Title: Telephone exchange line testing circuit - gives details of lines to be tested and tests to group control which forms test connections as for normal traffic
Inventor: SEEGER HELMUT
IPC: H04M3/32
Filed: 1977-06-20
Abstract: The telephone exchange trunk line testing circuit includes a central control (ZST) which gives particulars of the line (Ltg) to be tested and the nature of the tests to be made to a group control (SGO). a scanner in the group control (SGO) then determines whether the line is free. If so, the group control then establishes, via the line and the terminal devices (LE1, LE2) connected to it and via an inpu selector (EW) and a search selector (SW), a connection to an automatic testing device (AP). Thereupon signals by which all the functions of the line and the terminal devices are tested are exchanged between the group control (SGO) and the automatic testing device (AP). The testing device (AP) sends "good" or "bad" reports to the group control (SGO), which passes them on to the central control (ZST).

Title: Fibre reinforced metal composite material - produced from microscopic fibres by mixing, cold pressing and liquid phase sintering
Inventor: DIVECHA AMARNATH P
IPC: C22C47/14
Filed: 1977-10-12
Abstract: The composite material is produced by obtaining a uniform dispersion of ceramic fibres in metal powder by dry mixing, followed by cold pressing, heating the compact to produced further densification, and finally hot pressing, to obtain still further densification. Pref. the fibres have a dia. of 10 u and the fibre-powder mixture is extruded >=3 times to provide a uniform dispersion.

Title: Microprocessor controlled vehicle system - is monitored using control pulse whose first absence causes restart and second emergency action
Inventor: SCHWAB MANFRED DIPL PHYS DR
IPC: G05B19/04
Filed: 1978-09-29
Abstract: A monitoring device for program controlled devices, esp. microprocessor controlled vehicle systems, involves detecting a control pulse during each program cycle. It differentiates between faults arising during a program cycle, deciding whether they result from temporary faults or system failure. This enables use of a reliable criterion for operating an emergency switch. If no control pulse is detectd a new program cycle is initiated. A time element drives a coincidence circuit connected to the device so taht the coincidence circuit is switched when no further pulse is detected during the timer rest period.

Title: Optional direction signal connection to guide post - involves connectors on separate elements form locking for mounting either way
Inventor: WEICHENRIEDER ERICH
IPC: E01F9/619
Filed: 1978-10-23
Abstract: The guiding post at a roadside has a directional sign, such as one indicating the position of an emergency telephone, in one setting selected from two. The sign (12) is a structural element which is separate from the post (10). The post and sign have connecting elements, working together with a from-locking action. Those on the post are arranged so that those (26) on the sign can be brought into engagement with some of them in either of the two settings. This can involve spreader dowels on the sign and holes in the post. This means that position need not be determined until the post is set up. Polyethylene is a suitable material for the constructing the post.

This permits use of roof space as bedroom, with full standing height for adults where beds are sited.
Patent DE-2904242-A1 (DE)
Inventor: SCHENCK GUENTHER O PROF DR
IPC: A61L2/10
Filed: 1979-02-05
Abstract: Various embodiments of photoreactors are disclosed which have at least two irradiation chambers with a window therebetween. Ultraviolet radiation is introduced into one of the chambers at a side opposite the window so that it passes through that chamber, through the window and into the other chamber. The fluid medium to be purified is passed through the chambers and subjected to the radiation while in the chambers. The flow of the medium is through the chambers in series. The chambers are optimized in depth with respect to efficiency in terms of the flow-dose rate. In a two chamber photoreactor traversed by parallel radiation the maximum is at a total absorption of about 70 percent and at an absorption of about 27 percent in the chamber immediately adjacent to the radiation source. In an annular two chamber photoreactor with an elongate radiation source extending along the axis thereof the corresponding data are 45 to 65 percent and 16 to 25 percent, respectively. In an immersion type three chamber photoreactor of analogous configuration the corresponding data are 60 to 80 percent and 14 to 20 percent, respectively.
