The appts. has a housing (12). The side nearest the patient (5) has an acute angle (alpha) in which a light screen (3) is arranged behind a breast locating surface (6). The light beam is deflected by about 90 degrees and, with the aid of a lens, (8) an image of the breast is formed on a solid state detector (4). The latter is arranged on the side of the housing (12) furthest from the patient. To d...

The motor vehicle automatic gearbox is brought to an optimum gear setting, if the gear changing manipulation unit is brought in the automatic setting. Also the gearbox in a desired gear position, according to a gear changing command operation by a driver, if the manipulation unit is moved in to the manual setting. The cruise control system has a desired speed adjusting unit which sets the desired...

An exercise machine includes a base having a seat fixed thereto and a backrest pivotal to a number of positions. A chest developing unit pivots with the lower portion of the backrest. The chest developing unit includes bilateral handles which are linked by a rack and pinion mechanism and resisted by an elastic band. A top exercise unit is mounted between horizontal supports extending from the top ...

The system aligns stacks or their supports at the inlet and outlet of a press, having a transport mechanism working at right-angles to the travel direction of the printed sheets. This is inserted in the inlet and outlet and aligned with the machine centre. Sensors (S1,S2) are situated on the spin path travelled by the transport mechanism (T), while the drive (M) for the latter has a signal-emitter...

For the separation of solids from a suspension, by flotation, the suspension is eddied in the clarifying zone (1) into a rotating and swirling movement (2). In the axial direction (4) of movement, the max. dia. (D1) of the swirling suspension at the inlet (13) is larger than the min. dia. (D2) at the outlet (14) and the transit between the dias. (D1,D2) has a contour (6) which is curved inwards. T...

A cone crusher with wear indicator. The cone crusher comprises a frame, a head rotatably supported on the frame, a bowl supported on the frame in spaced relation to the head, a liner mounted on one of the head and the bowl, and an indicator for indicating wear of the liner. Preferably, the indicator includes a recess defined by the liner, and the recess is revealed upon erosion of the wearing surf...

The invention relates to a system for simultaneously navigating two or more vehicles over a surface of relatively limited dimensions at relatively high speed and/or density of these vehicles, comprising: a central control unit (30) at least provided with a computer with memory and a transmitter/receiver (31) for communication with each of the vehicles; marker elements which are arranged on or abov...

Obtaining aqueous solutions of homo- and/or copolymers of ethylenically unsaturated monomers comprises using compounds containing a phosphorus atom with a degree of oxidation 5, in quantity of 0.005-0.49 mol. per mol. unsaturation, for polymerisation in presence of hydrogen peroxide and absence of all free radical decomposition agents and free radical generators.
