Title: Sectioned sliding ladder drop-hook - as lever with arm on rung below and arm on lower ladder rung
Inventor: HYMER ERWIN
IPC: E06C1/12
Filed: 1975-02-24
Abstract: The drop hook is of the type used on a sliding ladder, the length of which is adjustable by moving lengthways at least one upper ladder component led along the component below, using a cable-pull locking and release is effected by drop-hook fastened to one of the components, with its activating elements engaging rungs, or other elements, on the other component. The drop-hook (25) on a swivelling mounting on the inside of a stringer of the upper component (1), is in the form of a two-armed lever. One of its arms (13) has its support surface fitting on the rung below (8), on the upper component, when in the catch position, to prevent the hook from twisting the selected rung (5) of the lower component (6) with a load-transfer effect across the lever's axis (24).

Title: Signalling visual information to blind person - involves using two channels or one channel which is modulated in two dimensions
Inventor: WITTE WOLFGANG DIPL PHYS DR
IPC: G09B21/00
Filed: 1975-03-19
Abstract: Methods are known for signalling the distance of an object. The apparatus seeks to give further information about the object by adding another type of signal (eg a mechanical vibration alongside a sound) or by modulating a signal in two dimensions (eg in frequency and amplitude). It is thought important that the additional information be specifically visual, eg colour, visual brightness, reflectivity to light, rather than represent the response of the object to some non-visual interrogation, eg reflectivity to ultrasonic waves. Ways are suggested in which a known automatic focussing device for a photographic camera - which in its present form measures distance only - might be elaborated to measure the visual reflectivity or brightness of the object, or, with the help of colour filters, give a coloure analysis of it.

Title: Transmission ratio control of independently driven members - by feeding pulse difference to transmitter generating differential signal
Inventor: SCHLOESSER HELMUT
IPC: H02P5/50
Filed: 1975-03-20
Abstract: Transmission ratio of two independently driven rotary machine members is controlled in that the differential speeds of the members are established in the form of pulse sequences and the digital pulses are subtracted from one another and the difference is fed to a transmitter, which produces a speed controlling value which is supplied to a setting member controlling the speed of the drive for one of the members. Pulse processing is pref. carried out electronically. The device is used for controlling speed and maintaining a constant transmission ratio between a rotary drum and an axially movable support in a textile machine. Electronic control permits of faultless and accurate endless setting of transmission ratio.

Title: Monitoring of alarm signal transmission cables for damage - uses capacitor coupled to sheathing that changes valve in event of damage
Inventor: RODE SEN JOHANNES
IPC: G08B29/06
Filed: 1975-06-06
Abstract: Detection of unwanted interference or damage to the transmission lines coupling an alarm detector to a receiver is provided by sensing a change in capacitance. Typically a sensor (A1) is coupled over two transmission cables (a1, b1) to a remote receiver (B1). The cables are located within a protective outer layer (S1). A capacitor (C1) is coupled between the shield and earth. Any damage to the shield produces a change in the capacitor rating and is used to trigger an alarm.

Title: Dust precipitator with coil - has rotating permanent magnetic drums with scrappers collecting charged dust particles
Inventor: NESTLER JOHANNES
IPC: B03C1/30
Filed: 1975-09-06
Abstract: The dust-laden gas is carried in a duct fitted with an insert (2) with coil (1) forming a strong magnetic field. The magnetic particles are electrostatically charged and are attracted to rotating permanent magnet drums (3). Scraper assemblies (4) fitted to the drums wipe off the collected particles which then drop into the collector chute (5). The gas pre-treated in this manner passes on to the electrostatic filter, the performance of which is boosted by the electrostatic precipitator. Hence, the space requirement for the filter is reduced by 50%. The rotating permanent magnet collecting drums are made of an alloy which retains its magnetic properties and is resistant to corrosive gases up to 600 deg. C.
