Title: Lead seal made in two halves - has tongue and slot locking mechanism which is impossible to open without damage
Inventor: NIEDECKER HERBERT DIPL ING
IPC: G09F3/03
Filed: 1972-05-05
Abstract: The two halves of the seal have parallel bottom surfaces and sides and the other half has a tongue with a hook that engages in a slot in the inner half. The edges of the two halves (1, 2) of the seal are continuous around its front side and the tongue (9) and its retaining hook (11) are stamped out of the base of the outer half. The length of the tongue is pref. such that when the seal is closed it impinges on the opposite wall (16) and bends at the point (17) where the hook is stamped out. The bending of the tongue increases the locking effect and if the seal is opened the tongue breaks off. The tip of the tongue produces a mark in the opposite wall as a check that the seal has been closed correctly.

Patent DE-2348746-A1 (DE)
Title: Snap closing microswitch and adjustment method - operating tension can be quickly and accurately set
Inventor: BECK WALTER
IPC: H01H5/00
Filed: 1973-09-28
Abstract: To allow the on and off switching to be set at two specific pressures a diaphragm microswitch requires adjustment of the return spring and the position of the contacts. Using the proposed method of setting it is possible to use a microswitch with fixed contacts. A selection of return springs with a range of spring constants is required. The method of setting involves the use of a test spring with a known spring constant. The switch -off pressure is set by adjustment of the test spring and the switch-on pressure checked. The difference between this and the required switch-on pressure then defines the spring constant of the required spring. The appropriate spring from the selection is then exchanged for the test spring and the setting adjusted as required.

Title: Enzymatic determination of substances in whole blood - diluted with e.g. water and treated with protein-reacting substances
Inventor: RATHJE WERNER PROF DR
IPC: C12Q1/32
Filed: 1974-01-19
Abstract: In a procedure for the enzymatic determination of substances in blood without removing blood corpuscles or proteins, the blood is diluted with water or with solns. which do not react with the contents of the blood, then the diluted matl. is treated with substances which react with proteins (in an amt. less or greater than that required for complete reaction with the protein content of the blood) and/or heated to a temp. lower than the coagulation temp. of the blood proteins, the enzymatic determination being subsequently carried out by known procedures. The simple procedure avoids the need for tedious procedures to remove blood corpuscles and proteins.

Title: Waste polyurethane foam is burnt after melting - in separate chamber to reduce bulk and facilitate control
Inventor: RAFFENBERG HERMANN-JOSEF
IPC: F23G7/12

Title: Index page attachment for magazines - index tabs folded inwards during binding and trimming to prevent inadvertent removal
Inventor: ROEDIGER ALBERT
IPC: B42C1/10
Filed: 1974-05-17
Abstract: A method of incorporating index page inside a brochure, catalogue etc., so that the tab which projects from its edge can form an integral part of the index page, and not attached separately by adhesive, and so that the tab is not inadvertently cut off during trimming and binding, makes the width of the index page narrower than that of the signatures to be bound, and the tab is hinged, so that it can be bound with the signatures instead of being secured in the magazine after binding. Thus, with the tab folded over, binding and trimming operations are carried out, then afterwards the tabs extended in the normal indexing position.
