The entry slot of a granulator for comminuting material fed as sheets (especially cathode copper) is bounded on one side by a fixed bearing surface 5 aligned with the fixed blade 3 at which the initial cut will be made. On the other side it is bounded by a member 6 (or possibly more than one member) which is resiliently supported and biassed towards the bearing surface. This accommodates variation...

A welding sleeve for connecting pipes formed of thermoplastic material includes an electrical conductor in the form of an electrical resistance wire. The resistance wire extends around the sleeve and has a pair of opposite ends for conveying current through the wire. The opposite ends of the wires can be connected directly to a source of electrical current, for instance a 220 DEG V DIFFERENCE lin...

1. Process for the preparation of 3-(10,11-dihydro-5H-dibenzo [a,d]-cyclohepten-5-ylidene)- N,N-dimethyl-1-propanamine-N-oxide dihydrate and its acid addition salts which comprises reacting 3-(10,11-dihydro-5H-dibenzo [a,d]- cyclohepten-5-ylidene)-N,N-dimethyl-1-propanamine with 25 - 85% hydrogen peroxide solution at 30 - 95 degrees C for a period of 20 minutes to 4 hours, isolating the resulting ...

The invention relates to a fixture for counteracting skewness in side-mounted windows or doors resulting from settling or wear. The fixture which is intended to be arranged on the side facing the hinge consists of a link arm 1 which at one end is connected in an articulated manner to a pin 4 fixed in the edge of the window frame 5 or door, and which at its other end is slideably connected to the w...

Dihydropyridine derivs. of formula (I) are new. R1 = CH3, C2H5, 2-(methoxy or ethoxy) ethyl or (CH2CH2O)2CH3. R2 = C2H5, isopropyl, tert. butyl, 2-methylpropyl, 2-isopropoxyethyl, CH(CH3)CH2. OCH3, C(CH3)2CH2OCH3, propargyl or 2-methylallyl. R1 and R2 may not be the same. R3 = Cl or CH3O; and R4 = Cl, CH3 or CH3O. - (I) are antihypertensives. At low doses they selectively dilate peripheral rather ...

Information transfer system using a communication medium (1) and a number of information transmitting and/or receiving units, by which each unit connected to the communication medium (A) supplies or produces a reference frequency (2). The reference frequencies (2) for all of the units connected to the system are mutually so chosen, that these form synchronous frequencies in relation to each other....

The invention concerns a continuous casting mould with an electromagnetic agitator (1). The mould is characterised by having a number of, for example, four, continuous cast enclosing plates (5) of copper or copper alloy and an agitator, positioned outside the plates, whereby at least the one or all the plates facing the agitator are fitted with slots of a smaller width than the plates.

The structural support, e.g. for supporting a building panel, includes a surface in which is arranged a number of weakened portions (11,12) such as apertures or indentations. In use, the panel is fixed to the support by fasteners (such as nails or screws). The support is pref. made of sheet metal. The weakened portions are arranged close to each other, while the surface portions between these weak...

The device is for compartmentally collecting pieces of timber at a collector station. In the compartments, the timber can be held and subsequently sent further on their way via a conveyor system situated under the compartments. Each compartment is made up of flexible bands which form ever-increasing 'pouches' as more timber floats in. Their floors are made of parallel bars and are pivoted at one e...
