Title: Decimal accumulator and/or self-decoding digital display unit
Inventor: CLEMENT CARL LOVELACE
IPC: G09G3/04
Filed: 1962-08-14
Abstract: 1,001,423. Digital display unit/selective signalling/counting apparatus. KAUKE & CO. Inc. Aug. 14, 1962, No. 31127/62. Headings G4D, G4H and G5C A display unit 10 comprises a shutter plate 13 having a plurality of transparent regions 14, through which portions of a master plate 15 are visible, and means for relatively shifting the plate through discrete positions, so that different indicating regions of the master plate become visible (Fig. 2). As shown, a coil 19 actuates an armature 21, on which is mounted a pawl 23 which moves a ratchet wheel 25 by one tooth for every electrical pulse passing through the coil. The wheel 25 rotates a shaft 32 carrying a spiral cam 28, which moves the master plate 15 through the discrete positions every half turn, causing the digits 0 . . . 9 to be seen through plate 13, as a series of vertically spaced horizontal lines (Figs. 1, 5, not shown). Shaft 32 carries an indexing wheel 26 and a drum 33. The drum carries a series of paths 34<SP>1</SP> . . . 43<SP>1</SP> of conductive and non-conductive sections engaging wiper arms 34 . . . 43. The unit may be " zeroed " by applying a potential to a terminal 51 causing current to flow via the conductive sections of paths 351, 34<SP>1</SP>, arm 34, contacts 45, 46 (Figs. 7, 8) to energize the coil 19. Contacts 45, 46 separate every time the wheel 26 moves, and the coil operates until the non- conductive portion of path 35<SP>1</SP> engages the wiper 35 and breaks the circuit, when the zero numeral registers. The unit may be used as a decimal counter, each pulse applied to an input terminal 50 actuating coil 19 to display successive numerals. An extra wiper arm, engaging an extra path on drum 33 whose conductive surface connects the arm with continuous conductive path 34<SP>1</SP> only when the zero numeral is registered, may serve to apply the incoming pulse to a further unit, the two units together thus counting up to number 99. In an alternative means of operation, terminal 50 is not used but a binary number input, received by wipers, 36-43, is translated into a decimal number displayed by plates 13, 15. Arms 40 ... 43 receive inputs representing successive digits of a binary number, e.g. 0110#6, and arms 36 . . . 39 receive inputs representing the complement of the number, e.g. 1001#6. Thus when the input representing numeral 6 is received, e.g. from a computer, arms 36, 39, 41, 42 are energized, representing digit 1, and arms 37, 38, 40, 43 are not energized, representing digit 0. The drum is then rotated, by virtue of coil 19 being energized through the conducting paths on drum 33, until all energized arms are contacting non- conducting portions of their respective paths, which, as Fig. 7 shows, corresponds to position 6 of the drum and to display of numeral 6 by the plates.

Title: Expansible volume analyzer sample cell for colorimetric analyzer
IPC: G01N21/05
Filed: 1959-09-14
Abstract: 884,863. Spectrometric cells. S.L.F. ENGINEERING CO. Sept. 14, 1959 [Sept. 15, 1958], No. 31226/59. Class 97(1). A sample cell for colorimetric analysis has a completely enclosed fluid chamber of expansible volume, formed by a cylindrical bore in cell body with a bottom closure and a flexible diaphragm as the top closure, and fluid inlet and outlet means. As shown in Figs. 2 and 4, the cell body 50 has windows 60 for the diametric passage of the light beam through the cylindrical cavity 52 which is provided with an inspection window 56 and at whose upper end is fitted a rubber diaphragm 66 for depression by a compressed-air-driven piston 74 which when seated on the bevelled portion 72 defines a predetermined cavity volume. Excess fluid is expelled by the piston pressure through an outlet bore or bores (shown dotted) at the top of the cell and an outlet port 110 controlled by valve 118. The inlet port 108 controlled by valve 116, communicates with a bore or bores (shown dotted) entering the bottom of the cell cavity tangentially to cause swirling of the incoming fluid. The valves are contained in a valve block 100 fixed by any desired means, and with a rubber gasket 102 interposed, to the cell body. Fixed to this block 100, with the interposition of diaphragm 124 is a further block 126 containing slidable pistons 132, 134 in cavities aligned with the valves. A cap 138 fixed to block 126 has an air inlet nozzle 146 so that air under pressure from a pneumatic control mechanism entering a recess in the cap 138 distends the rubber diaphragm 135 to exert closing pressure on the valves via the pistons 132, 134. Reagents can be added to the cell via the injection nozzle 148, the additional volume being provided by distension of the diaphragm 66 against the unrestrained piston 74. A freelyrotatable plastic covered magnet 80 at the bottom of the cell cavity is caused to rotate, thereby providing stirring action, by means of a motor-driven rotating magnet 82 mounted below it. Specification 31225/59 is referred to.

Title: Improvements in multiple spindle lathes or like machines
IPC: B23B9/02
Filed: 1945-11-20
Abstract: 613,434. Lathes. CONE AUTOMATIC MACHINE CO., Inc. Nov. 20, 1945, No. 31252. Convention date, Nov. 20, 1944. [Class 83 (iii)] A multiple spindle lathe or like machine comprises a number of work spindles for bar stock, means for producing tooling operations on such stock, and stops for selectively preventing certain tooling operations on stock held by predetermined spindles to cause production of a number of differently-machined articles from a number of bars. A pair of tool slides 3, Fig. 1, is provided at the front of the machine operated from a vertical sleeve 13 and shaft 15 which are rotated from an overhead cam drum and links 10, 11 in accordance with usual "cone " multiple spindle turret lathe practice. A resilient connection is, however, provided between the vertical members and the tool slides in the form of a link 16, Fig. 4, a rod 17, and a spring 19 compressed between a collar 21 on the rod, and the tool slide 18. The spring is sufficiently strong to resist any compression during a normal cutting stroke, but when a deeply projecting stop member 30 on a bracket 22 carried by the tool-slide strikes an abutment 31, preventing normal feed of the tool, the spring gives. A series of adjustable stops 30, 30a, one for each spindle of the turret, is carried by the bracket 22 provided on each tool-slide ; in the example shown, similar tool-slides are carried at the back of the machine opposite the front tool slides. The two abutments 31 for the front tool-slides are carried on a vertically slidable strip 32 moving in guideways 33, Fig. 4, secured to the machine frame and moved down into line consecutively with fresh stop members 30 by a linkage 40, 41, 42 under control of stop members 43 spaced equally around the turret. Where a cutting- off tool is required to operate only on workpieces in alternate spindles a stop arrangement, as shown in Fig. 5, is used where stops 30 extend sufficiently to prevent contact of the tool and work on alternate spindles coming adjacent the tool-slide. A work cycle is also described employing alternately large and small chucks in the turret to accommodate work which is first turned down and then reversed. Specification 456,284 is referred to.

Title: Improvements in surface coverings
IPC: D06N5/00
Filed: 1948-12-03
Abstract: 652,848. Coated fabrics. BRUCE, D. Dec. 3, 1948, No. 31326. [Class 140] A covering comprising a strain-resistant base sheet composed of a unitary felt or the like of which the layer adjacent to one surface is impregnated with a binder that affords relatively high internal strength, and the layer remote from that surface is treated so as to have internal strength which is less than that of the first layer but greater than that of the untreated sheet. The felt may be impregnated on one side with bituminous material, e.g. molten asphalt, so that it strikes through about two-thirds of the thickness of the felt. A solvent for the bitumen, such as petroleum spirit, shale spirit, shale naphtha, pool rubber solvent, benzene, xylene, coal tar naphtha, carbon tetrachloride, or methylene dichloride, is then applied, as by a roller wetted by the solvent, to the unimpregnated side of the sheet, and the sheet passed through a hot chamber to evaporate the solvent which dissolves some of the bitumen and on drying deposits it on the previously uncoated fibres.
Patent GB-485372-A (GB)
Title: Improvements in the treatment of artificial yarns, fabrics, films and the like
IPC: D06M15/39
Filed: 1936-11-16
Abstract: Yarns, fabrics, films and the like of organic derivatives of cellulose are rendered creaseresisting by causing the material to absorb from a non-aqueous solution in a liquid having a swelling action on the material, synthetic resin components or an intermediate condensation product of such components, and forming a water-insoluble resin on the material.  The material is preferably dried at room temperature after impregnation and before heating to condense the resin, the impregnation and drying may be repeated several times.  Impregnation is preferably effected under acid conditions.  All reagents used are free from water, and the material to be treated is preferably subjected to a preliminary treatment to remove water, e.g. an extraction with anhydrous alcohol, or by heating.  Formation of a resin film on the material is prevented by subjecting to mechanical treatment as described in Specification 485,199 or by scouring with a mildly alkaline solution.  In an example, urea and formaldehyde dissolved in methanol are pre-condensed in the presence of caustic potash, acetic anhydride added and the solution allowed to stand; the solution is acidified with conc. sulphuric acid and a cellulose acetate fabric immersed therein, air-dried and heated to 180-200 DEG  C. for about 5 mins. Instead of methanol there may be employed ethyl acetate, methyl formate or methyl acetate; liquids such as ethyl acetate which are solvents should be be diluted with non-aqueous diluents, e.g. ether or benzene.  Instead of urea there may be used thiourea, dicyandiamide, biuret, guanidine, phenols, aromatic aromatic amines, e.g. aniline, and sulphonamides, e.g. p-toluene sulphonamide. Materials so treated also have an increased affinity for acid dyestuffs, retain mechanical effects such as crimping in yarns or embossing, and have an increased resistance to water.  Local effects may be produced by effecting the polymerization or condensation locally. According to the first Provisional Specification other suitable resins are the polybasic acid polyhydric alcohol type. Polyvinyl and poly-acrylic compounds may also be used.  It is stated that instead of resins, substances such as ester resins, rubber, guttapercha and balata may be employed.  Other suitable swelling agents are acetone, diacetone alcohol, dioxane and ethyl acetate.

Title: A transducer for converting liquid pressure oscillations into mechanical oscillations
Inventor: FOSTER KEITH
IPC: B06B1/18
Filed: 1968-07-02
Abstract: 1,253,538. Liquid actuated rock drill. A. F. HYDRAULICS Ltd. 17 June, 1969 [2 July, 1968], No. 31606/68. Heading B4C. [Also in Division F1] In a transducer for reciprocating a rock drill bit 19, Fig. 1, wherein a piston 11 is oscillated in a cylinder 12 by pressure pulsations applied to at least one of the chambers 13, 14 on opposite sides 21, 22 of the piston, excessive movement of the piston to one side thereof e.g. to the right displaces an axially movable valve 27, Fig. 3, whereby pressure fluid within a storage container 28 is passed to cylinder chamber 14 thereby returning the piston to its central position; the container 28 being maintained at a pressure greater than the algebraic mean pressure in chamber 13 by means of a flow regulator valve 26. As shown both chambers 13, 14 are subjected to pressure pulses of opposite phase and the piston 11 comprises large and small area lands 21, 22. A shoulder 39 on land 21 abuts a flange 37 of valve 27 and serves to displace the valve against a spring 39a until a valve land 32 becomes unseated from the fixed valve body 30 resulting in oil container 28 being connected through a port 35 to chamber 14. On further movement of the valve 27 a second land 36 becomes unseated from the valve body 30 and chambers 13, 14 become directly connected and piston reciprocation ceases. Pist on lands 21, 22 are formed on a sleeve 16 slidable on an inner rod like piston member 17 carrying a heavy mass 18 at one end and having at its other end a counterbore engaged by a relatively slidable plunger 60, Fig. 5, rigid with the outer end of sleeve 16 and forming an act filled dash pot device 54. The mass 18 slides within a sleeve 45 spaced radially inwardly of the end of cylinder 12 to provide an oil-filled space 46 provided with a damping valve whereby should the piston move excessively to the right e.g. due to the tool 18 breaking through soft material, the sleeve 45 yields to the mass 18. The outer end of piston sleeve 16 is supported by a bearing 80 which may be of the resilient type. In a modification the piston 11, Fig. 8, is in one tubular piece and is slidably connected at one end 98 by a tubular spigot 96 held on a spherical seat 100 of the cylinder end by a split clamp ring 102. Oil leakage is passed through a return line 104 and the piston interior is vented to atmosphere through a filter 108.

Abstract: 881,077. Knitted fabrics. REYMES-COLE, B. T. R. Jan. 17, 1958 [Oct. 17, 1956], No. 31615/56. Class 74 (2). Groups of not more than twenty-four part courses, formed by reciprocatory knitting, are inserted at any or all of regions such as 11-15, 19, 20, 23 and 25 of a circularly knitted stocking providing narrow coursewise strips without substantially altering the shape, to give additional fullness to the fabric when stretched, or for ornamental and/or marking purposes: particularly for this last purpose, the insertions may be formed from a separate yarn which may be coloured with a fugitive dye. Eyelets 20 or 26 may be formed at the ends of the insertions. The eyelets 20 may converge downwardly towards the back line to simulate fashioning marks. The part courses may be knitted on spaced groups of needles within the section of the needle circle used for the reciprocatory knitting and separated by a shorter group of inactive needles, so that there are formed, in coursewise correspondence, two spaced insertions and therefore two sets of eyelets 20. The eyelets 26 may be large enough to receive the buttons of suspender clasps. The eyelets may be accentuated by reduction in length of part courses intervening between the end ones in an insertion. The yarn in any or all insertions may be one possessing stretch properties, e.g. bulked nylon yarn; or it may be of cotton. Thermoplastic yarn may be incorporated in the region of the heel and toe or over the whole of the blank, which is shaped by boarding after closure of the toe. Specifications 756,841, 756,861, 832,518 and 880,516 are referred to.
