Title: Throwaway syringe ampoule - with cannula holder retained in sleeve by tubular foil with tear-awat strip
Inventor: HERMANN EWALD ING GRAD
IPC: A61M5/34
Filed: 1979-01-11
Abstract: A throwaway syringe ampoule has the closed top anchored in a sleeve, made of an elastic plastomer such as polyethylene, polypropylene or PVC.

Title: Machine tool workpiece parameter indication method - uses scanning and electric signal feed of scanned value into indicator unit
Inventor: RENOWDEN JOHN STUART
IPC: G01B7/00
Filed: 1979-01-25
Abstract: The method is for indication of a function related to the individual size of workpieces in a machine tool. The stages involved are the probing of the workpiece parameter value the formation of an electrical signal from that value the storage of the signal the removal of the workpiece rom the machine for physical determination of the required size function. The electrical signal is then fed into an electrical indicator unit activated by a circuit until it indicates the size function as physically determined. The circuit and indicator are such that the probed parameter values of further workpieces produce size signals enabling correct size functions to be shown by the indicator.

Title: Chocking arrangement for varying-dia. aircraft external loads - has lugs spring-loaded towards load, held apart by load-released spring compressor
Inventor: HUETTER HORST
IPC: B64D1/06
Filed: 1979-09-20
Abstract: The chocking arrangement for varying sia. loads carried externally on aircraft utilises the principle of pressing lugs against the load surface. These lugs (19) are at the outer ends of coaxial pistons (17) with flexibly-jointed connecting rods (12) to a transverse bolt (13) through a central plunger (10). Downward movement of this plunger compresses stack of springs (23) tending to push the pistons closer together, until the bolt passes through the spring's line of action when the assembly is locked over-centre. Hooking-on the load lifts the plunger, releasing the springs to press the lugs against its surface.

Title: Water-raising pump system for delivering electricity - uses explosion of gas-air mixture to provide raising force
Inventor: EICKMANN BODO DR ING
IPC: F03B13/06
Filed: 1980-02-11
Abstract: The pump system is used to raise a body of water to a higher level so that it can be used to drive turbines delivering electrical energy as it is allowed to return to its initial level. The motive force for raising the water to the higher level is provided by an explosive gas/air mixture fed to a series of press vessels and with sequential ignition so that the vessels are emptied and the refilled with water in succession. A common riser pipe leads the water discharged from each vessel to a reservoir at a higher level, with the turbine incorporated in the return flow path. The water may be obtained from the sea or a lake with the explosion cycle controlled to give a constant high press inlet flow for the higher level reservoir, to provide an uninterrupted electricity supply. The system is rapidly brought into operation upon failure of the network supply.

Title: Inversion procedure in dual temp. gas laser - uses rapid hot gas cooling to achieve vibrational and translation etc. energy
Inventor: ALTMANN KONRAD DIPL PHYS DR
IPC: H01S3/0953
Filed: 1980-03-05
Abstract: A thermal imbalance is produced in a dynamic gas laser so that a certain degree of vibrational freedom exists in a molecular gas on the one hand and a freedom of rotation and translation on the other. A hot gas is rapidly cooled by mixing with a cold gas in a CO2 laser using a mixture of CO2 and N2. The chemical composition of the hot and cold gases can be the same or different and the same applies for the carrier gas. The mixing takes place close to the jets. The relaxation time coefficient, T, satisfies the condition Tm is much less than Tv, where Tv is the time constant for the oscillation relaxation. The mixing procedure also satisfies the condition Tm is much less than Te, where Te is the electronic excitation time constant. The method maintains translation and rotational energy as well as vibrational energy according to given formulae involving gas constants, temp. and oscillation temp.
