Patent GB-950655-A (GB)
Abstract: 950,655. Dynamo-electric machines; motors with commutation by semi-conductor devices; control of motors. COOK ELECTRIC CO. May 23, 1961 [June 6, 1960], No. 18610/61. Headings H2A, H2F and H2J. [Also in Division H3] A motor, Fig. 2, having a set of permanent magnet poles 30a ... 30f and a set of electromagnet poles 36a ... 36f arranged in concentric circles is characterized in that one set of poles is provided with asymmetrical projections 52 which project towards the other set, whereby the rotating set comes to rest out of alignment with the stationary set so that the motor will be self starting. Referring to Figs. 1, 2, each electromagnet stator poles 36a ... 36f of a 6-pole motor has two energizing windings 40, 42, which are energized alternately to produce the N and S poles. In an alternative construction, Fig. 3 (not shown), the projections are provided on the rotor poles. In order to provide the alternate energization of the electromagnet poles, the coils are connected in the collector circuits of two transistors connected as a reciprocally coupled trigger circuit (see Division H3) coils 42a, 42c, 42e and 40b, 40d, 40f in one collector circuit and coils 40a 1 , 40c 1 , 40e and 42b 1 , 42d 1 , 42f in the other. The circuits may be either astable to give continuous running, or bi-stable to give a stepping action. In a further arrangement, Fig. 9, for stepwise action, the coils are energized by connecting either of the above sets to the supply by means of a relay 282 with a change over contact 268. Alternatively, Fig. 13, the poles may be given a magnetic bias and the polarity may be reversed by energizing a single set of coils. The bias may be provided by means of a suitably magnetized ring 354 mounted at the end of the motor in contact with the cores 44 of the single coil windings. In an embodiment employing a commutator for switching the current to the coils, Figs. 10, 11, the two sets of coils are connected to fixed commutator segments formed by studs 308 and a brush 306 mounted on the rotor shaft is held by the action of spring 324 in contact with the commutator segments 308 and slip ring 316. Direction of rotation of the motor may be reversed by mounting the projections 376, Fig. 16, on a rotatable ring 380 so that they may be moved from the left-hand to the right-hand side of the poles.

Title: Individual section machine for manufacturing glass containers
Inventor: PETERSON GEORGE THOMAS
IPC: G05B19/07
Filed: 1995-05-24
Abstract: An I.S machine system has a number of mechanisms 10, 12, 14 which are driven by inverter drives and a number of machine and section mechanisms which are driven by profiled motion actuators which are controlled by repetitive sequencers associated with the actuators. These repetitive sequencers are synchronised by taking the reference signal from a master clock 37 which supplies the reference signal to the inverters and converting it to a once/cut sync signal, 35, for the machine mechanisms operated by profiled motion actuators and to a once/cycle sync signal, 33, for the section mechanisms and controllers. <IMAGE>

Title: Method for establishing communication links between non-stationary units
Inventor: STACKMAN JAMES THOMAS
IPC: H04B7/185
Filed: 1995-06-12
Abstract: A method for establishing communication links (210, 216) between communications units such as satellites that are travelling in different determinable directions, e.g. in counter-rotating orbits (218, 220) includes calculating communication link boundary corridors (202, 204, 206, 208) within which communication between the two units is possible, generating a schedule informing the units when and how to establish and maintain a link, transmitting the schedule to the units, and establishing the link according to the schedule. Enabling such links between counter-orbiting satellites makes it unnecessary to route data packets over the poles. <IMAGE>

Title: Method and apparatus for correcting deformation of annular elements.
Inventor: OKITA SHIGERU
IPC: C21D1/00
Filed: 1995-12-20
Abstract: In a method and an apparatus for correcting a hardening deformation of an annular element made out of steel, during the cooling stage of hardening, the annular element which still has an austenitic structure is subjected to working on either the outside or inside diameter, (e.g. by being pressed into a mould) with the degree of working being 0.05 - 1.0% if and 0.5 - 3.0% if the working is on the inside diameter. Thus the deformation that develops in annular steel elements due to heat treatments is effectively corrected to yield completely round, strain-free or deformation-free annular elements. <IMAGE>

Title: Cover and frame assembly
Inventor: THOMPSON KEITH
IPC: E02D29/14
Filed: 1996-07-26
Abstract: A cover and frame assembly comprises a frame 10 adapted to be received in the ground, and a cover 39 engageable with the frame to selectively prevent or allow access to an opening beneath the frame. The cover is formed in two parts 40a, 40b, and releasably secured together, the frame and cover being configured so as to allow the cover to be slid over the opening into the frame. Limited articulative movement is permitted between the two parts of the cover, which not only enables the cover to locate in the frame a "non-rock" manner, but also facilitates removal of the cover from the frame. When the cover is lifted by one of the keyways 46, the corner seats along line 69 tilt the cover and allow it to be slid linearly. Then one of the guide members 57 on the underside of the cover members comes into play by engaging the side of the frame and allowing the cover to be slid further as required.
