Granted: 1994-05-03
Abstract: ABSTRACT OF THE DISCLOSURE     A method of applying top end stops on to a slide fastener chain comprises holding a top end stop or stops in between an anvil and a horn, moving the anvil and the horn together into alignment with a path of travel of the fastener chain, threading the fastener chain through the top end stop, clamping and attaching the top end stop by fusion to the fastener chain, and moving the anvil and the horn out of the path of the fastener chain.  This method is reduced to practice by an apparatus which essentially comprises an anvil and a horn which are vertically movable together in one instance toward and away from a horizontal path of the fastener chain and means of moving the anvil independently from and against the horn in another instance to clamp and attach the top end stop to the fastener chain.

Title: Facsimile compression for transmission
Inventor: ANDERTON DAVID O
IPC: H04N1/32
Filed: 1990-09-26
Granted: 1996-04-23
Abstract: A transmission arrangement is disclosed which facilitates compression of modem modulated facsimile signals for transmission on digital facilities. Thepresence of a facsimile call is detected and facsimile control messages are obtained by demodulating and interpreting the facsimile call control protocol. A controller is responsive to the obtained control messages for controlling a voiceband encoder to encode the control portion of the facsimile call and for controlling a so-calledfacsimile page demodulator to demodulate any facsimile page portions of the facsimile call to obtain a baseband digital bit stream. The encoded control portion of the facsimile call and the baseband digital bit stream representative of the demodulated, i.e., compressed, facsimile page portion of the facsimile call are transmitted along with control information (as side information) to a receiver. At the receiver, a replica of the original modem modulated facsimile signal is reconstructed in response to the control information and by decoding the control portion of the facsimile call and by remodulating the digital bit stream representative of the facsimile page portion of the facsimile call.

In the first position, the set is used as a desk unit with the side arms at the sides of the receiver portion receiving depression and the transverse member is at the end of the receiver portion receiving depression nearer the transmitter portion receiving depression.  In the second position the set is used as a wall unit with the side arms extending outwardly from the base.   The space between the side arms is adapted for receiving the receiver portion when in the desk position.  The side arms support the handset below the receiver portion when in the wall position.  The ends of the side arms remote from the transverse member each have an inturned flange portion to aid in retaining the handset in the wall unit position.

Abstract: Bispecific molecules which react both with the high-affinity Fc.gamma. receptor of human effector cells and with a target cell surface antigen are disclosed. Binding of the molecules to the Fc receptors found on effector cells is not blocked by human immunoglobulin G. The molecules are useful for targeting human effector cells (e. g. macrophages) against cells bearing the target antigen. For this purpose, bispecific molecules can be constructed containing the binding region derived from an anti-Fc.gamma. receptor antibody and the binding region derived from an antibody specific for the target antigen. Targeted effector cells can be used to destroy cells bearing the target cell surface antigen by cell-mediated antibody dependent cytolysis and by complement-fixation.

Abstract: The present invention relates to a soil compactor equipped with at least one movable drum. To generate the desired compacting forces, the drum is equipped with two oppositely rotating exciter shafts which are matched to one another in their phase positions so that, if the exciter shafts are vertically superposed, their centrifugal forces act horizontally and in the same direction, thus causing a moment free horizontal force to be exerted on the drum axis, while, with the exciter shafts disposed in a juxtaposed arrangement, the centrifugal forces are amplified in the vertical direction and compensate one another in the horizontal direction.

Title: Circuit breaker with protection against sputtering arc faults
Inventor: MACKENZIE RAYMOND WARREN
IPC: H02H1/00
Filed: 1992-09-25
Granted: 2002-10-22
Abstract: A circuit breaker includes an electronic trip device which responds to sputtering arc-type faults. Level detectors compare the current in the protected circuit to a plurality of threshold levels and timers time the intervals that the current remains above each threshold, with the threshold levels and intervals selected to generate a response envelope for a trip signal which approximates, with a selected margin, the response of the protected circuit to introduction of a selected inductive load such as the starting of a motor into the circuit. If the sensed current falls below a threshold level which was being timed, the associated timer is not cleared unless the current falls below the lowest threshold, so that if the sensed current increases above the associated thresholds timing resumes where it left off, and a trip signal wall be generated sooner than for an initial excursion above the threshold.      Both analog and digital timer implementations are presented.
