Title: Improvements in and relating to windscreen wipers
IPC: B60S1/18
Filed: 1948-08-05
Abstract: 650,090. Windscreen-cleaners. CHIVERS, H. A. Aug. 5, 1948, No. 20723. Convention date, Aug. 7, 1947. [Class 138(i)] [Also in Groups XXIV, XXVI, XXIX and XXXI] Apparatus for operating a windscreenwiper comprises a fluid flywheel device having a driving flywheel 3, Figs. 1 and 4, adapted to be driven from the vehicle engine, and a co-operating driven flywheel 4, means for converting rotary motion of the driven flywheel into the desired motion of the wiper, e.g. by a manually operated clutch, shaft 22, worm 23, worm wheel 24 and flexible drive to an actuating linkage, and means for adjusting the gap between the two flywheels while the apparatus is in operation in order to vary the speed of rotation of the driven flywheel and of the motion of the wiper. In the embodiment shown in Fig 1 the flywheel 3 is fixed to a shaft 2 adapted to be driven from the vehicle engine and the flywheel 4 secured to a coaxial shaft 6 is urged away from the flywheel 3 by a spring 13. The shaft 6 in connected to the shaft 22 by a dog clutch 16, 17. The shaft 22 is formed with the worm 23 which drives the wheel 24. The clutch 16, 17 is engaged by operating a flexible cable connected to an arm 28 which in turning a grooved sleeve 27 engaging a pin 32 on a shaft 33 moves the shaft 33 and a ball connection 34 to move bodily the shaft 22. After engagement of the clutch further movement of the shaft 22 causes the flywheel 4 to move into close proximity to the flywheel 3 against the action of the spring 13. The flywheels enclosed in an oil chamber 7 are provided with cups or pockets 2 and as they are brought close together the speed of the flywheel 4 is increased. The maximum speed of rotation is predetermined by a centrifugal governor 19 comprising a cross bar 26 having a pair of arms pivoted thereto at their inner ends and carrying 'friction pads at their outer ends. to engage the inner periphery of a casing 21 when the speed of rotation of the shaft 22 exceeds a predetermined rate. In the embodiment shown in Fig. 4 the flywheel 4 is urged into close proximity to the driven flywheel 3 by means of a spring 52. The clutch comprises a plate 43 secured to the shaft 6 and a moveable spring urged plate 44. The plates 43, 44 are engaged by bodily moving the shaft 22. As the speed of the driven flywheel increases a governor ring 48 swings towards a perpendicular position and causes a semi-circular shaped.cam 49 to turn moves the clutch and shaft 6 bodily against the urge of the spring 52 to widen the gap between the flywheels. A brake disc 56 adjusted in position by a screw 61 meshing with teeth in the periphery of the plate is engaged by the clutch plate 43 and thus prevents excessive speed of rotation of the driven flywheel.

Title: Improvements in signal pulse discriminator
IPC: H03K5/01
Filed: 1965-05-18
Abstract: 1,107,913. Transistor pulse circuits. GENERAL ELECTRIC CO. 18 May, 1965 [18 May, 1964], No. 21037/65. Heading H3T. Pulses produce an output only if their slope exceeds a given value for a predetermined time. Input signals at terminals 11, 12 (waveforms R and S of the waveform diagrams in Fig. 2, not shown) are passed through a fullwave rectifier 10 to bring them to the same polarity but opposite same at terminals 13 and 14 (waveforms T and U). These pulses pass to a circuit 26 which produces an output pulse which begins only when and if the slope exceeds a given value and terminates when it falls below a further value, i.e. in the region of the peak (waveform W). The leading edge of this pulse starts the generation in 32 of a ramp which continues to the end of the pulse and thus has an amplitude dependant upon the duration the slope is exceeded (waveform X) and this ramp is fed to a coincidence gate which can open only if its input exceeds a given value. The output at 14 from the full-wave rectifier is effective at the other gate terminal only if the signal at 14 exceeds a given value so that the gate produces an output if the input pulse at 11, 12 exceeds a given amplitude and also exceeds a given slope for a predetermined time. The output of the gate is applied to a pulse stretcher 43. In the slope detector 26 (Fig. 3) a negativegoing signal cuts off transistor 74 if its slope exceeds the given value. The right-hand plate receives a charging current from both the emitter and collector of transistor 75 which is now conducting, but when the slope drops below a given value, e.g. at the peak of the signal, the voltage at the right-hand plate rises sufficiently to allow transistor 74 to conduct and thus cause 75 to cut off again. While 75 conducts, 94 is cut off so that a ramp is generated across capacitor 105 and if, simultaneously with the application of a gating signal at 37, the ramp reaches a given level, a transistor 109 conducts. This transistor rapidly charges a capacitor 130 so that when 109 switches off, 124 is cut off and remains so until the capacitor is recharged, producing a delayed and stretched pulse at 44.

Abstract: 936,258. Making electrical components; jointing by stamping. MORGANITE CARBON Ltd. June 12, 1961, No. 21082/61. Classes 83 (2) and 83 (4). [Also in Group XXX] A method of making a carbon strip and carrier electrical contact unit comprises first joining together a carrier bar and a plane blank for the sheet metal channel and then, while the carbon strip is held in place along the middle of the channel blank, folding the borders of the channel blank over and tightly against the sides of the base of the carbon strip by a swaging operation. The base of the carbon strip 2 is metallized by spraying with copper or brass to provide a good electrical contact with the channel 3. The mild steel channel-shaped carrier bar 4 has lateral flanges which are spot welded at 6 to the channel 3. The assembly is passed between opposed swaging rollers which deform the edges of the channel 3 into close engagement with the dovetail base of the carbon strip. In a modification in order to save weight the carbon strip is held only at longitudinal intervals in spaced short channels 7 which are spot welded to the carrier bar 4, Fig. 3. The short channels may be formed from a plane strip blank with notched borders so that the web of the channel is continuous whilst the flanges are divided into longitudinal sections 7.

Title: Improvements in or relating to circuit arrangements for telephone systems having means for storing metering pulses
IPC: H04Q3/00
Filed: 1958-07-01
Abstract: 837,259. Automatic exchange systems. SIEMENS & HALSKE A.G. July 1, 1958 [July 19, 1957], No. 21102/58. Class 40 (4). Metering circuits for accumulating charges during a call each comprise a number of multistable magnetic storage elements and are scanned continuously so as to receive signals indicative of the charges from a common circuit. Each call involves the use of a repeater AUe associated with an intermediate storage device Sp. A common signalling circuit ZM connects with each storage device Sp and associated repeater in turn to enable metering signals from the repeater to be sent to the storage device and accumulated there until the end of the call. When a repeater is taken into use its busying relay C energizes to clear the multi-stable magnetic elements E, Z, H of the storage device Sp. A metering pulse causes Zh to energize so that connector K hunts for the relevant repeater. When the repeater is found test relay P energizes to restore the windings I of saturable transformers SE, SZ, SH. Relay P also energizes AE which falls back after a predetermined time to break the circuit to winding I of SE while making circuit to winding II. A pulse is therefore omitted by winding III to storage element E in circuit Sp. The connector K releases the repeater and continues its scan. Element E stores up to 9 impulses, the tenth energizing JE, so operating AZ and zeroizing E whereby carry is effected to the tens element Z. similarly carry is effected to the hundreds element H by operation of AH.
