Patent DE-3908473-A1 (DE)
Inventor: BAUER HELMUTH
IPC: A47D1/02
Filed: 1989-03-15
Abstract: Prior art highchairs can be collapsed to take up little space for transport purposes only to a limited extent and erecting them is often laborious. The high chair of the invention is noteworthy in that it is highly stable in the open position and, despite the cranked upper bearing and supporting sections (1'') carrying a highchair seat (23), can be collapsed into a transport position requiring little space by rotating the ends of the bearing and supporting sections (1'') in a spindle movement, viewed from above, and thus the highchair seat (23) can be turned in upon itself and collapsed into a compact shape.
Patent DE-3911376-A1 (DE)
Inventor: GOUGH REX MALCOLM KENNETH
IPC: B43M5/04
Filed: 1989-04-07
Abstract: A transport means for driving an envelope in an inserter machine includes a driven roller 54, an idler roller 72 which moves into and out of engagement with the driven roller, and a clamp eg fingers 70 for holding the envelope against movement. An actuator causes engagement and disengagement of the rollers and clamping and unclamping of the clamp means and is movable between a transport position (rollers engaged and clamp means unclamped ) and an insert position (rollers disengaged clamp means clamped). As described, inserts are fed from tray (16, fig 2) via buckle chutes (24, 34) and rollers (20, 22, 32, 38, 50, 52) to drive roller 54 and inserted into envelopes held open by fingers 70 at the insert position. <IMAGE>

Title: TV receiver synchronisation circuit for line deflection - has control voltage path coupled to fixed DC voltage via switch, on failure of line sync. pulses, by generated switching voltage
Inventor: OHNEMUS FRITZ DIPL ING
IPC: H04N5/12
Filed: 1989-07-15
Abstract: The synchronising circuit has a phase control stage (4), fed from line synchronising pulses and an oscillator (6). There is a control voltage path with a low pass filter (5) between the phase control stage and the oscillator. The control voltage path is coupled to a fixed adjustable d.c. voltage (Ubc) via a switch (9). A switching voltage (11) is generated on failure of the line synchronising pulses (Z). The d.c. voltage actuates the control of the VCO to the rated line frequency. The switching voltage is pref. derived from a mute circuit, detecting the failure of the line synchronising pulses. The switching voltage may be applied to a base of a transistor, whose output circuit contains a resistance network (R1, P1, R2). ADVANTAGE - No frequency deviation of the line oscillator, on synchronising signal defect, without complicated circuitry.

Title: Continuous optic fibre drawing giving no stoppages of fresh material - uses preform chucks which change places to keep continuous feed to furnace
Inventor: LEPPERT HANS-DETLEF DIPL PHYS
IPC: C03B37/027
Filed: 1989-09-08
Abstract: To draw an optic fibre, the drawing action is continuous using an initial preform, within a nipper-type chuck, clamped in place, for the fibre to be drawn out. When the major portion of the preform has been drawn out in a fibre, a further preform is clamped in a nipper-type chuck and adjusted for alignment with the lower preform and steadily advanced towards it for them to be welded together by a precision burner. The lower chuck is opened and moved upwards, and the chuck still in position takes over the continuous advance of the preform into the furnace for fibre to be drawn out. The free chuck now in the upper position, takes a further preform (10) and repeats the process to give an uninterrupted fibre drawing  action. ADVANTAGE: The operation gives no stoppages on the introduction of fresh material.
