IPC: B41J15/06
Filed: 1937-09-30
Abstract: 487,740. Cash registers. KOOPERATIVA FORBUNDET, FORENING U.P.A. Sept. 30, 1937, No. 26489. Convention date, Oct. 2, 1936. [Class 106 (i)] [Also in Group XVI] Line-spacing mechanism ; web-feeding arrangements.-The record-strip supporting and feeding devices of a cash register are removable as a unit, being carried by a single support plate slidably mounted on a plurality of guides extending from a side frame of the machine in a direction substantially normal to the plate, the strip supporting means being such that the part of the strip in printing position is situated beneath the guide and a printing hammer and extends substantially parallel to a horizontally disposed portion of ink-ribbon. As shown, a storage roll 3 is connected to a supply roll 2 by a spring band 27, and the record strip a passes from the supply roll, around a guide stud 32, between a feed roller 1 and compression roller 18; around the feed roller and further guide studs to the storage roll. The strip is linespaced by a pawl 15 carried by a lever 13 and co-operating with a ratchet wheel rigid with the feed roller. The compression roller 18 is normally urged towards the feed roller by a spring 29, but may be held at a distance therefrom by a latch 20 during the insertion of a new strip. All the above-mentioned parts are carried by a plate 6 and are removable as a unit from the machine so that when the strip is exhausted, the unit may be immediately replaced by a second previously loaded unit. The means for attaching the unit to the machine comprise sleeves 7, 8 rigid with the plate 6 and adapted to take over rods 9, 10 projecting from the machine frame. The unit is locked in position by a cover-plate (not shown) that co-operates with the rods 9, 10. The strip is impressed against type-wheels 5 and an inkribbon b by a hammer 4 that is pivoted on the stud 10 and is pin-and-slot connected to the lever 13 so as to feed the strip during its retraction.

IPC: E05B3/04
Filed: 1936-10-01
Abstract: 476,709. Attaching knobs and handles to spindles. BURTON, G. E. Oct. 1, 1936, No. 26621. [Class 44] A door knob, attached to a spindle by rollers located in a spring-loaded slidable supporting device jamming between the spindle and the inclined faces of a sleeve fixed to the knob, has the rear portion of the supporting device bored tangentially to form a housing for the rollers which are confined against endwise movement by the shape of the sleeve. The knob a has fixed to it a sleeve b in which is slidably mounted a roller supporting device c. This device c is bored tangentially at two points to form cylindrical housings c<1> into which the rollers e can be slipped before assembly. The rollers e rotate freely and project slightly into the bore c<2> beyond the outer periphery of the device c so as to contact with the square spindle f and the flats b' formed on the conical portion of the sleeve b.. These flats locate the rollers in the supporting device and prevent relative rotation between said device and the sleeve. The releasing ring g may be used to compress spring d to release the knob or to positively move the rollers so as to cause them to j jam more tightly. A pin c<5> co-operating with a slot b<6> may be used to locate the supporting device with respect to the sleeve.
Patent GB-844760-A (GB)
Title: Improved polyester bonded-fibre fabric
IPC: D04H1/54
Filed: 1956-08-31
Abstract: 844,760. Agglutinated fibrous materials. MINNOSOTA MINING & MANUFACTURING CO. Aug. 31, 1956 [Sept. 2, 1955], No. 26758/56. Class 140. A non-woven polyester fibrous fabric having a ream weight of about 15 to 60 pounds, and comprising one or more plies of a self-unified tissue-like web having a porous open structure formed of a compacted carded mixture of drawn and undrawn staple polyester fibres which both have a length of at least one inch, the undrawn fibres being in the proportion of 40 to 60% by weight and being autogenously interbonded at their crossing points to form a network within which the drawn fibres are interlaced without being interbonded. In making the fabric the mixture of fibres may first be prepared for carding by passing through a "pickler" which blends the mixture. Thence the fibres are passed through a carding machine to form a loose open mesh web. The web passes to a heating drum having two pressing rolls mounted so as to bear against the drum, spaced apart by a distance of about two-thirds of the periphery of the drum. The web is fed into the nip between the first pressing roll and the drum and then travels along in contact with the surface of the rotating drum until it passes through the nip between the second pressing roll and the drum. The stripping of the web from the drum is facilitated by a thin coating of silicone parting agent on the surface of the drum. The web is pulled from the drum by pull-rolls through which it passes en route to a wind-up roll. The heating drum with its pressing rolls exerts a gentle pressing action upon the web. The second pressing roll is covered with a number of turns of smooth glass cloth. The undrawn fibres have a wide range of temperature within which softening takes place end autogenous interbonding may be effected. This range is below the temperature range within which the drawn fibres soften and melt. Upon heating and soft-pressing the web of mineral fibres the undrawn fibres are autogenously inter - bonded without causing the drawn fibres to soften or become interbonded ; the two types of fibres may become lightly or superficially interbonded. A twoply unified fabric may be made by laminating a previously made unified single-ply web with a second carded web. The previously made bonded web is fed into the first pressing roll nip so as to overlie the web from the carding machine, the latter web contacting the surface of the heating drum, whereby it is internally unified and simultaneously unified to the first web by interbonding of the undrawn fibres at their crossing points. The two-ply web can be made into a three-ply web, and so on, by repetition of the process. The fibrous polyester fabric may be laminated to a polyester film by passing the fabric and the film together through the pressing and heating drum apparatus, the film being on the insde and in direct contact with the drum. The film is of the drawn type and superficial autogenous interlocking takes place between the undrawn fibres of the fabric and the film.

Title: Process for the production of combustible gas
IPC: C10J3/66
Filed: 1975-06-24
Abstract: 1522365 Combustible gas production K KIENER 24 June 1975 [4 July 1974 16 June 1975] 26761/75 Heading C5E A process for the production of combustible gas from waste materials or other combustible materials comprises drying the materials and subjecting them to low temperature carbonisation at 300-600C in reactors 2, with the exclusion of air, separating resulting low temperature carbonisation gases from the solid residue in a cyclone 8 and then drawing these gases through a reaction bed 12 at a temperature of 1000-1200C, the bed being formed from a carbonaceous material and being supplied with air through ducts 14, 14a; the combustible gas produced exits via an outlet 20 at the bottom of the reactor and the ash produced in the bed 12 falls through a grate 15 into a conveyor 16. In the arrangement shown, the low temperature carbonisation gases enter the reactor 9 above the reaction bed and are drawn through it, but these gases may alternatively be introduced into the reaction bed together with the air (Fig. 2, not shown). The combustible gas produced may be used to drive a gas engine, and the exhaust gases from this engine may in turn be used to provide for the low temprature carbonisation. Where the low temperature carbonisation produces a coke having an ash softening temperature above 1200C, this coke may be used as the carbon vehicle in the reactor. Materials mentioned include domestic and industrial refuse, used oil and petroleum, wood and wood waste, peat, rubber, old tyres, asphalt, tar, oil shale, sawdust and lignite. Also described is a rotary oven for the low temperature carbonisation (Fig. 3, not shown), giving details of a water spraying system and starting burner, and a reactor for the reaction of the carbonisation gases (Fig. 4, not shown), the latter having ancillary burners for heating the reaction bed, and an air preheating and supply arrangement. Specification Serial No. 1522366 relates to apparatus for performing the process of this invention.
Patent GB-209183-A (GB)
Title: Improvements in or relating to dynamo-electric machines
IPC: H02K47/00
Filed: 1922-10-04
Abstract: 209,183. Festarini, G. M., and Metro politan-Vickers Electrical Co., Ltd. Oct. 4, 1922. Rotary converters and transformers. -A machine for converting electrical energy of one form to another form comprises one or more armatures, with windings connected to commutators or slip rings, driven by an auxiliary motor in an unwound iron ring which completes the magnetic circuit of the armature currents. In Fig. 1, two independently-driven armatures 1 in unwound field members 5 are employed for converting continuouscurrent from one constant voltage to another, the ratio of the voltages being variable. Each machine has pairs of brushes 8, 9, 8<a>, 9<a> ninety electrical degrees apart. Current from the constant voltage mains 7 produces constant voltage at the brushes 9<a>, the ratio of the voltages depending on the speeds of the armatures. Fig. 2 shows means for converting single-phase power from mains 7 to three-phase power of the same frequency. The armature has three windings connected respectively to slip-rings 14 and 15 and a commutator 3 on which are pairs of short-circuited brushes 8, 9 ninety electrical degrees apart. When the armature is driven at or about synchronous speed, three-phase, current is supplied at synchronous frequency to the mains 10. Inductances 16 may be employed to check alternating-currents between the bushes 8, 9. Single-phase power at one frequency may be transformed to polyphase power at variable frequency by a machine, Fig. 3, having three windings connected respectively to slip-rings 14, supplied from the single-phase source 7, a commutator 3 having pairs of shortcircuited brushes 8, 9, and another commutator 4 having as many brushes 17 as there are phases in the supplied netword 10. The armature is driven at or near the synchronous speed of the supply 7 and the brushes 17 may be stationary, in which case they give twice the supply frequency, or they may be driven at a speed which corresponds to the required frequency at 10. An alternative machine for giving the same transformation has single-phase supply brushes bearing on one commutator, pairs of short-circuited brushes on another commutator, and polyphase brushes on slip-rings, the short-circuited brushes being rotated at or near the single-phase synchronous speed and the armature as a whole at a speed which determines the polyphase frequency. In the form shown in Fig. 5, single-phase current fed to a slip-ring winding at 14 is converted to continuous-circuit on a commutator 9 by means of a third winding connected to a commutator 3 having short-circuited brushes 8, 8<a>. The armature is driven at synchonous speed and the brushes 8, 8<a> at or about twice synchronous speed. In all of the machines, excepting those shown in Fig. 1, two or more of the armature windings may be combined into a single winding with slip-rings and commutators as described. The field ring may have commutating poles and windings, in which case it is rotated with the brushes.

Title: Improvements relating to dough dividing and balling machines
IPC: A21C7/02
Filed: 1929-09-04
Abstract: 335,711. Pollok, J. C., and McErlane, D. A. Sept. 4, 1929. Dough diving and working machines; rolling- machines; feeding.-A dough divider and baller has a rotary male coned member 1 carrying one or more pockets 2 and an outer conical structure 3 mating with the member 1 and unitary with a hopper 4. The side wall of the hopper 4 is inclined and concaved so that it converges towards the rotating surface and thus provides a cutting-off edge. The pocket 2 has a base formed by the piston 8 moving on an adjustable non-rotary cam 10. The size of the balls of dough is varied by adjusting the height of the cam 10 by the spindle and worm gear 11, 12. As the cone rotates a mass of dough is packed into the pocket 2 by gravity and pressure while the piston 8 is at its lowest point. By the time the pocket 2 comes opposite the lower end of the spiral shell 5 the piston 8 is forced up by the cam 10 and the dough ejected into the shell 5. As the cone rotates the dough travels up the spiral being rolled into a ball and the formed balls fall from the top down a shoot (not shown). The stationary conical member 3 is supported by adjustable pillars 14 and also provides bearings 15 for the rotating cone and bearings 16 for the driving device. A rack 17 is fulcrumed to the structure near the hopper for clearing out the pockets 2 by acting on the piston 8.

Feb. 6, 1926. 0 p e n fireplaces; air supply and draught, regulating. canopies ; stoking; g r a t e s and fuelholders. - An open fireplace, adapted particularly for burning coke, of the kind in which the front of the tire is substantially vertical and constitutes the principal or only radiating surface, comprises a casing 1, 2, 3, in which is fitted a partition a, rearwardly inclined front and back grates 7, 10, and a bottom grate 9, the latter being carried in a tray 8 which, together with the grates 7, 10, are supported by lugs or brackets on the sides 1 of the casing. The partition a has an extension 15 the lower end 15<a> of which is bent horizontally as shown to coact with the rear wall 18<a> of the ash-pan 18 and so cut off the normal draught from front to back of the fire, shown by the arrows X. In any intermediate position of the ash-pan 18, part of the draught takes the normal course, and part, entering between the front of the ash-pan and the grate 9 passes direct to the back flue a<1> without traversing the fire. The upper end of the partition a is curved inwardly to form, with a removable front plate 13, a fuel magazine. A canopy is removably mounted on pivots 22 and comprises top and bottom plates 20, 25 and side members 23 which are formed with grooves or recesses 26, Fig. 5, through which any fumes escaping at the sides of the canopy can pass to the flue. A permanently open passage, which may be controlled by a damper, is formed through the canopy, which is provided with a catch 22a adapted either to maintain the canopy closed as shown in Fig. 2 or to rest on the front of the. stove top 3, in which position the canopy is held partly open to allow an updraught through the fire when the cross-draught X is cut off by the rear wall of the ash-pan 18. The back grate 10 may be formed of rods upon which are threaded blocks of fireclay w, Fig. 7, or, as shown in Fig. 8, of separate bars 29 supported at their lower ends by a tray 8 and engaging at their upper ends in recesses 28 in a fireclay block 27, the recesses being of sufficient depth to allow the bars to be moved upwardly for removal. The bottom plate 25 of the canopy may be replaced by a damper either formed as part of and operated by the canopy, or independent thereof, the arrangement being such that when the canopy is closed a small opening is left to allow any unburnt gases collecting in the magazine to escape to the flue. Instead of constructing the stove as a self-contained unit, the back plate 2 may be omitted and the flue a<1> formed between the plates a, 15, and the usual brickwork of the chimney recess into which the stove is set.

IPC: H01L21/105
Filed: 1937-10-08
Abstract: 485,528. Depositing metals by electric discharge. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 8, 1937, No. 27401. Convention date, May 29. Addition to 439,774, [Group XL]. [Class 41] [Also in Group XL] In light-sensitive devices of the type described in the parent Specification, the additional step of first coating the selenium with a metal such as cadmium, by sputtering, is commenced in an atmosphere containing water vapour and completed in a dry atmosphere. The cell is placed in a holder 26 which is adapted to be moved by means of a magnet 34 from outside the bell jar 12, so that it comes underneath the cadmium electrode 33 or platinum electrode 32. The plate 20 acts as a partition to prevent sputtered deposits from one cathode being deposited on the other. The bell jar is evacuated and argon at a pressure of about 240 microns is introduced and the sputtering on of the cadmium layer in one-second flashes separated by twenty-second intervals is commenced. After one to five flashes liquid air is poured into the re-entrant bulb 14 causing water vapour inside the bell jar to condense. When the cadmium layer permits 30 per cent of the incident light to pass, the platinum layer is sputtered on for about three-fifths the length of time of the sputtering of the cadmium.
