Abstract: BRAKE DISC MOUNTING                     ABSTRACT OF THE DISCLOSURE            A brake disc mounting on a shaft in which a spacer is interposed between the disc and a pilot rib of the shaft to facilitate brake disc removal and reduce disc distortion effects.  There may be an opening adjacent the spacer which provides for displacement of a portion of the spacer to accommodate the shrinkage.  The spacer itself may provide for displacement caused by disc shrinkage.          The spacer may be of a softer material than said disc or be resiliently deformable.

Abstract: An apparatus for electrolytically processing aluminium material comprising rectifier means for supplying a pulse power to the electrodes, at least one of which is the aluminium material to be processed, and controller means for supplying a control signal to the rectifier means to enable the same to produce from a multi-phase AC power a pulse power balanced between the phase.  The electrodes are connected with each other by a by-pass circuit which is controlled such that the electrodes are short-circuited by the by-pass circuit during the quiescent time of the pulse power to enable the electric charge stored in the electrolytic bath to be discharged rapidly to prevent the trailed natural discharge through the electrolytic bath from interfering with the rise of the next pulse, thus preventing the deformation of the pulse waveform supplied to the electrodes.

Abstract: ABSTRACT OF THE DISCLOSURE             The present invention relates generally to security systems of the type which includes a central controller connected with a number remote stations.  Existing systems have a central controller for polling a number of remote transponders connected to the controller by telephone lines, but these prior systems typically have the capability of inter-rogating only a single alarm condition at each transponder site.  More complex systems are well within the state-of-the-art of today's digital communications technology, but a key limiting factor is cost, especially cost of the modem equipment.  The present invention overcomes these deficiencies of the prior art by providing an improved transponder system and method of use.  The transponder detects polling signal bursts of a particular frequency from the central controller, and counts the bursts to determine its turn for response.  Each response includes two sequential signal bursts of different frequencies, the durations of which define, with the frequency sequence, the status condition being transmitted.  Con-trol information is encoded into the lengths and spacings of the polling signal bursts, and is decoded by the transponder, to indicate transmission errors, transponder resetting commands, and remote control commands.  Means are also provided at the transponder for transmitting a special alarm code when electrical power is first applied to the transponder, thus indicating the possible substitution of an unauthorized transponder at a protected site.

The material is preferably made from poly-propylene and is produced from film which is roll-embossed and fibrillated, the roll-embossing temperature being sub-stantially lower than the conventional roll-embossing temperature.  In the case of polypropylene film this is within the range 60°C to 90°C, preferably about 80°C.  As a result, the fibrous material has a high proportion of clusters of from 2 to 5 unseparated incipient filaments. Baler twine made from the material is economical to produce and has improved physical characteristics especially good strength combined with good knot retention ability.

Abstract: ABSTRACT      Moulded bodies produced from a mixture of comminuted fibrous materials and a thermo-setting binder are provided with a protective and/or decorative coating during the mould-ing operation by placing a protective sheet or film, for example of paper over which a transparent protective synthetic resin layer is disposed.  The mixture is first cold moulded without the covering layer to form a preliminary blank or so-called pre-pressing which is then hot-moulded in two stages.  In the first stage the uncoated blank is compressed to a pre-determined volume greater than the desired volume of the finished body and after opening the mould and placing the covering layer over the pressing, the mould is closed and the coated blank is compressed in the second stage to its desired volume and cured, thereby bonding the protective layer to the body.  A moulding apparatus is disclosed comprising upper and lower heated mould parts movable respectively toward and away from each other and removable spacer means insertable between abut-ment members on the mould parts to alter the spacing between the mould parts between a first and a second hot moulding sta?e.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus provide for the elimination of any net DC component from the transmission of binary data sequentially in successive clocked bit cells of a transmission channel wherein logical first bit states, e.g., 0's, are normally transmitted as signal transitions relatively early in respective bit cells, preferably at cell edge, and logical second bit states, e.g., 1's, are normally transmitted as signal transitions relatively late in respective bit cells, preferably at mid-cell, and any transition relatively early in a bit cell following a transition relatively late in the next preceding bit cell is suppressed.  The onset of a sequence of second bit states following a first bit state that might introduce a DC component into the transmitted signal with normal transmission is detected by producing a first indicating signal, and in response to the first indicating signal, the state of a current bit and the state of the next succeeding bit,the transmission of signal transitions is modified to eliminate any DC component.  Preferably, the end of a sequence of second bit states that would introduce a DC component is detected by producing a second indicating signal utilized to modify the signal transitions at the end of a troublesome sequence, as by suppressing the transition corresponding to the last second bit state in such a sequence.
