Title: Improvements relating to machine parts with inserted valve seats
IPC: F01L3/18
Filed: 1950-03-08
Abstract: 668,962. Construction and cooling of fuel injectors and of valve 'seats, guides and cages. SULZER FRERES SOC. ANON. March 8, 1950 [March 9, 1949], No. 5848/50 Classes 7(ii), 7(iii) and 7(vi) [Also in Group XXIX] To prevent leakage of circulating cooling medium from an annular space 5, Fig. 1, between the seat 6 of a poppet valve 3 and a machine part such as the head 1 or other appropriate part of an I.C. engine cylinder, the seat 6 is formed, on either side of the space 5, with a resilient portion 7 having a sealing surface co-acting with a corresponding surface on the head 1. The seat 6 is located both frictionally and by a swagedin ring 10. Cooling medium may be supplied simultaneously to two valve seats via a common inlet pipe 16, Fig. 4, the medium escaping either by a co-axial outlet pipe 17 as shown, when the valve seat cooling system may be independent of that for the cylinder head generally, or through openings 14, Fig. 1, to main cylinder head cooling spaces 15, the flow through the openings 14 constituting part or all of the main flow. The valve seat may form part of a valve cage, two or more seats being individually or mutually supplied with coolant passing to a main cooling space in the manner of Fig. 1, or a valve guide 27, Fig. 6, in the cage 25 being also cooled, when the operative medium from a supply space 28 flows between the cage and guide before reaching the space 31 in the seat via passages 29, 30 and escaping therefrom via a bore 33 or parallel bores in a cage rib 25a. In a cylinder head 34, Fig. 9, having two inlet valves, two exhaust valves and a central fuel injector 35, coolant admitted through a common inlet pipe 36 to an annular chamber 37 surrounding the injector 35 passes through passages 38 to annular spaces 39 around the valve seats 40, which may be as shown in Fig. 1, and escapes into the main cylinder head cooling space 41 via passages 42. A similar arrangement may be applied to a cylinder head having two exhaust valves only, or one inlet and one exhaust valve. The arrangement of Fig. 9 may be modified by providing a pipe connection to each passage 42, when the outflows from the seats may be passed individually to the outside or into separate cooling spaces of the head or other parts, whilst by reversal of the direction of flow the valve seats may be individually supplied. With opposed-piston engines, the invention may be used in a central zone of the cylinder.

Title: Improvements in luminescent materials
Inventor: RANBY PETER WHITTEN
IPC: C09K11/71
Filed: 1951-03-12
Abstract: 746,272. Luminescent materials. THORN ELECTRICAL INDUSTRIES, Ltd. March 4, 1952 [March 12, 1951], No. 5942/51. Class 39 (1). Luminescent material comprises the pyrophosphates of calcium, and of one or more of magnesium, strontium, baiium or zinc activated with tin or with both tin and manganese, the proportion of the tin being not less than 0.05 per cent, by weight, of the material, the composition of the pyrophosphate being such that the molecular ratio of metal oxide (excluding the tin activator) to phosphorous pentoxide lies between the limits 2:0.9 and 2: 1.4 inclusive and the amount of calcium constituting not more than 98 molecular per cent of the total metal (excluding the tin or the tin and manganese activators) in the material. The proportion of tin may be not more than 10 per cent, by weight, of the luminescent material. Up to a half of the metal content (excluding the tin activator) of the material can be replaced by manganese. In preparing the material the temperature is kept below the sintering temperature. The tin in the starting material can be in the stannous state, and the heat treatment carried out under non-oxidizing conditions by heating the mixture in a plugged tube or a covered crucible or by heating it in a non- oxidizing atmosphere of steam and/or nitrogen of mixtures of hydrogen with steam and/or nitrogen. Alternatively, the tin can be in the stannic state and the heat treatment carried out under conditions such as to reduce the tin to the stannous state. The material can be made by preparing the pyrophosphate matrix without the tin and then incorporating the tin and heating under non-oxidizing conditions. Tables showing the different luminescent colour effects obtained with different proportions of constituents and activators and examples of preparation of specific materials using manganese phosphate and stannous chloride or oxide as activators are given. Specifications 512,154, 578,272, 645,502, 746,271 and 746,289 are referred to.

Title: An improved process for the production of artificial silk from viscose
IPC: D01F2/08
Filed: 1931-03-05
Abstract: Artificial silk is produced from viscose which is clarified by the addition at any stage in the production of the viscose of a small amount, i.e. less than 2 per cent, of a sulphonated fatty acid, fat or fatty oil having a high content of organically bound sulphuric acid, the amount of non-sulphonated fat or fatty oil in the sulphonated product being so small that it shows no turbidity with an excess of lye.  The sulphonated products may be obtained in known manner by sulphonation with an excess of sulphuric acid in the presence of acid chlorides or anhydrides; liberated glycerine need not be removed.  In an example, 0,1 per cent or less of the product sold under the registered Trade Mark "Praestabit" is added to the viscose.  The addition may be made to the soda cellulose or to the carbon disulphide used for xanthogenation.  Enhanced results may be obtained by the addition of a small amount of an alkylated aromatic sulphonic acid, e.g. iso-butyl-naphthalene-sulphonic acid.
