Patent DE-1800931-A1 (DE)
Title: Chemical embossing thermoplastic sheet material
Inventor: HENRY WITMAN JACK
IPC: D06N7/00
Filed: 1968-10-03
Abstract: Imparting an embossed appearance to a thermoplastic vinyl sheet e.g. for floor coverings, is effected by blending a vinyl resin, pref. polyvinyl chloride, and plasticiser and forming the blend into a sheet. To the sheet there is applied in a predetermined pattern a liquid composition which is able to penetrate into the sheet and comprises a blowing agent which decomposes when heated to a temp. in the range of from the glass transition temp. of the plasticised vinyl resin to the decomposition temp. of the resin, pref. a liquid azoester e.g. diethyl azodicarboxylate. The printed sheet is then heated from 300 degrees F to 450 degrees F to fuse the plasticised resin and decompose the blowing agent. The resin may be blended with 20-130 parts of plasticiser per 100 parts of resin conveniently in the form of a plastisol. Suitable plasticisers include dioctyl phthalate, dioctyl sebacate and dioctyl azelate.

Title: Time limit warning system for public speaking - uses timing circuitry and logic to drive lights of increasing brightness and eventually a flashing light
Inventor: SCHILLING ERIK VON DIPL ING
IPC: G08B5/36
Filed: 1973-09-10
Abstract: The system alerts a public speaker to the face that his allotted time is running out, or, eventually has run out. The system consists of an accurately timed multivibrator with a period of 30 seconds, which feeds a series of flip flops through a Schmitt trigger and amplifier, so that time intervals up to 8 minutes can be decoded. This is done in a suitable logic decoder, which in turn drives lamps of increasing intensity at 4 and 6 minute intervals. After 8 minutes a flashing lamp driving circuit is activated and further counting is inhibited. Various other signals of increasing urgency are possible, all of which are visible to the speaker, but not to his audience.

Title: Shaft position encoder code and decoder - has properties which allow error checking by a simple logic network
Inventor: TAEUBER REINHARDT
IPC: H03M1/00
Filed: 1973-09-24
Abstract: The number of codes suitable for use in digital shaft encoders and their associated decoding logic are presented together with the logic networks required for their operation. Each code has the property that only one bit changes between segments of the shaft encoder disc, so that signal ambiguity is avoided and in addition has certain error checking properties. The first code dealt with is the Libaw-Craig code, using a binary coded decimal format. Each binary digit comprises five bits arranged in this code. The logic converts the code to give a ten's complement output, which is used together with the straightforward output to check whether bits are missing or not.

Title: Reactor insert for exhaust gas detoxification - with conically tapering inlet end
Inventor: WOESSNER GUENTER DIPL ING DR
IPC: F01N3/24
Filed: 1974-06-15
Abstract: In an exhaust gas reactor esp. for i.c. engines; having a tubular housing for the reception of at least one pref. monolithic reactor insert through which the gases flow longitudinally and having a connecting pipe leading to the smaller cross section exhaust gas feed pipe., the reactor insert is longer in the axial zone than at the edge zones, so that in the region of greater flow energy a greater flw resistance is attained as a result of the corresp. increase of the length of insert flow path in the centre of the flow, and therefore a more uniform flow over the whole cross section of the reactor is obtainable. The arrangement gives a more efficient and uniform detoxification of the exhaust gases as well as a longer life of the reactor insert, since the centre zone is not burnt out prematurely.

Title: Final forming of electrolytic wound capacitors - uses two parallel tensioned copper wires for spot welding capacitor lead wires
Inventor: HAIDINGER ERICH
IPC: H01G9/00

Title: Power assisted steering for tiltable cab vehicles - has steering wheel shaft with cross slot connection with worm drive
Inventor: WAGNER HEINRICH
IPC: B62D5/24
Filed: 1974-06-29
Abstract: An axial displacement occurs at the steering worm drive shaft (4) each time the steering nut (5) meets with a resistance. Should the resistance be greater than the pre-tensioned force of the limit spring (3) the steering worm shaft and with it the connected regulator piston moves axially. To compensate for this movement, the connection between the two shafts is formed by a cross slotted disc (9). The steering worm shaft and the steering shaft have axial projections at their neighbouring ends which mesh into corresp cross slits in the connecting disc, to form an extremely short connection between the two shafts. To avoid noise and friction, the projections and or the cross slits are coated with a plastic having a low friction value.
