Title: Noise damping plug for water outlet - has air cushion sealed between two rubber diaphragms
Inventor: ZWINK HELMUT
IPC: F16L55/02
Filed: 1976-03-30
Abstract: A noise damping plug (1) is provided with an external thread (2) for screwing into the water outlet of valves etc. The plug (1) has a blind hole with a shoulder (3) which supports a diaphragm (5). The diaphragm (5) is clamped by a spacer ring (7), a second diaphragm (4), and a ring nut (6). The diaphragms (4, 5) are made of rubber or similar material and form two sealed air cushions (9, 10) inside the plug (1). These air cushions damp a wide spectrum of sound frequencies generated by the water flowing out of the valve in which the plug is fitted. The damping effect can be increased by increasing the number of diaphragms (4, 5).

Title: Card stacking and separating process - in which stamped cards are stacked on separating table during pallet exchanges
Inventor: VOSSEN FRANZ
IPC: B26D7/18
Filed: 1976-07-03
Abstract: The stamped or unstamped card sheets (2) are transferred to a separating table (1) and drawn by an overhead grip (3) to the stamping section. The table (1) moves downwards as the card stack becomes higher. The table can also move in a horizontal direction, as soon as the card stack (18) reaches a pre-determined height, to deposit the stack on a palette. Strips are provided to prevent the stack from tilting. The palette can be withdrawn and a fresh palette positioned while the machine continues to function. The new stack is supported by an unstamped card drawn from a supply stack (15Z) by a suction cylinder (13) and laid on the separating table as it reaches its horizontal maximum drawn out position.

Title: Automatic fluid level monitor for engine oil - eliminates dip stick using piezoelectric resonator controlling oscillator circuit
Inventor: SWEANY LOUIS PIERRE
IPC: G01F23/22
Filed: 1976-07-09
Abstract: An arrangement for the determination of fluid level is particularly applicable to oil level monitoring in the engines of lorries, school buses, or ambulances. The method eliminates maula inspection of conventional dip sticks which can be difficult for such engines. The device uses a piezoelectric resonator in a housing placed inside the oil container. The resonator is connected in an oscillator circuit contained in an external housing supplied from a battery. The oscillator circuit is connected to a display or indicator which may be a lamp. When the oil level falls sufficiently the resonator is no longer immersed in the oil and causes the oscillator circuit to oscillate. This causes the lamp to light. The device operates when the engine is not running.
Patent DE-2638966-A1 (DE)
Title: Thermal afterburner for IC engine exhaust gas - has two coaxial chambers, tangential entry to combustion chamber and turbulence baffles
Inventor: REICHEL KURT ING GRAD
IPC: F01N3/26
Filed: 1976-08-28
Abstract: The thermal afterburner for IC engine exhaust gas comprises a cylindrical outer casing in halves (2a, b) with lagging (5), cladding (4), and a tubular concentric inner casing (7) surrounding the combustion chamber (6). Gas enters this chamber tangentially through stub pipes (12, 13, 14) connected to the cylinder-head outlets; outlet ports (21) through which the gas flows into the space between the two casings before leaving by the (central) exhaust pipe (18, 19, 20) are located midway between the inlets. Scoops (26) formed by pressing inthe edges of the inner casing outlet openings, axially angled, augment turbulence in the chamber, as do axial (22) and peripheral corrugations. The casings are fixed together at one end, held concentric but free to expand at the other.
Patent DE-2641076-A1 (DE)
Title: Pulse width modulated data transmission - uses phase correction stage to ensure that modulator output is in form of symmetric series of 1 and 0 states
Inventor: AGRICOLA MANFRED DIPL ING
IPC: H04L25/49
Filed: 1976-09-11
Abstract: A pulse width modulated data transmission system allows a symmetrical output to be generated using phase correction. A fundamental clock signal of square wave form (GT) is transmitted to a 2:1 frequency divider stage (T), producing both true and inverted outputs (Q1, Q1). The complementary outputs are coupled to a phase correction stage (PKG) that outputs either of the inputs depending upon the feedback (SE1) from the modulator output (AD). The clocked character for transmission (ZL) is coupled over a data latch (DFF2) at a rate fixed by the modulator output (AD). The latch output is combined with the phase correction stage signal in a switching stage (US1). The circuit ensures that a symmetrical series of 1 and 0 states are generated, irrespective of the input phasing.
Patent DE-2649992-A1 (DE)
Title: Flashover-proof high tension capacitor - with plain plastic foil and offset metal strips on both sides of other foil
Inventor: VIERNICKEL KONRAD
IPC: H01G4/32
Filed: 1976-10-30
Abstract: A flashover-proof high-tension capacitor is wound from one foil with a metallisation on both sides, alternating with another foil with no metallisation. The metallisation on the two sides of the first foil consists of several parallel strips on each side, with those on one side offset relative to those on the other side and partly overlapping them. The metal strips are removed for a few man at the ends of the foil. The initial and final turns consists of a few layers of non-metallised foil. This eliminates edge flashovers because of the absence dangerous clearance across air. The mfr. technology is simplified and the capacitance is hedl to a finer tolerance because it is not affected by the foil run in the winding operation.
Patent DE-2653313-A1 (DE)
Title: Coke oven charging hole lid handling device - has articulated platform for height adjustment of turnable magnet and motor (NL 26.5.77)
Inventor: PRINS KLAAR

Title: Double use nappy - including pad which can be removed while nappy stays on wearer, and moisture absorbing main section
Inventor: GLASSMAN JACOB A M D
IPC: A61F13/15
Filed: 1977-02-05
Abstract: The main part of the nappy consists of a thick rectangular layer of material strongly moisture-absorbing and is combined with an oblong centre piece. Between these two layers, a third padding layer can be introduced, which also strongly absorbs moisture; it adheres to the main nappy. It is also longer than the centre piece of the main nappy. This fact makes it possible for the third part, i.e. the removable padding, to be removed from the nappy while it is being worn without having to remove the nappy from the wearer. As the main part of the nappy also consists of strong humidity resistant material, the nappy can be used twice without having to be removed and without having to remove clothing articles such as pants, as the removable pad will pull out from the other two layers without difficulty.

Title: Half tone images for e.g. synthetic leather or wood imitations - by transferring pattern from gravure cylinder to intermediate cylinder and then to a pressure cylinder
Inventor: MERTENS RUDOLF DIPL ING
IPC: B41F9/01
Filed: 1977-03-15
Abstract: In the prepn. of half tone images for e.g. synthetic leather or wood imitations by printing synthetic leather, PVC films etc. using a printing cylinder (I) suitable for intaglio printing and having a screen imaged pattern, the pattern being transferred after inking and wiping to the material running over a pressure roller (II), the process is characterised by embossing the material and transferring the pattern from (I) to an intermediate cylinder (III) with an elastic cover and from there to the material. The prints have a three dimensional appearance with improved reproduction due to softer lines and hazy contours.

Title: Sign indicator for rotating voltmeters - has optical chopper system using IR emitting diodes and IR sensitive diodes or phototransistors
Inventor: ROSS KARL
IPC: G01R29/12
Filed: 1977-03-23
Abstract: The rotating voltmeter with sign indicator for high-voltage DC measurements comprises a high-voltage electrode above a perforated, fixed cover plate. Between the fixed plate and a measuring electrode is located a rotating perforated chopping disc driven from a motor shaft passing through the base plate and measuring electrode. The exciter source for the optical chopper system uses an infra-red emitting diode. The photo-electric sensor uses a photo diode or photo-transistor sensitive to infrared light. These elements are housed in a light proof enclosure in the base of the rotating voltmeter assembly. This form of construction avoid amplitude modulation effects and the need for large motors associated with earlier types of sign indicators.
