Title: Method for the heat treatment of aluminum strip
IPC: C22F1/04
Filed: 1979-07-14
Abstract: During the process in which an aluminum strip is moved in a floating mode, the strip is first heated, then cooled and annealed. When the aluminum strip is cooled, the strip is moved while being curved into a wave-like form toward the moving direction thereof. The aluminum strip is curved in a manner as described, and as a result, the aluminum strip increases in antibuckling stress. The increased antibuckling stress overcomes a thermal stress produced in the direction of the width of the aluminum strip during the process of cooling. Accordingly, the aluminum strip is cooled without formation of wrinkle parallel to the longitudinal direction of the strip.

Patent ES-8204070-A1 (ES)
Title: Method of and apparatus for optimising the operation of an internal combustion engine.
IPC: F02D41/14
Filed: 1981-07-07
Abstract: I.C. engine performance is optimised by imposing a cyclically fluctuating trim on a control input in synchronism with engine operation and measuring the effect of the trim on engine speed. A store (16) holds an average value of the control input (eg. spark timing) and the trim is applied by a calculator circuit 14 to increment and decrement the counter content periodically in synchronism with the engine. A counter (18) counts clock pulses in a sequence which yields a residual count enabling the content of the store (16) to be changed if this residual count indicates that advancing or retarding timing will increase engine speed.

Title: Connection for fluid lines and hoses
IPC: F16L37/00
Filed: 1981-08-17
Abstract: A connection for use with lines and hoses is designed for joining up such lines with a fluid distribution unit. The connection has a body and an endpiece at one end which may be joined up with the distribution unit and undone therefrom and at the opposite end of the body there is a female endpiece, the two endpieces being joined together fluidwise by a hole running through the body and through the endpieces. In this hole, a spring-loaded stopper is placed so that it may be axially moved out of a shut-off position on pushing a piece of line or hose into the female endpiece against the force of the spring. The female endpiece has gripping fingers, separated by narrow cutouts, such fingers having a common outer conical face on which a gripping ring may be moved axially between a gripping position and a line released position. Furthermore, the stopper and the inner wall of the body have inwardly running shoulders for limiting sliding motion of the stopper into its opened position. A gasket ring, seated in a ring-like pocket in the wall of the hole through the connection, is designed for resting fluid-tightly against the outer face of the line or hose and its side turned towards the first endpiece encases liquid-tightly a collar on the stopper in the closed condition of the connection.

Title: Reversing door ratchet.
IPC: F23K3/00
Filed: 1981-09-25
Abstract: A reversing ratchet lever assembly for driving a bolt or other threaded element to be turned selectively in clockwise and counterclockwise directions about a lever axis. The assembly has a housing that defines a bore coaxial with the lever axis and that receives a drive head for the bolt or other fastener. The drive head has radial external ratchet teeth that are adapted to be engaged by a double pawl pivotally mounted in the housing. The pawl is adapted for movement between forward drive and reverse drive engagement with the ratchet teeth and has an intermediate disengaged position. The assembly is operated by a lever handle adapted to be grasped by an operator. The handle has an inner end received in and retained in the housing for pivotal movement about a longitudinal twist axis located perpendicular to the lever axis. The inner end of the lever handle is operatively associated with the pawl and is adapted to move the pawl to its forward drive position when the handle is twisted in one direction and to its reverse drive position when the handle is twisted in the opposite direction. The handle is biased to a neutral position so that the pawl is disengaged unless the handle is positively twisted in one direction or the other.
Patent ES-8206762-A1 (ES)
Title: Liquid fuel injection pumping apparatus
IPC: F02M41/14
Filed: 1981-11-11
Abstract: A liquid fuel injection pumping apparatus of the rotary distributor type has stop means defined by complementary inclined surfaces on a rotary portion, coupled to a drive shaft and on the cam followers associated with the pumping plungers. The cam followers and the distributor member are axially movable to vary fuel quantity. In order to vary the initial rate of fuel delivery one or a reduced number of plungers only is arranged to deliver the initial flow of fuel. This is achieved by axial adjustment of one or more cam followers relative to the distributor member so that the associated plunger or plungers can move outwardly further during the filling stroke of the apparatus and will therefore be moved inwardly before the remaining plungers. Alternatively an axially movable part may be provided on said rotary portion.

IPC: A61K41/00
Filed: 1982-06-11
Abstract: A method and system are disclosed for externally treating human blood, with the objective of reducing the functioning lymphocyte population in the blood system of a human subject. Blood is withdrawn from the subject and passed through an ultraviolet radiation field in the presence of from about 1 nanogram to 100 micrograms per ml of blood, of a dissolved photoactive agent capable of forming photo-adducts with lymphocytic- DNA, mobile cortisone receptors or antigen sites to thereby effect covalent bonding between the photoactive agent and the same, thereby inhibiting the metabolic processes of the lymphocytes or complexing them and thereupon returning the irradiated blood to the subject. The withdrawn blood may be formed into an extracorporeal stream 18 and flowed through a treatment station 24 whereat the irradiation is effected, as for example by exposure to UV radiation source 30 and such flow process may be conducted on a continuous basis. At least portions of the treated blood may then be separated, e.g. by a continuous centrifuge 44, before returning 14 the remaining diverted blood to the subject.
