Title: Open-end yarn piecer
Inventor: BISCHOFBERGER JURG
IPC: D01H4/50
Filed: 1987-08-14
Abstract: A travelling piecing apparatus (72) is provided for piecing a rotor spinning machine having a plurality of spinning stations. Each station includes a rotor unit (10) package forming means (14) to form a package of yarn produced at the unit, a nip roll pair (12) for withdrawing yarn from the unit and feeding it to said package forming means (14), feed means (30) selectively operable to feed fibers to said unit for spinning into yarn and drive means operable to drive the rotor unit (10) at a selected operating speed and to drive the package forming means, nip roll pair and feed means at respective speeds each in a selected relationship to said operating speed. Withdrawal of yarn (18) after piecing with a fiber ring in the rotor is effected by re-engaging previously separated withdrawal rolls (52,54) on the rotor spinning machine. Feeding of the seed yarn and newly spun yarn pieced thereto can be effected while the spinning unit is operating at a predetermined constant speed, preferably at or near the selected normal operating speed for the spinning unit. A control unit (84) is provided in the travelling piercing device to define a predetermined time period during which the fibre ring is formed, the yarn fed back and the end rejoined to the fibre ring. At the expiry of the period withdrawal of seed yarn is commenced. By adjusting the backfeed of seed yarn relative to the predetermined time period, the duration of a "rest- period" is determined. During this rest period, the end of the seed yarn is in the rotor groove and twist is transferred from the seed yarn to fibers in the groove. By control of the rest period, twist transference to the fibers is controlled. <IMAGE>

Title: Restricted access television transmission system
Inventor: RIST BRUNO A
IPC: H04N7/16
Filed: 1987-08-26
Abstract: The invention resides in a Television Signal Transmission Security System which provides a higher degree of security then previously possible by utilizing encoding and decoding technology which effectively prevents pirating by amateurs or experimenters. The television signal transmitted is encoded by injecting one or more interfering carriers (24, 26) in specific frequency slots in close proximity to the video carrier (10). Interfering carriers (24, 26) can be injected either above or below the video carrier (10) between harmonics (41-44) of the horizontal frequencies. Combinations of interfering carriers (24, 26) provide coding techniques making the system virtually pirate proof. The interfering carrier (24, 26) is removed by very narrow band rejection filters (100-113) having a rejection band attenuation greater than about 40dB over bandwidth of up to 4000Hz and a 3db bandwidth of approximately 5kHz. The filters (100-113) are constructed using advanced technology to produce the quartz crystal bulk resonators or surface acoustic wave filters. Pre-compensation at the transmitter improves overall amplitude and phase response to provide a nearly perfect decoded picture.

Filed: 1987-12-30
Abstract: A game board presents a playing area which includes two endless pathways divided into sections along which the players move respective play elements representing trucks. The outer pathway represents a motorway whilst the inner represents a road and is divided into two lanes. The number of sections moved by each player is determined by throw of a dice. Some of the sections are designated load values which the players collect from a supply of load elements.   The two pathways are linked at intervals by crossover points, e.g. chevrons or islands, at which a player may move from one pathway to the other. A random direction selector (e.g. a spinner) determines the direction in which a player leaves the island. <P>Some of the sections are marked "fortune card", "weather report" and "MOT" and any player who lands on that particular section is required to select the appropriate chance card at random and obey its instruction. There are also squares marked "cash in load" and "cash or load" where a player can exchange his accumulated load values for money from a bank. A player can use the money to purchase property sites and services in order to extract a fee from other players who land upon the appropriate sections. <IMAGE>
