Title: Sheet turner for a small offset printing machine
Inventor: JESCHKE HERR WILLI
IPC: B65H5/08
Filed: 1986-01-28
Abstract: Two adjacent printing units 1,2 of a small offset printing machine for first-form and perfector printing are connected by a chain system provided with gripper bridges, said chain system conveying the at least one-side printed sheet from one printing unit to the other. The chain system consists of two endless conveyor chains, running parallel to each other and being connected with each other by the gripper bridges. The lower part 5 as well as the upper part 4 of the chain system is wound like a "Möbius band", so that the sheet transported e.g. by the lower part is turned about its longitudinal axis while being transported. This sheet turner makes it possible to use similar printing plates, since the sheet is not tumbled - as was convention so far - but turned during the turning process. The fact that both parts of the chain system run wound through 180 DEG C, so that after one revolution the control means of the gripper bridges always come to lie on the same side, is particularly advantageous and guarantees a simple and inexpensive design of the control devices. <IMAGE>

Title: Control of RDS data by supervisory transmissions
Inventor: PARNALL SIMON JOHN
IPC: H04H20/34
Filed: 1987-08-24
Abstract: In a radio data system a transmitter broadcasts its own first service, identified by its service number, and transmits digital codes as well as programme material. The codes include other Network (ON) codes which provide information about other networks e.g. receivable local stations, and include the service numbers of the other networks to which they pertain. A second transmitter station receiving such ON codes can respond to those which have its particular service number by updating its own RDS information which includes codes pertaining to itself and by responding to those with other service numbers to assemble and transmit on ON codes which relay the received codes, including the service numbers. This allows ON information to be reconstructed off the air, and allow simplification of fixed inter-transmitter links.

Title: Over write capable magnetooptical recording medium
Inventor: SATO MATSATOSHI
IPC: G11B11/105
Filed: 1989-08-02
Abstract: An over write capable recording medium comprised a substrate and a magnetic layer. The magnetic layer is stacked on the substrate and includes first and second layers each having a perpendicular magnetic anisotropy. When a high-level laser beam radiates the medium, the magnetization of said second layer is reversed and a bit information of magnetization is recorded in the first layer under the influence of the magnetization of the second layer. When a low-level laser beam radiates the medium, a bit information of magnetization is recorded in the first layer under the influence of the second layer. This over write capable magnetooptical recording medium exhibits a high C/N ratio without decreasing recording sensitivity. The method is facilitated by providing the two layers wherein the Curie temperature of the first layer is less than that of the second layer whilst the coercivity of the first layer exceeds that of the second. <IMAGE>

Patent GB-2242446-A (GB)
Title: Positioning pre-twisted cable elements
Inventor: GOSLING CYRIL HENRY
IPC: D07B7/02
Filed: 1990-03-20
Abstract: Running elements H, of non-circular cross-section, have a preparatory S-Z twist, and are to be positioned for incorporation into an S-Z twist cable. Each element passes through a rotatable sensor S in a rotatable disc BC. The twist in an element H rotates a sensor S, and the movement of sensor pointer E is sensed (e.g. by electrical, mechanical or optical means) to control rotation of disc BC. Such rotation bends element H until pointer E is centralised. An apex of element H always points towards the axis of disc BC. A number of discs BC may be used in sequence, and the sensors may be on a disc separate from disc BC (Figure 2). For circular elements H, a computer may replace the sensors to obtain required element bending. <IMAGE>

Title: Pyrolytically forming an oxide coating on a hot glass substrate by pre-mixing reactants
Inventor: TERNEU ROBERT
IPC: C03C17/00
Filed: 1990-06-19
Abstract: A method of pyrolytically forming a silicon oxide coating on a hot glass substrate as it travels past a coating chamber comprises contacting the substrate with silane-containing coating precursor material in the presence of oxygen characterised in that the silane-containing coating precursor material is in the vapour phase and it and gaseous oxygen are intimately mixed before they enter the coating chamber to contact the substrate. Silane eg SiH4 as coating precursor material may be conveyed towards the coating chamber in vapour phase in a substantially inert carrier gas stream and oxygen introduced into the silane-containing carrier gas stream before it enters the coating chamber. The coating operation may take place within a coating chamber within a float chamber in which the glass is formed into a ribbon. The coating chamber may be defined by the ribbon path and a downwardly opening hood, and it may be aspirated around substantially the whole of its periphery. As illustrated in Fig. 4 the silane-coating precursor material is supplied into a carrier gas stream at a first venturi 9 and further downstream a second venturi 11 is provided for the introduction of oxygen, for example as a constituent of air. Constrictions along the supply line 7 ensure intimate mixing of the oxygen and the entrained coating precursor material in the carrier gas stream. The coating reagents are then fed to a flow control block 13 having an exit slot 14 which extends across the major part of the width of the hood 5 past which the hot glass travels. The substrate preferably reaches the coating chamber with a temperature of at least 400 DEG C. Preferably the gases are brought into contact with an upper face of a hot float glass substrate while the glass is within a float chamber in which it is manufactured. <IMAGE>
