Title: Improvements in Numerical Control Devices
Inventor: POMELLA PIERO
IPC: G05B19/4103
Filed: 1968-08-02
Abstract: 1,189,959. Programmed control of machine tools. ING. C. OLIVETTI & C. S.p.A. Aug.2, 1968 [Sept.19, 1967], No.36933/68. Heading G3N. A numerical control device for positioning a movable part along one or more axes comprises a programming unit adapted to furnish the coordinates of break-points of a segmented path to be followed by the movable part, and an interpolating unit arranged to operate cyclically to compute, in respect of each axis, a co-ordinate for controlling a servosystem for each axis by accumulating in each cycle a variable position increment to control the speed and acceleration of the movable part. The interpolating unit is adapted to cause a break-point to be traversed without stopping, by arranging that the final part of one segment of the path and the initial part of the next segment is traversed at a constant speed by pre-computing during travel along the one segment the speed along each axis at which the initial part of the next segment is to be covered. The device employs an interpolating unit as disclosed in Specification 1,154,761 having available in the memory four registers adapted to contain the data relating to the next segment.

Title: Process for the production of fluorine compounds from fluosilicic acid
IPC: C01C1/16
Filed: 1962-10-02
Abstract: Fluosilicic acid is reacted with ammonia in aqueous solution to produce ammonium fluoride and hydrated silica, the ammonium fluoride as such or after conversion to ammonium bifluoride is reacted with alkali metal fluoride in aqueous solution to produce alkali metal bifluoride and ammonia or ammonium fluoride, and the alkali metal bifluoride is thermally decomposed to produce alkali metal fluoride and hydrofluoric acid.  The ammonia or ammonium fluoride and alkali metal fluoride produced are recycled.  A 5-60% stoichiometric excess of ammonia may be added to the fluosilicic acid with vigorous stirring at 30-170 DEG  F. The ammonium fluoride produced may be converted to bifluoride at 250-410 DEG  F. The alkali metal fluoride may be reacted as a powder of less than 70 mesh size. The reaction temperature may be 50-410 DEG F. for the reaction of ammonium fluoride, and 50-170 DEG F. for the reaction of ammoniumbifluoride. Ammonium fluoride may be reacted with potassium fluoride at 200-410 DEG  F. to produce directly molten potassium bifluoride and gaseous ammonia. Ammonium bifluoride may be reacted with sodium fluoride at 50-170 DEG  F. to produce crystals of sodium bifluoride which may be separated by decantation, filtration or certrifugation and then heated to drive off water and ammonium fluoride.  The alkali metal bifluoride may be dried at below 550 DEG  F. and decomposed at above 575 DEG  F.  The gaseous hydrofluoric acid produced may be condensed at below 80 DEG  F.

[Also in Groups XXX and XXXII] A luffing boom attachment for a tractor comprises a sub-frame 1,8, adapted to be secured to the tractor chassis, and a pair of arms 12 detachably pivoted at 11 to the sub-frame so that they may extend either forwardly or rearwardly of the tractor. Hydraulic rams 13, controlling the movement of the arms 12, are detachably pivoted to the sub-frame at 14 when the arms extend forwardly, and at 10 when the arms extend rearwardly. The action of the rams 13 may be augmented over the initial range of upward movement of the arms 12, when the arms extend rearwardly, by direct engagement of the tractor lift links, Fig. 14 (not shown). A radiator guard 17 is provided which may be adjusted to serve as a ballast tray when the arms 12 extend rearwardly, a counterweight being attached to the tractor lift links when the arms extend forwardly. The specification describes how the invention can be applied to various well known makes of tractors, with implements 16 such as a fork, scoop, ditching attachment, hole driller or hedge trimmer. Reference has been directed by the Comptroller to Specification 805,425.

A tensioning device for a flexible plate on a saddle of a rotary printing cylinder comprises a tensioning strip mounted on supports along the longitudinal edge of the saddle, the supports being movable towards and away from the saddle under the operation of screw-controlled wedge-shaped sliding pieces contained in the saddle. Fig. 2 is a side elevation, and Fig. 4 an enlarged fragment of the apparatus wherein a printing cylinder 2 supports a saddle 1 for tensioning thin plates 4; the plates 4 have holes 5 in their ends engaging teeth 6 carried on a tensioning strip 7, the strip being mounted on support arms 8 sliding in slots 9 formed in the saddle, the slots being of such a dimension as to allow for some lateral movement, i.e. parallel to the longitudinal edge 10 of the saddle. Further grooves 11 formed in the saddle contain wedgeshaped sliding pieces 12, the oblique faces 13 of which co-act with oblique faces on the ends of the support arms 8; thus movement laterally of the sliding pieces 12 causes perpendicular movement of the support arms, and hence of the tensioning strip 7. The sliding pieces, four to each saddle, are under the control of screws 14, each of which can be operated independently, if required to slew the plate. An alternative embodiment (Fig. 6, not shown) has each pair of sliding pieces movable simultaneously under the action of a single screw (16), guided in a slide (17) which can be displaced in a longitudinal direction when it is required to slew, or laterally shift, the plate.
