Abstract: 24,245. Laycock, W. S. Nov. 29. Indicators, stopping-place and route, for vehicles. -Relates to destination and stopping-place indi- cators for tramcars. The indicator is mounted in a casing A fixed in a prominent position on the car. The casing has a sight aperture G, which may be glazed, and is provided with electric or other lamps L, for illuminating the indicator at night. The names of the stopping-places and destinations are arranged in succession on a strip of fabric, which is attached to two rollers R, R<2>, so that it may be wound from one on to the other. The names are preferably semi-transparent on an opaque ground, and may be white or coloured. Each roller is fitted with a friction brake of the kind described in Specification No. 16,378, A.D. 1896, [Abridgment Class Furniture &c.], in which, as shown in Fig. 4, a leather disc J on the frame E attached to the roller is frictionally engaged by the collar C on the spring-controlled spindle S, the pawl and ratchet P, D on the end of the spindle permitting the free movement of the roller in one direction. The brakes of the two rollers act in opposite directions, to put the necessary tension on the strip in both directions of its movement. The rotation of the rollers may be effected directly by a handle H, or through bevel gearing &c. In a modification, only one roller is provided with a brake, the other being fitted with a spring, which winds up the band when the braked roller is turned in the direction to permit such movement.

Abstract: 9045. Barby, H. April 18. Shutters.-Relates to a rollerblind shutter with mechanism for altering the width of the exposure slit. Fig. 14 shows the general arrangement by which the width of the slit is adjusted. The two sections b, b<1> of the blind are connected by cords f, f<3> and pulleys f<1>, f<4> in such a way that, when the end sections d, d<1> of the roller rotate relatively to the middle section a, the cords f, f<3> are lengthened or shortened, and the slit or distance between band b<1> is increased or diminished.

Title: Improvements in Engine Governors.
Inventor: REID WILLIAM
Filed: 1902-08-23
Granted: 1903-07-02
Abstract: 18,544. Reid, W. Aug. 23. Stop gear.-A device adapted for stopping a steam engine when the governor-driving belt is accidentally disconnected is shown in Figs. 1 and 2. The driving-belt c normally supports a roller C carried by a bell-crank lever B, which has an arm b adapted to slide the bar A from under the governor F, and which has a curved arm r<3> adapted to brake the governor pulley G. If the driving-belt becomes disconnected, the roller falls and the bar is withdrawn, so that the governor sleeve a falls and strikes a bell-crank lever d, which actuates a trip lever e on the stop-valve spindle n, so as to close the valve. When the governor is used on a traction engine, a stop m, locks the sliding bar, and puts the apparatus out of action.

Title: Improvements in or pertaining to Catalysis.
Inventor: HOELBLING VICTOR
Filed: 1902-11-05
Granted: 1903-10-08
Abstract: 24,256. H÷lbling, V., and Ditz, H. Nov. 5. Sulphuric anhydride.-Relates to a contact agent for use in manufacturing sulphuric anhydride from gaseous mixtures containing sulphurous-acid gas and oxygen. The mixture of oxalates or other compounds of the rare earths cerium, lanthanum, neodymium, praseodymium, yttrium, thorium, &c., resulting from the manufacture of thorium compounds, is treated either directly, or after calcining, with sulphuric acid, and the resulting mixture of sulphates is heated to a low red heat, from 300‹-600‹ C. The porous mass is broken up and used directly, or else some substance such as asbestos, baked clay, &c. is impregnated with a solution of the above sulphate mixture, or with a solution of cerium, lanthanum, didymium, neodymium, praseodymium, yttrium, thorium, or the like sulphate, either separately or together in any desired proportions, and heated to the requisite temperature as above. The catalytic agent is regenerated by heating with a little sulphuric acid, or else by dissolving and precipitating the absorbed impurities, and then evaporating and heating the residue as above. The yield of sulphuric anhydride is nearly that theoretically obtainable, even with mixtures poor in sulphur dioxide, while the yield is not diminished when gases rich in arsenic are used, the arsenic compounds being absorbed by the mixture of sulphates.

Granted: 1903-03-05
Abstract: 25,931. Barham, C. J., Bulbeck, H. C., and Baillie, C. Innes-. Nov. 25. Kilns.-In kilns for drying and burning bricks, longitudinal, tunnel-like, drying-chambers a, in superposed rows, are arranged between two rows of transversely-placed firing-chambers b, as shown in the sectional plan view, Fig. 1, and the partial transverse section, Fig. 4. Fig. 2 shows some of the firing-chambers in sectional elevation. The waste gases from the firing-chambers are first passed through zig-zag and other flues in the side walls, floor, and roof of the drying-chambers, and finally into the chambers themselves at one end, traversing the chambers in a direction opposite to that of the bricks, which are run through the chambers on trucks. The firing-chambers have connecting.flues b<3>, and benches b<4> on which the dried bricks are loosely built, fuel being fed to the spaces between the benches through end doors.

Patent GB-190312677-A (GB)
Title: Improvements in Photographic Printing Apparatus.
Inventor: INTIRE HERVEY HEMAN MC
Filed: 1903-06-05
Granted: 1903-07-09
Abstract: 12,677. McIntire, H. H. June 5. Printing. - Relates to apparatus for rapidly printing photographs on cut sheets of sensitized paper. The paper 9 is introduced at the opening 2 in the casing 1. It is held in contact with the negatives 6, which are fixed to the sides of a platen 4, by an endless band 7 engaging with one half of the perimeter of the platen. The printed photographs are discharged into the drawer 3. The platen 4 revolves on hollow axles 5 and is driven by a suitable motor 26. Fixed to the axles 5 and within the platen 4 is a stationary drum 10 containing a series of incandescent electric lights, the conducting wires of which pass through the hollow axles. The drum has an opening, normally closed by a shutter 13, which consists of a semi-cylindrical shell revolving on the axles 5. A removable trip arm 16 having a bifurcated end 22 is mounted in the platen and may be placed in one of a number of keyhole slots in the block 20. Opposite each of these slots is a resilient wire 23 attached to the stationary portion of the drum extending round the shutter 13, each wire having its free end bent forming a stop 24 to engage with the shoulder 25 on the shutter. The wires 23 are of different lengths, so that the time during which each negative is exposed to the light may be varied. As the platen revolves, the trip arm opens the shutter by engaging its edge, while the forked ends 22 engage one of the wires 23, and depress it fobbing the stop in the path of the shoulder 25 on the shutter. In this position, the light is emitted to print the photograph. When the trip arm reaches the shoulder 25, the shutter is released and is closed by the weight 15. By varying the number of sides of the platen, any desired number of prints may be produced at one revolution.

Granted: 1904-02-04
Abstract: 16,965. Robertson, J. P. Aug. 4. Signals, a u t o - matic - alarm; signals, indicator or visible.-Relates to the electric firealarm and telephone system described in Specification No. 18,148, A.D. 1902, [Abridgment Class Fire, Extinction &c. of], in which beat-operated devices close the circuit of an electromagnetic switch controlling a graphophone and the ringing and speaking circuits. Each thermostat consists of a metallic vessel 50, Fig. 8, having a buckled base and a corrugated head. Expansive fluid or air is supplied by a connection 55, and its level indicated by a gauge glass 51, and its pressure by a pointer 58 connected to a weighted lever bearing on a lug on the head. If the temperature increases, the base expands and closes the circuit K, P of the indicator lamps. If the pressure falls by leakage in the pipe system or vessel 50, the head collapses and the lever 60 falls over on the coutact 61, thus completing the circuit N, 0 of an indicator coil 26, Fig. 3, the excitation of which raises a pin 72 and drops an indicator 86.
