Abstract: The present invention relates to a method and an apparatus for the manufacture of dental prostheses by means of an electroerosion process by using two template electrodes for erosive excavation. The dental prosthesis to be inserted is made directly from solid material which has not been previously worked. The negative templates of the dental prosthesis contained in the template electrodes can also be made by the electroerosion method. The manufacture of the dental prosthesis can be accomplished by a simultaneous movement of the two template electrodes or by manufacture of the two form halves of the dental prosthesis at different times.

Abstract: The present invention relates to a QPSK nodulator for modulating two different input bit streams with a subharmonic pump carrier signal to produce an appropriately encoded QPSK output sig- al. The subharmonic pump carrier signal used is a submultiple of a predetermined microwave or millimeter-wave carrier frequency. The QPSK modulator is capable of being fabricated on a planar substrate 24 using appropriate stripline filters 12,13,16,17,20,21 and a mixer diode 18,19 in each of an in-phase 11 and quadrature 11 signal path. A fin line arrangement, also capable of fabrication on the substrate, can be used to introduce an appro- oriately phased subharmonic pump carrier signal into each of the in-phase and quadrature signal oaths before each mixer diode. Each mixer diode mixes the associated data bit stream and one of the two appropriately phased pump carrier signals to produce separate output signals which modulate along separate orthogonal axes, which output signals are combined in combiner 22 to produce the QPSK modulator output signal.

Title: Sealing system for containers
Inventor: DE ANDREA LENCASTRE GODINHO LU
IPC: B65D45/32
Filed: 1986-12-02
Abstract: The present invention refers to a sealing system for plastic containers intended mainly to be used for food preserves, more precisely to a sealing system for canned goods. It is characterised essentially by a clamping strip (6) which applies tightening pressure on the existing fitting between the rim at the edge (2) of the container (1) and the groove (4) at the periphery of the lid (3). The necessary tightness to preserve the packed goods can be achieved this way. This new system also allows an easy and quick opening of the container, being sufficient, in order to do so, to tear-off the clamping strip (6) which is provided with any system suitable for the purpose.

Abstract: The invention refers to some improvements in the foldable frames for children's pushchairs, of the type which includes the handlebar fitted slidingly over the front legs, with the folding of the pushchair being obtained with the bringing down of the handlebar.

Abstract: A recording material is described which essentially consists of a substrate, a light-sensitive layer, applied thereon and containing a binder which is insoluble in water and soluble but at least swellable in aqueous alkali and in organic solvents and an o-quinonediazide, and a contrast enhancing layer which contains a diazonium salt which can be decolourised by light and a strongly acidic, water-soluble and film-forming polymer. The recording material is in principle positive-working but, after the addition of a crosslinking agent to the light-sensitive layer and subsequent crosslinking, may be negative-working. By using the strongly acidic polymers, the stability of the contrast enhancing layer is ensured. At the same time, this layer may be extremely thin, with the result that a substantial increase in the image-resolving power and in the development contrast is obtained in comparison with contrast enhancing layers which contain no polymeric acids.

Abstract: A load-lifting mast (10) especially adapted for an automatically-guided, driverless vehicle (20) has automatic features for ensuring accuracy and reliability of operation despite the absence of a driver. For load-­lowering purposes, a slack chain sensor (58) senses whether or not the load-supporting carriage (16) is supported by the mast (10), and the carriage (16) is withdravn from the load when no support by the mast (10) is indicated. The slack chain sensor (58) also cooperates with a carriage height control system (54, 56) by over­riding it to cause lowering past a target height until the carriage (16) is supported independently of the mast. A carriage height sensor self-calibration system continually recalibrates the height-sensor (54) readings automatically while the mast (10) is in use to compensate for height sensor slip, chain stretching, and other mechanical variables. The slack chain sensor (58) cooperates with the self-calibration system to enable it to reference to the ground or other surface upon which the vehicle (20) travels to compensate for such other variables as tire wear. The mast (10) is preferably powered by an electric motor-driven screw member (32) having a wear-preventing, universal-joint-type connection (40) to the carriage-­lifting mechanism (42) to prevent the imposition of unsymmetrical loading on the screw member. The electric motor (34) has field effect transistor controls operable over a wide range of source voltages.

Inventor: BRYANT STEWART F
IPC: G06F13/28
Filed: 1988-03-25
Abstract: Incoming data which is required to be passed to a desired storage location under the control of a processor is received by a store prior to being passed to a serial communications controller. The store is preferably a FIFO store and stores the data at an incoming data rate determined by the incoming transmission line data rate and feeds the data to the serial communications controller at a higher data rate under the control of a clock generator which is energised by control circuitry only when the data may be accepted by the serial communications controller. The processor can therefore control the serial communications controller to cease to process incoming data, which data is then stored until the processor can spare the time to recommence processing the incoming data.

Abstract: A method of selectively incrementing and decrementing the decimal values of digital filter tap coefficients is disclosed. Each tap coefficient is represented by a plurality of cannonic signed digit (CSD) encoded "nibbles". The combined CSD-encoded values of the individual nibbles bear no direct relationship to the decimal-valued tap coefficient, the range of each nibble is restricted to allow such a direction relationship. Each CSD-encoded value is adjusted by incrementing, decrementing or placement at an endpoint of its range and direction reversed, whereby the resulting decimal value will be incremented or decremented. The sign and direction of movement within the range of each nibble is readily ascertained by reference to a set of simple rules.
