Abstract: 1318404 Ultrasonic flow measuring J-TEC ASSOCIATES Inc 3 Sept 1970 [12 Sept 1969] 42305/70 Heading H4D Apparatus comprising a strut mounted in a fluid flow path for causing disturbances therein, a transmitter transmitting sonic waves towards said disturbances and a receiver receiving said waves modulated by said disturbances. A transmitting transducer directs ultrasonic energy across the path of a karman vortex trail, shed from a cylindrical rod. A receiving transducer lies either in the path of the beam and detects interruptions thereof or is slightly displaced downstream, receives refracted energy and detects increases in received signal amplitude. The received signals are de-modulated and the resulting pulses counted digitally to provide a measure of the fluid velocity. A single transmit-receive transducer may be mounted on the vortex strut and direct the sonic energy downstream. By using a range gate the passage of a vortex through a particular point may thus be detected from the received echoes. The vortices may be formed by a cylindrical strut mounted on a base-plate with the transducers mounted on laterally displaced aerofoils downstream thereof (Fig. 4, not shown). Alternatively the strut may take the form of a ring (Fig. 6, not shown) with the transducers supported above and below the plane thereof, forming an omnidirectional velocity sensor. The device may be used on aircraft for measuring airspeed and automatic control or on stationary buoys for measuring current.

Abstract: 877,366. Adjustable seats. DAVIES, J. A. Dec. 15, 1959, No. 42614/59. Class 52(2). [Also in Group XXV] In an adjustable locking hinge of the pawl-andratchet type for folding furniture the pawl, in the closed position of the hinge, is automatically freed from the position for engagement with the ratchet teeth to enable the hinge to be freely moved from closed to open position, and when the hinge is open the pawl is automatically returned to the position for engagement with the teeth. The spring loaded pawl 19 is located between the arms of the U-shaped hinge member 17 and has a stem 20 slidably mounted in the end 171 of the member and a peg 24 which extends from each side of the pawl through slots 22 in the arms of the member, each slot being provided at its end farthest from the hinge pin 18 with a notch 23. By moving the member 17 towards the closed position of the hinge the pawl is caused to ride over a cam surface 15 on the other hinge member 12 so that it is pushed back against the action of the spring 21. On reaching the closed position the pawl abuts a stop surface 16 and is pushed sideways so that the peg 24 engages in the notches 23 and holds the pawl clear of the teeth so that the hinge can be freely opened. On reaching the open position the pawl abuts the end tooth 14, which is longer than the others, and is pushed sideways to disengage the peg 24 from the notches whereupon it again engages the teeth. The ends of the peg are provided with knobs 25 which may be pressed to manually retract the pawl. A pivoted latch 26 (Fig. 5, not shown) may be provided on the member 17 to prevent accidental disengagement of the pawl from the ratchet teeth.

Title: Method and machine for stripping pulp bales
IPC: D21D1/00
Filed: 1975-10-22
Abstract: To break up entire fibre bales into individual fibres or small fibre flakes, a fibre bale (1) is moved continuously by a conveyor band (3) towards groups of moving fibre-opening tools (6, 7) which, during the advance of the bale, make a number of vertical parallel grooves in the surface (2) of the fibre bale located at the front in the direction of movement. The fibre-opening tools are individual tools cooperating with one another in pairs and having differently pointed fibre-stripping tips, a tool which has a relatively acute-angled stripping tip making a relatively narrow groove in the said surface of the fibre bale. This is followed continuously in the work cycle by a tool having a relatively obtuse-angled stripping tip which widens the narrow groove made previously and, at the same time, removes further fibre material from the surface of the fibre bale located at the front, the groove walls being broken down. The break down of the groove walls is assisted by the mutual offsetting of successive tools. <IMAGE>

Abstract: 1496343 Solenoid- and fluid-operated brake valves; brake systems LUCAS INDUSTRIES Ltd 11 Sept 1975 [11 Oct 1974] 44114/74 Heading F2F A solenoid-operated hydraulic brake pressureregulating valve assembly 9, Fig. 1, used in an electrically-driven vehicle incorporating regenerative braking, comprises a housing having an inlet 32, Fig. 2, connected to a master cylinder 6, Fig. 1, an outlet 28 connected to electricmotor-driven wheels 1, 2, and a solenoidoperated valve 42 and a pressure-responsive valve 43 located in parallel between inlet and outlet; valve 42 is closed when regenerative braking is operative, but otherwise is open, and valve 43 is normally open but closes after valve 42 has closed but then only after inlet pressure has attained a predetermined value. In operation, when pedal 21 is depressed, brakes on non-driven wheels 4, 5 have their clearances taken up, and at the same time a potentiometer 20 and associated apparatus simultaneously establish regenerative braking and energize solenoid 15 to close valve 42. Fluid from master cylinder 6 passes through still-open valve 43 to take up braking clearances on wheels 1, 2, at which point pressure in a counterbore 36 acting on a shoulder on piston 49 at the lower end of a reduced portion 53 urges piston 49 downwards, so a valve head 52 engages a seating 54 (these constituting the operative parts of valve 43). Inlet 32 is thus isolated from outlet 28. When the speed of the vehicle falls to, e.g. 10 m.p.h. at which regenerative braking is not in operation, solenoid 15 is de-energized, so valve 42 opens. If the brakes are applied at vehicle speeds below 10 m.p.h., there is unrestricted flow through valve assembly 9. Should regenerative braking fail, the system operates as a normal system. When greater deceleration is required, a situation arises where both valves 42, 43 are closed, but a piston 29 is forced down against a spring 30 to pressurize trapped fluid between the valves and the actuators of brakes 1, 2, which are thereby applied.
