Title: Improvements in or relating to blasting agents
IPC: C06B47/14
Filed: 1964-05-13
Abstract: A blasting agent comprises a dispersion of a 30-80% by weight aqueous solution of nitric acid with an insensitive, immiscible, carbonaceous fuel material which is substantially unreactive with the nitric acid under normal conditions of mixing and storage, the dispersion being stable for at least 8 hours.  The fuel may be paraffin, mineral, or diesel oil, paraffin wax, vegetable oil, or powdered carbon; sucrose, molasses, or a mixture of spent activated carbon and glucose may be added as supplementary fuels. Also present may be a surface active agent, e.g. sorbitan monopalmitate, monooleate, or monostearate, a stabilizer, e.g. colloidal silica, a copolymer of methyl vinyl ether-maleic anhydride, or acrylamide or acrylic acid polymers, and a non-explosive propagation sustaining material, e.g. expanded perlite or hollow glass balls.  The explosive in slurry form may contain ammonium, potassium, or sodium nitrate.  With a high proportion of added nitrate the composition may be moulded, cast, or extruded to form a solid product.  A product having a density of over 1 gm./c.c. is formed by heating to remove entrapped air. A granular form of the blasting agent is prepared by applying the dispersion to granules of ammonium nitrate, which may first be coated with finely-divided clay, diatomaceous earth, or a mixture of sulphonates of mono- and/or dimethyl naphthalenes.  The blasting agents are insensitive to mechanical shock and are detonated with boosters or primers.

Title: Improvements in or relating to apparatus for orientating disorientated articles of mail
IPC: B07C1/20
Filed: 1958-06-23
Abstract: 845,689. Letter orientation. SIEMENS & HALSKE A.G. June 23, 1958 [June 21, 1957], No. 20059/58. Class 78 (1). Letters are uniformly orientated by means of the stamps or postmark thereon in two stages, a letter being displaced firstly about its longitudinal axis and then about an axis perpendicular thereto. Thus letters standing on their longer edge in container z, Fig. 3, are fed singly by device d so as to fall into compartments c of rotary wheel a where the letters stand on their smaller edge. The wheel carries sensing devices to sense the orientation of the stamp on the letter, and a corresponding detecting device is associated with each of the four helical shoots e1, e2 so that when the appropriate compartment c is disposed over the appropriate shoot e the detecting device operates to cause a flap to drop to discharge the letter from the compartment into the shoot. The letters are orientated as they fall down the respective shoots and are discharged uniformly orientated for reading the address, by endless belt f. Thus both the wheel and the shoots cause relative orientations of 180 degrees. Alternatively, both orientations may be performed by shoots. The detecting device may detect magnetic or fluorescent.substances incorporated in the postage stamp or postmark.

Title: Improvements in and relating to commutating rectifying apparatus for alternating currents of electricity
IPC: H02M1/22
Filed: 1926-08-16
Abstract: 278,843. Barnett, A. Aug. 16, 1926. Commutator switching-arrangements.-Relates to means for determining the polarity of rectified current obtained from a rotary commutator driven by a synchronous motor, and comprises an electromagnetically-operated switch arranged to thrdw the motor temporarily out of synchronism in the event of wrong polarity at starting. In the arrangement shown, a single phase motor having a main winding 2 and starting winding 3 supplied from the A.C. source A, B, drives a commutator 9 arranged to supply D.C. at the terminals X, Y. The starting winding 3 is arranged to be cut out when synchronous speed is attained by centrifugally-lifted brushgear co-operating with slip rings 5, 6. In parallel with this switch there is arranged an electromagnetically-operated switch 19 comprising a permanent magnet 20 and a pivoted switch arm carrying a winding 21 connected across the D.C. side of the rectifier. The switch is lightly biassed to the open position, and the winding 21 is connected so that, in the event of correct polarity, this position is maintained. If the motor pulls into step giving wrong polarity at the D.C. terminals, the switch 19 closes under the action of the winding 21, thus putting back into circuit the starting winding 3 and throwing the motor out of synchronism. The rectifier, and therefore the winding 21, are thereupon rendered ineffective, the switch 19 opens and cuts out the starting winding 3, and the motor pulls into step again. The operation is repeated if necessary until correct polarity is obtained. In the case of a commutator driven by a polyphase motor, the switch 19 is arranged to cut out of circuit one or more phase windings.

Title: Asynchronous serial printer
IPC: B41J1/30
Filed: 1971-04-19
Abstract: 1338675 Printers HONEYWELL INFORMATION SYSTEMS ITALIA SpA 19 April 1971 [29 Jan 1970] 20622/71 Heading G4H An asynchronous serial on-the-fly printer has a movable printing carriage supporting a printing head carrying a plurality of character impression members which are moved in sequence past a print hammer, the hammer being actuated during carriage movement by processing circuits in response to signals produced every time a character passes a predetermined position. Constructional details.-The carriage is driven along the print line, its position being indicated by sensing a marked disc which rotates in synchronism with the movement. Independently, the print head rotates on the carriage in front of the print hammer, its position being indicated by sensing a second marked disc rotating in synchronism with it. The print head has each character supported on an individual flexible tab, the tabs being arranged in a disc, cone, cylinder or continuous belt configuration. Two hammers (in the disc case) may be provided, each co-operating with alternate ones of the tabs which have abutments thereon, the abutments on adjacent tabs being at different radial positions. Circuitry.-In one embodiment, the carriage is moved from one printing-position to the next by accelerating it from rest for half the distance then decelerating it to rest for the remaining half of the distance. During the movement, an oscillator is switched on and feeds two frequency dividers in series (divide-by-10 and divide-by-2 in that order). A first counter with a capacity of 32 is fed from the second frequency divider while its count is in either of the ranges 2-5 and 27-31 and from the first frequency divider when in the range 6-26, via gates controlled by a decoder responsive to the count. Pulses from the character-position disc are counted in a second counter which is compared with signals indicating the character to be printed to set a flip-flop on equality. While the flip-flop is set, the first counter is fed from the oscillator direct rather than from one of the frequency dividers as above. When the first counter reaches capacity, a pulse is passed through an AND gate enabled by the set state of the flip-flop to actuate the print hammer. When the first counter reaches capacity, it is reset and the oscillator is switched off. The hammer pulse, after a delay, resets the flipflop. Thus the character may be printed when or before the carriage finishes its movement to the current printing-position. A second embodiment differs in that if the flip-flop is set by the time the first counter reaches a count of 16, the carriage is not declerated but continues to the next printing-position at constant speed, the first counter being reset to 10 in this case. The carriage-position disc may also indicate intermediate positions (besides the printing-positions) to control the counting rate of the first counter. Detection of such intermediate positions may impose pre-established counts in the first counter.
