Abstract: 748,918. Obtaining fluid samples from mineral formations. SOC. DE PROSPECTION ELECTRIQUE PROCEDES SCHLUMBERGER. Oct. 14, 1953 [Oct. 25, 1952], No. 28359/53. Class 85 [Also in Group XXIX] A device for obtaining a sample of liquid or gas contained in an earth formation 2 which is traversed by a borehole 1 comprises a sample-taking tool 6 and a gun member 4 by means of which the tool can be projected a short distance into the wall of the borehole by the explosion of a powder charge 5. The tool 6 consists of a hollow, cylindrical body 9 closed by abase portion 8, the chamber 10 formed in the body being closed at the top by a valve 11 constituted by a member 12 slidably mounted on a fixed piston 13. At its forward end, the body 9 is fitted with a head member 20 having a conical top surface 25 provided with a central orifice 23 normally closed by a cover 24. The head member is made of a soft, malleable metal such as pure aluminium. In operation, the apparatus, which may comprise several superposed guns each with a sampling tool, is lowered to the desired level on the borehole and the tools 6 projected into the wall on impact. The soft face 25 is deformed to fit exactly into the formation thus providing a seal against entry of borehole fluid. Simultaneously the cover 24 is fractured by the fluid pressure in the formation, the fluid entering the chamber 21 in the head 20. The oressure in chamber 21 causes valve 11 to lift, the fluid passing into and filling chamber 10. whereupon the valve closes to retain the sample due to vacuum formed below piston 13 when it was lifted and to the pressure in chamber 10. The tool 6. which is attached to the gun member 4 by cables 7, can then be withdrawn from the borehole. A wire mesh filter may be disposed between chambers 21 and 10 when it is desired to exclude solid matter, for example, sand, from the sample. Specification 748,929 is referred to.

Title: Improvements in or relating to the manufacture of artificial silk
IPC: D01D5/14
Filed: 1929-09-19
Abstract: A stationary spinning funnel for use in the stretchspinning process has a flared bottom portion as in the parent Specification and also has longitudinal recesses, channels or grooves affording an even internal surface, formed within its walls so as to control the movements of the coagulating liquid and of the filaments.  The funnel may take the form of a fish-tail developing from a true cylinder at the upper end to an ellipse at the lower end, or as shown in Fig. 2, the funnel 1 may be abruptly flattened so as to form a channel down which the filaments are made to travel, thus reducing undesired disturbance of the liquid to a minimum.  In Fig. 3, the face of the funnel nearest the yarncollecting device is made concave.  As shown in Fig. 4, a groove 3 is formed in a vertical direction <PICT:0344560/IV/1> <PICT:0344560/IV/2> <PICT:0344560/IV/3> <PICT:0344560/IV/4> on the face of the funnel.  In use the filaments pass down this groove and cause a confined downward flow of liquid which cannot be greatly agitated by the upward flow.  For use in spinning separate bundles of filaments, the front face of the funnel may be indented as shown at 4 in the plan view in Fig. 7.  The filaments are thus divided into separate streams which may be separately collected.  The funnels may be used in connection with spinnerettes or caps adapted to produce two or more bundles of filaments in each funnel and the caps may have removable or adjustable nozzles fitted on to curved branches to direct the cellulose solution into the grooves in the funnel.

[Class 40 (iv)] [Also in Group XVIII] A coin-box arrangement is such that a coin, which may be inserted at any stage during the establishment of a connection, remains at the top of the shoot (in position I) so that it may be recovered directly if the call is ineffective. If the call is successful, a relay R1 responds to the reversal of current when the called party replies to short-circuit the speaking instruments and to withdraw the stop S 1. The coin thereupon falls to position II in which it closes contact K to short-circuit R1 and restore the speaking circuit. The coin is collected by the operation of a second relay R2 when an incoming or another outgoing call is made. The contact K may be only' momentarily engaged by the coin in passing in which case it is mechanically locked until released by R2. The arrangement may be adapted to deal with calls requiring more than one coin of the same or different values.

Abstract: 1,220,156. Controlling chemical processes; production of polyvinyl chloride. CHEMISCHE WERKE HULS A.G. 14 June, 1968 [16 June, 1967], No. 28428/68. Heading B1X. [Also in Division G4] A chemical process is automatically controlled by two identical digital computers which operate in parallel, which are each equipped with a large capacity backing storage facility as well as an internal store and one of which the working computer, receives information from the process and actively controls the process whereas the other computer, serving as a stand by computer, is merely supplied with data by the working computer but may take over control of the process when the working computer fails without interruption of the process. The chemical process is subdivided into consecutive working phases, each phase being capable of being repeated after any step in the working phase has been reached, and the working programme for the computers is divided into corresponding programme segments which are consecutively called into the internal store from the backing store as the process proceeds. The stand-by computer calls in the same segments as the working computer so that in the event of the working computer failing the stand-by computer can take over control by starting at the beginning of the current segment. Selected information relating to the process is stored in the backing store for eventual print-out. The invention is described as applied to the batch-wise production of polyvinyl chloride, the process involving the metering of liquid starting materials A to E into a mixing chamber 21, the transferring of the mixed materials into a selected one of a plurality of chambers 22 to 27 and the controlling of the temperature and pressure during the exothermic poly- ,merisation process. Polymerisation chamber 27 has jacket 38 fed with heating medium through pipe 40 and cooling medium through pipe 42. At start-up, the jacket is fed with heating medium until the desired pressure and temperature measured at 45, 46 are reached. The computer then controls operation of valves 41, 43 to provide the desired temperature in the jacket 38:
