Title: Internal combustion engine with four valves for each cylinder
IPC: F01L1/26
Filed: 1963-01-02
Abstract: 960,396. Valve gear. A. C. SAMPIETRO. Jan 2, 1963 [Jan. 3, 1962], No. 280/63. Heading F1B. In an I.C. engine having spring-controlled poppet valves controlling two inlet ports 2, Fig. 1 and two exhaust ports 3 disposed on opposite sides of a central plane through the cylinders, a single camshaft 8, located above the cylinder parallel to the central plane, has two cams 11, 13 for each cylinder and two rocker arms 16, 31, Fig. 2 co-operate with each cam so that each cam operates an inlet valve and an exhaust valve in sequence. Each pair of cams act through rollers 41 on rockers 31 to open two inlet valves 15 and act through rollers 24 on rockers 16 to open two exhaust valves 14. Rockers 16 are pivoted on shaft 17 mounted in camshaft bearing lugs 7. A cam 12 operates fuel injector 44 mounted on rocker 13. In modifications the fuel injectors and exhaust valves are operated by rockers having spherical mating surfaces engaged by shafts which are rigidly secured to the cylinder head. In a further modification the rockers are mounted on supports 55, Fig. 7. When cam lift commences sleeve 57 is pushed upwardly trapping oil in the space below a spring-loaded apertured washer 62 thus forcing washer 62 against a seat on the end of support 55 and stopping upward movement. During the non-lift part of the cam rotation, oil under pressure passing through bore 56 unseats washer 62 causing the sleeve 57 to take up any clearance present in the valve gear. In a further embodiment the rockers are arranged to radiate from the cylinder vertical axis and are actuated by conically-shaped cams acting through conical rollers. The fuel injector nozzle may be replaced by a spark ignition plug.
Patent GB-1015831-A (GB)
Title: Improvements in or relating to methods and composition of chillproofing
IPC: C12H1/00
Filed: 1964-01-03
Abstract: In order to test whether or not an extract of a fungal micro-organism is suitable for the satisfactory chillproofing of beer, samples of beer are treated with the extract, and the amount of chillhaze in the samples is determined and compared with the amount of chillhaze in similar samples similarly treated with a standard chillproofing formulation. A preferred procedure involves storing fermented but unchillproofed beer in the cold and protected from exposure to air, filtering, carbonating and bottling the beer, removing air from and sealing the bottles, introducing the fungal extract under test into the bottles (this involves opening the bottles and re-sealing them), pasteurizing, storing in the cold, determining the amount of chillhaze in the bottles and comparing this with the amount of chillhaze in similar bottles similarly treated with a standard chillproofing formulation.  The following fungal micro-organisms are suitable: Aspergillus niger, Aspergillus awamoris, Aspergillus usami and Aspergillus phoenicius.  The following fungal micro-organisms are stated to be unsuitable: Aspergillus oryzae, Aspergillus wentii, Mucor delamar, Amylomyces rouxii, Penicillium oxalicum, Penicillium casei and Penicillium janthinellum.  The aqueous extract of the fungal organism is preferably treated to inactivate limit dextrinase, as by lowering the pH temporarily to 1.5-2.0. The suitable fungal extracts may be employed in synergistic combination with such chillproofing proteolytic enzymes as papain, ficin, pinguinain and bromelain.  According to an example, a wheat bran mash is prepared from wheat bran, wheat flour and water, and is sterilized.  About 125 g. of the sterile mash is inoculated with an actively growing culture of Aspergillus niger, After suitable growth at 30 DEG C., the resultant bran-growth product is dried at low temperature. About 10 parts by weight of water is then mixed with the bran-growth product with continuous stirring or shaking for about an hour.  Liquor expressed from the wet bran by pressing, centrifuging or filtering, is tested, either directly or after concentration, as to its suitability for satisfactorily chillproofing beer, by a comparison of turbidity measurements on beer thus treated with those obtained employing papain of a known activity in various concentrations. The fungal chillproofing extracts may be added to fermented beer as it goes into storage, or to wort before, at the commencement of, or during fermentation, or a portion may be added to the fermenter and a second portion added to the fermented beer. Concentrations of 1-2 lbs. of the fungal extract per 100 barrels of beer are suitable. When employing the combination of papain and the fungal extract, it is possible to reduce the amount of papain from 1 lb. to about 1/3 -\ba1/2 lb. per 100 barrels, and the amount of fungal extract to only one-third or one-half of the normal amount required as the sole chillproofing agent.

A standard mass, for use in the measurement of the density of cigarettes in cigarette-making machines by beta-ray absorption, is made by subjecting a cellular thermoplastic resin, e.g. expanded polystyrene to heat and pressure to raise its density to the required standard. In one method of moulding the mass it is first shaped to the diameter of the finished rod and then brought to the required density by heat and pressure. In another method the material is compressed to the correct density and then cut to the required shape. In examples (1) a rod of expanded cellular material is placed in a tubular mould of the same diameter, metal plugs being inserted at each end and screw-pressed inwards while the mould is heated until the required density is reached ; (2) a mould 1 is used consisting of a metal channel 2 with removable ends 3 and having a block 4 which is a sliding fit in the channel 2 and which can be forced down to a fixed distance from the base of the channel by screws 5, pieces 6 determining this distance. A piece 10 of expanded cellular polystyrene is first cut to a specified shape and then placed in the mould 1 whereupon the material is heated to 50‹C. for 20-30 minutes. The screws 5 are then operated to bring the material to the required density and the finished block removed and ultimately machined to the shape of a cigarette rod.
