Abstract: 985,599. Ventilating vehicles. VOLKSWAGENWERK A.G. May 17, 1963 [May 25, 1962], No. 19616/63. Heading F4V. In a heating system for automobile vehicles, air is supplied by a blower and heated in heat exchangers by means of engine exhaust gases, said air being conducted into the vehicle interior in a heating conduit, characterized by the feature that at least one combustion chamber is arranged in the heating conduit for combustion of a fuel-air mixture and to act as an additional heat exchanger. In the Figure, exhaust conduits 3 and 4 from the engine 1 are enclosed by heat exchangers 5 and 6. Convection air currents from a blower 2 pass air into the heat exchanger and through heating conduits 9, 10, 11. A combustion chamber 15 is situated in the front part of the vehicle to burn a fuel-air mixture entering and leaving the same by conduits 16 and 17. Outlet ducts 12 and 13, 19 and 20, and 21 and 22 pass heated air to rear, front and defroster nozzles respectively. In a modification, there may be two heating conduits which intersect each other around the combustion chamber arid thereafter continue to the respective outlets. In this case, suitable partitioning separates the two conduits in the vicinity of the combustion chamber which is disposed at right angles to the axis of the vehicle. Air for the combustion chamber may be diverted from the heating conduit.

Abstract: 498,855. Electromagnetic relays. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. July 16, 1937, No. 19771. Convention date, April 28. [Class 38 (v)] In a polarized relay in which an armature winding builds up a flux to oppose that due to the polarizing magnet to cause the operation of the relay, the armature is made of small substantially uniform cross-sectional area so that it becomes saturated at the normal operating current, thus preventing the tendency for the permanent polarizing magnet to become reversed in polarity. As shown in Fig. 2, the magnetic circuit comprises two U-shaped magnetic yokes 6, 8 with polepieces 6a, 8a and 6b, 8b between which move the shaped ends of a pivoted armature 24. The magnetic yokes are magnetized by a pair of permanent magnets 10 having their polepieces bearing on the rear faces of the magnetic yokes 6, 8 so that like poles are produced at the ends of each yoke. The energizing windings 26 are mounted in the space between the yokes so as to surround the armature and produce a longitudinal flux therein which for one direction of current moves the armature across towards its opposite position and for a reverse direction of current maintains the armature in the same position. The armature shaft carries a series of movable spring contacts 35 ... 38 secured in a block 23a of moulded insulating-material, Fig. 5, the block 23a having a cylindrical extension 23 in which the armature is supported. The movable spring contacts operate between sets of relatively fixed contacts which are moulded into the sides of an insulating frame 1 within which the yoke member 6, 8 and other fixed parts are supported. The frame is fitted with front and rear covers, the former of which is fitted with an inspection window and the latter with spring clips adapted to hold the permanent magnets 10 in position.

Title: Improvements in electrically-driven reversing machines for regenerative ovens or the like
IPC: H02P23/24
Filed: 1950-08-15
Abstract: 683,039. Control of motors; controllers; actuation of switches. KOPPERS GES., H. Aug. 15, 1950 [Jan. 9, 1950], No. 20243/50. Classes 38 (iii) and 38 (v) [Also in Group XIII] Relates to the control of an electric motor which drives a reversing machine for regenerative ovens and the like (see Group XIII). The control gear for the motor comprises a motor-driven switch drum 11, contactors 31, 32, and a timing device 46, all housed within a container 1 which may be rendered gas-proof and partly filled with oil in order to prevent explosions due to sparking at the switch-contacts in the presence of dangerous gases. An auxiliary housing 5 has conduits for cables leading to the control gear through terminals set in a base 4. Actuation of a push-button 33 energises contactor 31 through segments 37, 40, on the switch drum which is rotated by the main motor 30 until the drum segments 38, 39, are disengaged from the associated contact-fingers. The contactor 31 is de-energised and the motor stopped so completing the poeration of closing the gas valves of the oven. A timer motor 47 is then energised through drum contacts 27, 40, and, after a predetermined period, switch 50 is closed to re-energise contactor 31 through drum contacts 53, 37. The motor 30 continues to drive the switch drum in the original direction until the drum segment 37 leaves the associated contact-finger. The operation of the reversing machine is then completed. The next operation of the machine is effected by reversal of the motor 30 through closure of contactor 32. If, through faulty operation of either contactor 31 or 32, the contact-drum is over-driven a cam operates a lever to release a safety switch and de-energise the motor. Operating means for the safety switch comprise a hollow shaft 61 which is fitted on the driving shaft 25 of the switch drum and is coupled to non- conducting discs 62, 64, having contact rods 65 therebetween. Contact-fingers are associated with the contact rods and are placed in the driving motor circuit. A spring-pressed bolt engages-disc 64, the two discs being retained in their normal position by a torsion spring 70. When a cam disc 79 is rotated due to over-running of the switch drum, one of the boss plates 75, 76, engages the bolt and the discs 62, 64, are rotated by the spring 70 so disengaging the contact fingers from rods 65 and the motor is de-energised. The safety switch may afterwards be re-set, the spring 70 being re-tensioned by means of a lever 63.

Patent GB-459878-A (GB)
Title: Polyvinyl acetal resins
IPC: C08F8/28
Filed: 1935-07-17
Abstract: Partial polyvinyl acetal resins are manufactured by bringing about the incomplete reaction of polyvinyl alcohol with an aldehyde, in the presence of an inorganic acidic substance as catalyst, under such reaction conditions that from about 2,5 to about 7, preferably 2,5 to 4, molecular proportions of polyvinyl alcohol (calculated as the monomeric substance) are caused to combine with one out: (a) by reacting an aldehyde with an aqueous solution of polyvinyl alcohol; (b) by reacting an aldehyde with a suspension of polyvinyl alcohol in a suitable solvent for the resin to be made; or preferably (c) by conducting the reaction in a liquid medium of which the composition is adjusted as the reaction proceeds so that a solid phase is never present.  In examples: (1) and (2) butyraldehyde is stirred with an aqueous solution of polyvinyl alcohol and hydrochloric acid is added; (3) n-hexaldehyde is similarly reacted; (4) various proportions of propionaldehyde are reacted with polyvinyl alcohol in aqueous hydrochloric acid solution, the equilibrium ratio of polyvinyl alcohol to aldehyde being 4 mols. to 1 in each case; (5) polyvinyl alcohol damp with methyl alcohol is dissolved in isopropyl alcohol and the solution is stirred with butyraldehyde and hydrochloric acid and then allowed to stand, whereby about 3,5 mols. of polyvinyl alcohol react with one of aldehyde; (6) as in (5) but using more aldehyde, about 2,5 mols. of polyvinyl alcohol reacting with one of aldehyde; (7) the reaction of (5) is effected in the presence of n-butyl alcohol instead of isopropyl alcohol; (8) and (9) butyraldehyde is added gradually to an aqueous solution of polyvinyl alcohol containing hydrochloric acid, and isopropyl alcohol is added as the reaction proceeds so as to prevent the formation of a precipitate; (10) butyraldehyde and hydrochloric acid, both dissolved in isopropyl alcohol, are added alternately to an aqueous solution of polyvinyl alcohol.  Other aldehydes specified are: formaldehyde and paraformaldehyde, acetaldehyde and paraldehyde, 2-ethylhexaldehyde, 3-heptaldehyde, crotonaldehyde, 2-vinylcrotonaldehyde, hexadien-2 : 4-al-1, 2 : 3-ethylpropylacrolein, 2 : 3-isobutylaryl acrolein and benzaldehyde.  Mixtures of aldehydes may also be used. Specification 351,082* is referred to.  2 : 3-Isobutylamylacrolein is obtainable by reacting hexaldehyde with isohexaldehyde.  Hexadien-2 : 4-al-1 is obtainable by condensing acetaldehyde with crotonaldehyde.

Abstract: 740,580. Lubricating systems. TRABON ENGINEERING CORPORATION. July 22, 1953, No. 20373/53. Class 12 (3). [Also in Group XXIX] The invention which consists in a flow-reversing device, is described as applied to a lubricating system, Fig. 1, comprising a reverser 13 supplied by a pump 11 with lubricant from a sump 10, the reverser controlling the flow of lubricant in a conduit 14 extending in a loop to distributer valves 16 and back to the reverser. The lubricant returned from the conduit 14 to the reverser is passed back to the sump through conduits 18, 19 The flow-reversing device comprises a housing 21, Fig. 2, containing a reverser cylinder 36 provided with a centrally disposed exhaust port 32, outlet ports 28, 29, valve ports 92a, 93a and drive ports 53a, 54a, at the ends of the cylinder, a reverser piston 41 in the cylinder being formed with openings 49, 50 for simultaneously interconnecting the outlet ports 28, 29 and the exhaust port 32 in a certain position of the piston, the housing also being provided with means associated with the valve ports and responsive to fluid flow therefrom for connecting either of the drive ports with a main inlet port 27. The means shown comprises a diverter valve 34 and a pilot valve 35. The valve 34 comprises a piston 56 in a cylinder 52, the piston being hollow to accommodate a rod 62 constituting the pilot valve 35. The rod at its ends has pistons 90, 91 adapted to operate, respectively, in cylinders 88, 89. With the parts of the reverser in the position shown in Fig. 2, lubricant flows. to inlet opening 27, through opening 60 in the piston 56 and through passage 53 to the left end of cylinder 36, and through outlet port 28 to the distributer valves of the lubricating system, some of the lubricant returning to the reverser through opening 29. The lubricant then passes through passage- 93 to act on piston 91 and move the piston and the pilot rod 62 to the left to the position shown in Fig. 4. This allows lubricant to flow from opening 27 through opening 60 in the diverter valve piston 56 and along the rod 62 to chamber 94 whereby the piston 56 moves to the right enabling lubricant from opening 27 to enter the right-hand end of cylinder 36 by way of passage 54 and move the piston 41 to the left. During the travel of the piston the position is reached as shown in Fig. 4, in which the openings 28, 32, 29 are interconnected so 'that the pressure is balanced at both ends of the loop conduit 14 in the lubricating system, any excess lubricant escaping through opening 32 to the sump. When the piston 41 reaches its extreme lefthand position the lubricant is caused to flow in the reverse direction through the loop conduit 14. Specification 689,695 is referred to.
