Title: Equipment for the selection of a lift cage for physically handicapped persons in the case of lifts with immediate alloation of target calls
Inventor: SCHRODER JORIS THEODOR
IPC: B66B1/20
Filed: 1991-01-18
Granted: 2002-06-18
Abstract: By this equipment, a cage suitable particularly for physically handicapped passengers can be selected in a lift group controlled by means of group control. For this purpose, call-registering equipments arranged on the storeys display a key, by means of which a switching circuit (20) can be activated. In this case, the switching circuit (20) is connected at the input side with a load store (13) and with a store (RAM1.2) storing the calls for the target storeys, wherein in the absence of an alighting call and for a load which is smaller than a certain load limit value, a first and a second condition for the selection of a cage are fulfilled. The switching circuit (20) is furthermore connected at the input side with the output of a comparator (17), which compares the travelling time of the cage to the call entry storey with the time needed by a physically handicapped person for the path between the actuated call-registering equipment and the shaft door of the lift concerned, wherein a third condition for the selection is fulfilled when the travelling time is greater. When all conditions are fulfilled, the cage selected in such a manner can participate in the call allocation procedure.
Patent CA-2036223-C (CA)
Inventor: CLEGG WILLIAM JOHN
IPC: C04B41/87

Granted: 2001-12-25
Abstract: Production of a layered ceramic product comprises positioning a first layer of a sinterable particulate ceramic material in face to face contact with a second layer of sinterable particulate ceramic material, sintering the particulate ceramic material and prior to effceting face to face contact, treating at least one of the surfaces to be positioned in face to face contact such that a zone of weakness is provided between the first and second layers of sinterable material.      The zone of weakness in the ceramic product acts to deflect a crack propagating across the layers of sintered material along the zone of weakness thereby increasing the work required to break the product. The layered ceramic product may also have an improved fracture toughness when a crack deflected along a zone of weakness does not propagate across an adjacent layer of sintered material from the tip of the crack in the zone of weakness.

Abstract: A commutator (10) for a motor is disclosed which includes a plurality of commutator segments (12) arranged in a cylindric array (14) such that the array has a cylindrical outer periphery (20) and two axial ends. An annular recess (26, 28) is formed adja-cent each end (22, 24) of the array so that a portion of each commutator segment (12) forms a part of the radially inner wall of each recess. Two or more rings (34, 36) constructed of an insulating material are provided and one or more rings are press fit into each recess so that the rings (34, 36) exert a radially inward force on the commutator segment (12). The anchoring portions of the commutator segments (12) are then encapsulated with a settable and electrically insulating material (40), such as phenolic. Upon hardening and curing, the phenolic secures the commutator segments (12) together. At the same time, the radially inward force exerted by the rings (34, 36) on the commutator segments (12) serves to stabilize the commutator segments (12) against movement relative to each other during high speed rotation of the commutator (10). A method for manufacturing the commutator is also dis-closed.

Abstract: In speech recognition and speech coding, the values of at least two features of an utterance are measured during a series of time intervals to produce a series of feature vector   signals.    A   plurality   of   single-dimension prototype vector signals having only one parameter value are  stored.   At  least  two  single-dimension  prototype vector signals having parameter values representing first feature values, and at least two other single-dimension prototype   vector   signals   have   parameter   values representing  second  feature  values.   A  plurality  of compound-dimension prototype vector signals have unique identification values and comprise one first-dimension and  one  second-dimension  prototype  vector  signal.  At least  two  compound-dimension prototype  vector  signals comprise  the  same  first-dimension  prototype  vector signal.  The feature values of each feature vector signal are   compared   to   the   parameter   values   of   the compound-dimension prototype  vector  signals  to  obtain prototype match scores.  The identification values of the compound-dimension prototype vector  signals having the best  prototype  match  scores  for  the  feature  vectors signals are output as a sequence of coded representations of  an  utterance  to  be  recognized.   A  match  score, comprising  an  estimate  of  the  closeness  of  a  match between  a  speech  unit  and  the  sequence  of  coded representations of the utterance, is generated for each of a plurality of speech units.   At least one speech subunit,  of  one  or  more  best  candidate  speech units having the best match scores, is displayed.
