Title: RC active fourth-order band-pass filter - has input signal passing via two RC three port networks of second order to operational amplifier
Inventor: NOSSEK JOSEF DIPL ING
IPC: H03H11/12
Filed: 1978-02-28
Abstract: The fourth order bandpass filter applies the input signal (1) separately via two RC three port networks (NA, NB) to the two inputs of an operational amplifier (11) whose output is connected to the filter's output terminal (2). Both RC networks are second order and cover different frequency ranges. The first ports of both networks are connected to the input and their second ports directly to the operational amplifier's output. Their third ports are coupled to the amplifiers inputs. The advantage lies in the relatively few capacitors needed in the filter.

Title: Coating glass bottles with lacquer or plastics - where coating prevents the formation of dangerous splinters if breakage of bottle occurs
Inventor: DANIELS MANFRED DIPL PHYS DR
IPC: B05D3/04
Filed: 1978-06-03
Abstract: The bottles are rotated on their axes of symmetry while they are conveyed underneath one or more spraying nozzles covering the external surface of the bottles with the liq. The bottles next travel through a hardening or conditioning zone in which the liq. sets or is cured. The pref. plant includes an endless conveyor chain fitted with a row of heads; and the neck of one bottle is inserted in each head. The heads are then rotated while the conveyor chain passes under a row of reciprocating spraying chambers, each possessing a row of nozzles covering the bottles with the liq. One or more adjustable dosing pumps feeds the liq. into the spraying chambers; and the coated bottles then travel through a hardening or curing oven. The bottles are to be filled e.g. with CO2 which causes dangerous splinters to fly in all directions if the bottle is broken while still full. The invention provides a simple and rapid method of forming a uniform protective coating on bottles.

Title: Floor mop with detachable head - has forked holder and spring biased retaining wires holding handle firm without further aid
IPC: B25G3/12
Filed: 1978-06-12
Abstract: The floor cleaning mop has a pair of fork arms (2) attached to the end of the handle to fit into holes (4) in the brush head (5).

These wires adjoin the lower shorter end of a double lever (10) mounted between the fork arms whilst the upper longer end of the lever acts as a pressure plate. Since the spring wires are held hooked in position through their own spring tension further locking is no longer required. The connection can be readily released by applying slight thumb pressure to the pressure plate of the double lever.

Title: Cleaning solvent recovery - uses a cold bath in the path of the recirculating drying air
Inventor: BIESINGER ERWIN
IPC: D06F43/08
Filed: 1978-12-19
Abstract: To recover solvent from the drying air in a dry cleaning equipment, the recirculating air is passed through a bath filled with a fluid held 0 degree C.

Title: Swivelling warning board allowing one way traffic - has bottom spikes to pierce tyres and return mechanism operative after swing
Inventor: WISSIG ADOLF ALBERT
IPC: E01F13/12
Filed: 1980-02-05
Abstract: Passage is permitted in one direction, and prevented in the other, by a swivelling board affording warning to motor vehicles, with telescopic layout and resilience for lowering to road level and springing up again. The underside of the board (16) has nails (20) for penetrating vehicle tyres. On one side it can swivel through 180 deg. so that a vehicle coming the other way causes the underside to turn upwards. When swung through 180 deg. it is returnable to its initial position by a return mechanism (28,32). Vehicles approaching from the wrong direction are forcibly stopped, and the board then returns so that the action can be repeated.
