Title: An analogue-digital converter with automatic correction of its recoding factor
IPC: G01K1/02
Filed: 1968-06-21
Abstract: 1,222,142. Selective signalling. LICENTIA PATENT - VERWALTUNGS G.m.b.H. 21 June, 1968 [23 June, 1967; 8 Sept., 1967], No.29811/68. Heading G4H. In a circuit in which a voltage, for example from a temperature sensitive resistor RÁ Fig. 2, is digitized by amplifying 7 the voltage, converting 8 into a corresponding frequency, and counting 12 the cycles thereof for a known period, the counting period is determined by a " zero point " number 11 and "time " number 16, whereby the final count can be made to be zero for 0 degrees and 10,000 for 100 degrees, for example, and means 4, 5 are provided for periodically entering reference voltages corresponding to 0 degrees and to 100 degrees during periodic calibrating intervals whereby the stored numbers can be checked and corrected. In normal operation, initially the complements of the stored " zero point " and " time " numbers are transferred into zero point 10 and time 15 counters respectively. A gate 9 is then opened and cycles of the unknown frequency pass to the zero point counter 10. When this counter becomes full, cycles then pass to the main measuring counter 12, and this continues until the time counter 15 has become full of clock-pulses. During a calibrating period first the 100 degrees voltage is entered, and a cycle, as outlined above commences. If the stored numbers are correct then the main counter and the time counter should become full simultaneously. If one becomes full before the other, one of two gates 13, 14 is opened allowing low frequency clock pulses to increase or decrease the stored " time " number 16, until both have become full. The " time " number having been corrected, the 0 degree voltage is applied and the " zero point " number is corrected. To effect this, cycles of the corresponding frequency are counted in the zero point counter 10 for the entire period determined by the time counter 15, and the result is taken as the new zero point number.

Title: Process and machine for stripping or stemming tobacco
IPC: A24B5/06
Filed: 1930-10-07
Abstract: 364,185. Tobacco-stemming machines. HUYSTEE, A. M. J. VAN, 8c, Fagellaan, Heemstede, Holland. Oct. 7, 1930, No. 29970. [Class 130.] In a machine for stemming tobacco leaves, the leaves are suspended and moved so that the stripping members commence stripping at the top, then pass below the leaves and out of contact therewith and afterwards move upwards and finally inwards against the leaves near to their upper ends. As shown in Fig. 1, the leaves are clamped at their ends between intermittently moving co-operating belts 2, 4 so that they hang vertically downwards, and the belts pass between stripping elements 9, 10 arranged on opposite sides thereof. These elements remove the tobacco from the lower parts of the leaves which continue to move forward until encountered by a blast of air from a blower 21. The blast bends the leaves and compels them to enter co-operating intermittently moving belts 13, 14 adjacent which are stripping elements 17, 18 by which tobacco is removed from the remainder of the leaves. A conveyer belt (not shown) beneath the belts 2, 4, 13, 14 removes the stripped tobacco. Before stripping the tobacco a knife 23 severs the top ends of the leaves. The stripping elements are driven by cranks 35, 36, Fig. 3, actuated by an electric motor 39 and are mounted on beams 28, 29, fixed on rods 30, 31 resiliently mounted in frames 32, 33. Stops 48 on the rods 30, 31 contact with fixed members 49 during the rotation of the cranks thus causing the stripping elements to follow the contour indicated at 50, 56. In a modification, the second set of stripping elements is dispensed with, the top part of the leaves being severed by a knife after the lower part has been stripped. Stripping elements may be arranged on one side of the leaves only, the elements then entering holes in a wall on the other side of the leaves, and the conveyer belts may be replaced by pincers for conveying the leaves.

Abstract: 748,920. Pneumatic single-stroke apparatus. WILLIAMS, R. S. Sept. 30, 1954 [Nov. 4, 1953], No. 30422/53. Class 8(2). [Also in Group XXIX] A pneumatic power transmission apparatus comprises a main pneumatically operated piston 19 in cylinder 17, a secondary pneumatically operated piston 27 in cylinder 13, a supply pipe 32 for feeding air to effect the working stroke of the main piston 19 and a valve 36 in the pipe 32 which operates at a predetermined pressure to direct the air for effecting the working stroke of the piston 27 the effort of the piston 27 being transmitted to the main piston through the medium of hydraulic fluid. The piston 19 is formed with a bore 23 slidable on a boss 22 secured to a partition 11 and having a bore 26 in which the rod 28 of the piston 27 is slidable. In the outer end position of the piston 27 the bore 26 communicates through ports 30 with hydraulic fluid in the chamber formed between the outer casing 10 and the cylinder 17. Air initially acts on the piston 19 to push the rod 20 outwards until the pressure rises to open the valve 36 to supply air to the piston 27 which transmits power to the piston 19 through the hydraulic link. In a modification, Fig. 4, the cylinder 40 is surrounded by a member 48 of resilient material and filled with hydraulic fluid connected to the inner end of the cylinder 40 containing the piston 42. Air pressure is applied to the outside of the member 48 and the piston 42 is thereby moved through the hydraulic link until the hydraulic and air pressure are balanced whereon a valve 58 is opened to actuate the piston 46 which as above described acts through the hydraulic link on the piston 42.

Title: Copper chloride sweetening of catalytic naphtha
IPC: C10G27/08
Filed: 1957-10-01
Abstract: <PICT:0871512/III/1> Sour catalytically cracked naphthas are sweetened by dispersing therein a granular composition, consisting of cupric chloride, a carrier and 3 to 7% wt. of water, in the presence of sufficient free oxygen to react with substantially all the mercaptans in the naphtha, for sufficient time to render the naphtha doctor sweet and separating the sweet naphtha from the composition. The treated naphtha may contain a minor proportion of thermally cracked and/or virgin naphtha and may have been subjected to a preliminary treatment, e.g. with dilute aqueous caustic soda to remove H2S or by the solutizer process to reduce the mercaptan or sulphur content.  Any caustic soda left in the feed interferes with the sweetening process and may be removed by passing the feed through rock salt, steel wool, gravel, sand or any other coalescing medium. Sour naphtha from line 12 passes through salt filter 13, heat exchanger 16 where it is heated to 27 DEG C., and line 17 to mixer 18, where it is thoroughly intermingled with oxygen (3 to 9 S.C.F. O2/lb. mercaptan sulphur or the equivalent of air) introduced into line 17 from line 22.  The naphtha is then pumped by pump 36 through line 37, line 42 or eductor 38 and line 39 to reactor 41.  Some of the sour naphtha from line 17 is diverted via line 24 to slurry tank 26, where it is mixed with a composition consisting of 8 parts by weight of finely divided Attapulgus clay (particle size <0.177 mm.) and 1 part CuCl2 and 5% of water (by weight of the total).  This slurry is pumped via pump 31 and line 32 into line 37.  Dense slurry which settles in reactor 41 is recirculated at a rate of 10 to 30% vol. (based on the naphtha) via line 47, eductor 38 and line 37. Spent treating composition may be discharged through line 49. Sweetened naphtha is removed from reactor 41 through lines 51 and 52, washed with water from line 54 in mixer 56 and transferred via line 57, settler 58 and lines 61 and 63 to cooler 64.  The water wash may be by-passed by line 62.  The cooled naphtha passes through line 66, salt filter 67 and line 69 to mixer 73, where it is mixed with a metal deactivator such as N, N1-disalicylidine-1,2-diamino-propane from line 72 and removed to storage via line 74.  The efficiency of the process is contrasted with that of conventional processes wherein the CuCl2 composition contained 10 to 16% wt. of water.

Title: Manufacture of cricket or hockey balls
IPC: B29D99/00
Filed: 1948-11-26
Abstract: A method of manufacturing a core for a cricket or hockey ball comprises preparing a homogeneous rubber mix containing vulcanizing agents and fillers and a chemical substance such as ammonium carbonate or sodium bicarbonate which, under heat, is readily decomposable and gas-evolving, moulding the mix in a fluid-tight mould completely filled and closed and subjecting the closed mould to the heat and pressure necessary for vulcanization of the mix so as to produce a core which, to the naked eye, is free from porosity and from gaseous cells and inclusions.  The vulcanized core is then coated with a rubber solvent and has moulded thereon a cover of guttapercha and leather shreds. Alternatively the core mix is moulded, coated with solvent and covered and the complete ball vulcanized together.  Before vulcanizing, the core may have guttapercha chips impressed therein, which, on vulcanizing, produce a film of guttapercha on the core to promote bonding of the core and cover.  Suitable mixes and vulcanizing data are described in the Specification. Specifications 221,708, [Class 132 (ii)], 453,185 and 638,913 are referred to.  Reference has been directed by the Comptroller to Specification 638,913.
