Title: Improvements in the Treatment of Nitrate of Ammonia.
Inventor: HOWORTH FRANKLIN WISE
IPC: C05C1/02
Filed: 1917-04-10
Abstract: 117,823. Haworth, F. W., (Elektrisk Norsk Hydro Kvoelstofaktieselskab). April 10, 1917. Manures. - Ammonium nitrate is obtained in dry granular form suitable for agricultural purposes by drying a moist mixture of ammonium nitrate with bog iron ore or kieselguhr at a temperature not above 130‹ C. with agitation. A small quantity of plaster of paris (gypsum) may be added to the ammonium nitrate before treatment, and the suspension of bog iron ore which is preferably employed may be made more viscous by adding gelatinized starch, kieselguhr, potassium salts, or ammonium salts. The drying may be effected in two stages, first at a comparatively low temperature such as 20-40‹ C., and then at a higher temperature such as 100‹ C.

Abstract: 1414575 Coated products EASTMAN KODAK CO 1 Feb 1973 [3 Feb 1972] 5118/ 73 Heading B2E [Also in Divisions C3 and G2]  A lithographic support is produced by coating a substrate with a solution or dispersion (aqueous or non-aqueous) of a hydrophilic acrylamide resin and an aldehyde, the weight ratio of resin to aldehyde being from 4:1 to 99:1, and drying the coating, e.g. between room temperature and 80‹C, whereby a subbing layer of water-insoluble resin is formed on the support. Water-soluble resins are preferred, e.g. polyacrylamide and copolymers of acrylamide with monomers such as acrylic acid, vinyl acetate and N-methacryloyl-N- cyanoacetyl-hydrazine. The aldehyde may be a monoaldehyde such as formaldehyde or acetaldehyde, a dialdehyde such as glyoxal or glutaraldehyde, or a polysaccharide derivative containing two -CHO groups in each repeating unit. The coating may optionally include a wetting agent, surfactant, dye, pigment or buffering agent. The substrate to which the coating is applied may be of paper, resin coated paper, zinc, aluminium, anodized aluminium, copper, steel, glass, polyamide or polyolefin; aluminium substrates are preferred.

Title: Improvements in or relating to the manufacture of flexible metal hose
IPC: B21D15/04
Filed: 1958-02-18
Abstract: 881,154. Helically - corrugating tubes. POWER AUXILIARIES Ltd. (D. K. Manufacturing Co. Inc.). Feb. 18, 1958, No. 5215/58. Addition to 821,940. Class 83 (4). A method of helically-corrugating tubing as claimed in Claim 1 or 2 of the parent Specification in which the guide or finishing blade or disc is considerably thinner than the profile produced by the swaging blade or disc and has a lesser helical pitch so that corrugations of a relatively close pitch are obtained. A blade carrier 1 is screwed on to the end of a hollow machine spindle 8 through which the tube is axially moved as the spindle rotates therearound. A first helical blade 2, extending about three-quarters of a turn, is secured to a helical end face 9 of the carrier 1, then a tapering helical washer 3, then a second helical blade 5, of about half the thickness and pitch of the blade 2 and extending over a full turn, and then a clamping washer 6, the whole being secured together by screws, a wedge 4 separating the beginning of the blade 5 from the carrier 1. The blade 2 may be chromium-plated beryllium copper and has a lead-in portion 14 and corrugation forming portion 13 of decreasing radius, the inner tube-engaging edge of the blade 2 being of constant radius. The blade 2 may be thin only at its tube-engaging edge. The blade 5 serves to force together the corrugations produced by the blade 2 to reduce their pitch to a value equal, for example, to the depth of the corrugations.

Title: Improvements in methods of knitting on circular knitting machines of the superimposed needle cylinder type
Inventor: WIDDOWSON ALBERT HENRY
IPC: D04B9/10
Filed: 1965-02-06
Abstract: 1,083,664. Knitting-machines. WILDT MELLOR BROMLEY Ltd. Feb. 2, 1966 [Feb. 6, 1965], No. 5239/65. Heading D1C. In a superposed cylinder machine for producing links-links float jacquard fabric, needles to knit in the bottom cylinder at one feed are selected from a group selected at the previous feed. Tilting selector jacks selected at C, are raised by a cam 18 so that the associated jacks are raised by further cams 15, 16. Sliders 4 are thereby raised to transfer selected needles 3'. which may include some of those transferred from the top cylinder by cam 21, to sliders 5 in the top cylinder. The transfered needles tuck on their latches at stitch cam 19. The remaining needles 3<SP>2</SP> knit in the lower cylinder. Prior to the second feed, selector jacks of needles 3<SP>1</SP> in the top cylinder are raised by cam 24 and the jacks then raised by further cams 25, 26. The sliders are then further raised by cam 27 and engage the needles lowered from the upper cylinder. Selector jacks of needles to be transferred to the upper cylinder, including jacks of any of the needles 3<SP>1</SP> to be re-transferred. are selected at the next selecting station D. The corresponding jacks are then raised by cams 15, 16 so that the sliders rise to present the needles to the upper sliders 5. Transferred needles knit at the upper stitch cam 19. Needles 3<SP>1</SP> returned to the bottom cylinder knit at feed F2. while non-selected needles, which have remained in a low track, do not knit. The machine is also modified so that needles selected to tuck in the bottom cylinder at the first feed also tuck at the second. Bolt transfer cams (16, 21, Fig. 6, not shown) at the first feed are withdrawn, and needles are selected (at C) either to knit or tuck in the bottom cylinder at the first feed. A bolt cam (29) in the track of the bottom slider butts raises un-selected needles to tuck height. Needles tucking at the first feed. remain un-selected at the second feed and tuck again. All the remaining selector jacks and jacks are raised by cams (24, 25-6 respectively) before selection is made. Jacks of needles selected to be transferred to the top cylinder are further raised by a cam (15). All needles in the top cylinder are transferred to the bottom cylinder by cam (21), then those selected to knit in the top are transferred by transfer cam (16). Sliders of needles to knit in the bottom cylinder are raised by cam (14) but remain in the bottom knitting track, as their jacks passed below the transfer cam.

Filed: 1956-02-21
Abstract: 789,490. Hose reel mountings. STEWARTWARNER CORPORATION. Feb. 21, 1956 [March 8, 1955], No. 5347/56. Class 99(2). A hose guide 7 is carried by an arm 5 rotatable about the hose reel axis. The arm is rotatably mounted on bearing washers 3. In a preferred embodiment a stop 6 permits the guide arm 5 to rotate from a vertical position, Fig. 2, through approximately 75 degrees. The stop could be omitted or arranged to permit more movement of the arm. Disc 27 which has three grooves thereon co-operates with a second disc 28 to form a latch arrangement. If the hose is slowly released to allow the reel and discs 27 to rotate slowly in a clockwise direction under tension from a spring 15 then a wheel 32 is forced into a groove and the wheel 32 will hold the reel against clockwise movement when it is desired to rewind the hose the hose is pulled suddenly and then released to allow the reel to rotate at sufficient speed to cause the wheel 32 to bounce over the grooves.
