There are disclosed an automatic gear change control apparatus for an automobile and a method of controlling such apparatus. A rotational output (101) of an internal combustion engine (1) is connected to drive wheels (6) of the automobile and a load device (4). When a gear shifting-up of an automatic transmission (2) is to be effected, the load applied by the load device (4) is increased, or the l...

The invention relates to mammographs which make it possible to obtain a radiograph of the breasts. It consists in connecting the compression cushion (205) of a mammograph to the moving carriage (206) which drives it via a stationary piece (101) and a moving piece (102), which are themselves connected to a system of hinged parallelograms (104, 105). A spring (203) holds these parallelograms substan...

The rotary printing machine is provided with a feed which places any imperfect sheets on a stack which is separate from the stack of satisfactory sheets. The feed consists of endless chains (6,7) which transfer the imperfect sheets from the guide drum (1) to a first stack (11.1) and then transfers the sheets to the main stack (11). The transfer feed has an endless belt which is installed in a slid...

In a clamping device with a gap (12) for a thread (30) at the foot (14) of a spindle (16) of a spinning machine, at least some (20) of the elements (22a, 22b) forming the gap (12) are moved away from another element (22b, 14) under the effect of a centrifugal force (F), with the result that a gap (12), in which a thread (30) can lie, is widened. The thread (30) is thereby released and can move awa...

Disclosed is a magnet which is composed mainly of magnetic powders expressed by R-T-B (R is Nd or that partially replaced with rare earth elements and T is Fe or that partially replaced with transition metals.) and a chelate resin or a chelate resin mixed up with other synthetic resins. The magnet is markedly improved in deterioration caused by oxidation and corrosion.

A method for recycling PET beverage bottles comprises the removal of the contaminants with the use of supercritical carbon dioxide.

Interpolated piece of furniture consisting of the coupling of at least two elementary pieces of furniture (52a, 52b), each of them having a supporting part (54a, 54b) and all supporting parts being at equal height from the floor and each of them being formed by a plurality of elongated elements (58a, 58b) defining separation intervals (60a, 60b) which are substantially occupied by the correspondin...

Date Dec. 9, 1993.The invention relates to a extrusion die tool for producing a hard metal or ceramic rod with at least one twisted internal bore (14). The nose (3) of the nozzle (2) has a smooth cylindrical channel (4). A bearer (6) is fitted coaxially inside the ...

The novel installation for pressure dewatering of sludge contains an elongate pressure vessel which is fitted with at least one filter candle orientated parallel to the axis. The wall of the pressure vessel is covered with a filter drum through which flow passes outwards. The discharge of the dewatered sludge is opposite the feed so that the sludge moves through the pressure vessel along the filte...

In a method for reducing the bit error rate in the transmission of digital data by radio by means of an m-channel radio system, the bit error rate is reduced according to the invention in that first the transmitted data signals are extracted from the received signals with carrier in the individual m receiving channels, then the data clock rate is determined and the data signals and the data clock ...

The reliability and availability of a data transmission radio system between at least one mobile station and n fixed base stations arranged along a route are improved according to the invention by dividing the n base stations into m groups where 1

The invention relates to a sun shade with a material covering. Despite the shade provided by it, it can still become very hot under such a sun shade, which means that there is a requirement to make further cooling possible here. For this purpose, the invention specifies equipping the sun shade with a liquid reservoir (5) from which at least one liquid-conducting line extends, which distributes liq...

The invention relates to a polyurethane moulding composition containing a polyol component and an isocyanate component. The polyol component has a mean molecular weight of from 2500 to 4500, and the composition also contains a siloxane compound as a solvent.

A polyester film contains a polyester having an intrinsic viscosity (IV) in the range from 0.65 to 0.8 and an antioxidant. The polyester has an endothermic high temperature peak at a temperature of (A) DEG C and an endothermic low temperature peak at a temperature of (B) DEG C, both peaks being measured by differential scanning calorimetry (DSC), and the value of (A - B) is in the range from 25 DE...
