Abstract: 1. An improved device for preparing the ground by means of a transverse roller mounted on a tractor, adapted to flatten the ground in as uniform a manner as possible between the tracks of the wheels of the tractor, in which the roller (1) is pulled by a coupling (4) connected to the chassis (6) so that it is disposed underneath the tractor behind its front wheels (7B ), and the roller moreover is subjected to the action of a hydraulic operating system (9) which uses jacks (16A , 16B ) controlled by a control system adapted to allow the driver to move the roller to occupy either a raised transporting position or a lowered working position in which the pressure exerted on the ground is derived from the weight of the tractor, characterized in that the roller is situated substantially below the centre of gravity of the tractor, which permits an optimal distribution of the masses, and in that the control system comprises a damping circuit having a nitrogen storage vessel (26) connected to the thrust end of the two jacks (16A , 16B ) of the hydraulic operating system (9) acting on the roller, this circuit comprising, in addition to this storage vessel and a manometer (23) allowing its pressure to be displayed, a valve (22) adapted to connect this thrust end of the jacks and this storage vessel (26) in parallel to the pressure distributor (21) of the tractor, as a result of which the control system is adapted to allow preset control of the pressure exerted by the roller on the ground before work begins by opening the valve (22), then applying a pressure to the damping circuit and the thrust end of the jacks until a chosen pressure is obtained, then closing the valve, and it is also adapted to automatic application of this preset pressure on the roller when the latter is placed on the ground to work on the ground, the storage vessel (26) storing the oil driven back at the thrust end of the jacks in the raised transporting position and restoring it at this end in the lowered position.

Abstract: The device to prevent a boom (5) colliding with a loading apron (9) of a cutting machine (1) comprises a self-contained line (14) which is laid between boom (5) and loading apron (9). A pressure sensor (17) is located close to the lower end (16) of this closed line (14), which is filled with liquid. The signals from the pressure sensor (17) are fed to an electronic analysing system. Depending on the pressure value measured, which is proportional to the vertical distance between boom (5) and loading apron (9), an alarm is activated or action is taken in the control system of the hydraulic drive of the boom (5) or loading apron (9). The drive of the boom (5) in the direction of double arrow (6) in the vertical direction is effected via hydraulic cylinder-piston units (7), whereas the drive for pivoting the loading apron (9) in the direction of double arrow (10) is ensured by hydraulic cylinder-piston units (11). <IMAGE>

Abstract: An optical substantially afocal beam expander has a negative lens element (1) spaced from a positive lens element (2). The lens elements are of different materials with respective coefficients of refractive index change with respect to temperature such that the effect of a temperature change on one element is at least partially compensated by the effect of the temperature change on the other element. The beam expander is therefore substantially athermalised with respect to afocality.

Abstract: PCT No. PCT/AT87/00026 Sec. 371 Date Dec. 14, 1987 Sec. 102(e) Date Dec. 14, 1987 PCT Filed Apr. 14, 1987 PCT Pub. No. WO87/06183 PCT Pub. Date Oct. 22, 1987.During the essentially continuous process for producing a polymer plastic, especially a foil or thin sheet (38) containing polymethyl methacrylate, a highly-viscous polymer plastic is first applied to a flat carrier inside a separating layer, whereby regions of the support surface remain free, in the manner of a surface pattern. Next a low-viscosity polymerizable monomer and/or pre-polymer (30) are cast on to this separating layer in such a way that it forms, over the separating layer, a liquid layer, onto which is applied a flat, thread-like support material (32), which may advantageously have a decorative surface and into which the support material (32) is then embedded or impressed. Next after the possible application of further layers consisting of high and/or low-viscosity plastic, especially inside a second separating layer, the thus produced material coating is transferred to the foil (38) or thin sheet, accompanied by polymerization of the plastics contained therein. In this process, the separating layers prevent the support material from coming close to the surfaces of the sheet (38) to be produced, since the highly-viscous plastic contained in the separating layers does not penetrate the porous support material.

Inventor: BOUDEWIJNS ARNOLDUS JOHANNES J
IPC: H03L1/00
Filed: 1988-06-02
Abstract: The invention relates to an oscillator circuit comprising an oscillator (OSC) with a CMOS gate. A suitably proportioned CMOS gate consumes power only when its gate output, assumed to be capacitively loaded, is charged. Using this fact, a relation can be deduced between an oscillation frequency of the oscillator (OSC) and a ratio of the voltage (V₂₂) across the CMOS gate and the conduc­ted current. The invention incorporates the actual oscillator (OSC) in a circuit so that this ratio remains substantially constant and becomes substantially independent on temperature variations. To achieve this, the oscillator (OSC) is included in a first current branch (II-1) having a first current source (20), a second current branch (II-2) comprising a second current source (21) being arranged parallel to the first current branch (III-1), in series with a resis­tance (R), the current sources (20, 21) supplying currents with a fixed ratio. The current branches (II-1, II-2) are coupled to one another by means of control means (22, 23) for controlling the current sources so that the ratio of a voltage (V₂₂) across the CMOS gate and a voltage (V₂₁) across the resistance (R) is constant.
