Abstract: The invention concerns a device for pressing a side wall (1) of an installation for continuous casting of metal strips between two cooling drums with horizontal axes against the planar surfaces of the cylinders, comprising three thrust member connected to a mounting frame (3) maintained in a fixed position, exerting their action on the rear face of a plate (2) on the front face whereof is fixed the side wall (1) or on the rear face of the side wall (1), said action being oriented along a substantially horizontal direction (Oy) parallel to the axes of the drums and being exerted via means connecting each of said thrust members on said plate. Said connection means of a first thrust member enable a relative displacement in translation of said thrust A-4 member and of the plate (2) or of the side wall (1) being along a horizontal direction (Ox) a=parallel to the plane of the planar surfaces of the drums and along a vertical direction (Oz) parallel to the plane of the planar surfaces of the drums. Said connection means of a second thrust member enable a relative displacement in translation of said thrust member and of the plate (2) or of the side wall (1) along-a horizontal direction (Ox) parallel to the plane of the planar surfaces of the drums. Said connection means of a third thrust member do not enable any relative displacement in translation of said thrust member and the plate (2) or of the side wall (1).

Granted: 1998-02-06
Abstract: The invention relates to the field of ultra-light aviation for sport and recreation. This aircraft raises itself vertically from very small surfaces or pools of water and also flies horizontally, acquiring lift. It supports itself in the air at a fixed point. It also flies at very slow speed, moving among obstacles without a risk of falling as a result of striking them. It is provided with a ballistic parachute which supports the pilot and vehicle if the engine stalls. It is therefore a craft which can be considered as the safest of all aircraft. It can go where other aircraft, including helicopters, cannot go. <IMAGE>

Title: Mechanical system for transmitting motion from a motor to a wheel
Inventor: VILLANOVA ANGELO
IPC: F16C/
Filed: 1993-07-14
Granted: 1996-12-30
Abstract: The mechanical system makes it possible to transmit motion from a motor to a wheel which, during the motion, can turn through 360 degrees in both directions, unlike existing systems, which are very limited in the latter movement. This assembly is comprised of a conical pinion which, having received motion from a motor, transmits it to a toothed wheel which, made in a single piece, has seats in its upper part allowing for its rotation, while in the lower part there are two opposite toothings, the upper one receiving the motion from the pinion, the lower one transmitting it to a third toothed wheel, which is secured laterally to the end wheel and will furnish the initial motion of the motor to it. The latter will turn on a pin which, exiting in parallel with the wheel itself, will pass through the centre of the bell and of the fixed support, projecting from it in order to attach, for example, a steering wheel to give the desired direction. <IMAGE>

IPC: B23B29/034
Filed: 2001-12-14
Abstract: The invention relates to the mechanical engineering and may be used in different metal-cutting machine tools: lathe, boring, drilling, milling. The boring head includes a body, provided with a handle and fixed onto a shaft, as well as a tool-holder movement mechanism enclosed into the body. Onto the shaft it is made a collar with inclined surface, directed towards the tool-holder movement mechanism, containing a double satellite gear unit, mounted onto the shaft by means of a spherical bearing bush. One gear ring thereof engages into mesh with the immobile gear-wheel, which is fixed into the body from the collar inclined surface end with the possibility of contacting the face of the satellite gear unit hub with it, and the second gear ring thereof engages into mesh with the mobile gear-wheel. Into the hub of the satellite gear unit from the end of engagement with the mobile gear-wheel there is made a pit, with the inner lateral wall of which come in contact the balls, placed into the annular groove, made on the lateral surface of the nut, installed with eccentricity onto a screw, freely mounted onto the shaft, at the same time the screw head is made conic and placed outside the hub of the satellite gear unit. Into the hub of the mobile gear-wheel there are radially installed spring-loaded tool-holders, each of which is made in the form of a cylindrical rod, onto one end of which it is placed a bearing ball, coming in contact with the screw head, and onto the other end thereof it is placed a rolling ball. The tool-holder is mounted onto the boring head face with the possibility of carrying out the longitudinal feed by means of some pins, one end of each of which being rigidly fixed into the tool-holder, and the other end correspondingly is freely placed into the pit, made as an Archimedean spiral onto the face of the mobile gear-wheel.Claims: 1Fig.: 2

Inventor: MORI PETER
IPC: B66B5/22
Filed: 2002-10-25
Abstract: A braking device acts on a guide rail and consists of a housing that is arranged at an elevator car yoke and serves as a support for spring packets and/or for adjusting packets. The housing also serves as a support and guide for chock guide elements that in turn retain and guide brake chocks with brake linings. Pushrods engage at one end at the brake chocks, and at the other end are pivotably connected to an actuating fork. Upon braking of the elevator car, the actuating fork is moved at the pushrod end in the direction of the braking device. The guided brake chocks with the brake linings slide in the braking device. At the same time the brake linings are moved at the guide leg of the guide rail. The brake chocks are moved in the braking device and the spring and adjusting packets are stressed, whereby a braking force for stopping an elevator car or a counterweight is generated.
