Abstract: 1,068,824. Simulating networks. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. April 3, 1964 [April 16, 1963], No. 14879/63. Heading G4G. [Also in Division H3] A function generating circuit (Fig. 1) comprises a curve forming network including a network of resistors 4-7 and biased rectifiers 8-11 which acts so as to provide different effective resistance for different values of the input voltage E, the network including a first resistor 4 which is always effective; a unity gain amplifier 3 of high input impedance and giving no phase reversal and having its input connected through the first resistor to the circuit input, and a further resistor 13 connected between the output of the amplifier 3 and the input of the circuit. The circuit is intended to simulate by direct electrical analogue a water or gas distribution network, where the law connecting the head loss H and the flow Q is H=rQ<SP>n</SP>, r being the hydraulie resistance of the pipe and n being approximately 2, more exactly 1À85. In the electrical simulating circuit, E, the E.M.F. applied across the circuit, represents H and I, the current flowing into the circuit, represents Q. The arrangement of resistors 4-7 and biased diodes 8-11 is chosen such that it produces a voltage current characteristic which is a piece-wise synthesis of the desired power law-as the input voltage E is increased, successive diodes 8, 9 &c. are cut off, so that the effective resistance is increased and a non-linear characteristic results. The resistor 13 connected back to the input through the unity gain amplifier enables the factor r to be allowed for, and by varying the resistor, networks showing different r factors may be simulated. A detailed circuit for the amplifier 3 is explained (see Division H3) and arrangements are incorporated which switch off the input to the simulating circuit if overload or reverse current conditions arise (Fig. 2, not shown).

Title: Signal recognition system
IPC: G06V30/224
Filed: 1972-03-30
Abstract: 1337898 Selective signalling INTERNATIONAL STANDARD ELECTRIC CORP 30 March 1972 [8 April 1971] 15078/72 Heading G4H A signal recognition system recognizes the presence of at least two successive input signals, spaced by a time interval T1, by effectively comparing this interval with an interval T2<T1 between successive clock pulses, to produce a further signal when N1. T2 < T1 < N2. T2 where N1 and N2 are predetermined positive integers such that N2 > N1 > 1, these further signals being counted, a count of at least two generating a recognition signal. The input signals are shifted into a (N2 + 1)-stage shift register by the clock pulses and logic responsive to the shift register stages produces the further signal when a 0 is present in the first and any one of the last N2-N1 + 1 stages of the register, the 0 being immediately preceded by a 1 in each case ("preceding" means nearer the register input), but there being no such 0 preceded by a 1 in any pair of consecutive stages lying between the two pairs holding 10. N2 may equal N1 + 1 or N1 + 2. The further signals are counted as stated, a recognition signal being registered on a count of at least 2, e.g. 4. A modification shortens the shift register to 3 stages by using a clock-pulse driven counter which is reset when 10 is detected in stages 2 and 3 of the register, the further signal being produced when detection of 10 in stages 1 and 2 coincides with a count between N1 and N2 in the counter. The system may be used in reading a stamp including a series of vertical bars on a moving document.

Filed: 1933-05-25
Abstract: 417,538. Printing machines. GOSS PRINTING PRESS CO. OF ENGLAND, Ltd., and SMITH, E. J., 18, Whitefriars Street, Fleet Street, London. May 25, 1933, No. 15200. [Class 100 (ii).] Inking-apparatus.-An inking fountain, particularly for rotary newspaper presses, is divided into a number of compartments each of which is adapted to supply ink to a different zone of the fountain roller, the compartments being supplied with ink from a common container. The arrangement permits of ink being supplied to one or more page lengths of the roller according to the width of the paper being printed. The fountain 4 is divided longitudinally by a partition 5 into two compartments one of which contains the fountain roller 6 and is subdivided along the length of the roller into compartments of one page width by partitions 7 closely engaging the roller or engaging grooves formed therein. The other compartment 9 formed by the partition 5 forms the common ink container and communicates with each of the smaller compartments through openings in the partition 5 controlled by disc valves 10 actuated by handles 12 or by gearing from the side of the press. Thus the supply of ink to any one or more of the small compartments may be cut off by actuating the appropriate valve 10. When thus cut off, the ink remaining in the compartment may be returned to the compartment 9 through a filter 19 by means of a pump 14 and valves 16, 18, foreign matter settling in a chamber 20. Instead of the pumps 14, a reservoir cylinder may be provided in the bottom of each small compartment, a piston being provided in the cylinder. When the compartment is out of use the piston is lowered to draw the ink into the cylinder. The ink is returned to the compartment when required by raising the piston.

Title: Automatic Wear Compensation Devices for Friction Brakes
IPC: F16D65/54
Filed: 1968-03-29
Abstract: 1,197,364. Automatic adjusters for disc brakes ; brake cylinders. MESSIER. 29 March, 1968 [30 June, 1967], No. 15264/68. Headings F2E and F2F. A device for compensating for the wear of the friction lining of a brake comprises a cylindrical tube 6, Figs. 1a, 3 (latter not shown), provided with longitudinal slots so that it is radially elastic, attached to one part, e.g. fixed part 1, of the brake. A rod 11 of circular crosssection having an enlarged head 12, e.g. of frusto-conical cross-section, Fig. 4 (not shown), is located within the tube and a ring 15, Fig. 5 (not shown), having a similarly contoured inner surface to that of the end of the rod 11 is arranged round the tube 6. The relative dimensions of the tube 6, ring 15 and head 12 are such that the smallest diameter of the ring is less than the largest diameter of the head plus twice the wall thickness of the tube so that the movement of the ring to the LHS under the action of compression spring 18 causes the tube 6 to be clamped between the ring and rod. The ring is located between two collars 8, 9 on a member 2 attached to a second pair, e.g. the movable part carrying the friction lining 3, of the brake, spaced apart by a distance equal to the working clearance of the brake. In operation, for an unworn friction lining, the member 2 moves such that the opposed surfaces of the collars 8, 9 just contact the ring 15. If wear occurs resulting in an increased clearance of u, at the end of the movement of member 2 to the RHS the ring 15 is engaged and moved forward by the distance u, resulting in the releasing of the tube 6. Under the force of spring 18 the rod 11 is moved to the LHS until the tube is again clamped between it and the ring thus taking up the extra distance u. On release of the brake, the member 2 will then move back to its initial position. As applied to a disc brake, Figs. 2, 6 (latter not shown), in which one or a plurality of discs 4 are gripped between friction linings 3 subjected to a force from an hydraulically operated piston 2 in cylinder block 1, the ring 15 moves between an abutment nut 8 and ring 9 mounted on the piston and the tube 6 is bolted to the cylinder block. The rod 11 is at its RH end screwed into a socket 13 between which and the ring 9 the restoring spring 29 of the piston is mounted. When the friction lining is replaced the clamping action of the rod 11 and ring 15 is released by pushing the rod 11 to the LHS by a screw (43) provided on a flange (41) which when screwed in pushes on the release plug 31 which in turn pushes on the socket 13. The cylinder block is provided with additional cylinder 22.

Title: Improvements in and relating to means for the automatic control of the production ofa product, depending on the change produced in radiant energy by the presence of undesirable substances in the initial material
IPC: G01N21/85
Filed: 1919-06-18
Abstract: 151,328. Logan, L. June 18, 1919. Controlling chemical processes; gas analysis; testing, chemical; sulphur trioxide, catalytic production of.-In apparatus for regulating the production of a product, a sample of the initial material is withdrawn and is passed to a testing- apparatus which acts in such a manner that the presence of an undesirable substance in the sample causes a variation in the quantity and character of radiant energy such as light projected through the apparatus, and the variation so produced is utilized to operate means controlling the process of production. The invention is described with reference to the manufacture of sulphuric acid by the contact method, the control depending on the presence of arsenic in the reaction gases. Thus, a sample of the gases is passed to an electrolytic Marsh apparatus 5, the gases from which after purification in a tube 9, are burnt at the jet 11, the flame impinging on a quartz, glass or like transparent screen 12 arranged between a source of light 16 and a lightsensitive cell 15; if arsenic is present, a mirror is formed on the screen 12 and serves to cut off more or less the light falling on the cell 15. The latter is in circuit with a relay 32, and the increase in resistance in the cell 15 consequent on the cutting off of the light actuates the relay to close a circuit 29 and to energize the solenoid 28 controlling through a valve 26 the supply of fluid under pressure in the pipe 25; opening of the valve 26 actuates a piston 23 which in turn operates the main three way valve 14, so that if arsenic is present in the gases, these are bypassed back to the purifying-apparatus 3. The screen 12 is periodically cleaned by a wiper 34, and if the impurity is no longer present, the relay 32 comes into action to open the circuit 29 and to deenergize the solenoid 28, and the valve 14 then returns to its original position to pass the gases to the contact apparatus 1. In other instances, for example in the case of liquids, the control may be based on the extent to which the plane of polarization of light is rotated, or on variations in the refractive index; or it may depend on the fact that the objectionable constituent yields a coloured product on treatment with a chemical indicator, in which case a source of light of the complementary colour would be employed.

[Class 83 (iii)] In a gear-cutting machine for the continuous generation of a curved tooth bevel gear h by means of a face milling cutter c rotating in timed relation to the blank, the cutter cradle g and the work headstock 6 are mounted in frame members 11, 10 respectively, forming parts of a closed rectangular structure and pivoted together on an axis WW passing through the blank cone apex. The cutter spindle is eccentrically mounted in a cylinder i which is itself eccentrically mounted in the cradle to which generating movement is imparted by worm gearing f. Thus, by rotating the cylinder i in the cradle the distance between the cutter spindle axis and the basic crown gear axis may be adjusted. The cutter spindle is driven through gears p, q, spindle r, gear s and either an internal gear t or an external gear so that the speed of the cutter head may be varied. The pivoted base slide 2 carries a standard 4 having bearings for the work spindle 5. The headstock 6 is adjusted along guides 7, 8 by means of a screw 9 and is clamped at 15 to the frame member 10 after adjustment. The worm wheel 16 by which the blank is driven is secured to the front of the spindle 5 close to the blank so as to avoid torsional errors in the work rotation.
