Title: Roll hardness device
IPC: G01N3/00
Filed: 1970-11-02
Abstract: 1328158 Hardness measuring CONSOLIDATED PAPER (BAHAMAS) Ltd 2 Nov 1970 [5 Nov 1969] 51944/70 Headings G1S and G1N A hardness tester comprises a means for applying a force to a test piece thereby forming a contact area, a first means for obtaining a first value corresponding to such force, a second means for obtaining a second value corresponding to a force experienced by an area of the surface of the test piece which is less than the contact area, and means for comparing the two values. The hardness of a paper roll 20, Fig.1, is tested by pressing a rotatable wheel 58 against the roll, the wheel being journalled in a slidable frame 50 supported in a movable carriage 40 itself mounted on a pedestal 14 movable along tracks 16. The wheel supports roll contact buttons 60, 62, Fig.3,5, which successively contact relatively large and small areas of the roll which may not be completely round and compress piezo-electric crystals 61, 63. The pulses generated in the crystals pass through impedance converters 70, 72, Fig.6, within the wheel and are collected by slip rings 73, 75 and conducted to further circuitry comprising amplifiers 74, 76, and impedance matching circuits each comprising a capacitor, a resistor and a reverse biased diode. The output of the two integrating circuits is a D.C. voltage proportional to the heights of the input pulses, and in order to measure the ratio of these voltages, which gives a reasonable indication of the roll hardness, they are fed to an analogue divider module 78 through impedance matching circuits 80, 82 respectively. The output of 78 is a D.C. voltage proportional to the two inputs and forms a suitable signal for strip recording. The output indicates the hardness of the roll 20. The button 62 could be dispensed with by providing a constant loading means for holding the wheel 58 against the roll 20 and the hardness would then be obtained directly from the load sensed by the small button 62. The crystals may be replaced by strain gauges or other energy conversion devices, and the output from the apparatus may be used to control the roll winding.

Abstract: 1,214,156. Collimating marks. CARL ZEISS JENA VEB. Nov.20, 1967 No.52638/67 Heading G2J. [Also in Divisions G1 and H4] A collimating mark 1, Fig. 2, for observation through double-image telescopes is divided into a plurality of opaque sections 14, 15, and transparent sections 20, 21, 26-29, the sections being of triangular shape with their bounding lines 16-19 and 22-25 intersecting at a central point 10, at least two of the sections 14, 20, being congruent and opposite to one another with the prolongation of at least one bounding line 22 of one section 20 coinciding with a bounding line of the other section 14 and the total areas of the transparent and opaque sections respectively being substantially different. If the double image telescope axis is aligned with point 10 the image of section 20 combines with the reversed image of section 14 to produce a uniformly grey area but if the axis is misaligned in one coordinate direction a black and a white stripe, Fig. 4, (not shown) are produced whose widths correspond to twice the misalignment of the telescope axis. Similarly superposition of the image of section 21 and the reversed image of section 15 determine the misalignment in the other co-ordinate direction. In a modification the collimating mark can only be used for determining misalignment in one direction. As shown, Fig.7, double images of the mark 1 are produced by lenses 38, 39 and prism 40 in plane B1 and this is reproduced at plane B2 by lenses 41, 42, and a mirror 44 in the dotted line position for viewing by eye-piece 45. When mirror 44 is in its full line position the image at plane B1 is reproduced by lenses 41,43, at a plane B3 containing a diaphragm 46 in front of photo-electric receiver 47 having a plurality of differential photo-electric cells If the telescope axis O-O is misaligned with the centre 10 of mark 1 the output of receiver 47 is used rotate parallel plates 36, 37, about axes X 1 -X 1  and X 2 -X 2  respectively to realign the system.

As shown in Fig. 2, identical drying units 10, 10<SP>1</SP> are placed side-by-side and their respective fabrics 18, 18<SP>1</SP> are pre-shrunk by a single compressor 14. In each unit 10, Fig. 1, fabric 18 is fed from a truck 38 around rollers 40, 42, 44, 46, around drying cans 22, 24, 26, through an adjustable tension responsive control system 48, over rollers 50, 52, through a moisture applying unit 12 and into the compressor 12. The drying cans 22, 24, 26 are driven by a belt drive 28 in response to rotation of a pulley 32 actuated by a D.C. motor 34 through a speed reducing right angle gear box 36. The system 48 includes an endless belt. 54 carried by freely rotatable pulleys 56, 58, a pulley 60 rotatably carried by the belt 54 and an adjustable weight 62 carried by the belt 54. An endless chain 68 communicates rotation of a sprocket 66 secured to the pulley 58 to a sprocket 70 mechanically controlling a potentiometer 72 to produce variable signals to a control box 76 controlling the speed and direction of operation of the motor 34. In operation, any increased tension in the fabric 18 after it has passed over the cans 22, 24, 26 causes the pulley 60 to rise so that the belt 54 moves the sprocket 66 clockwise so that the control box 76 increases the speed of delivery of the fabric 18 over the drying cans. If there is too much slack in the fabric 18, the pulley 60 drops and the motor 34 is driven to take up the undesirable slack. The unit 12 comprises guide rollers 80, 82, water pipes 86 having spaced nozzles 88 therealong and steam pipes 92.

Title: Pulse amplitude modulated data receiver
IPC: H04L7/033
Filed: 1973-11-15
Abstract: 1444409 Receivers; active filters INTERNATIONAL BUSINESS MACHINES CORP 15 Nov 1973 [29 Dec 1972] 52962/73 Headings H3H and H3U In a receiver for pulse amplitude modulated signals, timing errors are corrected without the need for sampling operations at the receiver to be synchronized with those at a transmitter. Analog data channels S 1 ,..., S x  are sampled at 10 by data clocks 12 in a transmitter; the resulting pulses amplitude-modulate a carrier wave and are fed to a commutator 22 in the receiver which samples each channel at, e.g., four times the rate of clocks 12. The four samples for each pulse P (see Fig. 2) are fed to an A/D converter 24 which outputs on each channel 10- or 12-bit digital representations of the samples from 22. Thus, analog channel S 1 , for example, is converted to digital channel S 1 <SP>1</SP> (after passage through a circuit 34) which is fed via a correcting circuit F 1  or F 2  and switches 48, 50 to provide a synchronized output signal S 1 <SP>11</SP>. S 1  is also fed to a circuit 42 which determines the lead or lag E between the occurrence of the (interpolated) pulse peak and the second of the four samples for that pulse. The value of E is fed to a circuit 43 which selects F 1  or F 2  (by setting switch 48) and feeds suitable parameters thereto from stores 33-35 (by setting a switch 45) so that each F introduces a delay of L= 2T-E: the interpolated peak value code is then read out (as S 1 <SP>11</SP>) from F at the time of the fourth sample via switch 50 which is operated by a modulo-4 counter 52. Each F has a response function of the form where Z<SP>-K</SP> represents a delay of kT (see Fig. 2), R0, R1, R2 are the successive stages of respective shift registers in Figs. 5 and 6, and A 1 , A 2  or P 1 , P 2  are the parameters stored in 33-35 which are selected to provide the required delay L. F 1  and F 2  are used alternately since each requires a short "warm-up" period after selection of new parameters: the filter is fully operative when switched in by 48. The above assumes that 0#E#0À9T and that L varies from 1À1T to 2À0T in 0À1T increments provided in turn by F 1 , F 2 . If E<0 or E>0À9T (Figs. 4 or 3, not shown) then L is made equal to 1À1T or 2T respectively while the instantaneous count in 52 is respectively increased or reduced by 1; operation is then as above.

Abstract: 1392149 Safety steering columns FORD MOTOR CO LTD 16 Nov 1973 [4 Dec 1972] 53346/73 Heading B7H A vehicle has a steering column 10 rotatably supporting a steering shaft 24 wherein releasable connecting means normally securing the column to the vehicle body is constructed to disengage the steering column upon a predetermined axial force thereon, the column having a portion which is plastically deformed by a stationary part of the vehicle body after the column has been displaced forwardly by a predetermined distance. As shown in Fig. 1 the column tube 21 is secured to a support bracket 12 by support assemblies 14, 16. Projections 76 of rigid collar 68 of the assembly 14 engage grooves 78, Fig. 6, on the outer surface of tube 21. The biting action of teeth 84 of a locking washer 82 prevent rearward displacement of tube 21. A pad 33 on steering wheel 31 absorbs minor impacts. In the event of a major impact load upon steering wheel 31, as pad 33 deflects, frangible elements 27, Fig. 7, of steering shaft 24 will fracture for rearward shaft section 25 to telescope into forward section 26; hub portion 36 of steering wheel 31 engages the upper end of convoluted can 34 which collapses concertina fashion. Upon movement of tube 21 plastic members 52, 53, Fig. 4, which are bonded to inner surfaces of rubber members 54, 55 clamped in members 56, 57 of rearward support assembly 16, become axially displaced from clips 46, 47 which are retained on tube 21 by tabs 50, 51. Thus support assembly 16 provides a loose sliding support for column 21. The projections 76 of assembly 14 will then engage the rearward end of grooves 78 and plow extensions of the grooves along the surface of tube 21, to absorb the kinetic energy of the object striking the steering wheel 31. An annular housing 28 rigid with outer tube 21 rotatably supports the steering shaft 25 and also support the gear shift lever 30 which is connected to the transmission shift tube 22, Fig. 3.

A single support grid 16 is rigidly fixed to the tie-rods 5 at or near their midpoint, the other grids 7 being uniformly spaced along the fuel assembly on either side of the support grip 16 so as to ensure that expansion of the fuel pins 2 due to thermal and irradiation effects take place from the support grid 16 towards the end-plates 3, 4. In the embodiment shown, the support grid 16 is rigidly fixed to the tie-rods 5 by means of sleeves 17, 18 which surround the tie-rods and are secured to the grid 16 and the tie-rods 5 by means of spot welds 19, 19a. Since the number of fuel pins 2 is appreciably greater than the number of tierods 5 within the fuel assembly, the grids 7 follow preferentially the movement of expansion of the fuel pins 2 while sliding along the tie-rods 5.
