Abstract: Methods for spatially separating ac and dc electric fields in which materials are used having characteristics as dielectrics to the ac fields and as conductors to the dc fields. The apparatus for separating the fields utilizes homogeneous materials of moderate to high resistivity. The method is applied to the separation of fringe fields near the ends of quadrupole mass filters for the purpose of improving the efficiency of ejection and transmission of ions in mass filter devices.

Abstract: At a mitre joint between two adjacent portions of a channel-shaped sealing or trimming strip structure such as for trimming a flange around a door opening in an automobile, for example, the mutually contacting tapering ends of the two adjacent portions of the strip structure are reinforced by an L-shaped reinforcing member which bridges across the joint and is secured to these portions, or by separate straight reinforcing members fitted to each of these portions.

Abstract: A spreading implement has at least one hopper, preferably with two outlet spouts at the bottom thereof. Each spout has an outlet port through which material passes and a flow control device having holes is positioned beneath each port. A group of distributor pipes is mounted below a corresponding control device at each side of the hopper and the pipes extend laterally from the implement to terminate with outlets at different distances from the hopper. The inner ends of each group of pipes adjoin an inlet nozzle formed by open pipe channels and connectors that correspond to each pipe. The channels receive material from corresponding holes in the control device and the latter can be moved via a setting device to more or less register with apertures formed in a cover plate that overlies said channels. An enclosed air chamber is formed between the spouts at the bottom of the hopper and a blower forces air through the chamber into each inlet nozzle that enters the sides of the chamber.

Abstract: A spreading implement has a container with ports that lead into an air chamber pressured by a blower device. Delivery ducts communicate with the chamber and ports to receive material from an ejector disc rotatably mounted adjacent the ports. The ducts extend horizontally from the ports in a direction transverse to the direction of travel. The ducts have outlets that are spaced apart from one another and each outlet comprises a movable spreading member located adjacent the outlet end. The spreading members can be flexible hoses or pivotable discs that are rockable by a common driving mechanism or the members can be bladed or rotatable nozzles so that during operation material is spread over a wide area by each spreading member.

Abstract: A substructure and method of forming same for a building assembled from relatively large prefabricated box-shaped elements which are transported on highways to the building site. A concrete base slab is formed either by pouring or precast parts on an excavated building site. Large, heavy concrete substructure sections are transported by truck, tractor trailer or other transport to near the slab, but out of the excavation, where they are orientated with their longitudinal axes parallel to their desired position in the completed building. A plurality of truss-type beams are placed to form a bridge from the truck bed to the slab and pulleys are placed in anchors previously provided on the far end of the slab proximate its sides. Cables, connected on each side of the section remote from the slab, are led through the pulleys and back to a winch on the transport by means of which the section is caused to slide off the transport, across the bridge and the slab to the far end of the slab.

Abstract: A soil engaging roller has a central axis shaft and spaced apart plate-like supports secured to the shaft. The supports are upwardly extending with holes around their perimeters to receive elongated rod-type elements that form the periphery of the roller. The elements can have retaining devices in the form of transverse holes with pins that secure the elements in the holes of the supports. The rods are shiftable or reversible with respect to the supports so that as the contacting surfaces become worn the elements can be altered to occupy different longitudinal positions. The support holes can be punched out with bearing surfaces formed by the bent over rim. Also, the supports can be angled with respect to the shaft and the elements can have several transverse retaining holes to permit shifting and retaining of the elements to the supports.

Abstract: A cultivator or harrow has two groups of tined soil working members in a row that are driven to rotate about upwardly extending shafts. Each group is located on an opposite side of a frame portion center from the other. Between each soil working member, a driving shaft is positioned and pinion gears housed in the frame portion to turn all the shafts of one group in the same direction, but opposite to that of the driving shafts and the other group. The driving shafts can be fitted with additional soil working members and those soil working members on upwardly extending shafts can be replaced with smaller supports so that adjacent soil working members rotate in opposite directions. Alternatively, the smaller supports can be fitted with extension structures and two groups of soil working members are again formed. A dispensing mechanism can be mounted on the frame portion to deliver material between a rear supporting roller and the tines.

Hydraulic piston assemblies are mounted around the hub of the mechanism and connected to the inner pair of plates.

Abstract: A method of manufacturing prefabricated sections for buildings wherein metal frames have concrete cast between them which is heated and allowed to harden along a manufacturing line to form floor and wall components. Ceiling components with metal frames and, where applicable, roof components are also constructed in the manufacturing line. At the end of the manufacturing line, the floor, wall, ceiling and/or roof components are connected, form the desired section and moved onto an adjacent assembly line which is at right angles to the manufacturing line without altering the relative disposition of the sections whereby the longer sides of the section which were parallel to the length of the manufacturing line are carried transversely on the assembly line. The sections on the assembly line are connected together in the relationship they will bear in the finished building and doors, windows, panels and the like are added as the connected sections move along the assembly line from adjacent storage areas.

Abstract: A hay making machine has a rake that rotates on an upwardly extending axis and an outer circumference defined by a felly or rim to which elongated crop working elements are connected. The elements can be tines or flexible strips that are pivotally or flexibly associated with the felly or rim so that the elements respond to ground undulations or a control device and pivot or otherwise deflect. In one aspect, tines having supporting portions integral with outer bent end portions are spaced from adjacent tines a distance (between corresponding points) less than the combined length of the two aforementioned tine portions to ensure that crop is retained during rotation of the rake member. Alternate tines may have different lengths or the tines may have plates to facilitate crop retention. A wire or rope can be connected to the tines above their outer ends to enhance their crop working cooperation or the tines can be interconnected by tortional rod portions and/or loops that are integral for the same effect.

Abstract: A haymaking machine is provided with at least one rotary rake member having tines that are pivotable relative to a hub of that rake member about separate first and second axes to improve the tines ability to follow ground undulations during operation of the machine.
