Abstract: 174,619. Hinterdorfer, r., and R¾na, J. Dec. 27, 1913, [Convention date]. Ruling machines and appliances. - In ruling- machines the parts of the sheet to be left unruled are covered up by means of one or more strips of adjustable width which are revolved in a circle. The invention is applied to a machine in which sheets fed in at 3, Fig. 2, are carried by a travelling band 1 and cords 2 between a ruling- roll 6, or pens, and a roller 7 and are finally delivered at 5. The shaft 13 of the roll 6 is mounted in slots 12 in supports 11 loosely mounted on a hollow shaft 19, Fig. 1, and is carried by rock arms 14 spring-pressed against a screw stop 17. The roll 6 is inked by a roller 8 supplied from a well 10 by a suction cloth 9. The parts of the sheet to be left unruled are covered by strips 29 having straight or curved edges or fitted with stencils. These strips are fixed to dove-tail blocks 28 carried in grooves 27 in discs 26, one of which is keyed to the shaft 19, the other being loosely mounted thereon and adjustable to tension the strips by a nut 30. As shown in Fig. 5, each strip may be in two parts 29, 29a separately adjustable, whereby the effective width may be varied. The shaft 19 has a flange 21 adjustably secured by bolts 23 to the flange 20 of a main driving shaft 18, a pointer on the latter flange and a scale on the former indicating the adjustment. In order to prevent the supports 11 from rotating and yet allow the strips 29 to pass, a member 35 is provided, vertically slidable in guides 36 and raised against the action of a spring by a cam 38 engaging a roller 39. Hooked ends 34 are also provided on the member 35 engaging in turn slots 33 in the top and bottom respectively of one of the discs 11. Set-off rollers 53, 54, Fig. 2, are provided for absorbing the ink collecting on the strips 29. A comb 45, Fig. 2, is raised periodically, to allow a sheet to pass, by a projection 51 on one of the discs 26 engaging the end 50 of a bell crank 49 connected to a slotted member 46 carrying the comb, a spring returning the latter, and a stop 52 limiting the swing of the lever 49. Pens clamped between jaws, one of which is fixed to the lever 14, may be used in place of the roll 6.

Title: Improvements relating to mechanism for controlling moving leaves or moving band apparatus
IPC: G04B19/20
Filed: 1925-01-27
Abstract: 238,843. Soc. Anon. des Ateliers BrilliÚ FrÞres. Aug. 23, 1924, [Convention date]. Electric clocks; dials.-An electric master clock 20 of which the minute spindle 21 is driven intermitently one step each minute controls a secondary clock 1 having minute and hour leaves 4, 5, 6 mounted on the minute spindle 2 and the hour spindle. The minute spindle 2 is driven by gea.ring 9, 10 and an electric motor 8 and also carries a small cam 13 operating linkage 14, 15, 18, pawl 19, and thereby a ratchet 11 on the hour spindle. The minute spindles 2, 21 of the secondary and master clocks, Fig. 3 carry bevel wheels 22, 23 of a differential gear, the planet wheels 24, 25 being carried on a planet carrier 26 which also carries a pin 27 which normally maintains raised a block 28 and contacts 29. Contacts 29 and 30 when closed complete the circuit through the motor 8. When at the end of a minute arbor 21 rotates, wheel 22 remains stationary, planet carrier 26 rotates, pin 27 moves from under block 28, contacts 29, 30 close and motor 8 drives spindle 2 sufficiently for one minute leaf to drop. At the same time wheel 22 drives the planet carrier back until the pin 27 is again under block 28, opening contacts 29, 30 and stopping the motor. Should the source of current to the motor 8 fail the planet carrier 26 continues to rotate until the current is restored whereupon motor 8 drives the spindle 2 until the pin 27 raises the block 28 and breaks contacts 29 and 30, during which time the necessary number of minute leaves will have dropped to place the secondary and master clocks in agreement. In case the current fails for longer than one rotation of the planet carrier a gear 32, pin 33 thereon and contacts 34, 35 are provided, it being necessary to open both sets of contacts 29, 30 and 34, 35 to stop the motor 8. Instead of pivoted leaves, moving bands or drums may be used and instead of one or more clocks the master control apparatus may control secondary advertising devices. The rear faces of the leaves may bear advertising matter.

Title: Process for the manufacture of highly polymerized viscose rayon
IPC: D01F2/08
Filed: 1958-01-24
Abstract: Filaments of regenerated cellulose rayon having a high degree of polymerization are produced by xanthating alkali cellulose with a mixture of carbon disulphide and a surface-active agent in the presence of a monoamine, dissolving the resulting cellulose xanthate in dilute aqueous alkali, extruding the resulting viscose into a spinning bath containing up to 20 grams per litre of sulphuric acid or up to 50 grams per litre of oxalic acid, or containing a mixture of up to 15 grams per litre of sulphuric acid and up to 30 grams per litre of oxalic acid, but containing no zinc sulphate, care being taken to ensure that the content of sodium ions which accumulate in the bath during the spinning process does not exceed 20 grams per litre, and then immersing the filaments formed in the spinning bath in a secondary bath containing not more than 15 grams per litre of sulphuric acid. Suitable monoamines are those having the general formula: R1R2R3N in which at least one of R1, R2 and R3 is an alkyl radical and the remainder are H atoms, e.g. triethylamine, and suitable surface active agents are turkey-red oil and polyoxyethylene alkylamino ethers in which the alkyl group has 6-10 carbon atoms. The weight of amine used may be 0,5%-4,0% by weight based on the weight of the starting material, e.g. wood pulp.  The viscose preferably has a viscosity of more than 200 sec. (as measured by the ball-drop method).  The filaments may be stretched in the spinning bath on a stepped godet and are then passed through the secondary bath, which may be maintained at an elevated temperature, either under tension or without tension.  Specifications 652,746, 654,083 and 730,226 are referred to.

Title: Reflex-reflecting particles
IPC: G02B5/128
Filed: 1963-01-21
Abstract: Surfaces are made reflex-reflective by applying or bonding thereto particles, each particle comprising a core consisting of glass-like inorganic material or formed of a nucleus of metal or lithic rock material with an outer layer of glass-like inorganic material, into which core is partially embedded a plurality of glass microspheres, each coated with a hemispherical specular-reflecting metal such as silver, the coating lying between the glass microsphere and the core. The particles may be mixed with glass beads.  The particles are 100 microns to 1/2 inch in diameter.  The glass-like material may be a coating of inorganic enamel.  The particles may be coated with a fluorocarbon solution, causing them to float, for example in paint on a road surface.  The softening temperature of the glass-like material is at least 100 DEG  C. below that of the glass of the microspheres, and the thermal coefficient of expansion of the glass-like material is at least or up to 100% more than that of the glass of the microspheres, and the refractive index of the latter is 1.7-2.7.  In producing the particles, the microspheres are coated with metal in a stainless steel mixing vessel, and the unwanted metal is removed by etching with sulphuric acid or potassium dichromate.  The core, with a thin temporary coating of a thermosetting organic resin, is mixed while heating with the coated microspheres and takes up a mono-layer of the latter.  The particles are then mixed with up to three times their volume of inorganic spacing elements, which may also be reflex-reflecting silver-coated glass hemispheres treated with needle-like colloidal alumina as a film-forming material, agitated and heated rapidly to soften the core surface and draw in the microspheres up to half their diameter, while burning off the resin coating.  Glass compositions referred to are in per cent by weight: (1) Na2O, 19.28; K2O, 10.15; Li2O, 3.7; CaO 6.06; B2O3, 5.36; P2O5, 3.94; MnO2, 0.26; TiO2, 17.96; SiO2, 33.29 for the glass core and (2) TiO2, 43.5; BaO, 29.3; SiO2, 14.3; Na2O, 8.38; B2O3, 3.06; K2O, 1.44 for the glass microspheres.

Filed: 1946-01-29
Abstract: 607,174. Frequency modulation. TILLMAN, J. R. Jan. 29, 1946, No. 2800. [Class 40 (v)] A discriminator circuit comprises a Wien bridge or equivalent network embodying only resistances and condensers, arranged to operate over the portion of its output-voltage/ frequency characteristic near its balancefrequency, and one or more correction networks to improve the linearity of the overall voltage output/frequency characteristic. A modified Wien bridge network, Fig. 1, has one pair of opposite arms composed of series connected resistances R2, R3 and condensers C2, C3, and the other pair of opposite arms composed of parallel resistances R1, R4 and condensers C1, C4. The similar components of opposite arms are preferably equal. The resistances R1, R4 or condensers C1, C4 may be made variable to adjust the balance frequency, which is at or beyond one or other of the limits of the frequency modulated input. Preferably two such networks B1, B2 are used in parallel, Fig. 3, and their outputs fed through correction networks CN1, CN2 to separate amplifier rectifiers AR1, AR2, the gain of one of which is adjustable. The rectified outputs are combined in opposition. The balance frequencies of networks B1, B2 are arranged to be on opposite sides of the centre frequency of the signal. A band-pass filter BPF is provided in the primary circuit of the input transformer T1. The correcting networks CN1, CN2 composed of series condensers Cs and shunt resistances Rp, may be replaced by one correction network in the primary circuit of the input transformer, Fig. 7 (not shown), or by a correction network in the output of one bridge network and a potentiometer resistance to reduce the output applied to the rectifier from the other bridge network, Fig. 6 (not shown). If the networks B1, B2, Fig. 8, are of the type having an input terminal commoned, they may be connected in parallel directly across the signal source, and a correction network employing a series resistance Rs and shunt inductance Lp inserted in the common input circuit. The bridge networks may be fed from a high impedance source such as a pentode valve, in which case an inductance in the anode circuit forms a correction network. The temperature coefficients of the resistances and condensers of each bridge network should be selected to cancel each other.
