Title: Radioactive contents capsule leakage measurement - with a spectrometer after immersion in helium
IPC: G01M3/20
Filed: 1971-05-12
Abstract: Rapid and sensitive measurement of leakage from sealed capsules by means of a mass spectrometer at measurement rates to the order of 30 secs. and sensitivities of 10-10 cm3 atms-1 plus-or-minus 10% with an error boundary of 5 x 10-11 cm3 s-1 plus-or-minus 20%. First stage leakage is established by direct spectrometer measurement following immersion of the capsule in helium and placing in a sealed container connected to the spectrometer. A second stage measurement follows connection of the vessel to a larger vessel of 10 times its volume evacuated to a low pressure. The two vessels are then both opened to the spectrometer and leak rates established. The nett capsule leakage is found by difference. Application to encapsulated Pu 238 thermonuclear generators for heart stimulators.

Title: Finished part degreasing - and sepn from shavings etc
IPC: C23G5/04
Filed: 1971-06-21
Abstract: Automatic degreasing and separation of finished metal parts from shavings, turnings, etc. is effected by feeding the parts and turnings into a separation column by means of a charging device, the flow of solvent pushing them into the column. The fine shavings clinging to the metal parts are thus separated and are subjected to a rotary current as well as a linear current so that, as they have a greater working surface than the finished parts re. their mass, they are swept via an overflow arrangement into a collecting vessel while the finished parts sink to the bottom of the separating column. The direction of solvent flow is then reversed and the finished parts are swept into a second collecting vessel.

Title: Gas heated water tube hot water boiler - is arranged for combustion gases to flow round both sides of water tubes
IPC: F24H1/40
Filed: 1973-06-08
Abstract: The boiler is rectangular with a base (2) and a front wall (23) containing a burner.

Title: Presampling device for liquids - removes samples required for quality control analysis from continuously flowing liquid
IPC: G01N1/20
Filed: 1973-11-07
Abstract: A sampler (1) is inserted in a transfer pipe (2) and comprises a housing which encloses a passage (4) which is crossed by a piston (5). This presents a hollow cavity across which the liquid flows continuously since it is constantly refilled by a representative sample. A receiving device (7) is placed below the sampler. In the chamber (3) the liquid flows around the piston and flows through the cavity (6) in the piston. To take a sample, piston (5) is moved so that the contents of the cavity (6) and the cavity itself leave the chamber and the contents flow into the receiving vessel (7). When the cavity (6) is empty the piston (5) is repositioned at its rest point when the cavity is instantly refilled and liquid flow across again.

Title: Fuel economiser and anti-pollution device - supplies additional air at low engine speeds when vehicle is stationary
IPC: F02M23/08
Filed: 1974-02-20
Abstract: A carburettor has a device (6) in the form of a T fitting which is installed between the carburettor (1) and the intake manifold (5). A non-return valve with a flap (10) of flexible material is held in the closed position by the tension spring (12) the load of which can be adjusted by the locknuts (14) and (15). At low engine speeds the butterfly plate (2) of the carburettor is closed, creating a depression in the inlet manifold and supplying a rich mixture which causes pollution through incomplete combustion. With the device operating the depression causes the valve to open so that extra air is supplied to ensure complete combustion and prevent pollution.

Title: Conical tube rolling mill - with four-roll stands in rough and two finish conicity sections
IPC: B21D51/10
Filed: 1974-08-19
Abstract: A rolling mill to produce continuously long conical metal tubes for use as lamp posts along motor roads consists of preparatory section where a rough conicity is given to a metal strip, and a finishing section with two elements where the final conical form is produced.

Title: Rope guide onto winch drum - has surface curve determined by resultant of rope forces acting on it
Inventor: CHEYLUS JEAN-FRANCOIS MARIE
IPC: B66D1/36
Filed: 1975-01-14
Abstract: The mechanism works in conjunction with the winch drum (2) and a fixed guide (4) in a plane (7) perpendicular to the drum axis and equidistant from the drum end flanges (3). An elongated rope support (8) extends parallel to the drum axis (6) and between it and the guide, for an equal distance on either side of the central plane (7). The support is curved near the respective drum flanges, the curve shape being determined by a tangent. This tangent is perpendicular to the resultant of forces represented by the direction of the rope effort exerted on the support in a plane perpendicular to the drum axis due to the change in direction as it passes over the support and by the force parallel to the drum axis due to the change in direction of the rope (1d) from the guide in the direction of this axis.

Title: Low voltage supply for fairy lights etc - uses ultrasonic transformer for reducing mains voltage
IPC: F21S6/00
Filed: 1975-03-21
Abstract: In order to utilise the longer life and general safety of low voltage electric light bulbs in e.g. decorative table lamps, without the use of heavy heat producing transformers, a low ultrasonic frequency device generating an electromagnetic field with the normal alternating current input and subsequent amplification of the developed low voltage to power the low voltage lamp is incorporated in the lamp base. A capacitor bridges the input voltage. The resultant field is transferred to the secondary winding which smoothes the voltage and a load resistance prevents surging of the lamp when switched on.
