Title: Telephone exchange test desk circuit - distinguishes between on-hook and engaged conditions by comparing voltage drop across measuring resistor with threshold value
Inventor: WAGNER KARL
IPC: H04Q3/00
Filed: 1977-07-15
Abstract: The voltage drop across a measuring resistor as evaluated by a voltage measuring device is, when a tested circuit is free, above a threshold value and is, when the circuit is engaged, below the threshold value. In the event of a circuit being tested simultaneously by two testing devices the voltage drop is likewise below the threshold value. For closing a circuit found to be free and monitoring for opening of the circuit the resistance value of the measuring resistor and the threshold value are both reduced. One and the same circuit serves for testing for the free state of a circuit and also for recognising the disconnection of the circuit following its closure.

Title: IC engine afterburner combustion chamber - has metal tubes prolonging passages in ceramic plate on discharge side
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/26
Filed: 1977-09-07
Abstract: The gases leaving the combustion chamber of the afterburner pass through a perforated ceramic plate (18) and impinge on a metal baffle plate (8). This turns them through a right angle and absorbs heat from them. An intermediate metal plate carries metal tubes (3) which prolong the passages (9) in the ceramic plate (18). A cooling medium flows round the metal tubes in t"h space (15) between the end of the ceramic plate and the intermediate metal plate. There is a further colling channel (5) at the back of the baffle plate (8). The construction increases the cooling of the gases discharged from the afterburner.

Title: Optical method of dimensional measurement - uses radiation source, mobile deflector and receivers to determine cross-section
Inventor: PIRLET ROBERT ALFRED
IPC: G01B11/02
Filed: 1978-03-08
Abstract: An optical technique is described for measuring the dimensions of an object, in particular the dimensions of the cross-section of formed sections coming from the rolling mill. A beam of radiation (9) is directed onto the object (2) and the orientation of the radiation is modified using a mobile deflector (4), thus ensuring that all points of the object (3) are scanned in relation to the dimensions to be measured and also that the optical 'circuit' formed by the transmit and receive axes is flat. The re-transmitted beams (10) from the various points of the object (2) are kept in the field of observation of one or more linear receivers (6). The required dimensions are determined using the indications provided by the position of the deflector and by the receiver. The receiver field of observation may be increased by using a number of receivers positioned side by side so that their fields of observation are contiguous.

Title: Automatic on=off power switching circuit for extension telephone - has second switch triggered by ringing signal to operate blocking circuit
Inventor: ROEPKE WILHELM
IPC: H04M19/08
Filed: 1978-03-11
Abstract: The switching circuit has a switch for the power supply which closes when the telephone set's handset is lifted- or closes by means of another method of initiation- and allows current to flow from the exchange battery directly or indirectly. When the handset is replaced, the switch opens again & the current is discontinued. A second switch is triggered by the flow of ringing current and operates a blocking circuit that either blocks the supply or releases it. A delay circuit delays the supply's disconnection for a given time after the exchange battery's current has been interrupted.
