Title: Process of and apparatus for sterilising beer
IPC: C12H1/18
Filed: 1930-08-07
Abstract: 355,010. Sterilizing beer. BERNDORFER METALLWARENFABRIK A. KRUPP AKT.-GES., Berndorf, Austria. Aug. 7, 1930, No. 23730. Convention date, July 10. [Class 49.] Beer is sterilized by heating it to about 100‹ C. by passing it while under a pressure of about 10-15 ats. in the form of a layer or film not over 1 mm. thick over heated surfaces coated with or consisting of silver, nickel or other germicidal metal. In the method described, the beer at a pressure of about 15 atmospheres enters through a pipe A a preheater in which it passes between tubes B, C and is heated by hot sterilized beer passing, in counter-flow between tubes C, D. The beer next flows through pipe E to the sterilizer where it is heated to 100-110‹ C. in a chamber F the walls of which consist of or are coated with germicidal metal and are not more than 1 mm. apart. Heating is effected by steam chambers G, H, the beer being exposed to the sterilizing temperature for a few seconds only. The beer next passes to the preheater where its cooling is accelerated by cold brine passing through a jacker L, and leaves the apparatus at storage temperature through a throttle coil M in which its pressure is gradually released.

Title: Apparatus for supervising the operation of driving motors of stationary or movable machines
IPC: C08K5/57
Filed: 1954-08-16
Abstract: 751,449. Registering running time of machines. LEHMANN, E. Aug. 16,1954, No. 23836/54. Class 106 (4). Apparatus for registering the running time of a motor comprises a pendulum 2 operating a counter mechanism drive through a ball click and ratchet wheel, the drive including a driving member 20 secured to a helical spring 21 serving as a slipping clutch and frictionally connected to a driven member 23. When the motor in a stationary or movable machine is running, vibrations cause the pendulum 2, whose weight is supported by a spring 9, to oscillate between stops 10, 11. At each upward stroke of the pendulum 2 a disc 124 secured to a bush 13 carrying a gear-wheel 14 is advanced through ball-andratchet-wheel, reverse movement on the downward stroke being inhibited by balls 123 cooperating with ratchet plate 127. This intermittent drive to the wheel 14 is transmitted to a gear-wheel 20 to which is connected a helical spring 21 which is wound with pre-tension on the end of a shaft 23 of clockwork having a balance spring, but no main spring. The force exerted by the wheel 20 on the spring 21 tends to uncouple it from the shaft 23 so that it acts as a slipping clutch. The clock is thus driven only during the running of the motor and may indicate the running time per shift while.a counter 6 is driven through a worm-shaft and drive 27, 28 to register total running time. A signal may be given when a regular overhaul or service is required.

Filed: 1935-08-29
Abstract: Light weight waterproof building-slabs containing from 85 to 95 per cent of sawdust, and made resistant to moisture by the use of rubber, are made by mixing sawdust, to which may be added a small amount of asbestos or other fibre such as peat straw or wood fibre, with an aqueous emulsion of asphalt containing at most 10 per cent of asphalt, forming a cake, pressing and drying at high temperature and pressure.  The rubber for water proofing is either added to the asphalt emulsion or is applied as a separate layer on the outer surfaces of the slab.  The slabs may be covered with layers of paper or pasteboard which may be covered on the inside with rubber so that they are vulcanized on during the pressing.  Similar layers may also be provided in the interior of the slabs.  Apparatus for forming, pressing and heating the slabs comprises a number of iron frames, each resting on an iron plate and having a top plate fitting into the frame.  A flat spiral steam heating coil rests on the top plate.  A number of frames with top and bottom plates and heating coils are assembled in a pile and pressed down.  In an example, a composition comprises a mixture of 5 parts of asbestos and 95 of sawdust, and sufficient of an emulsion containing at most 10 per cent of asphalt to make a paste.  The paper or pasteboard for covering the slabs is impregnated with asphalt and coated on one side with rubber by applying and drying a rubber emulsion containing 100 grams of 70 per cent latex, and 5 grams of sulphur per litre.  A sheet of the treated paper is placed on the bottom plate of the mould, sufficient composition is inserted, a sieve loosely fitting on the frame is pressed down to remove superfluous emulsion, a top layer of paper is applied with the rubber side downwards, and then the top plate and heating coil.  This is repeated until a pile of the required height is formed, when steam at about 130-140 DEG  C. is applied to the heating coils and the pile is pressed.  In a modification the binder comprises an emulsion containing per litre, 30 grams of 70 per cent latex, 100 grams of 70 per cent asphalt emulsion and 1,5 grams of sulphur.
