Title: Sterile area partitioned operating theatre - with partition permitting air passage from more sterile into less sterile area
Inventor: MEIERHANS ROBERT
IPC: E04H3/08
Filed: 1974-10-18
Abstract: The purpose is to combine max. atmospheric sterile conditions, allowing for germs of different grades, in an operating theatre with satisfactory air conditioning, achieving a very low germ level at an economically acceptable cost. There is a partition wall dividing the whole room into a sterile preferred area (11) and a lower-graded sterile area (12), arranged so that the wall permits the passage of air from the former into the latter. The top edge of the wall pref. joins the ceiling while the bottom is at an interval from the floor, leaving an open gap (10); the lower part may be in the form of a curtain (20), the whole wall having one part projecting from the rest, at right angles on both sides. There may be air outlet ducts in the lower-grade sterile area.

Title: Automatic height adjustment of flame cutting burners - where air jets keep capacitance measuring zone free from cooling water
Inventor: RASCHE SIGURD DR
IPC: B23K7/10
Filed: 1974-11-02
Abstract: Device for flame cutting workpieces uses a burner and a workpiece layout unit, e.g. a table, with capacitive stering of the burner height by a scanning electrode moving synchronously with the burner; either the burner is liq.-stabilised or a liq. table is employed. The novelty is that inside or directly adjacent ot the scanning electrode is a compressed gas nozzle, with its outlet directed towards the workpiece so the gas keeps the gap between this electrode and the workpiece free from liq. The nozzle is pref. located on the base of the scanning electrode. The device prevents the liq., e.g. cooling water, from interfering with the capacitance measurement.

Patent DE-2516671-A1 (DE)
Title: Logic for reliable automatic character recognition - can distinguish between printed characters with variable spacing
Inventor: RIESTER WOLFGANG
IPC: G06V30/10
Filed: 1975-04-16
Abstract: The printed characters pass under a narrow window and produce a waveform via a photoelectric cell and amplifier which is monitored by the logic circuit. The waveform is strobed by a clock to produce a bit at each increase in signal strength after the start of the character recognition interval, but no bit when a decrease or no change is detected. The pattern is then compared with a repertoire of patterns to determine the most likely printed letter. A detector to find the spaces between letters is also required so that the start of each recognition interval can be correctly timed. In the case of touching and even slightly overlapping characters a new recognition interval can be initiated once the first character has been successfully recognized.
