Patent DE-2415954-A1 (DE)
Title: Automatic engine braking control - uncouples motor at minimum engine speed and introduces gradual braking
Inventor: KLANNER RUDOLF PROF DR ING
IPC: B60T11/10
Filed: 1974-04-02
Abstract: The vehicle is provided with a transmission brake coupled to a special control which disengages the coupling between the engine and the wheels below a set speed, providing the engine braking control is operating. This is controlled by a first section of the brake pedal travel, which is not sufficient to apply the wheel brakes. When the transmission coupling is about to disengage, a time delay circuit operates to delay the uncoupling until the automatic control can apply the wheel brakes smoothly and for a set amount. The vehicle retardation then progresses smoothly without any sudden jerks. The system is especially suitable for buses in hilly areas.
Patent DE-2416223-A1 (DE)
Title: Locking cattle - yoke for milking parlours - consists of uprights on each side of stall with pivot-hinged bars joined by wire on pulley
Inventor: HACKER JOSEF
IPC: A01K1/06
Filed: 1974-04-03
Abstract: The pens are separated by vertical hollow-tubutlar posts, to the exit side of which is fixed a tubular locking bar. Each vertical post is welded to a horizontal tubular support on which pivots each locking bar. Each horizontal support is joined to the vertical post on the exit side by means of a boundary piece. The horizontal support and the hinge are positioned beneath the cow's body height. Above the cow, the locking bars are moved in the same direction by means of two horizontal guide-rails. Between the guide-rails are stop-pieces. All the locking-bars are joined by a cable passing over a pulley which has stop-pieces on it corresponding to the hinge-points of the locking bars.

Patent DE-2420019-A1 (DE)
Title: Oil level control in crankshaft sump of I.C. engine - is automatically regulated by magnet and a float arrangement
IPC: F01M11/12
Filed: 1974-04-25
Abstract: A separate clean oil supply tank is conected to a tube which replaces the dip stick. A float, in the lower end, of the tube, is able to rise to and adhere to a permanent magnet thus closing an oil feed opening. An electric current keeps the float, against the magnet when the engines is running and a pusher rod, will separate float from magnet when the engine is switched off. This should avoid over filling the sump and keep it at the correct level.
Patent DE-2425412-A1 (DE)
Title: Vehicle electronic flasher control circuit - with switching transistor for accurate monitoring of flasher current for bulb failure
Inventor: SEITTER WOLF
IPC: B60Q1/38
Filed: 1974-05-25
Abstract: The electronic flasher control comprises an astable switching circuit in which a single transistor has a switching relay in its collector circuit to produce the flasher frequency. This frequency is determined by an RC circuit and is altered by a current monitor when a lamp fails. The current monitor has a switching transistor with a current monitoring resistance in the emitter circuit. The base is coupled to a predetermined bias. If a lamp fails then bias exceeds the emitter bias and the transistor is switched into the conducting mode. The system operates without the dead time associated with current monitoring relays, which can lead to 'flutter' in the single transistor.

Title: Welding jig for car welding repairs - is fitted over engine to support new panels being fitted
IPC: B25B11/02
Filed: 1974-06-12
Abstract: The welding jig has a metal frame which fits over the engine and has legs which support the jig either on the ground or on suspension frame members. Adjustable frame members can be set to support the new panels and hold them accurately for welding. The frame enables frontal body damage to be repaired without having to remove the engine/transmission. The frame holds the new sections accurately in position, and also enables the repairer to use the frame to determine the amount of bending he has to perform on the rest of the body before fitting the panels.

Title: Concentrating and cleaning aluminium hydroxide gel - in centrifugal-cleaning filter provided with rotating filter disc
Inventor: MUELLER HANS DR ING
IPC: B01D37/00
Filed: 1974-08-05
Abstract: Aluminium hydroxide gel, esp. sterile gel carrying bacteria or virus antigenes for medical or veterinary uses, is purified and concd. by filtering in a centrifugal-cleaning filter provided with a filter disc, which can be periodically rotated to effect centrifugal removal of the gel clogging the filter pores. The filtering time is greatly reduced. The rotation of the filter disc results in homogenisation of the gel, whereby its concn. is greatly increased (to 4-8% of dry substance compared with 1-2% in conventional filters). The concd. gel can be easily diluted to the required concn.

Title: Pivot link for engine bonnets - has upper link with recess into which lower link latch meshes to secure open position
Inventor: GFROERER KURT
IPC: E05D11/10
Filed: 1974-10-31
Abstract: The pivot link is of two parts, of which the upper section (3) is pivoted to the engine bonnet and the lower part (2) is pivoted to a suitable rigid paint on the vehicle. The two parts are joined by a bolt and a pressure spring at their free ends. To secure the bonnet in an open position, one link is provided with a projecting stop (10) against which a stop (11) formed on the second link presses. By compressing the spring, the stop becomes ineffective and the linkage is able to fold. The axial displacement of the one link in order to compress the spring follows by means of a manual lever (12) with two opposite laying cam faces pivoted between the two links.

Abstract: Tin or jar type container protects products such as cremes, pastes or ointments from counter influences and deterioration even during use. The container is totally enclosed including during the use of contents which are only allowed to pass through a small outlet opening of varying size by the exertion of pressure on a tightly closed inner section. This pressure moves downwards in equal stages, the inner section having no edges. The outlet opening is located on this moving inner section and the outer section of the container is shaped so that the movable inner section fully displaces the product during the emptying process with only a minimal amount remaining in the outlet opening.

Title: Boiling water reactor circulating pump shaft intensively cooled - giving short shaft length to motor thus avoiding vibration
Inventor: ERIKSSON OLLE
IPC: G21C15/243
Filed: 1975-06-10
Abstract: An internal water circulating system for a nuclear reactor, esp. a boiling water reactor, comprises a circulating pump mounted inside the pressure vessel and driven by an externally mounted, water-cooled electric motor, the connecting shaft passing through an extension of the motor housing connected to the pressure vessel; there is a connection between the pressure vessel and the cooling channels of the motor via a cylindrical gap surrounding the pump shaft. The lower part of this gap is widened outwards e.g. conically, to form an annular space outside the pump shaft and inside the motor casing, inside this space there is a coaxial cylindrical partition, connected and sealed at its top edge to the inner face of the motor casing and bearing on its inner face onto the external side of an annular packing holder; this holder comprises one or more outer sealing rings and one or more inner sealing rings; the outer face of the cylindrical coaxial partition also forms the inner boundary to an annular cooling water chamber. The outer boundary to this chamber is pref. constituted of a thermally insulating lining to the motor casing, consisting of a number of parallel plates sepd. by distance pieces, the inter. spaces being filled with liq. It is possible for the total shaft length between pump and drive motor to be considerably shortened while still keeping the motor sufficiently cool. Thus the difficulties arising from critical vibration in a long shaft are avoided, since the natural frequency of this short shaft arrangement is always considerably higher than the excitation frequency.
