Patent ES-8103474-A1 (ES)
Title: Halogen incandescent lamp
IPC: H01K1/56
Filed: 1980-06-27
Abstract: In halogen incandescent lamps with bromine as the halogen and having a tantalum getter to absorb any free oxygen, the getter also absorbs bromine at high operating temperatures and affects the tungsten-bromine cycle adversely. Tantalum alloyed with tungsten in a weight ratio range of 9/1 to 1/9 has a very much larger affinity to oxygen than it has to bromine. As a result of this the alloys are excellently suitable for use as an oxygen getter in tungsten/bromine cycle lamps.
Patent ES-8105658-A1 (ES)
Title: Automatic change-over system for liquid dispensing system
IPC: F16K11/087
Filed: 1980-07-24
Abstract: An automatic change-over system for stock rotation of liquids packages in plural collapsible bag-type reservoirs including an improved automatic change-over valve is described. The bag-type reservoirs are divided into primary and secondary groups, the primary group containing a supply of liquid product which is currently being dispensed and the secondary group containing a supply of liquid product which is held in reserve. An automatic change-over between the primary and secondary groups of bag-type reservoirs is effected in response to a vacuum created by an empty condition in the bags in the primary group. A pressure change in the system results from the deflation of the empty bag-type packages which switches the change-over valve. Thus, the change-over is caused by the characteristics of the flexible bags containing the liquid being dispensed and the valve mechanism which connects the primary group, the secondary group and a dispensing pump together.

Patent ES-8105564-A1 (ES)
Title: Method and apparatus for compensation during ultrasound examination
IPC: G01S7/52
Filed: 1980-09-02
Abstract: The time-gain function of an ultrasound receiver for medical examinations is modified to compensate for different attenuation characteristics in body structures. The slope of the time-gain function is increased at times associated with pulse transmission through the highly attenuating body wall and may be decreased at times associated with pulse transmission through fluid filled body structures. The time-gain compensation, in combination with probe focus compensation and a highly linear receiver transfer function provides sharply increased diagnostic quality. The location and attenuating characteristics of body structures may be determined from a prior knowledge of their depth within the body or from distinctive signatures in ultrasound echos.
