Title: Method and apparatus for determining and recording parameters of textile fibres
IPC: G01N33/36
Filed: 1959-12-31
Abstract: 945, 545. Determining physical qualities of materials. CENTRE SCIENTIFIQUE ET TECHNIQUE DE L'INDUSTRIE TEXTILE BELGE ASSOCIATION SANS BUT LUCRATIE. Dec. 31, 1959 [Dec. 31,1958; Sept. 12,1959], No. 44435/59. Heading G1N. In an apparatus for determining the length distribution of fibres in a textile, a sample of the fibres terminating in a short predetermined length is taken and clamped between two sheets of material of low dielectric constant such as "Teflon" (Registered Trade Mark), in a metal frame 3, for passage between the electrodes 2d of a measuring capacitor 2, the fibres being moved in the direction of their length and being aligned at one end. The capacitor is narrow in the direction of movement and readings taken at set distances along the length indicate the proportions of fibres exceeding those respective set distances. The capacitor output is integrated to give an indication of the mean length proportionate to the cross-sectional area or "height" and the output of the first integrator is applied to a second integrator to give a second value by which the "beard" which is the length mean proportionate to the fibre cross-section and the mean length can be calculated. The integrators pass automatically to "hold" or "reading" when the aligned ends pass through the measuring device. The variation coefficient of length can be determined from the two integrator outputs. Narrow electrodes 2a, 2a<SP>1</SP> have earthed rings 2b, 2b<SP>1</SP>, on either side so that the potentials thereon are symmetrical, and are thin so that parasitic capacities are reduced. They may be silver or gold deposited by evaporation or spraying. Edge projections 2d maintain the sample in the centre of the capacitor and the whole is mounted in an indeformable casting. The frame 3 is mounted in a rigid "U" shaped chassis whereby mechanical or manual drive may be applied. The measuring condenser CM may vary the frequency of an oscillator, vary the central frequency of a discriminator, or, as in Fig. 9, be included in one of two parallel paths C5, L5 in the output of a crystal oscillator circuit to provide with path L6, C6 a differential output to a detector circuit and a voltage proportional to the instantaneous fibre mass at terminals out (1) (2). Capacitor C8 and resistor R10 are provided for calibration. The integrator stages comprise a D.C. amplifier the output of which is connected to the input through a condenser and the input of which includes a series resistor. The amplifier may be of conventional D.C. type of A.C. with electromechanical, thermionic or transistor choppers. Worsted may be driven directly through the capacitor. Methods of preparing samples are discussed and includes a mechanical sampler described with reference to Fig. 16 (not shown) A mathematical analysis is included.

Abstract: 950.020. Cooling systems for internal-combustion engines. M. BEHR, [trading as SUDDEUTSCHE KUHLERFABRIK JULIUS FR. BEHR.]. Dec. 18, 1961, No. 45348/61. Heading F4U. [Also in Division F1] In a supercharged internalcombustion engine having separate cooling water circuits for the engine 1 and for a cooler 3 for the air supplied by a supercharger 2, a connection 12 between the two circuits is opened by a thermostat 13 when the temperature in the air cooler circuit falls below a predetermined value, to transfer warm water from the engine cooling circuit to the circuit of the air cooler 3. In Fig. 1, each circuit has its own supply pump 4<SP>1</SP>, 4<SP>11</SP>, radiator 5<SP>1</SP>, 5<SP>11</SP> and expansion tank 7<SP>1</SP>, 7<SP>11</SP>, and the pipe 12 is connected from the outlet 11 of the cylinder block to the inlet of the pump 4<SP>11</SP>, the thermostat 13 being responsive to the temperature of the water flowing towards the cooler 3. At a predetermined temperature just above freezing, the valve 13 opens to admit warm water to prevent the water in the cooler 3 from freezing. A return pipe 14 leads from the cooler outlet to the inlet of the engine coolant pump 4<SP>1</SP>. In a modification, Fig. 2, the return pipe 14 is omitted and the return is effected through the expansion tanks which are combined in a single tank 15 and separated by an overflow baffle 1611. When water is fed from one circuit to the other through pipe 12, the level in the right-hand expansion chamber rises until it reaches the top of baffle 1611 when it overflows into the left-hand expansion chamber connected to the engine cooling circuit through return pipe 14<SP>1</SP>.

Abstract: 1,149,358. Automatic circuit breakers. TEXAS INSTRUMENTS Inc. 13 Oct., 1966 [24 Oct., 1965], No. 45854/66. Heading H1N. In a thermally responsive automatic circuitbreaker actuated by a push-button 44, Fig. 1, the contacts 148, 172 are retained closed by a thermally responsive latch 112, 124 and the push-button is latched in the contacts closed position by a ball catch 78, 86 when the contacts are closed. The movable contact 148 bridges a pair of fixed contacts 170, 172, Fig. 2, and is mounted on a U-shaped spring steel clip 158 attached to a bell crank 104 on the lower end of ball catch member 86 slidable within a bore 76 of the push-button 44. Spring 117 coupled between the bell crank 104 and a fixed plate 119 operates both to open the contacts when released by the thermally responsive latch 112, 124 and also to push the ball-catch member 86 upwardly in the push-button 44 to lock the push-button against return spring 70 by engagement of balls 80, 82 against shoulders 92 in the threaded mounting sleeve 24. The thermally responsive bimetal element 180, Fig. 17 is of inverted U-shape and mounted at its ends on a channel shaped bracket 190 carrying an adjustment screw 196 engaged between opposite arms of the bracket. The element 182 carries current between the fixed contact 172 and terminal 12, one of its arms being on an insulated mounting for connection to a terminal strip 178. Release of the catch 112, 124 is obtained through a sliding plate 204 engaged by the element 180. Ambient temperature compensation is provided by a second bimetallic element 122, Fig. 9, also of inverted U-shape and pivoted at the lower end of the arms in slots 136 of the casing. Sliding plate 204 engages the element 122 which is coupled to the thermal catch element 124 at the lower pivoted end and yieldingly held by a spring 126 engaging the casing 14. Since the bimetal elements 122, 180 act in opposition on the latch 112 with changes in ambient temperature the latch is unaffected by these changes. The casing is made in halves in which the thermal elements, fixed contacts and terminals are initially mounted before assembly. The push button 44 may be inserted as a separate assembly including the moving contact 148 and thermal operating slide plate 204 for engagement in opposite grooves 108, 110 of the assembled halves of the casing.
