Title: Improvements in or relating to amplifiers employing transistors
IPC: H03F3/26
Filed: 1953-02-11
Abstract: 731,393. Transistor amplifying circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Feb. 11, 1953 [July 8, 1952], No. 3879/53. Class 40 (6). An amplifier comprises two transistors having their outputs connected in pushpull, the inputs signal being connected with the same phase to the base electrode of one transistor and to the emitter electrode of the other. The basic circuit is shown in Fig. 1, wherein the input signal is applied via transformer E to the emitter and base of transistors T1 and T2 respectively and the output is taken via a transformer A having a split primary winding connected to the collector electrodes. In the arrangement of Fig. 1, the electrodes are biased as shown so that the emitters are 1 volt positive with respect to the corresponding base electrodes and the collectors are 19 volts negative with respect thereto, the primary of the output transformer being split to permit the biasing arrangement shown. The remaining Figures show modified arrangements wherein the biases are derived by the use of voltage-dropping resistors. For example, in Fig. 3, potential differences of one volt are developed across the resistors R1, R2 to produce biasing equivalent to that shown in Fig. 1. In other circuits biasing resistors are also arranged in one of the collector circuits. Figs. 5 and 8 (not shown), illustrate arrangements wherein in at least one transistor the emitter current exceeds the collector current. Figs. 7 and 8 (not shown), illustrate arrange. ments having resistance-capacity input coupling for the input.

Filed: 1967-01-26
Abstract: 1,164,504. Calculating apparatus. SPERRY RAND CORP. 26 Jan., 1967 [29 Jan., 1966], No. 4014/67. Heading G4B. A pin carriage comprises a frame 24, segments 25 having notches 25b and integral leaf springs 25a, and pins 16 received within the notches and formed with two notches adapted to cooperate with the leaf springs. The parts may be moulded in plastics material, the pins including an integral strip 16b cut away after assembly. The pin carriage is spring-loaded and mounted on guide rods 3, 4. Keyboards.-The keys operate associated plastics push rods 13 terminating in a collector bar 15 and a common T-bar 17 connected to a push rod 18. The keys carry studs 5 and are returned to their rest positions by a coil spring 23. A pin 16a is displaced by push rod 18 whenever a digit is entered in the associated column whereby a step-by-step movement of the carriage is achieved. Operating key.-An operating key 10 has an extension 10f engaging an opening 50a in a lever 50, Figs. 18 and 21. Depression of the key 10 pivots the lever 50 to move a cam 50c formed at one end. Cam follower 28 moves to free pawl 29 whereby coupling 29, 31 engages to transmit drive from an electric motor to shaft 33. On releasing the operating key, the lever 50 is restored to its central position by members 34, 35 and coupling 29, 31 disengaged. Carriage return.-A cam 39 fast with shaft 33 co-operates with a follower 38a on rod 37. Rotation of shaft 33 rocks the rod 37. A link 40 fast with the rod returns the pin carriage to its initial position. Repeat key.-Operation of a repeat key 43 moves the rod 37 against spring 42 to disengage follower 38a from the cam 39, whereby the pin carriage remains in its operative position and the shaft 33 continues to rotate for as long as the operating key remains depressed. Crowding locks.-An extension 50d on lever 50 co-operates with an inverted T-shaped notch in the bar 17, so that simultaneous operation of one of the digit keys and the operating key is prevented.

Abstract: 1454355 Extruding boxed concrete slabs SPIROLL CORP Ltd 12 Feb 1975 [29 Jan 1974] 04038/74 Heading B5A A concrete slab 36, Fig. 6, having a plurality of parallel longitudinal bores 37, is extruded onto a pallet 35 from the open downstream end of a compaction chamber 32, of a machine which extrudes as it is driven, on wheels 38, along rails by the compaction of concrete within the chamber 32 by a plurality of vibrated augers 11, 12, having downstream mandrel portions 38 defining the bores 37. The chamber 32 is defined between side frame members 10, Fig. 1, and the augers 11, 12 are mounted at their upstream ends in bearing housings 16, carried by a single beam 13 through which the vibrations are transmitted to the augers 11, 12, from vibrators 27 carried by the beam 13 which is supported at resilient means, at each of its ends on a frame member 10. The arrangement enables the production of beams of six inches thickness or less, e.g. 4 inches, where the vibrators cannot be carried within the augers. The augers are each rotated from a drive sprocket 30, by drive means carried by a base plate extending between the machine side frame members 10. In the Fig. 5 embodiment (not shown), a pair of vertically acting vibrators (27) are each carried on shafts (28) extending upstream from the beam 13 comprising top, and upstream and downstream plates (14, 15) and the beam is carried on the frame members 10 at each side of the machine on a sleeve 21, Fig. 4, which, via resilient bushings 20, is carried on a spindle 19. At one end each spindle 19 is supported by the base-plate 18 fixed to the frame side member and carrying the drive means, and at the other end is supported by a block 24 which is secured to a block 23 fixed to the frame side member by bolts 25, 26 permitting vertical adjustment of the beam 13. In the Figs. 6 and 8 embodiment, the vibrators 27A are carried on top of the beam 13, which, at each side of the machine, is welded to a support bracket 41 extending longitudinally of the machine frame side member 10, and carried by the member 10 at a resilient pad 45 and vibration free nuts and bolts 46. The threads of the augers on one side of the machine are of opposite hand to those on the other side, Fig. 1 (not shown), and each auger is shrouded from the other. The compaction chamber comprises side plates, and upper hammering and trowelling plates 33, 34, Fig. 6.

Title: Improvements relating to asphalt compositions
IPC: C08L95/00
Filed: 1931-02-10
Abstract: An asphalt composition is made by compounding natural or artificial bitumen with spent material which has been employed in decolorizing or purifying oil.  Examples of materials are fuller's earth, charcoal, florida earth, acid-treated or acid-activated clays, and "gels" used for cleaning oils.  In addition, material used to purify oil which has been subjected to acid treatment and which contains calcium sulphate, free lime and moisture may be used.  The compounding material contains adsorbed oil, mechanically retained oil, wax, fat, and the like, and acts as a fluxing agent, thus enabling hard bitumens to be used.  In an example 13 parts of hard bitumen are heated to 350 DEG  F. and spent earth containing 30-35 per cent oily matter is added.  40 parts of fine limestone flour and 40 parts of coarse limestone flour is stirred in, the temperature being raised to 450 DEG  F., and mixture moulded.  In a second example an asphalt paving containing 45 parts medium grade sand, 45 parts 1/4 -1 inch stone aggregate and 10 parts oily filler together with sufficient bitumen to make the total bitumen content up to 10 per cent is described.

Abstract: 880,711. A.C. generators. KOBER, W. Feb. 10, 1958, No. 4231/58. Class 35. The planar air-gap of an A.C. generator is automatically adjusted in length to give constant output voltage irrespective of changes in load, speed or power factor. As shown in Fig. 6 for a permanent magnet generator, the machine is adjusted for load by mounting the stator on pins 8 riding in helical slots 9 against spring- restraint 14, so that the load torque closes the air gap. Modifications are described in which the stator is carried on a screw thread or on pivoted links, or rides on axial cam surfaces against spring pressure. Fig. 13 shows an additional arrangement in which the rotor 3 is axially adjusted on flexure discs 25 under the influence of fly-balls 26 to provide speed compensation. It is described how the torque and speed compensation motions can be built into the rotor, and the stator may be manually adjustable to set the initial voltage value, or electromagnetic means (Fig. 16 not shown) may be employed to give power-factor compensation. Specification 786,541 is referred to.
