Title: Crystalline polyphthalamide composition having improved heat resistance properties
Inventor: BROOKS GARY T
IPC: C08K3/16
Filed: 1990-04-24
Abstract: Improved polyphthalamide compositions which possess desirable heat resistance properties comprise a crystalline polyphthalamide component, reinforcing fibers, and a particulate thermotropic liquid crystalline polymer component in an amount sufficient to nucleate a melt of the polyphthalamide. Molded articles prepared from these compositions exhibit excellent mechanical and thermal properties, including especially high heat deflection temperatures, even when molded using molds heated below Tg of the polyphthalamide component, often facilitating molding using steam or hot water-heated molds.

Title: Process and installation for the rearrangement of articles palletised according to sorts to form groups of specific sort composition
Inventor: FOCKE HEINZ
IPC: B65G47/31
Filed: 1990-04-30
Abstract: Process and installation for the rearrangement of articles palletised according to sorts to form groups of specific sort composition Abstract For the rearrangement of articles of different sorts, which are deposited according to sorts on pallets, to form groups of articles of a plurality of sorts, each deposited on a base, pallets of the different sorts of articles  are  depalletised  continuously  in  layers  by delivering  the  depalletised  articles  to  individual conveying means, whence the articles are transferred to a sort-conveying means intended for the particular sort of article and with an associated sort store and are intermediately stored in the latter (that is to say, according to sorts).  Subsequently,  the intermediately stored articles are discharged from the sort stores by means of the respective associated sort-conveying means in the number and sequence required for forming a group, and are fed to at least one group-forming station and in this are deposited on a base in the desired arrangement within the group to be formed.
Patent CA-2016349-A1 (CA)
Title: Powder transport, fusing and imaging apparatus
Inventor: BUCHAN WILLIAM R
IPC: G03G15/16
Filed: 1990-05-09
Abstract: Abstract A transport member moves in a cyclic path to carry material from a first location to a second location at a different temperature, and counter-moving portions of the member exchange heat with each other along an intermediate portion of the path, so that minimum energy is lost to the environment.  In one embodiment as a printing apparatus, a belt transports a heat-fusible toner to a heated location where it softens and is transferred by pressure as a print image to a sheet.  Effective powder pick up and release is obtained in the printing apparatus with a transport member having an elastomeric base layer of a sufficient softness to conform to a rough member such as paper, and a non-tacky outer coating which is harder than the elastomeric layer.  The outer coating has a low surface free energy, and is thin enough to conform, but hard enough to prevent entrainment of toner particles.  A dielectric filler adjusts both the capacitance and the hardness of the belt.  This allows a single thin belt to serve as the imaging element, i.e., as the latent and developed image carrier, as well as the element which transfers and fuses toner to a print. A duplex system employs two belt-imaging members which each travel over one of a pair of opposed elastic pressure rollers to deposit a two-sided image on a sheet.

Filed: 1990-06-19
Abstract: ABSTRACT            An advertising display cabinet has a hinged front door comprising a half-silvered mirror.  Behind the mirror is an array of open-fronted cells each containing an electrical halogen lamp.  Interposed between the open front of each cell and the mirror is a light-transmissive picture (printed or photographic).  Photo-sensors disposed behind the mirror respond to diminished incident light caused by the presence of a person in front of the mirror, and activate an electrical controller which thereupon energises in sequence different halogen lamps or combinations thereof in the various cells thereby to cause predetermined back-projected picture images or combinations thereof to be seen by the person in appropriate areas of the mirror.  The controller also activates a tape cassette player so as to provide simultaneously a spoken commentary appropriate to the displayed picture images.  The individual pictures may be replaced by rolls or cassettes from which pictures may be selected in response to signals provided by the controller or cassette player.  The respective cells and associated lamps and pictures may each take the form of a film projector, or an electronic video apparatus, arranged to project a picture image from a film or a video tape respectively directly on to the rear surface of the mirror.

Title: Overturning-preventing device for crane trucks and similar machines
Inventor: MASO ROBERTO
IPC: B60K28/14
Filed: 1990-07-16
Abstract: "OVERTURNING-PREVENTING  DEVICE  FOR  CRANE  TRUCKS   AND        SIMILAR MACHINES"                        Abstract The  overturning-preventing  device  (1)  for  crane trucks  (3)  and similar machines is associated with  the self-propelled  truck  (6)  of the  crane  truck  (3)  in correspondence of the rear axle (8) of the same car,  and is  substantially composed by a pair of plate means  (20, 21) hinged to each other (22) in correspondence of one of their edges. The necessary force in order to generate the rotation  of the plate means (20,  21) relatively to each other is adjustable by means of suitable adjustment means (28, 28A) which influence the minimum load transmitted by the rear axle (8) to the ground.  In case the overturning torque is large,  the rear portion of the  self-propelled truck (6) tends to lift, whilst the rear axle (8), thanks to its own weight,  tends to remain stably resting on the ground,   causing  the  plate  means  (20,   21)  of  the overturning-preventing device (1) to divaricate. Such a divarica-tion is used as a signal for enabling a circuit commanding the load-lifting operations by the crane truck (3) to be discontinued. The overturning-preventing device (1) is also suitable for applica-tion to single-wheel-rear-axle crane trucks, with said rear axle being either of heavy or of light type, as well as to lift trucks.

Title: Machine for intercepting solid constituents in liquid streams
Inventor: GRABBE WOLFGANG
IPC: E02B8/02
Filed: 1991-01-16
Abstract: MACHINE FOR INTERCEPTING SOLID CONSTITUENTS            IN LIQUID STREAMS ABSTRACT OF THE DISCLOSURE         A machine for intercepting solid constituents in a liquid stream, such as sewage, has a frame which carries a downwardly sloping screen positionable in and across the stream so that the liquid flows through but the outer side of the upwardly and forwardly sloping screen intercepts solid constituents.  The screen has a stationary grate with parallel grate bars extending from the lower to the upper end of the screen, and a mobile grate with parallel grate bars which alternate with the grate bars of the stationary grate.  The mobile grate is repeatedly movable forwardly of the stationary grate to lift off the stationary grate bars those solid constituents which were intercepted by the two sets of grate bars, and the mobile grate is then moved upwardly to raise the lifted solid constituents along the outer side of the stationary grate prior to redepositing the lifted constituents on the stationary grate.  The mechanism for repeatedly moving the mobile grate employs a gearmotor and a parallel motion which is composed of followers movable along stationary tracks at the lateral sides of the screen and levers which are coupled to the mobile grate and to the followers and one of which receives motion from the motor.  Alternatively, the levers are pivotable by a parallel motion which is driven by the motor by way of a crank or a feed screw.

Title: Compact safety belt retractor
Inventor: ZYGUTIS JAMES L
IPC: B60R22/40
Filed: 1991-01-18
Abstract: ABSTRACT          A compact safety belt retractor is provided with a large coil of webbing on a rotatable reel and locking pawl teeth are able to have locking engagement with toothed wheels on the reel even when the coil of webbing has a larger diameter than the diameter of a circle defined by the teeth of the ratchet wheels.  The coil of webbing preferably extends the full depth of retractor from front edges of the sidewalls of the frame to the rear frame wall of the retractor.  Thus, a large coil of webbing may be stored for the depth of the retractor.  To reduce the side-to-side width of retractor, it is preferred to have reel ratchet wheels mounted in the plane of the frame sidewalls and to have the pawl teeth also mounted in openings in the sidewalls of the retractor frame.  The pawl teeth are elongated columns and are loaded in columnar manner with substantially small shear or bending tresses thereon.  At very high loading on the belt, as at the time of accident, the reel may deflect to  shift the toothed wheels to directly engage the bearing surfaces on the sidewalls of the frame when the reel is locked.  Both the locking pawls and the toothed wheels are substantially coplanar with the sidewalls of the frame and are disposed within openings in the sidewalls.
