Title: Arc welding tongs, esp. for joining tubes by butt welding - where arc oscillated across seam by electromagnet fed with voltage pulses of alternating polarity
Inventor: BENAIS ANDRE
IPC: B23K9/08
Filed: 1981-01-16
Abstract: The tongs include an electrode which creates the arc; and also an electromagnet which forms a magnetic field in the plane of the joint line between two workpieces being joined together. The polarity of the electric current supplying the magnet is periodically reversed, so the arc is oscillated transversely across the joint line. The pref. appts. employs an electromagnet with an L-shaped core carrying the magnetic field near to the arc; and the electromagnetic is fed with voltage pulses of alternating polarity. The pulses of one polarity may have a higher voltage than the pulses of opposite polarity so the centre of the oscillations is permanently deflected to one side of the joint line or seam. Usedesp. for joining small dia. tubes, where a filler wire may be fed through one leg of the core of the electromagnet.

Patent FR-2489130-A1 (FR)
Inventor: LEUSCHNER UDO
IPC: A47J31/22
Filed: 1981-08-28
Abstract: The invention relate to a coffee-making machine, in particular an espresso machine, having an outflow channel for the prepared coffee, which leads to two outlets and distributes the coffee over the latter. In this case, the prepared coffee is to be distributed as evenly as possible over the two outlets, and in doing so the foam formed during the coffee preparation is to flow out with it in an unimpeded manner. It is proposed that the outflow channel (26; 426; 626) has a constriction (38; 438; 638), formed by side walls (28, 30; 428, 430), and a transverse wall (44, 46, 48; 444; 644) which divides the jet formed by the constriction into two partial streams to the outlets (40, 42; 640, 642).

Title: Syringe with stops for maintaining intermediate piston level - esp. to sustain suction of plasma sample chamber
Inventor: MESSIER DENIS
IPC: A61M5/315
Filed: 1981-11-06
Abstract: Syringe for use in pulling and maintaining a vacuum in a closed vessel fitted with a rubber cap is provided with means for locking the syringe piston at one or more intermediate positions in the syringe barrel. Used esp. for establishment of a vacuum in a side chamber bounded by a semi-permeable membrane to isolate samples of plasma from blood recirculating through e.g. an artificial kidney, to monitor the purification level. A specific form of the syringe has the piston carried on a rod with radial ribs extending almost to the barrel walls. The barrel wall has 1 or more internal lugs which can be engaged by slots in the piston rod ribs to prevent the piston from shifting unless it is rotated to disengage the lug. Pref. the piston can be arrested at 1 or more levels in a barrel graduated the swept vol. by which the sample chamber has been increased. The lugs may have a tapered end .

Title: Seam welded thin walled tube mfr. - using tube blank with seam gap and controlled welding heat input
Inventor: SHEVAKIN JURY FEDOROVICH
IPC: B23K9/025
Filed: 1981-11-16
Abstract: In the prodn. of longitudinally seam welded, thin walled tube by bending strip to form a tube blank and TIG welding the blank, a gap. of 1/500 to 1/30 of the tube dia. to wall thickness ratio (in mm.) is left between the seam edges of the blank and the welding speed and current intensity are selected to provide a heat input in the welding zone sufficient to close the gap by thermal expansion of the tube blank material and to form a seam weld. Provision of the gap avoids compression of the seam edges in the bending rolls used to form the blank, thus avoiding any risk of buckling or displacement of the edges and damage to or reduction in strength of the metal during welding. Additionally, strips of less precisely controlled width can be used as starting material and the welding speed can be increased.

Title: Thin film lifting and manipulation appts. - has suction head with surrounding support stops on periphery to avoid head-film surface contact
Inventor: MONGODIN GUY
IPC: H01L21/683
Filed: 1981-11-17
Abstract: The appts. has a suction head (1) at the end of a tube (2) fixed on a manipulating arm (3). The tube is connected via a control valve (4) to a flexible pipe (5) leading to a vacuum pump. A number of support stops (6) are arranged in a plane (X,Y) around the suction head and slightly lower than its end piece such that they make contact with the peripheral edges of the film to be manipulated (P). The suction head itself does not make contact with the film, thus avoiding damage to its surface. The support stops may be provided by the bent back ends of arms (7) fixed to the top of the suction head and radiating out around it. The appts. may also have a cylindrical filter around the suction tube to prevent trapping of dust particles. The free end of the filter extends to the same level as the suction head end-piece and does not therefore make contact with the film. To avoid undue deformation of the film several suction heads or a suction head with an annular mouthpiece may be used.

A first wall (23) is attached to two adjacent corner posts. A second wall (24) is attached to one corner post (15) and to the corner post (16) diagonally opposite one of the first corner posts (14). The base (13) comprises 2 longitudinal bars (18,19) and 2 lateral bars (20,21). A second frame has a floor secured to the lower ends of the corner posts and a rectangle (26) secured to the upper portion of the corner posts. The frames are assembled by connecting the corresponding corner posts end-to-end.

Title: Explosion proof plug for liquid electrolyte accumulator - has hollowed section with porous insert capped by porous material with larger pore dia. to minimise leakage
Inventor: LEMOINE ROGER
IPC: H01M2/12
Filed: 1981-11-30
Abstract: The device includes an interior chamber (1) which communicates with the interior of the accumulator through a hole of sufficient dimension to permit the return to the interior of the accumulator of electrolyte which has splashed up into the interior of the cap. The interior of the plug communicates with the atmosphere through a porous plug (5) with pores of a dia. less than that required to allow propagation of a flame through the porous plug. In addition, a main plug (7) has a porous mass (6) between the porous plug (5) and the atmosphere. The porous mass has larger dia. holes than the porous plug, trapping any electrolyte which is splashed by the bursting of a bubble towards the atmosphere.

The internal rim of each channel is clipped mechanically to the perforated outer wall of a tubular filter body packed with a filter aid (activated carbon or clay) held between a pair of annular flange plates with an internal bore skirt to centralise the internal wall of the filter body. A cold-setting adhesive coating resin is pref. used to a melt or a heat cured resin, to reduce overall energy costs and/or thermal damage to the activated filter aids. Refers to possible use of cold-setting polyester or polypropylene ( ) resins for coating the channels to seal the ends of the paper elements. The central flanges are pref. pressed from single sheets of steel about 0.6 mm thick.
