Title: A method and means in looms for holding the weft end of a bobbin to be introduced into the shuttle
IPC: D03D45/50
Filed: 1956-11-30
Abstract: 800,840. Automatic bobbin-changing looms. RYDBOHOLMS AKTIEBOLAG. Nov. 30, 1956 [May 28, 1956], No. 36662/56. Class 142(2) To secure the weft end of a bobbin 44 during the first pick or picks, a sleeve 43 is advanced axially over the bobbin in the transfer position and withdrawn again, air being blown out of obliquely directed nozzles 53 to whirl up the weft end and suction being applied at an annular slot 48 to suck the end in to an annular channel 47, in which position it is then clamped by a plug 54. The sleeve is advanced and withdrawn by a double acting cylinder 36, to the appropriate end of which compressed air is supplied through conduits 59, 62. The supply of compressed air to the nozzles 53 is controlled by a valve 51 on the sleeve, operated by coacting member 60 and relatively stationary cam member 61. Suction is applied to the slot 48, through a conduit 45, 46, as the sleeve reaches its extreme position of advance. The plug 54 is normally situated in that end of the sleeve remote from the bobbin, but after being carried forward for a while, is left behind (the sleeve continuing to advance) as an abutment 58 on its supporting slide 56 meets a member 57, and later re-enters the sleeve as the latter withdraws from the bobbin. The sleeve tapers from both ends to a restricted throat of diameter only slightly greater than that of the wound bobbin and in which the suction slot 48 is situated; and the plug 54 is tapered to mate with its end of the sleeve. That bobbin which is in the transfer position is held there in a carriage 15 until, under the influence of a weft feeler, a latch 29 is swung into the path of a bunter 30 on the slay and a bell-crank 27 is swung clockwise to force into the shuttle the new bobbin, which simultaneously ejects the spent bobbin. The carriage is now reciprocated by a double-acting compressed air cylinder 18 and, as it approaches a position under a magazine outlet 14, a projection which it carries swings a bell-crank 21 counterclockwise so that a hammer 24 knocks the lowermost waiting bobbin into the carriage

Patent GB-1074388-A (GB)
Title: A web marking device for paper web winding apparatus
IPC: B41F17/00
Filed: 1964-09-08
Abstract: 1,074,388. Feeding webs; ruling devices. B. KIRSCH. Sept. 8, 1964, No. 36812/64. Addition to 975,572. Headings B6B and B6P. In the web winding apparatus of Specification 975,572, predetermined lengths of web are wound, and are provided near the end of each web with an end marking which indicates to the user in good time that the web-roll will shortly be exhausted when being used in a machine such as a graphic recorder. The present invention relates to a marking device capable of being used in combination with the web winding apparatus of Specifiction 975,572. The device includes two parallel guide rods 1 and 2, Fig. 1, connected together by means of cross-pieces 3 and 4. Cross-piece 4 is mounted to the housing 5 of the web winding apparatus, the table 22 and guide roller 24 forming part thereof, the mounting being such as to allow the cross-piece 4 to pivot so that the guide rods are elevated from the table 22 under the action of an electromagnet 6. The web of paper 23 passes over the table 22 and roller 24 and beneath the marking device. A triangular carriage 7 for the marking element such as a pencil, has three rollers 9, 10 and 11 at the apexes, Fig. 3, which rollers engage the parallel rods 1 and 2. Attached to the carriage is a holder 12 and a ring 13 through which the pencil may be passed and locked in position. Located beneath the carriage is a peg (14, Fig. 4), which has a recess (15) for the locating wheel (16) carried on a pin (17). The peg (14) and therefore the wheel (16), is adjustable obliquely with respect to the carriage or direction of movement of the web, with the aid of an adjusting screw (18). When the marking device is tilted downwards against the web 23, with carriage 7 in the position shown in Fig. 1, the web is nipped between the guide roller 24 and the wheel (16), thereby driving the wheel. Due to its oblique positioning, the wheel (16) drives the carriage 7 along the guide rods 1 and 2, and a line is drawn obliquely across the web with the pencil. When the carriage reaches the stop 20, a switch is actuated to operate the electromagnet 6 which tilts the rods upwards. The carriage then moves back along the guide rods under its own weight as far as the second stop, where it is again in position ready for use. As an alternative arrangement, the guide rods 1 and 2 are supported in a yoke which is supported in balance fashion from a central point, Fig. 5 (not shown). With one end of the yoke fixed and the central point raised by an arm with an electromagnet, the guide rods are tilted in a similar manner as above. The marking pencil need not be attached to the carriage but may be adjustably attached to one of the guide rods so that as the carriage moves along the guide rails, a pencil line is drawn on the web parallel to the direction of movement of the web.

Abstract: 1484637 Treatment chambers PIELKENROOD-VINITEX BV 22 Aug 1974 [25 Sept 1973] 36857/74 Heading A5R [Also in Division F4]  A device for maintaining a dust and germ free zone over an operating table 11 comprises a cabinet 1 as described in Specification 1393394, having a vertical air exit surface and housing blowers and filters, and a U-tube 20, 21 for suspension along both sides and the free end of the table 11, the tube being apertured to deliver germ-free air transversely and downwardly and being connected by T- joints 30 to an air supply duct 31 supplied with air by a filter and blower unit 36, 37, the T-joints being rotatable about the axis of the duct 31 to permit pivoting of the U-tube from a horizontal position to a vertical position. The T-joints 30 may form a single unit slidably mounted on tube portions to define the duct 31, whereby the U-tube 20, 21 may be moved transversely relatively to the table 11. Alternatively, the T-joints 30 are separate and are slidably mounted on tube portions 31' and the bight portion of the U-tube includes a telescopic portion 32 to permit adaptation of the U-tube to tables 11 of different widths. The arms of the U-tube may be telescopically formed. U-tubes 33 pivotally connected to duct 31 and a further parallel supply duct 34 allow the U-tube to be raised or lowered 'with parallel motion. Curtains 15 on guides which are hingedly mounted on each side of the cabinet 1 may be swung to positions closing the front of a space in which the U- tube can be positioned vertically. Disinfectant sprayed into the space is collected in a trough 28 and passes to a filter 42. The blower 36 draws air from a chamber 38 having an air inlet controlled by a slide 40 and an inlet 41 from the filter 42, whereby with the slide 40 closed, air flows from blower 36 through the raised U-tube, the trough 28 and chamber 38 in a substantially closed circuit. Alternatively, filters 37, 42 communicate with blower 36 via separate valve controlled ducts so that filter 37 may be excluded from the circuit. The cabinet 1 is mounted for horizontal and vertical displacement on a support structure having wheels and vertical hydraulic jacks.

Title: Checking an automatic testing system
IPC: G06F11/267
Filed: 1968-08-02
Abstract: 1,210,289. Programmed control of testing. RCA CORP. Aug.2, 1968 [Aug. 22, 1967], No. 36941/68. Heading G3N. [Also in Division G1] An automatic testing system comprises a simulator of an article to be tested and circuits for applying a special programme of stimuli to the simulator, representing the stimuli that the testing system generates during testing an article, to which the simulator responds by producing outputs representative of acceptable and non-acceptable articles. On a test conveyer system, as disclosed in Specification 1, 206, 357, there are placed a number of kinescope simulators which, when connected to the conveyer controller, call up a simulator programme for checking the operation of relays in a test station. It is stated that the detection of a system fault calls up a diagnostic sub-routine, or, when the fault requires a detailed analysis, the conveyer is stopped and the computer performs an off-line diagnosis; the result of either diagnosis being printed out. The simulator comprises a group of relays and resistors located in a kinescope-shaped metal casing having pins corresponding to the pins terminating the neck of a kinescope and an anode terminal corresponding to that of a kinescope. The casing has a card attached to it which, when read by the card reader, indicates to the digital computer that a simulator is present. The computer then selects from its memory a special test programme of instructions. As shown, the terminals F-G2R correspond to the terminals present on a colour kinescope. A resistor R1 simulates the filament and is supplied through a bridge rectifier 15, a block 17 simulates high voltage arcs by the sequencing of relays by a block 19 and a lamp 21 simulates emission of light from certain of the kinescope electrodes. The resistors R10, R2, R8, R13 are employed to simulate resistances between the filament, cathode and grids. The energization of a relay K9 causes closure of a contact RK9 in the block 19 and the application of direct current to relays K18, K16. Relay K18 is activated first and then is deactivated as relay K16 is activated at time intervals determined by condensers C2, C7 and resistors R15, 20. Contacts RK18a, RK18b, open and close respectively causing condenser C13 to discharge through a transformer 73 to simulate an arc at anode 77. Further arc simulations are effected by the sequential operation of relays K12, K15, K17, K19. Inter-grid leakages are simulated by the passage of current through resistors R4, R7, R12 by the selective actuation of relays K1 - K9.
