Abstract: 486,186. Centrifugal extractors. COMPAGNIE CONTINENTALE POUR L' EXPLOITATION DE BREVETS INDUSTRIELS. Oct. 15, 1937, No. 28121. Convention date, Oct. 23, 1936. [Class 23] The sieves or baskets of centrifugal extractors and similar apparatus are made of wire like elements 1 wound round supporting elements 2 mounted in suitable frames. At parts between the supporting members 2, the elements 1 are spaced apart by means of slight increases 5 in their thickness, or by means of two or three undulations in the elements, or by means of separate spacing pieces secured by welding. The means employed for spacing are narrow and cause little diminution of the draining spaces. The elements may be secured against radial displacement by bars 7 placed edgewise externally against the elements 1 and welded to some or all of them. The ends of the bars 7 are secured in the basket frame 6. In a modification, longitudinal members 8 have projecting portions 9 which act as distance pieces for the wire elements 1. The portion of the spaces between the elements 1 which follows the supporting members is protected by pieces 13 of wear-resisting metal such as phosphor-bronze or steel. Specification 164,500, [Class 23], is referred to.

Abstract: 1525989 Analyzing a liquid COMMISSARIAT A L'ENERGIE ATOMIQUE 8 July 1976 [9 July 1975] 28382/76 Heading G1A [Also in Division G2] In a device for analyzing a liquid 30 radiation from a light source 32 passes via a heat shield 40, a diaphragm 38 and a lens 36 into a flexible light guide 6, that is connected to one end of a rigid light guide 8, whose other end is intended to be positioned in a liquid to be tested. A further rigid light guide 10, a distance "d" away receives the radiation attenuated by the liquid and directs it to a further flexible light guide, which split up into a number of, separate channels 14, 16 and 18. The radiation from each channel may be analyzed for a different wavelength by employing an interference filter 58 adjusted to the wavelength concerned. The radiation from each channel may pass via a lens 62, an adjustable attenuator 56 and the interference filter 58 to be received by a detector 60 whose output is fed to a signal processing circuit 84. The intensity of the radiation emitted by the source may be monitored by means of another flexible light guide 42 and a detector 46 positioned as shown. The detector 46's output controls the power supply 4. A mechanical arrangement 26 conveys the test tube 28 containing the solution 30 to be tested in such a way that the solution 30 is brought into contact with the optical fibres. A programming device 76 controls the closing of relays by the supply 77 and also acts on relays 78, 80 and 82 to control sending of data to the processing device 84. The rigid light guides may be hollow and contain flexible light guide fibres Fig. 3 (not shown). In a further embodiment, Fig. 4, the rigid light guides 8, 10 project into a conduit 202 through which the liquid to be tested is circulated. In a alternative arrangement Fig. 2 (not shown) similar to the Fig. 1 system the liquid may be supplied to a test container from a series of reservoirs via relay activated valves. The rigid light guides are positioned in the container.

[Also in Group XXVI] A gas turbine engine air intake for use in a swept wing aircraft comprises vanes, adjacent the inboard and outboard edges at the forward end of the intake, which extend in vertical planes with respect to the wing, fully across the intake. A pair of engines whose centre lines are marked 12, 13 have a common intake 14. The front ends of the engines are indicated at 12a, 13a. The intake 14, which is divided into two by a wall 15, contains four vanes 16, 17, 18, 19 each of which extends across the full height of the intake. Vanes 17, 19 suppress break away of the boundary layer when the airflow is upward into the wing, i.e. ground running conditions. During flight, the vane 16 suppresses break away of the boundary layer. When the engines are throttled back, there is an outflow set up on the swept back wing. The curvature of flow causes break away which is suppressed by a vane 18. Vanes 16 and 19 can be used in any gas turbine engine intake. The vanes 17, 18 are only necessary in a multiengined installation. A boundary layer bleed control channel 20 may be provided.

The pyridinium salt reactants may be prepared by reacting anhydrous pyridine with an ester Br-CH2-C(CH3)=CHCOOR in, for example, benzene; this bromo ester reactant may be prepared by reacting appropriate senecioic acid esters with Br2 or N-bromo succinimide.  The nitrones may be hydrolysed in the presence of an acid yielding g -oxo senecioic acid ester, CH3C(CHO)=CHCOOR, which can be used as perfumes or foodstuff flavouring agents or as intermediates in the synthesis of vitamin A and carotin.

Title: A sterilizable package including a surgical drape
IPC: A61B19/08
Filed: 1959-08-21
Abstract: A drape sheet for use during surgical operations is made wholly or partly of pliable, water-resistant material and is stored, in a sterilised condition, in rolled form with an interleaved sheet of a material, such as paper, which prevents sticking at sterilizing temperatures.  The roll is preferably enclosed within a protective wrapper.  When an operation is to be performed, the patient's skin is cleaned and disinfected and then sprayed with an adhesive composition.  The sterilized sheet is then applied to the skin over the operative area and pressed into close contact to make it adhere. Subsequently the incision is made through the sheet which, remaining stuck to the skin, prevents the passage of infection to the wound. The sheet is transparent at least over the operative area and may be of heat-stabilized transparent polyvinyl chloride sheet.  If desired, the transparent sheet may be associated with paper sheets attached along its edges.  These provide additional p  protection but are not stuck to the patient.  Specifications 814,001 and 925,077 are referred to.
