Title: Method of handling flat bed lorry containers - uses transverse lorry rails for lateral lorry loading
IPC: B60P1/64
Filed: 1974-03-28
Abstract: Containers are fed between a lorry and a platform or elevator. The containers have rollers (5) to facilitate movement transverse to the lorry platform. Each container has an opening, communicating with enclosures which hold merchandise. There are transverse runways to allow the containers to slide and be guided. Telescopic legs are fitted to the ends of the runways and can compensate for level differences between the lorry and loading platforms. The containers can be of tubular construction.

Title: Sealing ring arrangement for servo-pistons - is restrained axially by collar on automatic transmissions for vehicles
IPC: F16D25/06
Filed: 1974-08-20
Abstract: The feature of this type of sealing ring design that applies mainly to servo-pistons used in automatic transmissions of motor vehicles is, that contrary to the usual practice where the sealing rings fit into pre-machined grooves, the sealing ring in this case are restrained axially by a small shoulder on the one side and a small collar or band on the other side which are designed to prevent axial movement of the ring. The piston can be pre-loaded by a compression spring in the normal rest position, so that the sealing ring is pre-loaded hydraulically prior to the movement of the piston taking place. Advantages claimed for this type of sealing ring fitting are low cost and ease of manufacture.
Patent FR-2241809-A1 (FR)
Title: Direct marking of photographic materials - by pressure transferring masking or desensitising material on photosensitive layer
IPC: G03C11/02
Filed: 1974-08-22
Abstract: A photographic material which can be marked for identification purposes comprises a support coated with a photosensitive layer which is itself overcoated with a material (I) which is radiation impermeable and can be transferred selectively, e.g. by application of pressure, onto the photosensitive layer to prevent exposure and development of the selected zones. For marking identification documents, passports credit cards etc. Prior to exposure, a mark e.g. a signature is applied on the impermeable layer and which is thus selectively transferred to the photosensitive layer; the latter is then exposed and developed to give a negative contg. the marks. The method is tamper-proof as the marks are made directly on the photosensitive layer and cannot be altered without leaving a trave.

Title: Radiant heater with exhaust flow through coaxial tubes - has inner burner and auxiliary openings through inner tube
Inventor: WARD TREVOR
IPC: F23C3/00
Filed: 1974-10-07
Abstract: The burner is fitted with air and fuel connections and with an ignition spark plug fitted with an extension so that the electrodes are within the combustion chamber. The combustion chamber is an innter tube with a number of holes allowing exhaust gases to pass directly into the outer tube, most of the gases passing into the outer tube through the open end of the chamber. The gases then flow back through the annular space which lies between the inner tube and the outer tube. The exhaust gases are expelled through an outlet port. An alternative to the radial holes is to drill the holes at an angle in the direction of flow of the gas.

Title: Automatic optical bottle flow line inspection device - delays fault detection signals to ejection device until bottles move from inspection console
IPC: G01N33/00
Filed: 1975-02-17
Abstract: A device for inspecting transparent or translucent objects such as bottles has an inspection console (10) located such that bottles on a continuous belt pass between two cabinets (11, 12) through a set of three photosensitive detectors (10a). One cabinet (12) houses light sources (13) which emit light through a window (12a) onto mirrors (35) which deflect the light onto the bottles. Electronic printed circuits (22) process detector signals to accepts or reject the bottles. Rejects are ejected from the belt by a piston. A control panel (24) on one cabinet (11) permits setting of the sweep limits of the inspection by the photodetectors to detect acceptable dimensions. FAult detection signals are delayed until the faulty bottles move from the console, and then applied to the rejection device.

Title: Dissolved substance concentration determination - by measuring current at anode effect onset during rapid cathode/anode voltage rise
IPC: G01N27/06
Filed: 1975-05-28
Abstract: The concentration of dissolved substances in condensed systems (aluminium oxide in fused cryolite baths of electrolytic aluminium cells) is determined by applying between a cathode and an anode a voltage rise which rapidly brings about an induced anode effect on the anode. The current at which this effect occurs is measured and the concentration of the dissolved substance is calculated from the current reading. This can be used to eliminate the undesirable anode effect which occurs when the Al2O3 concentration in electrolytic cells drops below 2%. The third (reference) electrode ensures a close control of the rate of voltage sweep on the control anode.

Title: Pollutants sepn from flue gases from drying wood - by washing with aq. alkaline soln. and pptg. pollutants
IPC: B01D53/72
Filed: 1975-07-04
Abstract: Flue gases from a wood drying process are first cooled by part of the wash liq. before passing into a washing chamber where they are washed by an aq. soln. contg. an alkaline hydroxide, pref. caustic soda. The wash liq. is then treated with either an acid, e.g. sulphuric acid, or an alkali, e.g. calcium hydroxide, so that any dissolved pollutants are pptd. out and can be removed by a centrifuge or filter press. The quantities of caustic soda and sulphuric acid dosed into the wash water are controlled by pH meters. Process is used for removing polluting agents, e.g. resins, oils, tan bodies, phenols, formaldehyde, from a wood drying process. The process removes the substances not taken out by water alone, e.g. phenol and some formaldehyde, thereby increasing the efficiency of washing process.

Title: Electroslag welding system - with accelerated welding rate by electrode preheating through extra current clamps
IPC: B23K9/173
Filed: 1976-05-05
Abstract: In an automatic or semi-automatic electroslag-welding process the electrode is preheated from a separate current source with currents of 40 to 900 A depending on the particular welding technique. A special preheating clamp is attached to the electrode between the welding current clamp and the electrode feed rollers; the preheating current source is connected both to the welding current clamp and to the preheating clamp. This increases the melting rate and therefore the productivity considerably, even for larger electrode diameters.

Title: Injection moulding rubber automobile tyres - using channels for suction of air from sidewall moulding cavities before injection of rubber mixt.
Inventor: GALLIZIA ACHILLE
IPC: B29D30/06
Filed: 1976-09-29
Abstract: Injection moulding of tyres is effected by placing the mould cavities, in which the sidewalls are to be moulded, under vacuum before the injection of the moulding mixt. by suction of the air at several points disposed symmetrically relative to the axis of the mould, close to the end zone of the sidewalls where these join with the crown.
