Title: High-pressure water distributor for downpipes
Inventor: ROLES CLEMENCE
IPC: E04D13/08
Filed: 1993-04-08
Abstract: The invention relates to a high-pressure water distributor (7) for downpipes (30). The distributor (7) comprises a pipe (10) which is produced from a flexible or rigid material and exhibits a water-tight bottom end (14) and an outlet connection (18).

Title: Reduction of the reject rate in the production of sand moulds
Inventor: GRABSCH GEORG
IPC: B22C9/02
Filed: 1993-10-07
Abstract: The invention provides a method for reducing the reject rate in the production of sand moulds. In this the separation of the pattern and the mould box formed is followed immediately by measurement of the weight of the pattern and comparison with predetermined standard weight. If there is a deviation from the standard weight, the pattern concerned is checked. Checking can lead to cleaning or replacement of the pattern and, as a result, as soon as a mould defect is detected no further defective moulds are produced. The (single) defective mould box formed can be marked as defective in the downstream part of the conveying line.
Patent DE-4337602-A1 (DE)
Title: Dynamic orientation aid and video simulator for the blind
Inventor: LEHMANN HANS-JOACHIM
IPC: A61F9/08
Filed: 1993-11-01
Abstract: The image pulses transmitted by a video camera carried along or by a video signal are transmitted by a computer to a stimulus converter and are detected simultaneously and in real time by the skin receptors via a perception surface which comprises individually controllable stimulation points and rests upon an area of skin having a relatively homogeneous surface. For this purpose, it is possible to use mechanical, hydraulic, electrical or thermal stimuli or stimulation by air nozzles or reduced pressure, individually and in combination. By combining different types of stimuli it is also possible to transmit different information via individual picture elements. By stabilising the direction of the lens and the picture detail, and by computer processing of the image pulses, the image perceived by the skin sensors can be adapted to the characteristics of the skin receptors. In this way it is possible for the blind person to orient himself/herself in a manner that is admittedly reduced but still realistic via his/her spatial environment or via the television picture.

Patent DE-4344404-A1 (DE)
Inventor: DAVIES ANDREW CERI
IPC: F24H9/20
Filed: 1993-12-24
Abstract: A control for an electrical heater 3 includes an inductor 4 with a primary coil 5 connected in series between the heater and an A.C. power supply 1. The inductor also has a secondary coil 6, which can be short circuited by a switch 8. When the switch 8 is closed the impedance of the inductor is only about 1 - 2% that of the heater so that current flow to the heater is substantially unimpeded. When the switch 8 is opened the impedance of the inductor 4 is greater than that of heater 3 so that current flow is reduced but some heating effect is still produced. With the switch 8 open, the inductor impedance may be about three times, or alternatively 50 to 100 times, that of heater 3. The switch 8 may be a manually-operated switch, a relay-operated switch, or a transistor. An additional switch 10 may be provided to prevent supply of any power to heater 3. The supply 1 may have a frequency of 400 Hz. A fan may blow air over heater 3 to produce a warm air flow. <IMAGE>
