Patent DE-2828224-A1 (DE)
Title: Variable-frequency oscillator with two phase shifted outputs - has narrow band phase shifter, fixed-frequency auxiliary oscillator and two mixers coupled to local oscillator
Inventor: BAUR KARL PROF DR
IPC: H03D7/16
Filed: 1978-06-28
Abstract: The variable-frequency oscillator has a local oscillator (Ov) connected at its output to two signal paths (S1, S2). Each path contains a mixer (M1, M2) and a filter (F1, F2). An auxiliary oscillator (Ok) is connected directly to the mixer in the first path and indirectly via a 90 deg. phase shifter to the mixer in the second path. The filters are connected to output terminals and allow either only the sum or the difference frequencies produced in the mixers to pass through to these terminals. The local oscillator has a variable frequency and the auxiliary oscillator a fixed frequency. The advantage lies in avoiding the use of broadband phase shifters.

Title: Fuel injection nozzle for IC engine - has conical thermally conducting outer jacket to reduce temp. variations at nozzle
Inventor: WILLENBOCKEL OTTO DR ING
IPC: F02M61/16
Filed: 1978-07-28
Abstract: The nozzle opens into the suction manifold of the engine. It has a body (14) with an accurately machined nozzle (16) at the end of the body. An outer jacket (22) fits round the body and extends beyond the nozzle. Its outside has a circular cross section and its inside has a conical profile beyond the nozzle to suit the shape of the jet issuing from the nozzle. The outer jacket is of a material having a high thermal conductivity. This reduces temp. variations at the nozzle and prolongs its life by preventing corrosion resulting from condensation.

The pivot shaft of the top disc is mounted with a bearing (74) in a bracket with three arms (78). The ends of these arms are kept centralised between two spring-loaded pins. The position of the pins can be adjusted by means of nuts (90, 92). When the cutters are used to cut plastic foil, the top cutter is tilted by adjusting the stops.
Patent DE-2837626-A1 (DE)
Title: TDM exchange with PAM signals - which are at first integrated into stepped curves with samples from them taken and converted into digital signals
Inventor: KESSLER ARTHUR ING GRAD
IPC: H04Q11/04
Filed: 1978-08-29
Abstract: In the time multiplex system, PAM signals are used, and in a certain connection converted at first into bipolar PAM signals, and then into PCM signals. PAM signals coming in to a connection leading to a PCM system are integrated in a corresponding demodulator into a steped curve. Demodulators allocated to the outputs of individual connection paths are connected to a modulator collecting bipolar amplitude samples, through a high-pass filter passing the stepped signals. The outputs of the modulators are connected together to the input of an A-D convertor which converts them to digital signals.

Title: Heat-sinking system for loudspeaker - increases power output by using woven-copper centring membrane bonded to aluminium coil former
Inventor: GAUS HARRY DR
IPC: H04R9/02
Filed: 1978-10-03
Abstract: The heat sinking system has the moving-coil loudspeaker's centring membrane made of thermally conducting material and connected via thermally-conducting connections to the moving coil and/or to the support frame of the loudspeaker. The membrane may consist of a weave of copper thread. The membrane is bonded to a thermally conducting coil former. The coil former may be made of aluminium. All the thermally conducting parts of the heat-sinking system are good thermal conductors. Increasing the heat conducted away from the loudspeaker allows the loudspeaker's power rating to be increased. The system described here may be used in conjunction with other cooling systems to achieve greater power increases.

Title: Tube mill for grinding material - has double plate material transfer with transfer orifice in baffle plate adjustable during operation
Inventor: SCHEUCHER FRANZ ING
IPC: B02C17/06
Filed: 1978-11-08
Abstract: The tube mill is divided by the material transfer device into chambers and the two ends of the shell are seated in bearings.

Title: Shredded sugar beet drying - in first mechanical press stage and second thermal drying stage with heat recovery
Inventor: VALENTIN PETER ING GRAD
IPC: C13B15/00
Filed: 1979-01-05
Abstract: Shredded sugar beet is first partly dewatered mechanically by a press and finally after an intermediate storage passed by a conveyor to a thermal drying plant. The vapours produced by the thermal drying process are passed through a heat exchanger and are utilised to pre-dry the shredded sugar beet either in the intermediate bunker or on the conveyor. This saves the energy contained in the hot drying vapours and eliminate the pollution of the environment by them.

Title: Two=part collapsible roadside sign post - has vertical action spring and hinge linking folding part to base
Inventor: WEBER HOLGER G
IPC: E01F9/627
Filed: 1979-03-23

IPC: B65H29/60
Filed: 1979-10-18
Abstract: The form guide device for single forms, which are supplied by a form separating device with reader and are forwarded to a subsequent post processing device comprises a device for paper transfer which accepts the separated forms, and a receiving device (8) for collecting and forwarding the forms, by which they are forwarded to the post processing device. The intent is to provide a compact device with low noise and operating fully automatically, with the aid of which forms (6) printed out by an electronic data processing system can be processed more rapidly in any format position and in different size and in which particular forms can be separated out. For this purpose, the paper transfer device is provided with a deflection device (11), controlled by the reader, for rejecting forms not to be supplied to the post processing device (3) and is constructed as a unit separate from the receiving device (8). Depending on the format position of the forms in each case to be processed, this unit can be fixed on one transverse side or pivoted by 90 DEG  on one of the longitudinal sides of the receiving device (8). <IMAGE>

Filed: 1980-03-26
Abstract: A general purpose thermometer with a triple scale has three different, mutually-independent scales each giving a clear reading. The scales consist of three parts at angles of 120 degrees to each other. A type of enamel effect is achieved on an uncoated capillary in that when the scale is viewed from the centre line of one scale side it appears on the face of the opposing scale. The inner faces of the scale are shaped to enhance the enamelled effect. The scale may consist of a different uneven number of parts, say 5. The angles between parts of the scale may be varied to alter the enamelled effect, e.g. angles of 100 degrees may be used. The scale is assembled by pressing, the scale into a holder.
