Patent EP-0251134-A3 (EP)
Title: Compositions for preventing graft rejection
IPC: A61P37/06
Filed: 1987-06-23
Abstract: The invention relates to means for preventing or for delaying the rejection of allografts in humans and for the alleviation of and for treating autoimmune diseases in humans. The pharmaceutical compositions which are suitable to attain the above ends ard based on heparin, on N-desulfated, on N-acetylated heparin or other suitable derivatives of heparin. The dosage which is effective is one which is substantially lower than that required for obtaining an anticoagulant effect in mammals. It is generally of the order of about 1 per cent to about 10 per cent of the anti-coagulant effective dosage of such compounds.
Patent EP-0269091-A3 (EP)
IPC: F15B21/044
Filed: 1987-11-25
Abstract: This invention relates to an improved 
hydraulic actuator such as those used to reciprocate 
the valve pin in an injection molding system. A small 
diameter hole (18) is provided through the piston (13). This 
allows a limited flow of hydraulic fluid from one side 
of the cylinder (12) to the other, but yet enables the 
piston to control the valve pin or other mechanism in the 
manner necessary. This small flow of hydraulic fluid 
provides for the escape of trapped air, relieves 
stagnation and excessive temperature build up in the 
fluid, and avoids the accumulation of sediment and 
corrosion.

Title: Electronic alarm clock
IPC: G04G13/02
Filed: 1989-04-05
Abstract: Electric alarm clocks such as, e.g, radio alarm clocks, awake the sleeper with the volume last set. However, because on the one hand the volume must be high enough in order to prevent the risk of oversleeping while, on the other hand, sudden awakening owing to noises which are too loud damages the human nervous system and psyche, it is difficult to set the optimum volume. Because, furthermore, the sensitivity of hearing and the depth of sleep fluctuate from day to day, it is never known in advance precisely what volume is optimum for waking. In order to achieve reliable and yet soft awakening, the volume rises from a presettable initial value to a presettable final value. It is particularly advantageous if it is also possible to set the time in which the volume rises from the initial value to the final value. It is determined in this way whether waking is more or less soft. Radio alarm clocks with and without cassette component, hi-fi installations with tuner, cassette component and CD player.

Filed: 1989-01-26
Abstract: A resistance temperature device for sensing the 
temperature of a surface (12) of for example a heat 
exchanger comprises a metal body (18) in use welded to the 
surface (12) and having a recess (26) mounting a resistance 
element (28) in contact with the surface (12). The leads 
(30,31) of the element pass through the body and are 
connected to those (34,35) of a sheathed cable (20) which is 
welded to the end portion (20) of the body (18). Means (38) 
e.g. high temperature cement thermally insulates the element 
(28) from the body (18) and, further, an intermediate 
reduced cross-section portion of the body (18) between the 
end (20) and the recess (26) inhibits heat transfer so as to 
thermally isolate the element (28) from the sheath (24). 
The element thus measures the temperature of the surface 
(12) and is not influenced by the temperatures of the body 
(18) or sheath (24).
