Title: Method and apapratus for determinging the integrity of the cooling system of a liquid cooled internal combustion engine
IPC: F01P11/14
Filed: 1974-01-31
Abstract: 1424165 Photo-electric detection of water in engine oil FORD MOTOR CO Ltd 31 Jan 1974 [28 Feb 1973] 04502/74 Heading G1A The presence of cooling water in the sump oil of an I.C. engine is detected by inserting into the engine dip-stick hole a probe carrying a light source and detector. As seen in Fig. 2 the source 28 and detector 30 are shielded from one another, the amount of light reaching the detector depending on the amount of the light from the source which is reflected off water in the oil. The detector signal can operate a meter or a no-no go lamp, Fig. 3. The source may have a filter 80 which passes only blue light; such light is absorbed by oil, and this ensures that only areas near the probe are  measured, thus avoiding reflections off adjacent parts of the engine. The probe may also be rotated to minimize such reflections. In Fig. 3 the current flow through detector 30 is amplified at 46 in dependence on the position of tap 58 on resistors 50-56. The amplified signal drives meter 48, and also a lamp 78 via a Darlington pair 76 whose on-off point can be adjusted at 66.

Filed: 1917-03-29
Abstract: 107,368. Hirschfeld, C. S., (Assignee of Ness, E. D. van). June 20, 1916, [Convention date]. Sprinklers, automatic.-In a dry-pipe apparatus for automatic sprinklers, the valve 3 is retained on its seat by means of closing mechanism, part of which is released by electrical means on the fusion of one of the sprinkler heads. The valve 3 is held against its seating by means of the screw 17 through a strut comprising a member 18 having outwardly-extending arms 19, 20, the ends of which are notched to receive the trunnion 31 of a turning member 23 having an extension 29 passing between the arms 19, 20. The member 23 is prevented from turning by means of a bellcrank lever 40 normally held by an electricallyinsulated link 32 consisting of two L-shaped members united by fusible solder, through which passes a wire connected to the terminals 47, 48. Air under pressure is forced into the distributing- pipes by means of an air pump 60, and a pressuregauge 52 is provided having its index finger 53 and a contact stud 55 connected to a battery 63 as shown, another contact stud 51 being connected to the binding post 48 and thus through the fusible link to the lower terminal of the battery. Air is forced into the dry pipe system until the gauge finger takes the mean position, as shown. On a fire occurring, the automatic sprinkler head fuses and air escapes, thus bringing the index finger 52 in contact with the stud 51. A current then passes through the wire 37, fusing the solder of the link 32 and thus releasing the bell-crank 40 and allowing the member 24 to turn on its trunnions and open the valve 23. Water then enters the pipe system and causes the finger of the pressure gauge to contact with the stud 55, thus ringing the alarm bell 66.

Title: Improvements in or relating to the production of esters and the esters thus produced
IPC: C07C69/24
Filed: 1960-02-10
Abstract: Esters of carboxylic acids and tertiary aliphatic alcohols are prepared by the alcoholysis of esters of an acid and a primary and/or secondary aliphatic alcohol with a tertiary alcohol having a higher boiling point than the primary or alcohol, under anhydrous conditions in the presence of an alkali-metal alcoholate catalyst, and the primary and/or secondary alcohols are removed by fractional distillation during the alcoholysis.  The catalyst, e.g. sodium methylate and potassium t butylate is added as a solid, or in solution in, for example, the tert-alcohol, and water may be removed from the reaction mixture before the addition of catalyst by boiling and distilling the vapour under a factionating column until the distillate is pure tert-alcohol.  Mixed esters may be obtained by choosing the ratios of the components and controlling the quantity of liberated primary and secondary alcohols removed.  Examples describe the preparation of t-butyl esters of caprylic, lauric and stearic acid from their methyl esters using potassium t-butylate and sodium methylate catalysts; of t-butyl and t-butyl-methyl diesters of terephthalic acid; and t amyl diester of sebacic acid.

Abstract: 539,821. Hydraulic brakes. HYDRAULIC BRAKE CO, March 18, 1940, Nos. 5030 and 5031. Convention dates, Oct. 10, 1939, and Dec. 1, 1939. [Class 103 (i)] In a liquid pressure braking system, comprising a pressure device for actuating a motor for applying braking elements, means (such as for example are described in Specification 539,850) for automatically adjusting the braking elements to take up wear, and means for retracting the braking elements and the motor there are provided means imposing a positive pressure on the liquid in the system of less magnitude than the pressure produced by the retracting means. A cylinder 36 for delivering pressure fluid to the motor through a conduit 22 contains a rubber floating piston 92 between the main piston and the cylinder outlet, a spring 108 being inserted between the two pistons. Pressure fluid passes around the floating piston when the brake is applied and upon release of the applied force the brake-retracting means applies pressure to the liquid in the conduit 22 and forces the floating piston 92 back against the pressure of spring 108 to uncover an annular passage 86 so as to allow liquid to pass into the cylinder and into the reservoir 28 through a compensating port 44 until the pressure of spring 108 returns the floating piston to a position in which it closes the passage 108 and thus produces a positive pressure. In a modification the sleeve 80 shown in Fig. 2 as partly containing the floating piston 92 has spaced by pass ports formed in its wall in substitution for passage 86 in the cylinders. Reference is made to Specification 486,935. Subject-matter contained in the Specification as open to inspection under Sect. 91 is described in Specifications 539,850 and 539,851.

Abstract: 369,722. Discharge apparatus GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and BREADNER, R. L., of General Electric Co., Wembley, Middlesex. Feb. 17, 1931, No. 5043. [Class 39 (i).] A method of sealing off a glass tube of wide bore consists in placing a closing - mem ber of fusible material preferably glass, within the tube, and then softening the member by heat so that is makes a fused joint with the wall of the tube. Fig. 1 illustrates the use of the method for sealing the exhaust tube 1 of a vacuum tube. The closing- member 3 consists of a bulb made from glass having approximately the same coefficient of expansion as glass tube 1 but having a much lower softening temperature. It is placed in a side tube 4 where it does not prevent the flow of gas to the exhaust pump, and it may be fitted with a coil 6 of iron wire to enable it to be moved along the tube by means of a magnet. A construction 5 is formed on the tube 1 at the place where the seal is to be made, and after exhaustion has been completed, the bulb is moved into contact with the constriction. The tube 1 is then heated at the constriction until the wall of the bulb softens and unites with the wall of the tube. The pressure of the air within the bulb assists in forming the joint.

Abstract: 311,810. Beatty, W. E., (Bell Telephone Laboratories, Inc.). Feb. 17, 1928. Copying - telegraphs. - In a copying-telegraph a beam of light passes through a moving picture film 14 to a lightsensitive cell 18 which controls electro-magnetic devices 31, 32, 33 to determine the punching of code combinations in a tape 48. The film is supported on a transparent drum 11 which is rotated and moved longitudinally relatively to the beam of light. The energization of the electromagnetic devices is periodically reduced or interrupted to restore them to the unactuated condition, by connecting in circuit with them a contact 23 which is closed by studs 23<1> on a drum 26 rotated with the drum 11. The electromagnetic devices consist of marginal relays which set up a combination in selector magnets 3, 5 which become effective by closure of their circuits at 22 by studs 22<1>. This is followed by the actuation of the punch magnet PM by the closure of the circuit of its relay winding 35 at contact 21 by studs 21'. A transmitter TT sends code combinations of impulses over a line L in accordance with the punching in the tape, and a mechanical perforator MP at the receiver perforates a tape 49 which operates a printer P' to print an image of the picture. Carriage-return and line-feed combinations are punched in the tape 48 through selector magnets 2, 4 which are operated by contacts 24, 25 through relays CR, LF, and impulses produced in accordance with these punchings control the carriage return and line-feed functions in the printer.

Abstract: 556,750. Regulating. BENDIX AVIATION CORPORATION. April 16, 1942, No. 5071. Convention date, April 10, 1941. [Class 7 (vi)] A throttle control is provided with means producing a torque acting thereon in opposition to the unbalanced force due to air flow past the throttle this torque being a maximum when the throttle is in an intermediate position, so that if the throttle, control should be broken, the throttle automatically takes up the intermediate position. The throttle spindle 19 is provided with an arm 20 connected to a telescopic spring device 52 anchored at 44. When the throttle is closed, the spring is in a .dead-centre position with regard to the throttle axis ; but as the throttle opens, the spring acts through the arm 20 with an opening tendency on the throttle. When the throttle is half open, the spring casing 40 elongates and reduces the force exerted by the spring. A closing-force may be exerted on the throttle when wide open, by a buffer spring 54, or by the action of the air flow on a projection at the underside of the throttle. In a modification, two springs are used, and one of these goes out of action as the throttle passes the half-open position. The closed or idling position of the throttle is controlled by contact of the arm 20 with a stop 30 eccentrically mounted on an adjustable rotary member 28, which also has a concentric stop portion 34 for co-operating with another arm 22 to provide a fixed limit for the wide-open position.
