Patent DE-2404716-A1 (DE)
Title: Magazine slide projector - with circular slide carrier to eliminate slide change mechanism
Inventor: SOHN JOERG
IPC: G03B23/10
Filed: 1974-02-01
Abstract: The individual slides are located onto a special slide carrier which has a circular shape. They are then transported through the projection position without the slides having to be removed from the carrier and replaced after each projection. The slide change operation is then simply controlled by turning the carrier. One design of carrier is in the shape of a frustrum of a multi-sided pyramid, with the slides fitted to the trapezium faces and with the carrier inclined on the projector. Another design has a simple, flat disc with the slides spaced around the circumference.

Patent DE-2418850-A1 (DE)
Title: Compressed transmission of binarily coded picture signals - involves converting picture signals converted into different length binary codewords
Inventor: ZAMPERONI PIERO DR ING
IPC: H04N1/419
Filed: 1974-04-19
Abstract: The picture signals are coded into runs which are decoded at the receiving end and reproduced. Binary picture signals are split by control signals into a sections of equal length and a constant codeword length suitable for each section is determined for the runs. This codeword length is coded for the receiving end run length decoder control and the coded codeword length is transmitted with the signal section codewords; at the receiving end the coded codeword length is applied to the run length decoder to assist in signal section decoding. Good ratios of signal compression are obtained with pictures rich in detail.

Title: Elastic membrane lining for water heater - reduces atmospheric corrosion of metal outer cylinder
Inventor: BAERH EBERHARD
IPC: F24D3/10
Filed: 1974-05-16
Abstract: In a heating installation fired by solid fuel, the metal outer cylinder of the heater is lined with a flexible, elastic material to keep the heated water and its vapour inside the lining and separate it from the region between the lining and the outer cylinder-which is open to the air. Without the lining, air in the upper part of the cylinder-which may, at times, be only part full of water - being air saturated with water vapour, would soon corrode the metal. With the lining, the metal encounters air of no more than ordinary humidity.

Title: Closed electrical machine with radial cooling slots - are connected to axial channels reading alternately to two end fans
Inventor: VOLL SIEGFRIED
IPC: H02K9/16
Filed: 1974-05-16
Abstract: The closed electrical machine has radial cooling slots in its stator and cooling tubes between the rear of the stator and the casing for the heat exchanger. Fan vanes are mounted at each end of the machine to drive air through the stator cooling system. The chambers in the region of the stator are open towards the rear of the stator. The rotor also has radial cooling slots connected with axial cooling channels in the rotor. These axial cooling channels are alternately connected to the one or the other fan. Avoiding any radial partitions in this manner, reduces the air flow resistance.

Several coaxially adjusted electrodes are mounted in the vacuum bulb, at least two of the electrodes being connected via an insulating part. This part is preferably an insulating ring. If the vacuum bulb is formed by a metal-ceramics structure the metal part carries an insulating ring supporting the other electrodes. Butt-welding or soldering may be used for securing the electrodes to the ring. Typically the insulating ring is inserted into the metal part carrying the cathode. Preferably the metal is non-magnetic, such as copper, and the insulating parts are formed from oxide ceramics, e.g. based on aluminium oxide.

Title: Frame for sliding window on vehicle - with elastic sealing lips and captive bearings along bottom and sides
Inventor: SENGEWITZ LOTHAR
IPC: B60J10/74
Filed: 1974-06-15
Abstract: The sliding window pane (1) is held at the bottom edge by a special plastic groove (3) on special bearings (4, 5, 6) which support the pane at the bottom and on either side. The bottom of the groove is provided with drainage ducts (19) to allow water and dust to escape while the top of the groove is fitted with soft, elastic sealing lips (14, 15).

Title: Heat treating textile goods capable of withstanding tension - modified hot flue ensures thorough penetration at uniform temp
IPC: F26B13/10
Filed: 1975-02-28
Abstract: Continuously running textile goods such as wovens, knitted, fleeces, etc. capable of withstanding longitudinal tension, are heat treated, esp. dried, fixed, steamed by passage through the processing atmosphere in an installation in which they are supported by widely spaced rollers, free to rotate in fixed bearings. The goods follow a meandering path in a series of almost closed loops, so that, in the unsupported zones, the processing medium flows through them. The installation consists of a closed vessel with a processing chamber in which two or more rows of rollers are spaced out in the line of motion at staggered pitch, and move the goods through. End on to the processing chamber, the blower chamber houses a series of fans for circulating the processing medium, by putting the insides of the closed loops under suction; perforated baffle plates restricting the flow through the loop openings. Combines the virtues of direct ventilation through the fabric, with those of the hot flue type installation. In a relatively small space, a long length of material can be processed at constant temp.
