Title: Improvements in or relating to brake discs for rail vehicle wheels
Inventor: MOLLER ERNST
IPC: F16D65/12
Filed: 1966-03-22
Abstract: 1,080,640. Disc brakes. KNORR-BREMSE G.m.b.H. March 22, 1966, No. 12685/66. Heading F2E. An annular disc 13, for engagement by a pad or pads of a disc brake assembly (not shown) for a rail vehicle, is of cast iron and has cast into its inner periphery spokes 11 which are integral with and extend substantially tangentially from an annular support body 7 of cast steel, which is welded or glued to a hub portion 1 of a wheel of the rail vehicle at one or both sides of its central web 2. The hub portion may be cylindrical (Fig. 2, not shown) or conical (Fig. 3, not shown). A relatively high resistance to axial deflection of the disc under the pressure of the brake-applying means on the disc 13 is achieved by making the spokes of rectangular section with the widest dimension arranged in the axial direction, while elastic deformation of the spokes can occur in the radial direction should the heat generated by the pads cause radial movement of the disc 13. Reference has been directed by the Comptroller to Specification 1,032,923.

IPC: B41G1/00
Filed: 1929-04-25
Abstract: 310,431. Eckert, C. April 25, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Embossing-machines. - Mechanism for feeding a number of metal foil strips 18 in an embossing-press 1 comprises chains, belts, or the like 19 driving the feed rollers 17 and connected at their ends to an oscillating member 23. The chains 19 drive the rollers 17 through ratchet-and-pawl arrangements 20 and at their free ends are connected to springs 27 or weighted so as to be drawn back as the segmental member 23 makes its return stroke. The chains are adjustably connected in slots on the member 23 by spring-pressed pins 25, the position of adjustment determining the amount of feed of each strip as the chains hang freely between the rollers 17 and the segment and have to be pulled taut before beginning to act on the feed rollers. The feeding mechanism is attached to bars 3 fixed to the upper pressure member by chains 13 or similar flexible devices or by hook bolts and extended at the front of the press to carry pillars 4 to which the roll-carrying frame 6 is pivoted at 9. Stops 11 limit the downward movement of the frame 6 which can be swung upwards if it is not desired to use the foil. The member 23 is operated from the press by connecting the operating lever 29 thereto by a chain 31 and projecting arms 30, 32, so that as pressure is applied to the press the chain is slackened as shown, and when the press is opened the chain is pulled taut and the foil fed forward the required amounts. In a modified mechanism, Fig. 8, for operating the feed from the hand-lever 33 of the press, a chain 45 connects the member 23 to a lever 44 fixed to a shaft 34 carrying a second lever 35 pivoted to a sleeve 36 adjustable on a lever 37. At one end of the lever 37 is a balance weight 47 and at the other end is a grooved block 42 adapted to receive the end of the lever 33 as it is moved upward, so that the foil is fed forward as the press is opened. A stop 39 on the sleeve 36 holds the lever 37 in the position shown, but the lever 37 can be swung upward into a vertical position when it is desired to render the feed mechanism inoperative. The block 42 may be replaced by a roller.

Patent GB-348857-A (GB)
Title: Process and apparatus for the manufacture of glass tubes and rods
IPC: C03B17/04
Filed: 1930-04-28
Abstract: 348,857. Making glass tubes and rods. JORGENSEN, J. R. C., 26, Farring- don Street, London.-(Assignee of Bosc, L. ; Place Chapu, Melun, Seine-et-Marne, France.) April 28, 1930, No. 13069. Convention date, Nov. 6, 1929. [Class 56]. A process for making glass tubes or rods consists in causing molten glass to overflow a weir and in feeding a sufficient quantity of glass to the zone adjacent to the weir to keep the overflow constant. The glass flows from a tank furnace 1 through a conduit 2 into a circular container 4, the rate of flow being controlled by an adjustable gate 3. The container has a central aperture 13 formed in a conical wall 5 rising from the bottom. The wall serves as a weir over which the glass flows to form a tube or rod X, the tube being drawn away and cut up by any suitable mechanism. The aperture 13 may be of circular, polygonal, or other cross section according to the shape desired in the finished tubing. The container has an annular cover 4<2> with a central opening coaxial with the aperture 13, and the inner wall 4<3> of the cover dips into the glass in the container. The aperture 13 is thus surrounded by a zone 7 in which the glass is undisturbed by the glass flowing into the container through the conduit 2. The container 4 is seated above an opening in the floor of a chamber 6 which is heated by any suitable means. The cover 10 of the chamber is provided with a depending wall 9 which rests on the cover 42 of the container. The space above the aperture 13 is thus shielded from the heat in the chamber 6, and an adjustable opening 11 above the aperture enables the temperature and viscosity of the glass in the zone 7 to be regulated.
