Title: Cornering stabilisers for car - consist of air flaps to provide counter thrust on outside of curve
IPC: B62D37/02
Filed: 1978-09-07
Abstract: The sides of the vehicle are provided with air flaps (8) which pivot about vertical axes from their leading edges.

Title: Potted plants aligning and transporting appts - has container with sloping sides and movable plate actuated by ram
Inventor: TOERNSTROEM INGVAR
IPC: A01G9/10
Filed: 1979-04-12
Abstract: The device is for aligning and transporting long objects such as plants. The plants (3) fall one after the other into a container (7), whose width corresponds at least to the length of the plants including the root so that a plant can lie on the bottom of the container. The container bottom is formed by an inclined section (9) and an inclined and pivotable flap (10) which can be so pivoted away from the floor section (9) that a slot is formed.

Title: Blood flow measurement system - uses heated surface temp. variations utilising periodic heating timing frequency to control measurement amplifier
Inventor: STICK CARSTEN DR
IPC: G01N25/18
Filed: 1980-02-12
Abstract: The device for contactless surface temp. flow measurement is esp. for human and animal skin and organ blood flow measurement. The appts. forms delay-free transport measurement without damaging the measurement object or affecting the measurement parameter. The measurement is substantially unaffected by ambient condition variations. The surface being investigated is heated by thermal radiation and the resulting temp. change is measured. The heating may be performed periodically. The measurement signal is amplified using a frequency selective or lock-in amplifier. The heating source time frequency serves as a reference for the amplifier. An alternative approach is to cool the surface. A two-dimensional representation can be derived from the output of an opto-mechanical scanning system.

Title: Liquid phase epitaxy of garnet film on pairs of substrates - sepd. by lead oxide powder applied before growth to minimise bridging
Inventor: GOODRIDGE JAN HENRY
IPC: C30B19/06
Filed: 1980-04-16
Abstract: In liquid phase epitaxial growth of a garnet film on pair(s) of substrate, the substrates of each pair are sepd. by a material contg. PbO, which is applied as powder before epitaxy in such an amt. that there is no marked penetration of the melt in which the films grow between the substrates but sufficient to reduce the stresses on the substrates. The films are used in the prodn. of magnetic bubble domain elements. The process allows several films to be grown simultaneously with minimal bridging problems. It is extremely simple and cheap.
