Title: Photopolymerization of monomers containing the ch=c grouping
Inventor: MUELLER FRITZ WALTER HELLMUT
IPC: G03F7/029
Filed: 1960-08-10
Abstract: Compounds containing the grouping CH2=C< are polymerized by exposing them to electromagnetic radiation having a wavelength of from 10-1 to 10-10 cm. in the presence of a thallium compound as a polymerization catalyst.  Polymerizable compounds specified are acrylamide, methacrylamide, N-hydroxymethyl and N-hydroxyethyl acrylamides, acrylic and methacrylic acids, calcium acrylate, acrylonitrile, methyl and ethyl acrylates, methyl methacrylate, vinyl acetate, butyrate and benzoate, vinyl methyl, ethyl isopropyl and isobutyl ethers, vinyl pyrrolidone, butadiene and mixtures of ethyl acrylate and vinyl acetate, acrylonitrile and styrene and butadiene and acrylonitrile.  The above compounds may be polymerized in admixture with small amounts of compounds containing at least two terminal vinyl groups, e.g. divinyl benzene, methylene-bis-acrylamide, triallyl cyanurate, divinyl ketone and diglycol diacrylate.  Thallium compounds specified are thallous oxide and hydroxide, thallous salts of the common inorganic acids, thallous formate, oxalate, formate-malonate and myristate and thallous methoxide; the preferred compound is thallous nitrate.  The effectiveness of the thallium compound as a catalyst may be enhanced by the use therewith of compounds such as gold, rhodium, silver and stannous salts, e.g. gold and rhodium chlorides and silver nitrate, a mixture of a gold salt and sodium nitrate, potassium iodide, thiourea, thiocyanates, ascorbic acid and dyestuffs such as cyanines, merocyanines, hemicyanines and styryls.  The polymerization may be carried out in solution in water or a water-alcohol mixture, or in aqueous dispersion containing dispersing agents such as long chain fatty acid sarcosides or taurides, the reaction products of ethylene oxide with a phenol, a fatty alcohol, an amine or a fatty acid, and long chain aliphatic sulphonates.  The polymerizing radiation may be ultra-violet or visible light, gamma-rays or X-rays.  The examples describe the polymerization of mixtures of acrylamide and methylene-bis-acrylamide in the presence of water.  The process may be used in the production of polymeric photographic images, for which purpose polymerization may be carried out in the presence of a colloid carrier, e.g. gelatin, polyvinyl alcohol, starch, glue, carboxymethyl cellulose, a polyamide, polyvinyl pyrrolidone or saponin, the photopolymerizable composition being coated on a suitable support.

Longitudinal displacement, in the direction of the arrow, of rod 2 causes actuation of a switch 8 as the tapered and enlarged rod portion 4 acts on the switch operating member, and removal of the operating force, e.g. by opening a door, allows spring 3 to restore rod 2 until its shoulder 9 engages a bent leaf-spring 14, while rotation of rod 2 causes one end of a pin 6 to move spring 14 out of engagement with the shoulder 9 so that rod 2 can be moved by spring 3 beyond the spring 14, thereby causing actuation of switch 8 by the tapered and enlarged rod portion 15. Re-closing of the door allows spring 14 to move back to its latching position. Rod 2 actuates the levers of one or more microswitches 8 via spring-loaded rollers 20.

Abstract: 332,457. International Harvester Co. of Great Britain, Ltd., (International Harvester Co.). Sept.. 21, 1929. Reaping, mowing, and harvesting machines.- A mowing machine having a front frame part rigidly attached to a tractor and a rear frame part pivotally swung on the front frame part is fitted with wheels which are normally locked against swivelling but are adapted automatically to be released for casbering movement when the cutter bar encounters an obstruction offering predetermined resistance. A housing 19 is rigidly attached by means of draw bars 20 to the tractor from which power is transmitted equally in all relative positions of tractor and mower to a flywheel 50, through a power take-off shaft 14 and shafts and bevel gearing enclosed in housings 43, 19 and 24. The housing 19 is also pivotally mounted in the triangular main frame 16, the sides of which are connected by brackets 17 each of which embodies a collar-part 18 loosely carrying a spindle 57 integral with a bifurcated yoke 56 carrying a trailing wheel 54. The spindle 57 carries a plate 61 provided with dwells receiving rises 64 in a spring-pressed plate 63. If the cutter bar 34 encounters an obstacle of sufficient resistance to overcome the action of the previously adjusted spring 58, the plates 61 and 63 become separated and castoring of the wheel 54 is possible. The cutting mechanism may be lifted clear of ordinary obstructions, through a rod 68, crnak 69, and link 70 by means of the lever 67.

Abstract: 503,965. Metal - working presses. WILCOX, R. L., HOYT, H. L., and WATERBURY FARREL FOUNDRY & MACHINE CO. Oct. 21, 1937, No. 28793. [Class 83 (iv)] Shearing; forging.-In shearing mechanism used in conjunction with upsetting machines presses and the like, the cutter bar is moved through the medium of articulated links which in normal operation remain substantially in alignment but which, in the event of an obstruction occurring, move about a connecting pivot and relieve the strain on the transmission. As shown, a pair of cams 18, 19 operate on rollers carried by linkage 22, 23 and transmit motion to a yoke 48 connected by an adjustable turn buckle element 49 with a link 44. The link 44 is pivotally connected to a link 43 pivoted on a slide 39 which in turn is connected to a link 40, rocker arm 37 link 35 and slide 33 on which the cutter 30 is mounted. In Fig. 4 is shown the links 44, 43 transmitting the pressure at the commencement of the cut. A roll 46 carried by the pivot pin 42 of the linkage has not engaged a cam surface 64. When the cut is furnished the cam surface diverts it slightly from the position in which the links are aligned and should an obstruction occur the slide 39 is prevented from moving forward and the pivot is forced downwardly and with it a block 45 which engages a slide 51. The resulting movement of the slide stops the feed of the stock.

Title: Measurement of phase shift
IPC: G01R25/00
Filed: 1939-10-27
Abstract: 533,282. Phase-difference measurements. STANDARD TELEPHONES & CABLES, Ltd. Oct. 27, 1939, No. 28830. Convention date, Nov. 15, 1938. [Class 37] Apparatus for measuring phase shift comprises two paths connecting a source of A.C. to a phase meter, an harmonic generator in each of these paths, phase shifting means preceding this generator in at least one of the paths, and means for including a circuit under test in one of the paths succeeding the harmonic generator. An A.C. generator 1, Fig. 3, supplies sinusoidal current to parallel circuits 2, 3. The circuit 2 includes an harmonic generator 4<1> of the impulse type and terminates in a mixer 7. The circuit 3 comprises a phase shifter 5, calibrated in degrees of phase shift at the frequency of the generator 1, an harmonic generator 4, and the circuit 13, 6, 14 under test, and terminates in the mixer 7. The mixer 7 consists of fixed and variable resistances arranged to terminate the circuits 2, 3 without permitting reaction of one circuit upon the other, and combining the outputs in desired proportions for transmission into a tuned amplifier-detector 8 which is tuned to select the frequency of the harmonic at which the phase shift measurement is to be made. The detector may include a rectifier and a direct current meter, in which case the phase shifter 5 is adjusted to produce the maximum reading on the meter. The phase shift at this frequency is then the phase shift of the phase shifter 5 multiplied by the order of the harmonic. In a modification, Fig. 4, by which the change in phase shift with frequency may be measured, a 4,000 cycle source 20 supplies two circuits. One of these is through an attenuator 24, phase shifter 25, harmonic generator 26, the circuit 27 under test, and mixer 29. The other circuit is through a spare circuit 21, amplifier 22, bandpass filter 23, alternator 24<1>, phase shifter 25<1>, and harmonic generator 26<1> to the mixer 29, which feeds a tuned amplifier-detector 30. The harmonic generators 26, 26<1> are adjusted so that equivalent harmonics produced by them are in phase when the same low frequency is applied to them in the same phase. Specification 477,875, [Group XXXV], is referred to.
