Title: Haymaking machines
IPC: A01D78/10
Filed: 1972-11-03
Abstract: 1412988 Hayraking machine C VAN DER LELY NV 3 Nov 1972 [5 Nov 1971] 50895/72 Heading A1F A hayraking machine has two rake wheels carrying tine assemblies which move automatically from the transport position to the working position by centrifugal force. At the end of each spoke 27 is a housing 30 supporting a shaft 34 carrying the counter balanced tine assembly and a shaft 35 covering an offset weight 45 which swings outwards as the rake wheel rotates. As it does, a friction or serrated drive between an annulus 44 and a wheel 43 causes the tines to move into the working position. Rotation of the plate 50 relative to the shaft 52 sets up axial movement of each link 49 causing rotation of each housing 30 about its shaft 33. Attached to the shaft 52 is a bracket with a spring pin 53 which can enter either of two holes in the plate 50 thus providing a choice of two angular positions for the tines about the shaft 33. In another embodiment, Fig. 4 (not shown) the weight runs in a parallelsided slot and is connected to the tine assembly by pivotting links. In a further embodiment, Figs. 5 and 6 (not shown), rotation of the tine assembly is caused by the weight of a ball moving under the combined effect of gravity and centrifugal force along a cylinder attached at one end to the pivot shaft and at right angles to it. In a further embodiment, Fig. 7 (not shown) a lever on the tine assembly pivot is attached by a link to a double bell crank carrying the weight which moves to a lower position under gravity and an upper position under centrifugal force.

Abstract: 1,191,170. Braiding-machines. S. ICHIKAWA. 10 Nov., 1967 [ill Nov., 1966], No. 51376/67. Heading D1C. Bobbin carriers C are prevented from rotating about their axes by a ring 3 rotating eccentrically below the horndog 7 and engaging the carrier so that it rotates relative to the horndog. The ring 3 is freely pivoted on the horngear 1 by links 2 and is maintained in its eccentric position by engagement with wheels 6. Projections 5 on arms 4 engage a notched disc 10 fixed to the carrier. During rotation of the horngear the carrier is thereby rotated a similar extent in the opposite direction to prevent twisting of the threads. The carriers are entrained .on the horndogs by a projection (.15 Fig. 5 not shown) which is released when a carrier is to be transferred, by a cam track (12) and follower (19) arrangement mounted above the dog.

Abstract: 1477451 Transistor bi-stable circuits GENERAL DYNAMICS CORP 21 Nov 1966 52125/66 Heading H3T [Also in Division B7] A switching amplifier 62 is driven by a Schmitt trigger 61 and powered by a battery 63. During one half-cycle of a dither signal when the output stage of Schmitt trigger 61 is in the cut-off state, transistor 67 will be cut-off causing transistors 73, 74 to be cut-off and transistors 72, 75 to be saturated, i.e. in a highly conductive state. With transistor 67 cut-off, diode 71 is reverse biased and blocks the base voltage of transistor 72, thus allowing transistor 74 to be cut-off. Additionally, clamping network transistor 99 clamps the base 96 of transistor 74 to ground during this half-cycle and prevents inadvertent activation of transistor 74 due to leakage current. This condition causes current to flow from terminal 79 to terminal 78 through a torque motor 41. During the other half-cycle of dither signal, when the output stage of Schmitt trigger 61 is saturated, transistor 67 is also saturated. With transistor 67 now turned on, diode 71 conducts and develops a voltage for base 94 of transistor 72 which is more negative than that of emitter 87, thus causing transistors 72, 75 to be cut-off. At the same time, transistor 99 is turned off, removing its clamping effect, and transistors 73, 74 become saturated. This condition causes current to flow from terminal 78 to terminal 79 through torque motor 41, resulting in rotation in the opposite direction.

Photographic apparatus comprises the combination of a flash apparatus 1 having a photo-cell 4 associated with control device 3 for determining the duration of the flash from a lamp 2, and a camera 6 having a photo-cell 11 therein receiving light through the camera lens 7 and a semi reflecting mirror 9, each of the cells 4, 11 being connectable, via changeover switches 15, 16 and contacts 17, 18 respectively, with the device 3 for flash duration selection. When photographs are taken with the flash apparatus, plug contacts 5, 13 are inserted in the apparatus 1 and the camera 6, so as to connect the cell 11 with the device 3 and disconnect the cell 4 from circuit therewith. The cell 4 is provided with a removable filter 14 the transmittance of which corresponds to camera lens 7 and mirror 9. The cell 4 ensures that the control device 3 can be used independently of the camera 6, if desired. The arrangement provides for the use of the flash apparatus at a distance from the camera, but giving correct exposure of film in the camera. In a modification, (not shown), an electrical damping resistance is used connected in series with the photo-cell 4 for balancing out the difference in illumination between the use of directly illuminated photo-cell 4 of the flash apparatus, on the one hand, and the use of the photo-electric cell 11 mounted in the alternated path of the taking rays, on the other.

Abstract: 1,165,186. Clutch/brake units; disc brakes. INDIVE G.m.b.H. 1 Dec., 1966, No. 53917/66. Headings F2E and F2L. [Also in Division H2] The invention provides a squirrel-cage motor driving, e.g., a laundry spin dryer or a centrifuge on a vertical axis; the motor is associated with a mechanical brake; and the induced rotor field holds up, during running, a magnetic axially-movable member to prevent the brake being applied. As shown, the mechanism provides, in effect, three clutches between, on the one hand, the rotor and its shaft and, on the other hand, the brake. The parts are shown in the positions they occupy while the motor is running. An end ring 12 of the squirrel cage is accommodated in a U-section yoke M of magnetic material which has apertures at 15, opposite the rotor grooves, through which the bars 13 extend, the cage being a one-piece aluminium casting. The induced field is effective, even during running at maximum speed, to retain an axiallymovable annular body 21, of magnetic material, in contact with the yoke M against the force of a helical compression spring 22 which is anchored to the rotor 11 and may be anchored to the body 21. Other clutch parts comprise a sleeve 41 with conical top 411, a helical spring 44 anchored at its top to sleeve 41, a coupling member 43 loose on the rotor shaft 10 and having a flange 43<SP>1</SP>-these parts being stationary while the motor is running-and finally another coupling member 42 keyed to the rotor shaft 10 and spaced from spring 44. The brake is constituted by the rotatable flange 43<SP>1</SP>, lying between friction surfaces located on a stationary disc 31 adjustably loaded by springs 33 and on the end of the motor casing. In operation, when the motor current is switched off, the body 21, which is not connected with shaft 10, is pushed downwards by the spring 22 and, still rotating, it makes contact with sleeve 41. The now-rotating sleeve 41 winds the spring 44 so that it frictionally couples the members 42, 43, so that member 43 rotates. Member 43 is braked by the friction surfaces acting on its flange 43<SP>1</SP> whereby, through spring 44 and member 42, the shaft 10 and rotor 11 are brought to rest. (Thereafter, the resilience of springs 44 and 22 permits limited rotation, in both directions of the dryer or centrifuge.)
