Filed: 1966-05-18
Abstract: 1,133,272. Automatic temperature control. DOLE VALVE CO. June 21, 1966, No.27723/66. Heading G3R. [Also in Division G1] A temperature control system for a heated area 62 e.g. the interior of a motor vehicle comprises a temperature responsive actuator 1 located in the area 62, and which is in the form of a continuous bi-metal strip 9 having a plurality of sinuous bights and interconnecting segments, the bights being secured in two fixed parallel electrically insulating arms 10, 12 with an intermediate actuating arm 11 connected by a rod to a flexible diaphragm 32 controlling an aperture in a conduit 20- 28 between a vacuum source 55 e.g. the vehicle engine inlet manifold and a servo 57 which regulates the amount of heat fed to the area 62 and an electrical circuit adapted to pass a current through the strip 9, this current being under the control of two thermistors, one, 44, in the air inlet 61 to the vehicle heater and the other, 42, in the duct 60 leading from the heater, whereby the degree of flexure of the strip 9 and thus the quantity of heat fed to the area 62 is a function of the electric current flowing therethrough as well as the temperature of the heated area. This arrangement allows constant regulation of the amount of heat fed to the area 62 in spite of fluctuations in air intake temperature and heater output. The electric circuit is fed by a battery 48 and adjustment of a variable resistor 45 allows a desired temperature to be selected. Shunt resistors 38, 39 are provided for the thermistors 42, 44 to maintain a relatively constant bias temperature. The element 9 is arranged to move the actuating arm 11 downwardly in Fig. 1 to flex the diaphragm 32 and the servo 57 is connected to actuate a control 58 e.g. a flap valve in the duct 60. The arms 10, 12 and the element 9 are supported by rigid columns 4, 5, 6, 7 but these may be replaced by two flexible metal sheets, one for each arm, to allow for movement of the arms 10, 12 as the element 9 flexes. Also, the bright portions of the element 9 may be rectangular if desired.

Title: Improvements in tobacco smoke filters
IPC: B01D39/18
Filed: 1954-09-28
Abstract: A tobacco smoke filter comprises synthetic fibres, e.g. nylon, cellulose acetate, viscose rayon and polyester fibre, having diameters of 0,1 to 2,0 microns, mixed with a greater quantity of carrier fibres of substantially larger diameter e.g. cotton, rayon, wool, or nylon fibres with diameters of 10,0 to 25,0 microns.  The synthetic fibres may comprise up to about 30 per cent by weight of the filter material and they are first opened or separated by a crushing or grinding operation in a hammer mill followed by screening and further opening on a picker and carding device while simultaneously blending the opened fibres with a portion of the larger diameter fibres, the remainder of the larger diameter fibres being added to the mixture in a second picker and carding machine. The resulting mixture is passed to a finishing carding machine from which the fibre mixture emerges in the form of a web or sliver. Alternatively the mixed fibres may be fed into an air blast which deposits them as a web on a rotating cylindrical drum.  The web of mixed fibres may be compressed into a sliver and, after wrapping in a tubular wrapper, severed to form filters suitable for incorporation into a cigarette or for use in tobacco pipes or cigarette or cigar holders.  A binding material may be applied to the fibres to bind the fibres together.  The binder may be a thermoplastic or thermo-sensitive material such as a synthetic resin, examples of which are given, and may be applied to the fibre mixture or to the large diameter fibres only. Alternatively the binder may be a fibrous thermosensitive material and may replace part or all of either the small or large diameter fibres, the fibre mixture being heated to cause the fibres to bond together at their intersections.  The sliver of mixed fibres may be strengthened by braiding with cotton thread or webs of the mixed fibres may be interleaved with crepe paper, the sliver or webs being subsequently wrapped in a tubular wrapper to form a rod in which the strengthening threads or the crepe paper run longitudinally of the rod.

Title: Improvements in method of controlling thread tension
IPC: B65H59/38
Filed: 1946-09-25
Abstract: 631,956. Thread tension arrangements UNITED STATES RUBBER CO. Sept. 25, 1946, No. 28678. Convention date, Dec. 14, 1945. [Class 120 (ii)] [Also in Group XXXV] The tension of a thread is controlled by vibrating a portion of the thread passing between two fixed points, detecting the rate of vibration, and automatically regulating the tension applied so as to keep the rate of vibration substantially constant. A rubber thread unwinding from a spool 19, Fig. 3, is looped one or more times over a thread tensioning drum 20 and then passes over spaced grooved wheels 21, 22, and is wound on to a golf ball B. The section between wheels 21, 22, is vibrated at its natural frequency by two air jets at right angles to each other, Fig. 4 (not shown). The vibrating thread periodically interrupts a beam of light from lamp 50 focussed on to a photo-cell 52 to produce a varying voltage across resistor 53, Fig. 7. This voltage is amplified and given a substantially sinusoidal wave form in stage A and applied to a frequency discriminator B wherein a departure from the resonant frequency of circuit 74 changes the anode voltage-grid voltage phase relationship in each triode of the push-pull connected pair 70, 71, thereby varying the voltages across load resistors 79, 80. These voltages are applied to a pair of tetrodes 84, 85 which energize solenoids 42, 43, the armatures 44, 45 of which are connected over pulleys, Fig. 6 (not shown), by a wire 39, Fig. 5, looped around a pulley 36. Rotation of pulley 36 varies, by means of the threaded shaft 34, the tension on a brake band 30, and so controls the thread tensioning drum 20. The solenoid armature movements are damped by dash-pots 46.
