Patent GB-2098807-A (GB)
Title: Method of making circuit elements in a film
IPC: H05K3/10
Filed: 1981-05-16
Abstract: A circuit element, such as a conductive track or a resistor, upon selected portions of a substrate 10 of an electrical circuit assembly, is provided by selectively heating parts of a coating 12 of a composition, the heating causing the circuit element, thereby formed from the coating, also to adhere to the substrate; the composition including a glass frit; or the circuit element being formed by dissociation of a suitable compound of the composition. The heating is caused by selectively irradiating the appropriate coating parts with electromagnetic radiation 14, by causing relative movement between the radiation source and the substrate, the arrangement being such that the radiation is incident instantaneously only upon a portion of the substrate, the incident radiation possibly comprising a laser beam. Subsequently, the non-irradiated coating parts selectively are removed. <IMAGE>

Title: A device for measuring the flow velocity of gases and liquids
Inventor: SCHAFER DR WOLFGANG
IPC: G01P5/12
Filed: 1982-07-09
Abstract: For measuring the flow velocity of gases and liquids using temperature-sensitive electrical resistors and a control circuit, the servo amplifier is built up of electronic components (5, 6) of which the current consumption is negligibly low in relation to the heating current, whilst the dimensions of the bridge circuit (1, 2, 3, 4) are such that the current which does not flow through the heated resistor is also negligibly low in relation to the heating current. The heating current flowing through the temperature sensitive resistor 1 corresponds substantially to the current supplied and is a measure of the flow velocity. The output signal fed to a monitor circuit is thus a current instead of a voltage. A resistor 3 provides compensation for changes in the ambient temperature. <IMAGE>
Patent GB-2132057-A (GB)
Title: Electro-optical image correction
Inventor: GROVES PHILIP RANGECROFT
IPC: H04N5/14
Filed: 1982-09-09
Abstract: To correct errors in the image on a pick-up tube caused e.g. by the geometry of the tube and deflection yoke, the value of a parameter is monitored at a number of nominally identical elements in the image e.g. of a test card, and a correction signal is derived therefrom. The difference between the observed and ideal signal is derived for each element by comparators, and the digital difference signals are converted to analogue for successive pairs of adjacent elements to allow interpolation. Each converter receives an analogue reference scaling signal, the two reference signals varying in antiphase at half the frequency of the monitored elements. The summed analogue outputs from the converters are stored as interpolated connection signals. <IMAGE>

Title: Fabric softening detergent
Inventor: RAMACHANDRAN PALLASSANA N
IPC: C11D17/00
Filed: 1983-04-14
Abstract: A particulate synthetic organic fabric softening detergent composition product of improved appearance and/or flowability is made by mixing together 10 to 60% of detergent composition particles having finely divided bentonite powder adhered to external surfaces thereof and 90 to 40% of similar such detergent composition particles devoid of such bentonite powder on the surfaces thereof. When the detergent composition particles, preferably spray dried, are white and the bentonite is off-colour the described product appears whiter than does a "control" wherein the same total proportion of bentonite is agglomerated onto the surfaces of all the detergent particles. Also, when the bentonite-surfaced particles are higher in content of tacky detergent than the non-bentonite-surfaced particles, which increased detergent content may be obtained by spraying aqueous detergent solution onto the particles before agglomeration with bentonite powder, the flow properties of the product are improved, compared to a product containing the same total proportion of the detergent evenly distributed throughout all the particles. The bentonite particles are adhered to the detergent composition particles with the aid of an aqueous spray, preferably of a dilute sodium silicate solution, and the agglomerate resulting may be used directly as a detergent composition or may be blended with detergent composition particles not having bentonite on the surfaces thereof.

Title: Conversion of alkanes to unsaturated aldehydes
Inventor: KHOOBIAR SARGIS
IPC: C07C45/37
Filed: 1983-04-14
Abstract: Alkanes, particularly propane and isobutane, are converted to unsaturated aldehydes, particularly acrolein and methacrolein, in an integrated two-step process wherein the alkane is dehydrogenated in a first step to the corresponding olefin, hydrogen, and by-products and the reaction effluent is passed directly into a second step where the olefin is oxidized to the corresponding unsaturated aldehyde without significant oxidation of the hydrogen and by-products. Some of the by-products of the first stage reactions, or the hydrogen, may be removed from the reaction effluent before it is passed to the second step. The aldehydes and by-products of the oxidation may be separated and the unreacted olefin and alkane recycled to the first step. Alternatively, the effluent from the second step may be used as feed to a further oxidation step for conversion of the unsaturated aldehyde to the corresponding unsaturated acid.

Title: Fuze safety mechanism
Inventor: NYGARDS OLOF
IPC: F42C15/31
Filed: 1983-04-29
Abstract: The present invention relates to a safety device comprising a housing (1) and a movable rotor member (2) which in a safe position is locked in said housing but when released is arranged to be moved during which movement a primer charge (6) is brought by the rotor member (2) from a safe position at the side of an "eye" (7) to an armed position in line with the "eye". An initiating electric igniter (11) for the primer charge (6) is cooperating with or comprises a penetrating small body (12) which could be shot or pushed away. The primer charge (6) is arranged in the rotor member (2) behind a barrier (16) preventing the initiation of the charge for (6). When the penetrating small body (12) is shot in the armed position it penetrates the barrier (16) and the primer charge (6) is initiated. The rotor member (2) comprises a protecting tongue (18) which in the safe position is aligned with the "eye" (7) so that if the initiating igniter (11) is activated in the safe position (accidental ignition) then the penetrating small body (2) is prevented from reaching the "eye" (7) at the same time as the protecting tongue (18) is deformed or bent by the body (12). By this deformation or dislocation the protecting tongue (18) comes into engagement with a stop member (20) which prevents the rotor member movement to commence or continue. In this way, the rotor member (2) is prevented from bringing the primer charge (6) into the armed position in line with the "eye" (7). <IMAGE>
