Title: Method and apparatus for making pressure sensitive labels
Inventor: GRAVES ELIOT DENSLOW
IPC: B31D1/02
Filed: 1951-03-05
Abstract: 697,304. Label-making machines. CONTACT PRODUCTS, Inc. March 5, 1951. No. 5323/51. Class 73. An apparatus for forming pressure-sensitive labels and adhering them to a backing sheet, partially severs a label from a label forming strip before moving it into contact with the backing sheet and then completing the severing. A label forming strip 35 is drawn from a supply roll through a gumming device to gum its upper surface by rolls 32, 33 and is passed over a platen 20 to a laminating device 25 comprising felt-wrapped parallel bars 26, 27 resiliently urged together. A backing strip 58 passes into contact with the strip 35 in the laminating means and is drawn by a conveyer belt 52 round rollers 45, 44. As the label forming strip passes over the platen 20, an oscillating head 10 mounting dies 60a, 60b, 60e. Fig. 11, cooperates therewith to cut the label, a stripper. 70 preventing the strip from adhering to the dies. The feed rollers 32, 33 and belt 52 operate intermittently in timed relation to the head 10. In operation, on the first stroke of the head 10 the dies 60a 60b partially sever a label from the strip 35 but leave a gap 62. The strip 35 is then advanced from X1 to X2, Fig. 11, at which point the leading severed portion L<SP>1</SP> of the label has entered the laminating means 25 and come into contact with the backing strip. On the next stroke of the head 10 the dies 60c complete the severing of the first label while the dies 60a, 60b partially sever the succeeding label. As the combined strips leave the roller 44 the combined labels L and backing strip 58 are separateds from the matrix 35b by being wound onto different rollers. Other shapes of complementary dies for severing the labels are illustrated. The dies are preferably bevelled on their inner edge to force the adhesive away from the edge of the label so that it does not tend to flow over the edge before it is adhered to the backing strip.

Title: A machine for grinding and polishing the edges of watch glasses and the like
IPC: B24B9/08
Filed: 1929-02-18
Abstract: 329,676. Reusser, P. Feb. 18, 1929. Lenses, grinding and polisting; gauges.-In a machine for grinding the edges of watch gases and the like, the work holder is mounted on a vertical spindle which is carried by a slide and is indexed by Geneva mechanism operated throuhh a disengageable worm drive when glasses of polygonal shapes are tc be treated. The frame 1 is provided with a guideway 2 carrying a slide 3 in which is mounted a spindle 18 fitted with a rest 13 for the work piece 44 which is held between upper and lower pads 14. The upper pad may be raised against the pressure of a spring 17 by means of a lever 16 pivoted in an arm 40 secured to the slide. The fixed grinding wheel 5 is driven by a pulley 4 and a pulley 6 on the grinding-spindle drives through a belt 19 a shaft 9 carrying a worm 8 coacting with a worm wheel 12 and mounted at one end in a bearing 10 which can pivot about a vertical axis. The other end of the shaft extends through the arm 40 into a disc 11 which is slotted to coact with a fixed pin 21 so that by partial rotation of the disc the shaft 9 may be swung in a horizontal plane to disengage the worm 8 from its wheel. The wormwheel is mounted on a shaft 32 carrying a wheel 24 which is provided with a pin 25 coacting with a Geneva wheel 23 on the work spindle. For trueing a four-sided watch glass, the Geneva mechanism is arranged to rotate the work through 90‹ for each revolution of the worm wheel 12. By modification of this mechanism other polygonal watch glasses may be ground. In order to withdraw the work from the grinding wheel during the indexing movement, a cam 26 carried by the shaft 32 coacts with a lever 27 which is pivoted to the slide 3 and which in turn coacts with a lever 29 mounted on a fixed pivot 30. The work is held against the grinding wheel by a spring 20 and a screw 15 determines the depth of the cut. When all the edges of the glass have been ground the work movement is automatically stopped. For this purpose the wheel 12 carries one or more pins 39 adapted, at each revolution of the wheel 12, to engage one of a series of pins 38, mounted on a sliding member 37. The arrangement is such that after a predetermined number of revolutions of the wheel 12 (equal to the number of edges on the work) the member 37 is moved into engagement with a pin 47 on the disc 11, thus shifting the disc and moving the worm 8 out of engagement with its wheel. For grinding oval glasses, the Geneva mechanism is released by a wheel 34, Fig. 6, keyed to the shaft 18 and engaging a wheel 35 on the shaft 32. The shaft 18 also carries a templet 33 coacting with a screw 36 so that during the rotation of the work, a reciprocating movement is imparted thereto to obtain a workpiece corresponding with the templet 33. In order to position the work concentrically on the rest a trueing element 41, Fig. 9, slidable on the arm 40 is employed, this element being adjusted by means of a collar 42 in accordance with the size of the work.

Title: Improvements in or relating to the control or regulation of voltage or electric current in electrical systems
IPC: H02P9/22
Filed: 1923-02-24
Abstract: 215,139. British Lighting & Ignition Co., Ltd., and Turner, E. O. Feb. 24, 1923. Regulation, automatic. - A variable speed dynamo a, Fig. 3, having a shunt field f<1> in series with a resistance r of carbon discs held together by spring pressure, is regulated by a winding w<1> of an electromagnet opposing the spring pressure and connected in series with electrolytic cell e. No appreciable current passes through the winding w<1> until the voltage across the dynamo armature exceeds the critical or decomposition voltage of the cells e, whereupon the electromagnet is excited, increasing the value of the resistance r and decreasing the current through the field f<1>. Further regulation may be obtained by placing a reverse field winding f<2> in parallel with the winding w', and still further by placing a series winding w<2> in the output circuit so as tn aid the winding w<1> of the electromagnet. In this latter modification, the winding w<2> operating the resistance r prevents an excessive current passing to an exhausted battery which may be charging from the dynamo even though the voltage across the dynamo may not be above the critical voltage of the cells e and therefore no regulation is being effected by the windings w<1>, f<2>. Fig. 6 shows the cells e applied to the regulation of the excitation of a variable speed dynamo a having a third brush m, to which is connected one end of the main field winding f<1>, the other end thereof being connected to the junction of the cells e and a reverse field winding f<2>. At voltages below the critical voltage of the cells e the excitation is due, to the difference of effect of the windings f<1>, f<2> connected in series between the brush m and one of the main brushes. At voltages above the critical voltage of the cells, currents flows through them, thereby strengthening the reverse field, and weakening the main field by reason of the greater voltage drop across the winding f<2>. Alternatively the winding f<2> may be replaced by a fixed resistance, in which case the only action of the cells is to reduce the current in the winding f<1> due to the enhanced voltage drop across the resistance. As another alternative the winding f<1> is connected directlv between the brush m and one of the main brushes, in which case the cells, when their critical voltage is overcome, allow current to pass through the reverse winding f<2>.

Title: Improvements in speed indicating devices
IPC: G01P3/10
Filed: 1922-02-25
Abstract: 193,281. Bonniksen, B. Feb. 25, 1922. Periodic-counter speed indicators.-A speed indicator of the kind wherein an indicating-device is periodically connected with the driving-means for a definite interval of time under the control of an escapement deriving its maintaining power from the same driving-means, the driving-means also actuating a time-counting device which is controlled by the escapement, has the time-counting device driven through the escapement wheel, being connected thereto by an inelastic driving connection. The dial A is provided with pointers A<3>, A<4> indicating miles per hour on the graduated scale A<2>, a mileage indicator A<5>, the timecounting device A<7> and a trip distance register A<6>. The hands of the time-counting device A<7> are driven through the train of gearing D<2> - - D<4> from the spindle D of the escapement device of a periodic-counter speed indicator of the type described in Specification 2052/12, the gear-wheel D' having a friction grip on the minute spindle E. The units counting-pointer H<6> of the trip distance register A<6> is carried on a spindle H and a tens pointer H<7> may be fitted, friction-driving means being arranged to permit resetting to zero. Zeroizing is accomplished by rotation of a spindle L mounted in a bracket K<3> on the indicator case and carrying a gear-wheel L<3> driving through wheels L<4>, L<5> a wheel L<6> on the shaft H. To permit the time-counter A<7> to be set at zero also by this device a sliding plate J is fitted in the case and carries a gear-wheel J<2> meshing with a wheel H<5> in the trip register train. The plate J may be moved against the pressure of a spring J<4> until the wheel J<2> meshes with an idler wheel G in engagement with the time indicating train; the time-counter may thus be set at zero and, after withdrawing the wheel J<2> from engagement with the wheel G, the trip distance register. To move the plate J, its outer edge is bevelled to engage the similarly bevelled end M<4> of a bar M slidable in guides on the side of the indicator and adapted to be moved by longitudinal movement of the operating spindle L in its sleeve. The dials of the time and the trip indicators may be so graduated that the pointers keep parallel while a desired speed is maintained; in a modified form the two registers are arranged concentrically the pointers being distinguished by colouring or form.

Title: Liquid hydrocarbon composition derived from gaseous olefines and process for the production thereof
IPC: C07C2/18
Filed: 1937-02-25
Abstract: A hydrocarbon mixture of high anti-knock value for use as motor fuel consists of blended liquid polymers or hydrogenated polymers derived from the separate cross-polymerization of isobutene with n-butenes and with propene.ALSO:A liquid hydrocarbon composition of high anti-knock value consists of blended liquid polymers or hydrogenated polymers derived from the separate cross-polymerization of isobutene with n-butenes and with propene.  The preferred polymerization catalysts are made by calcining a mixture of a phosphoric acid and a solid adsorbent as described in Specifications 437,188 and 464,671. The cross-polymerization of isobutene and propene, which are suitably in equimolecular ratio, may be effected at about 93-165 DEG  C. and 34-41 atmos. with a contact time of 500-900 secs.  The products are fractionated, advantageously to recover polymer boiling below 150 DEG C. for blending with the isobutene-n-butene polymer, and unreacted gases which are returned.  The polymerization of isowith n-butenes may be carried out at about 135-165 DEG  C, and 30-45 atmos. with a contact time of 250-350 secs.  These temperatures and pressures correspond to the critical values for the mixtures treated.  Steam may be mixed with the reacting gases to maintain the desired degree of hydration of the phosphoric acid.  The isobutene may be prepared by selective polymerization from mixtures using solid phosphoric acid catalysts at normal temperatures up to 65 DEG  C., and depolymerization or by removal with 65-75 per cent sulphuric acid, conversion of the ester to tert. butyl alcohol and dehydration.  In an example, a C4 fraction is treated with a solid pyrophosphoric acid catalyst at 154 DEG  C. and 37,5 atmos. for 260 secs., the hydrogenated polymer being blended with the lower boiling hydrogenated polymerization product of isobutene and propene using a similar catalyst at 93,3-103 DEG  C. and 37,4 atmos.  Specifications 477,128 and 490,854 also are referred to.
