Patent DE-2405009-A1 (DE)
Title: Fastener for connecting panels edge to edge - is operable from side of panel assembly with undercut recesses
Inventor: HELDEN WILHELM VAN
IPC: F16B5/00
Filed: 1974-02-02
Abstract: The panels have undercut recesses along their adjacent edges. The fitting comprises two parts engaging the respective recesses, and a bolt extending through the two parts has lateral extensions to engage the mutually remote sides of the parts. One of the extensions is a pine engaging a snail cam at the adjacent face of the one part so that when the bolt is turned the parts and thus the panels are drawn together into edge to edge abutment. The bolt is turned by means of a flat tool inserted from one side of the panels into position there between.
Patent DE-2406288-A1 (DE)
Title: Bland textured soy protein prodn - by fermenting moistened vegetable par-ticles and adding steam under pressure
Inventor: VALENTAS KENNETH JOHN
IPC: A23L11/30
Filed: 1974-02-09
Abstract: Vegetable protein particles having a moisture content of 30% are fermented pref. by the addition of yeast. Following fermentation they are treated in a pressure vessel into which steam is introduced. The treated particles are discharged through a narrow orifice at one end of the pressure vessel to become texturized. The methoed is suitable to texturized soy bean, peanut, cottonseed, safflower and sesame seed flour. The fermentation process modifies the oligosaccharides into simple sugars which are in turn converted to alcohol and carbon dioxide. During the pressure treatment the alcohol and CO2 are removed. The process removes the characteristic "sweet" or "beany" flavour of the vegetable protein material. The fermentation takes place with low moisture content thus avoiding the need to dry the slurry associated with previous methods where fermentation took place with excess of water.

Patent DE-2451277-A1 (DE)
Title: Circuit for DC powered locomotive - includes one or several drive motors
Inventor: GARCON HANS
IPC: H02P3/08
Filed: 1974-10-29
Abstract: In the case of resistances used to reduce the field, the circuit includes additional switches (a7/a8) to control a run with an excitation of 30% of the normal value. These switches necessitate a somewhat greater capacity for the shunting switches (a4/a5). In fast switching from braking to the zero position with a high-speed train, the shunted field windings (F1/F2) have their switches placed in the off-position and then the circuit of are armatures (A1/A2) is broken. As a result, the time constant of the field winding is decreased and the switching is made with little current.

Title: Control of number of applications of paraffin-peloid packing - by adding methyl salicylate, peppermint oil, and cyclopenta-decanolite
Inventor: BERGER RAIMUND DR
IPC: A61K35/02
Filed: 1974-12-23
Abstract: A paraffin-peloid-packing prepd. is by the addn. of 3g methyl salicylate, 3g peppermint oil and 1g cyclopentadecanolite to 1 Kg paraffin-peloid. Paraffin peloid packing can be used many times on different patients but its use has been restricted to about 30 applications. The control of the number of repeated applications can be difficult. The invention overcomes this problem by adding an odorous substance to the paraffin-peloid packing which disappears or is greatly weakened after 30 applications of the packing.
