Abstract: A method of making a tubular member such as a bird feeder hopper having offset members extending integrally from the inside surface of the peripheral wall thereof into an internal cavity. A sheet-like member is initially formed with a plurality of wall sections interconnected by integral hinges and the offset members integrally formed on one surface thereof. The sheet-like element can then be folded or pivoted about the integral hinges to form the peripheral wall of the tubular member, with the offset members extending into the internal cavity defined thereby and the edge portions of the end sections secured as by heat sealing, complementary locking members, or a combination thereof.

Abstract: The use of a black housing in an electronic trap utilizing light to attract flies to an access opening in the housing with disposable glue or adhesive fly paper sheets overlying the light source in the housing has been shown to attract and capture many multiples of targeted insects, particularly in a fully lighted room, when compared to a fly trap with a white housing.

Abstract: An animal trap of the type having a base, back wall and side walls made of metal mesh and a roof or lid made of metal sheet. A vertically sliding door is provided at the front of the trap which is held in an upper open position by a trigger mechanism until the trigger mechanism is released by an animal stepping on a bait pan inside the trap. The trap is provided with door slides snap-fitted on the opposite side walls at the front of the trap which improves the rigidity of the trap and the effectiveness of door operation. The slides are extrusions in metal or plastic, each having a first channel which snaps onto the respective side wall and a second perpendicular channel forming a guideway receiving one edge of the door.

Abstract: Lockset has within its outer tubular spindle a radial dog which, depending on its position, couples or decouples the spindle and the outer handle. Dog is moved from one position to the other by pin on rotary motor shaft screwing in or out a spring encircling the shaft and attached to dog. Motor is in inner tubular spindle.

Abstract: This lock, which may be coded-keycard operated, has a set-table device on the inside of the door by which the maid, for instance, can be locked out. The lockout setting device is preferably in the form of a pushbutton or deadbolt turnpiece which manipulates a switch in the code-receiving circuitry. The lockout setting is automatically cancelled when the latch is retracted. When the setting device comprises a deadbolt turnpiece, the deadbolt is biased toward retracted position and the setting device holds the deadbolt extended. When the latch is retracted in the latter version, the retraction cancels the lockout setting and permits the deadbolt to retract under the power of the deadbolt biasing spring.The invention also includes a non-code-operated embodiment in which a deadbolt is spriing driven to retracted position as the latch is retracted in latching to protect the deadbolt, lock and door frame.

Abstract: A door closer is disclosed having an operating arm with a track traveler which mounts a plurality of rollers. The rollers engage between them the opposite sides of a track on the door. The opposite sides of the track each have outward concave faces. The rollers are ball-shaped, conforming to the faces of the track. A door holder is also disclosed which may be adjustably fixed at a position along the track, the traveler and the holder having the mating parts of a snap fastener which, when engaged, hold releasably the door at a fixed hold-open position.

Abstract: A door closer and holder comprises a cylinder shell having a piston sealingly reciprocable therein. A spring biases the piston toward one end of the shell, and the piston is connected through the ususal apparatus to the door. At the one end the operating rod of a shuttle valve extends into the shell and is engaged by the piston as it approaches the end. The shuttle valve selectively directs the return fluid flow through sweep- and latch-control valves. The assembly also includes a solenoid-operated "bullet" which closes off the return flow to hold the door open. The angle of the openness at which the door is held may be selected by setting a cam on the holder drive pinion which engages a switch to activate the solenoid.

Abstract: A tool for aiding in the fitting or refitting of elastic O-ring-type seals is provided. The tool includes a plurality of frustoconical sections, each section being especially adapted to be releasably retained on a member to which an O-ring is to be fitted. The sections also interfit so that they can be assembled in end-to-end relationship. Retaining structure for maintaining the sections in assembled form can also be included. Storage cavities may be formed in some of the sections for storing such items as O-rings. The tool is especially adapted for fitting O-rings to faucet valve stems of various sizes.
