Patent DE-3428713-A1 (DE)
Title: Method and device relating to a closed ice accummulator for the supply of cold to a room air-conditioning system
Inventor: HILBERS HEINRICH ING GRAD
IPC: F25D3/00
Filed: 1984-05-26
Abstract: The invention relates to a device which is used to store the required work of refrigeration for operating an air-conditioning system during the time when power is cheap such as, for example, during the night. The water in the refrigeration circuit is largely converted into ice in a tube bundle exchange vessel, where it is stored, by a cold-producing machine designed with a lower output. Because of the physical property of concentrating energy by the transformation of water into ice, it is possible to accummulate a relatively large quantity of refrigeration energy in a small storage space. Said energy is returned during the time of consumption on the following day by melting the ice to form water, and in this process the load dependence of a refrigeration requirement in air-conditioning technology is transferred purely onto the simple melting of ice, while the cold-producing machine experiences no special stress due to differing load reduction. This results in savings in energy and in the simplified embodiment of the refrigeration plant.

Patent DE-3438738-A1 (DE)
Title: Device for releasably attaching a lining to a wall
Inventor: GMEINER GUENTER DIPL ING
IPC: F16B19/10
Filed: 1984-10-23
Abstract: For the purpose of releasably attaching a lining to a wall an attachment part fixed captively to the lining is proposed, whose swivelling part supported against the outside of the lining holds a feeler which is in operative connection with two cams integrally formed on the lining.

The expanding ring is secured by means of a head part latched onto the end of the pin and following an associated hole in the wall, grasping behind the latter in a securing manner, expands when the swivelling part, rising from the front side of the lining on the cams, runs up into a locking position.
Patent DE-3443980-A1 (DE)
Title: Circuit arrangement for feeding in the AC ringing current, preferably derived from the alternating mains voltage, to the subscriber line of a digital telephone system
Inventor: KOPETZKY HORST DIPL ING
IPC: H04M19/04
Filed: 1984-12-01
Abstract: In a known circuit arrangement, the AC ringing currents are fed in via the normally-open contact of a ringing relay and flow through the power resistors of the power circuit. This results in unwanted power dissipation. To prevent the alarm indication circuit for the indication of the line states from responding to AC ringing currents, circuit measures have been taken in the known case which, however, undesirably increase the response time of the alarm indication circuit. For feeding in the AC ringing currents, a change-over switch (U) is therefore used by means of which the ringing voltage source is applied to the subscriber line in the ringing phase but the power resistor (R1) is disconnected from the line. This special arrangement of the change-over switch and the use of a varistor (V1) prevents an inadmissibly high current from flowing via the contact of the change-over switch in the event of bouncing. <IMAGE>

Inventor: ROEDER ERWIN PROF DR ING
IPC: B29D99/00
Filed: 1985-05-10
Abstract: The tendency of modern industrial systems towards higher and higher service temperatures, lower density and good mechanical properties and the simultaneous requirement for low material costs requires the use of glasses, glass-ceramics and ceramics as the matrix material in fibre-reinforced composite elements and thus the development of novel production processes for the continuous or quasi-continuous production of corresponding semifinished products. The only process known hitherto for the production of mouldings from glasses and glass-ceramics which are reinforced by means of continuous fibres is hot pressing, a batch process for the production of mouldings of limited dimensions. In the invention presented here, as can be seen from the above invention title, fibre-reinforced semifinished products are produced by first pre-compacting a fibre bundle impregnated with glass powder which is fed into a machine element in the form of a drawing die by means of the novel device necessary for carrying out the process, and then, in a pressing chamber, by the therein ...
