Patent CH-669584-A5 (CH)
Inventor: GRUNDER ROLAND
IPC: B65H23/04
Filed: 1986-07-21
Abstract: A web transporting apparatus wherein the web is trained over the external surface of a radially expandible elastic shell which is connected with two end walls to form a roll and to define an internal compartment which is filled with a pressurized hydraulic fluid. The pressure of hydraulic fluid is regulated in dependency upon the thickness of the web which is being transported so that the neutral zone of the web is invariably located at the same distance from the axis of the roll. The pressure of fluid in the compartmnt is regulatable by a hydropneumatic transducer wherein a hydraulic cylinder and piston unit admits pressurized hydraulic fluid into the compartment and the pressure of fluid in the hydraulic cylinder and piston unit is regulated by a pneumatic cylinder and piston unit which receives pressurized gaseous fluid by way of an adjusting valve. Regulation of the outer diameter of the shell compensates for variations in the thickness of the transported web. The material of the shell is selected in such a way that it is capable of undergoing a purely elastic deformation within a desired range which depends upon the range of thicknesses of webs which are to be transported in the apparatus.

Title: Reactor for thermal processing of viscous materials, esp. thermoplastic elastomers
Inventor: NAEF RAINER
IPC: B29C48/67
Filed: 1994-09-28
Abstract: A reactor (10) for thermal processing of viscous materials, esp.thermoplastic elastomers comprises a heated cylinder and/or conical treatment surface (53) and a rotor (15) with conveying elements (7) moving material towards an outlet (22). Shear edges (78) on the rotor (15) are further from the treatment surface (53) than the outer edges of the conveying elements (76).A claimed variation has a rotor comprising two coaxial parts, the outer of which conveys material through an outer chamber from the reactor base to a diverting area and an inner conveys material downwards in an inner chamber from the diverting area to the outlet. A further variation of this type of reactor has shear edges on the rotors further from the treatment surface than the outer edge of the conveying elements.A use for the reactor is claimed in the processing of viscous materials, esp. precondensates of plastics produced by polycondensation

Title: Seat arrangement
Inventor: BREITENMOSER KARL
IPC: A47C1/12
Filed: 1981-05-07
Abstract: The seat arrangement (50) consists essentially of a supporting tube (6), an upright tube (5) arranged coaxially in the supporting tube, and a supporting arm (20) designed to receive a seat panel (45) and secured on the supporting tube. The supporting tube (6), the supporting arm (20) and the seat panel (45) can be swivelled together in the horizontal plane about a first vertical axis (A) from a starting position (G) to an end position (E) or, inversely, from the end position to the starting position, and the seat panel (45) is arranged on the supporting arm in such a way that it can be swivelled in the horizontal plane to a limited extent about a second vertical axis (A') independently of the respective position of the supporting arm (20). In order to achieve an automatic return movement of the parts swivelled about the two vertical axes (A, A'), an appropriately designed and arranged return mechanism is provided in the supporting arm (20). The seat arrangement (50) is suitable in particular for fixed rows of seats, as are installed, for example, in lecture theatres. <IMAGE>
Patent CH-659316-A5 (CH)
Title: Condensate trap
Inventor: MEIER RENE
IPC: F28B9/08
Filed: 1982-05-13
Abstract: This device is installed in the circulation of a solvent preparation plant between a heat exchanger and a vacuum pump. It serves the purpose of collecting liquid condensate upstream of the pump, so that it cannot reach the pump. At the same time, it can also be used, without alteration, in an explosion-proof fashion. The inlet and outlet stubs (2, 3) are arranged in the upper part of the housing (1) in such a way that the loose floating board (4) is held in a position of rest by the vapour current. As condensate accumulates (6), or in the case of intense development of foam during evaporation, the floating ball (4) rises until it is drawn onto the outlet stub (3) by the suction of the vacuum pump. The line is thereby tightly sealed before liquid condensate flows into the pump. The accumulated condensate can flow out via a condensate outlet (7) which can be blocked off by a valve. The floating ball (4) is released by ventilating the system. <IMAGE>

Title: Detection of surface faults in magnetisable material - by applying solvent to ferromagnetic powder coating including pigment and lacquer
IPC: G01N27/84
Filed: 1974-12-10
Abstract: Faults on the surface of magnetisable pieces are indicated by observing the effects on the lines of force of the magnetic field when an electric current is passed through the port. Ferromagnetic powder is used as an indicator. The surface of a piece through which an electric current is passed is coated with ferromagnetic powder in which pigment and lacquer are mixed. This is applied in solid form to the surface and the lacquer is softened by solvent suitable for the piece part temperature. This layer (3) contains a contrasting agent such as titanium dioxide to form a contrast with a second layer (1) containing a fluorescent pigment and glass particles. Faults (2) are visible in the presence of luminous source.

Title: Electrochromatic display device for watches - has large cation admixture to electrolyte for longer life
IPC: G02F1/1524
Filed: 1973-05-21
Abstract: An electrooptical display device, specially for watches, consists of an electrochromatic layer (tungsten oxide) on a transparent conductive substrate, which is separated from a counter electrode by an electrolyte (H2SO4). The electrolyte is treated with a salt which has a cation radius of 1 A or more in the Pauling classification, preferably Ba, added in the form of BaSO4 in a concentration corresponding at least to saturation. This addition prevents the dissolution of the electrochromatic layer which causes the contours of the symbols to become blurred after a certain number of cycles which makes them less legible. BaSO4 is white and increases the rate of colour switch.

Title: Solid material melting appts
IPC: B29B13/02
Filed: 1971-02-12
Granted: 1972-10-06
Abstract: The appts. which is particularly useful in melting a curing agent such as MOCA (RTM) prior to dispensing it into a resin to be cured, includes a vertically disposed hopper, the base of which is formed by an electrically heated member shaped so that material melted upon its surface runs downwards towards its periphery, whence it falls through an annular aperture into a collecting pan form which it may be dispensed. The annular aperture is formed between the rim of the heated member and heated cylindrical flange-like member supported by the wall of the hopper. The upper edge of the flange-like member projects above the edge of the heated member and the upper regions of the member are heated to a lesser degree than the lower regions. In such an apparatus, bridging of the solid material and localised hot spots are prevented and an increased output achieved.
