Abstract: The mechanism comprises a piston and cylinder assembly operable to move mould side portion supports between mould open and mould closed positions thereof. Check valve means (72, 74, 76, 78, 80, 82) is mounted in a passage (66) into the cylinder to allow fluid under pressure to enter the cylinder through the passage but to prevent exit of fluid through said passage. The check valve means is mounted in a chamber (66f) defined partially by the end cap (60) and partially by a cover member (67) removably mounted on the top of the end cap (60). When the cover member (67) is removed from the end cap (60), the check valve means can be removed.

Abstract: The method comprises developing a presensitized plate for use in making lithographic printing plates imagewise expopsed to light with an alkaline developer utilizing an automatic developing machine and then treating the developed presensitized plate with a finisher, wherein an initial pH of the finisher ranges from 2 to 8 and a pH of the finisher is controlled during running in proportion to concentration of the developer included in the finisher. A formula relating pH to concentration is disclosed. The method makes it possible to prevent the formation of gel-like insoluble matters in the bath for treatment with the finisher due to the presence of the developer carried over from a developing bath and to stably process a large amount of lithographic printing plates over a long time period.

Abstract: An automatic gain control circuit for an amplifier (105) operating over a prescribed frequency range detects the output level of the amplifier (125) and couples a repeated predetermined waveform occurring at a rate greater than twice the upper frequency of the prescribed frequency range to the output level signal. The waveform varying level signal is compared to a reference threshold to control the gain of the amplifier through a switched resistive element (115, 140) in the amplifier feedback path. The repeated waveform variations about the amplifier output level causes the value of the switched resistance to vary as a function of the output level. A low pass filter (120) connected to the amplifier output removes switching transients resulting from the high frequency changes in the switched resistive element. The gains of a plurality of amplifiers may be determined by a common control for accurate tracking over a wide dynamic range.

Abstract: A differential protection device comprises a torus 12, bearing two secondary windings 14,16 connected in opposition and fed alternately by a current supply 22. A flip-flop 28 alternately controls the excitation of the secondary windings 14, 16 until the torus 12 arrives at saturation point which is detected by a sudden variation in the current. A detector (30) of the derivative of the current in relation to time transmits a clock signal from the flip-flop 28 to stop the excitation of the corresponding secondary winding  14,16 as soon as the saturation point of the torus 12 is passed. A differential fault signal is detected by comparison of the excitation times of the secondary windings 14,16. <IMAGE>

In the modification, a selected number of the bits of the idle character are held invariant, and only those bits are varied which form data characters according to the rules of the 8B/10B encoding method. Code points for a total of 124 modified idle characters are disclosed to which a separate command or response may be assigned.

Abstract: A ring latency timer provides a station attached to a token ring network with the capability of obtaining an accurate latency measurement of the ring to which it is attached. An internal hardware register, which may be read via the processor control bus interface, contains the latest ring latency measurement. A latency interrupt bit, when cleared, enables the latency measurement function. A subsequent interrupt which causes the latency interrupt bit to be set by the chip signals the completion of the latency measurement and the function is once again disabled. The latency register holds the latency information until the interrupt bit is cleared by the processor.

Abstract: The present invention relates to the preparation of aminoalkyl p-hydroxyphenyl ketones. Certain of these ketones are well known as important intermediates in the production of compounds having pharmaceutical activity, for example octopamine or synephrine. 
     The known Houben-Hoesch reaction is a variation of the Friedel-Crafts reaction and involves the condensation of a phenolic substrate with a nitrile in the presence of a Lewis acid catalyst to give a hydroxy-aryl ketone. 
     It is an object of the invention to provide a new or improved process for the manufacture of aminoalkyl p-hydroxyphenyl ketones. 
     According to the invention, there is provided a process for the preparation of an aminoalkyl p-hydroxyphenyl ketone comprising reacting phenol with a nitrile, in the presence of a Lewis acid catalyst, to cause condensation thereof, the process being characterised in that the reaction is carried out in a medium comprising a nitroalkane solvent for the reactants. 
     A preferred but non-limiting feature of the invention is the productiqn of 2'amino-4-hydroxyacetophenones. 
     The present invention is based on the surprising discovery that nitroalkanes are unexpectedly much better solvents for this reaction, being less toxic, giving a better yield and also ensuring a homogeneous reaction medium. The nitroalkanes may also be diluted with a halogenated hydrocarbon solvent, which acts as an inert diluent, thus reducing the amount of nitroalkane used, and making the reaction less hazardous.
