Title: Gas sample removal probe at high temperatures - uses water to suck sampled gas through probe
Inventor: WOLTER MANFRED ING GRAD
IPC: G01N1/24
Filed: 1974-12-19
Abstract: A probe for continuously removing gas samples from a hot environment, such as in the combustion chamber of a boiler is presented, such as in the combustion chamber of samples with steam making subsequent analysis of the gas simpler. Basically the probe consists of a number of cylindrical tubes, one inside the other, with the front end terminating in a nozzle element fitted into the innermost tube in a slightly excentric manner.

Title: Liquid flow measurement transducer - depends on ultrasonic waves transmitted with and against the flow and uses piezo-electric devices
Inventor: BAUMOEL JOSEPH
IPC: G01F23/296
Filed: 1974-12-24
Abstract: The transducer consists of two piezo electric crystals (37, 38) mounted at a specified angle and clamped to the pipe (31) so that an ultrasonic signal can be sent from either one and be detected by the other after one reflection off the far side of the pipe. The whole arrangement is simply clamped to the outside of the pipe, which may be of plaster or cement, with suitable clamps (32, 33). A monitoring unit (34) performs the necessary data processing to produce a digital display of the flow rate in the pipe, which is derived essentially from an observation of the difference between the ultrasonic signals transit times in the two directions. The formula underlying the data processing is given, and involves the various mounting angles of the transducer. The monitoring network comprises an input unit (50) a measurement calculator (51), generating and counting networks (52, 53) a flow counter (54) and a display module (55).

Title: Tamper-proof identity card - has information recorded using photographic emulsion congruently through card thickness
Inventor: SCHEPPACH WERNER
IPC: B42D25/41
Filed: 1975-03-14
Abstract: The tamper-proof identify card has the information applied directly, with photographic emulsion, to the card blank. The information carrier is prepared on both sides such that after exposure the information is permanently detectable on the front side and back side of the card, and congruent, as can be tested in transmitted light. Preferably the carrier is made photosensitive over its whole thickness by impregnation with emulsion in the regions to bear information, so that the information is applied throughout the thickness. Two separate emulsion layers may also be used, with congruent information applied by through-illumination.
Patent DE-2514566-A1 (DE)
Title: Prevention of over modulation in monopulse doppler radar receiver - is performed by comparing signal with range defined signal
Inventor: PACOZZI PIERINO
IPC: G01S7/34
Filed: 1975-04-03
Abstract: Target tracking receivers in a Monopulse Doppler radar suffer from the effects of overmodulation due to climatic, clutter or interference effects resulting in undesirable echos. These are eliminated from the receiver. A Monopulse Doppler radar receiver has a sum and difference channels. The intermediate frequency amplifier in the sum channel has a constant output which is automatically controlled and depends on the basic amplitude of the signal from a given distance. The demodulated signal is adjusted and compared with a reference voltage. A coincidence gate is operated using the voltage comparator output signal and the output from a monostable used to lengthen pulses. The coincidence gate eliminates or attenuates the gating pulses for the blanking circuit as a function of distance.

Title: Seat belt fastener reminder - with warning signal in parallel to oil warning light
Inventor: HASSE HEINZ ADOLF
IPC: B60R22/48
Filed: 1975-06-18

Title: Rolled section handling system - has magnet grabs to grasp single sections with or without turning prior to removal to stacking area
IPC: B65G57/18
Filed: 1976-01-12
Abstract: The itemised handling of rolled sections is carried out by a midway conveyor and turned and placed in a temporary store for removal by lifting magnets and final adjacent stacking. The magnets grasp the setdown sections singly as required without turning and then carry them to the stacking area. The magnets travel in a closed circuit so that the sections are fed into this circuit and carried round by the magnets as they travel an upper and a lower track. The upper track runs in the conveying or feed sense and during this the sections are turned and grasped. They are set down in the stacking area while the magnets are travelling their lower track. The grabs are powered by chain and arranged below the feeder carrying the sections for handling.

Title: Folded closed carton convertible to open tray - consists of blank with folding lines facilitating conversion into larger volume tray
Inventor: FORSTER WILLIAM EDWARD
IPC: B65D5/20
Filed: 1976-11-27
Abstract: The carrier is for use with frozen food products, such as dough, having a substantially larger bulk volume at an elevated temperature than when frozen. The container is erected from a container blank having fold lines so arranged that, when the blank is folded along a first selection of fold lines it defines a container having a bulk capacity of a first predetermined volume. When folded along a second selection of fold lines, it defines an open, tray-like container having a bulk capacity of a second larger volume than the first volume, and a base area different from the base area of the first configuration. The ratio of the volumes is preferably 1:2. The blank may be glazed or lined on at least one side.

Title: Two pin socket outlet with recess for plug - has spring mounted guide plate to facilitate plug insertion
Inventor: SAUER ARTUR
IPC: H01R13/447
Filed: 1977-01-13
Abstract: A guide plate n18) is mounted in the recess which takes the plug. This plate can move axially in the direction of the contact sockets (13, 14), and, when the socket is not in use it occupies a position at the outer end of the recess. A spring (23) ensures that it returns to this position when the plug is withdrawn. In the unplugged state the guide plate indicates the position of the contact sockets so that the plug can be inserted correctly without difficulty. In the absence of such a plate the contact sockets (13, 14) may be invisible, especially if the fitting is mounted close to the floor.
