Patent CA-2006336-A1 (CA)
Inventor: LIBOFF ABRAHAM R
IPC: A61N2/02
Filed: 1989-12-21
Abstract: 2716.013                      ABSTRACT     An apparatus and method for preventing and therapeutically treating osteoporosis arc provided. The apparatus includes a magnetic field generator for producing a controlled, fluctuating, dircctionally oriented magnetic field parallel to a predetermined axis projecting through the target bone or skeletal system. In one aspect, a field detector samples the magnetic flux density along the predetermined axis and provides a signal to a microprocessor which determines the average value of the flux density. The applied magnetic field is oscillated at predetermined frequencies to maintain a preselected ratio of frequency to average flux density which controls osteoporosis. This ratio is maintained by adjusting the frequency of the fluctuating magnetic field and/or by adjusting the intensity of the applied magnetic field as the composite magnetic flux density changes in response to changes in the local magnetic field to which the target bone is subjected.     2716.013

IPC: C08G75/0286
Filed: 1990-01-29
Abstract: Abstract of the Disclosure An  improved  composite  includes  an  improved  polymer, specifically an improved poly(phenylene sulfide).  The improved polymer is produced by an improved method including a polymerization phase, a recovery phase, a washing phase, and an optional air-curing phase.  In the polymerization phase a low temperature cycle and a high temperature cycle are used. In a preferred recovery phase, solidified polymer is quenched with N-methyl-2-pyrrolidone.   In the washing phase,  the recovered solidified polymer is washed with a hot acidic solution and then hot water.   In a preferred embodiment, the method produces substantially linear poly(phenylene sulfide) having a melt flow within the range of about 50 to about 200 grams per 10 minutes and an ash content of not greater than about 0.1 weight percent and a melt crystallization temperature of not less than about 347°F (175°C).

Title: Tee tree fastener
Inventor: WOLLAR BURNELL J
IPC: F16B5/06
Filed: 1990-03-23
Abstract: ABSTRACT OF THE DISCLOSURE A two-way fastener which is adapted for joining at least two members in, electively, either a reusable position or a non-reusable position includes an elongate shank, a head member which is integral with an upper portion of the shank, an elongate rail member integral with and substantially parallel to the shank, the rail member having a substantially tee-shaped cross section, a plurality of non-reusable resilient teeth attached to a side of the shank which is opposite the rail member and a plurality of reusable teeth attached to second and third sides of the shank.  The non-reusable teeth are angled toward the head member at a first angle, and the reusable teeth are angled toward the head member at a second angle which is less than the first angle.  When inserted into a slotted member so that the two sets of reusable teeth engage the sides of the slot, the device acts as a reusable fastener.  When inserted so that the elongate rail member and non-reusable teeth contact edges of the slot, the device acts as a non-reusable fastener.  An additional function of the rail member is than it constrains the fastener against rotation with respect to a slot in which it is inserted.

Title: Molded plastic products having chemically bonded protective coatings
Inventor: MATZINGER JAMES E
IPC: B29L31/30
Filed: 1990-04-03
Abstract: ABSTRACT    Coated plastic products are prepared by chemically bonding a protective coating material to at least a portion of the surface of a plastic substrate, by disposing a web of a protective coating material over the cavity of a mold, and thereafter injecting polymeric precursor materials into the mold behind the web thereby conforming the web to the surface of the mold cavity.  As the polymeric precursor materials react in situ to form the plastic substrate, they also chemically bond to the protective coating material.

IPC: F03G7/00
Filed: 1990-12-04
Abstract: ABSTRACT OF THE DISCLOSURE This pressure wave machine has a cell wheel (2) with a longitudinal axis (3) which is supported in a casing by means of a bearing.  One end face (4) of the cell wheel (2) interacts with a hot gas guidance casing (6)  and the other  (5)  interacts with a gas guidance casing (8) by means of a radially directed sealing gap (7, 9) in each case.     The invention is intended to provide a pressure wave machine (1) whose performance during a cold start is the same as that after the operating temperature has been reached.   This is achieved in that the radially directed sealing gaps  (7,  9)  have at  least one gap extension (20,  21)  inclined to the longitudinal axis and that flanks (22, 23, 28, 29) of this gap extension are located on the generated surfaces of cones which have a common apex on the longitudinal axis (3).

Abstract: ROLL GROOVING APPARATUS                 ABSTRACT OF THE INVENTION    Roll grooving apparatus is pivotally mountable on the support rails of a power drive unit by which the apparatus is driven and comprises a lower support including a drive shaft  driven by  the  power  unit  and  including  the  lower grooving roll, and an upper support member pivotally inter-connected with the lower support member and rotatably sup-porting the upper grooving roll.  A lever arm is pivotally mounted on the lower support member and is interengaged with the upper support member through a pin and slot arrangement, whereby pivotal displacement of the lever arm imparts pivot-al displacement to the upper support member and thus move-ment of the upper grooving roll toward and away from the lower grooving roll.   The  lower  support  includes  a  stop which  limits  displacement of  the  lever  in the  direction which moves the upper grooving roll toward the lower groov-ing roll, thus to assure a desired depth for the groove in a workpiece, and the pivotal interconnection between the upper and lower supports is adjustable to provide for adjusting the groove depth and accommodating different pipe or tube sizes and  thicknesses.   The adjustment  enables  using  the stop on the lower support member as a constant In connection with pipe size and thickness variables and enables optimiz-ing the leverage advantage and the direction of application of force of the upper grooving roll relative to the lower grooving roll.
