Title: Metal slab treating apparatus and method
IPC: B21B45/00
Filed: 1973-10-04
Abstract: 1430977 Conveyers; rotating loads AF INDUSTRIES Inc 4 Oct 1973 [13 Nov 1972] 46429/73 Headings B8A and B8H [Also in Divisions B3 and C7] A metal slab treating apparatus comprises a base 18, a pair of independently rotatable slab supporting leaves 1,2, each pivotally mounted at 69 to the base 18 to rotate toward the other for transferring the slab 130 from one leaf to the other, means 74 for independently rotating the leaves 1, 2 and a platform 96 carrying a slab treating tool 122 and mounted for rotation and three directional movement relative to the leaves 1, 2. The base 18, formed from beams 20, is mounted on a concrete bridge 16 positioned in a pit 10. Each leaf is formed from longitudinal beams 26, 28 connected by transverse beams (30, 32, 34, 36) (Fig. 2, not shown), the beam 26 mounting slab stops 46. Each leaf is pivotable by hydraulic cylinders 74 which are pivotally mounted to the base 18 and the piston-rods 80 of which are pivotally mounted to the leaf. Located at the two outer corners of each leaf are spring bumpers (Fig. 9, not shown) which act as shock absorbers when the leaf supporting a slab 130 is lowered into a horizontal position. A pulpit 96 for the operator is rotatably mounted to a carriage 102 which is movable along transverse rails 104 which are in turn longitudinally movable along girders 106. The pulpit 96 is movable vertically by cylinders 98. The slab 130 is delivered to and removed from the apparatus by roller conveyers 128, 132 and is lifted on to and off the leaves 1, 2 by an electromagnet 120. When the apparatus is used to scarf a metal slab 130, the latter is lifted by the electromagnet 120 from the conveyer 128 on to the leaf 1 whereupon the leaf 1 is inclined by the cylinders 74 to enable an operator in the pulpit 96 to scarf the slab using a torch 122 pivotally mounted to the pulpit 96. When the slab surface has been scarfed, the two leaves 1, 2 are moved into parallel relationship and then moved together anticlockwise to transfer the slab 130 from the leaf 1 to the leaf 2 to enable the other surface of the slab 130 to be scarfed. The slab 130 is lifted by the magnet 120 on to the conveyer 132 upon completion of the scarfing operation. If the apparatus is to be used to quench a hot slab 138, Fig. 11, the leaves 1,2 are provided with water pipes 134 having spaced jets 136. The slab 138 is raised into the vertical position by the leaves 1, 2 so that the jets 136 are directed at the top and bottom surfaces of the slab 138. The apparatus may also be used for grinding and hand chipping the slab 130.

Abstract: 1398977 Gas detector EMI Ltd 4 Oct 1972 [7 Oct 1971] 46573/71 Heading G1A A non-dispersive infrared gas detector is used in a fire and/or intruder alarm system. Radiation from a tungsten filament lamp 2 is internally reflected along an internally reflectively coated tube towards a lead selenide cell 5. An interference filter 4 allows infrared only to reach the detector. Ingress of e.g. CO 2 , CO, methane via entries 21 or apertures at 22, causes absorption of radiation and an alarm, audible and/or visible, to be actuated if the amplitude change or rate of change is sufficient. CO 2  is indicative of a fire, an intruder's breath or use of heat generating apparatus. The filter 4 is chosen for the gas to be detected. A multi-channel arrangement for detecting two or more gases may be provided by a segmented structure and plurality of filters. A filter wheel and single detector may be used. The lamp output is modulated and a tuned amplifier 8 used, to reduce noise. A phase sensitive detector circuit 9 is coupled to the amplifier.

Title: Apparatus for attachment for an engraving machine or to a colour scanner
IPC: H04N1/393
Filed: 1968-10-01
Abstract: 1,247,036. Facsimile apparatus. DR.-ING. RUDOLF HELL. 1 Oct., 1968 [18 Oct., 1967], No. 46622/68. Heading H4F. The invention relates to an apparatus for attachment to a drum-type facsimile machine in order to provide a continuous adjustment of the relative size of the original and reproduction. The rotating shaft 1 of the drum on which the reproduction is supported, is equipped with a cam 14 which imparts an oscillation to a shaft 10 via a bar 16, pivoted at 19. Shaft 10 is axially fixed with respect to shaft 1 and is supported in two bearings 8 and 9, fixed to a slide 7 which is capable of movement in a direction A parallel to the length of shaft 10. This shaft is also equipped with an arm 11 which is fixed to rotate oscillate with the shaft but is movable therealong. Arm 11 also supports the original transparency 13 to be scanned. A scanning head 2 of the photoelectric type is attached to a base-plate 6 which is moved in the direction A parallel to the axis of shaft 10 in correspondence with the movement of the recording head (not shown) the original 13 being illuminated by light passing along a tube 4 from a tube 5 fixed to scanning head 2. A bar 21 is slidably mounted to the scanning head 2 at 23 and 24 and is caused to rest against and slide along a rail 28 at one end, and a rail 20, fixed to slide 7, at the other. Rail 28 is fixed with respect to the machine bed (not shown) for each scanning operation, but is pivoted at 29 such that it may be adjusted for the required relative size between original and reproduction. Movement of the scanning head 2 in the direction A hence causes slide 7 to move in the same direction at a slower or faster speed depending upon the angle at which rail 28 is fixed. As the scanning head moves, shaft 1 rotates and causes the original 13 to oscillate across the head 2. Hence the horizontal relative size between original and reproduction is varied by means of the angle of rail 28, while the vertical relative size is varied by altering the position of the pivot point 19 of bar 16 which varies the magnitude of the oscillation of the arm 11.

Filed: 1970-10-05
Abstract: 1,273,870. Digital transmission systems; signal averaging. MULLARD Ltd. 5 Oct., 1970, No. 47229/70. Heading H4P. In a signal averaging arrangement for enhancing the signal to noise ratio of repeatable signals by continuous summation in a store, to reduce the size of the store the summation is repeatedly reduced by subtraction of a fixed amount at a repetition rate having a determined relation with the value of a summation at any one time. The fixed quantity may be of the same order as the least significant quantizing digit. The subtraction, which is in the form of a feedback signal may be fed to one input of a differential comparator and a random, pseudorandom or quasi random signal is fed to another input. The comparator may be of integrated type. The output of a comparator may be used to control a subtractor which either subtracts the fixed amount or leaves the stored signal unchanged according to whether the output of the comparator is above or below a given level e.g. a 1 or a 0. If an analogue feedback signal is employed then the random signal can be any suitable noise or quasi noise source and the comparator is arranged to give a digital output from the analogue inputs. A preferred noise source should have a rectangular probability distribution thus making the probability of subtraction linearly proportional to the feedback signal but other distributions may be employed so long as the average number of times the subtraction is made is related to the feedback signal in the manner required.

Title: Clock pulse generators
IPC: G06F1/04
Filed: 1966-10-27
Abstract: 1,136,342. Clock pulse generators. INTERNATIONAL BUSINESS MACHINES CORP. 27 Oct., 1966 [17 Dec., 1965], No. 48179/66. Heading G4A. A clock pulse generator comprises means for generating an ordered sequence of electrical pulses and a plurality of latch circuits each actuated in response to the generation of a respective one of a plurality of said pulses and inhibiting means operative to inhibit generation of a pulse in response to non-actuation of the latch circuit corresponding to the expected preceding pulse. A clock pulse generator comprises four NAND latches L1, L2, L3, L4 two delays 5, 32 and various NAND gates, inverters and amplifiers. In response to a pulse 12 on a "single cycle" input, the generator performs one cycle during which it produces first, second and third output clock pulses on respective output lines in turn. The single-cycle sequence is shown schematically in Fig. 2. In this, apart from the two boxes "I2 rise" and "I2 fall" which "produce" output signals when the I2 input pulse rises and falls respectively, each box performs the function named therein and "produces" a signal on each of its outputs, when all its inputs have signals thereon. If a pulse is applied to a "free-running" input rather than the "single cycle" input, a series of whole cycles will be performed ending at the end of the cycle during which the input pulse ends. In this mode, production of the third output pulse is a necessary condition for resetting of latch L2 which is a necessary condition for the subsequent setting of latch L1 to start the next cycle. Hence in both modes, production of each output pulse is conditional upon production of the preceding. If, due to malfunction, one of the three outputs remains on while the next output comes on, the clock will stop at that point. If a signal is applied to an "inhibit" input, the clock freezes on its current output and when the signal is removed continues from that point. If a pulse is applied to a "reset" input, the latches L1, L2, L3, L4 are reset. Three further inputs are provided for causing the clock to freeze on the next first, second and third output pulses respectively, the clock continuing where it left off when the input signal is removed. Six terminals (P, Q, R, S, T, U) are provided in the circuit which can be connected together in pairs to positively ensure non-overlapping of the output pulses. If a pulse on the "single cycle" or the "freerunning" input rises and falls while the third output pulse of a cycle is being generated, it nevertheless sets the latch L1 and will initiate the next cycle when the present cycle ha s  finished. The invention may be used in a computer for gating data and control information

Abstract: 1522479 Regulating nitrogen supply to methane fermentations BRITISH PETROLEUM CO Ltd 23 Oct 1975 [7 Nov 1974] 48210/74 Heading C6F A process for increasing the cell density of a culture having a low density of cells of a methane utilizing micro-organism, inhibited by or sensitive to the presence of nitrogen in combined form, involves cultivating a cell or cells of a methane and elemental nitrogen utilizing micro-organism in a broth comprising an aqueous nutrient medium which does not contain nitrogen in a combined form, or in which the concentration of nitrogen as nitrogen in a combined form is less than or equal to the nitrogen content of the cell mass, adding to the broth air, methane and nutrients which are essential to the micro-organism for growth, with the exception of nitrogen in a combined form, in quantities which permit unrestricted growth of the microorganism, measuring either intermittently or continuously the rate at which nitrogen is converted  into cell mass and thereafter adding nitrogen in a combined form to the broth in quantities which are equal to or less than the rate at which nitrogen is converted into cell mass. The methane may be supplied as natural gas, elemental nitrogen as air for aeration and combined nitrogen as ammonium or nitrate ions. The concentration of dissolved oxygen in the broth is preferably maintained in the range 0À05-0À5 milligrams per litre (maximum 3À0 milligrams/litre). The rate at which nitrogen is converted into cell mass may be ascertained by determining the quantity of cell mass produced in unit time e.g. by reading the optical density of a sample with a spectrophotometer, and calculating the amount of nitrogen in this cell mass from a knowledge of the nitrogen content of the cells of the strain of micro-organism present. The initial cell density is typically in the range 0À05-1À5 grams (dry weight) per litre. An Example is directed to the cultivation of the strain Methylococcus capsulatus ATCC 19069. However, a mixed culture obtained from a natural source e.g. mud from stagnant pools, and including some associated micro-organisms which are not capable of utilizing methane and elemental nitrogen, may be employed.
