Patent DE-2150876-A1 (DE)
Title: Inner ball race rings automatic prodn - on multi-station machine with single drive motor
Inventor: GOGUTA TRAIAN
IPC: B21K1/04
Filed: 1971-10-13
Abstract: Inner ball race rings are cut from a length of tube and formed in a pressing operation on a single machine. A crank shaft drives two horizontally opposed dies through a connecting rod and toggle mechanism at half the speed of a device for shearing the correct length of tube, with a mandrel inside it, and lowering it into the pressing position. The same drive is used with different gear ratios for all parts of the machine including tube feed, mandrel removal, and return to cutting station. In previous machines very accurate cutting was required to allow precise centering in the press tools.

Title: Dough kneading machine - with conveyor troughs lined with felt strips to form a ball
Inventor: HUEBNER KARL
IPC: A21C7/01
Filed: 1972-02-15
Abstract: A dough kneading machine contains a trough into which a cut-off dough section is dropped. A brush distributes flour to prevent sticking. As an endless conveyor belt at the bottom moves the dough along the trough, felt strips along the sides tend to hold it back so that it is rolled into a spherical form. A semicircular felt-lined cover over the trough improves the shape of the dough ball.

Title: Large screen scanning laser T.V. projector - has rotating polygonal mirror cylinders behind screen
Inventor: BEER WOLFGANG
IPC: G03B15/08
Filed: 1973-08-20
Abstract: The screen has a height to width ratio of 3 : 4. One polygonal mirror cylinder is placed below the level of the lower edge of the screen and a short distance behind it. The cylinder length is approximately equal to screen width. The second mirror cylinder is placed at right angles to the first and near to one end. It reflects the modulated laser beam on to the first cylinder which in turn projects it on to the screen. The number of polygon sides and the speed of rotation is arranged so that the line by line scan matches the norm of television transmissions. The laser beam is modulated by the television signal. The design is claimed to produce a large bright picture, to be compact and independent of the shape and size of the auditorium.

Patent DE-2409677-A1 (DE)
Title: Arrangement to produce contact screen pattern - by exposure of light-sensitive material generates pattern on cathode ray tube
Inventor: KASAKOW EDUARD S
IPC: G03F5/16
Filed: 1974-02-28
Abstract: The apparatus has a cathode ray tube, a cathode, a modulator and control electrodes. There is a cylindrical drum in front of the screen of the CRT around which a photographic film is wrapped. The drum, rotates on a shaft carrying a perforated disc. A light source is on the drum side of the disc and a photo transformer on the other. The CRT moves on a carriage parallel to the drum axis. When the drum rotates the holes in the disc interrupt the light source which gives a signal from the photo transformer to the square wave impulse generator. The frequency found reaches the modulator. This breaks the light impulse and activates a generator. Its signals control the size of the light spots during exposure of film.

Title: Hotplate for quick cooking - has electro-magnet preventing children from pulling down pot
Inventor: HUETTERMANN THEODOR
IPC: F24C7/08
Filed: 1974-04-19
Abstract: Electric hotplate for cooking range comprises an electro-magnetic mounted in a central recess in the hotplate, which when switched on magnetically retains the cooking pot on the hotplate. The electromagnet may be switched on and off independently of the hotplate, so that the pot is still retained when cooking is complete but the pot is still hot. The magnetic force increase application of the pot to the hotplate, providing more direct heat transfer. The magnetic holding provides a reliable safety device preventing accidental tipping over, but especially for children whose curiosity about contents or even eagerness to help can not always be adequately or conveniently supervised. It also leaves a hand free by stirring etc.

Title: Setting and controlling constant tension in fibre tow - driving guide roller pair auxiliary by driven feed roller pair to generate tension controlling current
Inventor: WOLBER JOSEF
IPC: B65H59/38
Filed: 1974-04-27
Abstract: Present tension of a fibre tow is controlled to maintain it at a constant value by drawing the tow by means of a first pair of rollers which are driven at a high speed by a dc motor through the nip of a second pair of rollers which are driven by a second dc motor at a lower speed and driving the second pair of rollers by the first pair of rollers to bring it up to the speed of the first pair of rollers and thereby generate a current which is applied to a measuring device which derives it as signal for the tension control.

Title: Universal rolling mill - designed for rapid sideways extn and replacement of rolls
Inventor: BUCHHEIT OTTO KARL
IPC: B21B31/04
Filed: 1974-09-11
Abstract: Rolling mill, esp. a universal rolling mill, in which the dia. of the horizontal rolls is larger than the clear space in the windows in the roll-housings, and where the housings consist of at least two parts held together by a pair of tie-rods. The novelty is that in order to permit the sideways extn. of the rolls, the pillars which act as the side guides for the chocks contg. all the horizontal rolls, complete with the cross-head joining the pillars, are lifted and the space between the tie-rods, at least on the extn. side of the mill, is larger than the dia. of the horizontal rolls so the latter can pass between the tie rods for the simultaneous removal of both the horizontal and the vertical rolls. The monolithic upper part of the housings can be lifted by a crane while remaining on the tie rods so the set of rolls can be removed and replaced sidewards very rapidly, i.e. the upper housing does not have to be re-located on the tie-rods.
