Filed: 1932-06-20
Abstract: 386,226. Centrifugal machines. KRAUSS, F. E., Schwarzenberg, Saxony, Germany. June 20, 1932, No. 17451. Convention date, June 18, 1931. Addition to 338,421, [Class 23, Centrifugal machines &c.] [Class 23.] The centrifuge described in the parent Specification and particularly adapted for washing purposes, has a drum d mounted yieldingly in directions transverse to the axis. The drum has vanes e, Fig. 1, and is driven by the air current from the fan f on the motor g. The rounded bearing pin d<1> of the drum rests on the column c. The shaft i can slide but not turn in the lid k, and is supported by rubber rings l, l<1>. The pin i<1> at the end of the shaft i passes through a hole in a conical casing h in the drum, and the sleeve m on the shaft i is attached to a friction. cone n over the conical casing h. The drum can move laterally on the bearing column c owing to the clearance between the conical members h, n. If the swing becomes too large, the drum is braked by the engagement of the cone h inside the cone n. The resistance of the rubber rings l, l<1> also increases as the swing of the drum increases. The cone n can be used as a hand brake by depressing the ball i<11>. The lid k may be held in a yielding manner by arms o of rubber or like material, with claw members such that the lid can only be put on after a certain resistance has been overcome. The braking of the drum can also be effected by a braking cone s<1> being forced into contact with the brake band s by the operation of a lever t<11>. The Specification as open to inspection under Sect. 91 comprises also a modification in which the drum is driven through the cone n by the shaft i and oscillation is taken up by the resilient mounting l, l<1>, and another modification in which the driving motor p, Fig. 4 (Cancelled), has a flange p<1> which is supported in a rubber ring l<11> in the lid k. This subject-matter does not appear in the Specification as accepted.

In a system for checking that a number of couplings, e.g. hose couplings, have been correctly made, one member of each coupling is connected to means for generating a train of pulses of number characteristic of that particular coupling, the other member being connected to apparatus responsive to the pulse trains for indicating the number, the two members of each coupling having means for conducting or transmitting the pulses when a coupling is made. The couplings C are selected in turn by an address register 11 which counts from 0 to 19, and at each count the address decoder 17 opens a corresponding gate 18 to allow the pulse train to pass to the coupling. The pulse trains are derived from a counter register 12 which repeatedly starts from zero and counts up to the number in the address register. A comparator 13 comparing the count in the address register with that in the counter register gives a pulse when equality is reached to step the address register on to the next value and to reset the counter register to zero. The pulse trains are counted in the indicator registers 14 and the associated display should show a number equal to the number of the corresponding hose assembly. Means may be provided to give an audible or visual alarm when a coupling has been wrongly made.

Title: Improved process for regenerating spent fuller's earth
IPC: C11B13/04
Filed: 1949-07-12
Abstract: Spent Fuller's earth containing oils, fats, waxes, colouring matter &c., is regenerated by extracting it with a solvent consisting of petroleum spirit or another volatile hydrocarbon of the non-aromatic type until the bulk of the solvent-soluble substances have been removed, and then introducing water or steam into the residual material soaked with the solvent used, adding fresh solvent of the same kind and heating nearly to the boiling point of the solvent used.  The first extract is pale in colour and contains mainly the bleached substances; the second extract is dark and contains the colouring matter; this extract is decanted as a supernatant layer. The Fuller's earth is then freed from solvent and fully reactivated, if desired, by the usual acid and calcination treatments.  The spent Fuller's earth treated may be a mixture with other decolourising materials such as carbon; excessive moisture may be removed therefrom by drying prior to extraction.  Specication 526,237, [Group VI], is referred to.
