Title: Improvements in or relating to fastener-inserting machines
IPC: A43D95/28
Filed: 1929-09-19
Abstract: 342,788. Inserting fastenings in boots and shoes. BRITISH UNITED SHOE MACHINERY CO., Ltd., KEALL, F. B., and JEAVONS, C. F. R., Union Works, Belgrave Road, Leicester. Sept. 19, 1929, No. 28393/29 and 12960/30. [Class 89 (iii).] A machine for successively inserting loose fasteners in shoe parts, particularly for attaching rubber heel lifts or metal tips to heels, has its cams so organized that the machine stops, after each insertion, with the work support somewhat lowered, and with the driver down and projecting slightly below the footplate. This allows the operator to shift the work by hand ready for the next fastener insertion, and to use the driver as a locating tool for positioning the work correctly. The cams employed in a machine of the kind described in Specification 1494/93, [Class 89, Nails &c.], are illustrated, Fig. 1, not shown, as so organized to produce relative movements of the driver, work-support, separator, and brake as indicated by the lines A, B. C, D, Fig. 4. For attaching metal tips to heels, which tips may require to be forced into close engagement with the shaped top lift before a fastener is inserted, the machine is provided with a lever, which engages the heel breast and forces the heel and tip rearwardly against an abutment before the fastener-insertion. As shown, Fig. 5, the upper part 26 of the horn post is vertically movable with respect to the poweroperated shaft 30. To its lower end is pivoted a link 36 which, in turn, is pivoted to one end of a centrally pivoted lever 40, the other end of which surrounds a rod 46 which is connected to a treadle. When the rod 46 is first lowered, the horn portion 26 is raised yieldingly through a spring 50 to press a heel 62 against the foot-plate 24 of the machine. The upper end of the rod 46 carries a roll 66 and is pivoted by short links 68 to links 54 which carry pivotally a lever 58 having an end plate 60 adapted to engage the heel breast. When the rod 46 is further lowered, the roll 66 swings the lever 58, forcing the heel 62 with its tip 80 against an edge gauge 72 fitted on the foot-plate 24. For heels of varying sizes, the position of the links 54 is adjustable by means of a screw 76. As shown, the under surface of the plate 24 is inclined, so that the fasteners are driven at a small angle towards the middle of the heel. Fig. 5 shows also the position of the driver 20 when used as a work-locating tool. The plate 24 preferably is cut away at its forward edge so that the driver is readily visible.

Title: Improvements in control and ignition systems for fuel burning apparatus
IPC: F23N5/10
Filed: 1948-11-02
Abstract: 655,745. Controlling and igniting burners. ROBERTSHAW - FULTON CONTROLS CO. Nov. 2, 1948, No. 28463. [Classes 75(i) and 75(iii)] A control and ignition system for fluid fuel burning apparatus, including, e.g., a main burner 12 and a. pilot burner 14, comprises a thermocouple 46 adapted in response to the presence or absence of flame at the burner to energize and de-energize, respectively, electromagnetic means comprising an electromagnet 42 and an armature 40, adapted when so energized to hold open a fuel supply valve 34 but incapable of moving the latter to its open position against the bias of a spring 41, manually operable means for resetting the electromagnetic means and a switch controlling the energization of an electric igniter, said switch being so associated with the said reset means as to be closed to energize said igniter during the resetting operation. The reset means may comprise a stem 48 having an operating head 64, which supports the contacts 71 of a switch controlling the electric supply to an igniter 52 and operable by a spring loaded push button 72. To ignite the apparatus a shut-off cock 18 is opened to allow fuel to pass to the pilot burner 14. The push button 72 is then pressed to energize the igniter 52 whilst at the same time the head 64 is moved to seat the armature 40 against the electromagnet 42. The valve member 34 is unseated but the passage of fuel to the main burner 12 is prevented by the closing of the lower end of the valve passage 32 by a further valve member 50 carried by the stem 48. When fuel flowing from the pilot burner 14 has been ignited and has heated the thermocouple 46 to energize the electromagnet 42 sufficiently to retain the armature 40, the push button 72 is released, and the head 64 is moved downwardly by a spring 66, together with the stem 48 and the valve member 50 so that fuel flows to the main burner 12. Should the pilot flame become extinguished the thermocouple 46 will cool to de-energize the electromagnetic means and cut off the fuel supply to the main burner 12. In a modified construction one of the contacts of the switch controlling the electric igniter is carried by the operating head 64 whilst the other is fixed on the casing of the reset means.

Title: Method of utilising spent sulphite lye
IPC: D21C11/00
Filed: 1949-11-07
Abstract: In a process for utilizing waste sulphite lyes by precipitation of the organic mass contained in the same, the waste lye obtained in the production of cellulose from wood and/or other vegetable substances by the sulphite cooking process, optionally after fermentation of the sugar contained in the waste lye, or residual liquid from the distillation column of a sulphite spirit factory, is treated at a temperature above or of 100 DEG  C. with ammonia (NH3) under pressure and is subsequently acidified with mineral acids or sulphur dioxide to obtain an organic mass which can be converted economically into industrially employable products.  The process may be carried out cyclically by separating the calcium sulphite from the lye after the treatment with ammonia, acidifying the remaining solution with mineral acids and collecting the sulphur dioxide evolved, filtering the organic mass, regenerating ammonia from the ammonium salts contained in the filtrate, e.g. with the aid of lime for reuse and utilizing the calcium sulphite and sulphur dioxide in the production of initial sulphite lye.  If ammonium acid sulphite solution is employed in the decomposition of wood or other vegetable material the waste lyes are treated with ammonia and acidified with sulphurous acid in addition to the organic mass which is filtered off, a filtrate containing ammonium sulphite, available for use in the decomposition of wood or similar vegetable material, is obtained. The organic masses may be further treated to obtain soluble alkali lignin or condensation products which may be used in vanillin production or for combustion purposes.  In examples: (1) waste sulphite lye is degasified and treated with ammonia under pressure at elevated temperature and after again degasifying and settling of the calcium sulphite the organic mass is precipitated with gaseous sulphur dioxide; (2) the residual liquid from the distillation column of a sulphite spirit factory and/or thickened spent lye is similarly treated; (3) fermented waste lye is similarly created, alcohol being distilled off with simultaneous removal of ammonia on the column.

Title: Improvements in or relating to toothed gearing
IPC: F16H55/08
Filed: 1919-11-18
Abstract: 163,066. Jones, L. Nov. 18, 1919. Pinions; racks; chain-wheels.-The tooth crowns of a pinion gearing internally or externally with a roller toothed wheel, for instance such as is described in Specification 19772/14, are generated by using the first part of a curve produced by rolling one of the annular or other wheel rollers G with its centre on the pitch circle pc<1> of the wheel, the teeth being thus formed on a pinion of which the pitch circle pc<4> is tangential to the roller at the pitch point, the pinion then being moved to occupy the position pc<2> tangential to the pitch circle of the wheel. The points of the teeth are cut away as shown and the roots are rounded. The annular wheel contains oil centrifugally circulated as described in the abovementioned Specification. The invention may be applied to pinions gearing with roller toothed racks, and to chain-wheels engaging roller chains, in which case the teeth are designed on the assumption that the chain may be considered as a wheel with its pitch circle coincident with that of the sprocket wheel, and in order to maintain such coincidence, additional rollers on the chain pins run on a circular track on the wheel.

Title: Measuring arrangement for electric potentials
IPC: G01R19/22
Filed: 1929-09-20
Abstract: 319,368. Huydts, L. H. M. Sept. 21, 1928, [Convention date]. Pressure Meters; resistances, measuring. - Alternating or direct potentials, and resistances, are measured by means of an instrument containing a diode 3, a filter formed of resistances 9, 10, 11 and condensers 13, 14, 15, a triode 4, and a direct current measuring instrument 18. Alternating potential to be measured is applied to terminals 1, 2, any direct potential present being blocked by a condenser 12. Rectification is effected by the diode 3 shunted by a resistance 8. The alternating potential which is also present is filtered out by means of the resistances 9, 10, 11 and condensers 13, 14, 15, the rectified potential being applied to the grid 21 of the triode 4 and measured by measuring the anode current flowing in the instrument 18. A direct potential to be measured is applied to the terminals 19, 20, the diode 3 being disconnected. Any alternating components present are filtered out by the filter 9, 10, 11, 13, 14, 15. The scale of the instrument 18 for direct and alternating potentials differs by the factor V2. For measuring high voltages the resistance 8 is tapped for use as a potentiometer. Resistances to be measured are connected across terminals 23, 24 in series with a battery 25.

Title: Improvements in throttling and pressure regulating valves
IPC: G05D16/10
Filed: 1945-10-30
Abstract: 603,812. Pressure-regulating valves. BENDIX AVIATION CORPORATION. Oct. 30, 1945, No. 28787. Convention date, Nov. 16, 1944. [Class 135] A pressure-regulating valve to control either positive or negative fluid pressure, e.g. for maintaining a constant air pressure in an aircraft fuel tank or operating a turn and bank indicator, comprises in one form for controlling positive pressure a housing 11, Fig. 3, provided at one end with a wall 12 having holes 30, Fig. 4, open to the atmosphere and a fitting 13 for connection to a source of pressure and whose other open end is closed by a collar 16 formed on a member 15 having conduits 21, 22 separated by a partition 15a which communicate with the pressure source and the instrument to be operated respectively. A valve member 26 slidable on the member 15 is formed with a piston 27 urged towards the collar 16 by a spring 31 and provided with a recess 28 which forms a communicating passage between the conduits through ports 24, 25, and a passage 23 is provided to connect the conduit 22 with the outer face of the piston. In operation, air under pressure passes through the conduit 21, ports 24, 25 and the conduit 22 and also through the passage 23 to the piston to oppose the spring pressure which, when exceeded, allows the piston to move to throttle the ports 25 and regulate the pressure to the operated instrument. In a modification for use with negative pressure, the passage 23 is dispensed with and the valve member 26 is replaced by a modified member 56, Fig. 7, which is reversed in the housing and provided with ports 62 in its periphery to establish communication between the conduits via the chamber 59. In this arrangement, the pressure source is replaced by a suction source and should the pressure operating the instrument become too low, i.e. the suction become too great, atmospheric air will enter the holes 61 to move the member 56 against the spring to adjust the amount of opening of the ports 55 in the conduit connected to the operated instrument.

Abstract: 378,259. Hot blast stoves ; returning combustion products to furnaces. NAAMLOOZE VENNOOTSCHAP NIEUWE OCTROOI MAATSCHAPPIJ, 30, Carel van Bylandtlaan, The Hague.- (Assignees of Blanckenburg, E.; 136, Liberty Street, New York, U.S.A.) Oct. 16, 1931, No. 28824. Convention date, Oct. 17, 1930. [Classes 51(i) and 51 (ii).] In a hot blast stove system adapted to supply heated combustible gas for use in the cracking of oils, products of combustion from a stove which is being heated are passed through each stove at the end of the heating period to purge the stove of air. The stoves may also be purged of combustible gas at the end of the blast period and combustion products may be returned to reduce the temperature during the heating period. Each gas heating stove 10 is provided with a burner 13, a vertically extending combustion chamber 15 and checkerwork 17 communicating through a collecting flue 19 and duct 25 with the chimney 23. The waste gas ducts 25 of a set of stoves are connected by pipes 43 having valves 44 with a pipe 42 so that the waste gases may be withdrawn from any stove and forced by a fan 54 through pipes 45, 49 to the combustion chamber and burner of any stove through pipes 51, 52 respectively. Two stoves of a set of three are heated simultaneously and a proportion of the waste gases is returned for diluting the fuel gas supplied through pipe 41. When a stove has reached the proper temperature the gas and air are shut off and the stove purged of air by continuing the admission of flue gases from the pipe 49, the gases passing from the collecting flue 19 through a byepass pipe 57 and pipe 33 to the stack. The gas to be heated is then admitted through valve 56 from the cold gas main 55 and passed through ,the stove to a hot gas main and thence to the cracking system. When the temperature has dropped below the desired limit valve 56 is closed and flue gas again admitted to connection 51 and steam also admitted at 60, the chimney valve 21 being closed and the gases passing through the byepass 57 to the stack. The byepass 57 may communicate with a gas holder for storing the combustible gas displaced. When fuel of low calorific value is used in the burners 13 the amount of flue gas returned is reduced or the return for diluting purposes discontinued. Air supplied to the burners 13 is preheated in a recuperator 31; a valve 27 in the waste gas passage 25 determining the proportion of flue gas passed through the recuperator.

Abstract: 1474514 Television RCA CORPORATION 9 July 1975 [25 July 1974] 28881/75 Heading H4F Read-out of a charge-coupled image sensing array is effected with horizontal interlacing (and preferably also vertical interlacing) to improve the horizontal resolution and reduce MoirÚ pattern production. The known system comprises a photosensing array from which charge carriers accumulated therein as a result of exposure to a light or infra-red image are transferred into a temporary storage array and from these a line (row) at a time into an output register from which they are read a bit at a time. As shown in a two phase array, horizontal interlacing of a vertically interlaced pattern is achieved by dividing each channel (column of sensing and temporary storage elements) into two channels by locating between channel stops 30a and 30b a channel stop 31a and between channel stops 30b and 30c a channel stop 31b &c. These channel stops run down the entire length of the photo-sensing array and temporary storage array but the output register 14 is not modified thus there is only one register stage for each pair of channels. Thus during odd fields, Fig. 4a, the charge collected under the K electrodes in each column is shifted through the photosensing and temporary storage arrays and the charge present in two adjacent columns, such as Ja and Jb is combined into a single stage J of the output register. During even fields, Fig. 4b, the charge from adjacent channels such as J b  and (J+1) a  is combined into a single stage J. Horizontal interlacing with vertical interlacing is described for a three phase array with reference to Figs. 5a and 5b with Figs. 9 and 10 or Figs. 11 and 12 (not shown). Reference is made to various different interlaced patterns Fig. 13 (not shown) including four fold vertical interlacing.
