Title: Improved apparatus for feeding paper sheets
IPC: B65H1/22
Filed: 1927-09-30
Abstract: 294,801. Giesecke, J., and Giesecke, H. Sept. 30, 1927. Sheet-separators; pile supports.-Sheets are fed from a fanned out pile which is obtained by advancing the sheets by tapes 27, 26, 17 driven intermittently at equal speeds and passing over rollers 28, 29, 24, 25, 16, 18 which are arranged in pairs of different diameters. The tapes cooperate with feed plates 30, 19, and an extension plate 20 which conducts the sheets to a registering-bar 21, from which the top sheet is taken by an oscillating suction bar 3 connected by links 6 to oscillating arms 4 connected by links 12 to crank pins 11 operated by mutilated gearing from a shaft 7. The bar 3 is guided by slots 2 in the frame 1, and directs the separated sheet to a conveyer roller 23. The sheets are guided by curved guides 38, 39, while passing around the rollers 25, 16. The advance of the tapes is controlled by a contact or feeler arm 40 on a shaft 41, Fig. 1, which is oscillated to and from the front edges of the fanned out pile by means of a cam 13 on the shaft 7 acting on a roller 42 on a lever arm of the shaft 41. The condition of the pile, as the arm 40 returns to the pile. determines the position of a bell-crank lever 46, Fig. 4, which controls the axial movement of a square shaft 55 fitted with a plate 56 having all inclined end which can engage a pin 60 on a sliding pawl 22 adapted to engage a ratchet wheel 49 if the pile needs advancing. The pawl 22 is put into operation only if the pile is to be advanced, and it is put out of action automatically at each oscillation of the oscillating lever 57 by means of a stationary plate 61. A spring bolt engaging recesses in the pawl 22 holds it in its operative or inoperative positions respectively.

Title: Regulation and excitation system for electrostatic generators
IPC: H02N1/10
Filed: 1955-09-13
Abstract: 773,031. Electrostatic generators. SOC. ANON. DE MACHINES ELECTROSTATIQUES. Sept. 13, 1955 [Sept. 13, 1954], No. 26174/55. Class 35. An electrostatic generator is excited by an excitation device controlled by a bias voltage derived from the output of the main generator. As shown in Fig. 1a, a generator GP of the insulating charge carrier type feeds a load P and is regulated by a bias voltage p derived from a potential divider R, this bias voltage causing an inverse change in the voltage E2 supplied by an exciting generator GE. The system is made more sensitive by the insertion of a constant opposing voltage source CT. The excitation generator GE is preferably of the electronic oscillator and rectifier type, and it is usually necessary to insert an additional electrostatic generator acting as a further amplifier to ensure that the variation of the control voltage p is effective to regulate the main machine. This intermediate exciter may be used to reverse the polarity of the main machine without switching, by making it of a construction which produces opposite potentials for opposite directions of rotation. Such a machine of insulating charge carrier type is shown in Fig. 7. In direction f1, the negative charges deposited from ionizer II under the influence of plate D1 which is positively excited from the source 13, are carried directly to output ionizer 12. In direction f2, the negative charges are reversed by ionizers and plates I3, D3, 14, D4 so that a positive charge passes to the output. A machine employing the same principle using conducting charge carriers, is also described. Specification 719,687 is referred to.

Title: Improvements in and relating to insecticides, fungicides and the like
IPC: A01N25/06
Filed: 1946-09-03
Abstract: Aerosols of pesticides are produced from a solution or dispersion of the pesticide in an organic liquid, having a boiling point of or below substantially 80 DEG  C. and capable of absorbing carbon dioxide gas under increased pressure and of releasing it when the pressure is reduced, which is submitted to CO2 gas under pressure in a projector from which it is released through a fine orifice, the aerosols being formed by the disruptive action of the CO2 and the rapid evaporation of the organic liquid. By using an orifice of 0.015 inch diameter and CO2 pressure of up to 250 lb. sq. inch aerosols of 2 - 10 microns diameter may be formed.  The smaller particles predominate when the boiling point of the organic liquid is below 70 DEG  C., e.g. in the case of acetone, chloroform, ether, ethyl formate, methyl acetate, methyl alcohol, methyl formate and methylal, and the larger when liquids of boiling points 70-80 DEG  C. are used, e.g. benzene, carbon tetrachloride, ethyl acetate and methyl ethyl ketone.  Nicotine, rotenone, extracts of derris and allied roots, tetramethyl thiuran disulphide, azobenzene, nitrophenols and D.D.T. are suitable pesticides, which comprise up to 35 per cent of the total composition and may include up to 15 per cent (total composition) of a non-volatile diluent, e.g. vegetable oils.  Stable solutions of the pesticide in the organic liquid may be produced by the addition thereto of an intermediate solvent, e.g. trichlorethylene and methylated spirits or a stabilizer such as cyclonexanone, but where such materials have a boiling point above 80 DEG  C. the amount so used must not exceed 15 per cent of the total composition.
