Patent GB-2100950-A (GB)
Title: Crystal filter
Inventor: TRUELOVE ANTONY HARRY
IPC: H03H9/56
Filed: 1981-06-23
Abstract: A monolithic band-pass crystal filter, for use, for example, as a radio channel filter, uses a single plate of quartz (1) operating in the thickness shear mode. This gives over 90 dB attenuation in the stop band. To prevent unwanted acoustic couplings between the resonators of the various filter sections due to mechanical acoustic vibrations in the quartz, one or more acoustic barriers are used. Such a barrier consists of a metal-loaded epoxy paste, which heavily attenuates the interfering modes of vibration, and can have grooves and/or holes under the paste to reinforce the attenuation. Some of the resonators on the same side of the barrier, i.e. in the same region of the quartz, are coupled acoustically by an evanescent wave.   The or each acoustic barrier may be so oriented as to absorb acoustic waves propagating in the X direction of the quartz while the resonators of the filter sections are oriented in the rotated Z direction of the quartz. To further improve the characteristics, the geometries of the resonator section and/or of the regions on the quartz plate can be varied. <IMAGE>

Filed: 1981-07-09
Abstract: In order to improve the quality of an alloy e.g. Zn/Al coating formed by immersion in a liquid bath of the alloy, the metal object to be coated is first immersed in a liquid bath of zinc. There is thus no need for special pretreatment other than that conventionally provided before galvanizing. The Zn/Al bath may be maintained at approx. 600 DEG C and may further include Mg and/or Si. Forced drying may be provided after each bath. <IMAGE>
Patent GB-2100386-A (GB)
Title: Plugging tubes
IPC: B21D39/04
Filed: 1982-02-26
Abstract: The invention relates to a plugging assembly for tubes, particularly for closing heat exchanger tubes in the event of leaks developing which could result in separate fluids becoming unintentionally mixed. According to the invention, such plugging apparatus comprises a plug member (14) for insertion into the end of a tube (12), a force-transmitting sleeve (20) within the member (14), and an explosive element (22) within the sleeve (20). A plurality of projections (24) extend from the outer surface of the member (14) to an extent such that in use they will be proximate the inner surface of a tube (12) in which the plug member is inserted. Upon detonation of the explosive element (22), the plug member (14) is expanded radially outwardly to drive the projections (24) against the tube (12). <IMAGE>
Patent GB-2096979-A (GB)
Title: Screw-threaded metal caps
IPC: B65D51/16
Filed: 1982-03-02
Abstract: In a combination of a screw- threaded metal closure cap 1 with a container 10 having an externally screw-threaded neck, of the type in which the closure thread 3 is formed by a thread rolling operation in a blank in situ on the container, one or more interruptions 4 are made in the closure thread to provide a pressure leakage path, through which gas can blow off in the interval between unsealing the container and the release of the closure from the container thread. Complementary notches may be formed in the container thread. The interruptions in the closure thread are conveniently provided by forming the thread by means of a thread roller having one or more notches in its periphery. <IMAGE>
Patent GB-2093782-A (GB)
Title: Road or rail vehicle buffer stop
IPC: B61G5/04
Filed: 1982-03-02
Abstract: The buffer consists of elongated, compact sliding blocks (1) which are rigidly connected by transverse connection blocks (2) and tie-bars (3). The buffer is non-fixedly placed on the roadway or on a bedding on a rail track. The bases of the sliding blocks are bevelled opposite the vehicle approach side to avoid the edges biting into the ground as the blocks slide on vehicle impact. In order to equalise the impact levels a crossbar (8) may be disposed flush at the approach side and this crossbar (8) is reinforced by reinforcement ribs (7). In order to increase the braking force, ramp elements (4) may be fitted at the approach side and/or at the bases of the sliding blocks (1) ribs, grooves or toothed structures may be fitted. The buffer has the advantage of reducing expenditure for the repair of vehicles, buffer and track systems, in reducing the assembly and disassembly expenses when the buffer is used temporarily and in improving work safety. It also requires a relatively small amount of space and absorbs large approach forces. <IMAGE>
