Title: Improved means for controlling the mixture of fuel and air supplied to internal combustion engines
IPC: F02D41/30
Filed: 1945-12-14
Abstract: 600,895. Gas turbines. BAINES, J. K. W., FLETCHER, K. A., and BURNS, Ltd., J. Dec. 14, 1945, No. 33945. [Class 110 (iii)] [Also in Groups XXVII and XXXV] In an apparatus for controlling the proportions of air and fuel. in combustible mixtures, the grid bias of a thermionic valve in an amplifier is varied in accordance with the composition of the exhaust gases, the amplifier output controlling the air or fuel supply electromagnetically. Variations in the amount of oxygen in the exhaust gases alter the resistance of a heated tungsten filament C situated in a byepass B of the exhaust pipe A and cause fluctuations in the output of an amplifier D which actuate an electromagnet G to control the fuel supply from a pump H to the nozzle L. The filament C forms one arm of a Wheatstone's bridge CMNO, Fig. 4, the arm Q of which is earthed at R and connected to the control grid S of a pentode T, the anode of which is connected to the grid U of a tetrode V having two relay coils W, X in its anode circuit which control the circuits of solenoids 3, 4, actuating a fuel metering valve 7 suspended mid-way therebetween from a spring 6. Variable resistances 9, 10 adjust the relative forces exerted by the solenoids 3, 4, and the amplifier is supplied with current from a power pack E having a switch operated by the ignition key. In a modification, the electromagnet actuates the control-rod of a Bosch or C.A.V. pump and the device may control a carburetter, e.g. of the S.U. type, the suction plunger being controlled by the solenoids. The tungsten filament may be replaced by a selenium cell and infra-red beam, the intensity of which varies with the amount of carbon or unconsumed fuel in the exhaust gases.

Title: Improvements in or relating to portable stages, platforms and the like
IPC: A63J1/00
Filed: 1929-11-08
Abstract: 342,018. Portable stages and platforms. SMITH, S. J., 5, Lloyd Place, Chelsea, London. Nov. 8, 1929, No. 34112. [Classes 20 (i) and 20 (ii).] A portable stage, platform, or the like comprises a series of open-sided crates each having a permanent top deck and capable of being nested to form a compact unit when required for transport. In one construction, a stage comprises a number of spaced crates 1, Figs. 1, 3, having decks 3 secured to beams 4 which extend from the fronts to the backs of the crates and are secured to front and back top rails 5. The side edges of the decks 3 terminate short of the sides of the crate to form shoulders 7 upon which rest bridge-pieces 8 which bridge the gaps between the crates. Projections on the undersides of the bridge-pieces engage upstanding plates 11 on the crates and hold the bridgepieces firmly in position. Sliding bolts 13 are provided at the four corners of each crate and engage holes in the bridge-pieces to hold these parts together when the stage is erected. A number of rows similar to that shown in Fig. 1 are arranged side by side when a platform of greater depth is required. In order to connect adjacent rows, the bridge-pieces 8 are each provided with a plate 15, Fig. 11, pivoted on a pin 19 and having three holes 21, 22 and 23. In the inturned position shown, the hole 21 is engaged by the bolt 13 of the adjacent crate in the same row. In the operative position, the plate 15 is rotated about the pin 19 until the said bolt can engage with the hole 22. In this position, the hole 23 is engaged by a bolt 13 of a crate in the adjacent row to lock the two rows together. When a bridge-piece is at the end of a row, it is supported by a tie-bar 29, Fig. 15, the hooked ends 30 of which are passed over the top rails 5 of the crates on either side. Extra struts are provided to support bridge-pieces which are at the corners of the stage. The shoulders 7 of those crates at the edge of the stage are filled by special filling-pieces. The crates of one row are of the same height but vary in dimensions from side to side and from front to back. so that they may nest one within the other. The nesting operation is performed by inverting the largest crate and by placing the others therein in order of size. The open sides are covered by the bridge-pieces which have eyes which engage hooks 43 on the largest crate. Spare parts may be stored in the box thus formed. The Provisional Specification also describes (1) a modification wherein the bolts 13 are arranged on the bridge-pieces and (2) a method of securing the crates together in the operative position when the same are erected side by side.

Title: Apparatus for monitoring the production of tablets in a tablet making machine
Inventor: FURTWAENGLER RUDOLF
IPC: G01G3/142
Filed: 1968-07-18
Abstract: 1,216,517. Rotary tablet making machines. CIBA Ltd. 18 July, 1968 [21 July, 1967], No. 34300/68. Heading B5A. [Also in Division G1] In a tablet making machine in which a plurality of tablet stations 2 each equipped with a pair of punches are brought successively past a point 17 where a mechanism, Figs. 1 and 2 (not shown), applies force to the punches to form a tablet, the weight of each tablet is monitored by measuring the applied force by means of one or more resistance strain gauges attached to the mechanism. The strain gauges are connected in a bridge circuit 13 and produce pulse signals which are applied through an amplifier 14 to an amplitude discriminator circuit 15 having upper and lower discriminator levels a and b. Pulses whose maximum amplitudes fall outside the levels, corresponding to tablets whose weights are respectively above or below a desired weight range, produce signals which enter shift registers 16a and 16b. The operation of the machine is controlled by a timing source 24 which advances the shift registers in step with the advance of the tablet stations. The final stages of the shift registers control a reject station W 1 , the number of stages in the registers equalling the number of tablet positions between the formation point 17 and reject station W 1 . Thus a signal corresponding to a tablet of incorrect weight actuates the reject station coincident with the arrival of the tablet at the station.  Counters 23 total the numbers of over and and under weight tablets which are rejected. To allow for a major mal function of the machine which results in the production of a succesion of tablets of incorrect weight, a logic circuit 19 incorporates "AND" circuits, Fig. 4 (not shown), which may be connected to selected groups of shift register stages to detect the production of a succession of incorrect weight signals. The logic circuit actuates a clutch 31 to terminate the drive to the machine from a motor 30, operates a second reject station W 2  and also operates alarm and other signalling circuits 20, P. The mean value of the maximum values of the strain gauge signals may be measured by a discriminator circuit, Fig. 5 or 6 (not shown), in which the discrimination level is shifted by the signals until on the average the level is exceeded and not reached the same number of times. A meter 22 may be switched to indicate the mean level and levels a and b in discriminator circuit 15. An oscilloscope 21 monitors the operation of strain gauge bridge 15. Preferably the strain gauges comprise a pair of elements, one subject to compression and the other to tension, which are connected in the bridge circuit to achieve temperature compensation.

Abstract: 899,300. Spinning and finishing yarns. T.M.M. (RESEARCH) Ltd. Oct. 5, 1960 [Oct. 12, 1959], No. 34553/59. Drawings to Specification. Class 120(3) A process of manufacturing bulked yarn from continuous synthetic, e.g. polyamide, filaments comprises the step of stretching undrawn or partially drawn filaments in the cold state by twisting, e.g. false-twisting. A separate stretching operation may be additionally effected before, after or simultaneously with the twisting operation. Multifilament yarn may be passed through the nips of feed and delivery rollers and twisted therebetween by a false-twisting unit to a condition in which any further twisting would break the filaments.' No stretching action need be obtained from the rollers, although there is a speed differential therebetween to take-up the extra length produced by stretching. On leaving the false-twister, the filaments assume a bulked appearance when released, dependent on the combination of stretch and twist. The bulked yarn is collected on a drumwound package or wound (with some added low twist, e.g. 0À5 turns per inch) by a ring and traveller. Alternatively, undrawn yarn is fed from a single pair of feed rollers to a ring and traveller operating under high tensions sufficient to insert about 70 turns per inch and stretch the filaments. The twist is then removed, or partially removed, by use of another ring and traveller.
