Patent GB-1245137-A (GB)
Title: Improved servo valve
Inventor: WALTERS RONALD BERNARD
IPC: F15B13/043
Filed: 1968-12-24
Abstract: 1,245,137. Fluid-pressure servomotor systems. SPERRY RAND Ltd. Dec.18, 1969 [Dec.24, 1968], No.61263/68. Heading G3P. An electro-hydraulic servovalve in which the movement of a flow controlling element 30 is effected indirectly through the movement of a spring-loaded flapper 32, is characterized in that the flapper 32 is carried and moves internally within the flow control element 30. Fluid flows from an inlet 48 to diverging orifices 44, chambers 40, 42 and, with the valve in the position shown, through both flappers, nozzles 36, 38, passages 54 and exhausts 56. Upon actuation of the electric motor 20 the armature 18 moves to the left or right according to the current direction and in so doing moves the valve members 32a of the pilot valves. Due to the unequal fluid-pressures in chambers 40, 42 the spool 30 moves and so opens one of the outlets 58.
Patent GB-782937-A (GB)
IPC: H02K17/30
Abstract: 782,937. Control of A.C. motors. STANDARD DAYTON CORPORATION. March 31, 1955 [April 5, 1954], No. 9397/55. Class 38 (3). [Also in Group XXXV] The squirrel-cage rotor of a braked induction motor has grouped conductors (see Group XXXV) to lock it at rest when energized for braking. The motor has a direct-on-line, single or polyphase, running winding 20, and braking windings 22, 24 of higher pole-number equal to the number of groups of rotor conductors. Winding 22 is shorted and winding 24 is energized when the running winding is de-energized. A normally-open timer relay 38 delays the deenergization of the braking winding 24 on deenergization of the running winding by the main relay 30, for a sufficient period to stop the motor. In a modification, the shorted winding 22 is provided with tapping points between which a voltage is induced by the main winding to pickup, and by the braking winding to hold in, a relay which disconnects the braking winding when the machine is at rest.

Title: Feeding material onto building elements
IPC: B29C44/36
Filed: 1978-07-14
Abstract: A building element comprising a board component having transverse stiffening bars is filled between the bars with a filling material e.g. polyurethane foam from an applicator head. The building element is moved at a uniform speed in a direction perpendicular to the bars and the applicator head moved at a similar uniform speed in the same direction above the moving building element, and also executes a reciprocating motion above the moving element and parallel to the bars, while at the end of each traverse moving back rapidly in the opposite direction to the building element, whereby successive and contiguous lines of filler material are deposited on the board component between adjacent stiffening bars. The invention also provides apparatus for carrying out the process, wherein for example a building element is moved on a rolling conveyor. The process and apparatus may be controlled by automatic control means.

Patent GB-2014395-A (GB)
Title: Infra-red imager
IPC: H04N5/33
Filed: 1979-01-31
Abstract: The imager comprises an array 4 of detectors, and an array 6 of LEDs, each detector being connected to a corresponding LED by a respective signal processing channel 5. Common to all the channels is a ramp generator 12. Each channel has a comparator 9 which compares the ramp with the signal from its detector to produce a pulse width modulated signal for its LED. Thus the LED is always driven at the same point on its characteristic, variation of brightness being achieved by variation of pulse width. Use of a common ramp generator makes for simple change of ramp shape, temperature window, offset, and ??? law by changing only the ramp generator. <IMAGE>

Title: Method for remote determination of the geological nature of a homogeneous surface
IPC: G01V8/02
Filed: 1979-10-17
Abstract: An optical method for remote sensing of the homogeneity of, and identification of an immobile target surface is disclosed. Light reflected from the surface of target 12/14 is electro-optically detected by polarimeter 10. The Stokes parameters of the detected light are measured in four specified preselected, adjacent, spectral wave bands. A discrete value termed the polarization intensity index is calculated from calculations of polarization indexes using the measured Stokes parameters. Each homogeneous surface has a characteristic polarization intensity index value. Substantially identical surfaces display substantially identical polarization intensity index values. By comparing the polarisation intensity index values of unidentified target surfaces with a set of previously determined polarization intensity index values for different, known target surfaces, the geological nature of an unidentified target surface may be determined. <IMAGE>

Title: Connecting wiper arm to wiper blade assembly
IPC: B60S1/40
Filed: 1979-11-02
Abstract: A wiper arm (21) having a free U-shaped bent end is pivotally secured to a wiper blade assembly by a resilient clip (22) which is articulated to a pivot pin spanning the sides of a yoke of the wiper blade assembly. The limbs 28, 30 of the clip abut against the mutually facing, substantially parallel surfaces of the bent free end of the wiper arm. Although the width 70 between portions 60 of the clip is greater than the width 66 which is equivalent to the width between the sides of the yoke of wiper blade assembly, it is possible to insert the clip between the sides of the yoke because of its resilience. This avoids lateral play between clip and yoke. <IMAGE>

Title: Electronic equipment practice
IPC: H05K7/20
Filed: 1979-11-06
Abstract: An electronic equipment practice, e.g. for data processing or telecommunication systems, is based on a vertical wall-like member (1) which may have flanges along its vertical edges. On the front of this member there are individual rectangular equipment units (3) of modular type, mounted with narrow gaps between them, which gaps can be used for wiring access. The whole is enclosed by a front cover (4), and if free-standing, by a back cover (9).
