Title: Improvements in or relating to mnemonic devices for use in connection with machines or motor vehicles
IPC: G08B5/30
Filed: 1933-06-13
Abstract: 417,146. Indicating and signalling devices. CASSAN, J. H. F., 16, Avenue d'Orleans, Paris. June 13, 1933, No. 16890. Convention date, June 14, 1932. [Classes 106 (i) and 106 (iii).] An indicating, or warning device for reminding an operator when certain operations fall due, such as the lubrication of machine or vehicle parts, comprises a rotatable member adapted to be driven in accordance with the movements of the member to be supervised and having on its periphery differently coloured sectors, the degree of intensity of a certain colour indicating the degree of urgency of the operation to be effected. The device has means for preventing further operation of the member on the completion of a predetermined displacement whereupon the signal is given, and manually operable means are provided to effect the resetting of the member to operative condition. In certain cases the operation to be performed must be completed before the member can be restored to initial position. As shown in Fig. 1, as applied to vehicles the time and distance registering shafts 7, 8 transmit their movement through a differential gear 9 to an eccentric operatively connected to a pivoted arm 12 carrying a pawl 14 driving a ratchet disc 15 integral with an indicating drum 3 bearing coloured sections, or other signs viewable through an aperture 2 in a cover plate 1. When the drum has rotated a predetermined amount from an initial position, determined by a stop 18 thereon and fixed abutment 19, a mutilated portion of the ratchet disc 15 is presented to the pawl 14 to arrest its movement. At this moment the stop 18 closes contacts 21 to complete the circuit of a signal lamp 6 or other warning device. By the operation of a push button 5 a member 22 is rocked about its pivot 23 to throw out the actuating pawl 14 and a retaining pawl 16 whereupon the indicating drum 3 is returned to its initial position under the action of a coil spring 17. In a modification shown in Figs. 3 and 4, the drum 3 is actuated by a worm gearing adapted to be clutched to a driving shaft 28. When the clutch is freed by the action of the stop 18 on the levers 32, 33, another clutch is rendered effective to drive a delay indicator 3<1>. To zeroize the drum 3 it is slid along its axis by operating the button 5 as shown in Fig. 4. The interlocking of the device with a lubricating cap is shown in Fig. 5. The movement of the tap 40 to its open position through a linkage 41 sets a slide 44 to free the push button 5 for operation.

Title: Self-wringing mop
IPC: A47L13/14
Filed: 1948-06-24
Abstract: 661,388. Self-wringing mops. WEGER, K. June 24, 1948, No. 17044/48. Class 19. A self-wringing mop of the kind shown wherein a scrubbing.cloth or like mopping material 2 is held in working position by two clamping elements 4, 15, one mounted rigidly and the other swingably on the end of a handle 1, the mopping material being drawn up between the closed clamping elements, Fig. 2, to be wrung put and the swingable clamping element 4 then being swung away from the: fixed element 15 and subsequently swung back again to allow the mopping material to pass down to and thereafter be .held in its original working position, is characterised by the provision of two lever systems, one for moving the swingable clamping element 4 and the other for moving the mopping material, and means for actuating each of said lever systems, said actuating means being in positions adjacent to each other when the mopping material is in its working position. In the mop illustrated, the lever system for moving the mopping material comprises a throw-over lever 11 which is pivoted on the handle and has an actuating handle 12 provided with a V-shaped rod 10 whose ends are fastened to the top edge of fringed cloth mopping material 2. Clamping element 15 may be a roller but preferably is in the form of a crosscleat secured to the end of the handle 1; it is overlaid by the beaded flange 3 of a guide cage 5 through which the mopping cloth is drawn up in the wringing operation. The swingable clamping element 4 is a roller rotatably supported in one arm of a bifurcated lever 6 pivoted on pins 7 on handle 1, the other arm of said lever 6 being connected to one end of a tension spring 8 whose other end is attached to a stretcher lever 9. Upward movement of lever 9 turns lever 6 whereby the clamping element 4 is moved to the closed position. In use, the throw-over lever 11 is positioned as shown in Fig. 1 with the roller 4 in the closed position; then handle 12 is swung upwards to draw the mopping material between the closed clamping elements in the wringing out operation (Fig. 2). To restore the mop to the working position, stretcher lever 9 is swung downwardly to unclamp the swingable clamping element 4, whereupon throw-over lever 11 is also swung downwardly, thus putting the mopping material in working position (Fig. 1) and finally the clamping elements 4, 15 are closed by upward movement of stretcher lever 9. Automatic release of stretcher lever 9 following the wringing operation is effected by means of an extension 13 on throw-over lever 11; when lever 11 is pulled down to restore the mopping material to working position, the extension 13 releases stretcher lever 9 (Fig. 2) whose downward movement is then maintained by tension spring 8 whereby roller 4 is swung out and the mopping material unclamped. In addition to the cage 5 additional guiding means for the mopping material are provided by arms 14.

Abstract: 319,228. Spence & Sons, Ltd., P., and Crundall, S. F. W. June, 14, 1928. Calcium sulphate.-An extremely finely divided and apparently amorphous form of anhydrous calcium sulphate is obtained by treating hydrated forms thereof with suitable dehydrating agents. The hydrated salt may be mixed with sulphuric acid of specific gravity 1.6-1.84 and the mixture be maintained at 130‹ C. with agitation for say 1-2 hours, or be gradually heated to 140‹ C., or be allowed to stand at ordinary temperature for several days, or be maintained at 100‹ C. for the necessary time. The specific gravity of the sulphuric acid used should not fall below 1.3 during dehydration and the strength, quantity, and concentration thereof should be such that no solution of the sulphate or substantial formation of soluble acid sulphates occurs. The anhydrous sulphate is washed free from acid and dried, or dried and calcined. Dehydration may also be effected by fuming sulphuric acid at ordinary temperature, or by passing dry sulphur trioxide over the hydrated salt, and phosphoric acid or acid sulphates such as titanium sulphate may be used as dehydrating agents. According to the Provisional Specification, the hydrated salt may first be dissolved in concentrated sulphuric acid at say 140‹ C., and the anhydrous salt be then precipitated by dilution; or a mixture of hydrate and sulphuric acid be heated and then calcined; and phosphoric anhydride or glycerin may be used as dehydrating agents.

Title: Manufacture of alkaline-earth metal compounds of the organic phosphorus compound contained in milk casein
IPC: C07K14/78
Filed: 1923-07-04
Abstract: The alkaline-earth metal compounds of the organic phosphorus compounds contained in milk casein are prepared by digesting the casein with weakly ammoniacal trypsin until the fatty acids and their compounds separate, and either precipitating directly the alkaline-earth compound in presence of alcohol, or first precipitating with a heavy metal salt, removing the heavy metal, neutralizing the solution and precipitating the alkaline-earth compound as before.  In an example commercial milk casein is digested with ammoniacal trypsin or pancreas and the solution, after filtration and clarification with diatomaceous earth, is precipitated with calcium chloride or acetate and alcohol. Another example shows the precipitation with basic lead acetate or mercuric chloride, the removal of the heavy metal with for example sulphuretted hydrogen or sulphuric acid and the subsequent precipitation of the calcium compound.  The latter may in each case be washed with alcohol or dissolved in water and precipitated by alcohol, filter-pressed, dried in a vacuum and pulverized.

Title: Improvements in and relating to magnesium-base alloys
IPC: C22C23/00
Filed: 1946-06-13
Abstract: A modification of the magnesium base alloy of the parent Specification consists of 1-13 per cent Li, 1-10 per cent Zn, and one or more of the metals Al from 0.5-8 per cent, Cd from 1-10 per cent, Ag from 1-10 per cent, and the balance Mg, the lower limit of Li being 3 per cent when Al but neither Ag nor Cd is present.  The alloys may be prepared by melting the magnesium under a flux of one part lithium fluoride and three parts lithium chloride, adding the zinc, silver, cadmium or aluminium and finally the lithium.  The said flux is said to reduce the sodium or potassium content of the alloy to 0.1 per cent or less; blowing the melt with nitrogen or ammonia further helps in this respect. To ensure clean flux/metal separation, the flux may be thickened by the addition of molybdenum sesquioxide, vanadic acid, magnesium oxide, or boric anhydride.
