Title: Auxiliary drive motor for vehicles - has eccentric spring mass systems resonated by short duration electric impulses
Inventor: POPESCU RAUL-FLORIAN DIPL ING
IPC: F03G3/00
Filed: 1977-10-04
Abstract: The motor has a wheel with radial arms constructed as hollow cylinder. Their axes are tangential to a central hub. Each arm contains a piston rod with two pistons at opposite ends. A winding energised through a control circuit in the hub moves the pistons against a spring. Because of the eccentricity of the arms this movement produces rotation. After a brief interval the energising currents are broken. The initial movement produces resonance in the spring mass systems in the arms and this maintains the motion. After a further interval a fresh electric impulse can be applied to keep up the cycle of events.

Title: Membrane mfr. for ultrafiltration, reversed osmosis, etc. - by embedding parallel micro:filaments in membrane material and removing by solvents
Inventor: STEMME REINER DR
IPC: B01D67/00
Filed: 1977-11-14
Abstract: Organic or inorganic microfilaments having to a great extent the same diameter, are embedded in material for the formation of membrane bodies for ultrafiltration and reversed osmosis. After the formation, the microfilaments are dissolved out, leaving behind open, pore channels with smooth walls. Before or during the embedding process, the microfilaments are aligned largely parallel to each other. The preferred alignment is imparted to the microfilaments during growth by external forces such as electrical or magnetic fields, or gravitational or inertial forces. Process provides a membrane with a wide range of applications from ultrafiltration to desalination, having uniform pores at high density in resistant membrane material, at costs of production which, taking into consideration the technical advantages, makes possible an expansion of its applications, together with improved performance in present uses.

Title: Ethylene glycol prodn. - from formaldehyde and a gas contg. carbon mon:oxide and hydrogen
Inventor: SUZUKI SHIGETO
IPC: C07C51/10
Filed: 1978-03-04
Abstract: The prodn. of ethylene glycol involves an initial stage (1) in which formaldehyde is contacted with a gas contg. CO and H2, in the presence of HF, so that CO is removed from the gas and (di)glycolic acid is produced. This acid reacts, in stage (2), with ethylene glycol and/or diethylene glycol, to give the corresp. glycolates. In stage (3) the residual CO and HD are extracted from the gas from stage (1) to give a gas with high H2 content which is contacted, in stage (4), with the glycolate(s), giving (di)ethylene glycol, a part of which is recycled to stage (2) to maintain a molar excess of glycol during the esterification. This process gives high yields of ethylene glycol.

Patent DE-2846955-A1 (DE)
Inventor: BECHTIGER CHARLES DIPL ING
IPC: H01H43/10
Filed: 1978-10-27
Abstract: An auxiliary contact block (1) which can plugged onto a contactor (2) and driven thereby and whose movable auxiliary contact piece (94) is switched with a time delay with respect to the movement of the contactor by means of a time-delay device. In this arrangement, a spring (5) is tensioned by the attracting contactor (2) by means of an operating member (8) and effects the advance of a toothed segment (3) whose movement is delayed by an escapement mechanism (71, 72). The toothed segment (3) drives the auxiliary contact piece (94) via a lever (6). At the same time, the spring (4) is tensioned. It effects the return, likewise delayed, of the toothed segment (3) when the contactor (2) drops and the spring (5) is thereby relieved. The difference in the spring forces is decisive during advance, that is to say during attraction of the contactor, for the force acting on the toothed segment and thus for the delay time. When the contactor drops, the advancing spring (5) is immediately relieved, so that during return only the return spring (4) acts on the toothed segment (3) and determines the delay time. The delay times during advance and during return can therefore be precisely and reliably determined by simple selection of the spring forces within wide limits even for very short times. Since it is possible to manage with small spring forces, the time delay device is not susceptible to wear. <IMAGE>
