Title: Improved means for use in checking the timing of the ignition in an internal combustion engine
IPC: F02P17/02
Filed: 1947-02-21
Abstract: 621,353. Testing ignition. AUSTIN MOTOR CO., Ltd., WEAVING, J. H., and HIGHFIELD, F. W. W. Feb. 21, 1947, Nos. 5078 and 16727. [Class 7 (iv)] The invention relates to means for checking the ignition timing of internal combustion engines whereby each time the contact breaker points of the ignition system open in respect of any plug or in respect of a selected plug the voltage generated by a transformer energised as a result of the breaking of the contact breaker points is utilised to trip or control a flash of an electronic flash tube energised from a separate source of electric power, thus forming a stroboscopic device. A low tension ignition circuit consisting of battery B, contact breaker points A with a shunted condenser H, has a transformer C with two primary windings c, d connected therein. Upon each operation of the circuit breaker points A the winding c supplies impulses through a distributor, to the sparking plugs, whilst the winding d triggers an electronic flash lamp F, that is connected in parallel with a condenser G, to a high tension direct current source. The resulting flash illuminates a mark on the engine flywheel and by a stroboscopic action' enables the crank shaft angle at the moment of ignition to be read on a fixed scale. In a modification, Fig. 2, the timing of any particular plug may be ascertained by inserting in the plug lead the primary of a loose-coupled transformer J. When the plug receives an impulse it is reflected into the secondary of the transformer J and by momentarily increasing the grid voltage of a triode M connected in series with a transformer primary d across a high tension direct current source, the latter having a condenser T in parallel, causes the triode M to conduct and so supply an impulse to the transformer primary d, the secondary winding being connected to a circuit identical to the flash tube circuit in Fig. 1. In another modification for an engine which is being " motored the low tension circuit is similar to Fig. 1 except that primary winding c is dispensed with. If it is desired to check the crank shaft angle at which any particular plug would have fired, the flash tube " trigger " lead is taken through one contact of a distributer. The second Provisional Specification states that the flash tube may be dispensed with and the triode may be of the type which gives illumination when " triggered."

A roller straightening machine for elongate metallic structural members has a plurality of rotatable driven shafts arranged parallel to each other in a housing, each shaft carrying a pair of straightening tools each of which has a surface adapted to engage a distinct portion of a member to be straightened, to apply a force thereto sufficient to contribute to the straightening thereof and at least one of the shafts having power means associated with one of the tools thereon to axially adjust the position of the tool relative to the shaft. The machine has a number of upper shafts and a number of lower shafts in staggered arrangement, each shaft 23 carrying a pair of rollers 21, 22 and being supported in bearings 25, 26. The roller 22 is fixed directly on the shaft and the roller 21 rotates with the shaft because it is keyed to a sleeve 37 which is itself keyed to the shaft and which telescopes over the end of the shaft and is secured to one end of a rod 38 which passes through a central bore 41 through the shaft. The other end of the rod is attached to the piston 42 of a double acting hydraulic cylinder 44 which is mounted on the end of, and rotates with, the shaft 23. Opposite ends of the cylinder receive pressure fluid through pipes 45, 48 and a rotating joint 46. The piston moves the roller 21 so that the width between the rollers is such that each of the rollers engages a flange and the central web of an I-section beam which is to be straightened. An extension of the rod 38 passes through the rotating joint 46 and is connected to the lever arm 52 of a potentiometer 53. The potentiometer controls an indicator which shows the width to which the rollers 21 and 22 are set.

Abstract: 1,081,801. Measuring weight electrically; weighing apparatus. GIRLING Ltd. Feb.28, 1964 [March 6, 1963], No. 5151/63. Headings G1N and G1W. In a batch weighing apparatus of the type in which the flow of granular, powdered, or liquid material from a feeder 2, Fig. 1, is shut off by a gate 3 when the output from a load cell 4 equals a voltage preset by dials 7 (in known manner), a further voltage is introduced to advance the time of shut-off, by an amount depending upon the preset weight in order to allow for the weight of the material still falling between the gate and the hopper. The dials 7, in addition to presetting a voltage corresponding to the required weight, operate switches S1 S2 and S3, Fig.2, which apply a voltage, indicated at S3, to any one of the twenty positions on a uniselector U1, the transistorcontrolled wiper of which is mechanically coupled to the wiper of a switch U2. The switch U2 connects an appropriate secondary tapping of a transformer TR via a variable resistor VR, to a potential divider R1 R2 the output P being added to the load cell output 4 (Fig. 1). VR is adjusted in accordance with the density of the material, and the arrangement is such that the voltage on the selected tapping is large for a small preset weight (7), and vice versa since the more material there is in the hopper, the shorter is the column of material still falling from the gate. The required weight information may be fed into the apparatus by means of punched cards, or tape; and the entire apparatus may be mechanical instead of electrical.
