Abstract: 1,185,252. Spray producers. PARKERHANNIFIN CORP. 4 March, 1968 [8 March, 1967], No. 10443/68. Heading B2E. A spray nozzle comprises a nozzle body assembly defining a liquid passage which includes a vortex chamber having spin slots leading thereinto and having a discharge orifice from which a whirling liquid emerges as a hollow conical spray. The body also includes a variable area valve inwardly adjacent the vortex chamber, comprising a flexible diaphragm having a central opening coaxial with the discharge orifice, the diaphragm being flexed away from a seat in the assembly under a predetermined increase in pressure of liquid behind said diaphragm to form an annular orifice through which liquid flows into the Vortex chamber to augment the flow of liquid through the spin slots, one side of the diaphragm and seat forming a wall of the vortex chamber, the other side of the diaphragm being exposed to pressure of the liquid in the liquid passage. An embodiment of the invention in the form of a fuel spray system, is illustrated in Fig. 2, wherein liquid fuel flows through the outer groove 16 in a spacer 11 and through openings 18 in a diaphragm 10 to an annular groove 19 formed in the inner face of an orifice plate 9. This plate is provided with tangential spin slots 23 which impart of whirling motion to the fuel as it passes into the periphery of the vortex chamber constituted by recess 21. When the pressure of the liquid fuel exceeds a predetermined value, the diaphragm will flex away from the seat 27 to provide an additional flow of liquid through the annular space so-formed, to augment the flow of liquid through the spin slots.

Title: Automatic overload safety device
Inventor: BAUER WALTER
IPC: B66C23/90
Filed: 1962-03-22
Abstract: 941,226. Hydraulically operated devices for preventing overloading in cranes. INSTITUT FUR FORDERTECHNIK LEIPZIG. March 22, 1962, No. 11104/63. Heading B8B. An overload device 5 controls lowering of the jib of an hydraulically operated crane, overloading being prevented by valves 7, 11, which are closed by the hydraulic fluid when its pressure reaches dangerous limits, to prevent further movement of fluid and thereby arrest the jib. Fluid returning to a reservoir from a luffing ram 3 passes through a control valve 2 and a conduit 6 to the overload device 5. In the device 5 the fluid passes through a spring- loaded throttle valve 7, a chamber 8 restricted by an adjusting screw 9 and a discharge valve 11, held open by a spring 14, to a conduit 12. If pressure in the discharge conduits rises to too high a value, fluid in a conduit 15 closes the valve 11 by urging it upwards and the valve 7 is pushed downwards into a closed position by pressure fluid in a conduit 16. The tension of springs 13, 14 is adjustable. A further conduit 17 is connected to winch overflow valves, which are closed when the pressure in the system is too high, thereby stopping the winches. The valve 11 may be housed in a separate block which may be either attached to or separate from the block 5. When the overload limit is reached during raising of the jib an overload valve 4 opens and no further upward movement is possible.

Copper-plating baths are improved by adding a basic dyestuff which contains an ethenyl chromophore i.e. one or more groups > C = C < and nitrogen, e.g. cyanine, acridine, pyronine, quinoline, tri-phenyl methane, thiazole, and thioflavine dyes. These act as levelling agents at low current densities. There may also be present lustering agents, e.g. N mono- or disubstituted dithiocarbamic acid alkyl ester sulphonic acid, 1.3.5-triazine-2.4.6-tris-mercapto alkane sulphonic acid, thio amides and iso thio amides having a sulphonic group. In addition, to render mains water usable, there may be added amino compounds free of carboxyl groups, e.g. N: N-dimethyl bromaniline, 3-diethyl amino-1-chlorpropanol 2, and halogen salts of quaternary ammonium compounds. Wetting agents, e.g. polyethylene oxide addition products may be present. The deposition of anode mud is prevented by adding sulphonic acid salts, e.g. Na salt of azido-propane sulphonic acid. In examples, the dyestuffs added are thioflavine, p-dimethyl-amino-triphenyl carbenium chloride, 3-3<1>-diethylthiocyanine iodide thiopyronine and an indolenine dye.

Title: Apparatus for monitoring rotation
IPC: G01P3/26
Filed: 1974-03-13
Abstract: 1462961 Speedometers: Speed sensor  W von WEIZENBECK 13 March 1974 [14 March 1973] 11178/74 Headings G1K and G1N To monitor the speed of a rotating disc 11, e.g. a brake disc of a vehicle, a sensor 13, 41, or 47 is resiliently mounted with a face 15 close to a surface of the disc 11, the opposed surfaces having sufficient roughness for the rotating disc to entrain an air-stream past the face 15 of the sensor and cause the sensor to be displaced on its resilient mounting, and means responsive to the displacement providing a signal dependent on the rotational speed of the disc the area of the sensor surface facing the disc being substantially less than the area of the disc surface to which the sensor is pre- - sented. The signal producing means is an electrical resistance strain gauge array coupled to a bridge circuit, or Piezo-electric or magnetostrictive strain gauges. In Figs 1, 3, two sensors in the form of pins 13, 14 mounted on leaf springs 20, 19 on a yoke 16, 17, 18 have faces 15 adjacent opposite sides of the disc 11. Stops 16a, 17a prevent the pins from touching the disc. The yoke is mounted on a leaf spring 24 with strain gauges 27, 28 on its two sides. Entrained air as the disc 11 rotates in direction P 1  deflects the sensors and yoke in direction P 4 . The spring 24 may be cantilevered from a chassis member 26, or from the brake yoke carrying brake pads adjacent the disc Figs. 6, 7, (not shown). In Fig. 8 a holder 42 on the brake yoke 33 carries a sensor pin 41 so that its end-face is adjacent the rim of the disc 11. Entrained air deflects the pin 41 radially of the disc, the resultant bending of the leaf spring 43 being measured by strain gauges 44, 45. In Fig. 12, the end face of the sensor pin 47 again faces the rim of the disc 11, but the transverse mounting of the holder 48 on a leaf spring 50 means that the sensor and its holder are deflected tangentially of the disc. In a vehicle braking system, the sensor pins preferably are retracted clear of the disc except when braking takes place.

Abstract: 789,575. Weighing apparatus. S.A.S.I.B., SOC. PER AZIONI SCIPIONE INNOCENTI-BOLOGNA. April 12, 1956 [April 13. 1955], No. 11226/56. Class 143 An apparatus for recording the weights of batches of cigarettes extracted at intervals from a cigarette making machine (not shown), marks a chart 56 (Fig. 13), with lines C which are arranged in columns, each corresponding with a batch weight falling within a predetermined range, the length of each line indicating the number of batches failing within the associated range. A cam mechanism (Figs. 3 and 9, not shown), driven in timed relation with the machine, causes a bar 80 (Figs. 7 and 8). to press an arm 13. pivoted about an axis 15 on the weigh beam 3. against one of a series of lugs 77 carried by arms 72 pivoted about a' common axis 73. The consequent movement of the engaged arm steps the associated ratchet wheel 67 which. through gearing 66. 65. 63. 60 moves the associated marker 50 upwardly over chart 56. At the same time bar 80 steps a further ratchet wheel 171 (Fig. 8) which. through similar gearing, moves a further marker to produce a line N (Fig. 13), the length of which indicates the total number of weighings. The markers 50 are provided with indicating pointers 53 which project through vertical slots in a stationary calibrated plate 55. The cam mechanism is arranged to move the chart horizontally after a predetermined number of weighings to produce horizontal interruptions in in the lines C and N which, when joined by dotted lines as shown in Fig. 13. produce a set of distribution curves of the weights of the batches produced by the machine The gearing chain 60 driven by the ratchet wheel 171 carries a projection 106 which engages a switch operating arm 107 when the associated marker is at the top of the chart and thereby renders the apparatus inoperative until it is reset. The weigh pan 8 (Fig. 11), which is supported from the weigh beam 3 by a rod 10 is provided with a pivoted base member 27 which is moved to the dotted line position to discharge the weighed batch by a spring loaded lever 29 movable by a rod 32 which is reciprocated by the cam mechanism and which also serves to lock the beam in its container 1 and a reciprocating piston 7. is contained in a case provided with locking mechanism which when unlocked automatically frees the wheels 67, 171 and allows the markers to be reset. Beam 3 is also provided with a weight indicating pointer 11 and a damper 18, 19. In a modification (not shown). levers 72 operate micro switches-which control the operation of the cigarette making machine. In a further modification (also not shown), the markers are controlled by electric devices which are energized by switches operated by either the pointer 13 or the arms 72.
