Patent GB-2102989-A (GB)
Title: Speed governor
Inventor: WALFORD ALEXANDER GEORGE
IPC: G05D13/24
Filed: 1982-07-15
Abstract: The invention concerns hydraulic speed governors having a flyweight system 1 driven by a prime mover at 14 to move a pilot valve 24 as a means of directing oil to and from a power piston 3 which in turn controls the energy supple of the prime mover e.g. by operating a fuel valve at 22. This type of governor requires negative feedback to provide a stable control loop. Conventional governors have a fluid operated feedback mechanism (35 and 45) utilising a restrictor 8, i.e. bleed valve, to dissipate the feedback pressure slowly, whatever the position of the pilot valve. This can lead to instability of operation in certain cases. In the present invention access to the bleed valve (i.e. restrictor 8) is prevented for positions of the pilot valve (2) off the equilibrium position e.g. by making the connection between restrictor 8 and chamber 45 through a load 29 of the pilot valve 27 whereby communication is blocked when the valve 27 moves from the equilibrium position. By not allowing the feedback pressure to return to normal until the pilot valve is in its neutral or equilibrium position a bias force is maintained on the pilot valve which tends to prevent instability of operation. <IMAGE>

Title: Mixture of vinylidene chloride copolymer and ceramic material and method of use thereof
Inventor: LIVINGSTONE COLIN DAVID
IPC: C08K3/00
Filed: 1982-09-28
Abstract: A coating or moulding composition comprises a mixture of ceramic particles and an aqueous vinylidene chloride copolymer emulsion. The composition can be applied to existing wall surfaces or used to make building panels and slips. These can be made relatively light in weight compared with conventional products. By use of particles of ceramics such as brick, stone, slate and marble, the compositions when set resemble conventional building materials, so that the compositions are useful in the rehabilitation and repair of existing buildings. The composition has the special advantage that it will bond to a damp surface. The composition can be used in combination with low density, low heat conductivity materials to provide panels and walls which are tough, light in weight, highly heat-insulating, fire-resistant and water-proof.

Title: Audio transformers for safety isolation
Inventor: LACEY PHILIP EDWIN JAMES
IPC: H01F27/32
Filed: 1983-07-13
Abstract: A transformer comprises a laminated core 10 having a figure-of- eight configuration, the central limb of which carries a rigid insulating bobbin 12 on which are concentrically wound the primary and secondary windings 14 and 16. The core 10, bobbin 12 and windings 14 and 16 are designed so that, in the assembled transformer, there are spaces between the outer winding and the core 10. These spaces are filled with a semi-rigid curable insulating compound 26 in order to prevent breakdown between the winding and the core 10 of the transformer which, in use, are at different potentials. The concentric windings 14 and 16 are isolated from one another by a layer of insulating tape 30. The tape used is extremely extensible so that its longitudinal margins can be stretched to extend radially outwards and over the edges of the end flanges 20 of the bobbin 12. The tape insulation 30 thus extends around the outer winding 16 without breaks or interstices. Such transformers can withstand high voltages and can, therefore, be used for providing safety isolation, using a standard bobbin in a wide range of sizes. <IMAGE>

Title: Wear monitoring
Inventor: GREEN ROBERT JAMES
IPC: B65B19/28
Filed: 1983-07-26
Abstract: Wear associated with a moving part 5 of a cigarette packaging machine operating in a succession of machine cycles (e.g. a plunger 5 for transferring a cigarette bundles 4 in a partly formed packet from an arbor 2 in an arbor drum 1 into a packet 6 of a drying drum 3) is monitored by generating a first signal at a position and direction of movement of the moving part 5, and generating a second signal at a predetermined position of a second moving part (eg the arbor drum 1). The second moving part does not wear to the same extent as the first moving part and therefore indicates a cyclic position of each machine cycle. A third signal is produced indicative of the time interval between the first signal and the second signal, and a comparison is made with a reference signal to determine the extent of wear. The reference signal or the signal to be compared may be adjusted to take into account changes in speed of the machine. <IMAGE>

Patent GB-2153487-A (GB)
Title: Cast metal connecting rod construction
Inventor: SCHULTE GUNTER
IPC: F16C7/02
Filed: 1985-01-10
Abstract: A cast iron connecting rod (1) has a shank (4) of a substantially I-shaped cross section, the structural design of the shank being such that the surface area of the cross-sectional surfaces along the shank, at least in the partial areas, remains the same when the outer contour of the shank varies. The wall thickness of the web (6) of the connecting rod shank (4) varies in the region between the "little end" (small bearing eye 3) and the "big end" (large bearing eye 2) of the connecting rod (1). This measure aids the casting advantage of controlled hardening as hardening will progress from a mid-region A-A of least wall thickness whereby the rapidly hardened region is used as a cooling region for the further hardening of the shank. Thus, the surface area of the cross-sectional surface of the shank (4) remains substantially constant, along part of its length, when the outer contour of the shank varies and hence when the surface/volume ratio changes. <IMAGE>

Patent GB-2521090-A (GB)
Title: Multi-function adaptive processor
Inventor: RICKARD ROBIN PAUL
IPC: H01Q3/26
Filed: 1986-03-04
Abstract: An adaptive processor for use with multiple input signals such as those from an array of antenna elements employs a weight update correlation loop algorithm of the form Wn = (1 - Ïµ) Wn-1 - Âµ En*Sn where Wn is the updated weight, Ïµ is an integration loss factor, Âµ is the update gain, En is a complex input (element) signal and Sn is a complex sum signal. The integration loss factor is varied for each input signal and controlled as a function of the input signal power. Preferably, the control algorithm is power normalised, i.e. the update gain factor is variable and inversely proportional to the input signal power. The use of a variable integration loss factor enables a fixed absolute sensitivity (turn-on) threshold to be maintained. The power normalised algorithm is preferably implemented using two automatic gain control systems and logarithmic coding of power levels to reduce complexity.
