Title: Improvements relating to frequency stabilising systems
Inventor: WILLIAMS RAYMOND ANTHONY
IPC: H04J3/06
Filed: 1964-11-18
Abstract: 1,081,012. Automatic control systems. FERRANTI Ltd. Nov. 17, 1965 [Nov. 18, 1964], No. 47038/64. Heading G3R. A digital data network includes a plurality of digital data centres such as A, B, C, interconnected by duplex data links Figs. 1 and 2 (not shown), each centre comprising a frequency standard 11 having an output frequency approximately equal to the output frequency of the standard at each other centre; a frequency changer 12 to which the output from standard 11 is applied together with a further input derived from an adder 21; and phase comparators 15 and 16 providing the outputs which are added algebraically in the adder 21. The centres are interconnected so that at each one centre, comparators 15 and 16 compare the output frequency of their associated frequency changer with the output frequency of the frequency changer of another station and produce outputs proportional to the difference between these frequencies; these outputs, via the adder 21, control the output frequency of the frequency changer 12. Thus because of the interconnection the system stabilizes with the output frequencies of the frequency changers 12A, 12B, and 12C, at the centres A, B, and C respectively, all equal to each other, and the operation of the system as a whole does not rely on the operation of a single centre. The frequency changer 12 may comprise an alternator having a stator to which the output from the frequency standard 11 is applied, and a rotor which provides the operating output frequency and which is driven by a D. C. motor whose speed is controlled by the signal from adder 12 Fig. 3 (not shown); the frequency changer may alternatively comprise a three phase variable capacitor associated with a D. C. motor driving a rotatable plate of the capacitor.

Abstract: 1447699 Excavator jib assemblies POCLAIN 1 Nov 1974 [22 Nov 1973] 47316/74 Heading E1F An excavator jib assembly having a variable geometry comprises a pre-boom 5a and a jib 7a rigidly joined by two connecting rods 31a, 32a, the rods being articulated to the pre-boom 5a about a common axis 30a and to the jib 7a about axes 16a and 17a. The jib 7a has a plurality of axes 16a to 20a so that to modify the geometry of the jib assembly from that shown in Fig. I it is necessary to dig the bucket 10a into the ground, release the connecting rod 31a from the axes 16a, and advance the excavator until the freed end of the connecting rod 31a can be articulated to the jib about axis 18a. The procedure may be repeated until the axis 20a is reached. In a further embodiment (Fig. 3) an adjustable stop (34a) is provided on the pre-boom 5a.

[Also in Division D1] A method of manufacturing tubes, e.g. contact cables which are distorted or squashed to close remote control circuits, by helically winding at least one tape 1 over a stationary mandrel 3 by contact of the wound tape with an endless travelling belt 4, the formed tube 13 axially rotating about the axis thereof being thereafter wound on a rotating bobbin 14 in superposed layers and after passing through a guiding frame 23 rotatable around the bobbin independently thereof, including the step of automatically and continuously adjusting the angular speed of the bobbin as the diameters of the superimposed layers increase so as to allow the ratio of the speeds of the guiding frame and belt to remain constant. As shown, the belt 4 is driven by an electric motor 11 which is connected by a speed adjuster 19 and chain drive 20 to a hollow shaft 15 mounting the bobbin 14. During rotation thereof, the bobbin pulls and winds the tube 13 which passes through the shaft 15 and a hollow shaft 15a, which rotates at a different speed, and then around pulleys 21 and a guiding carriage 22 mounted on a frame secured to the shaft 15a and freely mounted in relation to the shaft 15 and the drum 14; the carriage is driven longitudinally by a shaft 26 having helical threads and connected to shaft 15 by a chain drive 28. As the tube 13 winds on to the bobbin the frame 23 is caused to rotate freely, friction devices adjust. ing the tension of the tube and limiting the speed of the frame. The latter compensates for rotation applied to the tube during the formation thereof. The tube consists of a helically wound and tensioned inner tape 1, the turns of which are held in edge-to-edge relationship by an outer helically wound and tensioned adhesive tape 2.

[Also in Divisions F4 and G3] A mechanism for actuating one or more flue dampers (not shown) through wire ropes 26, 28 comprises a pivoted handle 24 maintained in any desired position by locking trunnion 40 pivotably secured to its end, and spring-loaded to fit into depression 46 in a locking plate 48. On release of the locking trunnion 40 by depression of locking lever 42 against the action of spring 52, manual adjustment of the handle and so the damper to a new desired position may be effected. Automatic closure of the damper in the event of a power or burner failure is effected through a pneumatic piston/ cylinder unit 54 to the piston 56 of which a slotted member 60 is attached. A pivot-pin 62 to which are attached links 64, 66 is slidable in the slot 60. On actuation of the unit 54, the slot 60 slides around the pin 62 till the latter contacts the lower end of the slot, further movement of piston 56 firstly releasing locking trunnion 40 from depression 46 through the action of link 66 and then pivoting the handle to its full closed position (Fig. 4, not shown). The piston/cylinder unit 54 may itself be pivotable about point 58, or alternatively it may be rigidly mounted in which case the slotted member 60 is pivoted to the piston 56.

A snap ring 168 is in groove 170. Retainer 172 has a tab 194 engaging recess 196 of nut 160 and a tubular portion 174 bears on its cylindrical surface 175. The nut cam surface has nine toothlike projections with steep and gradually sloping flat surfaces 182 and 184 connecting flat surfaces 183, 185 normal to the nut axis. Annular spring 180 has interior axially extending tabs 189 engaging grooves 198 and three arcuate arms 190 bent from its plane. When nut 160 is rotated so that they engage slope 182, they offer great resistance, but not in the other direction. The presence of a groove 200 between shoulder 171 and portion 174 indicates the locked condition of the connector because ring 164 is warped. Ring 164 is smaller axially than one of these grooves so that it can shift on shell 152 to engage opposite sides of this groove.
