Patent GB-2163250-A (GB)
Title: Counting apparatus for radioactive sample filter papers
Inventor: ARKLEY JAMES
IPC: G01T7/10
Filed: 1984-08-15
Abstract: A plurality of stations C1-C6 at which radioactive emissions from a filter paper can be counted are angularly disposed about a turntable 20 carrying radial arm 22 which can be moved to insert and withdraw a filter at the stations and at a loading station LM and an unloading station UM. Thus a plurality of counters are served by a single transfer mechanism. Optical means at each station C1-C6 sense the presence of a filter and initiate counting of alpha and beta emissions. <IMAGE>

Title: D.C.-D.C. converter circuit
Inventor: JANSSON LEONARD ERIC
IPC: H02M3/337
Filed: 1984-09-05
Abstract: A d.c.-d.c. converter circuit comprises a transformer (3) an input winding (17) of which is connected with alternating polarity across a pair of input terminals (1, 2) via a choke (7) by means of a pair of switches (8, 9). In order to control the voltage across a pair of output terminals (4, 5) in spite of the constant-current property of the choke the output terminals are fed from the transformer via a peak rectifier circuit (6) and the switches are controlled by a switching signal generator (12) in such manner that the periods when each is closed overlap the periods when the other is closed by an amount which depends on the value of a control signal at a control signal input (13), the durations of the periods when only one switch is closed being kept equal to one half the period of the resonant frequency of the resonant circuit constituted by the input winding (17) and a capacitor (16). The connection from the choke (7) to the centre-tap (37) of the input winding may be instead to one end (32) of the input winding, provided that another choke connects the relevant input terminal (1) to the other end (33) of the input winding. <IMAGE>

Patent GB-2176023-A (GB)
Title: An optical switch or sensor
Inventor: BAGSHAW DR JOHN MARTIN
IPC: G02B6/35
Filed: 1985-06-07
Abstract: An optical switch or sensor may be formed from a single bimorph member bimetallic strip or bimagneto strictive which is formed with a slot 9 which divides it into two parts. A mounting member is moulded on to the free ends of each bimorph part and may be divided into two by the same slot as divides the two parts of the bimorph.

Title: Extrusion control
Inventor: TWIST REGINALD JAMES
IPC: B29C48/285
Filed: 1986-02-28
Abstract: @ An extrusion process is controlled by feeding the material to be extruded from a supply station (5) to an extruder (1) and repeatedly weighing the supply station to calculate the throughput of the extruder. The initial line speed necessary to produce a predetermined weight/metre of extrudate is calculated and the line speed is adjusted accordingly. Subsequently, the throughput and the line speed are increased simultaneously, such that the weight/ metre is maintained substantially constant until any one of a plurality of parameters such as line speed, screw speed, motor load current, extrudate temperature, melt pressure, etc reaches a predetermined maximum value. Thereafter either the line speed or extruder throughput is adjusted such as to maintain the weight/metre of the extrudate substantially constant at the desired value.

Title: Variable pitch blades with cooling air control
Inventor: WOLLENWEBER GARY CRAIG
IPC: F01D5/08
Filed: 1986-04-03
Abstract: In a gas turbine engine having a variable pitch rotatable airfoil, cooling air control means comprise a platform 26 fixedly attached to a radially inner end of each airfoil. The platform is generally positioned on a rotatable annular surface 16, which surface defines radially outer and inner spaces. In a first position (Figure 2 not shown), an edge portion of the platform substantially conforms to the annular surface. In a second position, the edge portion 38 is displaced radially outwardly from the surface thereby allowing cooling airflow from the outer to the inner spaces via the opening 40. In an alternative embodiment the opening 40 communicates with a diffuser for increasing the static pressure of the air flow. <IMAGE>

Title: Improvements relating to braided line
Inventor: BURGESS PAUL DAVID
IPC: A01K91/00
Filed: 1986-06-13
Abstract: Braided line, particularly leaders for fly fishing, is immersed in a liquid and withdrawn after a time. The liquid remaining on the line sets into a skin or coating, entrapping air within the line. The buoyancy is thus modified. Variations can be achieved by relaxing and stretching the line to work more liquid in, or by introducing additives to the liquid. The treatment may not be uniform along the line.
Patent GB-2197750-A (GB)
Title: Discharge tube devices
Inventor: WEATHERUP CLIFFORD ROBERT
IPC: H01J17/28
Filed: 1986-08-30
Abstract: A discharge tube device, such as a thyratron, may be able to conduct current for only a limited time because of migration of gas within its envelope to one end of the device. Postive ions passing from the anode to the cathode via apertures in the grid structure tend to cause non- ionised gas molecules to travel in that direction also. By providing a gas return path and means for conducting heat from the grid and anode region, current may be conducted for relatively long periods, to give higher power operation. As described, gas travels along the dotted lines by virtue of apertures 11 in cathode heat shield 10. Cooling may be achieved by providing a generally cylindrical metal portion 8 in the envelope which may either be attached directly to grid structure 4 (figure 2, not shown) or by metal rods 9. The anode stem may be hollow for receipt of cooling air or oil. <IMAGE>

Title: Free-piston I.C engine
Inventor: RYMER BARRY JOHN
IPC: F02B75/04
Filed: 1988-01-21
Abstract: An engine comprises first and second interconnected pistons 7, 8 which define four variable volume chambers in a block 1. Gas in the chamber 21 is compressed by the second piston 8 during the combustion stroke of the engine to provide resilient means for urging the first piston 7 back along the cylinder during the return stroke. During normal running, gas drawn into chamber 17 through manifold 26 is compressed for storage in a cross scavenging reservoir 9, to scavenge the combustion chamber 4 after every combustion stroke. During start up however, pressurised gas from line 33 is supplied to the chamber 17 so as to move the second piston 8 to the left to compress the gas in chamber 21, and suitable operation of solenoids 34 and 36 causes reciprocation of the pistons 7, 8 until normal running is established. Chamber 27 forms a compressor chamber in which gas drawn in via manifold 10 is, in normal running, compressed for supply to a reservoir via line 41, 33 or, during start up, exhausted to atmosphere via line 45. <IMAGE>

Filed: 1988-07-18
Abstract: Apparatus for striking a material comprises a square support tube 13 adapted to be moved by boom 16 of a hydraulic excavator towards and away from the material (e.g. concrete). An elongate striker bar 17 is mounted in the tube 13 for striking the material and is axially slidable in the tube 13 during downward movement thereof so that once the tube 3 has stopped moving downwardly, the bar 17 will continue downwards under gravitational force and strike the material. Force transmitted through a tube plate, a tyre and a bar plate 30 can move the bar 17 downwards before the tube 13 stops moving downwardly. A spring acting between the tube and the bar may too assist such movement. The bar 17 is raised by plate 13 cooporating with tyre 22 (shock absorber) and plate 19 of bar 17. A guard 41 may be provided around the tyres 22. The striker may include a removal striking part 34 having desired tip shapes. The tube 13 may include internal wear plates to engage bar 17.
