Abstract: A roller for crumbling soil has round support plates arranged at spaced apart intervals along the axis of rotation of the roller. The plates are profiled with a saw-tooth configuration having folds and projections. Elongated elements, preferably bars, are fixed to the projections to extend generally parallel to the axis of rotation. The elements are T-shaped in cross section with the crossbar and upright of each T being connected to the peripheries of the plates leaving a space. The roller can be assembled by securing cross struts to the end plates, and passing the struts through the spaces. The intermediate plates are loosely held in position with the struts that bear on the peripheries of those plates. Thereafter, the bars can be welded or otherwise fixed to the plates' peripheries.

Abstract: A drive transmission for a soil working implement includes spaced apart elongated tined beams that extend horizontally transverse to the direction of implement travel. The beams are driven to move vertically and horizontally through generally circular paths so that the tines are raised and lowered while moving laterally of the travel direction. A driving shaft and a driven shaft are spaced apart and extend perpendicular to the beams and above same. Each shaft mounts a respective eccentric disc that is fixed to each beam and an imput is connected to rotate the driving shaft which, in turn, rotates the driven shaft via the eccentric discs. The beams are connected to be displaced out-of-phase to mitigate vibration.

Abstract: An agricultural type tractor with lifting devices on the front, rear and both sides for agricultural implements. Each pair of rear drivable wheels which are in tandem pivot about a common axle and each pivotable pair of such wheels is driven by a separate hydraulic motor, with each motor, however, connected to a common control whereby the velocity of the wheels on one side can be increased while the velocity of those on the other is decreased for steering around curves and the like. The arrangement also provides a hydraulically lockable differential to avoid the spinning of one set of the drivable wheels while the other set does not move due to an obstruction or the like. Outboard of each set of drivable wheels is a rotatable supporting element which is mounted from the tractor's frame so as to be displaceable outwardly and upwardly relative to the adjacent 0010 set of drivable wheels. Each supporting element has two wheel members which receive an endless chain tread.

Abstract: A refuse collection device comprises a refuse inlet for connection to a suction duct of a refuse collecting container mounted on a vehicle. Resilient elements surround the periphery of the refuse inlet and form a seal between the refuse inlet and a surface over which the inlet is travelling. A roller froms one of the resilient elements and is mounted across a front portion of the periphery of the refuse inlet. The roller has a resilient surface which deforms to allow objects to pass beneath the roller without reducing substantially the seal provided by the roller.

Abstract: A cultivating implement has rows of tined soil working members that are freely rotatable about upwardly extending shafts. Each soil working member has tines positioned around the shaft which defines its axis of rotation. At the lower end of the shaft, a channelled feed member is attached and the shaft is hollow. Material from a container is dispensed from the container through the shaft and the feed member via a port to the ground being worked by the tines. The feed member is elongated and extends down, generally parallel to the tines of the corresponding soil working member which are mounted on circular plate supports. A further soil working member, preferably a supporting roller, is mounted behind the rows of soil working members.

Abstract: A tractor which is towing two agricultural implements extending transversely relative to the longitudinal axis of the tractor and having a width which is substantially greater than that of the tractor's width, the two implements being coupled to the tractor in tandem. The interior of the tractor's cab has a convex (as seen by the driver) mirror which extends almost completely across the interior of the glassed-in cab of the tractor so as not to block the driver's forward vision, whereby the driver can observe in the mirror both implements across their entire widths as well as the device for coupling both implements to the tractor. In a modification, the convex mirror is of less width (about one-half of the width of the cab) and is flanked by further mirrors on each side which reflect from still further mirrors mounted on the overhead of the cab to provide an increased lateral area which is within the vision of the driver through the mirrors.

Abstract: A hay machine for working crop lying on the ground, such as a side-delivery rake, a tedder or a combined hay-making machine has a tined carrier for redepositing worked crop on the ground and comprises rows of tines which, in operation, are rotated in a forward direction while being turned oppositely over at least part of their path near the ground. The tines, which are located near the ground, extend horizontally and in a forward direction with respect to the direction of machine movement. The carrier preferably mounts three rows of elongated tines that are each shaped as a lazy S and pointed at each end. A sun wheel and planet gear system drives the carrier as a whole while turning the tines to pick up crop, raise and deposit same to the rear of the carrier. The orientation of the tines can be adjusted by displacing the sun wheel relative to the frame and fixing same in position.

Abstract: The invention provides compositions which have a slimming and anti-cellulitis action when applied to the body, topically with massage or using trans-cutaneous electrophoresis. The compositions contain, in combination, a thioether and a xanthine derivative.

Abstract: A milker has a lower base with a concave bottom and a lower exit under vacuum that can be closed by a float with valve until the milk level pivots and/or raises the float to open the exit. An enclosure body is fitted on the base and includes a main vacuum inlet and a milk inlet nipple positioned and angled to direct milk inflow at the side and/or below the float. An enclosure cap is releasably fitted on the top of the enclosure body and mounts an air valve, pulsation nipples and a further vacuum inlet. A central stem from the bottom extends up through a central passageway in the float and also through the cap to afford a fulcrum or support for an arm that pivots or slides to close the main vacuum inlet when the air valve is opened. The float can pivot and rise to a limited extent when milking or when the milker is inverted for washing. The assembled cap, enclosure body and base are interfitted and sealed when the inlets and milk outlet are in alignment.

Abstract: A soil cultivating implement has a row of pivotable soil working members linked to a transverse beam of the frame and individual eccentrics are connected to the members to raise and lower soil engaging portions thereof. The portions are pivoted so that the rear parts thereof move through greater amplitudes than front parts of the portions. The frame can be supported by ground wheels which in transport position elevate the soil working members above the ground and this can be accomplished with hydraulic assemblies. The front of the frame can have a resilient coupling to a prime mover to reduce shocks induced by the eccentric drives. Dispensing mechanisms can be positioned to the rear of the soil working members to dispense and/or seed the worked ground.

Abstract: A supporting grid system for installation under a stage ceiling which includes a plurality of struts suspended from the stage ceiling. Each strut has a centrally vertically disposed I-beam portion and a pair of spaced-apart upper arms extending upwardly and outwardly from the upper aspect of the central portion and a further pair of spaced-apart lower arms extending downwardly and outwardly from the central portion. Both pairs of arms define cruciform-shaped grooves, such grooves being identical but opposed. The strut is integral and formed from extruded aluminum. It is normally secured in place by hanger rods connected to the ceiling of the stage through support members having a horizontal flange and a support part of cruciform-shaped cross-section to mate with and be received slideably within the cruciform-shaped groove defined at the top of the strut.

Abstract: A soil working machine, such as a cultivator, has a frame beam to which a working element is connected by a support. The support is resilient or resiliently mounted and can deflect when the working element meets an obstruction, or heavy ground resistance, but the working element maintains its orientation in the soil. A control rod coextends with the support and four pivot points enable the element to be displaced without loosing its orientation. The working element is pivotally connected to the support by a pivot pin and the control arm also can be pivoted to that element. In a variant, the control arm is eliminated and a V-shaped share is hinged to pivot up and down between stops.

Abstract: A soil working machine pivotably mounts at least one rotor having serrated working elements. The rotor is pivotally connected at each end to a frame beam by a pin which can be inserted into either one of two holes located one above the other. The hole chosen governs the resistance to upward pivoting of the rotor. The machine can be hitched to a tractor either with the frame beam substantially transverse of the intended direction of operative travel, or with the frame beam inclined to this direction. Each rotor has end plates that mount forward blades and the outer plate supports a gear transmission to the rear of the respective blade.

Abstract: A torque converter has a housing for an input shaft and output shaft drivenly connected to one another with friction elements rotatably mounted on arms on pivotable holders. The holders are interconnected by the members so that rotation of the input shaft rotates its holder and, via the tie members, the output holder. The friction elements are thus flung outwardly into contact with annular control members within the housing on which they roll. The friction elements also abut and roll on one another, so that at least a major proportion of axial forces on the friction element in operation are held in equilibrium by the elements themselves. Rotation of the friction elements is transferred to the output shaft by planetary gearing on a common axis for the input and output shafts and on the rotation axes of the elements. The transmission ratio is varied by moving a control member towards and away from a second control member which changes the circumference of the path over which the elements roll.

Abstract: Apparatus for analyzing components in a mixture by the steps of introducing the mixture into the ion source of a mass spectrometer, ionizing some of the individual molecules representative of the mixture, using the mass spectrometer to select a beam of ions of a single ion mass which may be characteristic of a target compound in the mixture, passing the resultant single-mass beam of ions through a gas-filled collision chamber, and then, using a second mass spectrometer, determining the mass spectrum of the collision fragment ions to confirm the identity of the target compound, and by measuring the intensity of all or part of the mass spectrum, determine its concentration or amount in the original sample mixture. The same apparatus is suitable for fundamental measurements of the collision processes, which in addition to fragmentation include ion molecule reactions, charge changing collisions, and others, in addition to analytical applications.

In each embodiment only the rearmost set of wheels is powered. The track is a belt composed of a flexible material which in the first embodiment has a plurality of traction members secured thereto by bolts extending through the belt which are secured on the inner side by a strip opposite the traction members, such strip having a V-shaped portion which is received between the twin tires to retain the track in place. Each traction member includes a part flush to the belt through which the bolts are received, a further part extending from the first part outwardly and normally to the belt and a ground-engaging part extending from the second part in a direction parallel to the belt.

Abstract: An agricultural tractor with a hitching or lifting device which carries a farm implement. A control mechanism is provided on the tractor for adjusting automatically the height of the hitching device to enable the implement to follow irregularities in the underlying ground. The control mechanism includes a sensing member which, in one embodiment (FIG. 1), comprises two wheels which may pivot together about a common axis, such pivoting causing adjustment of the hitching device. In another embodiment, independently pivotable wheels or a further ground engaging member such as a skid may be located ahead of or behind the ground engaging wheels of a tractor which, by connection to the control mechanisms cause the hitching device to adjust to the height of the underlying ground.

Abstract: A soil working machine has at least one, preferably two rotors, one of which is at a higher working level than the other to achieve a relatively large working depth. The rotors are driven through a drive gear transmission located about midway along the length of the rotors. An adjustable coupling of the machine can be used to establish either one of two positions which are offset about an axis which extends transverse to the normal direction of travel. The transmission includes change speed gears in a first gear box for connection to a tractor p.t.o. and an output of the transmission is geared to a gear wheel housed in a flat gear box, the gear wheel being in driving engagement with pinions on the rotor shafts. The entire frame can be rotated to a limited extent relative to the transmission gear box owing to a flange connection between the two gear boxes and a setting device for their relative positions to one another.
