Title: Lenticular grating for projecting stereo image - has aperture ratio of lens elements reduced to one sixth to one tenth to give good image quality
Inventor: DEML REINHOLD DIPL PHYS DR
IPC: G03B35/00
Filed: 1980-12-22
Abstract: The arrangement is intended for producing a stereo image, observable without any viewing aid, by projecting a number of two-dimensional photographs of an objective, taken from adjacent positions, onto a screen or light-sensitive surface in front of which a lenticular grating is arranged. It has a predetermined grating width and a number of linear image bands. The aperture of the individual lens elements of the lenticular grating is reduced from the commonly used aperture ratio of 1:2 or less to a value of 1:6 to 1:10, e.q. by partially lacquer-covering the valleys between these elements or by interposing a correspondingly obscuring grating.

IPC: H01H33/91
Filed: 1981-08-27
Abstract: An electric switch includes two quenching nozzles which are arranged opposite each other at the distance of the switching gap; a contact tube; a guide tube and a longitudinally movable switching tube for bridging the switching gap which is coupled, together with a movable pressure piston of a pressure piston/pressure cylinder arrangement provided for generating a quenching medium flow acting on the arc, to a common drive. In order to improve such a switch still further with respect to the quenching medium flow, the pressure piston is connected rigidly to the switching tube and is arranged in a stationary pressure cylinder which is connected in the region of its end surrounding the contact tube via passage openings in the contact tube to the interior of the latter. The pressure piston is connected rigidly to a suction piston in a suction cylinder which is connected in the region of its end facing the pressure cylinder, via holes in the guide tube, to the interior thereof.

Patent DE-3141787-A1 (DE)
Title: Tubular mast comprising tube bodies which are plugged one onto the other
Inventor: DUPPACH JOSEF
IPC: E04H12/08
Filed: 1981-10-21
Abstract: The invention relates to a tubular mast comprising lengths of steel tube which are plugged one onto the other and the diameters of which become smaller towards the tip of the mast and exhibit a conically drawn-in portion, at the upper end of which there is formed a circumferential shoulder on which the plugged-on length of tube is fitted with the aid of a conical clamping bush which is plugged therein and, for its part, is plugged over a conical, tubular continuation which belongs to the lower length of tube and via which the frictional and clamping forces, necessary for holding the lengths of tube together, are transmitted. The lengths of tube designed in this way do not need to be braced, welded or adhesively bonded to one another. They permit the assembly, at the site of erection, of tubular masts of any length, as a result of which considerable transportation and storage costs are saved. The configuration of an annular flange at the lower end of the clamping bush, which flange cannot be brought into direct contact with the circumferential shoulder of the lower length of tube when the upper length of tube is plugged on, simplifies the assembly and the sealing of the individual lengths of tube since it fulfils simultaneously the function of a sealing and spacer ring.

Title: Slack reinforcement for reinforced concrete components subjected to bending stress
Inventor: STEWING ALBERT
IPC: E04C5/02
Filed: 1982-01-09
Abstract: The invention relates to a slack reinforcement for reinforced concrete components subjected to bending stress and having inserted tension members. This reinforcement is characterised by closed reinforcement loops comprising members connected to one another at their ends in the form of a loop, the reinforcement loops possessing the tension members of a truss frame having, for example in the case of a single-span beam, loop ends raised into the upper corners of the beam. In combination with this, provision is made for part of the reinforcement loops to form the tie member of an arch/strut frame having flat-lying loop ends. By virtue of the combination of the truss-frame analogy with the arch/strut-frame analogy, a particularly economical reinforcement is made possible, which confers the particular reinforced concrete component high bearing capacity. <IMAGE>

Title: Mounting device for objects such as structural parts, walls, screens, plates or the like on mast-shaped, tubular or rod-shaped supports, for example for the fitment of information plates on pipelines
Inventor: MUELLER FRANZ
IPC: F16B2/08
Filed: 1982-01-15
Abstract: In a mounting device for objects such as structural parts, walls, screens, plates and the like on mast-like, tubular or rod-shaped supports, which contains a hollow base piece, a clamping strip and a clamping device arranged in the interior of the base piece, a clamping slide is provided as the strip holder and part of the clamping device and in each case one buttoning-in element for the perforated strip ends is fitted to its back holding the ends of the clamping strip on both sides of a central retaining hole for the clamping screw, matched to the hole separation in such a manner that the two strip ends can be buttoned in on both their sides beyond the retaining hole for the clamping screw and hence leave the access to the retaining hole free by means of their holes. As a result of elastic flexibility of the buttoning-in elements and of the entire clamping slide, it can be achieved that, during clamping, the holes in the clamping strip ends are drawn with their edges directly onto the clamping screw and are drawn into its thread. The base element and the clamping slide can be combined via a connecting strap which can be torn off to form a unit which can be injection moulded in a simple manner in a plastic mould which can be opened in only one plane. As a result of this base piece/clamping slide unit, the production process, storage and assembly are considerably simplified.

Title: Sprue bush for injection-moulding apparatus
Inventor: GELLERT JOBST ULRICH
IPC: B29C37/00
Filed: 1982-01-21
Abstract: A sprue bush (10) for an injection-moulding apparatus includes a hollow, inner core piece (20) of stainless steel, through which a through-channel (16) extends from the injection-moulding machine to the gate and around which there is arranged a helically wound electric heating element (32). The heating element (32) and the inner core piece (20) are cast with a highly conductive cast part (34) of copper and covered by an outer shell (40) of stainless steel. Fastened in the through-channel (16) is a spiral inner body (42) of steel, by which a rotating or swirling motion is imparted to the melt upon flowing through the gate into the mould cavity (18). This has the advantage that, by reducing the molecular orientation of the melt in one direction, the strength of the product increases and any threading of the melt upon opening the mould for ejecting the product is reduced. <IMAGE>

Title: Circuit for preventing high surge loads
Inventor: GASSMANN GERHARD-GUENTER
IPC: H02J13/00
Filed: 1982-01-26
Abstract: The invention relates to the circuit for preventing high surge loads from power supply networks, as occur when a very large number of loads are switched on simultaneously during the transition to the night-time supply in a ripple-control system. According to the invention, the switching-on surge is prevented in that a switching-on delay is connected upstream of every load, whose delay duration is random within a predetermined maximum time period, and thus a gradual rise in the load at the power station is achieved.
