Title: Improvements in or relating to coating articles
IPC: B05D3/02
Filed: 1937-12-20
Abstract: 507,768. Coating surfaces ; hardening resinons condensation products. BAKELITE, Ltd. Dec. 20, 1937, No. 35287. Convention date, Dec. 24, 1936. [Class 95] [Also in Groups IV and VIII] A method of coating articles comprises immersing the articles successively in a mass of a heat-hardenable coating material in liquid form and then, without intermediate exposure. in a mass of a heating liquid immiscible with the coating material. Specified heat-hardenable coating materials are phenol-aldehyde resins and polyhydric alcohol-polybasic acid resins, in the early stages of formation'. Such substances may be used in the liquid or fused condition, and a small amount of solvent may be present, if necessary. Specified heating liquids are molten alloys, molten wax, oils and other inert relatively non-volatile organic liquids or melted solids. The function of the heating liquid is to promote hardening of the coating material. Fig. 1 shows a conveyer 2 carrying articles 3 through the coating liquid 4, automatically maintained at constant level, and then through the heating liquid 5. Coils 7 are provided for cooling or heating the coating material as desired, and heating coils 6 are preferably arranged so that there is a progressive increase in temperature as the coated article passes through the heating liquid 5. Fig. 2 shows a modified form of apparatus, adapted for use when the specific gravity of the heating liquid 5 is lower than that of the coating liquid 3. The passage of the articles may be continuous or intermittent, and the coated articles may be subjected to a washing operation after emerging from the heating liquid. The method may be applied to the coating of wire and cable, in which case the apparatus would comprise a tube or pipe of small diameter.

Title: Waste heat boiler
Inventor: WOOLLEY ERIC MAURICE
IPC: F01K1/00
Filed: 1960-10-18
Abstract: 935,462. Waste heat steam boilers. HEAD WRIGHTSON & CO. Ltd. Jan. 18, 1962 [Oct. 18, 1960], No. 35746/60. Class 123 (2). In a waste heat boiler installation for maintaining at a constant flow rate a continuous supply of superheated steam to a site main and in which the source of heat supply to the boiler is intermittent, a thermal storage plant is supplied with steam in excess of said flow rate through a control valve which is normally closed but which opens automatically to admit steam to the storage plant when the rate of flow of steam to the site main exceeds said flow rate. In the form shown a waste heat boiler receives heat from a steel converter plant, the boiler comprising a steam drum 1, an evaporator 3, a circulating pump 5, and an economizer 2. Saturated steam is passed from the steam drum 1 through a line 6 to a superheater 7 whence it passes to the site main through a steam main 8. An attemperator 9 under control of a valve 10 ensures that the superheated steam is maintained at a constant temperature. When the amount of steam generated exceeds a predetermined flow rate, as may occur at peak heat imput conditions during the blowing of the converter, a normally closed control valve 13 automatically opens to admit the excess steam to an accumulator 12 which acts as a thermal storage device. The accumulator 12 is preferably designed to accommodate all the excess steam generated during the peak period. However, should the excess steam exceed the capacity of the accumulator a shut-off valve 14 is arranged so that it closes when the pressure in the accumulator reaches a valve corresponding to the pressure on which the design was based. As the valve 14 closes a further valve 16 in a blow-down line 15 is arranged to open to divert the remaining excess steam to atmosphere and maintain the flow rate to the site main at a constant value. The excess steam stored in the accumulator 12 is discharged from the same through a control valve 25 in a discharge line 17 leading to a feedwater heater 18, the valve being controlled by a temperature controller set to discharge the accumulator over a given period to suit the time between flow periods of the converter. The steam entering the feed heater 18 heats the feed water for the boiler and is condensed, the water so formed being led via a line 19 to a feed tank 20. Feed water is fed to a steam drum from the feed tank 20 via a feed pump 24, the feed heater 18 and line 22. Auxiliary firing may be used to heat the boiler if the period between the blow periods is longer than the accumulator can accommodate.

[Also in Division G2] The derivative spectrum of a sample (i. e. the plot of the first differential of the absorbance of the sample against wavelength) is obtained by producing a pair of mono-chromatic light beams B, B<SP>1</SP> having the same spectral band width, masking part of each beam, using aperture masks M, M<SP>1</SP> , so that the unmasked portions of the beams have particular wavelengths which differ from one another by a small amount, passing these portions through respective cells C, C<SP>1</SP>, both containing the sample under investigation, and detecting the light transmitted by the cells. The outputs from detectors 23, 23<SP>1</SP> (which may be photo-multipliers) are compared to produce a ratio, which is converted to a logarithmic value, and plotted, while the wavelength of the original spectral band width is changed. In the derivative spectrum produced, features such as overlapping absorption bands of a sample show up more clearly than in the usual absorption spectrum Figs. 1-3, (not shown). The optical system includes a source 10, a mirror system 11-13 leading the beam into the prism monochromator 14 which produces the required beam. This is split into the two equal wavelength beams B, B<SP>1</SP> by splitter 19 after collimation and chopping at 17,18 respectively.

Abstract: 862,397. Typewriters &c. OLYMPIA WERKE A.G. Nov. 20,1957, No. 36145/57. Class 100(4) A typewriter having an electric motor for carriage return, and mechanism actuated by the inertia of the carriage starting, to cause . line spacing with carriage return has a locking lever to prevent carriage return when line spacing alone is required. In the two embodiments described the motor and clutch for effecting carriage return are actuated by key controlled relays and line spacing occurs before any movement of the carriage due to its inertia. When line spacing alone is required a key 5 is depressed closing contacts 6 which actuate the relays in the same way but at the same time a locking lever 37 pivoted at 38 on a supporting lever 35 is rocked so that its detent enters a starwheel 33. As the carriage return motor starts it causes line spacing in the usual way and its drive on the starwheel 33 deflects the lever 37 against a spring 40 causing it to open contacts in the relay circuit to stop the motor. The spring 40 then restores the carriage re-closing the contacts in the relay circuit but holding circuits prevent further operation of the relays until the key 5 is released and again depressed.
