Abstract: There is described a new process for the preparation of optically active 2-(2',2'-dihalogenovinyl)-cyclopropane-1-carboxylic acids substituted in the 3 position, and derivatives thereof. A racemate of certain cyclobutanones is reacted with a sulfurous acid salt of an optically active base to obtain a mixture of diastereomeric 4-(2',2',2'-trihalogenoethyl)-cyclobutane-2-sulfonic acid salts; this mixture is then separated into the pure diastereomeric sulfonic acid salts. Either the pure diastereomeric sulfonic acid salts are converted directly to the desired optically active products, or the optically active cyclobutanones obtained from the pure diastereomeric sulfonic acids salts by decomposition are converted, in the presence of a base, to the desired product. Optionally, the product, optically active 2-(2',2'-dihalogenovinyl)-cyclopropane-2-carboxylic acids can be converted to their 1',2'-dibromo derivatives.

Abstract: In a plough of the kind which comprises a mobile frame (1, 2) and at least one plough member (15A) that will wholly or partly invert a furrow slice when the plough is in operation, said furrow slice is cut loose by a V-shaped blade (18) located at the front of the frame (1, 2) with respect to the intended direction of operative travel (A) of the plough and is both compressed, and deflected laterally towards one side wall (2) of the frame (1, 2) by a plurality of rotary lateral displacing members (4, 5, 6, 7, 8) that are in the form of rollers arranged in a row that is inclined to said direction of travel (A), the members/rollers (4, 5, 6, 7, 8) being of progressively increasing size considered rearwardly of the direction of travel (A). The lateral displacing members/rollers (4, 5, 6, 7, 8) co-operate with a soil guide member (15) at the rear of the plough in turning the cut furrow slice about an axis which extends in the direction of operative travel (A) to enable said furrow slice to be deposited substantially completely back into the furrow from which it was originally cut in a substantially completely inverted condition as compared with its original position. In a modification, the number of lateral displacing members/rollers is reduced and the guide member (15) in the form of a fixed plate is replaced by a power-driven rotary soil guide member of annular formation, the inverted furrow slice being delivered back into the furrow from which it was cut through the interior of said annular guide member.

Abstract: The invention relates to a method for manufacturing a veneer web composed of individual veneer strips of finite length and width which are pre-cut from a peeled veneer sheet. According to a known method, the strips are cut from the veneer sheet in random sizes, depending on the presence of faults or quality variations of the veneer sheet, whereupon they are combined in a tesselated pattern. An object of the invention is the provision of a method permitting veneer webs of practically any desired width and length to be produced in an economical manner with optimum utilization of the faultless and acceptable-quality portions of the peeled starting veneer material. To attain this object, the invention provides that the peeled veneer is cut to strips of equal width, that the absolutely non-usable strips are discarded, that the usable longitudinal sections of partially usable strips are trimmed of such strips, that the fault-free strips and the fault-free strip sections are joined to form continuous ribbons, and finally that these ribbons are joined transversely of their longitudinal direction to form a veneer web of a desired length and width.

Abstract: A fuel injection arrangement for air-compressing, spontaneous-ignition, internal combustion engines. The arrangement includes at least one electromagnetic control valve via which a high-pressure channel of a fuel injection pump can be connected with a low-pressure channel. The control valve includes a valve body which is in the form of a piston valve, is spring-loaded, and is axially movable in a housing chamber which is provided with at least one connection on the high-pressure end, and with a connection on the low-pressure end. The piston valve is in operative connection with an electromagnetic adjusting device which can preferably be controlled by an electrically-operating data processor. The piston valve region on the high-pressure end is delimited by a valve seat and has a fixed diameter which corresponds to the diameter of the valve seat. The piston valve region on the low-pressure end has a diameter which is less than that of the piston valve region on the high-pressure end. The housing chamber taken in its entirety is sealed off in such a way as to be resistant to high pressure. The chambers on the low and high pressure ends can be connected by at least one line. The inventive fuel injection arrangement is characterized by an extremely stable behavior of the control valve and an absolute sealing in the closure position of the piston valve, so that the fuel injection arrangement itself is operational at the highest injection pressures.

Abstract: Coin-operated formation, cooking, and delivery of individual portions of rehydrated potato food product. Prior art devices employed raw potato pieces to form the individual portions, requiring special storage arrangements to prevent deterioration of the stored product and relatively extended cooking periods. The present invention overcomes these deficiencies by employing dehydrated food product which is easily stored, rehydrated, formed, shaped, and may be cooked in a greatly reduced time period. The apparatus includes a mechanism (22, 68, 180) for delivering an amount of dehydrated food product corresponding to the size of an individual order, a chamber (60) and system (80) for rehydrating the product, a mechanism (130, 138) for cutting rehydrated product forced (124) out of the chamber, a cooking device (26) for the severed product, and a conveyor (28) for delivering cooked product. The invention further provides a lever (80) that combines a closure for a carrier (68) of dehydrated product with a shower head (82) for furnishing water for reconstituting the product, and provides a device (140) for cooking and for conveying rehydrated product.

Abstract: For the purpose of averting overloads in a telephone exchange system which comprises information-processing sequential logic systems and overload averting circuits, seizures are counted by the counter according to their respective significance or weighting. Different weightings are stored in memory elements to indicate different types of seizures for a subscriber call such as, for example, a call set up over an incoming trunk line, a call completion from a pulse code modulation switching matrix network over a line trunk group to the selected subscriber and the like which produce different degrees of traffic load for a central control unit or a group control unit. The overall traffic load measurement takes the traffic load to be anticipated with each individual seizure into consideration. Particular application as the group control unit is provided because the balancing effect of statistical averaging is substantially eliminated.

Abstract: A method for producing a recombinant baculovirus expression vector, capable of expressing a selected gene in a host insect cell, is disclosed. The method involves cleaving baculovirus DNA to produce a DNA fragment comprising a polyhedrin gene or portion thereof, including a polyhedrin promoter. A recombinant transfer vector is prepared by inserting said DNA fragment into a cloning vehicle and there-after inserting a selected gene into the thus modified cloning vehicle such that it is under the transcriptional control of the polyhedrin promoter. The recombinant transfer fector is contacted with a baculovirus DNA so as to effect recombination and incorporation of the selected gene into the baculovirus genome. The resultant recombinant baculovirus is then used to infect susceptible insects or cultured insect cells and the protein product from the incorporated selected gene is produced from the infection.
