Patent GB-134762-A (GB)
IPC: B23D3/04
Abstract: 134,762. Murray, W. April 23, 1919. Shaping curved surfaces.-In a machine for shaping propeller blades, the tool is moved across the blade from side to side by an oscillating arm along which it is fed automatically. Wheels 21, 22 rotating in opposite directions are loosely mounted on a shaft 19 having a double clutch 24 feathered, and a pinion 37 secured, thereon. This pinion engages a segment 36 secured to the shaft 35, which carries adjustable cams 39, 40 adapted to actuate the clutch 24 through a rod 33<a> and lever 32 to give an oscillating motion to the shafts 19, 35. The shaft 35 carries a stroke-indicator 90 and an arm 38 on which a saddle 43 carrying the tool 41 can slide radially. This movement is effected by a screw 45, ratchet 46, wedge 50, and stationary cam 53. When operating on the back of a blade, the tool is also fed forward as it approaches the edge of the blade in both directions, and this is effected by a semicircular track 82 which can be adjusted about its lowest point 83 by slotted brackets 86. The end of a spring- pressed bar 80 engages this track and is connected to a lever 78 engaging the tool-holder 42. When the track 82 is vertical, this feed does not take place, and the holder 42 may be locked by bolts 88. The propeller is adjustably carried by bracklets 3, 9 of a rotatable table 13, the blade 1 being supported also by set-screws 5. As the tool is fed towards the boss of the propeller this is given a gradually increasing rotary movement, to correspond to the twist of the blade, by a link 65 connecting nuts 66, 58, Fig. 2, on screws 69, 57 carried by the bed and the table 13 respectively. These screws are rotated by ratchet gear 70, 59, linkwork 72, 75 and 60, 61, and cams 63, 76 carried by the shaft 35. The screws 45, 57, 69 may also be adjusted by hand and the table 13 may be adjusted as a whole by cross-slides 14, 15. The pitch of any part of the blade may be tested by a sliding scale attached to the tool-holder and brought into contact with the work at two points whose angular distance apart is indicated by the disk 90, the table 13 being in its zero position as indicated by graduations thereon.

Title: Voltage-controlled adjustable counter
IPC: H03K25/00
Filed: 1965-03-30
Abstract: 1,094,403. Circuits employing magnetic storage elements. GENERAL TIME CORPORATION. March 30, 1965 [April 29, 1964], No. 13529/65. Heading H3B. [Also in Division G4] In an electronic counter 20, which provides a single output for a predetermined number of pulses " n " received from a pulse former 10, each pulse enables a transistor Q103 to draw current pulses through a coil CN1, CN2, CN3 from a fixed voltage supply E and a variable supply Ea, each current pulse gradually saturating a core 22 in a direction opposite to its initial state, and the nth pulse over-saturating the core in this direction. The saturation of the core then falls to its residual level and the resulting change in flux in the coil CN2 produces a trigger signal to render a second transistor Q104 conductive, which thus allows current to be drawn through the coil CN3 to reset the core 22 to its initial saturation state. This reset operation produces a single output pulse in coil CN5. The number of pulses " n " required to over saturate the core 22 and thus produce an output pulse, is determined by the voltsecond content of each pulse and this may be varied by adjusting the voltage supply Ea. A number of such counters may be incorporated in a counting system (Fig. 3, not shown) in which the units, tens and hundreds values are preset on variable 1 to 9 counters (U20, A20T and A20H). When the units value has been counted a signal shuts off this counter and activates a decade counter (AF20T) whose output pulses, corresponding to 10 input pulses, are applied to (1 to 9) counter (A20T) which has been set to a value corresponding to the number of " tens " to be counted. Upon completion of the tens count a signal diverts the output of the decade counter (AF20T) to a further decade counter (AF20H) and variable (1 to 9) counter A20H), each output of the latter corresponding therefore to the number of " hundreds " counted together with the tens and units count already recorded by the other sections (U20) and (A20T). Each such onput is applied to a terminating module which transmits the working output pulses to a relay and which also resets the flip-flops that control activation of the various counter stages. If a predetermined count number contains zeroes and if a zero is a higher order zero the corresponding section is by-passed, the output of the previous counter-stage being applied to the next higher order stage or to the terminating module, as appropriate. If a zero is a lower order zero the next higher order section is activated simultaneously with the zero stage, the latter being thus effectively ignored.

Patent GB-439802-A (GB)
Title: Improvements in the process of bleaching textile materials
IPC: D06L4/15
Filed: 1934-05-07
Abstract: Textile materials are bleached by a non-alkaline liquor containing hydrogen peroxide or a compound, such as a percarbonate or perphosphate, yielding hydrogen peroxide in aqueous solution, the liquor being fully inactivated by the addition of an inactivator other than sulphuric, nitric or hydrochloric acid, with application to the materials, before their introduction into the liquor of an activator which is retained by the goods without substantial diffusion into the liquor.  the inactivator and the activator are both free from metal of atomic weight above 45.  The textiles may be of animal fibres such as hair or wool or of vegetable fibres such as jute.  Specified inactivators are phosphates, borates, oxalates, lactates, isobutylnaphthalenesulphonic acid and oleylmethylaminoethanesulphonic acid and glue is specified as an auxiliary inactivator.  Specified activators are enzymes, ferments and soap.  The goods containing the activator may be subjected to a short wetting with the bleaching liquor, e.g. by immersion, sprinkling or brushing, and the bleaching completed by storing in a moist state or by applying heat.  Bleaching may be effected first by a weak and later by one or more stronger solutions and the textile material and the bleaching liquor are preferably moved in opposite directions during the treatment.  The following examples are specified: (1) Animal hair, e.g. Angora goats' hair or sheep's wool is washed with soap and water, rinsed so that it retains about 1 per cent of soap, worked into tops which are placed for 2 minutes in an aqueous bath at 40 DEG  C. containing hydrogen peroxide and oxalic acid with or without an oxalate, hydroextracted or squeezed and dried.  (2) Wool in the form of tops is placed for 30 minutes at room temperature in a solution of potassium permanganate slightly acidified by sulphuric acid or with an addition of magnesium sulphate; the wool, thus stained brown and made slightly alkaline, is rinsed while retaining alkalinity and placed for 2 minutes in a bath at 30--40 DEG  C. containing hydrogen peroxide, sulphuric acid and sodium oxalate and, still retaining alkalinity, is placed for 10--30 minutes in a similar bath containing hydrogen peroxide and oxalic acid; it is then rinsed, cleared in a solution containing sodium bisulphite and sulphuric acid, and, if bleaching to a pure white is desired, is further treated for 3--6 hours in a solution of sodium hydrosulphite at 35--45 DEG  C. and finally rinsed and acidified; softness in the bleached material may be attained by adding a protective colloid, e.g. glue or tanning matter, to the bleach liquor and its feel may be improved by a preliminary treatment with an aldehyde, e.g. formaldehyde or acetaldehyde or by adding such to the bleach liquor.  Specification 404,019 is referred to.

Title: Process for heating coke oven batteries with hydrocarbons particularly petrol
IPC: C10B21/00
Filed: 1958-05-05
Abstract: 879,117. Combustible gas; recirculating combustion products. DIDIER-WERKE A.G. May 5, 1958 [Aug. 19, 1957], No. 14217/58. Classes 51 (1) and 55 (2). In a process for heating a coke-oven by the use of carburetted gas, particularly an oven operating on the regenerative principle and wherein the direction of flow of the heating gases is periodically reversed, part of the flue gases produced in the heating of the coke-oven is recycled, carburetted by the injection into it of petrol or other volatile hydrocarbon and the mixture of flue gas and vaporized hydrocarbon is burned in the flues of the coke-oven. The recycled flue gas may be washed to remove sulphur dioxide until such a time as the flue gas being recycled contains no sulphur di-oxide and the carburetted gas may have a calorific value of 4000 KCal/Nm <SP>3</SP>. The luminosity of the combustion of the carburetted gas in the flues of the coke-oven may be reduced by adding air to the carburetted gas before it is fed to the heating flues to give the gas an oxygen content of about 8%. During the reversal of the direction of flow of the heating gases the pump injecting the hydrocarbon into the flue gas may be automatically stopped by the mechanism controlling the valve changes for the reversal of flow.
