Title: Improvements in lapping or polishing machines
IPC: B24B5/42
Filed: 1930-09-22
Abstract: 361,488. Operating clutches. NORTON CO., New Bond Street, Worcester, Massachusetts, U.S.A. Sept. 22, 1930, No. 28327. Convention date, Sept. 20, 1929. [Class 80 (ii).] In a machine for lapping an article such as a crank shaft or the like, the article is rotated in a support and means are provided in connection with the driving mechanism for stopping the lapping operation after a predetermined number of revolutions of the work. The loose wheels 70, 71 of a twospeed gear may be clutched alternatively to the driven shaft 55, Fig. 4, by means of a clutch 72 operated by a yoke 75, which is moved into neutral position to stop the rotation of the work after a predetermined number of revolutions thereof. A frame 96, Fig. 9, rotatable about the axis of a shaft 91, carries two gears 92, 93, Fig. 4, both meshing with a pinion 90 on the shaft 55, rocking movement of the frame by means of a handle causing either gear to drive a gear 99 rotatable in the headstock. An eccentric 103 on the gear 99 reciprocates a connecting-rod 104 which carries a pawl 105 engaging a ratchet 107. A cam 109 secured to the ratchet coacts with a lever 110 on a shaft 111 carrying a detent 83 for a lever 82 attached to the clutchoperating shaft 79, the action being such that after a predetermined number of revolutions of the work the cam 109 rocks the shaft 111 and withdraws the detent from the lever 82, thereby allowing one of the springs 85 to move the clutch 72 into neutral position. Rocking of the frame 96 changes the speed of rotation of the gear 99, and the number of rotations allowed to the work before stoppage may be further varied by means of a shroud 114 on the ratchet 107, controlled by a handle 116 and a graduated scale 117. A lever 80 provides for actuating the clutch 72 by hand and a handle 113 for releasing the detent 83.

Title: Frequency setting fork
IPC: H03B5/30
Filed: 1929-09-18
Abstract: 339,994. Electrical Research Products, Inc., (Assignees of Curtis, A. M.). Oct. 4, 1928, [Convention date]. By varying resistance.-In electric ally-operated frequency setting devices of the tuning fork type a valve amplifier is controlled by a tuning fork having pick-up and drive coils characterized in that polarizing windings associated with the coils are supplied from the same source of potential as the anode of the valve. In the circuit shown the tuning fork 10 has a pickup coil 11 connected to the input of valve 12 through the transformer 50. The secondary winding of the transformer 14, the primary of which is connected in the output circuit of valve 12, is divided, a part 15 being connected through a resistance 16 and condenser 33 to the drive coil 13, and a part 17 being connected through a filter circuit 18 and transformer 19 to the amplifying valves 20, 21. The filament and anode currents are drawn from the same source 24, the filament circuit including resistances 26, 27 so that the drop of potential across the resistance 27 provides a negative bias on the grids of the valves. The drive and pick-up coils are provided with polarizing windings 35, 36 connected in series and supplied from source 24 through variable resistances 38, 38<1> and choke coil 37. By a suitable adjustment of the normal current through this polarizing winding the arrangement can be made to compensate for variations in the amplifier efficiency caused by variations in the supply voltage at 24. Magnetic coupling between the drive and pick-up coils is reduced by arranging the coils so that the flux traverses the fork tines in a transverse direction. When the fork is not of magnetic material shoes 5 of magnetic material are mounted on the tines in a manner to avoid damping of the fork. The Specification gives the composition of a steel the elasticity of which changes little with temperature variations.

Abstract: 243,023. Akt.-Ges. f³r Anilin-Fabrikation. Nov. 14, 1924, [Convention date]. Reproducing opaque originals by contact Printing; photo-mechanical printing -surfaces ; bichromated colloid and like processes; sensitized films; developing; retouching. - In preparing printing surfaces and preliminary copies by the " reflection " process in which the sensitized material is exposed in contact with an original to light passing through the sensitized layer, the treatment which follows the exposure is such that the picture is formed on the layer instead of within the layer. The thickness of the sensitive layer may be varied within wide limits. As colloids gelatin, gum arabic, sugar or the like may be used, and as sensitizing agents chromates, iron salts, uranium salts, &c. Alternatively, silver halide emulsions may be used and developed by physical means, e.g. by selective deposition of metal or a metallic compound from supersaturated solutions. Alternatively, intensification by such physical methods may follow chemical development. A printing surface may be directly obtained from a colloid layer sensitized with bichromate which may also contain a catalyst such as a salt of copper or manganese. After exposure, washing, drying and moistening with glycerine and water, prints may be obtained with a fatty ink as in collotype printing. Prints may be made on zinc, reversed, and used for offset printing; or prints may be made on lithotransfer paper for making zinc plates for direct printing. A bichromated colloid layer may be treated for use as a negative by inking the exposed layer with a fatty ink, moistening and drying it, and then sprinkling with bronze powder. It may then be thinly coated with lacquer and retouched as necessary. Reproductions may be made by spraying on exposed hygroscopic colloid layer with fine powder after exposure and moistening. Alternatively an exposed colloid layer soluble in water, or which swells in water, mav be inked with fatty ink and then developed with water which may contain also an agent that promotes development, such as lactic acid or acetic acid. Specification 6275/08 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes the use of an anticurling coating on the back of the negative film or a layer which could be used for re-touching. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the production of titanium pigments
IPC: C01G23/00
Filed: 1933-10-20
Abstract: Zinc orthotitanate or pigments containing it are prepared by calcining at temperatures not exceeding 800 DEG  C. a mixture of an oxidic or hydratic compound of titanium associated if desired with extenders and a compound of zinc such as the oxide, the titanium and zinc being present in the proportions of 1 : 2 reckoned as TiO2 and ZnO.  When hydrated titanium oxide is employed, it may be treated, prior to calcination, to remove sulphuric acid therefrom, such removal being effected before or after admixture with the zinc compound, and in the case of composite pigments, before or after admixture with an extender.  In using a hydrated titanium compound, the mixture may be dried, say at 75 DEG  C., prior to calcining, and in the calcination step, the presence of a small amount of a halogen compound, for instance, hydrochloric acid promotes the reaction.  A relatively small amount of a salt such as sodium or potassium sulphate or sodium carbonate, or of phosphoric acid or a phosphate such as calcium or barium phosphate, may also be added to the mixture.  Extenders referred to are barytes, blancfixe, gypsum, whiting, silica, clay, and asbestine, and the use in the process of a composite pigment containing 75 per cent of barium sulphate and 25 per cent of titanium oxide is specified.  Specifications 347,129 and 384,473 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the following subject - matter:--No limitation as to the relative proportions of titanium and zinc in the reacting mixture is imposed.  Temperatures of 650-11000 DEG  C. may be used, and the use of zinc sulphide, lithopone, and zinc sulphate is referred to. Examples are also given of the calcination of mixtures of zinc oxide with composite pigments containing titanium oxide and barium or calcium sulphate.

Abstract: 453,385. Stapling. POLZER, F., South Norwalk, Connecticut, U.S.A. Oct. 23, 1935, Nos. 29272 and 29273. Convention dates, April 25 and June 8. [Class 89 (iii)] In a machine for stapling or tacking, which may be of the desk or pliers type, comprising a reciprocable driver 14 and a guide bar 20 along which a strip of staples 21 is fed by a pusher 22 and spring 23, the front wall of the driver passage is arranged to be yieldable, so that staples of different thicknesses can be driven. As shown, the base 10 of the machine is slotted at 10a so that it can be turned back when the machine is to be used as a tacker. The yielding wall of the driver passage is constituted by a U-shaped spring member 25, Fig. 9, which is supported on a pin 27 in a hollow block 33. The latter is secured detachably to the housing 12 by means of a screw 31 and a lug 20d on the guide bar 20. The wall 26 of the member 25 normally is spaced from the front of the guide bar 20 a distance equal to the thickness of the thinnest staple to be used. If thicker staples are used, the wall 26 yields to accommodate them. The top front edge of the bar 20 is bevelled as at 34, Fig. 4, to facilitate the entrance of thick staples into the driver passage and to assist in straightening staples whose cross-bars are not properly positioned perpendicularly to the axis of the bar 20. Curved recesses 38 formed in the wall 26 of the member 25 act to straighten staples which enter the driver passage with their legs tilted forwardly. Staples with legs tilted backwardly are accommodated by recesses 20b in the bar 20, and are straightened by curved shoulders 20c on the bar. In modifications, the recesses 38 are omitted from the wall 26, and the front wall of the block 33 is omitted. In another modification, the yieldable wall is formed as a pivoted plate spring-pressed towards the bar 20. In another modification, the yieldable wall is formed as a block 82, Fig. 14, which is pivoted on a pin 81 in a removable part of the housing and is pressed towards the guide bar 62 by a spring 90. The block 82 is formed with recesses 98 for straightening a forwardlytilted staple, and supports a pivoted dog 88 which acts to prevent a second staple from entering the driver passage until the preceding one has been driven therefrom. Specifications 411,545, 453,383, and 453,384 are referred to.
