Title: Charging pulse release circuit for telephone exchange - has transmission unit accessed by facilities selection codes and pulses suppressed whilst instructions are dialled in
Inventor: VOIGT WOLFGANG
IPC: H04M15/10
Filed: 1980-05-20
Abstract: The telephone exchange circuitry is used to cancel charging pulses whilst a customer is accessing special facility equipment, e.g. in-coming call recorded announcement or alarm call equipment, and dialling instructions into the equipment. The instructions are dialled in by means of selected codes. When the special facility access codes are received by the subscriber's normal exchange line equipment (E) a 'blind' transmission unit (B) is also seized from a group of waiting units. The 'blind' unit suppresses the charging pulses whilst codes are being dialled into the special facilities equipment, and for a little longer according to the time delay (VZ) in the 'blind' unit's circuit, and restores the pulses afterwards. The 'blind' (B) unit may be connected in parallel or series with the special facilities unit. The exchange uses line-finder (LW) methods to seize a free unit (B) which has relay (R) self holding circuitry and (c) control wire earth holding.
Patent DE-3021535-A1 (DE)
Title: Accurate and rapid weighing method for small items - uses detector to analyse interference pattern for determining weight
Inventor: PRYOR TIMOTHY R
IPC: G01G9/00
Filed: 1980-06-07
Abstract: The weighing apparatus includes weigh members wich are movable in sequence in a continuous path. Each weigh member receives an item to be weighed and includes a member which is movable in response to the weight of the carried item. When an item to be weighed is deposited on a weigh member, the movable member moves in response to the weight and then "springs" back in an oscillating fashion. The weigh members, each carrying an item to be weighed, are rapidly moved in sequence along the continuous path to a weighing location and the time, is sufficient to substantially cease by the time that the weight member arrives at the weighing location. At the weighing location, light radiation is impinged upon a boundary edge of the movable member and a pattern of light radiation is provided which is characterised by the position to which it moved in response to the weight of the item carried by the weigh member. Diffraction waves from the boundary edges interact to form an interference pattern wich is characteristic of the position of the movable boundary edge relative to the fixed boundary edge. The pattern is analysed to determine the weight of an item borne by each respective weigh member.

Title: Appts. for detecting charged state of ion exchange material - in household machines by expanding sphere pressing against leaf spring
Inventor: DEISS ULRICH
IPC: B01J47/14
Filed: 1980-10-21
Abstract: A device for detecting the charged state of the ion exchange material of a water softening plant for dish-washing or washing machines operates on the principle of an expansion element in the ion exchanger, which expands according to the condition of the resin. The expansion element is a sphere, resting in a seating on a support; the top of the sphere bears against the underside of a leaf spring, having a strain gauge strip attached to it. Thus, as the sphere expands with the changing condition of the resin, the leaf spring is raised and can be used as an actuator for triggering a regenerating operation. Used for the ion exchange resin installations of dish washing and washing machines. The arrangement is simple and requires no sealing rings as in a preceding device operating on the piston-cylinder principle.

Title: Protection of coal dust against self-ignition in air - by coating particles with oil from oil from coal hydrogenation
Inventor: LUETTGER HANS
IPC: E21F5/18
Filed: 1980-12-22
Abstract: Coal dust or other fine coal is coated with oil from coal hydrogenation to protect it against uptake of atmospheric oxygen and eventual self-ignition. 3-6% of the whole oil or of a distillate fraction thereof is added to the coal, pref. during grinding. The softening point of the oil should be below the temp. of grinding. Used before storing or transporting the coal. The tendency of the dust to fly is reduced. The dust packs to a greater density (about 0.2 kg/cu dm greater), reducing transport and storage costs. Ignition by external sources is made easier by the rapid vaporisation of the oil.
Patent DE-3100507-A1 (DE)
Title: Vehicle brake system with hydrodynamic and friction brake
Inventor: CAPPELL ALEXANDER ING GRAD
IPC: B60T17/22
Filed: 1981-01-10
Abstract: In a vehicle brake system with a hydrodynamic brake and a mechanical friction brake, in which the hydrodynamic brake responds to a braking command and at the same time builds up a hydraulic feedback pressure, and in which the mechanical friction brake can be hydraulically actuated by way of a brake control valve (1), a differential control piston (3) is provided in the brake control valve, which is acted upon on the one side by an actuating pressure (pA) corresponding to the brake command and on the other side by a pressure corresponding to the feedback pressure of the hydrodynamic brake. When the actuating pressure (pA) predominates, the differential control piston (3) is shifted into an active position in which it opens a path for the application of a storage pressure to the friction brake. For indicating a reduced output or a failure of the hydrodynamic brake the brake control valve has a position sensor (30), which monitors the position of the differential control piston and if this piston is in the active position, delivers an indicator signal. If necessary a locking device can be provided which prevents activation of the indicator signal when the speed of the vehicle is less than a predetermined limit. The output of the position sensor (30) can be coupled to a timer element, which allows the indicator signal to give an effective indication only when it has persisted for a predetermined minimum time. The position sensor is advantageously a microswitch arranged on the body of the brake control valve, the actuating element of which switch extends into the displacement space (25) of the differential control piston (3) on the actuating pressure side. The position sensor may also be an inductive proximity switch, the sensing coil of which is arranged on the brake control valve so that its field range extends into the displacement space of the differential control piston on the actuating pressure side. In this way an operating malfunction of the hydrodynamic brake can be indicated to a driver by means of a simple pilot indicator. <IMAGE>
