Inventor: KURZ ARTHUR
IPC: G11B7/09
Filed: 1988-09-30
Abstract: Apparatus for the reproduction of data which can be read contactlessly from a recording medium by means of an optical scanning device. Such apparatuses are equipped with a focus control circuit, in order to focus the light beam scanning the data onto the recording medium, and with a track control circuit, in order to be able to guide the light beam on the data tracks. However, the control amplifier (FR) of the focus control circuit is affected by an off-set voltage, which varies with the temperature and ageing of the control amplifier. In order to compensate automatically for the off-set voltage of the control amplifier (FR) of the focus control circuit, an input of the control amplifier (FR) is fed an off-set compensation voltage, which is varied until the high-frequency components of the focus error signal (FE) assume a minimum, since in this case the off-set voltage is optimally compensated.

Abstract: 1477803 Feeding pipes K L LAUTERJUNG and K HOFFMAN 17 Jan 1975 [19 Jan 1974] 2175/75 Heading A5R A feeding pipe 1 to be inserted into the gastro-intestinal tract of a body to be fed is provided at its leading end with a balloon 2 which can contain liquid to act as a weight to assist in the insertion of the pipe, the device being so arranged that the liquid may be discharged from the balloon into the body after the insertion has been completed. In a first embodiment Fig. 1 this is achieved by means of sets of self-closing slit valves V1, V2. The valves V2 open on application of suction to the interior of the tube and allow the liquid to drain out of the balloon into the tube interior. The valves V1 open on application of pressure to the interior of the tube and allow discharge of the liquid into the body and also passage of liquid food. In a second embodiment, Fig. 5, the balloon terminates in a discharge nozzle 15 with openings 16 which are arranged, during insertion of the pipe, to be sealed in a pocket 17 in the outer surface of the balloon. This pocket may be formed by forcing part of the balloon wall into the leading end of the pipe. Either of the feeding pipes described may be used with a pump (Fig. 7 not shown) which may incorporate rollers which succesively roll along and squeeze the pipe to force the nutrient along the pipe.

Abstract: A process for the continuous pasteurisation of eggs characterised in that liquid egg material is passed under a superatmospheric operating pressure through a first scraped surface heat exchanger to raise the temperature of the egg material to the pasteurisation temperature after which it is passed to a heated holding vessel under pressure of a sterile inert gas for a period of time which ensures pasteurisation but which is sufficiently short to ensure that substantially no coagulation occurs, and finally through a second scraped surface heat exchanger where it is cooled to a temperature below 10°C over a period of time less than 5 minutes.

Abstract: The invention relates to air-drying and finishing coats for wood for exterior and interior finishes, comprising the so-called nonvolatile matter, which represents an intimate mixture of modified natural oils, pigments, extenders and small proportions of varnish additives, and a low-boiling petroleum hydrocarbon, which is suitable as a solvent and is present in an amount of </=15% by weight, based on the total amount. An air-drying stain for exterior finishes is to be provided, with which a spotty or mottled appearance of the dried surface is avoided reliably even after a single coat of paint. This objective is accomplished by a stain, the mixture of chemically modified natural oils of which have a consistency, so that the efflux time from a DIN 53,211 4 mm viscosity cup is between 28 and 35 seconds, and the extender of which comprises a fine, cryptocrystalline, amorphous silicon dioxide, in which the proportion of particles with a particle size less than 40  mu m is greater than 95%.

Abstract: An improved system for performing an alkylation process and a method for handling liquid catalyst in an alkylation process. This improvement involves a method and apparatus by which liquid alkylation catalyst contained in alkylation process equipment can be safely stored and isolated from the external environment. Additionally, the apparatus improvement will allow for an improved method for controlling the circulation of liquid alkylation catalyst by providing means for quickly stopping the circulation of alkylation catalyst. The apparatus improvement comprises a baffle (20) contained within a vessel (10) which is attached to the bottom (33) of the vessel and extends upwardly into the vessel. The baffle is designed to allow for the liquid flow between the inside of the vessel and the inside of the baffle and it allows for the venting into a vapor space from the top of the baffle (24). Within the baffle is standpipe (32) which provides for fluid flow from within the baffle to a region outside the vessel. <IMAGE>

Abstract: 136,338. Blackstone, G. M., Carter, F., and Carter, E. Jan. 17, 1919. Starting.-In un engine of the kind in which fuel is pumped in governed quantities for each charge and is injected at or near the end of the compression stroke, the cam shaft can be placed in four different positions, in which (1) the engine is at rest, (2) it starts as a single-acting compressed-air engine, (3) it works as a four-stroke internal-combustion engine on half-compression, and (4) it works on full compression. Positions (2) to (4) may be duplicated for starting in the reverse direction. Fig. 1 shows the part of the cam shaft a for actuating the valves of one cylinder, and indicates the axial positions of the cam bowis b for the exhaust valve, c for the starting-air valve, d for the fuel-sprayer valve, and e for the working-air valve. The cam shaft is shown in the neutral position, and may be moved axially to the three successive positions indicated by broken lines f<1>, f<2>, f<3> for starting, and to the positions f<4>, f<5>, f<6> for starting in the reverse direction. In position f<1>, the starting-air valve is actuated on every out-stroke by the cam c<1>, and the exhaust valve during the whole of each in-stroke by the cam b<1> and the sloping end of the cam b'. In position f<2>, the working-air valve is actuated every alternate out-stroke by the sloping end of the cam c<1>, the fuel valve by the cam d<1>, and the exhaust valve by the cam b<3> during each alternate instroke, and by the half-compression cam b<5> during the first part of each compression stroke. In position f<3>, the half-compression cam ceases to act, and the working-air valve is actuated from the outer face of the cam e<1>. The axial movement of the cam shaft is effected by a handle j moving over a notched plate j<3>, Fig. 5, and mounted on a plug j<1> carrying an eccentric member j<2> engaging a slot k<1> in the plunger k, which is guided by a pin k<2> entering a keyway in the plunger. The cam shaft a rotates in the plunger and is moved axially by a shoulder. The cam shaft is driven by skew gears l, l<1>, so that the axial movement is accompanied by an angular one in order to ensure the proper position of the cams for starting and running. The compressed air for starting is supplied by a pump driven by the engine and connected to a container by a pipe having branches to the starting-valves. If the container pressure is too low for spraying, the compressor may be shut off from the starting-valves and container to enable sufficient pressure to accumulate for injection when the cam shaft is in the half-compression position.
