Title: Frequency shifting of pseudo-ternary coded digital signals - involves leaving O bits unchanged, but 1 bits are replaced by groups of alternating pulses
Inventor: POSPISCHIL REGINHARD DR ING
IPC: H04L25/49
Filed: 1977-12-13
Abstract: The signal is in an AMI or modified AMI code, and the frequency is shifted by an integral multiple of the bit repetition frequency. Pulses representing the "O" bits in the signal to be modified remain unchanged, while its pulses representing the "1" bits are replaced by a group of odd number n of alternating pulses. Polarity of the first pulse in the group corresponds to that of the pulse being replaced. This results in the shifting of the main energy range by (n-1)-times half the bit repetition frequency, and the output signal pulse repetition frequency is n-times the input signal frequency.

Title: Metal casting in precise doses - by coordinated motions of ladle, jib and slewing arm
Inventor: EYKELEN HANS
IPC: B22D39/02
Filed: 1978-03-25
Abstract: A device to cast precisely metered amts. of a metal melt from a crucible into casting machines consists of a jib which carries the casting ladle and can be swivelled in the horizontal plane on the pivot of a slewing arm. The jib movements and the motorised inclination of the ladle are coordinated with the tipping motion of the casting machines by electronic control units. This can be used to cast even small amts. of metal in a regular cycle. The pouring spout of the ladle is always kept in the exact position relative to the mould to be charged and the impact velocity of the poured metal is minimised.

Title: Electrostatic dust separator - with barrier walls and overlapping baffle plates in dust collection bunker
Inventor: HERKLOTZ HELMUT DIPL ING
IPC: B03C3/88
Filed: 1978-10-10
Abstract: An electrostatic dust separator consists of a housing with suspended vertical discharge and precipitation electrodes and with a dust collection bunker belowthem. The dust-laden gases flow through the housing in a horizontal direction. Barrier walls in the dust collection bunker at right angles to the gas flow are complemented by baffle plates between the bottom of the electrode section and the top of the barrier walls, pref. overlapping the latter slightly. The baffle plates are suspended from a part of the pptn. electrode, such as the knocker mechanism which keeps them free of dust. This prevents any side stream from bypassing the electrode section via the dust collection bunker and improves the dust collection performance of the electrostatic dust separator without interfering with the knocking, the dust flow or any necessity for high field strengths.

Patent DE-2845972-A1 (DE)
Title: Liquid crystal display with high contrast - which is achieved using dye to make excited crystal white against normal dark background
Inventor: TISCHER MANFRED DIPL PHYS
IPC: G09F9/30
Filed: 1978-10-21
Abstract: The liquid crystal display consists of a liquid crystal (1) between two glass plates (2). The insides of the glass plates have transparent electrodes (e.g. evaporated tin oxide). A light guide (3) is located in the outside of one glass plate between it and the rear light source (4). The light guide consists of black laminae (5). These laminae are visible from the front when no voltage is applied to the liquid crystal. When a voltage is applied light from the rear source is scattered inside the crystal to give a light display against a dark background. The same applies if the light is incident from the front instead of from the rear. The liquid crystal contains a dye that forms white with the crystal's own colouring when the crystal is excited. Alternatively a coloured light source of coloured front glass may be used to attain the same result.

Title: Cylinder for printing machine with protective coating - corresp. to polyamide obtained by casting on laurin-lactam monomer
Inventor: HANDTMANN ARTHUR ING GRAD
IPC: B41N7/06
Filed: 1978-12-12
Abstract: The protective coating on a colour or friction cylinder for a printing machine consists of cast polyamide. This is obtd. by casting on laurin-lactam monomer which is activated by anionic polymerisation. The polyamide is applied to the central zone of the shaft between the journals and forming a single piece with them and having near enough the same diameter. This simplifies the process by which protective surfacings of the 'RISLAN' (RTM), (polyamide eleven) type are applied so that whilst avoiding the great expense of known methods. A protective coating corresp. at least to the quality of the 'RISLAN' coating can be appied, at least between the journals of the shaft.

Title: Assembly fitment for fold-away kitchen appliances - is freely movable adapting to any height work surface via swivel arm
IPC: A47B77/12
Filed: 1979-02-06
Abstract: The all-purpose slicer or other kichen appliance can be swivelled from a storage position up into a position of use. It is set on a support which is connected for height adjustment to the swivel arm and is mounted in the arm so that it is free of rotation but can be displaced with play on all sides. The swivel arm is used for swivel mounting the appliance in the holder. The assembly unit for the appliance is now freely movable while connected to the swivel arm so that it can be extended beyond the work top, pushed back over the worktop and then lowered onto it. This allows for the various differences in height of different kitchen fitments to be compensated for. This also ensures that the appliance is not pushed back directly on the worktop which would cause scratches or other damage.
Patent DE-2908154-A1 (DE)
Inventor: FOERSTER RUDOLF
IPC: B02C17/16
Filed: 1979-03-02
Abstract: In order to keep the material for milling which is filled into the milling space (20) away from the shaft bearing (28) and in order to separate off the milling space (20) from the discharge chamber (54) so that only material for milling but no grinding bodies located in the milling space can pass into the discharge chamber (54), a rotating ring (66) is constructed as separating ring and as sliding ring and is part both of a separating device and of a sliding ring seal. This ring (66) forms at the same time the radially inner limitation of the discharge chamber (54) and interacts with a fixed separating ring (52). By means of the combination of the otherwise customary two rotating rings to form a single ring, the production and maintenance costs of the separating device and of the sliding ring seal can be reduced. <IMAGE>

Title: Safety bar screen for power stations - produces warning signal of any interference attempt by frogmen
Inventor: MARZLUF WERNER ING GRAD
IPC: G08B13/12
Filed: 1979-06-26
Abstract: Safety bar screen in the inlet or outlet channels of power stations, specially of nuclear power stations, is fitted with devices to prevent the entry of enemy frogmen or terrorists. The bars of the screen are hollow and a conductive element such as a wire or a strip is stretched across its length. If attempts are made to bend or destroy a bar, the normally insulated element is connected to earth by contact with the bar wall or by the entering water and an alarm signal is produced. This gives an instant warning to the central control station that intruders are attempting to gain access to a power station.

Title: Multi-output transistor frequency converter - has measuring circuit coupled to additional winding of power transformer for controlling transistor switching
Inventor: KUPKA DETLEF ING GRAD
IPC: H02M3/335
Filed: 1979-07-25
Abstract: The converter provides several stabilised output voltages (UIT Ux), with an auxiliary winding (V) of the power transformer supplying a voltage proportional to the voltage across the secondary windings (II-IV) to a measuring circuit (M) adjusting the switching of the switching transistor (TS). The measuring circuit (M) has a capacitor (C3) which is charged and discharged via equal ohmic resistances (R1,R2). The charging resistance (R1) is bridged by a diode (D3) during discharging. The measured voltage is obtained from the capacitor (C3) via a voltage divider resistance (R3) with a high ohmic value relative to the charging and discharging resistors (R1,R2). The measured voltage is then fed via a regulating amplifier (RV) to a A/D converter providing the control signal for the switching transistor (TS).
