Abstract: The invention relates to a device for the optional guiding of at least one self-steering wheel of a trolley. According to the invention, the wheel is of the type that is mounted on a support that pivots around a vertical axis. The device comprises: a push bar which forms a dual-articulated steering member that can be accessed by the user; means for rotating a first clutch part about the vertical axis in response to steering member movements; and means which can be used at will to couple and uncouple the first clutch part in relation to a second clutch part which is solidly connected to the aforementioned support of the wheel, in response to other steering member movements. In addition, a coin-operated locking device for preventing the movement of the trolley is built into a casing which houses a transmission element of the guiding device and which is fixed to the push bar of the trolley.

Abstract: The invention relates to a solar energy concentrator-collector device including a stationary reflector-concentrator with reflector-concentrator modules joined to a stationary structure forming a matrix. Each reflector-concentrator module includes a frame and at least one reflective surface portion configured to reflect the sun's rays and concentrate them in a linear focus. The stationary structure is formed by frames fixed to supporting profiles. A mobile receiver includes a mobile structure supporting receptor elements parallel to the linear foci. A tracking mechanism is connected to several the supporting profiles and to the mobile structure in order to support and move the mobile structure on the stationary reflector-concentrator so that the receptor elements follow a path of maximum confluence of the sun's rays reflected by the reflective surfaces as the relative position of the sun changes.

Abstract: A roller ironing machine for articles of clothing includes a heated ironing roller supported, guided and rotated in a frame, a floating pressure roller parallel to and in contact with the ironing roller and endless belts mounted to satellite rollers to cover part of the ironing roller. Additionally, axial journals belonging to the floating pressure roller rest against inclined planes which are fixed to the frame such as to form an angle in relation to a plane that is tangent to the ironing roller and the floating pressure roller on the line of mutual contact. The journals rest against the planes with a force that includes a normal component derived from the weight of the roller, thereby producing a greater ironing force than the weight of the roller owing to the wedge effect provided by the opposing directions of rotation of the ironing roller and the floating pressure roller.

Abstract: This device comprises two U-shaped holders being arranged in an inverted-U arrangement, having their respective rear ends linked in a pin-jointed connection to the truck and having fitted to their front ends a mechanism being provided with supports by means of which the containers are grabbed in order to be lifted and tipped. This device is characterised in that the supports form an assembly being at its lateral, rear region linked in a pin-jointed connection to said mechanism by means of an obliquely diverging appendage. This appendage is linked in a pin-jointed connection to the end of an arm having its other end linked in a pin-jointed connection to a slide being apt to be slid along a guide being provided between the front ends of the U-shaped holders being arranged in an inverted-U arrangement. The arm is a telescopic arm.

Abstract: Said floating group comprises: a drum (20) aligned with a center line (M) which rotates within a wrapping bin (10) driven by a motor (32), and when it rotates it creates, by an effect of masses unbalance, an actual rotation axis (N) different from said center line (M); a counterweigh (40) of mass mCE associated to a front part of the bin (10) and a counterweigh (42) of mass mCT associated to a front part of the drum (20), where the ratio [mCT/(mCE+mCT)]×100≧55, said mass mCT either a given magnitude centered with said center line (M) or a very lower magnitude and in the form of one or more fluid rings (60), the stresses the floating group sustains resulting substantially reduced, it being for it made in a light construction.
