US Patent:

45825009, Apr 15, 1986

Filed:

Feb 9, 1984

Appl. No.:

6/578052

Inventors:

Steven P. Hanson - Richfield MN
Wayne A. Kuna - River Forest IL

Assignee:

Marvin Glass & Associates - Chicago IL

International Classification:

A63H 1744

US Classification:

446423

Abstract:

A play service center for toy self-propelled reversible drive vehicles that includes a lift ramp powered by the vehicle. Rollers carried by the lift ramp transfer power from the driven vehicle wheels through a pinion gear that engages a stationary curved rack gear to raise and lower the lift and vehicle. At the top of the curved rack gear a number of teeth are omitted and a stop is provided to retain the lift in the raised position. In order to lower the lift, the vehicle drive is reversed. Levered pads provide additional traction for driving the vehicle off the rollers and lift ramp. A power take-off drives service equipment such as a power meter as well as a rotating buffer or drill. The meter includes a biased dial pointer that provides an indication of the power transmitted by the vehicle wheels through the driven rollers.

Appl. No.:

5/736265

Inventors:

Steven P. Hanson - Bloomington MN

International Classification:

A63H 3300

US Classification:

46 1C

Abstract:

An action toy having a platform with a resilient sheet member providing a playing surface of the upper side, the sheet member being supported so as to leave a space beneath it, and a manually operated, elongated leaf spring mounted so as to extend partially beyond the platform and partially within the platform underneath the sheet member in such a position as to intermittently engage the under side of the sheet member when the resilient strip is vibrated. The strip is mounted in the platform in such a manner that when the outer portion is vibrated by engaging and then suddenly releasing the outer end, the vibration is transmitted to the inner portion to cause the inner end to intermittently engage the under side of the sheet member. The playing pieces placed on the playing surface are designed for movement therealong when the playing surface is vibrated. For example, the playing pieces may have resilient feet inclined upwardly in the direction of the desired movement.

Abstract:

A polymer film is applied onto a surface of a laminated printed circuit board subassembly having vias. Holes are created in the polymer film to access the vias while the polymer film remains covering adjacent areas. The polymer film with holes allows placement of hole-fill paste in the vias while preventing unwanted hole-fill paste placement or migration to adjacent areas. After filling the vias with hole-fill paste, the hole-fill paste is preferably at least partially hardened or cured, and the polymer film is preferably removed, facilitating further assembly of a printed circuit board without unwanted hole-fill paste in other areas which could be difficult to remove, The invention includes improved processes for fabricating printed circuit boards, and is particularly useful for irregular circuit boards and rigid flex circuit boards. The invention also includes covered laminated printed circuit board subassemblies, covered with a removable polymer film.
