Patent DE-3906627-A1 (DE)
Title: Method and arrangement for area monitoring (room monitoring) using the pulse-echo method
Inventor: KOLB HANS
IPC: G01S15/52
Filed: 1989-03-02
Abstract: Monitoring is carried out to determine whether people have entered a room in an unauthorised manner. Ultrasound pulses are radiated into the room. The signals reflected in the undisturbed room are recorded, digitised, and stored as a reference profile. These echo signals change in the event of defects and when people are in the room. Typical defects can be defined and described by algorithms. According to the invention, the echo signals are assessed using these algorithms, to determine whether a defect is present or somebody has penetrated into the room. In the second case, an alarm is triggered. The advantage provided by this is high sensitivity in the detection of the penetration of people into the room while at the same time precluding other alarms caused by defects (disturbances).

Patent DE-3927122-A1 (DE)
Inventor: NEUEDER LUDWIG DIPL ING
IPC: B29C45/17
Filed: 1989-08-17
Abstract: In the case of an injection moulding method for making hollow plastic objects, in which a fluid is forced into the mould under pressure immediately after injecting the plastic polymer melt, so that the polymer melt spreads out over the surface of the mould cavity, the fluid is forced into the mould cavity through an injection sleeve, which is in the inner sprue region of the moulding and is surrounded by flowing plastic polymer melt, so that the forced-in fluid reaches the mould cavity without first coming into contact with the plastic polymer melt. The apparatus for making such plastic objects has an injection sleeve, provided at a distance in the inner sprue region of the moulding, for the fluid feed into the plastic polymer melt injected into the mould cavity, which sleeve controls the direction of the flowing-out fluid in such a way that it coincides with the direction of melt thrust in the mould cavity. <IMAGE>
Patent DE-3929265-A1 (DE)
Inventor: BUBIK ALFRED DR
IPC: D21F9/00
Filed: 1989-09-02
Abstract: The ledge is arranged transverse to the machine direction in a substantially flexure resistant manner and is adjustable for guiding the wires between which a web of material is formed. The ledge contains a guide surface which faces the wires and has a special contour. For improved control of the pressure changes occurring in the region of the ledge, the ledge contains a supporting member and a pressing member which contains the guide surface. A pressing device is supported at the supporting member and the pressing member can be adjusted in a direction relative to the wires as well as relative to the supporting member by using the pressing device for simultaneously elevating the pressing member and inclining the pressing member with respect to the machine direction. Advantageously the pressing device constitutes a hose which is subjected to a pressurizing medium and thereby deformable. The hose is at least partially imbedded into the supporting member such that its deformation causes movement of the pressing member. For simultaneously inclining the pressing member during such movement, a connecting member is provided between the pressing member and the supporting member. The ledge permits the adjustment of optimum pressures along a sheet forming zone whereby the sheet formation is improved.

Title: Tool for opening window with inaccessible handle - consists of long bar with pivoting lever attached to one end
Inventor: MONSTADT ULRICH
IPC: E05F9/00
Filed: 1989-12-01
Abstract: A window which is opened or closed by a handle which is difficult to reach, can be opened or closed by means of a long bar (8) which has a lever (9) pivoted to its outer end.  This lever (9) carries a tubular socket (10) which can be pushed over the handle. An oblique joint face (11) prevents the lever (9) from rotating when the bar (8) is swung in an anti-clockwise direction so the window handle rotates with the bar (8). Swinging the bar (8) in a clockwise direction enables the lever (9) to rotate through 90 deg. when it abuts against the stop (12). USE - Opening windows with handles in inaccessible positions.

The hollow body is forced, under pressure, against the surface of a mould to distort it into the required shape for the groove. The hollow body is a tube, pref. of a suitable glass material. A heating zone is in front of the shaping zone, followed by a press zone. The hollow body is advanced in steps through the assembly. The mould is a hollow body, with the shaped groove at its inner surface. The hollow body for the mould is in two parts. The pressure is applied by blowing through the glass tube to force its wall against the shaped section of the required groove type. ADVANTAGE - The optic fibre guide groove is accurately shaped without a repetition of the effort required in its formation as the mould is only made once and can be used repeatedly.
