Title: Thermography appts. using camera tube with moving target - of tri-glycine sulphate providing a flicker-free picture
Inventor: STUERMER WILHELM PROF DIPL CHE
IPC: H04N5/232
Filed: 1975-10-03
Abstract: An invisible radiation image is converted into a visible image using signals produced in a camera tuber by scanning, with which the brightness of a synchronised light spot is regulated and the taking section is changed. This change is converted to a signal and thus reprodn. of the change in the deflection of the light spot is avoided. The appts. consists of a camera and monitor, the camera mounted with a camera tube contg. a triglycine sulphate (TCS) target. Used esp. for converting IR pictures to visible pictures, e.g. in medical diagnostics. Since TGS targets tend to show troublesome charging effects and local heating, they must be moved to and fro or rotated. This methods give a stationary, flicker-free picture, utilising the charging etc sensitivity of the target. The camera tube is pref. rotatable and a potentiometer connected to the picture tube of the monitor is used to convert this motion into electrical signals.

Title: High amplitude swinging of centrifugal drum prevented - esp. in large capacity domestic washing and drying machines
Inventor: EHRIG GUENTER
IPC: D06F34/16
Filed: 1976-02-19
Abstract: The swinging due to imbalance of the centrifugal drum of a domestic washing and spinning machine is prevented from reaching high amplitudes by having the drum, in the period before acceleration to centrifugal speed, rigidly supported in its bearings. As the speed of rotation increases, the force of the imbalance is measured and, dependent upon the measurement, the speed of the drum is either lowered to a point below that at which the load of laundry items can rearrange itself, and then increased as from the start, or, is further increased finally to a rate of revolution above the critical figure for the unit, which is then changed over to running in flexible bearings. Eliminates excessive swinging due to imbalance, as well as the need for removing half the load before tumble drying commences. A larger size drum can be fitted without increasing the outside dimensions of the machine, and 4-5 kg of laundry can be washed and dried in a single run.

Title: Railway wagon position detecting system - uses transmitter on locomotive whose signal propagates along line conductor in both directions and two stationary receivers
Inventor: AFFOLTER PETER DR
IPC: B61L25/02
Filed: 1976-04-24
Abstract: The position detecting of railway wagons, using the railway line conductor, is carried out by transmitting a signal from a sensor mounted on the locomotive. The signals propagate in the line conductor in both directions and are applied to two stationary receivers. The position of the locomotive relative to the receivers is determined from the time difference between reception of the signal in both receivers. The determination is carried out by computers. Pref. a simple line conductor is used, and the transmitter sends out a pulse train at present time intervals to the receivers at different positions. A constant signal propagation velocity may be used in the line conductor over the entire path, the position determination being dependent on the time required for the pulse train reaching the two receivers respectively.

Title: Closed cycle turbine engine - has intake combustion air heated by closed cycle working medium
Inventor: VESTER GERHARD
IPC: F02C1/10
Filed: 1976-07-19
Abstract: The turbine and compressor impeller are enclosed in an endless acceleration tube filled with an inert gas or liquid such as water air helium or sodium. The turbine and compressor impellers are fitted to coaxial shafts. The main shaft extends through the accelerator tube to carry the starter motor or (20) and a belt pulley for the combustion air intake fan drive as well as provide output energy. The accelerator tube is surrounded by a heat insulated combustion air tube (10). The air tube widens out to form heater tubes and terminates. An exhaust pipe leads the combustion waste to atmos. The endless acceleration tube upper surface is increased by cooling ribs to act as a heat exchange between incoming combustion air and working medium. Combustion takes place in an annular combustion chamber (2) and heat is deflected by a shield (3) on to the inner heater tubes in the accelerator chamber (4). The medium leaves the chamber via the first turbine impellers (5) which turns the shaft driving the compressor (6). The compressor draws the working medum from the final turbine impeller to commence a cycle through the accelerator tube.

Title: Underground cable fault locator using induction - has HV generator modulated by audio tone to aid detection by prodn. of spark discharge at fault
IPC: G01R31/08
Filed: 1976-11-12
Abstract: The underground cable fault location system is suitable for cables both with and without exterior metal sheathing.
