Abstract: An endless spring is an elastic body such as an oval or elongated or circular ring body for the transmission of loads in a main plane substantially centrally through the endless or ring body. Such a main plane extends in the plane of the drawing. The ring body is made up of a plurality of winding layers of fiber reinforced synthetic material. The windings in certain central body layers (2) preferably extend unidirectionally and the fibers in intermediate layers (3) and in outer layers extend at an angle relative to a main load application direction. The whole spring body includes a plurality of intermediate layers (3) and a plurality of outer layers (4) of synthetic resin impregnated fabric plies. The central body layers (2) form a winding body.

Abstract: A method for D.C. braking a three-phase asynchronous machine and a circuit arrangement useful in implementing the method. For braking, the first and third stator windings are separated from their phases and a pulsating direct current is caused to flow from the second phase to the first phase via a closed second switch and a diode. The third winding is short-circuited by a third switch which is connected in a loop with a current transformer; the loop carries a current induced by the turning rotor. A signal from the current transformer flows, via a limit indicator, to a digital logic member (OR). When the motor stops, short-circuit current flow is no longer detected, the second switch is opened and the circuit for producing direct current is automatically disconnected.

Abstract: A process for the production of silicic acid heteropolycondensates, wherein at least one hydrolysable silicic acid derivative; at least one substituted silane; optionally at least one functional silane and/or optionally at least one substantially involatile oxide soluble in the reaction medium or at least one compound forming a substantially involatile oxide are condensed in the presence of at least the quantity of water stoichiometrically required for hydrolysis and optionally in the presence of a condensation catalyst and/or a solvent. The polycondensates are useful in the production of membranes and adsorbents.

Abstract: A tire valve cap with a built-in pressure indicator consisting of a housing structure with a spring-loaded diaphragm piston exposed to the tire pressure, the axial movements of the hub of the diaphragm piston being converted into angular movements of a pointer shaft and pointer member through a helical cam connection. The position of the fixed pointer is adjustable, and the pointers are radial protrusions whose position can be ascertained visually or by finger touch.
