Abstract: 1383123 Metal fibre felts; air laid mats WURTTEMBERGISCHE METALLWARENFABRIK 30 May 1972 25286/72 Headings D1N and D1R [Also in Division C7] A porous metal fibre sheet -is prepared by tumbling metal fibres in a rotating drumshaped screen, through the mesh or perforations of which the fibres fall to form a layer upon a support, applying an adhesive solution, depositing one or more additional layers of metal fibres and drying to remove the solution. A plurality of layers of adhesive solution may be applied between layers of metal fibres. As described graded chrome nickel steel fibres of 5mm length and 0.1 to 0.2 mm diameter were placed in a distribution drum having its curved surface provided with 1mm openings that occupy 30% of the surface. The drum was rotated at 50 r.p.m. whilst being guided back and forth over a carrier sheet, thereby producing a uniform deposition of fibres. A vibrating screen may be placed between the distribution drum and the carrier sheet. After 4 layers had been deposited a solution of a copolymer of acrylic resins was sprayed on, additional fibres deposited and the mat dried. The adhesive may contain pigments in the form of fine metal powders metal oxides, carbon black, active charcoal and graphite. The mat may be compacted. The mat was then sintered at 1250‹C for 2 hours under a hydrogen atmosphere. The product had a pore volume of 85%; a pore volume of up to 98% is possible. An alternative apparatus involves a continuously movable conveyor belt, a vibrating screen and one or more non-displaceable distribution drums.

Patent GB-1159836-A (GB)
Title: Receiving Signal Distributor for a High Speed Teleprinter of the Start-Stop Type
IPC: H04L13/10
Filed: 1967-06-02
Abstract: 1,159,836. Telegraphy. ING. C. OLIVETTI & C. S.p.A. 2 June, 1967 [7 June, 1966], No. 25490/67. Heading H4P. A Start-Stop telegraph receiver distributer comprises selector levers 15-19, which are sequentially set to a position representing the received serial signal, and transfer levers 28-32 which simultaneously position code bars 52 according to the setting of the selector levers. Some of the transfer levers are moved directly by the selector levers, while others are moved only a certain time after the setting of the selector levers. The delay in moving these levers allows time for the setting up of the print selectors after reception of a code signal. The distributer, Fig. 1, is similar to that described in Specification 1,159,835, Disc 4 rotates once in response to a Start bit. Wedge 13 is also positioned by the received bits that wedges 20 on the selector arms are guided above or below wedge 13 as they are carried past it. The wedges 20 are then locked in position above or below guide 5. In a 5-bit signal bits 3-5 actuate selectors 17-19 which directly position transfer levers 30-32. Levers 15, 16 are positioned by the first two bits but are coupled to the transfer levers 28, 29 by way of lost motion mechanism 41, 45 so that these transfer levers are not yet set. Pins 48, 49 on the wedges 20 of the levers 15, 16 are cammed by surfaces 46, 47 on guide 5 so that at the time that selector levers 18, 19 are being set the selectors 15, 16 are given an additional movement which is sufficient to set transfer levers 28, 29. Because of the delay in setting bits 1 and 2 on the transfer levers a signal stored on the transfer levers can be used to set the printer code bars at any time up to reception of bit 3 of the next signal. The position of the arm 34, Fig. 2, of each transfer lever is sensed by a corresponding pair of slides 65, 66 which, after reception of the fifth bit, are urged downwards by a lever 61 under the action of cam 55. One or other slide of each pair is prevented by arm 30 from being moved downwards, and shoulders 69 thus rotate the corresponding code bar 52 to a position dependent on the bit-sense.

Title: Improvements in or relating to adjusting devices
IPC: G02B21/24
Filed: 1961-07-14
Abstract: 960, 846. Microscope adjustments. C. REICHERT OPTISCHE WERKE A. G. July 14, 1961 [July 16, 1960], No. 25695/61. Heading G2J. [Also in Division F2] Coarse and fine relative movement of two parts of a microscope is effected by operation of a single knob, by provision of a bearing piece supported on one part by a mounting which permits pivotal movement relative to said part, a drive connection between a shaft carried by the bearing piece and an intermediary member secured to the other part whereby rotation of the shaft about its axis effects coarse relative movement of the two parts, and means associated with the mounting for moving the drive connection in response to pivotal movement of the bearing so as to effect fine relative movement of the two parts. In the microscope shown in Fig. 1, a stagecarrier 6 is moveable in a dovetail guide in a box 2 carried by the base 1, the carrier 6 supporting, between pivot pins 12, 13, a rack 14 meshing with a pinion 20 on a shaft carried by a nut 19, which threads on to a screw bolt 15 on the base 1. By rotating the shaft about its axis, coarse movement of the stage is effected; fine movement results from the movement of the shaft about the axis of the screw bolt 15, such movement causing the nut 19 to move axially along the bolt 15. Instead of the rack 14, the drive between the shaft and the carrier 6 may be effected by a cable attached at one end to the carrier and at the other end to a drum mounted on the shaft, which may be supported by a member forming a push-fit on to a projection of the base and having a roller engaging an inclined surface on the base so as to cause the member to move vertically when it is rotated about the axis of the projection. In another form, Fig. 4, a rack 39 pivoted at 40 to the stage-carrier 6 is spring urged at 41, 42 into engagement with a pinion 35 on the shaft, which is carried by an angled member, pivoted at 37. Fine adjustment is effected by movement - around pivot 37, while coarse adjustment results from rotation of pinion 35 about its own axis. Finally, there is described, an arrangement in which the shaft has a drum cable connected to the stage-carrier 6, the shaft being mounted in a support which can pivot about an axis so as to raise or lower the point at which the cable is connected to the drum.

Abstract: 453,247. Optical sound - recording apparatus. HANSEN, S. S., and WENDT, T. M. E., Filmstaden, Rasunda, Sweden. Sept. 16, 1935, No. 25706. Convention date, Oct. 22, 1934. [Class 40 (ii)] A light valve for recording sound on a film, comprising two strings or strips vibrating in accordance with the sound for modulating the light exposing the film, is characterized in that the strings &c. are spaced apart in the direction of the rays of light, and are in separate magnetic fields. The distance between the strings or strips is preferably at least ten times the diameter of each string or the width of each strip. In the construction shown, tensioned strips 14, 15 of rectangular cross-section are located as shown in air or oil gaps 9<a>, 10<a> between the polepieces 9, 10 and 10, 11 of an electromagnet, the strips intercepting a light beam which passes from a source 1 through bores in the polepieces and is focused on a film 8. A lens system 2, 3, 4 is mounted in the bores, the lens 4 forming an image of the strip 14 in the plane of the strip 15. The strips 14, 15 are connected in series with the secondary 23 of a transformer to which microphone currents are fed, and the magnet is energized by a constant current in coils 12, 13. Alternatively, audio-currents may be supplied to the coils 12, 13, the strips being fed with constant current. In a modification, the strip 14 is placed below the level of the strip 15, i.e. on the opposite side of the beam, the lens 4 being then arranged in the polepiece 11, and the windings of the coil 12 recessed. The cooperating edges of the strips may be curved. Instead of arranging that the cross-section of the light beam is varied by the strips, as in the construction shown, the intensity may be varied by providing the strips with members of uniformly decreasing transparency which modulate the light passing therethrough.
