Patent GB-106630-A (GB)
IPC: F01L13/00
Abstract: 106,630. Fenchelle, H. E. March 24, 1916. Reversing; starting; stopping.-The engine is started in either direction by compressed air, some of the cylinders being fitted with valve mechanism to admit air to start it in one direction, while others have similar mechanism for starting in the reverse direction, liquid fuel being supplied simultaneously to those cylinders that are not being worked by compressed air. The invention is for cam mechanism A worked by a single handwheel B for controlling simultaneously the compressed air to the two groups of cylinders and the fuel, supplying the fuel in excess at starting and afterwards according to the speed desired. The cam is shown in the position for forward running at full speed. To stop the engine, the cam a<2> is brought beneath the lever F, which, through a spring e<2>, depresses the rod E and cuts off the fuel supply; the cams a, a<1> are also brought one on each side of levers d<1> for opening each of the compressed-air valves C respectively. The levers allow the cams to pass them, in stopping, without depressing the air valves. To start in a forward direction, the cams are turned in a clockwise direction; the cam a turns a lever d<1> and depresses the valve C, and simultaneously turns the lever D to engage the collar e on the rod E and supply an excess of fuel to some of the cylinders. By a further movement of the cams in the same direction, the air valve closes and the fuel supply is limited by the cam a<2>, and as the movement continues, the fuel supply increases until the camsurface a<2> no longer engages the lever F. The valve-gear is also adjusted for reversing by a pinion a<3> on the cam shaft and a rack H.

IPC: B64C13/00
Abstract: 106,639. McGregor, G. S. Oct. 21. 1916. Steering and balancing. --For steering and balancing an aeroplane in a vertical plane, the wings are adapted to be swung longitudinally against the elastic pressure of pneumatic cushions. Fig. 1 shows an aeroplane in plan having its rear spars pivoted at b to the frame. The front edges of the wings are connected by cords led over pulleys f to a cross-piece g carried by the plunger h of a cylinder containing oil or glycerine &c. The cylinder j communicates through a pipe q with a chamber k having an air space which constitutes the elastic cushion resisting backward movement of the wings under wind pressure. The pipe q is continued to n second chamber p, in which two plungers o, v, Fig. 2, are provided. The plunger o is moved by a screwed spindle s to effect adjustment of the system and for setting the machine in a desired altitude, and the plunger v is moved by a hand-lever x for ordinary control. A spring y normally balances the pressure of the plunger r on the hand-lever. A modification is described in which the front spars of the wings are pivoted, the rear spars being connected to plungers working in a single transverse cylinder. The control may act upon the cables instead of on an auxiliary plunger.

Title: Improvements in brushes and mechanical-painting or coating or cleaning devices
IPC: A46B11/06
Filed: 1931-04-13
Abstract: 376,747. Spray-producers. MAKINS, W. B. and BROWN & MAKINS, Ltd., 195, Uxbridge Road, Shepherds Bush, London. April 13, 1931, No. 10823. [Class 69 (iii).] A reservoir brush for cleaning or painting, operable with one hand while the other holds on to a ladder, comprises a brush head with a thumb valve allowing compressed air to operate another valve controlling the paint and air supply. In a modification the paint is not fed by compressed air. In the head 1, Fig. 1, is a passage 2 for compressed air which passes a thumb-pressed valve 5, Fig. 2, with a reduced part 5a. Pressure on a member 5 against an adjustable spring 24 allows the reduced part 5a to come opposite the outlet 6, Fig. 1, to lead air by a port 7 to a spring piston 9 and so to open a valve 10 to allow delivery of paint. A passage 11 supplies paint to a bore 12 and so to the valve 10. Compressed air is supplied to the brush by a port 26 and annulus 27a. To ensure a quick closing of the valve, a byepass 28 is made to release air from in front of the piston 9. In a modification, Fig. 3, a valve 30 is used and compressed air is not fed to the brush but simply operates the valve piston 9. Air pressure release is by a byepass 31. The supply line may be cleaned by removing the nozzle 27 and putting a plug thereon with a return bore from the part 26 to the bore 12. Air blows back through the open valve 10 along the supply to the container.

Abstract: 126,530. Fairweather, W., (Singer Manufacturing Co.). July 2, 1918. Eyelet-hole sewing-machines; starting and stopping gear; needles, vibrating laterally.-Relates to sewing-machines for forming a series of zigzag stitches succeeded by a line of straightaway tying stitches such as required in the stitching of eyelet holes common to Madeira embroidery. The machine is under manual control during the formation of the zigzag stitches and for changing the character of the stitch, and automatically acting means are provided for terminating the stitching operaticn after a predetermined number of tying stitches. A shaft 43 is manually operated against the action of a spring to set in action the needle-vibrating mechanism and through the arm 119 throw out the stop mechanism 62 which is held by a latch lever 103 with a trip arm 102. A cam 94 on the shaft 43 moves the arm 87 of a short rock-shaft 86 against the action of a spring 95. When the zigzag stitching is completed, the manual control of the shaft 43 is withdrawn and the shaft moves under the action of the spring 85 to stop the lateral vibrations of the needle, and allow the shaft 86 to rock and engage a lead-nut 90 on the arm 88 with a threaded sleeve 96 slidably keyed on the main shaft. The sewing operation is continued to form tying stitches till the movement of the sleeve causes a flange 108 thereon to trip the latch 103 and allow the stop gear to operate to stop the machine and raise the presser-foot. The needle-vibrating mechanism comprises a countershaft 18, driven from the main-shaft, through a two-to-one. reducing gear, and actuating through' an eccentric rod 20 a link 23 connected to the pivotally supported Needle-bar frame 30. This connexion consists of a stud 28 carried by the frame and journaled eccentrically in a cylindrical block 25 mounted in the end of the link. Adjustment of the block determines the field of vibration of the needle, the block being retained in any position frictionally by a spring-pressed plunger 41, and being provided with a scale traversed by an index finger 36 on the link. A movable pivot is provided for the link 23 by a stud 73 pivotally connected to an arrow 72 of a short shaft 71, and carried by one end of a link 74 provided with a hub 75 journaled in the end of the link 23. The shaft 71 is adjusted to determine the amplitude of needle vibration through the crank 70, link 69, and an arm 68 on the sleeve 48 resiliently connected with the control shaft 43. An index finger 81 travelling over a scale on the face-plate is also carried by the sleeve 48 and co-acts with stops 79, 80 corresponding respectively with the adjustments for. producing the tying and zigzag stitches.

Abstract: 1,205,692. Furnace roofs. GEO. P. REINTJES CO. Inc. 7 March, 1968, No. 11021/68. Heading F4B. The roof of a tiltable electric furnace comprises a self-supporting arch of bricks 42 carried by a peripheral ring element 12 of hollow triangular cross-section through which a coolant such as water or air is circulated. The ring 12 also carries a skeleton framework consisting of a centre ring 32 and radially extending spokes 28 to which are secured stringer bars 34. Certain bricks (e.g. in alternate rows) have mounted thereon a loop 54. Hanger members 56 formed with hook portions 58 and 60 each engage a stringer bar 34 and loop 54 as shown in Fig. 3. In use, when the central zone 33 of the roof collapses as is normal after prolonged usage, the outer zone of brickwork remains supported by the hangers 56 so facilitating repair of the collapsed central zone. The upper surface of loops 54 is spaced only slightly from the adjacent stringer bar 34, and this arrangement prevents undue shifting of the bricks when the roof is tilted with the furnace. Encased bricks are used and asbestos or other compressible packing 43 is placed between adjacent bricks.

Title: Photocatalytic oxidation of terpenes and derivatives thereof
IPC: C07C409/04
Filed: 1962-03-22
Abstract: Acyclic terpenes containing at least one C=C double bond preferably in position 2,3- and an aldehyde, hydroxyl, ketone, carboxyl or carboxylic ester group are subjected to oxidation preferably in a solvent medium, e.g. a C1-C6 alcohol with molecular oxygen, especially with air, by exposure to light, which does not contain any short wave ultra-violet component and in the presence of a photo-sensitizer which can transfer oxygen under the influence of light, and especially sensitizers which can absorb light which has been filtered through alkali glass, i.e. 350 to 590 mm , e.g. Bengal pink, Sudan-G, methylene blue, chlorophyll, Eosin, zinc-tetraphenyl porphyrine, dinaphthylene, thiophene, thionine or fused ring aromatic hydrocarbons, and if desired the oxidation products may be reduced. The reduction may be effected with sodium sulphite, triphenyl phosphine alkali metal aluminium hydrides or by hydrogenation using known catalysts to thus introduce into the molecule a hydroxyl group, or under such conditions to reduce the other oxygen containing group as well to yield glycols. The starting materials may contain more than one double bond.  Reaction schemes set forth the treatment of various starting materials including typically b -citronellol, b -citronellyl acetate, b -citronellal, Nerol, Geranial, Geranyl acetate, b -citral, b -linadod, b -linalyl acetate. In the examples citronellol, is oxidized in the presence of Bengal pink and then reduced with sodium sulphite to give a glycol, citronellyl acetate is oxidized in the presence of Bengal pink and then reduced with triphenyl phosphine, which gives the phosphine oxide, to give the acetoxy glycol which is converted to the glycol with alcoholic potash, citronellal is oxidized in the presence of Bengal pink then reduced to the hydroxy citronellal with sodium sulphite which on LiAlH4 reduction gives a glycol, citronellic acid is similarly converted to the hydroxy acid and with LiAlH4 this yields a glycol, and geraniol, nerol and linadool are oxidized and sulphite reduced to glycols.  Reference has been directed by the Comptroller to Specification 895,450.
