Title: Machine tool sliding carriage reversing device - has switching rail which is actuated by a rotating tripping mechanism
IPC: B23Q16/00
Filed: 1973-12-28
Abstract: The machine tool carriage reversing mechanism actuator can be operated manually or it can be incorporated into an automatic control system. The carriage actuates stops at the end of its travel which are connected to a sliding rail. This rail slides in a direction parallel to the rail. The reversing switch is actuated by a sliding rail which is connected to a tripping dog. A pivoted trip lever is held on the pivot which is connected to the carriage. The pivoted trip lever has an opening which accommodates a pin which is also connected to the carriage. The pin determines the positions of the trip lever. This lever stops the sliding rail when the pin contacts the opening edge so that no rotation is possible and the rail actuates the reversing switch. This arrangement eliminates operating errors in manual operation.

Title: Total bilirubin determination - by coupling with diazotized sulphanilic acid in the presence of an accelerator
IPC: G01N33/72
Filed: 1974-01-11
Abstract: In the detn. of total bilirubin by coupling the bilirubin with diazotised sulphanilic acid in the presence of an accelerator there is used a mixt of accelerator (esp. caffeine) and sulphanilic acid activated by the addn of one drop of nitrite soln. Accelerator/sulphanilic acid mixts are stable and can thus be provided in pre-measured amts, so that the actual bilirubin detn involves only the addn of 1 drop of nitrite soln (variations in the size of the drop having negligible effect on the detn) adn the pipetting of the serum to be tested. This simplification to a single pipetting gives a saving in the time and a considerable increase in the accuracy of the detn.

Title: Fluid heaters and vaporisers - with fluid flowing through substrate surrounding heat source to increase efficiency and heating rate
IPC: F28F13/18
Filed: 1976-02-17
Abstract: The heat inertia of liq. bulks is minimised and the heating rate increased by feeding the liq. at a constant level, into a space contg. a source of heat and a substrate which has capillary, wetting and absorbent properties. The substrate absorbs the liq., reduces it progressively to infinitisimally small separate quantities, presents an expanded transfer surface in relation to the surface emitting heat and provides space for gaseous expansion, when the flu id arrives in the region of thermal radiation. The substrate is of vegetable, animal, or mineral fibres, and may have different diameters in successive layers, the smallest being at the heating zone. The method gives dry vapour, can be applied to water and other liquids, whether corrosive or not, permits recycling of waste water, provides a simple distn. process, reduces the need for insulation of generators of hot water or steam, and can be extended to all methods of heat prodn. usable in fluid heaters or vaporisers.
