IPC: B04B1/00
Filed: 1958-04-18
Abstract: 881,665. Respiratory apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 1, 1959 [April 18, 1958], No. 12312/58. Class 81 (2). [Also in Group XX] Apparatus incorporated in a respiratory mask for separating- from an airstream dust particles of sizes lying between an upper limit and a lower limit, comprises inner and outer drums 10, 1, mounted on a shaft 2 so as to be rotated by a motor, not shown, the throughput velocity of air being such that particles of size below the lower limit are mostly carried through the pump without deposition and the inlet port is so shaped and dimensioned that particles larger than the upper limit are centrifugally accelerated to a velocity exceeding the intake velocity and particles of the desired sizes are deposited in the chamber formed between drums 1, 10. Air enters between a flange 16 and a cap 12, the latter having a frusto-conical upper surface to prevent sedimentation of particles thereon, and passes through a gap in cap 12 to the chamber where dust is deposited on a removable cylinder 17. The air leaves by aperture 4, which effectively controls the rate of flow through the apparatus, and radial tubes 6. The bore 5 of shaft 2 is provided for use when calibrating the apparatus by a method which is described. In a modification the tubes 6 have replaceable jets inserted therein of various sizes to control the rate of flow through the apparatus and the cylinder 17 has a horizontal top cover.

A device such as a feeder tray 9 carried on swinging spring-loaded links 11 is oscillated with adjustable amplitude by a flexible strap 16 which is deflected by a motor-driven eccentric 8, one end of the strap 16 being attached at 15 to the tray 9 while the other end 16a is attached to a stationary frame 17 which is adjustable about studs 18 to vary the angle by which the strap is wrapped around the eccentric 8, and hence vary the amplitude of oscillation of the tray 9. A pinion 20 mounted in the frame 17 and engaging a fixed quadrant 22 is manually rotated to adjust the position of the frame. A coaxial locking knob is also provided. The swinging links 11 carrying the tray 9 are biased by springs 14 reacting against a fixed frame tie 2. The strap 16 may comprise one or more metal or other bands, cables, cords or chains, and may bear directly on the rotating eccentric or on an intermediate member (e.g. a sprocket wheel) in which the eccentric rotates. In a modification dispensing with the pinion 20 the outer end of the frame 17 has a slotted quadrant connection with, and may be adjustably clamped to, an arm movable about the rotary axis of the eccentric 8.

Title: Improvements in and relating to crystal rectifiers for wireless reception
IPC: H01L29/00
Filed: 1924-05-21
Abstract: 238,610. Compare, A. May 21, 1924. Crystal detectors.- In a crystal detector of the type in which one contact member is adapted to be rotated and automatically withdrawn from the other contact member. the means for causing the said movement of the first member are coaxial with the part carrying that member. As shown, the crystal cup d is carried by a rod d<1> provided with a diametral pin d<2> engaging parallel sided slots in a fixed cup d<7> and V-shaped slots d<3> in a cup d<4> rotated by a knob d<5>. The rod d<1> passes through the base d<8> of the cup d' which is secured in a standard b and rotatably carries the cup d<4>. Rotation of the knob d<5> causes the pin d<2> to ride up the slots in the cup d<7>, the pin being pressed down the adjacent slots by a spring d<6>. The cat's whisker e is carried by a tube e<1> eccentrically mounted in a knob e<3> which carries a concentric cup e<5> having slotted sides to make contact with a bush c<1> carried by the standard c. The point of the cat's whisker passes through an opening in a nozzle e<2> and its ther end is secured in the tube e<1> by a plug e<4>. The knob e<3> may be formed with a notched flange e<6> engaged by a projection c<2> on the stand c. The parts may be enclosed by a glass 'tube f carried by a pair of flanged holders c<4>, b<4>. The crystal cup may be arranged for rotation only, the automatic movement described above in connection with the crystal being applied to the cat's whisker, which is mounted eccentrically in its carrying member. The cast's whisker may be replaced by a, crystal to provide a two-crystal combination. In modifications. the cat's whisker, enclosed in a tube is mounted on a rotatable crank arm, or the cat's whisker may be secured to one projection on a spindle with its point passing through a hole in another projection on the spindle. In another modification the slots in the cup d' may be of wave form, the V-shaped slots in the cup d<4> being replaced by parallel sided slots. The knobs may be calibrated and used in conjunction with pointers so that the crystal and cat's whisker may readily be placed in any desired position.
