Patent CH-638277-A5 (CH)
Title: Oscillating-armature pump
Inventor: TOYODA AKIRA
IPC: F04B17/04
Filed: 1978-12-05
Abstract: The prestressing forces of a restoring spring (10) and an auxiliary spring (9) of the oscillating-armature pump keep in equilibrium an oscillating armature (1) which is in pressure contact with a piston (6). That point of the electromagnetic coil (21) at which the magnetic force generated is zero is at a distance lb from that point of the oscillating armature (1) at which the magnetic force is likewise zero. The distance between the upper end of a magnetic pole (4) and the lower end of the oscillating armature (1) is la. The ratio la/lb must be greater than 0.1 and less than 1. This arrangement makes it possible to keep the discharge pressure of the pump in a stable range even if the voltage varies. The oscillating-armature pump, while of simple construction, makes it possible to stabilise, without using additional components, the discharge pressure in the case of voltage fluctuations of the electrical supply. <IMAGE>

Title: Transition metal catalysts, process for their preparation and their use
Inventor: WHITE JOHN F
IPC: C07C67/03
Filed: 1976-11-26
Abstract: A catalyst with a transition metal immobilised on a support is prepared by reaction of a hydroxylated support with a transition metal alcoholate of formula  M(OR)nQm. The symbols are defined in claim 1. The support is heated between 100 DEG  and 300 DEG C with the transition metal alcoholate in excess in relation to the available surface hydroxyl groups, in an inert hydrocarbon and in the presence of water, to perform a reaction of condensation of the transition metal alcoholate or of its oligomer with the surface hydroxyl groups. The catalysts contain 3 to 60 % by weight of a transition metal present on and bonded to the support matrix by oxygen bridges so that the transition metal atoms are bonded to one another by oxygen bridges. The catalysts are particularly useful in the preparation of carboxylic acid esters.

Title: Printed circuits and printed cable forms
IPC: H05K3/40
Filed: 1969-06-09
Granted: 1971-03-26
Abstract: A conductive material layer which can be chemically etched is laminated with at least one film of insulant. This film is perforated right through in a specified pattern and at specified zones. One surface of the metal foil is coated with an etch resistant adhesive thick enough to provide protection against the etching medium. This adhesive surface is brought against the perforated insulator film under such conditions that it forms a laminate. Given areas of the surface of the metal still exposed are coated with etch resist and that part of the metal not so coated is removed by chemical etching. The exposed adhesive is then removed to allow access to the metal through the holes in the film insulant. It is of uniform thickness on the metal surface. The insulator material may be flexible and the conductor layer of electrolytic copper. A polyester with additives is pref. used as adhesive.
