Title: Improvements in chiming and striking mechanisms for clocks
IPC: G04B21/02
Filed: 1921-09-12
Abstract: 172,605. Bõuerle, M. [Firm of]. Dec. 6, 1920, [Convention date]. No Patent granted. (Sealing fee not paid). Chimes; striking-mechanism.-In quarter-hour-chiming and hour-striking mechanism, automatic regulation is effected so that, even if disturbances have occurred, the chime corresponding to the first quarter is always produced whereupon at the succeeding quarters and at the full hour the chimes and striking are executed in proper succession. As shown in Fig. 1, the minute hand 80 is approaching the first quarter and a finger of the wheel oscillates a lever 45 lifting a lever 41 which in turn lifts a lever 40, so releasing the rack 38 which is urged to the left by the spring 48 a distance of one tooth corresponding to the first step on the pin wheel 12. At exactly the quarter, the finger on the wheel 47 rides from under the lever 45 and allows the lever 40 to drop and also releases the pin 43 on the wheel 22. Meanwhile the lever 66 is raised by the pin 65 on the wheel 8 and so by means of the lever 68 lifts the drive-lever 55, Fig. 3. The upper arm 56 of this lever has a claw 57 which is lifted out of a notch 58 in a drum 59 and the lower arm 60 lifts an intermediary wheel 53 into engagement with two wheels 51, 52, one of which 51 is fast on the cam disc shaft and the other 52 rides loosely thereon but is always engaged with the toothed wheel 35 of the chime drum 30. The cam disc 39 raises the lever 40 by means of the pin 74 and moves the rack by means of the pin 73, meanwhile driving the chime drum 30 by means of the wheels 51, 52, 53, and so chiming the first quarter. The arm 26, Fig. 4, of the hour-striking lever is moved out of the path of the pins on the hour-striking wheel 14 by means of the two-armed lever 61, 62 operated by raising the drive-lever 55, i.e. while the chime drum is in gear with the wheels 51, 52, 53 the hour-striking gear is out of action. At the succeeding quarters similar action takes place, but immediately after the third quarter has chimed the claw 57 falls into the notch 58 causing the chime drum to be put out of action and the arm 26 of the striking lever to be moved into the path of the pins of the hourstriking wheel 14 which is operated at the hour. If a disturbance is caused due, say, to a rapid adjustment of the hands so that one of the quarters is missed, the next quarter chimes correctly but at the full hour the drum 59 not having completed its revolution to allow the claw 57 to fall into the notch 58 the chimes due to the quarter missed are executed and thereafter the hour is immediately struck the appropriate number of strokes less the number of chimes already executed, but at the succeeding quarter the chimes are executed properly.

Abstract: 358,652. Jacquards. DEVOGE & CO., Ltd. and FIELDING, P. P., Sycamore Street, Oldham Road, Manchester. Aug. 16, 1930, No. 24564. [Classes 142 (i) a,nd 142 (iv).] To obtain with the aid of fewer cards than usual different weaves in the figures of damasks, furnishing fabrics, &c., a double-lift single cylinder jacquard is used wherein the hooks a are normally out of the path of the knives x, z of the griffes X, Z, and are pushed into the path thereof by needles f, each controlling several hooks, whilst some of the hooks are' controlled by more than one needle. To allow for this, the needles have long eyes f<2> as well as short eyes f<1> for operating the hooks, and they are moved by blanks on the cards on the cylinder G into contact with a spring box H whereby the needles are returned to normal position. The hooks that are operated by long eyes in the needles are returned to normal position by dummy needles h provided with small eyes h<1> and not acted upon by the cards. Spring hooks may be used. The hooks are connected in pairs A, B, C, D by cords &c. b to pairs of neck cords c each connected to one or more harness ends d, and mails m. The warp threads may be threaded through these in the order shown. In addition to the hook-controlling needles f and the dummy needles h, additional rows of needles f<11> are used for operating strong hooks controlling shafts e passing through the necks c and serving to lift whole rows of these. These needles f<11> may be controlled by the same cords as the needles or by different ones. An example is described detailing the cutting of the cards and the lifting of the hooks for various weaves wherein the shafts are lifted in an order which gives a weft satin weave. If in addition at any pick with the griff Z lifting for example the card is blank opposite needle No. 8, and cut opposite needle No. 2, a warp twill effect results. If the card is cut opposite No. 1, and blank opposite No. 2 needle, a warp satin results, if blank opposite both needles all the warp is lifted. In designing the figure on the point paper employed, each weave effect is painted solid in a different colour.

Abstract: The resistance to ultra-violet light of a shaped article of an organic polymeric material, especially a film, is enhanced by incorporating to a limited depth therein an ultra-violet light absorbent compound compatible therewith and of lower melting point, by a method comprising applying the compound to at least one surface of the article, heating the article to a temperature between the melting points of the compound and the polymeric material until the compound has penetrated the article and removing any residual compound which has not penetrated the article.  Preferably, the compound is applied to the surface in an amount of at least about 0,4 gms. per sq. metre and penetrates to a depth of not more than about 20% of the cross-section of the article.  In a preferred method, a film of thickness at least 0,5 mil is treated so that the compound penetrates not more than about 0,1 mil from the surface or surfaces so treated.  Suitable compounds include p-aminobenzoato chromic chloride, phenyl salicylate and resorcinol, but the preferred compounds are benzophenone derivatives of the formula: <FORM:0872421/IV (a)/1> where X1, X2, and X3 each represent a hydrogen or halogen atom or a hydroxy, alkyl or alkoxy group.  A long list of such compounds is given, of which 2, 21-dihydroxy-4, 41-dimethoxy benzophenone, 2, 21, 4, 41-tetrahydroxybenzophenone, and a mixture of these, are especially preferred.  Specified film materials include regenerated cellulose, hydroxyethyl cellulose, carboxy methyl cellulose, ethyl cellulose, cellulose acetate and cellulose nitrate, amylose, polyoxymethylene, polyethylene, polyvinyl chloride, polyvinyl fluoride, and polyethylene terephthalate.  The ultra-violet light absorbent compound can be applied from solution or dispersion, as a solid powder, or as a liquid melt, before, during, or after biaxial orientation and heat-setting.  When one of the benzophenone derivatives is applied, the article may then be heated at from 115 DEG -200 DEG C. for at least 15 secs.  When a film is treated with the specified mixture of benzophenone derivatives, it may then be heated at from 115 DEG -200 DEG C. for at least 2 mins. In a preferred method a polyethylene terephthalate film is elongated in at least one direction at least twice its original dimensions to a thickness of at least 0,5 mil and heated at 150 DEG -250 DEG C. while restricting dimensional change; at least one surface of the film is then coated with at least 0,4 gms. per sq. metre per surface with one of the benzophenone derivatives, and the coated film is heated at 115 DEG -200 DEG C. for a time sufficient for substantially all of the benzophenone derivative to penetrate the film to a depth of not more than about 0,1 mil from the surface or surfaces coated.
