IPC: G03B27/46
Filed: 1978-03-09
Abstract: Installed in a single cabinet-like housing (10) are optical means for imaging an original picture (16) which is to be duplicated on a photographic colour picture reversal paper, an illuminating device for illuminating the original picture, a developing device for automatic reversal development of the exposed paper, and a drying device for the developed reversal paper. The developing device is designed for individual development of each of the individual duplicates. Arranged on one and the same front side of the cabinet-like housing are a transparent bearing plate (15) for bearing the original picture (16) which is to be duplicated and a dispensing opening (18) for the finished duplicate as well as all the operating members (17, 22, 24) required for starting up the device. The device permits economical and rapid production of individual colour picture duplicates in arbitrary time intervals, the original pictures possibly being photographic colour pictures. <IMAGE>

Title: Function control system for private branch telephone exchange - uniformly codes data for exchanging between different parts of exchange
Inventor: FRAAS WOLFGANG ING GRAD
IPC: H04Q3/545
Filed: 1978-04-14
Abstract: The function control arranges the data arriving and leaving central stations accoding to destinations for internal and external connecting circuits.

Title: Infeed for cylindrical workpieces - uses large spiral spring placed over rollers rotating in same direction
Inventor: MOELDERS JOHANN
IPC: B24C3/18
Filed: 1978-06-19
Abstract: The infeed arrangement is used, e.g. for passing cylindrical workpieces through a shot blasting machine. The workpieces are supported on two rollers which both rotate in the same direction and impart a rotating movement to the workpieces. Traverse of the workpieces through the machine is achieved by means of a large diameter spiral spring, which is mounted over the rollers. The pitch of the spring is such that one workpiece fits between two coils. When the spring is roated by the rollers, the workpieces move along the spring.

Title: Ion implantation in semiconductors - includes heat treating by intensive optical irradiation esp. laser beam
Inventor: SCHAUMBURG HANNO DR
IPC: H01L21/285
Filed: 1978-08-30
Abstract: Semiconductor devices are produced by ion implantation into a principal surface of a substrate in which the other principal surface has already been doped by epitaxial growth or ion implantation. The subsequent ion implantation is completed by a heat treatment through directing an intensive optical radiation (laser beam) on the surface. This cures the lattice dislocations caused by the ion implantation and helps to diffuse the implanted atoms in the substrate.

Title: Automatic clearance adjuster for two shoe drum brake - has reduced spring force to overcome on actuation of brake
Inventor: SCHROETER HANS O
IPC: F16D51/48
Filed: 1979-01-11
Abstract: Pressure blocks (8, 9) engage the shoes (2, 3) and are carried by an internally threaded ratchet sleeve (10). A pawl lever (11) carries a pawl (18) projecting through aperture (20) in housing (12) of sleeve to engage sleeve ratchet teeth. Control lever (7) coupled to shoe (2) retracts the pawl lever against action of tension spring (14) each time brake is applied. Spring (14) rotates sleeve (10) through one tooth pitch when brake is released if excessive clearance exits. Spring anchorage (13) on housing (1a) is nearer drum circumference than lever (11) fulcrum (17) so spring acts both to rotate lever (11) in its own plane and to pivot lever (11) down into resilient engagement with ratchet teeth.

Title: Binary to pseudo-ternary code converting circuit - has load input of shift register connected to coincidence gate outputs and to multi-switch via delay element
Inventor: TROOST MARCEL ABRAHAM DIPL ING
IPC: H04L25/49
Filed: 1979-07-11
Abstract: Telecommunications circuitry is esp. for telephone exchanges in which sequential binary signals are transmitted in pseudo-ternary form form. The binary signals are fed to a shift register for intermeW intermediate storage. The signals are pulse controlled as they pass through the register and are supplied to a multi switch for conversion to pseudo-ternary signals. The multi switch re-delivers the logic one binary signals with alternating polarity and the logic null unchanged. The outputs of the shift register are separately coupled to the inputs of a coincidence gate. The latter monitors the binary signals entered into the shift register for re-delivering as a continuous series of n+1 binary signals of the opposite type-one or null, except for the last series. A binary signal of the same type-one or null- is formed instead and stored in the corresponding position in the register.

Title: Hydrofoil keel of sailing boat - produces downwardly directed stabilising forces on hull using hydrofoil surfaces to replace ballast
Inventor: SALMINEN K REIJO
IPC: B63B3/38
Filed: 1979-09-13
Abstract: The keep incorporates a horizontally and longitudinally extending hydrofoil which produces a vertically downward force on the hull. When the boat is heeled over, the force acts through the e.g. of the boat to generate a righting moment. This counteracts the wind force tending to capsize the boat. A lateral force component also opposes the wind force to reduce the angle of yaw of the boat as it moves through the water.
Patent DE-2939217-A1 (DE)
Title: Telephone bell with clapper loosely coupled to armature - has rod in slot allowing loudness adjustment but not silent working
Inventor: ANTON HORST
IPC: G10K1/064
Filed: 1979-09-27
Abstract: The armature (8) of a telephone bell rocks when ringing current energises the solenoid (7). A lever (11), attached to the armature, has a pin (25) at its far end which engages in a longitudinal slot (17) in the clapper (18). The clapper lies between the two bells (2,3) and is pivoted on an eccentric (13) on the loudness control wheel (13). Turning the wheel moves the clapper towards or away from the bells and so varies the loudness of the ring. In the extreme 'silent' position, the clapper does not strike the bells at all, but there is still sound from the pole pieces (9,10). Since the armature lever is loosely coupled to the clapper by the pin and slot, there is no risk that incorrect adjustment will prevent armature movement.

Title: Unstable laser resonator of variable magnification - has optical elements with cylindrical surfaces placed between two spherical mirrors to create light path
Inventor: HOFFMANN PETER DIPL PHYS
IPC: H01S3/081

Abstract: Two spherical mirrors are used to generate a collimated output beam with non-rotational symmetrical magnification. At least two more optical elements (2,3) are positioned between the spherical mirrors (1,4). Each element has a cylindrical surface and their cylinder axes are at right angles to each other. The optical elements (2,3) can be mirrors or lenses. In the latter case, at least one of the lenses can also serve as a window for the container of the active medium. One or more of the light paths (9,10,11) can be lengthened by inserting one or more planar mirrors to effect further crossings of the light path(s).

Title: Coal briquette prodn. by pressing in box mould - with progressively decreasing rate of compression
Inventor: STRUCK CARL-HEINZ DIPL CHEM DR
IPC: C10B45/02
Filed: 1980-01-26
Abstract: Prodn. of coal briquettes for use in coke ovens is carried out by compressing the coal in a box mould having elongated rigid side-walls, at least one of which moves inwards under applied pressure, with the improvement that the rate of advance of the side-wall decreases during the compression operation. Pref. the rate of advance is pref. initially 2-4 mm/sec. gradually decreasing to a final value of 0.1-0.2 mm/sec. The decrease in the rate of advance compensates for the normally occurring decrease in deep-seated compaction, so that adequate compaction can be achieved in acceptable pressing times.
