Abstract: 1,256,666. Controlling fuel supply. BODENSEEWERK GERATETECHNIK G. m. b. H. March 19, 1970 [April 19, 1969], No. 13361/70. Heading G1N. In a device for controlling the fuel supply to a propeller turbo-jet aircraft engine by means of a throttle lever and a trimming lever, a signal representing the desired value (determined by engine operating parameters) of the turbine gas temperature or the position of the trimming lever (which influences the turbine gas temperature) is compared with a signal representing the corresponding actual value, an error signal being used either to indicate to the pilot that adjustment of the trimming lever is necessary or to operate the trimming lever automatically. As shown, the signal representing the desired value of turbine gas temperature is provided from a device 3 in dependence upon the turbine speed n and the air pressure or altitude p o , this signal being compared at 8 with the actual temperature signal. If a difference exists an output signal #T is applied to a summing device 10 whose output operates a flashing device 13 or 14, via a gate 11 or 12, depending on the sign of the error. Movement of the trimming lever 16 (manually or automatically) provides an output #α which is supplied to the summary amplifier 10. In this manner the time taken for the engine to respond is obviated. In a modification, above a certain speed of the turbine, the desired value of the turbine gas temperature is additionally influenced by movement of the throttle lever and the trimming lever, Fig. 4 (not shown). Alternatively, Fig. 5 (not shown), the position of the trimming lever is the regulating parameter in which case the signal representing the desired position of the trimming lever is additionally dependent upon the air temperature. Elements of the circuitry shown are known and described in connection with Figs. 6-16 (not shown).

A photographic material having a reduced tendency to formation of water-repellant spots comprises a support bearing a hydropholic polymer layer carrying an organic colloid layer wherein the colloid layer contains a polyfluorocarbon compound capable of reducing the surface tension of water to 15-20 dynes per sp. cm. and having the formula:- C b -C H -(A)-(Z) where C b  represents a perfluoroalkyl chain of at least 5 carbons and which may be interrupted by ether linkages; C H  represents a direct bond or an alkylene or oxyalkylene group containing at least 2 carbon atoms in the chain; A represents -CO- or -SO 2 -; Z represents a substituted amino group or the group OY, wherein Y is H, an alkali metal or an ammonium group. The perfluorocarbon compound may be a perfluorocarboxylic acid or derivative thereof of the formula C b -CO-Z or a perfluorosulphonic acid or derivative thereof of the formula:- C b -C H -SO 2 -Z. The colloid may be a waterpermeable organic colloid which may contain radiation-sensitive silver halide or a matted acrylic polymer. The support may be a polyethylene terephthalate film having an anchoring substratum of a vinylidene chloride addition copolymer of at least 35% by weight vinylidene chloride (U. S. A. Specification 2, 779, 684 corresponding to Specification 786,176). The object of the present invention is to prevent areas of the photographic material remaining uncoated after the coating operation due to the presence of oily contaminants.

Abstract: 1,259,323. Grinding. TOYODA KOKI K.K. [trading as TOYODA MACHINE WORKS Ltd.]. 16 Sept., 1969 [19 Sept., 1968; 9 July, 1969], No. 45492/69. Heading B3D. A grinding machine comprises a grinding wheel 3 carried by a support 2 mounted on a bed 1, a table 41 mounted on the bed to support a workpiece W, a cooler 47 for coolant supplied to continuously cool the workpiece throughout a grinding operation, means 4 for feeding the grinding wheel toward and away from the workpiece, wheel return means for actuating the feed means to separately return the grinding wheel for a selected period to permit cooling of the workpiece from a grinding position on the workpiece to a predetermined position after a rough grinding operation by the feed means, and means for generating a signal after the selected period to again advance the grinding wheel for fine feeding. The means 4 consists of a piston which is movable in a cylinder and rotatably mounted on the rod 6a of a lead screw 6 engaging a nut 7 on the support, backlash between the nut and screw being eliminated by a spring and further nut. A gear 10 on the rod 6a engages, through an idler 11, a gear 16 on a shaft 12 which is rotatable by a handwheel or by the rack of a slow speed actuator 20. A wheel positioning means 27 is engageable by the end of the lead screw 6 and is adjustable by a pinion 30 engaged by the rack 37 of an actuator 33. The workpiece W is mounted on the table 41 and is engaged by a sizing device 42, and coolant is supplied to the workpiece from a nozzle 44 connected by the cooler 47 to a solenoid operated valve and pump 45. When a start switch is operated, the wheel 3 is rotated and coolant supplied to the workpiece. Cylinders 4 and 20 are actuated to advance the wheel at a rapid rate until the stop 27 is engaged by the lead screw 6 whereupon the wheel is advanced to effect a rough grind. Thereafter the wheel is withdrawn from the workpiece for a predetermined time to permit the workpiece to cool before the grinding wheel is again advanced to effect a further rough grind until the sizing device operates to effect a fine grind and spark out for a predetermined time. In another embodiment, the wheel is dressed while retracted from the workpiece after the rough grind by a roller 54 rotated by an hydraulic motor 75. The roller is carried by a slide operable by a device 60 to advance and retract the dresser, a screw 55 being rotatable by a device 69 to advance the roller a dressing amount and a device 83 being operable to rotate the screw 6 and advance the wheel to compensate for the reduction in size of the wheel. In another mode of operation, the wheel is not retracted after the rough grind to permit cooling of the workpiece but is reduced in size by the dressing device 80 as to be out of contact with the workpiece, and then advanced for fine grinding and, after fine grinding, an amount to compensate for dressing. Also, the wheel may not be withdrawn for a predetermined time but until such time as a thermocouple of the sizing device indicates that the temperature of the workpiece has fallen to a satisfactory value.

An extraction vent leading to a ventilating duct has a valve member therein that is movable transversely of, or substantially transversely of, the vent opening to control the airflow without the valve member moving into or out of the opening. The rear edges of the valve and housing lie in a common plane-or substantially so-to reduce the noise level. In one form, Fig. 3, a valve body 1 is positioned within a seating 2 that leads to the duct and the body 1 is secured by a bolt 7 to a plate 6 blanking off one end of the seating. The body can be moved longitudinally of the seating by sliding the bolt 7 along a slot 8 in the plate 6. In another embodiment, Fig. 5, a wedge shaped valve body 1 is moved along a slot 8 in an inclined face 6 on the seating 2. This movement alters the width of a gap 4 between faces 10 and 11 at one side only of the body 1. The valve body may have a porous filling.

Abstract: 1,266,417. Modifying bitumen. P. THORSEN. 11 March, 1969, No. 12706/69. Heading C3N. A method of modifying bituminous materials suitable for use as road paving materials comprises thoroughly mixing said bituminous material with a rubber material which is in a low polymer liquid or semi-liquid state and which lacks modifying effect, in the absence of a solvent for the rubber material, and imparting to said rubber material a modifying effect by vulcanization in situ. By the term "low polymer liquid or semi-liquid state" is meant a material having a molecular weight less than that of natural rubber and is conveniently defined as meaning those materials having a Mooney viscosity not greater than 40 (ML-4, 100‹ C.). Thus the rubber materials are homogeneous substances as distinct from dispersions of rubber particles in a liquid, e.g. a latex. The rubber material may be synthetic or natural rubber although in the case of the latter this is used in a depolymerized form. The rubber material may be added to the bituminous material in a monomer state and thereafter converted to said low polymer liquid or semi-liquid state. In the example asphalt at 150-160‹ C. is modified by means of polychloroprene, in an amount of 1À5- 5% by weight, which is in an uncured and semiliquid state. After thorough mixing the rubber is vulcanized by means of a vulcanizing agent consisting of 9 parts of zinc oxide, 13 parts of petroleum oil, 3 parts di-O-tolylguanidine, 4 parts monoethanolamine and 2 parts of phenyl- α-naphthylamine based on 100 parts of rubber.
