Title: Process for producing a metal rod for reinforced concrete and a metal rod obtained by said process
IPC: B21B1/16
Filed: 1975-04-04
Abstract: 1508343 Concrete - reinforcing rods L F AURELIO and H J TORRES 4 April 1975 13835/75 Heading E1K [Also in Division B3] A metal rod, Fig. 14 for reinforced concrete has staggered projections 31 for adhesion to the concrete, the projections having the same yield point as the material forming the core of the rod. The rod is made by the following steps. Strips 2, Fig. 1, are cut from metal sheet 1 by cutting discs 3. The strips 2 are wound on drums (6), Fig. 2 (not shown) and unwound passing through lubricating felt discs (17, 18) and through idle shaping rollers (9), (10), Fig. 2a (not shown) to round off the cut edges. The strip is then compacted by a pair of driven rollers (24, 25) Fig. 3 (not shown) to transform the strip into a rod 30 of elliptical cross - section, Fig. 8, which increases its yield point. The rod 30 is then turned by rollers (33-38), Fig. 4 (not shown) so that its major axis 29 becomes vertical. Rod 30 is then passed through driven stud shaping rollers (39, 40), Figs. 5, 5a, 5b (not shown), to form the finished rod 32, Fig. 14, by pressure along the major axis which forces metal away to increase the minor axis to form a rod of circular cross - section with projecting studs 31.

Title: Improvements in or relating to a method of and apparatus for simultaneously polishing both faces of a moving ribbon of glass
IPC: B24B7/24
Filed: 1950-06-02
Abstract: 679,069. Polishing sheet glass. PILKINGTON BROS., Ltd., and GOLIGHTLY, R. H. May 23, 1951 [June 2, 1950], No. 13904/50. Class 60. In apparatus for simultaneously polishing both faces of a moving ribbon of glass 1, Fig. 1, and comprising rotary coaxial tools each carrying a set of polishing discs which overlaps the edges of the ribbon, rouge suspension is fed to the discs of the lower tool by a device comprising a series of parallel tunnels 18, Fig. 3, communicating with a pan 19 to which the suspension is dribbled, the tunnels having their free ends cut obliquely so that each disc extracts rouge from the tunnels as it passes the device. The discs rotate in the direction of the arrow 24 to assist the flow of rouge and to prevent caked rouge from the discs entering the tunnels which are formed by slots cut in a brass plate 17 and provided with covers 25. The slots are rabbeted to receive the covers which are secured by screws or solder. Only one cover extending over all of the slots may be used. The head of suspension in the tank 19 is just large enough to maintain a trickle of rouge through the tunnels and it is kept constant by a drip supply from a pipe 20. To prevent obstruction of the tunnels by dry rouge falling from the upper set of discs the lower wall of each tunnel is cut back as shown at 18a. Where the upper set of discs is rotated in the opposite direction to the lower set, the cover 25b, Fig. 7, is bent down to prevent rouge on the upper discs from being forced into the tunnels. The plate 19 is supported by a bracket 22 from a splash wall 23. Two diametrically disposed devices may be employed with each pair of tools which are driven through worm gearing and flexible couplings from independent motors. Specification 539,540 is referred to.

Title: Improvements relating to resilient mountings for shaft bearings
IPC: F16C27/04
Filed: 1955-05-13
Abstract: 769,816. Supporting and mounting bearings. DAIMLER-BENZ AKT.-GES. May 13, 1955 [May 13, 1954], No. 13906/55. Class 12 (1). A bearing 3 is mounted in an hydraulic device which automatically restores the bearing to a desired central position when a predetermined out-of-centre movement has been exceeded. The bearing 3 is carried in a ring 4 which is mounted in a ring 7 by spring elements 6. Below the bearing, the ring 7 merges into a piston rod 9 carrying a piston 10 disposed in a cylindrical recess in the housing 8. The rod 9 has a central bore 12 into which extends a sleeve 13 which is screwed at its lower end into the housing 8. A slide valve 22 is disposed within the sleeve 13 and is attached to the ring 4 by a rod 24. Vertical upward movement of the bearing 3 beyond a predetermined amount causes slide valve 22 to move upwardly a corresponding amount and permit fluid supplied to an admission port 14 to pass through channel 15<SP>1</SP> in the piston and port 18 to the space above the piston 10. This causes the piston to move downwardly carrying with it the ring 4 and bearing 3. Fluid beneath the piston 10 is exhausted through a port 19 in the sleeve 13. Similarly on downward movement of the bearing the piston 10 is forced upwardly by fluid pressure to restore the bearing to its former position. For securing, at will, the bearing mounting in its central position, the ring 4 is located between spring pressed gripping rings 30. Oil under pressure supplied at 381 acts on pistons 37, 38 in a chamber 36 which force the rings 30 apart to give the bearing radial freedom. The ring 7 may be fitted with two such hydraulic centring devices disposed at right angles.

As shown, element 20 is a daisy wheel (it could be a ball, stick or drum) rotated between stationary printing positions (printing could be on-the-fly). Carriage 1 can be given any of four speeds V1-V4, Figs. 4, 7 (not shown), as determined by processor 610 as a function of the required angular rotation of disc 2. Each speed change is associated with a series of numbers N, Fig. 8 (not shown), which are fed via a memory 615 to preset a counter 630 which is counted down to zero to produce a train of stepping pulses 21A for a stepping motor. To shift the carriage one column 6 stepping pulses and hence 6 numbers are required, each accompanied by a direction-indicating bit 21B; they are followed by an "all zeros" number which is detected at 616 and used to enable gates 671A-671D receiving a signal 610V1, 610V2, 610V3 or 610V4 indicating the carrier speed at the print position: an appropriate one of monostables 672A-672D is triggered to provide a variable delay before firing of the hammer drive circuitry 660. Rotation of disc 2 is controlled by means of a step motor 22 and circuitry similar to that described above. In alternative embodiments, the carrier speed may assume any values between two limits, and provision for proportional character spacing may be made.
