Patent FI-991134-A (FI)
Inventor: HILTUNEN MATTI
IPC: G06F21/64
Filed: 1999-05-18
Abstract: In a method and system for authenticating locally-stored program code, a first checksum is computed using the locally-stored program code, the computed checksum is compared with a second checksum known to be valid and, if the two checksums are determined to match, the locally-stored program code is deemed valid and authentic. For increased certification reliability and dependability, before computation of the first checksum a predetermined challenge is added to the stored program code, so that the first checksum is computed from the combination of the stored program code and the challenge. This enhancement enables secure use of stored program code in applications that demand high security. Users of such software may therefore rely on the authenticity of the data processed by the software and of the data and results reported on the display of a mobile phone or keyboard throughout the entire process or transaction.

Abstract: Diesters of 2-n-propyl-n-heptanol with dicarboxylic acids, e.g. phthalic, sebacic, azelaic and adipic acids, are used as plasticizers for vinyl resins.  An example is given of the use of di(2-n-propyl-n-heptyl)-phthalate as a plasticizer for a vinyl chloride copolymer, containing over 95% of vinyl chloride, in comparison with other di-decyl phthalates and di-(2-ethyl-hexyl) phthalate.ALSO:The invention comprises diesters of 2-n-propyl-n-heptanol will dicarboxylic acids, e.g. phthalic, sebacic, azelaic and adipic acids.  The esters may be prepared by mixing the alcohol with the acid or its anhydride, preferably with heating and in the presence of an esterification catalyst.  The 2-n-propyl-n-heptanol may be prepared by subjecting n-valeraldehyde to an aldol condensation and dehydrating the aldol to 2-n-propyl-2-n-heptenal in a single stage and their catalytically hydrogenating the heptenal either in 2 stages to give successively 2-n-propyl-n-heptenal and 2-n-propyl-n-heptanol or in a single stage to give 2-n-propyl-n-heptanol directly.  The 2-n-propyl-2-n-heptanol may be produced by adding a solution of n-valeraldehyde to a hot solution of an alkaline catalyst, e.g. sodium or potassium hydroxide or an alkali metal cyanide.  In the example 2-n-propyl-n-heptanol, prepared as above, is heated with phthalic anhydride in the presence of sulphuric acid as catalyst to give the diphthalic ester.

Title: Improvements in furnaces and the like
IPC: F27B17/00
Filed: 1924-01-14
Abstract: 210,068. Puening, r. Jan. 18, 1923, [Convention date]. Heating apparatus. - In a furnace or heating apparatus of the kind described in Specification 208,170 in which a body of heating-gases is passed alternately in opposite directions through a heating-chamber the impelling member for the hot gases consists of a piston device of the oscillating- vane type. In the apparatus shown the heating- chamber 2 having a removable cover 4 is connected by side ports 10 distributed along its length with a lower chamber 8 in which the oscillating piston 16 operates. Fresh hot gases are supplied continuously by means of burners 39 delivering into the ports 10, and at each stroke of the piston a portion of the hot gases is withdrawn through ports 45, 46 leading to recuperator chambers 48, 49, and stack flues 52, 53, in which are dampers 54, 55 interconnected for operation in such manner that when the gases are passing from left to right through the heating-chamber, the right hand ports are put into communication with the corresponding stack and vice versa. The piston is mounted on a hollow shaft 15 and consists of a box-like member provided internally with perforated strengthening partitions 17 and covered externally by a layer of heat-insulating material 20. Passage of gas from one side of the piston to the other, otherwise than through the heating-chamber, is prevented by a sealing- member consisting of a curved plate 23 supported on the shaft 15 and by hook-shaped brackets 25. The air for combustion is drawn through the hollow piston by a fan and then passed through the tubes of the recuperators to the burners. The shaft 15 is oscillated from a motor through a crank arm and connecting-rod, the valves 54, 55 are operated from a disc on the shaft 15 by a friction band, a lever arm and links. In a modified construction, in which liquid fuel burners are used, two combustion chambers are provided at each side of the chamber 8, and from these upwardly flaring flues lead to the ports 10. The heating-gases may be distributed in the chamber 2 by vertical walls having perforations, which may be controlled by damper blocks. In a further modification, in which the combustion products are not brought into contact with the materials to be heated, a body of air is passed to and fro over heating-pipes and the charge. The apparatus may be used for annealing metals and glassware, the low temperature carbonization of coal, and in the cracking of hydrocarbons.

An apparatus suitable for inhalation therapy comprises an electro-acoustic transducer 12 adapted to be energized to focus a beam of ultrasonic energy near the surface of the spray liquid in a chamber 26, and a motor driven blower 50 arranged to force a current of a carrier gas into the chamber 26 so that the spray is discharged from a fitting 51 which leads to a mask. An upwardly extending arm 53 provides a trap for large droplets. The blower may be switched off so that the spray is drawn on demand by the patient. The energy is transmitted from the transducer to the spray liquid by a coupling liquid in an intermediate chamber, the two liquids being separated by a thin plastic diaphragm. The apparatus may be used to introduce contrast media into the patients lungs for X-ray etc. purposes. The blower 50 may supply oxygen or an anaesthetic gas instead of air. The spray liquid is advantageously water. The output of the apparatus may be altered by adjusting the blower or the power output of the oscillator leading to the transducer. Disinfecting-apparatus. The inhalation apparatus above is modified to produce a fog of antiseptic for room sterilization by dispensing with the coupling liquid and the mask; the acoustic energy is delivered directly into the liquid antiseptic.

Title: Improvements relating to the preparation of dough for the making of bread
IPC: A21C13/02
Filed: 1925-01-19
Abstract: 243,191. Wilson, J. E., McConnell, S., and Brown, C. Jan. 19, 1925. Bread; dough-working apparatus; proving-appliances.-In bread-making, dough is discharged directly from the mixer into each of a number of separate receptacles in which the dough is proved, the receptacles being movable to a position at which the dough is discharged to a divider or weigher. Cutting-back or braking may be effected whilst the dough is in the receptacle or on discharge therefrom. Two or more series of proving receptacles may be used and the dough may be cut back or braked in transit from one series to another. As shown in Fig. 2, the receptacles 2 are pivotally mounted in circular formation on frame 5 revoluble on ball races by bevel gearing. The receptacles are each positioned under the discharge shoot 3 of a mixer 1 and move, during the proving, to a position at which they are topped to discharge the contents into a shoot 14 having braking rollers 15 interconnected by gearing 16, 17 and driven from a pinion 18 from a belt 20 and pulleys 19, 21. The dough is received in the lower receptacles and is similarly proved, discharged and braked and passed to a shoot 24 leading to the divider. The second series of troughs need not be coaxial with the first series and may revolve in the same or the opposite direction. The braking-rollers 15 and the discharge opening of the shoot 14 may be adjustable, and the rollers may be replaced by bands or travelling bauds of plates. The receptacles may revolve about a horizontal axis, or they may be suspended from chains which are constrained to move in a suitable path. In modified forms of receptacles, Figs. 4, 6 and 8, the dough is discharged through the bottoms of the receptacles. In Fig. 4, the discharge opening is normally closed by a cone 33 operated by worm and screw gear. A revoluble scraper 39 dislodges dough from the sides of the receptacle. In Fig. 6, the receptacle 42 is revoluble to bring a kidney-shaped discharge opening 43 into line with an opening 41, a scraper 46 being provided. In Fig. 8, the receptacle is normally closed by a pivoted bottom 52 having a roller which engages a rail 55 which is interrupted to allow the door to open for discharge of the dough. A scraper 57 is rotated by a hand-wheel 58. As shown in Fig. 9, the cutting-back is effected in the receptacles by a member 61 having projecting pins 69 and vertically reciprocable by a rotary-wheel 64 having a projecting pin 63. The two methods of braking may be used in one apparatus.
