Title: Tractor
IPC: B62D11/18
Filed: 1980-07-24
Abstract: A tractor has a hydrostatic steering assembly 16 including a steering column 22 connected to a steering valve 18 mounted on a housing 10 for a dash. To dampen vibrations of the steering column 22, and to prevent any excessive movement of it when a high load is applied, a support assembly 26 is provided. This comprises a support column 28 with a bracket 30, at its upper end, which has an aperture 42 through which the steering column 22 passes. On the underside of the bracket 30, there is a polyurethane vibration dampening insert 32 which has an aperture 46 through which the steering column 22 also passes. The latter aperture 46 fits around the steering column 22 closely while the bracket aperture 42 is larger. Due to the difference in the sizes of the apertures 46, 42, slight deflections of the steering column 22 will be opposed only by the insert 32, but if a high load produces a large enough deflection, the insert 32 will be so compressed that the steering column 22 will come into abutment with the bracket 30 to limit its movement.

Title: Process and apparatus for the electromagnetic casting of metals and non-magnetic screen for use therein.
IPC: B22D11/01
Filed: 1980-10-08
Abstract: An electromagnetic casting process and apparatus is described and claimed for electromagnetically casting ingots having at least one corner or region of small curvature, e.g. rectangular ingots, in which means are provided which locally reduce the magnitude of the electromagnetic force field used to shape the ingot in the region of the corners so that metal flow into the corners is promoted. The localised reduction of electromagnetic force field is obtained either by using a non-magnetic screen (32) which provides increased screening in the corner regions of the ingot or by shaping the inductor (11) to provide a greater air gap between the inductor and the ingot in those corner regions. Optionally cooling fluid is applied asymmetrically to the ingot surface so that the solid-liquid interface (25) is locally lowered in the corner regions. Non-magnetic screens which provide increased screening and localised reduction of the force field in the corner regions of the ingot are also claimed.
Patent ES-8200805-A1 (ES)
Title: Amplitude modulator circuit for modulating a video signal on a carrier signal
IPC: H04N9/65
Filed: 1980-12-18
Abstract: Amplitude modulator circuit for modulating a video signal on a carrier signal. A first control loop which is coupled to the output terminal of the modulator comprises a first sampling circuit which is active during reference signal portions for generating a direct current compensation signal which is added to the video signal. As a result thereof the signal at the modulation input terminal of the modulator obtains a value for which, during the sampling interval, the signal at the output terminals is substantially independent of the signal at the carrier input terminal. A second control loop which comprises a second sampling circuit which is active during reference signal portions, generates a second direct current compensation signal which is added to the signal at the output terminal. This eliminates an effect of a variation in the direct voltage level at the output terminal, while the circuit automatically eliminates substantially the effect of an unbalance in the modulator.

IPC: F41A9/20
Filed: 1981-05-27
Abstract: One type of shipboard weapon system includes a vertical launch system for a number of guided missiles each of which is positioned in a housing in an array of missile housings. The missiles may be stowed in missile cannisters within each housing and the housings are sunk into the ship's deck so that the tops of the housings extend only a short distance above the deck surface. A service mechanism is provided for loading and unloading the missile cannisters from the housings and for transporting the missile cannisters between the housings and a set of missile supporting chocks located at the edge of the array of housings. The service mechanism has a base assembly which rides on a set of parallel tracks spanning the housing array. A carriage assembly is mounted for movement along the base assembly in a direction normal to the tracks. A portion of the carriage assembly is disposed for 360 DEG rotation about a vertical axis. A cradle elevator is mounted for movement on vertically running tracks on the rotatable portion of the carriage assembly. A cradle is adapted to engage and hold a missile cannister and is rotatably mounted on the cradle elevator to dispose the missile cannister with its long axis in either a vertical or a horizontal position. The cradle includes a hoist pawl which is adapted to engage one end of the missile cannister to raise or lower the cannister in the cradle when the long axis is disposed vertically. The base assembly is hinged intermediate its ends so that when the vertical launching system is not being serviced the carriage assembly may be positioned adjacent to one end of the base assembly and the other end of the base assembly may be folded upwards to lie alongside the carriage assembly. With the cradle elevator lowered and the cradle disposed in a vertical condition the portion of the base assembly underlying the carriage assembly is secured to an elevator which reaches up to the deck level. The elevator may thereafter be lowered to bring the service mechanism in a stowed configuration within the volume defined by three of the missile housings.

Patent ES-8300159-A1 (ES)
Title: Air-directing device for multiple cylinder dryer of paper machine
IPC: D21F1/00
Filed: 1981-11-30
Abstract: An air-directing device for directing air to the multiple cylinder dryer of a paper machine includes members for blowing dry air into the vicinity of the web at those points where the evaporation of water from the web is strongest. This reduces the humidity in such regions and promotes the evaporation of water from the web. The points are the initial parts of the cylinder intervals after contact with the web. The air-directing device is so placed, and its air-blowing members are so disposed and directed, that the air blown out from such members is directed into the clefts defined by the surface of the drying cylinder and the paper web. This achieves a pressure effect in the clefts. The air-blowing members are primarily used in connection with single fabric conduction in pockets on the side of the web to urge the web fast to the fabric and are preferably disposed on a doctor beam or in conjunction therewith.
Patent ES-8300579-A1 (ES)
Title: Single use ribbon cartridge with frangible resistive element for restraining the translating take-up spool.
IPC: B41J32/00
Filed: 1981-12-07
Abstract: In ribbon cartridges which are utilized in cooperation with a spacially fixed driving member engageable with a takeup spool at its periphery to feed the ribbon, it is necessary for the takeup spool to translate away from the spacially fixed driving member as the spool accumulates ribbon and the consumed ribbon forms disks of increasing diameter. A frangible portion of the cartridge may be utilized in conjunction with its transverse engagement with an extending axle coaxial with the takeup spool to resist the movement of the takeup spool into the chamber of the cartridge except as is forced by the increasing diameter of the ribbon disk formed on the takeup spool. The frangible section of the cartridge may be formed either during molding operation or as an additional member being added during assembly and will break or tear as the axle of the takeup spool is forced away from the end of the cartridge by the increasing diameter of the ribbon disk and the force of a driving member engaging the ribbon periphery. The frangible web section of the cartridge is sufficiently weakened to prevent structural damage to the ribbon mechanism while at the same time providing sufficient resistance to insure engagement of the exterior of the ribbon disk with the driver.

Title: Multichannel spectrophotometer.
IPC: G01J3/10
Filed: 1982-07-19
Abstract: A multichannel spectrophotometer has a single radiant energy source formed into a multiplicity of radiant energy beams which are each simultaneously intercepted by segments of a rotary source filter wheel, the spectral radiant energy output selected by each filter segment being directed into a separate source radiant energy conduit and transmitted to a remote sample station where a cuvette containing a sample to be analyzed is located, the radiant energy outputs of each cuvette being directed into a separate detector radiant energy conduit where each conduit is intercepted by a filter segment of a second rotating detector filter wheel identical to the source filter wheel and rotated in aligned synchronism therewith, the spectral radiant energy outputs of each segment of the detector filter wheel being further directed into a separate radiant energy detector and signal processing electronics associated with that sample station or spectrophotometer channel from which the radiant energy signal being detected and analyzed has been received. Central control, timing and display electronics are shared by each channel and may be overall programmed and controlled by computer. In one application involving the measurement of fluorescence, the filters of the detector filter wheel will be different from the filters of the source filter wheel so as to excite the sample cuvette at one wavelength and to measure fluorescent response at another.
