Title: Traversing cutter for face=to=face woven pile fabrics - has dual circular blades rotatable in opposite directions
Inventor: HEESEN HANS NORBERT
IPC: D03D39/18
Filed: 1980-03-11
Abstract: Cutting device for separating face-to-face woven pile fabrics in the loom has a pair of circular blades mounted on a traversing carriage which can be rotated by an intermediate pinion in frictional contact with the rail on which the carriage runs. The blades rotate in opposite directions, dependent upon the direction of motion of the carriage, and shortly before the end of one traverse of the carriage, a reversing mechanism disengages the pinion of one blade from the rail, and engages the pinion driving the second blade when the carriage commences its return journey. This arrangement is more convenient than a single blade, which has to be arrested, and its motion reversed, when the carriage reverses direction. The blades are less subject than is a single blade to undesirable vibration, have a longer life, and give a cleaner cut.
Patent DE-3021654-A1 (DE)
Title: Planar push=pull signal mixer - has earthing surface of microstrip line forming overlapping regions with slit of skid-fin line of opposite substrate side
Inventor: HAUTH WOLFGANG DIPL ING
IPC: H03D9/06
Filed: 1980-06-10
Abstract: The oscillator signal is supplied via a microstrip line and the h.f. signal via a slit, or skid-fin line to two mixing diodes. The i.f. signal is coupled via a shunt circuit from the microstrip line. The latter and the slit line lie at the same substrate side and contact the mixing diodes via their conducting surfaces. The earthing surface of the microstrip line forms overlapping sections with the conductive surfaces of the slit line on the opposite side of the substrate. The overlapping sections are so arranged and dimensioned that the impedance for the oscillator frequency in direct vicinity of the diode contacts of the slit line side is negligible between the conductive surfaces and a earthing surface. The latter for the microstrip line has a slotted recess of quarter wave length for the oscillator frequency, starting at the end of the slit line and extending in the direction of the microstrip line.

Title: Steam circuit for prime mover - provides expansion from superheated into saturated phase, with condensation completed at constant temp. and pressure using compressor
IPC: F01K19/02
Filed: 1980-08-01
Abstract: The steam driven prime mover conventionally uses a liquid medium raised to the superheated state by external heat. It may be either a continuous-flow or a piston engine. The expansion process involves a constant-pressure, followed by an adiabatic stage which continues into the saturated phase. The saturated vapour is completely condensed, whilst remaining at expansion end-point temp. and pressure, using either a continuous-flow or a piston compressor. It is then raised to the steam working-pressure by a feed pump and returned to the steam generator.
Patent DE-3029394-A1 (DE)
Title: Nuclear power plant double cut=off valve for steam or air - has second valve unaffected by pressure surges which could trigger unintentional opening
Inventor: SCHABERT HANS-PETER DIPL ING
IPC: F01D17/14
Filed: 1980-08-01
Abstract: A shut-off valve assembly for compressed steam, air or gas comprises two main valves (16,17) connected in series; each main valve is preceded by a magnetically actuated precontrol valve (33); this control valve controls the loading of a piston (28), connected to the valve plate (25) of the main valve, by a gas in such a way as to hold the main valve plate closed by the medium and, when the piston is relieved of gas pressure, to move it into the open position. The second main valve (17) in the flow direction has a precontrol valve (33) with a 3-way function; in addition to relieving the piston (28) it also controls its loading with gas pressure in such a way that, when the precontrol valve (33) is in the position where pressure relief is blocked, there is a larger flow cross-section (35) acting upon the piston (28) than in the pressure relieving position. The effect of the 3 way precontrol valve is that pressure changes act with very little delay upon both sides of the piston (28), with the result that the piston is actuated only intentionally, and the opening of the second main valves does not take place or is limited to only a few milliseconds.

Patent DE-3116992-A1 (DE)
Title: Central heating boiler
Inventor: KLOSE EGON
IPC: F24H1/28
Filed: 1981-04-29
Abstract: A central heating boiler for forced-draught burners is to be designed in such a manner that no condensate collects in the region of the boiler walls even in the case of boiler water temperatures below the dew point. To this end, the boiler consists of water-bearing parts, e.g. of boiler sections (1) with annular elements (2, 3, 12) which form a standing cylindrical furnace body (6) and an annular cylindrical heating gas flue (7). A furnace body muffle (10) deflects the flame coming from an upper forced-downdraught burner (9) and serves at the same time to divide the boiler into an upper combustion space region and a lower downstream block (11). Condensate arising drips from the boiler walls onto a slightly inclined lower limit (17) of the heating gas flue (7) and from there through a small flow opening (18) into a lower condensate collector (16) which at the same time absorbs condensate from the waste gas duct (14) through a flow opening (15). <IMAGE>

Title: Delivery plunger drive of a dough-portioning device
Inventor: SCHROEDER REINHARD
IPC: A21B5/04
Filed: 1981-05-19
Abstract: A delivery plunger drive for a dough-portioning device can be provided, in the case of which an elongated preliminary chamber (6) is provided which can be closed off at the top by means of a sliding blade (7), past the delivery end of which preliminary chamber (6) measuring chambers (2) can be moved in a dough-cutting manner and in which preliminary chamber (6) a delivery plunger (26) can be moved in a reciprocating manner by a rotating drive shaft (8) via a crank mechanism (14, 15... 24, 25), into which an adjustable power limiter, which acts by means of a spring (22), is interposed. It is desirable for the power limiter to make it possible to process the dough in a more uniform manner during filling of the measuring chambers (2) and for the dough to be cut off more gently once the measuring chambers have been filled. This is achieved if the power limiter takes the form of a rotary friction clutch (17) which is loaded by the spring (22), slides through in the event of predetermined braking of the forward stroke of the delivery plunger (26), on the one hand, and on the other hand, slides through towards the end of the return stroke of the delivery plunger (26) owing to the coming to rest of a stop part (27), which is connected to the crank mechanism (25, 24, 19, 16, 15, 14), against a stationary stop (28). In the case of this delivery plunger drive, the pressure exerted by the delivery plunger (26) on the dough is limited, constant and independent of how much dough is situated in the preliminary chamber (6) upstream of the delivery plunger. The pressure exerted on the dough during cutting is not increased, but simply corresponds to the sliding friction of the rotary friction clutch (17). Re-pressing by the delivery plunger during cutting is prevented in particular. <IMAGE>
