Title: Improvements relating to central couplings for railway and like vehicles
IPC: B61G7/10
Filed: 1932-02-01
Abstract: 373,958. Combined buffer and drawgear for railway &c. vehicles. KRUPP AKT.-GES., F., Essen, Germany. Feb. 1, 1932, No. 3006. Convention date, May 1, 1931. [Class 103 (v).] In a central buffer coupling for railway &c. vehicles the stem G of the coupler-head is supported and centralized by means of a transverse spring H suspended at its ends from fixed brackets R by a 'pair of links K that are free to swing in all directions, means being provided for damping the swinging movement. In the arrangement shown the centre of the spring H, which is located to the rear of the headstock B, is rigidly connected to a squared portion g<3> of the stem G by means of a clamping plate P, bracket M, and U-shaped clamp L, while the apertured ends h<1> of the spring engage with washers k<2> backed by nuts k<1> at the lower ends of the links K. At their upper ends each of the links K are provided with lateral trunnions k<4> engaging vertical slots r<2>, r<3> in brackets R secured to the longitudinal beams A, A<1>. Longitudinal displacements of the stem G are accommodated by the links K pivoting about the trunnions k<4>, while lateral swinging movements cause the links K to tilt against the influence of the spring H about either the right- or left-hand pair of trunnions k4 with the edges of the slots r2, r<3> as fulcra. To permit these movements of the stem G, its rear end is universally jointed to the draw-bar F by means of a sliding casing D receiving the forward end of the draw-bar, the stem G having concentric spherical surfaces g<1>, g<2> respectively engaging spherical surfaces j<2>, d<3> on the draw-bar F and the interior of the casing D. In place of the joints described for the upper ends of the links K, ball-and-socket frictional joints may be substituted, or springs may be provided for damping the transverse swinging movements of the links.

Title: Oil burning apparatus
IPC: F23D11/10
Filed: 1924-02-06
Abstract: 232,721. Daechsel, F. A., and Powell, W. F. Feb. 6, 1924. Spray burners; oil supply; vaporizing-apparatus; flame deflectors. - In an oil burning apparatus, oil supplied through a pipe 27 is carried by an air blast through a nozzle or nozzles 20 extending through a water chamber 21 secured in the furnace or stove. The flames from the nozzles 20 play on flame-deflecting and heat-retaining members 24, 25, and thereby heat the water, which is continuously circulated through the chamber 21 to ensure vaporization of the fuel. When the oil burning apparatus is not in use and the water chamber 21 is required to serve as a grate for supporting asbestos, coal, or other fuel, the nozzles 20 may be closed by removable plugs 154. An electrically driven fan 10 enclosed in a lined chamber which is connected to the exterior of the building by a curved pipe 67 creates the air blast which flows through a pipe 16, branches 17, and pipes 18 to the burner nozzles 20. Oil is fed to the pipes 18 from the pipe 27 through a cut-off valve 35, sight-feed regulating valves 30, and reduced pipes 28. Shut-off valves 31 arranged at the connection of the pipes 18 with the branches 17 may be turned so as either to open the entrances to the pipes 18 and to close discharge openings 34 in the branches or to close the entrances to the pipes 18 and open the discharge openings 34. If the fan stops, a pivoted valve 46 in the upper side of the pipe 16 falls owing to the drop in the air pressure and withdraws a latch member 43, thereby releasing a lever 39 and allowing a weighted rod to close the valve 35 and cut off the oil supply. In alternative constructions the nozzles 20 extend through the bottom face to the top face of the water chamber 21 and pivotally mounted sections of the pipe 18 replace the valves 31.

Title: Improvements in transfer mechanism for glass blowing machines
IPC: C03B9/18
Filed: 1921-09-12
Abstract: 193,365. Imray, O. Y., (Obear-Nester Glass Co.). Sept. 12, 1921. Blowing. - A transfer mechanism is provided comprising pressure-operated mechanism for gripping a blank in a blank mould and pressureoperated mechanism for swinging the gripping device to lift the blank from the mould and deposit it in an inverted position in another mould. Figs. 1, 2 and 4 show the invention applied to a double rotary table machine of the type described in Specification 193,080. Simultaneously with the opening of one of the blank moulds on the rotary table 21, compressed air is admitted through a pipe 155, Fig. 2, to a port 142 and cylinder 134 driving a piston 146 outwards so that grippers 148 carried by the piston rod engage the neck of the bottle in the open mould. The cylinder 134 is mounted on a stud 133 rotatably mounted in a bearing 132 which can be raised and lowered by a piston 130, Figs. 1 and 4, working in a cylinder 129. A crank pin 136 is carried by the stud 133, and is adjustably coupled to a rod 139 pivoted at 141 to the cylinder 129. Immediately after the grippens 148 have engaged a bottle, compressed air from the port 142, passing through passages 143, 131<a>, Fig. 5, to the space below the piston 130, forces the latter upwards and operates the transfer device as indicated in dotted lines in Fig. 1 to deposit the bottle in an upright position in an open finishing mould. As the movement is completed, the port 145<1>, Fig. 2, comes into engagement with the port 142 and the gripper is retracted from the bottle. The transfer mechanism is returned to its original position by compressed air passing from the lower side of the piston 12 through a pipe 151, Fig. 1, and pipe 149, Fig. 5, to the space above the piston 130.

Title: Improvements in or relating to the arrangement of valves for controlling the admission of high and low pressure liquid to hydraulic presses
IPC: F15B13/02
Filed: 1921-01-27
Abstract: 176,983. Barton, B. C., and Carr, R. H. Jan. 27, 1921. Working valves.-The arrangement of valves described in Specification 151,839 is modified to prevent the possibility of the high-pressure inlet valve opening in the event of the low pressure failing from any cause; the automatic ram controlling the high-pressure valve being made of two diameters, the larger of which is acted on by the pressure in the press cylinder, while the smaller is acted on by the high pressure. The ram v works in chambers formed in blocks 4, x, disposed in an horizontal passage in a block a and carries a mitre valve w<1>, normally closing a passage t<4> leading from a chamber b<1> to a chamber t<3>, which communicates with a passage e leading to the press cylinder. High-pressure passages d, f communicate with chambers 2, b<1> respectively. When the pressure in the press cylinder is such that its effect on the ram through the chamber t' balances that of the high pressure in the chamber 2, the high pressure in the chamber b<1> opens the valve w<1> and passes to the cylinder.

Abstract: 547,948. Gauging-apparatus. MOLINS, D. W., BEST, C., and MOLINS MACHINE CO., Ltd. March 13, 1941, No. 3438. [Class 106(ii)] An article after a dimension test is moved over two movable pivoted guide members arranged in succession and held by catches which are released according to whether the article tested is over or under the tolerance allowed so that the article is discharged into a "high" or "low" receptacle. Cartridge cases 30 are fed down a runway 31 and taken one at a time by a transfer member Tl as described in Specification 547,947, [Group XXX], on to a support R1 formed by two spaced V-plates where they are gauged for length as described in Specification 544,478. By the time the gauging operation is performed, the member T1 is transferring another case to the support R1 and the leading horn of the member pushes the gauged case on to flaps 63, 64 forming a path to the next gauging station. These flaps are curved with a radius centred from the shaft 33 of a second transfer member T2 and are pivoted on shafts 65, 66. These shafts carry arms engaging under spring-pressed sliding rods held by catches. The flaps either drop under their own weight or although remaining up when not loaded, will drop when carrying a case. The gauging at station R1 is for length and the catch for long cases releases flap 63 and for short cases flap 64, cases of correct length being transferred to a further station for a further gauging operation.

Title: Apparatus for use in connection with the stabilisation of ships
IPC: G05D1/08
Filed: 1961-01-30
Abstract: 977, 390. Automatic ship stabilization. SIEMENS SCHUCKERTWERKE A. G. Jan. 30, 1961 [Jan. 29, 1960; April 14; 1960], No. 3526/61. Heading G3R. In a system for stabilizing a ship, the angle of motor-driven fins is controlled automatically by the difference between a signal from an attitude reference and a signal, dependent on fin angle, which, over a higher speed range of the ship, is made greater in dependence on the speed of the ship. In Fig. 1 a signal general 1, energized from an A.C. source 3 through a booster transformer 2, is arranged, in a manner not shown, to generate a signal, dependent on fin angle, which is fed back to a system (not shown) automatically controlling the fin to stabilize the attitude of the ship. The signal so fed back is made to vary in a non-linear manner with speed of the ship by supplying the primary of transformer 2 from a controlled magnetic amplifier 4. At low ship speeds an input winding 6 of the magnetic amplifier has a constant energization from a source 9 and a further positive feedback winding 13 of the magnetic amplifier has constant energization through a resistor 14 responsive to a heater 15 energized from source 9. Above a predetermined speed the voltage of a source 10 which is dependent on the speed of the ship overrides that of source 9, by virtue of rectifiers 7, 8, so that the energization of windings 6 and 13 are also dependent on ship speed to produce the necessary non- linearity in this range. In a modification a pair of tachometer generators associated with the ship's propeller shaft are connected in cascade to develop a signal, dependent on the square of ship speed, which is used to modify the position feedback signal from the fin. An electrical signal dependent on the square of ship speed may alternatively be derived from the dynamic fluid pressure of a Pilot head.

Title: Improvements in or relating to halogenated dicyclopentadiene epoxides
IPC: C07D303/10
Filed: 1952-02-11
Abstract: The invention comprises compounds of the formula <FORM:0714869/IV (b)/1> where X is chlorine or bromine and Y is a fluorine, chlorine or bromine atom.  The products, which can be described as 1 : 4 : 5 : 6 : 7 : 8 : 8 - heptahalo - 2 : 3 - epoxy - 4 : 7-methano - 3a : 4 : 7 : 7a - tetrahydroindanes may be prepared by forming the 1-halo derivative of the Diels-Alder adduct of cyclopentadiene and a hexahalocyclopentadiene, converting this to the 2 : 3-chlorohydrin by the action of a hypohalous acid, suitably by adding an alkyl hypohalite in the presence of an organic acid and dehydrohalogenating this, e.g. by the action of sodium hydroxide. The preferred products are those obtained from the adduct of cyclopentadiene and hexachlorocyclopentadiene (chlordene).  In examples: (1) 1-chlorochlordene is treated with tertiary butyl hypochlorite in acetic acid, and the resulting chlorohydrin acetate is treated with hydrogen chloride in methanol to give the free chlorohydrin which is treated with sodium hydroxide to give 1 : 4 : 5 : 6 : 7 : 8 : 8 - heptachloro - 2 : 3-epoxy - 4 : 7 - methano - 3a : 4 : 7 : 7a - tetrahydroindane, and (2) 1-bromo-4 : 5 : 6 : 7 : 8 : 8 - hexachloro - 4 : 7 - methano - 3a : 4 : 7 : 7a-tetrahydroindene is used in place of the 1-chloro-compound in the process of (1) to give the same product as in (1) due to preferential elimination of hydrogen bromide taking place.  The corresponding epoxide of 1-fluorochlordene is made by using 1-fluorochlordene in place of the 1-chloro-compound in example 1 and the epoxide of 1-bromochlordene is made by using tertiary butyl hypobromite in place of tertiary butyl hypochlorite in example (2).  1-Bromochlordene is made by treating chlordene with bromine in the presence of an organic peroxide.  1-Chlorochlordene is made by hydrolysing 1-bromochlordene to 1-hydroxychlordene which is chlorinated with thionyl chloride.  1-Fluorochlordene is made by heating 1-bromochlordene with mercuric fluoride in hexane.ALSO:Insecticides comprise compounds of the formula <FORM:0714869/VI/1> where X is chlorine or bromine and Y is a chlorine, bromine or fluorine atom, especially the compounds in which X is chlorine (see Group IV(b)), in admixture with a carriers such as solvents, dusts or emulsifiable concentrates and optionally combined with other active ingredients.
