Patent GB-891887-A (GB)
Title: Improvements in and relating to hypodermic syringes
IPC: A61M5/20
Filed: 1958-05-30
Abstract: 891,887. Surgical injection appliances. STATO A.G. May 30, 1958 [May 31, 1957], No. 17298/58. Class 81 (2). An automatic, hypodermic injection appliance having a spring-loaded plunger for inserting the needle and making the injection, has an end cap which guides the ampoule and needle and also, when detached and inverted, is used for compressing the spring for subsequent use. The spring 20 is held within the tubular body 1 and is compressed, at one end, against a locating member 11 in the body and, at the other end, against a flange on the plunger assembly 9. It is normally held compressed by spring blades 10, attached to the assembly 9, the upper ends of which pass through and engage over the upper face of the member 11. However, when the release knob 13 is depressed, the cylindrical insert 14 compresses these blades radially so that they are disengaged from the member 11 and the plunger 8 is driven downwards. Initially it contacts the ampoule stopper 31 and, thereafter, the resistance to flow of the liquid medicament 30 through the needle 29 causes the ampoule and needle to be projected rapidly downwards, after which the contents are ejected through the needle. The lower end of the needle is initially sealed by a rubber stopper 35 and the ampoule is fitted with a tubular sheath 36, which guides it as it moves downwards. This sheath is held in the end cap 3 to hold it rigid during use but, after an injection has been made, the end cap 3 is removed, together with the ampoule, and then inverted so that its end 5 can be used to bear against the plunger and compress the spring 20. The release knob has a form of bayonet connection with the body, so that it can be locked to prevent unintentional discharge of the contents.

Abstract: 1,260,225. Glass melting furnaces. CORNING GLASS WORKS. 3 April, 1969 [8 April, 1968], No. 17452/69. Heading F4B. [Also in Divisions C1 and H3-H5] In a vertical-flow, glass melting and refining furnace 10, the heat energy is applied about the peripheral wall of the furnace to at least two different levels to maintain turbulent or circulating flow in an upper melting zone and to refine the molten material in a lower quiescent zone. Electrodes 44A-44C, of molybdenum, cause circulation of glass in zone "A" along paths 54, whilst electrodes 58A-58F cause circulation in the opposite sense along paths 64 in zone "B", the result being virtually no circulatory currents in the refining zone "C" from which the glass exits via an opening 32. In an alternative furnace 10, Fig. 5, the raw materials or batch 14<SP>1</SP> forms a downwardly convex body projecting a substantial distance into the molten glass, and power is supplied to three tiers of electrodes at different levels at differing rates, the greatest power input being at the highest level. The furnace may be heated by other means than electrodes, e.g. by gas burners.
Patent GB-135890-A (GB)
Title: Improvements in or relating to Internal Combustion Engines and the like.
Inventor: HOWE ROBERT
IPC: F01P1/02
Filed: 1918-10-26
Abstract: 135,890. Howe, R. Oct. 26, 1918. Valve-gear.-Air is compressed in the end of a cylinder remote from the combustion chamber and cooled before its admission to the combustion space, the transfer of the charge commencing before the opening of the exhaust valve. A portion of the air compressed in the pump end of the cylinder may serve for actuating an exhaust valve in the cylinder head and an admission valve for the fuel. In the construction shown in Fig. 1, a portion of each charge compressed in the lower end of the cylinder 1 is transferred to the space above the piston through ports 10, the charge being cooled by water circulated through pipes located in the transfer chamber 2. The remaining portion of the compressed charge is transferred through passages 8, 19<a> to a pipe 19 leading to a valve-controlled passage 21 opening into a chamber containing a piston 13 secured to the stem of an exhaust valve 11. The valve is held to its seat by a spring 12 and also by fluid pressure which exists in the pipe 19<b> until the piston uncovers the ports 10 towards the ends of its nut-strokes. Air escapes from above the piston 13 through a passage 25, which may be throttled by a needle valve 20 to delay the closing of the exhaust valve. A modification is described in which an extension of the piston compresses in a co-axial cylinder the air for actuating the exhaust valve. According to a further modification, each cylinder is associated with a double-acting pump in the ends of which are compressed air, and fuel, or a mixture of fuel and air respectively. Air may be transferred to the fuel-compression end of the pump to dilute the charge. The air is delivered to the upper of the two chambers adjacent the pump end of the working cylinder, the combustible charge being cooled before its transfer to the combustion space through a valve actuated by fluid pressure. The valve is held closed by air compressed in the pump end of the working cylinder; when the pressure is withdrawn, the pressure of the combustible mixture is sufficient to open the valve against the pressure of the air in the combustion space.

Abstract: 1441186 Liquid meters JOHANN BAPTIST ROMBACH 22 April 1974 [21 April 1973] 17584/74 Heading F1A In a liquid meter, e.g. for metering fuel, which has two metering chambers Ml, M2 alternately connected to an inlet or outlet of the meter by an oscillating valve and separated by a double-acting reciprocating piston 14, the valve comprises two valve discs 4a, 4b fixed on a rotary shaft 2 and each having a single port and is oscillated by a lever 7 and a linkage formed by two pivot arms 8, 9 which are acted upon by abutments 15, 16 carried by the piston 14. The lever 8 pivots about a pivot 12, lever 9 about a pivot 12b and the two levers are pivoted together by a pin 8a to which is also connected one end of the lever 7. Two tensioned springs 11 stretch between pivots 12 and 12a to act as a quick throw mechanism. When either of the stops 15 or 16 displace the linkage from the position shown in full outline in Fig. 1, the springs deform the linkage to a respective one of the positions shown in pecked outline during which movement the valve is displaced to connect valve chambers VR1, VR2 to the inlet and outlet respectively or vice versa, the chamber VR 1 being directly connected to the metering chamber M1 and the chamber VR2 being connected to the metering chamber M2 by a passage UK. The abutment 16 is adjustable by a screw 17 for calibration. The shaft 2 may be connected to a shaft of a mechanical counter or to an electronic digital counting mechanism via a device which converts oscillation of the shaft 2 to electrical pulses. The device has a shaft which carries electrical contacts and is connected to the outer one of a pair of magnetic discs 23, the inner one being connected to the shaft 2 as shown in Fig. 1.

Title: Improvements in apparatus for mixing gas and air in internal combustion engines
IPC: F02M21/04
Filed: 1919-07-14
Abstract: 152,426. Johnson, W. P., and Schofield, H. July 14, 1919. Regulating.-Relates to apparatus for mixing air and gas of the type in which the quantity and the composition of the mixture are varied by angular and axial adjustments of a cylindrical throttle valve 20 having peripheral ports 24, 25 for the inlet of gas and air respectively and a port 26 for the outlet of the mixture. According to the invention, the air-inlet port 25 is of the same axial length as the air-inlet port 13 in the casing, whilst the gas-inlet port 24 is shorter and the mixture-outlet port 26 longer than the co-operating ports 11, 15 in the casing by an amount such that these ports are not throttled by the axial adjustment of the valve, and a spring 23 is arranged between one end of the valve and the casing to hold the valve towards one extreme position. In the arrangement shown, there are four similar air ports 25 in the valve. The angular adjustment of the valve for varying the quantity of mixture is effected by an arm 32 on the valve spindle, and the axial adjustment for varying the area of the air ports relatively to the areas of the gas and mixture ports is effected by turning a nut 30 which works over graduations on the spindle.

The acyl radical A is preferably one that is stable under the reaction conditions, e.g. phenylacetyl or phenoxyacetyl, or may be a radical giving a desirably active cephalosporin, e.g. thienylacetyl or α-amino-phenylacetyl. If the acyl radical contains a group which would be affected by the reaction, e.g. amino, carboxyl or hydroxyl, this is conventionally protected before the reaction and subsequently de-protected. The esterifying group R is preferably one that is easily removable without affecting the remainder of the cephalosporin molecule, e.g. p-methoxybenzyl, di-p-methoxyphenylmethyl, trityl, diphenylmethyl, benzoyloxymethyl, phenaeyl, p-bromophenacyl, benzhydryl, tert.butyl and trimethylsilyl, which groups are removed by mild hydrolysis. Alternatively the esterifying group may be one that is removed by reduction, such as benzyl, o-nitrobenzyl, 4-pyridylmethyl, 2,2,2-trichloroethyl, phenacyl or p-bromophenacyl. The ring expansion is suitably performed using 0À03 to 0À1 mole phenacyl bromide per mole of penicillin sulphoxide ester, in a solvent such as dimethyl-sulphoxide, -formamide or -aniline, n-butanol, ethylene glycol, diethylene glycol dimethyl ether, methyl isobutyl ketone, methyl amyl ketone, butyl acetate or xylene. The solvent should be one of as high a boiling point as is practicable, the preferred reaction temperature being 100-200‹ C. (e.g. 130‹-170‹ C.). The product is recovered by pouring the reaction mixture into ice-water, causing the desired cephalosporin ester to precipitate. It may be separated by filtration or extraction with a water-immiscible organic solvent (e.g. ethyl acetate) followed by evaporation of the solvent, and is then purified by re-crystallization.
