Title: Stropping or Sharpening Apparatus for Razor Blades and the like.
Inventor: EARLE STANLEY BEAUMONT
IPC: B24D15/08
Filed: 1916-03-02
Abstract: 104,387. Earle, S. B. March 2, 1916. Stropping . apparatus. - In razor stropping and sharpening apparatus wherein rolls 1, are geared together by a gear train 3 - - 6 of the sun-andplanet type, the axis of the sun-wheel 6 being coincident with an axis about which the rolls may be hinged towards and away from each other as the gearwheels remain in mesh, the rolls are provided with non-traversing helical sharpening-portions 1<a>, 2a which bear upon non-opposite parts of the blade edge so as to tend to flex it temporarily to a frilllike edge, and the upper roll 2 is so hinged that (it can be raised from the blade to provide unobstructed access thereto, guiding and positioning means of the steady-pin kind being fitted for fixing the blade in position. The blade may be held out of contact with the lower roll until the upper roll has been closed down thereon, and the device may be fitted at one end of a razor-containing or bladereceiving box in such a manner that, when the upper roll is moved down, the lid 11 of the box, with or without an intervening spring 12, serves to keep the rolls to their work. As shown in Figs. 1 and 3, the box 9 is adapted to hold a complete razor, which rests with its handle 13 upon a seating 19 and its slot 16 in engagement with a V- ended plate 17 provided with positioning-notches 18. A pawl 20 prevents turning of the rolls in the wrong direction by the crank-handle, which, when not required, can be folded inwards to engage with an opening in the side of the box; or the handle may be so connected to its axis that it comes out from engagement therewith if turned in the wrong direction. The spring for exerting the yielding pressure may be carried by the lid. The stropping-apparatus may be duplicated, so that the opposite sides of both cutting-edges of a doubleedged blade may be simultaneously treated. The upper roll may also be carried by the box lid arranged to hinge about the hinging axis of the rolls, the necessary gapping beyond the hinge being closed in by a bellows-like fitting or bv parts arranged to slide over one another as the lid is opened and shut.

IPC: B23K11/00
Filed: 1951-02-10
Abstract: 696,151. Making cycle wheel hubs. PHILLIPS & CO., Ltd., J. A. Feb. 8, 1952 [Feb. 10, 1951], No. 3304/51. Classes 83 (ii) and 83 (iv). Welding.-A method of making cycle wheel hubs and pedals comprises electrically resistance welding the ends of a connecting tube to the spigots of end members located in abutment with the ends of the tube and employing an element of high thermal conductivity in contact with a medial portion of the tube for localizing the welding heat in the region of the abutting faces of the assembled tube and end members. End members 10 of a cycle wheel hub have, a bore 11, a cup-shaped recess 12 for receiving a bearing cup (not shown), and a spoke flange 13 provided with a projecting lip 15. The body of the end member may be conical or other shape having a projecting tubular spigot 18 which abuts the end of a connecting-tube 19. A pedal centre 20 comprises cup-shaped end members 21 each having a spigot 22 which abuts the end of a tubular member 23. The assembled end members and connecting tube are electrically resistance-welded by clamping the medial portion of the connecting tube in a copper clamp 27 of substantial mass and inserting electrodes 29 in the end members. Said clamp, by dispersing the heat of the welding operation, localizes said heat to the abutting faces of the tube and end members, thus preventing distortion of the tube. Each electrode is a close fit in the end member and each has a projection 30 for entering the spigot of the end member, said projection terminating a short distance from the abutting faces of the tube and end member.

Abstract: 212,707. Livesey, T., and Moore, F. D. Feb. 3, 1923. Patent surfaces.-In a machine for removing the pegs or pins from the pattern lags of dobbies, the lag chain comprising lags 37, Figs. 9 and 10. and connecting links 38 and staples 39 is passed over an intermittently-rotated grooved roller 40 and a reciprocating punching-bar 29 provided with steel punches 35 descends, so that the punches eject the pattern pegs &c. 43 that may be present in any of the holes 36 in the lags, these ejected pegs &c. entering the grooves 42 in the roller. The descending bar 29 acts on the curved parts 76 of wings or brackets 77 on bars or holding-jaws 70, thereby turning these jaws about shafts or trunnions 69, against the action of springs 84, into the position shown in Fig. 10, and causing lips or projections 71 to engage the inclined edges of the lag to be operated upon and thus position it accurately below the punches. The turning of the jaws may be assisted by means of levers 90 adapted to engage the edges 92 of the holding-jaws. As the punching-bar ascends, it operates a tappet lever connected to lever and ratchet mechanism for operating a ratchet-wheel on the shaft &c. of the roller 40, whereby a fresh lag is brought into operative position beneath the punches. A spring-controlled lever acts on a setting plate furnished with a number of flat surfaces corresponding to the number of grooves 42, whereby the roller 40 is retained in correct position after it has been turned. Lags of slightly varying length are centralized as they come into operative position on the cylinder 40 by means of levers 96, Fig. 12, having forward reversed ends 98 tapered at 106 and connected by links 99 to a spring-controlled lever 100. The punching-bar is reciprocated from eccentrics on a shaft driven from a shaft carrying a flywheel and diving- pulley and furnished with a clutch orerated from a pedal.

Title: Improvements in or relating to the amplification of signals in the reception of quadruplex telegraphy
IPC: H04L5/04
Filed: 1928-11-02
Abstract: 324,678. Creed & Co., Ltd., WiUson, E. A,, Woodman, K. F., and Greig, E. Nov. 2, 1928. Quadruplex telegraphs.-In a quadruplex telegraph receiver, thermionic valves are used to differentiate between A signals, which change in polarity, and B signals, which change in amplitude. Potentials developed across resistances r', r, connected to an ordinary bridge circuit 0, are applied differentially to a pair of similar amplifying valves 2, 22. To resolve A signals the adjustable contact of a potentiometer auxiliary anode resistance p<2> is connected through a coupling battery b<3> to the grid of a valve 3, the mean grid potential of which is so adjusted that negative A signals reduce the grid potential to the bottom bend of the characteristic curve and the valve does not respond to the greater amplitude set up by B signals. A similar cut-off of positive signals is obtained at the top bend of the same valve or at the bottom bend of a succeeding valve 4. A marking coil Am of a polarized relay and a spacing coil As are inserted in the plate circuit of further amplifying-valves 4, 5. To resolve B signals, the valves 2, 22 are coupled through potentiometers p<2> p<22> and batteries b<6>, b<7> to a parallel pair of valves 6, 66, the grid bias of which is so adjusted that the highest potential due to A signals lies on, or to the left of, the bottom bend of the characteristic and the valves respond to B signals only. The spacing coil Bs of a non- polarised relay is connected in the anode circuit of a valve 7 coupled to the parallel valves by a resistance r<6> and the marking coil B<m> is in the anode circuit of a succeeding valve 8. To bridge over gaps in long B signals due to the less amplitude produced during changes in polarity caused by simultaneous A signals; a phase-splitting condenser c<x> is connected in shunt with the winding B<m>.

Title: New preparations with adrenocorticotropic hormone activity and the manufacture thereof
IPC: C07K14/695
Filed: 1964-01-27
Abstract: Compounds having a prolonged adrenocorticotropic hormonal activity consist of a sparingly soluble complex of a pharmaceutically suitable salt, hydroxide or oxide of a metal retarding the resorption of protein hormones and a peptide, having adrenal cortex stimulating activity, consisting of the amino-acid sequence of at least the first 19 and not more than the first 31 amine acid residues from the N-terminal end of an ACTH molecule as obtained from mammals. Suitable metals are Zu; Cu; Ni; Co; and Fe; and they are used in quantities of 1 to 20 mgs. of metal per 100 U.S.P. units of peptide. Preferred salts are phosphate, chloride, acetate and sulphate. Particular peptides mentioned are synthetic 19, 20, and 24 amino-acid residue peptides and 26 and 31 residue peptides prepared by enzymic degradation of a natural mammalian ACTH molecule.  The term "peptide" includes functional derivatives thereof, such as amides, hydrazides, esters, and acid or alkali addition salts.  Also, the invention relates to injectable compositions of the complexes suspended in an aqueous injectable vehicle; such compositions have a pH of 6.0 to 8.0, and preferably also contain a preservative, such as a phenol benzyl alcohol, or a p-hydroxy benzoic acid ester; a solute such as sodium chloride to make the solution isotonic with body fluids; a buffer, and a phosphorus oxy-acid, or its salt, or a derivative of such an acid (e.g. nucleoside phosphate; phosphoserine; or creatine phosphate), which substances have stabilizing properties.  The complex may either be used in suspension, if a sparingly soluble metal salt is employed, or may, if a soluble salt is used, be in the form of a solution.  The complexes are prepared by mixing aqueous solutions or suspensions of the salt, oxide or hydroxide, and the hormone.  The injectible preparation may also take the form of an aqueous solution of salt and protein outside the stated pH range of 6.0 to 8.0 (e.g. pH 4.0) which, on injection, forms the sparingly soluble complex at the pH of the tissue fluids.

Abstract: 558,001. Pigments; rubber compositions. MARINE MAGNESIUM PRODUCTS CORPORATION. March 17, 1942, No. 3552. Convention date, Dec. 31, 1941. Drawings to Specification. [Class 95] [Also in Group V] A filler or pigment, which can be readily milled into oils, paints and rubber mixes, is prepared by forming a slurry containing amorphous carbon and calcium hydroxide and then carbonating the slurry to form particles of calcium carbonate to which particles of finely divided amorphous carbon are intimately attached. The slurry may be formed by slaking the residue obtained by reacting calcium carbide with magnesium oxide at an elevated temperature. In this case, the product of carbonation would contain magnesium carbonate also. which latter could be converted into basic magnesium carbonate, by heating the slurry. If small amounts of calcium sulphate, sulphuric acid, cane or beet sugar, lactose or sodium hexametaphosphate are present during carbonation, or if carbonation is carried out at relative low temperatures, e.g. 5‹-15‹C., the precipitated calcium carbonate has a small particle size, e.g. less than 0.1 micron in diameter.
