Title: Improvements in rotary winged aircraft
IPC: B64C27/51
Filed: 1945-11-15
Abstract: 602,994. Rotary-wing aircraft. CIERVA AUTOGIRO CO., Ltd., PULLIN, C. G., and SHAPIRO, J. S. Nov. 15, 1945, No. 30596. [Class 4] A rotary-wing aircraft comprises a sustaining rotor including damping means operative to apply restraint to certain flapping motions of the blades and reactive from blade to blade and not from the blades to the hub, in such manner that flapping motions of a frequency once per revolution do not substantially alter the configuration of the damping system and are therefore substantially unrestrained, but flapping motions of a higher frequency (twice or three times per revolution) are subjected to restraint. The damping means are such that their resistance to blade displacement increases with the rate of displacement in accordance with a linear or non-linear law. The dampers may be " tuned " to give critical damping at a selected harmonic frequency. In one form, Fig. 1, the blades 13a, 13b of a twobladed rotor are mounted on flapping pivots 12 and are formed with arms 14a, 14b interconnected by a hydraulic damper 15. In a second form, Fig. 3, the blades 13a-13d of a four-bladed rotor are formed with arms 14a- 14d connected independently in pairs by dampers 15ac and 15bd. In a third form, Fig. 4, dampers 15ab, 15bc and 15ca are connected by ball-joints 17a-c to upright arms formed on rings 16a, 16b and 16c (not shown), rotatable on the shanks of the blades 13a, 13b and 13c (not shown) of a three-bladed rotor. In a modification, Fig. 6, the upright arms are rigid with the blades and are connected by universal joints 18a, 18b ... 19a, 19b ... to dampers 15a-c, the inner ends of which are connected to a central plate 21 carried by vertical link 22, ball-jointed to the hub at its lower end. The inner ends of the dampers 15b, 15c are connected by universal joints 20b, 20c, 24b, 24c, to the plate, but the inner end of the damper 15a is connected directly by a horizontal pivot 20a.

Title: Automatic control of the ratio of the quantities of two streams of media
IPC: G05D11/13
Filed: 1963-08-01
Abstract: 998, 938. Automatic flow control. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Aug. 1, 1963 [Aug. 3, 1962], No. 30613/63. Heading G3R. In a system for automatically controlling the ratio of two rates of flow, electric pulses having repetition rates corresponding to each rate of flow operate switches to charge condensers and discharge them into a common reservoir condenser controlling the ratio, a further condenser being charged from a voltage dependent on some other variable of the material and discharged into the reservoir condenser to modify the control effect. In Fig. 1 flow meters F A , F B  are respectively associated with pipes A, B the flowing media in which may be gasolene to be blended. Electric pulses produced by the flow meters at repetition rates dependent on the rates of flow are caused to operate switches O A , O B  so that condensers C A , C B  are respectively charged to voltages corresponding to the rates of flow and discharged in opposition into a reservoir condenser C so that any difference, reprepresenting a change in the flow ratio, is effective to adjust a valve controlling the rate of flow in pipe A. The desired ratio is set by means of a potentiometer R 1 P controlling the charging voltage of condenser C A . In order to introduce a variation of this ratio in dependence on another variable of the medium, such as viscosity, vapour tension, conductivity or temperature (e.g. for constant mass flow), the other variable is caused to vary a voltage E 2 , and an auxiliary condenser C E  is periodically charged from this voltage and discharged into reservoir condenser C by a switch O E  operating synchronously with switch O A . Alternatively switches O E  and O B  may be synchronized, in which case it is desirable to arrange for adjustment of voltage Eg when potentiometer R 1 P is adjusted or to supply condenser C A  through a potentiometer instead of condenser C B . A bridge circuit, Fig. 4 (not shown), having preset resistors and resistors dependent on the temperature of the media, may be arranged to produce the voltage Eg variable with temperature for mass flow ratio control. Further auxiliary condenser circuits may introduce control in dependence on more than one additional variable. Maintenance of the relative rates of flow of more than two streams is also referred to.

Title: A process for manufacturing minute polymeric capsules
IPC: B01J13/08
Filed: 1966-07-08
Abstract: 1,099,066. Forming microcapsules. NATIONAL CASH REGISTER CO. July 8, 1966 [Aug. 18, 19651, No. 30800/66. Heading B8C. Minute particles or droplets of material are encapsulated in a hydrophobic film-forming polymer by dispersing them in a polymer wherein an adjustment of temperature causes separation into or formation of during dissolving rich and less rich polymer phases, the former of which coats the material with the polymer, no additional chemical phase separator being necessary. The process permits recovery of the solvent by re-cycling. The solvent is organic and " poor " i.e. effective at higher than at lower temperatures. A suitable pair of a polymer and a solvent or solvent mixture is selected, e.g. an ethyl cellulose and cyclohexane. The polymer is dissolved in the solvent with heating as necessary and the solution temperature lowered, or the polymer and solvent are heated, until two phases of solution are formed, of which the more voluminous has the lower polymer concentration, and acts as a vehicle for the other polymer rich phase, which is dispersed throughout it in droplet form by agitation. The particles of encapsulable material, e.g. aspirin, various inorganic salts, amphetamine sulphate, gelatin, a range of organic compounds or aqueous solutions which are added before or after temperature adjustment, become coated with the polymer-rich phase material. The walls harden by solvent loss as the temperature lowers further.
