Title: Apparatus for cleaning pipes and tapping installations for beer and other pressurized liquids
Inventor: GRUFFY GEORGES
IPC: B08B9/04
Filed: 1979-05-14
Granted: 1983-03-24
Abstract: 1. A device for rinsing the pipes used to draw beer from pressurized kegs, consisting of a machine metal body, item 1, in the form of a hollow T. One end of the T cross-branch, item 10, is connected to the keg outlet and contains a non-return ball-valve, item 7. The other end of the T cross-branch, item 3, is connected to a water supply and contains a second non-return valve, item 5. The leg of the T, item 11, remains open and is connected to the beer serving tap pipe. The invention is characterized by the fact that the ball, item 7, opening pressure is controlled by a spring, item 6, and that the second non-return valve, item 5, is in rubber and includes an annulus which forms the seal between the body, item 1, and a union, item 2, and a central section which forms the non-return valve proper ; this combination allows the rinsing operation to be controlled simply by opening the water tap ; no other operation is required on the device itself.

Title: Automatic device and process for tightening and untightening a nut on a tension bolt
Inventor: BOUDET GEORGES
IPC: B23P19/06
Filed: 1979-09-24
Granted: 1984-05-03
Abstract: Stud bolts are threaded into the body of a nuclear reactor vessel and tensioned by exerting forces on tensioning nuts located on the upper end of the studs. While the studs are under tension, a cover is attached to the vessel by tightening nuts on the studs against the cover. The tensioning nuts are applied to the studs by immobilizing the studs axially and rotationally, and rotating the tensioning nuts with a pair of driven, diametrically opposed striking rollers. External threads on the striking rollers, external threads on the nut and internal threads on the nut all have the same pitch so that the threads on the striking roller remain engaged with the external threads on the nut as the nut moves axially while being threaded onto the immobilized stud.

Title: Mattresses
Inventor: PATERSON JOHN KIRKPATRICK
IPC: A47C27/08
Filed: 1980-07-21
Granted: 1984-09-20
Abstract: A mattress having at least one fluid-tight envelope enclosing a cellular structure whose individual cell volume is relatively-large (typically from 120 to 20,000 cm<3>), adjacent cells communicating with one another by means of perforations permitting a limited rate of flow of fluid between the cells. Typically the fluid is air which inflates the envelope to 10-50 KPa above atmospheric pressure. Preferably a mattress cover fits around a plurality of generally elongate cores, each core constituting a said gas-tight envelope. Typically six generally parallel-extending cores are employed for a standard double-size mattress and four for a single mattress. The envelopes may be fitted with air-valves to enable inflation to be conducted conveniently in the home. Different cores may be inflated to different pressures in accordance with comfort.

Title: Tampon for feminine hygiene and method of making it
Inventor: SUSTMANN SCARLET DR
IPC: A61F13/20
Filed: 1983-09-24
Granted: 1987-04-09
Abstract: A tampon for feminine hygiene consists of a cylindrically-compressed length of a strip of cottonwool or rayon staple or a combination thereof which is wrapped with an overlap in a fluff-free or fuzz free covering material, said strip being cut into the required lengths together with the covering material perpendicularly to the overlap line, and a recovery thread attached to the length of a strip of cottonwool or rayon staple or a combination thereof. The problem which the invention solves is to prevent fibers from breaking loose from the exposed cut edges. According to the invention, the exposed cut edges are folded onto the surface of the length of a strip of cottonwool or rayon staple or a combination thereof after it has been separated and compression is carried out in such a way that the exposed cut edges are situated inside the tampon.

Granted: 1988-08-18
Abstract: An angiographic syringe (12) and a connector (14) for effecting the connection of a catheter (16) to the syringe (12) is disclosed. The connector (14) is a tubular member that engages the syringe (12) at the discharge end and removably engages a suitable end member of a catheter (16). In the preferred embodiment, the connector is a hollow single-piece structure with tabs (40) at one end for engaging the discharge end (38) of the syringe.
