Title: Improvements in or relating to swash-plate drives
IPC: F16H23/06
Filed: 1935-03-26
Abstract: 454,303. Swash - plate mechanism. STINNES, H. H., 1, Lichtensteinhalle, Berlin. March 26, 1935, No. 9326. [Class 80 (iii)] Relates to a swash-plate drive comprising three or more individual swash-plate units arranged side by side on a common shaft and with phase difference other than 180‹, the units being so mutually related as regards phasedifference and masses that a balance in any plane containing the shaft axis is produced, and consists in further relating the units, in so far as those parts of the swash rings which are constrained to move in a plane are concerned, that a balance transverse to the shaft, and therefore a complete balance are obtained. Three swash-plates b<1>, b<2>, b<3>, Fig. 1, are secured to one another and to a shaft a, and carry rings c<1>, c<2>, c<3>, each of which has pins d<1> ... d<6>, Fig. 2, engaging swivel blocks e<1> ... e<6> in pistons gl ... g<6>. The swash-plates b<1>, b3 are set at a phase difference alpha in opposite directions from the swash-plate b<2> and, if the weight of the central ring with its pins and parts connected thereto is W, that of each of the others is W sin alpha. The pins d<1>, d<4> are constrained to move in a plane by insets h, the other pins performing a lemniscatic movement. The additional balance, transverse to the shaft, is obtained by arranging that those pins of each unit which do not perform the lemniscatic movement are displaced angularly relatively to the non-lemniscatically moving pins of adjacent rings by an amount equal to the phase difference of the respective units.

Title: Improvements in or relating to blast deflectors
IPC: F42D5/00
Filed: 1965-03-04
Abstract: 1,249,851. Blast shields. C. S. CROSS (U.S.A. Army, Secretary of). 4 March, 1965, No. 9359/65. Heading F3A. In order to prevent the sympathetic explosion of a charge of explosive in response to the explosion of another charge of explosive in close proximity, a blast deflector shaped to divide or split a shock-wave resulting from the explosion of either of the charges is interposed between the charges. By this means, a number of charges placed in alignment may be ignited successively and independently without a chain reaction occurring due to sympathetic explosions. Apparatus for testing the effectiveness of the invention includes a blast deflector 10 mounted on a base 12, on which base 12 are also mounted two supports 16, 20, each of which carries a charge of high explosive consisting of a rectangular rod 14, 18, respectively. These rods 14, 18 are in line with their end surfaces 22, 24, respectively, facing the blast deflector 10. The deflector 10 consists of a rectangular block of blast resistant material upstanding from the base 12 with the corner edges 10b facing the respective charge surfaces 22, 24 and has the effect of dividing or splitting the shock wave emanating from either charge if it should explode, thus providing a degree of shelter which is adequate to prevent the other charge exploding by sympathetic explosion. The surfaces 22, 24 are preferably chamfered away from the splitting edges 10b which has the effect of reducing the destructive quality of the blast from an exploding charge. Thus, if charge 14 explodes, the resulting shock wave presents a front with a leading edge of comparatively mild intensity followed by an increasing intensity, in which case an object such as the deflector 10 in the path of the shock wave is subjected to a more gradual build-up of pressure than if the surface 22 was squared. If the surface 24 on the charge 18 is similarly chamfered, then the destructive tendency of the shock wave from the charge 14 on the charge 18 is further reduced since the chamfered surface tends to p'ough into the wave much as the prow of a ship ploughs into a water wave. The use of a blast deflector 10 has proven adequate to prevent sympathetic explosions between charges even where the ends of the charges are not chamfered, but by the use of chamfering either a greater degree of safety is obtained or the blast deflector 10 can be made smaller or with a lower degree of blast deflection.

Abstract: 1,081,017. Retractable undercarriages. ELECTRO-HYDRAULICS Ltd. March 5, 1965 [March 5, 1964], No. 9363/64. Heading B7G. A retractable aircraft undercarriage of the leading or trailing link type is retracted by swinging it rearwardly or forwardly, respectively, through over 180 degrees. The lever 56, on which the wheel 51 is mounted, is pivoted about a transverse axis 57, and has a crank arm 59 connected by a link 60 to a bracket on an actuating rod 62. When the aircraft takes off the wheel falls to the free-in-air position 51 1 , and the actuating rod may then be operated to rotate the lever until the wheel is in the position 51 2 . The bracket may be fixed to the actuating rod, and the latter moved axially by an hydraulic jack 64 or by rack-and-pinion. Alternatively the actuating rod may be a screw rotated by a fluid pressure or electric motor, and the bracket a nut engaged by it. The actuating rod may be parallel to the aircraft longitudinal axis, or inclined to it. To enable the shock-absorber to pass over centre to the retracted position, it may be extensible, comprising three telescoping tubes, first and second tubes forming the shockabsorber, and the third tube being movable relative to the second on the introduction of fluid between them. This shock-absorber forms the subject of Specification 1,081,018 (see Division B8). As described, three wheels are arranged in tandem, the links mounting them being connected to a common actuating rod.

Abstract: 1,075,421. Sealing containers. VICKERS Ltd. March 5, 1964 [March 8, 1963], No. 9442/63. Heading B8C. An automatically controlled machine (Fig. 1) first vents a closed chamber containing a container C, then introduces an inert gas to the chamber, and finally seals the mouth of the container: this programme is initiated by closing the lid 2 of the chamber. In the configuration shown the sealing means comprise electrically heated jaws 10, 13, the jaw 13 being attached to a piston 22 which is moved by compressed air. The chamber is evacuated by means 53 and an inert gas, e.g. nitrogen, delivered by a pipe 25. The inert gas may be below atmospheric pressure and after the mouth is heat sealed the pressure in the chamber is returned to normal by an air pipe 26. Operation is started whey the lid 2 is closed, causing an arm 5 to push arm 39 against rod 40 and thus join up contacts 41 and 43. The machine stops automatically when the shaft 28 has turned through one complete revolution, at which stage the sealing process will have been completed. In a second configuration two chambers are provided which work alternatively from a combined programming device.

Title: Security enclosures
Inventor: MACPHERSON HUGH
IPC: G06F1/00
Filed: 1993-11-11
Abstract: A security enclosure is formed from layers of flexible material. One layer (11;18) carries a flexible semiconductive line (10,13) arranged to extend over the whole area of the enclosure. Any interruption of the line by unauthorised opening of the enclosure changes the resistance of the line and so can be detected by a monitoring circuit. Further, two layers (17) of semiconductive fibres also cover the whole area of the enclosure and are separated by an insulating layer (16). The length of the fibres is greater than the thickness of the insulating layer (16) so that if the enclosure is pierced fibres from one layer (17) will be forced into contact with fibres from the other layer (17). This will change the combined resistance of the layers and this can also be detected by a monitoring circuit. The two measures can be used separately. <IMAGE>

Title: Levelling arrangement for railway cars
Inventor: WALDA FEDDE
IPC: B65G67/02
Filed: 1986-07-03
Abstract: A railroad freight car having a rotatable loading floor for transferring loads between it and a station platform. The railroad station has two platforms on opposite sides of the rail car. An edge of each platform is provided at each longitudinal end with a sloping beam which angles upwardly from the end of the platform towards its center. The lowest part of the beam, which is at the free end of the platform, is below a set of wheels carried on the chassis of the rail car. The center portion of the platform is at a height above that of these rollers. The rollers are arranged to extend laterally of the rail car and to overlie the beams. As the rail car pulls into the station, the rollers will engage the upwardly sloping part of the beams to thereby raise the chassis in relation to its wheels by virtue of extending the suspension as the car continues in its direction of movement. The chassis is, thus, brought into a suitable level to enable the loading floor to freely rotate to overlie the station platform and, thereby, enable the loading and/or unloading operations to take place.
