Patent GB-2124136-A (GB)
Title: Technique for double layer moulding of articles
Inventor: LACE DAVID
IPC: B29C41/22
Filed: 1983-07-12
Abstract: A method of forming an article which is to have an inner layer or filling of a second material disposed on the inside surface of a hollow moulding made of a first material, in which there is introduced into the mould, in addition to the material which is to form the first outer layer when the mould is heated and rotated, a second material contained within an envelope of thermosoftening material capable of melting sufficiently to rupture as a result of the heat applied, whereby the second material is then released to form the second layer or filling on the inside surface of the first layer. In a preferred embodiment a toroidal lifebelt is made by locating polyethylene powder and at least one meltable envelope containing sand into a mould and rotating and heating the mould to cause the polyethylene powder to melt and form an outer layer and the envelope(s) to melt and allow the sand to form an inner layer.

Title: A jacking device
Inventor: REDDAWAY ANTHONY LEWIS
IPC: B66F19/00
Filed: 1983-08-16
Abstract: The jacking device comprises two blocks (10, 11) arranged one above another and a wedge (12) interposed between the blocks. The major outer surfaces (16, 17) of the two blocks are parallel to one another and at least one and preferably both of the facing inner surfaces (13, 14) of the blocks are inclined with respect to said major outer surfaces. The wedge has two converging surfaces which lie parallel to and make sliding contact with the facing inner surfaces respectively of the two blocks. Side flanges on the blocks maintain alignment between the wedge and the blocks in a direction of movement of the wedge. A threaded drawbolt (22) for moving the wedge has a head (22) at one end. The drawbolt extends into a hole (19, 20) in the wedge from the thin end thereof and engages with a thread in the hole (19) or with a threaded nut (29). A washer (25) between the head of the drawbolt and an end surface of each of the two blocks maintains alignment between the two blocks in the direction of movement of the wedge. <IMAGE>
Patent GB-2128319-A (GB)
Title: Heat pipes
Inventor: WHITE WILLIAM JOHN
IPC: F28D15/04
Filed: 1983-09-28
Abstract: The starting ability of a heat pipe, having an inner tube (12) separating the vapour-phase path (inside the inner tube) from the liquid-phase return path (annularly outside it), under "negative slope" conditions i.e. with the heat pipe extending (slightly) upwardly towards it heat-absorbing and (10A) is improved by providing not only a bend (10C) so that a part of the heat pipe also extends upwardly towards the heat-releasing end (10B) but also by providing a reservoir (15) communicating, in that part, with the vapour-phase path (instead of the liquid-phase path). A further improvement is then obtained by providing (i) at the heat-absorbing end a weir (18) tending to separate liquid surface levels in the liquid-phase and (flooded) vapour-phase paths and (ii) a saddle-like blocking element (19) blocking the upper part of the annular liquid-phase path near the said bend. <IMAGE>

Patent GB-2132841-A (GB)
Title: Method and apparatus for the digitalization and storage of ultrasonic information
Inventor: RENZEL PETER
IPC: G01N29/44
Filed: 1983-12-13
Abstract: For the logarithmization and digitalization of analog signal voltages, these voltages are generated cyclically as recurring real-time images (A- images). The signal voltages are amplified 5 and compared 6 with a preselected threshold voltage. The resulting digital values are fed to a shift register 8. On expiry of each real-time image, the shift register contents are transferred to a memory 9. The amplification is reduced between the recurring real-time images, in a logarithmic graduation from one cycle to the next. The process stops when a flip-flop 10 fails to detect non-zero digital values from register 8. <IMAGE>

Patent GB-2140767-A (GB)
Title: Bag clipping apparatus
Inventor: HARTMANN JOHANNES
IPC: B65B51/04
Filed: 1984-05-24
Abstract: For sealing bags (3) containing a packaged product (2), especially a loaf of bread, there is used a belt conveying arrangement (4) consisting of a single endless or two endless conveyor belts which form a belt inlet (5) and a belt discharge (6) one after the other in the direction of passage ("A") of the filled bags, and a clipping arrangement (7) mounted between the belt inlet and discharge (5, 6) so that it can swivel backwards and forwards about an axis (22) in the direction of passage. The belt inlet and discharge run continuously and synchronously, and the clipping arrangement (7) is synchronised in its swivelling movement to the belt speed. For the clipping operation, the belt discharge (6) is lowered in synchronisation with the swivelling motion of the clipping arrangement (7), so that the bag (3) is clipped at half the height of the packaged product. During the sealing operation, as a result of the synchronous movement between the clipping arrangement (7) and the belt discharge (6), a relative state of rest obtains, which ensures satisfactory clipping of the bag (3). <IMAGE>

Patent GB-2146190-A (GB)
Title: Oscillation generator arrangements
Inventor: EMERY DEREK GEORGE
IPC: H03L7/14
Filed: 1984-08-20
Abstract: A single microprocessor services thirteen VCO's each providing a different channel frequency. A variable counter controlled by the microprocessor is connected to the output of each VCO via a multiplexer in turn. The time period from the o/p of the counter is crosschecked by the timer-counter in the microprocessor. This timing (which is derived from the microprocessor's clock) is accurately determined by a master oscillator. Using a D to A converter connected via another multiplexer to a sample & hold circuit on the control input of each VCO the microprocessor sets the control voltage for each dependent on the result of the count crosscheck. Since the voltage on the sample hold circuit decays with time each VCO voltage is refreshed by the microprocessor at periodic intervals using the voltage figure determined on the last respective frequency check. <IMAGE>

Title: Improvements in spectacle frames
Inventor: MIKKELSEN JORGEN VESTERBY
IPC: G02C11/02
Filed: 1985-10-10
