Patent NL-7908945-A (NL)
IPC: C07C11/08
Filed: 1979-12-12
Abstract: A process for the simultaneous manufacture of pure methyl tertiary butyl ether (MTBE) and a substantially isotubene-free mixture of C4-hydrocarbons, by reacting the isobutene contained in the mixture of C4-hydrocarbons with excess methanol in the liquid phase at elevated temperatures on strongly acid, macroporous, organic ion exchange resins. The process has the following steps: (a) methanol and isobutene are reacted in a molar ratio of 2:1 to 5:1 at temperatures between 30 DEG  and 100 DEG  C.; (b) the unconverted hydrocarbons are then removed as the top product under a pressure of 2 to 10 bars from a first rectification column; (c) the bottom product from this first column is rectified in a second column under normal pressure or under a slight excess pressure of up to 2 bars at the top of the column, the bottom product of this rectification is recycled to reaction zone (a), if necessary, after separating off a portion of the tertiary butanol formed and the C8-olefins; and (d) the distillate from this second column is rectified in a third rectification column under a pressure of 5 to 30 bars, the distillate thus obtained is recycled into the feed to the second column and pure methyl tertiary butyl ether is withdrawn from the bottom of the third column.

Title: Animal silage feeding equipment - comprises fence assembly with one section thrust towards block or fodder enclosed
IPC: A01K1/10
Filed: 1980-06-26
Abstract: The animal-feeding equipment is partic. for sheep, and comprises a fence assembly, one part of which, with bars (7), is movable towards a block of fodder, e.g. silage (3), behind it. This part of the fence has support feet (4) bearing against the fodder and holding it clear of the latter. Thus the animals can pass their heads between the bars in order to reach the fodder, and as they eat it away the pressure they exert moves the fence towards it. The assembly can enclose a rectangular space accommodating the block of fodder, having two opposite fixed sections and two others which can be moved inwards towards it.

Title: Viscous fluid adjustable torque transmission unit - has working face of rotor disc corrugated to form wedge sections
IPC: F16D35/00
Filed: 1982-05-12
Abstract: The adjustable torque-transmission unit uses a viscous fluid in a narrow gap between the faces of two relatively rotatable bodies e.g. a rotor disc and a housing. The disc is also enclosed by a wider non-working space. Its working face has apertures at intervals over its surface, the rotor being smooth. The flow resistance in the radial direction through the gap is several times that in the non-working space and through the apertures and is mainly laminar and tangential External controls regulate the torque transmitted by the amount of fluid with which the gap is filled. The working face of the disc (3) is corrugated w.r.t. the radial plane, to form three or more asymmetrical wedge-shaped sections in the gap (5) round the periphery, opposite a solid and smooth face on the housing (2). The corrugations are within the mean width of the gap. In each corrugation, the wedge-shaped portion of the working face (3b) is several times longer in the peripheral direction than the steeper (3c) and non-working portion of the face.

Title: Identification system for farm livestock e.g. pigs - uses subcutaneous electronic circuits to keep track of animals during breeding, rearing and transportation
IPC: A01K11/00
Filed: 1987-12-18
Abstract: The system consists of a central detecting and recording station and electronic capsules which are hypodermically injected into each animal. Each electronic capsule contains a passive responder chip. When the animal comes within range of the detector, the responder provides data about the animal including a unique identification number. When a number of animals is taken to market or to an abattoir in several vehicles, the system can be used to sort them into appropriate groups for further processing. The data may also be communicated to a home base via a telephone modem link. Alternative capsules may be used which contain active transmitters in place of the passive responders.
