Patent DE-2853945-A1 (DE)
Title: Safety or indicator fitting for instrument with thin walled panel - has housing with collar clamped around cylindrical section wedged to rim and in panel hole
Inventor: LEYEN GERHARD
IPC: H02B1/044
Filed: 1978-12-14
Abstract: An electrical component fitting e.g. an instrument safety fuse or an indicator lamp is easily attached to a thin-walled support panel. The latter is made with a hole which engages a cylindrically-shaped housing made of plastics. The front end of the housing has a flange overlapping the hole and a fixing bracket on the opposite side of the panel to prevent axial displacement. The housing is also protected against angular displacement. The housing (1) is fitted with a collar (10) which is wedged up against a projecting rim (3) of the cylinder at the remote end from the flange and just fits in the clearance hole in the panel. The collar is flexible and produces a tight fit in the hole. The housing is mounted by pressing to obtain a tight fit as a result of the spring effect. The cylindrical section of the housing (4) tapers from the flange towards the projecting rim.

Title: Multipurpose shredder for paper, microfilm, tape etc. - has drive in housing accepting cassette containing one or more cutting mechanisms
Inventor: JUNGHANS WOLFGANG
IPC: B26D1/24
Filed: 1979-02-16
Abstract: The shredder consists of a drive and several cutting mechanisms executing different cutting processes. Each cutter is mounted in an open chassis with no housing of its own. The chassis is located in the drive's housing. The cutting mechanisms are in the form of cassettes that plug into the drive's housing to perform the various cutting tasks. Each cassette may contain one or more cutting mechanisms. If it contains more than one, then the cassette is designed so that by simple movement inside the drive's housing the type of cutting mechanism can be changed over. Such movement can be simply sliding the cassette from one end of the housing to another.

Title: Synthesis gas generation by gasifying moist clarifying sludge - together with additional fuel whereby sludge components are oxidised odourlessly
Inventor: SCHUSTER LUDWIG DIPL CHEM DR
IPC: C02F11/10
Filed: 1979-03-12
Abstract: Synthesis gas is prepd. by gasifying still moist clarifying sludge, (A), with additional fuel (B), e.g. C dust, heavy heating oil and combustible waste. The generated gas can be used as heating- or synthesis gas. All substances in (A) are oxidised odourlessly.

Title: Forming coke fines for producer operation from caking coal - by adding Gp=VIIIB metals or cpds. before coking
Inventor: SCHMITT HUBERT DR
IPC: C10B57/06
Filed: 1979-04-09
Abstract: A process is described for the prepn. from coking coal of coke fines to be used in gas producers or sintering plants.

Patent DE-2921809-A1 (DE)
Title: Monitoring and testing of branch exchange from remote station - utilising branch controller to select required circuit in same manner as normal connections (NL 2.12.80)
Inventor: ELSTNER SIEGFRIED DIPL ING
IPC: H04Q1/26
Filed: 1979-05-29
Abstract: The incoming call can be received either at an extension of the branch exchange or, if so equipped, at the branch keyboard. When the outside exchange (FV) call has been identified at the branch exchange (A) as a test or supervisory call the person receiving the call initiates a call transfer in the normal manner but using a dedicated secure code number. The branch exchange automatic control then searches for a free code receiver (CE) and then makes an internal connection to couple it to the incoming call on the public line end (AS). The exchange system is then free to deal with other calls. After the connection the public telephone exchange controls the checking and data gathering routines, using the branch exchange automatic facilities as necessary.
