Patent ES-391811-A1 (ES)
Title: Conveyor systems
IPC: B61B10/02
Filed: 1971-05-22
Abstract: A power and free conveyor has a downwardly inclined section of its trolley track provided with a holding station at which is disposed a stop mechanism. The mechanism includes a stop arm which normally occupies an operative position in which it projects over the trolley track to depress into inoperative positions respective driving dogs and respective holdback dogs of trolleys on the track. In their operative positions, these driving dogs are engageable by pushers carried by an endless power chain running in a chain track spaced above the trolley track. The stop arm arrests a trolley by abutting the depressed holdback dog of the trolley. The mechanism also includes a second member which normally occupies an operative position in which it projects under the trolley track to restrain forward movement of a trolley at the holding station. On receipt of a signal from the next holding station along the track that the preceding trolley is clear of this next station, a pneumatic piston-and-cylinder device moves the stop arm into its inoperative position to cause a pusher to engage the driving dog of the detained trolley, and another such device allows the second member to move forwardly gradually into its inoperative position to cause a smooth forward movement of the trolley under the action of the pusher.

Patent ES-433104-A1 (ES)
Title: Position measuring transformer
IPC: G01B7/00
Filed: 1974-12-19
Abstract: An improved radio frequency transformer apparatus for detecting positional changes between a moving and a fixed element is disclosed. The system operates in the high frequency range (on the order of 5 megahertz) and utilizes a centered tapped pickup coil in conjunction with an elongated primary serpentine coil for detecting the null points in a signal which is inductively coupled to the pickup coil as it passes along the elongated serpentine transmitter coil or primary. The use of the null point as the sensing or trigger point simplifies the circuitry required and reduces the cost involved in building the position detecting transformer. The use of the high frequency signals reduces the size and complexity of circuits and circuit elements and enables the entire primary oscillator and detector amplifiers to be embodied in integrated circuit chips for positioning directly on circuit board apparatus. In addition, this design allows a fairly wide variation in spacing tolerance between the transmitter and the detector coils without inducing positional error indications between the moving and fixed elements. This further reduces the cost by lowering the precision required in constructing the device.

Title: Hydroxyalkyl hydroxy-aromatic condensation products as fuel and lubricant additives
IPC: C07D311/00
Filed: 1975-04-04
Abstract: Condensation products made by reacting an alpha-hydroxyalkyl hydroxy-aromatic compound also having at least one non-fused hydrocarbyl substituent with at least one olefinic nitrile, carboxylic acid or carboxylic acid derivative are useful as additives for fuels and lubricants.

Products made from hydroxymethyl alkyl-substituted phenols and alpha , beta -olefinic acid derivatives such as maleic anhydride are particularly useful. Similarly useful post-treated products can be made from these condensation products by further reaction with alcohols, amines, metal salts or metals.

Patent ES-443134-A1 (ES)
Title: Method and apparatus for manufacturing a helically finned heat exchanger
IPC: F28F1/36
Filed: 1975-12-02
Abstract: A method and apparatus is disclosed for the manufacture of a continuous heat exchanger tube including helically winding a spine fin material on the outer wall of a base tube member. A preselected portion of the spine fin material is secured against movement relative to the base tube member. The heat exchanger is then severed in the secured portion so that a section of the secured portion is arranged at each end of the severed heat exchanger. The secured severed end sections are effective in maintaining the intermediate portion of the spine fin material from unwinding and, as a result, in heat transfer relationship with the base tube member.

Title: Hydrocarbon conversion
IPC: C10G35/085
Filed: 1978-07-11
Abstract: Hydrocarbon hydroconversion, especially hydrocarbon reforming, using catalysts whose supports have been prepared by a sol-gel process. For hydrocarbon reforming, it is preferred that the primary particles used to prepare the porous gel should have been prepared by a vapor phase condensation method, for example flame hydrolysis and that the support should have a narrow pore size distribution. The process produces much less gas by hydrocracking at given aromatics yields than comparative processes using conventional catalysts.

Patent ES-476308-A1 (ES)
Title: Self-priming pump
IPC: F04D9/04
Filed: 1978-12-22
Abstract: The invention relates to a self-priming centrifugal pump that consists of at least one fully-loaded pump or turbine stage with a horizontal shaft and one priming or ventilator stage that is fixed to the same shaft outside the main delivery stream, in the form of a lateral channel or liquid ring pump. In certain specific applications there is no flow through the ventilator stage during normal operation of the pump, and for this reason the ventilator stage is not cooled. The ventilator stage is cooled by virtue of the fact that the suction side of this stage is not only connected to the suction area of the fully loaded turbine stage, in which the gases that are to be removed usually collect, but is also connected to the pressure side of the pump, so that during normal operation a stream of liquid that has a cooling action is formed, and this passes by the suction opening of the ventilator stage.

Patent ES-8203218-A1 (ES)
Title: Method of making organic grafts.
IPC: C08J7/14
Filed: 1981-03-30
Abstract: The organ transplants are intended to be used as a replacement (prostheses) for organs or parts of organs, for examples arteries or veins, which have undergone pathological change or are functionally impaired. The organs, which are taken from a fish, bird or higher mammal, are subjected to crosslinking of the amino groups and of the alcoholic hydroxyl groups of the peptide chains of the intercellular matix by means of a di-, tri- or poly-carboxylic acid. It is advantageous subsequently to treat the crosslinked product with a dialdehyde, in order to bind amino groups which have not reacted, or to free the crosslinked product from material which potentially may act as an antigen, by hydrolysis with ficin, papain or a protease having a smaller action. After the hydrolysis, a comprehensive crosslinking is appropriately ensured using a dialdehyde or a di-, tri- or poly-carboxylic acid. The resulting prostheses are distinguished by chemical stability, biophysical and biochemical properties similar to those of the natural material and the absence of rejection reactions.
