Title: Process for the production of vinyl acetate
IPC: C07C51/235
Filed: 1968-07-03
Abstract: Vinyl acetate is prepared from ethylene and oxygen by reacting ethylene, oxygen and acetic acid, formed during the process, at 50-300 C. and at normal or elevated pressures in the presence of a catalyst containing an elementary noble metal. The reaction product is separated into a gas and liquid phase consisting of vinyl acetate, acetic acid and water. The condensed components are heated in the liquid phase to 100-300 C., the acetaldehyde formed is oxidised to acetic acid which is used for the reaction with ethylene and oxygen to form vinyl acetate.

Title: Labyrinth seal for a hydraulic rotary machine
IPC: F04D29/16
Filed: 1968-07-03
Abstract: In an hydraulic rotary machine comprising a runner 1 which is sealed by a labyrinth seal and rotates sometimes in water and sometimes in air, e.g. a Francis turbine, a centrifugal pump or a reversible pump turbine, the parts forming the sealing gap are relatively movable whereby the gap is variable from a comparatively small amount when the runner is operating in water to an increased amount when the runner is operating in air. The runner 1 is sealed to the housing parts 4, 5 and 6, 7 by labyrinth seals 2 and 3 respectively and the non-rotating parts 10, 11 of the seals are connected by members 12 to servomotors 13 connected by ducts 21 and 22 to a fluid-pressure source. The position shown in Fig. 1 is intended for normal operation with the runner 1 rotating in water, the sealing gaps 8, 9 then being at a minimum limited by conical surfaces 23 o', the parts 10 and 11 pressed against conical surfaces 24 on the housing parts 4 and 6 by water pressure in annular chambers 25 communicating via ducts 26 with the water pressure space 27 of the machine. For operation of the runner in air, the parts 10 and 11 are moved outwardly by the servomotors 13 to increase the sealing gap 8, 9 by one step width as in Fig. 2 (not shown). During sliding movement of the parts 10 and 11, pressure water is supplied to the sealing gaps to act as coolant through ducts 28 leading from chambers 29 supplied from an external water source.

Title: Photochromic device based upon photon absorption
IPC: H04N7/00
Filed: 1968-12-05
Abstract: A display device comprises a photochromic screen 16, means 15 for selectively concentrating or focusing light at discrete regions within the screen volume to produce in these regions a power intensity to change the light absorbtion characteristic of the regions and means for directing on to the screen light of an intensity which produces no change to provide a three dimensional display. A light beam 12 from a laser 11 is passed through a light intensity modulator 13 and light deflector 14 which produces a two dimensional raster. The beam is then focused by a lens 15 on a transparent p.c. target 16 to provide a 10 micron diameter sphere of light of an intensity which turns the target opaque by double photon absorbtion. The target is moved to form the 3 dimensional pattern which may comprise a series of two dimensional patterns. Data is read by scanning the target with an unfocused beam or flooding the target with light from the laser 11 or another source. The pattern is erased by flooding or scanning the target. The p.c. material may be organic, CaF 2 La or SrTiO 3 : Fe, Mo, the source 11 includes ruby, A, Kr, Xe or Nd doped YAG lasers. The beam may be deflected by mechanical, electromechanical, electroacoustic or electro-optical means. Alternatively the laser or target may be moved.

Patent ES-425595-A1 (ES)
Title: Refrigeration system incorporating temperature responsive wax element valve controlling evaporator outlet temperature
IPC: F16K31/68
Filed: 1974-04-23
Abstract: The compressor provides hot refrigerant gas to the condenser and flow from the condenser to the evaporator is regulated by the thermostatic expansion valve, the sensing point of which is located in the return line betweeen the evaporator outlet and the wax element actuated suction line valve. A wax element actuated suction line valve is incorporated in the refrigeration system to respond to evaporator outlet temperature and thereby maintain evaporator temperature above a value which would permit frost accumulation on the evaporator. Since the evaporator temperature is controlled, the evaporator pressure is, to some lesser extent, controlled since the two are related. The wax element motor has an inherent temperature lag due to the thermal inertia of the wax and this tends to smooth out or stabilize the system and thus prevent or minimize hunting. The valve remains open as long as the temperature is above the set temperature regardless how low the pressure falls. This, then, enhances fast pulldown of the system. The wax element must be located completely upstream of the valve so as to be unaffected by refrigerant expansion as the valve throttles flow. Thus the wax element is located totally within the temperature to be sensed. In the principal embodiment the valve member is carried directly by the wax element housing and cooperates with the seat which also supports the spider or yoke supporting and guiding the wax element. Another variation incorporates a bellows assembly which functions to seal the wax element from the refrigerant and thus prevent any adverse effect on the elastomers normally incorporated in the wax element motor. In some cases there is no elastomer incorporated in the design with the bellows functioning to contain the wax medium while permitting flexure and, hence, operation of the valve.

Title: Support structure for a disc brake caliper
IPC: F16D55/2265
Filed: 1975-08-29
Abstract: A sliding caliper disc brake has a caliper member which applies friction elements to opposite sides of a rotatable disc and which is slidably mounted on a fixed torque-taking member by a single pin disposed at one side of the caliper. The other side of the caliper is urged into sliding engagement with the torque member by a spring arranged between the caliper and a projection on the torque member.
