Patent GB-384816-A (GB)
Title: Transmission gearing
IPC: F16D67/00
Filed: 1931-12-24
Abstract: 384,816. Motor-vehicle driving-gear. ALVIS CAR & ENGINEERING CO., Ltd. and CLARKE, G. T. SMITH-, Holyhead Road, Coventry. Dec. 24, 1931, Nos. 35665 and 35666. [Class 79 (ii).] Transmission gearing wherein the driving shaft is connected with the driving element of a fluid coupling and one element of a planetary train, the driven element of the fluid coupling is connected with a further element of the planetary train, and the remaining element of the planetary train is connected with the driven shaft, is combined with supplementary gear whereby one or more changes of ratio or reverse drive can be effected. The fluid coupling is preferably of the F÷ttinger type, wherein a casing 2, caused to revolve with the crank shaft 5<1>, is formed with internal cups 3 which act through the fluid medium on cups 4 connected with an internally toothed annulus 6. An extension 5 of the crank shaft forms or carries the sun wheel of the planetary assembly, and the planet wheels 8 engaging the sun wheel and the annulus 6 are carried by a member 9 mounted on the driven shaft 10, which passes through a gland 11. A variable-speed gear is thus provided in which the ratio depends upon the degree of slip between the cups 3, 4, which is determined by the load on the driven shaft. If desired, the planetary gear may be located outside the casing 2. As shown, the supplementary gear comprises an epicyclic reversing gear in which the sun wheel 17 is mounted on the shaft 10, the internally toothed annulus 18 is mounted on the shaft 19 communicating with the road wheels, and the intermediate planet wheels 16 are carried by a drum 15. This drum is normally caused to revolve with the shaft 10 by means of spring-pressed clutch members 13, thus imparting a direct drive to the shaft 19. Operation of the pedal 20 disengages these clutch members through the action of links 21, and the application of a brake band 14, either by the further depression of the pedal 20 through suitable mechanism (not shown) or else by a separate control, causes a reverse drive to be imparted to the shaft 19. In a modification, the device is combined with a change-speed gear of standard type for use when the range provided by the device itself is inadequate, and in this case it is necessary to bring the shaft 10 to rest when changing gear ; this may be effected by a band brake acting on a drum on the shaft 10 and actuated by any suitable control, but preferably by a trigger on the gear lever which also serves to lock it in its various positions. If desired a clutch may also be provided between the crank shaft 5<1> and the sun wheel 5, as described in Specification 385,112, [Group XXIV]. The supplementary gear may be operated by pneumatic, hydraulic, electric or other means.
Patent GB-630986-A (GB)
Title: Improvements in and relating to thermionic valve amplifiers
IPC: H03G9/08
Filed: 1946-12-03
Abstract: 630,986. Valve amplifying circuits. BUSH RADIO, Ltd., and HARRISON, W. H. Dec. 3, 1946, No. 35775. [Class 40 (vi)] In a low-frequency amplifier, maximum negative feed-back is produced. at the minimum gain setting of the gain control resistor by connecting the tapping point of the resistor to the input of a first amplifying stage and connecting the end of the resistor corresponding to minimum gain to a point upon a cathode bias resistor in a succeeding stage, the voltage at this point being opposite in phase to that at the input of the first amplifier. The Figure shows the detector and L.F. amplifier stages of a superheterodyne receiver in which maximum negative feed-back is applied at low gain settings of the volume control. Signals from the I.F. stages are detected and the resulting L.F. signals appear across the diode load resistor R1 and are applied to the grid of the triode amplifier V1 via the volume control potentiometer VR 1. The lower end of this potentiometer is returned to earth via the cathode resistor R5 across which there is a negative feed-back voltage from the power amplifier stage V2. As the tapping 12 of the volume control VR1 moves towards the low gain position the negative feed-back voltage increases and thus when the receiver is used on relatively strong local signals the maximum amount of negative feed-back is available to correct for the attenuation of the higher audio frequencies which would otherwise occur. Capacitor C5, which acts as a shunt to the feed-back voltage at the higher frequencies has its maximum effect at low gain settings of the volume control so that at low levels of gain the higher frequencies are amplified to a relatively greater extent than the remainder of the frequency range. The amplifier may be made to simulate the frequencyresponse of the human ear by including a network, Fig. 2 (not shown), in the feed-back path at 17 so that the amplification of the higher and lower audio frequencies is respectively greater than that of the mid-band frequencies at low gain settings of the volume control.

Patent GB-911378-A (GB)
Title: Improvements in or relating to stocking finishing machines
IPC: D06C5/00
Filed: 1960-10-27
Abstract: A method of finishing a stocking includes the steps of slipping a crude stocking over a former, passing the former and stocking through devices for fixing washing dyeing or bleaching and drying, grading the stocking as to quality by visual inspection and as to length by automatic means, and removing the finished and graded stocking from the former by automatic means just prior to the automatic deposition of the stocking at a predetermined location. In the arrangement shown, a batch of formers charged with stockings is in position A1, another batch is receiving washing fixing and dyeing treatment in the pressure container 2 at section A, a further batch is receiving bleaching and drying treatment at B, a batch of completed stockings is in position B2 and a further batch is being inspected and graded at C. Subsequent to grading the stockings pass a measuring device at D, are removed from the formers at E and delivered according to grade and size into carriage 54.  After the formers are stripped at E they pass to section G where they are recharged and then on to section G1 ready for transfer to section A1.  The formers are conveyed through the various sections by continuous conveyer belts.  The formers in sections A1 to B2 are moved by means of compressed air cylinder 9 operating draw bar 10 and the transverse conveyers chains 5 are driven by electric motors.  The track 8 outside the pressure <PICT:0911378/IV (b)/1> <PICT:0911378/IV (b)/2> chamber 2 is connected with the rigid track 15 inside by a small track member 14 on an inner body 16 rotatably mounted in chamber 2 and also carrying the closure door 12 for the chamber 2.  When the formers are transferred to section C they initially occupy position C1, they are then opened out to position C2 to allow inspection and grading.  To allow for quality marking, each former is provided with a lever 22 (Fig. 3) which has three positions.  The inspector places the lever in the position corresponding to the grade of the stocking and the lever operates switches 23a, 23b at section D to transmit a control impulse to the carriage 54.  Also at section D the length of the stocking is measured by photo-electric cell means operating in conjunction with holes in the former as indicated at 24 and 24a (Fig. 3) and an impulse according to length is transmitted to the carriage 54. Scanning pins or electrodes may be used as alternative measuring means.  At E the stockings are removed from the formers by pneumatically operated grippers and transferred to a continuous belt 45 to which the stocking is held by a suction device and from the under side of the belt 45 the stocking is delivered into the appropriate compartment of carriage 54.  The carriage 54 is driven by a screw and nut mechanism operated by motor 58 and is stopped in position corresponding to the grading by control members 59 which are actuated in dependence upon electric impulses transmitted from station D according to quality and length.
