Patent DE-2409880-A1 (DE)
Title: Chipboards from cakes of thermosetting resin-impregnated chips - by controlling heating so that thermosetting is reached at max. pressure
Inventor: PFEIFFER HEINRICH
IPC: B27N3/18
Filed: 1974-03-01
Abstract: Chipboards, made from cakes composed of thermosetting resin-impregnated chips, are finished in a press so that following mixing and impregnation of chips the cake heating to >100 degrees C is controlled continuously such that the cake reaches its thermosetting temp. at that pt. in the press at which the pressure has its max. value. Controlled preheating of the cake to the thermosetting temp. permits redn. of the max. pressing pressure and pressing time. In stage presses this pt. is attained between platens at the time when the pressed cake reaches its predetermined thickness. In continuously operating presses the pt. is attained at the nip of the press. Pref. the mixing and preheating of the chips and cake resp. is carried out in an enclosed space and the rate of throughput is controlled by measuring the temp. of the cake just before its inlet into the press nip.

Title: Captive rocket for rapidly forming airspace barrier zones - deployed over march routes, bridges, battle sectors, etc.
Inventor: ODENBERG FRIEDRICH W
IPC: F41H11/04
Filed: 1974-03-29
Abstract: Captive rocket for rapidly forming airspace barrier zones to ward off aircraft of all kinds comprises a rough-surfaces cable made of high tensile strength material having a high modulus of elasticity, which may contain a core of e.g. Cu wire for transmitting ignition and/or code signals.

Title: Recognition of spoken words or sounds - with subsequent printing of corresponding letters by machine
Inventor: SCHEFFLER GUENTER DIPL ING
IPC: G10L15/00
Filed: 1974-05-09
Abstract: Recognition of spoken sounds by computer is carried out by converting a sound to electrical signals which are passed through filters each having a different pass band. When a test sound is spoken, certain filters respond which are released by the frequencies in the sound and which act as a criterion for subsequent recognition of the sound. The filters which respond actuate switches which are connected in series in a store circuit including a relay which prints the corresponding letter(s). Pref. the test sounds used are the phonetic sounds appearing on p. 653 of Langenshceidt's "Taschenworterbuch English-Deutsch, Deutsch-English, Neubearbeitung 1970".

Title: Space monitoring device for an intruding object - is especially for declaring free a track section by a laser beam in railway signalling
Inventor: GERKE RUDOLF
IPC: B61L29/18
Filed: 1975-01-14
Abstract: The space is monitored by a focussed beam for presence of an object of a certain minimum size. The beam may several times pass through the monitored space along different paths. When it reaches a tuned receiver, the space is signalled as free. Before each monitoring process the intensity of similar external radiations is measured at least in the receiver area, whose direction coincides with that of incident beam. This value is used for the receiver sensitivity reduction at least for the next monitoring process. This reduction is stepped up with increasing radiation intensity.

Title: Stereophonic headset for realistic reproduction - have acoustically coupled canals driven by twin loudspeaker diaphragms
Inventor: LEPPER WILHELM DR ING
IPC: H04R1/10
Filed: 1975-02-03
Abstract: The headphone set consists of a lightweight U-shaped tube which has openings or recesses on the inner circumference with pads for the ears of the listener. The device is worn with the yoke in a horizontal position from the temples to the abck of the head. The two front ends of the acoustically dampened tube are fitted with left and right-hand channel loudspeakers. At the junction of the left- and right-hand chambers is a butterfly valve for adjustment for optimum acoustic performance. By causing the sound wave front to travel parallel to the listener's ears, a far more realistic reproduction is achieved. This is particularly so if the original sound is picked up using 'dummy head' microphone techniques.

Title: Sealing an opening in a metal workpiece - where a disc is inserted in a counterbore and expanded to seal the hole
Inventor: PRIETZEL WERNER
IPC: B23P11/00
Filed: 1975-03-08
Abstract: In a process for closing or sealing an opening in a metal workpiece of prescribed thickness by means of a metal adapter inserted in the opening, the adapter rests on a supporting surface in the opening with some side play forming a gap, and a punch provided with at least one wedge-shaped profile or projection on its end surface punches indentations in the adapter near to the gap and/or in the workpiece, so that a part of the adapter or the workpiece is deformed and closes the gap. The thickness of the adapter is pref. less than the height of the opening above the supporting surface, which may include an undercut. The use of an adapter or sealing disc is much less expensive than providing a screw thread on both the opening and a bolt or plug used as a seal; the adapter is also less expensive than welding.

Title: Cooling system for several grouped circuit components - has liquid evaporating in heat sink cavities and recondensing in external condenser
Inventor: IRANI JAMSHED
IPC: H02B1/56
Filed: 1975-09-26
Abstract: The cooling system for several grouped circuit components, has cavities (3) inside its heat sink element containing liquid (4) that evaporates as the heat sink warms up and recondenses in a condenser outside the immediate vicinity of the heat sink.
