Title: Improvements in butt seam joints for sheet material and the like
IPC: A44B19/14
Filed: 1956-10-02
Abstract: 805,147. Sliding clasp fasteners. HUBNER, F. K. Oct. 2, 1956 [Oct. 6, 1955], No. 30040/56. Class 44 A sliding-clasp fastener for joining two pieces of sheet metal comprises flat locking members 3 arranged on pivots 4 secured to the margins of the sheet metal, each locking member 3 having a projection 5 extending radially from the pivot and formed with two hooks 6 which engage adjacent hooks on adjoining locking members, and each pivot 4 having a head part 12 which extends beyond its associated locking member and guides a slider 14 which operates the fastener by engaging upstanding driver fingers 7 formed on each locking member and causing them to move in grooves 18 in the slider and thereby rotate the locking members through 90 degrees into engagement with one another; each locking member is resiliently retained in the disengaged position by a spring holding means attached thereto. As described, the pivots 4 are riveted to strips 1 which are in turn riveted to the sheet metal. The strips 1 are zigzag shaped so as to follow a curved join. Each pivot head 12 has oblique under surfaces; and a leaf spring is provided which embraces and rotates with the upstanding driver finger 7 of each locking member and is adapted to seat against these under surfaces in the disengaged position of the fastener which is thus resiliently held in this position.

Title: Race rings for rolling bearings and to rolling bearings having  such race rings
IPC: F16C33/60
Filed: 1970-06-22
Abstract: 1357526 Bearings SKF (UK) Ltd 1 Sept 1971 [22 June 1970] 30218/70 Heading F2A A method of making a race ring for a rolling bearing comprises forming at least two ring elements, at least one of which has a concave surface 13 tapering from a maximum diameter at its junction with a cylindrical outer surface 12 to a minimum diameter at its junction with end face (14), Figs. 1-3 (not shown), to provide part of a raceway, and another of which has a concave surface 13 to provide part of the same raceway surface, assembling the two elements with their two concave surfaces forming a continuous raceway surface 11, electron beam welding the ring elements together, and finish-grinding the raceway surface 11. The ring elements may be formed, for example, by cold forming or sintering. The inner ring element of Fig. 1 is paired with another of the same dimensions with their bores co-axial and end faces (14) opposite each other. They are then welded together starting from the raceway surface and then subjected to any necessary heat treatment, e.g. case-hardening, followed by a finish-grinding to the required dimensional accuracy. Alternative embodiments feature a bevel (17) or recess (18) in the end surface (14) so as to lessen the risk of weld metal 15 projecting into the bore 11, and thus precluding much grinding. Outer race rings may be formed, Figs. 6, 7 (not shown), so as to accommodate rows of balls (21), (22) rolling on raceway (23). The inner race ring of this embodiment comprises three elements (25), (26) forming a raceway for each row of balls. A further modification includes the assembling of sintered ring elements followed by electron beam welding to provide not only a weld joint but also a melting of the raceway surface to provide on cooling a homogeneous bearing surface.

Abstract: 899,621. Radar; duplex radio signalling. ELECTRIC & MUSICAL INDUSTRIES Ltd. Oct. 1, 1958 [Oct. 1, 1957], No. 30677/57. Classes 40(5) and 40(7). Means are provided in a radar for protecting the receiver against the transmitted signal and for preventing the reception of echoes from rain by utilization of the effect that a normal target reflects a circular polarised wave without change in the absolute direction of polarisation whereas reflection by rain reverses the absolute direction of polarisation. As shown the transmitter 1 and receiver 5 are coupled by rectangular waveguides 2 and 6 to a known type of crossed polarisation duplexer 3 which permits transmission of vertical linear polarised waves from the transmitter 1 to a circular waveguide 7 coupled to the aerial 10 and permits transmission only of horizontal linear polarised waves to the receiver 5. The aerial waveguide 7 includes (1) a rotator 8 which rotates the plane of polarisation through 45 degrees in the same sense irrespective of the direction of transmission and (2) a circular polariser 9 which produces clockwise circular polarisation of the transmitted signal so that clockwise circular polarised echoes from a normal target are converted by the polariser 9 into signals linearly polarised at 45 degrees to the vertical which are converted by the rotator 8 into horizontal polarised signals which can pass through the duplexer 3 into the receiver 5 whereas anticlockwise circular polarised echoes from rain are converted by the polariser 9 into signals linearly polarised at 135 degrees to the vertical which are converted by the rotator 8 into vertical polarised signals which cannot pass to the receiver 5. The rotator 8 may comprise a longitudinal magnetic field and a gas plasma or ferrite rod, e.g. a Faraday rotator, and the polariser 9 may comprise a vertical conducting vane acting as a phase plate.
