1,3-Diamino-2,2-dialkylpropanes whose alkyl substituents are each of 1 to 4 carbon atoms are prepared by reacting the corresponding 2,2-dialkylpropane-1,3-diols with ammonia in the presence of hydrogen under superatmospheric pressure by a process in which the reaction is carried out in solution and in the presence of a cobalt-containing catalyst.

An addition of 0.01 to 1 % by weight of complex hydrides, in particular sodium borohydride or potassium borohydride, prevents the discoloration of sodium alcoholates and potassium alcoholates in which the alcohol moiety is derived from aliphatic monohydric alcohols having 1 to 6 C atoms, as a solid or in a 1 to 30 % by weight solution in the corresponding alcohols, and of solutions of 1 to 30 % by...

A machine for slicing slabs of cheese, sausage or the like comprises a feeding mechanism which supports the slab, feeds it intermittently at an inclination to the horizontal and includes a slab-supporting conveyor belt and gripping claws for holding the back of the slab. The conveyor belt runs over freely rotatable direction-changing rollers and on both sides of the conveyor belt parallel to the u...

An activating magnet having two coaxial pole tube portions which are spaced from each other, have the same inner and outer diameters and are connected with each other by means of a connecting ring of solder. In order to create an activating magnet in which the pole tube portions need only be machined on the outside or inside diameter, a spacing ring of a non-magnetizable material is arranged betwe...

Living, fermentable yeast cells are prepared having an enzyme or mixture of enzymes coupled thereto. Enzyme coupling is carried out by contacting at least partially dehydrated living yeast cells with an aqueous enzyme solution to cause the yeast cells to rehydrate and a layer of enzyme to form on the surface of the yeast cells, and than contacting the rehydrated yeast cells with an enzyme-precipit...

An electronic monitoring device monitors the operation of a device which functions regularly at preset intervals, e.g. a cyclic polling operation as in the telephone exchange of our Application No. 82 28206 (G. A. Sarson et al 5-4-1). This device includes a first monostable (MS1) which is polled at a 100 ms rate, and if a poll is missed the monostable changes condition to give the processor a "sof...

The control system comprises an induction cable installed along a running course between a loading station and unloading station, a detecting coil mounted on a work vehicle for detecting current flowing through the induction cable, a steering control device responsive to the output of the detecting coil for steering the vehicle to run along the running course, a vehicle position detector for detec...

An improved annular shaped tire liner which is adapted to fit inside of, around and in contact with a casing of a pneumatic tire and in compression by the casing and a method for preparing the tire liner is described. The liner has a thickness which provides substantial protection against penetration of the tire to the inside of the casing. The tire liner is characterized by having a section which...

A method and apparatus for grooving a tire (14) tread in which a computerized numerical controller (64) regulates the positional relationships between the tire and a hot cutting knife (54). The controller (64) through a plurality of servo motors (38, 48, 58, etc) causes the tire (14) to rotate in a vertical plane while effecting lateral and rotational movement of the cutter knife (54) in each of t...

A sterile disposable bottle having concertina walls and closed with a break-off toggle closure. When this toggle closure has been broken off the concertina walls can be compressed and the bottle emptied. The connecting piece of the neck advantageously has fastening devices, such as a Luer cone and a screw thread for a correspondingly designed Luer connector.

A circuit arrangement for monitoring electronic computing chips in motor vehicles (watchdog circuit) is proposed, such a computing chip outputting periodic signals for controlling an output stage (11) in correct operation. A continuously varying memory content of a memory (14) is set to a fixed value in dependence on these signals, and a reset signal for the computing chip is generated when the me...

The bond strength of composite articles of rubber adhered to ferrous metal substrates through an adhesive is substantially improved at ambient and elevated temperatures by depositing a specified amount of a layer of copper on said ferrous metal substrate, applying an adhesive thereover comprising an interpolymer containing about 50 to about 99% by weight of a conjugated diene, about 1-45% by weigh...

A process for treating plastisol-type vinyl chloride resins having small particle size and relatively little capability for absorbing plasticizers such that the plastisol absorbing capabilities of the resins are improved.
