Title: Toy
IPC: A63H27/04
Filed: 1972-08-18
Abstract: 1405938 Toy aeroplanes, &c KUSAN INC 18 Aug 1972 [20 Aug 1971] 38645/72 Heading A6S A toy comprises in combination a support line having means for securing a first end of the line at a certain height, a control means connected to the second end of the support line and capable of varying the tension or sag in the support line, a toy aeroplane including an aeroplane, support arranged to slide along the support line while supporting the aeroplane from the line, and a launcher arranged to propel the aeroplane along the support line in a forward direction. As shown, a toy aeroplane 300, Fig 8, is suspended from a line 24 by a single hook 318 which is skewed relative to the main axis of the aeroplane, Fig 10. An elastic catapult 324 is provided on a take-off and landing plate 302. A post 54 securing one end of the line 24 is clamped above the take-off &c plate 302. The other end of the line 24 is secured to a post 114 (see also Fig 5) on a slidable shaft 108 in a control unit 26 simulating the cockpit of an aeroplane. A steering wheel 112 allows the shaft 108 both to be turned and to be slidden axially. The toy aeroplane has a rudder 314 so inclined that the twist imposed on it by the skewed arrangement of the hook 318 is. aerodynamically opposed when it is catapulted up the line 24. The aeroplane 300 thus proceeds nose-first up the line 24. When the aeroplane 300 finally comes to rest, the skewed hook 318 causes it to turn through 180 degrees, with its nose pointing down the line 24. The toy aeroplane then slides back down the line 24 to land on the take-off &c plate 302. During both directions of flight, the aeroplane is controlled from the steering wheel 112. Pushing, &c the steering wheel 112 slackens, &c the lines 24, and allows control of the speed of movement of the aeroplane 300. Turning the steering wheel 112 causes the post 114 to tilt, moving the line 24 sideways so that the aeroplane simulates a turning movement. A know form, Fig 1, omits the catapult, the aeroplane 32 being suspended by two hooks 46, 48 from the line 24 hung between a post 22 clamped to a table, and the control unit 26 described above. The post 22 carries a reel 28 upon which the line 24 is wound for storage, and a catch 60 engageable by the elevator tail control (40), Fig 2 (not shown), of the toy aeroplane 32. To use the toy, the line 24 is slackened and the aeroplane 32 is slidden backwards up the line 24 to engage its tail elevators (40) with the catch 60 on the post 22. The aeroplane 32 is then suspended by its tail with its nose pointed downwardly. The control wheel 112 of the control unit 26 is operated to tighten the line 24, when the aeroplane is automatically pivoted up and thus released from the catch 60 to slide down the line 24. In another method of using this known form, the control unit 26, Fig 7, is placed upon a table 102, and the other end is tied to a chair leg 200. At the start of a flight, the aeroplane 32 is placed upon the table 102. When the control unit 26 is operated to tighten the line 24, the aeroplane is lifted off the table and slides down the line 24.

Abstract: 1,019,185. Temperature responsive actuating elements. GENERAL MOTORS Ltd. Sept. 17, 1964 [Oct. 3, 1963], No. 38933/63. Heading G1D. A thermo-responsive power device 2 of the kind in which a pin 37 moves axially in response to volume changes in a body of micro-crystalline wax within a casing 51, the pin 37 moving inside a rubber sleeve, is calibrated by heating it to its actuating temperature and then reducing the taper of a frusto-conical portion of the casing 51 and thus its volume until the pin extends the desired distance from the casing 51. This reduction in the volume of the casing is effected by means of four collet jaws 1 secured to four radially moving slide blocks 5. These are moved by cam plates 15 attached to a carrier 10 vertically reciprocable on a member 3 by a power actuated arm 11. In operation the device 2 is heated to the desired temperature and placed in between the collet jaws. 1. A housing 29 is lowered on guide bars 23 until a spring loaded sleeve 32 engages the housing 51 and a spring loaded spindle 33 engages the end of the pin 37. The carrier is moved downwardly causing the collet jaws 1 to compress the housing 51 and the pin 37 to extend therefrom moving the spindle 33 upwards. The spindle 33 is connected to a pin 41 extending transversely thereto and adapted to operate a switch (not shown) stopping further movement of the carrier 10. Operation of the switch is arranged to occur when the pin 37 extends the desired distance from the housing 31.

Title: Improvements in or relating to the production of heterocyclic compounds
Inventor: ASH ANTHONY STANLEY FENTON
IPC: C07D209/20
Filed: 1957-12-18
Abstract: The invention comprises a process for the preparation of indole derivatives of the general formula:  <FORM:0845034/IV(b)/1> (wherein R is an alkyl or aralkyl group, R1 and R2 are alkyl groups containing at most 4 carbon atoms and R3 is a hydrogen atom or an alkyl group containing at most 4 carbon atoms) in which a di-lower alkyl a -acylaminomalonate is added to acrylic aldehyde to produce a 3:3-di-(carbalkoxy) - 3 - acylaminobutyraldehyde, this is condensed with a 4-alkoxy- or 4-aralkoxy-phenyhydrazine and the 4-alkyl- or 4-aralkyl-phenylhydrazone is cyclized with elimination of ammonia. The addition process is advantageously effected by heating equimolecular proportions of the reactants at less than 45 DEG C., the formation of the phenylhydrazone is preferably carried out at an elevated temperature using equimolecular proportions of the reactants and the final cyclization is desirably effected with sulphuric acid, boron trifluoride or zinc chloride, and most desirably with excess sulphuric acid at an elevated temperature. The intermediate products in the above process need not be isolated, and all the reactions may be carried out in a nuclearly-chlorinated aromatic hydrocarbon, such as chlorobenzene or o-dichlorobenzene or a mixture thereof.  The above process may be combined with a process for the preparation of 5-hydroxytryptophan, by converting the indole derivative of the above general formula into 5-hydroxytryptophan by known methods of hydrolysis and decarboxylation of substituted malonic esters, followed by hydrolysis (where necessary) of the acylamino group and reductive fission of the group R by known methods.  If R3 is a hydrogen atom the formylamino group is hydrolysed simultaneously with the ester groups R1 and R2.  An example describes the preparation of ethyl a -acetylamino-a -carbethoxy-,b -(5-benzyloxyindolyl-3) -propionate and the conversion of this to 5-hydroxy-tryptophan via a -acetylamino-a -carboxy - b  - (5-benzyloxy-indolyl-3)-propionic acid, a -acetylamino - b  (5-benzyloxy-indolyl-3)-propionic acid and 5-benzyloxytryptophan.  4-Alkoxy- and 4-aralkoxy-phenylhydrazines are prepared by diazotizing the appropriately substituted anilines and reducing the resultant diazo compounds.  The preparation of 4-benzyloxyphenylhydrazine hydrochloride is described.  In the Provisional Specification this compound is prepared by diazotizing 4-benzyloxyaniline hydrochloride, reacting the product with sodium meta bisulphite, sodium acetate and sodium hydroxide to form sodium 4-benzyloxyphenyl diazonium sulphonate, reducing this with zinc and acetic acid to the hydrazosulphonate and hydrolysing this with ethanol and hydrochloric acid.

Title: Improvements in or relating to the production of dispersions
IPC: C09K23/00
Filed: 1958-12-17
Abstract: A dispersion including an internal and external phase is produced by vacuum depositing material of the internal phase on to a matrix consisting of an organic plastic material presenting a large surface area, and then blending the internal phase and matrix material together with any additional components of the external phase.  The vacuum deposition is effected by evaporation or cathode sputtering, and the matrix material may be in powder or sheet form.  Where the matrix material is to constitute the external phase exclusively, the dispersion may be produced from the coated matrix by moulding under heat, or casting, spraying or flowing from solution.  Where other materials are included in the external phase, the coated matrix material may be dissolved in a solution containing such materials. In a modification, where the matrix material is not to be a component of the external phase, the coated matrix material may be dispersed in the external phase and the matrix material then removed.  The invention is particularly described with reference to products used in photographic transfer reversal processes (see Group XX). Specifications 684,592, 714,412, 751,304, 789,837 and U.S.A. Specification 2,774,667 are referred to.
