[Also in Group XIX] A combined folding rule and square comprises a pair of strip-like members 20, 21, connected by a knee-jointed strut 33 pivotally attached to the members 20, 21, intermediate their ends, the strut 33 being in alignment with the members 20, 21, when the latter are aligned and ends 25 are juxtaposed, Fig. 2, the device then forming a rule, and the strut 33 extending across the angle between members 20, 21, when the latter are at right angles to each other with their opposite ends 26 juxtaposed, Fig. 3, and the device forms a square. The ends 26 are formed with interengaging projections and recesses. Each member 20, 21 may be formed from a pair of plates with an intervening spacing member, the latter being cut away to form recesses for the strut 33.

Abstract: 1,270,167. Cathode-ray tube circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 1 July, 1969 [4 July, 1968], No. 33103/69. Heading H4T. The control electrodes and the cathodes of a picture display tube are connected to a first terminal 47 of a voltage supply source via impedances 26, 28, 30 and 36 which are of low value relative to the impedances formed by transistors 25, 27, 29 and transistor 34 (when not bottomed) which connects the cathodes and the control electrodes to a second terminal 48 of the supply source. With this arrangement variations of equal magnitude occur at the control electrodes and the cathodes when the voltage of the supply source. Blanking of each beam is effected by field flyback pulses at terminal 1 and line fly-back pulses at terminal 50 which cause transistor 34 to bottom and thus to bring the control electrodes to substantially earth potential (terminal 48). Transistors 4 and 15 forming an electronic switch and the double limiter formed by diodes 17, 18, 19 and 20 constitute a known noise suppression circuit for the S.E.C.A.M. colour television system.

Abstract: 1,156,957. Threshold circuit. CORNING GLASS WORKS. 19 July, 1967 [27 July, 1966], No. 33203/67. Heading G4P. [Also in Division G3] A threshold circuit with an adjustable bias comprises a proportional amplifier having a power jet 42, Fig. 2, and two control inputs 52, 56 to the right-hand one of which the bias is applied, and a bi-stable wall-attachment amplifier having a main jet 26 and two control inputs 34, 36 connected, as shown, to the outputs of the proportional amplifier. In operation the steady bias directs the power stream in the proportional amplifier along the left-hand channel 44, which causes the bi-stable amplifier to direct its power stream to its right-hand output channel 32, and the bi-stable amplifier only switches to its other condition when, and for the duration of which, a control signal 56 applied to the proportional amplifier exceeds the bias signal. In a modification (Fig. 4, not shown) three stages of proportional amplification prior to the bi-stable amplifier are used.

Abstract: 1508144 Weighing E A WAHL 8 Aug 1975 [21 Aug 1974] 33217/75 Heading G1W [Also in Division B8] Fibrous material is fed from a hopper to an endless belt 11 under the discharge opening of the hopper by means of a rotatable drum which is driven by a D.C. motor 53, and in order to maintain a constant, predetermined feedrate of the material discharged from the belt 11 (at the righthand end of the latter in Fig. 5) a portion of the belt to the right of leaf springs 20 (only one shown) is pivotally mounted by the leaf springs 20, and the weight of material on that pivotallymounted portion of the belt 11 is sensed by a load cell 36 which provides an output village proportional to the weight of material thereon. A desired material feedrate is established by a manually-adjustable set point potentiometer 86 which applies a constant voltage to an equalizer 87 which compares the signal from the potentiometer 86 with the signal from a multiplier 85 connected to the load cell 36. The error signal is applied to control circuitry 89 which controls the motor 32 driving the belt 11, in order to provide the pre-set material feedrate, but if this adjustment is not sufficient the control circuitry 89 also changes the speed of rotation of the drum contained within the hopper.

Title: Improvements in and relating to condensate removing systems
IPC: F16T1/14
Filed: 1927-12-09
Abstract: 301,213. Irving, R. Bell-, and Sand well, R. Dec. 9, 1927. Drying. - The main condensate outlet of a steam chamber, such as a rotary paper drier, is continuously sealed by the condensate and is normally closed, there being means for opening the main outlet in response to an initial discharge of condensate through an auxiliary outlet. fig. 1 shows one form of apparatus applied to a rotary paper-drying drum 1, to which steam is supplied through the hollow shaft 2 from a header 6. Extending through the shaft 2 and terminating adjacent the bottom of the drum are main and auxiliary condensate discharge pipes 7, 14 respectively, the former being connected by a pipe 9 and through a normally closed valve 10 to a condensate discharge header 13. The pipe 14 is connected to a chamber 18 containing a bucket 21, which is normally maintained floating in the position shown. When the condensate in the drum 1 reaches the end 16 of the pipe 14 it passes up this pipe into the chamber 18, and overflows into and sinks the bucket 21, which through a lever 23 opens a valve 24 and allows liquid to pass from the bucket, through a centre tube 21<1> and pipe 26, to the upper side of a diaphragm 29, which is thus depressed to open the main condensate discharge valve 10. When the fall of the condensate level in the drum 1 uncovers the end of the pipe 14 steam passes up this pipe and forces the condensate from the bucket 21, and the parts return to the position shown, the condensate above the diaphragm 29 being forced out through a choke coil 28 by a counterweight 11. When the end of the pipe 14 is not covered by the condensate steam and accumulated air pass up it to the chamber 18, which is connected to the header 13 through a choke coil 19 which limits the flow. A modification is described in which the space below the diaphragm is in communication with an auxiliary or the main condensate header, instead of with the atmosphere, thus enabling the apparatus to be used whether the dryer pressure is above or below that of the atmosphere. Fig. 3 shows a further modification, in which the condensate passing up the pipe 14 accumulates in a vertical pipe 35 and so produces a head pressure on the diaphragm 29, which is thus caused to open the condensate discharge valve 10. When the condensate level falls, steam passes up the pipe 14 and forces the condensate from the pipe 35 into the surrounding chamber 36, from which it passes to the header 32, the valve 10 being then closed by a counterweight 11. The application of the system to the drying portion of a paper machine is illustrated, the drying drums being in two series, and the condensate from the first being discharged into a low-pressure receiver and used to produce flash steam for heating the second series, the condensate header of which is maintained under a vacuum. Specification 28162/96, [Class 64, Heating], is referred to.

Abstract: 632,305. Change-speed gear. SCINTILLA, Ltd. Nov. 13, 1946, No. 33712. Convention date, Aug. 5, 1944. [Class 80 (ii)] In a hub containing an epicyclic gear rendered operative or inoperative by a roller clutch actuated by centrifugal weights, the weights are pivotally mounted in a casing coupled to the internal ring of the roller clutch which forms the annulus of the epicyclic gear. A planet carrier 4 carries the driving sprocket 3 and is journalled on the fixed spindle 1, with which is rigid the sun gear 6. The carrier 4 is rigidly connected with the driving member 10 which is in one-way clutch connection 26 with the hub shell 16, and in similar connection in the opposite sense with a back pedalling brake 30 through a oneway clutch 27. Journalled on the member 10 and driven by a tongue 18 from the annulus 9 is a casing 12 supporting the pivots 14 of two fly-weights 13. The weights 13 are normally held inwards by springs 15 and so, through the projections 24 engaged by the slats 25 of the weights, the cage 23 for a jamming roller free-wheel 22 between the annulus 9 and the hub shell 16 is held in the declutched position. At a predetermined speed the weights move out against the springs and rotate the cage 23 to engage'the clutch 22 which drives the hub shell 16 at a higher speed and causes the clutch 26 to overrun. The weights 13 are pivoted as near the axis of the hub as practicable to ensure a substantially circumferential movement of the slots 25 which are cut 180 degrees from the pivots.
