Title: Root crop harvesters
IPC: A01D33/00
Filed: 1971-05-26
Abstract: 1410167 Root crop harvesters RANSOMES SIMS & JEFFERIES Ltd 25 Aug 1972 [26 May 1971] 17250/71 Heading A1F An electrically actuated device for controlling the lateral position of a crop lifting member of a root crop harvester has a pair of sensing arms which, in use, are biased into engagement with the ground on either side of at least one row of crop and arranged to close switches when, due to the lateral deflection of the lifting element and sensing arms, the movement of one of the arms upwardly onto the row exceeds a predetermined amount. The switches are connected in an electrical circuit that controls a means for realigning the lifting element with the crop row. In a first embodiment a pair of spring biased sensing arms 17 and 19 have respective micro switches 25, 27 which are connected to a solenoid operated valve so that fluid flows in the desired sense to a ram 11 when either of the two switches is closed by its associated arm. The consequential expansion or retraction of the ram 11 moves an arm 7 pivoted at its upper end to a hitch 3 and its lower end to a tow bar 9 and hence moves the harvester transversely and in such a direction as to realign the crop row with a pair of lifting wheels 13. The' micro switches 25, 27 are mounted in a support 29 so as to pivot about horizontal transverse axes and the support 29 can be adjusted by rotation about the same axes for varying the aperture between the arms and the operating members of the respective micro switches. A manual override switch (Fig. 4: not shown) is also included in the electrical circuit so that the ram 11 can be actuated independently of the micro switches for adjustment purposes. In an alternative embodiment, the ram 11 is replaced by an electric motor coupled to the tractor hitch via a rack and pinion and connected in an electrical circuit to the micro switches.  In a further embodiment the lifting element may be mounted on a sub frame of the harvester which is transversely moveable. A pair of lifting elements are provided in other embodiments for simultaneously working two adjacent rows and each lifting element has a pair of sensing arms.

Title: Time-delay transmission line
IPC: H03H7/34
Filed: 1946-06-06
Abstract: 606,550. Time-delay transmission lines. HAZELTINE CORPORATION. June 6,1946, No. 17252. Convention date, June 18, 1945. [Class 40 (viii)] A time-delay transmission line comprises an elongated conductive member, such as a core 10 and a winding 11 insulated from the core, but coupled thereto to provide a distributed capacitance, and a condenser bridged across a number of turns of the winding. The value of the condenser and the number of the turns is so chosen that, in response to an applied signal, a short pulse is superimposed on the delayed pulse output ahead of the leading edge of the delayed main pulse. The purpose of this is to smooth out by compensation the negative echo that would precede the pulse in the simple network without the condenser. The latter may comprise a ring 21 of polystyrene with a thin slotted, copper or silver coating 20, connected by a conductor 22 to the other end of the turns desired to be bridged. As normally there will be more than one negative echo it may be advantageous to use several bridging condensers each of which compensates for one echo. The construction shown is a three-terminal network, but four-terminal networks can be obtained by substituting a coil for the core 10. Specification 606,547 is referred to.

Title: Hydraulic apparatus for regulating the flow of one or more pumps
IPC: F04B49/08
Filed: 1970-04-15
Abstract: 1307914 Fluid pressure servomotor system C PENSA 15 April 1970 [23 April 1969] 17874/70 Heading G3P A hydraulic apparatus for regulating the flow of a pump 1 as a function of the hydraulic power generated by the pump comprises a member 9 which varies the flow and is moved by a motor means 20, wherein the motor means is driven by the pressure generated by the pump. The high pressure fluid in chamber 25 of cylinder 19 passes to a chamber 27 housing a piston 28 whose point of application on lever 29 varies with the position of the member 9. In the neutral position of a control valve 31, the connections from the low and high pressure lines 14,15 respectively are blocked by the spool. If the delivery pressure in line 15 increases the piston 27 moves against an adjustable spring 33 to rotate the lever 29 and raise the spool 31. The upper chamber 24 of the cylinder 19 is then in communication with the low pressure side of the pump and the high pressure fluid in chamber 25 drives the motor 20 to a position in which the force of piston 27 is again balanced by the spring 33. In an alternative arrangement Fig. 2, (not shown) a pressure reducing valve (39) provides a pressure in a duct (40) which is a function of the position of the motor 20. As applied to two pumps Fig. 3, (not shown) the arrangement provide a limit to the flow of pumps such that the sum of the powers delivered by them does not exceed this predetermined limit. The thrusts exerted by the levers (29) (29') act on the spool (46) to control the positive of the comman motor (51), and springs (61) (61') keep the members (9) (9') in the position of maximum flow compatible with the position of a rocker arm (56) of the motor (51). Each Spring is influenced by an associated motor (60) (60') driven in response to a deviation of the corresponding pump pressure from the average pump pressure.

Abstract: 141,006. Relay Automatic Telephone Co., (Assignees of Betulander, G. A.). April 2, 1919, [Convention date]. Automatic exchange systems. - Relates to switching-apparatus, particularly for automatic exchange telephone systems, in which sets of spring contacts for connecting incoming and outgoing lines are arranged in parallel rows and can be selectively operated electro-magnetically by selecting and operating members, of which the former selects, say, the vertical row containing the wanted set of contacts, while the latter operates that set of contacts which is in the horizontal row corresponding to the operating-member in question. In the arrangement shown, one hundred sets of contacts 1 are arranged in ten horizontal rows on shelves 2, the contact sets of the top and bottom rows only being shown in Fig. 1. The contacts of each horizontal row are actuated by a member 7 integral with the armature 8 of a magnet 9. Each set of contacts 1 has an operating-spring 16 having a stepped end 17 arranged above an aperture 18 in the operating-member 7. The magnet 9 only operates the contacts 1 if a selecting-member 13 is moved across the aperture 18 so as to couple the parts 7, 16. The selecting-members 13 of springy magnetic material are mounted on vertical bars 12 and carry armatures 15 co-operating with the extended polepieces 10 of the magnets 11. The bars 12 form extended pole-pieces of the magnets 19, and are connected by non-magntic material 20 to the bars 10. To operate a set of contacts, a pair of magnets 11, 19 is first energized, the extended polepiece 10 attracting all the armatures 15 and selecting-members 13 corresponding to the selected vertical row. The energization of a magnet 9 corresponding to the desired horizontal row then causes the member 7 to operate the set of contacts in that row determined by the selecting- member 13.

The servomotor 40 for varying the capacity of pump 10 is connected via a changeover valve 31 to the high pressure line 13 or 14, and relief valves 35 and 36 are also provided between the main lines 13, 14 (via lines 30 and 32). In operation the valve 17 is moved to positions I or III by the pressure in a main line 13 or 14 (acting through lines 42 and 43) to thereby connect the low pressure line to the reservoir, the feed pump 12 making up the loss and the single pressure maintaining valve 18 acts for both pump 12 and valve 17. The pump 10 displacement is varied by main line pressure acting on the servo 40 through change-over valve 31. In overrun, with motor 15 driving pump 10, the change-over valve 31 is moved over and the pressure from the pump 12 sets the pump 10 to a higher delivery rate.

Title: Improvements in or relating to foot operated player instruments
Filed: 1926-07-21
Abstract: 279,169. Hauser, A. July 21, 1926. Blowing and exhausting air; treadle devices.- A foot-treadle drive for the bellows of a pneumatic player instrument having expression-controlling means, co-operates with power-equalizing means exhausting at first large volumes of lowtension air and building up and maintaining a high vacuum or air pressure, thus ensuring a uniformly low resistance to operation of the treadles. In Fig. 1, mechanical means is employed. The treadle 3 is connected by pivoted links 33, 12 to a bell-crank 10, 9 connected by a link 13 to the lower end of the movable leaf 1 of the exhaust bellows. A link 7 connects the movable leaf 2 of the associated reservoir bellows to a link 6 which is pivoted at 29 to a fixed point and at 36 to a link 11 in turn pivoted at 38 to the links 33, 12. As the tension increases, the reservoir 2 gradually collapses and the link 11 approaches the link 12, thereby diminishing the stroke of the bellows 1. A lever 21 is operated by the leaf 2, and operates an indicator device by a rod 20, when maximum vacuum exists in the reservoir. In Fig. 6, a main bellows 68 for high-tension work is mounted on the movable leaf 200 of a larger auxiliary bellows 100. At first, greater quantities of low-tension air are exhausted by the large bellows only, the leaf 68 remaining collapsed on and moving with, the leaf 200. As the air tension increases, a valve 70 controlled by spring 81 of predetermined tension, opens, and the smaller bellows 68 takes over an increasing amount of the work. A spring 82 prevents bellows 100 from collapsing entirely, and at high tension a lug 71 assists in opening the valve 70. In Fig. 7, a larger and a smaller bellows 84, 84<a> are connected by a bar 92 and operated together to exhaust air through valves 91, 91<a> from a reservoir 85. As the air tension increases, reservoir 85 collapses, releasing the tension of the spring 86 of an atmosphere valve (closed at low air tensions) on the larger bellows 84, allowing the valve to open more and more at each pedal stroke, and rendering the bellows 84 increasingly ineffective.
