Title: Improvements in or relating to grabs
IPC: B66C3/08
Filed: 1926-02-02
Abstract: 266,521. Sedgwick, H. F. F. Feb. 2, 1926. Grab-buckets.-Relates to single chain grabs discharged in mid-air bv co-operation of a latch-hook C with a suspended ring c<1>, and of the type in which the grab-head d and the lower bridge e are connected by toggle links i, i<1>. The toggles pass beyond their dead-centre when the buckets are open, Fig. 2, so that the device is self-locking and the open grab may be supported free of the ring c<1> by the bight of the hoisting rope or chain passing round pulleys in the bridge, as shown in Fig. 3. The pivot pins k, k<1> of the toggle links pass through slots l, l<1> in the grab head and bridge. The pivot pin k<1> is secured to the pulley block g which is pivoted at g<1> in the bridge, the pin k<1> moving in the slot l<1> as the block turns about g<1>. The latch hook c is pivoted directly on the upper toggle link i at c<2> and tends to fall outwards but is held in position to engage the ring c<1> by the cranked end i<3> of the lower toggle link when the buckets are closed, as shown in Fig. 1. When the grab is lowered from the position shown in Fig. 1, the hook c engages the ring c<1> and the buckets open, as the hoisting rope is payed out, the toggle levers opening to the position shown in Fig. 2. On lifting the grab the latch c falls outwards, or is thrown outwards by a projecting part (not shown) on the body of the ring c<1>, and the grab may be lowered with the buckets open. When the bridge e rests upon the ground, the block g moves downwards on its pivot g in the bridge, bringing the pin k<1> to the bottom of the slot l<1> in the bridge. The arm i<3> of the toggle lever i<1> is supported by a stop m on the bridge so that the movement of the pin k<1> in the slot l<1> brings the toggle levers over their dead centre and the buckets may be closed by hauling in the hoisting rope. The toggle-links may be at one or both sides of the bridge.
Patent GB-630900-A (GB)
Title: Improvements relating to processes for the production of edible syrups
IPC: C13K1/08
Filed: 1947-01-31
Abstract: In a process for preparing an edible syrup from a residual syrup of the sugar industry, in which the syrup after being diluted if necessary, is inverted, decolourised and again concentrated if necessary, the syrup is heated prior to the decolourisation with an alkali metal phosphate after which the precipitate formed is separated and the syrup is decolourised by treatment with an artificial resin.  The inversion may be effected after the treatment with the alkali metal phosphate and the artificial resin.  A small proportion of lime, e.g., 50-200 mg. CaO/litre is added if the syrup contains a small quantity of Ca compounds.  The amount of alkali metal phosphate used varies between 0.5 and 5 per cent. on the dry material of the syrup. Beet sugar syrup is best treated in alkaline medium and if it becomes too alkaline owing to the added phosphate no precipitate or only an insufficiently large precipitate will be formed.  In such case acid such as citric, tartaric, sulphuric or phosphoric is added to prevent the pH rising which preferably should not exceed 8.5.  Cane sugar syrup is best treated in an acid medium and the amount of alkali metal phosphate used is 3-4 per cent.  A di- or mono-alkali metal phosphate is preferably employed to avoid too great an increase in pH.  Acid may be added if necessary so that the syrup has a pH 6-7.

Filed: 1958-01-31
Abstract: <PICT:0848125/III/1> In an automatic titration apparatus, the liquid to be tested is fed into a vessel 1 from which a standard volume is discharged at intervals through a siphon 2 to a collecting vessel 4. The discharge creates a vacuum which draws into the tube 3 a standard amount of titrating liquid from a Marriotte vessel 13 through a siphon 22.  The collected liquid is then led into a dosimeter tank 27, and any change of colour estimated by photometer cell or by change in an electrical resistance.  The test liquid is continuously fed into the vessel 1 from an overflow tank 5 through a restricted opening 8, whereby the amount of liquid entering vessel 1 during emptying may be disregarded.  The restriction 8 is adjusted to a steady flow less than the discharge rate from the vessel 1.  A number of Marriotte vessels may be employed each containing a different titrating solution, and discharge a standard volume thereof through individual siphons either simultaneously into the collecting vessel, or in cascade into a series of collecting vessels.  In a modification, the collecting and dosimeter tanks are closed at the top and provided internally with a siphon tube.  The dosimeter tank is preferably the same volume as the amount of titrating liquid.

Title: Improvements in or relating to apparatus for severing glass tubing
Inventor: ASHER PHILIP
IPC: C03B33/085
Filed: 1957-02-01
Abstract: 826,270. Cutting glass tubing. GENERAL ELECTRIC CO. Ltd. Jan. 31, 1958 [Feb. 1, 1957], No. 3605/57. Addition to 808,284. Class 56. The apparatus of the parent Specification is provided with an electronic timing circuit for controlling its operation. The circuit includes microswitches M1, M2; relays RL1 ... 6, and delay circuits Dl... 4 which include coldcathode gas-filled valves with a control electrode between cathode and anode. The microswitches are operated by a cam 36 on the reciprocating carriage 9 ; one circuit controlled thereby is that including the means 18 for actuating one or other of the gripping means 16 or 17 to cause engagement thereof with the upper or lower lap of the driving chain 12 to determine the direction of travel of the carriage. On the carriage is mounted the bearing 20 in which the ring burner 8 is rotatably oscillated by the piston-and-cylinder 21 ... 23, the burner during the forward movement of the carriage preheating the annular zone of the tubing at which severance is to take place (the tubing fed by the feeder 3 being carried forward by the carriage during its forward movement). Severance of the tubing at the annulus thus pre-heated is effected by the passage of current therearound from electrodes 25 carried by the burners. Immediately after severance of the tubing a driven roller 41 is moved down to engage the severed length which is supported by other rollers 40. The function of delay circuit D1 is, after sufficient delay to enable burner 8 to preheat the zone, to energise RL1 and close R1.1 to allow current to pass through (normally closed) R2.1 thereby closing 31 to energise the primary 29 of transformer 28 to apply an A.C. of about 15KV to the electrodes 25. Delay circuit D2 at a predetermined instant energises R2 to open R2.1 and so cut off the current to the electrodes ; R2.2 also opens to cut off the current to 18 and so to release the upper grippers 16 from the chain and connect the lower grippers 17 thereto to start the carriage on the reverse journey. The delay circuit D3 effects the downward movement of the roller 41 to remove the severed length, or it could operate to lower the roller before severance actually occurs. The effect of the fourth delay circuit D4 is, at the appropriate time, to deenergise all the relays to leave all the controls in the condition for restarting when cam 36 contacts M2 at the end of the backward movement of the carriage.

Abstract: Carbocyanine dyestuffs, which are photographic sensitizers, are obtained by condensing one molecule of ethyl o-formate with two molecules of a 1-methyl-a - or b -naphthothiazolinium quaternary salt or two molecules of the corresponding oxygen, selenium or telurium analogue.  In examples: (1) 1-methyl-a -naphthothiazolethyl-p-toluene-sulphonate, or a halogen derivative thereof, formed by heating the thiazol with ethyl-p-toluenesulphonate, is condensed with ethyl-o-formate in the presence of pyridine, and the dyestuff, 2 : 21-diethyl-5 : 6 : 51 : 61-dibenzothiocarbocyaninebromide precipitated with aqueous ammonium bromide; (2) 1-methyl-a -naphthothiazol is converted into a quaternary salt with allyl iodide and is condensed with ethyl-o-formate by refluxing in pyridine solution.  The dyestuff 2 : 21 - diallyl - 5 : 6 : 51 : 61 - dibenzothiocarbocyanineiodide precipitates on cooling. Instead of forming the quaternary salt with ethyl-p-toluenesulphonate, methyl or propyl-toluene sulphonate may be used or a halide or sulphate.  Unsymmetrical cyanines may be obtained by using mixtures of quaternary salts of a - and b -naphthothiazoles for the condensation with ethyl-o-formate.
