Patent DE-2927467-A1 (DE)
Title: Spring-loaded yoke for two pole armatures - provides support during turning on lathe and has roller support for smoothing vibrations and preventing ovality
Inventor: D HAM REINHOLD DIPL ING
IPC: B23Q1/76
Filed: 1979-07-06
Abstract: The two pole armature of a turbogenerator (1), when held in a lathe for machining has moments of inertia occurring with reference to the X and Y axis. The differences in elasticity of the armature (1) while being machined, can lead to ovality, and a support is necessary to prevent this. This takes the form of a spring-loaded rocker (43), on whose arm is mounted a pair of rollers (44). The underpart (41) of the telescopic housing is supported by the bed of the lathe, and contains the spiral spring (40), the upper part of which is covered by the housing itself (42). When being machined, the irregularities due to the grooves (2) are taken up by the support rollers (43) and the telescopic spring action. The spring can also be replaced by a hydraulic damping device which gives a similar absorbtion of uneven movement.

Title: Oil pressure maintaining valve for IC engine - has restricted outlet designed to maintain pressure constant with increasing speed
Inventor: SCHWAAR HANSJOCHEN DIPL ING
IPC: F01M1/20
Filed: 1979-08-22
Abstract: The oil pressure maintaining valve has a piston held on its seat by a spring at low speed and low oil pressure. At a given pressure, the piston lifts, and an oil flow commences through a restrictor, which has little effect, due to the low flow. As flow increases with speed, the pressure drop across the restrictor increases by the power of two, as does the pressure on the piston, which lifts increasingly. Delivery pressure remains effectively constant over a wide speed range.

Title: Apparatus for the supplying and discharging of animal feed
Inventor: SPROLL JOSEF
IPC: A01K5/00
Filed: 1981-03-31
Abstract: A comminuting mechanism (9) for tubers, such as beet, potatoes, pomaceous fruit and the like is mounted below the hopper (3) of a feed container (1) and has a cutter disc (14) which is seated on a cutter shaft (13) and rotates in an annular casing (8). The cutter shaft (13) is connected by means of a lower bevel gear (12) to a motor drive, such as the power take-off shaft of a tractor or a hydraulic motor, and supports a worm (18) which conveys upwards in the middle of the hopper, while small plates (23 and 21) which are mounted on the cutter disc guide the material to be comminuted into the region of the cutters (16, 17) and a doctor blade-like guiding element (22) presses the material, which has been carried along by the rotation, against the cutter disc (14). The comminuted material is conveyed horizontally outwards through a discharging pipe (28) by means of a centrifugal disc (15) and may, for example, be fed directly into a feeding trough. The feed is therefore placed in front of the animals directly after comminution and the total working time is significantly reduced, especially when the feed container itself is pivotably mounted on the tractor to act as a receiving scoop and takes up the feed directly from the floor of the store. <IMAGE>

Inventor: MAYER LOTHAR
IPC: H02M3/335
Filed: 1981-05-30
Abstract: A DC/DC voltage converter having mains power supply isolation for input voltages (UE) having an extremely large variation range contains a switching transistor (T3) in whose collector circuit there is located a transformer (Ü) having primary, secondary and auxiliary windings (1,2; 6,7,8; 3,4), and in whose emitter circuit there is located an emitter resistor (RE) on which a voltage (UE) is picked off which is proportional to the current (i). It furthermore contains a control-pulse circuit (ST) having a first circuit (IC1), which is connected as a voltage-controlled multivibrator and supplies triggering signals via a first differentiating element (C4, D4) to a second circuit (IC2) which is connected as a triggerable comparator. The comparator (IC2) compares the voltage dropped on the emitter resistor (RE) with a fixed reference voltage (Uref). The voltage produced in the auxiliary winding (3, 4) is used to control the frequency of the voltage-controlled multivibrator (IC1) as a function of the load on the output of the transformer (Ü) and, in addition, to produce an auxiliary voltage (UH) as the voltage supply for the control-pulse circuit (ST). While the DC/DC voltage converter is being switched on, the auxiliary voltage (UH) is produced via a separate starting circuit (AS) which operates only until the flyback converter is oscillating. <IMAGE>
