Title: A new or improved ball projecting appliance
IPC: A63B69/40
Filed: 1937-08-21
Abstract: 500,440. Ball-projecting appliances for games etc.; line - throwing apparatus. RICHARDSON, S., and PARKS, H. A. Aug. 21, 1937, No. 22971. [Class 132 (ii)] [Also in Group XXI] Relates to a ball-projecting appliance for games or sports or for rescue work, of the kind wherein a hitting element operated by a spring propels the ball from a ball-positioning member, and consists in making the hitting element in the form of a pivoted kick lever, arranging the spring to operate torsionally and holding the hall, for example by a slight gripping pressure, in a ring, flange, rim or the like. As shown for projecting footballs, the appliance comprises a direction delivery element or ball guide B rigid with a frame 8a and pivoted by means of a rod 69, on a cross-shaped supporting frame 58, 59. The inclination of the ball guide may be adjusted by an apertured link 70. A kicking or hitting lever D is pivoted at the upper end of the frame 8a on a shaft 20 and is connected to one end of a helical spring 23, Fig. 5, acting torsionally, the other end of the spring being secured to a hand-lever 44 which may be set in any of the notches 46 to vary the power of the spring. In using the appliance, the kicking lever D is drawn back by means of a handle 83 thereon, or by means of a pedal 84 and chain 90 co-operating with a wedge 96 and clutch 86, and is retained in the raised position by a pawl 28 and ratchet wheel 26. On releasing the pawl by means of a hand-lever 33 the spring 23 turns the kicking lever so that a striking pad 53 thereon projects the ball a up the guide B and through the air to the awaiting player. The ball when. placed in the ball guide runs down'to a gapped ring 3 where it is held by a slight gripping pressure. The kicking lever D after passing through the gap in the ring is cushioned by a buffer spring at the upper portion of the support 8a. Trough-like magazines at the sides of the ball guide B contain a supply of balls, and may be swung over the ball guide when the apparatus is out of use. Spin may be imparted to the ball by adjusting the striking pad 53 to an eccentric position on the kicking lever, or by adjusting the pivotal axis of the kicking lever, or by employing tapered baffles in the ball guide B so as to receive a glancing blow from the passing ball. A guard may be arranged around the kicking lever'and arrangements may be provided whereby liberation of the kicking lever cannot be effected until the guard is in place. The apparatus may be used for rescue work in water by projecting an inflated ball attached to a cord or line, or in the event of fire the line may be projected over a building.

Title: Improvements in or relating to grounded flight trainers
Inventor: GREENHALF WILLIAM DOUGLAS GEOR
IPC: G09B9/30
Filed: 1958-07-17
Abstract: 930,131. Grounded aircraft trainers. GENERAL PRECISION SYSTEMS Ltd. July 17, 1959 [July 17, 1958], No. 23039/58. Class 4. Apparatus for simulating the external scene in grounded flight training apparatus comprises a model mounted to travel in a horizontal direction (the Y-axis) towards a television camera or other optical observation device which normally views in a direction generally opposite to that in which the model travels, and is arranged in a system projecting an image of the model in front of a trainee, the camera being movable in a plane at right angles to the Y-axis and movable angularly so that its movement relative to the model simulates movement of an aircraft during landing, take-off, and taxying procedures, wherein means is provided for moving the camera in the Y-axis direction as simulated altitude changes, and for correcting the Y-axis movement of the model in accordance with that of the camera so that the latter movement is not reflected in the image presented to the trainee. In the apparatus shown, a model of an airport is made on an endless band 11 movable over a table 12 in the Y-axis direction of the arrow by a drive shaft 17 and a pulley 13. A television camera 16 is movable laterally of the band, and vertically, and is angularly adjustable so that the image presented to a trainee by a projection device (not shown), simulates movement of the external scene in response to movements of dummy controls operated by the trainee and providing inputs to a flight computer. Normally, the camera is located over the part of the band 11 near pulley 13, as shown in full lines, so that before landing approach, and after climb after takeoff, simulation, the camera views the maximum horizontal length of the band and the image presented to the trainee simulate maximum forward visibility. As the simulated altitude decreases during landing approach simulation, the camera is moved longitudinally of the band by a drive shaft 18, either manually or automatically by the flight computer. Drive shaft 18 is connected to a differential 14 in drive shaft 17, so that the relative positions of the camera and band remain unchanged when shaft 18 rotates. On simulated landing, the camera 19 is at the centre of the band, as shown in broken lines, so that during ground manoeuvres, the visual scene in all directions can be projected. For example, if steering the aircraft through 180 degrees is simulated, the camera 16 is similarly rotated, and visual scene corresponding to half the horizontal band length is projected. As simulated height increases after take-off, the camera is returned to its station over pulley 13, so that the forward visibility shown in the projected image reverts to a maximum.

Title: Improvements relating to elastic fluid turbine governing systems
IPC: F01D17/26
Filed: 1929-07-26
Abstract: 316,615. Associated Electrical Industries, Ltd., (Assignees of Bryant, 0. N.). Aug. 1, 1928, [Convention date]. Regulating.-A regulating system for an elastic fluid turbine in which fluid can be extracted from or supplied to an intermediate point, comprises a governor for the inlet valve, with a fluid pressure relay for altering the setting of the governor according to the conditions prevalent in the turbine, an interstage valve between the high pressure and the low pressure sections, and an electrical relay when the turbine operates a generator. The governor 14, mounted on the turbine shaft 15, communicates with the cylinder 17 and provides a fluid pressure varying as the square of the speed of the turbine, on the piston 16, the rod of which operates the inlet valve 11 of the turbine 10, through the pivoted lever 18. To vary the setting of the governing arrangement, a variable back pressure is imposed on the piston 16 in opposition to the pressure from the governor 14 by the orifice 23 in the piston, conduit 24 and relief valve 25. The valve 25 is regulated by the turbine in the following way. Its diaphragm 27 is influenced by a head of mercury in the tube 28. This head is increased or diminished by the fall or rise of a rod 29 rigidly secured to the rod 33 actuated by the grid valve 13 between the high and low pressure stages 8, 9 of the turbine. The flow of steam from one stage to the other therefore adjusts the back pressure on the piston 16 to control the main admission of steam to the turbine. If steam is extracted or supplied to the pipe 12 between the stages, the pressure in the auxiliary pipe 52 causes the diaphragm of the valve 49 to raise or lower the rod 45 which raises or lowers the rod 35 of the pilot valve 39, 41 to admit steam above or below the piston 32 of the valve 34; this lowers or raises the rod 33 to actuate the relief valve 25 in the same way as before. When the turbine operates an electric generator, a solenoid 58 is connected to the line leads 59 of the generator to actuate an armature 56 to cause a valve 53 to vary the pressure on the upper side of the diaphragm of the valve 25 to admit the governing device and to the steam admission, to the load on the turbine.

Title: Derivatives of 3-alkyl, 3-methyl-spiro-[benzothiazole-2,2-(2-h-1-benzopyran)]
IPC: C07F9/6561
Filed: 1960-07-01
Abstract: The invention comprises compounds of the formula <FORM:0887902/IV (b)/1> and their derivatives having in the 4, 5, 6, 7, 51, 61, 71 and/or 81 positions substituents selected from CH3, CH2CH3, CH(CH3)2, C(CH3)3, C6H5, CF3, CN, COCH3, CO2C2H5, CO2H, NH2, NHCH3, N(CH3)2, N(CH3)3+, NHCOCH3, NO2, PO3H-, OCH3, OC2H5, OCH2CH2CH3, OC6H5, OCOCH3, SCH3, SH, SCOCH3, SCN, SOCH3 (methyl sulphinyl), SO2CH3 (methyl sulphonyl), SO2NH2, S(CH3)2+, F, Cl, Br, I, IO2, CH2CH=CH2 and CO2CH3; these substituents are to be sterically compatible as defined below.  These compounds are colourless in solution, but on irradiation with blue to ultra-violet light the 21-11 bond is broken and the compounds are coloured; irradiation with green to infra-red radiation reverses the process.  "Sterically compatible" substituents are those which do not hinder the breaking of the 21-11 bond on irradiation.  The compounds in solution can be used to sensitize record materials for the recording and erasing of data by the appropriate radiation.  The compounds are prepared by condensing a suitably substituted salicylaldehyde with a suitably substituted 2-ethyl-3-alkylbenzthiazole; the latter may be obtained by alkylation with an alkyl p-toluenesulphonate. An example prepares 3,31 - dimethyl - 61 - nitro - spiro - (benzothiazole - 2,21-[21H,11-benzopyran]).

Abstract: 833,073. Fluid-pressure servomotor control systems. UNITED STATES STEEL CORPORATION. July 22, 1957 [Sept. 13, 19561, No. 23185/57. Class 135. [Also in Group XII] In a system for supplying oxygen to a blast furnace tuyere having a connection to a hot-air blast main, the amount of oxygen supplied to the tuyere is dependent upon the rate of flow through the air blast main and/or the tuyere, the arrangement preferably being such that the oxygen flow is inversely proportional to the air blast flow so that the total oxygen flow through the tuyere is substantially constant. In the arrangement shown, each tuyere 3 has an associated oxygen supply pipe 7 fitted with a regulating valve 10 operated by a fluid-pressure motor 12. The latter is controlled by a pivoted jet tube 18 whose end moves between the ends of the motor fluid supply conduits 24, the movements of tube 18 being controlled by diaphragm motors 15, 16 connected to Venturis 31, 34 in the blast main 2 and tuyere 3 respectively. The ratio of the forces applied by the motors 15, 16 may be varied by adjusting the position of a fuldrum 20, and a proportional control of valve 10 is provided by a lever 27 having an adjustable fulcrum 30, and connected at one end 28 to the valve-actuating mechanism and at the other to motor 16 through a spring 29. In the event of decrease of the air flow through the main 2, or the tuyere 3, e.g. due to partial obstruction by the furnace charge, the motor 12 is operated to cause the valve 10 to permit an increased flow of oxygen through the supply pipe 7. The diaphragm motor 15 may be omitted if desired.

Abstract: 660,278. Loading freight containers on vehicles. DOORNE, H. J. VAN. Sept. 3, 1948. [Sept. 6, 1947] No. 23290/48. Class 78 (iv). [Also in Groups XXV and XXXII] In a vehicle of the type in which a supporting frame for a load container may be pivoted rearwardly about a rear axis or forwardly about a forward axis. an interlock preventing errors in operation is provided between two manual controls, one for locking the frame against movement about either or both axis and the other selectively operating means for tilting the frame and for moving the container onto or off it. A container 31 is supported by rollers 33 on tracks 35 of a frame 30 normally carried in trunnions 40, 41 on the main frame 25 of a semitrailer 21, and the frame 30 may be pivoted about the trunnions 40 as shown in Fig. 2 or about the trunnions 41 as shown in Fig. 6 by a hydraulic jack 45. In the position shown in Fig. 2 the container 31 may be delivered to or received from a platform 28 above the normal level of the frame 30, while in the position shown in Fig. 6 it may be delivered to or received from a surface below that level, e.g. the ground. A doubleacting hydraulic jack 50 is connected by a rod 52 to the container to push or pull it onto or of the frame. As shown in Fig. 6 the half-bearings 42, 43 respectively on the frame 30 are normally locked in engagement with the trunnions 40, 41 on the semi-trailer by hooks 71, 75 controlled through link work 73, 74 from a lever 70 so that both the hooks are engaged when the lever 70 is in its central position and one hook only is disengaged by moving the lever 70. The valve controlling the jack 45 is operated by means which also turns a cam arranged to interfere with a member moved by link work connected to the lever 70 so that the jack 45 cannot be operated until either the hooks 71 or the hooks 75 have been disengaged from the trunnions 40, 41 and the hooks cannot be moved to their engaging positions while the jack is operated. The control valves for the jack 50 are operated by the same member as the valve for the jack 45 so that the jack 50 cannot be operated until one of the hooks is disengaged and the hooks cannot be re-engaged while this jack is operating. Bridging members 36 are arranged to telescope into the rails 35. The contents of a container held on the frame 30 may be discharged through an end door by tipping the frame beyond the position in Fig. 6 with the bridging members housed. An adjustable hook 61 (see Group XXV) for holding a container on the frame is described.

Title: Improved means for facilitating the topping up of electric accumulators
IPC: H01M50/627
Filed: 1945-09-11
Abstract: 598,674. Batteries. CHLORIDE ELECTRICAL STORAGE CO., Ltd., and GRAY, R. Sept. 11, 1945, No. 23423. [Class 53] An accumulator is provided with a filling opening b in one of the side walls and below the normal level of the electrolyte. The opening is normally closed by a plug which seals both filling openings if the accumulator comprises two cells. When the electrolyte requires topping up, the accumulator is tilted to remove the electrolyte from the filling opening and the plug is removed and replaced by a funnel d, the mouth.f of which may be in the same plane as the normal electrolyte level. With a two-cell accumulator the funnel has two outlets and is divided by a partition g which is slightly below the top of the funnel so that water must flow into both cells before it overflows from the funnel. Figs. 6 and 7 show a stand i for receiving an accumulator h which is to be topped up from a funnel k. The stand and funnel are both pivoted on an axle j through which water is supplied from a pipe m to the funnel by way of a stop cock q and outlet s. An overflow t leads to a trough u. Rigidly attached to the funnel is an arm o engaged by a spring n surrounding a rod y pivoted at z to the base of the apparatus. A stop p on the rod y limits the movement of the arm o. When an accumulator is to be topped up, it is placed on the stand when in an inclined position as shown in Fig. 6. In this position the stop p holds the funnel at a slight distance from the filling opening of the accumulator, and the stopcock q is closed by a spring r. The stand is then moved to the vertical position during which movement the opening b is brought into watertight engagement with the funnel and the cock q is opened by a fixed abutment w which engages the operating arm v of the cock. Water now enters the accumulator till the rising of the water in the funnel indicates that the correct amount has been added. The stand is then tilted to its initial position when the separation of the funnel from the accumulator allows the latter to be removed. Specification 598,673 is referred to.
