Title: Method and installation for uninterrupted supply of alternating  current to a load
IPC: H02J9/06
Filed: 1972-11-20
Abstract: 1401488 No break A.C. supply systems COMPAGNIE GENERALE D'ELECTRONIQUE INDUSTRIELLE LEPAUTE 20 Nov 1972 [18 Nov 1971] 53469/72 Heading H2H A circuit for supplying uninterrupted A.C. to a load 1 comprises A.C. sources 2, 3 connectible to the load via inverse parallel connected thyristors 43, 44 and 45, 46, circuits 61-63 and 71-73 for monitoring the voltage between points A, B<SP>1</SP> and A, O<SP>1</SP> respectively, a circuit 81-83 for monitoring the voltage across the load and a logic circuit 5 for controlling the thyristors to connect one of the sources to the load if the monitor circuits detect that both sources are simultaneously disconnected from the load or to change the source if the load voltage remains lower than a predetermined voltage V for longer than a predetermined time. One of the sources 2, 3 may be a D.C. source connected to an inverter whilst the other source is the supply network. Each monitor circuit includes a pair of Zener diodes and a resistor, and the voltages between the points A, B<SP>1</SP>, A, C<SP>1</SP> and A, D<SP>1</SP> are fed to respective first operational amplifiers in the circuit 5. Further operational amplifiers connected to each of the first operational amplifiers compare the voltages V B <SP>1</SP>-V A , V C <SP>1</SP>-V A , and V D <SP>1</SP>-V A  with a reference voltage V to provide logical 1 or 0 signals to a system of NAND gates. A delay circuit, connected to the portion of the logic circuit which monitors the voltage across the load, establishes the predetermined time. If the logic circuit detects that both sources are disconnected from the load, a 20 kHz. signal from an oscillator is gated to a transistor amplifier circuit to enable firing of the thyristors associated with the previously redundant source. Similarly if the load voltage is less than the reference voltage for a period of time greater than the predetermined time established by the delay circuit, the thyristors associated with the previously redundant source will be fired.

Title: Articles handling apparatus
IPC: F41A9/30
Filed: 1972-11-22
Abstract: 1368170 A multi-barrel gun GENERAL ELECTRIC CO 22 Nov 1972 [23 Nov 1971] 53879/72 Heading F3C A gun has a number of stationary barrels 10, Fig. 1, disposed in an annular row and has a rotating feed ring 14 with a number of partitions 16 forming a number of projectile receiving compartments 18. Four push arms 20 are cam controlled to sequentially push a selected projectile from its respective compartment through a transport mechanism into alignment with a respective chamber. The ring 14 is supplied from a feeder which is fed either from a conveyer or directly from a linkless feed drum exit unit. The gun, ring 14 and feeder and conveyer or unit are geared together for positive control of the projectiles fed to the gun. If misfiring occurs a projectile remains in the feed ring 14 and this is detected by a sensing device. The projectile is detected after it has passed the last firing position, this being at a sensing zone 26, Fig. 2. An adjustment is made in a drive train between a hand-off sprocket 22 and a feed sprocket 24 to allow the sprocket 22 to continue rotating while the feed sprocket 24 pauses for the space of one pitch and the feeding action then continues to supply projectiles to the ring 14. In an embodiment a sensing linkage 38, Fig. 3 (not shown), is moved to adjust differential gearing 34 and introduce a pause to the feed sprocket 24. In modifications differential gearing is adjusted by an escapement wheel 44, Fig. 5 (not shown), and by centripetal displacement of a sector 372, Fig. 6 (not shown) of a Geneva device wheel assembly 356, Fig. 7 (not shown).

Title: Fiber Molding Pellets
Inventor: HUMPHREY FREDERICK HAROLD
IPC: B29B9/14
Filed: 1966-12-05
Abstract: 1,159,579. Reinforced mouldings. F. H. HUMPHREY. 5 Dec., 1966 [6 Dec., 1965], No. 54424/66. Heading B5A. [Also in Division D1] A pellet for use in moulding reinforced plastics articles comprises fibres which have been elastically flexed and a binder which restrains the fibres from unflexing and which loses its binding effect during the moulding so that the fibres unflex and distribute themselves in random directions. The pellets may be formed by twisting two bundles of glass filaments together, applying a binder before or after the twisting, setting the binder-for example using an oven-and cutting the twisted strand into pellets. Alternatively, untwisted glass filaments may be cut into short lengths which are subsequently bent double and restrained from unbending by a binder. The binder may be polyethylene which melts during the moulding, or a polyester or polystyrene resin which dissolves in liquid unsaturated polyester resin from which the article is moulded. The moulding may be carried out by pouring the resin over the pellets in a mould from which air may have been evacuated, by dropping the pellets into the resin in a mould, or by mixing the pellets with a powdered plastic. Pipe fittings, valve bodies, pump parts or machine components may be cast. Pipes may be made by feeding pellets using pneumatic, screw, or vibrating conveyer systems to the inside of a rotating mould in which liquid resin has previously been deposited. In a specific example, a hollow sphere was formed by adding 80 parts by weight of liquid unsaturated polyester resin which had been catalysed and 20 parts by weight of the pellets to a spherical mould which was rotated about two axes by a gimbal arrangement.

Patent GB-1367287-A (GB)
Title: Magnetic device for cylindrical domains
IPC: G11C19/08
Filed: 1971-12-03
Abstract: 1367287 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 3 Dec 1971 [31 Dec 1970] 56158/71 Heading H3B In a moving domain device of the kind where domains are propagated in a magnetic sheet by the interaction of a rotating in-plane magnetic field and magnetic overlays on the sheet, the magnetic bias field normal to the sheet necessary in such devices to produce stable domains is altered at certain points of the sheet by juxtaposed magnetic overlays so that at those points a domain may be split or collapsed. In Fig. 2A a domain 14 is being propagated along permalloy T and I overlays in the direction of arrow 20 by a rotating field H, and a bias field is applied normal to the sheet. A domain collapser is formed by permalloy bars 12A, 12B on opposite sides of the sheet, and in this Figure the bars overlap. The actual positioning of the two bars is governed by their thickness and that of the sheet, and the magnitude of the propagation field. As the field rotates the domain 14 moves as shown in Figs. 2B and 2C; in the latter Figure the domain is captured by the collapser, and initially expands because at that moment the field between the collapser elements 12A and 12B opposes the bias field. As the propagation field continues to rotate the collapser field enhances the bias field and the domain is destroyed. In Fig. 5A another collapser is shown, using overlays on one side only of the sheet. This embodiment has an L-shaped overlay one arm 38A of which is so long that the domain 14 will not propagate along it. Thus when the propagation field rotates so that were the arm 38A shorter the domain would pass along it the domain is destroyed by the reversal of the magnetization of the left hand end of arm 38A, Figs. 5B-5D (not shown). Figs. 3A-3D show a domain splitter, the overlays shown in solid lines being on top of the sheet and those shown dashed being beneath it. The domain 14 is initially propagated along the L bar 12A, i.e. towards the top of each Figure. It becomes trapped between the elements 12A, 12B as in the case of the collapser of Figs. 2A-2C, but the elements are chosen so that their fields are insufficient to destroy the domain. As the propagating field rotates, the domain is attracted to the right by T bar 24 and to the left by T bar 26 and it elongates before finally splitting into two domains as in Fig. 3D. Figs. 4A-4D show a splitter using overlays on one surface only. The domain 14 of Fig. 4A has travelled towards the top of the Figure under the influence of the rotating field; as the field continues to rotate the domain spreads as in Fig. 4B. In Fig. 4C the field position is such that the pole induced at point 32A pinches the domain, and the domain is also stretched towards point 3 of the overlay 32. In Fig. 4D the field has rotated further, and the induced poles at 32B and 34 continue the pinching. The combined pinching and stretching cause the domain to split.
