Title: Perceivable traffic signal display on flexible foil - consists of housing with window and rollers for foil with adjustable braking force for drive
Inventor: LAUENROTH WOLFGANG
IPC: G09F11/29
Filed: 1976-02-03
Abstract: In order to display a required traffic signal, rollers are driven by an electric motor. Signal foil (4) is wound on transport rollers (5a,5b) at a distance from each other. One reel is connected to the drive (14a,14b) through an electronic control circuit (10), while at the same time a brake (16a, 16b) is applied to the other roller. The rollers (5a,5b) are mounted in a frame. The coupling for the brake units is applied by electromagnetic means and the braking force is adjustable. The motor drive is applied through a toothed belt (13) directly to the transport roll, which is in turn linked to an idler roller by a chain link drive (15).

Title: Reducing noxious emissions in acid pickling plants for metals - by injecting controlled amt. of steam into air above pickling bath
Inventor: ULLRICH HANSJUERGEN DIPL ING D
IPC: B01D53/34
Filed: 1976-02-18
Abstract: The emission of noxious substances is reduced in plants used for the pickling of metals with acid in an enclosed bath fitted with controlled fume extn. Steam is blown into the air space above the pickling bath inside the plant. The amt. of steam employed pref. provides a partial pressure equal to the vapour pressure provided by the surface of the bath or on the wet surfaces of the workpieces. Alternatively, the partial pressure due to the steam may be above the vapour pressure provided by the bath surface or the wet workpieces. The process can be used, e.g. when metals are pickled with HCl or HNO3, where fumes of HCl or NOx are obtd. The invention can be applied to almost any modern plant using pickling tanks which are enclosed so they can be provided with fume extn. plant.

Title: Motor vehicle town piloting system - has recorder selecting appropriate section of selected town tape from coordinate data of start and destination keyed in by driver
Inventor: BECKER GERHARD DIPL ING
IPC: G09B29/10
Filed: 1976-10-15
Abstract: The vehicle piloting system consists essentially of a tape recorder with a tape for the town which is strange to the driver, a map of the town and a transparent co-ordinate network fitting on top of it. The driver lays the latter over the map and reads the co-ordinate of his starting and destination points. The co-ordinate information is typed into the recorder by a keyboard. The recorder then runs through the appropriate tape section to give the driver the best route. If the route is a long one, the system deals with it by sections. From the starting point it gives as first destination the point in the first section closest to the driver's selected destination. It then carries on from there to the next nearest point of the next section until the final destination is reached.

Title: Cylindrical counterflow multi-fan cooling tower - in which water to be cooled flows downwardly in counterflow to rising air
Inventor: BODICK GAYLORD E
IPC: F28C1/00
Filed: 1977-10-28
Abstract: Cylindrical counterflow multi-ffan cooling tower has a cylindrical cold water basin and a cylindrical shell spaced above the basin. A deck is supported above the shell and a plenum chamber is defined in the shell between the deck and the fill system. Water from a distribution system in the plenum chamber above the fill distributes water downwardly over the fill in counterflow relation to the air drawn up through the fill. Fans on the deck draw air through the space between the cold water basin and the shell through the fill system and plenum chamber and discharge it as a high rising column of hot moist air. The cylindrical configuration of the tower, as opposed to the usual rectangular configuration, results in improved cooling efficiency because the tendency of the hot moist air to be drawn back into the tower when a strong wind blows is reduced.
Patent DE-2748775-A1 (DE)
Inventor: GRUDZINSKI RICHARD
IPC: F16H27/02
Filed: 1977-10-31
Abstract: The present invention has as an object the provision of an electromechanical analogic display device for electronic chronometers, comprising at least an electromagnetic motor controlled by an electrical impulse of short duration. The attractive influence of the latter distorts a spring, very rapidly storing the produced energy to release it in the form of kinetic energy and driving a toothed wheel coupled to the analogic display while on the other hand this electromagnetic motor activates a locking system permitting the passage of a single tooth per cycle, and thus assures for said device immunity from mechanical shocks and most particularly from tangential accelerations.

Title: Assembling glazed window frames - using viscous sealing material in channels as bedding for glazing with outflow checks
Inventor: KNIGHTS RICHARD NORTHAM
IPC: E06B3/56
Filed: 1977-12-15
Abstract: Process for making a window frame involves assembling a series of frame pieces (a), with an inwardly facing channel in them for fitting onto the pane (12). A viscous sealing substance is introduced into the channels, to combine sealing effect with provision of a bedding for the pane edges; and there are devices for preventing or checking outflow of superfluous sealing material. The initially viscous substance may subsequently become firmer, retaining some elastomer qualities. Further sealing material may be introduced at the frame edges. Double glazing may be effected, with an edge spacer between the parallel panes. This obviates any need for a special sealing strip, and assembly of glazed frames is semi or fully automatic.

Title: Car radio with level compensation for vehicle noise - has delayed response to vehicle noise detected by microphone to avoid responding to transient noises
Inventor: BOETTCHER PETER
IPC: H03G3/32
Filed: 1977-01-27
Abstract: The motor vehicle radio receiver has an integral circuit which increases or reduces the output sound level according to the noise level in the vehicle at any particular time. Compensation is based on a feedback circuit driven from a microphone picking up the vehicle noise. This feeds and amplifier and delay circuit whose output after smoothing is fed into the bass frequency channel of the receiver. A delay circuit prevents response to transient noise and is based on a capacitor driven from a ransistor constant current source. A switch having a non-linear operating characteristics provides a threshold leel at which the delay comes into operation.
