Title: Synthesis of pantothenic acid-4 phosphate
Inventor: BADDILY JAMES
IPC: C07C233/46
Filed: 1950-12-04
Abstract: Pantothenic acid-41 phosphate is obtained by reacting 3:3-dimethylbutyro-g -lactone with an alkali metal or an alkoxy derivative thereof, condensing the metallic derivative of pantolactone thus obtained with an aralkyl halide to form an aralkyl ether of pantolactone, condensing the pantolactone aralkyl ether with an ester or alkali-metal salt of b -alanine, the NH2 CH2 CH2- of the b -alanine being unsubstituted, phosphorylating the resultant pantothenic acid derivative with a diaryl halogeno-phosphonate to form a diaryl-phosphate of pantothenic acid, treating the diaryl phosphate to remove the aryl groups and isolating pantothenic acid-41 phosphate.  Preferably the pantolactone is reacted with sodium ethoxide, phosphorylation is effected by means of diphenyl chlorophosphonate and the aryl groups are removed from the diaryl phosphate of pantothenic acid by hydrogenolysis or alkaline hydrolysis.

Filed: 1967-06-28
Abstract: 1,129,780. Electrically-operated toy vehicles on tracks. R. FUKUDA. 28 June, 1967 [1 April, 1967; 31 May, 1967], No. 29740/67. Heading A6S. An electrically driven wheeled toy comprises a chassis 2, a group of wheels 1L, 1R, 19L, 19R including at least a pair of driving wheels 1L, 1R rotatably mounted on the chassis through driving shafts 7L, 7R supported on differential gear 6 and carrying rotary plates 8L, 8R, a driving mechanism such as a motor, M1, reduction gears 3L, 3R, clutch mechanisms 4L, 4R and transmission shaft 5 driving the driving wheels, a controlling mechanism 9 controlling the operation of the driving mechanism, an electrically-sensitive means 10, provided with a plurality of electric contacts 18L, 18R, 18E, 18D contacting resiliently with the ground 22 e.g. a wooden board, and being opened or closed through a conductive runway or path 21 set on the ground, the controlling mechanism being actuated in accordance with the opening or closing of the electric contacts. The driving mechanism may include a plurality of driving motors which independently drive their corresponding driving wheels. The controlling mechanism 9 may include means 25 for engaging a controlling motor M2 operated in response to the opening and closing of the contacts of the electrically-sensitive means and compulsorily prevents the revolution of at least one of the driving wheels, or circuits independently connected to the driving motors, the circuits being selectively and independently opened by the electrically-sensitive means, or a circuit connected to a reversible electric motor M2 which actuates a means or controlling plate 24 for selectively preventing the revolution of at least one of the driving wheels. The contact 18E connects with an electric source E2 of the driving motor M1 , the second contact 18D connects with the motor M1 and is optionally connected with 18E through the conductive runway 21 to operate the motor M1 by closing the circuit connecting the electric source E2 and the motor Ml and the pair of third contacts 18L, 18R optionally enable the reversible electric motor M2 to revolve in a regular or reverse direction by closing the circuit of the reversible motor M2. To operate, the vehicle is placed on the ground with the contacts 18D and 18E in contact with the conductive runway 21 and 18L and 18R in contact with the insulating ground or board. Circuit closure runs the motor Ml which propels the vehicle straight along the runway. At the bend 21b, the contact 18R comes into contact with the runway thus closing a circuit which runs the motor M2 in one direction thereby operating the controlling plate 24 which abuts on the rotary plate 8R, partially or wholly holding the wheel 1R and the vehicle turns right along the bent runway. Similarly at the bend 21c 18L comes in contact with the runway, the motor M2 runs in reverse direction and 8L and eventually 1L is held thus turning the vehicle left along the runway. At 21d, all the contacts are clear of the runway and the vehicle stops. A modification of the above is also described.

Filed: 1919-03-20
Abstract: 138,840. Anderson, W. P., Clarke, N. C., Whitelaw, J. F., and Read, R. H. March 20, 1919. Limbs, artificial.-In hands in which at least one pivoted finger and the thumb are adapted to be mechanically operated, one or more of the other fingers are coupled to the mechanically operated finger so as to open with it, but are independently spring-closed. The springs which close these fingers are so arranged as to tend to retain the fingers in one of two extreme positions on either side of a dead centre. Fig. 1 shows in plan section the fingers 2, 3, 7, 8 of which 2 and 3 are secured together so as to move together under the action of any suitable mechanism, e.g. that described in Specification 136,253. They are mounted on the spindle 1 which passes freely through the fingers 7 and 8. A pin 6 on the finger 3 works in a circular slot 5, Fig. 3, formed in the hub of the finger 7 in such a way that when it bears against the shoulder of the slot it clutches the finger 7 to the finger 3, and similarly a pin 9 clutches the finger 8 to the fingers 7. The slots in the fingers 7 and 8 allow them to be opened: independently of the finger 3 and springs 12, 13 tend, normally, to keep these fingers closed. They act on lugs 17 and thus tend to fix the fingers in one of the extreme positions shown in Fig. 2.

Abstract: 707,220. Fluid pressure brakes. THOMSON & TAYLOR (BROOKLANDS), Ltd., and WALKER, N. L. Nov. 23, 1950 [Nov. 23, 1949], No. 30042/49. Class 103(1) The brakes of a vehicle are adapted to be operated from either, or any. of two or more control points respectively governing independent sources of pressure fluid. In the arrangement shown in Fig. 1, the outputs from two master cylinders 2 and 5 act respectively upon coaxial pistons 7 and 10 in a transmitting unit 9, the end cylinder 6 of which acts as a pressurizing unit for the brakes connected thereto by pipe 3. Due to the difference in diameter of pistons 7 and 10, the effort from the master cylinder 5, which is shown as hand operated, is boosted up to a degree comparable with that exerted by the pedal operated master cylinder 2. In the arrangement shown in Fig. 2, the piston 20 of the transmitting unit, may be moved either by hydraulic pressure from a master cylinder connected by pipe 12 and passage 26 or by pneumatic pressure acting upon a servopiston 18. The pipe line 3 again leads to the brake cylinders and the line 22 to a hydraulic reservoir.

Title: Treatment of benzene hexachloride
IPC: C07C17/38
Filed: 1952-11-27
Abstract: Benzene hexachloride containing an enhanced concentration of the gamma isomer is obtained by extracting the mixed isomers at a temperature of 50 DEG  to 120 DEG  C., preferably 95 DEG  to 108 DEG C., with a solvent having two or more of the polar groups <FORM:0739167/IV (b)/1> , or with a solvent having a single polar group which associates to give a solvent which is equivalent to the polyfunctional solvents, and cooling the gamma enriched extract to a crystallizing temperature within the range - 15 DEG  to 90 DEG  C., more preferably between 20 DEG  and 80 DEG  C.  The crystallization is suitably carried out stepwise at a plurality of temperatures.  It is preferred to subject the mixture of isomers to a pre-extraction with a small amount of solvent at a low temperature to remove the delta isomer and other highly soluble constituents before carrying out the main extraction.  Specified solvents are ethylene glycol; diethylene glycol and its monomethyl, monoethyl and monobutyl ethers; b  : b -oxydipropionitrile; trimethylene glycol, propane 1 : 2 - diol; propane - 1 : 3 - diol; butane - 1 : 2 - diol; butane - 1 : 3 - diol; butane - 1 : 4 - diol; 1 : 2 : 3 : 4 - butane tetrol; diacetone alcohol; aldol; acetyl acetone; monoethanolamine; lactic acid and glycollic acid and as solvents which have a single polar group but which associate to give solvents which are equivalent to polyfunctional compounds formamide, dimethyl formamide and b  : b 1-dichloroethyl ether.  Examples are given illustrating the crystallization of benzene hexachloride from glycol, diethylene glycol, diethylene glycol monoethyl ether, b  : b 1-dichloroethylether, b  : b 1 oxydipropionitrile and formamide. Reference has been directed by the Comptroller to Specification 586,439.

IPC: B07C3/00
Filed: 1953-10-30
Abstract: 761,566. Sorting letters; endless-belt conveyers. STANDARD TELEPHONES & CABLES, Ltd. Oct. 30, 1953, No. 30096/53. Class 78 (1). [Also in Group XXXVIII] Timing equipment, particularly adapted for use in letter sorting systems, comprises a number of devices each of which includes a recording head 17 ... 20 and a reading head 21 ... 24 associated with a length of magnetic recording track 13 ... 16 formed on a rotatable brass drum 12A. When a letter 3 is carried by the conveyer 1 to a station 2, the operator thereat sets the switch 12 or presses a pushbutton, in accordance with the address to select the appropriate one of the tracks 13 ... 16, which causes the corresponding discharge device 8 ... 11 to be actuated when the letter has been carried to a position adjacent a pocket 4 ... 7, to transfer the letter to the pocket. Each pair of associated heads is so spaced that the time taken for a point on the associated track to cover the distance therebetween equals the time taken by a letter to travel from station 2 to a position opposite the appropriate pocket. If a letter is to be directed to the pocket 6, the switch 12 is set to the third working position and a potential is applied over the lead 25 to an operating circuit 26 associated with the head 19 of the appropriate track 15. When the letter reaches a predetermined position, a device 27, such as a cam actuated by the belt to close momentarily a pair of contacts, generates an electrical impulse which is applied over lead 28 to the operating circuits 29, 30, 26, 31 associated with the heads 17 ... 20, but only the circuit 26 delivers an output to cause the head 19 to record a " mark " on the track 15. When this " mark " reaches the head 23, it is amplified by an operating circuit 32 which causes the discharge device 10 to be actuated. As soon as the head 19 has recorded the "mark," the switch 12 is returned to its initial position by a potential applied over the lead 33.

Abstract: 1496233 Tangential jet false twisters HOLLANDSE SIGNAALAPPARATEN BV 21 July 1975 [21 Aug 1974] 30443/75 Headings DID, DIF and DIL A false twisting unit comprises a body 1 with a through cylindrical passage 2 which has tangential air ducts 4 from a cavity 3 fed by a channel 5, a further channel 6 also discharges into the passage 2 at or near the exit of tangential ducts 4. The further channel 6 is for the supply of liquid which can be an activating liquid for a potentially adhesive fibre component of a treated yarn. Such a yarn would be made cohesive by the false twist until activation of the adhesive took effect at which stage the yarn would be twistless. Alternatively, a non active bonding agent liquid can be supplied to be subsequently activated. The above liquids can be accompanied by a dye. A dye. can also be supplied to a twisted yarn which is untwisted by the false twisting action to aid penetration by the dye. In this latter case the roles of channels 5 and 6 are reversed, the false twisting occurring by tangential ducts 8 associated with channel 6. A further channel 9 supplies compressed air to induce a partial vacuum in passage 2. A movable member 12 controls the exit 11 from channel 9 which surrounds the passage exit.
