Patent GB-2156699-A (GB)
Title: Pneumatic conveying and material blending apparatus and method
Inventor: ROMANCHIK ROBERT E
IPC: B01F33/40
Filed: 1984-04-04
Abstract: A bin (15) has an open-ended vertical column (25), whose bottom (30) is spaced from the bottom (18) of the bin (15) mounted therein. A pneumatic conveying system (8) supplies material to be blended from a source (5, Fig. 1) to the material inlet (17) in the bottom of the bin (15) and conveys the material upwardly through the column (25) to discharge it from the top thereof over the top surface of material already in the bin (15), with the aid of a defector (35). Material already in the bin (15) is drawn into the bottom of the column (25) and so is blended with material being conveyed to the bin (15). Booster gas can be supplied to the bin (15) through a gas permeable surface (50) adjacent the bottom of the column (25), by using a vacuum applied through a vent (19) or by a blower (55, Fig. 1) supplying gas directly through conduit (52) to a manifold (51) surrounding the surface (50). The outlet for blended material (40) is coextensive with the inlet (17) of the bin (15). The material may be recirculated internally by supplying only gas through the inlet (17).   <IMAGE>
Patent GB-2139022-A (GB)
Title: Ballast circuit for lamps with low voltage gas discharge tubes
Inventor: DAVENPORT JOHN MARTIN
IPC: H05B35/00
Filed: 1984-04-11
Abstract: The circuit operates directly from an applied 220 volt, 50 Hz or 120 volt, 60 Hz A.C. voltage source and comprises a capacitor C1 connected serially with both an incandescent filament and the gas discharge tube. If desired, the incandescent filament may be replaced with a resistive element. The value of the capacitor is selected so as to reduce the applied 220 volt, 50 Hz or 120 volt, 60 Hz A.C. source to a desired range for operating the circuit in a manner to develop a desired reduced voltage for operation of the gas discharge tube. The reduced operating voltage correspondingly reduces the restrike voltage that may be necessary to operate the gas discharge tube during restrike conditions. The reduced operating voltage of the gas discharge tube readily allows for the development of the restrike voltage directly available from the typical 220 volts, 50 Hz or 120 volts, 60 Hz A.C. source. The circuit arrangement further provides for an automatic restrike voltage under reduced voltage A.C. source conditions, a voltage developed across the capacitor C1 then being additive with the A.C. source voltage to form the restrike voltage (Fig. 7). <IMAGE>

Patent GB-2155823-A (GB)
Title: Improvements relating to tool holders
Inventor: ISAAC STEPHEN JOHN
IPC: B23B31/00
Filed: 1985-03-23
Abstract: A rotatable or stationary working tool (1) has an extending shaft (3) which is received in a corresponding hole in an adaptor (2). A projection (5) on the tool (1) inter-engages with a corresponding ground slot in the end face of the adaptor (2) so that the two parts (1) and (2) cannot rotate with respect to one another. Furthermore, the plane of symmetry of the nose (5) is offset from the axis of the shaft (3) so that the tool can be inter-engaged with the adaptor (2) in one attitude only. A conical recess (7) formed in the shaft (3) receives the conical nose of a grub screw (9) which is threaded into a hole (8) in the adaptor (2). The centre line of the recess (7) is slightly offset outwardly from the centre line of the grub screw (9) when the two parts are fully inter-engaged so that tightening of the grub screw (9) pulls the tool (1) back against the adaptor (2) to create a tight positive location between the two parts (1) and (2). <IMAGE>

Title: Apparatus for testing coins of various values
Inventor: LANG PETER
IPC: G07D5/02
Filed: 1985-08-21
Abstract: Apparatus for testing coins of various values includes a first detector (6) for testing the coin alloy, which detector successively receives a.c. voltages of various frequencies from an audio frequency generator (15). A stopper is disposed in a rolling track for the coins, and a second test detector (8) is disposed downstream of the stopper, for testing the diameter of the coins. An evaluation means (22) controls the audio frequency generator (15) and change-over switches (16, 17, 18) for transmitting a test voltage (UoC) to a voltage detector (21), and stores the output voltage (Um) thereof in a memory (26). When the apparatus is set in operation, prior to the coin testing operation, calibration of the test detectors (6, 8) is carried out in order to render ageing, stray effects and fluctuation in temperature inoperative. After calibration and all operations of testing a coin, the associated values in the memory (6) are compared and a corresponding signal is produced. <IMAGE>
