Title: Improvements relating to change-speed gear clutch devices
IPC: F16D23/06
Filed: 1958-01-06
Abstract: 829,052. Friction clutches. DAIMLERBENZ A.G. Jan. 6, 1958 [Jan. 17, 1957], No. 497/58. Class 80 (2). Gears 3, 4 are selectively clutched to a shaft 5 by sliding a selector sleeve 6 either left or right from the position shown so that torque-responsive cam means 10, 11 between the hub and the shaft tend to force friction surfaces 12 in the sleeve into engagement with truncated cone friction surfaces 13 on synchronizing rings 14 axially slidable upon the hubs of the gears, cam means 18, 19 between each ring 14 and its associated gear urging the ring against the selector sleeve and baulking completion of clutch engagement until the speeds of rotations of the surfaces 12, 13 have been synchronized. The cam surfaces 10, 11, Fig. 3, are provided on teeth 8 projecting inwards and outwards from the sleeve 6 and the shaft hub. The surfaces 10 are inclined slightly to the normal through the shaft axis, and the surfaces 11 are more steeply inclined. The cam surfaces 18, 19 between the synchronizing rings 14 and the associated gears 3, 4 may be of the sinusoidal curve type, as shown in Fig. 2, and springs 16 bias the rings to their centre positions. On initiating clutch engagement by movement of the selector sleeve 6, axially parallel surfaces 9 on the teeth 8 between the sleeve and shaft hub, which are engaged in the neutral position shown, are slidden out of engagement, and the slightly inclined cam surfaces 10 engage, to obtain torque assisted axial movement of the sleeve. When one of the pairs of friction surfaces 12, 13 engage, the co-operating synchronizing ring 14 has been biased by its spring 16 to the position shown, with the proud portions of the cam surfaces 18, 19 just engaged. Transmission of torque through these cam surfaces 18, 19 opposes axial movement of the synchronizing ring 14 away from the position shown until the speeds of rotation of the sleeve and the gear have been synchronized, when the cam surfaces 18, 19 slide into full engagement with the proud portions of one lying in the dwell points of the other. The axial engaging movement of the sleeve 6 is then completed, and the more sharply inclined cam surfaces 11 on the teeth 8, 9 give an increased torque assisted axial bias to the sleeve 6 for complete clutch engagement. A ball detent 25 retains the clutch sleeve 6 in the engaged position when the torque transmitted is reduced. Wipers 21 in skewed slots 20 in the synchronizing rings 14 scrape away oil from the friction clutch surfaces 12 of the selector sleeve 6 when the associated clutch is disengaged.

Title: Means for measuring the tension in webs, tapes, films and other sheet-formed materials
IPC: G01L5/04
Filed: 1962-01-09
Abstract: 944,527. Feeding webs. ALLMANNA SVENSKA ELEKTRISKA A.B. Jan. 9, 1962 [Jan. 14, 1961], No. 758/62. Heading B6B. [Also in Division G1] The tension S 1  in the portion of a travelling web leaving the curving end of a pivoted guide plate 1 is given by S 1 .a = P.b, where P is the reaction force indicated by a force-measuring device 6 actuated by deflection of the plate 1. The tension S 2  at the other end of the plate 1 will generally be different from S 1  because of friction, but acts in a plane passing through the pivot axis 4 and so does not influence the reading P. If the tension S 1  is susceptible to variation the variation in P may be used to provide a signal to control mechanism for varying S 2  so as to maintain S 1  constant. To measure S 2 , the pivot 4 is provided in the tangential plane of the curved end of plate 1, the other end being supported by an arm pivotable on the pivot 4. Instead of pivots, plate 1 may be mounted on flexible steel bands or rubber bushings.

Patent GB-191000510-A (GB)
IPC: G09F9/37
Abstract: 510. Connor, L., and Wilkinson, W. Jan. 8. No Patent granted (Sealing fee not paid.) Monogrammic signs and signals.-Words and numbers are built up from a field of pivoted elements situated behind apertures in the front of a casing and arranged to be rocked in groups. Electro-magnetic actuating and selecting devices are provided, including a distributor which puts the sections of the indicator successively under control of a keyboard, so that an announcement can be written down as on a typewriter. The inside of the casing may be illuminated, and each element may consist of a transparent or translucent ball, cup, or lens, Fig. 3, with an opaque portion 2b normally blocking the aperture 7, or of a rocking transparent cup with a folding-blind attachment. Or the elements may consist of complete spheres or cylinders, solid or hollow, and optionally filled with liquid. External illumination may be employed, the rocking balls &c. being adapted to reflect light from part of their surfaces. For daylight use, the balls are coloured. The rocking-motion of each element on its pivot 6, Fig. 3, is effected through connexions 8, 9, 13 by the core 15 of a pair of solenoids 16, 17, which effect the forward and return motions respectively. The indicator field is divided into sections C, Fig. 1, each consisting of thirty-five elements, the " forward " solenoids 16 of which are connected to a transverse row of thirty-five contacts 27 on a board 28. There is a row of contacts 27 for each of the sections C, and, when operations are commenced, the contacts 27 of the first of the sections C are engaged by a row of contacts 37 on a non-conductive band 34. Each contact 37 is connected, through a metal strip running lengthways in the band, with a fixed contact 39 on which the metal strip presses. If now a key, such as 42, is depressed, a circuit is completed from battery 31 through a number of leads 40 connected with certain of the contacts 39 and through the corresponding contacts 27 of the first section C, and a character or numeral corresponding to the key depressed appears in this section. The return motion of the key 42 closes the circuit of a solenoid 47, which, by means of a pawl 45, advances the band 34 and brings the contacts 37 into engagement with the second row of contacts 27. The effect of depressing a second key is therefore to display a character in the second section C, and so on. The distributor may be operated non-automatically. A spacing-key is provided, and also a key for wiping-out an existing inscription by energizing all the " return" solenoids 17. Wiping-out is also effected automatically by contacts 51 when the contacts 37 have passed the last row of contacts 27. When it is only required to display a numeral, for instance, in calling carriages, each section U may have a separate series of switches numbered from 0 to 9, and each switch is preferably adapted to wipe out the numeral previously shown.

Title: Power supply circuit
Inventor: PLAGGE JOSEPH A M
IPC: H02M3/156
Filed: 1994-04-14
Abstract: For charging a battery (6) a self-oscillating power supply circuit is used in which energy is stored in a transformed (Tr) during the  so-called forward intervals, which energy is applied in the form of a charge current to the battery (6) during the so-called flyback intervals. To prevent overcharge of the battery (6), the circuit is provided with an acculmulator voltage protection circuit (10) receiving its power supply from the battery (6), to which circuit a fraction of the battery voltage is applied by means of a voltage divider (R3, R4) which is arranged across the battery (6) by means of a switch (S1) during the flyback intervals. To prevent the voltage drop accross the internal resistance of the battery from influencing the measurement of the battery voltage, the battery voltage is measured after the end of a flyback interval and before the commencement of the next forward interval. To this end the inputs (11, 12) of the accumulator voltage protection circuit (10) are short-circuited with the aid of two diodes (D1, D2) during the flyback intervals.

Title: Manufacture of sheet heater unit
Inventor: HIGASHIYAMA KENJI
IPC: H05B3/20
Filed: 1996-01-05
Abstract: PROBLEM TO BE SOLVED: To obtain a sheet heater unit having a positive resistancetemperature characteristic with excellent safety, by specifying the mixture material, and the coating and the baking conditions. SOLUTION: At first, a carbon powder a metal membrane is coated, and a silicon resin are mixed with an organic solvent. The resultant mixture is coated on at least a pair of electrodes formed on the surface of a heat resisting insulating base making a part of the electrodes is superposed, so as to form a coat for heating. Then, it is baked at 250 to 450 deg.C. As a result, since the substance coating a metal indicating the positive resistance-temperature characteristic, on the carbon powder indicating the negative resistance-temperature characteristic essentially, is used to the conductive particles, the electric resistance is smaller in the coating metal film side, and the majority of current flows to this side.  Consequently, the resistance-temperature characteristic indicates the positive property by showing the characteristic of the metal film mainly, and it can be used as a safe heater unit generating no abnormal heating.

IPC: H02M3/155
Filed: 1999-01-04
Abstract: PROBLEM TO BE SOLVED: To provide a power supply equipment which can be operated stably even at light load. SOLUTION: A power supply equipment 10 is so structured that the voltage at which a capacitor 126 for a power supply is charged may be applied to a gate terminal of a switching element 120 to turn the element 120 into a conducting state. When the switching element 120 is turned from a conducting state to a cut-off state and then induced current is allowed to flow through a retifying element 124 by the energy accumulated in an inductance element 130, the capacitor 126 is charged from a power supply Vint. In this power supply equipment 10, at a specified period of time after the switching element 120 is cut off, a switching element 44 conducts for a specified period of time to charge the capacitor 126 from the power supply Vint. Because of this structure, the capacitor 126 can be surely charged even at light load in which induced current disappears in a short time.

Filed: 1998-01-05
Abstract: PROBLEM TO BE SOLVED: To reduce unpleasant feeling to a driver and a passenger due to the noise of a cooling fan in relation to a battery cooling device to cool the battery by means of the air inside the vehicle. SOLUTION: Since a cooling fan 3 is arranged at more downstream side of a cooling air flow than a secondary battery 2, the secondary battery 2 functions as a sound insulation material and the noise at the cooling fan 3 is hardly heard inside the vehicle. As a result, unpleasant feeling and a sense of incompatibility to a driver and a passenger can be reduced and restrained. In addition, the cooling fan 3 is arranged at the side opposite to a space A inside the vehicle with respect to the secondary battery 2, that is, the secondary battery 2 is arranged in between the cooling fan 3 and the space A inside the vehicle, so that the secondary battery 2 functions as a sound insulation wall. Whereby, the noise at the cooling fan 3 is hardly heard by the driver or the passenger and the unpleasant feeling to them is further reduced as well.
