Title: Valve fitting for press. measuring point - valve ball is loaded by spring compressed by split spring steel sleeve
IPC: F16L29/00
Filed: 1973-08-01
Abstract: The fitting body (1) has a thread (2) for fitting into the hydraulic system, spanner flats (4) and a thread (3) for the cap (12).

Title: Horizontal vacuum boiler for mfr of sugar - with suspended calender and design calculated to reduce pressure drop to a minimum and facilitate rapid crystallisation
IPC: C13B25/00
Filed: 1973-08-30
Abstract: The boiler comprises a tubular enclosure having a reduced vertical vol. with a low height for the mass above the upper tubular plate. In making white sugar, low press. steam should be employed and the boiler kept under a high vacuum. The circulation in the boiler which promotes crystallisation is created by the heating of the massecuite; this reduces its density, and more esp. its viscosity, in the neighbourhood of the heating tubes or other surfaces of the calender and causes it to rise to the surface under the thrust of the massecuite from the fresher regions of the boiler. The ascending movement is accentuated by the steam bubbles which form in the hottest portion of the mass; these rise and entrain the neighbouring particles.

Small retaining tabs are formed in the discs, pointing radially upwards into the slots. When the wire is wound on to the reel and the diameter of the winding reaches that of the shoulder, a turn of wire passes into the slots. The winding is then stopped, and the wire cut. The free end of the wire is held in place by the flexible tabs.

Title: Fluorescent tubes power supply - has thyristor controlling oscillation through series LC circuit with no transistors
IPC: H05B41/392
Filed: 1974-01-11
Abstract: An A.C. supply is derived from a D.C. source and is used for fluorescent tubes, particularly those employed in railway carriages. The circuit is transistorless obviating the problems associated with a varying D.C. input and tube condition and the consequent damage to circuits including transistors. The oscillator section of the power supply consists basically of a series LC circuit controlled by a Thyristor (2), all three elements are in series across the D.C. supply (+, -). Gating of the thyristor and the consequent output to the tube via a transformer (3) is derived from a pulse generator (1) providing one pulse per cycle, the duration of the sinusoidal waveform is dependant on the D.C. power level as compared with a reference source.

Title: Submicronic dust sepn from powder - esp. from alumina powder, using a fluidised bed with extra air jets
IPC: B03B4/00
Filed: 1974-01-30
Abstract: Purifying powder particles from impurities consisting of a fine dust having dimensions notably smaller than and adhering to the particles, comprises passing the powder through a tank contg. a fluidised bed, the ascending current of gas removing the fine dust.

The pref. devices consist of various types of fluidised beds which may also be vibrated and the pref. application is the removal of fine dust from a powder used in the industrial mfr. of Al. Used e.g. for sepn. of submicronic dust consisting of carbon, oxides of Fe, Ni, cpds. of Na, contaminating alumina powder used for mfg. Al, the alumina having a size between a few microns and several tens of microns.
Patent FR-2217151-A1 (FR)
Title: Continuous chipboard prodn using steel bands - the mat being heated by heated bands before pressing
IPC: B30B5/06
Filed: 1974-02-08
Abstract: A continuous mat of chips is fed between a pair of endless steel bands and then pressed. The leading rollers of the bands are fitted with heaters so as to heat the bands and thence the mat before pressing. At first contact with the bands the mat is compressed so that no great pressure is required in the press to produce the required consolidation. The system thus eliminates moving the bands across a heated surface in the press.

Title: Solar heating system for building - mixes stored and return water to keep emission temp. low for max. comfort
IPC: F24D11/00
Filed: 1974-02-13
Abstract: The system utilises solar energy without concentration, and keeps the temperature constant between 25 and 40 deg.C. Thus emission temperature is kept low, for maximum comfort. This temperature can be maintained by a mixing valve for the stored water and water returning from the system. Ambient temperature can be maintained by varying the flow rate or speed of the water circulating through the walls. Additional energy can be provided by liquid held in a reservoir kept at constant temperature, and heated by any suitable means.

Title: Apparatus determining boron concentration in water - has measuring cell detecting radiation from neutron source
IPC: G01N23/09
Filed: 1974-05-21
Abstract: The appts. consists of a radioactive neutron source measuring cell which is limited by at least two surfaces contg. plane surfaces parallel to one another, a neutron moderator, a neutron reflector and thermal radiation sensors for detecting neutrons. These are all arranged in such a way that there is a linear relation between the time needed to collect the pulse count supplied by the neutron detector and the concentration of neutron-absorbing substance dissolved in the liq. The appts. can have an electronic data-processing unit attached to it. The neutron detector is in series of a pre-set counter and in parallel with a time sequence counter to produce a third count giving the counting rate and hence the attenuation introduced by the boron in the water.

Title: Holding articles in packs comprising one layer of thermoplastic sheet - by vacuum forming the sheet to enclose the widest parts
IPC: B65D75/30
Filed: 1974-07-11
