Abstract: Retrofit apparatus for being mounted on a telephone terminal block previously mounted at a subscriber's premises and for providing a demarcation point at the telephone terminal block between an incoming telephone line and a subscriber premises line previously connected through first terminal means provided on the telephone terminal block, including telephone jack means for being connected to the first terminal means; second terminal means for being connected to the subscriber premises line upon the subscriber premises line being disconnected from the incoming telephone line; and telephone plug means connected to the second terminal means and for being plugged into the telephone jack means to interconnect the incoming telephone line and the subscriber premises line and for being unplugged from the telephone jack means to provide the demarcation point and permit the plug of an operating telephone to be plugged into the telephone jack means to facilitate determination of whether a fault exists on the incoming te

Abstract: A network interface device and enclosure adapted to interconnect incoming telephone wiring to subscriber premises wiring. The device, according to one embodiment, comprises first electrical terminals adapted to be connected to the subscriber premises wiring, second electrical terminals adapted to be connected to the incoming telephone wiring, a removable module disposed between the first and second electrical terminals, the module having space for a telephone circuit and the module having electrical connections for connecting the module with the second terminal; a cable coupled to the first terminals, the cable including a plug at an end of the cable distant from the first terminals, and a jack located on the module adapted to receive the plug, the jack being electrically coupled to the electrical connections for connecting the module with the second terminal.

Abstract: A telephone network interface enclosure adapted to interconnect incoming telephone wiring to subscriber premises wiring.

Abstract: A multiline telephone test receptacle for allowing testing of more than one telephone line connected to the receptacle in a convenient manner, for example, with a single line telephone set, without requiring special connections. In one embodiment, a movable member having an opening which is positionable in two positions over a telephone jack cavity allows contacts of a telephone plug to engage different ones of the telephone lines connected to the jack in the two positions, thus providing a convenient means for testing the two lines. In another embodiment, the contacts of the telephone jack cavity are disposed on a movable member and the opening is fixed. The telephone test receptacle can be expanded to allow testing of more than two lines.

Abstract: A manually operable input control member is mounted in a sewing machine for linear movement into a reverse feed controlling position and for pivotal movement therefrom into a reverse feed sustaining position wherein the member is held against a spring which is provided to bias it toward an unactuated hands off position in the machine.

Abstract: A clutch element fastened to the end of a sewing machine main shaft by a shouldered screw is slidable thereon to a first position wherein axially extending clutch fingers thereof extend through guide notches in an interlock element fixed to the main shaft by the shouldered screw, into axially aligned recesses in a belt driven handwheel so as to drive the sewing machine main shaft. In a second position of the clutch element, the axially extending fingers thereof are withdrawn from the recesses in the handwheel so that the sewing machine main shaft is not driven. Detent means are provided to maintain the clutch element in a selected position.

Abstract: A control mechanism is attached to a sewing machine frame with a bayonet type connection including a slotted plate on the control mechanism and a spring biased pin which is axially movable in the frame and is extendable through an enlarged one end portion of a slot in the plate. The pin includes an enlargement which, when the plate is turned is caused to enter an opposite end portion of the slot and lock the control onto the frame.

Abstract: A sewing machine is provided with stitch length control mechanism including a gear rack which is slidably mounted in the base of the machine so that it can be linearly translated to selected positions by an operator, and including a helical gear sector which is operably associated with a feed regulator shaft and meshes with the gear rack at a low helix angle effective to prevent other than operator induced movements of the gear rack.

Abstract: An automatic control means for overriding the manually operable fast/slow control switch of a sewing machine to assure slow speed operation while the machine is operating in skip stitch mode, such as while basting to facilitate positive latching and unlatching of the needle bar. The automatic control means cooperates with the needle bar lateral jogging mechanism of the sewing machine such that when the needle bar is jogged beyond a predetermined range of laterally jogged positions, wherein skip stitch mode is effected, the automatic control means will automatically impose slow speed operation independent of the setting of the fast/slow control switch as selected by the operator.

Abstract: A camera construction is provided which is adapted to removably accommodate a cartridge of self-developing film. The cartridge presently available on the market includes a rectangularly shaped container having a self-contained battery and a stack of photographic sheets of like configuration disposed therein and arranged so that only the uppermost sheet may be exposed. Subsequent to exposure, the uppermost sheet is slidably removed from the container and discharged from the camera housing through a suitable opening formed therein. The invention in question relates primarily to the mechanism for automatically removing the uppermost sheet from the cartridge container and then to discharge same from the camera housing whereupon the self-developing process for the discharged sheet will occur within a predetermined time.

Abstract: An apparatus for mechanically moving a sliding contact associated with an indexing assembly along a series of contact pads. The contact pads are sequentially arranged whereby flash lamps connected thereto and disposed in an array mounted on an associated camera are fired in sequence upon closing of an energizing circuit in the course of actuating the camera shutter. The apparatus includes an indicator device for indicating which flashlamp in the array is electrically connected to the firing circuit through the sliding contact.
