Title: Apparatus for marking (identifying) lines
IPC: F16L55/00
Filed: 1995-07-31
Granted: 1997-04-25
Abstract: An apparatus in the form of an annular disc for marking lines, in particular cables, consists of a basebody 1 which has a slot 6, is in the form of an annular disc and has a bead 2 on its outer circumference 7. The slot 6 leads in the form of a wedge tapering from the outside to the inside as far as an opening 5 in which a line is held when the apparatus is fitted to the line. The annular basebody 1 is provided with corrugations 11, 12, 13 opposite the slot 6, which become narrower and flatter towards the outside and, at the outside, merge into the bead 2. Owing to the region 10 which is elastic by virtue of the corrugations 11, 12, 13 and is opposite the slot 6, the basebody 1, which is in the form of an annular disc, is expanded elastically when the apparatus is pushed onto a line, and then automatically springs back, with the apparatus being held firmly on the line. Any desired markings can be applied or are applied to the basebody 1 which is in the form of an annular disc. <IMAGE>

Title: Method and device for filling the edge joints of insulating glass panes with sealing compound
IPC: E06B3/673
Filed: 1990-10-15
Granted: 1995-08-25
Abstract: When the edge joint of an insulating glass pane is being filled with sealing compound, the speed of the relative movement between insulating glass pane and filling nozzle is changed in such a way that the desired level of filling of the edge joint remains constant even if the depth of the edge joint changes and/or the delivery rate of a sealing compound changes. The amount of sealing compound which is delivered to the filling nozzle per unit time is determined with the aid of a sensor which, between the metering device and the filling nozzle, is assigned to the line for sealing compound. Downstream of the metering device a restriction is arranged in the line for sealing compound, which restriction can be adjusted in steps in terms of its restricting action, so that it is possible to avoid excessive changes in the relative speed by changing the delivery rate of sealing compound. <IMAGE>

Patent FI-92513-B (FI)
Inventor: AULBERS ANTONIUS PAULUS
IPC: E05B9/08
Filed: 1990-04-09
Granted: 1994-08-15
Abstract: An "electronic" lock has a thrower 5 for extending and retracting the bolt when turned by a key carrying a proper code. Turning of the thrower through a sufficient distance to shift the bolt is normally blocked by a dogging lever 20 with which the thrower lug 6 abuts. The thrower lug also sweeps a cam track 28 on a second lever 26 so as to pivot the latter during initial turning movement of the thrower away from its rest position. The second lever carries an electromagnet 30. While the electromagnet remains de-energized there is no interaction between the two levers so that the second lever 26 can pivot independently of the first 20 and turning of the thrower remains limited. When a correct key code is detected, however, the electromagnet is energized to hold the two levers together. Initial turning of the thrower thereby causes the second lever to carry the dogging lever away from its blocking position and thus free the thrower for 360 DEG  movement.
