Patent DE-2753985-A1 (DE)
Title: Pneumatic displacement measuring appts. - has ring restraining pipe whose position is monitored by air flow through nozzle adjacent to surface
Inventor: NAKADA TETSURO
IPC: G01B13/08
Filed: 1977-12-03
Abstract: The inside face of the ring-shaped element (1) is fastened at a point (3) to the tube. A nozzle (4) extending through the ring-shaped element emerges on the inside face of the element at a point diametrically opposite the point where the element is fastened to the tube. A pressure sensor (7) connected operatively to the nozzle detects the pressure of the gas flowing through the nozzle. An alarm mechanism can be connected operatively to the pressure sensor which measures the throughflow rate of the gas streaming through the nozzle.

Title: Brake antiblocking system - has electronic evaluator comparing intervals between pulses from emitter on wheel
Inventor: PEUKER KARL ING GRAD
IPC: B60T8/1761
Filed: 1978-01-13
Abstract: The system controls a brake locking prevention system, particularly for motor vehicles, having an impulse emitter on one or more wheels to monitor its movement. To determine any tendency to lock, an electronic evaluation and control unit (5) measures the time intervals between the individual impulses. This uses the latest measured value as a basis for a subsequent theoretical time interval corresponding to maximum vehicle deceleration without locking tendency, and compares it with the actual duration measured for the next interval.
Patent DE-2804102-A1 (DE)
Title: Electro-mechanical filter with parallel bars and coupling wire - has torsion resonator bar with two constrictions symmetrically positioned w.r.t. centre
Inventor: TRAUB KARL
IPC: H04R17/08
Filed: 1978-01-31
Abstract: The electromechanical filter consists of parallel bender and torsion resonator bars, electrostrictive transducers, a coupling wire and at least one additional coupling element providing an attenuation pole. The torsion bars are formed as dumb-bells each with two constrictions (41, 42). The constrictions are located symmetrically about the centre. The distance (A) between the centres of the constrictions lies between 0.58 and 0.67 times the overall length (L) of the bar. The advantage lies in reducing the effects of production tolerance on effective mass and resonant frequency.
Patent DE-2804196-A1 (DE)
Title: Purificn. of exhaust gas obtd. esp. from power stations - via two stage scrubbing for effective removal of nitrogen oxide(s)
Inventor: HOELTER HEINZ
IPC: B01D53/60
Filed: 1978-02-01
Abstract: The parent patent described the single stage scrubbing of exhaust gas contg. SO2, HCl, HF, and NOx. In this addn. the improvement is the use of two scrubbers. In the first stage the gas is washed with a clear soln. of calcium chloride also contg. mono- or multi-basic carboxylic acids. After sepn. of the gas from soln., it is fed into a second stage into which a circulating liq. is sprayed; and liq. contains addns. such as (1) KMnO4; (2) urea; (3) hypochlorite; or (4) amines, etc. In the parent patent, SO2, HCl, and HF were removed with an efficiency of 99%, but only a max. of 70% of the NOx was removed. The present system uses a second stage in which the remaining NOx in the gas is removed.

Title: Deep hole drill rig - with drill collar dropping inside drill tube and contoured for hole deviation correction
Inventor: HENSBERG FRIEDRICH
IPC: E21B11/02
Filed: 1978-04-07
Abstract: A drill rig narrow-gauge holes to be drilled to great depths consists of a drill bit, made of cemented carbide or steel and connected by a press fit with the end of a tube. In-side the tube, a drill collar can be raised and dropped in quick succession by a thin rope to hit the rounded rear of the drill bit. The drill collar has a one-sided chamfer or recess at the upper end, and a spherical face, offset in the direction opposite to the chamfer, at the lower end. This is a low-cost rig which automatically corrects any tendency of hole deviation by the combination of a recess or chamfer with an offset hemispherical surface.

Title: Tone generator circuit for telephone systems - with phase and tone levels maintained as load level alters
Inventor: CEZANNE LOTHAR
IPC: H04Q3/00
Filed: 1978-05-17
Abstract: The generator circuit for the various tones is used to indicate the state of a call being made, i.e 'engaged' etc. in telephone exchanges. The load impedance at the exchange and the callers set is the same and the attenuation caused by connecting in further loads in parallel is compensated for by the maintenance of phase and levels between the different sources. A selector receiver is connected into the system in parallel with the internal connection group and with the line transformer associated with the callers line. This receiver provides the selection tone.

Title: Composite shuttering plate for moulding GFR concrete parts - composed of rubber-hinged strips with PTFE slack bands for accurate curving
Inventor: BUEHRER RUDOLF
IPC: B28B11/00
Filed: 1978-07-05
Abstract: Shuttering for mfr. of profiled, fibre-reinforced, concrete components is composed of a shuttering plate divided into hinged strips. The hinges allow selective swivelling of adjacent strips out of the plane of the plate and w.r.t. one another, forming a continuously curved surface between adjacent strips. A slack strip bridging the gap between any two adjacent shuttering strips is provided which allows the shuttering plate to be bent to achieve a concave curvature. The slack strip is tautened across its width when the intended curvature has been attained. Hinges are of rubber elastic material and ar evulcanised onto the edges of shuttering strips, whilst the slack strips are moulded from PTFE.

Title: Electronic fuel injection for IC engine - has frequency limiting circuit to allow for inertia of valve parts
Inventor: BENSCH GOTTHARD
IPC: F02D41/32
Filed: 1978-07-26
Abstract: A conventional system generates impulses (A) whose length and frequency depend on the engine fuel requirement. The impulses are fed (3) directly to an amplifier (9) and also to two frequency dividers (2, 4) in series. The outputs of the frequency dividers are combined with each other and with the original signal in two NAND gates (5, 6) to give two sets of pulses of the same length as the original impulses but at half and quarter the frequency. These are fed to the amplifier (9) which has a timing input (10) to select the highest of the input frequencies below the preset limit.
Patent DE-2834044-A1 (DE)
Title: Slipstream guide for lorry cab - has panel mounted to draw air over flat front and prevent soiling
Inventor: MICHELS HERBERT
IPC: B62D35/00
Filed: 1978-08-03
Abstract: The front vertical edges of the lorry cab are fitted with air scoops to draw air over the flat front to prevent build up of dirt on the front and on the windscreen. The scoops are simple clip on mouldings with wider intakes than exits to increase the air speed through them. The flow of air over the flat front of the cab forms a barrier to prevent road dirt and water spray from being thrown up onto the windscreen. The increased airspeed through the ducts also protects the sides of the vehicle from soiling.

Title: Vehicle security system with electronic coded key - gives alarm if doors are opened or if ignition is operated without correct key
Inventor: BETSCH HELMUT
IPC: B60R25/102
Filed: 1979-02-22
Abstract: When set to the 'alert' state, the vehicle security system gives an alarm if any of the doors are opened, even with a key, or if the ignition circuits are energised by any means. The system can only be switched to the 'passive' state by inserting a special coded key in the lock. The special key contains a circuit which generates a number of frequencies simultaneously, chosen from a wide frequency range, to form a combination. The key has contacts which mate with contacts in the lock to provide power for the key and transmit the combination to a detector. The system is switched to 'alert' by locking the door with the special key. A timer can be started, using the key, to permit servicing for a limited period using an uncoded pass key.
