Title: Improvements in electromagnetically operated valves
IPC: F15B21/044
Filed: 1970-12-29
Abstract: 1286950 Valves G KROMSCHRODER AG 29 Dec 1970 [9 Jan 1970] 61672/70 Heading F2V [Also in Division H1] An electromagnetically operated valve comprises an armature 23 formed as a piston moving in a cylinder 21 filled with retarding fluid, the armature including a ring 24 and a disc 25 both made of a material whose coefficient of expansion is at least ten times that of the material of which the cylinder is made. The cylinder may be made of aluminium and the disc and ring of polyacetal.

Patent GB-1256030-A (GB)
Title: Fiber blending system
IPC: D01G13/00
Filed: 1969-12-19
Abstract: 1,256,030. Blending fibres. FIBER CONTROLS CORP. 19 Dec., 1969 [27 June, 1969], No. 62039/69. Heading DIF. A method of blending fibres comprises depositing fibres in a number of weighing pans, transferring the fibres from the pans to a conveyor when there is a predetermined weight in each pan, moving the conveyor through a fixed distance after each fibre transfer and producing a signal to indicate a malfunction when the conveyor remains stopped for longer than a predetermined period. Individual feed means feed fibres to each pan. When a predetermined weight is in a pan a switch is operated to stop the feed. When all the feeds are stopped the fibres are transferred to a stationary conveyor beneath the pans. The conveyor is then started until it operates a stop switch, the "sandwiches" of fibres formed being fed to a further processing device. The system is arranged to continuously re-cycle. When the system runs correctly the stationary phases of the conveyor are of approximately the same length. A time-delay mechanism is incorporated in the control circuit so that if the conveyor remains stationary for a substantially longer period, a horn is sounded, a light operated or a signal fed to a recorder to indicate a fault. A variety of faults are thus detected, e.g. if fibres are not being fed to the pans or if the fibre transfer mechanism is faulty the fibres will not be dumped, and the conveyor will remain stationary thus indicating the fault.

Title: Control for lamphouse of enlarger head
IPC: G03B27/54
Filed: 1979-03-14
Abstract: This specification relates to a microprocessor control for a lamphouse. The lamphouse 1 is used for the production of prints on variable contrast paper and comprises a first tungsten filament lamp 4 from which light passes through a colour selective filter 6 which passes light in one of two mutually exclusive wavebands. A second filament lamp 5 and filter 7 passes light in the other of the two mutually exclusive wavebands. A diffusing screen 12 is placed to pass the filtered light out of the lamphouse and through a transparency 15 which is to be printed. Between each lamp and an alternating voltage source is connected a bidirectional thyristor, whose phase angle of conduction is determined by a microprocessor according to data stored in a read-only memory and by single manual controls for selecting alternative addresses in the memory according to the contrast of print to be made. The data stored in the memory is chosen to cause the bidirectional thyristors to adjust the currents through the two lamps so that the energies of the light in the two mutually exclusive wavebands vary substantially in inverse proportion as the chosen contrast of print is varied and the total light intensity is controlled to suit the sensitivity of the material at different contrast grades to ensure equal exposure for each contrast grade. <IMAGE>

Title: Arrangement for supplying fluorescent lamps with power at two levels and lighting installation incorporating such an arrangement
IPC: H05B41/42
Filed: 1979-03-15
Abstract: A circuit for supplying power to a fluorescent lamp 1 comprises a main supply circuit 3 which enables the lamp to operate at its maximum level of illumination, and a switch 5 which connects an auxiliary circuit 4 to the main supply circuit so that the lamp operates at a reduced level of illumination. The switch 5 is a relay having a coil 11 and contacts, a, b, c, d, the contacts a, b being closed when the relay is de-energised so that the lamp operates at full power. When the relay is energised, contacts c, d are closed so that part of the lamp current is shunted through a thyristor T in the circuit 4 and the lamp operates at reduced power. A potentiometer P enables the reduced power level to be adjusted. <IMAGE>

Title: System for mitigating consequences of loss of coolant accident at nuclear power station
IPC: G21C9/012
Filed: 1979-10-03
Abstract: The system according to the invention comprises a first room (1) which accommodates a reactor plant (3) and an active-type sprinkler means (10). As pressure rises in the first room (1) due to a release of steam from the lost coolant, most of the air contained in this first room (1) is driven out through holes (12) provided in walls (13) of the first room (1) in immediate proximity to a floor (18) of the first room (1), (14) wherefrom it proceeds to a second room (2) through channels (16) and a basin-type condenser (11) accommodated in the second room (2). The length of the channels (16) is selected so as to form a water seal in these channels (16) to prevent the back-flow of air from the second room (2) to the first room (1) and thus produce rarefaction in the first room (1). <IMAGE>

Title: Improvements in ploughs
IPC: A01B61/04
Filed: 1979-12-12
Abstract: A plough beam (1), whose forward end is pivoted to a plough frame so that the plough beam can swing upwardly when the ploughshare thereon encounters an obstruction, is provided with a bellcrank lever (20) at its rear end shown in Fig. 3. A spring is disposed in a tubular portion (2) of the beam (1) and acts on a carriage (34) to place a draw rod (16) under tension, the forward end of the latter being attached to the frame. Due to the location of the pivots (25 and 32) relative to the fulcrum (21) of the lever (20), the tension in the draw rod (16) is reduced as the plough beam swings up, despite the increasing compression of the spring. <IMAGE>
