Title: Method and apparatus for converting a multi-roll container stream into a single roll stream
Inventor: MEINDL THEODOR
IPC: B65G47/68
Filed: 1990-08-23
Abstract: Abstract of the Disclosure Method  and  installation for  converting multi-track flow of containers into a single track flow, wherein an infeed conveyor is slanted relative to the horizontal plane, an intermediate conveyor is slanted at the same angle and so is a discharge conveyor.  The intermediate conveyor is at least as wide as the infeed conveyor and abuts onto it.  The discharge conveyor is arranged parallel and lateral to the intermediate conveyor.   There is a cross-over plate between the infeed and intermediate conveyors. The advanced containers are first pushed onto the cross-over plate by the containers coming in on the infeed conveyor and they remain abreast of each other as they are then pushed onto the intermediate convey-or, whereby they are gradually accelerated to a speed which is lower than the speed of the discharge convey-or.   The cross-over between the individual belts of the intermediate conveyor, which respectively run at speeds which increase down the slant onto the dis-charge  conveyor,  results  from  the  downward  force generated by the slant.
Patent CA-2024527-A1 (CA)
IPC: G01S5/30
Filed: 1990-09-04
Abstract: An acoustic position sensing apparatus is described which determines the position of an indicator in relation to a datum surface  or volume.   The apparatus  comprises  an acoustic point source transmission device mounted on the indicator  for  transmitting  a  sequence  of  periodic acoustic oscillations, and a plurality of acoustic point receivers  positioned  about  the  datum  surface  for receiving  the  acoustic  oscillations.   Comparators  are connected to each acoustic receiver for converting the received acoustic oscillations  to square waves having logical up and down levels.  A register or other time determining circuit is coupled to each comparator and receives at least a leading portion of a square wave and provides an output if  it determines that the portion exhibits  one  of  the  aforesaid  logical  levels  for  a predetermined time duration.  A processor is responsive to the outputs from the registers to find the position of the indicator.            The  acoustic  point  source  transmission  device  is configured both  as  a  linear  stylus  and  as  a  planar "puck",  both  having  at  least  a  pair  of  acoustic transmitters.  The apparatus employs, for two dimensional position detection,  at least three acoustic receivers arranged in a non-linear fashion.  A three dimensional position detector system is described which employs four receivers, three of which are oriented in one plane and a fourth in another plane.

Title: Active armour protection system for armoured vehicles
Inventor: LLOYD PETER G
IPC: F41H11/02
Filed: 1990-10-05
Abstract: A sensor system for defending armoured vehicles against projectiles through the use of active armour.      A thermal sensor detects a projectile's presence, and a laser proximity sensor determines its location. A doppler sensor distinguishes between threatening and nonthreatening projectiles by measuring the projectile's velocity. The sensors are positioned in a housing with a segmented spherical window, wherein each sensor can detect the projectile through a window segment having a filtering characteristic which is matched to its associated sensor. An eyelid shutter, which can open and close, protects the window from small arms fire and shrapnel. A conical deflector protects the sensor system from objects such as tree branches. Heater elements are used to clear ice and snow from the window, and the eyelid shutter removes other material through the use of a cleaning liquid delivery system and rubber wipers.

Title: Platelet-derived growth factor b chain analogs and method for homogeneous production thereof
Inventor: THOMASON ARLEN R
IPC: A61K38/22
Filed: 1990-12-19
Abstract: Abstract NOVEL PLATELET-DERIVED GROWTH FACTOR B CHAIN ANALOGS AND METHOD FOR HOMOGENEOUS PRODUCTION THEREOF         Novel platelet-derived growth factor (PDGF) analogs are provided in accordance with the present invention.  Also provided is a method for the production of homogeneous quantities of these novel analogs.  The novel analogs of the present invention, when refolded, have substantially the same biological activity as naturally occurring PDGF B109.  The method of the present invention employs the use of a stop codon on the c-sis gene, or other coding sequence for a precursor protein of PDGF B109, or analogs thereof, at a position corresponding to a location from about amino acid 111 to about amino acid 160.  The method of the present invention results in the production of relatively large homogeneous quantities of recombinant PDGF B analogs from high expression host cells, such as E. coli.

Title: Process and device for making a product comprising a support including a prolonged effect adhesive and a protective band
Inventor: CHEVALIER PIERRE A M
IPC: B31B50/62
Filed: 1990-06-28
Abstract: The process is designed to manufacture a product consisting of a backing (20) with a long-lasting adhesive (2-10) and protection tape (15) for delayed use of the adhesive (2-10).  The product may be characterized as follows.  The backing (20) including one face (22) receiving the adhesive (2-10) exhibits irregularities.  The adhesive (2) is heated to a temperature at which it becomes pasty at the limit of the liquid state and is conducted to at least one hole (4) over a plane (5) on which the backing (20) is placed.  Flow is produced at the same time as relative movement between the backing (20) and the hole (4) so that the adhesive (2) is deposited on the backing (20) in at least one continuous thick bead (10).  The temperature of the deposited adhesive (2) is lowered to increase its viscosity until it is pasty at the limit of the solid state.  Pressure is exerted on the pasty adhesive (2-10) in order to produce lateral spreading and laminating of the bead (10) over its entire length.  Then the product, consisting of backing (20), a strip of adhesive (10) and a protection tape (15), receives at least one subsequent cut.  See Figure II.

Patent CA-2044478-A1 (CA)
Inventor: MURRAY JOHN R
IPC: B61D7/28
Filed: 1991-06-13
Abstract: A door apparatus for a railway hopper car for discharging bulk material from the car has an elongated flexible hollow body positioned in a discharge opening.  A pair of end walls are attached to opposite ends of the body. Each end wall has a first pivot point for rotary attachment to the body.   The body is rotatable about the first pivot point between an opened position and a closed position. The body has an arcuate surface extending generally vertically when in the closed position to reduce the effort required to open the doors when the car is loaded.  If the door apparatus is stuck in the closed position, such as when ice has formed between the longitudinal edge of the door apparatus and the edge of the discharge opening, a torque applied to one end of the door apparatus about the first pivot point tends to twist the door apparatus about the longitudinal axis.

Title: Electric motor with reduced coil content
Inventor: BURNS WILLIAM
IPC: H02K1/14
Filed: 1991-08-22
Abstract: ABSTRACT OF THE DISCLOSURE            A switched reluctance motor has a stator assembly with an annular yoke and inwardly directed stator poles. A rotor assembly within the yoke includes rotor elements with which the stator poles register simultaneously and repeatedly with each complete rotation of the motor shaft supporting the rotor assembly. The stator poles are arranged in sets of two or more poles, each surrounded by a single elongate, ring-like, planar coil. In each pole set, the circumferentially extreme pair of stator poles are shaped to define a pair of parallel surfaces that engage opposite ends of the coils. The stator yoke also defines a pair of internal flat coplanar surfaces associated with each pole set. These yoke surface seat the opposite ends of the coil associated with the pole set. The axial lengths and relative spacing of the stator poles are such that the material content of each coil is reduced compared to conventional multiple coils individually wound on individual poles.
