The crop exiting through the opening is picked up by the next pair of the flails, as the shredder advances. This arrangement helps to ensure that the crop is finely chopped and prevent dirt and mud from clogging the shredder. Four sets of flails 18 are pivotally mounted on transverse bars 17 carried on stub shafts 16 which extend radially from a rotor 15. Fan blades 36 arranged to generate a radial or axial air current may be mounted on the bars 17 so as to separate the flails 18. A deflector tray in the form of a hood 27 may be pivotally mounted from the housing 23 to control the distribution of the chopped crop. The angle of the hood 27 is set by means of an hydraulic actuator 29 operable from the cab of a towing tractor. Fixed deflector plates arranged to spread the crop outwardly relative to the rear of the shredder are provided on the hood 27.

Title: Method and apparatus for locating targets
IPC: G01S3/787
Filed: 1960-12-19
Abstract: 1293751 Optical position finding ELTRO GmbH & CO 19 Dec 1960 [18 Dec 1959] 43674/60 Heading H4D A method of locating a target by forming-an image of the target and determining the polar co-ordinates of the image with respect to an axis, which method comprises deriving a signal in accordance with the presence of the image, generating first and second reference signals each of predetermined frequency and phase, periodically interrupting the image so that the derived signal is a modulated signal having two components whose respective frequencies are the same as those of the reference signals and whose phases relative thereto are functions of the respective polar co-ordinates of the image' with respect to said axis, and comparing said components respectively with said reference signals. The apparatus for carrying out the method includes an optical system for examining the target area and forming an image of the target in the plane of a rotating disc 30, the polar co-ordinates P, # of the target image being measured with reference to the disc centre and the O-co-ordinat Fig. 4a. One half of the disc 30 is formed with curved apertures 38 whereby the target image may be received by a detector placed behind the disc and connected to a phase comparator where the signal is compared with a reference signal. The reference signal I, Fig. 6a, is generated by a generator running in synchronism with the rotating disc. A target displaced at an angle #begins to produce a signal when the disc 30 has rotated through the angle # in the direction of the arrow so that the first aperture is aligned with the target image, the target signal being denoted by II and shown in Fig. 6b. Thus by measuring the displacement #, Fig. 6b, the polar co-ordinate # is directly determined. The target signal II extends through a rotation # and is divided into 2<SP>n</SP> subpulses by the apertures 38 and webs 36. As shown, n=3 and the curvature of the webs is such that their peripheral extremities are displaced by an amount equal to their maximum width so that through the extent of the disc radius the phase of modulation changes by it s  half-period. In order to determine the polar co-ordinate p a sine wave III, Fig. 6c, is generated from the recurring pulse II and from signal III a signal IV, Fig. 6d, is derived by frequency multiplication, the multiplication factor being equal to 2<SP>n</SP>. From signal II a sine wave signal V, Fig. 6e, is derived. The signals IV and V are of the same amplitude and frequency but are phase shifted relatively to one another in dependence upon the co-ordinate p. To measure co-ordinate p signals IV and V are added to produce signal VI, Fig. 6f, the addition being such that for p = 0 the signals are in anti-phase and cancel one another out. Thus the amplitude of signal VI determines the co-ordinate p.

In the transfer region, the pusher members 4 disengage from the dogs 5, the dogs 6 being displaceable into and out of the path of the pusher members 4 by means of a cam 14, but outside a transfer region, the dogs 6 are disposed out of the path of movement of the pusher members 4. Each dog 6 is guided for vertical movement in its associated trolley 2 by two horizontal transverse pins 7 and side plates 10 of trolleys 2, and carries at its upper end sliding cam followers 19 which co-operate with cams 14 fixed to and extending along the tops of the channels 3 in the transfer region. A ramp 13 co-operates with a projection 16 from a trolley 1 to lower the associated driving dog 5 out of the path of movement of pusher members 4 if a trolley 1 runs into a trolley 2. Each trolley 1 has a forward holdback dog 21 which can pivot forwardly under the action of a pusher member 4 and engage with the associated forward driving dog 5 but cannot be pivoted rearwardly from that position. Each dog 5 has its top surface shaped so that it can pass forwardly below a pusher member 4 but the pusher member 4 cannot pass forwardly over it. Each dog 5 is guided for vertical displacement in the associated trolley 1. At the lower end of the dog 5 are two transverse pins 23 which constrain this end of the dog 5 and one end of a lever 24 to move with each other. Projecting rearwardly from each dog 5 and fixed thereto is an arm 25 which overlies a forwardly projecting arm 26 fixed to the associated dog 21. When a dog 5 is displaced downwardly, the associated arm 26 is displaced downwardly by its associated arm 25 so that the associated dog 21 is pivoted against a counterweight 27 so that the dog 21 does not project into the path of movement of members 4. In order to ensure that this occurs in a transfer region, each lever 24 has fixed thereto a cam follower pin which co-operates with a cam 29 fixed to one of the channels 3.
