Title: Underground electric cable pipe - using inflatable elastic tube inside spiral reinforcement surrounded by cylindrical shuttering
IPC: E02F5/10
Filed: 1975-08-06
Abstract: The underground concrete pipe for electric cables is created by digging a rectangular trench. Circular spiral reinforcement is lowered into the trench together with a longitudinal spade plate. The reinforcement is surrounded by circular shuttering and an elastic tube placed within the spiral. The tube is inflated to the required internal diameter of the pipe and concrete poured between it and the shuttering. The shutters are removed when the concrete has set and the trench is back filled.

Title: Load sensitive brake control valve - with servo piston to maintain load resistance on valve element
IPC: B60T8/18
Filed: 1975-09-12
Abstract: The brake control valve regulates the wheel brake pressure w.r.t. the loading sensor setting on the suspension and the input brake pressure from the master brake cylinder. The valve operates with inlet and outlet parts linked by a double action piston. In order to ensure an even operation of the servo piston w.r.t. different input pressures a sliding piston is fitted to the main valve element shaft. The sliding piston is subjected to the input pressure and alters the setting of the operating spring of the valve to compensate for pressure changes.

Title: Hanging bracket for postal bin - has pair of inverted L=shape hooks on vertical base for catching flange of hanging bin
IPC: A47F5/00
Filed: 1976-06-30
Abstract: The bin-hanger deploys a double inverted wall-hook to support a bin with a deep square-returned external edge-flange and utilises rotation of the bin relative to the wall-hook to effect a suspension interlock which is augmented by gravity. The system may be used to support postal bins. The two hooks cantilever horizontally in plate-form from a wall-plate and at a specific vertical interval. The free ends of the hooks may return down through 120 deg. may be co-planar, and may also lie in a common plane with a doubly folded formation on the foot of the wall-plate. The bin is placed on the hanger by first tipping it so that the leading bin wall inclines towards the hooks.

Title: Methane-rich gas prepn. from waste materials, esp. household refuse - by gasification under pressure with oxygen and steam (NL 1.5.77)
IPC: C07C4/04
Filed: 1976-11-03
Abstract: Prodn. of methane-rish gas from waste materials esp. domestic refuse, after sorting and top. comminution, involves gasification with oxygen and steam under pressure. The hot prod. gas is treated to remove dust and used to generate steam, followed by sepn. of condensate and removal of acid components e.g. CO2H2S, and HCN. The steam generated is pref. superheated and under 6-8 bar pressure, and at least part is used in the gas generator. The gas is pref. cooled in the waste heat boiler to 290-300K, and then cooled to 223K for removal of CO2 and H2S by washing with organic solvent. The gas produced contains a high proportions of CH4, and is generated by a continuous process under pressure, which simplifies the purificn. process and allows the CH4 to be fed into the natural gas system. The process can be economically integrated with an air sepn. plant.

Title: Reproduction of ancient tapestries - by printing and heat-shrinking a bonded fabric to obtain uneven appearance
IPC: D06C23/04
Filed: 1977-05-17
Abstract: A base fabric with an uneven weave pattern resembling a repp is bonded with a thermoplastic synthetic material by localised application of a binder or glue, and printed with a coloured design before being submitted to heat shrinkage. A lumpy or blistered effect is achieved on the base fabric approaching the uneven appearance of ancient tapestry. Previous attempts to copy tapestry have lacked a sufficiently raised effect. The method reproduces an unevenness, or a raised effect, in addn. to the colours and design as near as possible to the original material.

Title: Plug for attaching objects to partition or wall - has split flange to grip opposite surface of partition
IPC: F16B13/08
Filed: 1977-05-23
Abstract: A method of fixing objects to relatively thin partitions or walls uses a plug (1) with a circular end flange (2). A circular boss (23) projects from the flange (2) and carries two parallel longitudinal ribs (3). Two split flanges (5, 6) have slots which allow them to slide over the ribs. The half flanges are loosely connected to the plug (1) by bolts. This allows the larger half flange (5) to be inclined at an angle to the plug axis so that it can be pushed through a hole in the partition. As the bolts a*e tightened, the half flanges are pressed against the inner surface of the partition and hold the plug firmly in place.
