Patent DE-2440057-A1 (DE)
Title: X-ray tube operation method - involves supplying tube with voltage deviating from its nominal value, and tube anode current is varied accordingly
Inventor: ENNSLIN FRIEDER H
IPC: H05G1/34
Filed: 1974-08-21
Abstract: The voltage is applied to the tube through a loosely coupled h.v. transformer. A signal is delivered, indicating the value of a time integral of the tube cathode emission at the start of an exposure, and the exposure is ended when the signal reaches a preselected value; the anode current is varied by changes of cathode temperature; or in case of a Coolidge-type X-ray tube the anode current is varied by changing the cathode heating current; the relative cathode heating current variations are limited to 10 to 50% of the supply voltage changes.

Title: Two colour source colorimeter - illuminates specimen in sequence using two colours and synchronously detected reflections produce ratio
Inventor: FURUTA NAOFUMI
IPC: G01J3/50
Filed: 1975-02-20
Abstract: A colorimeter uses two light sources with distinctly separate wavelengths which are energised alternately by a time division exciter unit so that a light spot is directed by an optical system to a specimen under examination. The light reflected from the speciment falls on a photodetector which generates corresponding alternating output signals which are split in synchronism with the source excitation by a time division circuit. The resulting signals after amplification are compared in a comparator with a reference signal to determine the percentage of the reference signal level represented for each of the colours. The percentage reflections characteristic of a number of reference colours can be coded as an identification of the different colours for quick reference.

Title: Pastry prepn plant - with endless conveyors from dough dividing and stamping station to dough raising cabinet
Inventor: SCHIMKE FRIEDRICH
IPC: A21C13/02
Filed: 1975-08-13
Abstract: A pastry preparation plant consists of a conveyor which takes the rocking troughs from a dough dividing station into a dough raising cabinet. A cross conveyor stores the loaded troughs for the first raising period. After discharge by a pusher, another conveyor leads to a stamping station, a turning station and back to the cabinet for the main raising period. The troughs are then discharged to a baking oven. This system is simple enough to be suitable for medium-size bakeries. It does not upset the temp. in the dough raising cabinet at every charge and discharge. The pieces of dough form no dry skin and retain a uniform quality.

Title: Prestressed concrete vessel hot spots localisation - to detect defective insulation by temp. measurement of linear coolant
Inventor: SCHAUKI NABIL DR
IPC: G21C17/112
Filed: 1975-08-27
Abstract: Localising regions of high temp. in a prestressed concrete press. vessel, in which the various cavities ("pods" etc) are thermally insulated on the hot side of the liner and cooling tubes cool the concrete is described. The cooling tubes are temporarily blocked or throttled in various lengths or ranges of tube, by turns. When the throtting is released and normal flow is resumed, the temperature and flow speed are measured and recorded. From these recorded. From these recorded values, the hot spots in the vessel are determined. Pref. the duration of throttling and the selection of the coolant speed are determined to suit the position and geometry of the cooling tubes. Hot spots, indicating defective insulation, can be detected by relatively simple means.

Title: Microwave channel separator system - has sharp cut off frequencies and two port all pass filter modules with step shaped phase variations
Inventor: UNRAU UDO DIPL ING
IPC: H01P1/213
Filed: 1975-09-18
Abstract: A microwave channel separator has very sharp cut-off edges and is used to separate a frequency band periodically into a series of channels. It consists of 2x2 gating modules of hybrid design. The modules (C, D) are two port networks which form all pass filters with step phase shift characteristics. The steps are designed so that the phase difference of the two port networks increases by a given value. The transmission range between consecutive stages will determine the selection of the channels and is as narrow as possible. The all pass step shaped phase characteristic is produced by 3 dB directional couplers, with two arms connected to short-circuited or no-load cascaded lines which generally consist of several sections or different length and different characteristic impedance.

Title: Hand held powered grass shears - has comb like teeth moved with shearing action by motor driven eccentric gear
Inventor: JONES JOHN E
IPC: B26B15/00
Filed: 1975-11-28
Abstract: The attachment for the drive has a pair of planar cutting knives which have a specific number of cutting teeth for shearing material e.g. grass. The blades move back and forwards across each other repetitively. The adjacent and jointly operating cutting edges have their contact cutting point between the interacting edges of each pair of cutting edges. The blades move with a uniform velocity during each cutting stroke. The drive for the blades which both oscillate from side to side relative to the cutter housing, is by a gear driven eccentric which provides a long open period for the grass to enter the gap between and then a rapid cutting action. The motor may be powered from batteries in the handle.

Title: Installation measuring heat consumed - detects inlet and outlet temp. difference and liq. flow rate to produce pulse output
Inventor: KNAUSS UWE
IPC: G01K17/16
Filed: 1976-02-03
Abstract: Heat is supplied to a consumer through flow and return pipes, each of which has a resistance thermometer temperature probe. The probe outputs are applied to a differential amplifier to obtain a temperature difference signal. A flowmeter measures the fluid flow and provides a pulse for a predetermined volume. The temperature difference signal and flowmeter output are applied to a variable pulse width generator whose output is a pulse proportional to the inputs. These pulses pass to an AND gate with a high frequency synchronisation generator connected to its second input and with a counter connected to the output.

Title: Heating cartridge for hair waving - uses heat conducting wires to raise heat output at beginning of session but reducing later
Inventor: GOHDE KARL
IPC: A45D2/36
Filed: 1976-02-14
Abstract: Heating cartridge is for hair waving devices, hair dressing rods etc. The heating cartridge-through the use of heat conducting wires with a high temp. coefficient or temp. factor (ca. 2 at 400 C operating temp.)-raises the heating output by a factor of two against the operating output. As a result, the heat output lies at about 40 Watt and the operating output at about 20 Watt with the use of this type heat cartridge. The object is to obtain an increase in the output at the beginning of the treatment without the disadvantage of excess heat output during later phases of the treatment.

Title: Steam raiser from modified distillery evaporator - has burner and agitator added, raising distillation steam from mash preparation
IPC: B01D3/18
Filed: 1976-03-13
Abstract: Steam is produced for the duration of the daily distillation operation is a distillery, by supplying heat to the exchanger surfaces in a vaporiser contg. the starting materials. The vaporising vessel is tightly sealed and the steam generated is conveyed to a distn. column.
