Title: Improvements relating to electrical supply systems
Inventor: SAUNDERSON DAVID MERVYN
IPC: H02J7/26
Filed: 1955-10-14
Abstract: 804,712. Alternators; automatic voltage control systems. STONE & CO. (DEPTFORD), Ltd., J. Oct. 4, 1956 [Oct. 14, 1955], No. 29321/65. Classes 35 and 38 (4). In an automatic voltage control system for a dynamo-electric generator in which the field excitation is derived by rectifying an A.C. supply which is controlled by a saturable reactor, the reactor is connected in parallel with the excitation rectifier in series with a common impedance. The alternator 1 supplies a D.C. load 2, 3 over a main rectifier 4 and excites its field 5 over a second rectifier 6. Assuming contacts 26 to be open, the power windings 14 of the self-saturating reactor 8 are linked in parallel with the rectifier 6 by a frequency compensating choke 20 and the parallel combination is energized by being connected in series with an impetance 18, 19 across the output of the alternator. The reactor 8 has a constant current reference winding 11 (in series with a barretter 13), a current compounding winding 15, and a D.C. voltage control winding . The flux due to winding 9 normally slightly exceeds that of the reference winding 11 so that any increase in D.C. output voltage increases the saturation of the reactor 8 thereby decreasing the current through the field rectifier 6 and so correcting the voltage. A transformer 21 provides transient feed-back from the field circuit to improve stability. The alternator 1 also has a compounding field winding 7 carrying the D.C. load current. To assist build-up at starting, the no-volt relay 24, which actuates isolating contacts 23 to prevent reverse current when the generator is stationary, also actuates contacts 26 to connect the field rectifier 6 directly across the alternator. An over-voltage relay 27 can open contacts 29 to interrupt the field excitation. Instead of an alternator a D.C. generator with tapped windings or auxiliary A.C. windings, or with a separate A.C. exciter may be used. Specification 804,711 is referred to.

Abstract: 1437350 Rotary feeders NATIONAL RESEARCH DEVELOPMENT CORP 7 June 1973 [22 June 1972] 29348/72 Heading B8A [Also in Division E1] A device, forming part of a tunnelling shield, for conveying excavated spoil from a pressurized region behind a tunnelling bulkhead 5 comprises a multi-compartment rotary member 1 in sealed engagement with a cylindrical or frusto-conical chamber 4 which has an inlet port 7 positioned to one side of the axis of rotation of the member 1 and open to the pressurized region and a discharge port 10 open to a position outside the region, each compartment being arranged to pass the inlet and discharge ports in turn to receive and discharge spoil, but not to be open to both at the same time, each part of the compartment assuming an angle to the horizontal in excess of that at which the spool to be removed slides, when in the vicinity of the discharge port. The axis of the rotor 1 may be perpendicular to that of the tunnelling shield, Fig. 1; the walls 2 separating the compartments extend radially and carry trailing walls 12 which prevent the compartments overfilling and preventing spoil jamming between the rotor and the edges of the ports. Alternatively, Fig. 7, a rotor 22 with helical blades 47 rotates about an axis parallel to that of the tunnel in a cylindrical chamber 21 formed between bulkhead plate 26 and a back plate 27, inlet and outlet ports 31, (43), Fig. 9 (not shown), being cut-out sectors of the plates 26, 27 respectively. A plate 39 in hopper 32 keeps spoil away from the top edge of inlet port 31 to prevent it from overfilling the compartments or jamming the rotor.

Title: Improvements relating to electrical control apparatus for transfer and other machines
Inventor: DALMAN FREDERICK NARBOROUGH
IPC: B65G43/00
Filed: 1956-09-27
Abstract: 871,471. Machine-tool details. DONOVAN ELECTRICAL CO. Ltd. Dec. 24, 1957 [Sept. 27, 1956; July 20, 1957], Nos. 29495/56 and 23047/57. Class 83 (3). [Also in Groups XXIII and XXV] In a milling, tapping, drilling and grinding transfer machine, in which a workpiece is carried from one machining or working station to another by chain, slat or roller conveyer or by trucks or supports moving on rails, a separate standard electrical control panel is provided for each machine tool. In the apparatus shown, only some of the stations are operative. At each even-numbered station, there is a milling machine having a suds pump and a fluidoperated feed for the cutter slide controlled by solenoid valves. The fluid-pressure rating of the hydraulic apparatus will usually be identical for each machine tool. The electrical relays and contactors for each machine tool are identical, being chosen according to the highest current rating required for any of the machine tools, and are mounted on a standard removable panel. The non-standard components for each machine tool, such as overload switches and fuses, are mounted on a separate panel which may be fixed or movable. All the panels are mounted in a control cabinet having a series of doors, but all the panels for a particular machine are not necessarily mounted behind one door. For instance, behind door D10 the standardized components for the milling machine 2LH are mounted on a standard panel MH and the non-standard components are mounted on a panel marked " FIXED." The detachable panel MH has two sets of contacts, one at its top, and one at its bottom, edge. The lower contacts are mounted in a block 109, Fig. 6, and are connected by swinging bars 105 to a corresponding series of contacts 111 (marked 2LH in Fig. 1) leading to the milling machine. The bars 105 are swung upwardly and pressed home to make connection. For quickly releasing the panels, such as MH, from the control cabinet structure 113, Fig. 7, bolts 115 are provided to each of which is attached a slotted plate having a cam groove 119 engaging a pin 121 on the bolt. When the plate has been slid upwardly it can be rotated to lie along the length of the bolt and so be withdrawn through the hole in the panel.

In a rotary pressure-loaded fluid-pump, or motor, of the internally-meshing gear type a rotatable externally-toothed gear 11 meshes with an internally-toothed gear 12 that is capable of moving orbitally about the axis of the gear 11 without rotating, the gear 12 being pivotally connected to one end of a hollow shaft 27 whose other end is pivotally connected to a ring 30 that is fixed to the casing 4 of the pump or motor whereas the gear 11 is attached to one end of a driving, or power-output, shaft 3. The pivotal connection at each end of the shaft 27 is effected by a plurality of balls 35 or 36 that are lodged in spaces between arcuate axially-orientated teeth 32 or 33, which are formed on the shaft, and matching teeth 31 or 34 that are formed on the gear 12 or the ring 34, respectively. The balls in each group thereof are connected to each other by either a wire ring 37, or 38, or a cage (not shown). The gears 11, 12 are situated between wear-plates 13, 14 that are positively coupled to the gear 12 by pins 15, the plate 13 being subject to axial thrust produced by an annular piston 16 due to pressure communicated to the rear end thereof from the high-pressure side of the pump, or motor, through a plurality of channels 17 so as to effect sealing of the working spaces between the gears. The number of teeth on the gear 12 is greater than that of the teeth on the gear 11. An outlet channel 9 for fluid is sequentially connected to the working spaces by passages 18, 19, 24, a plurality of radial slots 22 in the casing and a further plurality of radial slots 26 in the wear-plate 14, a similar provision being made for an inlet channel 10. The arrangement of passages associated with the channels 9, 10 is similar to that disclosed in Specification 1, 102, 997.
