Title: Using dry transfer sheets
Inventor: SHEPHERD JOHN VICTOR
IPC: B44C1/17
Filed: 1983-06-08
Abstract: By transferring dry transfer letters from a dry transfer lettering sheet onto a receptor which yields under the applied pressure, e.g. a sheet of paper for example mounted on a soft material, such as a foam plastics pad, or mounted on a lightly spring loaded platform, they are adhered to the receptor evenly but not too firmly. A legend built upon such a receptor can be removed as a whole using an adhesive transfer tape and then repositioned e.g. to enable it to be laid down where desired on a desired final surface, with the transfer tape acting as the carrier sheet of a simulated "dry transfer material" bearing the transferable legend. The degree of yield of the receptor preferably corresponds to a softness factor (as defined by a test described in the specification) of 0.15 to 9.0. <IMAGE>

Title: Inclined screen
Inventor: NADEN DAVID
IPC: B03B7/00
Filed: 1983-06-24
Abstract: An inclined screen separator 12, 14 is used to separate adsorbent particles from a slurry, which is being treated in vessel 1 by countercurrent contact with the adsorbent particles, so that the separated particles may be conveyed from one chamber 3 to the next chamber 4. The chambers are separated by a sieve 5 which allows the slurry to pass through but not the adsorbent. The slurry may be finely divided ore containing Cu, Au or U which is picked up by the adsorbent, the adsorbent loaded with the metal being discharged at 22 and depleted ore at 8. The separator comprises a level detector 23 which acts in conjunction with a timer 20 to control the flow of adsorbent-slurry mixture up line 11 and/or the return of separated slurry and adsorbent through lines 17 and 19, intermittently or continuously. <IMAGE>

Title: Auditory subliminal message system and method
Inventor: LUNDY RENE RICHARD
IPC: H03G3/32
Filed: 1983-07-05
Abstract: Ambient audio signals from the customer shopping area within a store are sensed at 30 and fed to a control circuit 12 which adjusts the amplitude of an auditory subliminal anti-shoplifting message from 48 to increase with increasing amplitudes of sensed audio signals and decrease with decreasing amplitudes of sensed audio signals. This amplitude controlled subliminal message may be mixed with background music and transmitted to the shopping area. To reduce distortion of the subliminal message, its amplitude is controlled to increase at a first rate slower than the rate of increase of the amplitude of ambient audio signals from the area. Also, the amplitude of the subliminal message is controlled to decrease at a second rate faster than the first rate with decreasing ambient audio signal amplitudes to minimize the possibility of the subliminal message becoming supraliminal upon rapid declines in ambient audio signal amplitudes in the area. A masking signal, which may be combined with the subliminal message, is provided with an amplitude which is also controlled in response to the amplitude of sensed ambient audio signals. <IMAGE>

Title: Radio communications systems
Inventor: O'NEILL SIMON PHILIP
IPC: H03L7/185
Filed: 1984-02-23
Abstract: In a radio communication system having two or more fixed transmitter stations transmitting signals on nominally the same carrier frequency to mobile receivers which may be in a position to receive signals from both or all said transmitters, the actual carrier frequencies are arranged to be offset from one another by one, two or three Hertz in order to avoid stationary "dead" zones. Each transmitter includes a phase-locked loop for locking the output oscillator 1 to a reference frequency (Fref) and a selected frequency offset is produced by a single-sideband mixer arrangement 6-10 comprising a divide-by-four circuit 6 producing quadrature signals at one-quarter of the carrier frequency. These are mixed 7, 8 with quadrature signals at 1 DIVIDED 4, 1 DIVIDED 2 or 3 DIVIDED 4 Hz from generator 9 and the resultants summed 10. Generator 9 may be a ROM providing successive amplitude values. <IMAGE>

Title: A method of reducing pressures on tunnelling shields and tunnel linings in weak rock
Inventor: HOLESTOL KJELL
IPC: E21D11/08
Filed: 1985-12-19
Abstract: A method of reducing the pressures from weak rock on shields 11 used for tunnel driving, as well as reducing pressures on tunnel linings, by filling the void between the shield 11 and the surrounding rock 3 with an expandable, hardenable and deformable material, said void being filled by injection with the material. The deformation and strength properties of the material will allow controlled deformation of the rock towards the shield 11 and the tunnel support 2 such that the applied rock pressures are reduced. The invention reduces the danger of immobilisation of the shield because of being squeezed by the deforming rock and will allow tunnel supports to be designed for substantially reduced rock pressures. <IMAGE>

Patent GB-2171062-A (GB)
Title: Floating breakwater
Inventor: MACKAY REAY
IPC: E02B3/06
Filed: 1986-02-05
Abstract: A floating breakwater comprises a wall structure (4) preferably made from steel plating and provided with edge buoyancy chambers (8,10) to enable the structure to float in water. The wall structure (4) is substantially submerged and is set at an inclined angle e.g. 30 DEG to the calm water surface (K) so as to present an inclined shelving surface to oncoming waves whereby the waves break on the shelving surface to attenuate their energy. Submersion and incline of the structure 4 can be obtained simply by a downward pull on the structures leading edge (14) by means of mooring chains (22), but an alternative or additional arrangement utilises a variable buoyancy effect over the length (L) of the wall structure. The invention provides a breakwater which is relatively straightforward and economic to manufacture, but which will be effective in use. <IMAGE>
