Abstract: 26,836. Foster, J. Dec. 5. Evaporating brine &c.-Relates to multiple-effect apparatus of the vertical type, Fig. 1 shows a sectional elevation, and Fig. 2 a sectional plan, of an evaporating-vessel, and Fig. 3 a side view of a partition plate. The heating-vessel or calandria A<1> of each evaparator A is made in two or more sections, which, when bolted together at A', leave a space B to cause a partial repose of the liquid under treatment. The heating-tubes a, a<4> increase in diameter towards the centre, so that the liquid is caused to circulate in the direction indicated by arrows in Fig. 1. The crystals, formed as the liquid cools in flowing down the larger tubes a' &c. fall to the bottom of the part B', which is provided with a cooling-jacket B'. When the part B' is made in two parts united along the line X, the slotted partitions b<1> are made parallel ; otherwise they are inclined as shown. As an alternative, the repose space B may be extended downwards, preferably in conical form. A jacketed space C, with strengthening-ribs a<3>, may be made on each side of the repose space B, for the circulation of cold air, supplied and discharged through the pipes C', C', respectively. The pipe C<2> may be connected to the jacket B<2>. The liquid to be evaporated can be used as the cooling- medium, and is thus preliminarily heated. The steam &c. for heating is introduced through the parts D into each half of the calandria, as described in Specification No. 3118, A.D. 1895.

Title: Improvements relating to Apparatus for Dyeing, Bleaching Degreasing and Mercerising Textile Materials
Inventor: NAEYER THEODORE DE
Filed: 1903-09-30
Granted: 1904-09-30
Abstract: 20,959. Naeyer, T. de. Dec. 31, A.D. 1902, [date appliedfor under Patents Act, A.D. 1901]. Yarns and threads, mercerizing. - I n apparatus for dyeing textile materials in the raw state or as threads or fabrics and for mercerizing cotton in any state, the bath is heated without possibility of dilution in a steam-jacketed boiler A, Figs. 1 and 2, which is connected by distributing-pipes and a pump C to a battery of vats B. These vats are preferably of trapezoidal or conical form to allow layers of textile materials of smaller area to be placed nearer the bath outlet than the inlet, and to facilitate the arrangement of bobbins of slivers &c. in a quincunx manner. The boiler cover E, in addition to the central charging-aperture F, has a second opening G connected through a valve T, with the discharge pipes S of the vats B. The pump C is connected on the inlet side through a pipe W to the outlet I of the boiler, and, on the other side, through a pipe Y to the inlets R of the vats B. Various accessories, such as liquid-level gauges, safety-valves, &c., are provided where necessary. The inlets and outlets of the vats B are covered with perforated plates b, c. The inlets are preferably larger than the outlets to produce the desired pressure in the bath, or, as shown, the outlets may be fitted with a weighted valve T, which is prevented from closing entirely by a set-screw placed underneath and opens under a predetermined pressure to restrict the discharge from the vats. If desired, the pressure of the bath in the vats may be produced by a column of liquid instead of by a pump ; the weighted valve T may also be replaced by a hand-operated cock.
Patent GB-190321887-A (GB)
Title: Improvements in Binocular Telemeters.
Inventor: PULFRICH CARL
Filed: 1903-10-12
Granted: 1904-09-22
Abstract: 21,887. Pulfrich, C., and K÷nig, A. Oct. 12. Range-finders.-Relates to a stereoscopic range-finder, based upon the fact that when a binocular telescope, in afocal adjustment, is employed for the observation of an object at a finite distance, the apparent distance of the image seen depends upon the total stereoscopic power of the instrument. This total stereoscopic power, again, is equal to the product of the magnifying power and the specific stereoscopic power, which latter quantity is obtained by dividing the interobjective distance by the interocular distance. When, then, two binoculars, with different total stereoscopic powers, are employed for the simultaneous observation of a distant object by a single observer, he sees two images at apparently different distances, and the difference between these apparent distances depends upon the distance of the object. In the range-finder described, this difference of the apparent distances is measured, and thus the distance of the object determined. Fig. 8 shows a simple form. Total-reflecting prisms g, h are mounted at the ends of a tube as shown. These reflect light on to half-silvered reflecting-surfaces i, k, mounted in front of the objectives a of a telescope of the Galilean type. The surfaces i, k are formed in rectangular glass blocks which allow of the direct passage of light, without reflection, to the telescope. The arrangement shown thus forms virtually two binocular telescopes, each with the same magnifying power and interocular distance, but with different interobjective distances. In one case, this distance is equal to the distance between the lenses a, while in the other it is equal to the distance between the reflectors g, h. The adjustment for equalizing the apparent distances of the two images is effected by rotating the prism h by a micrometer screw o. Several other modifications are shown diagrammatically, in some of which the difference between the total stereoscopic powers of the two telescopes is increased, to increase the sensitiveness of the instrument, by giving negative values to the magnifying and stereoscopic powers. In some forms, the two images are observed in rapid succession and not simultaneously.

Title: An Improved Process for Drying and otherwise Treating Materials by Air or other Currents
Inventor: TRUMP EDWARD NEEDLES
Filed: 1903-12-29
Granted: 1904-12-08
Abstract: 28,594. Lake, H. H., [Trump, E. N.]. Dec. 29. Solids, treating with gases; alkaline bicarbonates. -Relates to a process for the removal or addition of moisture, gases, or liquids from materials, or for other physical or chemical treatment in which the specific gravity of the material is diminished by means of an ascending current of air or other gaseous or liquid agent, which decreases in velocity as it rises, and may also have a rotating as well as a vertical motion, in a vertical stack or pipe of inverted conical form into which the material is supplied either at the top or only slightly above the air &c. inlet. The blower 2, Fig. 1, for introducing the air &c. and for producing the upward current is driven by an electric motor and connected directly or tangentially to the bottom of the stack to produce the require motion of the air &c. The material to be treated falls through a shoot 12 into a casing 3 provided with a rotating bottom and a deflecting blade which co-operate to deflect the material through a side inlet into the stack 1. The blade is adjustable by means of an external lever handle to vary the feed. The material is kept heaped up over the blade by a horizontal shield above it to seal the inlet against the escape of air &c. The raw material passing up with the finished product and the air &c. current is separated and thrown back by adjustable baffles 15<a> on a stem 16, whereas the finished product passes over through the outlet 17 to a separator 18 of the cyclone separator type. The air &c. current passes over from the separator 18 to a dust separator 21 and thence through a heater 24 back to the blower 2. Conveyers 19, 22 carry off the finished product and dust from the separators 18, 21. Spent air &c. may be allowed to escape through a pipe 26 from the separator 21, and fresh air &c. supplied through a pipe 27. A receptacle 29 or door at the bottom of the stack 1 allows of the withdrawal of material which may have fallen below the air &c. inlet. In the application of the apparatus for drying finely-divided moist material, the raw material is raised and held at a certain point by the air current, and is raised above this point only as it becomes drier and of less density. The material may be fed in at the top of the stack 1 by a screw or screws 33, 34, Figs. 8 and 9, surrounded by baffles 30, 31, 32 which ensure the separation of the raw as well as of the partiallyfinished material from the finished product. In addition to the air or other suspending-agent, other agents which have special functions to perform on the material may be introduced into the system at any desired point; for example carbonic acid may be introduced to convert a monocarbonate of soda into a bicarbonate.

After standing, the acid is neutralized with alkalies and the product is separated and boiled with a dilute solution of sodium carbonate, ionone being formed.
Patent GB-190424604-A (GB)
Title: Improvements in, or relating to Power Factor Indicators
Inventor: SUMPNER WILLIAM EDWARD
Filed: 1904-11-14
Granted: 1905-09-21
Abstract: 24,604. Sumpner, W. E. Nov. 14. Testing.-A power-factor indicator is operated by the interaction of a rotating and an alternating magnetic field, one depending on the voltages and the other on the currents in the circuit to be tested. A coil carrying the current producing the alternating field rotates freely in the narrow air gap of a stationary inductor wound with at least two sets of coils to produce a rotating field. The inductor A, Fig. 2, may be built up of slotted rings and discs, and the windings may be confined to the outer member. The windings may be arranged for either the voltages or currents, and may be connected directly or through transformers. For three-phase circuits, the winding may be in three parts, arranged symmetrically or otherwise according to the nature of the scale required. The moving coil E is balanced and uncontrolled, unless the instrument is to read zero when not in use, in which case a very weak control may be added. Current is conveyed through the fine wires E'. Two or more moving coils may be fixed at an angle to each other, and supplied with the same or with different currents, the relative phases of which may be changed for use with two separate scales. The coil may be pivoted with one side in the centre to obtain a larger range of movement, and coils and inductors of other shapes may be employed. The coil may be damped. For a three-phase circuit, the moving coil may be connected in series with a non-inductive resistance and the secondaries of two potential or current transformers. A switch may be placed in the circuit to reverse the connection of one of the secondaries, to make possible the use of two scales, one for high and the other for low power-factors. The same result may be obtained by substituting a condenser for the resistance in series with the moving coil. For a single-phase circuit, the instrument may be connected as indicated in Fig. 4. The inductor windings C, C<1> are connected through a non-inductive resistance R' and a choking-coil S to the two secondaries P<2> of the single primary coil P<1>. A single divided secondary may be used, or the secondaries of two distinct primaries may be similarly connected. The moving coil E and non- inductive resistance M are connected across the mains. According to the Provisional Specification, the holes or slots in the inductor are preferably inclined to the axis.
