Title: A voltmeter to measure and verify the condition of charge of accumulator batteries for automobiles or other purposes
IPC: G01R31/36
Filed: 1931-05-05
Abstract: 372,554. Current and pressure meters. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Ateliers Da et Dutilh; 81, Rue St-Maur, Paris.) May 5, 1931, No. 13314. [ A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 28, 1931.] [Class 37.] In order to determine the state of charge of accumulators for motor vehicles, a voltmeter is connected across the starting motor so as to measure the voltage of the accumulator when supplying a heavy current, the voltmeter having two scales, of which one is constantly visible and the other only appears temporarily to indicate the voltage when the accumulator is on load. As shown in Fig. 2, the accumulator 1 is connected at one pole to the chassis m of the vehicle and supplies the headlamps &c. 3 through a switch 4 and the starting-motor 6 through a switch 5. A voltmeter 7 is connected across the terminals of the starter 6 either permanently or, as shown, through a two-way pushbutton switch 8 by which it may be connected either across the starter 6 or across the accumulator 1 to enable the voltage on open circuit to be read. A lamp 10 may be connected in parallel with the voltmeter to illuminate the dial or the index, or the dial and index may be coated with radio-active material. As shown in Fig. 3, the voltmeter is of the moving-iron type, the coil 14 of which is connected at one end to the casing 11, and thus to the body of the car, and at the other end to a terminal 12. A lamp 10 is arranged opposite an opening 19 in the casing and is of the type having a cap at each end, these caps engaging spring terminals of which one is insulated and the other connected to the casing. The dial 18 is of transparent material having on its front face the usual scale of volts, as shown in full lines in Fig. 5, the pointer 20 moving in front of this scale. On its back, the dial 18 carries a supplementary scale marked to indicate the state of charge of the accumulator, this scale only being visible when the lamp 10 is illuminated by closing the starter switch 5. Alternatively the auxiliary scale may be marked on a transparent dial behind the dial 18, on to which it is projected when the lamp 10 is illuminated. In the construction shown in Fig. 7, the auxiliary scale is marked on a segment 22 which is moved in front of an aperture 21 by means of a plunger 27 drawn into a coil 28 which is connected in place of the lamp 10 or in series with the starter 6. Alternatively as shown in Fig. 8, the auxiliary scale 22 may be moved into position mechanically by means of a wire 31 attached to the starting pedal 33.

Title: Electron discharge devices
IPC: H01J25/34
Filed: 1949-05-19
Abstract: 691,900. Velocity-modulated tubes. KOMPFNER, R., and BUCKINGHAM, J. Nov. 13, 1950 [May 19; 1949], No. 13374/49. Class 39(i) In an amplifier comprising an evacuated waveguide structure 2 traversed by an electron beam directed transversly or inclined to the direction of wave propagation therein, interaction regions separated by drift spaces are formed by localized concentrations of the electric field in such a way that the electrons experience substantially the same phase conditions at all the local concentrations, the electron beam thereby becoming bunched and thereafter delivering energy continuously to the wave at each interaction region. The structure 2 consists of an array of parallel metal or dielectric strips, Fig. 2, the spacing apart r of which is less than half the spacing s in the direction of electron travel. The thickness b of the strips is as small as practicable to allow maximum beam current to pass between them. The electrons from the cathode 1 are focused, as by a magnetic field H. Input and output waveguides 5, 6 are coupled to the amplifier by horns 7, 10, and artificial or natural dielectric lenses 8, 9, the output lens and horn being tilted if necessary, to allow for tilting of the wave fronts caused by the interaction with the electron stream. The output may be taken from a second waveguide structure within the envelope but spaced from the first structure 2 by a drift space, the performance of this tube being analogous to that of a klystron. The structure 2 may be made resonant by enclosing it in a metal casing, Fig. 3 (not shown), such that the walls of the casing are n #/2 apart and are provided with narrow slots for coupling with the unloaded space outside. Such a device acts as a self-oscillator. The electrode 3 serves as a collector, alternatively it has a negative bias and reflects the electron beam back through the structure or structures.

Title: An improved electro-pneumatic control for priming syphon systems
Filed: 1939-05-06
Abstract: 528,415. Siphons. INCANDESCENT HEAT CO., Ltd., and HAVERLEY, R. W. May 6, 1939, No. 13566. [Class 69 (i)] A siphon for use with solutions of high freezing point, corrosive fluids &c. comprises a dual-acting pneumatically operated reciprocating control for the delivery valve, and another dual-acting control associated with an electric circuit governing the operation of the system, the make and break of the electric circuit being controlled by members located in said circuit and associated with the siphon system. The siphon 3 communicates with an air chamber 7 containing an electrode 8 and provided with a relief valve 10 and a valve 11a leading through pipe 11 to a vacuum pump 12 driven by a motor 13 ; the delivery side of the pump leads through pipe 14, with relief valve 14a, to a valve chamber 15 with valve 16 controlling a piston 6c connected through stem 6a to an outlet valve 6 on the siphon. On pressing a starter push-button 19, a solenoid 17 closes a switch 18 and the motor 13 is driven, the pump 12 evacuating the siphon and delivering air past valve 16 to lift piston 6c and hold the valve 6 closed. When the liquid rises to the electrode 8, a solenoid 9 raises the valve 16 and the air is delivered above the piston 6c to open the valve 6 ; as the valve 16 opens, a pawl 6b breaks a contact 20 to deenergize the solenoid 17 and open the switch 18. A stop press-button 21 enables the circuit to be broken at any time. In another form, the electrode 8 is replaced by a float controlling the operation.

Title: Colour correction selector
IPC: H04N1/62
Filed: 1955-05-11
Abstract: 799,492. Copying by scanning. ADALIA, Ltd. May 11, 1955 [May 11, 1954], No. 13651/55. Class 40 (3). A coloured picture 1 is scanned by a flying spot scanner 30 and reflections of the blue, red and green components are picked up by the corresponding photo-cells 35b, 35r and 35g giving signals bo, go and ro fed to respective amplifiers 10b, 10g, 10r. The outputs of these amplifiers are fed through computers 9 and 46 to the C.R. tubes 47m, 47c, 47j and 47n which produce the magenta cyan yellow and black plates 49 from which a coloured print may be made in the conventional way. The gain of the amplifiers 10 is controlled by signals from photo-cells 38b, 38g and 38r which pick up reflections from three plane plates 11b, 11g and 11r of grey paper when these are scanned by the C.R. tube 31. Thus to vary the signal fed to the computers 9 and 46 for any particular component colour it is merely necessary to shade the appropriate plate 11 either with a white crayon to increase the reflection or a black one to reduce it, thus producing in the printing plates 49 the desired colour changes. To enable an operator to judge the effect of alterations to the plates 11 before the printing plates 49 are made switch 45 is opened and the signals from the computer 9 are fed to a further computer 39 which produces signals bi, gi and ri which are then fed to the grids of C.R. tubes 5b, 5g and 5r to control the spot intensities of these tubes. The spots from these tubes are imaged by lenses 6 on to a screen 8 in exact register so that the picture produced thereon forms a convenient means of checking the alterations made to the plates 11. Light bulbs 42 and diffusers 40 and 41 simultate normal viewing conditions of the finished reproduction. An arrangement is described using iconoscopes instead of C.R. tubes 30, 31. The original 1 may also be scanned using orthicons and a beamsplitting device. Specification 799,491 is referred to.

Title: Improvements in or relating to textile combing machines
IPC: D01G19/14
Filed: 1942-10-30
Abstract: 563,282. Combing machines. NASMITH, G W., NASMITH, J. I., and DISTRICT BANK, Ltd. [Legal representatives of Nasmith, J. W.]. Oct. 30, 1942, Nos. 13753/42 and 18006/43. [Class 120 (i)] In order to increase the production of a Nasmith combing machine the use of the usual combing cylinder segment S is dispensed with and a guide plate 9 is fitted to rise and fall in a path between the detaching rollers D, d<1>, which rotate in fixed bearings, and the combing cylinder cover V and is synchronized in its movements with those of the rollers, nipper and top comb so that it engages, guides and controls in both directions an end of the fleece backed off for piecing ; the plate rises to its uppermost position to receive the end of the fleece as it begins to be backed off, descends with the fleece, then rises therewith and dwells during the rise until the top comb N<2> has commenced to withdraw, and finally resumes its uppermost position. As shown, the cylinder cover V is carried upward for protection against injury by the needle segment N and a pair of arms 5, pivotally mounted on the cylinder shaft and joined at their ends by the arcuate guide plate 9, are connected by rods 6 to levers 7 fixed on a rocking-shaft 8. The shaft 8 is actuated so that, as the detaching rollers D, d commence to back-off, or return a length of the previously detached fleece F for piecing, the tips of the fibres are directed to the guide plate 9 which moves downwards carrying the end of the fleece with it until the rollers reverse their rotation when the plate rises with returning fleece ; when the roller movement is nearly at an end, the roller-driving mechanism is disengaged, and during the slight dwell, before the rollers are again driven, the plate momentarily stops to allow the withdrawal of the retreating nipper N<1> and top comb N<2> and then follows them as the tuft held in the nippers is presented to the cylinder needles. To prevent any tendency for the tips of the fleece to follow around the surface of the roller D during backing-off, a flexible leather curtain 11 is secured at one end to a sector 14, pivoted freely on the shaft 8, and at the other end to projections 5a on the arm 5, and passes over a roller 10 mounted in an adjustable bearing so that, with the contiguous surfaces of the curtain and roller D always moving in opposite directions, any fibres tending to follow the roller are taken by the curtain downwards. The curtain is kept taut by a spring 15 and the roller 10 can be adjusted so that the curtain clears both of the rollers D, d. In a modification, the guide plate has its concave side directed towards the detaching rollers and is carried by arms pivoted on a fixed pin disposed beyond the roller d and oscillated by a rod and lever from the shaft 8 ; in this form the plate may act as a stripper for the roller d<1> and a cleaner roller may be disposed below and between the rollers D, d. Specification 489,003 is referred to.

Abstract: 1,261,323. Thermocopying machines. MEMOFAX AS. March 20, 1970 [March 24, 1969], No.13794/70. Heading G2A. In a thermocopying machine in which the copy sheet is carried on an endless belt past a rodshaped heater disposed opposite a curved portion of the belt, the copy sheet is retained on the belt by pressure means which can be adjusted as desired. In the form shown, a belt 1 passes over pairs of rollers 2, 3, the heater 6 and reflector 7 providing a narrow band of infrared rays across the copy sheet as it passes round rollers 2. A rubber support pad 4 is secured to the belt. A base sheet 26 lies over pad 4, and its rear edge is secured to a rail 25 on the underside of the belt by means of screws passing through a rail 23 within an end loop of sheet 26. The original 27 and copy sheet 28 are laid on sheet 26 and covered with a top sheet 5. The rear edge of sheet 5 is looped so as to hold a rail 19 having a number of hooks 20. These engage through holes in belt 4 with corresponding holes in a rail 22 on the underside of the belt, so attaching the rear edge of sheet 5 securely to the belt. The front edge of sheet 5 is secured between two rails 8 and 9 by screws 10. Rail 9 is attached to a strip 12 looped round a rail 13, the rail being connected by a Bowden cable 17. The cable passes through holes in V springs 15, 16 carried by an angle iron bar 14 and on its free end is a sleeve 18 which can be secured in various positions along the cable by a screw. Thus the tension is applied to cover sheet 5 and hence the contact pressure between the original and copy sheets can be varied by adjusting the position of the sleeve 18. As the sheets 27, 28 pass round rollers 2 through the heating station, the tension on cover sheet 5 will increase, and the contact pressure further increase. This pressure may be still further increased by the provision of a counter-pressure roller (29), Fig, 5 (not shown).

Abstract: 422,528. Bridges; gratings. IRVING, W. E., Maple Avenue, Glenbrook, Connecticut, U.S.A. May 8, 1934, No. 13872. Convention date, May 10, 1933. [Classes 20 (i) and 107] The deck or floor of a highway bridge consists of an open-mesh grating, which rests directly at points distributed over its area on a skeleton supporting structure 7, 8, and comprises metal strips 5, 6 set on edge with their upper edges in the same plane to form a traffic surface in which the total area of the openings exceeds the total area of the upper edges of the strips. The supporting structure com - prises sills 7 and stringers 8 as shown in Fig. 3. The grating is formed of a plurality of parallel straight strips 5, between which bent strips 6 are riveted or otherwise secured, as shown in Fig. 4. The strips 5 are spaced about 2¢ inches apart, and successive rivets in each strip 5 for securing the bent strips 6 are spaced about 5 inches apart. The openmesh flooring is applied both to the fixed portions 1 of the bridge and to the bascule or lifting portions 2. To provide a footway for animals, a filling of cement 4 may be arranged as shown in Fig. 2. The invention may also be applied to bridges of the verticallift type. The grating is substantially continuous and integral in character from side to side of the bridge and along the entire length of considerable sections thereof, and is preferably formed by connecting together large grating sections by spliced joints as described in Specification 270,567, [Class 107]. Specification 330,186, [Class 107], also is referred to.
