Title: Improvements in or relating to means or apparatus for heating cordite discs or other materials
IPC: C06B21/00
Filed: 1926-08-25
Abstract: 280,653. Barker, J. H. Aug. 25, 1926. Heating systems.-Cordite discs 28 are moved intermittently through a chamber or oven 10 on a heated bed 4, Figs. 3 and 5, by means of pushers 25 loosely mounted on transverse bars 19 carried by trucks provided with a reciprocating. movement. The hollow bed 4, which is adapted to be heated by steam, hot water, or oil, has a top plate 27 and is mounted upon girders 3 carried bv pillars. Above the bed is a hood 9 composed of iron plates forming an oven 10 divided into a number of compartments by partitions 14. The trucks, each of which consists of a pair of angle-irons 17, Figs. 12 and 13, braced together by metal strips 18 and transverse rods or tubes 19, are adapted to reciprocate on rollers 20 mounted on angle-irons 16 fixed to the partitions 14, and side rollers 22 are provided to, centralize the trucks. If desired, the angle-irons 16 may be dispensed with and the truck frames may slide on rollers mounted directly on the partitions 14. The pushers 25, loosely mounted on the rods 19, are in the form of pawls, a pair of which is adapted to engage the periphery of each disc 28. Three longitudinal rows of cordite discs are provided in each compartment of the oven, and these rows are spaced apart by means of members 26 fixed on the bed-plate 27. The angle-irons 17 are extended as at 17<(x)>, Fig. 5, and are pivotally connected to hell-crank levers 29. 37, the arms 37 of which are weighted. Motion is imparted to the trucks by means of cams 40 engaging the arms 29 of the bell-crank levers, and the cams are so arranged that whilst certain of the trucks move outwards, others move inwards. The cams are mounted on a shaft 41, Fig. 3, to which rotary motion is imparted by an electric motor through worm gear 44, 46, or from a driven pulley 50 through spur gear 51, 52, 53 and worm gear 44, 46. Other reciprocating means may, however, be provided. At the delivery end of the machine the bed-plate 27, which projects beyond the hood 9, is provided with holes 59 in order that the discs 28 may be caused to drop vertically through the holes on to a delivery band 36 in a trough 8, Fig. 3. A guide is provided above the upper surface of the travelling band 36 for deflecting the discs on to a table. The endless band 36 passes over pulleys 62 - - 65, Figs. 3 and 9. The pulley 62 is mounted in a sliding member adjusted by a screw, and the pulley 65, Fig. 9, is carried in bearings 71 formed in a pair of plates 72 sliding in grooves and connected by a transverse rod 73, from which a weight 77 is suspended. The pushers 25 may consist of two vertical sides hav. ing a skeleton or solid transverse bottom in which is an opening, and one end of each vertical side may be inclined and be shaped like a pawl with a pair of hooks. Each of the compartments of the oven is provided with a cover 11, Fig. 5, and a flue 12, and at the junction of the hood 9 and the flue 12 a perforated paper disc 15 may be arranged. Specification 275,743 is referred to.

Title: Web winding process and apparatus
IPC: B65H23/195
Filed: 1966-05-11
Abstract: 1,097,162. Controlling clutches. E. I. DU PONT DE NEMOURS & CO. May 11, 1966 [May 12, 1965], No. 20945/66. Heading F2L. [Also in Division G1] In order to maintain a uniform tension in winding a web on to a roll driven by a motor through an adjustable magnetic clutch, the clutch current is adjusted as a function of the difference between the rotational speed of the roll and the linear speed of the web, and is also adjusted to take account of such things as starting, accelerating to operating speed, stopping, and friction effects, and to maintain the tension when the roll is stationary. As shown, a web 11 is advanced by a roller 14 driven by a motor 41 through a magnetic clutch 38 and is wound on to a mandrel 16 driven by a motor 17 through a magnetic clutch 18. Tachometergenerators 19, 20 driven by the rolls 14, 16 supply signals to an inverse speed generator 21 which supplies an output signal, which is inversely proportional to the ratio of the speed of mandrel 16 to the speed of roller 14, through a tension adjuster 32 (by which the desired tension level is set) to a clutch voltage controller 22 so as to increase the torque with increasing web roll radius. Change in the torque requirement during acceleration and deceleration is controlled by an acceleration-deceleration compensator 31 which is a detectoramplifier adapted to transmit to the clutch voltage controller 22 a signal proportional to the rate of increase or decrease of the output signals of the tachometer-generator 19. A friction compensator 25 is a manually-adjustable voltage divider feeding a portion of a bias voltage available from a supply A to the clutch voltage controller 22. As the friction generally decreases as the speed of the winding unit increases, a R.P.M. compensator 34 which derives a signal from the tachometer-generator 20 provides a gradually diminishing bias as the diameter of the web roll 12 increases. To increase the torque on starting a forcing torque compensator 29 provides a direct current impulse of preselected magnitude and duration. The magnitude of the impulse is controlled by a diameter-sensing potentiometer 36 to increase the magnitude as the size of the roll 12 increases to give a greater starting torque. A standing tension compensator 27 transmits to the clutch voltage controller 22 a portion of a bias voltage from a supply D and is operative during a stall or standing sequence to maintain a torque sufficient for the required tension of the web. A taper-adjuster 33 is a potentiometric device transmitting to the clutch voltage controller 22 a portion of a bias voltage from a supply C. The taper adjuster 33 controls the tension pattern, i.e. the change in tension within the roll from the core to the periphery. When adjuster 33 is set at a zero setting the roll is given a constant tension. The adjuster 33 includes a potentiometer Y responsive to adjustment of the tension adjuster 32 to ensure that the taper bias signal is a fixed percentage of the signal from the tension adjuster 32.

Abstract: 1425766 Faulty memory replacement INTERNATIONAL BUSINESS MACHINES CORP 2 May 1973 [1 June 1972] 20961/73 Heading G4A Memory cell drive signals derived by decoding address signals are routed to select either a respective group of memory cells or a replacement group in accordance with the setting of a bi-stable latch. The memory system comprises several modules each containing an array of integrated circuit memory chips one of which, 11, is shown. A particular chip is selected conventionally and row 30-32 and column 33-35 address signals applied thereto. The memory array comprises word lines 22 and bit lines 21 and a redundant bit line 29, it being stated that a redundant word line can be provided as well as or instead of the redundant bit line 29. The bit line address signals are decoded at 24 and fed to the bit lines via respective transfer circuits 25. A transfer circuit associated with one of the bit lines 21 is shown in Fig. 2. A chip select signal on line 17 switches power (3À6 volts to nodes A and B in a bi-stable circuit formed by metal nitride oxide semi-conductor transistors 53, 54. If the redundant line 29 is not to be used, 3À6 volts is applied at inputs 61 and 63 and the bi-stable is set with transistor 54 conducting when bit decoder 24 supplies a select signal. This signal is thus routed via transistor 57 to bit line 21. However if bit line 29 is to be addressed in place of line 21 3À6 volts is applied at 63 and 0 volts at 61 whereupon transistor 53 conducts and line 29 is selected via transistor 59. The bi-stable may be latched semi-permanently by applying a high voltage to input 63 or 61 (depending on the state required). This voltage stores a charge in the parasitic capacitance of the appropriate transistor 53, 54 to lower its conduction threshold. The parasitic charge is stored for long periods even when the bi-stable is not powered so that the occurrence of a selected signal from chip select device 17 and bit decoder 24 automatically selects line 21 or 29 depending on the latched state of the bi-stable. Once latched the bi-stable state may be reversed and latched by applying a high voltage to the other input 61, 63. The arrangement allows bit lines to be tested for faults and replaced by a redundant line and a previously replaced line to be reconnected at any time. The complete circuit 11 including the memory array, the redundant cells, the address decoders, and the transfer circuits 25 may be formed on a single substrate.

Abstract: 1449084 Making silencers for gas or liquid flow BARRY WRIGHT CORP 13 May 1974 [15 Aug 1973] 21111/74 Heading B3A [Also in Divisions G2-G3 and F1] A noise reducing fluid flow device for gases or liquids comprises a housing 4 defining a passageway for carrying pressurized fluid across which an element 6 extends fully, and engages and is frictionally gripped by the internal surface of the housing, the element 6 being of a knitted metal wire mesh fabric that has been either rolled up or folded and, thereafter, compressed and moulded into a self-supporting porous mass with the wire threads of the fabric intermingled and forming a myriad of spring wire portions that are randomly oriented in the mass. A second element 8 of compressed knitted metal wire mesh fabric may be provided. Element 8 is formed outside the housing 4 and pressed in; element 6 may either be formed outside or inside housing 4. The housing is of a softer material (e.g. aluminium, aluminium alloy, polypropylene or epoxy resin) than the knitted fabric which may be of stainless steel, aluminium or nickel-chromium alloy so that portions of the wire abrade or cut into the interior surface of the housing, improving the grip between the parts. In Fig. 7 (not shown), the silencing elements (94A), (94B), may be in contact or spaced apart. Manufacture of the silencing element.-A tube of knitted metal wire mesh fabric (Fig. 4, not shown) is flattened to produce a two ply ribbon, which is rolled up or folded and then inserted into housing 4 with the width of the ribbon parallel to the housing axis. The element 6 is then formed in situ between an elongate piston member 66 of a piston assembly 66, 68, 70 and slidable mould element 38 and cylindrical extension 50 of the base 34 of a mould assembly. The upper end of extension 50 has a peripheral groove at 54 so that the end of element 6 is recessed with respect to the end of the housing 4. The extent of compression of the rolled up or folded wire mesh ribbon is determined by the length of the peripheral flange 82 of piston head 68. To ensure that the rim 20 of the element 6 is of sufficient density (as great as or greater than the rest of element 6), it is preferable to roll the flattened tube of wire mesh fabric so that the inner turns are axially displaced relative to the outer turns and insert the roll into housing 6 with its concave end facing the slidable mould element 38.

Title: Apparatus and method for handling and sorting articles
IPC: A61J3/07
Filed: 1972-05-05
Abstract: 1330099 Sorting elongate articles PARKE DAVIS & CO 5 May 1972 [6 Oct 1971] 21180/72 Heading B2H A method of soring standard-length and overlong elongate articles broader at one end than at the other, e.g. pharmaceutical capsules with separate cap and body parts which telescopically join together, comprises moving the articles downwardly in single file along an inclined slide formed by a rotating roll and a juxtaposed member, the roll and member being contoured to provide a drop hole at a predetermined position thereof, allowing the standard-length articles to fall end first under gravity through the drop hole, and preventing overlong articles from pivoting sufficiently to drop end first through the hole. In the embodiment shown in Fig. 2, the inclined slide is formed by a pair of rotating rolls 18a and 18b driven by a belt passing around grooves 20 so that the surface regions of the rolls nearest to each other each move upwardly to prevent the articles being nipped by the rolls. The contours of the rolls and their spacing is such that any capsule bodies A drop through a space 32a and any caps B fall through a space 33, while complete capsules both standard-length and overlong, pass to the drop hole 34. At this point the standard-length capsules pivot about the surfaces of the roll defining the edge of the drop hole and fall end first through said hole. The overlong capsules are prevented from pivoting sufficiently to pass end first through the hole by a pair of fingers 35 mounted below and slightly upstream of the hole. They therefore continue to move down the inclined slide and are discharged from the end thereof. The rolls 18a and 18b may be parallel or the space between them may gradually widen in the direction of travel of the capsules. Their spacing may be adjusted by means of a conical cam 15 which bears against arms 14 supporting the rolls. Advancing a wheel 17 towards an end wall 12 advances the cam which then pushes the arms 14 further apart against the action of springs 14a. Alternative constructions for the inclined slide include a rotating roll in combination with a stationary roll, or a rotating roll in combination with a stationary plane or curved surface.
