Abstract: 1,065,128. Feeding webs. KIMBERLY-CLARK CORPORATION. Nov. 1, 1963, No. 43246/63. Heading B6B. An endless canvas belt 158 is passed round a motor-driven roller 12, a cradle roller 13 carried on arms 24 pivoted at 25, between pinch rollers 14, 15, and over guide rollers 16, 17, 18, 23 in such a way as to be kept loose between the rollers 12, 13 to form a pocket to receive a web wind-up core 157 which is rotated by the belt to wind up the web. Initially, the arms 24 are urged to the right against latches 55 by air in cylinders 54. In operation, the urging of the arms 24 to the right is placed under the control of a variable pressure pneumatic device controlled by a cam mounted on the lower end of one of the arms, the pressure increasing as the diameter of the web roll increases to force the arms to the left, to maintain constant tension. The latches 55 are pneumatically withdrawn by air in cylinders 58 and the motor 21 is started. The rollers 12, 13, 14 have a non-slip covering. The tension is adjustable by moving the roller 16 laterally along screws 37 by rotating a shaft 41. When the roller 14, which is driven from the roller 12 through an adjustable slip clutch, reaches a certain speed, a centrifugal governor associated with the motor shaft actuates a solenoid switch controlling a valve which causes movement of one end bearing of the roller 14 to separate the rollers 14, 15 to minimize wear on the canvas. Lateral movement of the belt actuates a paddle 51 controlling a fluid pressure motor 49 to move one end bearing of the roller 17 so as to correct the lateral position of the belt. When the web roll reaches the desired diameter, the motor 21 is stopped, the pressure in the cylinder 54 is reversed to move the arms 24 to the left, the web is cut off and the web roll is rolled out along the belt portion between the rollers 12 and 13. A pneumatic brake is actuated so as to ensure that a loop 10a exists between the rollers 12, 13 when the arms 24 are later returned to their initial position engaged by the latches 55. The roller 14 is driven at a slower speed than the roller 12 to keep the belt taut from the roller 15 round the rollers 16, 17, 18, 23 to the roller 12.

As shown, a porous combustible layer 30 such as deionized cellulose is sandwiched between non-combustible layers 32 and 34 such as of aluminium, copper, tantalum or brass foil to form a tape 10 and aligned apertures such as 36, 42 to provide sample storage sites such as 48. An annular ring of paraffin wax may form a barrier to limit transfer of materials added to the storage sites. Alternatively as in Fig. 2 (not shown) tape 10 consists of a non- combustible material (12) having regularly spaced apertures (14), (16) and disposed over each aperture are porous, combustible discs (20), (22) for the retention of a sample aliquot. The tape 10 is unwound from reel 80 Fig. 4 and indexed by drive means 82 after passing through a plurality of stations. An aliquoter 86 withdraws a measured portion of sample from one of the cavities shown in wheel 84 and transfers it to a storage site on tape 10. After passing through drying stations 90 the storage site passes directly over micro burner 92, and the spectral flame F is detected by photodetectors 94. The results can be computed and recorded on the sheet 96 by recorder 98. An internal fuel supply may be obtained from distilled water which is decomposed into hydrogen and oxygen and fed into the burner. A spectrometer Figs. 5 and 6 (not shown) may be utilised with the apparatus in which the light from the flame is diffusely reflected within the walls of a chamber coated with magnesium oxide and photo-detectors view this radiation, filters being provided as necessary.

Title: Ranging device

IPC: G01S17/14
Filed: 1968-09-13
Abstract: 1,237,134. Ladar. MARTIN-MARIETTA CORP. 13 Sept., 1968, No. 43689/68. Heading H4D. In laser pulse radars spurious echoes are often produced by objects between the radar and the target, the laser radar described thus provides for only passing to range measuring means the predetermined nth one of the echo pulses received. Normally said echo pulse is the last received. The range measuring means comprises a standard frequency generator and a pulse counter, wherein counting of the output of the generator starts with the transmitted pulse and is stopped by said passed pulse. The means to pass said nth pulse in input A, Fig. 4, comprises an AND gate 58, Fig. 3, fed with said input and enabled via OR gate 56 by that one of AND gates 46/52 having its lower input earthed by switch S, the upper inputs of the AND gates 46/52 being sequentially energized by the outputs of respective bi-stable devices 10/16, via inverter/amplifiers 18/24. Switch S set to n (4 in this example). Initially at time t 0 , Fig. 4, the bi-stable devices are reset giving negative output at their lower stages and high output from inverter/amplifiers 18, 20, 22 and 24. All the AND gates are enabled by a negative signal applied thereto. At time t 1  the first (interference) echo appears and passes to set bi-stable 10 via AND gate 34 which is enabled by the reduced output from amplifier 42 (waveform F). The output B of amplifier 18 thus goes negative, thus enabling gate 46 fractionally after the occurrence of said first echo. No output occurs from the gate however, since switch S is not positioned to earth its other input. The negative output B also enables gate 36 whereby the second echo signal at time t 2  passes therethrough to set bi-stable 12 (C 1 , Fig. 4). This causes the enabling of gates 38 and 48 at time t 2  +. The subsequent setting of bistable 14 at time t 3  by the third echo pulse via gate 38 causes the enabling of gates 40 and 50 at time t 3  +. Thus gate 50 produces an enabling output for gate 58 since signals are applied to both its inputs, whereby the desired fourth echo pulse passes through gate 58. The fourth pulse also causes, via the setting of bi-stable 16, the resetting of bi-stable 10. If it is desired to pass the first received echo pulse at t 1 , switch S is set to 1, whereby the ground potential via amplifier 54 provides the enabling signal for AND gate 58.

Abstract: 1280630 Modulating light STANDARD TELEPHONES & CABLES Ltd 16 Sept 1970 44180/70 Addition to 1280545 Heading H4F Various layers are provided on the surface of the semi-conductor body, in the scanning system described in the past parent Specification, to provide a surface which is distorted on passage of a high field domain through the body. Thus an oil film in direct contact with a piezo-electric semi-conductor body is distorted by local heating due to the high phonon density in the domain. A resistive layer may be interposed between the oil film and body to provide a local heating effect due to the potential across the domain. In another embodiment a grounded metal film overlies an insulating plastics membrane which is spaced from the body and is electrostatically deflected particularly on the high voltage side of the domain. Alternatively an oil film may replace the membrane, being spaced from the body by an insulating layer. A further arrangement comprises, in order, the body, a space, an insulating plastics membrane, a high resistance coating (graphite) connected to a potential source to charge the membrane, a further space and a transparent grounded electrode. The charged membrane distorts in the presence of the domain. Memory effects may be introduced e.g. by choosing an oil film of suitable viscosity and thermal resistance or reducing the rate of electrostatic discharge. By making the body sufficiently thin, it is possible to position the light source of the Schlieren system so as to transmit light through the body on to the inner surface of the layer, rather than the outer surface.

Element 10 is separated from copper films 20, 22 by electrically insulating layers 12, 14. Members 16 and 18 may be of Permalloy being separated at the back gap region by layer 12; alternatively such separation may be omitted if one of members 16, 18 is of insulating ferrite in which case a substrate 28, on which the assembly is formed by evaporation, may be of the same ferrite and formed with such ferrite member. During reading, current control circuit 26 supplies direct current of opposite direction but equal magnitude to films 20, 22 to provide a bias for element 10. During writing circuit 26 supplies current in the same direction to both of films 20, 22 and to record data these currents are pulsed to change directions simultaneously. A fringe field is thus established between members 16, 18 to effect recording, element 10 having little effect on this field, and no field being set up between member 16, 18 by the currents to films 20, 22 during reading. Element 10 may have a thickness of 200 to 500 angstroms and members 16, 18 may have a thickness of 2,000 to 50,000 angstroms and may be wider than element 10 to provide wider write tracks than read tracks. It is stated that the effective read gap length is half the write gap length. The head assembly may be used to record on a mediun having a low coercivity of 150 to 200 A/m. Multi-turn or multi-coil arrangements formed by conductive films may be incorporated in the head to allow use of lower write current or of higher coercivity recording media. The following abridgments are included in this series since the Specifications were through an error, not allotted to this group. References to them will be found in the name index to this volume.
