Title: Electromagnetic relay with armature resetting leaf spring - has two differently prestressed shanks formed by leaf spring splitting, one for contacting and another for armature resetting
Inventor: AIGNER GEORG
IPC: H01H50/56
Filed: 1976-06-16
Abstract: The leaf spring (1) for the armature resetting engages the contact actuating element of the electromagnetic relay. The spring is split in two differently preset shanks (4, 5) in relation to the contact actuating element (8). The less prestressed shank (4) serves for contact making, while the more heavily prestressed spring (5) is used for armature resetting. Preferably the two shanks of the leaf spring are split over the entire length outside the clamping position. The shanks may have different cross sections, and the contacting shank may be prestressed in opposite sense to the resetting shanks. In such instance the shanks are mounted with a clearance in recess of the actuating element.

Title: Flame reaction burner - with burner tube entering tubular combustion chamber with steps of increasing diameter, used to produce hydrogen bromide
Inventor: BRACHEL HELMUT VON DIPL ING DR
IPC: F23C3/00
Filed: 1977-08-27
Abstract: Flame reactions are carried out in a device in which two gaseous reactants complete an exothermic reaction with the formation of a flame after premixing and passing through a burner tube in a combustion chamber. The combustion chamber is tubular and its cross-section is stepped up from the burner tube mouth downstream. This eliminates any mixing of gases in the flame with already cooled-down combustion gases. The flame burns in a laminar fashion and the flow velocity can be varied without affecting the stability of the flame front. Used in reaction of gaseous bromine with hydrogen to form hydrogen bromide.

Title: Chrome-tanning of leather - by chroming hides in tanning vessel and controlled heating in separate heating compartment
Inventor: MUELLER LOTHAR DR RER NAT
IPC: C14C3/06
Filed: 1978-07-14
Abstract: Leather mfr. by Cr tanning takes place in two separate steps, pref. continuously. In the first step, the hides are chromed in a stationary tanning vessel.
