Patent DE-2604334-A1 (DE)
Title: Exchangeable measurement cartridge in flowmeter - is supported in plastics case sealed by discs at ends with projections and slots
Inventor: HAHNER GERD
IPC: G01F1/06
Filed: 1976-02-05
Abstract: The cartridge is sealed in the case by two closing discs. The discs are screwed into the inlet and outlet ends and they are sealed by projections and slot a parallel to the cartridge axis. They are inserted between the case and cartridge. Cross-sections of sealing projections and slots are not identical but they are so adapted to each other, that they are in contact with each other along sharp edge-like contact lines. They are deformed by the pressure of the screwed-in discs so that they form well sealing contact strips.

Title: Push button switch with contact springs in socket - has contact springs in parallel to wedge:shaped push button shift direction
Inventor: BERGINSKI WERNER ERNST
IPC: H01H13/12
Filed: 1976-03-13
Abstract: In the push-button switch socket are mounted two contact springs (4, 5) parallel to each other and to the shifting direction of the push-button (3). The latter has a wedge-shaped switching profile (23). Each contact spring abuts one push-button wedge surface (24, 25). On depression of the push-button the contact springs are deformed against their prestressing force. Preferably the wedge angle is greater than that under which the contact springs are prestressed. Each contact spring may be mounted integrally with a flat connecting plug (27) whose folded-over may form a clamping strip (28) which engages a latching recess (13) of the socket.

Title: Antislip mat for carpets including plastics grid - has groups of short points on its upper surface with long points on underside
Inventor: KEMPE WALTER
IPC: A47G27/04
Filed: 1976-04-30
Abstract: The antislip mat for carpets consists of a plastic grid with strips running lengthways, crossways and diagonally over the mat. At the crossing points between the strips are, on the upper surface, groups of short points (6). These points are also at the centre of the length and gross strips. At the same points on the under side are, a number of long points each groups having one long point beneath. The upper surface in other variations can also be covered entirely with short points, or the groups of points can have interspaced a number of slightly longer points. By use of this mat between the carpet and othe fllor, the carpet cannot ride along the floor.
Patent DE-2620006-A1 (DE)
Title: Light chopper for photometer - has rotor with axis transverse to light beam giving improved mechanical stability
Inventor: BERTHOLD RAINER DIPL PHYS
IPC: G01J1/36
Filed: 1976-05-06
Abstract: An electromechanical device for modulating radiation, esp. for a photometer, comprises a revolving member (chopper) comprising apertures through which the light can intermittently pass, the chopper is driven by an electric motor. The chopper comprises >=1 shaft contg. >=1 aperture passing through it transversely to its axis, the direction of the radition is transverse to the axis. Thus, as the shaft(s) revolve, the light beam(s) is/are intermittently interrupted. For a single-beam device, a single shaft possesses one aperture passing through it. For a two-beam device, the shaft possesses two apertures, offset by 90 degrees to each other, this arrangement produces phase-displaced but synchronous modulation. A single shaft may possess one aperture in one region and a succession of apertures in another region, giving two different modulations of the light. Used for either single beam or two-beam modulating devices. The two-beam device spplies a reference beam and a measuring beam and eliminates zero point drift, operating selectively to the modulation frequency, thus limiting the band width and reducing noise, and of suppressing disturbances caused by scatter. In addn. variations in light intensity caused by mechanical instabilities can be reduced to values as low as 10-5 per week, which is two orders of magnitude lower than the variations of 0.1 - 0.2% obtd. with more conventional choppers.
Patent DE-2625155-A1 (DE)
Title: Safety flashers for public transport vehicle - has lights with power supply linked to vehicle alternator output to be operated when door is opened when engine is running
Inventor: SCHNAUSE ROLF
IPC: B60Q1/52
Filed: 1976-06-04
Abstract: The vehicle doors are fitted with switches linked to a flasher safety control. This operates the hazard flashers, or roof mounted indicator, when any door is opened. The supply for the flasher circuit is linked to the vehicle alternator output so that the flashers only operate when the engine is running. The system provides a safety indicator for busses, esp. school busses, with the flashers operating at the pick-up points. The flashers do not operate when, at the end of a route, the driver opens the doors to clean the vehicle.

Title: Offset printing machine with plate treatment unit - has printing cylinder surface sensitised each time to create new images
Inventor: HELL RUDOLF DR ING DR ING
IPC: B41L17/12
Filed: 1976-09-04
Abstract: Offset printing machine has a printing cylinder whose surface has its water attraction and rejection properties varied by suitable radiation using e.g. illumination (2) and sensitisation units (3). A damping mechanism (4) and inking mechanism (3) are provided. The ink image is transferred to a blanket cylinder (8).

Title: Electromagnetically operated transducer for road traffic counting - is mounted in road surface and generates pulses when vehicles cross it
Inventor: RICHTER JOACHIM ING GRAD
IPC: G01L1/14
Filed: 1976-10-23
Abstract: A simple electromagnetically operated transducer for counting vehicles is mounted in a groove in the road. It generates voltage pulses when vehicles cross it. Two magnetically conducting rods are mounted horizontally in a groove in the road, separated by a number of permanent magnets (1) with flexible spacers and pickoff coils (5) wound round the magnet elements. When a vehicle crosses this, the flexible spaces are compressed, altering the magnetic reluctance of the circuits and corresponding pulses are generated in the coils. Alternative forms of the device use separate pickoff cores and magnets (1). There are also arrangements using a flexible upper rod and spacers under only some pickoff core elements and magnets.

Title: Fuel pressure regulator for IC engine - has orifice control plate moved laterally to vary pressure of fuel
Inventor: PERR JULIUS P
IPC: F02D1/12
Filed: 1977-07-13
Abstract: A pump (17) delivers fuel from a tank (11) to an engine intake (19). A continuous flow is maintained between the pump outlet and a return (38) to the tank through a pressure regulator (37) which maintains a constant pressure at the engine offtake (19). Fuel enters the regulator through an opening (34) in the lid of a chamber (36). A plate (41) is pressed against the opening by a spring (43) and the fuel pressure depresses the plate against the spring. The plate has a recess (62) facing the opening. The effective area on which the fuel pressure acts depends on the extent to which the recess overlaps the opening (34) in the cover (32). This is varied by lateral movement of the plate by a diaphragm (58) which responds to engine suction pressure.
