Patent DE-2923081-A1 (DE)
Title: Height adjustable bottling and capping machine - has bottle lifting and lowering system operating in two lifting and single rapid lowering stages
Inventor: KEPPLER ULRICH
IPC: B67C3/24
Filed: 1979-06-07
Abstract: The system lifts the bottles, presses then against filling and capping mechanisms, and lowers them down after finished operation. For this purpose is used a bottle carrier operated by a pressure medium. Control pressure lift rapidly the carrier(s), when a counter pressure has been cut out and friction forces overcome. Then follows a slow stroke, using the required counter pressure, for pressing the carrier with the bottle against the filling and capping mechanisms. After finished operation the control pressure is cut out and the carrier lowered by counter pressure.

Title: Adjustable boring tool assembly - has two diametrically opposed cutting edges moving in or out simultaneously
Inventor: EPPINGER HEINRICH
IPC: B23B29/034
Filed: 1979-08-03
Abstract: A boring tool has two diametrically opposite cutting edges (17,18). Each cutting edge is mounted in a block which can slide in a transverse channel in the end face of the tool and can be clamped by screws (9,10). Each support block has a groove on its inner face to receive a pin (28,29) projecting from a disc which has a limited degree of rotation inside the body of the tool. When one of the blocks is moved radially, it rotates the disc which, in turn, drives the other block in the opposite direction so that each cutting edge is moved exactly the same distance.
Patent DE-2932279-A1 (DE)
Title: Small inaccessible pipe pushing rig - is controlled for alignment by laser beam and cutter head correction cylinders
Inventor: BERTHOLD ALFRED
IPC: E21B47/022
Filed: 1979-08-09
Abstract: Pipes pressed horizontally from a trench through an embankment are prevented from deviating from the desired direction by a laser beam. This is directed from the trench to a photocell array in the cutter head. Any deviation is signalled back to a control station so that hydraulic adjustment cylinders for the cutter head can be actuated. This is a secure means of ensuring a correct alignment where the pipes are too small for access by personnel. The concrete pipes are pressed through the soil from a trench by a steel tube to which a hydraulic cylinder is coupled by a clamp. A cutter breaks up the soil and a water spray removes the cuttings to a pit. The direction of the shoes of the cutter head is controlled by hydraulic cylinders. A laser beam is directed from the transmitter to a photocell array. Any deviation is signalled through a cable to a display unit so that the hydraulic cylinders can be actuated and can correct the deviation.

Title: Water dissolved gas collection - in expansion vessel near water level on top of riser
Inventor: MUELLER RUDOLF DIPL ING
IPC: B01D19/00
Filed: 1979-10-01
Abstract: Useful gas, specially methane, which has been accumulated at the bottom of stagnant waters by bacterial decomposition of organic sinks, is collected in an expansion vessel at the water level which is joined by a riser to the bottom layers. A pump returns the degassed water to the sea and the methane which has been released is kept at a certain pressure before it is admitted to a storage tank. Water contg. dissolved methane can be raised by this method at a high flow rate (6 m/sec at Lake Kivu in Zaite, where the methane content per litre of water is 0.32-0.48 litre).

Abstract: The choke coil framework (10) consists of two crosspieces (12,13) and two side pieces (14,15), the upper and lower crosspieces (12,13) having the connecting wires (16,17) protruding from their outer surfaces. These connecting wires (16,17) run along the inside of the coil frame (10) parallel to one another and bend outwards at each end, the lower ends of the wires long enough for insertion into a printed circuit board, and the upper ends for soldering the ends of the choke coil. A ferrite core (11), of double T-shaped cross-section is inserted into the framework (10), which has slightly inward curved ends (12,13), for clamping the core (11). The core itself is provided with a longitudinal groove (11c) on each surface which faces the connecting wires (16,17) to prevent contact between the two. The coil is then wound over the frame (10), and can be produced automatically, the form of construction producing excellent electrical and magnetic qualities. The component is eminently suitable for use on printed circuit boards.

The applied friction force is sufficiently great to cause take up of the play between the two drive gear pinions (2,3).
Patent DE-3016488-A1 (DE)
Title: Trigger switch for speed control of hand tool - requiring transiently higher pressure to move from low to higher speed operation
Inventor: STILTZ ERWIN DIPL ING
IPC: H01H13/50
Filed: 1980-04-29
Abstract: The application is typically to a hand held electric drill. The trigger switch (1,2) comprises an operating shaft (1') with a cut out section (8) ending in two sloping flanks (10,14). Attached to the shaft is the slider (5) of a potentiometer (4) with linear motion, and a return spring (7). The notched section (8) engages at the front end (10) with an on-off switch (11,13). In the notch runs a plunger (3) with a rounded end (3') which moves normal to the shaft axis against a spring (15) in a housing. Initial pressure on the trigger closes the on-off switch and sets the potentiometer to give the slowest speed. This speed can be gradually increased by a small value until the rear flank (14) engages with the plunger (3). To obtain a higher speed, considerable pressure must be applied to make the plunger rise up the flank. After that the pressure required for speed adjustment is again modest. The mechanism makes for easier control at very low speeds.

Title: Two=stage recovery of dil. ethylene and propylene - e.g. in fischer-tropsch residual gas, using initial solvent wash or fixed-bed sorption
Inventor: SCHRAMM WALTER
IPC: C07C7/00
Filed: 1980-10-29
Abstract: In a process for the recovery of small concns. of lower olefins from a gas stream, (i) they (and the corresp. paraffins) are concd. either by (a) washing out with a hydrocarbon and regeneration or (b) by cyclic fixed-bed sorption and regeneration; and (ii) the concentrate undergoes conventional low-temp. sepn. The original concns. are pref. at least 2 mole% each of ethylene and propylene, and the olefins concn. after (i) is at least 25 (pref. 35) mole%. Used esp. in treatment of Fischer-Tropsch residual gas. Olefins can be recovered economically from streams which are too dil. for use of (ii) alone. Costs are less than with the 2-stage process of US2915881, because the whole gas stream has there to be taken to low temp. and high pressure.
