Patent ES-486366-A1 (ES)
Title: Tube and stopper for blood-sampling systems.
IPC: B65D51/16
Filed: 1979-11-27
Abstract: An evacuated blood-sampling tube (1'') has a stopper with a skirt (43) which fits over the open end of the tube neck (1''a). The stopper has a central plug (48) surrounded by an annular groove (45), so that when the stopper is fully pushed on a dual-sealing effect is provided by the plug (48) fitting in the tube end and a sealing portion (43') of the skirt gripping about the tube neck. The stopper can be pulled out to a venting position, in which an axial groove (47) in the skirt communicates the interior of the tube with the exterior, to facilitate processing of the tube sample, including pipetting, with the tube stoppered. The tube may have a bead (2'') which engages the annular groove (45) in the sealing position and engages in another annular groove (46) in the stopper skirt to define the venting position. The axial groove (47) may be filled with an aseptized gas-permeable filtering material (49).
Patent ES-486528-A1 (ES)
Title: Continuous process and apparatus for adsorbent bleaching of triglyceride oils
IPC: C11B3/10
Filed: 1979-12-03
Abstract: Triglyceride oils are bleached rapidly and efficiently in a continuous system wherein a stream of the oil is preheated to bleaching temperature and is introduced into a mixing zone in such manner as to provide a swirling motion, bleaching adsorbent containing moisture is added to the surface of the swirling hot oil and water vapor or steam derived from the moisture in the adsorbent forms a protective atmosphere above the surface of the oil to protect it from oxidation. The oil-adsorbent mixture is pumped continuously from the mixer to a bleaching zone consisting of one or more static mixers, which may be unobstructed pipe sections, under flow conditions providing an average residence time of approximately one minute. The flow regime in the bleaching zone may be laminar or turbulent. Optionally, the oil-adsorbent mixture may flow continuously from the mixing zone to a vacuum dryer where it is deaerated and dried to optimum moisture content for bleaching prior to being pumped to the bleaching zone. Total time through the system may be in the order of less than three minutes. The advantages include simplicity of the operation, savings in time and ease of changing feedstocks.

Title: Method of multi-bead welding of two workpieces and apparatus for carrying out the method
IPC: B23K9/028
Filed: 1979-12-18
Abstract: An apparatus for multi-bead welding of two rotating workpieces comprises a flat filler wire holder which can be introduced into the gap between the workpieces and which is periodically pivoted forth and back at substantially constant angular velocity between the two sides of the gap. The pivoting is effected by a motor which is started when a cam rotating in synchronism with the workpieces actuates a stationary signal generator. The cam is provided on a cam disc which is driven through a friction coupling and which, on each revolution, is arrested by a pawl during a period determined by an adjustable timer. The timer is started when the cam actuates a stationary signal generator mounted shortly in advance of the pawl, and after the expiry of the period of the timer the pawl is retracted so that the rotation of the cam disc can continue. The pawl is again advanced to operative position when the cam actuates the first mentioned signal generator.

Patent ES-8702646-A1 (ES)
Title: Method of sequentially firing electronic-delay fuses.
IPC: F42D1/06
Filed: 1984-12-21
Abstract: For the chronologically staggered initiation of a plurality of electronic explosive delay detonators connected together with a blasting detonating machine, a signal current produced in each explosive detonator by signals sent by the blasting detonating machine, for example an impulse sequence, is integrated up in order to establish the delay time and, for carrying out of the delay, is integrated anew or integrated down to equality of the integrals or of the starting values. According to the invention, the integrating up begins in all explosive detonators simultaneously, with the end of the integrating up being controlled by signals from the blasting detonating machine. This end and accordingly the time period can be the same for all explosive charge detonators, while the two signal currents are possibly the same with the relative differences of the delay times being determined by the ratio of the signal currents which are different with setting and subsequent carrying out of the delay, or the end points of the integrations up or are different for each detonator. For increasing the safety, before the setting of the delay time, an impulse sequence with determined form is sent out from the blasting detonating machine and checked in each electronic explosive detonator so that the setting of false delay values by spurious signals is avoided. An energy storer in each explosive detonator is charged up only after successful checking of the impulse sequence at a value sufficient for initiation of the detonation.
