Title: Improvements relating to the cutting of extruded explosive material into pieces
IPC: A47H1/19
Filed: 1945-07-30
Abstract: 599,836. Cutting extruded bars of explosive material. DU PONT DE NEMOURS & CO., E. I. July 30, 1945, No. 19498. Convention date, Aug. 12, 1943. [Class 87 (ii)] A bar of explosive material is extruded from a nozzle 3 and impinges on a sheet of paper 1 lying on a shelf 2. The paper is fed by means of a driven roller 4, and its forward movement is aided by the friction between the bar and the paper. The paper is drawn from a supply spool 8 by way of a metering roller 10. This roller carries a cam 12 which, twice every revolution thereof, depresses a rod 16 and allows a single revolution friction clutch 22 to drive a shaft 26. The shaft 26, through a Geneva movement 27 drives a shaft 28 carrying a cutter wheel 30 having radial cutter elements 29. These elements cut pieces off the bar, and the pieces are wrapped in the paper by a device 38. The paper may not be used as a wrapping, in which case it may be replaced by other sheet material. The cutter wheel may have no rim.

Title: Windshield wiper blade connectors
IPC: B60S1/40
Filed: 1947-07-21
Abstract: 655,259. Windscreen-cleaners. PRODUCTIVE INVENTIONS, Inc. July 21, 1947, No. 19501. Convention date. Feb. 22. 1944 [Class 138(i)] In a connector assembly for detachably interconnecting a windshield-wiper arm and a windshield-wiper blade co-operating connector means on each of the wiper members are adapted to be locked in pivoted connection with each other by means of a member spring urged to a locking position and movable to an unlocking position in which the wiper members are rendered freely separable, and a separate handle is provided operatively associated and having a lost motion connection with the locking member. A connector member 3, having a base 4 and side walls 5 between which is fixed a transverse pin 6, is rigidly fitted on the outer end of a wiper arm 1. A cooperating connector means 11, Fig. 2, in the form of a U-shaped clip having a base 12, side walls 13 and provided with a transverse slot 16 to receive the pin 6, is permanently fixed to the frame 14 of the wiper blade. A locking member 17 is slidably fitted, inside the clip 11 and is urged to the locking position shown in Fig. 1, by a spring 22. The member 17 is substantially broad enough to extend across the space between the side walls 13 of the clip, but the tripping arm 20, locking arm 18 and their connecting portion 19 are narrower than the rest of the member from shoulders 20a. A locking handle 25, has sides 27 connected by a cross portion 26, and has a lost motion to the left of the locking member 17, Fig. 2, so that it can be returned to a normal position when the locking member is in the unlocked position, its movement being unhindered since the shoulders 20a are too far removed to the left. In the locked position shown in Fig. 1, the cross portion 26 is slightly canted with respect to the portion 19 so that the line of pull of the handle is located above the axial line of thrust of the spring 22 on the member 17. As the handle is pulled to the right, Fig. 1, the member 17 tends to pivot in a clockwise direction but is prevented from so doing until a nose portion 21 of the member 17 passes a downwardly turned ear 31 on the base 12 of the clip. On passing the ear the nose is snapped upwardly so as to be detained by the end 32 of the ear as shown in Fig. 2. The nose is tripped from the detaining portion by the pin 6 engaging the tripping arm 20. In a modification the shoulders 20a are provided near the connecting portion 19 so as to prevent the handle 25 having a lost motion to the left when in the unlocked position. Any thrust on the handle will be transmitted through the shoulders and thus no damage to the locking member 17 can occur. Specifications 644,048, 650,311, 655,260 and 655,261 are referred to.

A heat-exchanger such as an economizer, superheater or evaporator, has longitudinallygrooved tubes coiled in coaxial helices, Fig. 5, the pitch of the helices being varied by movement of a support 27 on a tie-rod 25 (bearing a deflector core 24) so that the angle of fluid-flow to groove, and therefore the heat-exchange rate, can be varied. The tubes may be arranged in parallel layers which may be staggered, Fig. 3 (not shown). A heat-exchanger may have a mixture of finned and finless tubes. In Fig. 4, the tubes 13, over which a fluid flows transversely, have longitudinal grooves 16, which may vary in depth and width according to their position on the tubes or on longitudinal fins 14 which may be provided. The fins may be tangential, as shown, or diametral and they may be hollow. The whole surface of a tube or fin need not be grooved. The grooves may be of rectangular, triangular or trapezoidal section and separated by a rounded ridge. The depth is about 1 millimetre. There may be transverse grooves also, producing a checkered pattern, and there may be internal grooves. The tubes may be of circular, oval or square section.

Filed: 1951-08-22
Abstract: 702,351. Pulse code modulation circuits; non- linear circuits. GENERAL ELECTRIC CO., Ltd., and BARRY, J. N. Aug. 22, 1952 [Aug. 22, 1951], No. 19803/51. Classes 40 (5) and 40 (6) Apparatus for quantizing an electrical signal comprises a plurality of electric valves 7 ... 13 which each have a control electrode and which are arranged with a common load 17 and a common input circuit to all the control electrodes, so that as the signal varies over a range of levels one of the valves becomes conducting or ceases to conduct at each quantizing level and the quantized output signal changes level in a series of steps. The quantizing levels which may be equally spaced, are determined by cathode bias derived from potential dividers 21 ... 26 each of which includes a variable resistor 38. The cathodes are decoupled by condensers 28. The input signal is fed to the valves through a cathode-follower stage 4, and the output signal is reversed in polarity by an amplifier 31. In a pulse code modulation system, the quantized signal is supplied to a coder which may be of the type described on pages 30-36 of Volume 27 of the Bell System Technical Journal. The input signal may alternatively be a received video signal, the quantized output being fed to a cathode ray tube so that the picture level changes in discrete steps. In this connection, Specification 702,352, [Group XL (b)], is referred to.

Each vane 14 is pivotally attached by a ball-and-socket joint 21 to a respective thrust member 22 which is in turn pivotally connected by a further ball-andsocket joint 23 to a disc 24 rotatable about an axis ZZ intersecting axis XX and inclined thereto. The common pivot axis AA of the ball-and-socket joints 23 is inclined at an angle other than 90 degrees to axes 16. Each chamber 5, 6 has a recess 27 with a fuel/air mixture port 29 and a sparking plug 28. The housing 1 is rotatable on a shaft 4 which is stationary and has a branch portion 50 which leads into a cylindrical chamber 30 in the housing. Portion 50 serves to lead the air/fuel mixture to the recesses 27 via ports 29, shaft 4 and portion 50 both being hollow for the passage of the mixture. Thus as housing 1 rotates, portion 50 comes into communication with the ports 29 alternately. In operation, starting from the position shown, plug 28 sparks off the mixture just compressed by the respective vane 14 in chamber 6 to thrust out this vane. The vane of chamber 5 has left the chamber and the products of a previous combustion are exhausted. The vane of chamber 6 then undergoes its power stroke and, due to the inclination of axis AA relative to the axis 16 of the vane, causes rotation of disc 24 and housing 1. Meanwhile vane 14 of chamber 5 has moved inwards to compress fuel mixture in the chamber and the situation is the reverse of that shown in Fig. 1. Alternate power strokes of the vanes serves to continuously rotate the disc: 24 and housing 1. In further embodiments, exhaust ports may be provided in closed working chambers, the vanes may be provided by a single circular disc pivoted about a diameter thereof and alternative forms of coupling between the vanes and output member are also described Figs. 3-6 (not shown). There may also be only one ignition means, the charge being compressed in one chamber and then passed to the other just prior to ignition Fig. 5.

Abstract: 755,375. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 20, 1955 [July 15, 1954], No. 20674/54. Class 40 (3). In apparatus for examining or effecting a measurement of a composite electrical wave, such as a television test signal, Fig. 1a, comprising a sine wave A interrupted by line synchronizing pulses B, the wave is combined with a pulse wave, Fig. 1b, to produce a resultant signal, Fig. 1c, exhibiting a peak-to-peak value equal to the sum of the sine wave and pulse wave and independent of the synchronizing pulses B. The pulse wave is made equal to or a harmonic of the line synchronizing frequency, and each pulse is made wider than a synchronizing pulse. Each pulse is also of an amplitude a little more than the negative peak of sine wave and the negative peak of the synchronizing pulses. In Fig. 2, the composite wave is applied at 1 and the pulse wave at 4 whereby the combined wave is developed across the common anode load 7 and 8 of valves 3 and 6. The wave is then applied to a conventional peak-to-peak rectifier circuit 10-15 and the output applied via terminals 16 to a meter or oscilloscope. Reference is made to the use of a wave in which the sine wave is controlled so as to be varied or changed from time to time over a range of frequencies.
