Title: Method of and apparatus for coding and decoding PAL colour television signals
IPC: H04N11/16
Filed: 1980-02-19
Abstract: A PAL coder operates to cause spectrum folding of a luminance input signal Y by multiplying twice the colour subcarrier (44) and adding (42), the resultant being comb filtered (F12) to select frequencies which are multiples of the line frequency. The chrominance signals U, V are combined (48) into U + V and U - V on alternate lines and are then modulated onto subcarrier, the resultant being filtered in a comb filter (F22) to select frequencies which are odd integral multiples of half the line frequency. The two signals are then added. The comb filters mentioned can in an alternative be based on 313 or 625 line delays. Prefiltering of the Y, U and V signals can be combined with the main comb filtering. The resultant circuitry can be arranged to minimise the use of delays, and uses analogue signals throughout. A converse decoder filters then spectrum folds the luminance component, and filters and multiplies by subcarrier to derive the chrominance. Once a television signal has been encoded by use of the encoder subsequent decoding and recoding produces no theoretical impairment into the signal. <IMAGE>

Title: Improvements in or relating to nuclear magnetic resonance systems
IPC: G01R33/54
Filed: 1980-07-09
Abstract: The invention concerns the production of gradient fields for nuclear magnetic resonance apparatus particularly imaging apparatus. It has been earlier proposed that samples of the resonance signal be taken at intervals such that the field gradient integrals in each such interval are the same. This sampling is at unequal time intervals. It is now proposed to provide the gradient fields in discrete pulses with spaces in between at which samples S0-S5 can be taken. It is then straightforward to make the pulses of equal field integral or to provide extra small pulse 25 in one or both orthogonal gradients if the field integral should need adjusting before the next sample. <IMAGE>

In this way, the radial shield acts as a heat sink. <IMAGE>
Patent GB-2072643-A (GB)
Title: Aqueous H2O2 bleach compositions
IPC: C01B15/037
Filed: 1981-03-27
Abstract: Hydrogen peroxide-containing aqueous alkaline bleach having acceptable peroxide stability can be obtained by employing ethanol, in conjunction with amino compounds substituted by acetate or methylene phosphonates and hydroxyalkyl diphosphonates, especially ethylene (diamino tetramethylene phosphonate,) particularly with a polyhydroxy carboxylate, preferably gluconate, or an amino acetate. The liquid bleach can contain a small proportion of a surfactant. Under alkaline conditions, it is particularly difficult to prevent the hydrogen peroxide decomposing excessively rapidly during storage, but the addition of an alkaline additive minimises any change in the pH of washing solutions obtained by dissolution of generally bleach free washing compositions containing anionic surfactants.

Title: Assemblies of an ic module and carrier
IPC: B42D15/10
Filed: 1981-12-08
Abstract: A carrier element for an IC module (integrated circuit) comprising leads which are connected at one end with the corresponding terminals of the module and at the other end have a contact surface. The ends of the leads running into the contact surfaces extend unsupported beyond the edge of the carrier so that they can be bent into the desired position according to the intended purpose of the carrier element. When the leads are bent around the carrier plane towards the back surface of the module and united by using a castable material in a casting the result is a compact carrier element well adapted to the dimensions of the IC module. For the incorporation of the carrier element according to the invention into an identification card the free ends of the leads can be directed through corresponding recesses in the cover film of the card. During lamination of the layers of the identification card the ends of the leads are bent onto the cover film and thus pressed into the film material.

Abstract: Filled packets (18) are assembled in successive lateral rows with their leading ends (45) presented to respective pairs of grippers (72) on successive carriers (58) extending between the radial slides (57) of a packet feed wheel (49). Stepping of the wheel (49) causes the successive packet rows to be offered by their ends (45) into respective rows of M-shaped slits (114) in a card (112) carried around a card feed drum (110) whereupon fingers press onto folded-over packet ends (45) of the row to press the middle of the corresponding tongues (115) (and the packet end portions thereon) behind respective lips (116) defined by the M-shaped slits (114), to ensure that the packets (18) are securely retained. The card drum (110) is stepped in synchronism with the wheel (49) until the card (112) is full, when the drum performs a sufficient rotation to feed the filled card to a discharge station (D) and bring into place the next card (112). <IMAGE>
