Granted: 1993-05-11
Abstract: ABSTRACT OF THE INVENTION      A unit for use  in a tub or spa to provide a dry hydro-massage of the neck and shoulders.  The unit mounts to the tub edge and includes a diaphragm which sealingly covers a discharge jet such that the fluid will flex the diaphragm into massaging relationship with the user's body.  The water is exhausted into the tub through a secondary port below the water line such that dry hydro-therapy is provided by the unit.   The  inflation of the diaphragm  is controlled by pressure  regulating  ports  formed  within  the  housing  to control the exhaust of fluid from the jet chamber. In one embodiment,  the ports are variable to vary the inflation pressure of the diaphragm.  With the unit mounted to the tub the user may remain seated within the spa while the unit provides a dry hydro-massage of the neck and upper back normally  positioned  above  the  water  line.   To  provide increased freedom of application of the hydro-massage, the unit may be incorporated into a telescopingly adjustable assembly  associated  with  the  tub  wall  or  a  hand-held assembly.

Title: Heater for motor vehicles which can be operated on several power settings
Inventor: REISER PETER
IPC: F23N5/24
Filed: 1989-06-15
Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE      By temperature gradient detection it is determined for the liquid combustion chamber auxiliary heater for motor vehicles, whether e.g. a flame blow-off has taken place, which has to be interpreted  as  a  malfunction  and  which  necessitates  the discontinuation of fuel supply.  Alternatively, it might merely show the switching from a high setting to a low setting.   In the latter case a temperature drop to a lower operation temperature occurs also.  However, the temperature drop is not as steep as in the case of a flame blow-off.  At certain points in time t1 the target temperature for a point in time  t2 is calculated by the detected temperature according to a certain algorithm having specific device properties as parameters.  At this point in time the calculated target temperature is checked for errors.

Title: T-bar wall connector
Inventor: COBB BILL
IPC: E04B9/00
Filed: 1989-09-28
Granted: 1993-04-20
Abstract: ABSTRACT OF THE DISCLOSURE           When constructing walls beneath suspended ceilings of the type including T-bars, the usual practice is to connect C-shaped channel members directly to the T-bars.  If the walls are disassembled or moved, unsightly holes remain in the exposed bottom surfaces of the T-bars.  A simple connector for solving the problem includes a strip of material which, in use, includes a generally inverted U-shaped central portion for straddling the top stem of the T-bar, and a pair of arms perpendicular to the central portion for extending outwardly beyond the arms of the T-bar into overlapping relationship with the channel member.          Screws are used to connect the device to the T-bar and to the channel member.  Thus, the T-bar remains intact and undamaged.

Abstract: ABSTRACT OF THE DISCLOSURE           Predetermined limits are attained for the peak loads encountered when a composite assembly of workpieces is secured with a swaged collar fastener, by disposing cavities in the cylindrical wall of the fastener collar to receive material flow during the swaging operation.  Rotation between the collar and pin of the fastener is precluded by disposing abutting portions on the pin, which interface against the swaged material of the collar.  Fastener cost reductions are achieved by decreasing the volume of a post-swage scrap portion on the pin and by concurrently fabricating grooves thereon with a rolling die, for various functional purposes.  Swaging tool malfunction is avoided by eliminating land surfaces adjacent to grooves on the pin through which pull is applied thereto with the tool.

Abstract: In the paper coating operation a wet or dry edge from coating composition is formed on the, seen in the direction of movement of the paper web, downstream side of the doctor, the so-called stalagmite formation. This stalagmite formation leads to various problems in the papermaking process and especially occurs at high speeds of the paper web and/or a high solids content of the coating composition, which two operating conditions are exactly required to obtain a maximum paper yield and a high paper quality. According to the invention the stalagmite formation is effectively prevented by supplying a fluid inhibiting the stalagmite formation to an area bounded, on the one hand, by the paper web and, on the other hand, by the above side of the doctor blade. <IMAGE>

Abstract: Waste material is sucked away from different suction points (1-8) and is transported in branch conduits (12) to the common collecting point comprising a container (9). The dimensions of the branch conduits (12) and the collecting container (9) are thus chosen that the air velocity in the conduits (12) is sufficient, but in the container (9) insufficient to carry the waste material in the air stream. This will cause the waste material to be extracted in the container (9) and collected in the bottom thereof. The air stream is then passed through a filter (10) before it is returned to the interior space of the building. In the upper portion of the collecting container there are separate openings (11) for the branch conduits (12) connected to the container (9). The lower portion of the container is formed with a funnel-shaped bottom for convenient collection of the waste material. The air flow through the openings (11) in the container (9) or in the branch conduits (12) are controllable by means of individually operated valves (20).

Abstract: POLYURETHANE GOLF BALL COVER            Abstract of the Disclosure A polyurethane covered golf ball is made by allowing the polyurethane cover stock material. to partially cure in an open mold and subsequently molding a golf ball product.  The molding is done by first molding a smooth-surfaced golf ball product in a smooth-walled fixed-pin mold and then, in a second molding step, using a compression mold to impart dimples onto the smooth-surfaced golf ball product.  Between the two molding steps an intermediate curing step is employed.  The initial curing time in an open mold and the intermediate curing time between the two molding steps is minimized through the use of a sufficient amount of catalyst, by keeping the smooth mold at an elevated temperature, or by using the fast-reacting chemical components.
