Title: Herbicidal 2-phenoxy propionic acid derivs. prodn. - from 2-chloro-propionic acid and corresp. phenol in presence of base, with azeotropic water removal
Inventor: KOCH MANFRED DR
IPC: C07C51/367
Filed: 1978-12-16
Abstract: Prodn. of propionic acid derivs. of formula (I) and their salts comprises reacting phenols (II) with excess 2-chloropropionic acid (III). In the formulae, W is H or alkali metal; Z = O or CH2; When Z = O, X = Cl, Br or CF3 and Y is H or Cl, and when Z = CH2, X = Cl and Y = H or Cl. Reaction is carried out in a water-immisicible solvent while distilling out water-introduced (or present) and simultaneously adding the calculated amt. (or a slight excess) of aq. alkali hydroxide. Alternatively, a mixt. of (II) and (III) (or its methyl ester) is heated under reduced pressure with the calculated amt. of alkali while distilling out water. (I) are herbicides, esp. for grasses and also precursors for other selective herbicides. Excess alkali is not present during reaction so hydrolysis of (III) to lactic acid is suppressed. Yields of (I) of 99.5-99.9% are achieved with a relatively small excess of (III).

The lower electrode roller pref. has a circular row of flat zones on its periphery, each zone providing an anvil during each welding operation. The recesses in the upper electrode pref. have a shape corresp. with the shape of the contacts. The electrode rollers can pref. be moved from their drive shafts. The heat generated in welding is easily removed via the electrode rollers.

Title: Continuous monitoring of crane load limiter computer and memory - using self comparison of memory contents test character and stopping operation when difference arises
Inventor: KOEGEL GERHARD DR ING
IPC: G06F11/00
Filed: 1979-03-14
Abstract: A monitor provides a real-time monitoring of the operational effectiveness of a computer and/or memory in a derrick-type crane load moment limited. In the event of a fault or power drop-out in the computer or memory a warning is given on the crane which is stopped, esp. from moving in a direction tending to increase the moment. For this purpose a continuous fault monitoring is performed during operation. In the absence of detected faults a test signal is formed continuously. When a fault is detected the signal is not generated, thus causing fault indication and/or the crane to be stopped. A test character is formed from the values of the entire memory contents and continually compared with the previously value at defined intervals. If there is a difference a fault is detected.
Patent DE-2912556-A1 (DE)
Title: Compressed gas driven motor - has liq. container from which gas evaporates and substance to heat gas fed to motor
Inventor: FARRER-HALLS JAMES ANTHONY
IPC: F02G1/02
Filed: 1979-03-29
Abstract: The gas driven motor has liquified gas in a reservoir (R) evaporated and expanded in a cylinder (2). A chamber (10) contains a substance which undergoes a change of state to release heat to the gas. The chamber feeds heat to the cylinder (2) through a tortuous passage (11) around an outer block (9) inside the housing (7). The arrangement prevents the evaporation cooling the gas and reducing the power delivered by the motor. In practice the temperature is increased at constant pressure or the pressure is reduced at constant temperature.

Title: Enlarging hole through concrete wall - involves pressing tapered units into holes made nearby, and blowing wall sections away
Inventor: NUMBERGER CHRISTIAN KONRAD
IPC: E04G23/08
Filed: 1979-07-04
Abstract: One or more holes (2) are drilled, close to the passageway, in a process for increasing the size of such a passage through a wall (1) made of concrete or other hard masonry material, or for breaking the wall away. The tapered end of a conical or wedge-shaped workpiece (3) is inserted in each hole.

Title: Thrust rod articulated joint - has plunger bore distorted inwards to secure ball head circlip
Inventor: THIEL RUDOLF
IPC: F16C11/06
Filed: 1979-08-24
Abstract: The articulated joint between a thrust rod and a thrust member, is particularly for use between the plunger and rod of a hydraulic brake booster, the rod having a ball head fitting in a bore in the plunger and held in place by a circlip. The wall of the bore near the mouth (10) of the latter is distorted inwards on the outside of the circlip (8), so as to secure this rigidly in place. The resilence of the material after the distortion operation gives the necessary axial clearance of the ball head (6) so that it can turn.

Title: Electric filtered coffee maker - has recirculation flow through water heater controlled by timer to prevent filtering at insufficient temp.
Inventor: LEUSCHNER UDO
IPC: A47J31/057
Filed: 1979-12-11
Abstract: The coffee maker has a through-flow water heater (14,16) supplying hot water to the filter vessel, with a return line allowing the water to be fed back from the water heater (14,16) to the fresh water side, for recirculation.

Title: Leaking gas return system to compressor - collects gas in exhaustion chamber and returns to suction side of compressor unit
Inventor: TIEKE OTTO DIPL ING
IPC: F16J15/00
Filed: 1980-01-16
Abstract: The system returns leaking gas from the stuffing box used to seal the piston rod of of a reciprocating compressor. The gas is collected in an exhaustion chamber sealed off from the surrounding atmosphere, and from which it is drawn off and returned to the suction side of the compressor. A pressure of 200 to 500 Pa above atmospheric is maintained in the chamber. There can be an exhaustion chamber before the main stuffing box, sealed off from the atmosphere by a preliminary stuffing box and connected via a pipe to the suction side of an ejector. A further pipe from the pressure side of the compressor leads to the ejector pressure side, and contains a control valve whose control pipe leads to the chamber.

Title: Plastics blow-mouldings successively transferred to turntable - with several seatings to permit blow-mouldings to cool during travel to subsequent treatment stations
Inventor: FROHN WALTER DR ING
IPC: B29C49/42
Filed: 1980-01-22
Abstract: A machine for the prodn. of plastics blowmouldings, e.g. bottles, comprises a transfer device which receives a parison at an upper level, esp. from an extruder head, and delivers it to a vertically divided two-part blow mould at a lower position in a blow mould support. In the lower position a blowing mandrel blows the parison to produce the blowmoulding. The blowing mandrel, carrying the completed blow moulding, is then transferred on a slide from the blow mould closure unit horizontally in the direction of the blow mould dividing plane to a position tangential to a turntable comprising a number of seatings, the seating at the tangent point receives the blow moulding from the mandrel, and, as the turntable revolves cyclically in step with the blow moulding prodn. process, advances the complete blow mouldings at least to one subsequent treatment station. The blow moulding closure unit has horizontal guides for the blow mould support located only at the side remote from the mandrel slide. For the rapid prodn. of plastics blow mouldings, such as bottles, from esp. extruded parisons. By transferring each blow moulding while still hot and plastic onto a receiving turntable possessing a number of seatings for such blow mouldings, it is possible to remove the blow mouldings successively from the machine at the rate at which they are produced, without requiring waiting time for the blow mouldings to cool sufficiently for flash to be removed and other operations to be completed on them. By arranging the slides on the side remote from the mandrel slide unobstructed access for removal of the mandrel with blow moulding is provided.
