Patent GB-2119617-A (GB)
Title: Mycorrhizal seed pellets
Inventor: WARNER DR ANNE
IPC: A01C1/06
Filed: 1982-04-22
Abstract: It has been a problem to pellet seeds with inoculum of the beneficial VA mycorrhizal fungus. Hitherto, clay or soil pellets have been tried but they are difficult to adjust to a suitable moisture content and the pellets are too heavy, and there is a problem in placement of the seed so as to ensure that the radicle will grow through the pellet and thereby pick up the desired fungal infection. It has now been found that satisfactory pellets can be made using peat and a binder instead of soil and that even when the pellet is dried considerably the inoculum retains infectivity for at least 6 months, using sphagnum moss peat. The composition in uncompacted and compacted forms and a method of growing plant from seed are claimed. The invention is useful for improving the condition of poor soil, e.g. filled-in gravel pits or coal mine spoil tips.

Title: Welded stator vane assemblies for turbomachines
Inventor: LANE KEITH
IPC: F01D9/04
Filed: 1982-12-24
Abstract: A method of manufacturing a welded stator vane assembly for a turbomachine. The method comprises the steps of providing radially spaced inner and outer slotted members 38, 40 and a plurality of vanes 14 each of which has end fittings 64, 66 at each end. The end fittings 64, 66 are slotted into the slots 48, 52 of the inner and outer members 38, 40 and the end fittings are welded to the members 38, 40. In effect, the slotted members 38, 40 define a plurality of "spacers" 70 between the slots 48, 52 interconnected by the metal of members 38, 40 that define the base of the slots 48, 52. Subsequently, this metal is machined away to expose the welds and leave two concentric rings interconnected by the vanes. The rings consist of alternately end fittings and "spacers". <IMAGE>

Title: Frequency control device to synchronise an oscillator with an external signal of very accurate mean frequency but having a high jitter
Inventor: CALVEZ JEAN-LUC
IPC: H03L7/113
Filed: 1983-04-27
Abstract: A frequency control device includes an analog phase locked loop, which operates on initial switch-on, and a digital frequency locked loop which takes over from the analog loop when it is locked to control the same voltage controlled oscillator (OCT) so as to ensure faster locking. Control of the oscillator successively by the two loops uses a switching circuit (ANA) with two inputs, one for the analog loop (OCT, C???, F) and one for the digital loop (OCT CF, P). This switching circuit includes a sampler- coder (EC), an up-down counter (CD), a register (RE), and a D/A connector (CNA). The sampler-coder input is the one for the phase loop, and the inputs for the counter are those for the frequency loop. The reference signal for both control loops is the external signal (E). In the phase loop configuration the sampler-coder, up- down counter and register are driven by a high frequency signal (T1) of about 1 MHz. In the frequency loop configuration the sampler-coder is ineffective and a lower frequency signal (To) of about 1 Hz drives the register. The device is useful in digital (PCM) telephone exchanges. <IMAGE>

Title: Dispensing fluent material
Inventor: SADLER ROBIN WILLIAM
IPC: G01G13/18
Filed: 1984-07-03
Abstract: An arrangement for calibrating feeders such as are used for dispensing concentrated dry feed to animals comprises a container (1) for receiving material from a feeder (10), the container being arranged such that its vertical location depends on the weight of the container and contents; two vertically spaced sensors (7,8) or emitters fixed adjacent the container; and a cooperating emitter (9) or sensor fixed to the container, each emitter/sensor pair being arranged to generate a signal when in horizontal alignment. In use, material is fed to the container from the feeder at a constant flow rate and the time interval between generation of signals or horizontal alignment of the emitter or sensor associated with the container with the two fixed cooperating components is measured. This time interval represents the time required to disperse a given weight of material, and is used to provide a basic time unit for calibration of the feeder. <IMAGE>

Title: Fluid-pressure-actuated motor
Inventor: WALSWORTH FRANK J
IPC: F04B43/06
Filed: 1984-11-23
Abstract: The crankcase 67 of an internal combustion engine 8 generates alternating high and low pressure which is fed through distributor 151 to the high pressure chamber 125 and low pressure chamber 123 of motor 13. Non-return valve 171 allows fluid under pressure to enter chamber 125 but not to leave it and valve 169 permits the evacuation of chamber 123 but not its pressurization. This results in a pressure difference across piston 127, under which it moves against the bias of spring 141 until valve 193 opens to remove the differential, when spring 141 drives the piston back to the point where studs 221 shut valve 193 and so cause the cycle to repeat. The stroke of piston 127 is governed by the pressure difference across it and hence by the amplitude of the crankcase pressure. Valve spring 201 is sufficiently compressed after a short stroke to overcome the pressure across 193 when this is low, but a high pressure will drive the piston to the point where post 302 opens the valve. The motor is used to drive fuel and oil pumps for engine 8. <IMAGE>

Title: Drive arrangement for a pump/agitator in a cooler
Inventor: FILMER MICHAEL JOHN
IPC: H02K7/11
Filed: 1984-12-03
Abstract: A cooler comprises a tank (31, Fig. 2 not shown) containing liquid and a motor/pump/agitator unit 200, the motor 12 producing a magnetic drive which is transmitted to a magnetic slug 60 connected to pump impeller 19 and/or agitator 24. As described, the motor 12 has its own plastics housing 13 and causes an annular magnet (not shown) to rotate, the magnet surrounding part of a plastics housing 16 for the slug. The impeller 19 pumps water from the tank round a recirculation system. The motor 12 is sealed off from the tank and there is therefore no need for a drive shaft to pass through the housing 13 as in the prior art. <IMAGE>

Title: Brake control system
Inventor: POOLE JOHN DAVID
IPC: B60T13/58
Filed: 1985-02-11
Abstract: o A brake control system for a multiple unit train of mixed motor cars and trailer cars - of the type usually to be found operating as metro or mass transit trains - and in which the motor cars have dynamic brakes operation of which is blended with, but given preference over, the friction brakes of all units. A brake demand signal calling for a given level of train retardation is weighted on each vehicle, according to the load of the vehicle, and the level of dynamic braking effort invoked on each motor car is limited in accordance with a maximum adhesion level calculated in proportion to the measured load of that car. In a modified arrangement the adhesion level is calculated in accordance with the load of the lightest loaded motor car. Signals representing the amount of dynamic brake effort achieved by each motor car is supplied to a trailer car and subtracted from the load weighted braking effort for the trailer car and the result used to actuate the friction brakes of the trailer.
