Title: Improvements in and relating to braking systems
IPC: B66D5/26
Filed: 1936-02-05
Abstract: 470,070. Brakes. BRITISH THOMSON-HOUSTON CO., Ltd., and PETCH, T. H. Feb. 5,1936, No. 3507. [Class 103 (i)] A brake for a winding engine &c. applied by a weight and released by fluid pressure, which may be released automatically, comprises a fluid transmission 5 between the weight 10 and the brake-applying lever 2 controlled by a valve 14 in order to vary the action of the weight. If the fluid transmission 5 fails the weight operates the lever 2 by means of collars 56 on the rods 11. The brake is released by fluid admitted beneath a piston 8 connected by the rods 11 to the weight 10 and to a piston 6 between which and a piston 4 connected to the brake lever 2 is the fluid transmission controlled by the valve 14. Release of fluid from beneath the piston 8 allows the weight 10 to fall which draws down the piston 6 and applies pressure to the fluid transmission and thus to the brake lever 2. The valve 14 may then be manipulated to reduce the pressure in the fluid transmission and relieve the braking pressure. This valve may only be operated in emergency by a solenoid 53 simultaneously with an automatic emergency valve 43. To prevent excess pressure in the fluid connection, a relief valve 57 is provided. Fluid released from the fluid connection passes into the reservoir 17 and returns through a non-return valve 54. Collars 55 raise the lever 2 and release the brake. Admission and release of fluid beneath the piston 8 is controlled by a valve 31 operated by a hand lever 23 and a follow-up piston 32, which mechanism gives a graduated application and release. This control takes place through pipes 49, 48, 13 provided with a valve 18 controlled by an inertia governor 21 in order to maintain a predetermined deceleration. This connection is also controlled by an emergency valve 43 adapted to be released by a solenoid 45 to produce emergency brake application.

Title: Improvements in or relating to the production of high speed steel powder and articles produced therefrom
IPC: B22F9/00
Filed: 1943-03-03
Abstract: A process for the production of high speed steel powder suitable for powder metallurgy which comprises preparing a ferrous alloy having a carbon content substantially in excess of that desired but being otherwise of the required composition, mechanically disintegrating the solid alloy to powder form and decarburizing the powder in the solid state to produce high speed steel of desired carbon content. The initial alloy may contain 1.5-3.0 per cent carbon and the decarburized alloy may contain 0.5-0.8 per cent carbon.  The initial alloy in a molten state may be subdivided by granulation before reduction to powder and the granulating step may be followed immediately by a heat treatment involving heating and quenching to enhance the brittleness of the material, for example heating to at least 1000 DEG C. and quenching in water or oil.  This treatment may be followed by heating at 580 DEG C-610 DEG C. and cooling normally without quenching. Specification 484,662 is referred to.

Title: Circuit arrangement for distortion supervision in teleprinter exchange systems
IPC: H04L12/26
Filed: 1938-02-04
Abstract: 498,373. Type-printing telegraphy. SIEMENS & HALSKE AKT.-GES. Feb. 4, 1938, No. 3578. Convention date, Feb. 16, 1937. [Class 40 (iii)] A device for testing distortion in a subscriber's transmitter is situated at the exchange and may be brought into operation at the will of the subscriber. By dialling a number appropriate to the testing device, a, subscriber T is connected through a relay A to distortion indicators V1-V4 responsive to various degrees of distortion. A signal is sent by him for test and those indicators whose appropriate values are exceeded pass current through the windings C1-F1 of relays C-F which close corresponding contacts c1-f1 to complete holding circuits through windings C11-F11 which then reverse contacts c2-f2. Following the test signal, the subscriber sends a '' Who are you ? " signal, to which code discs on a shaft NW are responsive, so closing contacts n1-n5 and, through relays R1-R5, completing the circuit r1-r5 of a releasing magnet AM2 which allows a shaft driven by a motor M2 to rotate. This shaft bears code discs S1-S4, each capable of sending a signal corresponding to its appropriate distortion indicator. Thus a signal, corresponding to the maximum distortion measured, is sent through one of the contacts SK1-SK4 to the subscriber's receiver. A further contact u interrupts the holding current of the relays C-F when the signal has been sent.

Title: Testing the adressing circuitry of a data store
IPC: H04L69/40
Filed: 1973-01-24
Abstract: 1365057 Testing data stores INTERNATIONAL BUSINESS MACHINES CORP 24 Jan 1973 [26 Feb 1972] 3608/73 Heading G4C The addressing circuits of an addressable data store are tested by sequentially addressing the storage locations, writing into each addressed location at least a part of its address, again sequentially addressing the storage locations, and comparing each applied address signal or part thereof with data read from that location, and generating an output AS only when the result of the comparison changes from match to mismatch or vice versa. As described, the output from the comparator is fed to a control circuit 5 which reverses the comparison criterion each time the comparator output changes to produce a signal AS which enables gate 6 thereby to record the current address at 4. The resulting recorded addresses delineate fields in the store in which the addresses do not match the stored data. Circuit 5, Fig. 2, includes two AND gates 57 and 55 enabled by a clock signal T1, the output of a latch 51 which stores the comparator output when clocked by T2 which follows T1, and the true and negated comparator outputs.

Abstract: 306,085. Liais, L. Feb. 15, 1928, [Convention date]. Void [Published under Sect.. 91 of the Acts]. Falling streams, commingling. - A method of manufacturing agglomerates of coal or other fuels consists in heating the powdered fuel to a temperature of from 125‹ C. to 145‹ C. and' regularly pouring this at a fixed rate in the form of a sheet from a height into a mixing apparatus and conveyer. Sheets or jets of pulverized or liquid pitch are similarly poured from a corresponding height and at a proportional rate of delivery in such a manner that the sheets of pitch meet and mix with the sheets of fuel at a certain distance above the common mixing and conveying apparatus, which apparatus completes the mixing and delivers the material to a press. The powdered fuel, heated to the given temperature, is supplied to a measuring device 1 of known type from which it is fed at a predetermined rate to a channel 2 which discharges it as a sheet 3 at a fixed height above an endless screw 4 arranged in a mixing and conveying trough 5, from which the compound is delivered to moulding presses. A second measuring device 6 and channel 7 arranged symmetrically opposite to the former device and channel supply a proportional amount of pulverized pitch in the form of a sheet 8 discharged at the same height above the screw 4 as the sheets 3 of fuel. The two sheets meet and mix at a zone 9 a certain distance above the screw 4. The mixture is completed by the screw, which with its trough has a certain temperature due to the circulation of hot fuel, and the homogeneous paste is delivered at the presses at a lower temperature of about 80‹ C. to 100‹ C. This reduction in temperature may, if necessary, be produced by the use of several screws or of cooling devices emploiyng air or water. The sheet of powdered pitch may be replaced by a jet of liquid or atomized pitch.

Title: Improvements in and relating to the production of cellulose
IPC: D21C9/02
Filed: 1938-02-10
Abstract: The process described in the parent Specification for treating vegetable raw materials with a saturated lime solution containing substantially no solid phase is associated with a subsequent washing process in which the digester material after running off the lime liquor is transferred to a hollander, preferably a combined grinding and washing hollander, or similarly acting appliance, and whilst being flushed with water, undergoes fibre separation therein until the washing water on standing deposits no or only a little sediment. The process is particularly suitable for the treatment of varieties of straw, grasses, or bamboo, or other materials which have a high content of silica.  The treatment with milk of lime results chiefly in the solution of pentosanes, and lignins.  The subsequent washing with separation of the fibres removes solid impurities in the form of a fine-grained mud.  The fibres are retained by the sieve of the hollander.  The washing treatment enables the total quantity of lime required for the refining treatment to be reduced.
