Patent DE-2224469-A1 (DE)
Title: Anti friction bearing ring rolling machine - with roll pressure variation system
IPC: B21H1/12
Filed: 1972-05-19
Abstract: A pressing mechanism applies a continually changing rolling force to the rolling mandrel. The force size variation is effected in dependence on the decrease in thickness of the workpiece ring wall, thus corresponding to the change in resistance against deformation by the ring material at opt. stress conditions. Pref the pressure is generated hydraulically or pneumatically. The system prevents application of excess rolling forces causing crack development on the rings.

Title: Seal between moving and fixed frames of windows or doors - has overlapping seal for connecting with a projecting rib on a frame part
Inventor: SITTMANN GEB VOESTER BRIGITTE
IPC: E06B3/40
Filed: 1973-07-19
Abstract: The seal arrangement is used for panels which have a central rotating axis. The overlapping seals are used in conjunction with the frame rotated about the axis. These sealing strips are arranged in opposition because the rotating halves of the frame approach the fixed frame in opposite directions. The sealing strips can be exchanged and are of identical shapes. The sealing strips can be keyed in the frame by dovetail profiles. The long overhanging lip of the seal ensures good sealing contact with the profile of the frame.
Patent DE-2337409-A1 (DE)
Title: magnetically actuated push-button switch - has permanent magnet moving with push-button, and indicating light with contact springs
Inventor: GUERTH MAXIMILIAN
IPC: H01H13/02
Filed: 1973-07-23
Abstract: The permanent magnet is moved by the push-button which is formed, at least partly, by the light indicator. The latter has contact springs, one of which acts simultaneously as a resetting spring for the push-button. The contact springs may be formed by leaf srings which are clamped on one side in a housing across the direction of motion of the push-button element. Their other ends are embedded into the light indicator body together with the permanent magnet. The length of the contact springs affords linear motion of the push-button during switch actuation. The light indicator may be a photo-diode or another component resistant to impact, such as a liquid crystal display element.

Title: Polyethylene of controlled mol. wt. distribution - obtd using transitional metal catalysts activated by aluminium hydrocarbon cpds
Inventor: DOERK KLAUS DIPL-CHEM DR
IPC: C08F10/02
Filed: 1973-08-01
Abstract: Prodn. of polyethylene with controlled mol. wt. distribution is carried out by polymerisation of ethylene, opt. in admixt. with propylene and/or butylene-(1), as well as in the presence of H2, and a catalyst comprising a mixt. of two transitional metal components A and B activated by an aluminium hydrocarbon cpd., the mol. ratio of A : B being 1 : 20 to 1 : 0.1, where A consists of chromium (III) acetylacetonate absorbed on silicic acid, and B consists of either (a) TiCl3 obtd. by organometallic reduction of TiCl4, or (b) liquid hydrocarbon-soluble mixts. of V and/or Ti cpds. reduced by an organometallic cpd. The mol. wt. distribution is wider, the larger the propn. of component A. The polymerisation is effected under the usual conditions for low pressure Ziegler polymerisation, e.g. pressures of 1-100 atm., pref. 10-50 atm., and temps. of 20-100 pref. 60-90 degrees C. The process yields polyethylene and copolymers with propylene and/or butylene which can be processed in high performance extruders to yield hollow articles, tubes, etc. having good stress-cract resistance, impact strength and stiffness.
Patent DE-2339946-A1 (DE)
Title: Transfer installation for masonry slabs - has transfer arm for placing plates vertically onto exit conveyor
IPC: B65G49/08
Filed: 1973-08-07
Abstract: A press form carrying a number of finished slabs is positioned over a trolley. The plates are pushed out of the forms onto the boards on the trolley. The trolley is then horizontally moved until it is vertically above two roller rails. By lifting the rails until the boards clear the trolley, they are free to move down the incline of the rails towards the transfer arm. the transfer arm picks ukp a board and by rotating it through 90 deg. places the slabs vertically onto the exit conveyor. The empty board is then placed on a return track which is vertically below the feed track from where it returns to the loading station. This method allows a continuous operation cycle which at the same time ensures that the required time interval between forming the slabs and transfering them is maintained.
Patent DE-2340827-A1 (DE)
Title: Hanger conveyor system for large flat objects - enables transfer at right angles between two parallel conveyor sections
Inventor: ERTELT MANFRED
IPC: B65G47/61
Filed: 1973-08-11
Abstract: A hanger conveyor circuit conveying large flat objects say doors or frames, with their long dimension at right angles to the direction of motion, is provided with a transfer hanger-conveyor to remove the objects from one leg of the conveyor and transport them with their long dimension in the direction of motion and replace them on another parallel leg of the conveying system. This is especially suitable where bend radius in the conveying system would be too small for the objects not to touch during transport.
Patent DE-2341271-A1 (DE)
Title: Gymnastic parallel bars - have constant-tension bracing cables for long and short posts with variable spacing of crossbars
Inventor: JANSSEN JACOBUS MARINUS HENDRI
IPC: A63B3/00
Filed: 1973-08-16
Abstract: Gymnastics parallel bars have crossbeams supported by posts at different heights; tension cables of constant length engage the upper regions of the short and long posts at both ends of the bars, and each extends away obliquely from the cross beam and is anchored to the floor. The horizontal spacing between the crossbeams is adjustable in cooperation with the cables, with rotation of the post about its bottom end in a vertical plane, using a guide for the cables mounted at the top of the short and/or long post and displaceable relative to the cable by displacement from outside without changing the cable tension. In each set position, the guide can be anchored relative to the cable. The simplified appts. no longer requires coupling nut and equaliser, and the cable tension need not be adjusted for each new position.
Patent DE-2341637-A1 (DE)
Title: Safety cut-off for car ignition - involves inertial switch to cut-off battery and connect ignition to earth
Inventor: JANSSENS JOHANN
IPC: B60K28/14
Filed: 1973-08-17
Abstract: An electromagnetic relay is connected in series with an inertial switch to supply current from the battery via the ignition switch. The inertial switch has an inertial mass which is displaced by a collision to interrupt the light path between a bulb and a photosensitive switch. This switches the relay between the live contact and earth and thus immobilises the ignition, even with the dynamo still turning. The system is thus fail-safe and reduces the fire risk during a collision.

Abstract: The processing tank forms a light proof chamber with trough shaped internal floor of approximately semicircular cross section. A drum carrying the photographic material is mounted on a spindle so that its lower portion is suspended slightly above the trough floor. The drum can be cylindrical, fitted with paddles or radial partitions. In either case, spirally inclined fins ribs or tongues are provided at the periphery. These impart an axial flow component on the tangentially propelled solution when the drum rotates for improved mixing and more even development. The design allows existing equipment to be modified by simple drum replacement.
