Title: Ringing-current and loop-current supply for telephony - has amplifier connected between incoming and outgoing line amplifiers to reduce echo and side-tone
Inventor: DRAGOTINOV ALEXANDER DIPL ING
IPC: H04M19/00
Filed: 1978-08-01
Abstract: The supply can be fabricated as a monolithic component and is intended for PCN telephone exchange systems. Controlled current sources form part of a hybrid circuit. The loop current on the two wire side of the hybrid is modulated via two current sources by the output of the incoming amplifier on the fair wire side. Signals from the 2-wire side are transmitted to the outgoing line on the 4-wire side by an outgoing amplifier. A third amplifier is connected between the incoming and outgoing terminals on the 4-wire side for side tone and echo attenuation.

Title: Minimum altitude control and display for aircraft - uses on-board computer for automatic monitoring of actual altitude for comparison with minimum permissible Valve
Inventor: BRAME FRANK HERBERT
IPC: G01C5/00
Filed: 1979-02-26
Abstract: An on-b oard control and display computer system for aircraft provides monitoring of the minimum permissible altitude at points along a specified flight path. Co-ordinate measuring systems (100) provide instantaneous evaluation velocity and flight path that are correlated (16a) with data held in a memory relating to minimum altitude. An on board computer (22) processes Pitot tube (24, 26) inputs to provide altitude values that are compared (28) with the correlated values. If the minimum altitude condition at a point of the reference grid are in danger of being approached, a warning signal generator (30) is triggered to activate a display (34). At the same time an on-board computer (38) evaluates the required corrective action.

Title: Encapsulating of objects in hermetically sealed containers - stamped from powdered thermosetting epoxy! resin and melted to seal
Inventor: SILLNER GEORG RUDOLF
IPC: B29C67/04
Filed: 1979-04-20
Abstract: A stamping from a powdered thermoplastic material, esp. an epoxy resin with a thermally activated hardener, in which there is >=1 suitably dimensioned recess, is used to enclose an object in a hermetically sealed envelope. When the object has been inserted, the stamping is exposed to heat, possibly whilst being rotated, so that its material melts together and encloses the object completely. The process is partic. applicable to the encapsulating of electronic elements from which conductors project. Where these project axially, the stamping may be a tube, which melts into a pearl. With conductors extending parallel or radially a box and suitable covered with holes may be used.

Title: Button drill bit - with specified undercut at bottom of blind holes preventing fatigue cracks
Inventor: LUMEN KARL LENNART GOESTA
IPC: E21B10/56
Filed: 1979-05-28
Abstract: Parent Patent No. 2807353 described a rock bit of the button type in which the cemented carbide buttons are inserted in the bit body through blind holes with a radiused undercut at the bottom. The ratio of the distance d between the largest undercut and the hole dia. D, on the one hand, and the hole dia. on the other hand, is pref. within the range of 1:5 and 1:100 (1:35). Experience has shown that this prevents cracks in the supporting bit body and results in a longer service life of the drilling bit.
Patent DE-2929206-A1 (DE)
Title: Spool carrier for magnetic cored coils - has two identical halves with locating pins for easy assembly over core
Inventor: BOYE JAN DIPL ING DR ING
IPC: H01F41/08
Filed: 1979-07-19
Abstract: The spool carrier (7) consists of two halves (8 and 9) which have at the ends of their mating surfaces, centering pins (109 and corresponding holes (11) so that when the two halves are put together, the pins (10) enter the holes (11) and ensure an exact fit. Since the two halves (8,9) are identical, mating them is an easy matter and they can be secured by adhesive or a band wrapped around the centre. The two halves (8,9) have flanges (12,13) each end which limit the extent of the winding, and can be ridged or toothed on their edges, so that a reliable drive can be obtained when winding the coil. The spool carrier (7) is for use where it is required that the coil has a magnetic core, and because of the shape of the core, e.g. three limbed. A one piece carrier cannot be used. After assembling the carrier (7) on the core, a winding machine can wind the wire onto it.
Patent DE-2934800-A1 (DE)
Title: Dual position IC engine - has mechanism coupling pistons to shaft over part of stroke with free motion over remainder
Inventor: ANDRASCH HANS-JOACHIM
IPC: F01C1/073
Filed: 1979-08-29
Abstract: The engine has a toroidal cylinder (2) round a shaft (4). Two discs (5,5') loose on the shaft carry pistons (6,6') in the form of arcs in the cylinder. A gear train (18,17,15,14) with a reduction gearbox (16) from the shaft rotates a cam (13) at the end of the shaft. This moves a plunger (7) axially inside the shaft. The plunger has tapered recesses (9,9') which push pins (10) in and out of slots in the discs. This couples the discs to the shaft between ignition and the end of compression. Arms (19,19') from the shaft into slots in the discs prevent reverse rotation over the rest of the stroke.

Title: Pneumatically operated vice assembly - has moving jaw supported on shaft with pinions engaging toothed racks
IPC: B25B1/18
Filed: 1979-09-19
Abstract: The vice used for securely clamping a workpiece (41) has a fixed jaw (12) and a moving jaw (14). The moving jaw (14) is mounted on a shaft (15) with pinions (16) which roll on toothed racks (13). The outer end of the shaft (15) supports two pneumatic cylinders. The jaw (14) is pushed by hand until it abuts against the workpiece (41). The outer cylinder (39) is then actuated and operates a brake which locks the shaft (15) to the plate (23). Actuation of the inner cylinder (29) tends to rotate the shaft (15) so that the jaw (14) is pressed hard against the workpiece.
Patent DE-2941738-A1 (DE)
Title: Superhet receiver with VCO - tuned using signal derived from digital expression of difference signal from mixer
Inventor: HENZE WERNER
IPC: H03J7/06
Filed: 1979-10-16
Abstract: The receiver has a mixer forming a difference signal from the IF frequency and subcarrier. A capacitor is charged or discharged by switching to a charging or discharging source and the resulting voltage across it is used as tuning voltage for a voltage controlled oscillator. The period of the difference signal is expressed in digital form using a counter and a first memory. The output of the first memory is passed to a comparator where it is compared with a reference. When the digital period exceeds the reference, one of the two switches is closed for a given time.

Title: Watercraft anchor raising unit - has stock-and-shackle assembly movable to fluke-end of shaft
Inventor: KLATT EBERHARD
IPC: B63B21/46
Filed: 1979-11-02
Abstract: The anchor for all types of watercraft, which can be raised without using brute force, has flukes pivoted transversely inside one end of a shaft in the form of a very elongated loop. A stirrup through this loop carries the stock, coplanar with the flukes, supported by springs pressing it towards the shaft. The stock carries the shackle. An outwards-pointing spike on the shaft-end remote from the flukes engages a recess in the stock when there is no load on the anchor. Loading breaks this connection so that the stirrup assembly can be pulled to the shaft's other end.
