Abstract: A multi-step control apparatus is provided for raising and lowering a patient treatment table in response to predetermined successive motions of the foot of an operator. An operating rod mounted transversely of the table has a foot pedal on each end thereof and is biased to a mid position both longitudinally and rotationally. In response to inward pressure on either foot pedal a timing cycle is initiated during which the doctor may then initiate a raising or lowering cycle for the table by stepping on one side or the other of the foot pedal and rotating the operating rod out of a neutral rotational position. However, a raising or lowering cycle cannot be initiated without first moving the operating rod inwardly to initiate the timing cycle so that accidental or inadvertent raising or lowering of the table by simply rotating the foot pedal is prevented.

Abstract: A microcoil having a winding on a composite core made up of a portion of substantially magnetic material and a portion of substantially non-magnetic material. The winding is split so that a part of the magnetic material core portion is exposed, and a laser is used to remove material from the exposed part of the magnetic core portion. The inductance of the coil is measured during the removal of the magnetic material, and the inductance of the coil is trimmed to a desired value through the removal of an appropriate amount of magnetic material. The non-magnetic core portion serves as a support structure for the portions of the winding on the core even if a substantial portion of the magnetic material is removed.

Abstract: A coil assembly having a core and a winding on the core, wherein a contact element electrically connected to the winding is both mechanically clamped and bonded to the core. In an exemplary microcoil assembly having a C-core, a generally U-shaped contact element is bonded to each foot of the core by epoxy and mechanically clamped to the core foot to hold the contact element in position while the epoxy cures. One end of the coil winding is soldered to one of the contact elements and the other end of the winding is soldered to the other contact element. The coil assembly is subsequently soldered onto a printed circuit board. Each contact element may include a pin portion to be inserted into a printed circuit board.

Abstract: A knock-down tray rack having a horizontal base member, a pair of bow-shaped support members, and a pair of unitary side panels incorporating upright sleeve members at opposite side edges thereof for receiving the upright leg members of the support members, and being provided with opposed vertically spaced ledges for supporting trays thereon. The leg members of the support members are adapted to be easily telescopingly fitted in the corresponding sleeve members of the side panels so that the bow-shaped support members span the side panels and so that the bottoms of the leg members are securely received within corresponding socket members in the base member. The base member may be further supported by casters having mounting extensions extending into the open bottom ends of the depending leg members of the bow-shaped support members.

Abstract: A chiropractic table cushion drop release mechanism wherein a latch member which is spring biased into engagement with a detent mechanism to hold the cushion in an elevated position is restrained from inward movement after it has released the detent so that the frictional drag of the spring biased latch is removed and the cushion can drop freely to a desired lower position.

Abstract: A patient treatment table includes a table frame, a hip board fixedly secured to said frame and a head board fixedly secured to said frame and spaced from said hip board. A transparent flexible arch member, of such thickness that it can maintain an adjustable height position under the patient's weight without requiring edge reinforcement, is pivotally mounted to said frame adjacent to and below the top surface of said head board and a slide member extending across the table beneath the edge of said hip board provides a pivotal support for the other end of said arch member. Said slide member may be adjusted relative to said hip board by means of an enclosed, motor driven lead screw actuator to bow said arch member upwardly from a minimum height position in which the top surface of the arch member is substantially the same as the upper surfaces of said head and hip boards.

Abstract: An improved tree stand for supporting and stabilizing a tree therewithin without the requirement of a trunk-encircling ring. The stand comprises a bowl and a plurality of legs, each leg carrying a trunk clamping screw at an inner end and received through one of a plurality of apertures provided in the bowl rim. Radially extending struts pivotally connected to the legs are urged into compressive engagement with a sidewall portion of the bowl by the engagement of the clamping screws with the trunk.

Abstract: A one-half turn inductor is formed in a mold having a series of spaced ribs forming grooves therebetween, a U-shaped coil has its bight portion positioned in a selected one of the grooves corresponding to the inductance value of the inductor with the legs of the coil projecting beyond the cavity. Plastic is introduced into the cavity to create a coil form with the coil embedded in the plastic. The ribs and grooves form an inspection window consisting of spaced parallel rungs, one of said rungs being an exposed segment of the coil, the remainder being plastic.

Abstract: A patient treatment table is provided wherein a patient table which is pivotally mounted on an upper frame may be tilted from a position near the vertical to a horizontal position in engagement with the upper frame and the upper frame and patient table are elevated to a desired adjustable height relative to a fixed lower base member in one smooth continuous motion. Conversely, when a patient is to be removed from the table the upper frame and table are lowered to a minimum height position and the table is tilted to a near vertical position again in one smooth continuous movement.

Abstract: Disclosed is an air make-up unit mounted within the confines of a conventional outside wall of a frame building between the 16" on-center studs. The unit includes a rotary blower with a horizontal tangential discharge, the latter having heating elements therein and being encased in a vertical wall of insulation which extends within an insulated air chamber defined by a telescoping outer casing. Positive air pressure is maintained within the building by air-pressure-sensitive controls located within the building and controlling the two-speed motor. The latter is thermostatically controlled to be operated at a slower speed when colder weather prevails. It is also controlled and energized by a humidistat located within the building to force outside air into the building and diminish the humidity therein when needed.

Abstract: A method for producing embossed designs on work surfaces such as on molds, rolls or dies. A photomechanically imageable transfer material is exposed to the design to be embossed. The material is developed and the acid resistant design material remaining on a backing sheet is mechanically transferred to the work surface by burnishing the back of the backing sheet. The surface is then etched and the acid resistant design elements removed so that the embossed work surface is ready for use.

Abstract: Large-format embossing tools for applying a given contour to synthetic-resin plates, sheets or foils, e.g. to produce a leather-like or wood-like pattern therein, are produced by printing onto the plates the predetermined pattern in an etch-resist and then repeating the process with a different pattern so that portions of the tool, e.g. an embossing plate for multideck presses, are etched more and less deeply.

Abstract: A reed relay wherein the coil and switch terminals are disposed generally in planes parallel to the axis of the relay. A bobbin is molded onto a switch consisting of glass-enclosed contacts with leads projecting therefrom. Coil terminals are molded integrally with the flanges of the bobbin. The coil leads are connected to one side of the terminals which are then bent into notches in the flanges. The switch terminals are formed alternatively by bending them into notches in the bobbin flanges to project at right angles to the axis of the bobbin or by laying a separate terminal in the bobbin and welding the terminals to it. A housing is molded around the bobbin and the respective coil and switch terminals are bent into an in-line position.
