Title: A rope-actuated mechanism
Inventor: WALLACE EDWARD MORRIS
IPC: A01G3/033
Filed: 1984-02-28
Abstract: The invention discloses pruning apparatus of the compound action hook and blade type. At the upper end of a longitudinally-extending handle, a stationary hook is fixed and extends upwardly therefrom in a plane parallel to and offset from the longitudinally-extending plane of the handle. It defines a downwardly-facing arcuately-shaped limb-engaging-surface for engagement with a limb. There is a movable blade which has a cutting edge and is operable to be reciprocated in an intersecting manner through cutting and return strokes with relation to the engaged limb and to the limb engaging surface of the fixed hook. A lever is pivotally mounted relative to the hook and a link pivotally interconnects to each of the lever and movable blade. The hook and movable blade and lever and link are each disposed contiguous to a common vertical plane. A rope and pulley assembly operatively interconnects with the movable blade through the lever and link and has a free end extended to the lower extremity of the handle for effecting pivotal movement of the movable blade through the cutting stroke responsively to a manually effected pull. Spring means effects movements of the movable blade through a return stroke. An adjustable grip in the form of a manually engageable member has a sinuous opening therethrough for the extension of the rope thereinto and therethrough and therefrom in the slip free positioning and grasping of the grip relative to the rope for the facilitating of the application of a force on and substantially parallel to the rope.

Patent GB-2143330-A (GB)
Title: Flow measuring devices
Inventor: JAMES JOHN FREDERICK COLSTON
IPC: G01F1/24
Filed: 1984-06-21
Abstract: A fluid flow measuring device includes a body 10 defining a fluid inlet 11 and an outlet 12 connected through a variable opening 17. The position of a valve member 18 is determined by a diaphragm 15 which is subjected on one side to the pressure at the outlet 12 and on its other side to a reference force generated for example by means of a constant force spring 16. As the pressure at the outlet decreases the valve member 18 is moved to increase the size of the opening and vice versa. The inlet pressure is maintained substantially constant by a similarly constructed pressure regulator 26. The position of the valve member 18 is sensed by a linear variable differential transformer 23 to provide an indication of the flow rate between the inlet and outlet. Non-linearities in the indication can be compensated by shaping opening 17 and/or member 18 or by correction with a computer. The reference force may alternatively be generated by a weight or bellows, or a variable rate spring, or a reference gas pressure; in one example a rolling diaphragm is subjected to force from a second such diaphragm exposed to a reference pressure. Compensation for gas temperature is possible using a spring or bellows. <IMAGE>

Title: Lamp housing for signs
Inventor: SHUTE GRAHAM
IPC: G09F13/04
Filed: 1986-08-26
Abstract: A lamp housing for signs comprises an open-ended tube 1 of translucent extruded polycarbonate having a one-piece side wall 2 of circular cross-section. The ends of the tube are closed by steel end caps 3 which are sealed around the side wall of the tube by O-rings (4, Fig. 2). Holders 5 for a fluorescent lamp (6) are secured within the tube at each end, and an electrical supply cable extends into the tube through an aperture 7 in the side wall. The tube may be masked by sheeting or painted with light-impermeable paint over most of its surface, only two strips 11, 12 being left clear along the length of the tube. A reflector (13, Fig. 4) is mounted within the tube. The fluorescent lamp (6) illuminates the reflector (13) which is directed to cast the light towards the translucent strips 11, 12 of the tube. The light is prevented from passing through the remainder of the tube by the masking paint or sheeting so only two beams of light emerge from the tube, through the strips 11, 12. The one-piece construction of the tube 1 prevents any rain penetrating through the side wall in the area of the lamp. <IMAGE>

Patent GB-2214737-A (GB)
Title: Subranging analog to digital converters
Inventor: BELL ALAN JOSEPH
IPC: H03M1/00
Filed: 1988-01-25
Abstract: A subranging analog to digital converter in which a first digital conversion of an input signal A is effected by a (e.g. 8-bit) flash analog to digital converter 18 to provide the most significant bits of the required (e.g. 12-bit) digital output 30. This first digital signal is converted back in a digital to analog converter 34 to provide an analog representation of just the most significant bits, which analog representation is subtracted from the input signal A before making a second digital conversion in the flash converter 18 (with increased gain provided by opening a switch SW1) to provide less significant bits of the digital output. The result of the digitising conversions are latched in respective latch circuits 24, 26. By combining the latched digital signals in a full adder 28 arranged to overlap some of the bits of the two latch circuits 24, 26, it is possible to effect the first conversion before the circuit, and in particular a track/hold amplifier 10, has fully settled, since an error in the first digital signal will be fed back and included as an error of the opposite polarity in the second digital signal, and addition of the two digital signals will cancel the error. <IMAGE>
