Title: IC engine carburettor unit with resistance element - incorporates heating device with several heating passages to improve fuel vaporisation (NL 13.3.78)
Inventor: MARCOUX LEO
IPC: H05B3/14
Filed: 1977-09-09
Abstract: The carburettor unit includes a fuel/air channel with an air inlet leading into this channel and a fuel inlet also leading into the channel to mix the fuel with the air inside the channel. An outlet from the channel is supplies unit a mixture of air and vapourised fuel. The unit includes a heating device with an element made from electrically resistant material with a positive resistance temp. coefficient. The element has several heating passages in an arrangement next to each other extending between opposite ends of the heating device and through it. Thus several stays of resistant material are produced between the heated passages. There is also a connection between the fuel-air mixture and the resistance element to facilitate the fuel vaporisation.

Title: Forming pipes from extruded synthetic profiles - on installation permitting wide ranging variation of traversing belt and spindle speeds
Inventor: BANDERA LUIGI
IPC: B29C53/74
Filed: 1978-06-02
Abstract: The velocity of the endless belts running axially on the surface of the rotating spindle of a machine for the production of pipes from extruded profiles of synthetic material can be varied by means of a multi-speed gearbox. The hot extrusion is wound on the belts which are driven by gear wheels supported on details rotating with the spindle. The spindle has a journal assembled detachably to a disc which forms the support for the belt roller brackets. The speed of revolution of the spindle can also be varied. Process makes it unnecessary to dismantle the bell spindle and replace it with another when it is desired to change over to extruded profiles of a different breadth. When the speed of the bands is adjusted to the new conditions no other setting is necessary. The belts and the spindles are driven separately.

Title: Windscreen wiper with retracted parking setting - has servo drive for instant lift from park position
Inventor: BERGER JOSEF
IPC: B60S1/18
Filed: 1978-09-15
Abstract: The modified wiper drive has the wiper stub in a pivotted support (7) whose angle is set by a simple servo motor (11) linked to the main wiper supply. The servo motor operates the tilt action of the support and causes the wipers to assume a recessed park setting at the end of the wipe action. The wipers are immediately lifted out of the park setting when switched on. This provides an instant wipe so that the driver is able to clear the windscreen rapidly, such as when the screen is suddenly obscured when overtaking.

Title: Laboratory heating element - with centre of tubular spiral attached to moving arm for adapting to non-planar shape of vessel bottom
Inventor: LANGER ALFRED
IPC: B01L7/00
Filed: 1978-10-09
Abstract: An electrical heating element consists of a tubular spiral coil which is normally disposed in a horizontal plane to heat beakers and other laboratory vessels with plane bottoms. The element rests with its outer turn on a stand but the smallest turn inside is attached to a cross arm which can be moved downward by turning the knot on a leadscrew. This gives the element a spherical contour which can be matched to the bottom of spherical glass retorts and similar vessels. Such a heating element saves energy and reduces the time required to heat the various shapes of laboratory glass vessels.

Title: Jet dyeing of natural and synthetic yarn - using kinetic energy of gas, esp. steam from jet for transport
Inventor: ELTZ HANS-ULRICH VON DER DIPL
IPC: D06B3/28
Filed: 1979-02-17
Abstract: Dyeing of natural and/or synthetic yarns with suitable heat-fixable dyestuffs in jet dyeing plant involves heating the yarn to the dyeing temp. with steam in a closed vessel, then introducing all the dye liquor at the dyeing temp. under steam pressure and circulating the liquor and yarn under isothermal conditions. The improvement is that the kinetic energy of the tangential gas (steam) stream from a jet (combination) is used for transporting the yarn in or through the plant. Difficulties associated with transport using the liquor only are overcome and it is possible to fill the plant with yarn without liquid (pretreatment bath). Rapid heating is achieved.
