Patent DE-4019770-A1 (DE)
IPC: E01B9/14
Filed: 1990-06-21
Abstract: For the protection of sleeper bolts 4 against corrosion, the plugs 2 for anchoring the sleeper bolts in the sleeper 1 are filled before track installation - usually already during manufacture - with a corrosion-protecting viscous filler material 3. The incompressibility of such filler materials 3, which have the characteristics of a high-viscosity liquid, can produce high forces in the plugs 2, acting perpendicularly to the sleeper axis, during sudden mechanical screwing-in of the sleeper bolts 4, which forces can split the sleeper. In order to prevent this, it is proposed to use as a corrosion protection agent filler materials 3 which are interspersed with cavities or pores. <IMAGE>

Title: Co-ordinate input unit for CRT screen - uses integrated switch system for resolution change and selection purposes
Inventor: MATSUMOTO MIKIO
IPC: G06F3/0354
Filed: 1991-03-05
Abstract: The co-ordinate input unit consists of a housing (3) which contains a protruding, hand operated sphere (4).
