IPC: C11B1/00
Filed: 1926-08-03
Abstract: 257,582. Aktiesels:kabet Fors÷ksdrift. Aug. 31, 1925, [Convention date]. Fats and fatty oils, extracting.-In the extraction of the fat from blubber of whales and other marine animals a substantial proportion of the water contained in the blubber is removed by boiling the sub-divided blubber in vacuo before pressing out the oil. The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of atmospheric or higher pressure during the boiling, the removal of the oil from the partially dehydrated mass by centrifuging, pressing through a sieve, or other process, and the use of the apparatus shown. Using this device finely ground blubber is directed from a pipe 5 through a preheater 1 into a boiler 2 provided with a stirrer and smooth surfaces and heating elements, and a connection 6 to a vacuum chamber. When about 50 per cent of the contained water has evaporated the mass is discharged into a collector 3 and allowed to settle. The upper layer of oil is drawn off, and the layer of fibre dropped into a screw press. Dry clear oil results. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in devices for use in the prevention of fraud in cheques and the like
IPC: G09C1/04
Filed: 1933-07-06
Abstract: 413,867. Preventing alteration of cheques &c. RECHT, O. C., 129, Gothersgade, Copenhagen. July 6, 1933, No. 19214. [Class 16.] A device for use in preventing fraud in cheques and the like comprises a number of independentlymovable members each bearing one or more times the figures 0-9 in a non - arithmetic sequence. In one form, a number of rings b is freely rotatable in, but preferably non-removable from, slots cut in a base-plate a, knobs or apertures being provided in each ring to facilitate rotation. The rings are divided into twenty sections, each being provided with one or more of the figures 0-9. Alternate sections of the rings, or the figures therein are differently coloured or shaped, or are otherwise distinguished from each other, so that adjacent or other sections can be used for setting up a number and obtaining a cipher. In addition, some of the sections or figures are specially distinguished from the others to render fraudulent use more difficult. The device is provided with a fixed ring f also divided into twenty sections each furnished with an arbitrarily-chosen number. Outside the ring f is a plate g on which notes can be made for ready erasure. A pointer e is pivoted at the centre of the device and may be bent over the outer edge; the pointer may extend diametrically across the device and so serve to hold the rings in place. In other modifications, a double pointer, as indicated in dotted lines, or two independent pointers may be used. In use, a number is chosen as a code number, and the pointer e is positioned in register with the next square in an anticlockwise direction on the ring f to that containing the chosen number. Various figures from the number and amount of the cheque, as chosen by arrangement between the bank and the issuer of the cheque, are then set on the rings b adjacent the pointer e, and the figures in the adjacent sections, together with the control number, all of which may be indicated by the second pointer, are added together and inserted on the cheque, thus giving to the bank an indication of its validity or otherwise. In modifications, the rings b are replaced by longitudinally-movable slides co-operating with a fixed or movable bridge member, or the rings may be coaxially arranged on a core.

Screw propellers.-Relates to aerial propellers of the type described in Specification 136,003, and consists in alternative means for controlling and operating the adjustment of the blades and for indicating the adjustment. The propeller shaft A, Fig. 1, terminates in a tubular T-shaped hollow member A' in which are mounted the concentric pivots B, C, each carrying one of the blades. The pivots are angularly adjusted during rotation by means of the lever B<21>, C<21> engaging in the helical groove D' in a drum D. The drum D is supported on an axle D<2> carrying a worm wheel D<4> which is rotated by a worm E' mounted on a shaft E. The other end of the shaft E carries a chain wheel E<3> which is driven by a chain from the chain wheel H' mounted on the shaft H passing through the propeller shaft A. In an alternative arrangement Fig. 3, the shaft H passes through the pivots B, C, the chain wheel H' being carried at its outer extremity. In another form, the shaft H is arranged parallel to the shaft A and a sleeve carrying a chain wheel and gear wheel is freely mounted on the shaft A. The sleeve is driven from the shaft H, and drives the shaft E by gearing. The apparatus for operating the shaft H to vary the pitch of the blades and to indicate the pitch is shown in Fig. 6. The shaft H terminates within a gear box K and carries a pinion H<2>, while the propeller shaft A carries a pinion A'. A shaft N carries a bevel wheel R and a pair of transverse pins P' on which bevel wheels P<2> are freely mounted are carried by the cage P. These bevel wheels mesh with another bevel wheel S which is freely mounted on the shaft N and carries a pinion S<1> meshing with the pinion H<2>. A pinion P<3> is mounted on the cage P and meshes with the pinion A<5>. The operating handle M is normally stationary for any given setting of the blades and the shafts A and H therefore rotate as one, the latter through the .gearing. When the handle M is rotated, the wheel R moves with it and causes a relative movement between the shafts A and H which alters the blade setting. The shaft N carries a worm N<1> gearing with a worm wheel T which carries an-indicating pointer T<1>.

IPC: C10G32/02
Filed: 1934-07-02
Abstract: In a process for separating wax, asphalt and similar impurities from oils, the impurity is precipitated in the oil and the resulting mixture is submitted to an electric field, and finally the coagulated impurities are separated from the oil.  Crude lubricating oil passes from a tank 10 to a chiller 20 where it is mixed with a light hydrocarbon diluent and shock-chilled to precipitate the wax in the oil.  The mixture is then pumped into a chamber 25 provided with a high voltage electrode 27, the container forming the second electrode.  The wax is precipitated and removed through a pipe 34, and the upper layer of oil containing some wax is pumped into a tank 50 in which the remainder of the wax settles, and the waxfree oil is then freed from solvent in a still 60.  The dewaxed oil is drawn off into a tank 65, and the solvent vapours are condensed and returned to a tank 11.  If desired, the wax precipitate and some oil is drawn off <PICT:0442429/III/1> through the pipe 34 and passed directly to the filter press 47, or forced into the chamber 50 for further settling, the supernatant oil containing some wax being treated in a centrifuge or the filter press 47, and the filtrate is then distilled.  A battery of electrical treating chambers 25 may be used and provided with scrapers for removing the wax.

Abstract: 420,658. Liquid-meters. ETABLISSEMENTS POMPES GUINARD, Chemin de la Fouilleuse, St.-Cloud, Seine-et-Oise, France. July 3, 1934, No. 19559. Convention date, July 4, 1933. [Class 69 (ii)] The moving member of a liquid-meter is connected to a totalizer graduated in weight units through a variablespeed transmission, controlled from a balanced float immersed in the liquid to be metered, so that density variations are compensated. The float controls the transmission through a hydraulic, electric, or mechanical servomotor, and the indicators are duplicated, one or the other being operated depending on the direction of flow through the meter. The float 9 may be balanced by a lever having perpendicular arms and weighted at 14, by a cam and counterweight, or where latitude effect is disregarded, by a spring. The servomotor has connected pistons 16, 17, and its cylinder ends are connected under the control of a distributing valve 22 with pipes 19, 20 leading from the main conduit on opposite sides of the meter 1. A valve 30 operated by a diaphragm 35 ensures that the higher pressure liquid may always be admitted to the correct end of the servomotor cylinder irrespective of the direction of flow through the meter. The moving part of the meter operates an instantaneous flow indicator 62, a volume totalizer 66 and through a connecting rod 46 and ratchet gearing the totalizer 5. A stop 61 adjusted by the movement of the servomotor through a lever 55 limits the return stroke of the pawl-carrying lever 51, a spring 47 allowing the connecting rod 46 to telescope as required. When the liquid being metered is of a predetermined density, the lever 55 engages a coupling 68 for driving a volume totalizer 67 and makes a contact at 69 for an electrical signal 70. When the direction of flow through the meter is opposite to the arrow 37, the pinion 42 carried by an arm 41 frictionally mounted on the pinion 40 is moved to mesh with a pinion 44<1> for the operation of the duplicate set of totalizers 5<1> &c.
