Title: Improvements in or relating to an automatically openable gate or the like
IPC: E05F13/04
Filed: 1959-07-31
Abstract: 916,872. Gate-operating appliances. KOCSIS, F. July 28, 1960 [July 31, 1959], No. 26432/59. Class 65 (1). A gate or the like has an extended rod 1 along its inner edge with a roller 5 on an arm 4 and a segmental plate 7 situated at its lower end and rotates about an axis provided by pins 9, 10 upon which it is also allowed to move axially. The passage of a vehicle over either of the road pads 25, 26 moves a cable 23, 24 so that a mechanical apparatus is actuated to raise the lower end of the curved strip 12 upon which the roller 5 runs so that the, weight of the gate causes the roller to run along the track 12 and thus open the gate; the opening is assisted by a cord hinged around the segment 7 and connected to the apparatus so that it raises the strip 12. When the gate is open it is engaged by a stop device that holds it open for a predetermined time before allowing it to close. The strip 12 is raised by a ball-crank lever 13, 20 which is connected either directly or indirectly with the cables 23, 24; in other embodiments described, the position of the bell-crank lever is varied (Figs. 7, 12, 18, not shown). The stop device comprises a spring- loaded dashpot which may be connected to a ratchet that engages the end of the arm 4 (Fig. 6), or to a U-shaped lever that engages either the lower edge of the gate or the arm 4 (Figs. 5, 13, not shown), or to a stepped lever that can fit under the strip 12 (Figs. 17, 19, not shown), the dashpot releasing the ratchet &c., after a predetermined time to allow the gate to close. The treadle may be a simple plate-like member pivoted to a frame along one edge; alternative forms of treadle are illustrated in Figs. 8-10 and 14-16 (not shown) and are described and claimed in Specification 916,873. When two gates are used the mechanism shown in Figs. 2 and 3 may be connected with a similar mechanism to open the other gate, or the two gates may be connected by a crossed cable to open simultaneously.

Abstract: 1463695 Height adjustment of groundworking implements DEERE & CO 19 June 1974 [21 June 1973] 27235/74 Heading A1B [Also in Division F2] A disc harrow having vertically adjustable ground wheels 78, 82, Fig. 2, pivoted to respective transverse rockshafts 64, 66 movable by hydraulic ram 90 via respective brackets 88, 86 also has a pivoted front hitch structure 96 and a harrow frame levelling linkage 130, 118, 150, 154 connected between the hitch and the rockshaft 64. The levelling linkage comprises a lever 118 centrally pivoted to the frame and endwise pivoted to an adjustable spring hitch link 130 and a fore-and-aft link 150. The rear end of link 150 is slidable in a tube 154 and both are slidable in a transverse trunnion 144, Fig. 4, which is fixed between brackets 146 on rockshaft 64. An adjustable spring 160 biases the link 150 to the rear and causes an abutment 122 on the lever 118 to firmly engage against the frame in the transport position shown. During operation the harrow is adjusted in its transport position by first ensuring sufficient bias in the spring 160 to maintain contact between the abutment 122 and the harrow frame. The length of the link 130 is then adjusted until the frame is level. After placing the harrow in its operating position by retracting ram 90 the spring 160 is adjusted until uniform soil penetration is achieved. The abutment 122 is free of the frame. The arrangement is such that the spring 160 increasingly urges the hitch downwardly as the wheels are lowered to the transport position and such that the frame arrests the linkage motion before the wheels are fully lowered. When the wheels are fully lowered the spring 160 is thereby prestressed such that the linkage is rigid to shocks. The disc gangs 40 are longitudinally adjustable on the frame.

Title: Improvements in electric distant control systems for repeating angular movements
IPC: G08C19/38
Filed: 1937-10-11
Abstract: 503,425. Electric control systems. PESTARINI, G. M. Oct. 11, 1937, No. 27588. [Class 40 (i)] In an electric distant control system for reproducing angular movements, the transmitter comprises a commutator machine which transforms a constant direct current into polyphase currents having fixed and variable frequency components, the fixed component being produced by rotation of the armature and the variable component, which represents the movement to be transmitted, being produced by the commutator brushes; alternatively both components may be derived from the movement of the brushes. As shown, the system is adapted to reproduce the resultant movement of transmitters A, C. The primary transmitter A comprises a commutator armature 1 located within a laminated iron ring 3 and driven by a synchronous motor 2 fed by a polyphase line L. Brushes 5, 6 movable by the transmitter index 10 and fed from direct constant current mains N co-operate with the commutator, the arrangement being such that the frequency of the polyphase output of the armature, which is tapped by the slip-rings 7, 8, 9 is modified in accordance with the movements of the brushes 5, 6. The output is applied to the movable brushes 37, 38, 39 of the second transmitter C which comprises a similar armature and stator 31, 33 adapted to produce a polyphase output in the leads 17, 18, 19 connected to the wound stator 13 of the receiver B. The rotor winding of the receiver is connected to a commutator and is supplied from the mains N through a pair of brushes 15, 16 which are continuously rotated by a synchronous motor 12, the arrangement being such that the rotor 11 is moved through an angle equal to the sum of the movements of the brushes of the transmitters. If desired, the armature of the transmitter C may be continuously rotated, the leads 17. 18, 19 then being connected to a further set of brushes on the commutator. In a further modification, the transmitter armature is stationary and the commutator brushes are continuously rotated by a synchronous motor, the stator of which may be adjusted in accordance with the movements to be transmitted.
