Title: Radio warning system for road traffic - has sender receiver in each vehicle with automatic and manually operated alarm code signals
Inventor: WEISS WOLFGANG R DIPL ING
IPC: B60Q1/52
Filed: 1975-12-30
Abstract: The radio system is intended to warn the driver of unexpected obstructions on the road, in particular a sudden build up of traffic or danger situation such as fog, poor road conditions or road works. As many vehicles as possible are fitted with senders or receivers with low range coded signal transmission capability. The set sends warning signals to other vehicles automatically or manually. A retardation sensor is in each vehicle to actuate a warning signal when brakes are applied suddenly. The hazard warning lights can also generate a signal. The warning signals can have frequency or amplitude modulation or can be pulsed to five a series of different sounds. The apparatus requires its own antennae and an independent battery power source.

Title: Spiral fluted thread tap - has teeth set back to form stepped chip groove at core height
Inventor: FENGER PETER
IPC: B23G5/06
Filed: 1976-02-10
Abstract: The tap flutes are right-handed, and in the guiding portion, beginning after the first full tooth, the teeth are stepped back at the height of the core diameter, so as to form a stepped chip groove. The step in the teeth can be either parallel to the chip groove, or not parallel, due to two spirals being superimposed on each other, their intersection point being shortly behind the initial cutting point. The rake angle is always positive. The tool is so designed that the shape of the machined off chips of metal is such that clogging up is prevented during use.

Title: Drive for rotary capacitor - has two bevel wheels one of which is formed of plastics to mesh with other without play
Inventor: HENNINGER HELMUT
IPC: F16H57/022
Filed: 1976-09-10
Abstract: Both wheels (1, 2) are fitted with the aid of a spring ring (5) on separate shafts (3, 4). The first wheel (1) comprises a hub (6) to which a ring fillet (7) connects. This fillet (7) carries a toothed crown (8) which is in engagement with the teeth of the second wheel (2). The first wheel is of flexible synthetic material. The two shafts (3, 4) are so adjusted relative to each other, that the first wheel (1) is slightly tensioned, thus causing the wedge-shaped teeth of the toothed crown (8) to be pressed into the correspondingly formed teeth of the second wheel (2). Thus excludes any play between the teeth.

Title: Electrolysis system for oxidation reactions - using extended surface electrode formed by conducting particles in cell
Inventor: AGLADSE RAFAIL ILJITSCH
IPC: C25B1/28
Filed: 1976-12-07
Abstract: Electrolysis system for manufacturing chemicals are housing round which an electrolyte is circulated. Inside is a particulate electrode with insoluble conductor lines. Means of removing sludge and electrolysis products are provided. The particles are made from an electrically conducting material. The housing has electrically insulated walls contg. the particles into which are mounted the insoluble conductor lines. In contact with the electrolytes, the particles form layers of reduced conductivity. When a potential is appled to the conductors, this creates a bipolar effect on each of the particles. the housing is of reduced dia. in its upper section causing an acceleration of the electrolyte upwards propelled by the gas generated during the process. One of the conductors can be movable. Used with electrolytic processes making oxidising agents such as permanganates, dromates, dichromates and of Cl-O cpds. such as chlorates and hyporchlorites. Provides a compact electrolyser of high capacity which operates like a number of individual baths linked in series. A strong current can be applied to a large electrode surface on the particles, and use is made of a bipolar effect.

Title: Abrasion-resistant protective coatings on concrete, etc. - of fibre-reinforced resin sheets applied with adhesive (OE 15.5.77)
Inventor: FESSLER HELMUT
IPC: E02D31/06
Filed: 1977-05-02
Abstract: Protective coatings for structural components exposed to abrasion or caviation, esp. in hydraulic applications, consist of sheets of synthetic resin reinforced with glass fibres or similar, and stuck in place with an adhesive layer. The sheets can be made under optimum conditions, e.g. from heat-hardening epoxy resins, giving better properties than cold-setting liq. compsns. applied directly to the structure. Sheets of any required thickness can be applied to vertical surfaces in a single operation, with no problems of adhesion between multiple liq. coats. The bond is unaffected by moisture in the substrate or exposure to frost and thaw. Damaged areas can be readily replaced.

Title: Pressure measuring cell in insulating housing - has piezo-resistive device to convert fluid pressure changes to voltages
Inventor: PFEFFER JOSEF
IPC: G01L9/00
Filed: 1977-06-10
Abstract: The cell (1) consists essentially of an insulating housing (11) in which is mounted a membrane (16) to which a piezo-resistive element is attached. Lead wires (20, 21) complete the electrical connection between the piezo device (17) and terminals (18, 19) in the housing. The two components of the housing (12, 13) are closed by a seal (14), and, together with the membrane define a pressure space (24) which is vented through an opening (15) to a fluid conduit (4). Changes of oil level in the conduit cause changes of pressure at the membrane and are manifest as changes in the output voltage from the transducer. In an alternative embodiment, the piezo-transducer is actuated indirectly by means of a spring device.

Title: Stimulation and reaction detection equipment - uses signals generated automatically to programme controlling stop-watch and sound tapes
Inventor: IRMISCH ARNDT DIPL ING
IPC: A61B5/16
Filed: 1977-07-05
Abstract: The equipment provides stimuli and detects verbal and physiological responses and reaction times. The stimulus is initiated by a starting signal, followed by others automatically generated as the previous responses and times are detected and the response values reach a set degree of constancy. The detector units are prepared by an activation signal as each stimulus signal begins. Acoustic stimuli are supplied by a programmed tape started by the initiation signal. By means of a first amplitude discrimination circuit, time-lagged if necessary, for the audio signal or a synchronous frequency control signal on an additional track, start and finish of the stimulus are detected and converted into signals, the start signal forming the activation signal. This and the end signal control a digital electronic stopwatch. The end signal also activates a second amplitude discriminator circuit, time-lagged if necessary, and stops the tape.

Title: Pointer knob for rotary controls - uses keyed disc which fits over control shaft flat
Inventor: RAUPACH GERHARD
IPC: H01H9/16
Filed: 1977-09-07
Abstract: The pointer assembly is designed to provide a clear, unambiguous indication of the setting of a rotary control, such as a potentiometer. The device is for use with control shafts having a flat. The shaft of the control projects through a front panel (11, 12) which has a number of graduations (14).
