Abstract: 1,074,539. Selective signalling. SAMSON APPARATEBAU A.G. Dec. 16, 1963 [Dec. 14, 1962], No. 49643/63. Heading G4H. [Also in Division G1] Vibrations in a member such as a cord 4 (Fig. 1) attached to a lever 3 are induced by an electromagnet 8 and detected by an inductive or capacitive transducer 6, both connected to an amplifier 7, at a frequency proportional to a force applied to the other end of the lever 3 in response to a variable quantity such as pressure, fluid flow, or temperature. The frequency of pulses supplied to the electromagnet 8 is measured to give rate of flow, or integrated at 9 to give an indication of total flow in response to the differential pressures from a Venturi, 1. Refinements include a weight (10, Fig. 2, not shown) mounted on the cord to reduce the frequency of vibration, or else on oscillatory mass 12 (Fig. 3, not shown) attached by a rigid arm 13 to the cord. Zero errors due to slackness of the cord at low tensions are removed by reinforcing parts of the cord (15a, Fig. 4, not shown) or by attaching a bias spring 15 to the oscillatory mass (Fig. 3, not shown). In a further flow measuring arrangement (Figs. 6, 7, not shown) compensation for variations in pressure or density is effected by means of a further pressure sensitive bellows (28), which varies either the position of the pivot (24) between the arm (27) and the oscillatory mass (26), or the separation of two portions (29, 30) of the oscillatory mass. The vibrating member consists of rigid portions linked to each other, to the lever (3), and to the arm (27), by strip springs (20, 21, 22). In a temperature measuring embodiment (Fig. 5, not shown) the vibrating member consists of two rigid parts (16, 17) pivoted together and to the arm (13), the lever (3) being subjected to a force from an expansion thermometer (19).

Filed: 1977-12-02
Abstract: Novel 5-(subst. phenyl)-oxazolidinones and their sulphur analogs of the general formula I <IMAGE> in which the substituents are defined in Claim 1, are obtained by reacting 2-amino-1(3,4-disubst. phenyl)-ethanols with a carbonic acid derivative or a thiocarbonic acid derivative in an inert solvent while heating in the presence of a basic catalyst. The novel compounds of the general formula I possess valuable pharmacological properties. They exhibit antidopaminergic, antinociceptive and anticonvulsive effects and have a depressant action on the central nervous system and thus have a certain similarity to neuroleptic agents such as chlorpromazine or haloperidol. In addition, the novel compounds possess strong phosphodiesterase-inhibiting properties and thus affect the metabolism of cyclic nucleotides. The compounds are also suitable for treating hyperproliferative diseases and diseases associated with uncontrolled cell growth.
