Title: Enclosed loading rotor for operation under different pressure - has pressure compensation between empty and full chambers
Inventor: TOTH SANDOR
IPC: B65G53/46
Filed: 1976-02-18
Abstract: A horizontal loading rotor moves granulated bulk between inlet (25) and outlet (29) which are of different pressure. The rotor has a number of radial chambers (2) which are enclosed by two parallel end plates. One end plate has two pairs of communicating airlines (31, 32) which allow a pressure balance between the rotor chambers. As a full chamber moves away from the loading station, it reaches the first of the balancing air lines where its internal pressure is increased. As it passes the second airline the pressure is further increased to that of the unloading station (29). In the empty chambers the pressure is reduced to that of the loading station.

Title: Video frequency colour bar signals generation - uses addresses applied to stores to determine colour bars in pattern and further addresses to determine sequence
Inventor: ILLETSCHKO GERHARD
IPC: H04N17/04
Filed: 1976-06-16
Abstract: Binary vlaues derived by frequency division of a signal coupled with horizontal and/or vertical frequency serve as addresses for a store. Depending on this address binary values representing a certain colour are read out from the stores, and digital values are converted by D/A conversion into vide frequency colour bar signals, as in DT2615783. Addresses obtained by frequency division determined the position of a colour bar pattern generated by the colour bar signals. A sequence of colours is determined by further addresses applied to the store.

Title: Electric control of physical variables - uses signal corresponding to variable which is converted into two-step signal and applied to control element
Inventor: JUCHHEIM PETER
IPC: G05B11/10
Filed: 1976-06-18
Abstract: The variables can be pressure, speed, rate of flow, humidity, power, temp. etc. They are controlled in a control system by control elements with proportional action. At first a signal corresponding to the variable is converted in a two-step controller (10) with a feed-back into a two-step signal which is then applied to an electric store independent from the behaviour of the control system or of control elements. Store time constant is many times greater than the two-step controller cycle, and the store output signal is applied to the control element.

Title: Cement clinker mfd. from low grade materials - with mechanical grinding and homogenisation
Inventor: NIEMEYER ERNST AUGUST DIPL ING
IPC: C04B7/38
Filed: 1976-12-20
Abstract: Cement clinker may be prepd. from as-mined materials, which because of their high water content and other physical properties are unsuitable for dry processing, and for which filtration after wet processing is also unsuitable. The raw materials are not dressed to raw powder, sludge or filter cake before burning, but are mechanically reduced and homogenised from the as-received condition and then fired with the original moisture content or after pre-drying. Lower grade raw materials may be used. Less energy is required for firing than with wet processing.

Title: Disposable foil grill tray for clean cooking - has punched out holes allowing quicker cooking and browning than normal foil
Inventor: VOEGLER PETER EBERHARD
IPC: A47J37/06
Filed: 1977-03-30
Abstract: The disposable foil grill tray is preferably made of aluminium foil and has punched-out holes so that it is used once only in place of the grid or as a cooking tray on the grid or as a cooking tray on the grid. The shape and size of the foil can be matched to the grill cooker which is to be used. Depending upon the thickness of the foil the holes should take up between 60 and 70% of the overall surface with the shape of the holes being irrelevant. The size of the holes depends on the food to be cooked and should preferably be in the range from 5 to 30 mm. The stability of the foil can be increased by a firm peripheral strip 10 to 20 mm wide. This grill tray provides a more effective contact between the heat of the fuel source and the food to be cooked whilst still allowing the food to be cooked without soiling the grill.

Title: Laboratory safety gas bubbles counter - has double sleeve with inner funnel shaped insert sepg. inner space from sealing liq. space and gas exit
Inventor: PAULY KARL-HEINZ
IPC: G01F1/704
Filed: 1977-05-13
Abstract: Safety gas bubble counter for laboratory use in analytical or preparative applications has a gas inlet at the bottom, a pressure equaliser at the top and a gas exit at the midpoint of a double sleeve construction. Gas passes up an annular space between an inner container for sealing liquid and the outer wall of the assembly. The annular space is sealed off at the top and the gas passes, via orifices in the upper wall of the sealing liquid container, into an inner funnel shaped insert sepg. the inner space from the sealing liquid space and the gas exit. The gas displaces liq. in the funnel shaped insert and bubbles up via an opening in the bottom of the insert to the exit tube. Under conditions in which the pressure in the system is below atmospheric pressure the pressure of the atmosphere via the equaliser pushes liquid upwards without it entering the gas exit.
