Title: Wideband rod antenna with constant impedance - has conductive counterweight or base plate and antenna rod section with cylindrical conductor of specified length
Inventor: BLASS JUDD
IPC: H01Q9/30
Filed: 1976-09-17
Abstract: The impedance of the antenna remains constant over a high frequency range comprising more than an octave. It consists of a conductive counterweight, or a base plate (18) and a rod antenna section (12) with a cylindrical conductor whose length is less than a quarter-wavelength at the lowest frequency in the given range. The rod antenna section is mounted in a plane transverse to the counterweight (18). One end (12a) of the rod section, nearest to the counterweight, is spaced from the latter by a wavelength fraction at the lowest frequency. The assembly contains a specified coaxial cable (16) and wideband devices (22) between the inner and outer conductor of the coaxial cable and the end (12a) of the antenna section.

Title: Melt adhesive copolymer contg. phenol and/or ter:phenol - with thermoplastic polymer giving ameliorated creep strength, useful for adhesive tape mfr.
Inventor: VITEK ROBERT DIPL ING
IPC: C09J123/28
Filed: 1976-10-28
Abstract: Melt adhesive consists of a copolymer of (a) 6 (0.01-3) wt. % phenol and/or terphenol with (b) >=1 polymer such as a butadiene-styrene copolymer, isoprene polymer, natural rubber, chlorobutyl rubber and/or C2H4-C3H6 copolymer. Polymer (b) may be crosslinked, esp. by O-, S-, N-, urea-, urethane- or -CH2-bridges between the polymer chains. The adhesives can be used for making adhesive tapes, e.g. for packaging industry. Copolymerisation with (a) increases degree of crosslinking and improves creep-strength, e.g. to >10 min. The use of terphenol as (a) also increases adhesiveness of the melt adhesive. The use of crosslinked (b) having a low degree of crosslinking increases the adhesive properties of the melt adhesive. On the other hand, creep-strength increases with a high degree of crosslinking.

Title: MOS memory regeneration circuit - is supplied with regeneration voltage from generator coupled to logic unit
Inventor: FISHER EDWIN P
IPC: G11C11/4074
Filed: 1976-12-01
Abstract: A voltage supply circuit is designed to generate the necessary periodic voltage for regeneration of a dynamic MOS memory circuit. The output of a signal regeneration oscillator is transmitted to a drive circuit over an address counter. The drive is coupled to the memory over rectifier and filter stages. A supply voltage module provides +12 and +5 necessary for the MOS memories. The negative 5V supply for the regeneration process is generated separately and operates together with the regeneration logic.

The amt. of (III) used is 0.01-0.5 wt.% (on I) compared with 0.5-10 wt.% previously.
Patent DE-2657797-A1 (DE)
Inventor: BRUNNER HEINRICH
IPC: E04G27/00
Filed: 1976-12-21
Abstract: For floor structures, in particular podiums, platforms or stairways, the invention provides a dismantleable, screw-free and pin-free load-bearing construction. The load-bearing construction is assembled from structural elements (1) which are arranged in rows, are rectangular in outline and have in each case two intersecting diagonal struts (2). At the point of intersection, the struts are releasably engaged with respect to each other. In the corners, the struts merge into connecting members (3, 4, 5). The connecting members are shaped such that they can be releasably connected to the connecting members of neighbouring structural elements. Connection can be effected by links (10) which can be pushed over the connecting members (3, 4, 5). <IMAGE>

Patent DE-2708875-A1 (DE)
Inventor: KLEIN JUN EDE
IPC: G01D5/56
Filed: 1977-03-01
Abstract: A magnet armature (MA) to which the load to be measured is applied is arranged in the air gap of an electromagnet (Mp) which generates a compensating lifting force. The magnetic field strength in the air gap, and the zero position of the armature are determined with the aid of a magneto-optic scanning device. The latter has a light source (L), a polarizer (P1), a magneto-optic element (M), effecting a rotation of the plane of polarization by means of the Faraday effect, on the surface of the electromagnet (Mp) averted from the magnet armature (Ma), a second magneto-optic element (S1) on the side of the air gap of the electromagnet (Mp) as field-strength probe, a third magneto-optic element (S2) on the air-gap side of the magnet armature (Ma) as zero-position probe, two analysers (P2, P3) and two photoreceivers (E1, E2). The output signals of the two photoreceivers (E1, E2) serve for controlling a stable current amplitude of a pulsed current source for the electromagnet (Mp) and for controlling the pulse duty factor thereof in such a way that the magnet armature (Ma) is set to the same zero position for any load. This embodiment permits the provision of accurate, temporarily stable compensating scales which are noise-immune and have a high lifting force. <IMAGE>

Filed: 1977-06-07
Abstract: A sensor at a relatively high temp. is immersed into a sample of the tested liquid. It is cooled down to a first temp. at which the presence of a contamination begins to have an effect on the liquid cooling. The rate is measured at which the sensor cools down from the first temp. to a second, lower temp. The liquid is typically an annealing, quenching or hardening oil, for which the temp. range appropriate is 500 deg.C to 200 deg.C. The sensor is pref. in the form of a long bolt of stainless steel.

Title: Transmission of higher hierarchic order digital signals - uses several digital signals of lower order bunched and converted into phase shift keyed signals
Inventor: REHM HANS DIPL ING
IPC: H04L5/12
Filed: 1977-09-22
Abstract: The signals are transmitted by bunching several digital signals of lower hierarchic order and of the same bit rate, with conversion into phase shift keyed signals. Digital signals (a1, b1, a2, b2) of a lower order are precoded, so that precoded digital signals (alpha 1, alpha 1; beta 1, beta 2) are produced. Then a pair of such signals (alpha 1, alpha 2; beta 1, beta 2) are combined in bunched signals (A, B) with a higher bit rate, multiple phase shift keyed and combined into a signal to be transmitted. At the receiving end they are reconverted to punched signals (A, B) by time delay demodulation, signals (A, B) are scanned by pulse trains with shorter pulse width, thus recovering the lower order signals (a1, a2, b1, b2). Then individual pulses are widened and converted into the NRZ form suitable for further processing.

Title: lacquer contg. iron particles - used to effect adhesion between articles by magnetic attraction
Inventor: SENCKEL HANS-JOACHIM
IPC: C09D5/23
Filed: 1978-02-15
Abstract: The surfaces of objects can be made to adhere without damage, and be sepd. again as easily, by coating the object with a colourless or coloured lacquer into which magnetised iron powder or cuttings have been mixed. Conversely, the lacquer may contain iron particles which have not been magnetised so that the object coated with it will adhere to a magnetic surface. Similarly, magnetic iron powder may be mixed into glass to give a solid body with magnetic characteristics.

Title: Casting metal into elongated high conductivity mould - to form solidifying casting shell and flowing liquid core
Inventor: WATTS LEONARD
IPC: B22D7/02
Filed: 1978-07-12
Abstract: A metal article is cast in an elongated mould of high thermal conductivity by introducing molten metal through the bottom portion of the mould. Molten metal is flowed into the mould so as to form a solidifying casting shell which during casting occupies >=40% of the cross-sectional mould area and has a molten core. The metal is flowed until the shell extends to the mould top and the core is subsequently solidified. Used for casting billets. The molten core sweeps the solid-liquid interface formed by the shell and inhibits columnar dendritic growth during filling of the mould. Several moulds may be filled simultaneously from a single molten metal source. The inclusions and impurities tend to be carried to the top of the mould. Centre line porosity is minimised.
