Title: Lamp sockets
IPC: H01R33/20
Filed: 1979-01-11
Abstract: A socket for a signal or indicator lamp permits the lamp to be replaced from the front and ensures a reliable contacting. In the arrangement shown, there is formed, between a lamp 9 and a sleeve 1, a forwardly-open annular chamber 16 which is closed off at the rear by a collar 12 of the lamp. A forwardly- presented radial annular surface 15 of the collar 12 is forced by a resilient counter-contact 14, from the rear, against the free ends 6', 7', 8' of spring tongues 6, 7, 8 of the sleeve which project into the annular chamber 16. The lamp 9 can be inserted by pushing it in the direction of arrow P whereby first the collar 12 pushes aside the tongues 6, 7, 8, and subsequently the said tongues resile in front of surface 15. The lamp can be removed by pushing a tube into chamber 16 to force back the tongues 6, 7, 8, and then withdrawing the lamp together with said tube. <IMAGE>

Title: Burner
IPC: F23D14/20
Filed: 1979-02-27
Abstract: A torroidal oxy-fuel burner capable of operating on a low pressure natural 985 supply comprises a barrel (101) (Figure 2) having a conical opening (102) and a cone (103) which is disposed in the conical opening and defines one wall of a conical passageway (104) extending between the cone (103) and the conical opening (102). In use, oxygen is passed through the passageway (104) and natural gas is directed into a fuel supply port (202,203) which is disposed radially outwardly of the outlet of the passageway. The oxygen leaving the conical passageway entrains the natural gas from the fuel supply port and forms a torroidal flame downstream of the cone. The burner can be fired on other gaseous or liquid fuels if desired.

Title: A method and an apparatus for cleaning water in a swimming pool
IPC: C02F1/32
Filed: 1980-05-29
Abstract: The water from the swimming pool is circulated through a container divided into a plurality of flow chambers (5, 6, 13) by means of partitions (4) comprising such openings that the water passes through the chambers in succession. In the front chamber (5), bar-shaped heating bodies (7) are located transverse to the flow direction of the water, and in the succeeding chamber (6) ultraviolet radiation lamps (8) are located transverse to the flow direction, said lamps radiating light at  lambda  > 300 nm. In a last chamber (13) ultraviolet radiation lamps (14) are located which radiate light at lambda  < 300 nm. When the water passes through the container (1), skin squames and the like organisms collect on the heating bodies (7), whereas the ultraviolet radiation lamps (8) in the chamber (6) ensure such a disinfection that only a quite small amount of fresh water need to be supplied to the swimming pool. The ultraviolet radiation lamps (14) serve to kill the bacteria resistant to chlorine. <IMAGE>

Title: Double-acting jack
IPC: F15B15/26
Filed: 1980-10-07
Abstract: A double-acting jack has a piston 20 slidable inside a cylinder 11 and a tubular piston rod 40 slidable over a fixed rod 30 supported by the cylinder blind head 12. The piston 20 is connected to the tubular rod 40 by a pair of springs 21, 22 provided one at either side of the piston between respective faces 23, 24 thereof 25, 26 on the outer surface of the tubular rod.
