Patent DE-2431250-A1 (DE)
Title: Halogen lamp contg. tungsten bis-(pi-cyclopentadienyl) halide - as convenient and immediate source of tungsten halide
Inventor: BARTHA LASZLO DR
IPC: H01K1/50
Filed: 1974-06-28
Abstract: A halogen cpd. (I) of formula C10H10WXn (in which X is Cl, Br and/or I; n is 2 or 4) or a mixt. of these cpds. is/are used as halogen additive for the filler gas of an incandescent lamp. (I) can be introduced into the gas space of the lamp in solid form, esp. as a constituent fo a film, or in the form of a soln., from which the solvent (e.g. liq. SO2, CHCl3 etc.) is evaporated before the lamp is filled. When the lamp is first switched on, (I) decomposes into W halide and other useful or inert decompsn. prods. The use of (I) thus eliminates the time lag in the formation of W halide, which occurs when a halogen is added, and avoids direct addn. of W halides, which are generally hydroscopic and unstable in air. The high mol. wt. of (I) facilitates accurate dosing. (I) (in which X is Cl, Br or I and n = 2) or adducts with 2 HCl or 2 HBr are stable in air for several weeks, are involatile and decompose at 250 degrees C without melting.

Title: Device for automatic insertion of cores in moulds - also pushes boxless mould out of mould making machine
Inventor: POPOW ALEXEJ I
IPC: B22C9/10
Filed: 1974-09-06
Abstract: A device for inserting cores in boxless moulds, consisting of a frame carrying a core holder with a through hole and a driving mechanism for moving the frame in a direction perpendicular to the joint line on moulds being made in an adjacent moulding machine.

Title: Omnidirectional microwave aerial has vertical polygonal reflector - at centre of circle of coherent horn radiators each facing one side
Inventor: THIELEN HERBERT DIPL PHYS
IPC: H01Q21/20
Filed: 1974-09-20
Abstract: The omnidirectional microwave aerial consists of a central polygonal reflector (1) with primary horn radiators (3) forming a circle around it. Each horn radiator is directed towards one reflecting side of the polygon so that the whole reflector reflects radiation over a 360 deg. angle in the horizontal plane. The axis of the polygonal reflector is vertical and its reflecting sides may either be vertical or taper towards its base. The advantage of the antenna lies in its being able to generate both a 360 deg. radiation pattern or a sector pattern (by not using some of the radiators).

Title: Recording support for data in form of projections or recesses - with protective coating on data storage side
Inventor: BOERNER MANFRED DR RER NAT
IPC: G11B7/24056
Filed: 1976-04-29
Abstract: Recording support for data in the form of relief-like projections and/or recesses, e.g. video disc, is covered by a protective coating on the data storage side. The coating is pref. bonded to the support only at the edges with gas-tigh joints, and in the cavities between support and coating is a gaseous medium, pref. dry air, or between support and coating is a layer of dye covering the whole surface of the support.
