Title: Monitoring eccentricities of members having an interior
IPC: G01B15/00
Filed: 1971-06-01
Abstract: 1357592 Measuring eccentricities SCHWEISSINDUSTRIE OERLIKON BUHRLE AG 1 June 1971 [4 June 1970] 18462/71 Heading G4H In a method and apparatus for monitoring eccentricities of interior members relative to surrounding sheaths such as in sheathed welding rods, the assemblies (sheathed rods) 22, Fig. 1, are moved sequentially through a narrow parallel beam 23 from an energy source 20 which beam is differently absorbed by the material of the members relative to that of the sheaths, the periods when the radiation passing through an assembly is between two predetermined limits as an assembly moves into the beam and as it passes out of the beam are determined, the difference between the durations of the two periods is determined, and the absolute difference values for a predetermined number are added to obtain an average indication. The radiation which may be X-rays is detected by an ionization gauge 24 and indicated on a measuring recorder 29 whereby the predetermined limits may be ascertained for setting into comparator 28 by means of terminals 43, 44. The output of a pulse generator 26, the frequency of which is related to the speed of conveyance of the assemblies, is gated to an updown counter 30 during the two periods and the individual absolute values of eccentricities excluding those shown to be excessive by comparison with a reference 45 in a comparator 31 are applied to an adder 33, the readings from which are stored and indicated and which may be used to effect an adjustment to the manufacturing machinery and to a counter 34 for subtracting from the number used to determine the mean value. The number, and extent of eccentricity of rejects is stored and indicated in 39, 42 and the store contents are indicated when the number of measured assemblies equals a preselected number. The conveyed assemblies may be set into parallel alignment by a unit 52 and the reading head may be caused to traverse different cross-sections along the lengths of assemblies. A statistical analysis is included. Recorder 29 may comprise logic circuitry to determine the time periods corresponding to wire and sheathing diameters in order to set the thresholds.

Abstract: 430,212. Lubricating crank pins. WEIR, Ltd., G. & J., Holm Foundry, Cathcart, and PULLIN, C. G., 104, Queen's Drive, both in Glasgow. June 22, 1934, No. 18481. [Classes 12 (ii) and 12 (iii)] One or more spring - loaded non-return valves is, or are, incorporated in a crank shaft so as to set up a predetermined resistance to the oil flow to the crank pin journals. For a two-throw crank-shaft 12, oil under pressure flows through passages 13.. 17 to an annular space 10 having ports 11 closed by a spring loaded valve 3. When the oil pressure exceeds the spring load oil passes through the ports 11 and passages 21, 23, 26, 22, 24, 27 to the crank-pin bearings 28, 29. The invention is particularly applicable to crank pins having roller type bearings.

Abstract: 669,467. Ice-making ; ice-breaking apparatus. FLAKICE CORPORATION. July 14, 1947 [July 24, 1946], No. 18685/47. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 14, 1947.] Class 29. Ice-making apparatus of the kind in which water from a distributing tank is made to flow down a group of vertical tubes subjected to freezing to form ice in the tubes and to thawing to release the formed ice, comprises a row or bank of iceforming tubes presenting a pair of parallel side surfaces closely flanked by evaporator sections connected by an automatic control, other than a time cycle control, to a liquid refrigerant supply during freezing and to a hot gaseous refrigerant supply during thawing. The apparatus comprises a storage chamber 4 and an upper part 6 containing a refrigerating system the evaporator 22 of which is coiled around an aligned bank of sixteen square-section tubes 18 down which water is sprayed from a header 28 to form ice sticks, the excess water being drained to a tank and pumped back to the header 28. Between each pair of tubes 18 is a fin 21 which is drilled to locate the evaporator coils 22. The header 28 is provided at each tube 18 with a nipple 30 having holes 32 from which water sprays on to the tube sides. When harvesting, the freed rods of ice are broken by a cutter 42, the pieces falling on to a grating 35 and then into a shoot 40 from which the pieces fall through an opening 12 into the storage chamber 4. The cutter 42 comprises a bar 48 extending the lengths of the bank of tubes 18 and carrying ice picks 50. The bar 48 is suspended from pivots 47 and is oscillated during harvesting by motor driven cams 52, the bar being normally urged away from the ice-rods by a spring 60. When making large pieces of ice the ice-rods rest on the grating 35 during cutting but if small ice pieces are required a stop 160 is inserted in the path of the ice-rods by a control finger 172. The. refrigerating system is shown schematically in Fig. 8. During freezing the solenoid operated valves 92, 110 are closed and solenoid operated valve 114, open. The refrigerant proceeds from a compressor 66 to a condenser 72 and then by way of pipe 74, heat exchanger 76, evaporator 22 and pipe 86 back to the compressor. Condensing water flows from a pipe 94 to the condenser and then to a hot water storage vessel 98 the outlet 104 of which is controlled by a. valve 102 controlled by the pressure in the compressor output line. During harvesting, the valves 92, 110 are open and the valve 114 closed. Hot refrigerant gas is supplied to the evaporator 22 by pipe 108 and returns to the compressor by way of the vessel 98 where any condensate formedin the evaporator is vaporized. Make-up water for the ice tubes is supplied to a float controlled tank 34- during the harvesting period. The operation of the valves 92, 110, 114 of the cutter 42 and of the water circulating pump are controlled in accordance with the temperature of the ice tubes 18 by a thermostatic capsule 122 so that the freezing and harvesting cycles are completely automatic.

Abstract: 426,475. Fuel - - injection pumps. OLDHAM, R., Holmwood, Cleethorpes, Lincolnshire. July 4, 1933, No. 18902. [Class 102 (i)] In a fuel-injection pump, of the type in which a recess or passage 5, Fig. 3, in the plunger connects a passage 3 in the cylinder, communicating with the pressure space, and one or more relief ports 8, the passage 3 is formed as a recess in the surface of the cylinder bore.

Title: Methods for increasing the alcohol yields from cereal worts
Inventor: STOWELL KEITH CHRISTOPHER
IPC: C12C7/00
Filed: 1964-05-07
Abstract: The yield of alcohol produced in the fermentation by yeast of a cereal wort is increased either by adding cereal malt in a finely-divided form (flour) and containing limit dextrinase to conventionally-produced wort to be fermented (or to the crushed cereal malt for preparing the wort) or by fermenting a wort prepared by digesting cereal malt in a finely-divided form and containing limit dextrinase, with water at a temperature sufficiently low to avoid loss of limit dextrinase.  With the latter procedure, digestion of cereal malt flour (containing the starchy endosperm and some of the aleurone layer, but from which the husk and bran have been discarded) with water to form fermentable wort and fermentation of the wort with yeast may proceed simultaneously at a temperature of 80 DEG  - 85 DEG F. for, say, 72 hours. missing page 252
