Title: Fairground machine pivoting load lifting and lowering mechanism - has accumulator connected to hydraulic ram and charged on lowering
Inventor: STENGEL WERNER DIPL ING
IPC: B66F13/00
Filed: 1976-08-26
Abstract: The mechanism lifts and lowers a load, which pivots about a fixed point under the action of a hydraulic ram. An accumulator is connected to the pressure side of the hydraulic ram, this being charged when the load is lowered, and at least partly discharged when it is lifted. A drive system, working in both directions, is connected between ram and accumulator. The accumulator can be of the piston type, and the drive can comprise a pump delivering in both directions, and driven by an electric motor. A stop valve can be fitted between pump and accumulator, shut when the motor is stopped.

Title: Dispenser for dropwise metering of viscous glue - uses static pressure to move adhesive into quick-acting proportioning valve
Inventor: ZIMMER ALBERT
IPC: B05C11/105
Filed: 1976-09-24
Abstract: The proportioner is for drop-wise dosage of fluid or viscous materials, esp. single component adhesive. The material (4) is pressed by static pressure from a storage vessel, within a container (6) which is subjected to static pressure, into the valve chamber (34) of a proportioning valve (24), and there maintained under pressure. A short-time opening of the valve allows the material to move via a pipe line to a drop dispenser (78), into a capillary conduit (80). An impulse-like pressurized air jet removes the drop from the capillary outlet (82), and blows it against a surface (108). The valve movement and the air jet are actuated via two pressurized air control valves (64, 102).

Title: Prepn. of glycero-phospho-choline ester(s) - by silylating glycero-phospho-choline and then acylating with an acid chloride
Inventor: LEKIM DAC DR
IPC: C07F9/10
Filed: 1976-10-20
Abstract: Prepn. of glycerophosphocholine esters of formula (I) or (II); (where R1 and R2 are 7-21C opt. unsatd. alkyl and/or aryl opt. substd.) from a 2- or 3-glycerophosphocholine cpd. comprises (i) adding a silylating agent pref. trimethyl chlorosilane to a suspension of natural or synthetic glycerophosphocholine in an organic solvent in the presence of an organic proton acceptor, and then (ii) reacting with an acid chloride of formula RCOCl (R = R1 or R2). (I) are used in the pharmaceutical industry; phosphahdyl cholines are one of the main components of the natural phospholipids of plant, animal and human tissue. Silylation gives an intermediate which is soluble in organic solvents. On addn. of an acylating agent and a proton acceptor, (I) can be obtd. directly and rapidly in high yields and in homogeneous phase. Previous methods using either free glycerophosphocholine or its Cd-adduct, both of which are insol. in the reaction medium have been slow as a result of the inhomogeneity.
