Patent GB-712012-A (GB)
Abstract: 712,012. Variable-speed gear. CALZONE, F. July 23, 1952 [July 24, 1951], No. 18655/52. Class 80 (2) [Also in Group IX] The spindle shaft 39 of a continuous spinning-machine is variably driven through a stepped-planet train of which one sun 9 is invariably connected through belts 15 to a parallel motor-driven input shaft 1; the other sun 10 is fast on a shaft 5 driving the output shaft 39 through a manually-changed twospeed sliding-wheel gear 34 ... 37; whilst the planet-carrier 8 is integral with one flange 6 of a variable pulley driven by a complementary spring-closed variable pulley 2 on the input shaft. The axially-movable flange 7 of the driven variable pulley is controlled by three independent means; firstly manual. 23, for adjusting the mean speed; secondly automatic, by the eccentric shaft 53 of the machine to avoid the increase in thread tension which would otherwise occur as the winding approaches the apex of the reel-cone; and thirdly automatic by a shaft 54 turned by the click-wheel of the machine tc vary the speed in accordance with the number of layers in the winding, and also to compensate for the gradual change from initially cylindrical to conical reel form, thus co-operating with the eccentric-shaft 53 in maintaining a constant thread tension. These controls take effect as follows:-A sleeve 18, axially movable on but rotating with the shaft 5, and movable axially with but rotatively connected to the pulley flange 7, bears against a ball thrust bearing 19, the outer race 19 of which can be screwed along a thread on a sleeve of a slidable member E, by engagement of its toothed periphery with a pinion 21, turned through a worm gear 22 by the manual adjustment 23. The slidable member E supporting the thrust bearing 19 is axially movable by turning a face cam C, effected through a pinion 25, side-shaft 26 and chain 29, by the eccentric-shaft 53, constituting the first automatic adjustment. The axial position of the face cam C is varied by the second automatic adjustment, the winding layer control 54, which turns a worm-wheel 31 screwed internally to a sleeve 30 which supports the face cam axially. Manually-set screws 51 in the slide E vary the radial position of guided parts carrying rollers 24 through which the slide E bears on the face cam C, thus providing an adjustment for the control effect of the cam.
Patent GB-745042-A (GB)
Abstract: 745,042. Automatic control of resistance. BRITISH BROADCASTING CORPORATION. Nov. 19, 1952 [Aug. 21, 1951], No. 19735/51. Class 38 (4). [Also in Group XXXVI] In a bridge circuit of the type in which one arm acting as a standard arm includes a thermistor, random variations of the conductance of the thermistor are prevented by connecting the thermistor also in one arm of an auxiliary bridge circuit which varies the supply of heating current to the thermistor to maintain the auxiliary bridge balanced. As shown, thermistor 11 forms with condenser 12 one arm of a high-frequency bridge 13 and at the same time forms an arm of a bridge circuit 21 which includes a variable resistor 22 and fixed resistor 44 in the other arm. Changes in conductance of the thermistor unbalance the auxiliary bridge and the unbalance voltage developed across a diagonal of the bridge is amplified in a conventional balanced D.C. amplifier and applied between grid and cathode to vary the conducting of a triode 25. This triode forms a load in parallel with the bridge and fed through a common resistor 27. Thus the bridge current and hence the resistance of the thermistor is varied to rebalance the bridge. The conductance of the thermistor may be found as a function of the valves of the other arms of the auxiliary bridge. The conductance of the thermistor may be varied by changing the setting of the variable resistor 22. This resistor may be in the form of a decade box the steps of which may be linked to a switch to control the current supply and keep the bridge substantially balanced.

Patent GB-2018436-A (GB)
Title: Porosity measurement
IPC: G01N15/08
Filed: 1979-02-02
Abstract: The porosity (gas permeability), of sheet material such as paper is usually expressed in terms of units of gas flow/unit sheet area/unit pressure drop across the sheet, and may be obtained from the measured gas flow F across the sheet at a fixed pressure drop PD or from the measured pressure drop at a fixed gas flow. One parameter is automatically set sequentially at a number (e.g. 3) of values near to a required value, the other parameter is measured at each, and from these readings the values of K and N for a relationship flow F = K(PD)<N> are ascertained for the sample under test in the region of the said required value of the one parameter. From this there is calculated the precise flow (or PD) at the exact required PD (or flow), and hence the porosity. The automatic setting of the flow rate at the close values, the calculation of K and N, and the calculation therefrom of the PD (or flow) at the given flow rate (or PD) and the porosity is achieved by means of a microprocessor. <IMAGE>

Patent GB-2056125-A (GB)
Title: Vehicle speed control system
IPC: B60K31/04
Filed: 1980-07-17
Abstract: In a vehicle speed control system an electrical signal (Vf) representing actual vehicle speed is compared with a stored signal (Vm) representing desired vehicle speed and any speed error is used in a servo loop (46, 16, 15, 10) to generate a control signal which tends to reduce the error to zero. In addition, signals (Vs, Vm) representing the actual and desired vehicle speeds are compared in a comparator (70) so as to produce a control system disabling signal when the difference between them falls outside predetermined positive and negative limits (e.g. because road conditions prevent the vehicle engine from driving the vehicle at or close to the desired speed). This disabling signal is used to switch the control system out of operation. <IMAGE>

Patent GB-2059632-A (GB)
Title: Fuel systems for gas turbine engines
IPC: F02C9/32
Filed: 1980-09-15
Abstract: A gas turbine engine fuel control has a main hydromechanical fuel flow control (10) and an electrically operable valve (11) in series with the flow control for speed limitation purposes. The valve (11) is controlled by a signal NL or NH derived from an engine speed transducer. A phase advance compensation circuit (13 or 14) advances the phase of the transducer signal and its output is applied to an error amplifier (15 or 16) which compares it with a datum (which may vary). The error signal is applied to a non-linear amplifier (17 or 18) the amplification factor of which increases when a certain error threshold is exceeded. The combination of phase advance and non-linear amplification ensures rapid limitation of speed without introducing stability problems. <IMAGE>
