Title: Multiple bandsaw assembly cutting block into planks - has double stage changeover gears with staging geared to total of pieces
Inventor: SCHULTE ELMAR DR ING
IPC: B27B27/10
Filed: 1977-05-05
Abstract: The saw assembly with bandsaws or similar separate saw units, divides a block into planks or other pieces of prescribed thickness. The saws are set in tandem, mutually offset by the thickness of a cut piece, each with a centre cutting device with rollers on cross ways adjustable chairs moves relative to a centre plane. The transmission drives for the centre cutting devices (I, II) on the first and last saws (1, 1') at least, are in the form of a double staged, centrally operated change-over gears, with a stage geared down to the chair adjustment in a ratio corresponding to the number of pieces. In the other stage the down-gearing ratios are inversely proportional. This enures that the overal tolerance is evenly apportioned among all the cut parts.

Title: Speed regulator for DC series wound motors - uses pulse averaging technique to provide control independent of voltage and load variations
Inventor: ALBRECHT HANS DIPL ING
IPC: H02P7/29
Filed: 1977-09-05
Abstract: A speed regulator is used for electric machines, particulary DC series wound motors. It uses a pulse generation and averaging technique to represent the motor speed independently of supply voltage or motor load variations. Two motor windings produce a waveform with frequency dependent on the rotational speed of the motor. This signal is rectified and applied through a buffer transistor to a monostable flip flop the output of which is a standard length to pulse train. This is smoothed in order to extract the average value and applied to a feedback control via an emitter follower stage.

Patent DE-2752827-A1 (DE)
Inventor: NIELSEN HANS BOERGE
IPC: D06B5/16
Filed: 1977-11-26
Abstract: The closing mechanism for cover plates of distributor pipes (1) in appliances for the wet treatment and drying of textile material contains a spindle (2), designed as an extension of the distributor pipe (1), and a sleeve (9) connected firmly to the cover plate (4). The inside diameter of the sleeve (9) corresponds to the outside diameter of the spindle (2). The sleeve (9) is mounted displaceably on the spindle (2). Annular recesses (6) are formed on the inside of the sleeve (9) and on the outside of the spindle (2). An annular spring (13) surrounds this spindle (2). Since the inner flanks (8) of the spindle recesses are made relatively flat, the annular spring can be displaced from the outside inwards from one recess to the other. A backward shift is greatly impeded by the steep outer flanks (7). The cover plate (4) can thus be detained in a specific position on the spindle. <IMAGE>

Title: Nose aerodynamic characteristics rhino-rheometer - has sensors to measure total volume breathed and trans-nasal pressure as function of time
Inventor: EICHLER JUERGEN PROF DR
IPC: A61B5/087
Filed: 1978-04-21
Abstract: The rhinorheometer measures and indicates the aerodynamic characteristics of both passages of the nose. During measurement, the patient breathes in through the nose and out through the mouth, and then in through the mouth and out through the nose. The total volume breathed is measured during breathing through the mouth, and the trans-nasal pressure as a function of the time during breathing through the nose. The aerodynamic characteristics are determined by electronic or other signal processing from the total volume breathed and the trans-nasal pressure as a function of the time.

Title: Manually operated spray pump with spring loaded pistons - has outlet valve at top of piston rod to minimise volume between valve and orifice
IPC: B05B11/00
Filed: 1978-05-17
Abstract: The pump is particularly intended for atomising a liquid. It has an axially arranged pair of pistons of different diameter in a common pump chamber. The smaller-diameter cylinder connects with an inlet. The two pistons are separate and only connected by a spring, their area of mutual contact forming the outlet valve. The inlet valve is contained in the smaller piston and the larger piston is connected with the spray head as in 2818724. To minimise the volume between the outlet valve (30, 31) and outlet orifice, this valve is arranged at the upper end of the piston rod (19) and not within the head.

Title: Fast synchronisation-signal converter - uses standard resistor network to convert synchronisation signal into digital angle signal
Inventor: SAUR HERMANN
IPC: H03M1/00
Filed: 1978-06-15
Abstract: The converter changes synchronisation into digital angle signals in equipment measuring a pole angle. The sync. signals are passed as voltages to an R-2R resistance network. The resulting approx. signal is applied to a series resistor. The voltage drop across this resistor is subtracted from the input voltage using an operational amplifier. The advantage lies in being able to use the converter for all those applications where separate directional components are not needed for preliminary processing.

Title: Heat recovery from waste fluids - with fluid level controlled louvres facing filter for improved circulation and efficiency
Inventor: IWAN KLAUS
IPC: F24D11/02
Filed: 1978-10-20
Abstract: Parent Patent described a plant, pref. based on a heat pump, which removes heat from waste water in a main basin, preceded by a clarification basin. Improvement is that the filter in the partition between the two basins is fitted on the main basic side with a hinged closure, consisting of float-operated louvres. This improves the heat exchanger effect because when the louvres are shut, the filter is closed and water can enter just through a bottom slot. The circulation cannot affect the settling in the clarification basin.
