Title: Dry absorption of acid gases with lime using two=stage filter - with oxidn. of sulphur di:oxide by nitrous gas in first stage and absorption on fresh lime in second
Inventor: HOELTER HEINZ
IPC: B01D53/56
Filed: 1977-06-29
Abstract: Dry absorption of SO2, HCl, HF and NOx is carried out in plant with 2 consecutive textile stages. The first of these is charged with powdered lime to such an extent that oxidn. of SO2 to SO3 by NOx takes place mainly in the first stage and the already largely spent absorbent, e.g. lime, is retained in this stage until the loading is a few mg/m3. The reaction stage between the first and second filter stages is charged with fresh lime, of which the absorption capacity for harmful materials and chemisorption capacity of SO3 or SO2 and lime to CaSO4 or CaSO3 has not been impaired by precharged absorbent. The process avoids the regeneration of SO2 from the absorbent in the second stage. It is useful in the purificn. of waste gases from power stations, refuse incinerations etc.

Title: Non-destructive testing of sawn construction timber boards - uses measurement of forces required to achieve given degree of flexure
Inventor: CRZECZYNSKI TADEUSZ DR
IPC: G01N33/46
Filed: 1978-05-12
Abstract: The method and device are for non-destructive testing of sawn timber, esp. of boards for constructional applications. Elastic modulus measurement is enabled by determining the flexure caused by forces applied to surfaces of the boards and simultaneous board quality classification. The board is subjected separately to opposite forces applied at the same point until a defined deflection is achieved. The forces required to cause the standard detection are measured and the modulus of elasticity (E) calculated from a standard formula, typical E = 4PL3/fbh3 where P is the force in kg, L the length, f the deflection, b the breadth and h the thickness of the plank in cm. The values of P and f may be averages depending on the geometry.

Title: Machine gun breech block damping mechanism - has cylinder with buffer chamber at end for propellant gas
Inventor: SCHENK NORBERT
IPC: F41A3/90
Filed: 1978-05-19
Abstract: The damping mechanism is for the breech block of an automatic firearm such as a machine-gun, locked solidly into place and moving rearwards in opposition to a spring, which then thrusts it forward again. The block has locking members released in the sideways direction by a slide, and thrust inwards again by a release plunger on stopping a burst of fire. A gas passage leads into the end of a cylinder guiding the release plunger. The end (6) of the cylinder (4) has a buffer chamber (9) for propellant gas taped off from the gas passage, and it and the chamber have a single inlet (6') of set cross-section. When a sudden pressure rise (PV) occurs before the inlet, this cross-section is such that the ratio of pv to ph rapidly reaches unity, but when this pressure suddenly falls a reciprocal ratio maintains for a time (t) a predetermined value greater than unity, where ph is the pressure after the inlet, and t is longer than the time required for a forward and reverse stroke of the block.

Title: Plastic two=piece shell for capacitors - with thermosetting wafer inserted between capacitor body and lower shell-wall
Inventor: KOLLER GEORG ING GRAD
IPC: H01G4/224
Filed: 1978-10-14
Abstract: A capacitor has a casing consisting of two rectangular shells, with the capacitor connections leading out through the joint between the shells. After the capacitor body has been inserted into the first shell, a small amount of thermosetting insulating material is applied between the terminals to fill the space between capacitor body and inner shell wall. After the joint has been welded together, a heat treatment, combined with the drying of the lettering, cures the insulating material. This saves the long (12h) waiting time for the solidification of a 100% embedded capacitor before the next operations can begin.

Title: Three ball rotating pendulum display for clock - has spring-loaded spiked wheel driven by second shaft and providing torsion drive impulse to pendulum
Inventor: FEHRENBACHER WOLFGANG
IPC: G04C3/033
Filed: 1979-04-19
Abstract: The pendulum is hung by a torsion wire or tape from a fitting which is elastic on account of a spring permitting natural adjustment in the vertical direction. The pendulum is restrained from over-rotation by an attached projection stopped by striking a fixed pin. The three ball pendulum has a fixed natural frequency of about eleven seconds but is caused to oscillate at a frequency of ten seconds by means of an intermittent force applied by six spokes (25a) of a wheel (25) driven by the second shaft (27) of the clock. This wheel is driven via a coiled spring which ensures a smooth application of just sufficient torsion to turn the pendulum at this frequency.

Patent DE-2918480-A1 (DE)
Title: Acceleration regulator for fuel injection engine - compensates for build up of fuel pressure at inlet valves and assists mixture enrichment
Inventor: KNAPP HEINRICH DIPL PHYS DR
IPC: F02M69/26
Filed: 1979-05-08
Abstract: The fuel injection regulator steady state position is governed by a control fluid pressure line, the fluid (fuel) pressure being governed by a control orifice and an electrically-operated regulator valve. When the engine is accelerated the depression in the inlet manifold operates a sensor which alters the metered fuel inlet to the injector valves. The control pressure cannot, however, alter rapidly, thus there is an increase in fuel pressure behind the injectors, and the necessary mixture enrichment is delayed. By connecting a valve into a control fuel by-pass line upstream of the regulator valve and actuating this by-pass valve by the fuel pressure build up, the control pressure is transiently reduced and enabling correct fuel injection. The by-pass valve connects the control line to the fuel sump and thus puts a low impedance in place of the control valve.
