Patent DE-2802710-A1 (DE)
Inventor: SCHOLZ HORST
IPC: H02B1/01
Filed: 1978-01-23
Abstract: The framework arrangement consists of a plurality of framework rows having a specific number of individual frameworks arranged side by side. Each individual framework (1; 2) consists of two profiled metal sheets (14, 15; 16, 17) on the sides and upper and lower lateral struts (20; 21) which in each case connect said metal sheets. The individual frameworks (1, 2) rest on an adjustable height apparatus foot (3; 4) allocated to them and are fixed via lugs (5, 6; 7, 8) on fixed position retaining strips (9) which run along above the frameworks. These retaining strips also support a cable rack (11), which is arranged above the frameworks, for accommodating the framework wirings. As a result of this measure, there is no need for cost-intensive supporting profiles, which are an accident risk, underneath the framework arrangement in order to compensate for ground unevennesses. <IMAGE>

Title: Extracting hops with carbon di:oxide under specified conditions - to give low polyphenol extract used in brewing
Inventor: MUELLER ADAM DR
IPC: A23K20/111
Filed: 1978-07-04
Abstract: Extn of hops or hops prods is effected using CO2 followed by vapourisation of the CO2 from the extract obtd. For extracting resins, tar oils and low mol wt. polyphenols, a temp range up to the CO2 critical temp. and a pressure range above the CO2 critical pressure during all the extrn. are used. The extract is either further extracted to obtain oestrogenically active cpds, or isomerised by mixing with absorbents and liquid CO2 at high temp and pressure to form isohumulane. The initial extract is used in brewing beer. The oestrogenically active cpds, are used in animal feeds as protein synthesising agent, or in the prepn. of cosmetic prods or bath additives. The process enables an extract contg. all the better cpds, the low M. W. polyphenols, and the hops oil cpds, avoiding the extrn of high M W polyphenols and chlorophyll obtd in previous CO2 extrn processes.

Patent DE-2838637-A1 (DE)
Inventor: PLOMER JOSEF ING
IPC: E01F13/04
Filed: 1978-09-05
Abstract: The barrier device is made up of a series of crash barrier sections (1, 2, 3, 1'), of which at least one (1) can be displaced into the area of an adjacent crash barrier section (2). In the area where the two overlap, at least one roller (7) is arranged on the one crash barrier section (1) and at least one guide rail (10) is arranged on the other crash barrier section (2). Upon displacement of the one crash barrier section (1) the roller (7) runs along the guide rail (10). In this way it is possible using simple means to obtain an opening in the crash barrier device which approximates to the width of one crash barrier section (1, 2, 3, 1'). If the crash barrier section (2) adjacent to the displaceable crash barrier section (1) is connected to the adjacent positionally fixed crash barrier section (3) in a releasable manner, for example by bolts (17), the crash barrier sections (1, 2) pushed together can then move jointly and arbitrarily on runner wheels (13, 15). The result is double the width of the opening in the road barrier device.   The same procedure is in addition also possible in mirror image, a second displaceable crash barrier section (1') being displaced in the opposite direction into the area of an adjacent crash barrier section. In this way a further doubling of the opening width in the road barrier device can be obtained. <IMAGE>
