Patent GB-2258290-A (GB)
Title: Flow control system
Inventor: HOLMES PAUL
IPC: B65G53/46
Filed: 1992-07-27
Abstract: A flow control system of use in discharging bed material from a fluidised bed comprises a first ball valve (1) and a second ball valve (13) which defines a flow passage of greater diameter than that of the first ball valve. The two valves are connected by a connecting pipe member (8) having an internal diameter smaller than the flow passage diameter of the second ball valve (13) and not less than the flow passage diameter of the first ball valve (1). An inlet means (16) for introducing a gas into the connecting pipe member (8) is provided. In use the valve system is usually mounted substantially vertically and connected to a discharge means which permits flow of fluidised bed material from the fluid bed. The valve system permits controlled discharge of bed material from a fluid bed with reduced wear on ball valve seats and a positive gas sealing system when closed during operation of the fluid bed. <IMAGE>

Title: Producing tuning signals using a variable resistance controlled VCO
Inventor: HOLDEN ROBERT
IPC: H03J1/00
Filed: 1992-08-19
Abstract: A circuit of a tuning device for tuning a radio transceiver, the circuit comprising a variable impedance device 14, which consists of a pair of variable resistors having an open circuit between their tracks, the "wiper-arm" 14a of which is connected to a voltage controlled oscillator (VCO) 15. The voltage controlled oscillator may suitably comprise a CMOS 4046 integrated circuit. The voltage controlled oscillator outputs a stream of pulses, having in this case a 1:1 mark:space ratio, to the transceiver units micro-computer (not shown). At the centre point of the tracks of the variable impedance device 14 there is a null position corresponding to an open circuit. As the user turns a dial this centre position is indicated by a notch. As the wiper arm is moved from the centre position towards either extent, the value of the voltage at the VCO terminal 15a increases. Because of this the rate of production of pulses, ie. the frequency of the pulse stream output by the VCO 15, increases accordingly. Each pulse represents an increment or decrement of the frequency to which the radio transceiver (not shown) is tuned. <IMAGE>

Title: Spinning reel
Inventor: HITOMI YASUHIRO
IPC: A01K89/01
Filed: 1992-08-26
Abstract: A spinning reel has a rotor 4; a bail 7 pivotally connected to the rotor 4 through a pair of oscillatable arms 4A to be switchable between a line takeup position and a line release position; an anti-reverse mechanism B including an engaging member 15 and an engageable member 16, and operable by an arm 18 on a shaft 19 mounted on a reel body 2 to be switchable between a position to allow free rotation of the rotor 4, and a position to prevent backward rotation thereof and allow rotation only in a line winding direction; and a switching mechanism A including a control member 14 mounted on one end of the rotor 4 for switching the bail 7, and a cam 12 formed integral with the reel body 2 for contacting the control member 14. The switching mechanism A is operable, through interaction between the control member 14 and the cam 12 occurring with rotation in the line winding direction of the rotor 4, to switch the bail from the line take up position to the line release position. The anti-reverse mechanism B has a range of play for allowing the rotor 4 to rotate in a line unwinding direction while the control member 14 moves into contact with the cam 12. This enables the bail 7 to be switched to the line release position smoothly even when the rotor 4 is prevented from rotating backward. <IMAGE>

IPC: F24D5/08
Filed: 1994-08-10
Abstract: A radiant tube space heating appliance has a heat projecting cowling (20) enclosing the sides of radiation tube (10) remote from the area towards which heat is to be directed.
