Title: Gas lift system
Inventor: BOBO ROY A
IPC: E21B43/29
Filed: 1987-10-21
Granted: 1990-12-04
Abstract: ABSTRACT                        GAS LIFT SYSTEM      The method of the present invention relates to a gas lift operation wherein pressurized injection gas is mixed with pressurized injection liquid prior to introducing the pressurized mixture into a borehole.  The pressurized injection gas and liquid mixture is introduced into one portion of the well bore to a point below an initial column of well fluid present in another portion of the well bore conduit.  As the mixture of injection gas and liquid travels towards the bottom of the well bore the gas is compressed more and more by the height of the column of liquid thereabove and is subsequently passed to said another portion of the well bore where the gas rises and expands to lift the oil or other well fluid to the surface.  As a result of the expanding rising gas in the production conduit and the lifting of the initial charge of well fluid in the production conduit, the pressure at the lower end of the production conduit adjacent the producing formation drops, thereby inducing additional well fluid to enter said another portion of the well bore from the formation.  Further injection of pressurized injection gas and liquid lifts any additional oil or other well fluid emerging from the formation to the surface.

Granted: 1992-04-28
Abstract: ABSTRACT OF THE DISCLOSURE                    TRANSFER ROLL SYSTEM          A transfer roll for transferring a strip com-ponent from a conveyor to a tire building drum has an outer rim member rotatably mounted on a cylindrical ring member  which  is mounted  on  an  inner hub for movement relative to the tire building drum.   A pair of piston-cylinder assemblies control the movement of the cylindri-cal ring member to press the outer rim member against the strip component on a tire building drum.  The outer rim member is rotated by a motor mounted for movement with the cylindrical ring member and the amount of rotation is controlled by control means including an encoder mounted for movement  with  the  cylindrical  ring member  and  in engagement with the outer rim member.   A pair of the transfer rolls may be mounted on a shaft with means for adjusting the distance between the rolls after the strip components are transferred from the conveyor to the rolls in  a  conveyor  position  and moved  to  an  intermediate adjusting position.  Several sets of vacuum cups are pro-vided around the circumference of the transfer rolls and each set has a separate vacuum pump to retain the strip component on the outer rim member.

Abstract: ABSTRACT OF DISCLOSURE    A glass bottle forming system is described in which a main glass melter is connected to a forehearth with a fairly conventional feeder provided at the delivery end of the forehearth.  The feeder opening in the bottom of the fore-hearth is closed by a first orifice member through which a molten core glass will flow.  Beneath the first orifice there is positioned a second orifice member that has an orifice that is slightly larger than the orifice in the first orifice member.  A small melter contains a glass of essentially the same composition as that in the main melter, but with a coefficient of expansion slightly less than that of the core glass.  This lower expansion glass is fed to the second orifice member so that it can flow out of the orifice with the core glass in surrounding relationship with respect thereto.  The skin glass melter is connected to the second orifice member by a gravity feed system in which the connection is thermally controlled so that the viscosity of the two glasses are maintained essentially the same.  Two embodiments of the skin melter and the second orifice are disclosed.  In one embodiment the second orifice is vertically adjustable so as to vary the volume of skin glass flow relative to the core glass flow.  The second embodiment has the second orifice supporting an annular bushing that is vertically adjustable and it cooperates with the bottom of the upper orifice member to regulate the flow of glass into surrounding relationship to the core glass coming through the first orifice member.

Title: Method and apparatus for removing iron from well water
Inventor: HOUSER STAN
IPC: C02F1/64
Filed: 1988-05-04
Granted: 1993-08-24
Abstract: ABSTRACT       A method of removing iron from ground water located in a water well includes positioning a bubbling device in the well below the waterline.          This device, which is connected to a source of pressurized air, is operated to produce a continuous flow of air bubbles in the water to render dissolved iron in the water insoluble so that the latter precipitates out.  The insoluble iron can then be gathered from the well periodically.  In one version, an iron collecting device in the form of a bag is placed around the bubbling device.  The bag is removable from the well in order to remove and dispose of collected insoluble iron.  Calcium carbonate can be used to adjust the pH level to pH 7.  The bubbling device can be additionally advantageous when introduced into water containing sulphur.  The air stream of bubbles then has a double action and produces no hydrogen sulphide.

Title: Hearing aid comprising a printed circuit board and hearing coil
Inventor: ERBE EHRENFRIED
IPC: H04R25/00
Filed: 1988-06-24
Granted: 1992-02-25
Abstract: ABSTRACT OF THE DISCLOSURE         The hearing aid has a flexible printed circuit film having a printed circuit wing bent around a rounded portion, and also has a hearing coil.  In order to save space, the hearing coil is preferably divided into two smaller, series-connected coil windings.  These can be symmetrically arranged in the hearing aid housing.  Since the bending coinciding with the rounded portion is not suitable for the contacting of components, the hearing coil is radially arranged thereabove in a protective member.  An even more space-saving arrangement of the components in the hearing aid housing thus results.

Abstract: ABSTRACT OF THE DISCLOSURE:         Retention  mechanism  for  a  safety-belt  band adjustable manually and adapted to be fastened to a part of a vehicle structure and consisting of a body with a base and mounts for anchoring the base to the part of the structure. A hand support has a reinforcement and an aperture and  is movably connected to the body to adjust the position of the safety belt band.  The base and the anchoring mounts of the body are arranged so as to form a recess at the rear of the base, the body further including a guide in line with the recess and equipped with at least two cells, with each of which a stay is associated.  At least one spring generates a force in line with each cell and in the direction of the latter.  The band support is movably connected to the body in such a way that the base  and the guide of the body passes through an aperture of the support and in such a way that the reinforcement of the support can engage into a cell and rest against a stay or travel in the recess, the force generated by the spring normally pushing the reinforcement into the cell.
