessor
Inventor: GUIBORD RONALD D
IPC: G07F19/00
Filed: 1980-12-09
Abstract: The banknote dispensing system includes an operator panel having a keyboard for initiating transaction requests, and a dispensing chamber (58) adjacent to the panel for receiving banknotes dispensed by feeders (52) and a transporter (54) in response to an operator request. A lockable access door (40) enables the operator to gain access to the chamber to remove dispensed notes. A tiltable platform (60) positioned within the chamber forms purge device for discharging dispensed notes from the chamber under predetermined purge conditions detected by a microprocessor within the system. The microprocessor calls for a purge operation when it has been determined that the operator has either failed to remove dispensed notes or has left notes within the chamber. A purge operation may also be performed as a result of a system failure, such as a power outage or a counting error occurring during a dispense cycle; or when a foreign object is detected in the dispensing chamber as a result of vandalism.

Patent DE-3110162-A1 (DE)
Inventor: DOMMER ARMIN
IPC: B29C65/00
Filed: 1981-03-16
Abstract: Device for butt end welding of pipes and/or parts of synthetic material according to the thermal element welding method. With such method it is important to bring the synthetic material parts, after plastification of the binding surfaces, into a pressing position where the increase of pressure up to the pressing value must follow a given time-pressure curve so as to obtain a perfect welded joint. According to the invention, this is echieved due to the fact that the reverse valve connects, in its open position (AS), at least the conduit under presssure (DE) of the pump (HP) with the control conduit opening into the working chamber (AK) of the hydraulic cylinder, that to the conduit under pressure are permanently connected one accumulator (DSp) and a manometer (MA) with an interruption switch (mk) adjustable to the desired pressure value, and that the electric motor (M) of the pump may be switched on by means of an additional push button (TS) and switched off when the pressure reaches the predetermined value.

Title: Film-welding device for welding and severing household film bags
IPC: B31B50/99
Filed: 1981-05-20
Abstract: A film-welding device for welding and severing household film bags of thermoplastic material, in particular for packaging frozen goods, has a support bar provided with an electrical heating apparatus and a pivotable pressing bar interacting with said support bar. Between the heating apparatus and the pressing bar a film web folded in two layers can be unwound from a roll accommodated in the device housing. For the reliable welding and simultaneous severing in only a single operation of the film web which is taken off from a roll and joined to form a bag, the heating apparatus has at least two heating conductors arranged at a distance from and parallel to one another, of which one heating conductor is provided for welding and the other heating conductor for severing the film web. Instead of two heating conductors, the heating apparatus may also have three heating conductors, by means of the two outer heating conductors of which the film web (14) can be welded and severed by the central heating conductor thereof. By this means, in the case of the subsequent film strip taken off from the roll, one lateral seam is already welded.

Title: Electronic momentary-contact switch which is dependent on a mains power supply
Inventor: STETTNER GERHARD ING GRAD
IPC: H01H21/22
Filed: 1981-07-25
Abstract: In the case of a momentary-contact switch (key switch) having a plurality of pushbuttons (4), which are located side by side, for selecting different rotation speeds of an electric motor, especially in domestic slicers (cutting machines), it is intended that the machine also be connected to the mains power supply at the same time as a specific speed is selected.

The momentary-contact unit (1) has a microswitch (5) allocated to it. If a pressure force is exerted on one of the pushbuttons (4), then not only is the associated switching path operated, but the momentary-contact unit (1) is also pivoted against the force of the spring (3), as a result of which the microswitch (5) is closed and the main circuit is connected to the mains power supply. <IMAGE>
