Title: Shotgun cartridge with thin flexible plastics sleeve - has pellets held in compact formation to reduce drag and improve accuracy
IPC: F42B7/04
Filed: 1974-09-12
Abstract: A shotgun cartridge has the pellets housed inside a fire flexible plastics sleeve which is afterwards sealed by thermo welding so as to hold the pellets in a tight, thin, cylindrical formation. The plastics material ensures a good, accurate flight with reduced air resistance, and ensuring that on impact, the bursting of the plastics give a close scatter of shot near the target, especially where the plastics sleeve is closed under vacuum. The thickness of the material can be selected to determined the scatter time. The use of plastics material reduces the cost of the cartridge.

Title: Construction of reinforced concrete basement in weak subsoil area - has beam and slab floor strutting walls apart
IPC: E02D17/04
Filed: 1974-10-25
Abstract: Reinforced concrete basements are constructed in areas of high water tables and weak plastic sub-soils by using ribbed or beam and slab floor acting as a prop. between opposed basement walls.

Title: Appts. making non woven decorative material - has adhesive coated grid of threads passed through flocking tunnel between electrodes
Inventor: ROELLINGER PHILIPPE
IPC: D06Q1/14
Filed: 1975-03-07
Abstract: The non-woven decorative material is used as curtains or wall covering.

Title: Portion distributor for food pastes - delivers constant vols. by star-shaped rollers
IPC: A21C5/00
Filed: 1975-07-07
Abstract: Portion distributor comprises a hopper fixed above a belt conveyor, two elongated, star-shaped rollers, rotating in opposite directions on parallel shafts, fit partially inside the semi-cylindrical seatings. Each of the rollers has four summits with curced surfaces in between. During the synchronous rotation of the rollers, the edges of the opposite summits practically touch each other at every quarter turn and receive the paste leaving the distribution conduit of the hopper. This mass of paste is cut off from the remainder as the edges come together, as the rollers turn, another portion of the paste will be detached by the coming together of the next pair of edges and so on. The vol. of paste thus transported does not under go any mixing but only a limited amount of deformation, which does not alter its characteristics. Appts. is simple because the same components which proportion the paste cut into portions which are constant and precise.

Title: Current limiter for battery chargers - uses operational amplifiers to prevent preset current-voltage ratio being exceeded
IPC: H02J7/00
Filed: 1975-10-09
Abstract: The current limiting circuit provides protection against excess load currents for lead acid battery chargers, and has a minimum number of components and the consequent risk of failure of such circuits.

Title: Liq. phase prodn. of aliphatic alcohol(s) - from carbon mon:oxide, hydrogen and acetylene over iron catalyst
Inventor: KAGAN J B
IPC: C07C29/36
Filed: 1977-06-30
Abstract: Prepn. of 3-20C aliphatic alcohols (I) consists of the treatment of CO, H2 and C2H2 in a liq. solvent with a catalyst at 170-220 degrees/20-200 atmos. Solvent is a fraction of satd. 10-18C aliphatic alcohols and/or 12-20C paraffin hydrocarbons. Catalyst contains 92-95% Wt. Fe3O4, 0.5-2 wt.% K2O or Na2O (alkaline promoter); and 3-7.5 wt.% V2O5, Al2O3, and SiO2 (as structural promoter). Process allows increased C2H2 concns. to be used, thus increasing the reaction rate and process space-time yield. A constant temp. may be maintained over the catalyst bed, and the accumulation of high m.pt. prods. on the catalyst is avoided. The thermal stability of the process is greater, and the catalyst has a longer life.
