Patent GB-896413-A (GB)
Title: Improvements relating to serial adding circuits
Inventor: SYMONS MICHAEL
IPC: G06F7/38
Filed: 1957-08-21
Abstract: 896,413. Circuits employing bi-stable magnetic elements. ELECTRIC & MUSICAL INDUSTRIES Ltd. Aug. 21, 1958 [Aug. 21, 1957], No. 26338/57. Class 40 (9). [Also in Group XIX] A serial binary adder for inputs at A and B and providing a sum output at 31 (Fig. 1), comprises three magnetic cores 1, 2 and 3 acting as threshold 3, 1 and 2 gates respectively and each having three input windings energized by the A and B inputs and the carry signal on C, the output pulse from core 3 on resetting by a pulse at 20 being lengthened by the RC network 22b, 23b so that the " carry " collector current of transistor T3 will continue into the next denominational input at A and B. By arranging the effects of currents in windings 27 and 28 due to resetting of cores 2 and 3 to cancel out, so that core 25 is set after the end of the reset pulse through 29, 16, 17 and 18 if core 1, or core 2 only, was previously set, the correct sum output is read out of core 25 at the next re-set pulse. Fig. 3 shows a simplified arrangement in which the necessary cancellation of outputs from the gate cores 2 and 3 is effected by connection of the output windings 13, 14 and 15 in series with 14 and 15 in opposition, the sum output being obtained at 40 without the use of an intermediate core; the carry signal is derived from a second output winding 15a on core 3. The gating action of the cores is obtained by the use of appropriate windings, using the notation that a " 1 " winding provides a field just sufficient to set the core, a " ¢ " winding a field of half that strength, and a " - ¢ " winding a field of similar strength but in the reverse direction, then windings 4-9 are all " ¢ "; 19 is a "-¢" bias winding, and 10-12 are " 1 " windings (windings 16-18 and 29 are all capable of resetting their cores whatever the inputs). Specification 893,355 is referred to.

Patent GB-688983-A (GB)
Title: Improvements in the production of gases containing sulphur dioxide
IPC: C01B17/52
Filed: 1950-11-01
Abstract: Sulphur dioxide-containing gases are produced by roasting sulphide-containing ores e.g. iron or zinc sulphides, at say 800-1000 DEG C in one undivided layer of roasted material maintained in a random turbulent motion by the oxygen-containing gases necessary for roasting entering the layer from below, and by the roaster gases formed, wherein the ore is introduced into the layer with a preponderating grain size of 0.1-10 m/ms.  The pressure drop through the layer should be less than the hydrostatic head calculated from the bulk denslty in the quiescent state of the nearly completely roasted material of which the layer practically consists and from the height, e.g. less than 100 cms., of the layer in the quiescent state Roasted material may be withdrawn from the upper, middle, and lower parts of the layer to maintain the size distribution, and that withdrawn from the lower part may be subjected to a further roasting in a fluidized layer.  Specification 660,778 is referred to.

Title: A new or improved hydraulic coupling for power transmission
IPC: F16D31/04
Filed: 1938-09-13
Abstract: 519,039. Hydraulic couplings; variable-speed gearing. GREEN, J. A. Sept. 13, 1938, No. 26670. [Class 69 (ii)] [Also in Group XXIV] A hydraulic coupling is constructed with a number of gear pumps 14 mounted in an annular space 8 between casings 6, 7 the inner members of the pump gears being fitted with planet gears 16, Fig. 2, gearing with a sun-wheel 17 on the driven or driving-shaft 18 mounted in bearings in the casing 7 and in a casing 19 which contains the gears 16, 17 and is secured to the casings 6, 7 by bolts 39 which may also connect the whole coupling to a flange 40 on the driving or driven shaft 41. The pump chambers 9 are integral with the outer wall 11 of the annular member 8. Each pump 14 forces fluid into a separate chamber 130 from which the fluid passes through the parts 20a of a piston valve, or by means of another form of valve, through a passage 21 in the casing 7 to a chamber 13a. A pipe 31 connects the chamber 13a with the pump chamber 9, and a non-return valve controls the passage of fluid into the pipe 31 and so prevents reverse drive. The valves 20 are moved equally and simultaneously by rockers 26 operated by a slid:ng sleeve 25, and when fully open no power is transmitted. When the valve is closed or partly closed the resistance to rotation of the gears 16 causes power to be transmitted to the sun-wheel; The chamber 13b of one pump may be connected to the return pipes 31 of an adjacent pump, and other types of pump than the gear pumps shown may be employed. The bearings of the pump gears 14 in the casing 7 may be drained by pipes 38 leading to the inlet pipes 31.

Abstract: 602,525. Trailer brakes. ISHERWOOD, J. Oct. 16, 1945, No. 27002. [Class 103 (i)] In an automatic brake-operating mechanism for a trailer vehicle of the kind in which the brakes are normally applied, but are released in response to a pulling or pushing effort by the tractive vehicle, the brakes are normally applied through a cable 17 by a spring 21 but are released on application of a pushing or pulling effort to the draw-bar 7 by means of a lever 13 pivoted at 13e to the towing bar 5 and at 14 to a member connected to the cable 17, or by a lever 12 pivoted at 12e to the towing bar 5 and in mesh with lever 13 at 12b, 13b. On the draw-bar 7 are secured two collars 10a, 10b, which by engaging the forked-end 12a, 13a of the levers 12, 13 release the brakes when pushing and tractive efforts respectively are applied to the draw-bar, these efforts being transmitted to the towing bar 5 through springs 11b, 11a bearing on the draw-bar guides 6b, 6a respectively, and also by direct engagement of members 8 and 9, fixed to the draw-bar 7 with members 6a, 6b respectively.

Title: Improvements relating to tensioning devices for drive chains
IPC: F16H7/08
Filed: 1928-09-21
Abstract: 316,051. Morse, F. L. Sept. 21, 1928. Tension-arrangements.-In means for automatically maintaining a constant tension upon driving-chains, for example in automobile camshaft drives, a tensioning sprocket (not shown) is mounted to turn loosely on an eccentric, lever, or the like 9 which is loose on a fixed pin 10 and is secured to an eccentric 14 to which is secured a strap 24, the other end 23 of which is adjustably inserted in one of a series of slots 22 in a drum 21 connected to a fixed pin 16 by a spiral or other spring 13. The pin 16 is carried on an arm 17 adjustably clamped upon the pin 10. The throw of the eccentrics is so arranged that change in the leverage of the eccentric 9, as the driving- chain stretches, and change in the pull of the spring 13 upon the strap 24 are compensated for by change in the leverage of the strap 24 about the pin 10, the eccentric 14 being, if necessary, made cam-shaped for this purpose. A pawl 26 and a ratchet-wheel 25 rigid with the eccentrics 9, 14 and concentric with the pin 10 are provided to maintain the tension. In a modification, the drum 21 may be arranged eccentrically to the pin 16 and the eccentric 14 despensed with. The sprocket-wheel may replace one of the existing sprocket-wheels in an automobile front drive, in which case a coupling would be introduced between the wheel and its shaft to permit the necessary movement of the wheel.

These contacts correspond in number and position to the number and geometrical projection of the oscillator positions on the plane of transmission or reception. One end of the retardation line is connected to the generator or indicator 7 and the other end is closed by a resistance 8. In a modification, the carrier 9 is fixed and the contact surface made rotatable.

The term " lid covers any analogous fitting, such as a cap or capsule, provided with a rim. With the construction shown in Fig. 3, t.he body portion need not be resilient or alternatively, a rigid lid may be employed provided the rim-depressions of the body-part are of sufficient size. An arrow on the body indicates where pressure is to beapplied to effect the opening, but with a resilient body part pressure could be applied to the rib 9 in a direction perpendicular to that indicated. The containers are preferably of elliptical shape but are not necessarily so, and may also be polygonal or rectangular with the indentations &c. formed at diagonally-opposite corners.
