Title: Man-powered flying machine
Inventor: GILHAM CHARLES ALFRED
IPC: B64C27/12
Filed: 1968-10-16
Abstract: 1,274,659. Manpowered helicopters. C. A. GILHAM. 3 Oct., 1969 [16 Oct., 1968], No. 49124/68. Headings B7G and B7W. A manpowered helicopter comprises an airframe provided with a rotor 14 adapted to provide both vertical lift and forward thrust, and a tail rotor 5 for steering the helicopter. The two rotors are driven by a common manpowered driving means comprising pedals 9 connected with the rotors by an assembly of shafts, rightangled drive mechanisms and universal joints (Fig. 6, not shown). To take off, a pilot causes the rotors to rotate in synchronism by pedalling, then collectively increases the pitch of the blades of rotor 14 via lever 13 until sufficient lift is created (Fig. 5, not shown). Translational movement can be achieved by inclining the tip path plane of the rotor 14 via lever 12 and a linkage of rods (Fig. 4, not shown) which bodily tilt the rotor. The machine is steered by pitch change of the tail rotor 5 by means of a horizontally movable tiller 11 connected (Fig. 2, not shown) to a movable T-bar (29) on a plate (31) rigidly attached to the ariframe adjacent the tail rotor. The pedals 9 may as an alternative be manually operated by the pilot in the prone position, the levers 12, 13 then being converted to footoperated controls and the tiller 11 being incorporated into the pedal unit.

Abstract: 1,117,274. Control of A.C. motors. NATIONAL ACME CO. 24 Nov., 1965 [7 Jan., 1965], No. 49987/65. Heading H2J. [Also in Division B3] A drive for a rotatable pattern-supporting frame in a shell moulding machine comprises a three-phase reversible motor having high and low speed windings which is operated through a cycle by motor driven cam operated switches and limit switches controlling relay circuits. The frame is rotated through 180 degrees to meet an open topped investment box; the two then rotate together a further 180 degrees, thus inverting the box above the frame. Sand and a binder thereby fall on to the pattern which is heated and vibrated. Finally the motion is reversed to restore the parts to their original positions leaving a shell mould on the pattern. The speed cycle is as follows: high speed rotation of the frame 325 degrees; slow speed through a further 35 degrees; stopping by electromagnetic brake, applied when both motor windings are de-energized; pause while sand and binder fall to the pattern; slow reverse motion through 35 degrees; fast through 290 degrees; slow again for the final 35 degrees; stopping in the initial position by the electromagnetic brake. An oven is then lowered over the mould for a predetermined time by pneumatic means having an electromagnetic valve controlled by the cams. Each cycle is initiated by a manual push button. The circuit is fully described and illustrated.

Title: Propagation pattern for magnetic bubble domains
IPC: G11C11/14
Filed: 1974-11-20
Abstract: 1479019 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 20 Nov 1974 [27 Dec 1973] 50339/74 Heading H3B A propagation path for magnetic bubble domains is formed by a continuous pattern corresponding to bars in abutting relationship, alternate bars being of different thicknesses. The pattern may be a permalloy overlay on an orthoferrite or garnet layer 22 supporting bubble domains, Fig. 1, ion implanted or diffused regions of different depths in the layer, or grooves in the layer formed by etching to different depths. The pattern shown provides a plurality of bubble propagation channels, the central two channels identified by the repeated series of numbers 1 to 4 providing a closed loop circulating path. Each such number identifies the position in the pattern in which a bubble can be momentarily located in response to a clockwise in-plane rotating magnetic field. The propagation pattern consists of relatively thick H-shaped bar members 10 to 20 in contact with alternate bars 32 to 46 of a thinner dimension. A closed circulating store is obtained by the use of a relatively thick bar such as 52, 58, which abuts a thinner bar such as 46 positioned so as to bridge adjacent propagation channels, the higher field intensity of the thicker bar serving to turn the bubble movement. In the arrangement shown a clockwise in-plane field produces anticlockwise bubble circulation and vice versa. An overlay pattern may be produced by a deposition process.

Abstract: 1279640 Metallurgical furnaces ALLIS-CHALMERS MFG CO 23 Oct 1969 [1 Nov 1968] 51931/69 Heading F4B [Also in Division C7]  Mineral ore is agglomerated and fed to the drying zone 6 of a travelling grate to be dried by gases at a temperature of 500-900 F. passing down through the ore to windbox 8. In the succeeding zone 7 the ore is heated to 1600- 1800 F. by gases passing downwardly therethrough to windbox 9. The ore is then discharged via shoot 10 to kiln 12 in which it is heated to about 1800 F. by a countercurrent stream of reducing gases which effect some reduction in the ease of haematile ore of Fe 2 O 3  to FeO. The ore falls into a hopper 15 which feeds it on to an annular rotating gate furnace 17 on which it forms a layer overlying a layer of steel balls fed from hopper 29. In a first zone of the travel of the annular furnace the ore is reduced to a desired degree of metallization by hot reducing gases passing downwardly therethrough and in a second zone the reduced ore and steel balls are cooled by an upward stream of cool gas and are discharged through a sieve 70 to separate reduced ore from the steel balls, the latter being recycled to hopper 29. Fresh gas for the reduction is provided from a reformer 30 fed with a hydrocarbon gaseous fuel whose reducing gas product is mixed with recycle gas heated in heat exchanger 58 and passed to the reduction zone 27. The used gas passes through dust separator 38, condenser 40 for removal of water, and is divided into two streams, one passing through scrubber 53 for removal of CO 2 , through the hot steel balls and reduced ore in zone 28 to cool the ore and recuperate the heat therein, returning to heat exchanger 58 for recycling. The other stream is fed to rotary kiln 12 and preheating zone 7 in which, with supplementary fuel and air introduced at 75, 76 and 80, 81, 82 the preliminary reduction and preheating respectively are performed.

Abstract: 1436856 Limited-slip differential gear EATON CORP 8 Nov 1973 [8 Nov 1972] 51937/73 Heading F2D An input shaft 20 rotates a casing 11 through a cross shaft 21 which carries pinions 14 meshing with a side gear 12 connectible at 23 to the front wheels of a vehicle and a side gear 13 connectible by a shaft 33 to the rear wheels. An annulus at the rear face of the wheel 13 has cam surfaces coacting with a cam ring 52 so that when the wheel 13 rotates relatively to the casing, on differential action taking place, it tends to rotate the ring 52 with it, the cam surfaces being held in engagement by a wave spring 60. A weight 71 pivotally mounted at 72, 73 in the casing is provided with portions 78, 79 coacting with projections, 81 on the periphery of the ring 52 whereby rotation of the latter relatively to the casing causes the weight to be oscillated, and as the rate of such relative rotation increases the ring 52 is retarded by the oscillating weight so that it is moved by the cam surfaces axially away from the wheel 13 to engage a disc-pack clutch 40 thereby limiting the differential action. In a modification, a coil spring replaces the wave spring 60, the cross shaft 21 is formed with a central enlargement encircling the input shaft and splined thereto, and the weight is bored to receive bearings and a spindle on which it oscillates.

Title: Improvements in colour television receivers

Abstract: 1,076,890. Colour television. COMPAGNIE FRANCAISE DE TELEVISION. Dec. 22, 1964 [Dec. 27, 1963], No. 52169/64. Heading H4F. The invention relates to a receiver for use with a signal of the SECAM (Registered Trade Mark) type where the subcarrier is modulated in alternate lines by - (R-Y) and + (B-Y) and identification signals are transmitted during five lines of the vertical blanking interval in the form of trapezoidal waves which are positive during R-Y lines and negative during B-Y lines. The receiver reverses the polarity of the R-Y signal and utilizes a conventional delay line switch system to establish continuous trains of R-Y and B-Y signals in separate channels. With such an arrangement, trains of identification signals are also produced in the two channels, the signals being of negative polarity when the delay line switch system is operating in the correct phase relative to the corresponding transmitter switch and being of positive polarity when the switch system is operating in the incorrect phase. The identifying signals are utilized automatically to reset the delay line switch if operating in the incorrect phase, and in accordance with the invention this is done by deriving a control signal with the aid of a matrix circuit which combines the identifying signals from both colour channels. In one arrangement, Fig. 3 (not shown), the control signal controls a gate through which line synchronizing pulses pass to trigger the delay line switch and functions to close the gate and remove a pulse when the switch phase is incorrect. In another arrangement, Fig. 4 (not shown), provision is also made to utilize the absence of identifying signals in a non-colour signal, to blank off the colour stages. In this arrangement correction of the delay line switch in the event of incorrect phase of operation is achieved by adding a pulse to the line signal pulses which trigger the switch.
