Title: Improvements in or relating to detergent preparations
Inventor: ALSBURY ALLAN
IPC: C11D10/04
Filed: 1957-07-15
Abstract: Compositions containing fatty acyl aminomethane sulphonates and soap are made by a process in which fatty amides are reacted with 0.8-1.5, preferably 0.9-1.2, molecular proportions of sodium or potassium formaldehyde bisulphite in the presence of soap and free fatty acid, the free acid being subsequently neutralized.  The fatty amide, fatty acid and soap all preferably contain 10-18 carbon atoms and the fatty acid and soap are suitably derived from the mixed fatty acids of palm, palm kernel, coconut, cottonseed, or groundnut oil, or from tallow or bone grease; the amide is preferably derived from palm-kernel or coconut oil.  The amount of fatty acid present is 15-40% by weight of the fatty amide, and the amount of soap is at least 1% of the weight of the amide but is not more than the amount by which the fatty acid present exceeds 14% by weight of the amide. The reaction is carried out in an inert atmosphere at 150-210 DEG C., preferably 170-190 DEG  C., and the mixture remains fluid throughout the process, after which it is fully or partially neutralized, for example with sodium carbonate or hydroxide.  If preferred, however, the soap may be present as an ammonium or organic base salt, such as the dicyclohexyl-ammonium salt, or as the salt of another alkali metal.  After being neutralized, the composition may be purified by adding additional soap, dissolving or slurrying with hot water and graining it out by the addition of brine.  The grained-out mixture will contain some salt, the deleterious effects of which may be counteracted by the addition of a small amount of sodium toluene or xylene sulphonate.  The compositions may be made up into tablet form, particularly if some unconverted fatty amide is present.

Abstract: 1,154,353. Photographic cameras. EASTMAN KODAK CO. July 12, 1966 [July 12, 1965], No.22352/66. Heading G2A. A photographic camera having a rotatable socket to detachably receive a flash-cube is provided with means to rotate the socket and an inserted flashcube during exposure so as to sweep the ignited lamp across the camera exposure axis. A flashcube is inserted in the socket 23 and as described in (Specification 1,154,352), is held therein by retaining springs, an attachment of the flash-cube being used to adjust the camera mechanism for flash operation. The socket is tensioned for rotation by means connected with the film wind and shutter described in (Specification 1,154,352). Fig. 2 shows the ready for exposure position. As a body release member 31 is depressed an extension 121 thereof engages an ear 122 of an indexing lever (114, Figs.3, 4, not shown) to clear a tab 115 from a notch of the socket 23. While the member 31 is fully depressed a shutter striking plate 36 is spring urged anti-clockwise (as seen) to open the shutter, movement of the plate 36 allowing a lever 107 to rotate out of engagement with a ring (100) which forms part of the socket rotating mechanism. The socket is thus free to rotate clockwise (as seen) until the lug 125 of a laterally displaceable and pivotable arm 123 engages the next notch and is fully displaced to the left (as seen in Fig. 2). The socket will then have rotated through 90 degrees. As the member 31 rises, the tab 115 is urged into the notch occupied by the lug 125 which is thereby displaced and moved back to the right, to take up the position shown.

Abstract: 673,102. Time switches. METROPOLITANVICKERS ELECTRICAL CO., Ltd. Aug. 15, 1950. [Aug. 31, 1949] No. 22620/49. Class 38 (v). A time switch for determining the duration of a manufacturing or other process has two rotatable striker members which are jointly effective to unlatch a switch at the end of the time interval, one of the members being driven at a fractional speed relative to the other. The switch has a drive motor 10, Fig. 1, which through a spring controlled friction clutch 17 and pinions 16, 18, 24, 36, 37 drives sun wheels 25, 35 of a differential gear, the sun wheels being freely rotatable on a shaft 26 to which is rigidly fixed the axle 33 of planet wheels 34. A plate element 40 of a friction clutch is secured to the shaft 26 and has depressions 43, Fig. 2, engaged by a bowed spring member 41 which may be set by a knob 3 and carries the striker member 61, Fig. 2. The other striker member 60 is carried by a pinion 48 driven by a pinion 44 on a shaft 21 driven by the motor through the pinions 16, 18. A knob 4 and pinion 45 permit the setting of the member 60 away from a zero position. In the arrangement shown, the gearing provides a 60 : 1 ratio between the "minutes" striker member 61 which is turned through one revolution in an hour, and the "seconds" striker member 60 which makes one revolution in a minute. In use, the knobs 3, 4 are turned to set the desired time interval in minutes and seconds which is indicated by pointers 5, 6 carried by the knob 3 and pinion 48 respectively. This moves the striker members 60, 61 away from the zero position indicated. in Fig. 2. A knob 12 on a shaft 11, is then depressed to close a microswitch 13 to initiate the process and to start the motor 10. The shaft 11 is latched down by a bar 50 which is biassed by a spring 52 into a slot 53 in the shaft 11. The bar 50 is provided with a pivoted lever 54 which co-operates with pins 56, 57 on the striker members 60, 61. At first, as the "seconds" striker member 60 passes through the zero position its pin 56 in engaging with the lever 54 merely pivots the lever 54 against the tension of a spring 55 as indicated in Fig. 4. This action is repeated as the member 60 rotates, on each subsequent revolution, 'until towards the end of the set period the pin 57 on the "minutes" striker member 61 engages the lower end of the lever 54, then as the striker member 60 moves into its zero position its pin. 56 in engaging the lever 54 causes the lever to pivot about the pin 57, so withdrawing the bar 50 and unlatching the shaft 11 to open the switch 13. In a modification, Fig. 6 (not shown) the differential gear arrangement is provided with friction clutches and brakes so that shaft 26 may be driven at any one of three different speeds. In Fig. 7 (not shown) each sun wheel has its own drive motor, the motors being selectively energized to provide the desired speed.
