Abstract: 1,039,786. Toy pistols. H. YANO. April 23, 1963, No. 15976/63. Heading A6S. In a toy pistol adapted to fire balls, the magazine chamber has a constructed region adjacent to the feed aperture to the discharge chamber to allow storage of a large number of balls without jamming in the feed aperture. The embodiment shown includes projections adjacent the feed aperture 4 of a shape which facilitate the passage of one ball at a time to the said aperture. Fig. 12 shows in plan view projections 9 and 10 of unequal length in one dimension, the elevation of such being shown in Fig. 13, which figure shows the final firing position 5 of the ball. Alternative arrangements of projections are shown in plan in Figs. 14, 16, 18 and 20, (not shown) and in elevation, respectively, in Figs. 15, 17, 19 and 21 (not shown). Fig. 3a (not shown) shows the firing mechanism, in which balls sequentially rest in the aperture 4 until the trigger 23 is pulled far enough back for the ball to drop into notch 24 of the said trigger. Further pulling of trigger 23 causes a projection thereon to pass through an opening 32 and the trigger to thus pivot about a pin 28, leaving the ball in the path of spring-loaded firing plunger 21, which is thus released. Spring 22 returns the trigger to its normal position.

Abstract: 756,047. Rectifying. TELEFUNKEN GES., [formerly TELEFUNKEN GES FUR DRAHTLOSE TELEGRAPHIE]. June 11, 1953 [June 11, 1952], No. 16075/53. Class 38 (2). [Also in Group XL (c)] The invention relates to saw-tooth current generating circuits of the type in which a damping diode in series with a H.T. boost capacitor is connected in parallel with an inductive circuit in the output circuit of a drive valve and in which voltage peaks occurring 'during the fly-back are rectified to provide a high voltage D.C. supply. In accordance with the invention an additional unilaterally conducted device is connected between a point of fixed potential and a point in the inductive circuit and arranged to be conducting during the long flank of the saw-tooth current to reduce the internal resistance of the high voltage D.C. source. Fig. 1 shows a circuit comprising a driver valve 5, a damper diode 3, deflection coil 4 and a E.H.T. rectifier 6. A further diode 8 is connected to a point in the inductive circuit to maintain that point at a substantially constant potential during the sweep in order to reduce the internal impedance of the E.H.T. source 12. The autotransformer shown may be replaced by a two winding transformer (Fig. 3, not shown), or may be omitted in which case the driver valve 25 (Fig. 8), feeds scanning coils 21 directly and provides an E.H.T. voltage through windings 26 and 31 the additional diode 40 is connected to a point 31 in the circuit or (Fig. 6, not shown), directly to the anode of the driver valve and serves to damp out ringing oscillation initiated during the fly-back. In the latter case the anode of the diode 40 is connected to the H.T. supply through a resistor (which may alternatively be an energy consuming device such as a focusing coil) and to earth through a capacitor. It may be arranged that energy stored in the capacitor is recovered. Specification 482,370, [Group XL], is referred to.

Patent GB-854925-A (GB)
Title: Improvements in or relating to phosphatide emulsifying agents
IPC: C09K23/00
Filed: 1957-05-22
Abstract: The invention comprises an oxyalkylated phosphatide, the phosphatide prior to oxyalkylation having an iodine number of from 30 to 60 and demonstrating a cloud point of not more than 60 DEG C. The oxyalkylated phosphatide may be obtained by treating a crude phosphatide to separate at least a portion of the hydrogenation catalyst poisons present, hydrogenating the separated phosphatide to an iodine number of from 30 to 60, e.g. by the process described in Specification 825,936, and then reacting the product with an oxyalkylating agent.  The phosphatide may be derived from lecithins, cephalins or sphingomyelins and particularly from crude soybean phosphatide.  Specified oxyalkylating agents are ethylene oxide, propylene oxide, butylene oxide, decene oxide, styrene oxide, epichlorhydrin, glycide, cyclohexene oxide and cyclopentene oxide. The oxyalkyation may be effected in any suitable solvent medium and an aqueous suspension of the phosphatide is suitably used.  The amount of oxyalkylating agent reacted with the phosphatide is preferably such as to raise the pH of a 5% aqueous W/V suspension to from 5,5 to 8,0 and more preferably to from 6,9 to 7,2.  Any excess ethylene oxide (when used) can be expelled from the reaction product by heating to about 80 DEG C. for about 20 minutes.  An example is given for the oxyethylation of a soybean phosphatide (iodine value about 52 and cloud point 32 DEG C.) in aqueous medium using gaseous ethylene oxide in such amount as to increase the initial pH of 5,8 to 6,7. Examples are also given in which cyclohexane or a mixture of cyclohexane and methanol are used instead of water as reaction medium in a similar oxyethylation process and a comparative example is included in which commercial soybean phosphatide is oxyalkylated with ethylene oxide.  The products are suitable as emulsifying agents in oil and water emulsions for parenteral administration (see Group VI). Specification 770,427 also is referred to.ALSO:A fat emulsion suitable for parenteral administration comprises an injectable trigylceride emulsified with water and containing as an emulsifying agent an oxyalkylated phosphatide (especially soybean phosphatide), the phosphatide (prior to oxyalkylation) having an iodine number of from 30 to 60 and demonstrating a cloud point of not more than 60 DEG C. (see Group IV(b)).  The injectable triglyceride is suitably a refined, edible coconut oil and a metabolisable carbohydrate e.g. glucose, and an anti-oxidant e.g. alphatocopherol may also be present. Specifications 770,427 and 825,936 are referred to.
