Patent DE-2702713-A1 (DE)
Title: Control loop for pulsed control - uses error sign dependent drive channels for two state control elements
Inventor: SCHRADER UWE DIPL PHYS
IPC: G05D23/24
Filed: 1977-01-24
Abstract: A control loop for pulsed control has an input amplifier outputting the control error as deviation from a reference value to a control circuit varying the duty cycle of pulsed signal driving the two-state final control element so as to reduce the error. It is designed for efficient accurate control given any control problem. The circuit contains a pulsed signal source feeding a level shifting circuit which outputs two different biased periodic control signals lying either side of the reference value. These are input to separate comparators corresp. to error sign and driving associated two-state control elements.

Title: Shaft speed indicator device - has AC generator feeding frequency to voltage converter and stabiliser circuit giving reference voltage
Inventor: LEHMANN AXEL DIPL ING
IPC: G01P3/481
Filed: 1977-03-09
Abstract: An indicator device generates a voltage proportional to the instantaneous speed of a rotating shaft. It contains an a.c. generator and a voltage-to-frequency converter circuit. A rotating shaft (10) is coupled by means of a connecting member (11) to the generator (12). Connections (13) from the generator feed a frequency/voltage converter circuit (15) and a stabilising circuit (17). The generator gives an output current of which the frequency depends on the speed of rotation of the shaft and this is changed in the converter circuit to a speed-dependent voltage. The stabiliser circuit produces a DC output which serves as a reference voltage for the converter circuit.

Title: Tubular cooling element for a crystalliser - using pulsating internal pressure to deform its elastic walls removing crystal incrustations (OE 15.7.77)
Inventor: LOQUENZ HEINZ DIPL ING
IPC: D06B1/08
Filed: 1977-05-04
Abstract: A tubular cooling element is in two sections sepd. by a restrictor. It has elastic walls so that when coolant flows through, the greater press. in the section upstream of the restrictor increases the cross-section of that part of the tube above that of the downstream part. By periodic reversal of coolant flow the relative cross-sections of the two sections is interchanged. Used as cooling elements for soln. crystallisers e.g. for the crystallisation of MgSO3 from MgSO3-CaSO3-calcium sulphite solns. from the cellullose industry. Simple and inexpensive system for the avoidance of crystal incrustation on crystalliser cooling surfaces with resultant downtime for cleaning and loss of heat transfers provided.

Title: Gauge to measure small gaps - compares degree of penetration of two wedge shaped feelers of different angles
Inventor: PASQUINI ALFREDO
IPC: G01B5/00
Filed: 1977-06-13
Abstract: The gauge is for measuring the play between two components, especially that between a cam and an actuating rod in the valve control system of an IC engine. A body (1) carries two wedge shaped feelers (3B, 9A) with different wedge angles, one fixed to the body and the other sliding with a vernier gauge to read its position. The wedges are introduced into the gap until both wedges just fit between the opposing components, and the effective gap is then read off from the calibration of the vernier scale.

Title: Reverse interrogation circuit for local telephone exchanges - connects two telephone subscribers to common supply line
Inventor: DIRR JOSEF ING GRAD
IPC: H04Q3/62
Filed: 1977-06-20
Abstract: When a subscriber lifts his handset he occupies a call finder internal connection unit. An exchange arranged line selector register is then connected via a relay selector. On dialling the official code a free line to the internal connection unit is selected and the line selector register becomes free again. The connection to the called subscriber takes place by way of an internal dialogue. After registration of the same, the connection is made on the call finder internal connection unit. Two subscribers are thus connected with one supply. Previous exchange circuits permitted the reverse interrogation of a particular dialler which was controlled by a subscriber unit. This arrangement permits interrogation of a dialler at random.

Title: Quiet running suspended vertical centrifuge - with balancing hoops on outside of centrifugal housing
Inventor: ZEPPENFELD KURT DIPL ING
IPC: B04B9/14
Filed: 1978-01-20
Abstract: Centrifuge with a bowl on a vertical shaft has a housing which is attached by suspension rods to columns. The housing is surrounded by several hoops with sections of different weight. They are adjusted in such a way that the overall centre of gravity of the centrifuge remains in the central plane of the bowl. This improves the stability and quiet running characteristics of a centrifuge in spite of various filling degrees and to compensate for extra fittings (scrapers). The reduced pitching motion results in a more gentle treatment of the suspension.

Title: Washing machine water softener brine monitor - has overflow in softening unit level with filler
Inventor: BERTSCH KARL DIPL ING
IPC: A47L15/42
Filed: 1978-05-29
Abstract: The system to monitor and indicate the concn. of brine in the regenerated saline soln. in the softening unit for a clothes or dishes washing machine has the outlet for the brine located directly near the lid, pref. at the level of the upper edge of the filling tube. The float is held below this level.

There is an overflow sleeve for the brine outlet in the filling tube and spaced from it so that the overflow edge incorporates the upper edge of the filler. There are vertical webs to maintain the gap between the overflow and filler, so that they form separate overflow channels leading to a common collection zone.

Title: Skin-pricking, self-sealing catheter end section - for intra-arterial infusion, comprises silicone rubber tube turned inside out to reduce circumferential stretch tension
Inventor: KRAMANN BERNHARD DR MED
IPC: A61M39/02
Filed: 1978-07-12
Abstract: Self-sealing, skin-piercing, catheter end piece is used for relatively long-term intra-arterial infusion of therapeutic substances into a patient's diseased organ(s). The catheter end piece comprises a rubber (specifically silicone or silicone rubber) tube which has been "turned over" so that its initial outer surface becomes its inner surface and vice versa. This results in substantial reduction of elongation tension of the inner circumference thus ensuring tight fit in the perforation of the patient's skin when the same is pierced, with consequent less risk of infection through the gap between skin perforation and catheter wall. This is esp. important since the claimed article is intended for use in conditions where a patient's resistance to infection is low in any case.

Title: Power generator utilising natural energy - has vessel containing fluid descending by gravity and fluid rising by geothermal convection
Inventor: THAMS HANS
IPC: F03G3/00
Filed: 1978-08-30
Abstract: A deep shaft (10) is bored into the soil. A hollow container (12) with a rod (14) can move up and down the shaft. It is filled at the top with a liquid of high specific weight and low specific heat capacity. The weight causes the container to fall down. It pulls the rod (14) with it and this drives a generator. At the bottom of the shaft the high temperature in the soil evaporates the liquid and the vapour rises through a bore (15) in the rod (14). The container is then pulled up mechanically with the consumption of less energy than was generated by its fall.
