Patent GB-923378-A (GB)
Title: Improvements in and relating to paper feed control for accounting and the like machines
IPC: B41J11/42
Filed: 1959-12-31
Abstract: 923,378. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 31, 1959 [Dec. 31, 1958], No. 44443/59. Drawings to Specification. Class 100 (4). The skip and line spacing paper feeds are controlled in a printer, tabulator, accounting, and like machines by programme means operating through electronically operated control circuits. The circuits include two counters the first of which counts the lines passing a print line and the second of which counts the lines to be skipped. On the receipt of a skip signal the second counter is advanced the number of lines to be fed and at the same time the paper feed clutch is engaged although due to delay in operation feeding does not occur until the counter is set. As the paper is fed lines passing the printing position send a signal to count down the second counter to zero at which point a derivedsignal stops the feed. As the second counter approaches zero it sends a signal to reduce the feed speed. If a line spacing or multiple line spacing signal is received test selection means select other circuits provided and allow the appropriate number of spacing step movements to occur.

Filed: 1975-06-23
Abstract: 1489363 Data transmission; signalling by DC PLESSEY CO Ltd 23 June 1975 [22 Oct 1974] 45633/74 Heading H4P A pulse signal sampling circuit for a succession of pulses in a determined slot of a repetitive cycle where each pulse may have distorted leading and trailing edges with a central undistorted part, has sampling instants varied in time relative to the theoretical centre of the undistorted portion of the signal pulses; relevant portions of these pass through a gate which is opened at the sampling instants. Variation of the sampling instants about the centre may be in cyclic manner, and the time interval between successive instants may be greatest at the centre and decreasing towards extremities. Separate arrangements are described in the Specification to produce such cyclic variation. In Fig. 3 (not shown) a modulation frequency is applied to a terminal (M) connected to the junction of opposed varactor diodes (15, 16) connected across a capacitor loaded transformer primary winding (11), the secondary (12) being connected to the enabling terminal of a gate (G, not shown). In Fig. 4 (not shown) a variable delay (21) co-operates with a monostable device (22) the delay being regulated by a modulation potential applied to terminal (M). In a third arrangement (Fig. 5, not shown) a phase locked loop has its operating frequency varied by the modulating potential (M) applied to the input or output of a filter (32). In the embodiments described eight sampling pulses comprise one cycle of time modulation. The modulator cycle time should not cause interference with the repetition frequency of signal pulses.

Abstract: 1279902 Printer or punch controller SIEMENS AG 25 Sept 1970 [26 Sept 1969] 45757/70 Heading G4H Device controlling a mechanical printer or punch for data carriers has a step-by-step and a fast speed feeding device. Data bytes from a processor DUA are converted at CU to 12 bit parallel code to be stored in a register REG. For each byte stored in the register a counter B2 is incremented. The bytes are e.g. to be punched on 80 column cards by setting up device EST enabled by clock pulses MT occurring one per column, the clock pulses also being fed to counter 52. When counters SZ, BZ are equal each byte is punched into its corresponding column and a circuit DU requests the next byte from the processor. If a series of zeros occurs which-do not involve punching operations they are detected by circuit LZE which causes circuit DU to request the next byte independently of clock pulses MT. Thus counter BZ can be incremented at a higher speed if a series of zeros are obtained. When counter B1 overflows a flipflop US is set to cause the printer or punch high speed feed to be operated. If the zeros are followed by a byte to be printed or punched this operation cannot occur until counters BZ and SZ are equal so that the byte is entered into its corresponding column.

Abstract: 1,208,359. Separable hinge joints; latch fastenings. BALDA WERKE PHOTOGRAPHISCHE GERATE UND KUINSTSTOFF R. GRUTER K.G. 27 Sept., 1968 [9 Oct., 1967], No. 45921/68. Headings E2A and E2F. [(Also in Divisions G2 and G3] A camera has a protective cover 7 for the lens and other operating elements, which cover has rigidly connected bearing pins 10, 11. The cover is attached by inserting these pins in a direction transverse to their axis into a hinge bearing on the camera body, where they latch automatically to form a detachable and releasable hinge. The bearing enclosures for the pins are formed partly by two mutually displaceable release slides 14, 15, partly by the walls within which the slides move, and partly by the ends 19, 20 of a leaf spring 21. When, in the "cover attached" position, slides 14, 15 are displaced towards each other by finger pressure, against the action of springs 24, the pins 10, 11 are uncovered, and free to move out of engagement with the bearing. They are urged out, or ejected, by the ends 19, 20 of the leaf spring 21, while at the same time locking noses 30, 31 of the spring latch behind the slides 14, 15 to retain them in the displaced position. The cover 7 thus separates from the camera body. To attach it again, it is pushed against the camera body so that the pins 10, 11 re-enter the bearing enclosure, and engage and press down the ends 19, 20 of the leaf spring These, and hence the locking noses 30, 31, are disengaged from the slides 14, 15, which are then free to return to their original positions under the action of springs 24. In so doing, they complete the bearing enclosures, in which the pins 10, 11 are retained, so that the cover is hingedly attached once more to the camera body. The cover can, while so attached, hinge down into the position shown in broken lines in Fig. 9, if required. The cover is latched closed (Fig. 9) by a locking lug 5 whose rim 4 engages in a groove 3 in the casing, and is opened by pressing downwards on an extension 8 of lug 5 (Fig. 8, not shown).

Abstract: 1371037 Film units EASTMAN KODAK CO 4 Oct 1971 [2 Oct 1970(2)] 46153/71 Heading G2X A photographic self-processing film unit assemblage comprises a plurality of film units, each of a predetermined length, a web connecting adjacent pairs of units, the disposition being such that the distance between the trailing end of a unit and the leading end of the next following unit is less than the said predetermined length. Fig. 3 shows an assemblage of three units 3, 5, 7, mounted on a transport web generally designated 9, said web comprising three leaders 11, 13, 15  connected in overlapping relationship. Unit 5, which is typical of the others, and is shown in exploded view in Fig. 7, comprises a first sheet 17 which has both the photo-sensitive layer and the image-recording layer, and a second sheet 19 registering with the first sheet. Sheet 19 controls the spread of the processing fluid, and is separated from sheet 17 by spacing members 21, 23. The fluid is contained in a double pod 25 which is ruptured on being pulled between two pressureapplying members 85, 77 in the camera 80, the fluid then being guided to enter between sheets 17, 19 by a funnel 27 made up of two sheets 29, 31. A trap 33 for excess fluid is provided at the farther end of the unit. As seen in Fig. 3, unit 5 has a leading end 41 and a trailing end 43, the overall length of the unit being L. Similarly leader 13 has a leading end 45, and a trailing end 47 which coincides with end 43, the overall length of the leader being 2L+S, so that the trailing end of unit 3 is a distance S from the leading end of unit 5. The distance S is made small compared with L, which is economical both as regards web material and as regards the amount of movement required. The short length S of the web allows the successive units to be folded into a superposed relationship, as shown in Fig. 8, which shows eight units so arranged, the top three being the three units 3, 5, 7 shown in Fig. 3. The leading portion 49 of the web 9, which is attached to a winding spool 57, is opaque and extends round the stack of units and over the top one to act as a protective dark cover. The cartridge Fig. 8 is inserted into the camera Fig. 12, and the spool 57 is wound on by a co-operating member 87, so that the previously exposed unit is pulled between the pressure-applying members 85, 77 to rupture the first pod 24 and spread the processing fluid. As the sheets 17, 19 are relatively stiff compared with the web, these continue substantially in a straight line to pass out of the camera through openings 73, 101, while the web 9, carrying the empty pod and the funnel, is stripped away from the remainder of the unit and would on to spool 57.

A switching matrix comprises strips of semiconductor material, each strip having 4-layer diode sections 60, 62 formed therein along its length to provide the columns of the matrix: corresponding diode sections of each strip being aligned and electrically joined to provide the rows. The initial block of semi-conductor material 58, say N-type, is oxidized on the surface and then etched away in a number of squares to allow P-type impurities to diffuse in and form the P-layer 52. In a similar manner further layers 54, 55 are created to form the NPNP diode. The block is then split into the strips containing a single column of diodes, the strips may be spaced apart or be merely separated by a charge carrier barrier section. The corresponding diodes are joined at the upper layer 55 or 57. The matrix is described in use in a telephone exchange where two matrices are cascaded, one NPNP diodes the other PNPN diodes. The diodes in the first matrix are fired at breakdown potential by a slowly rising edge; the subsequent charge of a capacitor coupled to the column then fires one of the diodes in the cascaded matrix by the created steeply rising edge.

Abstract: 1331761 Semi-conductor devices WESTINGHOUSE ELECTRIC CORP 30 Sept 1970 [30 Sept 1969] 46424/70 Addition to 1206859 Heading H1K The epitaxially deposited base region 14 of a high power transistor has a thickness up to 11 Á, allowing an active base width of up to 8 Á, and a resistivity of 0À3-2# cm. and is formed on a relatively highly resistive homogeneously doped zone 12 of the collector region adjacent a further zone 10 thereof whose resistivity does not exceed 0À1# cm. The zone 12 may be epitaxially deposited on the zone 10, or vice versa, or the zone 10 may be diffused into the zone 12. Whichever of these alternatives is employed, at least one high temperature treatment (such as epitaxial deposition or diffusion) is preceded by the step of clearing the exposed surface of the semi-conductor body to be heated with a chelating agent which removes deleterious trace amounts of metal surface contaminants. The preferred chelating agent is an ammoniacal solution of ethylene diamine tetraacetic acid. Without this chelating step it is not possible to obtain usable transistors of the above type having such large base widths. The base region 14 preferably has formed thereon, either by epitaxy or diffusion, a more highly conductive layer 18 of the same conductivity type. The emitter region 20 may be, as shown, diffused through the layer 18 into the base region 14, but other configurations using an epitaxial emitter region are also disclosed. A groove 28 surrounds the emitter region. Preferred materials for the semi-conductor regions and electrodes and preferred dimensions and resistivities &c. are specified.
