Title: Cigarette packaging machine cigarette porosity testing device - has air jet and pressure monitor at end plate to operate ejector
Inventor: HEITMANN BOB
IPC: B65B19/32
Filed: 1976-05-14
Abstract: A cigarette packaging installation has a conveyor with containers (4) which are filled with sets of cigarettes of a determined number and which are conveyed past a pneumatic testing station, where if faulty cigarettes are detected, the contents can be ejected before they are inserted into captons. The air is injected and measured through holes through the same plate (14) at the end of the container. Air is injected through one set of holes (16) and monitoring devices (24 to 28) compare the pressure against a standard pressure. In the event of a low reading due to one more cigarettes being two porous, an ejector (29) is operated.

Title: Scanning gamma radiation detector - producing a three-dimensional image using crystals responding to separate collimator aperture arrays
Inventor: O'NEILL WILLIAM J
IPC: G01T1/166
Filed: 1976-05-19
Abstract: A gamma ray imaging system includes a scanning head with a plurality of crystals mounted on top of a collinator formed by a lead shield containing arrays of apertures. Each apertures has a focal axis directed down to a point at which all the axes intersect at relative acute angles. Each crystals responds to radiation from a different array of apertures and produces discrete and time-significant signals as the head passes over a radiation source. The system is used medically to scan radiation dispersed within or transmitted through a patient. The signals from the crystals can be automatically processed to derive three-dimensional stereoscopic images.

Title: Universal motor start and speed controller - uses two voltage dividers across stabilised DC voltage source
Inventor: FUNKE HUBERT
IPC: H02P1/24
Filed: 1976-06-25
Abstract: Arrangement for controlling the start and for stabilising the speed (revs) of a universal motor driven from an A.C source uses a thyristorised regulating unit controlled by a relaxation pulse oscillator by phase clipping control. To make the circuit arrangement insensitive to noise or interference, no matter from what source, two voltage dividers are used across the stabilised D.C voltage source, together with an RC network setting the pulse-frequency of the relaxation oscillator, and a capacitor connected to the second of the voltage dividers. The connection of the latter capacitor is taken, via an isolation or decoupling diode, to the divding point of the first voltage divider, and to the gate of a programmable unijunction transistor in the relaxation oscillator.

Title: Gasification of carbonaceous matter in fluidised bed reactor - under conditions of controlled temp. determined by reactive agents
Inventor: FRANKE FRIEDRICH H DR ING
IPC: C10J3/56
Filed: 1977-12-30
Abstract: Solid materials containing carbon are gasified by means of oxygen-contg. gases and/or water vapour or steam, CO2 or other gases, in a fluidised bed reactor having above the fluidised bed a post-reaction chamber. The distribution of temp. along the axis of the reaction chamber and/or transversely to it, is influenced by the feeding of the reactive agents. These are introduced into >=2 zones spaced some distance apart along the reactor axis, outside the zone of the fluidised bed, and also in the central and/or the topmost zone of the post-reaction chamber. The gasification is carried out under increased pressure, pref. at 30 bar. Oxygen contg. gases and/or steam are blown into the central and/or topmost zone of the post reaction chamber. The reactor can be operated much more flexibly both relatively to the characteristics of the carbonaceous material to the characteristics of the carbonaceous material to be gasified and to the constitution of the resulting gas mixt. The temp. along the reactor is controlled to give the desired results. The emission of sulphur into the atmos is also prevented at little expense.
