Title: Improvements in copying machines
IPC: B41L9/04
Filed: 1927-05-28
Abstract: 294,328. Gledhill, A. H. May 28, 1927. Copying documents, drawings, and the like.- Improvements are described in machines for copying documents, drawings, &c. of the kind comprising an impression roller A, Fig. 1, mounted in pivoted arms a' in a carriage E, which is reciprocated by hand over a duplicating- composition supported on a flat bed, the roller A, in the inoperative position, being raised off the bed and separated from a co-operating, spring- pressed feed roller B, so that a sheet may be inserted between these rollers and up to a front stop, whereupon the roller A is swung down and the sheet is fed out between the rollers as the carriage travels across the bed. (1) To prevent premature engagement between the rollers A, B with consequent forming of a loop of paper in front of the roller A, a promotion b<1>, Fig. 4, is provided on each one of a pair of arms b supporting the roller B, and each arm a' engages a projection b<1> to separate the rollers until the roller A almost arrives at the operative position : the projections b<1> then drop into recesses a<2> in the arms a<1> and allow the rollers to engage. (2) To adjust the pressure of the roller A on the duplicating-composition, and to allow this roller to adjust itself to inequalities in the composition, the carriage is supported at each side on spring-pressed plungers D, Fig. 1, bearing on paths f at the sides of the machine, the pressure being adjusted' by turning screws d. A rough adjustment may be effected by means of the grub screw usually provided in this type of machine. (3) To avoid distortion of the roller A and to cause it to bear uniformly over the whole width of the sheet, a screw adjustable roller C, Fig. 6, is arranged to bear on the roller A at one or more intermediate points.

Title: Process for the polymerization of olefine oxides
IPC: C08F4/00
Filed: 1961-04-21
Abstract: The process of polymerizing olefin oxides according to the parent Specification, in which reaction products of alkaline earth hexammoniates with olefin oxides and nitriles are used as catalysts, is modified by polymerizing in the presence of an organic nitrile and an inert normally-liquid organic vehicle other than a nitrile.  The molecular weights of the products are thereby reduced.  Specified nitriles are aceto-, propio-, butyro-, valero-, isovalero-, capro-, caprylo-, capri- and pentadecane-nitriles.  Suitable organic liquids are aliphatic and aromatic hydrocarbons, dialkyl ethers, anisole and ethers of alkylene glycols.  Many olefin oxides are specified, most preferred being ethylene and propylene oxides and 1,2- and 2,3-epoxy butanes.  The amount of nitrile is preferably 5 to 100% by weight of the metal in the catalyst and 0,001 to 0,5% by weight of the organic liquid.  The latter is preferably in amount of 5 to 95% by weight of the total epoxide and vehicle.

Title: An improved method of and machine for joining metal strips
IPC: B21D39/03
Filed: 1952-06-11
Abstract: 702,443. Riveting; punching. AKTIESELSKAPET. NORDISK ALUMINIUMINDUSTRI. June 11, 1952 [June 11, 1951], No. 14688/52. Class 83 (4) A machine for joining metal strip ends wherein at least one hole is made in the two strip ends as they overlap each other and whereupon the burrs thereby produced are turned over comprises co-operating jaw members for clamping the strip ends and at least one set of puncturing and turning-over punches and driving means connecting the punches to a driving shaft in such a manner that the clamping, puncturing and turning-over actions are effected during one single revolution of the driving shaft. The machine frame 11 supports a lower stationary clamping jaw 12, a movable top clamping jaw 13, a set of puncturing punches 3 and turning- over punches 4 and a driving shaft 14. Two cam discs 17 having a cut-away segment 19 are mounted on a shaft 14 and each disc engages a pivoted slab 20 supported by a transverse beam 23 through the medium of a roller 22, the beam being supported in the frame by springs 24. The beam is also connected to the top clamping jaw 13 by springs 25. By rotating the shaft 14 the top clamping jaw 13 is forced downwardly against the lower jaw 12 and so long as the circular portions 18 of the cam discs engage the slab 20 the springs 25 determine the contact pressure between the jaws and the strip ends 1 and 2. When the cut-away portion 19 of the cam discs engage the slab 20 the latter pivots about its pin 21 and the springs 24 raise the beam 23 together with the top clamping jaw to release the strip ends. The shaft also carries two eccentrics 26 with crank arms 27 connected to a beam 30 which is connected by bolts 31 to a plate 32 underneath the lower clamping jaw 12. The lower plate carries puncturing punches 3 corresponding to holes 36 in the lower clamping jaw. The beam 30 is provided with a corresponding number of turning-over punches 4 corresponding to holes 38 in the top clamping member. The punches 4 are adjustably spring- loaded in the beam 30. In operation when the end of the strip 1 approaches the slot between the clamping jaws the strip end 2 is placed to overlap the end of the strip 1. The shaft 14 is then rotated one revolution during which the clamping jaws securely grip the two strip ends and at the same time the eccentrics 26 cause the lower plate carrying the punches 3 to move upwards and produce holes with burrs 5 and 6 in the overlapping strip ends after which the punches 3 are returned and the turning-over punches 4 strike the burrs and return to their initial position. A flywheel and a clutch (not shown) provided with automatic means for disengagement ensures that the shaft 14 only rotates one revolution at a time.

Title: Improvements in and relating to sighting mechanism for guns and the like
IPC: F41G3/00
Filed: 1946-05-16
Abstract: 653,610. Gun sights. BRITISH THOMSONHOUSTON CO. Ltd. (General Electric Co.). May 16, 1946, No. 14841. [Class 92(ii)] The sighting mechanism for a gun 11, Fig. 7, has its line of sight controlled by a gyroscope 24, Fig. 1, and means are provided for applying processing torques to the gyroscope in accordance with the speed of the target and its range and elevation in order to displace the gyroscope, and hence the line of sight, through the correct angles allowing for lead and gravity drop. The gyroscope casing 15 shown is mounted on a stand 52 turning with the gun on a turntable 12, and is connected with the gun by links 48, 49, the arrangement being such that the casing follows the movements of the gun in training and elevation. The gyroscope is mounted within the casing on a gimbal ring 19 which also carries a mirror 43 through which the target is viewed, the gyroscope and mirror being so interconnected by a link 45 that the line of sight reflected by the mirror from a light source 41 is always parallel to the axis of the gyroscope. The casing 15 houses an eddy current disc 28 on the gyroscope rotor shaft 27, an associated electromagnet 32 with pole pieces 33, 34, and a weight 53 on a pivoted arm 54 for applying a torque to the axis 20 of the frame 19. The leverage of the weight 53 varies with the tilt of casing and hence with the gun elevation, and is so chosen that for all elevations it depresses the gyroscope axis, and hence the line of sight through the mirror 43, through the correct angle. The correct. lead angle for all speeds and ranges of targets is obtained by suitably varying the flux density through magnet 32 by means of a rheostat calibrated according to the range, whereby the correct lag is obtained as the target is followed by'keeping the image of a reticle on a disc 39 in line with the target.

Patent GB-152327-A (GB)
Abstract: 152,327. Etablissements Deesse. Oct. 8, 1919, [Convention date]. Magneto - electric machutes. - A distributor for the secondary current of a high-tension magneto, in which the magnets are fixed and the armature rotates, consists of an independent ring of insulating material co-axial with and rotating at a different speed from the armature and giving a spark in one of any number of cylinders every time the armature leaves the field. A form for four cylinders is shown in vertical and horizontal sections in Figs. 1 and 2, the arrangement of the contacts in the ring being shown in similar sections in Figs. 6 and 6a. The armature shaft 4 drives, by means of a gear wheel 5 and a pinion 6 journaled at d in the end cap and a boss carried thereby, a toothed ring 11 to which the double distributor ring 12 is secured, the ratio being such that the ring rotates at half armature speed. Rigid on the armature shaft is a brush-holder 17, the brush 19 of which receives the secondary current lead at 18 and makes contact with the inner surface of the ring. Integral with the ring are two metal segments, Figs. 6 and 6<a>, each comprising pairs of inner contacts 13, 14 engaged by the brush 19 and outer contacts 15, 16 engaged by the brushes 22, 23, 24, 25 connected to the sparking-plugs. Thus, while the armature makes two revolutions and the distributor one revolution, the brush 19 is connected to the four plugs in sequence. Axial movement of the ring 11 is prevented by studs engaging a groove 26, Fig. 1, or by a retaining ring 27, Fig. 2, in the casing, and oil, which is introduced at 29, is retained by a felt washer 30.
