Title: N-Channel storage FET with one or several gates - has conductive strips coating connecting region and charge reversing region parts respectively
Inventor: ROESSLER BERNWARD DIPL ING
IPC: G11C11/24
Filed: 1976-09-29
Abstract: The storage field-effect transistor is intended for programme memory of a telephone exchange system. It has a floating storage gate surrounded completed by an insulator. Highly accelerated and heated electrons in the transistor conductive channel are utilised, after injection, for the charge reversal of the storage gate. After heating the electrons overcome the energy threshold, due to an electric field effective in the source-drain direction. The acceleration is initiated by a channel injection which is used for programming, i.e. charging of the storage gate. After charting the gate affects the source-drain path in a current restricting manner by its negative charge, as in 2445137. Two conductive strips (L1, L2) are connected to the storage gate (G1), the first strip (L1) covering a part of a connection region (S, D) of the drain or source, while the second strip (L2) covers a part of the charge reversal region (B, X).

Title: Press for cold forming long profiles - has hydraulic cylinder mountable in two positions for pressing form tool and twisting work
Inventor: BOEHL HANS-ERICH
IPC: B21D11/14
Filed: 1976-10-30
Abstract: The arrangement consists of a console (60) with a mounting bracket (61) for a hydraulic cylinder (D). The hydraulic cylinder can be mounted in one of two positions. In one position, the cylinder presses a form tool (71") against the side of a section of a material (B) and gives it a local deformation. The cylinder can also be mounted in a position which is at 90 deg. to the first position. In this position the cylinder can exert a force in the longitudinal direction of the material, to compress it endwise e.g. when several sections are twisted together.

Title: Pressure operated tube sealing cap - has elastic membrane with hole lifted off sealing body by pressing tube
Inventor: BACHMANN GUENTHER
IPC: B65D47/20
Filed: 1977-02-02
Abstract: The pressure-operated sealing cap is for tubes and all kinds of elastic container. An elastic membrane (1) with a hole in it is sealed by a body of any desired shape (2) in the rest position, so that none of the tube contents can escape. On pressing the tube, the membrane is lifted off the body and the contents continue to emerge through the hole until pressure is released, when the elasticity of the membrane causes it to shut the hole off again. The membrane can be a rigid plate, being elastically held in position by a bead or bellows. The membrane, cap and body can be a one-piece plastic injection moulding.

Title: Icing sensor with integral test equipment - has window flush with relevant surface which, when iced up, reflects light to detector via focussing lens
Inventor: EUER HARTMUT ING GRAD
IPC: B64D15/20
Filed: 1977-02-18
Abstract: The icing sensor with integral test equipment comprises a window (1) of a very hard, scratch- and erosion-resistant material such as sapphire illuminated by a light source (2), fitted flush with the relevant surface (6). If ice forms on this window it reflects scattered light which is taken via a focussing lens (3), to a receiver (4) coupled to an electronic intensity of icing indicator (11). For testing the system itself a liq. crystal reflector (5) is fitted between light source and window. If a potential difference is applied across this it simulates the iced-up state of the window.

Title: Bridge expansion joint bending moment hydraulic transfer - involves paired hydraulic presses with front and rear chambers diagonally linked
Inventor: LEONHARDT FRITZ PROF DR ING
IPC: E01D19/06
Filed: 1977-03-19
Abstract: In bridge construction, and other beam-type structures, the assembly for hydraulic transfer of bending moments at expansion joints comprises hydraulic presses with two successive pressure compartments (a, b) separated by their pistons. At least two such presses are installed, parallel to each other, in the structure's expansion joint. The forward pressure compartment in each (a1, b1) is connected to the rear compartment (b2, a2) on the other pressure ducts. Where there are four presses in a rectangular pattern, the diagonally facing ones may be similarly interconnected. The pressure ducts may be kept under different pressure, and/or have provision for compensation. This facilitates direct transfer of bending moments.

Title: Catalytic oxidn. of sulphur di:oxide to sulphur tri:oxide - for sulphonation and sulphation of organic material using optimum temp. profile
Inventor: SOJKA VLADIMIR DIPL ING
IPC: C01B17/76
Filed: 1977-04-15
Abstract: Catalytic oxidn. of SO2 is carried out by contacting a gas mixt. contg. 8-13 vol.% SO2 and 5-13 vol.% O2 with the catalyst. The gas mixt. is at 20-80 degrees C below the ignition temp. of the catalyst, whilst the catalyst is kept at 420-580 degrees C by indirect heat exchange, with condensn. of vaporisation of S at a pressure of 0.6-1.2 kp/cm2. The equipment consists of a jacketed exchanger with catalyst-filled tubes surrounded by sulphur in liquid/vapour phase. Process is used for prodn. of a gas mixt. with a SO3 partial pressure of 65-85 torr, which is often used for the sulph(on)ation of organic materials. It ensuresd that the catalyst operating temp. profile is close to the optimum, so that the amt. of catalyst needed is near the theoretical amt. Controlled dissipation of the heat of reaction in the first stage is possible and the lower gas temp. also excludes the risk of catalyst deactivation or damage by overheating. Very simple equipment is used.

Title: Separator for slurries of particulate solids - having flexible pipe held between two concave shells mounted on eccentric shafts to give upward movement to solids
IPC: B30B9/02
Filed: 1978-02-08
Abstract: Solid-liquid slurries are sepd in device consisting of flexible pipe hold between concave shells. These shells are mounted on eccentric shafts and driven by a common coordinated drive.
