Title: Tape regulating devices for stock quotation projectors
IPC: G03B21/134
Filed: 1930-03-18
Abstract: 346,133. Feeding webs. NEWS PROJECTION CORPORATION, 60, Broad Street, New York, U.S.A.-(Assignees of Eitzen, A. D. ; 60, Broad Street, New York, U.S.A.) March 18, 1930, No. 8661. Convention date, April 23, 1929. [Class 100 (i).] In a combined stock-quotation ticker and projector, the tape is fed to a rewinding reel by a continuously driven feed device, and a lever, resting upon the tape between the ticker and projector, is adapted to be raised upon stoppage of the ticker, to cause a roller to press the tape against an abutment to hold the tape against movement by the feed device. The tape 11 passing from the stock ticker 10 is drawn over the projector 12 by a feed pulley 23 loose upon a shaft 16 but normally clutched thereto by a pair of friction discs, one fixed to the shaft and the other slidably keyed thereto and pressed against the pulley by an adjustable spring. The shaft 16 is driven continuously by worm gearing 20, 18 and belt 19 from an electric motor, and drives the rewinding reel by a slipping belt 22. The tape-gripping device comprises an abutment 13, Figs. 1 and 5, against which the tape is adapted to be pressed by discs 47 carried by one lever 42 of a pair of toggle levers 42, 37. The upper end of the lever 37 is pivoted to a block 39 supported from a bracket 41 and the lever 42 is also connected to the block 39 by a link 44. To enable the pressure of the discs 47 upon the tape to be adjusted, the block 39 is connected to the bracket 41 by an adjustable screw 57. The lower end of the lever 37 is connected by a link 35 to the short arm 33 of a bell-crank lever 30 mounted on a pivot 31, the long arm of the lever being provided with a finger 32 resting on a loop of tape between the ticker 10 and projector 12. When the ticker is discharging tape, the lever 30 falls by gravity and, through the link 35, breaks the toggle 42, 37 to raise the discs 47 to allow the tape to be fed by the pulley 23, but, upon stoppage of the ticker, the lever 30 is raised and the toggle straightened to cause the discs 47 to grip the tape. In this position the discs 47 also engage a brake plate 48 to prevent them from rotating. To cause a dwell between the starting of the ticker and the release of the tape by the discs 47, a pin-and-slot connection 34, 34<1> is provided between the arm 33 and link 35 and a friction joint is provided between the link 35 and toggle lever 37 by means of a spring 59 so that the friction of the pin 34 in the slot 34<1> will be insufficient to actuate the toggle. The whole of the tape-gripping device is preferably mounted on a plate 49 hinged to the top of the projector 12 and secured by a latch 52. A spring 54 mounted in a housing in the plate 49 serves to raise the plate slightly upon release of the latch 52. Specification 313,257, [Class 100 (i), Feeding and delivering webs &c.], is referred to.

Title: Improvements in vacuum dehydration
IPC: F26B5/04
Filed: 1945-10-09
Abstract: <PICT:0620653/III/1> Materials are dehydrated by exposing the material to a vacuum, vaporizing in a separate chamber a solvent which is completely miscible with water and has the property of reducing the freezing point of water, introducing water vapour from the material undergoing dehydration and the vaporized solvent simultaneously into a condensing chamber so as to form a liquid mixture, and then withdrawing this mixture from the system.  Methyl, ethyl, isopropyl alcohol or acetone may be used as the solvent.  The material is introduced into trays 16 in chamber 10 which is connected by conduit 90 to condensing chamber 60.  The latter is also connected by conduit 92 to container 96 which contains the solvent.  The system is evacuated by pump 70.  Each tray is heated by circulating hot fluid through coils 18; refrigerating fluid is passed through coils 62, and valve 94 is opened.  Water vapour from chamber 10 and solvent vapour from container 96 are simultaneously drawn into condensing chamber 60 where they condense as a low-freezing liquid mixture on coils 62.  The condensate drops into funnel 72 and is withdrawn from the system by pump 76.

Title: Process for increasing the reactivity of naturally or artificially shaped articles or materials
IPC: D06P1/52
Filed: 1936-03-26
Abstract: As a modification of the process described in the parent Specification, for increasing the reactivity, especially towards acid reagents, of naturally or artificially shaped articles or materials made of or containing protein or chemically modified protein, the treatment with an alkylene oxide, sulphide or imine is replaced by a treatment of the materials, not dyed with acid dyestuffs, with a quaternary derivative of an alkylene imine which reacts with splitting of the ring or with an analogous ternary derivative of an alkylene sulphide, and the treatment is effected at a raised temperature.  Specified articles or materials treated are wool and other animal hair, including wool which has been treated with oxidizing, chlorinating or chroming agents, skins, leather, natural silk, artificial silk of fibroin or casein and cellulose artificial silk containing protein substances. Specified quaternary ammonium compounds used are diethylethyleneiminium chloride, pentamethyleneethyleneiminium chloride (obtainable by treating b -oxyethylpiperidine with hydrogen chloride and allowing the aqueous solution of the resulting b -chlorethylpiperidine to stand), pentamethylene-2-oxypropyleneiminium chloride (obtainable by molecular transposition of 3-chloro-2-oxypropylpiperidine), methylbutylethyleneiminium methosulphate (obtainable by the action of dimethyl sulphate on N-butylethyleneimine in alcohol), 2-oxy-1 : 3-propylenemorpholinium chloride (obtainable by reacting morpholine with epichlorhydrin in cold aqueous solution and allowing the product to stand), the quaternary spiran from piperazine (1 mol.) and epichlorhydrin (2 mols.) and the dihydroisoindole derivatives obtainable by reaction of a secondary amine, e.g. piperidine or morpholine, with o-xylylene dibromide. Specified ternary sulphonium compounds are the alkyl iodides of 1 : 2-propylenesulphide and of its 3-chloro derivative.  The shaped materials may be heated with a solution of the alkylating agent in water or in an organic solvent or may be impregnated, printed or padded with a solution or thickening containing it, left to stand or centrifuged, and stored under moist conditions and at a raised temperature until the reaction is completed.  Thus, a woollen fabric so impregnated may be stored in a moist atmosphere for 12--16 hours at 70 DEG  C. and the agent may be fixed by steaming.  In examples: (1) a mixture of equal parts of wool and viscose staple fibre is impregnated at room temperature with a 10 per cent solution of pentamethylene-2-oxypropyleneiminium chloride, pressed for 20 minutes and stored for 16 hours at 50 DEG  C.; the affinity, especially of the wool, for acid dyestuffs, such as Alizarine direct blue A, Orange II, Thiazine red R and Pegu brown, is increased; (2) woollen piece goods are similarly treated with diethylethyleneiminium chloride.

Patent GB-454301-A (GB)
Title: Improvements in and relating to knitting machines
IPC: D04B9/38
Filed: 1935-03-25
Abstract: 454,301. Knitting-machines. LOMBARDI, V., 28, West 23rd Street, New York, U.S.A. March 25, 1935, No. 9209. [Class 74 (ii)] Relates to the use of selective elements for controlling knitting elements such as latch or bearded needles, jacks, sinkers, yarn controllers, &c. in the production of tuck fabrics or of fabrics of the type shown in Specification 242,801, [Class 74 (ii)]. Fig. 1 shows the invention applied to a machine with latch needles which slide in the tricks of a stationary cylinder 40. Beneath each needle is a jack 43 rocking on a fulcrum 44. The jack is held frictionally within its trick with the lower end normally projecting outwards. Shoulders 46, 47 may thus be engaged by cam bits 58, 59 in a revolving pattern drum or wheel 51. These bits slide in radial slots 60, 61 formed in the body 62, 63 of the wheel 51 and travel round on stationary ribs 65, 68. The jacks may be of two different forms disposed alternately, one form 43a operable by the bits 58 and the other form 43b operable by the bits 59. Each of the six or other number of wheels 51 in use is geared to stationary toothed rings 55 or 88 by pairs of gears 54, 56 connected by springs to reduce backlash. The two sets of bits 58, 59 are preferably staggered. They are projected by pivoted spring-urged outthrow cams. The projected bits 58 push the lower ends of the corresponding jacks into the cylinder tricks so that they fail to engage cam 77, Fig. 2. The bits 59 push the jacks half-way in and these jacks are moved up by the cam 77 far enough for the corresponding needles to form tuck stitches. Needles corresponding to unselected jacks form full stitches. The jacks are re-set by a cam acting on butts 80, and by a roller on a spring arm. The jacks ride on a bar 841 while within range of a pattern wheel. Sinkers or web holders 86 may be similarly selected. Either set of bits can be placed out of action by a companion wheel 97, the studs on which shift the plates carrying the outthrow cams so that the bits do not engage the jacks even when projected. Each wheel 97 is turned on its axis when required by a ratchet device 103 actuated by trippers set round the machine and controlled by pattern chains. In another form, applicable to a machine with sliding bearded needles the leaves of the needle cylinder 40j are shaped to mesh with a gear 206 on the pattern-wheel, radial bits 207 of which enter the tricks 41j and engage rockers 43j located therein. The wheel can be moved radially out of engagement with the cylinder. The bits 207 are of two lengths. In another form, also applicable to the selection of sliding bearded needles, two sets of long and short bits act on two rows of projections formed in the upper portions of the rocking jacks. In another form the ends of the upper bits are turned up while the ends of the lower bits are turned down.
