Abstract: 1501492 Fluid distributor beds NATIONAL RESEARCH DEVELOPMENT CORP 2 Aug 1976 [2 May 19751 18470/75 Heading B1F [Also in Division C7] Fluid distribution to a particulate electrode (fluidised, static or otherwise) is effected by means of a predistributor which feeds the main distributor and constrains the fluid to change direction by at least 180‹. The two distribution zones are separated in such a way that their interconnection does not alter the fluid flow produced by the predistributor before it reaches the main distributor. In Fig. 1, a blind - ended tube 2 has a slit 4 which feeds liquid from passage 6 into annular space 7 in a block 8. This predistribution arrangement supplies the main distributor comprising ballotini in space 10 bounded by gauze 12. The electrode is in space 13. Other objects such as rods or Raschig rings may take the place of the ballotini. Alternative shapes for space 10 are disclosed. The objects of the main distributor may be inert or chemically reactive.

Title: Facsimile method
IPC: H04N1/409
Filed: 1962-05-15
Abstract: 986,534. Copying by scanning. TIME Inc. May 15, 1962 [May 16, 1961], No. 18669/62 Heading H4F. The invention relates to a modification of the facsimile apparatus described in Specification 986,531 in which, instead of employing a single photo-electric cell to view the auxiliary scanning area concentric with and larger than the main scanning area, there is provided a plurality of small photo-electric cells 401 which may comprise, for example photo-transistors, and which are arranged with a central cell and other cells arranged in rings and sectors. The arrangement permits the measurement of density of small details in the auxiliary area and the control of the signal from the main scanning area, so as to increase local contrast, as a function of both the average density of the auxiliary area and the maximum contrast between the small details. For this purpose a first circuit comprising resistor network 403 and D.C. amplifier 404 adds the signals from all the photo-electric cells 401 to provide a signal on lead 405 representative of the average tone density of the area, whilst maximum and minimum signal selector networks 410 and 420 select the signals from the cells which represent respectively the maximum and minimum density. The minimum signal is reversed in phase in amplifier 430 and then applied together with the maximum signal to a summing circuit to derive at point 415 a signal proportional to the difference of the signals and representative of the maximum contrast in the area. The average density signal on lead 405 is applied to a first triode 45, in a weighting circuit 448 and the " maximum contrast " signal from point 415, together with the " least ink " "black" signal obtained over lead 71, are applied to the second triode 449. The signal to control the main area scanning signal, so as to produce increased local contrast, is derived from the common cathode load 454 and is applied over lead 31 to control the under-colour modulators in the respective colour channels. The signal is also applied to modify the " black "  " signal " in a circuit 270. The " black " signal and the " average density " signal, before application to triodes 449 and 451, are first converted to alternating signals by choppers 440, 441. The alternating output from the cathode load 454 is rectified at 461. The " maximum contrast " signal from point 415 is a D.C. signal and when applied to triode 449 functions to vary the gain of the stage for the " black " signal. In practice, more photo-electric cells than those shown are used. The cells may be decreased in sensitivity with displacement from the centre of the area to compensate for the increase in cell area. Alternatively, the number of cells per ring may be increased as the rings get radially larger. Specifications 765,443, 765,444, 794,201, 827,865, 986,532 and 986,533 also are referred to.

Filed: 1975-05-05
Abstract: 1490777 Brake actuators ROBERT BOSCH GmbH 5 May 1975 [19 June 1974] 18696/75 Heading F2F A brake actuator comprises a spring loaded cylinder 6 connected at 7 to brake actuating linkage 8, 9 and a valve member 19 for selectively connecting the cylinder to a hydraulic pressure source 26 or a discharge line 32. In the event of failure of source 26 after the brake has been applied, valve member 19 may be reciprocated by repeated operation of lever or pedal 37 to pump fluid from chamber 31 to cylinder 6 to release the brake. The spring 4 loads cylinder 6 in the brake applying sense and brake release is effected by moving the lever or pedal 37 so that valve 19 admits fluid to the cylinder from source 26 via passage 14 in fixed piston 10. When the pressure is sufficiently high valve 19 moves downwardly until one of its control edges 23 cuts off passage 14. Brake application is effected by spring 4 when lever 37 is moved in the opposite sense so that cylinder 6 exhausts via passage 15, the interior 29 of valve 19 and chamber 31. A check valve 28 ensures that failure of source 26 does not cause immediate brake application.

Abstract: 262,839. Western Electric Co., Ltd., (Bell Telephone Laboratories, Inc.). July 25, 1925. Phonographic recorders and reproducers.- Comprises means for rendering telephone instruments and phonographic recorders and reproducers uniform in their action over a wide range of frequencies. For this purpose the instrument is associated with a transmission line for absorbing mechanical vibrations, analogous to an electric line and comprising an elongated solid body of homogeneous vibration-dissipating material. In the embodiment shown a rubber tube or cylinder 36 is attached at one end to the input mechanism, such as a gramophone tool-arm 20, the other end being idle. The cylinder 36 may be of pure gum rubber, 9" long and ¢" in external diameter, or it may be of leather, felt, cork, or spongy lead. It may be of uniform section or tapered, and may be supported by a felt, cotton or spongy rubber ring at its idle end : or it may be supported throughout its length by a wrapping of cotton, felt, or the like resting upon a surrounding casing, or by an aluminium or like strip 35, Fig. 8, lying in a bore which is formed in the tube and filled if desired with loading material 36a such as lead shot. The magnitude of the cylinder 36 is so calculated that energy reflected from the idle end shall be dissipated before returning to the input end. The cylinder is shielded by a casing formed of angle irons 43, 45, which is universally pivoted to its mounting at the idle end. Attachment of filter to tool arm and armature.

Abstract: 573,710. Gyroscopic apparatus. BENDIX AVIATION CORPORATION. Nov. 15, 1943, No. 19035. Convention date, Nov. 13, 1942. [Class 97 (iii)] In caging a universallymounted gyro-vertical a rotatable torque-exerting member normally coaxial with the spin axis is brought into engagement with an element projecting from the rotor casing to cause the rotor to precess to a normally central position. As shown in Fig. 3, the gimbal-supported casing 10 of the gyro rotor has a downwardly-directed caging pin 18 which may be engaged by a finger 32 when this is raised to the position shown in full lines and is given a rotary movement, by pushing-in and rotating a knob 34. The pressure of the finger on the caging pin 18 causes the gyro to precess and the pin to slide down the finger into a central position where it is retained by a spring catch 27, Fig. 5. A helical spring acting as a clutch ensures rotation of the knob 34 and finger 32 in one direction only. In a modification, Fig. 6, the finger 130 for engaging the caging pin is turned and raised simultaneously by rotation only of the operating knob 122, these movements being effected through worm-and-cam mechanism 124, 143. A cam-operated pin 148 is protruded through the bottom of the casing to inform the operator that the caging mechanism is in operation. In a modification wherein the caging apparatus is operated under remote control, the knob 122 is dispensed with and the worm-andcam mechanism 124, 143 is rotated by a flexible cable actuated by a distant crank handle. An indicating disc geared to the crank handle informs the operator when the gyro is caged or uncaged. The remote control may be effected by an electric motor instead of by a crank handle, in which case the motor is started up (in order to drive the flexible cable and caging mechanism) by throwing over a switch, and is stopped at the end of the caging or uncaging operation by the action of a switch-opening cam driven by the motor.
