IPC: E04H17/16
Filed: 1989-04-15
Abstract: A fence assembly comprises at least one mesh panel 1, a hollow post 2 and at least one retaining bar 3. The post 2 defines a series of parallel transverse slots 13 and the mesh panel 1 is made up of strands 5 forming along at least one edge of the panel a series of parallel hooks or loops 8 which can each be inserted into one of the slots in the post 2.

Patent GB-2220362-A (GB)
Title: Respirator
Inventor: KOLBE ERNST-GUENTHER
IPC: A62B7/10
Filed: 1989-06-26
Abstract: A respirator for overpressure operation comprising a pressure gas source (1) supplying respiratory gas and a respirator bag (6) which is compressed in the inhalation phase, the said compression being reduced in order to support respiration in the exhalation phase by means of a switching device (3) which recognises the respiration phase, is improved with a view to obtaining a simplified, purely pneumatic-mechanical construction. According to the invention, this is attained in that there is provided a pneumatic control valve (3) which can be switched between the inhalation phase and the exhalation phase, which is directly controlled by the pressure difference between the exhalation pressure and the pressure in the respirator bag (6), which during the inhalation phase connects the pressure gas source (1) to the respirator bag (6), and which during the exhalation phase actuates a pneumatic adjustment device (4) in such a manner that the mechanical compression of the respirator bag (6) by spring (13) is reduced by exposing the connection to cam (15) as an effect of the dynamic pressure produced by the pressure gas source (1) acting through coupling element (30) one gear (38) on the pivot axis of the movable wall (16) of the bag (6). …<IMAGE>…

Patent GB-2244876-A (GB)
Title: A.C. Power controller with short circuit and overload protection
Inventor: IONESCU ADRIAN F
IPC: H02H3/02
Filed: 1990-06-06
Abstract: An A.C. solid state power controller for controlling the current through a load 250 from an alternating current source 12, includes a diode bridge rectifier 70-100 with its direct current output connected to a solid state switch 130, such as a MOSFET or a bipolar transistor, that is controlled by control signals synchronized to the A.C. source. The control signals are provided, such as from an optocoupler 40, to control the solid state switch and the load current. Overload, short circuit, and low A.C. line voltage conditions are sensed by protection circuit 170 which signal the optocoupler to turn off the solid state switch and, thus, the load current. A fast turn off time, in the range of a few microseconds, is achieved which, together with the rectifier and solid state switch configuration, provides a power controller which is resistant to short circuit and overload destruction present in conventional A.C. solid state circuit breakers and power control devices. After detecting an overcurrent the protection circuit 170, which is described in detail (Fig 6) resets the current and if overload continues the solid state switch 130 is turned off. The number of repeated attempts to restore current is determined by a counter (814, Fig 6). <IMAGE>
