Title: Method and/or means for producing associated products in printing machines
IPC: B41F13/68
Filed: 1938-05-19
Abstract: 514,966. Automatic electric control systems, HOE & CO., Ltd., R. (Hoe & Co., Inc., R.). May 19, 1938, No. 14984. [Class 38 (iv)] [Also in Group XVI] The association of a preprinted and a freshly printed web travelling at similar speeds is effected by registering the webs at a point adjacent the point of association and immediately severing the registered sheets and forwarding them into association with the freshly printed web. The preprinted web 26 is fed by a roller 31 co-operating with rollers 32, 33 to cutting-cylinders 102, 103, and sheets cut therefrom are forwarded by rollers 106, 107 co as to be associated with the webs 11 ... 14 prior to the webs passing over the folding former 24. The roller 31 is driven from the printing-machine through a differential gearing, the casing of which is rotated in either direction to correct the register of the web 26. For controlling the rotation of the casing, marks printed upon the web end separated by a distance equal to the' printing-cylinder circumference are adapted to affect a photoelectric cell. A cam 35 driven from the printing-machine is adapted to close a switch 34 once for each revolution of the printing-machine. When the cell 28 is affected by the mark it causes energization of a solenoid 42 which actuates a switch 64 causing an electric motor 61 to drive the casing in one direction. At the same time a switch 44 in the circuit of the switch 34 is opened. On the other hand the closing of the switch 34 causes energization of a solenoid 49 which actuates a switch 65 causing the motor 61 to rotate in the opposite direction and at the same time opening a switch 52 in the circuit of the cell 28. If the cell 28 and the switch 34 are affected simultaneously, i.e., when the web 26 is in correct register, closing of the switches 64, 65 cannot take place. In a modification, the casing is rotated by a pawl actuated by one or other of two solenoids, one of which is energized when the solenoid 42 is energized and the other of which is energized when the solenoid 49 is energized. In order to ensure stripping of the sheets from the cutting-cylinders, two pairs of cutting-cylinders may be employed. The first pair 116, 117 form partial cuts in alignment with guide bars 111 engaging grooves in and adapted to strip the sheets from a second pair of cutting-cylinders which complete the severance of the sheets.

Filed: 1966-04-05
Abstract: 1,095,106. Thermoelectric devices. LEEDS & NORTHRUP CO. April 5, 1966 [April 6, 1965], No. 15093/66. Heading H1K. An expendable immersion thermocouple assembly, for measuring the temperature of molten metal, is provided with thermallyinsulated lead wires packed adjacent to the assembly so that the wires may be extended in use. The assembly may be dropped into a " basic oxygen " furnace, or may form part of a telescopic lance which is extended before insertion into an " open hearth " furnace. As shown, Fig. 1, the thermocouple wires 11, 12 are mounted in refractory cement 15 and are protected by a refractory tube 14 and a fusible cover 17. The arrangement is mounted in the end of a cardboard tube 18 which is provided with a steel or cast iron weight 28. The thermocouple wires are connected to lead wires 23, 24 which are protected by a thermallyinsulating cover to form a cable 25 which extends through tube 18, to the end of which it is fixed by staples 27. The remainder of the cable is wound round the tube 18, and the ends 23a, 24a of the leads are connected to measuring apparatus. When the assembly is dropped into the furnace, the cable 25 unwinds and provides a spring effect which reduces the impact when the assembly hits the surface of the molten iron. The thermocouple wires are of platinum plus 6% rhodium and platinum plus 30% rhodium and both lead wires are of copper. A known type of temperature recorder for use with platinum/platinum plus 10% rhodium thermocouples may be used by incorporating a compensating circuit, Fig. 2 (not shown). In a modification, Fig. 3 (not shown), the cable is packed inside the cardboard tube (18A) which fits inside a fixed tube (55) from which it may be projected by means of a spring (58) or an explosive. The head of the assembly is provided with a ceramic rod (68) to prevent the thermocouple coming in contact with the bottom of the furnace. The assembly may also be projected by packing the tube with a propellant so that the device forms a rocket. In a second modification, Figs. 4 and 5 (not shown), the thermoelectric assembly is mounted directly in the weight (72) and the cable is coiled and supported by paper strips (18B) or is wound round a cardboard tube which is not projected into the furnace. An extending lance, Figs. 6 to 9 (not shown), comprises a cardboard tube (18C) lying in a pipe (86) and having the thermocouple assembly mounted at one end. The cable (25C) is folded inside the tube (18C) and is terminated by a connector (81) cemented to the end of the cardboard tube (18C) and engaging a connector (85) provided on the end of the pipe (86). The pipe (86) is provided with a slot through which a pointed projection of a handle (92) may be forced into the cardboard tube (18C) so that the tube can be mechanically separated from its connector (81) and moved down the pipe, thus doubling the length of the lance.

Title: Improvements in the manufacture of cellulose derivatives
IPC: C08B3/00
Filed: 1933-05-26
Abstract: Cellulosic material is subjected to treatment with a medium comprising an organic acid and sulphuric or phosphoric acid and free from organic anhydride.  The mineral acid is partially or completely neutralized and the cellulosic material is then converted into the required cellulose ester in the presence of sulphuric or phosphoric acid as catalyst.  The process may be used for producing cellulose acetate, formate, propionate, butyrate, laurate, benzoate, acetatepropionate, nitroacetate, or other ester or mixed ester.  The products may be used for the manufacture of artificial threads, foils, lacquers, and plastics. The cellulosic material may be cotton linters, or wood pulp from which lignin, pentosan resin and similar constituents have been removed.  The organic acid of the pretreatment may be formic or acetic acid.  Acetic anhydride may be employed to remove the water content of the acetic acid.  The proportion of mineral acid is preferably small compared with that used in the subsequent esterification.  The pretreatment may be carried out in the cold or with heating.  Ammonia, an alkylamine, or other organic base may be vaporized through or otherwise incorporated with the cellulosic material to neutralize the mineral acid, or the salt of a weak acid such as sodium acetate, carbonate, or bicarbonate may be used for the same purpose.  The substance used for neutralizing the mineral acid may be contained in the acetic acid or other medium serving as solvent or diluent in the acetylation or other esterification.  The esterification may be carried out so that the cellulose ester is obtained in solution or in suspension.  In an example, cotton linters are sprayed with a mixture of glacial acetic acid and sulphuric acid.  After standing for several hours the cotton linters are placed in an acetylator containing glacial acetic acid and sufficient sodium acetate to neutralize 80--90 per cent of the sulphuric acid.  Acetic anhydride and sulphuric acid are added and acetylation is carried out.  The primary cellulose esters obtained may be used as such or first submitted to a ripening process. Specifications 20977/11, 20852/12, 207,562, 249,173, [all in Class 2 (ii)], and 407,018 are referred to.  The Provisional Specification refers also to the use of other mineral acids such as hydrochloric, and perchloric acid in the pretreatment of cellulosic material.

Abstract: 710,951. Clocks and watches. HERCHENHAN, H. June 27, 1951 [June 27. 1950], No. 15267/51. Class 139 In an escapement for time-pieces there is, between the balance wheel and the escape wheel, a multi-armed lever controlled by a compensation spring, the arrangement being such that the said lever, when freed, imparts an impulse to the balance as the balance swings in one direction, then frees the escape wheel from a spring detent to allow it to turn one tooth to re-set the said lever and restress the compensation spring, this lever then being locked by a detent, which is released by a discharge finger on the balance wheel in the succeeding swing of the balance in the same direction. As the balance 1 swings clockwise the pin 3 meets a spring 20 and so moves a detent 18 carried by spring 19 to free a pivoted multi-armed lever 5, 8, 9, 10 to the action of a spiral spring 7. The lever 5, 8, 9, 10 swings anticlockwise and its arm 9 meets. the impulse pin 2 to impart an impulse tothe balance. The edge 14 of the semicircular counter weight 5 of the lever then moves a detent 16 carried by a spring 17 away from the external teeth 130, 131...., of the escape wheel 11 which is thereby freed to rotate clockwise. The escape wheel 11 also has internal teeth 120, 121, 122 ..... which successively co-operate with a pallet pin 15 carried by the part. 5 of the lever to reset the lever to the position in which it is locked by the detent 18 engaging the end of its arm 10 and in which the spring 7 is stressed. An impulse of constant strength is therefore imparted. to the balance every time it swings. clockwise.

Abstract: 1,104,853. Automatic control. LICENTIA PATENT VERWALTUNGS G. m. b. H. April 12, 1965, No. 15495/65. Heading G3R. In a manual/automatic control system apparatus is provided to render the changeover from manual to automatic control relatively smooth to avoid shock to the system. When switches 11, 14 are in positions opposite to that shown, an electrical signal X w  dependent on deviation of the value of a variable is applied through an amplifier 1 to produce an output at Y which is utilized to correct the deviation. Feedback through an element 2 introduces an integral component of control. Introduction of a differential component of control is also referred to. As shown, however, the variable is being controlled manually by a controller 8 and the deviation signal X W  is applied through a polarity reverser to the input of amplifier 1. The output of the amplifier is maintained equal to the value it would have during automatic control by feeding back through an element 3 the difference between the manual control signal and the output of amplifier 1. Then, if the system is switched to automatic control, the elimination of this feedback by switch 11 causes the amplifier output to rise to equal the manual control signal so that shock is prevented. The system thereafter adjusts itself to correct the variable. The gain of feedback element 3 is adjusted to equal the reciprocal of the gain of the automatic controller and, if the latter is adjustable, the gain of element 3 is adjusted simultaneously.

Abstract: 826,431. Reciprocating pumps. JAMES, E. P. May 8, 1958 [May, 16 1957], No. 15517/57. Class 102(1). [Also in Group XXIX] A bilge pump comprises a casing 10 provided with an inlet port 18 and outlet ports 17 and a spring loaded piston 14 having its stem 13 projecting through the casing, an attachment aperture 16 being formed in a yoke 15 which is screwed onto the end of the stem 13 and a shackle 21 being pivotally secured to a plate 20 which is fixed to the other end of the casing 10, the attachment means 16, 21 enabling the pump to be mounted in parallel with a portion of the anchor line 39 of a craft 40. A piece 19 is attached to the inlet 18. When this pipe is placed in a liquid and the piston 14 reciprocated, liquid will be drawn into the casing 10 through a valve 22 on the first stroke, will then pass through a valve in the piston 14 on the second stroke and on the third stroke a further quantity of liquid will be drawn into the casing whilst the original quantity of liquid is expelled through the ports 17. A tension spring 34 surrounds the casing 10, one end being fixed to the casing and the other end formed into a hook 35 engaged in the yoke 15. A second spring 38 is a compression spring which is mounted in the casing 10 and only becomes effective when the piston has exceeded a predetermined length of stroke. As shown in Fig. 2, the pump is secured in the anchor line 39 of a boat 40 so that movement of the boat will cause operation of the piston 14. The pump is so connected in the anchor line 39 that a loop 41 is provided so that in the event of a mechanical breakage of a part of the pump the boat will still be secured to its anchor. Under normal conditions movement of the boat will merely expand the spring 34 which will provide sufficient movement for pumping small quantities of water from the bilges. In rough weather the spring 38 will be compressed and give a more rapid stroke to the pump.
