Patent DE-1919175-B2 (DE)
Title: Oil sealing ring for trochoidal rotary piston engines - has ring gap and elastically resists centrifugal force
IPC: F16J9/00
Filed: 1969-04-16
Abstract: The oil gasket ring (21) is manufactured, by conventional means, with an unrestrained shape such that when it is clamped (22) for a standard test, a radial force Pp has to be applied to the gap (23) to reduce the ring diameter (D) to the figure for the rotor groove diameter, where Pp>=Pt, the standard test tangential force figure. This criterion replaces the standard test ovality criterion, in recognition of the fact that these rings are subject to high centrifugal forces opposing the inbuilt sealing force, particularly when the instantaneous centre of rotation is outside the ring, nearest the gap.

Title: Stencilling device for lettering - has grooves and twin form master stencil for easy change from upper to lower case letters
IPC: B43L13/20
Filed: 1970-04-27
Abstract: A stencil holding device has a pair of grooves cut in its edge section. The separation of these grooves corresponds to the separation of a series of upper and lower case letter stencils in a master stencil. In this way by moving the ridged sections of the master stencil from one groove to another an easy change from upper to lower case lettering, not necessitating separate stencils, is achieved. The holding device has non-slip inserts and by increasing the number of grooves a much enlarged master stencil may be accommodated.

Title: Voltage dependent switching relay - has parallel-connected variable resistors in series with relay coil
IPC: H01H47/10
Filed: 1970-11-20
Abstract: The voltage dependent switching relay is intended for making latch of a high-voltage power circuit breaker, and has an adjustment capability for correction of its response value. A parallel arrangement of two variable resistors with independent adjustment is connected in series with the relay coil. A parallel connection of a capacitor with a summation current contact for opening of the relay contact set is connected in series with one of the resistors. This arrangement makes the adjustment for correction of the response value unnecessary when the relay monitors the control voltage of the circuit breaker used e.g. in a motor drive.

Abstract: A packet data transmission system is used to link a number of remote hand-held data-gathering units such as bar code readers to a central computer which maintains a database management system. Data packets are sent from the remote units by an RF link to intermediate base stations, then sent by the base stations to the central computer by a serial link. A frequency-hopping transmission method is used for the RF link. The remote units and base stations are all synchronized to a repeating pseudo-random sequence of frequencies in a band (902-928 MHz) which allows this type of transmission. The remote hand-held units initiate an exchange using RF transmission to and from the base stations, receiving only during a rigid time window following a transmission from the remote unit. The base stations cannot initiate communication to the remote units, but instead send data to the remote units only as part of the exchange. The reply messages from the base stations to the remotes contain synchronizing information to maintain coherence with the pseudo-random sequence.
