Abstract: 180,507. Leathern, J. April 11, 1921. Hem-stitching machines; needles, vibrating laterally.-When placing a stitch off the hem, the laterally-vibrating needle 21, of a sewing-machine, is vibrated back and forth while in the material so as to cause the needle to co-operate properly with its rotary loop-taker and to leave the material at the point of entry. A needle-holder 20, integral with a needle-actuating lever 19, is pivoted at 18 to a needle-bar 8, reciprocated vertically by the usual mechanism from the mainshaft 12. The other end of the lever 19 is pivoted to a cross-head 23, sliding in a groove 24 in an L-shaped needle-oscillating lever 25 pivoted at 27 to the frame and actuated, through a link 30, by a slotted lever 32.

Title: Lithographic printing plates and methods for manufacturing same
Inventor: BEATTY JULIAN LEE
IPC: B41N3/03
Filed: 1957-04-01
Abstract: 812,508. Printing surfaces. DICK CO., A. B. April 1, 1957, No. 10632/57. Class 100(2) [Also in Group XX] A planographic printing plate comprises a base sheet, e.g. of paper, plastic sheet or metal strip, and a continuous, water insoluble lithographic surface layer on the base sheet in the form of a coating comprising the reaction product of the combination in admixture of an inert filler. polyacrylic acid and a bivalent metal oxide or hydroxide, and an ink receptive. water repellant, hydrophobic imaging material in the form of a mechanically applied image anchored on to the underlying continuous, water insoluble surface layer. The lithographic surface may be applied in a single coating, the coating composition including ammonia, a water soluble polyacrylic acid and an inert filler in combination with an oxide or a hydroxide of a bivalent metal capable of forming an insoluble salt with the polyacrylic acid but which remains soluble in the presence of sufficient ammonia in the form of ammonium hydroxide or a water soluble ammonia salt. In an example 180 parts by weight of clay and 18 parts by weight of zinc oxide are formed into a slurry with about 100 parts of water. 160 parts by weight of a 25 per cent water solution of polyacrylic acid is neutralized with 100 parts of concentrated ammonium hydroxide and the polyacrylic acid solution then combined with the slurry. The composition is then coated on to the base sheet in coating weight of about 8-10 pounds per 3,000 sq. ft. of surface and allowed to dry, preferably at an elevated temperature between 200-350"F. Instead of zinc oxide, magnesium oxide or hy- 'droxide or other alkaline earth metal. oxide or hydroxide, e.g. calcium oxide, lead oxide and barium oxide may be used. The clay may be replaced by other inert fillers such as diatomaceous earth, satin white, chalk, talc and silica. The ratio of inert filler to metal oxide is preferably within the range of 2:1 to 20:1 and the ratio of filler and metal oxide to polyacrylic acid within the range 2:1 to 10:1. Insolubility of the coating may be improved by the addition of water soluble bivalent metal salts, e.g. the chlorides and acetates of zinc, magnesium, nickel, cobalt, calcium and barium, from solutions containing the salt in amounts from 5.25 per cent by weight. The coating may be applied to a surface already coated with an insolublized hydrophilic colloid. For the production of presensitized photolithographic plates the coating is first applied on to a base sheet or on to a sheet already coated with an insolubilized hydrophilic colloid and a sensitizing coating then applied. The sensitizing solution may contain 1 per cent by weight of the diazolith compound, 5 per cent sodium acetate and 94 per cent water.

Filed: 1929-04-05
Abstract: 309,151. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). April 5, 1928, [Convention date]. Electric clocks.-An electric clock system has two or more master clocks so arranged that when one master clock becomes fast or slow it is automatically cut out and replaced by another one. The two master clocks h', h<2>, if correct, simultaneously close their rotating contacts k<1>, k<2>, so that contact k<2> closes a circuit through a contact a and the winding A of a polarized relay w' which closes its contacts; through these contacts and the contact k' a circuit is closed to the lines s<1>, s<2> feeding secondary clocks. Also across lines s<1>, s<2> are a polarized relay P and a non-polarized relay l having armature contacts e, d. Normally those contacts are open, and one of them is always open so long as the master clocks are in synchronism. If one clock, say h<2>, loses or gains a few seconds, a second impulse of the same direction is given to winding A. Contact e is closed and contact d open upon the first impulse through A. On the second impulse through A of the same direction e remains closed but the non- polarized relay reacts to close d. A circuit through e, d is thus closed to operate bell f and heating coil b of thermostat g so that the latter opens contact a to cut out the incorrect clock h<2>.

Abstract: 614,006. Separation of gases. KAPITZA, P. L. April 8, 1946, No. 10782. [Class 8 (ii)] In a process for producing from compressed air liquid oxygen or oxygen rich liquid of predetermined composition, the gaseous phase of cooled partially-liquefied air in a state of equilibrium with the oxygen rich liquid phase is adiabatically expanded, e.g. by a turbine expansion engine 10, and is thereafter used to cool and condense the compressed air in tubes 5, the resulting oxygen rich liquid collecting at 7 being rectified at 16 at a pressure of the same order as that of condensation. In operation, compressed air is cooled by passing it through a regenerator 1 and exchanger 3 and is then partially condensed in the tubes 5, the gaseous fraction passing along a duct 8 through the exchanger 3 to the turbine expansion engine 10. Oxygen rich liquid is tapped off at 13. Specification 540,555, [Group XXVI], is referred to.

Title: Improved process for adjustably heating a liquid by means of steam
IPC: F24H1/00
Filed: 1928-04-14
Abstract: 288,650. Castellazzi, A. April 15, 1927, [Convention date]. Heating liquids.-The heating effect of steam in a pipe 3, 12, 24, traversing a liquid-container 2, 11, 23, for example, a radiator for heating buildings, is raised by controlling the amount of heating surface covered by condensate. The heating pipe 3 is connected at its end to piping systems serving for supply of steam and removal of condensate the pressures at inlet and outlet being substantially equal. In the examples, one steam main serves for both purposes, the heaters being connected directly at the outlet and through an uprising siphon-pipe at the inlet. The heating pipes may be inclined, Fig. 1, or horizontal, Figs. 5, 8. The control may be effected (1) by discharging the condensate from the heating body by an overflow, the sill level of which can be altered; (2) by discharging the condensate through an opening having a given passage area and working with a given head; (3) by discharging the condensate through an opening of determined area delivering into a space which is maintained at a given pressure. In carrying out (1) the variable weir may be obtained by a sliding plate 5, Fig. 1, the steam pipe 1 serving also for carrying away condensate being connected to the heating body at each end. In place of a sliding plate a flexible tube or movable inverted U pipe may be used. Fig. 5 shows a method of carrying out (2) a sliding plate 17 controlling an aperture 18, weirs 16, 19 being also provided. A rotating cylindrical valve or a flexible tube may replace the weir 19. The method (3) may be carried out as shown in Fig. 8, in which diaphragms 25, 26, 28 are provided in the heating body 24, the aperture 27 being of definite area. An outlet siphon 29 is provided with long and short branches 30, 31 which can be put into communication by passages in a valved tube 32. This valve 33 will control the difference in pressure in the two branches of the siphon, and hence the rate of outflow of condensate in conjunction with the fixed aperture 27. The heating effect may be varied automatically according to the temperature of the liquid heated, or at will from some distant point. Fig. 9 shows a liquid, for exampLe, mercury, filled bulb 42 in connection with which is a glass tube 41 having a plunger 40 operating a plunger 38 which controls the passage 34 connecting the two branches of the siphon 29, Fig. 8. If the bulb 42 is immersed in the liquid to be heated the temperature will be kept constant. If the bulb is not so immersed but is surrounded by an electric heating-resistance control of the valve and hence of the heating may be effected from a distance and may be exerted over one or more heating bodies simultaneously.
