Abstract: An optical matrix-vector multiplier for multiplying an m-row n-column matrix by an n-component vector to form an m-component vector (Figure 1). In the specific case of a 3 * 3 matrix (Figures 4a and 4b), the multiplier comprises three light-emitting devices (21, 22, 23), for example LEDs, each emitting at a different wavelength ( λ 1 , λ 2 , λ 3  ), an acousto-optic modulator (29) driven by each x value in turn, and three integrating photodetectors (32, 33, 34) each receptive to a respective one of the different wavelengths. A single collimating lens (30) serves to apply hght. emitted by each of the LEDs in turn in response to respective matrix components, to the modulator (291 The LEDs may be connected by respective optical fibres (24, 25, 26) to a fibre coupler (28) and thence via a common optical fibre (27) to the lens (30), or coupled by a dispersive element (35 - Figure 5) to the lens (30). Use of a single collimating lens facilitates integration of the multiplier elements into an integrated optic device.

Abstract: An improved railroad stub switch is described in which the axial rail tension or compression forces due to temperature fluctuations are transmitted through the switch by means of radius arms connected to both the switch and fixed rails, thereby eliminating the need for expensive expansion joints at the switch. In a preferred embodiment, interlocking point shoes are also employed so as to hold the butt ends in vertical and horizontal register and transmit a signal to the trailing side rail of the impending approach of a load from the approach side rail, thereby reducing batter on the trailing side rail.

Abstract: A leather, in particular a skiver, has depressions on at least one side and also absorbent, protruding fibres on that side. This side is bonded to a layer (14, 14a) which has been formed from an aqueous polymer dispersion and which fills out the depressions and completely absorbs the protruding fibres of the leather (13). This layer (14, 14a) forms either the entire surface finish or, in a two-layered structure thereof, the inner layer (14a) thereof. In this case, the inner layer (14a) has on top of it an outer layer (14b) which has been formed from an aqueous polymer dispersion or from a liquid polymer solution and which has been provided with a textured surface (16). 
<??>Such a surface finished leather is made by applying to the leather, to form the surface finish (14), an aqueous polymer dispersion in an amount between 150 g/m<2> and 450 g/m<2> in the wet phase, then placing the leather with the surface finished side facing down onto a base (2, 2') having a textured surface, and finally press bonding the leather to the applied polymer dispersion and subjecting it to a vacuum treatment. If the surface finish is to have a two-layer structure, then, before the leather with the aqueous polymer dispersion is placed on the textured surface of the base (2, 2'), the latter has applied to it a further aqueous polymer dispersion or liquid polymer solution, and the leather is placed on top of the base only after this further aqueous polymer dispersion or liquid polymer solution has solidified.

Title: Signal mixer for microwave radio systems
Inventor: SELVAZZO GIANFRANCO
IPC: H03D7/12
Filed: 1986-05-21
Abstract: A signal mixer for microwave radio systems is proposed, consisting mainly of a single gate field effect transistor (2) (SG FET) provided with a self-bias circuit (4 to 10) powered from a local oscillator (3) with which the mixer is connected. 
     The proposed active transistor mixer affords a high conversion gain with a low noise figure and a minimal amount of circuitry. 
     The gist of the solution consists in injecting the signal produced by the local oscillator (3) into the drain D of the SG FET transistor (2). 
     This will eliminate both the supply voltage at said drain and the related noise contribution. 
     At the same time the local oscillator (3) will also supply all the bias voltages needed for the operation of the transistor (2).

IPC: G11B19/02

Abstract: An optical storage system achieves high density, sufficiently high to permit both video and audio to be stored on a compact disc, or to store other data at very high density. Pits are encoded on the disc storage medium with respect to timed electronic reference signals (not simultaneously optically encoded on the disc) which divide each revolution of the disc into a multiplicity of equal spaces or references. The pits have leading edges on the leading side of a reference signal and trailing edges on a trailing side of the reference signal, so that each pit straddles a reference signal. The length of the pit leading up to the reference signal represents one sample of information, while the length of the pit from the reference signal to the pit's trailing edge represents another sample of information. In this manner high density is achieved at high accuracy and low noise, since one end of each bit of information is precisely located and readable without the lesser precision involved in determining the location of the leading and trailing edges of the pit in reading the information. On the disc the reference signal frequency is generated during the vertical retrace interval(s), encoded by equally spaced pits, for correlation with the prevailing speed of revolution of the disc. At each horizontal picture line (e.g., 525 per revolution) there is at least one reference pit. When this is detected the amount of phase shift which may exist at that line is measured and corrected for. Two samples of the video waveform are reproduced and measured for each pit. Small compact video discs can be produced with inner diameters of 2˝ to 4˝, or video bandwidths of up to 10 MHz can be produced for high resolution pictures.

Abstract: This invention relates to a multi-cavity valve gated injection molding system wherein a continuous flow of hydraulic fluid through the actuating mechanism provides additional cooling. A pair of hydraulic fluid lines (114, 118) are drilled in the mold back plate (12) to apply a minimum pressure differential across the cylinder chamber on one side of the piston (60). In the preferred embodiment, this pressure differential is also applied to opposite sides of a circular cooling chamber (110) extending through the cylinder (62) to provide additional cooling near a high pressure seal (70). Additional cooling is very advantageous to avoid system malfunctions and inferior product, particularly when molding high performance engineering resins at a high temperature.

Abstract: The present invention relates to an optical heterodyne mixer providing image-frequency rejection which (a) detects a desired signal at frequency ∫L.O. ± J IF while rejecting interference from any signal at the image frequency J L.O. ± ∫ IF, and (b) provides performance which is insensitive to fluctuations in the optical dimensions of the circuit. More particularly, the mixer receives both a local oscillator input signal and a received input signal comprising one or more optical signals, one of the input signals being linearly polarized and the other being circularly polarized. The two signals are merged by an optical device (30) and transmitted to a polarizing beam splitter (31) which has its polarization axes oriented at 45 degrees to the polarization direction of the linearly polarized signal. Each of the two beams from the polarizing beam splitter is detected by a separate photodetector (34,35) and the resulting two currents from the two photodetectors are added by means of a 3 dB 90 degree IF coupler (38). One of the coupler outputs (39) provides the IF signal and the other coupler output (40) provides the IF signal of the image frequency.
