Title: Improvements in or relating to the partial oxidation of hydrocarbons
IPC: B01J21/02
Filed: 1963-12-09
Abstract: In a process for the partial oxidation of a hydrocarbon (e.g cyclohexane to cyclohexanol and cyclohexanone) with O2 in presence of a B compound, in which the resulting borate esters are hydrolysed giving an organic product phase and an aqueous phase, H3BO3 of particle size 100-1000 microns is crystallized from the latter, separated, passed to a dehydrator, formed into a slurry in an organic medium, and heated to give a slurry of HBO2 of crystal size 3-60 microns which is then withdrawn.  In practice, the organic medium is the hydrocarbon and the HBO2 slurry is recycled to the oxidation. Other specified hydrocarbons are methylcyclohexane, cyclopropane and cyclooctane.ALSO:Metaboric acid of crystal size 3-60 microns is obtained by hydrolysing orthoborate esters, separating an aqueous phase from an organic phase containing alcohol (e.g. cyclohexanol), crystallizing H3BO3 of particle size 100-1000 microns from the aqueous phase, separating, passing to a dehydrator, forming into a slurry in an organic medium (e.g. cyclohexane) and heating to give a slurry of the desired product.

Title: Ink duct for offset or relief printing presses
IPC: B41F31/04
Filed: 1977-11-22
Abstract: The ink duct has an ink metering device with adjusting elements. Using the latter, the gap opposite the ductor roller can be adjusted differently in zones. The ink duct (1) is covered by an elastic film (11) which is easily removable; the film is fixed in the upper region (12) of the ink duct (1), for example by an adhesive film (23) or clamping means. This dispenses with complicated cleaning of the ink duct; it is sufficient to exchange the film for a new one. <IMAGE>

Title: Civil engineering machines

Abstract: 1488265 Grab machines POCLAIN 12 Nov 1974 [21 Nov 1973] 48916/74 Heading E1F [Also in Division G3] In the control of a grab machine, the angle 12a, or 12b between the grab 4 and boom 3 is retro-actively controlled in subordination to the rotation angle 11a, or 11b with respect to reference direction 7 of turret 2 supporting the boom, so that the grab is presented parallel to the axis 5 of a trench or elongate hole for loading, or to that, 6, of a train of trucks, or a lorry, for unloading. Angles 13, 14 between the loading, and unloading axes, and a reference direction 7, as well as that, 10, between the reference direction and the direction 9 of a line joining the boom rotation axis 2a and intersection 8 are preset in units 20, 21, 18. The actual turret rotation angle 11 is compared in unit 17 with the setting 10, either one of outputs 11a, or 11b being delivered: in dependence on the relative magnitudes of 10 and 11: to calculator 19, which, using disclosed algebraic analysis provides a desired boom/grab angle 12a, or 12b, to comparator 22 providing an angle error signal 12-12 to grab drive 24, signal 12 being an actual boom/grab angle. Turret rotation drive 15 is coupled to pickup 16 providing the actual turret angle signal 11. When both loading, and unloading zones are localised, (25, 26), Fig. 3 (not shown), turret rotation angles (30, 29) for loading, resp. unloading not substantially varying, the outputs 11a, 11b of the comparator may control the selection of one, or the other (27, 28) of pre-set boom/grab angles to be fed to the comparator 22. The turret rotation angle 11 is fed to comparator (34), Fig. 4 (not shown) receiving pre-set values of the angles (30, 29), the comparator output ensuring that the turret, having been started by controls 15a, or 15b, is stopped at the orientation (30) or (29). The machine may have a telescopic boom.

Title: Apparatus for rapid action displacement control
IPC: G05D3/14
Filed: 1971-10-21
Abstract: 1366124 Digital control systems XEROX CORP 21 Oct 1971 [23 Oct 1970] 48938/71 Heading G4H An object in moving from a present to a desired position, such as the read/write heads of a magnetic disc store, first accelerates till the velocity of the object equals the velocity represented by a control signal derived from the actual position of the object to the desired one and then decelerates at the same rate as the acceleration to approximately reach the desired position. Such coarse control of the object is digital which is followed by a fine analogue control. In Fig. 1 read/write heads 11 of a magnetic disc store 12 are supported on a carriage 10 moved by a linear motor 15. A computer 20 supplies in parallel form a new position to which the read/write head must move and its distance from the present position in register 24 is obtained by subtraction circuit 25 and fed in serial form to counter 30. The output of the counter is converted to an analogue signal y and in a function generator 33 is converted to a velocity signal represented by the square-root of the product 2ay, where a is the stabilized acceleration or deceleration rate of the read/write heads. Depending upon the sign of the subtraction circuit output, a velocity signal is either inverted in inverter 34 or not and then compared in summer 35 with the actual velocity of the read/write heads derived from tachogenerator 42. When the velocity signal is greater than the actual velocity of the read/ write heads amplifier 40 saturates and the resistive feedback loop 41 maintains a constant acceleration. Displacement enclosure 50 coupled to the read/write carrier 10 supplies an alternating signal which after phase shifting and shaping to a square wave counts down counter 30. When the velocity of the read/write heads equals the velocity represented by the ever decreasing velocity control signal the read/write heads then begin to decelerate at the rate stabilized by feedback network 41. Upon the counter reaching zero the read/write heads are very near to the desired position, and would be but for a lag in the system, zero detector 55 opens FET gate 56 to direct the analogue output of the encoder 50 to the summer 35 to affect fine analogue control. If the read/write heads should overshoot too much during fine analogue control phase detector 58 and control circuit 60 cause counter 30 to count up and therefore switch to digital control. A limiter 31 would limit the distance signal y if the distance to be traversed is long and therefore will generate an unacceptably high velocity control signal. The result is a period of constant velocity after the acceleration period until the output of the counter is below the threshold of the limiter 30 when deceleration begins.
