Title: Improvements in mechanism for converting an oscillating movement into a step-by-steprotational movement, particularly applicable to electric clocks
IPC: G04C13/10
Filed: 1928-01-12
Abstract: 297,891. Smith, S. J. Jan. 12, 1928. Electric clocks.-In pawl and ratchet driving mechanism the engagement and disengagement of the pawls is effected electromagnetically. The armature 15 oscillating between the poles 13, 14 of a magnet 12 is pierced laterally at 23 to receive a wire pawl 24 which drives a fibre ratchet wheel 21 of six teeth. The armature is loose on a shaft 20 which has attached to it the ratchet and also a worm 22 which provides an irreversible drive to the clock hands. A tail piece 26 of the pawl moves near the pole 13. When the armature is attracted the pawl is drawn back and a spring 30 is stressed and near the end of this movement the piece 26 is attracted by the energized pole so that the pawl 24 is drawn into engagement with the ratchet. On the return stroke the spring 30 drives pawl 24 and ratchet 21 and an abutment 43 prevents the pawl leaving the ratchet. The pawl 27 preventing retrograde movement of the ratchet is similarly controlled magnetically. A disc 32 on the shaft 20 permits adjustment of the clock hands. The magnet, pole pieces, and shaft 20 are all mounted as a unit on a frame 18 which is attached to the remainder of the clock by a screw 19. A fibre stop 42 prevents overthrow of the armature.

Abstract: 345,108. Making tubes. SOC. ANON. DES HAUTS-FOURNEAUX ET FONDERIES DE PONT-A-MOUSSON, Pont-- Mousson, Meurthe-et-Moselle, France. March 29, 1930, No. 10084. Convention date, Oct. 11, 1929. [Classes 83 (ii) and 83 (iv).] Bending dies and formers.-In the manufacture of tubes by bending a strip, reversely curved at its centre portion, in dies, the mandrel, that effects the first shaping and around which the strip is closed, is associated with means whereby it may be given initially, a deflection equal and opposite that to which it is subjected during the bending- operation. The flat sheet is first placed with its edges against shoulders 2, 2a on a matrix 1 and is stamped to the form shown in Fig. 6 by the die 3 of an hydraulic press so that the curved portions a, b, c and d, e, f are each more than a quarter of the width of the sheet, and their internal radius is slightly less than that of the finished tube so as to allow for the opening out of the blank due to its elasticity when removed from the matrix. The stamped blank is then placed in the port a<1>, b<1>, e<1>, f <1> of a matrix 4, Figs. 7 and 8, which if formed with a recess m<1> of such radius as to produce a tube of internal radius intermediate between that of the curved portions and that of the finished tube to allow for elasticity. Inclined portions b<1>, h<1> and e<1>, l<1> are provided to facilitate stamping. The stamping is effected by a mandrel 5, connected by pins 9, 9a to stretchers 7 mounted in a carrier 6. The stretchers are first adjusted by nuts 8, 8a so as to deflect the mandrel at the centre against bearings 11, 11a mounted in the carrier, to an extent corresponding to the reverse deflection produced by stamping. The pin 9a and stretcher 7a are removed after stamping and the mandrel dropped on its pivot 9 against a stop 12, whereupon the tube is removed.

Title: Crimpable Conjugate Filaments and Yarns and process for the preparation thereof
IPC: D01F8/12
Filed: 1967-03-07
Abstract: 1,159,875. Crimped conjugate polyamide filaments. ASAHI KASEI KOGYO K.K. 7 March, 1967 [11 March, 1966], No. 10697/67. Heading B5B. Conjugate filaments having crimp potential are formed by simultaneously melt-spinning through the or each hole of a spinneret a homopolyamide and a terpolyamide obtained by copolymerizing # - caprolactam (6M), hexamethylenediammonium adipate (66 salt) and hexamethylenediammonium terephthalate (6T salt) and drawing the resultant filament or yarn. The homopolyamide may be poly-#- caprolactam or polyhexamethylene adipamide. The filaments may be cold-drawn, in which case they do not immediately become crimped when they are relaxed, or may be drawn at a temperature of 60 C. or above, in which case the filaments become crimped as soon as they are relaxed. The crimp may be greatly improved by subjecting the drawn filaments to heat treatment in a relaxed condition or under a load of about 0À5 mg./denier. The heat treatment may be effected at a temperature within the range 60 to 180 C. If hot water or steam is used as the heating medium, a temperature of 80 to 110 C. is preferable. If the melting point of the terpolyamide is not higher than 200 C., a spinning oil containing not more than 20% by weight of moisture is heated to 40 to 80 C. and is applied to the filaments before they are drawn to prevent the filaments from becoming stuck together on the winding bobbin. The composition of the terpolyamide may fall within the area in a diagram of triangular co-ordinates representing the composition of the copolymer defined by a polygon formed by connecting by straight lines five points corresponding to the molar ratios of 6M, 66 salt and 6T salt of 99À8 : 0À1 : 0À1, 0À1 : 99À8 : 0À1, 0À1 : 70 : 29À9, 20 : 40 : 40 and 60 : 0À1 : 39À9, respectively. By using terpolyamides whose composition falls within areas of specified polygons falling within the area of the main polygon defined above one or other desired properties of the filaments may be emphasized.

Title: Improvements in or relating to the production of filaments, yarns, threads and other articles from natural silk
IPC: D01F4/00
Filed: 1930-04-04
Abstract: Albumens and albuminoids, processes for making artificial silk and like textile materials from; albumens and albuminoids, films or sheets containing.-Filaments, threads, yarns, bristles and other articles are formed by dissolving natural silk in an acid, imparting to the solution the desired shape and then subjecting the solution to the action of a precipitating agent comprising one or more alcohols, e.g. ethyl or methyl alcohol.  A strong acid is preferably employed, but not sufficiently strong to impair the silk at the temperature employed.  Sulphuric acid of 25-75 per cent, syrupy orthophosphoric acid and hydrochloric acid are specified.  To prevent deterioration, low temperatures are employed, e.g. from -10 DEG  C. to 10 DEG  C., and are preferably maintained during storage, if any, and precipitation.  The solution is extruded to form light or heavy filaments.  The precipitating bath is preferably of large volume and may include a diluent for the acid and/or neutralizing substances, e.g. sodium, potassium or ammonium hydroxides or acetates.  Yarns produced by the invention may be associated with other yarns, e.g. natural silk, cotton, wool or yarns of cellulose acetate or other organic derivatives of cellulose.  In an example, 8 kg. of degummed natural silk is added to 25 litres of 50 per cent sulphuric acid cooled to about 0 DEG  C., and the cold solution is extruded into a large bath of ethyl alcohol kept at about 0 DEG .  The spun threads may be wound by a cup-spinning device, centrifugal pot, &c. and are thoroughly washed to remove traces of acid either prior or subsequent to winding.  The Specification as open to inspection under Sect. 91 (3) (a) states that the precipitating bath may consist of water or dilute aqueous salt solutions.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in instruments for measuring alternating potentials or alternating currents
IPC: G01R17/16
Filed: 1944-06-05
Abstract: 587,581. Thermionic ammeters and volt meters. MARCONI INSTRUMENTS, Ltd., and BROCKELSBY, C. F. June 5,1944, No. 10800. [Class 37] The invention relates to alternating current or voltage measuring arrangements wherein the quantity to be measured is applied to the control grids of a pair of thermionic valves, the anodes of which are fed with a reference alternating potential of the same frequency, so that the deflection of a D.C. measuring instrument depends on both the magnitude of the quantity being measured and its phase relationship to the reference potential. According to the invention the mutual conductances and the A.C. resistances of the valves are adjustable substantially independently of one another so that the characteristics of the two valves may be made identical. As shown, Fig. 1, the potential E1 to be measured is applied through a transformer T to the grids of triodes V, V1 in anti-phase and the reference potential E2 is fed to both anodes in phase. The mutual conductances of V, V1 are adjusted by variable resistances R1, R1<1>, respectively, and their A.C. resistances by anode resistor R2, R2<1>, in series with further resistors R3, R3<1>, if desired. The value El. cos # is measured by a D.C. instrument G which by initial adjustment of the valve characteristics is arranged to read zero.when E1 is zero, over a range of values of E2, # being the phase angle between E1, E2. For balancing an A.C. bridge network B, Fig. 2, the valves V, V1 are included in one envelope, R1, R1<1> and R2, R2<1> are formed by potentiometers and R3,- R3<1> are omitted. The source M supplies the bridge B and reference voltage E2 in phase therewith by separate transformer secondaries T1, the bridge output E1 being fed to the valve grids through transformer T. The transformer T may be omitted if the grid of one valve is connected to point A, Fig. 1, by way of source E1 and the. grid of the other valve connected directly to A. Also the grids may, alternatively, be energized in phase and the anodes in anti-phase. The meter G may, alternatively, be connected across the anode ends of R2, R2<1>. Specification 385,982 is referred to.
