Title: Weft less reinforcing layers particularly fire cords - with uniformly spaced threads
Inventor: HEINZ SKLORZ DIPL-ING
IPC: B29D30/38
Filed: 1969-03-28
Abstract: Threads are drawn separately from a creel, to form a sheet of threads which is wound onto a warp beam. Individual sheets are joined and embedded into unvulcanised rubber by means of a calender. Uniform distances between the individual threads in a sheet are maintained by means of a comb which is primarily inserted into the end of a beamed warp and locked. The beamed sheet of thread is thus supplied to the calender together with its respective guide comb. Immediately before feeding the starting end of the warp sheet to the nip of the calender, the comb is unlocked by a special device and put into working position. The comb is ejected after the sheet has completely passed the nip.

Title: Pulsed radar anticollision system - uses reflected pulse receiver with amplifier and amplitude threshold
Inventor: GOLOMBEK WERNER DIPL ING
IPC: G01S13/931
Filed: 1973-06-09
Abstract: The pulsed radar system is for the prevention of rear collisions of motor vehicles is able to distinguish trees or houses from motor vehicles and does not depend on the conscientiousness of the driver. The receiver for the reflected pulses is fitted with an amplifier and an amplitude threshold. Gain and/or threshold are variable as a function of time after every emitted pulse in accordance with the radar equation. This changes the sensitivity such that the echo pulse of a targe which corresponds to a certain radar cross-section has a constant height at the amplifier output from a min. to a max. distance. A signal derived from a pre-et min. distance and the relative velocity between two successive motor vehicles warns the driver of an impending collision.

Patent DE-2340726-A1 (DE)
Title: Combined mixing and milling of pastes - fine dispersions achieved in one machine by sequential action
Inventor: DUERR HERBERT DIPL-ING
IPC: B01F13/10
Filed: 1973-08-11
Abstract: Fine dispersion of solids in liquids or fusible material (e.g. pigment dispersions) is achieved by combining a mixing device nfor corse dispersion) with a liquid mill (to achieve fine dispersion). The mill consists of a vessel filled with coarse material, sand, beads etc. with agitation. The liquid and solid feeds enter the mixer directly and proceed without break straight into the milling section. The mixer is a crew type and is followed by the milling section with its filling of beads. The mill can be horizontal or vertical. The feeds are metered directly into the screw. The milling is by normal grinding between the filling caused by the agitation. The mixer can have >=1 mixing shafts. Feeds can be introduced at several intervals along the screw. The two sections can be driven by one shaft with a common axis. The mill has a separator to retain the milling particles, for given viscosity range. This is of use where fine dispersions of solids in liquids are required, e.g. pigment dispersions. Avoids the formation of coarse agglomerates when the powder is first introduced into the liquid which cause bad dispersions and can even jam the mixer.
