Abstract: 510,549. Prepayment mechanism for meters. UNITED GAS INDUSTRIES, Ltd., SMITH, E. W., and CHARLES, A. Feb. 8, 1938, No. 3913. [Class 27] In prepayment meter mechanism, when the maximum allowable number of coins at a time has been inserted, a stop member is moved into the return push of an element of the coin holder to lock the coin holder substantially in the coin-discharging position after discharge of the last coin, until sufficient commodity has been consumed to release the stop and allow the coin holder to be returned for further prepayment. As applied to the coin-holder mechanism described in Specification 400,636 with transmission mechanism as described in Specifications 387,678 and 392,530, a cam c on the valve control element d actuates an arm e on a spindle f to cause a second arm g to move a pawl a through an opening in the coin holder casing b at the moment the coin holder is in alignment with the coin discharge slot in the casing. The pawl a, which is pivoted at a<1> inside the casing b, is engaged. with the striker that is moved by the lower value coin and prevents return of the coin holder to coinreceiving position. The pawl a is double-ended, one end acting as the coin-holder stop and the other operating to prevent backward rotation of one of the quantity wheels. In a modification, Fig. 4, instead of a pawl, a plunger i is moved into the casing against the action of a spring i<1> by an arm k on the spindle f.

Abstract: 700,091. Centrifugal and screw fans. BARKER, D. R., and BARKER, W. H. April 17, 1951 (Feb. 16, 1950], No. 3998/50. Class 110 (1) In a ventilating fan, a closure plate 7, Fig. 1, slidably mounted on the impeller shaft 2, is pressed by spring means in a closing direction to interrupt the passage of air through the impeller 1 and is slidable into the open position shown dotted mainly or solely by the force of the air passing through the impeller, the spring means being caused to yield when the fan is running. Each spring means is made of spring wire shaped to provide a loop 13, Fig. 3, which engages in a groove in the periphery of a governor weight 10. Legs 15, which are inclined to the plane of the loop 13, fit into slightly inclined holes in the periphery of the impeller hub 12. When the fan is running, the weights 10 take up the positions shown dotted in Fig. 1 under centrifugal force, and the legs 15 are constrained into a different angular position relative to the spring arms 11. The resultant twist applied to the arms 11 causes the spring means to flex back to their original positions when the fan is stopped. The plate 7 is then held against a cork wasner 8 so as to seal the impeller inlet opening. The hub 12 may have a conical seating which engages a conical face on the hub 16 of the plate 7 so as to centralize the latter in the fully open position. The hub 16 'is of rubber, felt or graphite-impregnated plastic. The plate 7 may be of conical shape. In a modification, the impeller is of the axial-flow type, with radial blades attached at their tips to a shroud ring. In this case, the plate 7 is situated at the outlet side of the impeller.

Title: Method for recovering bitumen contained in peat
IPC: C10C3/08
Filed: 1947-02-12
Abstract: Partially-dried bituminous peat is extracted with a mixture of organic solvents, including solvents which are soluble and insoluble in waters, and are capable of forming azeotropes either mutually or individually with water, the solvents being used in such proportions to each other and to the extracted-water that, on distillation of the extract, the azeotropes escape as vapour leaving one solvent only, preferably the water-soluble one, containing the extracted bitumen. The extracted bitumen may be subjected to further treatment in the form of the solution or dispersion so obtained.  The peat-to-be-extracted preferably contains 5 to 35 per cent of moisture, and is in the form of grains of 1 to 3 mm. in size. Solvent mixtures referred to are alcohol-benzene, and alcohol-trichlorethylene.  The peat may be extracted while it is still warm from the preliminary partial-dehydration step, and the mixture of solvents used may also be heated.  The yield of bitumen is augmented by treating the peat, during or after grading, with a dilute solution of an acid, e.g. 1 to 5 per cent hydrochloric acid, followed by drying.  The acid-treatment may also be carried out in connection with the extraction.  Specification 469,352 is referred to.

Title: Improvements in sharpeners for slicing machines
IPC: B24B3/46
Filed: 1920-02-11
Abstract: 138,909. Berkel, C. F. M. van. June 4, 1917, [Convention date]. Machine cutters, sharpening in situ.-Relates to a sharpening- device for the knives of slicing - machines, and comprises a sharpener in which means are provided for preventing the grinding-wheels from being brought into and out of the sharpening position in contact with the blade other than by movement directly towards and from the lateral faces of the blade. The sharpener comprises a casing 5, in which are mounted two spindles 7 carrying grinding-wheels 8 adapted to be moved, in the direction of their axes, into and out of contact with the blade 13 by means of a cam 10 operatively rotatable by means of a handle 11 extending through the wall of the casing; the grinding- wheels are moved towards the blade by springs and away therefrom positively by the cam. The casing is carried by a standard 3 slidable in the bored end of a post 1 secured to the frame of the machine, its lowest position, Fig. 3, corresponding to the position of the grinders opposite the edge of the blade, being determined by an adjustable screw 4. When in this position, a notch 21 in a lever 14, pivoted at 15 to the casing and acted upon by a spring 16, engages the bevelled periphery of a disk 19 secured to the post 1, and, the lever 11 being moved to bring the grinders into contact with the blade, the casing cannot be raised owing to the contact of a bearing foot 22 of the lever with the lateral face of the cam, which prevents disengagement of the notch from the disk. In order to raise the grinders, the cam must be rotated to remove these laterally from the blade, such rotation bringing an opening 25 in the cam opposite the foot 22, and thus allowing movement of the lever 14 by the operator to disengage the notch from the disk, whereby the casing is free to be raised. When in the raised position, the grinders cannot be moved to approach the blade owing to the engagement of the foot 22 with a flat shoulder 30 at one side of the opening 25 in the cam, which prevents rotation thereof; the casing may be maintained in the raised position by means of a pin 26 thereon, which is adapted to rest on the disk 19, and a hole 27 in this permits of the lowering of the casing and also serves to position it during such lowering. A depression 28 in the disk assists in locating the casing in the inoperative position with the grinders turned away from the knife.
