Abstract: The invention relates to the field of chemistry, more specifically to multifunctional coupling agents which are used e.g. for synthesizing functionalized block copolymers. The aim of the invention is to provide coupling agents which react selectively through addition reactions and which contain one or more additional, activable functional groups. To this end, the invention provides multifunctional coupling agents with cyclic iminoester and iminoether groups of general formula (1), wherein X contains one or more additional, activable functional groups in particular. The invention also provides for a method for reacting carboxylic acid chlorides with aminoterephthalic acid to produce intermediate products which are then reacted further.

Title: Lightweight recoilless heavy projectile launcher - has pressure chamber between throttle plate and Laval nozzle
Inventor: BEDALL HANS
IPC: F41A1/08
Filed: 1973-06-19
Abstract: The recoilless launcher barrel for heavy projectiles has a high pressure chamber whose rear end is connected to a convergent/divergent Laval nozzle. The lightweight launching barrel is made from glass fibre reinforced plastics, and is intended as a disposable equipment. It imparts initial acceleration to the relatively heavy projectile whose propulsion unit is ignited after leaving the barrel. The high pressure chamber is arranged within the metal sleeve in the rear part of the barrel. This sleeve accommodates the propellant and ignition charges. The nozzle is separated from the charge by a grill plate and bursting disc. The closed end of the pressure chamber, which has pressure reducing channels separates the pressure chamber from the projectile base. This arrangement reduces the recoil forces. The proportion of weight of the metal high pressure sleeve is low.

Title: Prefabricated plastic pipe system for under floor heating - has two metal pipe headers for flow and return
Inventor: SCHAEFER GUENTER
IPC: F24D3/14
Filed: 1973-08-30
Abstract: Two metal headers are connected by a number of plastic pipes running between them. The assembly is prefabricated off site to suit the dimensions of each room and placed in position in one piece on the floor base before the floor finish is applied. The heat output can be adjusted to the room requirements by variation of the plastic pipe spacing between one side of the assembly and the other. Prefabrication in this way reduces site labout costs and reduces the number of pipe fixings needed. Plastics pipes cross-sectional area is smaller than header cross-sectional area.

Title: Luggage transportation trolley with braking system - pushing frame pivot as it is pushed or pulled releasing brakes
Inventor: MANSS AUGUST
IPC: B62B5/04
Filed: 1973-12-24
Abstract: The trolley for use at stations or airports etc, consists of a base frame and a vertical pushing frame. This consists of two curved bows connected by the handle. The brakes operate on the rear wheels and are operated by a brake rod on the pushing handle. This is interconnected to the curved bow frames which release the brakes as the pushing frame is pivoted. A modification overcomes the difficulty that operators tend to pivot the frame and apply the brakes while the trolley is moving. The pivot point for the bow frame is above the point at which the frame is held so that if the frame is pushed or pulled the brakes are automatically released. The bow frame is U shaped. The lower horizontal part of the bow fits onto the handle.
