Title: Drying of wheat gluten - by passing through cutter mixer with dried particles into flash dryer
Inventor: FEMERS KURT
IPC: A23J3/18
Filed: 1978-03-20
Abstract: The Parent Patent described the thermal treatment of sticky materials, esp of wheat gluten in a flash dryer by hot air in concurrent or counterflow.

Title: Electric steam iron - with contoured water guide plate subdividing evaporator chamber and separating steam
Inventor: RADER ARMIN ING GRAD
IPC: D06F75/18
Filed: 1978-12-02
Abstract: The evaporator chamber receives water through a drip valve and is divided by a contoured water guide plate into several systems of channels which communicate with each other through holes and nozzles. The nozzles leading into the final steam outlet cavities are curved to a dome shape so that no water can be carried over with the steam. All parts of the channel system are coated with a lining which prevents the deposition of scale. The iron has a high steam capacity and can be used with normal tap water without any softening plant. If any descaling becomes necessary, the bottom plate and the water guide plate are readily accessible so that any incrustation can be readily removed.

Title: Radio linked security alarm system - has remote display which can be set by patrols and uses different local and remote frequencies
Inventor: KOEHN JOHANNES
IPC: G08B25/00
Filed: 1979-04-03
Abstract: Security of an establishment is monitored by a number of burglar alarm units which transmit in a time sharing mode over a radio channel to a central unit. The information transmitted is identity, channel monitoring, status, alarm. The central processes the information and retransmits it over a different radio channel to a remote control unit where it is displayed and whence the alarm is given, e.g. siren etc. Individual alarm units can be designated as 'active' or 'off' by the central unit so that part of the establishment can be monitored while the remainder is occupied. Alarms can be set by patrols using radios on the alarm channel. The central sends an acknowledgement which is displayed visually to the patrol. A 'panic' button on the patrol radio sounds the alarm and gives an emergency display at the control.

Title: Flowmeter using ultrasonic pulses travelling in opposite directions - excludes instances when pulses coincide and measures frequency difference to determine flow speed and throughout
Inventor: ZALESSKIJ EDUARD ALEKSANDROVIC
IPC: G01P5/24
Filed: 1979-08-22
Abstract: The flow volume measuring circuit uses ultrasonics to determine both the flow speed and the throughput. It conveys two automatically circulating pulse sequences in opposite directions in an acoustic channel along the flow to be monitored. The throughput is measured on the basis of a frequency difference. The instances of pulse coincidence are excluded. The pulses of one sequence are derived from a self-excited generator whose frequency is a whole number multiple of the sequence. The coincidence instant is excluded by interrupting the sequence before it occurs and restarting an instant later. The frequency difference of the two sequences are obtained by comparing the two pulse frequencies.

Title: Ultrasonic scanner with image analog processor - uses two memories for signals from three successively scanned lines, also processed by two comparators
Inventor: GEBHARDT WOLFGANG DR
IPC: G01S7/52
Filed: 1980-10-08
Abstract: The circuit is for an electronic sector scanning appts. for ultrasonic medical diagnosis, e.g. for real time, two-dimensional echo-cardiography. In addition tothe field of medical diagnostics the circuit can be also applied to material testing. The ultrasonic signals, cycled by a burst generator, are emitted via a sector scanner into the tested material, and the stray signals are received and recorded on an image screen. The received signals from three sequential scanning lines are written into two memories in such manner that they are processed simultaneously by two comparators. Two comparators form a specified scan line difference with a plus value, while the other two comparators form such a difference with a minus value. An analog switch, such as an AND-gate, makes a switch when both differences are of positive value.
