Abstract: 1281128 Digital-analog converters BECKMAN INSTRUMENTS Inc 25 Feb 1970 [26 March 1969] 8970/70 Heading G4H In a digital/analog converter in which the current applied to the inverting input of an integrated circuit operational amplifier 16, (Fig. 1), (attached to a non-conductive box member), and consequently the voltage at output terminal 18, depends on which of a set of parallel resistors 14 (deposited on the box member) are connected via integrated circuit transistor switches 54 controlled by the digital input terminals 6, 8 to a ground line 26, the voltage drop across switches 54 when conductive is compensated by a voltage and temperature compensation circuit 29. The circuit 29 comprises a Zener diode 34, diode 30 and transistor 19 connected between the non- inverting input of the operational amplifier and the ground line 26 the net temperature coefficient of these three components being such that the voltage across the resistors 14 is constant. Either transistor 19 or diode 30 may be omitted. To prevent current flow through a resistor when the associated transistor is not conductive lines 43 and 15 are kept at the same potential by a diode 38 which is selected so that the voltage drop across it is the same as the voltage drop across the base emitter of the transistor 44. The resistor 52 provides a constant polarity offset current to shift the analog output voltage of the terminal 18 to a desired point of reference. The temperature coefficients of the resistors 14, 52 and feedback resistor 17 are matched. They are fabricated as deposited layer resistors in the non-conductive base member.

Title: Improvements in or relating to road roller vehicles
IPC: E01C19/26
Filed: 1935-03-25
Abstract: 439,148. Road rollers. FLAMAND, S., 5, Naestvedvej, Ringsted, Denmark. March 25, 1935, No. 9279. Convention date, May 15, 1934. [Class 6 (i)] [See also Group XXXI] In a road roller having three or more roller axles disposed one behind another, the frames of the rollers are made angularly displaceable relatively to one another in a horizontal plane in such a manner that when adjusted for traversing curves, the individual rollers take up positions such that their horizontal middle lines perpendicular to their axes become tangents to a common circle, the point of contact of each tangent lying substantially in the corresponding axis. Each roller a is joumalled in its own frame b which may form part of the chassis of the road roller. The three frames b may be connected by vertical hinges c midway between the axes of the adjacent rollers. The weight may be equally distributed over all the rollers. Steering is effected by rotating a jointed shaft d at a distance laterally from the hinges, the shaft being mounted on the central frame b and being threaded to engage swivelling nuts e on the other frames b. The shaft d may be rotated by hand by means of chain gearing, or may be coupled to a power-driven shaft l by means of reversible friction gearing t, a shaft v, and bevel gearing x. The shaft l is driven from the engine through variable gearing k and drives all the rollers through worm gearing n and chain gearing p. It is universally jointed above the hinges of the frames b. The individual rollers may each comprise two parts driven differentially. The hinges c may be dispensed with, the frames of the front and back rollers being movably supported in curved guides in the chassis.

Title: An improved device for obtaining a measurement of the colour or opacity of a fluid
IPC: G01N21/03
Filed: 1955-03-30
Abstract: 788,803. Measuring transmissivity of fluids photo-electrically. CANDY FILTER CO., Ltd., and AITKEN, R. W. Jan. 9, 1956 [March 30, 1955], No. 9296/55. Class 40 (3). [Also in Group XX] A photo-electric device for the measurement of the colour or opacity of a fluid includes at least two chambers arranged for the independent flow of a reference fluid and a test fluid, each chamber having window openings in opposite faces for the transmission of light from a source, through the chambers and thence to independent light-sensitive devices. Each window opening is covered by an eccentric part of a transparent plate which can be rotated to prevent deposits or stains, the construction being such that there is substantially no leakage of fluid. The apparatus is such that comparative readings of the colour or opacity of the reference and test fluids can be obtained from the outputs of the light detectors. Two transparent plates 5 are rotatable by a drive 11 through a gearbox 3 and are clamped by nuts 6 and washers 7 against shoulders formed by intermediate shaft sections such as 4a. The fluid chambers 15 have openings in the side faces of blocks 14, and flexible rings 17 in concentric annular channels 16 prevent leakage, each chamber opening being closed by a window formed by part of a transparent plate 5. Members 20 connect blocks 14 with the fluid supply circuits so that fluid from a member will flow via an aperture 22, a passage 24, a groove 18, a bore 15 and thence out in the reverse sequence. Light from an electric bulb in casing 27 is projected by two lens and mirror systems and iris diaphragms through the two fluid chambers, and is detected by photo-electric cells 33 after traversing filters 34. The photo- - electric cell 33a pertaining to the reference fluid is connected to a slide wire 35 of a recording potentiometer 36, the pointer 37 of which is connected to photo-electric cell 33b pertaining to the test fluid. Reference has been directed by the Comptroller to Specification 692,675.

Abstract: 1380672 Making corrugated waveguides KABEL-UND METALLWERKE GUTEHOFFNUNGSHUTTE AG 26 Feb 1973 [27 June 1972] 9300/73 Heading H1W In order to obtain uniform corrugation in the manufacture of an elliptical, corrugated waveguide, the shaping rollers 10, 11, which impart an elliptical section to the circular, corrugated tube 8, are driven at a speed determined by the draw-off speed from the corrugating device 7. To this end, the speed of the motor 14 driving roller 11, is regulated by a roller 15 which rides upon the tube 8 and responds to the degree of slackness in the tube. By this means a uniform draw-off speed may be obtained. The apparatus also includes means 3 for forming a metal strip 2 into a slit, circular tube, means 4 for welding the slit and means 5 for feeding the welded tube to the corrgating device. The corrugating device 7 imparts an axial rotation to the tube of between 30 and 60 degrees whereby the welded seam lies between the major and minor axes of the final elliptical cross-section.

Patent GB-1462741-A (GB)
Title: Focus detector
IPC: G02B7/36
Filed: 1974-03-01
Abstract: 1462741 Determining focal plane photo-electrically ASAHI KOGAKU KOGYO KK 1 March 1974 9383/74 Heading G1A Apparatus responsive to the focal sharpness of a lens comprises a photo-cell fixed relative to a predetermined focal plane and producing an output representing focal sharpness; a resonant circuit driven by a fixed-frequency oscillator; means for varying the resonant frequency of the circuit in response to the photo-cell output; and means responsive to the resonant circuit output. The resistance of a C & S photo-cell attains a maximum P 1  Fig. 1 when an image formed thereupon by a lens becomes sharply focused. The photo-cell 5, Fig. 2, causes a direct potential to be applied to a variable-capacitance diode 13 forming part of a tuned circuit 9 coupled to a fixedfrequency oscillator 8 and driving a transistor 14 connected to a threshold-level potentiometer 17. Thus a meter 18 controlled by the transistors 14, 16 passes current only when the plane of the image approaches the photo-cell 5, and gives a peak reading when the image is sharply focused. Compensation for variations in image brightness may be provided by a second photo-cell responsive to  diffuse light from the image and effective to vary the aperture of a diaphragm in the path of the first photo-cell Fig. 5 (not shown); or to alter the setting of a potentiometer fed with current responsive to the first photo-cell Fig. 6 (not shown); or to oppose the first photo-cell in a differential amplifier Figs. 4A, 4S, (not shown) of a second embodiment. In a third embodiment, Fig. 8, the photo-cell 405 is so displaced that, when the image is focused on the predetermined plane, the photo-cell resistance corresponds to a point P 2  of maximum gradient on the curve of Fig. 1. The photo-cell 405 simultaneously controls two tuned circuits 409, 409' arranged to resonate at the frequencies of respective oscillators 408, 408 when the photocell resistance deviates a small amount respectively above and below the optimum P 2 . At that optimum neither tuned circuit resonates, neither of two lamps 424, 424' is lit, and a motor M is stationary. A small deviation in focal sharpness causes one circuit 409 or 409' to approach resonance, so that one lamp 424 or 424' lights and the motor M drives mechanical means to adjust the lens. In a modification Fig. 9 (not shown) the two staggered tuned circuits (509, 509') are each controlled by a separate photo-cell (505, 505') placed respectively on one side and the other of the predetermined focal plane.

Title: Electronic apparatus for high-speed printers
IPC: G06K15/06
Filed: 1957-03-22
Abstract: 825,782. Selective printing. GENERAL, ELECTRIC CO. March 22, 1957 [Aug. 27, 1956], No. 9428/57. Class 100(4) A high-speed printing machine comprises a line length of columns of characters, each column of which is successively moved through a printing position and as each character reaches printing position, equivalent first signals are sensed on a code wheel 14 by a sensing head 18 and are compared with second or input signals 22 in a coincidence device 40 whereupon identity of signals actuates a hammer-control apparatus to print on a paper web 26a through ink-ribbon 26. For each line of characters there are a plurality of coincidence devices 40, fed by two-part registers 30A, 30B into which the printer input signals are successively entered and circulated. In the embodiment described the characters are on a drum 10, required to make one complete revolution per line, and the paper advances one line after each revolution of the drum. A seven bit binary code is used and each register can hold 84 bits (twelve characters) 42 bits in each part which are circulated simultaneously so that the contents of the registers for a line of type is scanned in much less time. Circulation is enabled by a shift pulse generator 39 and occurs from the centre of the register to the front end and from the back end of the register to the centre. The shift pulse generator 39 is connected to the seven outputs of a bitphase ring counter 37. After the output of the counter is filled, it is applied via an AND gate 34, to a column-phase ring counter 38 which can count a total of six counts before it returns to its initial position to deal with the seventh character of the line. The outputs of counter 37 are applied to other AND gates 50A- 50F. The first signals, for comparison purposes, are applied from the code wheel 14 to all the coincidence devices 40A, B simultaneously and outputs from the coincidence devices 40A, B are also applied to the AND gate 50A-50F. Flip-flops 52A-52F are connected to each AND gate 50A-50F, and to the outputs from the column-phase ring counter 38. The coincidence device 40A, if it finds that the contents of register A and the code-wheel indications are identical, applies its output to all AND gates 50A-50F simultaneously. However, since only AND gate 50A has the required enablng input from the column-phase ring counter, only it will be enabled to provide an output which drives the associated flip-flop 52A. If the flip-flop 52A has been driven to its set condition, it is enabled to prime for firing an associated thyratron valve 56A, which, when subsequently fired by a pulse from the source 62, can energize a hammer which prints a character at the column position for that hammer. Another required input to AND gate 50A before it can drive the flip-flop 52A, is an output from a non-zero on the code wheel 14. This controls circuitry so that zeros which have no significance are not printed.
