Title: Improvements in and relating to felt articles
IPC: A42C1/02
Filed: 1946-05-07
Abstract: 611,769. Felt. BOHM, V., and ROWLAND, P. H. May 7, 1946, No. 13824. [Class 42(ii)] Tapered felt articles such as hat bodies are produced by making flat felt sheets having felted portions corresponding in size and shape with the developed or unfolded surface of the article to be formed, the edgings of this surface being unfelted or only slightly felted, the hollow article then being formed and closed along the unfelted or slightly felted edges by felting the latter together. Webs, formed, in the case of wool, by carding, or in that of hair or fur, by blowing, are laid crosswise, one over the other, and felted in a flat felting machine provided with hardening plates or shoes profiled to correspond to the flat development of the hollow body to be made. This produces a sheet 1 having circular, oval or multiangular felted portions 2 with unfelted sectors 3 and separated by unfelted portions 4. The felted portions 2 are then separated, together with narrow unfelted edges 6, from the remainder of the sheet; the edges 6 are then superimposed and felted together in a machine engaging only the unfelted portions. The edges may be grooved or bevelled where they overlap. Different qualities or colours of fibre may be used on the two sides of the felt.

Title: Electronic sound production
IPC: G10H5/00
Filed: 1976-04-08
Abstract: 1521184 Electronic musical instruments CMB COLONIA MANAGEMENT-UND BERATUNGSGES mbH & CO KG 8 April 1976 [8 April 1975] 14354/76 Heading G5J The invention concerns the generation of sounds electronically, the sounds having a predetermined timbre over a range of pitch. Pulse strains are generated which have a pulse width which is constant over a pitch range and two or more such strains are combined so as to form for example a waveform like Fig. 2 which is stated to have an overtone structure like Fig. 3 with amplitude minima giving a formant character. The pulse width remains constant over an interval of a fifth at least or more conveniently an octave. At either end of the interval the pulse width is changed either instantly or over a range of a semitone to half or twice its previous value. In mimicing particular instruments the changes may be arranged to occur at natural breaks in the scale as for instance between notes played on different strings. Two examples of instruments employing the invention are described. In a first (Fig. 4, not shown) the sound of a simple monophonic instrument or a voice is received by a microphone. The amplitude information from the received signal is used to control the amplitude of the output. The waves of the signal are squared in a trigger circuit, frequency divided or multiplied as necessary and used to trigger a pulse generator whose output pulse width is constant over a range of received notes. Further filters are employed to simulate the propagation characteristics of the instrument being mimiced. In the other instrument (Fig. 5, not shown) the frequency information is derived by key operated switches which control the pulse generator; a blow tube with a microphone provides the amplitude and phase modulation signals which control the output of the pulse generator.

Abstract: 395,492. Composite photographs. BRIEL, C. G., 1510, Melrose Street, Chicago, U.S.A. May 24, 1932, No. 14726. Drawings to Specification. [Class 98 (ii).] A process of producing a composite picture embodying two or more different parts comprises producing an image of one component on a sensitive film, of a density sufficient to exclude transmitted light during the second exposure, exposing the film to the second component, treating this image to produce a density corresponding to that of the first image and treating the composite image so formed to make the image details visible by reflected or by transmitted light. The originals used may be natural scenes or objects or photographic negatives. In carrying out the process, a film is first exposed to the foreground component and the image developed to opacity. An image is then made from the background component in the undeveloped silver bromide and developed to opacity. A stop-bath may be used after either development. The composite image illuminated from the front may then be copied on a fresh sensitive surface. Alternatively, it may be treated with potassium permanganate and sulphuric acid or with chromic acid, followed by an acid sulphite bath, to remove the silver image, and an opaque backing applied, the undeveloped silver bromide forming an image which may be copied on a sensitive film. The undeveloped silver bromide may also be developed and the image copied by transmitted light.

Abstract: 1496565 Positioning scanning heads photoelectrically ROBERT BOSCH GmbH 11 April 1975 [13 April 1974] 14910/75 Heading G1A [Also in Division G3 and G5] A method of obtaining a signal representing the deviation between a scanning light beam and an optically contrasting signal track on a carrier surface, comprises: arranging that the beam is focused by a lens and directed to form a spot on the trackcarrying surface such that at least the track width is filled by the spot; and arranging two mutuallyadjacent photo-cells spaced from the focus and on opposite sides of the optical axis of light transmitted through the surface, so that the difference between the photo-cell signals represents the deviation of the beam from the centre of the track. A laser beam 4 reflected by a mirror 6 is focused by an objective lens 3 at a point behind the surface of a rotatable disc 1 carrying transparent signal tracks 21-23 which may be of 1 Ám width and 3Ám spacing. The height of the objective 3 above the track 2 2  is stabilized by an air bearing provided by an air supply tube 7 connected to a housing 8. The light falling on one or other of two photo-cells 5 1 , 5 2  positioned below the disc 1 and on opposite sides of the optical axis in a line radially of the disc 1, is obscured to an extent depending on the deviation of the optical axis from the centre of the track 2 2 , the boundaries of the track acting like Foucault knife-edges. Differential signals from the photo-cells 5 1 , 5 2  may be used to initiate corrective action, e.g. by rotation of the mirror 6. The lens 3 may be an astimatic or slightly curved cylindrical lens arranged so that the narrowest cross-section of the beam lies in the plane of the carrier; or it may be arranged so that its optical axis is inclined to the normal to the carrier surface.
