Abstract: Bodies, or frames, of use in the formation of modular interconnect terminals, or terminal modules are shown. The bodies are formed, characteristically, from single pieces of material to include pockets or receptacles into which electrical contact elements may be fitted. Each body, or frame, includes regions about which it may be folded to provide a four-sided box-like structure. Before being folded the body is equipped with electrical contact elements which it supports in such a way that first terminals of the contact elements are accessible from outside the folded structure. A flexible printed circuit board having conductors arranged in patterns on at least one face is folded within the box-like structure and its conductors are connected to second terminals of the contact elements to provide selected interconnections between the electrical contact elements.
Abstract: An electrical filter connector includes a housing in which a dielectric insert member is positioned. A plurality of pin contacts extend through the dielectric member in parallel-spaced alignment for engaging complimentarily positioned contacts on mating connectors. Ferrite sleeves positioned over the pin contacts coact with individual metal layers deposited on the front and rear surfaces of the dielectric block and a central metal layer within the block to form individual pi filter networks for each pin contact. Electrical connections are maintained between the pin contacts and the individual metal layers by means of solder bridges which extend over the ends of the ferrite sleeves.
Abstract: An electrical contact adapted to be crimped onto an electrical conductor is disclosed. The contact comprises a body portion having an active contact element disposed at one end for connection to a complementary contact and a terminal element at the other end adapted to be fixedly connected to a conductor. The terminal contact element comprises a pair of spaced crimping arms disposed in a common plane and having opposite inside facing edges with beveled surfaces. The beveled surfaces provide a camming action during the crimping operation which permits the arms to pass one another and to completely encircle the conductor, while the arts remain in substantially the same plane, whereby the crimped arms provide a positive mechanical and electrical termination between the contact and the conductor.
Abstract: In a system for suspending an immersible package in water from a surface buoy with insulated electrical cable payed out from a coil in a pack attached to the descending package, a spring-biased braking arm on top of the pack is released to pivot against a center post (around which turns of coil are payed out) in response to a signal generated in the package at the required depth to brake descent of the package. Another signal generated in the package (after sufficient delay for the braking action to be completed) releases a spring-biased block against the cable in a guide just beyond the braking arm. The released block shoves the cable against conductive pins connected to a shunt lead from an electrical circuit in the package with sufficient force to cause the pins to penetrate the cable insulation.

Abstract: The present mechanism includes a vertically moving platform which raises and lowers a printing ribbon relative to the moving printhead of a printer. When the printhead is at its home position, the platform is at its raised position thereby locating the lowermost portion of the ribbon at the printhead. As the printhead starts to move during its printing cycle, the platform will progressively lower so that when the printhead is at the center of its travel, the platform will be in its lowered position, thus locating the uppermost portion of the ribbon at the printhead. As the printhead continues to the end of its travel, the platform will end up at its raised position thus locating the lowermost portion of the ribbon at the printhead. This raising and lowering of the platform presents the ribbon to the printhead in overlapping arched patterns, thereby utilizing the full width of a printing ribbon.

The pressure chamber includes a fluid passageway which connects both sides of the pressure transducer to the pressure being sensed and includes radially extending and axially extending portions in the sealing structure. The chamber is formed by a pair of plates, each of which includes a recess and one of the plates is mounted against shoulders on the other plate to minimize assembly pressure and warping of the pressure capsule.
Abstract: An apparatus matches control code signals and data signals between data processing units which employ different control code formats. The interface is especially suitable for use between a computer bus interface and a controller or between two separate controllers. It employs read-only memory circuits which convert control code signals from the computer bus into discrete controls and commands compatible with the code format of the controller. The read-only memory circuits are programmable to allow looping programs to be implemented.
Abstract: Connectors, for printed circuit boards and the like, are disclosed which may be cut to desired lengths. The connectors are formed from bodies of insulating material such as thermoplastic polyester, having receptacles, or cavities, which support pluralities of contacts. Each contact is positioned in one of the receptacles by engagement of a ridge in the body with a corresponding slot in the contact. The contacts are locked in their respective receptacles by a slide element which functions cooperatively with a slide receptacle in the contact block. An assembled connector may be shortened by severing the body to remove portions of the body bearing undesired contacts without disturbing the remaining contacts. Alternatively, before assembly, the insulating block may be cut to a selected length so that it will accommodate a particular number of contacts and avoid excess contacts.
