Patent CA-2129275-A1 (CA)
Inventor: SPENCER WILLIAM W
IPC: B60G11/36
Filed: 1994-08-02
Abstract: A vehicle supplementary spring assembly is adapted to supplement the spring force provided by a leaf spring of the vehicle. The spring assembly includes an elongate coil spring which forms an axially extending passage having a wall of helical configuration defined by the inner surface of the coils of the coil spring. A first anchoring insert is configured to be in threaded engagement with the wall of the passage and is adapted to be screwed into one end of the coil spring. A first connector member is connected to the anchoring insert and is adapted to connect the supplementary spring assembly to a first reaction point on the vehicle. A second connector member is connected to the other end of the coil spring and is adapted to connect the supplementary spring assembly to a second reaction point on a vehicle. The first and second reaction points are selected in use such that a tensile force applied between the reaction points will supplement the action of the leaf spring in supporting the vehicle, said supplementary spring assembly being adapted to apply a tensile force between said first and second reaction points, said tensile force being selectively variable by varying the position of the anchoring insert along the length of the passage.

Abstract: 2129640 9315963 PCTABS00024 A plastic dispensing closure including a closure body (102), a lid, a resilient ''living'' hinge (106) joining the lid to the closure body, and camming members (118, 114) defined between the lid and the closure body to temporarily deform the hinge, within its elastic limits, as the lid is moved between its opened and closed position. One end of the hinge (106) is secured to a flexible holder (120) situated at the rear of the closure. Such holder (120) functions as a cantilever beam and serves as a spring to minimize the stress forces imposed upon the ''living'' hinge. The closure body, lid, and hinge may be integrally molded, and the holder (120) may be situated upon the closure body (Fig. 13), or upon the lid (Fig. 15) as design considerations dictate.

Title: Solid elastomeric block copolymers
Inventor: COOLBAUGH THOMAS S
IPC: C08F236/04
Filed: 1993-02-17
Abstract: There are disclosed novel, solid, elastomeric block copolymers with improved resistance to cold flow wherein either 1) the terminal blocks are each a polymer (I polymer) of at least one conjugated diene (I), e.g., isoprene, which contains at least five carbon atoms with at least one of each pair of double-bonded carbon atoms in the polymerized diene I units being additionally single-bonded to two carbon atoms; at least one middle or interior block is a hydrogenated polybutadiene (B polymer); and at least one middle or interior block is an essentially straight chain polyethylene (E polymer) resulting from the hydrogenation of a polybutadiene composed of at least 80 % of 1,4- units; or 2) the terminal blocks are random copolymers resulting from the hydrogenation of a copolymer of at least one diene I as previously defined and hydrogenated butadiene, and at least one middle or interior block is a straight chain polyethylene (E polymer) as previously defined. The hydrogenated butadiene units in the B polymer or random IB polymer blocks are composed of no more than about 65 % of 1,4- units and at least about 35 % of 1,2- units. The foregoing block copolymers may be prepared by selectively hydrogenating substantially all the butadiene units of a precursor block, copolymer wherein the precursor blocks of the straight chain polyethylene block units are polybutadiene blocks in which at least about 80 % of the butadiene units are 1,4- units. A sufficient number of I units in the I  polymer blocks or random IB copolymer blocks retain their unsaturation on selective hydrogenation to enable the vulcanization of the block copolymer.

Title: Method and device for processing free-flowing materials
Inventor: KOENIG HERIBERT
IPC: F27B3/08
Filed: 1993-01-06
Abstract: Abstract The invention is directed to a method for processing free-flowing materials, in particular filter dust from industrial metallurgical waste and domestic waste incineration plants, and to a device for carrying out this method. In order to ensure that the end product can be reused or can be disposed of in an environmentally sound manner, the following steps are carried out: the free-flowing material is mixed in the dry state with a reducing agent; the mixture is inserted through the bore of at least one hollow electrode in a metallurgical vessel, the electrode being immersed in the slag located in the vessel, and is applied to the surface of the slag and injected into the molten slag pneumatically; heat is supplied to the mixture during the reaction between the mixture and the slag; evaporating components in the mixture are sucked out above the surface of the slag; components sinking into the slag are tapped together with the slag and the remaining components of the mixture remain in the slag and are discharged along with the slag. The bore of the hollow electrode is connected with a device (50) for feeding and discharging gaseous media. The power supply (30) has elements for maintaining constant current (36) and for regulating the electrical output (37).            (Fig 1)

Title: Multiple package forming and filling machine
Inventor: GENTILE ALISEO
IPC: B65B3/02
Filed: 1993-04-09
Abstract: A machine for and a step by step method of forming packages (61) or containers from blanks (48), heat seating (94) the sides of the packages (61) and depositing the packages in fixtures (112), retaining the packages in fixtures during closing of the packages with product, heat sealing the tops (178) of the packages and ejecting the packages from the fixtures. The sides of a newly formed package are heat sealed through apertures (98) in the forming die (86) before the package is placed in the fixture. Once placed in the fixture at tha forming station (26), the package remains in the fixture during the filling oe dosing of product at the filling station (28) and as indexed into the top sealing station (30). At the top sealing station the filled package is partially elevated from the fixture to expose the entire top of the package for heat sealing. At the filling station a manifold (120) supplies a plurality of flexible tubes (124) leading to a plurality; of bellows type reciprocable dosing pumps (126).    The dosing pumps in turn supply product through flexible tubes (128) to filling tubes (130). Any parts through which product passes are simply connected requiring no tools for disassembly or assembly. The parts that contact product and are plastic are merely discarded. The parts that contact product and are metal are easily cleaned. Thus, the machine can be easily thoroughly cleaned when product changes are made.

Title: Micro particles
Inventor: OTTERSTEDT JAN-ERIK
IPC: C01B39/52
Filed: 1993-09-01
Abstract: The present invention relates to colloidal suspensions of discrete particles of colloidal zeolite and a method for preparing such zeolite from clear tetraalkylammonium stabilized aluminiumsilicate solutions. Smaller amounts of well defined and con-trolled metal hydroxide solutions are added to these alumiumsilicate solutions to enable the synthesis of a specific zeolite as well as to control zeolite yield. The colloidal suspensions are characterized by an average particle size of less than 250 nanometers and preferably, less than 200 nanometers together with the fact that the particle size distribution expressed as the geometric standard deviation is less than 1.30 and preferably less than 1.20. Zeolite sols synthesized according to this invention display Tyndall light scattering typical for colloidal suspensions as well as a very low rate of sedimentation due to the small particle size. Zeolite sols synthesized according to this invention can be prepared so as to contain negligable amounts of amorphous material.

Title: Apparatus for locating buried conductors
Inventor: DOANY ZIYAD H
IPC: G01V3/10
Filed: 1994-01-14
Abstract: An apparatus for locating obscured conduits (28), such as buried cables, employs a novel signal processing technique to increase the sensitivity of the apparatus, particularly in congested areas. The cable locating apparatus (10) is similar to prior art dual-peak detection devices which compare signals from two parallel induction coils (12, 14), but a phase shift is introduced into one of the signals prior to the caparison. This phase shift serves to minimize the effects of said minima in the response curve of prior art dual-peak devices. This effect is enhanced by adding a gain mismatch to the two detected signals. The locator (10) preferably operates with analog signals to reduce expense.
