Title: Improvements in or relating to folding and collecting mechanisms
IPC: B41F13/54
Filed: 1932-04-15
Abstract: 385,173. Paper folding and associating apparatus. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Goss Printing Press Co. ; 1535, South Paulina Street, Chicago, U.S.A.) April 15, 1932, No. 10891. [Classes 100 (i) and 100 (ii).] In a rotary folding and associating apparatus for printing-presses, the collecting cylinder 21 transfers the sheets directly to the folding cylinder 20 and has an odd number of sets of sheet-impaling pins 42 which are operated by a cam at intervals of more than one revolution. As shown, the collecting cylinder 21 has three sets of impaling pins 42 and the folding cylinder 20 has two folding blades 24 with corresponding impaling pins 28, coacting cutters 30, 40 being provided on the cylinders as usual. The pins 42 are carried by levers 45 operated by a grooved cam 48 driven by similar gears 60, 61 from the folding cylinder so that it has a rotary speed of three to two relatively to the collecting cylinder 21 and thus operates the pins 42 every other revolution to withdraw them from the sheets carried thereby for transfer to the pins 28 on the cylinder 20 which at that moment have engaged the leading edges of the succeeding sheets, the associated sheets subsequently being folded. For such collecting operation it is necessary that one set of pins 28 should be rendered inoperative and for this purpose the operating arm 32 thereof, which carries a roller 33 running in a fixed grooved cam 35 as usual, is fixed to its spindle 31 by a bolt- and-slot connection which can be released so that the arm can move freely without operating the pins 28. If it is desired to obtain non- collected products, the gear 60 is slid axially out of engagement with the gear 61 and the cam 48 is fixed by a set-screw 67 to the shaft of the collecting cylinder 21 with the pins 42 held inoperative, so that the cylinder 21 becomes a cutting cylinder only, both sets of pins 28 being operative. Guides 76 are provided to ensure retention of the sheets on the cylinder. Means are provided for adjusting the fixed cam 35 operating the pins 28 and comprises an arm 39 fixed to the cam and having a slot 38 engaged by a bolt 37 so that the arm can be locked in the desired position. One of the folding-off rollers 74 is mounted in eccentric bearings so that the spacing of the folding-off rollers may be adjusted. Two sets of apparatus may be mounted side by side with suitable guide rollers provided for leading either set of webs to the folder of the other set if desired.

Title: Improvements in or relating to the formation of chemical conversion coatings upon metal surfaces
IPC: C23C22/10
Filed: 1963-03-21
Abstract: Iron and steel surfaces are phosphated with aqueous acidic alkali metal (to include ammonium mono-hydrogen- and ammonium di-hydrogen-) phosphate solutions containing nitrite ion (NO2-) and a heterocyclic compound, and when the heterocyclic compound concentration ranges 0.05-1.0 gm./litre then the nitrite ion concentration = 0.05-1.0/molecular weight of heterocyclic compound X 46 gms./litre and when the heterocyclic compound exceeds 1.0 gm./litre the nitrite ion concentration ranges from 0.05/molecular weight of heterocyclic compound X 46 to 10.0 gms./litre.  The pH=4.0-5.8, preferably 4.5-5.7.  The temperature is at least 120  DEG F. (49  DEG C.), the operating range being 120-150  DEG F. (49-66  DEG C.) and preferably 130-145  DEG F. (57-63  DEG C.).  The heterocyclic compounds comprise melamine, 3-amino-1,2,4-triazole, imidazole, succinimide, 2-oxazolidone. Coating varies between 30 seconds and 5 minutes, preferably 1-3 minutes.  Concentration of the nitrite ion varies directly with respect to concentration of the heterocyclic compound up to 1.0 gm./litre of the latter as prescribed by the above formula. For heterocyclic compound contents in excess of 1.0 gm./litre the nitrite ion concentration may rise to a miximum of 10 gms./litre.  30 gms./litre or more of heterocyclic compound may be used as determined only by solubility considerations but in practice quantities are limited to 10.0 gms./litre. The nitrite ion may be introduced as a salt of alkali or alkaline earth metals, preferably NaNO2.  Although at least 0.05 gm./litre of heterocyclic compound must be incorporated in the solution, it is preferred to use 0.1 gm./litre of the heterocyclic compound as the practical minimum concentration due to drag-out losses. A wetting agent may be incorporated.

Title: Improvements in telephone receivers and like instruments
IPC: H04R9/06
Filed: 1922-04-24
Abstract: 178,862. Farrand, C. L., and Davis, W. H. April 23, 1921, [Convention date]. Magnetic instruments; thermionic relays and repeaters.-The large conical diaphragm D of a telephone receiver is supported by arms e radiating from a central structure. The circumferential flange of the diaphragm is held between clamping-rings b, c, the arms e being attached to or integral with the rings c. In the form shown in Fig. 1, the arms e carry a tube f through which extends a rod g attached to the diaphragm at its apex. At the free end of the rod g is a rocking member h, secured to which is the armature j. In the form shown in Fig. 2, the arms e carry a yoke member p, the core q of which is surrounded by a coil W. The front of the yoke member p is closed by a circular pole member s leaving a small gap around the core q in which is disposed a coil M. This coil is secured by a spider u and a rod v to the apex of the diaphragm D. A polarizing-current is passed through the coil W<1>. The electromagnetic system may be multiplied and spaced round the outer edge of the diaphragm. The ring c carries a pin which fits into an aperture in a portable base member. The Specification as open to inspection under Sect. 91 (3) (a) states that the apparatus may be used for recording on or reproducing from a gramophone record. A method is described by which the variations of current in coil M due to vibration of the diaphragm D by speech may be amplified by means of thermionic valves A, A<1>. A<2>, Fig. 3 (Cancelled), and the coil M' of a similar instrument may be connected in the anode circuits of the valves for receiving. The batteries 7, 11, 13 impress such a potential on the grids that each valve operates on the straight part of its characteristic curve. Either or both of the diaphragms D, D', may be connected to the recording or reproducing stylus of a gramophone. The two instruments may be in the same room or may be connected by conductors, and thermionic-valve amplifiers may be used at either or both stations. In transmitting radio telephony or telegraphy, Fig. 8 (Cancelled), the variations of potential due to currents in coil M are amplified by the valve A and impressed on the grid of a modulating valve C the anode of which is connected to the anode of an oscillating valve V. In receiving, the coil M is connected in the anode circuit of thermionic-valve amplifiers. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in fountain pens
IPC: B43K5/18
Filed: 1956-04-18
Abstract: 795,902. Reservoir pens. KOVACS, T. April 18, 1956 [April 18, 1955], No. 11758/56. Class 146(3) A fountain pen having an overflow chamber situated in the front part of the barrel consists of at least one longitudinally extending capillary intermediate space of annular cross section contracting towards the ink reservoir and communicating at the front with the atmosphere and at the rear through an air-passage with the ink reservoir, the surfaces of the bodies forming the capillary, intermediate space or spaces being divided into longitudinal lands by longitudinal grooves formed therein, the grooves having a lower capillary potential with the intermediate spaces. The front part of the barrel 1 is constricted at its front end 2 and a hollow stem 3 inserted. The stem 3 surrounds a feed bar 17 and nib 19 and is itself surrounded by a sleeve 9, thus defining capillary spaces 13, 16 which form an overflow chamber. The hollow stem 3 has a longitudinally hyperboloid surface 8 narrowing towards the ink reservoir, and the sleeve 9 also has a longitudinally hyperboloid surface 15 narrowing towards the ink reservoir. Between the rear ends of the barrel 1, sleeve 9, and stem 3 narrow annular spaces as 12 are formed and these communicate via coaxial bores 35, 36, 37 with a bore 34 leading to the ink reservoir. At the rear end portions of the stem 3 and sleeve 9 narrow slots 27, 28 are provided which, when wet, prevent the passage of air. The intermediate space 16 is arranged to narrow slightly in cross-section towards the nib side of the barrel. Longitudinal grooves 25 and 26 are provided in the stem 3 and sleeve 9 respectively. An air admission passage 21 is provided at the front of the feed bar which communicates, via a bore 22 and bore 23 with the space 13 and via three bores 24, equally spaced around the circumference of the sleeve 9, with the space 16. In operation, during writing, ink flows from the ink reservoir through conduit 20 to the nib 19, replacement air flowing through the passage 21, the overflow chamber, and an air passage 29 into the ink reservoir. Any excess ink flows from the ink reservoir via the slots 27, 28 and the passage 29 into the overflow chamber. During further writing ink is drawn from the ink reservoir via the conduit 20, the reduced pressure thus created in the reservoir causing excess ink to be drawn back from the overflow chamber. The grooves 25 and 26, having a lower capillary potential than the spaces 13, 16 ensure complete filling of the overflow chamber, if necessary, due to the fact that air can escape through the grooves not covered with ink. The longitudinal profiling of the spaces 13, 16 is designed to eliminate non-uniform capillary potential in the spaces and the outer space 16 possesses a higher capillary potential than the space 13 so that the spaces will fill and empty in sequence. Reference has been directed by the Comptroller to Specification 732,982.

The G4 electrode 39 is cylindrical with polished edges which surround adjacent portions of the associated G3 and G5 electrodes 34 and 40, the electrodes G3-G5 constituting a low focus voltage unipotential lens. Assembling electron guns.-The lowermost electrode 31 with its associated cathode is loaded into a support segment 71 which is generally rectangular with a curved edge adapted to receive the electrode; a space 77 is placed above the electrode and the other electrodes and spacers are stacked above to complete a gun assembly 93 with an associated alignment rod 68 passing through all the electrode supports and spacers. In the case of a triple gun in a colour television tube, these assemblies 93 are mounted in a holder 95 so that the electrodes are positioned against a central support post 99 and a cap 101 is placed over the rods 68 and 99. Studs 45 extending from each electrode are secured to support rods (not shown), and the cap 101 is removed to allow the support segments and spacers to be removed and the support post 99 to be withdrawn. In Fig. 4 the post 99 is conical, but if the guns are to be parallel the post may be cylindrical (Fig. 9, not shown), or if the guns are to be asymmetrical the post 99 is also asymmetrical (Figs. 10 and 11, not shown). The post may have a cross-section which is triangular (Fig. 12, not shown) or fluted (Fig. 13, not shown).
