Title: Improvements in or relating to the manufacture of coal or like briquettes
IPC: C10L5/16
Filed: 1920-07-10
Abstract: 170,092. Lloyd, H. G. July 10, 1920. Making bricks.-The binding agent such as bitumen, asphalt, pitch &c. is melted and just sufficient water or wet steam is added to cause the binder to froth whereupon the powdered stone, gravel, sand, &c. to be briquetted which may include lumps, is added. The binder should be sufficiently pure to be soluble in carbon bisulphide at 77‹ F. The temperature of the binder should be above the flowing point but should not exceed the cracking point and it should preferably be maintained considerably above the boiling point of water while the water is added until the desired amount of frothing has been obtained. The water may be mixed with the material and the two added, for example in the form of a jet, to the molten binder. The proportion by weight of water to bitumen may vary beween 4 to 15 per cent and 4 to 12 parts of bitumen may be employed with 96 to 88 parts of stone &c.

Title: Improvements in and relating to travelling cranes
IPC: B66C7/00
Filed: 1920-07-12
Abstract: 152,312. Deutsche Maschinenfabrik Akt.-Ges. March 15, 1918, [Convention date]. Overhead travellers.-Interchangeable guiding- frames for the load are fitted detachably to the traveller of a travelling crane so that the crane can be used for a variety of purposes. Fig. 3 shows one construction in which one guiding- frame c, fitted with hoops i for engaging pigs of metal, is suspended from the traveller, while a second frame, carrying a balance bar d for charging a furnace, is suspended over a wall bracket g in such a position that the traveller can run under it and lift it from the support. Alternatively, both guiding-frames can be run on to wall brackets and the traveller used with a crab or the like to manipulate loads in the usual manner. In a modified construction, the support for the guiding-frame, when not in use, is fixed to one end of the crane bridge. In this latter case, if the pilot's cabin is carried on the guiding-frame, the crab can be controlled from the cabin even when the frame is on the support. For this purpose the main electric leads run the whole length of the travelling bridge of the crane, and the controller in the cabin contacts with the leads by means of trolley-wheels or collectors, thus ensuring contact therewith in all positions of the frame.

Title: Improvements in or relating to Methods of and Apparatus for Recording and Reproducing D.C. or Low Frequency Signals
Inventor: FREEMAN JOHN ANDREW EASTCOURT
IPC: G11B5/027
Filed: 1966-05-12
Abstract: 1,188,503. Recording methods. MARCONI CO. Ltd. 2 May, 1967 [12 May, 1966], No. 21205/66. Heading G5R. A method of making a record from D.C. or low-frequency A.C. signals comprises the steps of transforming them into width-modulated pulses, differentiating the pulses, and recording the differentiated resultant. Preferably a method of recovering the signals utilizes them to control the state of a bi-stable circuit or device to provide width-modulated pulses, and detecting the modulation. Recording.-The D.C. or low frequency (e.g. up to several hundred cycles per second) A.C. signal is applied at 10 to a pulse width modulation circuit P to the output of which is coupled a differentiator D which feeds a recording head H past which travels magnetic tape T, Fig. 1a. Playback.-The output of a reading head H, Fig. 1b adjacent tape T, is fed into a bi-stable circuit B which in turn feeds into a detector I, the output of which appears at the terminals 11. Pulse-width-modulation circuit, Fig. 2.-The input is applied between terminal 5 connected to an emitter follower transistor T5 and earth terminal 7. The differential amplifier is formed by two transistors T3 and T4 connected as a longtailed pair with a common emitter resistor R2. The multivibrator circuit is formed by the transistor pairs T1<SP>1</SP>, T1<SP>11</SP> and T2<SP>1</SP>, T2<SP>11</SP>, diodes D3 and D4, timing capacitors C1 and C2 and resistors R1 and R3. Two transistor pairs T6 T8 and T7, T9 constitute a power amplifying arrangement feeding the output terminals 8. In a modification of the part of Fig. 2 indicated by the dashed line, (Fig. 3, not shown), a circuit is obtained which can be used in the reproduction arrangement of Fig. 1b. Thus when the recording and reproducing arrangements are combined in a single unit the circuitry of the pulse width modulation arrangement can be modified simply by suitable switching in and out of appropriate components to provide a bi-stable circuit for use in recovery of D.C. signals.

Abstract: 982,091. Photo-electric control systems. AMF INTERNATIONAL Ltd. June 15, 1961 [June 17, 1960], No. 21381/60. Heading G1A. The force exerted on a pan V at one end of an arm A is opposed by the torque due to a current in the coil D of a galvonometer movement, the current being measured as an indication of the force and being supplied by a bridge circuit containing two phototransistors G, H, whose illumination from a source L and lens M is varied by a wedge shaped shutter or aperture B at the other end of the arm A. The controlling torque exerted by the spring E of the galvonometer movement may be set by a calibrated knob F so that variations of force from the set value may be measured. The phototransistors are mounted together in a block which may be moved either with or without the source L in the direction of the axis of symmetry of the wedge shape of the aperture or shutter to control their sensitivity. The meter indicating the current through the coil D may have a variable shunt to control its sensitivity and it may be incorporated in an R-C circuit to reduce instability in the system. The device may be used for weighing single articles, for measuring in terms of force, the velocity of a fluid or stream of particles directed on to a vane in place of the pan V, or (by means of a current integrating meter) to measure the average weight of series of articles. Alternatively the signal may be fed to a pulse height analyser or "kick sorter" of known type to grade articles according to weight.

Title: Hammer mechanism for the printing devices of calculating machines
IPC: G06C11/04
Filed: 1922-08-09
Abstract: 208,190. Vidal, A. E., (Optische Anstalt C. P. Goerz Akt.-Ges.). Aug. 9, 1922. Adding and subtracting apparatus; clear signals and marks; printing totals. - Relates to machines having totalizing-counters capable of being raised and lowered, with means for setting the hammer mechanism of the clear signal during the printing of a total and means for printing the clear-signal with the first item of a new calculation, and comprises means for connecting the hammer-tripping lever of the clear signal to the hammer-tripping lever of the units denomination through a coupling which is disconnected during item and sub-total printing, but during total printing is set by levers operated both from the main crank and through the lifting movement of the totalizer. The printing hammers for the digits are tripped by a bail 59 engaging notches in spring-urged levers 85 when the latter are freed by the type bars. For printing zeros auxiliary levers 117 mounted on the levers 85 come into the path of pins carried by the lever 85 of the next denomination. The hammer 51 for the clear signal has a spring-urged tripping lever 54 and a lever 85 carrying an auxiliary lever 117 which can be turned about a pin 86 and held in its adjusted position by friction. Co-operating with lever 117 are a rod 75, carrying a pin 127, raised and lowered at each operation of the main crank, and a guide lever 130 which is raised and lowered through levers 132, 133 each time the totalizer is correspondingly moved. The guide lever 130 is urged by a spring 125 and carries a gravity-positioned toe-piece 138 and is loosely mounted on a pin 123 carrying a lever 126, Fig. 4. A pin 128 on the lever 126 engages a guide-slot in the guide-lever. During the printing of items and sub-totals the totalizer is raised during the last quarter of the return movement of the crank, i.e. when the pin 127 has been raised clear of the lever 126. In this case the guide holds the toe 138 out of the path of the lever 17 and the toe is raised idly. During a total-printing the totalizer is raised during the first quarter of thereturn movement of the crank. The pin 127 in this case is low enough to strike the lever 126 which through its pin 128 swings the guide and its toe 138 under the lever 117. When the guide is raised with the totalizer the coupling lever 117 is raised into the path of a pin of the units lever 85. During the next itemprinting this pin releases the hammer of the clear signal. The lever 117 is restored to its original position by the heel.
