Title: Control circuit for dual slide projector - has interlocked drives with holding controls for synchronising actions
Inventor: WALTER ANNEMARIE
IPC: G03B23/00
Filed: 1979-03-03
Abstract: The slide changer control for a projector has a first control impulse to index the magazine and to stop the slide changer mechanism at a set point, ready for sliding into the projection position. The magazine indexing and the slide changer action are operated by a cam driven by a servo motor. The control is extended for dual projectors in which the slide mechanisms are alternately stopped in the ready positions, from which the slides are rapidly moved into the projection position. The system ensures that the dark time of the shutter is kept to a minimum for a more comfortable projection. The control is also used to fade successive scenes into each using the dual projector. The time duration from the projection change to the shutter movement, at each end of the time scale, is from 1/5 to 1/4 of the total time.

Patent DE-2936188-A1 (DE)
Inventor: HOETGER KARL
IPC: B65B19/34
Filed: 1979-09-07
Abstract: Arranged in front of the ends (39) of the bar-shaped parts (38) held in a container (40) is a filling funnel (20) having an axis parallel to the axial direction of the parts (38). The box (6) is aligned coaxially with the filling funnel (20). A pressure cylinder (4) then, via a crosshead (7) and a crosshead stop (12), pushes the box (6) with its open end face onto the narrowed end of the filling funnel (20) and thereafter, via a further crosshead stop (11) and a filling-funnel crosshead (8), pushes the filling funnel (20) together with the box (6) further towards the bar-shaped parts (38), until their ends (39) have entered the filling funnel (20) and are flush with the outlet end of the latter. Another pressure cylinder (3) then pushes the filling funnel (20) alone further and out of the box (6). The filling funnel (20) is thereafter divided longitudinally and the halves (21, 25) are retracted transversely to the axial direction of the bar-shaped parts (38), whereupon, finally, the box (6) is pushed by a pressure cylinder (13) further onto the bar-shaped parts (38) as far as the container (40). This avoids the hitherto customary manual slipping-on of the boxes. <IMAGE>

Title: Multi-colour LED display for seven segment figures - is used in calculators or measuring instruments and employs transistor or direct switching without supply voltage polarity change
Inventor: GILLESSEN KLAUS DIPL PHYS DR
IPC: H01L33/48
Filed: 1980-03-12
Abstract: The L.E. circuit consists of seven groups of diodes (a-g), each group made up of two diodes (1,2), one red and one green. The cathodes of all the red diodes are terminated in a common connection (K1), and the green ones likewise (K2), the anodes of each pair of diodes being common for that pair (a-g). Each set of cathodes is connected to a supply voltage source via a resistor (R,R2) and transistor collector (T1,T2), the emitters of both the latter connected to ground. When a low level signal is applied to the base of the first transistor (T1), current flows via the second transistor (T2) and common cathode connection of one set of diodes when a high level signal is applied, the second transistor (T2) is blocked, and current only flows via the first transistor (T1), and common cathode connection of the other set of diodes. The circuit is used as a seven segment indicator for calculators or watches.
Patent DE-3009926-A1 (DE)
Inventor: WUETHRICH HANS-RUDOLF DIPL ING
IPC: H01H33/56
Filed: 1980-03-14
Abstract: A shaft (5) which can pivot in a limited manner about its longitudinal axis is inserted into the switch housing, which is sealed in a gas-tight manner. One end of a rubber hose (8), which is coaxial to the shaft (5, 6), is connected to the shaft (5, 6), and its other end is connected to the switch housing part (1'), in a gas-tight manner, as the gas seal. Loose supporting rings (10), which are guided coaxially with respect to the shaft (5, 6) and, lying one on top of the other, form a stack, are placed on that side of the rubber hose (8) which faces away from the increased pressure. These supporting rings (10) advantageously have self-lubricating properties, so that a large portion of the friction takes place between these supporting rings (10) and their guide (1), since the rubber hose (8) cannot be deformed in an undesirable manner by the increased pressure which acts through the annular gap (9) on the inner surface of said rubber hose (8), which also considerably increases its bursting strength. A sleeve (1) or even the shaft (105) can be used to guide the supporting rings (10 or 110). The shaft (105) is used when the increased pressure acts on the outer surface of the rubber hose (108). <IMAGE>
