Title: Improved sewing mechanism particularly for use in the manufacture of spring upholstery
IPC: D05B11/00
Filed: 1934-10-01
Abstract: 445,197. Sewing machines. PASS, H. C., 1989, Queen Street East, Toronto, Canada. Oct. 1, 1934, No. 28015. [Class 112] A mechanism comprising a sewing-machine has two conveyer belts with two laps to grip upholstery with springs in the pockets to convey the work past the sewing-machine for sewing up the pockets, the conveyer belts and sewing-machine being in synchronism. The sewing machine 220 is of standard construction. The tensioned rubber belts 211a, 211b which convey the pocketed upholstery past the stitching devices are driven by the shaft 273 via bevelled gears, shaft 230 and chain sprockets 227, 226. The sewing-machine is driven from the shaft 230 via the sprockets 228, 229. The belts run over drums 208a, 208b. 207a, 207b. The distance between the feeding surfaces of the belts is adjusted to accommodate springs of various depths by moving a bolt 206 on the rod 203 within the limits of the slot 207, the rods 202a and 202b swinging in parallelism. Opposite the sewing- machine, the bottom lap of the belt 211b passes below a plate 214 and the top lap of the belt 211a above a plate 213. This prevents the belts from sagging and holds the pockets in a flattened form for sewing. The sewing- machine is adjustable towards or from the belt. The feed of the sewing-machine is synchronized with the speed of the belts. If the sewing-machine feed lags, an accumulated surplus of pocketed springs results. To speed up the sewing-machine temporarily to sew these, a cam 260 is brought into operation to advance the bevel gear 243 and bring a fast speed gear into action. Specification 445,196, [Group XIV], is referred to.

Patent GB-774713-A (GB)
Title: Porous materials impregnated with synthetic resin and the production thereof
IPC: C04B41/48
Filed: 1954-10-01
Abstract: Shaped bodies of graphite or carbon, are impregnated with hardenable synthetic resin in a liquid form and then submitted to the action of a gaseous hardening agent which hardens the resin without the application of heat.  The treatment may be commenced with hardening gas diluted with inert gas so as to avoid temperature increases due to the heat of reaction set up in the hardening.  After the formation of an outer shell, impermeable to liquid but permeable to gases, the gas concentration may be increased.  The diffusion may be promoted by alternate reductions and increases in the pressure of the gas.  The water forming during the hardening diffuses to the surface of the workpiece and evaporates into the treatment gas whence it may be continuously extracted.  Acid reacting gases may be employed for hardening such as halogens or hydrogen halides.  In an example, shaped graphite bodies are degassed in vacuo, impregnated with a mixture of phenol-formaldehyde resin and furfural adjusted to a viscosity of about 10CP and then allowed to dry in the air.  The articles are then exposed to the action of hydrogen chloride gas in a gassing chamber.  Other gases which may be employed are hydrogen bromide, sulphur dioxide or chlorine.

Title: Exhaust gas sensor failure detection system
IPC: G01M15/10
Filed: 1975-07-08
Abstract: 1470155 Testing exhaust gas sensors BENDIX CORP 8 July 1975 [30 Sept 1974]  28699/75 Heading G1 Exhaust gas sensors which have different electrical outputs in oxidizing and reducing gases are tested by comparing with a reference period, the time for the sensor output to fall between two levels when the gas is charged from oxidizing to reducing. The method may be used to test sensors after production or to detect a failure in use when the sensor is part of a combustion engine control system. As shown, the output of sensor 10 is fed to two comparators 16, 20, the first of which has a threshold just below the sensor output in a reducing gas and the second of which has a threshold just above the sensor output in an oxidizing gas. With a reducing gas, rich mixture, the sensor output will be high and both comparators will have low outputs. On a charge to an oxidizing gas, lean mixture, as the sensor output drops, the first threshold will be passed and the output of comparator 16 goes high charging storage capacitor 54 via diode 56. The comparator output also charges capacitor 64 of timing circuit 26. If the sensor output drops quickly enough, the threshold voltage of comparator 20 will be reached before the end of the timing period. The resulting high output at B will switch transistor 40 on, discharging capacitor 54 and, via diode 38, clamping the voltage on capacitor 64 preventing further charging. If, alternatively the timing period ends before the lower threshold is reached, transistor 52 conducts and prevents conduction of transistor 40 when, or if, the lower threshold is reached. Under this condition, capacitor 54 will not be discharged. When the voltage on capacitor 54 reaches the threshold of comparator 28, this threshold being higher than is reached in normal operation, a signal passes to a latch circuit which, if a "warmed up" signal is also present actuates an alarm. A circuit which generates an alarm for no sensor output can be made by omitting clamping diode 38.

Latitude instruments.-A stellar observation device for ascertaining or indicating approximately mean solar time comprises a celluloid disc 21 marked with diameters 25, 26 and with a peripheral scale 22. An eyelet 29 has a central aperture and is burred over to hold a celluloid arm 30 slotted at 31 and having a reading line 32. In use the device is held so that the diameter 25 is in a perpendicular plane, the disc 21 is at right angles to the line of sight and the Pole Star 33 is viewed through the central aperture. The arm 30 is then rotated until the line 32 is aligned with the ' Pointers " of Ursa Major; this gives a reading in the example shown in Fig. 1 of 1¢. Suppose this reading is taken on Aug. 8, 7“ months from Jan. 1. Then to calculate the mean solar time of the place at which the device is used, 1¢ is added to 7“, the resulting 8¥ is doubled, giving 17¢, and the latter is subtracted from 40“, giving 22¥. 12 or any multiple thereof is then subtracted to give a figure less than 12- thus 22¥ minus 12 giving 10¥, i.e. 10.45 o'clock. In the modification shown in Fig. 2 the mean solar time is indicated directly. Two scales 42, 43 divide the periphery into twenty-four for the hours and a scale 44 marks the twelve months. Suppose the device is used on April 15. The reading line 53 of an arm 51 is placed opposite April 15 on scale 44 and the device orientated as above with the line 53 in the vertical plane instead of the diameter 25 of Fig. 1. The reading edge 49 of arm 48 is then aligned with the " Pointers," the reading mark 50 in this instance giving a reading one-third the distance between 4 and 4.15, i.e. approximately 4.5 o'clock. The slots in the arms 30, 48, 51 permit of the device being closed compactly.
