Type-bars; holders for type-bars.-Each end face of a printer's slug is provided with a recess embodying a ramp face extending from a lower part of the recess obliquely upwardly into the slug. The slug or type-bar 10, Fig. 1, is provided on its side faces 11 with projections 15 which are tapered downwardly so as to blend into the edges of the base 13, in order that bars can be assembled on a curved holder without the use of tapered furniture. The end faces 12 of the type-bar are provided with recesses 18 embodying ramps 19 for positive engagement by a holder. The fudge-box 16 is provided with a stationary wedge-shaped projection 21 and a similar movable projection 20 to engage the ramps and press the type-bar downwards. Moulds.-A mould for casting type-bars 10 is secured to the mould-wheel of a type-bar making machine, and is provided in the top and bottom of the mould cavity with tapered recesses 33, Fig. 7, for casting the projections 15. For casting the recesses 18, the mould is provided with slides 34, 35 having inclined ends 38 corresponding to the ramps 19. On ejection by the mechanism 45, the ramps 19 force back the slides against the action of springs 41, which cause the slides to snap back after the type-bar is ejected. In one form, the springs 41 are connected by a taut wire 49 contacting rollers 52 on the top of the mould, and passing through an eye 50 on a slide 51. During casting, the slide is pushed back by the matrix vise 53, so that the force of the springs is increased to prevent pushing out of the slides under pressure of the liquid metal. The springs are attached to levers 39 which engage the ends of the slides and are pivoted to the mould base. Alternatively, the inner ends of the springs may be connected to the top part 31 of the mould, and the wire 49 and its associated mechanism be omitted.

Title: Improvements in or relating to air volume governors for centrifugal fans
IPC: F04D27/02
Filed: 1920-04-12
Abstract: 165,561. Spencer & Co., Ltd., and Frame, W. J. April 12, 1920. Regulating.-The volume of air passing into a multi-stage fan is regulated by permanently creating an increase or decrease of pressure from the normal and operating an inverted gasometer vessel by a predetermined change in this variation from the normal pressure, thereby actuating a regulating-valve. The air drawn in by an exhausting- fan a enters bv an inlet pipe b and escapes by a pipe c provided with a restricting orifice to create a difference of pressure between the air in the fan at the pipe connection h and the atmosphere. The pipe h leads to the inside of a gasometer vessel f provided with guides g adapted to slide in a vessel e in a liquid seal. The vessel f is adjustably weighted, and when the pressure in the fan rises above a predetermined value the rise of the vessel f actuates a valve k through a spring i and rod j to close the valve. The outer vessel e is in this case connected to the atmosphere. A Venturi tube may be used instead of a restricting orifice, the inner gasometer vessel being connected to the static end of the tube and the outer vessel to the throat of the tube. Whether used with exhausters or blowers the inner vessel is connected to the higher'pressure side of the restricting orifice or Venturi tube.

Title: Method of avoiding disturbing extraneous noises in talking machines
IPC: G10K13/00
Filed: 1928-04-05
Abstract: 315,333. Ohagen, H. April 5, 1928. Drawings to Specification. Eliminating needle-scratch by using damping- means during reproduction from loud-toned records.-A method of eliminating needle scratch in the reproduction of sound from gramophone records consists in (a), using records in which the amplitude of all the recorded sounds is such that, if reproduced on a gramophone in the ordinary way, the needle scratch would be masked by the sounds intended to be heard, but the latter would be too loud for satisfactory audition, and (b), during the reproduction, using a damping device which tones down the sounds intended to be heard, to a suitable amplitude, whilst it damps out entirely the extraneous sounds. Any suitable damper may be used, such as a plate fitted over the mouth of the horn, or a cone, lined with felt, inserted in the horn.

Filed: 1972-03-28
Abstract: 1366341 Carpets DUNLOP Ltd 28 March 1972 [13 April 1971] 10652/71 Heading A4S [Also in Divisions B5 and B6] A carpet tile consisting of a backing layer to which is attached a fibrous surface layer is provided on its surface with an enclosed pattern defined by one or more cut lines, the cuts extending into a proportion of but not completely through the thickness of the tile whereby that area can be subsequently cut out from the tile by cutting through the remainder of its thickness along the cut lines. Each cut-out portion can be transposed into another tile from which a similar area has been removed so that wherever two tiles are of different colours or textures a patterned effect is obtained. The backing layer may be rubber or thermoplastic resin to which is attached the fibrous surface layer, e.g. needlepunched fibres. The tiles may have a cellular backing layer. The carpet tile may be provided with a fabric or scrim reinforcement between the backing layer and the fibrous surface layer. The enclosed pattern may be cut on either face  of the tile, preferably in the back face . Where a reinforcement layer is provided the pattern may be cut through both the backing layer and the reinforcement layer. Preferably the tiles are cut through 75-100% of the backing layer. The tiles may also be provided with a pressuresensitive adhesive on their back face, protected by a sheet of release paper. Preferably the cut is made through the release paper, the adhesive layer and the required proportion of the tile thickness in one operation. Alternatively the enclosed pattern may be cut into the front face so that the release paper is uncut. In an example square carpet tiles were made having a filled rubber backing having a lightly waffled impression on its undersurface. The backing was laminated to a needle-punched nylon carpet layer. Enclosed patterns were cut into the backings of each tile to a depth of 95% of the thickness of the backing using a flexible steel strip cutter shaped to the desired pattern.
