Title: Automatic location of a vehicle in a railway train which has  no answering unit or whose answering unit fails to answer
IPC: B61L1/16
Filed: 1971-04-19
Abstract: 1341258 Interrogation systems SIEMENS AG 19 April 1971 [14 April 1970] 27309/71 Heading B7N In an interrogation system for identifying passing railway vehicles, axle counting means are provided for locating vehicles which do not carry an answering unit or on which the answering unit is inoperative. The answering unit is positioned between the two inner axles on vehicles having an even number of axles and above the middle axle on vehicles having an odd number of axles and the answering signal from the unit when interrogated includes, in addition to the coded vehicle number, a representation of the number of axles on the vehicle. The code signals 31 from the interrogator are passed via inhibitor 32, which ensures that only signals from vehicles passing in a set direction are processed, to a buffer store from which the information concerning the number of axles is supplied to a switching unit 39, to an adder 42, and also to operate a switch 43. The switching unit, when the axle number is even, feeds half this number to counter 41 and opens gate 37 so that the axle pulses on conductor 34, all of which are counted by adder 36, can be supplied during the passage of the latter half of the vehicle to counter 41 to count this back to zero. When the axle number is odd switching unit 39 supplies the next integer smaller than the half value to the counter 41 and by gate 37 blocks the first counting pulse corresponding to the middle axle. In each case when the counter 41 returns to zero comparator 46 is energized to compare the count in adder 42, giving the signalled number of axles, and that in adder 36 giving the actual number of axles and when these agree signal D is issued to initiate print out of the vehicle number FK and the signalled and actual number of axles SMA and SEA. When a unit is not present on a vehicle or is inoperative the circuit arrangement is not operated apart from the axle count to adder 36 and when the next vehicle carrying an operative unit passes the process up to the operation of the comparator is repeated and this on detecting the difference feeds pulses to the adder 42 until the numbers agree. The number of pulses is counted by unit 47 and is printed out as FMA when signal D is issued by the comparator.

Title: Improved apparatus for converting tidal energy into mechanical or electrical power
IPC: F03B13/26
Filed: 1919-11-07
Abstract: 158,661. Woodhead, L. W. Nov. 7, 1919. No Patent granted (Sealing fee not paid). Tidal energy, utilizing.-A sea wall is constructed with one or more pairs of apertures 2 extending through it from side to side, each end being fitted with sluice valves 12 to control the flow of water to turbines 5 or the like fitted between the apertures. The turbines 5 are each mounted on a vertical shaft 7 supported in bearings 6. 8 and carrying a dome-shaped driving- pinion 10, shown in plan in Fig. 11. The valves 12 move in vertical guides and are raised and lowered by cords 14 which pass over pulleys 15 on brackets 17, and are connected to horizontal rods extending along the top of the wall to a central control station. The turbines are arranged in groups of, say, sixteen, each group driving a dynamo. The driving-wheels 10 are connected by chain gearing running in an oil bath shown in Fig. 11. The down-turned edges of the wheels 10 run in circular baths 57, while the chains run in straight channels 58, round the end wheels 10, and tangentially to the intermediate wheels. Apparatus for electrically controlling the sluice valves in accordance with the ebb and flow of the tide is shown dia. grammatically in Fig. 9. The water flowing through a passage 47 in the wall 33 from left to right moves a paddle 32 into the position shown, making a contact 35, 39, energizing a magnet 30 shown on the left-hand side of Fig. 9, and operating a switch 27. The motor 25 then, by means of the worm-wheels 24 and screwed sleeves 22, raises the rods 20 and the sluice valves attached to them. One of the rods 20 has an abutment 50 which lifts the tank 41 on a conduit 43, so that the water in the tank 41 runs into the tank 42, the fall of which causes the rod 46 attached to the lever 44 to draw over the spring arm 37 and to close the contact 36, 40. This causes the magnet 30 to operate the switch 28a controlling the motor 26, which, by means of the corresponding wormwheels 24, operates the rods 21 and opens the other pair of sluice valves. With all the valves open, the flow of water ceases, the springs 48 centralize the paddle 32, and the contact 34, 38 is made, energizing the magnet 30 which controls the switch 29. This excites both motors 25, 26, driving them reversely so as to close all the valves. The part 38 is moved out of contact with the part 34 by an insulated rod.

Title: Improvements relating to internal combustion engine fuel pump driving arrangements
IPC: F02M37/08
Filed: 1950-11-10
Abstract: 716,367. Driving fuel pumps. DAIMLERBENZ AKT.-GES. Nov. 10, 1950 [Nov. 10, 1949], No. 27574/52. Class 102 (1). [Also in Group XXVII] In an internal-combustion engine fuel pump driving arrangement, provision is made for the driving of the pump on the one hand by an electric motor and on the other hand by a driving member driven by the internal combustion engine, such provision including clutch means which permits of the connection of the pump alternatively to either one of the drives and its disconnection from the other. In Fig. 1 a fuel pump 2 is driven either by an electric motor 8 or by the engine which it supplies, according to the position of a clutch 11. When the engine is at rest absence of pressure in a pipe 24 fed by a pump 25 e.g., by the lubricating oil pump, driven by the engine enables a piston 14 to move to the left and shift the clutch into a position in which the electric motor drives the pump. Thus on closing a switch 34 which may or may not at the same time also switch on the ignition current or set the starter in operation a detent 32 frees a rod 30 which. moves to the left and closes a switch 9 which sets the electric motor in operation. When the engine is running the pressure in the pipe 24 raises a control valve 19 and then passes to a space 16 and shifts the clutch by means of a lever 13 into a position in which the pump is connected to a gear 12 driven by the engine. At the same time a projection 36 on the clutch lever 13 returns the switch to its open position. A restriction 28 may be regulable. In Fig. 2 both the engine and the electric motor drive the pump through the medium of a one way clutch 37, 38. The electric motor is switched on by means of a lever 41 either operated, conjointly with the engine starter or at will by the operator. Provided the lever 41 is returned to the inoperative position, the electric motor switch is opened either by a thermosensitive device 43 for example in the oil circuit which may act through a servomotor. or by a piston operated by pressure liquid for example by oil from the engine lubricating oil circuit. It is stated that the electric motor may be cut out by means responsive to engine speed. A delay action device may be provided to delay operation of the means for cutting out the electric motor. A changeover clutch for changing over from electric motor drive to engine drive may be controlled by hand. The electric motor may be switched in when the ignition switch or the engine starting switch is operated and is cut out automatically when the engine has developed a normal running condition.

Title: Process of manufacturing emissive electrodes for electric discharge apparatus
IPC: H01J9/04
Filed: 1945-10-22
Abstract: 610,535. Cathode materials and processing. SOC. ANON. POUR LES APPLICATIONS DE L'ELECTRICITE ET DES GAZ RARES ETABLISSEMENTS CLAUDE-PAZ & SILVA. Oct. 22, 1945, No. 27793. Convention date, Jan. 15, 1942. [Class 39 (i)] An electrode of an electric discharge tube, e.g. a discharge lamp; is provided with an emissive coating of a substance having the composition of Ba(OH)2 plus between 1 and 1.1 molecules of water, preferably 1.03-1.07 molecules of water, and when depositing the coating the presence of additional water or water vapour is avoided, subsequent processing including the reduction of the hydroxide to oxide, taking place inside the discharge tube. The substance which is a solid powder at room temperature is made either by decomposing the octohydrate or by hydrating the anhydrous hydroxide. In coating a filament, the filament and its supporting stem are enclosed in a glass globe through which a current of nitrogen is passed, and a shaft carrying a cup filled with emissive substance is moved upwardly into contact with the filament and rotated so as to coat it; the shaft is then lowered and a current passed through the filament to melt the emissive substance. This operation may be repeated several times. Alternatively, the coating may be melted before being applied by pasting, painting or immersion. The coated filament may then be temporarily coated with paraffin to prevent oxidation by the air. During subsequent processing the electrode is inserted inside the discharge tube, the latter is exhausted, and a temporary gaseous atmosphere is introduced, and a discharge of increasing intensity is passed so as to " form " the electrode; the gaseous atmosphere is then removed, and mercury vapour-the final filling-is introduced. The invention may be applied to luminous discharge tubes containing rare gases or mercury and coated with luminescent material, which can be used in signs, letters or designs, and to highpressure mercury vapour tubes generating ultra-violet radiations. Specification 554,958 is referred to. The Specification as open to inspection under Sect. 91 describes a similar coating compound in which barium is replaced by strontium, and refers to mixtures of the barium and strontium compounds. This subject-matter does not appear in the accepted Specification.
