Title: Apparatus for forming wall reinforcements in multiple individual cartons
Inventor: NOWACKI ULRICH G

Granted: 1982-11-09
Abstract: Abstract of the Disclosure Disclosed is an apparatus for forming wall rein-forcements in multiple individual cartons.  The apparatus includes a single entrance for admitting semi-finished cartons having vertically extending end wall flaps.  The cartons are serially admitted centrally of the apparatus to a transport platform and distributed alternately to multiple wall reinforcements formers.  The wall reinforcement formers are located in association with opposite ends of the plat-form and include work stations located along the platform.          At the work stations, the vertically extending carton flaps are bent out of the vertical by flap preformers, as glue is applied in an automatically determined pattern to the wall to be reinforced.  The glue pattern is determined by: the spacing of multiple interruptable light beams arranged transversely of the carton's paths, the glue applicator and the carton itself.  Subsequently, flap folders, employing rigidly mounted rollers, drive the preformed flaps into the carton.  Within the cartons, the wall reinforcements are formed as the rollers compress the flaps and glue patterned walls against anvils located in bracing relationship at the carton's exterior.  Thereafter, reinforced cartons are ejected from the apparatus at multiple exits.

Abstract: ABSTRACT OF THE DISCLOSURE                       TIME  SWITCHES     A time switch (100) comprises terminals (1103 spaced around a slip ring (108) connected to a voltage source (V).  A motor (104) drives a brush (102) to sequentially connect the terminals (110) to the slip ring (108) to energise the terminals in sequence. Each terminal (110) - as shown for one of them designated 112 - is connected via a respective transistor (116) and manually operable switch (124) to a pair of common output conductors or bus-bars (130, 132), whereby for each successive period of time corresponding to each successive terminal (110) being energised the conductors (130, 132) are energised in accordance with the setting of a respective one of the switches.  Thus, a desired time-varying pattern of energisation of the conductors (130, 132) to accomplish a control function, e.g. the control of a central heating system to provide different heat outputs at different times of the day, can be set up at will simply by adjusting the various switches (124).               .

Abstract: ABSTRACT OF THE DISCLOSURE   An improved lock thread convolution has a resiliently deflectable spring rib or projection which presses a load bearing or pressure flank of the lock thread convolution against the flank of a mating thread.  The pressure between the two flanks retards rotation between the lock thread convolution and the mating thread.  In addition, the flank pressure retards axial movement between the threads upon application of vibrating or oscillating loads to the threads.  The resiliently deflectable spring rib or projection has a base which is integrally formed with the crest of the lock thread convolution and an arcuately curving body which extends away from the crest along the non-pressure or unloaded flank of the lock thread convolution.  The spring projection is deflected by engagement of a side surface area of the projection with the flank of the mating thread to provide a resilient spring force urging the pressure or load flank on the opposite side of the lock thread convolution into abutting engagement with a flank surface of the mating thread convolution.

Abstract: ABSTRACT OF THE DISCLOSURE      Hydraulic "squeeze cylinders" control the size of the discharge orifice on an extrusion baler and are operated by a control circuit that relieves pressure in the cylinders in response to the build-up of a certain predetermined pressure level in the circuit.  Pressurized fluid for the squeeze cylinders is supplied by a single-acting pump cylinder that is connected between the plunger head and its pitman rod in such a way as to deliver a charge of pressurized fluid into the circuit on each compression stroke of the plunger.  A pilot-operated relief valve is operated by circuit pressure when the latter reaches a predetermined pressure level to block flow from the pump cylinder and open a relief path for fluid in the squeeze cylinders.

Abstract: This invention is a toy in which two principal assemblies of parts are made to counter-rotate by a central internal coil spring, previously wound up by hand, whose tension is released when the weight of the toy, when it is placed on a flat surface, disengages a one-way clutch. It is equipped with a means of freeing the inner end of the spring from its arbor when the energy of the spring is spent, so that the parts may continue to counter-rotate by inertia without damage to the spring. It is equipped with a lighting system using flashlight bulbs and batteries to show flashing light through window apertures and circular holes in the rim of the upper part. The batteries are contained in a central tubular shaft, and the flashing effect is produced by a bimetal thermal relay in the circuit, controlled by a switch on the upper part. When in operation the toy rests on a tricycle gear of three hollow spheres on axles radially disposed in the base to allow free rotation of the base. All parts except light bulbs, batteries, wiring, contact parts, switch and relay, and parts necessarily made of metal such as springs, axles, a ring carrying a hook to engage the inner end of the main spring, and bolts for assembly, may be made of impact-resistant synthetic plastic insulating material by injection molding or other appropriate process. External parts are covered with paint to resemble gleaming metal, and window apertures and illumination holes are covered with thin tinted transparent plastic film.
