Title: Improvements in and relating to the production of transfer coatings on paper or the like sheets and webs
IPC: B41L1/00
Filed: 1931-11-18
Abstract: <PICT:0389185/III/1> The process according to the parent Specification for the hot printing of transfer composition on paper or like sheets and webs, is modified by effecting the impression by a printing-device wherein the areas for applying transfer composition are formed by a screened intaglio pattern, produced by photo-engraving, the printing-device operating with a scraper to remove excess transfer composition from the relief portions of the device prior to printing.  The lines of the screened pattern rise to the level of the smooth non-printing parts of the surface and are preferably arranged in two directions at right-angles.  The engraved designs may be formed on a copper plate which is then attached to the surface of the cylinder by clips, pins &c., or a copper covering may be formed on the cylinder by electroplating.  One side of a pre-printed web may be wholly or in part coated with transfer composition or, as shown in the Figure, both sides may be so treated, two printing-cylinders 16, 25 being used.  Cooling may be effected by a cooled cylinder 20 or by blowers 29 adjustably mounted in relation to the web.  The cylinder 20 may be adjustable so that the pressure of the web on the roller 16 can be varied, and rollers 19, 28 may be similarly used.

IPC: C10B57/08
Filed: 1928-08-13
Abstract: 309,231. Cranston, W. M. Aug. 13, 1928. Coking processes.-Coal is distilled at low temperature in two steps by being first ground and mixed with a mineral oil and heated to about 180‹ C. in one retort, the distillation products being collected, the second step consisting in cracking the oil contained in the residue in a second retort, which is heated to between 300‹ and 500‹ C. The pressure in the first retort is maintained at two inches below atmospheric and in the second retort at about 20 lbs. or more above atmospheric. Water or superheated steam is introduced into the second retort to effect hydrogenation of the unsaturated hydrocarbons and to reduce the temperature at which distillation and cracking takes place. If a horizontal retort is used nickel or iron stirrers or a trough made of these metals may be employed to promote catalytic action.

Abstract: 1452854 Velocity transducers: moving coil meters SYSTRON-DONNER CORP 22 July 1974 [31 July 1973] 32353/74 Headings G1N and G1U [Also in Division G4] A transducer for measuring angular acceleration comprises two blades 50 Figs. 3 and 4 diametrically supported vertically by pivots 48, 49 adjacent one or more sensing coils 69, in a fluid 42, whereby an angular acceleration about the vertical axis produces displacement of the blades 50 relative to coil 69 and an output signal is obtained from coil 69 which is rectified and fed back to the rotor coil 51  of a motor 52 to restore the blades 50 to their normal position relative to coils 69. The output signal from the acceleration transducer 11 Fig. 6, constituted by the restoring current of motor 52, is integrated at 79 to provide a D.C. velocity signal which is dropped by transistor Q 1 to convert it to a corresponding A.C. in phase with the mains supply. A timer circuit 82 produces a pulse every two seconds which acts through circuit 83 to shortcircuit the integrator 79 for 0À2 seconds and reset the output voltage to zero. If the D.C. velocity signal exceeds a pre-determined value a diode network 84 causes transistor Q2 of timer 82, and chopper transistor Q1, to conduct continuously and the A.C. velocity signal is inhibited. The circuitry is checked by applying a known voltage pulse to the input by closing and opening switch 78. The motor 52 comprise a moving coil 51 in the gap between a magnet 53 and a cylindrical soft iron shell 54 with polepieces 55, which completely surrounds the coil 51. The coil is supported between jewelled pivots 48, 49 mounted on leafsprings 56 Fig. 5 attached at one end by screws 57 to a cradle 47, fixed to the housing by screws 46, and positioned by coil springs 58 adjustable by screws 59. Connections to the coil 51 are made through hair springs 61. The assembly is balanced by weights 62 and is located within the fluid 42 of the accelerometer described above.

The reactance of the conductors in the groups is greater for the inner conductors such as 1 and 4 than it is for the outer conductors such as 2 and 3 so that reactance imbalance to the delta connection points 22, 23, 24 can be reduced by connecting certain of the windings to differently placed conductors. Other arrangements are described (Figs. 5 and 7, not shown), and formulµ are given for determining connections providing minimum imbalance. The windings such as 1a, 1b may be sub-divided into parallel connected sections. A current transformer may be associated with one of the internal leads 13.
