Title: Hay making machines
IPC: A01D78/12
Filed: 1972-12-15
Abstract: 1417420 Haymaking machine C VAN DER LELY NV 15 Dec 1972 [15 Dec 1971] 58166/ 72 Heading A1F A haymaking machine comprises a frame 6 to 9 and at least one rake member that is rotatable relative to the frame about an upright axis 1 and has groups of tines 3 turnable about axes 18 of shaft-like members 19, inclined to and radially spaced from the axis 1, each of which is supported on the remainder of the rake member at only a single location at only one end of the shaftlike member, the opposite free end being closer to the axis of rotation than is said one end. The members 19 are formed by the cranked ends of spokes 2 which radiate from a hub 4. Rotation of the tines around the axes 18 is affected by control rods 5 lying alongside the spokes 2. The control rods 5 are actuated by a lever mechanism (Fig. 6) housed in the hub 4, so that the tines generally adopt a radial disposition except at, at least, one circumferential position R where a lever 60 engages a wheel 37 which draws the control rod towards the hub so retracting the group of tines concerned into a tangential disposition pointing rearwardly of the direction of rotation B of the rake member. As the group of tines moves on to positions S and T in Fig. 6 centrifugal force draws the tines back to their radial disposition allowing a lever 59 to lock the tines in that disposition, by virtue of springs 65, until they reach position Q where a stop plate 67 is engaged by a control arm 58 associated with the lever 59, releasing the lock to permit retraction of the tines on reaching position R.  At slow speeds the hay falls from the tines when in position R forming a swath on the left, in the case of the embodiment of Fig. 1, of the rake member. At higher speeds at least one swath board may be employed to assist in forming the swath.

Title: Self-cleaning ovens
IPC: F24C15/32
Filed: 1971-12-15
Abstract: 1327366 Releasable fastenings; door operating mechanism ANETSBERGER BROS Inc 15 Dec 1971 [16 Dec 1970] 58242/71 Headings E2A and E2M [Also in Divisions F1 and F4] The doors of a self cleaning oven are hinged at their outer edges on pintles 57, which carry sprockets 58 engaging chains 59. The inner part of the chain of each door is connected to the outer part of the chain of the other door by inner links 62, outer links 61 and adjustable bolts 63, Fig. 7. A plate 64 depends from each inner link 62 and is connected to the frame of the oven by a spring 65, so that open- - ing one door causes the other door to open. A cam disc 66 is mounted at the lower end of each pintle 59 and has notches engaging a pin or roller 71 on a lever 72 pivotally mounted on the frame of the oven and a spring 74 urges the pin 71 into the notches on cam disc 66 that the doors are releasably held in a closed, fully open or partly open position, and are urged to a fully closed position when they are nearly closed manually. A keeper 75 connected through linkage 77, 78 to a solenoid 79 is swung to engage a stud 76 to prevent the doors being opened when the solenoid 79 is energised, by the operation of a control to initiate a heat cleaning operation. A thermostat within the oven de-energises the solenoid 79 only when the temperature falls below 580F.

Title: Video signal phase regulating systems
IPC: H04N5/92
Filed: 1971-12-22
Abstract: 1347924 Automatic phase control; pulse delay circuits SONY CORP 22 Dec 1971 [22 Dec 1970] 59783/71 Headings H3A and H3P A video signal phase regulating system comprises: means for deriving from the video signal two phase-displaced angle-modulated signals P<SP>1</SP> 1 , P<SP>1</SP> 2  frequency separated from the video signal: a variable delay means, 12a or 12b connected in at least one of the derived signal paths: means 8 for recombining the derived signals: means 13 for sampling the recombined signal, or a signal derived therefrom, to provide an error signal when the phasedisplacement varies from a predetermined value: and means for adjusting the variable delay means in dependence on the error signal. As described the two signals P<SP>1</SP> 1 , P<SP>1</SP> 2  are nominally quadrature pulse signals at half the video frequency and are derived from a video tape (not shown). Both signals are fed via respective pulse delay circuits 12a, 12b to a multiplier 8 which provides the reconstituted video. A sampler 13 receives the output from 8 at its signal input, and sync. pulses, from the detected video, are derived by sync. separator 14 for application to the gating input. The resulting output signal, having a magnitude dependent on the deviation from quadrature of the two derived signals, is fed via bandpass filter 15, rectifier 16, low pass filter 17 to an amplifier 18 which provides differential control signals for the two delays 12a, 12b. In a modification, Fig. 7 (not shown), the sampler 13 samples the carrier leak component of the detected video signal. Pulse delay circuits, Fig. 4.-Pulses to be delayed are differentiated at 19, rectified at 20, and resulting pulses are used to trigger a monostable 21. The leading edge of the output pulse triggers ramp circuit 22 to produce a sawtooth which is terminated by the trailing edge of the pulse after differentiation by 23. The resulting sawtooth signal is fed to a variable threshold Schmitt trigger 25 to produce trigger pulses for a 1-bit counter 26, the trigger pulses occurring at a time determined by the threshold setting of the trigger 25. The counter 26 is reset by further pulses from differentiator 19, and produces an output corresponding to a delayed version of the input signal.

Patent GB-608782-A (GB)
Abstract: 608,782. Gyroscopic apparatus. JACK & HEINTZ, Inc. Jan. 16, 1946, No. 1488. Convention date, Feb. 24, 1945. [Class 97 (iii)] In a gyroscopic artificial horizon for aircraft, a guide track 26 carried by the rotor casing 11 co-operates with a bearing assembly 27 supporting a pin 24 of an arm 23 on the spindle 18 which pivotally supports the horizon bar 16 on the gimbal ring 7. The guide track is substantially circular, but with an inwardly extending eccentric portion which engages the assembly 27 when the horizon bar is in its central position. When the ring 7 rotates around the transverse axis 8, 9, the horizon bar first moves to the edge of the dial as the assembly 27 moves to the end of the eccentric part of the track. Thereafter the horizon bar remains stationary whilst the assembly 27 runs in the circular part of the track and is only moved towards the centre of the dial when th assembly 27 again reaches the eccentric part o the track.

Patent GB-2001220-A (GB)
Title: Controlling and/or regulating level of useful sound
IPC: G10L21/034
Filed: 1978-07-12
Abstract: A process and apparatus for controlling and/or regulating a source of useful sound, e.g. a car radio, in a sound field affected by sonic interference measures the interference level separately from the useful sound level and controls and/or regulates the useful sound output so that it increases whenever the measured interference level increases. "Control" implies that the useful sound level is determined by the corresponding measured interference level in conformity with a predetermined relationship of the characteristic-curve type. "Regulation" implies that a signal magnitude is derived from the measured interference level, the useful sound level is also measured and compared with the signal magnitude, and the useful sound level is then adjusted on the basis of the comparison between the required and actual signal magnitudes. <IMAGE>

Title: Cluster bombs
Inventor: WHEATON GEOFFREY BRENDAN
IPC: F42B12/62
Filed: 1980-01-03
Abstract: A cluster bomb in which a canister 1 contains a multiplicity of sub-munitions 34 guided in tubes 28 to be projected forwardly from the canister following separation of a nose 2 and deployment of a parachute tail 24 which retards the canister relative to the submunitions. A lanyard (19) extending from an aircraft serves both to activate a fuse associated with separation means for the nose 2 and to deploy the parachute. The projected sub-munitions are armed as a plate 39 is drawn rearwards by the drag of the air, the arming being delayed by engagement of a pin in a zig-zag groove 41. Fins 35 and grooves 36,37 in the submunitions contribute to aerodynamic instability of the submunitions so as to assist their spreading out over a wide area. <IMAGE>
