Title: Electronic computer with peripheral printing unit
IPC: G06F13/26
Filed: 1970-11-25
Abstract: 1334679 Printing ING C OLIVETTI & C SpA 25 Nov 1970 [25 Nov 1969 25 Sept 1970] 56150/70 Heading G4H In a combination of an electronic computer with a peripheral printing unit which unit includes a plurality of cyclically-movable printing elements, each adapted to print one of a set of characters on a recording support during each cycle, the computer includes code converting means for producing successive words for controlling the operation of the printing elements, each bit of a word corresponding to one of the printing elements. As disclosed, 8 type wheels, each bearing a full font, are spaced along the print line and rotate continuously about an axis perpendicular to the print line, being carried on a carrier reciprocating along the print line, so that during forward movement of the carrier, each type wheel can print a character in 16 consecutive positions on the line in respective revolutions of the type wheel, to give a line of 128 print positions, a second line being printed during reverse movement of the carrier. Each revolution of the type wheels, the printing unit causes a microinterruption of the computer (which is microprogramme-controlled) to cause the 8 characters required to be printed on the next revolution of the 8 type wheels to be read from the computer core memory, each character being used to address the microprogramme read-only memory to produce a microprogramme which inserts a bit in a set of 48 words, each of 8 bits, in the core memory to indicate the character, one word corresponding to each character in the font and the 8 bits of the word corresponding to respective type wheels. As each character comes into printing position during rotation of the type wheels, a microinterruption causes the appropriate one of the 48 words to be read from the core store and supplied via an 8-bit register in the printing unit to hammer drivers, one per type wheel, each driver receiving a respective bit of the word.

Abstract: 1419396 Making corrosion resistant components OMF CALIFORNIA Inc 6 Dec 1972 [16 Dec 1971] 56217/72 Heading B3A [Also in Division E1] A method of making a corrosion resistant component comprises depositing a noble metal layer on a metal substrate, diffusing the noble metal into the surface of the substrate by a heat-treatment operation and coating the heattreated substrate with a layer of corrosionresistant material. An alloy of Cu-Al-Ni-Fe forming a substrate is hardened thermally to 350-600 VPN and coated electrolytically with a gold bonding layer. The coated substrate is placed in a tube through which is passed pure hydrogen or an 80% N 2 -20% H 2  mixture, The tube is flushed with the gas and then placed in an oven at 400‹ C. and left for 25-45 minutes after the substrate has reached its maximum temperature. The tube is removed progressively so that the substrate temperature falls to 100‹ C. in about 10 minutes, the tube being then removed and allowed to cool. The heat-treated substrate is finally coated with Ru in a commercial electrolytic bath. The noble metal layer is preferably Au or Au alloy, but may be Pt or Pd. The corrosion resistant material is preferably Rh or Ru but may be Cr or a precious metal selected from the platinum group or their alloys. Alternatively it may be enamel.

Title: Photo-electric automatic positioning device
IPC: G05D3/14
Filed: 1971-12-03
Abstract: 1378759 Photo-electric position-finding NIPPON KOGAKU KK 3 Dec 1971 [4 Dec 1970 (2)] 56306/71 Heading H4D  An automatic positioning device comprises a light source 1 illuminating a rotating disc 6, the disc modulating the light to indicate the position of the image of slit 2 and hence the position of lens 4. The disc comprises a pattern of opaque and transparent portions and may take several different forms, the basic idea being to provide at least a signal indicating the image position along the Y axis and preferably two signals of different frequency to indicate the image position along the X or Y axes. The optical signals are converted to electrical form by cell 7 and compared in phase with corresponding reference signals provided by light sources 9, 10 and cells 12, 11. The X, Y servo-motors are then moved until the phase differences reach predetermined valves and the lens 4 is positioned correctly. To indicate the X position only, although not in accordance with the invention a disc having rectangular transparent and opaque portions (Fig. 5, not shown) would be sufficient together with reference signal portions Es. Movement of the image in either direction along the X axis carries phase shift of the optical signal (Figs. 4(D), (E), not shown) with respect to reference signal Eg (Fig. 4(c)). An alternative pattern (Fig. 6, not shown) could be provided. To indicate the Y position in accordance with the invention the pattern of Fig. 10 (not shown) can be provided, movement of the image in the Y direction producing the A.C. signals of Fgs. 9(E), (F) and (G) (not shown) for the positions S, S<SP>1</SP> S<SP>11</SP> of Fig. 9(A). These signals are compared in phase with the signal of Fig. 9(H) provided from portion Es<SP>1</SP> of the disc of Fig. 10. To give X, Y information the patterns are combined in disc 6 to give the disc of Fig. 11. An alternative pattern (Fig. 13, not shown) may be provided. Instead of a disc giving the Y axis position an endless tape may be provided (Fig. 8, not shown). In an alternative embodiment, (Fig. 22, not shown), the position of a member (103) having a slit (102) is determined, the member being for example an integrated circuit wafer. Light sources 9, 10 are replaced by a lens (113) and mirror assembly (114). The disc pattern is illustrated in Fig. 18 (not shown). Fig. 17 (not shown) illustrates the signals obtained for positions a, b, c, d of the slit image. Alternative patterns (Figs. 19, 20, 21) may be provided.

Title: Rocket Launcher Device
IPC: F41A19/29
Filed: 1966-12-21
Abstract: 1,174,049. Rocket launchers. OERLIKONBUHRLE HOLDING A.G. 21 Dec., 1966 [23 Dec., 1965], No. 57258/66. Heading F3C. A rocket launcher device comprises a launcher tube 2 having a rocket 8 held therein by a launching release mechanism fitted to the forward end of the tube 2 and a rocket motor ignition device fitted to the rearward end of the tube 2. The ignition device comprises a spring loaded, striker pin 16 guided within, and lockable to a sleeve 5 which in turn is guided within a locking component 9. The locking component is slidably guided axially in an end portion of the launcher tube 2. A spring 11 urges the locking component 9 towards the rocket 8 but the locking component is held against this spring pressure by means of the launching release mechanism which may include a cap 31 resiliently held in the mouth of the launcher tube 2 by a plurality of leaf springs 33, and a plurality of safety balls 30 urged into a groove 32 by the cap 31. The striker pin 16 is held in its cocked position by the sleeve 15 wherein the locking is effected by a plurality of balls 19 seated in holes 18 in the sleeve 15 and urged into a recess 17 in the striker pin by the walls of a bore in the locking component 9. The sleeve 15 is held against movement with respect to the launcher tube 2 by an arming spacer fork 21. On release of the launching release mechanism by pulling a ring 56 having a lanyard 34 connected thereto, the locking component 9 urges the rocket 8 forwardly, movement of the locking component releasing the balls 19 and allowing the preloaded striker pin 16 to be thrown against a primer charge 10. If the arming spacer fork 21 is not placed about the sleeve 15, the enlarged head 20 of the sleeve 15, on release of the launching release mechanism, enters the bore, in which the locking component 9 slides so that the sleeve 15 and striker pin 16 combination follow the motion of the locking component 9 such that the striker pin 16 does not engage the primer charge 10. In a modification (Figs. 3, 4, not shown) the rocket is held in the launching tube by a ball passing through an aperture in the wall of the tube and held therein by a rotatable sleeve, rotation of the sleeve freeing the ball. Also a further spring loading is applied the rocket.

Abstract: 1288056 Semi-conductor devices; image pick-up tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 Nov 1969 [27 Nov 1968] 57343/69 Headings H1D and H1K The identical radiation-sensitive elements of a mosaic formed in a semi-conductor body are mutually isolated by the provision of a doping profile in part of the substrate around each active junction or barrier such that minority carriers formed by incident radiation are swept only to the respective junction or barrier. An individual detecting element may be in the form of a junction photo-diode, a junction phototransistor, a PNPN device, or a Schottky barrier diode. The embodiments described are junction photo-diodes or photo-transistors and are provided as vidicon targets but variants may have an electrode array for use in scanning. Positive ion beams may replace electron beams in scanned vacuum tubes. Fig. 9 shows a phototransistor target with the base-collector junctions 6 acting as detectors; in a photo-diode variant (Fig. 1, not shown) the emitter zones 15 are omitted. The lightly doped N-type zones 4 are formed by epitaxial deposition in pockets in a highly doped N-type substrate 3. (The heavy doping is sufficient to prevent inversion under the oxide coating 12). The structure may be given a gradual doping gradient in the deposited zones 4 by allowing diffusion from the substrate 3 during or subsequent to the epitaxial growth. If the image and the scanning beam are both to be projected on to the upper surface a uniform electrode is applied to the lower surface, but if image projection is to be on to the substrate the substrate is thinned and provided with an annular electrode. A somewhat similar device is made as shown in Fig. 10. Here the P-type zones 16, 17 extend above the level of the initial substrate 3. In this case impurities for the substrates are diffused into the epitaxial layer 4 to give a doping gradient for a drift field and the substrate and that part of the epitaxial layer below line 21 (which separates a doping level of 10<SP>17</SP> atoms cm.<SP>-1</SP>) are removed by a selective electrolytic etching step to leave a body in which the N-type region does not extend in thickness further than a diffusion length from the junction so that nearly all absorbed radiation is effective. In a further manufacture (Figs. 12 and 13, not shown) a photodiode array is produced from a uniformly doped N-type starting wafer by providing an apertured oxide mask and out-diffusing phosphorus through the apertures to leave graded regions in which P-type regions are then formed by indiffusion. Process details are given for all embodiments. The devices described are of silicon but germanium and A<SP>III</SP>B<SP>V</SP> semi-conductors may be used and heterojunctions may be employed.
