Title: A lifting rotor for an aircraft
Inventor: GIRARD PETER FRANK
IPC: B64C27/54
Filed: 1966-08-17
Abstract: 1,100,368. Lifting rotors for aircraft. RYAN AERONAUTICAL CO. 17 Aug., 1966, No. 36821/66. Heading B7W. A lifting rotor for an aircraft has a plurality of retractable rotor-blades 22 that are pivotally attached by pins 36 to the lower portion or shell 12 of a hollow central-body, which portion is fixed to a rotatable shaft 16 that also carries a plate 38 providing additional support for said pins, the upper portion or shell of said body being rotatable relative to the portion 12 and the plate 38 by a motor 54 through gears 52, 58 and provided with rollers 48 externally thereof in abutment with the leading edges 50 of the rotor-blades so that the latter can be partially retracted into said body while undergoing angular displacement from a position wherein they are radially orientated, as shown, to one wherein they are chordally orientated relative to said body, Fig. 4 (not shown). Retraction, or extension, of the rotor-blades can be effected during flight, the blades being retracted when the rotor is not required to provide lift, so as to minimize drag, and the aircraft is being supported by other means such as fixed wings during high-speed flight. The shaft 16 may be either driven or freely rotatable. A counterweight 44 may be attached to a tubular trunnion 34 that engages with each of the pins 36 and carries a transverse pin 32, which is coupled to a yoke 30 on a pin 28 having ball-bearings 26 thereon that are housed within a shank 26 for the corresponding rotor-blade, whereby the pitch of the blades can be varied and restricted vertical displacement of the blades is permissible. A friction pad 62 and a stop 46 engage with each counterweight when the blades are fully extended to sustain their radial orientation. The pitch of each blade is controlled by a rod 80 that is coupled to a lug 64 on the shank 24 by a torque tube 70 having pivotal couplings at either end, the rod being supported by an arm 76 pivotally supported by a radial pin 78 that is carried by a rotatable sleeve 79. The upper portion 18 of the central body is supported by bearings 17, 19 and includes apertures 40 for the blades that are shaped to prevent the pitch-angle of the latter being other than zero when they are retracted. Arcuate apertures 82 for the rods 80 are provided in the lower portion 12 of the central body.

IPC: G07F5/26
Filed: 1929-09-16
Abstract: 326,686. Crow, D. Sept. 16, 1929. Delivering articles selectively from a multiple arrangement of containers. - Articles are stored in vertical boxes 26, Fig. 2, each having two compart ments 27, 28, one compartment being posi tioned above each hinged bottom panel of a group of panels 1- 16, Fig. 1. Between adjacent boxes 26 are superposed horizontally slidable magazine trays 56, Figs. 2 and 9. Each hinged panel 1- 16 is supported by two tongues 1<2>-16<2>, 1<3>- 16<3>, one set of tongues 1<2>-16<2> projecting from parallel rows of bars A<1>-A<4> and the other set 1<3>-16<3> from transverse bars B<1>-B<4>. The bars A<1>-B<4> are connected by cords 17-24 to slidable members 29, 32, Fig. 3, having hooks 30, 33 normally held clear of a bar 31. A hook 30 associated with one of the bars A<1>-A<4> and a hook 33 associated with one of the bars B<1>-B<4> is moved into the path of the bar 31, against the action of a spring 38, when a key 1<4>-16<4>, Fig. 4, on a keyboard 39 is pressed. The bar 31 is then operated manually to engage the hooks 30, 33 and so slide one horizontal bar A<1>-A<4> and one transverse bar B<1>-B<4>. Both tongues supporting one panel corresponding to the operated key 1<4>- 16<4> are thus removed and the lowermost article in that column is released and delivered down a shoot, the remaining articles in the pile being supported by a clamping pin secured to the bars B<1> - - B<4>. Each vertical pile of trays 56 has a pivoted rod 64 with pins 66 which advance all the trays when a cord 68 is pulled. To each horizontal row of trays 56 is a sliding rod 60 having a pin 61 for each tray. The cords 68 and cords operating the rods 60 are connected to mechanism similar to that of Fig. 3 so that when a key on a board similar to that of Fig. 4 and the bar 31 are operated a column of trays 56 are moved by a cord 68 and an article on one of them is pushed off by a pin 61 on a rod 60. The keyboard 39 may have means to deliver to the purchaser a card marked with the value and name of the article corresponding to the push key 1<4> - - 16<4> operated.

Abstract: 942,249. Forced-flow steam boilers. H. VORKAUF. Oct. 2, 1962 [Dec. 30, 1961], No. 37366/62. Heading F4A. In a forced recirculation steam generator having tubes of diameter d, fitted at their inlet ends with nozzles or other throttling devices and with helical baffle inserts of pitch I within the tubes the inlet velocity w is chosen so that the ratio w<SP>2</SP>/d where w is given in metres/second and d in metres, lies between 5 and 20 and the pitch I of the helical insert lies between 0.5 and 1.5 w#d metres. By this means the water is constrained to flow along the walls of the tubes leaving a central passage through which the generated steam may pass along and out of the tube at greater velocity than that of the water.

Title: Generation of optical pulses

IPC: H01S3/107
Filed: 1970-08-07
Abstract: 1,273,728. Light modulation. INTERNATIONAL BUSINESS MACHINES CORP. 7 Aug., 1970 [25 Aug., 1969], No. 38155/70. Heading H4F. [Also in Division H1] When coherent linearly polarized optical pulses, e.g. from a ruby laser are passed through an optically resonant medium, e.g. a ruby rod under conditions such that self induced transparency occurs, i.e. the phenomenon wherein the shape and intensity of a light pulse are such that a medium with an absorption line of a wavelength approximately equal to the wavelength of the light in the pulse transmits the pulse without loss, as though transparent, and when the centre frequency of the pulse is displaced to one side of the absorption line, application of an axial magnetic field to the medium causes each pulse to be separated in time and space into its two oppositely circularly polarized components. It is said that the magnetic field causes Zeeman splitting of the absorption line into two components respectively associated with the two polarized light components, so that the two circularly polarized components of the original pulse move at different speeds within the medium and become separated. In a first embodiment, a solenoid applies a variable magnetic field to the ruby rod to vary the separation of the two components. In particular the separation may be equal to one half of the spacing of the input pulses, and a quarter wave plate may convert the output pulses into a regular series of pulses each linearly polarized at 90 degrees to the preceding and following pulses. Such a series may be converted by a similar arrangement, using half the original magnetic field, into a corresponding series of four times the original input pulse frequency. In a second embodiment, microwaves are propagated along a slow wave structure, e.g. a helix, at the same velocity and synchronously with the passage of optical pulses through the ruby rod contained within the slow wave structure, under the control of a master oscillator. In this case it is shown that the maximum separation of the component optical pulses within the medium equals one half the microwave period. Information is used to modulate the microwave signal so that for a binary signal for instance, the pulses are either single or double (or merely broadened) or, by varying the phase of the microwave, the time sequence R-L or L-R of the two polarized components may carry the information.
