Title: Improved method and apparatus for printing on concave, convex or other non-planar surfaces
IPC: B41F17/00
Filed: 1947-12-12
Abstract: 646,394. Printing on curved surfaces; offset processes. VALIELA, J. Dec. 12, 1947, No. 32859. [Class 100 (ii)] The convex, concave or other non-planar surfaces of ceramic and other articles are decorated by first printing by means of a silk screen a design on a flexible extensible sheet, e.g. rubber latex and then transferring the printed design to the surface by pressing the sheet into contact with the surface by air pressure. Apparatus for this purpose may comprise (1) a box 1 containing plastic material 2 into which the article 3 to be decorated is embedded ; (2) a tray-like device 5, 11 hinged at 4 to the support for the box 1 and including a perforated plate 6 with the flexible sheet 8 above it secured at the edges 9, and (3) a stencilcarrying frame 14 pivoted at 17 to the support. The frame 14 is first swung down on to the sheet 8 and colour applied to the stencil, and then the tray 5, 11 is turned to overlie the article 3 and secured by a lock 19. Air pressure is now applied to the sheet 8 through a connection 13 to effect the transfer. The space between the sheet 8 and the article may be exhausted in order to cause the pressure of the sheet on to the article. In a modified arrangement, the device 5, 11 fits on but is not hinged to the box 1.

Title: Improvements in or relating to the correction or synthesis of electrical waveforms

Abstract: 1,009,067. Wave-shaping networks. POSTMASTER GENERAL. Aug. 23, 1963 [Aug. 27, 1962], No. 32869/62. Heading H3U. An echo waveform corrector or synthesizer comprises means for applying to the output a time-coincident replica of the main output signal of such magnitude that the algebraic sum (i.e. the sum of the moduli) of all the signals applied to the output is zero whereby D.C. magnetization of the core of the output transformer is minimized. An input S is applied to two delay lines DL1, DL2 coupled in cascade by a hybrid network H from one terminal of which a main output signal is applied through an attenuator PV1 to a tapping of winding W1 of output transformer TR1. To the other winding W2 are applied replicas of the input signal ("echoes")  which are derived from tappings on the delay line and which are, in consequence, either retarded or advanced with respect to the main output signal. Both the amplitude and the sign of these signals may be controlled by means of potentiometers PVa- PVn and PVA-PVN which have their fixed terminals connected to the winding W2 and their sliders to the delay lines via series resistors. The output consists of the sum of the main signal and the echoes and is fed to a load Z2. Net D.C. magnetization of the core of the transformer is prevented by feeding to the winding W2 a signal coincident in time with the main output signal and of such a magnitude to correct the magnetization. Such a signal may be derived from the hybrid network H and adjusted by the potentiometer PV2. Where the network is used for television, a " pulse and bar " test signal may be used for adjustment, such a signal containing a linerepetition frequency band which is sufficiently low to be considered D.C. for this purpose, i.e. although the p.d. across windings W1, W2 can be zero only for zero frequency, a low frequency will give rise to a minimum p.d. A reference signal from the input and an error signal from the winding W2 are fed respectively through amplifiers AMP1, AMP2 and band-pass filters BPF1, BPF2 to a phase-sensitive detector PSD which delivers a D.C. output whose magnitude and polarity depends on the magnitude and polarity of the error signal with respect to the reference signal. The output is used to drive the potentiometer PV2. As an alternative, a variable balance may be used to replace the fixed balance Z3. The variable balance may be a potentiometer connected to the winding W1 with its slider earthed. An out-of-balance signal in the winding is produced by adjustment of the slider and is coincident in time with the main signal. The time constant of the output transformer is preferably made five times as great as the time range occupied by the system of echoes. Specification 823,608 is referred to.

Title: Partial oxidation of hydrocarbons
Inventor: BECKER MITCHELL
IPC: C07C29/52
Filed: 1965-01-12
Abstract: In a process for the liquid phase partial oxidation of a hydrocarbon to an alcohol using molecular oxygen and in the presence of a dehydrated form of ortho-boric acid, the oxidation is carried out continuously in a plurality of reaction zones, the hydrocarbon feed being introduced in a first reaction zone, the liquid reaction mixture being passed from each reaction zone to the next and being withdrawn from the final zone, a molecular oxygen-containing gas being fed in parallel into each reaction zone, a vapour effluent being withdrawn from each reaction zone and unreacted hydrocarbon being recovered from the vapour effluents by condensation and returned to the reaction system. The reaction mixture from the final zone is hydrolysed to liberate the alcohol from its borate ester and the boric acid residue may be recovered, dehydrated and recycled. The dehydration may be effected by contacting the boric acid residue with the vapour effluents from the oxidation zones at 100-160 DEG  C. Preferred hydrocarbons are saturated C4- 8 hydrocarbons, particularly cyclohexane.  The process is illustrated by reference to drawings (not shown) of a schematic flow diagram in which three reaction zones are used.
