Patent GB-2137526-A (GB)
Title: Vial sleeve
Inventor: BAXTER JAMES ALEXANDER
IPC: B01L9/06
Filed: 1983-03-26
Abstract: Automatic sampling facilities (autosamplers) for chromographs and spectrophotometers employ a carousel arrangement for supporting a plurality of different vials each of predetermined size to bring each vial into a sampling position. Where sample quantities are small, narrower vials are used to enable efficient extraction of the samples from the vial. Such narrower vials cannot be supported by the autosampler without considerable adaptation thereto. Instead vial locating and supporting sleeves are used to enable such narrower vials to be accepted by the autosampler.
Patent GB-2140642-A (GB)
Title: Programmable spectrum shaper
Inventor: BARNES GEORGE JOHN PRESTON
IPC: H04M1/24
Filed: 1983-05-25
Abstract: A programmable spectrum shaper, used for example in the generation of test signals for testing telephones, uses a number of filter modules, each including three one-third octave filters (FILTER 1, FILTER 2, FILTER 3), each with its own adjustable attenuator (A1) and buffer amplifier (FBA). There is output bus (ASB) fed by the summed outputs of the FBAs. The analogue input signal is from an input buffer amplifier (IBA) which applies its outputs to all of these filters. A controller module in response to digital input signals selects the filters to be used and their respective attenuations. <IMAGE>

Title: Electron tube with transverse cyclotron interaction
Inventor: CHODOROW MARVIN
IPC: H01J25/00
Filed: 1983-05-31
Abstract: An electron-beam tube for generating high microwave power at high frequencies comprises a fast- wave circuit such as a hollow waveguide with a rear-axial beam (56). The circuit wave has a component of electric field perpendicular to its propagation axis, interacting with motions of the electrons transverse to the axis, in particular with cyclotron rotation in an axial constant magnetic field, as in the well-known "gyrotrons". The fast-wave circuit locks a linearly polarized transverse-electric mode to the orientation of a circuit member such as the ridge (66) rotating helically along the guide. The added periodicity permits beam interaction with a space harmonic of the circuit wave. The { 1 harmonic has a dispersion characteristic which provides beam-wave interaction over a wider frequency range than is possible in prior-art gyrotrons. <IMAGE>

Title: Improvements in ear piercing apparatus
Inventor: GARDNER WILLIAM JAMES
IPC: A44C7/00
Filed: 1983-06-27
Abstract: In an ear piercing gun having a spring-loaded plunger (11), an ear-ring stud (17) is held in a disposable cassette (16) and located in a channel (25) in the cassette. The plunger is released to force the stud through the ear lobe and into engagement with a back clasp (13) located in a disposable insert (15). By using cassettes which are disposable, the ear lobe does not come into contact with the instrument (10) and there is therefore no risk of transfer of infection from the instrument on successive use. <IMAGE>

Title: Two-stroke I.C. engine exhaust ports
Inventor: MACFADZEAN ALEXANDER
IPC: F02B75/02
Filed: 1983-08-02
Abstract: A shutter 12 is arranged to move into an exhaust passage 11 adjacent an exhaust port 10 at or towards the end of the exhaust phase, from the opposite side to the piston 1. Loss of fresh mixture through the exhaust port is thus reduced, since the exhaust port 10 is closed more quickly than it would be by the piston alone. The shutter 12 is reciprocated by a small shaft 14 driven by the main crankshaft 4 at the same speed as the latter but with a phase lag of about a quarter of a revolution. In the position shown in Fig. 1 the piston 1 is being driven downwards and the shutter 12 is fully retracted within its slot 13. About half a revolution later (Fig. 5) the piston 1 is in a similar position, but moving upwards, and the shutter 12 has left the slot 13 and extends about halfway across the exhaust port 10. <IMAGE>

Title: Intruder alarm systems
Inventor: TOUGH FRANK JAMES
IPC: G08B13/183
Filed: 1984-09-14
Abstract: An intruder alarm system comprises a transmitter assembly (10) and a receiver assembly (12) contained in respective elongate housings adapted to be mounted parallel to one another, one each side of an opening, such as a window or door, in the wall of a building. The transmitter assembly has a number of infra-red emitters spaced along the housing and arranged to emit beams of radiation directed towards the receiver, the receiver having a corresponding number of sensors adapted to receive the infra-red radiation. Electronic circuit means connected to the sensors is adapted to provide an output signal if the radiation falling onto any of the sensors is interrupted. The emitted radiation is preferably pulse-code-modulated, and the receiver circuitry includes a correspondingly programmed decoder, arranged to prevent the receiver from responding to spurious radiation from other sources. The electronic circuitry of the transmitter (10) and receiver (12) may be contained within the housings, so that the apparatus is compact and can be easily installed. <IMAGE>
