Abstract: The production of esters via the reaction of an epoxide with a carboxylic acid has been shown to give improved activity when a strong base macroporous anion exchange resin having an acrylic backbone is used in place of a styrene-divinylbenzene based anion exchange resin having an equivalent exchange capacity. Excellent results are obtained when acrylic acid and propylene oxide are reacted together in the presence of strong base macroporous anion exchange resins which have an acrylic backbone.

Abstract: A memory cartridge according to this invention is mounted removably to a D processing device such as a portable electronic game machine containing a CPU, and contains a programmable ROM (PROM) and a bank switching circuit, and an external RAM is contained in the bank switching circuit. The external RAM is backed up by a cell. First and second key data are previously written into the PROM. After power supply is switched on, a reset signal is outputted when the power-supply voltage reaches a given value. When the first key data is read from the PROM and also a reset signal is outputted the external ROM becomes accessible by the CPU. When and after the second key data is read from the PROM, access by the CPU to the external RAM is prohibited.

Abstract: 1. Gas-insulated switchgear for use in mains distribution stations. 2.1 Gas-insulated switchgears are particularly suitable for use in areas where the conditions are confined. The reduction in size of the gas tank with the load interruptor switches located therein leads, however, to a number of problems during assembly. The object thus exists of developing a gas-insulated switchgear which eases the installation of the individual parts and reduces the assembly cost. 2.2 The solution provides that the contacts (4) of the busbar (2) for one phase of a plurality of load interruptor switches are in each case mounted on a transverse support (3) connected to the busbar (2), that each transverse support (3) rests on a retained (6, 19) support (5), that extinguishing chambers (7) for the individual phases are in each case connected directly to busbars (2), and that each busbar (2) is constructed with three transverse supports (3), three contacts (4), three supports (5) and two retaining devices (6) to form a prefabricated assembly which can be inserted into the gas tank (1), which is initially open on the rear side (17), and that the three earthing contacts (9) belonging to the earthing device are mounted on each switch shaft (8). 2.3 Gas-insulated switchgears are preferably suitable for mains distribution stations which have confined spatial conditions. <IMAGE>

Abstract: Dosing pumping of liquid-state contents for e.g. packaging containers results in a varying rate of flow in the product pipe, which entails pressure shocks which must at some stage be reduced with the aid of further devices, e.g. compensation vessels or the like. One way of pumping a pumpable product by means of a dosing pump unit (1) entails that two individually driven pump chambers (2, 3), which are connected with a common outlet (6), are controlled in such a way that the suction phases of the pump chambers overlap each other so that the total inflow to the pump unit is maintained constant. A pump unit to make this possible comprises two pump chambers (2, 3) which have a common in- and outflow (5, 6), which are controlled by a rotable valve body (4), whose inlet passage (18) surrounds such a large part of the circumference that it at the same time connects the inlet (5) with the pump chambers (2, 3). <IMAGE>

Abstract: A semiconductor memory device is subjected to a test operation, before delivery from the factory, for screening defective products. The device is placed in a diagnostic mode for carrying out the test operation on the signal circuits (23 to 32) when a discriminator (33) produces an internal control signal (EBL) for the test operation. The data and power signals (CS/ WE/ A1 to Ax/ A1 to Ay) supplied to the device pins have active levels within a predetermined voltage range. The discriminator is responsive to a test signal (TS) received at a test pin and is activated at a level which lies outside the predetermined voltage range. Thus the semiconductor memory device does not mistakenly enter the diagnostic mode after being assembled in an electronic system. <IMAGE>

Abstract: A method of incorporating an exo-sample nucleotide (e.g. deoxyuridine in DNA) into amplified product strands resulting from a nucleic acid amplification process is disclosed. Once the product strands have been obtained and analysed (e.g. by hybridisation, Southern blot, etc.), the exo-sample strands can be selectively destroyed by acting on the incorporated exo-sample nucleotide. Two procedures are described. In the first procedure the exo-sample nucleotide is incorporated by conducting the amplification reaction in the presence of an excess of exo-sample nucleotide triphosphate. In the second procedure the exo-sample nucleotide is incorporated by conducting the amplification reaction in the presence of an oligonucleotide which has, as part of its sequence, one or more exo-sample nucleotides. <IMAGE>
