Title: Improvements in or relating to automatic temperature controlled ovens
IPC: G05D23/24
Filed: 1953-12-16
Abstract: 775,176. Automatic temperature control systems. GENERAL ELECTRIC CO., Ltd., ASTON, S. G. G., and JOHNSON, M. P. Dec. 16, 1954 [Dec. 16, 1953], No. 35072/53. Class 38 (4). [Also in Group XI] In a temperature control system for a crystal oven, wherein electric oven heaters are energized through a magnetic amplifier controlled in accordance with the oven temperature, positive feed-back for the amplifier is derived from the load circuit for improving the response of the system. A cylindrical crystal oven (not shown) is wound with main heating coils 27, 28 and carries a block which contains thermistors 42, the latter being placed in close proximity to subsidiary heaters 20 for rapid attainment of the oven temperature. Heaters 20, 27, 28 are energized in series with positive feed-back windings 33 of the magnetic amplifier from a rectifier 36 supplied from an A.C. source 38 in series with the load windings 30 of the amplifier. The thermistors 42 are connected with fixed resistors 43 in a D.C. bridge circuit 41, whose output to the control windings 32 of the amplifier is zero when the oven temperature reaches a datum value set by resistors 43. Amplifier windings 34 are energized from a separate D.C. source 39 for biasing the amplifier core 31, so that the impedance of load windings 30 is effectively infinite when the bridge is balanced, i.e. no current flows in heaters 20, 27, 28 when the datum temperature is reached. In operation, with a temperature below the datum, windings 34 are energized to cause reduction of the impedance of windings 30 and consequent increase in heater current, the effect being augmented by the flow of heater current in feed-back windings 33. A further thermistor responsive to the oven temperature may be included in a further bridge circuit, Fig. 5 (not shown), with a fixed resistor and two equiresistant windings of a balanced relay, whereby deviations of temperature from the datum are reflected by unequal currents in the relay windings, which cause the selective making of relay contacts to ring one of two alarms. In modifications, the heaters 27, 28 are in series with the A.C. windings 30, and the thermistors are replaced by temperature sensitive resistance wire wound on the oven with heating coils 27, 28.

A disc brake comprises an annular disc fixed at a location intermediate its peripheral edges to a support member fast with the vehicle wheel to be braked and a caliper housing 21 having an hydraulic piston and cylinder device 34 is located on the side of the disc remote from the disc support member and the caliper housing 21 is connected to a non-rotatable support 39 through the medium of a movable link 25 articulately connected by pins 24, 41 to the caliper housing and support 39, respectively, the pins 24, 41 being arranged parallel to each other in a plane parallel to the plane of the disc such that the caliper housing is automatically capable of adapting itself to the conditions of wear and deformation of the brake components. An alternative embodiment is disclosed in the Specification wherein an alternative mechanical actuating mechanism is provided, the hydraulic piston and cylinder mechanism is provided with an automatic adjuster of the kind disclosed in Specification 873,522. An automatic adjusting device is disclosed in the embodiment shown in Fig. 3 wherein if the clearance 67 between a spring 66 wound round a tubular part 65 fast with the cylinder and a cage 68 is sufficient the spring 66 will not move. When wear of the linings takes place the clearance 67 will be inadequate and the cage 68 will thrust against the spring causing it to slide with friction over the outer surface of the tube 65. On release of the brake, the assembly consisting of the linings 53, the piston 34 and the cage 68 cannot move back until the cage 68 abuts the spring 66, and, since the latter has been moved forward to adjust for wear of the linings, the return action is reduced by this amount. An inner (49) and an outer (60) brake lining is provided on either side of the disc. The lining 60 on the same side as the disc support is bonded on to a removable backing-plate 61 screwed to the caliper housing 21, the inner lining 49 being carried by retaining pegs 51 provided on the movable link 25.

Abstract: 907,299. Filter-tips. EASTMAN KODAK CO. Nov. 7, 1958 [Nov. 7, 1957], No. 35787/58. Class 130. [Also in Groups VIII and IX] Filter-tips are made from a tow comprising parallel crimped continuous filaments, the crimps in any one filament being out of register with those of adjacent filaments. The filaments may be of cellulose acetate with an acetyl content of 38-41%, a denier of 2-16, and more than 4 crimps per inch. The tow may be made by subjecting a tow of 20,000-250,000 of such filaments conditioned with a lubricant such as mineral oil, to a first tension to stretch the filaments and temporarily remove the crimps, applying a second tension to different lengths of adjacent filaments to maintain the crimps in straightened condition whereby the crimps in adjacent filaments are drawn out of register with one another, and relaxing the tension to restore the crimps in out-of-registry condition. In Fig. 2 a tow 15 having been opened by air-jets at 16 is passed between two pairs of rubber-covered rollers at 19, 22, the first pair being braked so that the filaments are tensioned; it is then conducted to a further pair of rollers 26, 27 positioned at an angle to the others and thence to a second opener 31 and a chamber where droplets of plasticizer (examples given) are deposited at random intervals along each filament. The tow is conducted by rollers 35 to a former 37 of the filter-rod device of Fig. 5. Here the tow is laid on a wrapper on an endless belt which has been made into U-form at 46; the wrapper is lapped around the tow at 47 leaving one edge 48 standing which is coated with adhesive at 49, smoothed over at 51 and sealed by heat at 52. The rod is heated at 54 to cause the filaments to bond at the points to which plasticizer was applied, and severed at intervals at 55.
