Title: Double drum winch for conveyor - has common brake with freewheel couplings to each drum acting on one paying out (OE150177)
Inventor: NESLER JOHANN
IPC: B66D1/26
Filed: 1976-05-19
Abstract: Double drum winch is for driving both runs of the haulage rope of a pendulum rope conveyor, the drums being pref. powered by a common source. A clutch is provided between the latter and each drum (T1, T2) preferably incorporating an epicyclic gear train (P1, P2). A common brake (B) serves both drums, being permanently coupled to them by freewheels (U1, U2). The freewheels operate in such a manner that the drum paying out the rope is always coupled to the brake. The freewheels can be mounted at the opposite ends of the drums to the clutches and flanged onto the drums. They have gears on their driven sides meshing with one on the brake.

Title: Coal gasification in situ - by electric induction heating through toroidal coils in coal seam section
Inventor: FISHER SYDNEY T
IPC: E21C37/18
Filed: 1976-08-13
Abstract: Coal by-prods. and energy can be produced from coal seams by inductive electric heating of a certain section of a coal seam in situ. This section is enclosed by the parts of the induction coil and the gaseous prods. are conveyed to the surface. When the seam has been converted to coke residue, a combustion agent is introduced and the gaseous extraction continues after the coils have been removed. This eliminates both the interference with the environment by open cast pits and the unsightly waste dumps, and the subsidences and dangers of underground mines.

Title: Umbrella with different protective cover widths - has adjustment mechanism on stock containing swivel-out rib shafts to increase surface cover
Inventor: KINSKI ERNST DIPL ING
IPC: A45B11/00
Filed: 1976-08-20
Abstract: The adjustment mechanism which can be used on umbrellas in order to expand the protective cover to protect two people basically comprises the opening member (25) which consists of two identical shells (25a, 25b) pref. stamped out of sheet metal.

Patent DE-2640463-A1 (DE)
Title: Precision shutter release for short, ,, hand-set exposures - delays opening shutter until moving release element has gained momentum
Inventor: NAKAGAWA TADASHI
IPC: G03B9/62
Filed: 1976-09-08
Abstract: The shutter release eliminates the effect of irregularities in the initial movement of the shutter-release element, esp. for the briefest exposures: for the longer exposures they are of less consequence. When a catch (2) moves aside, the shutter-release element (3) begins to turn clockwise. When it strikes a stop (34 against 83) the shutter starts to close. Meanwhile, its curved side has, at some point in its travel, contacted an adjustable stop (44) and set off the shutter opening (63). The shorter the exposure time, the later in its movement will the release element (3) stike the adjustable stop, and the more nearly will its momentum approximate to its final value: from whence stems the claimed precision.
Patent DE-2645011-A1 (DE)
Title: Partly transparent mirror for single lens reflex camera - has vapour-deposited metal and dielectric coatings
Inventor: WADA YOSHIHIRO
IPC: G02B27/14
Filed: 1976-10-06
Abstract: The mirror comprises a transparent baseplate e.g. of glass, a vapour-deposited metal layer and a vapour-deposited dielectric layer. The thickness of the dielectric layer is selected so that the reflection characteristics of the metal layer which changes with changing wave-length of the incident light (esp. high at the long-wave end is corrected by the reflection characteristics of the dielectric layer, and so that also the difference in transparency to the two polarisation components is reduced by the transparency characteristics of the metal layer. Discolouration of the image seeker picture of the falsification of the light intensity reading due to the polarisation components in the incident light are avoided.

Title: Ink supply bag for printer - has container with vent which closes automatically if bag breaks
Inventor: SICKING HEINRICH ING GRAD
IPC: B41J2/175
Filed: 1977-04-07
Abstract: The ink supply is esp. for an electronic printer and has an ink contg. flexible bag (4) arranged in a container (1).

Filed: 1978-08-19
Abstract: Prepn. of a salt of N-acetylglutamic acid (I) comprises neutralising (I) with a basic cpd. of a divalent metal, pref. Ca(OH)2. Pref. an aq. soln. is prepd., then the salt is pptd. by adding an organic solvent (pref. methanol, ethanol or acetone), recovered and dried at 105 degrees C.

Title: Automatic fire alarm system - uses measure of local velocity of sound as indication of temp. with triggering when threshold is exceeded
Inventor: MANTEL JUVAL DIPL ING DR ING
IPC: G08B17/06
Filed: 1978-08-23
Abstract: A fire alarm system provides an alarm triggering when a threshold value of temp. and rate of change of temp. is exceeded. A sine wave generated (2) provides an acoustic signal from a loudspeaker (3) that is transmitted across the room to a receiving microphone (5). A phase comparator (6) allows the transmission time to be measured and this is proportional to the local velocity of sound. The signal is subtracted (8) from a reference voltage (7) to operate a trigger (9) to produce a measure of actual temp. Both the temp. and rate of change of temp. (10) are compared with reference values (11, 12). When both are exceeded (13), the alarm is activated.

Title: Vibratory feeder for conveyors - has separately vibrated modular units coupled together to form one surface
Inventor: KESEBERG HEINZ
IPC: B07B1/34
Filed: 1978-11-10
Abstract: The vibratory feeder is used for conveyors and similar large surfaces. It consists of separate modular units coupled together to form a whole, each module being vibrated by its own unit and operating independently. For the separate modules to vibrate in wynchronism, a single control is used and the modules are coupled rigidly together. If it is required for each module to vibrate independently of the others, there is no coupling between them, the joints being freely covered; alternatively, the joints can be coupled through the use of flexible rubber mountings.
