Unmodulated V.H.F. carrier is applied to terminal 5 of diode d over seriesresonant circuit FV1: the diode d is biased by means of circuit V, and amplitude-modulated V.H.F. signal obtained at terminal 2. Circuit FV2 is resonant at the V.H.F. carrier frequency. In a second embodiment, amplitude-modulated signal is applied via terminal 4, Fig. 10, and unmodulated V.H.F. carrier via terminal 1, to diode d. Amplitude-modulated V.H.F. signal is obtained at terminal 2, across circuit F V  resonant at this frequency: series-resonant shunt circuits Fm and Fi are tuned respectively to the sum and difference frequencies. The Specification also describes a modification of this circuit using a 3-dB coupler (Fig. 12, not shown) and one using a circulator (Fig. 13, not shown).

Abstract: 1278430 Conveyers; suction transfer heads KAMAN AEROSPACE CORP 18 Nov 1969 [5 May 1969] 56392/69 Headings B8A and B8H Sweets 24 of different kinds are transferred simultaneously in sets of three by a transfer apparatus 37 from roller shoots 36 to predetermined compartments in boxes 22 moved stepby-step on a conveyer 20 between successive stations where further sweets are inserted. Conveyer 20: Figs. 3, 4.-The boxes 22 are moved along plates 41 by pushers 48 carried by a beam 50 moved forwards, downwards, backwards and upwards. The upward movement is derived from cam 84, bell-crank 76, push-rod 74, crank arm 72 and crank arm 64. A roller 62 carried by the arm 64 engages the bottom of a yoke 58 sliding in bearing block 70. A similar yoke 58 (not shown) is similarly operated by a second push-rod 82. The two yokes 58 support the beam 50 on rollers 60 for longitudinal movement provided by a lever 94 oscillated about a pivot 96 by the engagement of a roller 95 on a crank disc 90 driven by a motor 110 which also drives the cam 84. Feeder bowls 28: Figs. 12, 13.-Batches of sweets 24 are placed on loading trays 26. Each tray 26 is carried by blocks 208, 210 mounted on springs 212, 216. The corresponding bowl 28 is secured between circular plates 224, 226 and is vibrated angularly by a shaker motor 196. The movement also passes from a block 230 secured to the plate 224 to an anvil 238 carried on a post 236 secured to a fixed block 206. The anvil 238 strikes a screw 240 carried by a block 210 secured to the tray 26 which is thus vibrated linearly. Shoots 36: Figs. 6, 8, 10.-The sweets 24 pass from the feeder bowl 28 down rollers 180 carried by shoots 36. Each shoot 36 is carried by a bar 164 adjustable at 162 and 168. Each shoot 36 is formed in two parts 176, 178 displaceable relative to one another by rotation of cam plates 184 about axes 172. Transfer apparatus 37: Fig. 10.-The sweets 24 are transferred into the boxes 22 by suction devices 314 adjustably mounted on pick-up units 312. Each pick-up unit 312 is mounted on an arm 128 pivoted about an axis 123 and maintains its orientation as the arm 128 swings it over to the conveyer 20 so that the sweets 24 drop into the boxes 22 when released. A bracket 150 movable along the length of the conveyer 20 carries column 120, on which is mounted the arm 128, for adjustment as required.

The member 32 is driven by the output shaft of the motor through gears (60) and serves to effect limited operation of the motor in response to actuation of a rotary selector-valve (40) associated with the ports 31a, 31b, 31c. A second embodiment of the valve, Figs. 6 to 9 (not shown), differs from that according to Figs. 4 and 5 in that the annular grooves in the rotary member are dispensed with, part-annular grooves (34<SP>1</SP>, 35<SP>1</SP>) being formed in the sleeve 31 to effect the grouping of alternate spaces between the lands. Alternatively, a plurality of grooves or holes (not shown) may be formed in the sleeve to effect said grouping. The rotary member may be provided with more than six lands, Fig. 10 (not shown). The valve may be in the form of a cylindrical sleeve (310), Fig. 15 (not shown), containing an axially-movable spool-type member (320), alternate spaces between lands on said member being interconnected to form two separate groups by holes (340, 350) within the member. Three equidistantly spaced ports (310a, 310b, 310c) in the sleeve are equivalent to the ports 31a, 31b, 31c in the embodiment according to Figs. 4 and 5.

In one method described a log Fig. 6 is placed on a machine having a plurality of pairs of spaced jaws, and the jaws of each pair are urged together to compress the log see Fig. 8, Several of the pairs of jaws are displaced transversely of the axis of the log to bend the log, is indicated by the dot-dash line in Fig. 6 and each pair of jaws is rotated about the axis of the log to apply torsion thereto. A shearing force may also be applied by moving one jaw of each pair upwardly or downwardly relative to the other, as indicated by the lower arrows in Fig. 8. The process is repeated until the chips are of the desired size, e.g. 50 to 150 mm. long and 1 to 20 mm. in cross-sectional dimension. The cross-sectional dimension of each chip being determined by rolling it between a pair of spaced corrugated plates. The chips are then cleansed by screening and may be arranged in parallel, secured by a binder, and moulded into products, e.g. planks, porous boards, or furniture. The forces applied to the logs may be varying, alternating or pulsating.

Patent GB-583160-A (GB)
Abstract: 583,160. Aircraft gun-sights. HILL, F. W. May 31, 1935, No. 15858. [Classes 92 (i) and 92 (ii)] Relates to gun-sights for use on gun mountings of the " ring " type in which sight corrections for "own speed" are provided by a rotary crank-arm maintained in the line of flight and having a length adjustable to suit aircraft speed. According' to the invention, the gun is provided with two U-shaped elevating arms 3, 7 pivoted at 8; 9 respectively to the rotary ring 2, and the "own speed" crank-pin 30 is maintained in the line of flight by a gearwheel 2a engaging the fixed ring and driving a flexible shaft 16 in the arm 3. The path of movement of the crank is maintained parallel to the ring by the arms 3, 7 and a connecting bracket 12 supporting the crank. In the form shown, the horizontal gun trunnions 15 are carried by a vertical pivot 13, Fig. 3, rotatable in the bracket 12. In order to maintain the crank-arm parallel to the line of flight, both when the gun is trained on its pivot 13 and when the ring is rotated, the vertical pivot supports a casing 27 for pinions 24a, 25, 26 driving the crank. The pinion 24a is mounted on a spindle 23 in the vertical pivot and is driven from the gun ring through the pinion 2a, dexible shaft 16, clutch 18 and helical gear 22. When the gun is independently rotated for training on its vertical pivot 13, the pinion 24a is locked and gears 25, 26 function epicyclically to keep the crank-driving wheel 26 fixed in space. The movement of the crank is also unaffected by elevational movements of the gun arm 3. The initial adjustment of the crank for ground drift is effected by releasing the clutch 18 and rotating the knob 21. The crank is adjusted for aircraft speed by the knob 34. The bar 35 carrying an illuminated ring-andbead reflex sight 40 is connected by universal joints to the crank-pin at 30 and the gun at 39. Adjustment for range is effected by a knob 32. The gun ring is traversed by the gunner using a back rest, compensation for slipstream resistance being effected by springs acted upon by rollers engaging an eccentric track. The weight of the gun and gun arm are compensated in elevation by rubber cords 5. The gun arm is locked in elevation and the gun ring in training by catches operated by twisting a grip on the gun arm.
