Abstract: 591,730. Resilient mountings. DUNLOP RUBBER CO., Ltd., GRAY, T. E. H., and GURNEY, W. A. May 11, 1945, No. 11832. [Class 108 (iii)] An anti-vibration mounting of the co-axial bush type comprises inner and outer bushes 7, 8 connected by a plurality of radial arms of rubber or like material bonded to and inclined to the axis of the bushes and symmetrically arranged in sets around the axis, the arms of each set being staggered and oppositely inclined relatively to the arms of the adjacent set. As shown, the bushes 7, 8 are connected together by four sets 9A, 9B, 9C. 9D of rubber arms of rectangular shape and constant or variable cross-section, the arms being so spaced as to assume a spiral formation. As the arms do not overlap when viewed in an axial direction, the mounting may be produced in a single operation by shaping a rubber &c. composition between mould sections which are brought together axially between the bushes to form arms of the required shape and inclination, and then heating the assembly to vulcanise the composition and bond the arms to the bushes simultaneously. In another construction, the bushes are connected together by two sets of inter-crossing arms.

Title: Arrangement for braking of dispatch carriers in pneumatic tube conveying systems
IPC: B65G51/20
Filed: 1966-03-18
Abstract: 1,122,856. Pneumatic dispatch apparatus. INTERNATIONAL STANDARD ELECTRIC CORP. 18 March, 1966 [22 March, 1965], No. 11977/66. Heading B8A. A section of a pneumatic tube conveying system is adapted to brake the carriers pneumatically and is provided with pressure relieving means causing air compressed in the space ahead of a moving carrier to be transferred to the rear of the carrier to prevent reversal of the carrier's motion. As shown, the braking section AC is closable by flaps 2, 3 and is provided with air-receiving vessels 4, 6 connected to the section by valves 5 consisting of flaps with choke holes in them. As a carrier moves through the section, most of the air compressed ahead of the carrier is forced into the vessels 4, 6, the remainder of the air being forced through chokes 9, 10 in by-pass tubes 7, 8. The arrangement is such that the slow leakage of air from the vessels 4, 6, after the passage of the carrier and through the chokes 9, 10 prevents any tendency for the carrier to be reversed. In a second embodiment (not shown), air pressure ahead of a carrier is leaked to the rear of the carrier by having a widening of the bore of the tube 1 along the braking section.

[Also in Division H1] In a microwave oven power is fed from a magnetron to the oven cavity via a waveguide which incorporates a Faraday rotator whereby reflected waves from the cavity are prevented from reaching the magnetron. In one feeding arrangement, Fig. 1, the waves from the magnetron are polarized as indicated at the mouth of rectangular section 2, circular section 1 encloses a ferrite rod 4 and is surrounded by a permanent magnet or a coil 5 and the polarization of the waves is rotated through 45 degrees. In an embodiment to prevent heating of the ferrite rod by oscillation in section 1 an additional and closed waveguide 8. Fig. 2, is coupled to section 1 by a slot 9, the waveguide 8 containing a wave absorber. The distance from the L.H. end of section 1 to the centre of slot 9 is made an integral number of half-wavelengths. In an alternative embodiment a wave-absorbing sheet of metal covered with a layer of graphite is placed on the centreline on either side of the ferrite rod, Fig. 3. The current to the magnetizing coil comprises an adjustable portion and at least part of the anode current of the magnetron; the same heating time for the same kind of food, independent of main voltage variation, is thereby achieved.
