Title: Water sprinkler
IPC: A01G25/09
Filed: 1972-04-18
Abstract: 1393581 Water sprinklers H R DI PALMA 18 April 1972 [19 April 1971 13 April 1972] 17849/72 Heading AID [Also in Divisions B8 D1 and F2] A water sprinkling appliance comprises a sledge carrying a rotary sprinkler nozzle, and a wheeled frame having a hose which is wound onto a reel, itself intermittently driven by a water activated double acting jack. In operation the sledge is spaced from the wheeled frame and moves towards it as the hose is wound onto the reel. In a preferred embodiment the speed of rotation of the chain is controlled according to the amount of hose wound thereon and the water supply is automatically cut-off once the sledge has been wound onto a ramp which is mounted on the wheeled frame. In a first embodiment (Figs. 2-3) the drum 1 is mounted on a rotatable turret 3 which carries a ramp 13 up which the sledge 11 moves so as to rest on a bracket 12 when reeled in. Water is fed to a hose 10 via pipes 103, 104 and the other end of the hose is connected to a tube 26 mounted on the sledge and carrying a rotary sprinkler nozzle at its upper end. The drum 1 is intermittently driven by the rod of a double-acting jack 16 to rewind the hose which is guided onto the drum by a stirrup 231, reciprocated along a guide rod 233 by a screw threaded rod 234 see also Divisions B8 and Dl. In a second embodiment (Fig. 16) (see also Figs. 9-14 not shown) water is supplied to a double acting jack 315 via a two-way valve 325 which is controlled by a two position valve 324, moved between these positions by an arm 327 pivotally mounted on a rod 326 which is connected to the rod 316 of the jack 315. A lever 335 is urged by a spring against the hose coils on the drum and is connected via a linkage 334 to a flow control valve 336 and closure valve 332 in the water circuit to the valve 325. As the lever 335 is deflected due to the increasing diameter of the coils the valve 336 is closed to reduce the water flow rate and hence reduce the speed of rotation of the drum so as to maintain the ground speed of the sledge constant. The valve 332 is closed and the water supply cut off, if the deflection of the lever 335 exceeds a certain limit due to uneven rewinding of the hose. A cable 331 extends across the ramp so that when the sledge climbs it, a lever 329 of a valve 328 is tripped and the valve 328 cuts off the water supply to the jack 315 and feeds water to a jack 314 which then raises the ramp. Upon the ramp reaching a raised position, a linkage opens a discharge valve 341. The hose is guided onto the drum by a stirrup which reciprocates along a screw threaded transverse rod which is rotated by a pawl and ratchet mechanism (see also Division F2) driven by the lever 326. A linkage associated with this mechanism reverses the direction of rotation of the rod when the stirrup abuts either of two stops, each at one end of the screw thread.

Abstract: 1,144,441. Microwave amplifying circuits. GENERAL ELECTRIC CO. Ltd. 28 April, 1966 [28 April, 1965], No. 17861/65. Heading H3T. In a microwave amplifier, having a tunnel diode 9 or other negative resistance element connected by a transmission line 5 to one port of a circulator 3, a first stub transmission line 26 is effectively connected in parallel with the tunnel diode or other element across the transmission line so as to balance out the reactive impedance associated with the diode or other element and a second stub transmission line 30 is connected across the transmission line between the circulator 3 and the first stub such as to increase the bandwidth of the amplifier. The stubs 26, 30 are spaced apart by a quarter of a wavelength and a further stub 29 similarly spaced can be included to ensure stability of the amplifier. In order to prevent the amplifier arrangement from oscillating the input and output paths 1 and 2 of the circulator 3 may contain an isolator. The circulator may be a 5 port device having two ports resistively terminated. Mounting.-The tunnel diode 9 is mounted between the transmission line 12 and a metal member (14, Fig. 3, not shown), which is held in place by a spring (21). The member (14) forms with the block 11 an auxiliary transmission line and insulation tape 16 such as polytetrafluorethylene is provided between them. The bias source (23) is connected to the tunnel diode via a disc (19), a rod (17) surrounded by lossy material (18), such as synthetic resin loaded with iron powder and the member (14). A resistor (25) which may form part of a potentiometer chain is connected between the disc (19) and the block 11. The construction of the microwave amplifier forms the subject of Specification 1,144,442.

Title: Improvements in or relating to clocks or clock movements
IPC: G04C15/00
Filed: 1934-06-16
Abstract: 439,830. Electric clocks. POLLAK, J. E., 20, Holborn, London.-(Sangamo Electric Co. ; Springfield, Illinois, U.S.A.) June 16, 1934, No. 17900. [Class 139] In clocks, time switches, prepayment and demand meters, and other apparatus including a timing mechanism wherein the time shaft is normally driven directly by a synchronous motor and an auxiliary mechanism wound by the motor drives the movement during current stoppages, the auxiliary movement takes over the drive automatically when the speed of the motor falls below the lower limiting rate allowed for by the A.C. supply. The auxiliary mechanism is controlled by an escapement which is forced to oscillate at a rate higher than its natural period while the motor is driving the time shaft, and, if it fails, stops the time shaft. The invention, as applied to a clock, comprises a self-starting synchronous motor 5, for example, as described in Specification 377,696, [Group XXXV], driving through worm gearing, or, as shown, through gearing 14, 15 ... 24, a wheel 25, which drives a disc 66 through gearing 51 ... 55, 57, 64, an adjustable friction clutch 58 being interposed between gears 55, 57. A pinion rigid with wheel 25 rotates a barrel 9 to wind the auxiliary main-spring 26 therein which through gearing 33, 34 drives a time shaft 7 carrying a hand 6 the other hand being driven through gearing 8. The gear wheel 34 is connected through gears 35 ... 39, shaft 41, and gears 42 ... 45 to the escapement 10. The spindle 41, also carries a ratchet wheel 71 engaging a slotted spring 69 carried by a rod 68 secured to the disc 66. Normally the hands are driven by the motor through gearing 14 ... 25, 51 ... 55, the clutch 58, gearing 57, 64, blade 69, ratchet wheel 71, shaft 41 and gearing 39, 38 ... 34. The escapement is adjusted, " slightly slow " and is driven by the motor at a frequency slightly greater than its natural frequency. The spring 26 is also maintained wound by the motor, overwinding being prevented by a frictional connection between the spring and the barrel obtained by inserting leaf springs between the outer convolutions of the main-spring. Alternatively, a slipping clutch may be interposed between the gears 28, 29 to prevent overwinding. Should the speed of the motor fall below the lower limiting rate allowed for by the A.C. supply, for any reason, the drive is taken over by the mainspring 26 under the control of the escapement 10, the ratchet wheel 71 rotating idly past the slotted spring pawl 69. If, while the motor is driving the hands, the escapement 10 should stop, then the hands 6, being geared directly thereto, stop to indicate the failure of the auxiliary mechanism, and the clutch 58 slips to prevent stoppage of, and harm to the motor. In time switches, demand meters &c., the failure may be indicated by the stoppage of a target normally moved by the shaft 7.

Abstract: 835,741. Electron beam deflecting apparatus. TELEFUNKEN G.m.b.H. June 14, 1956 [June 23, 1955(2)], No. 18404/56. Class 39(1). [Also in Group XXII] Electromagnetic deflecting coils for cathoderay tubes comprise saddle coils 2 and 3, which are preferably cosine coils, for horizontal deflection of the electron beam, and two oppositely disposed toroidal coils 5 and 6 mounted on a ferromagnetic yoke 4 surrounding the saddle coils, for vertical deflection of the beam. Each of the toroidal coils overlaps some of each of the two groups of longitudinal conductors of one of the saddle coils and preferably covers an arc which subtends an angle of at least 90 degrees at the centre of the coils. The marginal sharpness of the picture on the cathode-ray tube screen is improved both by the use of cosine coils and by the fact that the yoke may be relatively small as the crosssectional area of the windings of the coils 2 and 3 diminishes in the region of overlap sufficiently to accommodate the toroidal coils. The saddle coils may be disposed within a hollow plastic cylindrical member 9 having indentations 10 in which the yoke and toroidal coils are disposed. The yoke may be manufactured in two or four portions which are held together by means of a metal band 11, the whole being coated with an insulating layer.

Title: Pneumatic anti-skid devices
IPC: B60T8/50
Filed: 1971-06-01
Abstract: 1356845 Anti-skid device KNORR-BREMSE GmbH 1 June 1971 [1 June 1970] 18463/71 Addition to 1335916 Heading F2F A pneumatic anti-skid device for use in a vehicle braking system which has a skid sensing means connected to the device is, in use, connected in the braking line and allows braking pressure build up for normal applications until a skid is sensed whereby the device brings about a throttled reduction of braking pressure and then permits a subsequent increase in. braking pressure at a rate less than the build up of braking pressure during normal braking applications. The pressure builds up to a steady state pressure which is less than that at which skidding was sensed, the lower the "skid" pressure the higher the pressure difference between the "skid" pressure and the steady state pressure. The device is shown in its rest position whence fluid pressure can pass through chambers 58, and 39 to the brake cylinder 7 for normal application of the brakes . On a skid being sensed a solenoid operated valve 29 is actuated to close off a vent 32 to atmosphere and pressurize a chamber 20 from a reservoir 5 to depress a piston 14 hence closing a valve 46, 47 in the brake fluid supply circuit and opening a venting valve 18, 47, braking fluid passing to the atmosphere through a throttle 19. Reservoir pressure also flows into a chamber 11 which has a throttled outlet 12 to atmosphere through grooves 38 in the rod 17 of piston 14. With the depression of the piston a throttling piston 51 is spring urged into a passage in the brake fluid supply circuit. After the skid has ceased the solenoid operated valve is de-actuated so that chamber 20 is vented which allows piston 14 to rise under its spring loading until it engages a floating piston 21 which has been depressed by the residual pressure in chamber 11. Valve 18, 47 is closed and valve 46, 47 opened but since the rise of piston 14 is limited the throttling piston 51 still throttles the flow of braking fluid to the brakes, hence the build up of braking pressure is at a rate less than normal build up. The valve seat 46 of valve 46, 47 is provided on a spring loaded piston 41 an annular chamber 42 surrounding the piston 41 being in communication with the braking circuit through a one way valve constituted by the peripheral seal of the piston 41. Thus chamber 42 is substantially at the initial braking pressure. When pressures on both sides of the piston 41 are equalized the piston 41 moves upwardly so that the valve 46, 47 is closed and the steady state pressure is achieved in the brake cylinder until such time that the pressure in chamber 11 decays sufficiently to allow the pistons 14 and 21 to rise and thus open valve 46, 47 and remove the throttling piston from the passage. The time spent by the device in its "steady state pressure" state becomes less as the initial braking pressure increases.
