Title: Article packaged in hot shrink sheet - supplied with double V folded edges gripped at all four corners
Inventor: WIKER KJELL A
IPC: B65B9/13
Filed: 1973-09-01
Abstract: An appts. for making a bag-shaped wrapping from hot-shrinking plastic sheet and applying it around an article to be packaged uses as the starting material a rolled up plastics tube in which the opposite flattened edges are pushed inwards to form a double V-fold. This plastic tube is fed onto and around the article to be packaged by means of four pairs of clamping and conveying belts, i.e., four belts on each side of the plastic tube. In a preferred arrangement, the still folded sheet is fed vertically downwards above the article and is then splayed outwards by having its four V-folds gripped each between a pair of endless belts, which first follow a horizontal path to splay and open out the plastic tube and then change to a vertical path to convey the tube downwards over and around the article to be packaged. A welding and cutting unit is pref. mounted just above the article so that the article leaves the apparatus clad in an upturned plastic bag.

Title: Capacitor films with very thin aluminium coatings, prodn. - using first coating of chromium, silver or titanium (alloy)
Inventor: EPPLE RICHARD DIPL PHYS DR
IPC: H01G4/008
Filed: 1973-11-29
Abstract: films for capacitors with Al film of min. thickness are produced by giving the film at first coating (I) of Cr, Ag or Ti or an alloy of at least two of these and then an Al coating (II) the thickness of (I) being 25-100% of that of (II) whilst the max. total thickness is 500A degrees. Pref. (I) is a 100A degrees Ag film and (II) a 200A degrees film. Ag, Pd and/or Rh coatings can be applied below (II). All these metal films pref. are deposited from the vapour phase, the films being narrower than the substrate film but extending to one edge of this, whilst the other edge pref. is stepped, so that the Al film is the narrowest. The widest metal film pref. consists of a poor conductor (Ti and/or Cr). The use of very thin Al film prevents the formation of holes (due to the presence of water and gas), so that capacitors with constant capacity and higher vol. capacity can be made.
Patent DE-2401858-A1 (DE)
Title: I.C. engine testing method - involves measurement of crankshaft angle between ignition and top dead centre, in first cylinder
Inventor: LINDENBERG MARTIN
IPC: F02B77/08
Filed: 1974-01-16
Abstract: When the engine runs, all time intervals between ignition and top dead centre of the cylinder as measured over a specified long period, added, and at least proportionately displayed. The ratio of the sum of the time intervals to the total measurement time corresponds to the crankshaft angle between ignition and top dead centre, and the pulses generated by a constant frequency oscillator are counted during the time interval between the ignition and top dead centre, and the total of the pulse count during the long period is displayed; a gate is opened by the ignition pulse, and closed by a pulse from a top dead centre pick up, so that oscillator pulses can reach the counter only when the gate is open.

Title: Friction brake for industrial purposes - uses fully lined double disc brake for low maintenance and easy cooling
Inventor: LANGENBECK GEORG
IPC: F16D65/28
Filed: 1974-02-14
Abstract: The brake is mounted on a stationary base plate. The plate carries an actuating mechanism, e.g. an electrohydraulic unit, or a solenoid magnet, acting via a lever onto a brake. A spring acts onto the lever, to regulate the brake force. The spring is pretensioned by adjustment of a rod, passing through a spring housing, and sealed by a lip seal. The brake may be pushed onto the second end of a motor shaft, or any other free shaft end. Alternately, it may be flanged to a coupling. The spring operates when the electromagnet is not energised. The spring pulls the level into a position to cause braking.

Patent DE-2433356-A1 (DE)
Title: Battery charge state monitoring unit - has automatic load disconnection at preset voltage level
Inventor: TILLMANN UDO
IPC: G01R31/36
Filed: 1974-07-11
Abstract: In rechargeable batteries, for example as used in motor vehicles, it is important that secondary loads do not discharge the battery to a level where insufficient energy remains for primary duties such as starting. An integrated circuit (IC) connected as a comparator has one input (A) connected to a signal proportional to battery terminal voltage and the other input (B) to a fixed reference. If the terminal voltage falls below the reference the integrated circuit gives an output signal to operate the relay coil (Rel) and trip off the load by means of a switch (S). As the circuit is always operational a load cannot be connected if the voltage is too low.

Title: Compensated storage heater control - has charge control cct responsive to mains voltage fluctuations for charge time regulation
Inventor: WILKE CHRISTIAN DIPL ING
IPC: G05D23/24
Filed: 1974-09-16
Abstract: A charge controller is regulated by a control signal from a charge control circuit. The control signal is varied in accordance with the respective mains voltage deviation from nominal value. As a result, the storage heater charging time is shortened or extended, so that the exact rated quantity of heat is stored at the charge end. The charge controller has two sensors so that the sensor relationship alters appropriately for both positive and negative fluctuations of mains voltage. The compensation dependent upon the outside temperature is so arranged that with positive mains voltage fluctuations with rising outside temperature the sensor relationship decreases and with negative fluctuations with rising temperature the relationship increases.

Title: Safety belt for vehicle for aircraft - has edges which have rounded profile to prevent clothing wear and injury in case of accident
Inventor: BERGER JOHANN
IPC: D03D11/00
Filed: 1974-10-01
Abstract: On at least one longitudinal edge (23), but preferably both, a length of piping (23, 7), or beading, is attached. This piping is in the form of a tube, its thickness when fixed being equal to the belth thickness; this allowing the use of the belt in standard reels. The tube is made of fabric (23.5), similar to that of the belt, but the weave being less compact and softer. Attachment of the piping is done by weaving into and over it, at the time of manufacture a tail (27.1) which is present on the piping for this purpose. The resulting belt has a homogenous appearance.
