Title: Process and apparatus for briquetting fine grained ores
Inventor: EISENHUT FRANZ
IPC: C22B1/24
Filed: 1954-03-03
Abstract: 757,118. Briquetting ores. GELSENKIRCHENER BERGWERKS-AKT.-GES. March 3, 1954, No. 6278/54. Class 82(1). In a process for briquetting fine-grained ores, the ore is mixed with solid fuel, calcic material e.g. lime, calcium hydrate or limestone, water and a binding agent consisting chiefly of pitch, in a device which also breaks up lumps of the mixture which exceed a certain size. The pitch may be natural pitch or that obtained from pit coal, lignite or petroleum particularly re distillates and residues from hydrogenation, distillation and cracking processes. The pitch preferably contains substances which volatilise at a temperature below the melting point of the material produced in smelting the briquettes, and if these substances are absent additions of, for example, naphthalene, anthracene and phenanthrene may be made to the pitch. In an apparatus for carrying out the process, ore, coal, lime and limestone from bunkers 1 . . 6 is fed by a conveyer 8 to a premixer 10 where water, about 6-12 per cent of the dry mixture, and pre-heated binding agent, about 3-8 per cent of the dry mixture are added at 16 and 17b respectively. The material from the premixer passes through a mill 11, having contra-rotating plates with projections to break up the lumps, and into a compressor 12 where the material is kneaded and forced through a perforated plate 12a. The strings of material are cut into short lengths by a rotary knife 12b and the lengths are formed into briquettes in a rotary drum 13, which are fed into a roasting furnace 15. The roasted briquettes are then screened at 19 and undersize material and residue fed back to the conveyer 8 by a conveyer 21. In modifications of the apparatus : (a) the premixer 10 may be omitted ; (b) the water and binding agent may be added anywhere but at the latest in the mill 11 e.g. by adding the water with the ore from one of the bunkers 1-3 ; (c) the rotary drum may be replaced by a rotary plate; (d) a briquetting press may be used instead of the devices 12-13.

Title: Improvements in or relating to electrical signalling systems
Inventor: HART RONALD IAN
IPC: H04J3/06
Filed: 1961-02-23
Abstract: 964,710. Multiple pulse signalling. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Feb. 16, 1962 [Feb. 23, 1961], No. 6706/61. Heading H4L. In an arrangement for interconnecting two time division multiplex pulse systems controlled by respective timing signals which are independent but nominally of the same frequency, and subject to long term drift, wherein to facilitate the connection of channels of the first system to channels of the second system in a different time sequence the signals are stored at the interconnecting point, when the phase relationship between the interconnected channels reaches a point such that the storage time approaches zero, automatic control equipment introduces a temporary change in the storage period. Fig. 1 shows an arrangement for interconnecting systems A and B in which each system provides twenty-five channels, each channel involving eight digits, and channel twenty-five being the synchronizing channel. The A system is controlled by digit clock DA controlled by pulses derived from the incoming signal and producing pulses DA1 to DA8 corresponding to the digits for a channel and by channel clock CA driven by clock DA and producing pulses CA0 to CA24, in which CA0 relates to the synchronizing channel. Phasesynchronizing circuits may be included. Similarly, system B is controlled by digit clock DB and channel clock CB. The incoming pulse cede modulation signals from A are fed via a regenerative repeater RRR to gates G1, G2, controlled by pulses from a toggle T1 so that when one gate is open the other is closed. The gate G1 is connected through a three-bit delay D1 to the gates CA1 to CA24 controlled by the channel timing pulses, and the gate G2 is connected direct to the gates CA1 to CA24, and thus pulse signals are passed to the stores S. No store is provided for the synchronizing channel since synchronizing signals now are provided by the system B. A store S, Fig. 2, comprises capacitors C1 to C8 supplied via gates GDA controlled by digit timing pulses DA1 to DA8. The stored information is read out via digit gates GDB controlled by digit clock DB and gate channel gate GCB controlled by channel clock CB. The gates, GCB are operable in a variable sequence to provide the required cross-connection of channels. Any two interconnected A and B channels will drift slowly in and out of phase with the drift of their respective timing signals and to ensure adequate storage time to avoid loss of signals it is necessary to prevent them from going into phase as by the introduction of 3-digit delay D1 each time the in-phase condition is approached, the DA clock being altered correspondingly. The required switching may be carried out by comparing the synchronizing channel C0 digit positions of system A with those of any channel in the B system to operate toggle T1 through appropriate gate circuits, Fig. 6 (not shown). Specification 960,388 is referred to.

Title: Process for the stabilisation of keratin solutions obtained by treating keratin-containing material with aqueous solutions of alkali metal sulphides
IPC: C09H1/04
Filed: 1946-03-04
Abstract: Keratin alkali metal sulphide solutions are stabilised by adjusting the pH to a value between 10.8 and 11.5 (measured by the glass electrode) such that the viscosity remains practically constant.  The pH may be adjusted by adding acid or acid-forming material, e.g. carbon dioxide, hydrogen sulphide, hydrogen chloride, and acetyl chloride.  An example describes the adjustment of the pH of samples of a sodium sulphide solution of hair to varying values, and refers to the results on viscosity. The viscosity may be raised by addition of methanal.

Abstract: 1371248 Non-metallic springs J H FENNER & CO Ltd 15 Feb 1973 [16 Feb 1972] 7057/72 Heading F2S A resilient mounting for a vehicle engine comprises U-shaped members 10, 12 with a limb 22 or 21 lying between the limbs 21, 23 or 20, 22 of the other, at least the outer pairs of the sides of the limbs 20, 21 and 22, 23 facing one another being connected by elastomeric elements 14 and 18; the two outer limbs 20, 23 are connectible respectively to the engine or the vehicle (with the limbs 20-23 at a slight angle to the vertical) and the two inner limbs 21, 22 have free end portions 24, 25 at a distance from further elastomeric elements 28, 30 in the bases of the U-shaped members but intended to abut and compress these elements upon abnormal movement of the engine, e.g. due to rough ground. The weight of the engine subjects only the elements 14, 16 and 18 to stresses, mainly shear stresses and relatively low stiffness characteristics accommodate normal engine vibrations before the elements 28, 30 are employed. The transition to higher stiffness is gradual because of the 0-45 degrees angle of the end portions 24, 25 to the U-bases. Instead of the end portions being angled, the surfaces of elements 28, 30 may be sloped. The elements 14, 18 may be of rectangular, instead of the shown parallelogram-shape in section; To combat torque-reaction forces, the mountings on the two sides of the engine are oppositely disposed. Instead of pairs of ears 32, each U- member 10, 12 may have a threaded stud and locating lug secured to it. The combined transverse dimension of the end portions 24, 25 may be greater than the transverse spacing between the limbs 21 and 23 or 20 and 22 so that the U-members are interlocked and support the engine even if the elastomeric elements fail.  In a further embodiment, instead of the single central element 16, there are separate elements (34, 36) each bonded to one of the limbs 21 or 22.
