Title: Tobacco smoke filters
Inventor: LUKE JOHN ANTHONY
IPC: A24D3/04
Filed: 1983-01-13
Abstract: A smoke filter for a smoking article (e.g. a cigarette) comprises a filter plug (4) having an airflow duct whose floor (5) extends along the filter plug from the mouth end of the plug such that the end of the duct (8) remote from the mouth end is deeper than the end of the duct at the mouth end, with a region of progressively decreasing depth from the deep end towards the shallow end. The at least one duct may comprise a plurality of grooves (8) equiangularly spaced around the periphery of the filter plug, in which case it is possible for the grooves to extend helically and to be divided into sets of opposite hand such that each groove of one set intersects several grooves of the other set. Alternatively, the airflow duct may comprise a single annular groove extending around the filter plug with a shallower side at the mouth end of the plug and a deeper side remote from the mouth end, in which case a relatively stiff tipping (7) is required. In all cases the tipping (7) includes ventilation perforations (9) communicating with the deeper end of the air duct (8). <IMAGE>
Patent GB-2133816-A (GB)
Title: Fabric material
Inventor: TOUGH WILLIAM HAMISH
IPC: D06C3/00
Filed: 1983-01-18
Abstract: A woven fabric material is formed from tapes of synthetic resinous material such as polypropylene, either the warp tapes or the weft tapes having discontinuous longitudinally extending localised weakened areas formed in them, for example discontinuous longitudinally extending grooves in the tapes. The woven fabric is then stretched by stretching longitudinally and at a raised temperature that set of warp tapes or weft tapes which does not have the weakened areas, thereby causing the tapes with the weakened areas to split at those areas and open up to take on the appearance of a network. The stretched woven fabric material is cooled in the stretched condition so that the final stretched woven fabric material obtained has a substantially greater area and a lesser overall thickness than the base woven fabric, i.e. the fabric before it was stretched.

Title: Improvements relating to piloted solenoid valves
Inventor: HAFELE CARL HEINZ
IPC: F16K31/40
Filed: 1983-05-26
Abstract: A piloted solenoid valve has a main valve seat (14) and a differential piston (10) closing the same, the back of the piston bounding a chamber (36) communicating with a valve entry (2) by way of small gap cross-sections. A pilot valve is axially aligned with the differential piston (10) and seals off the chamber (36) behind the piston (10) from a lower-pressure chamber (37). A pull rod (28) is rigidly secured to a plug (23) of the pilot valve and acts on the differential piston (10) in an opening direction after a partial movement of the pilot valve and, upon the differential piston (10) making an independent opening movement, extends thereinto without impeding its movement. For positional indication, an axially guided rod (35) is rigidly connected to the pilot valve spindle (22) and extends by way of the solenoid to a position indicator (8) disposed thereafter. <IMAGE>

Title: Signal processing for interference suppression
Inventor: BAGLEY GEOFFREY CHARLES
IPC: G01S7/36
Filed: 1983-08-08
Abstract: A signal processor for detecting a small signal Sw in the presence of a larger amplitude signal Su divides an input signal into two channels A, B. A limiter (12) of variable limiting action is arranged in one channel. In the other channel variable attenuator (14) and phase shifter (15) are arranged to equalise the power leaving both channels A, B. Both channels are combined so that the limited signal perturbs the unlimited signal to suppress the larger input signal Su. In one example the channels A, B are combined in a power combiner (16), one channel having a delay of  pi  radians. In another example (fig. 3, not shown) the two channels A, B are combined in a mixer (25) and filter (26). <IMAGE>
Patent GB-2145022-A (GB)
Title: A riveter
Inventor: NICHOLS GEORGE WILFRED
IPC: B21J15/10
Filed: 1983-08-16
Abstract: Relative movement together of upper and lower tool holders 11 and 8 respectively of a riveter is carried out in two stages. The first stage of movement, in the illustrated embodiment, is performed by actuating a pneumatic cylinder 9 which allows the upper tool holder to drop under the action of gravity. The force applied is thus very small enabling the operator with safety to manipulate various parts of a work-piece 6 so that the rivet R passes through holes 6e. Only when the upper tool holder is in its lowermost position, when there is insufficient space above the work piece for the operator to insert his fingers, is the upper tool holder 11 locked by pneumatically driving a bolt 16 so that it engages the upper surface 18A of the tool holder 11. The lower tool holder 8 is then driven rapidly up and down a short distance 11 to deform the rivet. This distance 11 is insufficient for insertion of the operator's fingers and in any case the lower tool holder is guarded by suitable means against access by the operator. <IMAGE>

Patent GB-2144861-A (GB)
Title: Grain sensing systems
Inventor: YEMM IAN WILLIAM
IPC: A01D41/127
Filed: 1984-08-06
Abstract: Grain loss sensors (4) are fitted to a combine harvester and an indicator (5) displays the extent of the loss. To cope with different weights of grain and corresponding variations in noise level from the sensors, the sensors outputs are subject to a continuously adjustable noise-excluding threshold dependent on the average amplitude of signals derived from the harvested product. A separate detector (1) in a grain only path may provide the threshold determinant, or it may be derived from one or more of the grain loss sensors. The threshold circuit (3) may incorporate three comparator circuits and a pulse length control gate. The signal from averaging circuit (2) is applied to a first comparator set to reject noise. The gate only passes accepted pulses in excess of a pre-set length, which are then applied to the other comparators, which drive a voltage ramp to produce the sensitivifty or threshold level. <IMAGE>
