Title: Bottle unwrapping machine with rotating cage - has transfer frame for moving containers to filling station after unwrapping
Inventor: BRAUN ALFRED
IPC: B65B55/04
Filed: 1978-03-31
Abstract: An unwrapping installation is used to remove the sterile overwrap foil which protects a number of empty containers, such as bottles, during transport. A horizontal, cylindrical cage (2) has an axial pivot along one side so that it can be opened. Two parallel locating frames (15) in the centre of the cage (2) will hold the wrapped container pack. Before closing the cage, the foil is cut with a knife and peeled back to the sides of the containers. After closing and rotating the cage through 180 deg., it is opened again to allow the final removal of the overwrap foil.
Patent DE-2816919-A1 (DE)
Inventor: MEIER ALOIS
IPC: D06F57/06
Filed: 1978-04-19
Abstract: There is at least one vertical rectangular frame (101) which can be dismantled.

Patent DE-2821990-A1 (DE)
Inventor: CELIO TINO DR ING
IPC: G05D11/13
Filed: 1978-05-19
Abstract: Two valves (4, 5), which are each connected in series with a flowmeter/pulse generator (6, 7) in the feed pipes for the two media to be metered, are triggered by an electronic control system. The main components of the control system are an upward and a downward meter (16, 15) which are each connected to one of the flowmeter/pulse generators (6, 7) and count pulses generated by the latter in proportion to the quantity. When a metering process is initiated, the two meters are set at the same starting number, which can be input by means of a preselector (9) and corresponds to the percentage accounted for by one of the two components to be metered. When the two meters reach their zero positions, the valve associated with them in each case is closed. Designing the control system with an upward and a downward meter permits metering to be virtually simultaneous while keeping the outlay on circuitry relatively modest. <IMAGE>

Title: Lubricating technique for piston engine cylinder surfaces - protects surfaces exposed to wear, and has metered injection with variable interval between cycles
Inventor: WIENE POUL EMIL
IPC: F01M1/22
Filed: 1978-06-23
Abstract: The lubricating technique for wear-exposed surfaces of piston engine cylinders is based on the metered injection of lubricant through openings in the cylinder wall. Each cylinder has a separate supply line from the pump, embodying a unit which determines timing and duration of injection, triggered by a cylinder-mounted sensor. Each set of openings is fed through a metering valve via a flow indicator. Flywheel driven electric/electronic revolution counters respectively endorse and suppress the triggering signal to introduce a gap after every two (or more) injections. The counters can be programmed to vary the gap with running conditions.

Patent DE-2831145-A1 (DE)
Title: Subscriber circuit with AF pushbutton selection for PBX - has special-facility buttons each used twice depending on whether handset is lifted or not
Inventor: MERSMANN FRIEDHELM ING GRAD
IPC: H04M1/53
Filed: 1978-07-15
Abstract: A pulse generator (IS) is controlled either by special-facility pushbuttons (ST) or from the normal selection keyboard (WT). The special-facility buttons allow various additional facilities like enquiry calls, rerouting, intervention, conferencing etc. to be activated by pressing the appropriate special-facility button - which causes an appropriate sequence of pulses to be generated. The special-facility buttons are arranged so that special facilities can be activated even without lifting the handset. Normally an even number of pulses is generated when a button is pressed. With the handset not lifted whichever is the last pulse is not generated by the subsequent and continuous loop-break so that an odd number of pulses is produced. This odd number activates those special facilities appropriate to an unlifted handset. The special-facility buttons can be used twice e.g. for direct connections to an attendants set in the private branch exchange system or to an extension. The user only has to operate the button for the wanted special detected by a centralised sampling device by counting. Since the pulses generated are temporarily independent of the user's behaviour, the centralised detector can be set to fixed values.

Title: System for burning oil-coal dust mixt. - feed pasty mixt. to combustion chamber and atomises it by hot air prior to combustion
Inventor: MAYRHOFER OTTO DIPL ING
IPC: F23C1/10
Filed: 1978-12-15
Abstract: The system for burning an oil and coal-dust mixture uses a vertical-walled combustion chamber (1) with a travelling grate across the bottom (3) fed with oil-coal paste suspension. A vertical partition (7) ending above the grate divides this chamber into a combustion space (2b) and an air space (2a). Air from the latter, preheated, pref. regeneratively, passes through the grate and vaporises the liquid part of the paste. A casing (9) under the chamber deflects the air-vapour mixture flow back up through the grate, creating a powder-cloud from the solid part in the combustion space.

Title: Curtain tape with adjustable heading depth - has vertical rows of pockets in tape for curtain hooks
Inventor: KOEHNE FRANZ
IPC: A47H13/16
Filed: 1979-01-12
Abstract: The curtain tape is made fo a fabric having a certain pliability and containing gathering cords and pockets (12-17) wherein the latter are used to hold the curtain hooks. So that the epth of the curtain heading can be adjusted to cover the curtain rail the pockers are set in vertical rows allowing the required pocket to be chosen for the hook. The pockers can be formed by full-length stable individual threads which are woven into the tape. The pockets (12-17) and the loops (11) of the gathering threads (6-9) can be arranged in alteration, seen in the horizontal direction (30) of the tape. One pocket can be set between two gathering threads, seen in the vertical direction (31) of the tape. The tapes of the pockets now run at right angles to the gathering threads which serves as an additional reinforcement for the tape over its entire length.
Patent DE-2903362-A1 (DE)
Title: Electromagnetic air brake for rotary machine - combines flat and plunger armature attraction effects with electromagnet excitation to brake shaft
Inventor: ROPELIUS KLAUS DIPL ING
IPC: F16D59/02
Filed: 1979-01-29
Abstract: A brake lifting electromagnet for rotary electrical machines has a magnetic iron core (1) with an embedded exciter coil (3) firmly fixed in the motor casing (6). The armature (2) revolves with the motor shaft (4) and is axially displaceable. A spring (5) moves the armature away when the electromagnet is de-energised and applies the friction brake. When the electromagnet is switched ON and pulls the armature up to a stop (7), the vertical faces cause an attraction by the flat armature principle, and the horizontal faces by the plunger armature principle. The result is a balanced force of attraction as a function of the stroke of 10-20 mm with reduced excitation power.

Title: Ducting cable through walls - using barrel anchored in concrete wall with end caps and reducing cable-support collars
Inventor: LANGMATZ HANS
IPC: H02G3/22
Filed: 1979-03-07
Abstract: Grommet and collar equipment is for feeding electrical cables through a wall.

Title: TV receiver remote control with frequency stabiliser - uses one oscillator and discriminator in control loop with another as reference
Inventor: MALINOWSKI CHRISTOPH DR ING
IPC: G08C19/12
Filed: 1979-10-15
Abstract: A remote controller, e.g. for a TV receiver, sends instructions in the form of a frequency, different frequencies being used for different functions. The frequency is generated by a voltage controlled oscillator, which drives a frequency discriminator. The discriminator output is compared with a reference voltage and the difference controls the oscillator. This forms a control loop which stabilises the frequency against temperature and supply voltage variation. Variation of the discriminator is compensated by deriving the reference voltage from a second discriminator driven by a fixed frequency oscillator. The two discriminators are of identical construction, pref. integrated on the same chip. Different frequencies are obtained by changing the reference voltage using a resistance divider and/or an amplifier. Frequency modulation may be generated by superimposing AC on the reference.
