Title: Improvements in machines for dressing fish
IPC: A22C25/08
Filed: 1938-04-01
Abstract: 513,174. Dressing fish. BAADER, R. April 1, 1938, No. 10062. [Class 28 (ii)] The guides 210, 211 of the machine described in the Specification 454,495, which are associated with the filleting knives 125-128, are replaced by guides, one for each side of the fish, each consisting of two main parts, viz., a part 23 or 31 having a narrow V-mouth which engages with the narrow part of the fish, and a part 22 or 30 having a wider V-mouth for engaging the wider part of the fish. The narrow and wide V-guides are connected together in such a manner that, as the narrow guide reaches the wider part of the fish, it is moved relatively to the wide guide which then engages the fish. The guide members are mounted on levers 206, 212 which are swung apart to allow the passage of the tail clamp 100 as described in the prior Specification. The guide part 22 consists of a pair of plates rigid with the lever 206 and the part 23 consists of two plates carried by bars 24 pivoted at 25 to the lever. A spring 27 tends always to swing the guide part 23 clockwise with respect to the part 22, so that when the guides start to close the forward part of the guide part 23 contacts with the fish before the clamp 100 has completely cleared the guides. The part 23 contains a third guide comprising two thin sheet-metal parallel plates 29 spaced just sufficiently ,to permit the passage of the fins of the fish. When the forward end of the part 23 first engages the fish, the plates 29 engage the fin at the end nearer the tail and straighten it for presentation to the knives. After the passage of the tail clamp, the levers 206, 212 have closed and the part 23 is brought to bear for its whole length on the fish, and, as the section of the fish increases, is pushed towards the lever 206 to allow the part 22 to take over the guiding. The ends of the plates 29 project between the knives 127, 128. The guide parts of the outer guide, associated with the lever 212, resemble those above described. The wide guide 30, however, is narrower than the guide 22, and is designed as in the prior Specification to enter the belly cavity of the fish under the control of the measuring lever 145. The belly fins are straightened and guided by plates 36. '

Title: Improvements in and relating to a method of processing lateritic nickeliferous ores
IPC: C22B23/00
Filed: 1959-03-24
Abstract: Lateritic nickeliferous ore is processed by (1) pulping it with the pH adjusted to more than 7 to separate about 80% of the Co and Cr values, (2) adjusting the pH to less than 7 to separate the Fe and Ni values from the remaining liquor as a concentrate, (3) smelting the Fe-Ni concentrate to a Fe-Ni alloy and a slag, (4) smelting the slag to produce a crude steel containing less than 1% Cr and (5) refining the crude steel to a commercial steel substantially free of Cr.  The Co and Cr values are separated from the alkaline pulp by gravity dressing, jigging, &c.  The Fe-Ni concentrate is smelted in an electric furnace lined with a paste containing Fe-Ni concentrate mixed with reducing agent.  After drying during the smelting operation, this lining is used as the ore-melting stock for the succeeding operation.  Similarly, the electric furnace used for smelting the slag is lined with a mixture of slag, coke breeze and flux.  The crude steel is refined in an electric furnace with oxygen injection and the addition of quicklime to decrease the Cr content.

IPC: C01C1/04
Filed: 1921-04-06
Abstract: 161,195. L'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. April 7, 1920, [Convention date]. Ammonia, catalytic production of from nitrogen and hydrogen; catalytic apparatus.-In the synthesis of ammonia under conditions of hyperpressure, the development of stresses in the wall of the pressure tube due to the differences in temperature between the inside and outside layers of the wall is minimized by heat-insulating the exterior of the wall, thereby maintaining a substantially uniform temperature throughout the thickness of metal. Any loss of heat which does take place may be compensated for by the provision of a variable electric resistance coil embedded in the heat-insulating material. The reaction tube T containing the catalyzing material C is also heat-insulated by means of material E, which may, for example, be asbestos, enamel, or a.vitreous coating of boric acid wound round with asbestos cord, or alternatively, the tube T may be made of refractory material which is a bad conductor of heat. The gases, which enter the apparatus at A, then circulate round the reaction tube and are heated at the expense of the reaction taking place therein. Since the wall of the pressure tube is not used for conducting away the reaction heat, this heat is removed in other ways, e.g. by the progressive admixture of cold gas with the gases supplied by the heat exchanger. Specifications 130,086, 130,087, 150,744, 155,302, 158,593, and 160,811 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) states also that uniformity of temperature in the walls of the pressure tube may also be secured by making the inner layer of the tube of viscous metal, the outer layers being either non-viscous, or strengthened by metal bands or the like of non-viscous metal. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to ultra-high frequency electrical transmission systems
IPC: H01P5/18
Filed: 1946-04-03
Abstract: 628,547. High-frequency electric transmission lines. PHILCO CORPORATION. April 3, 1946, No. 10274. Convention date, Oct. 31, 1944. [Class 40 (viii)] [Also in Group XL (c)] A unidirectional wide - band coupling between two transmission systems, for example wave-guides, comprises a plurality of couplers for coupling the transmission systems, the couplers being spaced apart an odd number of quarter wavelengths, the amount of coupling at successive couplers being proportional to the successive coefficients of the binomial expansion of (a+b)<n>, where n is one less than the number of the coupling elements. Fig. 2 shows the simplest form in which a main waveguide 35 is coupled to an auxiliary guide 36 through equal holes 31, 32 placed one quarter wavelength apart. Energy from the main guide radiates through both holes and propagates in both directions. Thus energy from left to right in the main guide will be in phase from left to right in the auxiliary guide, but will cancel out from right to left in the auxiliary guide. Thus a matched termination 37 including a measuring device such as a bolometer will measure energy due to energy flow from left to right in the main guide, while a similar instrument at 38 will read zero. In the same way energy from right to left in the main guide 35 will be measured at 38 and not at 37. This enables the relative strengths of an incident and a reflected wave to be measured when guide 35 is feeding energy to a load. The band-width of the arrangement is increased by providing two pairs of holes 31, 32 and 33, 34, Fig. 3, the pairs being an odd number of quarter wavelengths apart. Further improvement results if the holes 32, 33 coalesce to give the arrangement of Fig. 1. Holes 23, 27, 26 are a quarter wavelength apart, and hole 27 is made to have twice the coupling effect of holes 23, 26. By extending the principle any number of holes may be used, the sizes of the holes being proportional to the coefficients of the binomial expansion. Thus in a four-hole system the holes are in the proportion 1-3-3-1 and so on. The invention is stated to be applicable to coaxial lines and two-wire transmission lines. The couplings may be loops or probes, and phasing may be introduced by means of delay networks.

If a group selector is held unnecessarily, as by a calling subscriber omitting to dial, a maintenance officer or test clerk observing the individual fault lamp is enabled to trace the calling line by inserting a plug P into the test jack J of the engaged selector, thereby maintaining holding earth on the caller's P-wire which is now disconnected from the selector P-wire, and throwing a key KST which operates relays EA, ST. Relay EA prepares circuits for test relays PA, ... , PD while relay ST applies a positive potential to the caller's P-wire via the plug P and jack J and connects relay F to " flicker earth " contacts on the ringing- machine. Relay F interacts with slow-operating relay FF to step an identification finder comprising a switch A and other similar uniselectors. Rectifiers prevent the operation of test relays PA, ... , PD until the switch A encounters the positive potential on the caller's P-wire. A test relay, say PA, then operates to stop the switches and light two lamps, one indicating which switch has found the marked line and the other showing the position of the wipers, so that the combination of the lamps identifies the calling line. The equipment is released by removing plug P from jack J and restoring key KST to normal. If either one of plug P and key KST is left operated without the other, an alarm bell B is rung over the auxiliary springs of the test jacks of the selectors.

Patent GB-987945-A (GB)
Title: Method for recovering liquids from vegetative materials
Inventor: CELMER RALPH FRANK
IPC: A23L2/04
Filed: 1963-03-18
Abstract: Liquid having a low solids content is obtained from vegetative materials by adding alpha cellulose fibres substantially free from fines and predominantly in the range of 1-10 mm/s. in length, forming a swollen inter-tangled mass of the fibres uniformly distributed in the vegetative pulp, and reducing the volume of the mass to separate the liquid from residual solids retained by the inter-tangled mass of fibres.  Preferably the fibres are added in a proportion of 0,5-5% by weight.  Preferably they are derived from sulphite soft wood pulp. The volume reduction may be effected by a continuous screw press or by two in series (for the pulp), the juices therefrom being combined. The first of these presses may be replaced by a continuous centrifugal extractor; alternatively, both may be replaced by a hydraulic reciprocating press.  The pulp may be preconditioned by adding pectic-substance-degrading enzymatic material in a proportion of, e.g., 0,2-0,4%.  The pulp may be heat-treated at various stages, and may be macerated prior to the addition of cellulose fibres. Apples in bulk may have the cellulose fibres added prior to disintegration and screw-pressing.  The process may be applied to citrus fruit pulp, cooked prune pulp, grape pulp or aqueous potato waste, or carrots, beets, celery, rhubarb, pears, quinces and pineapples.
