Abstract: ABSTRACT An edge connector for a printed circuit board or card is disclosed. In order to ensure that the card is aligned properly with connectors in the slot of the edge connector a novel biasing arrangement is provided.  This biasing arrangement comprises a passage located adjacent one end of the card-receiving slot and having a transverse wall sloping obliquely downwardly towards a near end wall of the connector and a wedge slidably positioned in the passage having a sloping surface conformably sliding along the sloping wall of the passage and a vertical surface opposite the sloping surface and facing into the slot for abutting engagement with a card as it is inserted into the slot.  A coil spring is arranged to bias the wedge upwardly in the passage.  In operation, the wedge is driven down the sloping passage by the card as it is inserted thereby increasing the slot length to accommodate the card width.  Concurrently, in cooperation with a ramp on the wedge and the coil spring, the card is urged against the far end of the slot.  The wedge positions itself so that the ver-tical surface thereon bears against a side of the card.

Abstract: ABSTRACT        An improved control for a resin bed water softener includes a microcomputer which is supplied with input data from a flowmeter indicative of the quantity of soft water leaving the softener.  In accordance with the flow data, the microcomputer determines the amount of water used since the last regeneration and also determines the average daily soft water consumption.  The microcomputer also coupled to a data input device and receives input data indicative of the total resin bed treating capacity and the incoming water hardness. At a prescribed hour each day, the microcomputer determines the remaining water softener resin bed treating capacity as calculated from the water hardness, the total resin bed treating capacity and the amount of water used since the last regeneration.  The remaining resin bed treating capacity is compared to the reserve established as a proportion of the average daily consumption of soft water and regeneration is initiated when the reserve is greater than the remaining resin bed treating capacity.

Abstract: STABILIZED FIBER OPTIC SENSOR            Abstract A fiber optic sensor comprises a length of optical fiber,  forming  a  loop,  and  a fiber  optic  directional coupler for optically closing the  loop.   The loop and coupler  form  a  resonant  cavity  for  light  circulating therethrough.  A PZT cylinder, about which the fiber loop is wrapped,  is utilized to control the total round trip phase delay of the circulating light, and thus, control the intensity of the optical output signal W0.  The phase delay is adjusted to a point Z where the optical output signal W0 is at maximum sensitivity to changes in phase. When the fiber loop is exposed to, e.g., acoustic waves, the loop length changes correspondingly, thereby causing the phase delay, and thus, the optical output signal W0 to vary.  By detecting variations in output signal intensity, the frequency and intensity of the acoustic waves may be determined.   The sensor also includes a feedback system for  stabilizing  the  fiber  loop  against  low frequency thermal drift.

Abstract: ABSTRACT          An improved cellular flooring service distribution system is disclosed comprising a cellular flooring unit in which a dividing means provides a plurality of open parallel conduits in a single valley of a corrugated sheet, an overlying trench providing a plurality of transversely oriented parallel passageways which have access to said conduits and an isolating means to selectively isolate at least one conduit and passageway from the remaining conduits and passageways.  Cover means and access housings are also provided.  Since the above components do not require any special fabrication, they can be efficiently and cheaply mass produced, preferably from sheet metal.  Service lines may be placed in open conduits and passageways prior to covering to eliminate the need for feeding the lines through enclosed cells.  Since no base plate is required on the corrugated sheets, less material it used than with conventional units, the sheets can be compactly nested to facilitate shipping and handling and fire resistance is increased.  Fire resistance is further increased by allowing concrete to flow beneath the trench into the undivided valleys of the sheet.  Various embodiments of the general concept are disclosed.

Abstract: GAS SEAL FOR SEMICONDUCTOR PROCESSING EQUIPMENT          Abstract of the Disclosure During production of laser diodes, crystals on which the laser diodes are formed are subjected to two high temperature processes:  diffusion and alloying.  These steps are performed in a quartz process tube in an oxygen free atmosphere.  At some stage in the process the crystal must be moved from a cool zone to a hot zone within the tube and this is done by means of a push rod which extends through an aperture in the diffusion tube.  The conventional arrangement for sealing around the push rod acts to clamp the push rod in position.  Thus, temporarily, while the push rod is being moved the seal must be partly released and its sealing action is inferior.  To maintain the process atmosphere free of reactive gas there is proposed by the invention a mechanism for flooding the sealing area between the push rod and the process tube with an inert gas while the sealing means is temporarily released.      -?-

Abstract: TACTILE SENSOR ARRAY:  ROBOTIC SYSTEM AND MANUFACTURING METHOD UTILIZING SAME            Abstract A movable part of a robot, such as the fingers of the robot hand, are provided with an array of tactile elements mounted on a substrate.  Each element includes a magnetic dipole embedded in a compliant medium on one side of the substrate and a magnetic sensor on the other side of the substrate.  The dipole and sensor are in parallel planes.  A force or torque deforms the compliant medium and displaces the magnetic dipoles with respect to the sensor. The sensor detects the change in magnetic field and produces an electrical signal which is used to control the robot.  Magnetoresistive sensors are preferred.  To detect torque, each element illustratively includes four sensors arranged at 90° to one another and a magnetic dipole oriented at 45° to each sensor.  Also described is the handling of objects by a robot having such a tactile array in its gripper or hand, and the use of a robot to bring an object into contact with such a tactile array mounted, for example, on a table top, thereby enabling pattern recognition functions.

Abstract: ABSTRACT OF THE DISCLOSURE An    electroencephalograph   (EEG) signal analyzer allows the examination of the changes in EEG cerebral activity at various sites in response to an event  (e.g.  a  stimulus  or  task).   The  analyzer includes one or more signal processing modules which periodically sample the EEG signal from each of the sites, convert the sampled signals to digital sample values, and store those values.  Digitized waveforms based on the stored digital sample values and having a length equal to or greater than the period of the lowest frequency of interest are transformed from the time  to  the  frequency  domain.   For  each  of  a plurality of epochs, a frequency spectrum is produced having frequency content which has a content uniquely due to the digital sample values from that epoch.  A weighted mean frequency value for  each  site during each   epoch   is   derived   from  the   corresponding frequency spectrum.   Based  upon  the  weighted  mean frequency values,  output signals are provided to a display   and   a   printer   to   produce   graphical representations of cerebral activity with time at the various sites in response to the event.
