Title: Improvements in tunnel kilns
IPC: F27B9/08
Filed: 1926-12-03
Abstract: 280,044. Woodall-Duckham (1920), Ltd., and Duckham, A.. M. Dec. 3, 1926. Tunnel kilns.-In an annular tunnel kiln having an open firing-zone and muffled preheating and cooling zones, gases are withdrawn from the kiln on both sides of the firing-zone. The kiln, which is shown in developed section in Figs. 2 and 3, is of the same general construction as that described in Specification 212,585, and comprises a firing-zone g supplied with heating-gases from a combustion chamber d through vertical side wall flues f, a preheating-zone n with horizontal wall flues k', through which the heating-gases from the firing-zone pass on their way to the chimney flue l, and a cooling-zone o also with wall flues e<1>, which convey cooling-air and deliver it through the conduit e<2> to the combustion chamber. In the preheating and cooling zones are outlet ports r<1> in controlled communication through flues p, q with the main stack flue, and through these ports gases are withdrawn in order to minimize convection currents in the cooler portions of the kiln. The heating-gases from the flues fare caused to impinge upon the sides of the goods-supporting platform, and pass in part to the kiln chamber through the clearance spaces between the platform and the walls, and in part to radial flues h<1> formed beneath the platform and branching from an annular flue s. The ports k leading to the wall Rues k<1> are situated at the same level as the delivery ports from the flues f. Transverse walls i of a temporary nature are built upon the travelling hearth h to divide the kiln into a number of chambers, and at the entrance and exit a tight joint is made with these walls by adjustable lintels t. Escape of gases from the flues h<1>, s at the entrance and exit of the kiln may be prevented by dampers or slides.

Abstract: 1,090,158. Transistor oscillators. G. & E. BRADLEY Ltd. July 18, 1966 [July 20, 1965], No. 30792/65. Heading H3T. [Also in Division G3] The output voltage of an oscillator const i tuted by a transistor stage 10 and following stages 11 is stabilized by correctively varying the gain of the stage 10, this variation being effected by controlling the emitter current of the transistor 13 in the stage 10 in dependence upon changes in the output voltage. The stage 10, which comprises the transistor 13 connected in the common-emitter configuration, biasing resistors 14, 15, a by-pass capacitor 25 and a transformer 16 tuned by a capacitor 17, is made to oscillate by the provision of a positive feedback path 18 connected between the oscilltor output terminal 12 and the base of transistor 13. A comparator constituted by a rectifier 19, resistors 20, 21, a capacitor 23 and a reference source 22 produces a D.C. signal representative of output voltage variations, and this signal is applied over an amplifier 24 to control the emitter current of transistor 13, whereby the output voltage is stabilized at the desired value. In a modification (Fig. 2, not shown), the transistor 13 is replaced by two transistors (13a), (13b) which are connected in push-pull and which are controlled from the output of amplifier 24 by way of a further transistor (26).

Plane - trigonometry calculators.-In a gunnery calculating-apparatus for determining the leading angle and predicted range when firing at a'moving target, a point and a line have to be relatively adjusted into coincidence whereupon the line by its orientation and length gives the required particulars. The problem to be solved is shown in Fig. 1 wherein A is the observer's post, B the gun position and C the object moving along the path C D with a velocity Vg, in the time T, i.e., the time of flight of the projectile, the delay due to laying &c.

Abstract: 1468002 Variable threshold circuit; video thresholding MULLARD Ltd 29 July 1975 31690/75 Headings H3T and H4F A video waveform thresholding circuit comprises : a comparator 71 for comparing a video signal on line 77 with a threshold level in store C to produce a binary output; and a control circuit 72, 98 which receives the comparator output and which is arranged to increment the threshold store during a first sample T1 of the video waveform 15 and to cease incrementing the store and provide an output on line 99 during a second sample, T2, during which the signal is amplified 16. The video signal is derived from a linear array of diodes 70 used for scanning a character, scanning being controlled by a shift register 75. A counter arrangement, Fig. 5 (not shown), produces a control signal on line 35 to initiate each scan and enabling controls signals on lines 36, 37 during the second and first scan respectively. During each positive-going portion of signal 15 the charge stored in capacitor C increments until it reaches V(T) at the end of the scan. During the second scan, a gate in 72 inhibits further change in charge and the voltage across capacitor C provides a threshold for the second sample, giving a clean two-level output from comparator 71 which is fed to output 99 via gate 98. The necessary amplification of waveform 16 is produced by making the time period T2 longer than period T1.
