Title: Apparatus for the relative positioning of two plane parts
IPC: G02B21/00
Filed: 1968-11-29
Abstract: 1,254,438. Positioning device. LIGNES TELEGRAPHIQUES ET TELEPHONIQUES. Nov.29, 1968 [Dec.13, 1967], No.56690/68. Heading G2J. In photo-engraving or vacuum deposition in which a mask is to be accurately located with respect to a component, the mask P, Fig. 4, is first located relative to a test piece T by means of an optical alignment apparatus, the mask P is clamped in a frame having abutment surfaces against which the test piece T rests and the latter is replaced by a sample component engaging the abutment surfaces. The alignment apparatus comprises a two beam optical system incorporating an adjustable control 8, Fig. 1, to pre-set the distance 'd' between parallel beams to that between reference masks r, r<SP>1</SP> and circular aperture 1, I<SP>1</SP> on the mask P and test piece T. They can be aligned by moving one relative to the other till the correct patterns on the frosted glass screen E or 6, Fig.1, are obtained as shown. The images are magnified by lenses 1, 2 and brought closer together by prisms 3 and 4. The test piece T is first placed in holder 31 so that springs hold it against three abutments in the form of a right angle, the holder then being disposed on a disc 26. The mask P, not shown in Fig. 1, which has been cut out with the aid of a template so that the reference marks are roughly in the right area, has one end of its edges gripped between the jaws of a fixed clamp 18. The opposite end is held by a movable clamp 20, with a drawback spring 23 around a pin 22 attached to the clamp, providing tensioning of the mask. Then the positioning is effected by means of micrometer screws 27, 28, and 29 which can move outer annulus 25 and inner disc 26 in two orthogonal directions, and rotate the disc 26 relative to the annulus 25. When correct centering has been reached, the mask is fixed to the component holder 31 by placing a frame (46) Fig.3 (not shown) on top and tightening fixing nuts. Then clamps 18 and 20 are released and holder 31 is withdrawn from the apparatus.

The fingers are then lowered and the two sheets are fed onwards side by side by the belts 1 to two driers. This process is repeated so that alternate sheets are displaced laterally.
Patent GB-600622-A (GB)
Abstract: 600,622. Automatic phase-control systems. SOC. FRANCAISE RADIO-ELECTRIQUE. March 8, 1945, No. 5827. Convention date, Feb. 14, 1942. [Class 38 (iv)] [Also in Groups XXXIX and XL(c)] In an automatic phasecontrol system for maintaining the signals A and C1 received by two aerials in phase coincidence in a radio direction-finding system, (see Group XL(c)), one of the signals C1 is phase modulated with a phase excursion of # degrees by a low-frequency voltage and then combined with the other signal A to give a resultant signal the amplitude of which varies at the frequency of the modulating voltage and the degree of amplitude modulation being proportional to the phase error #. The resultant signal is demodulated and the low-frequency component is applied to a balanced demodulator together with the modulating voltage to give a D.C. error voltage of variable amplitude and reversible polarity which is applied to vary by electro-mechanical means the tuning of a circuit in the path of the phase-modulated signal ; the phase of this signal is thereby varied to bring it into coincidence with the other. Fig. 5 (not shown) illustrates the application of such a system to a radio direction-finder.

Abstract: 1372228 Data processing systems RCA CORPORATION 29 Dec 1971 [7 Jan 1971] 60355/71 Heading G4A Each of a number of computers sharing a common transmission channel has an associated control circuit, the control circuits are connected in series to receive and re-transmit a control signal from one to another, and each control circuit, when actuated by a channel access request from its associated computer, notifies that computer that it may have access to the channel on receiving the control signal and prevents re-transmission of the control signal to the next control circuit in the series. In a first embodiment, Fig. 1 (not shown), the control circuits are connected in a closed loop separate from the communications channel shared by the computers. In a second embodiment, Fig. 4 (not shown), data and control signals are sent serially by bit over a common channel. In this case the control signal is a special code which is recognized by a decoder in each control circuit to initiated seizure of the channel by the associated computer if it is requesting access. Each byte received by a control circuit is shifted serially into an input shift register and is transferred in parallel to an output shift register from which it may be transferred in parallel to the associated computer or shifted out serially to the next control circuit in the loop. A computer, when it has seized the channel, supplies bytes in parallel to the output shift register for serial transmission over the channel to a computer identified by the address code in the first byte transmitted.

Title: Optical scanner and system for laser beam exposure of photo surfaces
IPC: G03F1/00
Filed: 1978-06-12
Abstract: An optical scanner which introduces a 'horizontal' scan component into combined 'read' and 'write' beams from a laser while introducing no 'vertical' angular component. The beams are subsequently passed through a field flattening objective lens and then are separated for passage to a read platen and exposure or write platen respectively. The scanner has a scanning wheel in the form of triangular regular pyramid cut from a circular disc, its sides (faces) constituting planar reflector segments. The faces deflect the combined beams by one half of the pyramid's angle. Adjacent the scanning wheel is a roof reflector doublet mirror by which the beams are returned to the scanning wheel from which the beams are again reflected a second time. As each segment rotates through the beams' path its varying angular orientation introduces horizontal and vertical components of angular deviation into the beam, the horizontal angular component being doubled upon the second (output) reflection from the wheel segment while the vertical component is cancelled by inversion through the roof reflector doublet. <IMAGE>

Abstract: 783,215. Materials for a gasification or carbonization process. ESCHWEILER BERGWERKE-VEREIN. July 11, 1955 [July 9, 1954], No. 20040/55. Drawings to Specification. Class 55 (2). Washery slack produced in the preparation of coal and other mineral substances having a content of carbon, such as oil shale, are separated by known methods into a number of grades of different carbon content or different contents of volatile carbon and hydrocarbon compound constituents, and each grade with the exception of the grade which is poorest in carbon is separately subjected to gasification of carbonization controlled according to its carbon content or content of volatile carbon and hydrocarbon compound constituents. Washery slack is sorted into grades such that each grade contains approximately the same quantity of carbon. In an example the washery slack is divided into five grades : grade 1 having an average carbon content of 27.6 per cent, grade 2 19.7 per cent, grade 3 14.6 per cent and grade 4 8.1 per cent, the fifth grade or residue being discarded. Each grade to be gasified is gasified with hot air in a separate gas producer or carbonizing oven with a travelling grate, the richer grades being subjected to a longer gasification or carbonizing time. The poorer grades may have in admixture a fine grained grade which is richer in carbon, the distribution of the particles being evenly mixed so that the amount of carbon available per unit surface area to oxidation to carbon monoxide is the same throughout the charge. Carbonization may be followed by gasification of the carbonized material.
