Abstract: 1,158,826. Refrigerators. STAL REFRIGERATION A.B. 12 July, 1967 [4 Aug., 1966], No. 32006/67. Heading F4H. Containers, each having an air inlet and outlet, are cooled during transport or storage by cold air which is discharged from nozzles directed towards and spaced from the inlets, the spacing between the nozzle and inlet and their relative flow cross-sections being such that only air from the nozzle enters the inlets. As shown in Fig. 3, the container wall has an inlet 2 extending from the base of a concave recess 6. The latter deflects part of the air from the nozzle 5 into the ambient atmosphere, the remaining air passing through the inlet. As shown in Fig. 5, the inlet has a radiused inner edge and communicates with a chamber 8 within the container so that the dynamic pressure of the incoming air is substantially converted into static pressure. The nozzle 5 forms part of a fan and duet system serving a plurality of containers. The latter may be provided with closure members which automatically open and close the inlets and outlets when the containers are loaded and unloaded, respectively, into or out of a ship's hold. For road transport air is circulated through the containers by refrigeration units mounted thereon.

Patent GB-320946-A (GB)
Abstract: 320,946. Webb, C. F., and Black, H. D. July 27, 1928. Tickets, issuing. - Relates to machines for issuing strip tickets and consists in using the overrun of the driving motor for actuating the ticket delivery means. The invention is described as applied to a machine of the character described in Specification 282,581 wherein printing is effected by means of a single, rotary type-cylinder co-operating revolubly with an impression roller. A rubber tyred friction wheel 3 is driven by a spring hand 5 from a spindle 8 on which is a sprocket wheel 7 driven directly by a chain 11 from the motor driving the machine. A curved guide plate 12 is mounted on a rocking arm 13, the free end being located close to the surface of the wheel 3, which the guide plate partly embraces, and near the delivery slot 24. The strip 16 is advanced along a guide 27 by pairs of wheels 36, 28 spring-pressed together the wheels 28 being provided with segments 29 corresponding in length to the length of the ticket. The wheel 28 are driven from the shaft 20<x> of the type cylinder. The guide plate 12 supports an impression roller 14 operated as in Specification 282,581. The plate 12 lies between the impression roller 14 and the type cylinder 20 an extension 15 forming a guide for the strip on which bears a spring 17. The plate 12 is provided with an aperture through which the roller 14 projects. A pair of hooks 23 fixed to the cylinder 20 engage the rear end of each printed ticket and push it free from the impression roller so as to lie on a chord of the curve of the guide plate 12 and tangential to the wheel 3. The ticket is now delivered bv rotation of the wheel 3 which being driven direct from the motor enables the overrun of the motor, after the cylinder 20 has been declutched, to deliver the ticket. The corners of the plate 12 adjacent the wheel 3 are bent towards the wheel and maintain the printed portion of the ticket out of engagement with the plate 12. A knife 42 severs the ticket prior to printing.

Abstract: 464,587. Heating by circulation of fluids. REAVELL, J. A. Nov. 23, 1935, No. 32489. [Class 64 (ii)] Oil is heated by passing through crosstubes 11 and then through a jacket 10 above a furnace 2, the oil being circulated through a centrifugal pump 6 and stop valve 8. The heated oil is circulated around a heating circuit indicated by a jacketed pan 16 by another pump 20, the circuit being provided with a control valve 18. When the system is cold, circulation of the oil by the pump 6 is facilitated by connecting the outlet of the pump 20 through a valve controlled byepass 24 to the inlet of the pump 6, the valve 26 being closed. The quantity and velocity of the oil passing through the heating circuit is independent of the quantity and velocity of the oil passing through the heater 1, so that the pump 6 may be of the centrifugal type and the pump 18 may be small and of the positive displacement type. Byepasses 19 may be provided to enable the apparatus 16 to be short-circuited or its temperature to be regulated.

Abstract: 675,884. Gaseous mixtures. PILZ, K., and JOKLIK, A. Dec. 20, 1949 [Sept. 23, 1948], No. 32648/49. Class 55 (ii). A town's gas with a low carbon monoxide content is obtained from natural gas, coal gas, or mixtures, by submitting a portion to cracking in the presence of oxidation gases, then converting the bulk of the carbon monoxide to carbon dioxide and increasing the hydrogen content by passage with steam over catalysts, and finally mixing with untreated gas. Natural gas containing about 97 per cent methane is passed with air over copper oxide catalyst at 800-900‹ C., the product gases being cooled by a water spray to 300-400‹ C. and after reacting with the steam in a converter, being cooled, washed and mixed with fresh natural gas to provide a mixture of CH 4  34.2 per cent, H 2  26.9 per cent, CO 1.8 per cent, CO 2  9.4 per cent, N 2  27.7 per cent. In a coal gas treating plant comprising a cracking oven 3, converter 5, and spray cooler 4, heat exchangers 8, 9 are interposed for preheating the oxidation gas and the gas before conversion. The portion of the gas not subjected to cracking rejoins the cracked stream before the saturator 4 apart from a small amount burnt in the converter with air admitted through an inlet 11. The product gas may consist of CH 4  21.6 per cent, H 2  52.0 per cent, CnH 4  2.2 per cent, CO 1.0 per cent, CO 2  9.1 per cent, N 2  14.1 per cent.

Title: Improvements relating to therapeutic compositions and methods of making the same
IPC: A61K31/40
Filed: 1945-12-03
Abstract: A cell stimulating composition for use in treating wounds and infections and for stimulating the growth of healthy tissues is prepared by distributing therapeutically effective amounts of chlorophyll in a carrier and incorporating therein a material so that the pH of the composition is 6.0 to 8.5.  Preferably the composition should be buffered at this pH range.  Chlorophylls of 15 per cent purity, preferably 70-90 per cent or more, may be used and chlorophyll derivatives such as chlorophyllide a and b, iron and copper phaeophytin, phaeophytin a and b, phactochlorin e and g and copper and iron complexes thereof, phaeophorbide a and b, isochloraphyllin a and b, chlorophyllin a and b, also sodium and potassium salts of any of the foregoing which contain acid hydrogens. The compositions comprise fluid, viscuns or solid preparations, containing water-soluble or water-insoluble chlorophylls, the latter being preferred for the less fluid preparations such as ointments, salves and the like of oily or fatty nature.  Emulsions of chlorophyll or of chlorophyll dissolved in oil, may be prepared by the use of dispersing agents such as certain waxes, ursolic acid, glyceryl and glycol fatty acid esters, soaps such as sodium, magnesium, calcium and zinc oleates and alkali metal salts of sulphuric acid esters of long chain alcohols.  More viscous materials may have as base materials one or more vegetable oils such as cottonseed, olive, linseed, soyabean and eucalyptus oils, liquid paraffin, lanolin, lard, aquaphor (eucerin), petrolatum, monolene (propylene glycol stearate), cholesterols, stearic and palmitic acids and other higher and lower fatty acids, their alcohols and esters thereof such as glyceryl stearate, palonitate and oleate.  Fatty preparations containing varying amounts of water have as an essential constituent water absorbing materials such as lanolin and preferably, in addition, 5 to 10 per cent glycerine. Anhydrous preparations contain a buffering agent so that in contact with water or aqueous secretions during application to the body, the compositions will have the desired fat.  Ointment bases containing free fatty acids are first treated with aqueous alkali e.g. solutions of sodium or potassium hydroxide or carbonate to saponify the fatty acids and then adjusted to the desired pH.  Any therapeutically compatible non-irritant buffering agent may be used in these compositions e.g., a strong inorganic acid or base with an appropriate acetate, citrate, acid phosphate or phthalate, boric acid and sodium borate, and citrus pectin.  The examples describe, inter alia, aqueous and oily compositions for injection.

In a further embodiment, instead of a table top, two connection rods extend across the top of the heater and can be used to suspend towels. The frame, which may be of aluminium or stainless steel, has fitted in its uprights lamps to illuminate the heating element through slits in the uprights.
