Title: Building heating energy requirement reduction - using forced circulation of warm cellar air through wall cavities
IPC: F28D21/00
Filed: 1974-08-08
Abstract: The building is constructed with outside and inside walls which are 15cm. thick and have a cavity of 5cm. to 10cm. between them. Below the building is a cellar, with a duct leading into the cavity and provided with a fan to circulate the air.

Title: Cement calcining process and plant - fuel inlets in preheater permit use of fuel oil with high sulphur content
Inventor: NAUDY RENE
IPC: C04B7/43
Filed: 1974-09-11
Abstract: Process for converting raw materials in cement prodn. in which the solids forming the raw materials are heated to remove hydroxides and carbon in a vertical multi-stage heat exchanger consisting of several cyclones, and then passed to a calcining furnace in counter current to a stream of hot gas from the furnace. The flow of solids from the penultimate cyclone into the final cyclone depends on the degree of decarbonisation of the solids leaving the penultimate cyclone. A fuel and a hot combustion mixt. is pref. fed into the stream of gas leaving the furnace. The pref. device consists of a rotary drum calcining furnace and a battery of preheating cyclones. A fuel oil with a high sulphur content can be used to calcine and preheat the cement without forming deposits on the walls of the final preheating stage which normally occurs when the fuel oil contains more than 1% sulphur.

Title: Movement of slides in photographic projector - is performed by convex lever ensuring slide returned completely before advancing
IPC: G03B23/02
Filed: 1974-10-04
Abstract: Slides in a projector are moved by operation of a push-lever. Problems of synchronisation in projectors with rotating slide magazines are overcome by ensuring the complete return of each slide in its housing before advancing the magazine to the next slide. In a projector the slides are moved into the luminous beam by operation of a push lever (1) which has a rounded shape. The lever flops about a horizontal axis (2) and has an extension carrying a finger which operates in conjunction with a guide channel (6) in the base (7). The channel is shaped so that the lever progressively pushes its convex part on the slide to push it completely into its housing.

Title: Homing head for projectile with tracking sensor - has integral proximity sensor triggered by given angle or angular speed
Inventor: LIPS MANFRED
IPC: F41G7/22
Filed: 1975-08-05
Abstract: The homing head of the projectile is provided with an active or passive target searching and tracking sensor.

Title: Decorative illuminated articles - contg. a nontoxic, nonflammable liq.
IPC: G09F13/24
Filed: 1975-09-22
Abstract: Decorative articles comprise a body of fluid in a glass (or other transparent material) envelope and metal or plastic particles whose density approximates to that of the fluid. The fluid in these articles is heated from underneath by an electric bulb and the ensuing convection currents recirculate the particles to produce the effect. The fluid is trichlorotrifluoro-ethane which is non-toxic and non-flammable and is therefore acceptable in more countries than the liqs. hitherto used (e.g. trichloroethylene, perchloroethylene etc.).

Title: Selector isolator for HV testing of encapsulated switchgear - involves bulkhead insulation plate eliminating need for degassing large sections of ducting
IPC: G01R31/58
Filed: 1975-12-19
Abstract: The purpose of the selector isolator is to facilitate the HV testing of new installations thereby saving time and wear on equipment. Connections are brought out of the bus ducting (12) through a bulkhead insulation plate (13). A separate housing (1) containing the HV test bushing (2) and selector switch mechanism (3) is bolted onto the end flange of the bus duct. Thus only the end (14) of the duct and the switch chamber (15) have to be evacuated and filled with insulating gas for the test. Typically the selector is controlled by a hand wheel (11) driving through an insulation shaft (10). The contacts (7, 9) are all well rounded to minimise discharge at the high test voltages. Contact with the busbar ends may be by means of a spring loaded pin (9).

Title: System for discrimination of binary logic sequences - uses two adjacent detectors producing binary output indicating passage of object in determined direction
IPC: G01R23/00
Filed: 1976-07-07
Abstract: A logic discrimination system is able to recognise one or more particular information sequences in applications such as automatic object counting. The sequences are formed from two binary variables. An object passing through a gate passes from an upstream area to a downstream area past two detectors in a detection zone. The detectors sense objects in two perception areas chosen so that the object can embrace both detectors at one time. The detectors produce binary logic outputs for presence or absence of an object and the signals are processed after pulse shaping to determine direction of passage of objects from the binary sequence generated.

Title: Rectification of gas esp. in ethylene prodn. - using two columns in different temperature ranges minimises energy demand
IPC: F25J3/06
Filed: 1977-02-28
Abstract: A method of sepg. mixts. by rectification consists of first carrying out a partial condensation in one or more stages and the introducing at least some of the resultant fractions into a principal sepn. column. After the preliminary sepn. by partial condensn. the lightest fraction is introduced into a pre-sepn. column, in which no heat is supplied to the sump; the liq. fraction which condenses in this presepn. column, is removed unpurified and introduced into the main sepn. column. The lightest fraction introduced into the main sepn. column. may be either a wholly gaseous phase or a mixed liq. and gaseous phase. Used in partic. in ethylene prodn. plants. The gas obtd. from the pyrolysis furnace may be sepd. into any of the following (claimed) gps. of fractions: a C2- and a C3+ fraction; a C1- and a C2 fraction; or a C3- and a C4 fraction. The energy input required for the rectification process is considerably reduced by using two separate columns, which operate in different temp. ranges with relatively small differences between the head and sump. The presepn. stage in fact requires no input of energy at all.
