Patent DE-3921943-A1 (DE)
Inventor: SCHROEDER GUENTER
IPC: H04M1/2749
Filed: 1989-07-04
Abstract: 2.1. Modern office communication systems, although capable of easing the workload for the user, require special knowledge and much experience to be operated. 
<??>The network connections of the office communication systems provide for information interchange, particularly the paperless transportation of messages, information items and documents having the same and/or different word processing systems, filing systems, processors and so forth via different communication networks for switched connections. 
<??>2.2. To provide for the transmission of stored messages, for example data, image information items and so forth to any device and at any time and to reduce the communication process largely to functions at input commands which are known to the user, an automatic dialling device is provided in the office communication system which is connected to a user-settable time switching device with calendar function and with a control device. The automatic dialling device establishes a connection via the communication network in accordance with the data entered by the user and a remote data transmission of the messages and/or image information items stored in the mass storage device occurs via communication interface devices under control by the control device. 
<??>2.3. The office communication system according to the invention can be used in differently configured communication networks for switched connections and provides for the automatic transmission of any message and/or image information items at an inexpensive time.

Title: Repairing damage in rubber articles - by hot pressing cleaned affected area between natural rubber repair patch
Inventor: HELFENBEIN KLAUS
IPC: B29C73/10
Filed: 1989-08-14
Abstract: Articles of rubber such as conveyor belts, tyres etc. are repaired by placing a repair patch on the affected part, heating, and pressing it down. The patch has also a bonding film of sulphur-free or accelerated natural rubber or, alternatively, an adhesive film. Such a film is pref. polychloro-prene, neoprene or similar contg. a hardener. A damaged area on a rubber tyre is first roughened to remove dust and dirt, and a (e.g.) natural rubber patch is laid on, assuming the tyre is cold cured or is a hot cured conveyor belt instead. If it is a belt requiring cold bonding then an adhesive film is used.  Suitable plates are placed above and beneath the area which is hot pressed together with the top repair patch. During the hot pressing stage sulphur in the article and repair path reacts with the intermediate layer which itself is sulphur-free. If the bonding patch is free from any accelerator its own sulphur reacts with accelerator in the article and repair path. ADVANTAGE - The process is free from environmentally or hygienically undesirable effects and it saves time.
Patent DE-3928078-A1 (DE)
Title: Thermostatic defrost limiter switching evaporator fan - utilises both contact movements of thermostat with hysteresis for joint control of fan and heater relays
Inventor: SINGER WERNER
IPC: F25D21/00
Filed: 1989-08-25
Abstract: The defrosting is timed by a clock operating a first contact (4,5) to switch the heating on and off. While the heater relay is energised it holds off the fan relay by a second contact (21,22). At about 10 deg.C the thermostat operates while the compressor continues to run, and water remaining in the evaporator freezes. At a second thermostat setting the fan is started. USE/ADVANTAGE - In stationary refrigerators defrosted by electricity or hot gas. Costs of one thermostat and three terminals avoided, with savings on cable, fixing material and assembly time.

Title: Pocketing slide frames into sleeves - involves accelerating device and waiting positions allowing insertion of groups of frames
Inventor: LOERSCH JOHANNES
IPC: B65B35/40
Filed: 1989-09-28
Abstract: To place slide frames in pockets in a cover sleeve each supplied slide frame (6, 7, 8) is moved in an accelerated movement into a waiting position. When a certain number has reached the waiting position, this group is lifted up from the waiting position in the time saved by the previous acceleration relative to the continuous approach movement. The cover sleeve (19) for the group of frames in the waiting position is supplied rhythmically from below across the incoming supply direction whereby the openings of the pockets (25, 26, 27) are directed back and face the front edges of the frames lying across the incoming supply direction. The sleeve cover is turned 90 deg. so that the pockets lie in the direction of the frames in the waiting position. The pockets are opened by the incoming frames which are then inserted fully and the cover sleeve is advanced by a further row of pockets. USE/ADVANTAGE - High speed automatic pocketing system for slide transparency frames.

Title: Constant pressure system for oil mfr. - with two plates having orifices and rotating relative to each other to vary orifice size
Inventor: NEUPERT FRANK
IPC: B30B11/24
Filed: 1990-11-05
Abstract: A granulating head maintains constant internal pressure in a continuously operating, expanding, extruding and screw press used for initial processing of extracted material prior to oil mfr.
