Patent DE-2744043-A1 (DE)
Title: Test jig for pulley belts - has hydraulically actuated slave piston to stretch belt and has flexible coupling hose
Inventor: BEER WOLFGANG
IPC: G01L5/08
Filed: 1977-09-30
Abstract: The system uses a hydaulic piston which is actuated by a threaded push rod with a rotating cap. The front edge of the cap passes over a micrometer scale on the piston housing to indicate the advancement of the piston. The piston housing is mounted on adjustable feet and has a dial gauge to indicate the pressure in the hydraulic pressure chamber. A flexible coupling hose transmits the hydraulic pressure to a slave cylinder on a testing jig. A pulley belt whose tensile strength is to be measured is clamped between the rear of the slave piston and two retaining shoulders.

Patent DE-2758964-A1 (DE)
Inventor: KALMBACH ULRICH
IPC: G02B6/25
Filed: 1977-12-30
Abstract: In the case of the connection, which has a connecting body which accommodates the optical fibres and in which two guide members (7, 8) coupling the optical fibre ends are arranged with abutting end faces, the ends of the optical fibres being terminated flush with the associated ends of the guide members, the aim is to achieve that the connecting elements are relatively insensitive to mechanical stresses and can be produced with high precision. For this purpose, the guide members (7, 8) consist of clock/watch stones on an aluminium oxide base, preferably of ruby material. The surface of the cladding can be curved in longitudinal section about a point situated on the longitudinal axis, the clock/watch stones then being connected to one another by a sleeve (10) into which they are pressed. <IMAGE>

Patent DE-2844583-A1 (DE)
Title: Courtesy light for motor vehicle - produces both white and IR light using only one incandescent lamp and sliding filter which can be locked in end positions
Inventor: THIEMANN HUBERT
IPC: B60Q3/02
Filed: 1978-10-13
Abstract: The inside light has a single incandescent lamp(14) producing both white light and light of longer wavelength (e.g. infrared). The incandescent lamp is located in a chamber(3) in the casing(1). The second chamber(4) contains an 'on' switch (7). A slidable filter (9) can slide between the two chambers -- i.e. being either over the component or over the lamp. The 'on' switch -- or at least its operating component -- is near the surface where the light leaves so that the filter cannot be left midway between its two end positions. The filter can be locked in both its end positions (i.e. over the switch and over the lamp). The advantage lies in avoiding the need for a second incandescent lamp.

Title: Hingeless limited tilt window wing retaining device - has side lug engaging groove round bottom edge, released beyond tilt setting
Inventor: WOLFARTH FRIEDRICH
IPC: E05C17/18
Filed: 1978-11-10
Abstract: The device is for safeguarding a window wing, with limited tilt, inserted without hinges in a fixed frame, esp. in a cellar, animal shed or similar, from being lifted out by wind or other forces. In the closed position the wing (11) is secured by a lateral protrusion (19) engaging a guideway (17) which runs freely in the direction of tilt about a bottom edge (14). The protrusion is at such an interval from the open end of the guideway that, when the wing is tilted, it is released from the guideway only on the far side of the tilt position limited by the extension mechanism (21). This provides reliable security.

IPC: H04N5/00
Filed: 1979-01-26
Abstract: 1. A method of transmitting a stereophonic signal on two separate sound carriers contained in a television signal, wherein a signal which is compatible for "mono" reception and which contains information both about the stereophonic left-hand and about the stereophonic right-hand information is transmitting over the one sound carrier and wherein a non-compatible signal, out of which, together with the compatible signal, the left-hand and right-hand information can be recovered separately from one another, is transmitted on the other sound carrier, characterized in that, at the transmitter end, a signal (R) representing the right-hand information and a signal (L) representing the left-hand information in a corresponding manner are added and the sum is then divided by two, that this last signal is transmitted, as the halved sum signal (R+L/2), on the one sound carrier and the signal (R) representing the right-hand information is transmitted in an identical manner on the other sound carrier, and that, at the receiver end, the halved sum signal (R+L/2), is multiplied by two and then the signal (R) representing the right-hand information is subtracted from this multiplied signal (R+L), as a result of which the signals of the left-hand information and right-hand information are restored separately.

Title: Alternating prodn. of coloured rubber mixts. - by introducing pigment with other additives into cooled tower mixer
Inventor: PENSHORN HEINZ-HEINRICH
IPC: B29B7/00
Filed: 1979-02-12
Abstract: During the changeover to a mixt. of another colour in a process for producing alternately coloured rubber mixts. of different colours, with a first stage in a kneader and a second stage in a cooled tower mixer with cylinders, the last charge in the kneader is mixed without pigment, and the pigment is only added in the tower mixer. The process eliminates cleaning time, prevents the faulty colouring or discolouration of a following batch and makes it unnecessary to put cleaning rubber through the kneader.

Title: Safety device for riveting machine - has switch actuated by pressure of riveting head on operator's hand
Inventor: STUZMANN HANNS
IPC: B21J15/28
Filed: 1979-02-22
Abstract: A riveting machine has the riveting head (22) mounted in a hollow shaft (18) and loaded by a spring (24). A rod (26) extending from the riveting head (22) normally keeps a limit switch (30) closed. This switch controls the electric circuit (40) which in turn controls the pneumatic valve (50) which regulates the flow of air to the actuating cyliner. If the riveting head (22) should touch the operator's hand the head (22) is pushed upwards against the spring (24) and opens the switch (30). The pneumatic valve (50) then stops the downward motion of the riveting head (22). The circuit remains closed if the head (22) touches a metallic object.

Title: Damp course for building walls - consisting of layer of silicified bricks
Inventor: DREES REINHOLD
IPC: C04B41/50
Filed: 1979-03-24
Abstract: A damp course for house and buildings to prevent rising moisture and water up the walls is produced by laying in the first course above the foundation plinth a layer of silicified bricks. A silicification of the outside surfaces and of the inside is obtained by placing the bricks in a soln. of an Si cpd., pref. water glass or silica gel. After extraction and dipping into a diluted soln. of hydrochloric or sulphuric acid, the bricks are dried and ready for laying. This is a simple way of creating a damp course and of creating a horizontal and vertical barrier for moisture.

Each path includes two parallel thyristors with the anode of each first thyristor connected to the cathode of each second thyristor and vice versa. The cathode of the first series thyristor (6) is connected to the anode of the other series thyristor (7) at the junction with the capacitor. The five connections join the system with the rectifier bridge, and the first two connections form the d.c. connections. Alternative circuits incorporate inductances forming chokes, and the three parallel paths may use triacs.

Title: Ultrasonic atomiser - with labyrinth droplet separator between mist chamber and face mask valve
Inventor: LAEMMCHEN KURT DR ING
IPC: B05B17/06
Filed: 1979-07-30
Abstract: An ultrasonic atomiser of liquids for use as an inhaler through a partial face mask consists of a plastic casing which houses at the bottom a high-frequency oscillator with transformer and rectifier and above it a threaded mist chamber with the fluid and a piezoceramic disc at the base. An annular plastic part with a coaxial insert, pushed over an opening, represents a droplet separator. The atomised mist must pass through these parts in a labyrinth path before it reaches the valve for the face mask. This prevents inhalation of water droplets which may block the lung passages, and passes only droplets of 2 mu.
