Patent GB-380062-A (GB)
Title: Process for the manufacture of anthraquinone derivatives containing nitrogen
Filed: 1931-06-06
Abstract: Quinones of the anthracene series are obtained by causing a hydro compound of a hydroxy-anthraquinone containing at least 2 hydroxyl groups in the 1 : 4-position to react in acid solution or suspension with an oxidizing agent, such as manganese dioxide, lead peroxide, red lead and lead tetracetate, the acidity of the medium being adjusted so that intramolecular rearrangement of the resulting quinone cannot occur.  Organic acids, such as acetic, may be employed in any concentration, and the acidity of inorganic acids used should not in general exceed that of 25 per cent sulphuric acid.  Mixtures of acids, e.g. of glacial acetic acid and dilute sulphuric acid, may be used.  The products, which are hydro-quinizarin-1 : 4-quinones, are reconverted by sulphurous acid into the hydro-hydroxyanthraquinones, or by strong acids to the hydroxyanthraquinones.  The hydroquinizarin quinones obtained according to the first part of the invention, on treatment with primary aromatic amines, give arylamino derivatives of hydroxyanthraquinones, with the probable intermediate formation of imino-quinones.  According to examples, hydroquinizarin and hydropurpurin are oxidized to the corresponding quinone with manganese dioxide in dilute sulphuric acid; hydro - 1 : 4 : 5 - trihydroxyanthraquinone (obtainable from the 1 : 4 : 5-trihydroxy compound by a process similar to that used for hydroquinizarine) and hydro-1 : 4 : 5 : 8-tetrahydroxyanthraquinone (obtainable by reducing the tetrahydroxy compound with hydrosulphite in aqueous-pyridine solution) are oxidized in glacial acetic acid with lead tetracetate, giving in the latter case a diquinone corresponding to the 1 : 4 : 5 : 8-tetrahydroxy compound on treatment with twice the quantity of lead tetracetate; on treatment with p-toluidine, p - aminoacetanilide, anthranilic acid, sulphanilic acid, and anthrone of b  - aminoanthraquinone, hydroquinizarin quinone gives the corresponding 1-arylamino-4-hydroxy compounds, and hydropurpurin quinone also reacts with p-toluidine in a similar manner.

Title: Dispenser for unbottled beverages
IPC: G07F13/10
Filed: 1972-04-11
Abstract: 1332618 Coin-freed beverage vending machine BRAS SpA 11 April 1972 [13 April 1971] 16619/72 Heading G4V In a coin-freed beverage vending machine that includes a cup dispenser 3, a beverage dispenser 4, and a cup sensor 5 located at the beverage dispensing location for controlling the timed operation of the beverage dispenser, a latching device 2 for blocking the acceptance of coins is actuated on the insertion of a first coin but is deactuated before the termination of the beverage dispensing cycle, thus allowing another cup to be dispensed in readiness for the next cycle. In the embodiment shown an inserted coin closes switch 1 which sets a bi-stable circuit 8 that controls latching device 2 and cup dispenser 3 via switching circuits 9, 11 and timer 10, and sets a circuit 13 in its "consent" condition. When a cup is properly positioned to receive the beverage, switch 5 is closed which is effective through circuits 13, 87 and 15 to initiate the dispensation of the beverage for a time as determined by timer 14. On actuation of the beverage dispenser 4 a circuit 16 is set to reset the bi-stable circuit 8 and hence deactuate the latching device 2. The circuit 13 is held in its "consent" condition until dispensation of the beverage is completed. A detailed circuit is shown in Fig. 2 (not reproduced).

Abstract: 399,278. Starting prime movers. BOHLI, J., 304, Obach, Solothurn, Switzerland. June 14, 1932, No. 16737. [Class 38 (iv).] In an electric starter in which the shaft of the starter pinion 5 is coupled to the armature shaft 17 by a free-wheel clutch and a multiple - disc friction clutch 8, and the main switch of the motor is closed after the pinion 5 is fully in mesh with teeth 6 on the engine flywheel, the armature 1 is first caused to rotate in the reverse direction, so that the pinion is rotated slowly by the friction in the freewheel clutch and no damage is caused if the pinion clashes with the teeth 6. On moving the pinion shaft axially by means of a lever 9, an additional field coil 3 is switched in by a contact 10 and the armature 1 is rotated in the reverse direction. When the pinion 5 is fully in mesh with the teeth 6, the main field coil 2 is switched in by contacts 11 and the current in the coil 3 is reversed by means of contacts 12, so that the field created by the coil 3 reinforces that of the main coil 2. Specification 398,623, [Group XXIV], is referred to.

The table is guided by sliding jaws 11 on the bracket 14 and has a spring-pressed clamp 3 for engaging the back edge of the saw, such as a band saw, the saw being resiliently held on the table by a spring-pressed lever 10. A bearing on the lower face of the table is engaged by the eccentric 5 which is adjustably carried by a disc 12 on a drive shaft 6. Rotation of the shaft causes the table to move in a circular motion. During the first quarter of the table movement, the saw is retracted from the grinding wheel, being guided in a straight path by the claws. During the next half of the table movement, the saw moves in a semicircular path to align the next tooth of the saw with the claws which, during the last quarter of the table movement, guide the saw in a straight path towards the grinding wheel for the sharpening operation, the spring pressed clamp 3 and lever 10 permitting the saw to move relative to the table. The bracket 14 is adjustable by a spindle 15.
