Flow is also throttled by an adjustable restrictor in pipeline 43. The cylinder 5 is rigidly attached to a further cylinder 27 which, when the pressure in the chamber 7 builds up, slides in a cylinder 1 to compress air in a chamber 33 to provide an additional braking force. A reservoir (37) and a motor driven pump (38, Fig. 1) are mounted on the cylinder 27 and with rigid pipelines 41-43 make up the hydraulic circuit. An endless motor-driven chain (47, Fig. 1) and liquid supplied to chamber 7 from the pump (38) adjust the positions of cylinders 27 and 5 and the container for loading/unloading and then return them to the initial contact position. Liquid supplied to the chamber 8 through pipe 41 releases the spring grip 12 and accelerates the container back into the pneumatic-conveying tube, leaving the buffer ready for the next container impact.

The mercury compound may be added to the emulsion at any stage prior to chemical sensitization, preferably immediately before chemical sensitization. The mercury compound may be mercuric bromide, (2-amino-5-iodopyridine hydroiodide) 2  HgI 2 , bis-(2-methyl-benzothiazole hydroiodide) HgI 2  or triphenylguanidine hydroiodide HgI 2 . The silver halide may be silver bromide and the grains may be cubic. The emulsion may contain gelatine or an acylated gelatine e.g. phthalated gelatine (see Example 2). The addition of the mercury compound prevents high fog levels developing during manufacture of these monodisperse emulsions.

Rotary member 4 includes packetengaging pivoted arms 9 actuated by cam followers 10 which engage a fixed cam 11. Rotary member 5 is similar to member 4 but its peripheral speed is greater than that of member 4 as is the speed of member 6 relative to member 5. Member 6 has cam operated arms 17 which urge the packets against an annular plate 17a. In operation, packets fed by gravity at 1 are deflected towards the rotary member 4 and spaced from each other by the rotary member 3 and guide 19. Each packet is then gripped between an arm 9 and a fixed stop 8 of the rotary member 4 for transfer to an arm 13 and fixed stop 12 of the rotary member 5. As the packet leaves the member 5 it is dragged back against a stop 18 of the rotary member (i by stationary guide brushes 20 and an arm 17 is then actuated to hold the packet on the member 6.

Abstract: 1337891 Bridge for core storage read out STANDARD TELEPHONES & CABLES Ltd 2 March 1972 9727/72 Heading G1U [Also in Division H3] In order to determine when the "read" current applied to a ferrite-core M, Fig.1, reaches 80 per cent of its maximum value - since it has been found convenient to strobe the "sense" output at a fixed time after this instant - the core read winding is connected in series with one arm of a bridge P, Q, R, S, balanced, with respect to a voltage source V, in such a way that the balance current I through each arm equals the required maximum read out current for the core, and such that Q is considerably less that P, and an additional current i = 0.20I is injected into the. bridge as shown thereby effectively applying a bias potential across the arm Q, so that when a contact S1 is closed to initiate a core read out pulse, a detector e indicates balance at the instant the current through the core equals 0.8I, since at this instant the current through Q will equal 0.8I plus the bias current i of 0.2I, and hence the potential across Q will equal the potential across S. The detector can be arranged to trigger a monostable device so as to generate the required strobe pulse.

Abstract: The present invention is concerned with a method for generating, in a non specific manner, multiple copies of RNA from a pool of mRNA's. Such a method is of particular importance in techniques for screening the differences in expression in given cell types or in cells under specific conditions. The present invention provides a non-selective poly A mRNA labeling and amplification method, i.e. a method not encompassing cDNA synthesis. The present invention is directed to a method for amplifying RNA by creating, in a non specific manner, multiple RNA copies starting from nucleic acid containing starting material comprising a pool of mRNA's each mRNA comprising a poly-A tail, wherein the material is contacted simultaneously with an oligonucleotide comprising an oligo-dT sequence, the sequence of a promoter recognized by an RNA polymerase and a transcription initiation region which is located between the oligo-dT sequence and the sequence of the promoter, and further with an enzyme having reverse transcriptase activity, an enzyme having RNase H activity and an enzyme having RNA polymerase activity and the necessary nucleotides and the resulting reaction mixture is maintained under the appropriate conditions for a sufficient amount of time for the enzymatic processes to take place. In a preferred method of the invention the generated RNA copies made are contacted with an RNA ligase, a double stranded nucleic acid complex comprising a double stranded DNA promoter sequence that can be recognized by an RNA polymerase, whereby one strand of said complex has a stretch of RNA attached to the 5' end of one of the DNA strands, an enzyme having RNA polymerase activity, and the necessary nucleotides. The resulting reaction mixture is maintained under the appropriate conditions for a sufficient amount of time for the amplification to take place.
