Patent GB-113409-A (GB)
Title: Improvements relating to Station Indicators.
Inventor: BARRADELL LEONARD
IPC: B61D41/00
Filed: 1917-09-15
Abstract: 113,409. Barradell, L. Sept. 15, 1917. Reel and web apparatus.-A stopping-place indicator for vehicles comprises a band passing from one spring roller to another, and having the desired names or numbers on both sides so that the same indication is simultaneously exhibited through two windows in the casing. Movement of the band is controlled by a hand-operated friction-grip device acting on the band. The band b bearing the desired names or numbers is drawn from a roll d by a roller c operating like a spring blind roller. The band is led over guide rollers e to exhibit the names successively through windows in the ends of a casing a, which may be internally illuminated by a lamp n. Normally, the band is held against movement by a friction grip device comprising a reciprocable member f urged upwards by a spring g to grip the band against the upper part of the casing. When a cable h is pulled on reaching a stopping-place, an oscillating arm l depresses the member f to free the upper portion of the band, and grip the lower portion of the band against the bottom of the casing. At the same time, a transverse bar m draws a length of band from the roller d into a bight. On releasing the cable h, the member f is returned by the spring to grip the upper portion of the band, and the spring-roller c takes up the slack, thus advancing the band to exhibit the succeeding name &c. through the windows.

Filed: 1972-03-21
Abstract: 1345125 Electric watches TIMEX CORP 21 March 1972 [22 March 1971] 13271/72 Heading G3T A regulator 24 has arms 32, 33 with flanges 37, 38 and apertures 39, 41 to receive a hairspring 18 and produces a predetermined positive isochronism characteristic (frequency increasing with amplitude). This is stated to facilitate synchronization with a quartz-crystal controlled oscillator. The arm 32 has a portion 42 in permanent contact with the spring 18 to determine effective spring length, and is also arranged to position the spring centrally in the aperture 41 in the neutral position of a balance Fig.16 (not shown). As oscillation amplitude increases, the spring dwells for an increasing proportion of the time in contact with the sides of aperture 41. The balance (16) carries a maintaining coil (17) and a contact pin (35) which touches a fixed spring (30) to control the coil current.

Title: Method of producing railroad rail sections
IPC: B21B31/14
Filed: 1965-03-30
Abstract: 1,066,328. Rolling. DE WENDELL & CIE. March 30, 1965 [April 15, 1964], No. 13452/65. Heading B3M. A method of producing a rail comprises applying rolling forces in a series of passes to the upper and lower surfaces of the rail head while leaving the side surfaces free (see Fig. 3, not shown), and applying further rolling forces in a series of passes interposed with those of the first series to the side surfaces and the lower surfaces of the rail head while leaving the upper surface free (see Fig. 4, not shown). The blank is maintained symmetrical during the steps as distinct from known methods in which the blank passes through the shapes a, b, c, Fig. 1 (not shown). Fig. 2 (not shown) illustrates the corresponding stages achieved in the present method. The rail is cold-rolled. The base of the rail is formed by a roll 22<SP>1</SP>, Fig. 5 (not shown). Before the blank approaches the series of forming mills it is passed four times through a reversing blanking mill 28, Fig. 21 (not shown), and then through a blank finishing mill 31. The top rolling mills 32 are driven by variable-speed D.C. motors, but the mills 33 are not driven. The final mill 34 rolls the rail to its final shape, Fig. 13 (not shown), and has rolls 35, 36, Fig. 23 (not shown), co-operating with a roll 37. When the rolls are worn, the mill is turned through 180 degrees and other parts of the rolls 35, 36 are used. In a modification, only two mills are used to shape the rail, several passes being made through each of them. The rolls 22, Fig. 26 (not shown), forming the top and under surfaces of the rail, have to be displaced by different amounts during passes to ensure even working of the metal.

Air for the main burner is supplied through a compressor 83 and line 90. Fuel for the pilot burner passes from the pump 70 through a line 92 and a solenoid controlled valve 93. Air for the pilot burner is drawn from the main air supply by a pipe 48. The solenoid valves may be controlled automatically. The main and pilot burners may be withdrawn as a unit with the mounting plate 26. In a modification the main burner may be separately retracted.

Abstract: 1385907 Making catalyst supports; extrusion IMPERIAL CHEMICAL INDUSTRIES Ltd 27 April 1972 [7 May 1971] 13721/71 Heading B5A [Also in Division B1] A catalyst support comprising a multitubular refractory module in which the tube axes are mutually parallel is formed by forcing a plastic composition through a primary zone of a plurality of channels in a solid block and then through an outlet zone of intersecting slots in the same block, the slots being in the form of straight lines and/or continuous curves transverse to the direction of flow of the composition, the aggregate cross-sectional area of the slots being sufficiently less than that of the primary zone channels and the time of passage through the slots being sufficiently long to unify the feed into a module which is dried and calcined to form ceramic bonds. The composition comprises either the material of the support or a compound thermally decomposable or reactable thereto, a liquid and a viscosity-controlling substance soluble in or swellable by the liquid. As shown in Figs. 1, 2, the die comprises a block 10 having circular-section primary zone channels 12 and intersecting slots 14 in the outlet zone. Slots 14 are formed by saw-cutting along mutually perpendicular sets of parallel lines, channels 12 being bored in line with the intersections thereof. The plastic composition may comprise any oxide having the desired refractory properties, e.g. an hydraulic cement and a finely divided aggregate, e.g. low-silica aluminous cements and, as aggregate, alumina, titania, zirconia, mullite or calcined kaolin; clay, refractory spinels &c. are also specified. The catalytic constituent may be a Group VIII metal, e.g. nickel, cobalt or a platinum group metal or metal oxide e.g. for non-oxidative treatment of internal combustion exhaust gases. A ceramic binding agent may be bentonite or another water-swellable clay. A soluble or swellable organic polymer may be starch, a cellulose ether or ester, a polyvinyl alcohol, ester or ether or a protein, the extruded module being calcined to decompose or burn out such polymers.

The transparencies are removably held in position by springs 18, and are brought in sequence parallel to a condenser 8. The rotation is effected by a resistance-controlled motor 27, which through gearing 33, 34, 35 turns a wheel 36 carrying projections 37 which swing an arm 25, 41 against the action of a spring 24. On the outer end of the arm 41 is mounted a spring-pressed pawl 43 which engages behind pins 20 projecting from the carrier 15, and under the influence of the spring 24 forces the carrier forward till the next transparency 19 comes into position. A stop for positioning the carrier 15 comprises two hinged and spring-pressed inclines 48, 49. The pins 20 ride over the incline 48 in one direction, and the incline 49 is depressed by a cam under the arm 41 when this latter is retracted prior to forcing the carrier forward. A shutter 53 mounted on a - crank 54 and moved against a spring 56 by projections 59 on the carrier 15 serves to cut off the light beam during change of picture.
