Filed: 1939-01-14
Abstract: 523,793. Kinematograph apparatus. BOSCH GES., R. Jan. 14, 1939, No. 1293. Convention date, Feb. 26, 1938. [Class 97 (i)] The pivoted member of a film gate carries a pressure plate and resilient edge guides for the film, and is movable into closed position against spring action; closure of the gate may be effected by a spring on the camera door which engages the pivoted member as the door is closed. As shown, the fixed gate member consists of an angle bracket comprising a limb 7 formed with an exposure opening 10 and a claw slot, and a limb 12. A casing 13, enclosing members 15, 16 of the camera mechanism passing through the limb 12, is secured to this limb, and receives pivots 20 secured to the pivoted gate member 17. Springs 21 on the pivots 20 urge the member 17 into open position. The member 17 is formed with a front plate 18, lugs 19 carrying the pivots 20, and a side plate 26. The plate 18 has an aperture through which a pressure plate 22 is pressed by a spring 24, engaging lugs 25 and the back of the plate 22 ; stops 23 formed on the plate 22 limit its movement. A spring blade 27 is secured to the side plate 26 and is formed with end lugs 29 which engage one edge of the film 30 ; stops 31, 32, formed on the member 17, limit the flexure of the lugs 29. A spring blade 34 carried by the camera door presses on the side plate 26, when the door is closed, to counteract the effect of the springs 21. The springs may be of such strength that, as the gate is closed, the film is positioned laterally before the pressure plate 22 is operative.

Title: Improvements in or relating to the manufacture of lubricating compositions and additives to be included therein
Filed: 1944-01-24
Abstract: Lubricating oil additives are prepared by reacting phosphorus pentasulphide with higher saturated aliphatic carboxylic acids or substitution products thereof, wherein the substituents are aliphatic, aromatic or naphthenic radicles connected either directly to the hydrocarbon chain or through ether, sulphide, selenide or telluride linkages.  In examples, phosphorus pentasulphide is reacted with (a) stearic acid, (b) a a 1-dicarboxy-diheptadecyl sulphide and (c) a a 1-dicarboxy-diheptadecyl disulphide, and in the case of (a) bis-(thiostearyl) sulphide is isolated from the reaction product. The odour of the additives may be improved by treating them with an alkali such as sodium hydroxide.  a a 1-Dicarboxy-diheptadecyl sulphide is prepared by refluxing a -bromstearic acid with alcoholic caustic soda and sodium sulphide to form the sodium salt of the required acid and then decomposing this with hydrochloric acid.  a a 1 - Dicarboxy - diheptadecyl disulphide crystallises out when a -mercaptostearic acid, acetic acid, iodine and sodium acetate are mixed together.

Convention date, Jan. 25, 1934. [Class 97 (iii)] [See also Group XXXVIII] The thermal conductivity of the various strata surrounding a well are determined by introducing into the well liquid having a temperature different from those of the strata encountered, allowing heat exchange between the liquid and the walls of the well, and introducing means adapted to indicate at the top of the well differences between the temperature actually prevailing at different levels and the temperature substantially as would prevail if all strata had the same average heat conductivity. In the form shown, a casing 1 to be lowered into the borehole carries thermocouples each with one junction exposed to the liquid in the borehole and the other connected to a body having high heat capacity. The casing contains a central column 2 extending outside the casing into the part 3. A number of copper bars 4 having a high heat capacity and insulated from one another are provided around the column 2. From each bar 4 two wires of different material pass to the lower end of the part 3 and the wires are connected to form a number of thermo-couple junctions 6 in series.

Title: Automatic means for regulating the calorific value of coal gas
IPC: C10B57/18
Filed: 1929-01-15
Abstract: 328,007. Croft, C. M., Buxton, R. H., and Wandsworth, Wimbledon, & Epsom District Gas Co. Jan. 15, 1929. Governors.-The calorific value of coal gas, mixed or not with water gas, is automatically regulated by means under the control of a recording calorimeter or like gas-testing apparatus. The regulating means, which varies the pull or vacuum on the foul main by operating through relay devices a throttle valve interposed between the retort bench and the exhauster, by varying the speed of the exhauster or by providing a controlled byepass at the exhauster, comprises a primary relay modifying the governor setting, and a secondary relay operated by the resultant setting to provide power to adjust the throttle valve &c. According as the calorific value of a gas sample burnt in a calorimeter d varies from normal, the recording needle, which is connected by a spring link to the pivoted jet-pipe of a relay e of the kind described in Specification 224,655, [Class 69 (ii), Hydraulic presses &c.], displaces the jet-pipe so as to cause liquid to enter one of two pipes e<2>, e<3> and move a piston in a cylinder f. The piston rod is connected to a lever f<2> having its upper end linked to a slide o' which is guided by an end cover g<2> of the secondary relay casing g and carries a roller o interposed between the relay jet-pipe g' and a spring-urged lever n<2>. A spring-loaded diaphragm or governor m, which is exposed to the atmosphere on its upper side and to the pressure in the foul main on the other, presses a slidable rod m<3> against the jet-pipe, which assumes a resultant position determined by both governor and primary relay and affecting the flow of liquid through pipe c' or c' leading to the throttle valve operating cylin. der c. An electric motor i drives a rotary pump sucking liquid from a reservoir in the pedestal h and discharging it through pipes l<2>, l<3> to the primary and secondary relays respectively. An interrupter p located in the pipe line l<3> for allowing liquid pressure to be exerted only intermittently on the primary relay comprises a piston valve normally preventing communication between inlet and outlet ports in the valve casing, but caused to be lifted periodically to allow liquid to pass by means of a tappet resting on a cam disc driven at slow speed. Another piston valve may be provided to control the supply to the secondary relay.

In the form shown, the springs 17 are attached in triangular form to the motor housing by rivets or screws 18 and their ends are supported in insulating shoes 20 of rubber or synthetic resin having upstanding edges to prevent axial movement of the springs. After insertion of the unit in the outer casing 10, the shoes are fastened to the casing and to the springs in any suitable manner. The Specification as open to inspection under Sect. 91 (3) (a) states that the springs are so secured to the casing of the cleaner that their ends have slight peripheral play with relation thereto. This subject-matter does not appear in the Specification as accepted.
