Title: Wear-resistant coating of cutting tool and method of applying same
Inventor: GAVRILOV ALEXEI G
IPC: C23C10/06
Filed: 1986-05-27
Granted: 1990-11-27
Abstract: WEAR-RESISTANT COATING OF CUTTING TOOL       AND METHOD OF APPLYING SAME                         ABSTRACT A wear-resistant coating of a cutting tool has at least a single layer of an interstitial phase which  comprises  alloying  components  and  a  non-metallic one the content whereof falls  within  the boundaries of a region wherein a compound of this interstitial phase having an all-best thermodynamic stability is homogenous.    One of the alloying com-ponents functions as a catalyst which facilitates the compound with an all-best thermodynamic stability to form.     A method  of  applying  the  wear-resistant coating to a cutting tool provides  for condensing matter by virtue of ion bombardment and consists in introducing the catalyst into a vacuum by evaporating the material of a cathode and depositing a layer of coating on the base material of the cutting tool at a temperature thereof which permits a catalytic reac-tion to take place owing whereto the content of the non-metallic component falls within the boundaries of a  region  wherein  the  compound  with  an  all-best thermodynamic stability is homogenous.

Title: Scoring arrangement for a tamper-indicating plastic closure
Inventor: SCHETZSLE JOHN
IPC: B26F1/18
Filed: 1987-01-30
Granted: 1991-08-06
Abstract: ABSTRACT OF THE DISCLOSURE        A tamper-indicating plastic closure construction is disclosed which includes an annular pilfer band (22) which depends from an annular skirt portion (16) of the closure.  The pilfer band is partially detachably connected to the skirt portion by frangible ribs (32), and remains connected to the skirt portion attendant to removal of the closure from a container.  To facilitate such removal, the pilfer band includes a fracturable portion (33) defined by a pair of vertically spaced, vertical scores (36).  In order to substantially prevent any propagation of the upper one of the vertical scores (36), another score (39) is formed in intersecting relation thereto.  Consistent manufacture and reliable performance are further promoted by the formation of a stabilizing score (40) in operative association with the fracturable portion (38) of the pilfer band.

Title: Driver for framer's and glazier's points
Inventor: KOZYRSKI VINCENT T
IPC: B25C1/02
Filed: 1987-03-18
Granted: 1991-07-30
Abstract: ABSTRACT OF THE DISCLOSURE    A machine for driving glazier's and framer's points utilizes a push plate which is effective to drive the points at both of two levels.

Title: Method and apparatus for providing variable reliability in a telecommunication switching system
Inventor: BERANEK ALLEN JAMES
IPC: H04Q3/545
Filed: 1987-04-14
Granted: 1990-05-01
Abstract: Abstract: In a telecommunication switching system adapted for handling call signaling information and data in packet format, a number of protocol handlers are interconnected by means of a local area network. A variable number of spares may be available for each group of protocol handlers as defined by a ratio table stored in the memory of the systems control processor. The ratio table may be changed from time to time to redefine the ratio of spares to actives for each group. In response to a request to activate an additional protocol handler in a group, the ratio table is consulted and an error message is generated if the activation of an additional protocol handler causes the specified ratio to be exceeded. A logical address is recorded in the memory of the system's control processor for each active protocol handler and in the event of reassignment of protocol handlers, a spare protocol handler is selected and the logical address associated with the priorly active protocol handler is assigned to the selected protocol handler. In addition, the local area network address of the priorly active protocol handler is assigned to the selected spare protocol handler. A data distribution circuit operating under the control of control data selectively distributes data packets from connected communication lines to the active protocol handlers.

Title: Differential binding of potential sensitive materials by lymphocytes
Inventor: CERCEK BORIS
IPC: G01N15/14
Filed: 1987-11-23
Granted: 1993-01-12
Abstract: Abstract The method of  the present invention comprises contacting a suspension of viable lymphocytes with a solution containing a membrane potential sensitive fluorescent dye, The contact between the lymphocyte suspension and the MPS dye is maintained for sufficient time to permit labelling of the lymphocytes by the MPS dye material. The labelled lymphocytes are passed individually through a focused source of excitation energy causing any MPS dye material to fluoresce.  The fluorescent emission from each cell is recorded as a pulse and the number of pulses of each intensity are recorded,   The distribution of the number of pulses versus the intensity is prepared distribution is bi-modal. A first peak includes pulses of low flourescence intensity and a second peak comprises pulses of high fluorescence intensity.  A ratio of the total counts of low fluorescence intensity to the total counts of high fluorescence intensity  produces a  factor which distinguishes lymphocytes derived from bodies afflicted with malignancy from bodies which are not afflicted with malignancy.
