Patent ES-467190-A1 (ES)
Title: Attachment of proteins to inert particles
IPC: G01N33/545
Filed: 1978-02-21
Abstract: A two-step process for achieving a covalent bond between latex polymers and immunological substances, the first of which involves reacting latex particles having a reactive carboxyl group with a diamine in the presence of an appropriate carbodiimide as the condensing agent. The resulting product, which can be designated as the modified latex, is an amide terminating in primary or secondary amino groups. This product is then reacted with the appropriate immunological reagent such as an antigen or antibody modified if necessary to contain amino groups, in the presence of a bifunctional aldehyde to result in the condensation of the amino groups of the immunological reagent to the amino groups of the modified latex via an intermediate aldehyde bridging moiety.

Patent ES-478588-A1 (ES)
Title: Closed pressurized solar heating system with automatic solar collector drain-down
IPC: F24J2/46
Filed: 1979-03-13
Abstract: A closed pressurized solar heating system in which a solar collector is automatically drained of heat transport fluid independently of valve actuation or valve position. Undersized pipe return lines connect the solar collector to top, bottom and intermediate openings of a sump tank which is initially filled with the fluid, water, to a level between the top and intermediate openings. Drain-down automatically commences upon de-energization of a system pump, whereupon air from the top of the sump tank enters the pipe return line, breaking the vacuum existing within the flow path, and initiating fluid return to the sump tank. High flow rate embodiments with similarly automatic drain-down features are also disclosed. These embodiments employ flow diversion devices to divert fluid flow to undersized pipe return lines in communication with the sump tank during initial filling of the solar collector. After a predetermined time delay, fluid flow in the pipe return line is returned to oversized pipe sections which essentially bypass the sump tank and permit high flow rates.

Title: Rack steering mechanism
IPC: B62D5/22
Filed: 1979-10-23
Abstract: The invention provides a lightweight, economical rack steering mechanism comprising a booster pressure cylinder having a piston mounted on a toothed rack engaged by a pinion carried by an end closure element secured to the cylinder which has an end closure element at its opposite end.

Title: Blow molding clamp.
IPC: B29C49/06
Filed: 1982-03-16
Abstract: This relates to a blow molding system wherein a plurality of preforms are simultaneously blow molded within a mold set with the preforms being carried by one or more carriers which move first to a loading station to receive preforms, then through an oven to heat the preforms, then into a mold set wherein the plural preforms are simutaneously blow molded, then to an ejection station where the blow molded articles are discharged, and finally back to the loading station. There are two mold sets which are part of a clamp which operates sequentially to open and close each nold set with one mold set being closed as the other mold set is being opened. The carriers may travel either in a single continuous path for sequentially positioning at first one mold set and then the other, or there may be two continuous circuits for the carriers in which event the two mold sets of the clamp may be different. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
Patent ES-8303217-A1 (ES)
Title: Apparatus for the surface-treatment of buildings and ships.
IPC: B05B7/14
Filed: 1982-03-31
Abstract: In order to increase the efficiency of known compressed air projection methods, there is proposed, according to the invention, to provide the outlet nozzle (9), conformed in a known manner as a Laval tuyère, with a funnel-shaped element (12) defining a parabolic elongate chamber. For an underwater utilization, also in deep waters, it is further proposed to provide, between the compressed gas source (1) and the conduit leading to the outlet nozzle (9), an additional shunt conduit (30) for the compressed gas, adjustable and around the source of material to be projected. The compressed gas supplied through the shunt duct may, by appropriately adjusting the pressure, prevent water to penetrate in the parts of the projection device being under water. It is thus possible to keep free of water the supply pipe of material to be projected and the space between the projection nozzle and the surface to be treated. The material to be projected may reach the surface to be treated with a substantially higher energy.

Title: Variable sensitivity motion detector.
IPC: G08B15/00
Filed: 1984-11-07
Abstract: The motion detector of the present invention, together with associated AC switching circuitry form a lighting control system which turns on room lights when the room is occupied, and extinguishes the lights when unoccupied. The detector sensitivity or threshold is adjusted in response to the previously detected conditions, providing reliable indication of both entry and continued presence in the controlled area, and producing few false alarms. The present embodiment of the invention has two threshold levels of detection, the higher level being used to detect initial entry into the room. After entry is detected, the motion detector lowers the threshold to detect the weaker signals usually occurring for continued presence in the area of the detector. When the occupant leaves the area, the motion detector threshold or sensitivity returns to the original value after a timeout period.
