Title: X-ray film cassette
Inventor: SCHMIDT MANFRED
IPC: G03B42/04
Filed: 1983-08-04
Abstract: A first intensifying screen 15 is secured to a flexible magnetic plate 14 provided on a top part 9 of a cassette, while a second intensifying screen 18 is rigidly secured to a counterfoil 17 which is flexibly attached to a cassette bottom part 1 by means of securing elements 16. The parts 1 and 9 of the cassette are interconnected by a hinge 13 so that they may be opened and closed to permit an X-ray film (not shown) to be inserted between the intensifying screens 15 and 18. Each of the securing elements 16 comprises a foil strip 16a secured to the cassette bottom part 1 by an adhesive strip 16b and secured to the counterfoil 17 by an adhesive strip 16c, these two adhesive strips being mutually offset. The assembly of the counterfoil 17 and the intensifying screen 18 can thus move relative to the cassette bottom part 1 in directions both parallel and perpendicular to a base wall 2 of that cassette part. To increase the freedom of movement the strips may be weakened e.g. by providing oblique, arcuate or V- shaped cuts. <IMAGE>

Abstract: In a method of and apparatus for forming a knitted fabric without knitting needles, new loops are formed in succession by blowing required loop lengths of a yarn (13) with air through nozzles (8) into primary loops in the preceding course. The yarn-feeding nozzles (8) blow the loop lengths through the primary loops (22) and holes (3A) e.g. in a rotating cylinder 2, ejector air nozzles (9) blow the new loops back through the holes when the course has been lowered sufficiently as by rollers 19, and loop-raising nozzles raise the new loops and align them around the small holes (3). An embodiment for forming rib fabric has inner and outer rotating rings with respective rings of holes and the nozzles for inserting the yarn oscillate between the rings. <IMAGE>
Patent GB-2146291-A (GB)
Title: Rotary printing press
Inventor: CLIBBON MICHAEL EDWARD
IPC: B41F5/24
Filed: 1983-09-14
Abstract: A rotary printing press eg for multi-colour use omits the customary gearing for ensuring print registration between the plate cylinder (2) and the impression cylinder (1). Instead a microprocessor controlled control unit (20) for separate motors (9 and 6) driving the plate cylinder (2) and impression cylinder (1) maintains print registration during the operation of the press. This allows the plate cylinders to be rapidly brought onto impression because the control unit (20) will maintain registration despite separation of the plate cylinder (2) from the impression cylinder (1), and also allows each of the various plate cylinders (2) of a multi-colour press to be brought onto impression simultaneously when appropriate plate cylinder-moving means (14, 16) are provided. An optional facility provides for the printing plate to occupy only a portion of the cylindrical surface of the plate cylinder and for the angular velocity of the plate cylinder to be varied when there is no contact between the plate and copy medium at the printing nip (for the purpose of changing repeat length between successive print regions). <IMAGE>

Title: A method of carrying out a radio propagation survey
Inventor: BERRY JOHN BURNETT
IPC: G01R29/00
Filed: 1984-10-26
Abstract: A method of carrying out a radio propagation survey in which a site (10) FIG 1 which may be an industrial site, such as a power station, or an urban area, is divided into a plurality of elemental areas (12) of a size greater than twenty times the wavelength of the carrier frequency of a test signal transmitted by a base station (14). An operator equipped with a receiver (18) having a communications probability indicator (22) (Figures 2 and 3 (not shown)) proceeds from one elemental area to the next, either on foot or in a vehicle, monitoring a particular characteristic of the transmitted signal and the number of occurrences of that characteristic within a predetermined sampling period in each elemental area, thereby determining the quality of reception of that characteristic. This characteristic may be either the carrier strength or SINAD (the ratio of the [signal plus noise plus distortion] to [noise plus distortion]). In order to conduct a survey for two-way radio communication the power output of the base station is adjusted to equal that of the weakest transmitter to be used in the radio system. <IMAGE>
