Title: Checking of repeat accuracy of endless patterns - uses optical mirror system to superimpose adjacent pattern images for observation
Inventor: SINDERMANN WOLFGANG DR
IPC: G01B11/14
Filed: 1977-02-02
Abstract: A method for checking the repeat accuracy in an endless pattern employs an optical device to superimpose adjacent pattern repeats on one another. The endless pattern having a repeat length is placed on a light table comprising a frosted glass screen illuminated by a number of lamps. Further lamps provide overhead illumination. The pattern repeat lines are reflected by a pair of mirrors and the image is viewed by an observer after further reflection in the silvered surfaces of a prism. by slight movement of the eye, the observer can determine the accuracy of the pattern repeats, whose positions may be measured by means of scales mounted on the sides of the apparatus.

Title: Caravan and awning connector - is flexible plastics section with co-extruded protrusions forming runners
Inventor: ITZIGEHL HANS-JOACHIM
IPC: E04H15/04
Filed: 1977-02-23
Abstract: Soft flexible plastics section has a short non-flexible hard part which acts as a runner for easy sliding along adjoining metal parts and is used as the connecting piece between awnings and caravans. The hard slide runners which can be made of a non-homogenous material which contains soft and hard plastics parts is in the form of protrusions which does not impair the flexibility of the total section member. The hard parts can be made from parts of the non-homogenous material which is continuously co-extruded with the remaining flexible section. Alternatively, the hard parts forming the runners can be formed by subsequently separating a continuous strip of hard plastics which has been formed by coextrusion. This plastics section made of hard and soft materials allows the runners to be inserted in the metal rails in hot or cold weather.

Title: Choke for DC=DC pulsed power converter - has air gap slot at one end with faces diverging at angle selected for linear inductance-current relationship
Inventor: TENDULKAR GAUTAM
IPC: H02M3/28
Filed: 1978-11-06
Abstract: Appts. may be used in a converter employing a choke as an energy store from which load current can flow during the period when the primary current from the dc power supply is off. The demands on the choke at high and low load differ requiring a higher inductance at low load in order to avoid discontinuous primary current. A suitable choke can be made by introducing a graded air gap (Sp). It is preferrable for the faces of the gap to diverge with an angle (alpha) which is greater than zero degrees, and for the faces to be flat. Such a graded gap gives a suitably linear relationship between inductance and current. There are thus no sudden changes in time constant to adversely affect control stability.
