Abstract: 1400749 Web formers: Non woven paper makers felt ALBANY INTERNATIONAL CORP 5 Dec 1972 [6 Dec 1971] 56097/72 Headings DIN and D1R [Also in Division B5] A papermakers felt is made by lapping a carded web in a plurality of layers at an angle of 85-45 to the direction of travel of a floor apron and consolidating the web into a sheet, the edges of the sheet are then feathered and it is delivered to a second lapper where it is again lapped in a plurality of layers at an angle of 10-40 to the direction of travel of a floor apron and again consolidated into a base fabric on a carrier, which carrier is then peeled from the base fabric and a web is added to the base fabric, finally the felt is stretched lengthwise to orient the fibres in the base fabric substantially lengthwise. Apparatus for producing the felt comprises a carding engine delivering fibre web to an apron 11 and thence a primary lapper top apron 15, the primary lapper 13 operating to produce a multilayer web which passes through a consolidating means e.g. rollers 19, 20, 21 to an intermediate apron 23 from whence it travels vertically via aprons 24, 25 to a further intermediate apron 26 which delivers the web to a feed-through apron 29 and thence through an edge feathering means 32 to a second lapper 30 which is followed by a further consolidating means e.g. a pre-needling machine 37, the above mentioned apron 11 is movable to a position which by-passes the first lapper and supplies web directly to the feed-through apron 29. The fibre sheet is formed into a substrate by deposition on a scrim carrier 43, Fig 2C, in multiple layers which are needled at 46 and, When suitably consolidated, the scrim is peeled away. A web, produced in the by-pass position, is layed on the surface of the substrate and needled thereto, Fig 3, the web fibres being orientated transversely of the felt belt so formed. The belt produced by the described method and apparatus comprises a base of lapped layers of web with its fibres oriented lengthwise and consolidated by needling and to which a further web is needled, the further web fibres being oriented crosswise. The fibres may be a blend of polyamide, polyester and polypropylene fibres, the latter being fussible to allow heat setting of the belt. Proportions lengths and deniers of the component fibres are given. The belt may be bonded by resin treatment. After completion of needling the felt is washed and stretched to its proper operating tension and length in a conventional felt dryer.

An electromagnetically loaded vacuum regulator has a diaphragm 14 carrying an armature 12 and a valve 18 which opens to connect the regulated vacuum to atmosphere via conduit 21, chamber 16, valve 18 and a chamber 20 at atmospheric pressure, when the regulated vacuum exerts more force on the diaphragm than the armature 12. Also a second valve 24 is provided to open communication between vacuum source 22 and conduit 21 should the regulated pressure exert less force on the diaphragm than the armature 12. Thus the regulated pressure corresponds with the flux ' _ generated in the electromagnet at any instant. A brass spring 25 of dished shape (Figs. 2A, 2B, not shown) prevents armature 12 making contact with core 10. In a modification (Fig. 3, not shown) this brass spring is dispensed with and the armature is supported by a diaphagm spring (27).

Title: Pulse counting system
IPC: H03K5/26
Filed: 1971-12-06
Abstract: 1363300 Measuring displacement ALLMANNA SVENSKA ELEKTRISKA AB 6 Dec 1971 [7 Dec 1970] 56475/71 Heading G4H From phase displaced pulse trains A, B (Fig. 1) representing the amount and direction of movement of a member, logic circuitry derives signals for incrementing or decrementing a counter R. As described, the pulses in the trains A, B are read into memory circuits V1, V3 at each clock pulse C1 from a generator CPG, the previous contents of these circuits V1, V3 being transferred to further memory circuits V2, V4. The output signals from all the circuits V1-V4 and their complements are compared in AND gates U1-U4, N1-N4, one of the first set giving a signal (when the member moves one increment in one direction) via an OR gate U5 and an AND gate U6 (primed by clock pulses C2 delayed from the clock pulses C1) to input RU of the counter R so that a pulse from OR gate O increments the counter. One of the second set N1-N4 similarly gives a signal when the member moves one increment in the other direction to decrement the counter. Since the clock pulses are short in relation to the pulses of the pulse trains A, B, errors due to disturbances in the pulse trains are reduced. If a disturbance occurs during a clock pulse, the count is corrected at the subsequent pulse. The pulses are derived from a disc (Fig. 3, not shown) having two tracks each comprising two slotted members extending over 90 degrees. The sets of the two tracks are phase displaced by 45 degrees from each other and sensed by two photo resistors, photo diodes or photo transistors. Modification.-One of the second memory stages V2 or V4 and some of the AND gates U1-U4, V1-V4 may be omitted.

Title: Improvements relating to position indicators and positioning apparatus
IPC: G05D3/20
Filed: 1968-12-11
Abstract: 1,247,537. Determining position. INTERNATIONAL BUSINESS MACHINES CORP. 11 Dec., 1968 [15 Jan., 1968], No. 58871/68. Heading G4H. Apparatus for controlling the movement of a member includes a transducer feeding pulses as the member moves via a gate 42 (Fig. 2) to a reversible counter 30, the contents of which may be used to derive a control signal to position the member. In the embodiment described for maintaining the inter-record gap of data on tape at 40 units, when a stop signal is generated at terminal 31 when the tape is moving with full velocity a bi-stable 41 is set to open gate 42 and allow pulses to pass to counter 30. Gates 33 are simultaneously enabled so that an output voltage representing the count is compared at one input of differential amplifier 35 with a bias signal at terminal 30 representing a count of 20, the motor driving the tape consequently being stopped after 20 pulses. If a forward signal is then received gate 42 remains open until 20 more pulses have been received from the transducer when a zero or full detector 45 is enabled to reset bi-stable 41 to set counter 30 to zero (via gate 46) and enable a read/write gate 50 via gate 48 provided a "full velocity" signal is received at terminal 49. The outputs of counter 30 are not applied to the differential amplifier 35 since the gates 33 are closed, the only signal applied being a bias signal at terminal 36. If alternately a reverse signal is received counter 30 is counted down to zero when read/write gate is similarly enabled. The outputs of counter 30 are held at 40 units during this time by gate 57 so that a signal representing - 20 units is applied to the amplifier 35. Logic circuitry (Fig. 5, not shown) is described to ensure that no output pulses from the transducer are gained or lost when the tape changes direction.
