Title: Automatic character recognition, in readers for blind persons - involves use of rotating disc holding character set
Inventor: HOSAGASI SEVKI DIPL ING
IPC: G06V10/88
Filed: 1973-09-22
Abstract: The process and arrangement for automatic character recognition are such as to make them particularly applicable to readers for the blind, wherein characters may be communicated mechanically or acoustically. Recognition of printed or typewritten characters is effected with the aid of a rotating disc which has characters and digits on its periphery in masks. When the printed line is scanned, character by character, a magnitude is formulated whose first term is derived by comparison with the masks, which are completely transparent, their surrounds being absolutely non-transparent. The second term on the magnitude is obtained by comparing relative density of printed areas on the page with its density at the beginning of the line, so obviating any influence of paper quality, lamp strength and photo-electric cell sensitivity.

Title: Grease extn. ventilator for cooking areas - with easily cleaned interior, reducing fire risk
Inventor: MOLITOR VICTOR DAVID
IPC: F24C15/20
Filed: 1974-06-20
Abstract: The ventilator comprises a series of generally concentric curved baffles, which direct air flow over the surface of a water bath contained in the lower part of the ventilator. Air flow causes the water level to rise up a curved plate at the rear of the water bath, so that grease, etc., is passed over the top surface to outlet. The unit is cleaned by adding detergent to the water bath and spraying internally with hot and cold water in an automatic sequence. Since the interior of the ventilator is easily cleaned, the risk of fire due to accumulated grease is greatly reduced.

Title: Plastics waste disintegrator with vertical axis rotor - has polygonal lower housing wall cooperating with rotor arms
Inventor: BECK ERICH
IPC: B29B17/04
Filed: 1974-07-04
Abstract: A disintegrator for plastics waste, esp. for sheets and blow-mouldings, comprises an upright, rotationally symmetrical vessel contg. a rotor with vertical axis and radial beater arms near the bottom of the vessel; the lower part of the vessel, adjacent to the rotor is constructed internally as a polygon, so that the flat faces of the polygon act as a substitute for inward projecting blades or other devices fixed to the inner vessel wall. Pref., this lower part of the vessel is constituted as a separate component in the form of a polygonal shell, pref. a removable component which can be replaced when worn. In particular, the flat faces may be of wear-resistant material. The use of a polygonal shape as a substitute for inwardly projecting blades or similar devices results in a considerable simplification and saving since the number of such blades may be up to 25. In addn. the construction of this lower, hightly abraded portion of the vessel as a removable component reduces the replacement or repair costs when it becomes excessively worn.
