A 6-O-methylerythromycin A derivative represented by the formula and the salts thereof are useful as intermediates for the preparation of 6-O-methylerythromicyn A and are themselves useful as antibiotics.

13-Hydroxy-5-ketomilbemycin derivatives are prepared by oxidizing a 5-ketomilbemycin with selenium dioxide in the presence of a lower aliphatic carboxylic acic. A range of new 13-acyloxy-5-ketomilbemycins and a method or preparing them are also disclosed.

1. Apparatus for an automobile, consisting of a) a central electrical unit (1) for the central connection of electrical components, such as cable harnesses, plug connectors, fuses (17) and switching devices (18), electronic controls for electrical consumer units, such as lamps, windscreen wipers, indicator lights, heaters, solenoid valves, b) the central electrical unit (1) possesses conductor pat...

A balloon catheter having an expandable and collapsible elastic balloon is shown, wherein the balloon is reinforced by knitted fabric such that the balloon can not expand beyond a predetermined diameter regardless of the internal pressure applied to the balloon. The knitted construction permits the balloon to expand in diameter without shortening in length, and permits the balloon to collapse smoo...

The mounted transmitter includes a resonant horn which is integral with one surface of the wall. Specifically the box contains a resonant forn connected to a e.g. pneumatic drive via a tubular piece which passes through the wall.

There are pref. two data support surfaces which are positioned at an angle to each other so that they cannot be seem simultaneously from a position in front of them. On the surfaces or on a separate data carrier, pref. a oldable sheet of cardboard, are arranged centered columns (7,71,72.....) bearing on the one side (8) questions and on the other (9) answers. For the two data support surfaces, the...

An elastic heat tube which comprises an inner soft annealed copper tube, with a plastic film sleeve. This is surrounded by an insulation layer e.g. asphalt and a polyurethane foam layer. This has a density of 90 kg/m3. There is a flexible plastic protective tubular covering e.g. PEH GM 5010.

The machine has a tool (21) which produces a flat, unworked seed bed, and a spreader (40) which distributes seed onto the prepared bed. It also has a conveyor belt (23) which moves at least part of the earth taken up by the tool to a point to the rear of the seed spreader where it is deposited over the sown seed. - The tool extends across the forward movement direction of the machine. The tool has...

The invention is a seeder comprised in part of a plowshare (21) that takes up earth in order to generate a flat, unprocessed seedbed and in part by a spreader (40) designed to spread the seed on the seedbed. The machine also comprises a means (23) of transporting at least part of the earth that has been taken up from the plowshare to a point behind the spreader, where earth is spread over the seed...

The machine has a forwardly facing tool which enters the surface layer of the soil, some of which it picks up. The tool cooperates with a four-armed breaker which rotates and breaks up the collected earth, causing it to be deposited on to an endless conveyor belt. - The belt distributes the soil at the rear of the machine over sown seed.

The machine incorporates an endless conveyor belt which moves at least part of the soil removed by the prepn. tool to a point to the rear of the seed spreader. Here it is deposited over the sown seed. - The soil prepn. tool extends along the complete, working width of the machine, and is divided into a number of sections. Each section is movably suspended, so that when an obstacle in or on the gro...

The machine has an endless conveyor which moves at least a part of the soil removed by a flattening tool to a point at the rear of a seed spreader. Here it is deposited on top of the sown seed. - Both the seed spreader and a mechanism for crumbling and depositing fertiliser are provided between the flattening tool and the point where the removed earth is distributed. The latter is behind the forme...

In the machine, the action of earth removing tools forms strip-shaped seed beds separated by higher levels of soil. The earth is sieved into a fine and a rough structure. - The seed is laid on the beds which are covered with earth from the finer structure. The rougher soil is pushed down on to the unworked ground surface.
