Title: Telephone PBX's with logic circuits - include selector sets storing signals necessary for the connection build-up
Inventor: LOEWEN HARRY
IPC: H04Q3/62
Filed: 1974-01-31
Abstract: Logic circuits and selector sets are allocated to internal and external connecting circuits. To build-up a connection, only one free internal or external connecting circuit is offered to the calling extension by a clock pulse controlled extension scanner which cyclically scans extension information in extension stores, and suppresses interference factors on control and transmission paths by evaluation of gating pulses during a scanning period. It operates together with a connecting set scanner, which it controls. Alternatively, the extension and connecting circuit scanners are controlled by a clock pulse generator. All extension stores are connected in parallel for scanning by two common wires. The extension scanner controls scanning of the two common wires, and of switching relays.

Title: Dishwasher with overheating protection - has inlet and outlet pipes arranged so liquid always covers heating element
Inventor: MAGINOT WERNER
IPC: A47L15/42
Filed: 1974-02-22
Abstract: The dish washer comprises a housing with an inside container forming the washing chamber which on one side is shaped at the bottom to form a collecting trough to which is connected the pump for the water circulation. The water inlet opening for the circulating system in the collecting trough is mounted above the level of the heating element whilst the inlet for the waste or drainage system is mounted below this level so that the liquid level never drops below that of the heating element with the result that overheating cannot occur which would otherwise damage parts of the machine. The effective drainage level for the casing of the waste water pump is above the level determined by the inlet opening for the circulation system and is connected to the collecting trough at this height.

Title: Centrifuge for creating concn. determn. in biological matl. - in which all reagents are combined in single soln.
IPC: G01N33/70
Filed: 1974-03-26
Abstract: Simplified method for the determination of the creatine concn. in biological material, using a stock of Fullers earth suspension and all the reagents (MgCl2, NaOH and picric acid) combined ina single soln, the method involving use of a centrifuge vessel having a filter plug in its bottom opening and of a holder for this vessel for the collection of the filtrate. Gives a complete sepn. without the possibility of re-mixing after centrifuging. The centrifuge vessel has a conical lower part below which is a filter plug e.g. of cellulose or fine pore foam rubber with a narrow outlet for the filtrate. The outside is of stepped profile and fits into the holder vessel. Pref. after the first centrifuging the stock suspension is re-suspended in the sample e.g. serum for analysis, the liquid collected from the first centrifuging being collected in a crucible or liner and rejected. The liner is removed and the filtrate from the second centrifuge step is collected in the holder and treated directly with the reaction soln.

Abstract: The wind deflector is mounted at the front of the hole in the sliding roof. The deflector is hinged on a short lever with one end of the lever lonked to a set of two sliding levers which meet in the bearing block for the sliding panel. The ends of the sliding levers are provided with sloping faces to displace each other when the panel is slid closed, while the bearing block has a widened section inside so that the two ends of the sliding levers can slid over each other. The linkage enables a relatively large mechanical action to the provided at the end of the panel closing stage, so that the deflector is securely dropped into place. The sliding levers are arranged unobtrusively inside the profiled guide ducts of the panel.
Patent DE-2416939-A1 (DE)
Title: Sensor has cable sealed into housing with casting resin - and has radially-compressed metal ring as embedded retention piece
Inventor: SCHALLER WERNER DIPL ING
IPC: G01D21/00
Filed: 1974-04-08
Abstract: The sensor has its cable passing axially into its tubular housing. A metal ring wit a U-shaped cross-section encircles the cable and is compressed radially so that its innermost surface presses a tubular collar radially into the cable. The housing is filled with casting resin which forms a water-tight seal around the sensor and the cable. The radially projecting lips of the metal ring act as retention surfaces preventing the cable being pulled axially relative to the resin and thereby breaking the seal.

Title: Sensor system for detecting wetting of motor vehicle windscreen - uses light beam which is totally internally reflected when windscreen is dry
Inventor: KORNDOERFER BERND ING GRAD
IPC: G01N21/43
Filed: 1974-04-27
Abstract: A light source is placed on one side of a rectangular optical prism, and a photoelectric transducer on the other, so that by use of additional means, such as mirrors and lenses with a diaphragm, a parallel light beam is produced perpendicular to the prism cathetuses and spread if possible over the whole cathetus surface; it is reflected by total reflection from the outer surface of the tested glass plate, to whose inner surface the prism hypotenuse surface is cemented by an optical cement; the beam is partly diverted outward by wetting of the outer surface. Alternatively, two similar prisms with the same auxiliary equipment are used, so that the beam of light is reflected several times by the glass plate surfaces before it emerges from the second prism.

The two probes are so far apart that an interrogation level can be excited only in one probe even by the largest coin to be measured. The primary windings of the probes are supplied with a stable voltage at a stable frequency. The coin tester has a measuring, decoder and control circuit which cuts in or out alternately, according to the moving coin, the oscillators supplying the probes.
Patent DE-2429144-A1 (DE)
Title: Perforated plate for retention of solid particles - esp catalyst pellets in vehicle exhaust gas treatment devices
Inventor: WAGNER MELVIN HERMAN
IPC: B01J8/44
Filed: 1974-06-18
Abstract: A perforated plate for retaining solid particles has slots and lamellae which are integral with the plate and which are twisted about an axis lying in the plate so that one long edge of each lamella is straight and lies on one side of the plate and the other edge, which is curved lies on the other side of the plate. The plate is used as a gas permeable wall in a container for catalytic pellets used for emission control from engines. The plate has considerable rigidity and does not require welded-on stiffeners. The residual stresses from the forming operation are small and fatigue failures due to expansion and contraction are reduced. The slots/lamellae are formed in such a way and with such a dimensional relationship to the catalyst pellets that the latter lie tangentially against the surfaces of the lamellae rather than against their edges so that friction damage is minimised. The pellets are also unevenly spaced w.r.t. the slots ensuring that the open cross-sectional area for entry of the gas into the catalyst bed is evenly distributed.

Title: Office machines furniture with readily accessible cable ducts - has easily opened flap covering cables and plugs flush with work-top
Inventor: LAUERBACH RAINER
IPC: A47B17/00
Filed: 1974-08-12
Abstract: The office furniture which is particularly used for electric typewriters and other electrical equipment has a worktop and cable duct (1) which extends along the length of the furniture and is accessible from the worktop (2a) through a flap (3) lying in the same plane. The cables can be removed through a slit-like aperture (3) which is closed by a resilient seal (4) whilst the cable duct (1) is provided at its end sides with U-shaped apertures (5) in which the cables can be placed when the duct is open. Thus when the flap (2) is folded up the duct (1) and apertures (5) are freed so that the cables and plugs can be readily inserted.

Title: Optical fibre prepd. from the same material for core and sleeve - by altering the density and refractive index of the sleeve
Inventor: DESERNO ULRICH DIPL ING
IPC: G02B6/02
Filed: 1975-01-29
Abstract: Process for mfg. an optical wave guide fibre in which the core and the outer sleeves are made of the same matl., comprises altering the physical density of the sleeve so that the latter is optically diluted or weakened until the desired profile of refractive index is obtd.
