Title: Improvements relating to the cooling of the grate bars of furnaces
IPC: F23H3/02
Filed: 1928-03-24
Abstract: 287,580. Lomshakoff, A. S. March 24, 1927, [Convention date]. Addition to 214,640. Grates; air supply, regulating; ashpits.-The underside of the main portion of each grate bar of the parent invention is enclosed by a casing such as 4 so that all the air supply for the bar from the ashpit is compelled to pass through a conduit 7 at the rear of the cross piece 6 which is thus effectively ecoled. Where extra high pressure is used the casing 4 may be shortened as shown at 4<1>, so as to relieve the passage 7 by allowing some of the air to reach the grate bar direct. The casing 4 is mounted on the frame 8 which carries the rods 9 by which the grate bars are reciprocated and makes joint with the grate bar (or grate bars) which it serves, by means of the channels 10. Any ash dropping through or between the bars collects in the casing 4 and is conveyed away by a pipe 11 (or 12 Fig. 4) into a chamber 13, Fig. 3, forming the base of the lowest step (or the two or more lowest steps) of the grate. The forced or exhaust draught air current in which the ash is thus carried, being released in the chamber 13, may serve as combustion air for the corresponding grate unit, though a cut-off valve 19 is fitted so that a separate air supply at 16 may be used if desired. Ash is withdrawn at 17. In a modification, Fig. 4, the enclosing casing takes the form of a plate 21 secured to the grate bar and delivering into a channel 22 arranged beneath the driving bar 9. In this case the direct air supply designed to relieve the channel 7 is at 25.

Patent GB-707120-A (GB)
Title: Production of organic acid esters of cellulose
IPC: C08B1/02
Filed: 1952-04-09
Abstract: Cellulose is subjected to a pretreatment with a mixture of an aliphatic acid, containing 1-4 carbon atoms per molecule, and an acid esterification catalyst, the amount of the catalyst being 7.5-25 per cent. of the weight of the aliphatic acid, in the presence of 8-20 per cent. of water (on the weight of the aliphatic acid), and the pretreated cellulose is then subjected to esterification, e.g. with an aliphatic acid anhydride.  The aliphatic acid may be formic, acetic, propionic, or n-butyric acid, or a mixture of two or more of these acids.  The esterification catalyst is preferably sulphuric acid.  Preferably the amount of water present during the pretreatment is 4-7 per cent. of the weight of the cellulose, the amount of aliphatic acid is 35-45 per cent., and the amount of acid esterification catalyst is 4-8 per cent. of the weight of the cellulose.  Cotton linters, purified wood pulp, and cellulose derived from bamboo, reeds, jute, esparto, straws, grasses, peanut hulls, and bark may be used.  The cellulose may be in the form of a mass of loose fibres, or it may be in the form of sheet, strip, or board. The temperature may be 20-50 DEG C. during the pretreatment, which may last for 5-40 minutes.  The pretreated cellulose is preferably brought into contact with a pre-cooled esterification mixture so as to prevent excessive rise in temperature at the start of the reaction.  An acetylation mixture containing acetic anhydride and acetic acid is preferably cooled to a temperature such that at least part of the acetic acid is frozen.  Esterification may be completed in 15-30 minutes.  Both the pretreatment and the esterification may be carried out in a continuous manner. Specifications 665,725 and 706,522 are referred to.

Abstract: 1339873 Rolling wheels J M PLAGEMANN [trading as PEE-WEE MASCHINENUND APPARATEBAU WERNER PLAGEMANN] 28 Feb 1972 [3 March 1971] 9113/72 Heading B3M A belt sheave or similar article is made by forcing a pair of opposed rollers 10, Fig. 1, against a disc-like blank 12, the rollers progressively forming a groove in the blank, Fig. 3. The shape of the blank is defined by the rollers and a pair of chucks 19 and 20 which support the blank. Lateral recesses may be provided in either the chucks or rollers (Figs. 4, 5, not shown) to accommodate excess material during rolling. The rollers 10, Fig. 6, are driven in the same sense, whereas the blank is freely rotatable. The rollers are supported in slides 105 and 106 which are urged towards and away from the blank by arms 119 and 120. The arms are pivoted at 121 and 122 and are shifted by respective rams 115 and 116 carried on a shaft 109. The shaft is oscillated by a hydraulically operated rack and pinion mechanism (Fig. 7, not shown). The working stroke of the rollers 10 can be adjusted by shims 130, 140 and nuts 141, 142 associated with the two slides. The chucks 19 and 20, Fig. 10, are urged together by a spring 193 and are movable axially on a spindle 192 by means of a pistonrod 205. Movement of the chucks is controlled by stops and micro-switches, the machine being automatically switched off in the event of a malfunction. The operation of the rack and pinion mechanism is also controlled by microswitches in response to the angular displacement of the shaft 109. (For Figures see next column.)

Title: Improvements in and relating to radio-frequency oscillators
Inventor: RATCLIFFE STANLEY
IPC: H03B5/18
Filed: 1947-04-03
Abstract: 641,892. Automatic frequency control. MINISTER OF SUPPLY. April 3, 1947, No. 9132. [Class 38 (iv)] [Also in Group XL (c)] A reflector klystron or like oscillation generator is automatically controlled in frequency by distorting its resonator in accordance with a control voltage, and at the same time using the control voltage to adjust the bias on the reflector electrode to an optimum value for the new frequency. The resonator distortion may be effected by tuning-struts controlled by the heat developed in the anode of a control valve, the grid of which is fed with widthmodulated square-wave pulses, whose modulation represents the tuning error in sense and magnitude. This control voltage is also applied at 12, Fig. 1, through a resistor 15 to the grid of a valve 13 which has an anode resistor 14 and a feed-back connection comprising resistor 16 and condenser 17 between anode and grid. The klystron 3 has its reflector electrode 7 connected to a voltage-divider 9, 10 across the supply, and the output voltage of the valve 13 is applied through a resistor 18 to vary the reflector bias, so that with changes of frequency produced by the resonator distortion, the klystron will operate efficiently and without danger of cessation of oscillation. The variation of anode voltage of the valve 13 follows an exponential law, the time constant of which is dependent on the time constant of the elements 16, 17 and is made equal to the thermal time constant of the resonator. If the thermal time constants of heating and cooling are different, the circuit of Fig. 2 is employed, in which an additional cathode-follower valve 19 has its grid connected directly to the grid of the valve 13. When the grids become more positive, the circuit operates as in Fig. 1, but when the grids become more negative the diode valve 23 is conductive and connects an additional condenser 24 in parallel with the condenser 17 and gives a larger time constant. Specification 641,889 is referred to.

Filed: 1957-03-20
Abstract: 821,365. Recording-apparatus; counting- apparatus. LANDIS & GYR A.G. March 20, 1957 [March 21, 1956], No. 9153/57. Classes 106 (1) and 106 (4). [Also in Group XX] A meter 2 has at least one indicating- drum 3 carrying radioactive symbols 13 so that its reading may be recorded on a photographic foil 14. A dial plate 4 with reading apertures is spaced from a protective plate 10, which is pervious to light and radiation, to form a guide channel into which a strip 15 carrying the foil 14 is inserted long enough to be influenced by radiations from the symbols 13 in register with the apertures 5, the foil being masked by a strip 16 impervious to light, but pervious to the radiations. The foil is later removed from the strip 15, developed and printed. The foil carrier may be a long narrow card or it may be postcard size, perforated along its longer line of symmetry to facilitate folding for insertion in a narrow guide channel. To ensure a uniform exposure time three guide channels may be provided, one registering with the reading apertures, the others parallel thereto, one above and one below, separated by spring-urged shutters controlled through a lever by an electromagnet, which is energized periodically twice in succession. An exposed foil can be removed from the lower channel and a new one inserted in the upper channel any time between recordings. Each time the electromagnet is energized the lower shutter opens and closes and then the upper shutter opens and closes. This ensures that the centre channel is unloaded before being reloaded and that exposure takes place until the next energization, whereupon the exposed foil drops to the bottom channel ready to be extracted.
