Title: An apparatus for feeding tapered containers singly from a stack
IPC: B65G59/10
Filed: 1961-06-16
Abstract: 953,231. Feeding cartons. JAGENBERG-WERKE A.G. June 16, 1961 [June 18, 1960], No. 21822/61. Heading B8S. A paper carton is withdrawn from a stack of cartons in magazine 2 by gripper 4, and is then reversed by rotating arm 5 so that it is ready to receive liquid from filling nozzle 14 and be discharged by endless belt 13. The upward movement of gripper 4 operates the intermittent rotation of arm 5. Thus, gripper 4 moves upwards towards magazine 2 and as it does so a ratchet carried thereby operates a gear-wheel to cause rotation of arm 5 through 180 degrees. This inverts the previous carton. Then the gripper 4 grips the lowermost carton of magazine 2 and withdraws it downwards, till the carton rests on fixed support 9 and is gripped by arm 5, the downward movement of the rack causing the free wheeling of the gear-wheel without causing rotation of arm 5. When gripper 4 next advances upwards its rack causes rotation of arm 5 clockwise to deposit the carton into a holder 12 pivoted at 20. The carton rests on door 10 which is pivoted at 19 to yield to permit the rotation of arm 5. Holder 12 transports the carton by a pivoting and reciprocating movement on to belt 13 and after being filled by nozzle 14 it is discharged by the belt.

Title: Improvements relating to motor speed control systems
Inventor: SHAW NORMAN HARRY
IPC: H02P25/28
Filed: 1959-06-25
Abstract: 950,724. Control of A.C. motors. ENGLISH ELECTRIC CO. Ltd. June 22, 1960 [June 25, 1959], No. 21828/59. Heading H2J. [Also in Division G3] To control the speed of a three-phase squirrelcage induction motor I.M., e.g. for a knitting machine, a saturable reactor SR is included in the supply circuit and the motor has a braking winding BW; the D.C. control winding of the reactor is energized by a control circuit in which the output of a tacho-generator TG is compared with a reference voltage to maintain the speed constant, but if it becomes too high (e.g. if the reference voltage is reduced), the brake winding is energized with D.C. instead of the control winding. The reference voltage is derived from either of potentiometers P1 or P2 and both may be preset so that a finite change of speed is obtained by operating a switch SW. This voltage is compared with that of TG at R1 and the difference applied to the base of a transistor TR1 whence, after further amplification in transistors TR2 and TR4, it energizes the control winding of the saturable reactor. The brake winding is energized by transistors TR3, TR5, TR6, the first of which is biased by potentiometer P4 so that there is no output until the voltage of TG exceeds that of the reference by a predetermined amount, when the error signal, via TR1, causes these transistors to conduct, at the same time blocking TR4 and so de-energizing the control winding of SR. The control winding is shunted by a rectifier HR and resistor R5 to absorb self induced voltages, the braking winding BW is two-pole while the main winding is four-pole to reduce A.C. pickup in BW, and the zero speed position of potentiometers P1, P2 is adjusted by a further one, P3. It is stated that the amplifiers may alternatively be valve or magnetic amplifiers.

Title: Improvements in or relating to circuits for television receivers and the like
Inventor: MARSHALL CHARLES ACTON
IPC: H04N5/60
Filed: 1954-07-27
Abstract: 772,620. Television. MULLARD RADIO VALVE CO., Ltd. July 27,1954, No. 21913/54. Drawings to Specification. Class 40 (3). [Also in Group XL (c)] Interference caused by accompanying amplitude-modulated sound signals in the picture reproduced by a television receiver is reduced by including a filter which suppresses signals having a frequency corresponding to the difference between the sound and vision carriers in the circuit between the vision detector and the picture reproducing tube. This arrangement, whilst giving sufficient sound rejection in the reproduced picture, allows some sound interference to remain on the synchronizing signals and this effect is reduced either by " flywheel " techniques or by causing cancellation of the interference by combining signals derived from the sound channel in suitable amplitude and phase with the composite vision signals prior to separation of the synchronizing signals.

Abstract: 1,186,412. Pipe joints; screw-threads. VETCO OFFSHORE INDUSTRIES Inc. 12 May, 1967 [25 July, 1966], No. 22053/67. Headings F2G and F2Q. In a tool joint for connecting pipe sections together a box member 11 has an internal, tapered thread 14 of generally trapezoidal form and a pin member 10 has an external thread 15 companion to the thread 14, the member 10 having a drive shoulder 17 which engages the outer end 16 of the member 11 when the members are fully coupled together. The threads 14, 15 have respectively drive faces 19, 40 normal to the axes of the members 11, 10, back faces 20, 41 inclined to the drive faces, and flat crests 21, 42, substantially parallel to the axes of the members; when the members are fully engaged, the drive faces engage each other and the back faces are free from contact with each other and the crests of the thread of the pin and box members have clearance with the roots of the thread of the box and pin members respectively, whereby longitudinally directed forces acting on the joint impose no hoop stress on the joint. As shown, the roots of the threads are curved, as are also the corners between the drive faces and crests and the latter and inclined back faces. The particular shape of the thread facilitates stabbing of the pin into the box despite any misalignment between those members and screwing together of the members may be accomplished by the use of air hammers connected to or brought to bear against lugs secured to the pin members. When driving a string of pipe into the sea bed the uppermost pipe section has threadedly attached thereto a drive head for engagement by a pile driver head, Figs. 1 and 2 (not shown).

Title: Improvements in or relating to the colouration of textile and other materials
IPC: D06P1/645
Filed: 1936-08-13
Abstract: Vat dyes, dyeing with; cellulose esters or ethers, dyeing; printing.--Textile materials, films or foils made of or containing cellulose esters or ethers are coloured by applying thereto a leuco compound of a vat dyestuff in a liquid medium of which the major proportion is organic liquid and which contains an organic base and a neutral organic liquid and thereafter oxidizing the leuco compound to the vat dye-stuff on the materials.  Specified neutral organic liquids are petrol, benzene, toluene, xylene, carbon tetrachloride, perchlorethylene, di- and tri-chlorethylenes, methyl, ethyl, propyl, isopropyl and butyl alcohols, acetone and ethyl, propyl and isopropyl acetates.  Such liquid or the major part thereof is advantageously a swelling agent for the material treated.  Specified organic bases are butylamine, amylamine, cyclohexylamine, N-dimethylcyclohexylamine, mono-, di- and tri-benzylamines, dimethylbenzylamine, p dimethylaniline, trimethylbenzylammonium hydroxide, pyridine, alkylpyridines, quinoline and piperidine.  For preparing the dye liquor, the vat dye may be reduced in the presence of the organic base, specified reducing agents being zinc formaldehydesulphoxylate, zinc (preferably with the addition of a little copper or copper salt) and sulphuretted hydrogen. Alternatively, the free leuco compound of the vat dye, precipitated by acidifying an alkaline vat, may be dried and mixed with the organic base, before or after the addition of a neutral organic liquid, and such drying may be effected by boiling with an organic liquid forming with water an azeotropic mixture of minimum boiling point, advantageously a liquid, e.g. benzene, which is a suitable constituent of the dye liquor.  The materials may be immersed in or passed through the dye liquor or the latter may be applied by printing or by padding as described in Specifications 469,908, 470,333; and 470,334, [Group XIII], or circulated through the materials in package form.  In examples: (1) cellulose acetate yarn is dyed blue by immersing it for 1 hour in a solution at 80 DEG C. made by dissolving Ciba blue 2B in pyridine and adding zinc form-aldehydesulphoxylate and petrol, and, thereafter, washing with cold petrol and drying and, if desired, treating with a dilute soap solution containing hydrogen peroxide; (2) cellulose acetate artificial silk is similarly dyed pink with Ciba red G; (3) cellulose acetate fabric is printed with a preparation obtained by dissolving Ciba blue 2B in pyridine, adding zinc formaldehydesulphoxylate, isopropyl alcohol, gum arabic and water and the printed fabric is steamed for 20 minutes, treated with a dilute soap solution containing hydrogen peroxide and dried.  Specifications 448,816, 448,817, and 448,917 also are referred to.  The Provisional Specification includes also the application of the process to other fibres, e.g. silk and wool.
