Title: Automatic and auto-adaptive fusion-welding process, and device for carrying out this process.
IPC: G05B19/42
Filed: 1981-02-12
Abstract: The invention relates to an automatic and self-adapting process for fusion-welding a joint between two surfaces, with the aid of a welding head which essentially comprises a joint detector and a torch supported by a carrier mobile along the joint. This welding head is mobile in rotation about a main axis related to the carrier and substantially perpendicular to the plane tangential to the surfaces to be welded at the location of the joint, and mobile in translation along this main axis. The torch and the detector are mobile in rotation about a secondary axis related to the head and parallel to the main axis and the torch is able to pass through the main axis in the course of its rotation about the secondary axis. A reference direction for all the degrees of freedom of the head is defined when the above-mentioned axes as well as the axes of the torch and the detector are in the same plane. This process is characterized in that it consists: in recording the electric voltage corresponding to the angular position of the reference direction in measuring, in the course of welding and for each position of the holder, the angle of the detector with respect to the reference direction of the head, when the detector is above the joint in correcting, during the operations following the trial operation, the angular position of the torch when the latter occupies the position previously occupied by the detector, by an angular displacement which is a function, on the one hand, of the angular deviation of the detector with respect to the corresponding reference direction at this point of the joint and, on the other hand, of the speed of displacement of the head on its path. The invention relates also to an automatic device for carrying out this process.

Patent ES-8201747-A1 (ES)
Title: Memory write error detection circuit
IPC: G06F12/16
Filed: 1981-03-26
Abstract: A circuit for the detection of write errors in a memory with selectable byte addressing. The memory is capable of selectively writing bytes within a memory word by decoding control signals and address signals received from a processor. The decoder and transmission path of the control signals are checked by the processor generating incorrect parity for the bytes which are not to be written. The memory decodes the control signals, checks the parity of the bytes, and generates a write parity error if the decoder selects a byte with incorrect parity to be written. If the memory malfunctions and spuriously writes an unselected byte, this fact will be detected when the unselected byte is read. The memory checks each byte read for parity, and incorrect parity causes the memory to transmit a read memory error to the processor.

Title: Liquid-solid separation utilizing pressure rolls covered with elastomeric layers.
IPC: B30B9/24
Filed: 1982-02-16
Abstract: A method and apparatuses for expressing the liquid phase from a wet mixture such as a clay-like mixture includes a primary roll (12, 104) with a plurality of smaller pressure rolls (13, 112-118) biased against its surface at circumferentially spaced intervals and at increasing pressures. The primary roll and at least the upstream one (112) of the pressure rolls have a thick outer covering of a substantially deformable elastomeric material. A pair of opposed filter belts (22, 23 or 142, 144) are trained about the primary roll and means are provided to feed the wet mixture between the belts to carry the mixture successively through the nips between the primary roll and the pressure rolls. The mixture is initially subjected in the first nip to a relatively gradual rate of increase in pressure and in subsequent nips is subjected to progressively steeper rates of increase in pressure adapted to the different flow behavior of the mixture caused by the increasing solids content of the mixture. In one embodiment all of the pressure rolls (112-118) are covered with equally thick elastomeric layers of equal hardness, and the first roll (112) is biased with a predetermined relatively low pressure to initially subject the wet mixture to said relatively gradual increase in pressure. In an alternative embodiment intended for wetter mixtures, the rolls (112'-118') are covered with equally thick layers which increase in hardness in the direction of travel of the belts. Specially fabricated belts and edge seals are disclosed.

Title: Clutch plate
IPC: F16D13/64
Filed: 1983-11-18
Abstract: The clutch plate of a friction clutch in a motor vehicle has a first damping unit whose input element carries the friction linings and whose output element is a first hub having a radially outwardly extending first flange, and a second damping unit whose input element constitutes the input element of the first damping unit and whose output element has a second hub surrounding a portion of the first hub and having a second flange extending radially outwardly therefrom. The first damping unit has first coil springs in registering openings of the first flange and the input element, and the second damping unit has second coil springs in registering openings of the input element and second flange. The springs of the first unit oppose rotation of the linings relative to the first hub during a first stage of angular movement of the input element relative to the first hub, and the springs of the second unit cooperate with the springs of the first unit to yieldably oppose further rotation of the linings relative to the first hub. The extent to which the springs of the first unit alone oppose rotation of the linings relative to the first hub is determined by the circumferential play between the external teeth of the first hub and the internal teeth of the second hub.
