Title: Improvements in or relating to the spinning and winding of artificial filaments
IPC: B29C48/08
Filed: 1939-08-09
Abstract: 533,303. Artificial filaments &c. DU PONT DE NEMOURS & CO., E. I. Aug. 9, 1939, No. 23027. Convention date. Aug. 9, 1938. [Class 2 (ii)] Freshly formed artificial fibres, yarns, ribbons, and the like made from molten organic compositions are subjected to treatment with steam or other gas at elevated temperature and under conditions of high relative humidity between the point where they are extruded and the point where they are wound into package or other form. The treatment is carried out for a sufficient time to reduce or eliminate the tendency of the formed materials to undergo elongation upon subsequent exposure to the atmosphere. The treatment may be effected in apparatus comprising a steam treatment enclosure, a steam jacket, and means for passing steam through the jacket and for passing a small quantity of steam from the jacket to the enclosure. As shown in Fig. 1, a molten organic composition is extruded through spinneret 11 and the filaments 13 pass through the cooling tube 15. Cooling fluid passes through several conduits 19 and across the path of the filaments. It is removed from tube 15 through conduits 21. The filaments then pass through a steam treatment enclosure 23 supplied with steam from conduits 27. The filaments then pass in contact with a liquid-applying roller 35, around rolls 37, 39, and are then wound on bobbin 40. As shown in Fig. 2, the filaments pass through a tube 50 provided with sleeve 52 and steam jacket 54. Steam enters the jacket by pipe 56 and leaves by pipe 58. Some of the steam passes into the tube 50 through openings 59. The walls of tube 50 are maintained above the temperature of saturation of the steam to avoid condensation. The steam supplied to the jacket may be under superatmospheric pressure. For passing the filaments through the tube 50 when starting the treatment, fluid under pressure is supplied through tube 60. The filaments may be formed from synthetic linear polyamides, polyesters, polyethers, polyacetals, ethylene polymers, vinyl polymers, polystyrene, or polyacrylic acid derivatives. Plasticizers, dyes, pigments, delustrants, resins, and other substances may be incorporated in the filament-forming composition. Instead of steam there may be used moist air, e.g. air at 150F. or more and of relative humidity at least 90 per cent. In an example, polyhexamethylene adipamide is placed in a melting chamber and the molten material is pumped through a screen filter pack and then extruded to form filaments. These are passed through a cooling tube and solidified by directing air upon them. They are passed a short distance through the atmosphere and then through a steam treatment enclosure. They are stretched by drawing rolls and wound under tension. The Specification as open to inspection under Sect. 91 comprises also the treatment of cellulose derivative products obtained by melt-spinning. This subject-matter does not appear in the Specification as accepted.

Title: Improved printing method and system
IPC: B41J7/68
Filed: 1956-07-26
Abstract: 818,883. Electronic counting apparatus. HEWLETT-PACKARD CO. July 26, 1956 [Aug. 12, 1955], No. 23196/56. Class 106 (1). [Also in Group XVI] A printing machine of the kind selectively operated by information in the form of source potentials each corresponding to a character to be printed, comprises a number of type carriers, e.g. wheels 46 or linear members, means whereby reference potentials, corresponding to the type characters are formed, and means whereby the characters are successively brought into printing position so that when the reference potential is coincident with the source potential, printing is effected. The printing wheels 46 incorporate contact brushes 57, Fig. 6, which wipe over a series of contacts on an adjacent commutator plate 56. Also incorporated is a friction clutch comprising a friction washer 54 and a drive member 52 keyed to a shaft 42 driven by a shaft 36 and gearing 41, 39, Fig. 1, so that the type wheels may make two revolutions to each revolution of a shaft 13. This shaft is driven from a drive 12-18 through a clutch 21-23 controlled by an electromagnet 33 that normally holds the clutch in its disengaged position. The clutch is engaged when an electronic counter or other apparatus employing an electronic fast gate, sends its gate pulse to the electromagnet 33 to release it, whereupon a spring 31 and lever 26 operate the clutch to start a printing cycle. The counter C, Fig. 13, may be a decade counter and consists of four flip-flop or bi-stable multivibrator circuits (Fig. 9, not shown) connected in cascade. Alternatively a decimal counting system may be used comprising four flip-flops in cascade and counter feedback circuits. These are arranged so they produce the same effect as six additional input pulses, thus the four flip-flops in cascade will go through a complete cycle of operation in ten input pulses. These counters provide a set of potentials which are proportional to the count or character to be printed and are supplied to coincidence means 181-184. The reference potentials representing a second set of voltages are generated by a potential divider tapped by the brush and commutator mechanism 56-57 and correspond to the particular character which is in the print position for each of the type carriers. These reference potentials are also supplied to the coincidence means over lines 197-200 and when coincidence is registered between these and the source potentials an electromagnet type carrier lock 74 is released and a detent 71 positions the type carrier in selected position. The next revolution of the shaft 36 effects printing by means of the cam 76 engaging the printing bar 77. Specification 818,884, [Group XVI], is referred to.

Title: Improvements in respirator machines
Inventor: BLEASE JOHN HENRY
IPC: A61M16/00
Filed: 1960-07-04
Abstract: 879,017. Respiratory appliances. BLEASE ANAESTHETIC EQUIPMENT Ltd. July 4, 1960, No. 23321/60. Class 81 (2). A respiration machine comprises a main chamber 2 separated from an auxiliary chamber 4 by a diaphragm 6. The auxiliary chamber is vented to atmosphere through a one-way valve 24 and the main chamber is provided with an inlet port 12 and an outlet port 14 which are opened automatically by valve members 34, 36 respectively by movement of the diaphragm between its two extreme positions. The main chamber is also connected to the patient through one way inhalation and exhalation valves 16, 18 respectively. Movement of the valves by the diaphragm is effected by a rod 28 carrying a blade spring 30 which, when stressed, tends to turn a pivoted disc 32 to which the valves are connected, but which it cannot move until the diaphragm reaches the limit of its movement, where an abutment on the rod 28 releases a detent arrangement 26. Air is admitted through a biased bellows 40, which maintains a relatively constant pressure, to the inlet valve 12 and so raises the pressure in the main chamber 2, whereby air passes to the patient through valve 16. The diaphragm 6 is moved outwards by the increasing pressure until it closes the inlet valve and opens the exhaust valve. However, the diaphragm cannot commence to return until the pressure in bellows 40 has risen to a value which actuates a diaphragm 50 to open a valve 54. This connects the auxiliary chamber 4 to atmosphere, allowing air to enter, so that the diaphragm can return under the influence of a bias spring 8. During this period the patient exhales through valve 18 and, if desired, exhalation can be assisted by an extractor jet 60. A pressure gauge 20 and flowmeter 22 may be connected in the respiratory circuit to check the flow to the patient.

S., 19, Grange Close, Hayes, Middlesex. Aug. 19, 1932, No. 23340. [Class 40 (ii).] Relates to devices in gramophones, particularly of the magazine type, for preventing slipping of the records on the turntable. According to the invention, the machine is provided with a slotted or recessed spindle adapted to enter the central hole of a record, a member being movable within the slot or recess in such a manner as to be capable of being withdrawn into the spindle to allow a record to pass over it, or to be projected outwardly into firm engagement with the edge of the hole. The invention is shown applied to a magazine gramophone having record-feeding mechanism of the kind described in Specification 359,106. A spindle 22 which guides the records on to and centres them upon the turntable 2 forms an extension of the turntable spindle 1. A lever 44 is pivoted in a slot 43 in the spindle 22, the lower end of which engages in a socket in the end of the spindle 1. In the spindle 22 is a spring 85 which tends to force the upper end of the lever 44 outwardly, Fig. 4. When a record is to be allowed to fall from supports 10, 8 down the rod 22, the upper end of the lever 44 is withdrawn into the slot in the rod 22, and when the record has reached the turntable, the lever is allowed to move, under the action of the spring 85, into firm engagement with the edge of the hole in the record. These movements of the lever 44 are controlled by members 46, 51 reciprocated by a cam in timed relationship with the movements of sliding plates 14, 19 which operate the record-releasing devices in the manner described in the said prior Specification ; the members 46, 51 co-operate with a pair of interconnected levers 32, 33 and a third lever 29 engaging through a slot in the spindle 1 with the lower end of the lever 44. Fig. 7 shows a modification in which the record-retaining lever 44 is operated by a tiltable plate 57, adapted to be rocked in slots 58, 59 in the turntable boss 55 by cam-controlled means. A further modification is described (Figs. 9-12, not shown) in which the record-retaining lever is actuated by a slidable plate, controlled by an eccentric on the turntable boss.
