Title: Inductance ballast coil for discharge lamps - core consists of two sets of stacked plates
Inventor: DALICHO ADOLF
IPC: H01F41/04
Filed: 1973-10-01
Abstract: The two sets of stacked ferrous plates, lying transverse to the longitudinal axis of the coil are held together by a surrounding metal band, such that the core has two winding apertures, either side of a central arm (822) with a rectangular winding (1) passing through the apertures. This is insulated by an insulating band (2) surrounding the central arm (822), with its longitudinal edges folded over the winding at the interior of the core. At least at the front, the centre limb of an I shaped head piece (3.3') formed of an insulating material, is located between the central arm (822) of the core and the insulating band (2). The position of the head piece (3.3') relative to the core, is such that the two cross limbs of the former extend in the longitudinal direction of the coil above the ends of the winding (11, 12) extending beyond the core, at least one cross limb carrying two contacts.

Title: Yarn winding device forming cross wound package - tensioner between bobbin and piecing up device ensures correct tension after piecing up
Inventor: ROHNER JOACHIM
IPC: B65H54/22
Filed: 1974-01-29
Abstract: A yarn winding device is fed from a supply with yarn which passes through pref. a main tensioner and is wond onto a take-up bobbin to provide a cross-wound package, the yarn pref. being guided onto the package by a helically grooved guide roll. When a break occurs or the trailing end of a yarn from one supply is to be joined to yarn from another supply, the ends of yarn are pieced up by a piecing up device. An auxiliary tensioning device is provided between the package and the piecing up device to tension the yarn as winding re-commences. No slack is allowed in the yarn after piecing up thereby ensuring a correct layer of yarn windings on the package.

Title: Opening and closing mechanism for doors etc. - has solenoid brake system acting directly on motor rotor
Inventor: SCHOELER GUENTER
IPC: E05F15/619
Filed: 1974-02-02
Abstract: The mechanism used for opening and closing of lighting unit covers, windows or doors has an actuating rod powered by a geared low power electric motor. The actuating drive for the panels has a rack and pinion drive and the actuation is braked when the motor is switched off by the trake. The rack is driven by the pinion which is coupled directly to the motor shaft. The rack in turn forms part of the actuating rod. The brake is a solenoid brake whose energised winding is connected in parallel to the motor winding. The solenoid actuated, spring-loaded braking plug engages directly with the slots of the motor rotor. The plug can be replaced by a brake shoe. This mechanism is compact owing to direct connections between the actuation motor, brake and driving rack and pinion.

Title: Garbage containers emptying appts - has arms for lifting and tipping of containers fitted with lockable jaws
Inventor: RIES GEB GOSSRAI
IPC: B65F3/02
Filed: 1974-04-25
Abstract: Two arms are spaced apart and hydraulically or pneumatically pivoted in a vertical plane. The top free end of each arm is fitted with a claw engaging a hand grip or a stub shaft on the side wall of the container. The claw is formed by two jaws of which the bottom one rigidly attached to the arm end is shaped to provide support for the attachment on the container wall. The top jaw is pivotably mounted on the arm end and in its closed bottom position prevents the container attachment leaving its location on the bottom jaw. During movement of the arm to engage the container attachment the top jaw swings upwards in an open position and during lifting and tipping swings downwards to secure the container attachment on the bottom jaw and is at the same time automatically locked in position.

Title: Detector for bugging senders - signals directly collected by microphone are correlated with demodulated LF signal from receiver
Inventor: PFAFF KLAUS DR ING
IPC: H04K3/00
Filed: 1974-06-12
Abstract: The correlation factor between signals directly picked-up by the microphone and the signal from the receiver is displayed by, e.g. a meter, and when a certain threshold is exceeded, an alarm is tripped. The cross correlation is carried out simultaneously for propagation time differences considered as probable, but at least for in-phase and opposite phase relations of correlated signals. The receiver is continuously tuned like a wobbled receiver, and the wobbling process is stopped when the correlation factor exceeds a specified threshold. The h.f. and i.f. portion (2) feeds the demodulation stage (3) from which a l.f. signal is led to a mixer (4). A low pass filter (8) filters the output before it reaches the indicator (9).
Patent DE-2431050-A1 (DE)
Title: Thermal disinfection of hospital or abattoir effluent - solids septd. first by screening
IPC: C02F1/02
Filed: 1974-06-28
Abstract: The thermal disinfection of effluents from hospitals or abattoris consists of a first stage in which a solids fraction is sepd. by screening from a liq-solids fraction with solids of under 2 mm particle size. The former is thermally disinfected and the latter is freed from solids down to an 0.3 mm size which are added to the solids fraction circuit. The remaining liq. fraction is preheated in a counterflow with the sterilized hot water from the final steam-operated sterilizer. This saves the necessity for a disintegrator which easily clogs and is damaged by entrained metal. Clogging of the heat exchangers by fibrous components is also eliminated.

The protuberances are rectangular in shape, and form soil-compartments between them. The plate is placed on the ground made flat by means of sand in the hollows. Where vehicles drive over the turf, a compacted gravel foundation is recommended. Preferably the protuberances are joined to each other by two sets of ridges and each protuberance in more preferred designs is either an octagon or a circle in horizontal cross-section.

Title: Light extrusion head for pipes, tubes and hollow profiles - ensures absolutely seamless and homogeneous surfaces
Inventor: HANSLIK WILHELM
IPC: B29C48/09
Filed: 1974-10-03
Abstract: An extrusion head for producing pipes, tubes and similar hollow profiles of synthetic matl., esp. of thermoplastics, in worm extruder presses, has a hollow cylindrical housing in which an arbor is positioned, and two gps. of buttress strips offset axially relatively to each other holding the arbor and dividing the channel formed by the extrusion housing and the arbor into separate passages. For preference the distance between the first and the last gp. of buttress strips is three to five times the figure for the outside dia. of the extrusion channel. Between the two gps. of strips, the outside dia. of the channel remains constant, whilst, in this zone, the arbor is set down in dia. Gives the same output with a much lighter and smaller extrusion head and ensures the complete and homogeneous melting together again of the separate streams created by the buttress strips.
