Title: Compression-stress generation system in rail foot - upsets rail head during cold-rolling when straightening
IPC: C21D1/00
Filed: 1990-02-27
Abstract: Compression stresses are generated in rail feet by cold-rolling when straightening. This upsets the rail head and stretches the foot, without affecting straightness of the rail. During heat-treatment, the rail head can be heated to over 600 deg.C. for subsequent bending. The consequent reduced resistance of the rail to shaping results in very small residual tension stresses in the foot.

Title: Device for automatic unstrapping of safety belt
Inventor: JERAS PAVEL
IPC: B60R22/32
Filed: 1999-11-19
Abstract: The subject of invention is a device for the automatic unstrapping or release of a safety belt which enables the automatic disconnection of the safety belt after its sudden and impulsive loading caused for example by a crash or overturn of a motor vehicle, in case the vehicle has stood still for a certain time after the event in which the loading of the belt had occurred. The solution is given by the submitted structure of the device for the automatic unstrapping of the safety belt. It consists of a chamber, (1) fixed at one point of the three-point safety belt (e.g. at the fixing point on the floor), in which a piston (2) and a pendulum (14) with a lever (15) are moving. The piston (2) contains a capsule (13) filled with gas which expands according to the movement of the piston (2). The movement depends on the openness or closeness of a gas flow hole (11) within the piston (2), which in turn depends on the vibration or movement of the whole device.

Title: Propeller mechanism
Inventor: ALEKSANDROV DOBROMIR KH
IPC: B63H1/14
Filed: 1995-10-20
Abstract: The propeller mechanism is designed for traction devices operating in fluid medium. It has reduced shading of the propeller blades and the hydraulic resistance. It consists of two adjacent propellers (1 & 2) having concentrical axes (3 & 4) interconnected by gears (7). At least one row of holes (8 & 9) having arc-like shape and interconcentrical positioning are machined in blades (5 & 6) of propeller (1 & 2). Holes (8 & 9) are dephased diagonally where holes (8) of one of the blades (5) are axially projecting between the holes (9) of the other blade (6). Holes (8 & 9) increase their longitudinal size in the direction of the outgoing part of the blades. The gear ensures opposite revolving of propellers (1 & 2) having the same r.p.m. at different directions of the angle of inclination of blades (5 & 6). In another exemplary implementation gear (7) ensures unidirectional revolutions of both the propellers having different speeds and unilaterally established angles of the blades in ratio between their effective surfaces determining the same discharge of the propellers (1 & 2).
