Title: Process for the preparation of phthalocyanine pigments
IPC: C09B67/12
Filed: 1975-03-24
Abstract: The new crystallisation-stable copper phthalocyanine pigment is obtained by milling a crude copper phthalocyanine in the absence of crystallising solvent and by treating the phthalocyanine produced by the milling and which is of nonpigmentary nature with a crystallising solvent in the presence of a stabilising phthalocyanine compound. The phthalocyanine pigment thus prepared is employed in pigment compositions. These preparations offer the advantage of practically retaining their crystallinity, their colouring efficiency and their viscosity with time.

Title: Apparatus for weighing and discharging alloy constituents
Inventor: KING ROBERT
IPC: G01G19/22
Filed: 1955-04-27
Abstract: 799,483. Weighing apparatus. IMPERIAL CHEMICAL INDUSTRIES, Ltd. April 25, 1956 [April 27, 1955], No. 12125/55. Class 143 Alloy ingredients are fed in predetermined proportions to a melting furnace (not shown) by automatic feed weighers A, B the vibratory feeders 5, 6 of which are stopped when the associated weigher has operated and are restarted only after both the weighers have operated. Each weigher comprises a valve 9, 30 supported on a stem 10 by an electromagnet 13, 31 which is overcome when the weight of material on the valve reaches a predetermined value so allowing the valve to open and discharge the weighed portion of ingredient into a common pipe 23 which is closed by further valve 27 forming part of a similar weigher set to discharge under the total weight of material delivered by weighers A and B. Initial movement of stem 10 operates a micro switch 15 which de-energizes the associated vibrator and also, by de-energizing the associated electro magnet 13 or 31 and energizing an electromagnet 16, accelerates opening movement of the valve. When each valve is fully open a beam 18a closes an associated micro switch 20 or 29 each of which is in series with a further micro switch (not shown), which is closed when valve 27 opens, and a relay (not shown) which, when operated, re-energizes the electromagnets 13, 31 and vibrators 5, 6 so restarting the cycle. The ingredients are fed to the furnace by a vibrator 25 and pipe 26. Rods 10 are provided with weight pans 22 which facilitate adjustment of weigher A, B. In various modifications (not shown) (a) the accelerating electromagnets 16 act directly on rods 10, (b) a cylindrical shell mounted within tubes 7 for limited longitudinal movement prevents material sticking to the side of the tube, and (c) valve 27 is dispensed with.

Filed: 1969-03-07
Abstract: 1,247,436. Papermaking. BELOIT CORP. 7 March; 1969 [8 April, 1968], No. 12189/69. Heading D2A. A papermaking machine has a headbox with a pair of integral slice lips, and means for actuating the lips so that they vibrate at substantially their resonant frequency. This may be achieved by a mechanical coupling between one of the lips and a mechanical oscillator. Alternatively, the flow of liquid through the lips may be pulsated, e.g. by a transducer coupled to an electrical oscillator. In both cases, the oscillator may be adjustable as to its frequency. The headbox may also include an agitating roller. By energising the lips so that -they vibrate at their resonant frequency, flow through then is improved.

Title: Improvements in or relating to position encoding apparatus
Inventor: LANCASTER KENNETH
IPC: G01D5/252
Filed: 1959-04-10
Abstract: 883,596. Electric selective-signalling systems. GENERAL ELECTRIC CO. Ltd. April 4, 1960 [April 10, 1959], No. 12202/59. Class 40 (1). A shaft digitizer is characterized in that one track is sensed by a plurality of heads which give an output representing, in combination, the position of the shaft. In the preferred embodiment magnetic sensing is used but it is stated that sensing could be photo-electric. A typical track, as described, comprises, Figs. 1 and 2, ten pairs of teeth 26 cut on the edge of a disc. The teeth are regularly spaced around the disc, as shown, and are sensed by an E-type head 34, Fig. 3. The central limb of the head receives a steady A.C. signal which is inductively coupled to either the left or right limb, depending upon the position of the disc, to give an output signal either in phase or out of phase with the input signal. The track shown is sensed by five heads 29 to 33 positioned as shown in Figs. 1 and 4, Figs. 4a, 4b and 4c showing the disc in three slightly different positions. The heads are so arranged that as the disc rotates through one-tenth of a revolution the output signals produced by the heads go through a complete cycle of ten different combinations which are repeated as the disc turns through the next tenth of a revolution. Six of these discs, connected by appropriate gearing, are used to give six decimal digits representing the position and shaft. Transitional errors are avoided by arranging that each of the six decimal digits is monophylically represented and by having lead and lag sets of heads for each track (except the lowest denominational track) controlled by the immediately preceding disc.
