Title: Pumps
Inventor: BOOTH RAYMOND I
IPC: F04D29/22
Filed: 1991-09-23
Abstract: A pump (10) comprises a hollow cylindrical body (12) open at one end. A central hole (14) is provided through the closed end of the body (12) with a perimeter wall (16) around the hole (14) of the same height as the boundary wall (18) of the body (12). A left hand thread (22) is provided around the wall (16) and a right hand thread (24) is provided on the inside face of the wall (18).  First and second components (26, 38) are provided rotatably mounted respectively on the threads (24 and 22). The components (26, 38) comprise a planar base (28, 40) with upstanding blades (36, 42) thereon. The blades (36) on the first component (26) are orientated for pumping when the rotor turns in one direction and the blades (40) on the second component (38) are orientated for pumping in the same direction when the rotor turns in the opposite direction. The first component (26) is provided with an opening (30) through which the second component (38) can slidably pass in an axial direction such that rotation of one of the components (26, 38) causes rotation of the other component, with one component rising relative to the body to an operative position with the blades thereon extending above the body for pumping when the rotor turns in one direction and the other component descending into the body, and vice versa.

Title: Front jaw
Inventor: WAWRA REINHOLD
IPC: A63C9/08
Filed: 1992-03-25
Abstract: Abstract The invention relates to a front jaw (1) comprising a housing (2), in which is housed a release spring (40). Same loads a pull rod (10) extending through it, which pull rod acts through a release plate (13) onto the shorter lever arms (36) of two toggle levers (35) which are pivotal about vertical axes (34) on a support part (20), and the longer lever arms of which are designed as sole holders (37).  The support part (20) has an opening (21) for the pull rod (10) and has a front support surface (23) which partly rests on a rear crosswall (3) of the housing (2).    In order to protect such a front jaw (1) against the penetration of snow and dirt on the side facing the shoe, the invention provides that on the housing (2) on the side facing a ski shoe there is arranged a path-defining means (8) for the release plate, and that an approximately vertically upwardly extending cover plate (80) is connected to the path-defining means (8), the upper end section (81) of which cover plate is bent forwardly at least in certain areas.  It is furthermore important according to the invention that an open area (90) permitting the movement of the release plate (13) is formed between the cover plate (80) and the release plate (13).

Patent CA-2099282-A1 (CA)
Inventor: MASTERSON BRIAN K
IPC: G01N35/10
Filed: 1992-10-27
Abstract: A system (10) for processing a specimen to which fluid must be added includes a fluid dispensing work station (16) within a housing. The work station (16) holds the fluids that are to be added to the specimen. A nozzle (148) dispenses fluid at the work station. The system (10) also includes a carrier (24) that moves within the housing. The carrier (24) operates in a first mode at the fluid dispensing work station (16). The carrier also operates in a second mode outside the work station (16) to perform a different processing function. A coupling mechanism (170) attaches the nozzle (148) to the carrier (24) when the carrier (24) enters its first operational mode to transport the nozzle (148) around the fluid dispensing station (16). The coupling mechanism (170) releases the nozzle (148) from the carrier (24) when the carrier (24) enters its second operational mode, thereby freeing the carrier (24) for movement outside the work station (16) out of association with the nozzle (148).

Abstract: A finely divided chloride process titanium dioxide prepared without the use of a dispersing agent.  The slurry is dewatered via filtration, and the resulting filter cake is made flowable with an anionic dispersing agent.   In order to  attain  a  filter  cake with  very  high  solids content, the slurry should contain no, or only very few, multivalent anions.  The conditions regarding the content of  multivalent  anions  of  the  slurry  are  achieved  by selection of suitable dechlorinating agents,  especially hydrogen peroxide.  The filter cake is thixotropic and is made flowable by the fact that it is put into the "diluted" dispersing agent, especially into a part of the titanium dioxide  suspension  to  which  the  required  quantity  of dispersing agent has previously been added.   Titanium dioxide suspensions with solids content of approximately 78% are thereby obtained and are of particular use in the paper industry.

Abstract: DUAL BEAD DIAMETER TIRE                          ABSTRACT A pneumatic tire having two different bead diameters has handling, ride and treadwear advantages. The tire is made so that the rhom of the longer sidewall and the rhom of the shorter sidewall are equal.  The rhom of the longer sidewall is made equal to the rhom of the shorter sidewall by establishing a belt profile wherein the amount of drop at a belt edge is specified to give a mold drop of 0.30 to 0.33 of estimated tire deflection, applying an inflated shape prediction formula to calculate the inflated belt profile and varying the value of rhom until the drop at the end of the belt closely matches a specified value, using the cosine law to specify the change in belt angle with radius, choosing a shoulder point under the belt edge that allows a 0.050 inch wedge between the bottom of the belt and the top of the carcass ply and varying the slope of the ply at the shoulder point until the inflated ply line passes through the Y-max location at rhom.

Abstract: ABSTRACT    The storable modular component, especially a storable glass module, is prepared for assembly by gluing to another component without using an additional assembly glue.  Along its edge it displays a profiled bead of a latent reactive adhesive which includes predominantly one or more polyurethanes with blocked isocyanate groups, or one or more polyurethane preproducts consisting of polyols and/or polyamines and encapsuled polyisocy-anates, or one or more polyurethanes with radically polymerizable groups.  In this case the reaction of the adhesive can be initi-ated at an activation temperature of 70 to 180°C.  At the same time, it remains tacky and nonflowing but plastically deformable for a time sufficient for assembly.  The stated materials are capable of being activated by being supplied with electrical, electromagnetic or magnetic energy or by infrared radiation.  The adhesive may contain magnetizable and/or electrically conductive fillers.  The glass module is used for direct glazing of vehi-cles, especially automobiles.
