Patent GB-2161932-A (GB)
Title: Acoustic distance sensing system
Inventor: HANKS PAUL
IPC: G01S15/14
Filed: 1985-07-15
Abstract: In apparatus for sensing distances in air by timing delay from transmission of an ultrasound or sonic pulse to the return of its echo variable amplification is applied to the received echo signal. The amplification is determined by digital data held in a memory (38) addressed by a counter (40,41) which is incremented progressively after transmission of the pulse. The data at the addressed location determines amplification by a digital to analogue converter (34). The change with time follows an experimentally determined curve to compensate for the attenuation in air of the pulse and its echo so that weaker spurious echoes are discriminated against. <IMAGE>

Patent GB-2218773-A (GB)
Title: Lining sewers
Inventor: ZUEST HARRY
IPC: F16L55/1645
Filed: 1989-05-10
Abstract: In the process disclosed, an intermediate layer (2) is first applied in the pipe (1) to be lined and then a mechanically and chemically stable layer (3) to be sealed is applied to the insulating intermediate layer. The intermediate layer provides a thermally and chemically suitable base for the sealing resin system, on which the desired coating can be applied, despite the presence of dirt and moisture in the drainpipe, so as to ensure curing in conformity with the specifications and a service life corresponding to the material used. In another preferred form, a resin layer is applied directly to the inner surface of the pipe to be lined. To eliminate moisture, the component of the resin system which reacts with water is sprayed onto the inner surface of the pipe, thereby setting with the water. The resin mixture is then applied by centrifuging. If desired, a final layer consisting of a resin system of greater hardness and greater mechanical strength can be applied to the resin layer formed. In this case, the lower, first resin layer provides the proper medium for a more sensitive resin system, such as an epoxide resin.
