Patent DE-2332596-A1 (DE)
Title: Chair with backrest jointed to seat - variable length thrust rod on forward part of seat
Inventor: ZIEGLER HORST
IPC: A47C1/032
Filed: 1973-06-27
Abstract: The forward part of the seat is suspended, by another joint connection, in carrier arms rigidly attached to the underframe. A support rod is jointed at one end to a carrier arm and at the other end to the thrust rod or the backrest. Preferably the joint connection in the forward part of the seat is above its forward edge, and the support rod is jointed at a point on the carrier arm between this joint connection and the underframe, and also at a point at which the thrust rod is connected to the backrest. The angle of inclination of the seat and the backrest can be altered by a simple mechanism in different relation to each other, while the height of the forward edge of the seat is unchanged.

Title: Concave skittle alley surface - made to various curvatures using preformed polished metal plates to press plastics board
Inventor: SCHMEING ALFONS
IPC: A63D1/04
Filed: 1973-07-09
Abstract: A method of making a highly polished concave surface on a pressed plastics board, esp. for a skittle-track, consists of curving the board elastically, then grinding flat its lower face, the polished face remaining as the concave, unground, upper side. Also claimed is the appts. for curving the board and it consists of a metal plate with one highly polished face which is caused to sag on a temporary support and clamped, and then ground flat on the concave upper face. It is then used (the same way up) as a pattern for pressing into the upper face of the plastics board. In the initial shaping, the temporary support is formed of strips, to suit the particular local curvature desired.

The collar acts as a floor seal; drain holes lead into the trough's interior.
Patent DE-2336295-A1 (DE)
Title: Rolling machine for bending profiled members - stretches straight profiles of any given length using rolling method
Inventor: KIRSCHNING HANS JOACHIM DR ING
IPC: B21D7/08
Filed: 1973-07-17
Abstract: The profiles which are initially straight are curved by passing them between two pairs of rolls which impart stretching action on the profile. Rolls whose axes of rotation are on a line at right angles to the profile longitudinal axis rotate at a different speed to a further pair of rollers. The latter pair rotates faster and exerts stretching force on the profile. The lines joining the centres of the two pairs of rolls are inclined at an angle to each other and this angle can be adjusted to suit the required curvature. Application of tensile forces on forming eliminates any bulging and distortions.
Patent DE-2338178-A1 (DE)
Title: Sealing aluminium oxide coating with silicic ester - to improve insulation of cathode-heating coil in electron beam lamps
Inventor: MERK HANS
IPC: H01J9/08
Filed: 1973-07-27
Abstract: Insulating ability of an aluminium oxide coating on heated parts of a cathodic tube, esp. the cathode-heating coil, is improved by immersing the alumina-coated part in a hydrolysed silicic ester, esp. hydrolysed methyl or ethyl ester of orthosilicic acid; then drying and firing. Pores of the aluminium oxide coating are plugged with silica; this effect is due to the use of a hydrolysed silicic ester. The service life of the coating is extended.
Patent DE-2338305-A1 (DE)
Title: Double refraction measurement method - uses electromagnetic wave spectrum in ultra-violet, visible and infra-red ranges
Inventor: FRANGEN JOCHEN DR-ING
IPC: G01N21/21
Filed: 1973-07-27
Abstract: By this method, and using polarisation optical systems the double refraction in optically active materials can be quickly determined, thus obtaining a test quantity by which the anisotropy produced in the finished transparent or translucent object by the manufacturing processes, and thus the object quality can be judged. An analysis of the transmission or absorption spectrum is used for determination of the propagation difference of the perpendicular to each other light wave component of a linearly polarised input light wave, produced by the existing anisotropy; the test result is used as output signal for control of a manufacturing process, e.g. of a plastic foil, or for continuous or quasi-continuous quality control by computer.
Patent DE-2341669-A1 (DE)
Title: Activation of audio tape stopping mechanism - involves using light source and photosensitive cell to sense translucent section in tape
Inventor: HERLETH KARL
IPC: G11B15/08
Filed: 1973-08-17
Abstract: There is a light source working in conjunction with a photosensitive cell to sense a translucent section near either end of an audio tape in a cassette, so as to stop or brake the tape transport mechanism. To avoid damage to the tape due to heat radiation from the light source, this is now mounted below the base plate and its light is directed through a prism. A surface of the latter directs the light towards the tape so as to sense a translucent area by passing through it to a photosensitive cell which actuates the motor-stopping mechanism.
Patent DE-2345200-A1 (DE)
Title: Shoe toe support for a heel attaching machine - has automatic adjustment device for adjusting distance between shoe tip and heel supports
Inventor: SCHINDLER HERBERT
IPC: A43D23/02
Filed: 1973-09-07
Abstract: The heel support is in contact with the inside surface of the shoe when it is turned upside down for heel attaching by a vertically acting tool. The machine senses the distance between the toe and the heel for correct adjustment of the support system by photoelectric cells supported by the toe supporting column. The light bram of these photoelectric system arrangements are directed at 90 deg. to the plane which contains the centreline of the heel supporting column and the toe supporting column. Light signals are fed into a discriminator for evaluating and generating a signal for adjusting the shoe toe tip support. This arrangement does not require a great deal of attention on operation. Shoes of any size can be passed through this seam without regard to their size.
Patent DE-2345815-A1 (DE)
Title: Removing selenium from molten copper - by treatment with alkali sulphide
Inventor: LARSON HAROLD RICHARD
IPC: C22B15/14
Filed: 1973-09-11
Abstract: Copper refined by electrolysis contg. Se is melted and treated with alkali sulphide, by maintaining contact between the sulphide and the copper, in the form of a matte for long enough to reduce the Se content to  a preset value, then separating the copper from the matte. A carbonaceous reducing agent mixed with alkali sulphate may also be used. The Se, which alters the heat treatment properties of copper drastically reacts pref. with the alkali metal. The process does not introduce excess oxygen.

Title: Protective layer against ground effects - bee's wax protects against radiations rising dampness or other irritants
Inventor: SOHR ALOIS
IPC: A61N1/16
Filed: 1973-12-05
Abstract: Screen for protection from ground irritations and fields consists of a substrate to which is applied bees' wax.

Bees, in opposition to other creatures, seem to prefer some regions and wax has been shown to afford a marked shielding action.
Patent DE-2362677-A1 (DE)
Title: Metal tubing with anti-corrosive inner - with roughened metal liner between outer and inner plastics tubing
Inventor: HAGEN HERBERT
IPC: F16L58/10
Filed: 1973-12-17
Abstract: The inner tubing made of plastics, is initially inserted into the outer tubing with a clearance therebetween and is fixed into position by contraction of the outer tubing. The liner is made of sheet metal and is provided at least at its interior with small projections. The liner is inserted into the clearance before the contraction process and during that process the projections of the liner become embedded in the outer surface of the plastics inner tubing thereby to inhibit differential expansion between the inner and outer tubing. The liner may be a spirally wound or slotted tube.

Patent DE-2440684-A1 (DE)
Title: Hydraulic check valve with spherical seal body - has convergent nozzle to replace seal body return spring
Inventor: LANG ARMIN
IPC: F16K15/04
Filed: 1974-08-24
Abstract: A hydraulic check valve has a spherical sealing element (5) which lifts off the valve seat (4) in the direction of the free flow. A restrictor ring (7) passed into the valve chamber has jaws (10) which limit the travel of the sphere (5) and guide it radially to keep it concentric with the valve seat (4). Part of the restrictor ring (7) forms a convergent nozzle (9) so that any oil flowing against the free flow is accelerated. This enables even a very small oil flow velocity to force the sphere onto the valve seat, thus closing the valve. A hydraulic check valve without mechanical return element is thus obtained.
