Title: Railway wagon bogie friction damper pads - have rubber spring supports on bogie arranged in V-formation
Inventor: TANK JOACHIM
IPC: B61F5/14
Filed: 1976-02-24
Abstract: Each friction damper pad (10) is supported for engagement with a railway wagon body by two rubber springs (12) comprising laminated chevron plates extending parallel to substantially vertical support surfaces (13, 14), so that vertical movement places the springs (12) in shear and longitudinal movement places the springs (12) in compression. The unloaded angle (A) is 120 deg. and the static load angle (A') is 160 deg.; the angle (B) is less than 10 deg.. The chevron angle is about 150 deg.. The centre plates (17.1) of each spring (12) are connected rigidly by longitudinal members to form a frame, the inner parts (12.1) being fixed to the central block (15) and the outer parts (12.2) to the centre plates (17.1) of the frame. A rib (18) on the housing (11) co-operates with a groove (19) in the central block (15) to limit vertical and longitudinal displacement. The lateral walls of the housing (11) limit the transverse displacement of the springs (12).

Title: Continuous arc welding metal strip onto tube - to make a helical fin very suitable for heat exchanger tubes
IPC: B23K9/032
Filed: 1976-03-03
Abstract: A helical fin is continuously welded onto a tube while the latter is rotated on a horizontal axis so then a metal strip forming the fin is carried on edge round the tube and welded by an electric arc at the point of contact. Welding is undertaken on the upper quarter of the cylindrical surface of the tube as it travels towards a vertical plane intersected by the axis of the tube. The arc is pref. created at a distance of 70-50 degrees from the vertical plane; and the pref. machine is of a conventional type in which the tube is rotated on a horizontal axis. Guide rollers feed the metal strip upwards so it is drawn round the tube and welded as a helix in the manner defined above. Used in mfg. industrial boilers, and esp. for mfg. heat exchanger tubes. The rotation of the tube and the feeding of the metal strip are designed for "descending" welding, i.e. the weld pool tends to flow downwards; the result is that the welding speed can be increased without breakdown of the arc, but high quality welds are still obtd.

Title: Integrated optics deflector using electromechanical transducer - is in form of piezoelectric layer deposited on substrate, and optical waveguide
Inventor: SANDBANK CARL PETER
IPC: G02B6/35
Filed: 1976-03-18
Abstract: The integrated optics deflector device comprises an optical waveguide (10) formed in or on a substrate which has an area covered by an electromechanical transducer (13). This has a series of interdigital electrodes (14) which extend transversally on the waveguide (10). The individual electrodes are placed in the same direction as the waveguide. The transducer is separated from the waveguide by a dielectric film (12) whose refractive index is less than that of the waveguide. The transducer enables the mechanical stresses produced to be coupled into the waveguide where they produce a phase grating.

Title: Diaphragm-type distribution pump - has lever moving diaphragm clamped by flange between upper and lower body sections
IPC: F04B53/10
Filed: 1976-07-09
Abstract: The diaphragm-type distribution pump has top and bottom sections sealed to each other to form the body, the diaphragm (20) being clamped between them by means of its non-perforated flange, so as to form a closed chamber (22) between it and the top section. The volume of this chamber is varied by means of an actuating lever (26) bearing against the underside of the diaphragm and pivoting in the body. The lower part of the latter has an inlet port (36) leading from the fluid reservoir (34) to the joint face with the toip section, which has a hollowed-out-portion opposite it extending from the flange edge to the pump chamber. Thus the flange acts at this point as a flap valve opening upwards. There is also a delivery port in the upper section from the pump chamber to the upper side of the flange at another point, above a hollowed-out portion in the lower section allowing the flange to open downwards and the fluid to be discharged to atmosphere.

Title: Current limiting switch with electrodynamic drive - has two part electric energy store, one part used for normal operation and both for short circuits
IPC: H01H3/22
Filed: 1977-01-07
Abstract: The electrodynamic drive is intended for rapid breaking of the switch, and the electric energy store supplies the electrodynamic drive. The store consists of two parts, one part being sufficient for the switching-off under normal operating conditions. The electrodynamic drive can be selectively connected to one store part for breaking in normal operation, while being connectable to both parts at short circuit condition. The electrodynamic drive contains a breaking coil with a conductive disc in front of it. Thus a current pulse in the coil actuates a strong repulsion of the disc by the Thomson effect. The energy store consists of a capacitor-bank. A second energy store and electrodynamic drive of identical design may be provided, which controls the making of the switch during discharge of the second store through the second coil.

Title: Lifting machine load limiter - produces memory signal switching off machine control circuit when load remains above reference level for predetermined period
IPC: B66B1/48
Filed: 1977-04-27
Abstract: A detector generates a signal whose level varies according to the lift force. An electrical control circuit includes an comparator which compares the detector signal level with a reference level which is proportional to the effort required for a given load. The comparator produces an output signal having a first state when the detector signal is greater than the reference, and having a second state when the signal is equal to or less than the reference. A time counter responds to the first state and generates a pulse when the first state persists for a given time. A memory responds to the pulse, so as to produce a control signal. A switch having a contact in the control circuit of the lifting machine responds to the control signal and interrupts the control circuit.
