Title: Pneumatic transport system for flour - has fan operating at constant pressure differential for maximum efficiency
Inventor: OETIKER HANS
IPC: B65G53/66
Filed: 1980-06-30
Abstract: The pneumatic transport system for flour is fitted with a centrifugal separator (2). The mixture of flour and air arrives by the pipe (7) which runs tangentially into the conical chamber (4) at the inlet (8). The flour falls downwards whilst the air is drawn upwards through the central pipe (11) and flows through the throttle valve (13) to the outlet duct (15). A fan in the outlet duct maintains the circulation of air through the system. This fan operates most efficiently at a constant pressure difference. This constant pressure difference is maintained by a flexible diaphragm (34) with one side exposed to the outlet pressure (21) of the centrifugal separator and the other side to the inlet pressure. Any change in this pressure difference acts on the diaphragm which actuates the throttle valve (13) to maintain a constant pressure differential.

Title: Method for determining the failure characteristic of a lamp circuit, and a circuit arrangement for carrying out the method
Inventor: HELFENRATH KLAUS DIPL ING
IPC: H05B37/03
Filed: 1981-05-29
Abstract: A method for determining the failure characteristic of a lamp circuit, especially of a lamp circuit of an airport illumination system whose lamps are connected in the secondary circuit of a current transformer. An element through which current flows and whose electrical parameters correspond to the electrical parameters of a lamp is inserted into the lamp circuit. The failure of a lamp is simulated by switching off the element through which current flows, the first characteristic value is determined using metrology techniques and is stored in a computer system as a simulated characteristic value. When a lamp actually fails, a further lamp failure is simulated by switching off the element through which current flows, and the second characteristic value is determined using metrology techniques and is stored in the computer system as the simulated characteristic value for two lamps having failed. All further characteristic values are determined using the same principle. <IMAGE>

Title: Method and circuit arrangement for electrically setting the height of the head wheel of video recording and replay devices
Inventor: SCHUELEIN REINHARD DIPL ING
IPC: G11B5/53
Filed: 1981-08-04
Abstract: This method and circuit arrangement reduces the work required for setting the height of the head wheel, that is to say avoids time-intensive mechanical setting processes. According to Figure 1, this is achieved by the fact that the remaining mechanical wrap of the magnetic tape (2) around the head wheel (1) is increased, the mechanical wrap is selected to be greater than the electrical wrap (video heads switched on) for reliable tape/head contact. The video heads for recording and replaying are appropriately switched and the phase difference between the frame pulse during recording and the crystal reference during replaying (reference value) and head wheel tachogenerator pulses (controlled variable) is set for adjusting the centre of the recording height (5) of the video tracks. Due to the fact that there is no mechanical adjustment of the head wheel height, the invention results in an increase of operational reliability of the video recorder and a reduction in manufacturing costs, the appropriate video standard being accurately maintained. The measuring and adjusting process can be automated, in particular, by using a microcomputer. <IMAGE>

Title: Box and device for its machine production
Inventor: LEONHARDT SIEGFRIED DIPL KFM
IPC: B31B105/00
Filed: 1981-09-02
Abstract: The invention relates to a box which is joined together from a casing blank (3), forming at least the bottom and two longitudinal sides, and two side blanks forming the end sides. The side blanks (2) have side flaps (9) which can be bent at the edges adjacent to the longitudinal sides (4, 5) and are attached on the inside of the casing blank (3). In the prior art, the side blanks are surrounded by bendable flaps of the casing blank. Due to the known shape of the casing blank, there is considerable punching waste during the production of a box, in particular the flaps stuck onto the outside of the blanks cause considerable loss of space when the boxes are stacked side by side. According to the invention, it is proposed to form the dimensions of the casing blank (3) to correspond to the dimensions of the bottom (6) and the longitudinal sides (4, 5) and to assign a bendable bottom flap (10) to the side blanks (2) on the edge adjacent to the bottom (6), the bottom flaps (10) and the side flaps (9) being fixed on the inside of the box (1). By means of the design of the casing blank (3) and of the bonding of the flaps solely on the inside of the box (1, Figure 1), a box is provided which can be stacked in a space-saving manner and in whose manufacture a minimum punching waste occurs. Furthermore, the invention relates to a device for folding the box (1) according to the invention, a ram (12) connecting the side blanks to the casing blank (3) in a positive-locking manner prior to folding. <IMAGE>
