Title: Apparatus for integrating an electrical voltage in relation to time
IPC: G06G7/18
Filed: 1972-01-13
Abstract: 1348584 Integrating SOC BEN 13 Jan 1972 [15 Jan 1971] 1623/72 Heading G4H Apparatus for integrating the electrical voltage across terminals 5, 6 (Fig. 2) includes an integrating capacitor 1 which when charged to a predetermined level results in a relay 17 being energized to (1) displace blade 18 in an electromechanical counter and display 19, 20 and (2) close contacts 21 to short circuit the capacitor 1 to discharge it. In the embodiment of Fig. 1 (not shown) for voltages of a single polarity a voltage representing the voltage across the terminals of the capacitor (1) is applied at the output of a D.C. differential amplifier 4 having high input impedance to one input (8) of a high gain differential amplifier (9) with positive feedback, acting as a comparator. The amplifier saturates whenever the voltage at its one input (8) exceeds the reference voltage between earth and its second input (10) (derived e.g. from a diode or a voltage divider from the supply if the latter is sufficiently stable) to send a control pulse to an amplifier (15) which energizes the relay (17) to (1) drive the counter mechanism and (2) close the contacts (21) to discharge the capacitor. In the embodiment of Fig. 2 for voltages of either polarity the voltage across the integrating capacitor 1 is applied to two amplifiers 9, 9<SP>1</SP> receiving at their other inputs reference voltages 12, 12<SP>1</SP> of differing polarity. When either amplifier saturates a pulse is fed to one of two amplifiers 15 or 15<SP>1</SP> to energize relay 17 or 171 to operate blade 18 or 18<SP>1</SP> to drive the electromechanical counter positively or negatively. The integrating capacitor 1 is discharged by the closure of contacts 21 or 21<SP>1</SP>. Capacitors 25, 25<SP>1</SP> shunting the relays 17, 17<SP>1</SP> provide the power to enable blade 18 or 18<SP>1</SP> to complete its stroke after capacitor 1 has completed its discharge.

Filed: 1964-01-14
Abstract: 1,032,581. Applying container closures. IMPERIAL CHEMICAL INDUSTRIES Ltd. Dec. 14, 1964 [Jan. 14, 1964], No. 1645/64. Heading B8T. A device for inwardly depressing the top of a cap 9 before pressing its skirt into a seal fit with the rim of a container 10, comprises a support 8 and a screw 7 which forces a rigid chassis 4 downwardly to urge a plunger 2 against the cap top. The plunger slides through an annular disc 1 bearing on the cap, and when spring means 5 between the disc and chassis are fully deformed as the chassis moves down, the cap skirt is forced on to the container by the disc. In a modification, Fig. 2 (not shown), a chassis 23 has bell-cranks 21 pivoted thereto at 22, and each has a lug 24 engaging the undersurface of the cap skirt. The inner ends of the bell-cranks are pivoted on an annular member 25 urged upwardly against the chassis by spring-loaded pins 26. A plunger 28 is forced downwardly by a screw mechanism 29, to depress the cap top, and eventually this mechanism forces the annular member downwardly whereupon the lugs of the bell-cranks are released from the cap skirt which then engages the container rim.

Title: Improvements in or relating to a wear compensating device more particularly for friction brakes and similar applications
IPC: F16D65/60
Filed: 1955-01-19
Abstract: 767,453. Automatic adjustment devices. SOC. ANON. DES USINES CHAUSSON. Jan. 19, 1955 [Jan. 20, 1954], No. 1688/55. Class 103 (1). [Also in Group XXIV] In an automatic wear compensating device, particularly for friction brakes, the shaft 1, to which the cam 2 for operating the friction members of the brake is keyed, is carried in a fixed bearing 3 and is provided at its reduced diameter end la remote from the cam with a rigidly mounted sleeve 6. The sleeve 6 is provided at one end with wide notches 9 limited by teeth 10 and at the other end by an annular crown 11 provided with ratchet teeth 13 which are adapted to engage with a corresponding set of teeth on the socket 15 of the crank 16 which is adapted to be rotated in the direction #1 by fluid under pressure introduced into chamber 23 behind piston 21 in cylinder 22, or alternatively by mechanical means. An annular ring 26, fitted on sleeve 6, is formed with teeth 25 which are adapted to coact with teeth 10 on sleeve 6 under certain conditions, and is also provided with ratchet teeth 27 which coact with teeth 28 provided on toothed annular member 29 rigidly secured to bearing 3. In operation when fluid pressure is introduced into cylinder 22, the piston is moved to the left against the action of return spring 24 to the position illustrated in Fig. 2 wherein the crank 16 has been moved anti-clockwise in the direction #1 ; the sleeve 6 and consequently the shaft 1 being driven in the same rotational direction by teeth 13, 14 to rotate cam 2 and expand the friction members of the brake. For relatively light braking action, the teeth 10 do not come into contact with teeth 25 and consequently the annular ring 26 remains motionless. Should wear occur in the friction linings the teeth 10 of the sleeve 6 will move teeth 25 of ring 26 and move the latter in the same rotational direction which moves the teeth 27 with regard to the teeth 28 of the fixed toothed annular member 29, by one tooth, for example. On release of the brake, the teeth 10 after covering the whole width of notches 9 stop against the other face of the teeth 25 of ring 26 which cannot be moved due to the particular inclination of teeth 27, 28 consequently offsetting the teeth 13 with regard to the teeth 14 by an amount similar to the movement of the teeth 27 with regard to the teeth 28 in the opposite direction. This offsetting of the teeth has the effect of returning the cam 2 in an offset position with regard to its original position so that the wear of the linings is taken up.

Abstract: 992,172. Coating apparatus. R. STEIN. Jan. 18, 1963 [Feb. 15, 1962], No. 2309/63. Heading B2B. Apparatus for coating wire articles 14 with a synthetic plastic material by immersing them in a fluidized bed, said articles being continuously supplied and discharged, comprises a gate-like structure 1 which accommodates a channel 3, 3<SP>1</SP>, 3<SP>11</SP> and flue gas conduits 2, 2<SP>1</SP>, 2<SP>11</SP> for heating the air in channel 3, 3<SP>1</SP>, 3<SP>11</SP>, the gas conduits being connected at one end to a combustion chamber (not shown) and at the other end to a discharge pipe 5 connected to an exhaust fan (not shown), a fluidized bed apparatus 12 succeeded by a water tank 33 arranged at the exit of said channel and a chain 6 for conveying the articles 14 through the said channel, fluidized bed and water tank. The flue gas conduits may be arranged helically around the channel and both said conduits and channel may have extension pieces. The articles 14, suspended from bars 9 on intermittently driven chain 6, are carried through the heated channel 3, 3<SP>1</SP>, 3<SP>11</SP> and, when an article 14 reaches the fluidized bed position, the article now being within the rocking frame 20, the chain 6 is stopped and the table 13 on which the fluidized bed 12 is supported rises so that the article 14 is immersed in the bed 12 and while immersed the article 14 is rocked by frame 20. After the article 14 has been in the fluidized bed 12 for a sufficient time, the table 13 descends, the article 14 is jolted to remove excess material and conveyed by chain 6 through water tank 33 to removal station 34. When an article 14 is above bed 12, the chain 6 (driven by electric motor 7 having a variable gear and magnetic clutch 8) is stopped by a bar 9 actuating valve 10 to switch off the current to the clutch 8. Simultaneously, a roller on chain 6 actuates compressed air control valve 15 to introduce compressed air via valve 16 under piston 17, thus initiating upward movement of table 13. Table 13, on rising, actuates valve 18 to actuate piston 22 and rock the frame 20, and also actuates valve 19 which, through time relay members 29 and air reservoir 30, initiates the downward movement of table 13. Downward movement of table 13 closes valve 18, thus halting the rocking movement and then actuates valve 36, which actuates pistons 32 to give a jolt to frame 20 and shake surplus material from article 14, and then actuates valve 37 to retract pistons 32. Just before completing its downward movement, the table 13 actuates switch 38 to switch the clutch in and hence the chain 6 proceeds until the next article is in position to be coated. The rollers on bars 9 engage rails when not in the conveying channel.
