Title: Rail vehicles with powered bogies
IPC: B61F5/02
Filed: 1965-06-11
Abstract: 1,080,769. Railway vehicle undercarriages. SCHWEIZERISCHE LOKOMOTIV - UND MASCHINENFABRIK. June 11, 1965 [June 11, 1964], No. 24869/65. Heading B7L. In a railway vehicle, a powered bogie 3, Fig. 1, is connected to the vehicle body 1, for the transmission of traction or braking forces, by two tie rods 8 v , 8 h  the axes of the rods intersecting the central vertical axis of the bogie frame at a point P, at or near the level of the upper edges of the rails, and at least one end of each rod is connected to the body or bogie by a resilient element, e.g. 10 v  or 10 h , having a non-linear characteristic, the rods being under tension in all operating conditions. As described with reference to Fig. 7 (not shown), the spring characteristic becomes steeper with increased loading. Referring to Fig. 1, and Fig. 3 (not shown), the spring (10 v ) or (10 h ) comprises a rubber ring (11) of conical form embedded between the conical surfaces of metal rings (14), (15) and vulcanized to them. The element is embedded in a shell (16) having at its centre a hole (17) for the passage of the rod (8). The shell is welded to carrier members (18) connected to a base plate (19) welded to the vehicle body. The ring (14) abuts a sleeve (20) on the rod (8), the sleeve (20) having a wide part (21) engaged by a nut (25) locked on the threaded end of the rod (8) by a pin (24). A spherical surface (22) on the sleeve (20) can abut a coacting surface (23) on the shell (16). The element (10) when unstressed is of hollow truncated form whereby the ring (11) is first subjected only to shearing forces until its free surfaces (27), (28) begin to bear on the plate (21) and the interior of the shell (16) respectively. Thereafter the rubber is subjected to pressure loading which increases continuously since continuously larger areas of the surfaces (27), (28) bear on the plate (21) and the shell (16). In another embodiment the resilient elements are inserted between the bogie and rods, the latter being connected to the body by links, and the rods are horizontal. The element 11 may be replaced by concentric rubber elements in stepped formation as described with reference to Fig. 4 (not shown). Alternatively, the element 11 may be replaced by an evolute spring, a helical spring in which the coils are of varying pitch, Fig. 5 (not shown), or a spring of truncated conical form. In a further embodiment a helical spring acts between a pivot connection of a two-part tierod, and the vehicle body is described with reference to Fig. 6 (not shown).

Title: Improvements in regenerative heat exchange apparatus of the rotary type
IPC: F28D19/04
Filed: 1964-06-16
Abstract: 1,073,014. Thermal regenerators. SVENSKA ROTOR MASKINER AKTIE BOLAG. June 16, 1964 [June 21, 1963], No. 24899/64. Heading F4K. A thermal regenerator having a rotor which includes a central rotor post 18, is characterized by supports 38 secured to the rotor post and supporting the rotor via pivoted links 46, the rounded upper ends 52 of which engage hardened metal pads 44 on an annular flange 42 mounted inside the inner shell 14 of the rotor. The location of the flange 42 is chosen to obtain optimum sealing between the rotor and adjacent ducts with regard to thermal expansion under operating conditions. Radial guide members 56 permit differential radial expansion but restrain relative rotational movement between the central post 18 and the shell 14. Heat insulation 54 keeps the inner and outer shells at about the same temperature and keeps the post and supports and guides relatively cool. The rotor post may therefore be of low cost carbon steel while the rotor proper is of heat-resistant stainless steel.

Title: Apparatus for spinning filaments
IPC: D01D5/32
Filed: 1963-06-24
Abstract: 972,948. Spinnerets. MONSANTO CO. June 24, 1963 [June 25, 1962], No. 24993/63. Heading B5B. A spinneret suitable for making conjugate filaments is supplied axially with a spinning composition or solution from a source 25, and radially with a second spinning composition or solution from the source 21. The first spinning solution passes through the spinneret plate 11, and the small discrete streams of spinning solution so formed are converged in the chamber 12 by the radially inward flow of the second spinning solution. The combined solutions pass through the restriction in the chamber to a second spinneret 29. The flow of the combined solutions is laminar owing to the high viscosities and slow rates of flow of the two spinning solutions. Hence the central portion 41 of the bundle of filaments emerging from the spinneret 29 is derived from the axially-supplied spinning solution from source 25, the annular band of filaments 42 is derived from the radially-supplied spinning solution from the source 21, and the annular band 40 comprises composite filaments. Different spinning solutions may be fed in through the holes 20 and 22, so that different filaments in the band 40 will be made up of different combinations of spinning solutions. On annealing the tow the composite filaments curl and twist, so deflecting the other filaments from their normal linear configurations and tending to hold the tow together, facilitating subsequent processing.

Title: Improvements in or relating to waterproof fabrics and their manufacture
IPC: D06M15/693
Filed: 1928-09-01
Abstract: 296,450. British Celanese, Ltd., (Assignees of Dreyfus, C.). Sept. 2, 1927, [Convention date]. Special fabric bases.-Waterproof fabrics are made by coating an open-mesh fabric made from organic cellulose derivatives, for example cellulose acetate, with a waterproofing composition such as rubber solution. Owing to the non- absorbent character of yarns made from cellulose derivatives, the solution fills the interstices of the fabric and produces a smooth coating. The waterproofing composition may be of any suitable kind, solutions containing rubber being specially suitable, and may be applied by spraying or in any known manner. The fabric may contain yarns consisting of cellulose esters or ethers, such as cellulose formate, acetate, propionate, &c., or methyl, ethyl or benzyl cellulose &c., either alone or in combination. The open-mesh fabric used may be georgette and muslins such as voile, ninon, chiffon, &c., or knitted or other foraminous fabrics.
Patent GB-421212-A (GB)
Title: Improvements in or relating to systems for transmitting a plurality of sound effectssimultaneously
IPC: H04B3/20
Filed: 1933-09-11
Abstract: 421,212. Reproducing music. WESTERN ELECTRIC CO., Ltd., Bush House, Aldwych, London.-(Electrical Research Products, Inc. ; 195, Broadway, New York, U.S.A.) Sept. 11, 1933, No. 25156. [Class 40 (iv)] In a sound-recording system in which sound (e.g. voice and background) currents are transmitted along separate channels and subsequently made to produce a combined effect, currents in one channel upon exceeding a predetermined level cause the introduction of a fixed degree of attenuation in the sound effects in one or more other channels no further effect being produced by a rise in the level in the first channel. As shown, Fig. 3, currents from the voice channel, after passing an amplifier which discriminates in favour of the frequencies from 200 to 2000, are rectified and energize a relay 46 which connects a battery 47 in a potential-divider circuit 50, 51 and so reduces the bias on a photo-electric cell 24 influenced by the film 22 carrying the background record. Alternatively the operation of 46 may be made to cause a portion of the light to be screened off or the brightness of the lamp 23 to be diminished. Switching clicks are absorbed by a resistance-condenser circuit 52, 53. The speed of operation of the arrangement is governed by the values of condensers 54, 55 and resistance 50. With values given in the Specification the background currents are attenuated À08 seconds after 46 operates and are not fully restored until À5 seconds after it falls back. In a modification, Fig. 4, in which the additional attenuation may be imposed only on the higher frequencies in the background channel the sound frequencies in that channel are, with the keys A, B in the position shown, separated by the condenser 70 and inductance 71 into two channels. Currents in respect of voltages developed across condenser 70, which are mostly due to the lower frequencies, flow in a circuit involving the upper primary of transformer 74 and are thus passed on independently of the attenuator. Higher frequency voltages developed across inductance 71 cause a current flow through condenser 85 and an attenuating network to the input transformer of a push-pull amplifier 93, 94 which neutralizes the loss introduced by the network. Currents in the speech channel cause the operation of relay 46 which reduces the gain of the amplifier 93, 94. The operating and restoring speed is governed by the values of resistance 109, and of the condenser selected from a group 114 .. 118 to shunt it. With values given in the Specification the operating time is from À01 to À1 seconds and the restoring time from À15 to nearly 2 seconds. With the keys A, B in their operated positions, the whole of the back-ground band is subject to the operation of the attenuator. Relay 46 may be made to suppress the background completely as by opening the transmission path. Either path may include means for delaying the sound effects.

[Also in Group XXXV] To enable a barometer to be read more accurately, its upper portion is formed helically, Fig. 7, or in zigzag arrangement, or in tree-branch style, Fig. 6, said upper portion for a mercury-filled barometer being a zone between about 25 inches and 33 inches above the level of the mercury in the base. The upper and lower ends of the helical arrangement may be mounted in bearings 1 such that the barometer can be rotated about its vertical axis. Fig. 11 illustrates a helically shaped barometer of varying diameter, the larger diameter being in the range more usually seen; this form conserves mercury. A circular scale is provided inside the helix. To maintain a constant level in the mercury reservoir 7, a metallic point 14, Fig. 7, is used. When the mercury level contacts this point an electric motor 13 causes a reservoir 9 to be lowered, the reservoir 9 being connected to the reservoir 7 by a tube 8. When the mercury level in the reservoir 7 falls so that it no longer contacts the point 4, the electric motor causes the reservoir 9 to rise. This action maintains a constant level in the reservoir 7. As an alternative to the point 14, a float may be provided on the surface of the mercury, said float carrying means for actuating contacts controlling the electric motor.

Abstract: 518,630. Coin-testing devices in coin-freed machines. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and ROBINSON, M. H. Aug. 30, 1938, No. 25398. [Class 27] In coin-freed machines in which coin-testing devices 3, 5 and 7 operate in sequence with provision for directing rejected coins to an outlet shoot 13 leading to a return tray 14, delivery can be expedited in special circumstances by setting the delivery-apparatus in action after any particular coin-test insead of at the end of the series. During normal working the passage of the accepted coin down the final shoot 8 trips the lever 24 and thus closes contacts 26. This initiates delivery. For special circumstances, for example, the issue of tickets during rush hours, a similar apparatus 22 may be installed after the tester 5 or at any other point in the system. In such a case the coins pass through the remaining tests after delivery of the article. Rejected coins in such cases are retained in the shoot 13 by the pivoted arm 28 which is raised automatically whenever the advance delivery apparatus 22 is set in action. A modification is 'described in which the transfer from deliveryapparatus 24 to 22 is made by operating a twoway switch from a remote point.
