Title: Transporter carrying vehicles vertically - vehicles are loaded on horiz. platforms tipped to vert. positions
IPC: B60P3/07
Filed: 1973-04-17
Abstract: Most transporters have two floors on which vehicles are loaded horizontally, or nearly so. The maximum number carried is determined by transporter's permitted dimensions. The patent covers a series of platforms (one per vehicle carried). The wheels run into special housings and are secured by a screw device. The platform pivots 90 deg. and thus tips the vehicle to a near vertical position. The process is repeated and can be applied to road or rail transporters. Vehicles can be loaded initially longitudinally or laterally (with regard to the transporter vehicle). The tipping of the vehicle can be done either mechanically or electrically.

Title: Multiple access data transmission system - compares levels on a single channel to control access
IPC: G06F13/368
Filed: 1975-02-21
Abstract: This data transmission system permits the use by several transmission terminals of a single communication channel by the means of determining and restricting the access into that channel to active transmissions. A level is established on the single channel that permits the acceptance of a transmission. At each channel the level that a terminal tens to impose on the channel is compated with the actual level appearing on the channel. Terminal transmission is stopped if a level is detected that is not compatable to the single channel. The comparison level of the main channel is Ov and is independent of levels that other channels may attempt to superimpose upon it.

Title: Detection of liq. zone in continuous casting - by creating magnetic field and comparing with reference value
Inventor: RUER JACQUES
IPC: B22D11/20
Filed: 1976-05-28
Abstract: A process and device for detecting and measuring liq. metal cores in slabs of large cross-sectional area during solidification in continuous casting are described. The prod. is subjected to an alternating magnetic field in the thickness direction, perpendicular to the direction of extraction at a point between two successive rollers. The magnetic field is then compared with a reference value representing the magnetic field obtd. from prods. in a state where they have a thickness relatively equal to the distance between a pair of rollers. A deviation signal is worked out; the signal representing the thickness variation of the prods. during their passage through the space between successive rollers. The signal is then visualised or used in the automatic control of the casting operation. Rapid detection and measurement of the liq.-zone thickness in the centre of the casting is possible without any risk to safety. Control of the continuous casting machine is possible.
