Title: Photometric liquid sampling device - has emitting and receiving fibres linked to light source and photodetector
IPC: G01N21/85
Filed: 1974-05-22
Abstract: Photometric apparatus for several types of instruments e.g. a colorimeter, nephelometer, has a pair of optical fibres (1, 2) between a light source (3) and a photodetector (6). The emitting fibre (1) and face (7) is opposite the light source (3) while that (8) of the receiving fibre (2) is opposite the detector (6). The other end faces (7, 8) are placed inside a cavity (5) which receives a minimum quantity of liquid sample for investigation. Light from the source (3) is transmitted into the cavity from the end face (7) of the emitting fibre (1), crosses the sample, passes into the end face (8) of the receiving fibre (2) and thus reaches the photodetector (6).

Title: Rare earth metals sepn. and purificn. - by liq.-liq. extraction with di-(2-ethylhexyl)-phosphoric acid soln.
IPC: C01F17/17
Filed: 1974-06-14
Abstract: Title metals (at no. 57-71 and Y) are sepd. from mixts. of their salts by liq.-liq. extn. of an aq. H2SO4 soln. of the mixt. with a water-insol. of di-(2-ethylhexyl)-phosphoric acid in an organic diluent and opt. partial re-extn. of the metals in the organic phase with dil. H2SO4, a predetermined contact time being used in each case. The contact ime is calculated to give a high partition ratio for the elements extracted rapidly and a low partition ratio for those extracted slowly. The organic phase is freed from the (remaining) elements and re-used. An example of the extn. of Tb from Y shows that the sepn. factor can be increased to 17% above the equilibrium value by the use of a contact time of 6 min.

Abstract: The machine is for items such as bars or tubes, which are brought into contact with a grinder wheel rotating on an axis parallel to the axis of the item so that the peripheral speeds of the two are different at the point of contact. The shaft (11) carrying the grinder wheel rotates round the work in relation to a fixed support. This shaft can be caused to rotate on its (Y-Y) as it travels round the work axis (X-X) by the effect of a stationary annulus (14) meshing with a pinion on it, so as to form part of an epicyclic gear train. There can be an intermediate pinion (13) between the grinder wheel shaft pinion (9) and the annulus.

Title: Combined flow metering and sampling instrument - uses hollow cam together with rheostat and motor to achieve continuous sampling
IPC: G01F1/52
Filed: 1975-05-28
Abstract: The apparatus combines a flow measuring instrument and a sampling device within a single instrument and is used for pollution measurement. It is possible using solely mechanical means to obtain linear recordings of flow together with continuous sampling proportional to the instantaneous flows. Level variations are transformed using a specially designed hollow cam (2) into horizontal displacements proportional to flow. Flow variations are transformed directly by a rheostat (8) into variations of potential difference which in turn produce variations in the speed of rotation which in turn (9) which actuates the sampling system. The sampling is continuous and includes material in suspension without high speed pumping.

Title: Separator to remove particles from gases - has hollow tube section with conical deflector in the centre
IPC: B04C3/06
Filed: 1975-06-13
Abstract: Means of sepg. solid particles from a gas stream consists a hollow tubular section with a gas inlet, a gas outlet and an outlet for the particle rich stream. Along the section axis is a set of circular vanes to impart a vortex action to the gas and in the approach to the vanes is a deflector which guides the gas to the outer portion of the tubular section. This deflector has an upstream section and a downstream section which take the impact of the larger particles. The vanes form a circle around the deflector and extend to the edge of the tubular section. Used to separate solid particles from gas streams e.g. for use on i.c. engines, jet engines for aircraft or other turbines. The use of the deflector reduces the intensity of the vortex required for effective sepn. and therefore reduces the amt. of abrasion caused by the dirt particles.

Title: Heat exchanger tube with expanded press fit location - is stress relieved by stretching expanded tube section
IPC: B21D39/06
Filed: 1975-11-13
Abstract: Tubes of a heat exchanger are fixed to the end plates by hydraulically expanding the tube sections which are located inside the end tube plate holes. This expansion process indces tensile stresses in tubes which are attached to fixed end plates. To reduce this stress, part of the expanded tube section is stretched by an internal rolling process. Since the stresses which are produced when the heat exchanger is operating can be calculated, the stretching of the expanded section can be such that uniform minimal stress conditions are obtained.

Title: Reaming tool for deep drawn components - has twin blade cutting edges shaped to correspond to workpiece dimensions
IPC: B23D31/00
Filed: 1976-02-13
Abstract: The Reaming tool is for deep drawn components or workpieces, with two blades where the cutting edges have a shape corresponding to the workpieces to be reamed. The cutting edges perform a shearing action in a common plane. One blade is inside the workpiece and the other encloses the outside of the workpiece. The blades are moved relative to each other in this cutting plane in a continuous, practically enclosed circular motion. The blades remain completely parallel. The relative motion of the blades to each other is generated by a mechanism which converts a motion at right angels to the cutting plane into a practically closed rotary motion in this plane.

Title: Remote resetting vehicle direction indicator switch - has rocker arm released by steering mechanism actuated pneumatic or electric valve
IPC: B60Q1/40
Filed: 1976-02-26
Abstract: A vehicle direction indicator has a rocker switch (1) with arms (10, 11) underneath, each having a notch (8, 9) engaged by a tooth (6, 7) on a corresponding arm of a pair of arms (13, 14) with a spring between them to hold the switch down. This is released by a remote pneumatic switch operated by the return mechanism operated by the steering wheel. A rock moves by the steering wheel allows a spring loaded plunger to operate a diaphragm valve, which on return movement forces air through a tube (35) to force a piston (21) sideways and swing the toothed arm out of engagement with the rocker arm. A spring (3) returns the arm to its intermediate position. Similarly, a rocker arm can be remote returned by an electromagnetic switch.
