Title: Improvements in or relating to electromagnets for stepwise movement of a toothed member
IPC: F16H31/00
Filed: 1959-02-10
Abstract: 913,814. Ratchet gearing. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 10, 1959 [Feb. 13, 1958], No. 4625/59. Class 80 (3). [Also in Group XXXV] An electromagnet for step operation of a toothed member has a pivoted L- shaped armature, attached to one limb of which is one end of a pawl comprising a thin resilient rod 16. The free end of the pawl has limited movement in all directions perpendicular to its length but is constrained by a plate attached to the armature to advance the toothed member one step upon energization of the electromagnet. In the de-energized position the pawl is held clear so that the toothed member may be driven in the reverse direction by an opposed but similar device. As shown, the constraining plate 13 has a trapezoidal aperture 14 (Fig. 3) and a notch 17 which forms the rest and driving position for the pawl 16; during return the pawl is free to move across the aperture. Forward movement is limited by a stop 18 on the electromagnet frame, when the pawl, in the notch 17, prevents the ratchet wheel from overrunning. In an alternative arrangement (Figs. 4 to 6, not shown) a ratchet-wheel whose axis is parallel to the length of the electromagnet is driven by a pawl attached at a right-angle to the armature and constrained by the suitably shaped end of a U-bracket also attached at a right-angle to the armature. In either embodiment the ratchet-wheel could be replaced by a toothed rack.

Abstract: 655,465. Wood-planing machines. FISCHER SOC. ANON., G. Feb. 19, 1948, No. 4933. Convention date, Feb. 20, 1947. [Class 145 (i)] A limbed pressing beam for a plank thicknessing machine with a horizontal cutter shaft, comprises a pressing member in the form of a lever of the first order and a feeler controlling a feeler member which is mounted in front of the pointed end of the pressing member, the upper part of the pressing member and the upper part of the feeler member forming a scissors-like device in which a pressing pin limits the vertical stroke movement and produces the pressure of the pressing member. In the form shown, the feeler member 4, mounted on a shaft 3 and having a feeler 5, carries a pressing member 7, the upper parts of the members 4 and 7 forming a scissors-like device in which is placed a pressing pin 10. Rigidly connected to the pressing pin 10 is a guide pin 14 which is freely movable and slightly tilted in a hole 15 in a support beam 11. A spring 12 presses the pin 10 against the upper part 8 of the pressing member 7. When the plank meets the feeler 5, the limbed beam is rotated upwardly about the shaft 3 until the plank meets the pressing member when the pin 10 is clamped between the scissors-like upper members and is lifted from the bottom tongue 18 of the support 11, the spring then keeping the pressing member in contact with the plank. Should the plank have a projection, the pressing member is able to rise even when the pin 10 meets the upper tongue of the support 11 since the pin 10 overcomes the frictional resistance and moves in the scissors device towards the pivot 9.

Title: Improvements in the production of photographic emulsions
IPC: G03C1/015
Filed: 1948-02-24
Abstract: 655,082. Photographic emulsions. KODAK, Ltd. (Eastman Kodak Co., Hewitson, E. H., and McClintock, J. A.). Feb. 24, 1948, No. 5490. [Class 98 (ii)] Instead of the usual chilling, gelling, shredding and washing of a colloid-silver halide emulsion for the purpose of removing water soluble salts, the silver halide is coagulated and separated from the liquid portion of the emulsion after the first digestion step by addition of a water soluble salt of ammonium, an alkali metal or a metal of Group II having an atomic weight of less than 140, and a water soluble acid capable of lowering the pH of the emulsion to 4 or less in quantity sufficient to lower the pH to 6 or less. The liquid portion of the emulsion is decanted away from the silver halide grains and the latter are washed as completely as desired as by addition of water and further decantation and then redispersed in a colloid, usually gelatin, to form an emulsion which may be re-digested or ripened if desired. An example based on Wall's " good positive emulsion " formula in " Photographic Emulsions," 1929 edition, describes addition of a large proportion of sodium sulphate, and of enough sulphuric acid to lower the pH to below 3, to the digested silver bromo-iodide gelatin emulsion, when the silver halide grains settle rapidly out of the suspension and these, after decantation of the liquid and three water washings with further decantations, are treated with water and the full amount of gelatin and other additions of Wall's formula and the resulting emulsion is ripened in the usual manner. Further examples indicate the use of zinc sulphate and ammonium sulphate to effect coagulation, and hydrochloric and citric acids to reduce the pH; and numerous other salts and acids for these purposes are listed. The entire process may be effected by use of one container only, one operation following another immediately, so that time and equipment are saved. The process is differentiated from those which dehydrate the emulsion, as by addition of acetone, alcohol, or dehydrating salts such as anhydrous sodium sulphate so that the emulsion can be shredded and washed without resort to chilling operations, in that these dehydration processes retain most of the original gelatin which has been added to the emulsion, while in the present process a large fraction of the gelatin remains dissolved in the wash water and is poured off. A process of coagulating gelatin in which silver halide present is also carried down, by addition of Group IV metal salts such as those of lead, titanium, thorium or zirconium, also is referred to.
