Title: Reading appliance for scale graduations
Inventor: POPPE RUDOLF
IPC: G01D13/10
Filed: 1964-11-02
Abstract: 1,080,347. Scale reading device. FEINMESS DRESDEN, VEB. Nov. 2, 1964, No. 44602/64. Heading G2J. Light from a lamp 34, Fig. 1, is used to illuminate a scale 10, Fig. 2, which is graduated in short millimetre lines, longer half centimetre lines and still longer centimetre lines, and an image thereof is produced on a ground glass screen 5 by means of objective, 1, prism 2 and mirrors 3, 4. A mirror 9 is so positioned that the central part of the image is cut off and thus the left hand part shows only the centimetre graduation which is numbered in millimetres, e.g. 230 millimetres, Fig. 4 (not shown). The right hand part of the image shows a millimetre line which is much enlarged by lens 8 on the screen 5, and the central part where the scale image is obscured by mirror 9 has a millimetre scale (6) marked on screen 5 and illuminated from lamp 34 via lens 11, mirror 12, semi-reflector 13 and mirror 9. Thus the left hand part of the image gives the reading in tens of millimetres, the central scale (6) gives the units of millimetres and by moving screen 5 so that the right hand millimetre line image is located centrally between two index marks (7) on screen 5 the first two places of decimals are given. This movement is effected by rotating nut 16 which axially displaces sleeve 15 thus rocking a lever 14 and sliding screen 5. Simultaneously a glass circle 17 is rotated which carries numbers 0-100 arranged on four turns of a spiral and a sector (22), Figs. 3, 5 (not shown), having an inclined slot (24) therein is so rocked that the intersection of the inclined slot (24) with a radial slot (25) Figs. 4, 6 (not shown) in a fixed mask (26) defines a particular number on the spiral which is illuminated by light passing through semi-reflector 13. A coarse indication, i.e. only the first place of decimals, is given by co-operation of the inclined slot (24) with numbers 0-9 on the mask (26). The device is zeroed by actuating worm drive 31 to rotate mirror 4.

Abstract: 1,057,023. Applying tear-strips. MOLINS ORGANISATION Ltd. Nov. 12, 1964 [Nov. 13, 1963], No. 44733/63. Addition to 1,057,021. Heading B8C. To permit a tear-strip to be applied parallel to the length of a continuously moving web the mechanism of the parent Specification is modified by the provision of a second knife and transfer mechanism, so that two tear-strips in line can be applied simultaneously. In the embodiment described (Figs. 1 and 2), blades 11, 11a cut the tear-strips from a single sheet 33 divided lengthwise into two by blades 41, or from two separate sheets. Suction devices 12, 12a transfer the strips on to preformed lines of adhesive on the web 39. Heated wheels 13, 13a then secure the strips to the web. Synchronization of the cutting, transferring and sealing devices is controlled by movement of carriage 1 and feed rack 19. The carriage 1 moves from left to right along bars 2 as the tear-strip is cut and transferred to the suction devices 12, 12a. During this time the rack 19 is stationary and the blades 11, 11a and heaters 13, 13a rotate clockwise, whilst suction devices 12, 12a rotate anticlockwise, all through half a revolution. With the carriage stationary at its extreme righthand position, the rack 19 moves to the right at the speed of the wrapper 39. Blades 11, 11a suction devices 12, 12a and heaters 13, 13a complete one revolution in the opposite direction to their previous motion. During this period the tear-strip is transferred to the web 39 and secured there to by heaters 13, 13a. The carriage then returns to the left-hand position as shown, the blades, suction devices and heaters being turned through a further half revolution, and the web 39 is positioned ready for the next two tear-strips.

Filed: 1962-11-27
Abstract: 946,535. Coating with pre-formed sheets. HUMES Ltd. Nov. 27, 1962 [Nov. 30, 1961; Feb. 12, 1962], No. 44748/62. Heading B6G. Concrete articles such as hollow pipes are sealed with a plastic foil having projections on one surface by providing a sufficiently plastic surface on the article and applying the foil with pressure to embed the projections into the surface. The surface of the concrete is made suitable by proportioning the ingredients or applying mortar. A spun pipe with a basic layer 3, Fig. 1, and a surface layer 4 is produced in a mould 1. A roll of plastic foil 13, Figs. 1 and 2, mounted on a drum 15 is introduced into the pipe with the projections outermost, a length of foil unrolled and brought into contact with the surface 4 over an arc of 120 degrees, the foil aligned with the pipe axis, and clamps 17 applied. A vibrator comprising a support bar 19 carrying shoes 18 and vibrators 21 is then introduced into the pipe, with the shoes in contact with the foil, the vibrators activated and the pipe rotated on rollers 6, 10 by a handle 9. When the shoes reach the end of the foil, a clamp 25 is applied and the clamps 17 removed. The pipe is then rotated in the opposite direction. When all the foil is embedded, a further clamp is applied to the other end; or if the entire pipe circumference is covered, one end of the foil is free of projections and the ends are overlapped and welded, or the ends are welded to a strip of plain foil. The side edges of the foil may overlap the pipe ends for welding to a foil on an adjacent pipe section. Rigid pre-formed foil may be used, being inserted when slightly collapsed and then released. The vibration may be done by a rubber-coated roller. Foil can be applied also by centrifugal force.

Title: Improvements in or relating to transfer function analysis
Inventor: LEVINGE RODNEY WALTER
IPC: G05B23/02
Filed: 1968-09-20
Abstract: 1,261,355. Determining normalized phase slope. SOLARTRON ELECTRONIC GROUP Ltd. Sept.19, 1969 [Sept.20, 1968], No.44896/68. Heading G1U. To enable normalized phase slope to be determined at a given frequency for an apparatus such as a closed loop servo in whose transfer function high-frequency resonances may occur in regions of the response-frequency curve showing substantial attenuation, so that such resonances may be made more apparent a sinusoidal oscillation of frequency f is applied to the apparatus and a signal representing the phase angle # 1  between its response and the applied oscillation is derived. A second oscillation of frequency f Œ #f is then applied, #f/f being a small predetermined ratio irrespective of f, and a signal representing the phase angle # 2  between the response and applied second oscillation is derived. The difference between # 1  and # 2  is then obtained. This enables a plot of normalized phase slope (# 1 -# 2 )f/#f against frequency to be prepared, which prominently indicates any resonances in the transfer function. The apparatus 12 to be tested may be coupled to a digital transfer function analyser 13 of the type described in Specification 1,074,624. At each frequency point to be tested, a start pulse is applied at 20 to a bi-stable 17 which is set to initiate a pulse from a generator 18 to cause the analyser 13 to operate to deliver a signal # 1  in digital form corresponding to the phase lag between a sinusoidal signal e.g. at frequency f applied by the analyser to the apparatus under test and the output from the apparatus. This signal is held in a store 14. When the analyser has completed operation, it delivers a reset pulse to the bi-stable 17, which energizes a frequency shift circuit 19 to deliver a control signal to the transfer function analyser to adjust the test by an amount #f in a predetermined proportion #f/f, and also initiates a further pulse from the generator 18 to cause the analyser to operate again. The analyser operation is repeated and a second phase signal # 2  is delivered. This is subtracted from the stored value of # 1 , and the difference signal converted to radian measure and displayed at 16. A plot of such difference against frequency provides a response curve clearly indicating any resonances even if they are masked in the normal transfer function by heavy attenuation.

Abstract: <PICT:1039350/C1/1> Gases containing less than 9% by volume SO2 are catalytically converted to SO3 and/or H2SO4 comprising preheating at least part of the SO2 gases before they enter the first catalytic stage, absorbing SO3 from the part converted gases from one stage of a converter in an intermediate absorber at 170-250 DEG  C. before they enter the next stage, cooling part converted gases before they enter the intermediate absorber to operating temperature of absorber by heat exchange with outflowing gases from absorber in first heat exchanger in which outflowing gases from absorber are heated to reaction initiating temperature of next catalytic stage, i.e. 280-600 DEG  C. and then with incoming SO2 gases in a second heat exchanger. A temperature difference of at least 100 DEG  C. may be maintained between the entry temperature of the cooling SO2 gases and the outlet temperature of the cooled SO3 gases.  Referring to Fig. 1, the incoming SO2 gases pass into intermediate heat exchanger 6, 7 and 10 and then into the converter with several contact layers on trays 33. Gases from a sulphur combustion stove may be added at this point to supplement the SO2 content of the incoming gases.  Partly catalysed gases pass into heat exchanger 10 and then enter the second catalytic layer. These gases are then cooled by heat exchangers 5 and 7 and the SO3 present is absorbed in the intermediate absorber 18.  The gases deprived of SO3 are heated in 5 before passing into the final stage of the converter 33.  They are then cooled in 7 and passed to the final absorber 21 into which the charged washing acid from the intermediate absorber 18 overflows freely. The intermediate absorber may consist principally of a ceramic material.
