Patent GB-2077845-A (GB)
Title: Plastics Drive Fasteners
IPC: F16B19/00
Filed: 1981-06-15
Abstract: A fastener 10 has a shank 14 presenting four surfaces 16. An opposed pair of the surfaces 16 have respective rows of radially extending wings 18 and the other two surfaces 16 have respective rows of angled wings 30. Although the wings 18 flex about straight lines at their junctures with the surfaces 16, the wings 30 flex about straight lines 36 spaced radially from the surfaces 16 because of thickened sections 34. This substantially increases the force required for removal of the fastener from an apertured workpiece as compared to the force required for introducing the fastener. <IMAGE>

Patent GB-2082039-A (GB)
Title: Treating plant materials with ammonia
IPC: A23K50/15
Filed: 1981-07-15
Abstract: For the treatment of chopped straw and similar plant materials with ammonia, the ammonia is fed from a pressurised container, and the ammonia, before being conveyed to the location of treatment, is relieved of pressure to provide for a particularly effective mixing of the chopped straw and the ammonia. To obtain such a pressure relief in a simple manner, the ammonia is fed to a chamber (1) of circular cross-section, and the ammonia is fed tangentially through inlet opening (6) into the chamber so as to provide for an effective separation between vapour and pressure relieved liquid ammonia, which is discharged at the bottom (3) of the chamber and conveyed to the location of treatment, while the ammonia vapour is discharged through a discharge opening (11) communicating with a pipe (2) which is centrally disposed in the chamber and terminates shortly below the top (4) of the chamber, the ammonia vapour being either discharged or being passed to a location of treatment for the material. Water may be fed to the chamber through opening (5). <IMAGE>

Patent GB-2081424-A (GB)
Title: Fluid control valve
IPC: F16K41/02
Filed: 1981-07-31
Abstract: An ajustable secondary seal 25 is provided between a valve spindle and a valve body 10. The valve body 10 has a flanged inlet fitting 11 and flanged outlet fitting 12, and provides a main valve seat 14 adapted to be closed by a corresponding seating 15 on a valve plunger 16. The valve spindle is divided into two portions, an upper spindle 17 and a lower spindle 18 which forms part of the valve plunger 16. On the upper spindle is a flange 19 corresponding to a similar flange on the lower spindle 18. The upper spindle includes a downwardly projecting stub shaft 21 which has flats 22 on its sides adapted to mate with corresponding flat surfaces 23 formed in a bore 24 in the upper end of the lower spindle 18. The secondary seal 25 which may be an O ring, a washer, or ring washer, is arranged to be trapped between the flanges 19 and 20. To exert pressure on the O ring 25 a screw or bolt 26 is provided which passes through a bore in the upper spindle 17 and engages a threaded bore in the lower spindle 18. By tightening up the screw or bolt 26, the O ring seal 25 will be compressed between flanges 19 and 20 and the tightness of the screw or bolt 26 will determine the pressure exerted on the O ring seal 25 and hence the sealing effect of the secondary seal. <IMAGE>

Title: Doppler lidar
Inventor: DUVENT JEAN-LOUIS
IPC: G01S17/10
Filed: 1982-10-15
Abstract: In a doppler lidar, light of frequency f1 is emitted from both ends (3, 4) of a laser (1). The transmitted beam (25) is periodically translated and frequency shifted by an acousto-optical device (7, 8, 9, 10) so as to produce a sequence of pulses of frequency fD = f1 a long beam (27, 29). The received beam (30, 31) of frequency f2 is mixed with the heterodyne beam (26,32) by half-silvered mirror (19). The composite beam falls on a detector (20) and a signal of frequency f1-f2 passes through a filter (24) to processing circuitry (23) to yield range and/or speed information. In order to prevent backscattered light of frequency fD passing through the laser (1) and mixing with the heterodyne beam (26,32) the frequency fD must not equal kc DIVIDED 2L, and preferably equals (2k+1)c DIVIDED 4L, where L is the length of the resonant cavity (2) of the laser (1), k is an integer, and c is the speed of light. <IMAGE>

Patent GB-2127521-A (GB)
Title: Vibratory apparatus
Inventor: MUSSCHOOT ALBERT
IPC: B65G27/32
Filed: 1983-07-12
Abstract: A system for varying the vibration generating force of a rotating eccentric weight by providing a second weight movable from a position on one side of the axis of rotation of the eccentric weight to a second position on the opposite side of the axis of rotation, the movement being linear and radially across said axis of rotation. In addition, a spring may be employed to move the movable weight toward the second position initially, in compression, and later to resist additional movement in said direction, in tension, so as to provide basically a linear system for varying the vibrational force. Fluid pressure may be applied to the movable weight which pressure will combine with the tension in the spring to move the movable weight against centrifugal force and toward the axis of rotation of the wheel. Once the center of gravity of the weight passes the axis of rotation, further fluid pressure on the movable weight will act against the compression of the spring and will combine with the centrifugal force to move the movable weight radially outward from the axis of rotation. <IMAGE>
