Title: Nuclear fuel tester - using gamma or x-rays for automatic defect detection in spherical elements
IPC: G21C17/06
Filed: 1970-11-18
Abstract: A collimated narrow beam of radiation from fixed source is passed through the outer shell of the sphere being tested and is only tangential to the core of nuclear fuel proper, the sphere lying self-centred on a pair of rollers so that it rotates about two orthogonal axes. The beam passing through the sphere shell falls on either X-ray sensitive luminescent screens viewed by Schottky photo-diodes or directly by Schottky diodes sensitive to gamma or X-rays. The detector output is evaluated in a logic circuit that only triggers the alarm signal when two successive pulses associated with a single defect, due to the method of rotation, are received within a given maximum period. The thickness of material through which the beam passes is constant and the double pulse effect above leads to high discrimination.

Title: Transportable grateless straw incinerator - has conical combustion chamber with tangential fuel and air inlet at base
Inventor: STEEN GERHARD
IPC: F23G5/40
Filed: 1973-11-13
Abstract: The incinerator is designed for burning agricultural straw after harvest in such a manner that it does not cause pollution of air. The incinerator can be mounted on wheels and transported to the area where it is needed. The straw is first baled and then fed into the incinerator tangentially at the base. The combustion chamber tapers upwards and it has a closed floor and the combustion air is blown in at by a blower mounted on the trailer frame. The conical wall and also the floor are hollow and this space is used for ducting air for ensuring complete combustion. These hollow walls form also a cooling arrangement for the incinerator outside walls. The inner wall of the conical combustion chamber can also have helically upwards diverting guide rib for the compacted straw. The air supply from the hollow walls ensures that the material is completely burnt before exit into the air and the outlet gases are enclosed by an air stream. This incinerator can be coupled to a baling press which picks up the straw compacts it and feeds it into the travelling incinerator.

Title: Stabilisation circuit for line transformer supply voltage - has supply voltage terminal connected to the transformer winding tappings
Inventor: DAUTE OTTO
IPC: H04N3/185
Filed: 1974-01-15
Abstract: The supply voltage terminal is connected through several electronically controlled resistors and diodes connected with them in series. The above resistors are controled by a control signal derived from the supply voltage, so that it is applied to different tappings, depending on its value. Supply voltage is applied to the beginning of a series circuit consisting of several transistor collector-emitter paths. Its beginning, junction points and end are connected through diodes to the winding tappings. Several resistors connected in series are inserted between the supply voltage terminal and the control signal source. Their junction points are connected to the transistor bases. The control signals source is the output of a comparator to whose inputs the effective supply voltage at the line transformer, and a reference voltage are applied.

Title: Capacitor cover plate with overpressure protection - has sealing plate with tight cable bushings responding to pressure
Inventor: KUNERT WERNER
IPC: H01G2/14
Filed: 1974-02-11
Abstract: The overpressure protection in the capacitor cover plate is intended for cutting off the lead wires of the capacitor under conditions providing liquid or gaseous or overpressure inside the capacitor housing. The overpressure affects a sealing plate which has a tight sealing bushing of elastic material for cable passage. The embedding of the bushing is such that an outer overpressure increases the seal, thus preventing the penetration of a medium under overpressure. The cutting off of the lead wire is preferably carried out by a blade with sprung or moving mounting. The blade motion may be actuated by pressure under which the sealing plate moves.

Abstract: The spring has close-wound convolutions, i.e. is a tension spring, whose inner diameter, when the spring is free is less than the outer diameter of the end portions of the rods so that, when assembled, the spring firmly grips the rod end portions. The adjacent extremities of the rods may be spaced apart or may abut, and in the latter case at least one of the extremities amy be spherical. The rod end portions may each have a screw-thread fitting the spring. The coupling transmits light tensile or torsional loads in link work.

Title: Conveyor drier for goods from an offset printing press - where a heat exchanger can receive part of the flue gas containing air for reheating
Inventor: VITS HILMAR
IPC: F26B13/20
Filed: 1974-03-15
Abstract: Conveyor drier for continuous moving product has besides the burner a secondary burner. An adjustable flap near the second burner acts as distributor of air containing damaging material moved by an air blower to either the heat exchanger or the secondary burner as required by either component. The connection between secondary burner and heat exchanger has exists where flue gas escapes. The hot air pipes are short of the blowers so that the blowers send out mixed air. The advantage claimed is less energy used by re-using warm air after removal of gas.

Title: Flow meter for air or other gases - with fast response and linear relation between flow velocity and indication
Inventor: KUNZ WUNNIBALD
IPC: G01P1/00
Filed: 1974-03-15
Abstract: The flowmeter can be used for air in vehicle fuel injection systems or for mass flow measurement of gases in the process industries. A tube of arbitrary cross-section forms a measuring chamber in which a magnetic field is established normal to the flow. Electrode plates are arranged parallel to the magnetic field and to the direction of flow and the measuring chamber is irradiated with ultra-violet light to increase the electron or ion concentration in the flow. The signals generated at the electrode plates as a result of the magnetic field and the flow velocity are fed to a subtraction amplifier with very high input impedance which determines the flow velocity from the difference between these signals.

Title: Ski-brake with rotary frame - has brake-wings which rest in bearing-plate around fixed and mobile pivots
IPC: A63C7/10
Filed: 1974-03-19
Abstract: The ski-brake comprises a rotary frame, fixed to the ski-surface and fitted with swivelling brake-wings. The rotary frame with brake-wings form a part that rests in a bearing-plate around a fixed pivot at the back and two movable pivots at the front. This device avoids rupture of the spring due to excessive tension, and resulting failure of the brake as well as unduly abrupt braking. The spring is formed as an M shape rod with its outer ends cranked to hold the wings, and pivoted at the sides. The centre is held in a pivot away from the axis of the first two pivots, to form a torsion spring.
