Abstract: ABSTRACT OF THE DISCLOSURE          The specification describes a brushless self-starting D.C. motor which includes a rotor having a permanent magnet, a stator winding the direction of current flow through which is controllable by and responsive to the angular position of the rotor by means of a controllable electronic servo-element, in series with the stator winding at a D . C . source.  A magnetic field-dependent component is subject to the rotor magnetic field to determine the angular position of the rotor and a change in the field-dependent component is effective to provide the control signal for the servo-element.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to an apparatus for mixing or atomizing fluids without moving parts.  The apparatus includes, in combination, a hollow tube having a substantially cylin-drical inner wall.  A core member, which has an outer surface, is located in the tube substantially coaxial with but slightly spaced from the inner wall.  The core member has, extending inwardly from its surface, at least one non-intersecting helical channel extending substantially continuously around the length of the core member.  A channel-forming means is secured to the core member and extends round the length of the core member in substantially continuous contact with the outer surface of the core member.  The channel-forming means is also in frictional contact with the inner wall, such that the core member and the channel-forming means are removably secured in the hollow member essentially only by the frictional contact and are removable as an integral unit from the hollow tube.  The channel-forming means comprises one layer of at least one non-intersecting helical winding opposite to the first helical direction, the direction of each winding in the layer being opposite to the direction of each channel in the core member.

Abstract: Abstract of the Disclosure Esters and amides from 4-hydroxy-and 4-amino-polyalkyl-piperidines and hydroxybenzylmalonic acids substituted at the central carbon atom with an organic residue, preferably alkyl-, esteralkyl- or phosphonoalkyl-groups, are excellent stabilisers for organic polymers, especially for polyolefins.  They protect the polymers, as well against light degradation as against thermo-oxidative degradation. The compounds can be prepared by hydroxybenzylation of the corresponding derivatives of substituted malonic acids. Bis-malonic acid derivatives may be obtained from the mono-malonics by reaction with formaldehyde.

Abstract: APPARATUS FOR WORD SYNCHRONIZATION IN AN OPTICAL COMMUNICATION SYSTEM            Abstract of the Disclosure An optical communication system is disclosed in which a bipolar signal of the type transmitted in digital transmission systems is converted into a unipolar binary signal for transmission over an optical transmission medium.          The three levels of the bipolar signal are converted into three pairs of bits in the binary signal.  One pair of bits is not utilized in the conversion and is therefore labeled as a forbidden word.  Synchronization is achieved at the receiving location for the purpose of decoding by detecting the presence of the forbidden word in the binary signal and in response to this detection an energizing pulse is produced.  This energizing pulse drives a clock circuit which in turn drives a decoding apparatus utilized to translate the binary signal back into the bipolar signal.          As a result of this type of word synchronization, individual errors introduced into the binary signal do not result in a framing error.

Abstract: CLOSED TORUS TIRE               Abstract of the Disclosure A closed torus tire in which the cord or wire reinforcement ply, or plies, surround the inflation chamber which can retain pressure without being mounted on a wheel.  The reinforcement ply is continuous cir-cumferentially of the tire and axially in the crown and sidewalls.  The circumferential ply edges are lap-spliced in the inner wheel-engaging part, rather than being folded around bead cores.  The tire is made without use of a building core of any kind, thus avoid-ing the cost and difficulty of removing such core from the completed tire.  The tire is made by wrapping the reinforcement ply, or plies, about a cylindrical drum to form a sleeve.  An inner liner is then wrapped about the sleeve, a reversal of normal tire building practice. One circumferential edge of the sleeve is then moved outward and axially over the remaining sleeve, beyond the other, unmoved edge.  The one edge is then moved inward and axially under the other edge to form the lapped splice.     The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the Pull nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawings and the following detailed description.

Abstract: ABSTRACT OF THE DISCLOSURE         Control of an active three-axis multiple-wheel attitude control system is provided with a bias momentum to achieve stiffness about the pitch axis.  With this stiffness, the system overcomes the inherent inability of a zero momentum system employing the sun as its yaw reference to be provided with this yaw reference during the periods encompassing satellite high noon and midnight (i.e., approximate coalignment of the sun line and the local vertical).  The satellite attitude is normally maintained by angular momentum exchange developed by three or more reaction wheels positioned on the satellite.  The control mechanism is arranged to provide net angular momentum in the pitch axis wheels to achieve the momentum bias or stiffness along the pitch axis, whereas the time average of the angular momentum about the roll and yaw axes is substantially zero.

Abstract: A B S T R A C T          An air structure comprises a double-skin wall construction having an outer skin that is substantially transparent to short wave solar radiation but relatively opaque to long wave heat radiation and an inner skin.  Radiation converter elements, preferably in the form of black plastic diaphragms linking the inner and outer skins and effective to absorb solar radiation and to convert the same to heat energy are disposed in the inter-skin space.          The structure is self-erecting on exposure to solar radiation, and may advantageously be combined with a heat store that emits heat and maintains the structure erected under conditions of reduced solar radiation availability.  The structure may be free floating or may be anchored to the ground to form, for instance, a greenhouse or other enclosure.
