Patent ES-450896-A1 (ES)
Title: Method and apparatus for building a closed torus tire
IPC: B29C67/00
Filed: 1976-08-21
Abstract: A method and apparatus for building a closed torus pneumatic tire in which the components of the tire, exclusive of the belt and tread structures, are wrapped about a cylindrical former, inextensible bead rings are positioned about the former in positions spaced axially apart substantially the same as the final desired axial spacing. The former is radially expanded and expands the carcass structure to clampingly engage the bead rings. Each axially outer end portion of the carcass structures is folded over toward the axial centerplane of the drum in a manner in which the carcass is free of internal restraint at the fold. Each axially outer end of the folded over end portion of the carcass structure freely contracts radially into position to be clamped by a pull-over ring and is pulled axially across the former to a predetermined position past the midcircumferential centerplane of the former and released. A sidewall restraint ring moves into position adjacent the fold to prevent roll back of each end portion. The overlapped center portions of the ply structures are stitched together to form a closed envelope construction. A preformed belt and tread structure is disposed circumferentially about the former with the centerplanes of the belt, tread, and carcass coincident. The envelope is inflated into engagement with the preformed belt and tread structure which are in turn stitched to the carcass.

Title: Two mass vibratory material handling apparatus and methods of manufacturing and fine tuning the same
IPC: B65G27/20
Filed: 1976-09-03
Abstract: A two mass vibratory material handling apparatus has a first mass that includes a vibration exciter of the rotary eccentric weight type and a second mass that includes an object to be vibrated. The two masses are interconnected by resilient elements designed to permit a desired vibration amplification from the vibration exciter to the object to be vibrated. The vibration exciter has a drive with an adjustable drive ratio located between a fixed r.p.m. at full voltage motor drive shaft and a shaft that rotatably supports eccentric weights. Variable pitch pulleys or a set of pulleys having various pitch diameters and provided so that pitch diameters can be selected therefrom for mounting one pulley on each shaft with a drive belt trained about the pulleys and thus, provide a drive ratio enabling the fixed frequency motor to drive the eccentric weights at a selected operating frequency. The resilient elements can be designed to amplify vibration along a predetermined line of attack or to flex in that direction while amplifying vibration perpendicularly thereto or to provide a combination of such vibration amplifications to impart an elliptical motion to the second mass. The apparatus can be manufactured without undue care in maintaining a designed spring rate for the resilient elements or maintaining the designed weight of the two masses since after manufacture and assembly, the apparatus can be fine tuned by weighing the two masses, measuring the amplitude of vibration of the mass including the object to be vibrated at a known frequency, selecting an operating frequency for obtaining a desired vibration stroke, and adjusting the drive ratio to operate at that frequency.

Title: Xerographic copier system including a hot roll fuser.
IPC: G05D23/00
Filed: 1978-10-02
Abstract: The rolls (31, 32) of a hot roll fuser are normally closed at a predetermined time prior to the arrival of a copy sheet at the roll nip. If, however, the temperature of the backup roll (32) exceeds a predetermined value, the rolls are closed at a shorter time before the copy sheet arrival. A sensor (50) is coupled to threshold circuit (53) which applies enabling inputs to AND gates (64, 66). These gates receive timing signals from a counter and decoder system (71, 73, 74, 75) and, in accordance with the output from the threshold circuit (53) apply either an early or a late pulse to a fuser roll closure latch (78). Instead of directly measuring the backup roll temperature, the timing of opening and closing of the fuser rolls may be monitored to predict the temperature of the backup roll.

Title: An electrical fuse holder.
IPC: H01H85/20
Filed: 1980-02-05
Abstract: A fuse holder for a miniature cartridge fuselink, comprises a hollow body and a fuse carrier, formed as plastic mouldings, and two spring metal contact members engagable witih the outside of the body and having central parts which project into the cylindrical chamber of the body through slots in the body wall. The construction is such that the fuse carrier can only be inserted into the body when it is oriented in one predetermined position relative to the body and, in this position, there are barriers of insulation material between the end caps of a fuselink snapped into the fuse carrier and the potentially live electrical terminals on the body. When the fuse carrier is fully inserted into the body, it can be rotated through one half turn to engage the end caps of the fuselink with the contacts. The fuse holder prohibits a user from touching any live terminals, and the end caps of the fuselink cannot engage the contacts of the holder while the fuse carrier is being inserted into or removed from the holder.
Patent ES-488348-A1 (ES)
Title: Thermostat.
IPC: H01H37/00
Filed: 1980-01-28
Abstract: A thermostatic switch (10) employs a switch blade (22) having spaced thereon a set of service contacts (16, 20). One end of the blade is supported by a heat collapsible support (46) and a second set of contacts (26, 24), the contact sets being electrically in series. The service contacts are actuated by a slider (30) driven by a bi-metallic heat sensing element (32). A spring loaded button (52) biases the blade (22) against the collapsible support. Both sets of contacts (16, 20), (26, 24) are normally closed and upon the thermostat experiencing excessive temperatures the heat-collapsible support yields to the force of the bias spring (54) and causes the second set of contacts (26, 24) to open irrespective of the condition of the service contacts (16, 20).
