Abstract: 1505215 Prosthetic joints GLASROCK PRODUCTS INC 12 April 1976 [11 April 1975] 14864/76 Heading ASR In a prosthetic joint, such as a hip joint, Fig. 2, or a finger joint, Fig. 5 the parts which come into contact with the bones into which the joint is to be implanted are coated with a porous polymeric material having certain specified properties such that the body tissue grows into the pores of the polymeric material, thereby anchoring the device firmly in place. The polymeric material has an average pore diameter of 50-300Ám, a minimum pore volume of 30% and a melt index of 0.005-5 and the network of pores contains no straight paths longer than the diameter of the largest pore. Suitable such polymeric materials are polyethylene having a density of 0.945 to 0.965g/cc and polypropylene having a density of 0.912 to 0.914g/cc. The hip joint prosthesis shown in Fig. 2 comprises a femoral component which may be made of a corrosion-resistant alloy, and a socket component 26 which may be made of non-porous ultra-high molecular weight polyethylene; the coating of the porous polymeric material is applied to the shank 22 of the femoral component and the convex surface 30 of the socket component, the head 14 of the femoral component and the concave surface of the socket component being left exposed. The socket component may be provided with spikes to hold it in place until the surrounding tissue grows into the pores in the coating material. The shank of the femoral component may be of I-shaped cross-section and may be provided with openings (16) Fig. 1 (not shown) to provide a mechanical interlock with the coating material. The finger joint prosthesis shown in Fig. 5 comprises two hinged components which may be made of non-porous ultra-high molecular weight polyethylene; the porous coating is applied to the stem portions 38, 40 which are inserted into the respective intra-medullary canals of adjacent finger bones.

Filed: 1974-04-04
Abstract: 1423799 Gas turbine combustion apparatus GENERAL MOTORS CORP 4 April 1974 [12 April 1973] 14998/74 Heading F1L [Also in Division F4] Gas turbine combustion apparatus comprises a casing 2 containing a liner 3 having a wall 12 defining a primary air inlet 14, prevaporization  zone 15, flare 16, and combustion, residence and dilution zones 18, 19, 20 respectively. Casing 2 has an enlarged upstream portion 7 receiving  through pipes 10 pre-heated air, some of which flows to primary inlet 14, whilst the major portion of the remainder is caused by baffle 54 to flow through a cooling path 52 defined between an imperforate portion of liner 3 and a shroud 47 before entering dilution zone 20 through holes 46. Shroud 47 is freely mounted by angularly spaced plates 48, so welded to liner 3 and engaging slots in the shroud. Distortion of the latter is prevented by spacers 51. The upstream end of liner 3 is supported via struts 38 by a fuel supply ring 28 connected through fuel pipes 30 to a mounting 31. Fuel is injected from chamber 34 through tangential ports 35 in ring 28 to mix with and be vaporized by the pre-heated primary air flowing through and around the ring. Struts 38 do not produce any swirl in the air-flow. The fuel/air mixture is guided from zone 15 through flare 16 by a curved centrebody 39 carrying V-shaped sheet metal struts 40 defining flow passages 42. Centre body 39 and struts 40 are hollow to assist conduction of heat from combustion zone 18 to the fuel/air mixture. Mixing of the latter upon reaching combustion zone 18 is promoted by vanes 44 which induce toroidal vortex flow.

Title: Process for the preparation of isocyanate polyaddition products
Inventor: MCELROY WILBUR RENFREW
IPC: C08G18/08
Filed: 1963-04-17
Abstract: Isocyanate poly addition products are formed by reacting an organic polyisocyanate with a compound containing active hydrogen atoms in a two-phase system in a liquid which is inert with respect to the reactants and in which one of the reactants is not more than 5% soluble by weight and in which one of the other reactants is substantially soluble.  Active hydrogen-containing compounds may be: polyethers, polyesters, polyacetates, polyesteramides and low M.W. compounds, e.g. polyhydric alcohols, diamines, aminoalcohols and aminoacids.  The polyisocyanate may be aromatic or aliphatic, many polyisocyanates are specified.  The inert liquid may be an aliphatic or aromatic hydrocarbon, ester, ether nitrile, thioether, sulphoxide, ketone or halogenated hydrocarbon.  In Example (1) a solution of 4,41-diphenylmethane diisocyanate in Stoddard solvent was reacted with polyethylene adipate with stannous octoate as catalyst and agitated. In Example (4) a mixture of trimethylolpropane and butane diol was added with agitation to a solution of tolyene diisocyanate in Stoddard solvent.  In other examples, the solvents used were (5) n-heptane, (7) isooctane, (10) n-hexane, (15) xylene.

Title: Improvements in or relating to relaxation oscillation generators embodying gas-filled discharge tubes
IPC: H03K4/86
Filed: 1951-06-26
Abstract: 706,258. Valve circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 26, 1951 [June 29, 1950], No. 15137/51. Class 40 (6) A relaxation oscillator comprises two gas-filled cold cathode tubes in which the cathodes are interconnected and taken to a negative supply source, the triggering electrodes and anodes are each coupled together via a capacitor and are connected via resistors to a positive supply source, an output voltage being derived from the anode circuit of at least one of the tubes. The Figure shows a relaxation oscillator comprising cold cathode gas-filled tubes B1, B2 in which if say tube B 1 is conducting at any instant then capacitor C1 charges from the tapping on battery Ba via resistor R2 and the conductive path a1, kl in tube B1 until tube B2 fires the resultant fall of potential at the trigger electrode o2 and anode a2 being applied via capacitors C1 and C2 respectively to extinguish tube B1. Capacitor C1 then recharges via resistor R1 and the conductive path o2, k2 in tube B2 until tube B1 fires when tube B2 is extinguished and the cycle is repeated. The period of conductivity of tubes B1 and B2 may thus be independently controlled by adjustment of the values of resistors R1 and R2 respectively and the relaxation period is also independent of changes in the load impedance. Output pulses may be taken at U from the anode circuit of tube B1 or the circuit may be used as a sawtooth generator by using the voltage developed across capacitor C1.

Abstract: 572,971. Automatic control systems for D.C. motors. IGRANIC ELECTRIC CO., Ltd., MAYNARD, S. P., and BEDFORD, J. M. Sept. 17, 1943, No. 15294. [Class 38 (iv)] Speed.-To match the speed of a direct current motor with another, a switch controlling a resistance in its shunt field circuit has its duration of opening and closing controlled respectively by electronic valves T1 and T2, the ignition instants of which are determined by the charging of condensers m, n. The charging times of these condensers are simultaneously variable in opposite senses by means (not shown) responsive to the difference in speed of the motors, for example by a jockey roller responsive to the tension in, or the length of a loop of, material which is being operated on by the motors. The charging circuits comprise respectively resistances a, b-e and f, l-g and the condensers or the resistances b-e, l-g may be controlled by the speed difference. The valve circuits are arranged as shown so that each valve is non-conducting until the potential across the condenser in its grid circuit has risen to a predetermined value. When valve T1 conducts, the switch 1b shortcircuits the resistance p-q in the field circuit of the controlled motor SM. A switch 1a is also closed so that a relay 2 energizes as soon as valve T2 conducts and a switch 2a opens to restore the circuits to their initial condition.
