Patent DE-3914303-A1 (DE)
Inventor: KUEHN HANS-ROBERT
IPC: G11B33/08
Filed: 1989-04-29
Abstract: This invention concerns a device with vibration-sensitive parts, e.g. a CD player, designed to be installed and operated in vehicles. Such devices require reading to be carried out faultlessly, even when the device is exposed to intense vibrations. The effective drive-gear mass generates, together with the elastic shock-absorber members, a relatively pronounced degree of resonance, corresponding to the shock-absorption which already exists, in the low-frequency region of the spectrum, in which the vibrations also lie. A particular disadvantage of prior art devices is that, owing to different installation conditions in various types of vehicle, as well as the different characteristics of different vehicles, and different conditions of use and operation of such devices, completely different vibration frequencies can lead to loss of read-out. The aim of the invention is to overcome these problems. This is done by using adjustable elastic shock-absorber members and damping them, thus enabling the resonant frequency to be changed in order that read-out quality remains unimpaired. The invention is applicable to vibration-sensitive devices such as vehicle-mounted CD players, plus for instance recording and play-back devices and DAT and DRAW equipment.

Title: Nozzle for spraying plaster or mortar - has mechanism for automatic shutting off of plaster or mortar when air supply is shut off
Inventor: REINHARDT HARRY
IPC: E04F21/12
Filed: 1989-05-19
Abstract: The nozzle (10) for spraying plaster, mortar etc. is connected by a flexible hose (11) to the pump which supplies the plaster or mortar. Compressed air is supplied through a flexible pipe (12) which is connected to an air nozzle (13) mounted inside the main nozzle (10). The air supply can be shut off by means of a tap (15) in the compressed air supply pipe (28). The closing of this tap causes a build up of pressure in the air supply pipe (28).  This pressure acts on a piston attached to a spring loaded shutter (18). This shutter (18) is pushed upwards into the nozzle (10) and shuts off the supply of plaster or mortar. USE/ADVANTAGE - Nozzle for spraying plaster and mortar.  Unused plaster or mortar is not left in the nozzle (10).

Title: Yarn laying - has deflection point to sever yarn between sleeve and take-off without a blade
Inventor: STITZ ALBERT DIPL ING
IPC: B65H65/00
Filed: 1990-09-28
Abstract: To lay a yarn at a constant speed on to a bobbin, clamped to a rotating spindle, the yarn is deflected between the yarn take-off and the sleeve at a point behind the sleeve, as seen from the take-off point of the take-off appts. The deflection point lies between the tangents from the take-off point towards the plane where the yarn is caught at the sleeve. After the yarn has been caught, the deflection guide moves at least 90 deg. round an incoming and emerging yarn level for a twist on a generally symmetrical axis. ADVANTAGE - The technique requires no blade for the yarns moving at high speeds, working with thick yarn material, to sever it between the bobbin sleeve and the take-off.
