Title: Destoning machine for fruits - using reciprocating central cup on conical membrane moving in opposition to splitting cutter
Inventor: HAEMMERLE MARTIN
IPC: A47J23/00
Filed: 1974-03-07
Abstract: The stones of stone fruit are removed in the bakery industry in a machine in which the fruit is stored in a funnel shaped storage tank, with its central part formed by a membrane leading to a central reception cup for one single fruit. The cup is attached to a linkage by which it can be moved from a bottom position, where the membrane continues the cone shape of the funnel, to a top position where the membrane represents an inverted cone so that all fruit apart from the one in the cup falls back into the storage tank. A cutter blade, moving opposite to the direction of the cup, intersects in the lowest position the cup in its top position at the bottom aperture. The machine is simple and requires no manual intervention whatsoever. It has a fast working cycle and operates trouble free for long periods.

Title: Mass-produced meter measuring noise intensity at 60-1,000 Hz - uses pressure microphone and phase-corrected pressure-gradient microphone
Inventor: ISING HARTMUT DR ING
IPC: G01H3/12
Filed: 1974-07-19
Abstract: The pressure microphone is wholly conventional, while the pressure-gradient microphone has its special lightweight membrane accurately centred electrostatically. The outputs of the two microphones (1, with electrostatic adjustment 2, and 5) are amplified (3, 6) phase-corrected by known methods (4) and multiplied together (7); the product is filtered (8) and applied to a meter (9). The pressure microphone, as the more sensitive, has a diaphragm only half the diameter of that of the gradient microphone (1 cm as against 2 cm). The microphones are placed either side by side at 2 cm distance, or at right angles at 0.5 cm distance. Trials using a chamber where standing waves produced pressure differences without differences of intensity gave results consistent to within 1 dB.

Title: Facsimile transmission data compressor - has shortest code associated with most frequent points of same brightness
Inventor: ROTHGORDT ULF
IPC: H04N1/419
Filed: 1975-08-30
Abstract: The data compressor, for facsimile transmissions, reduces the total length of all code words in the transmission sequence of a document. A pseudo value is assigned to each number of sequential points having the same brightness. The most frequent number has a pseudo value associated with it that, when coded, gives the shortest code word for transmission. Less frequent numbers are assigned pseudo values whose code words for transmission are longer. Numbers smaller or greater than the most frequent number are assigned pseudo values proportional to the difference between this number and the most frequent number.

Title: Wedge angle optical measurement system - uses valve seating faces as mirrors with light projected onto screen
Inventor: SELBACH GERD DIPL ING
IPC: G01B11/26
Filed: 1975-10-28
Abstract: A measuring instrument is used to determine and display small angles especially in the production of tightly fitting valves for the petrochemical industry. The geometric differences between an emergent sharply beamed light signal and the incident beam are used to represent precisely the inclinations of the two faces to each other and to the central line of the body. The faces of the body are used as reflecting surfaces. The accuracy of measurement may be increased by increasing the distance between the reflecting faces and the plane to which the images are projected.

Title: Pressed plastics plant tray with tunnels between plant sites - has absorbent wick running through tunnels for watering plants
Inventor: NIELSEN LEO
IPC: A01G27/04
Filed: 1975-12-06
Abstract: The foamed plastics tray has several staggered rows of cups (1) to hold the earth in which the plants are to grow. Between each cup and the next is a drainage tunnel (2) whose bottom aligns with the bottom of the cups. Through the lines of drainage tunnels a horizontal length of absorbent wick (6) runs from cup to cup. At one end, the wick is raised to a higher level as it passes through the edge of the tray: outside the tray it hangs down. The plants are watered from the other end of the wick. The water the plant cups receives from the initially dry wick remains in them as long as required. When and only when, water is put on the higher-lying drainage end of the dry wick, it, too, becomes absorbent, and the cups are drained by siphonage.
