Title: A motor vehicle with all-wheel drive and with a distribution gear in addition to the conventional change speed gear
IPC: B60K17/34
Filed: 1947-12-15
Abstract: 656,242. Motor vehicle driving gear. MOTOR CAR WORKS, NATIONAL CORPORATION. Dec. 15, 1947, No. 33039. Convention date, Feb. 28, 1944. [Class 79 (ii)] [Also in Group XXIV] In addition to the usual change speed gear in a motor vehicle a two-speed distribution gear is provided for distributing the power to the front wheels and to the rear wheels and a free wheel device operating through the wedging action of locking members, such as rollers, is interposed in the drive to the front wheels to disconnect the drive thereto when the front wheels overrun.

Abstract: 939,299. Holders for cutting blades; planes. F. PARRAMORE & SONS (1924) Ltd. Sept. 11, 1962 [Sept. 15, 1961], No. 33098/61. Class 61. A holder for a file- or rasp-like cutting blade as used for cutting wood &c. with a plane-like or file-like action comprises an elongated box 8 with an open bottom having means for holding the blade in tension along the open bottom and having projections near the ends of the upper surface of the box whereby the holder is held to the under surface of a plane. The projections provide undercuts directed each towards the other, one of the projections being movable towards the other. The fixed projection comprises two pegs 12 with undercut heads, the pegs being pressed into holes in lengthwise shoulders in the upper corners of the box 8. In a modification, the projections comprise two undercut lugs integral with the holder. The end 6 of the plane is chamfered whereby to engage in the undercuts provided by the heads of the pegs 12 or undercut lugs. The movable projection comprises the pointed end 24 of a screw 23 the latter being threaded through an upwardly extending lug 22 on the holder 8. The screw when advanced enters a countersunk hole in the end 7 of the plane, the lower side of the point 24 constituting an undercut. The blade 11 is held to the lower end of the box 8 by pins 18 having flat undercut heads, one pin being pressed into the holder itself and the other being pressed into a block 15 which slides on the edges of the sides 9 of the box and is moved by turning a screw 17. In a modification, Fig. 6 (not shown), a blade having inturned hooks at its ends is provided. The sides of the holder are slotted at 26 for the escape of shavings. A notch 28 is provided in the upper edge of the holder to accommodate the blade 3 of the plane.

Title: Improvements in or relating to radio receiving circuits
IPC: H03G3/28
Filed: 1948-12-29
Abstract: 648,235. Automatic noise suppression. WESTERN ELECTRIC CO., Inc. Dec. 29 1948, No. 33396. Convention date, Dec. 30, 1947. [Class 40 (v)] In a radio receiver, noise occurring in the output from the detector in the absence of an adequate signal is selected by means of a circuit tuned to a frequency outside the useful audio range and is applied to an amplifier having an output circuit tuned to a harmonic frequency and feeding a rectifier from which muting voltages are applied to an audio stage of the receiver. As applied to a frequency-modulation receiver, a branch amplifier 17 is fed from the discriminator 12 over a condenser 20 and a circuit 28, 29, 34 tuned to a frequency above the audio range, and is neutralized by means of a condenser 35. The output circuit 21, 22 is tuned to the second harmonic of the input frequency and feeds a rectifier 18 from which rectified noise voltages are applied, over a filter network 25 to bias back the audio amplifier 15. The valve 17 is biassed to act as a harmonic generator by means of a cathode resistance 30 and resistance 37 connected to the positive supply, but is over-biassed by an adequate signal due to the negative voltage developed on the grid of the limiter 11 and which is applied to its grid over a filter network 31 ; in this way a sharp muting action is obtained. The arrangement may also be applied to an amplitude modulation receiver, noise being derived from the detector output and the control bias for the grid of the valve 17 being taken from the A.V.C. line. U.S.A. Specification 2,343,115 is referred to.

[Class 40 (iv)] In a system in which the selectors are controlled from the register by comparison of potentials, a selector meeting a busy condition is directed to a normal or other unwired position so that its subsequent release does not disturb the existing condition. As shown for a final selector EK, relay SR (not shown) in the register grounds the a wire to operate relay X which prepares a circuit for switching relay Y in series with itself. The selector is set in known manner by magnet K under the control of tens and unit switches MSX, MSI and a zero potential switch NW in theregister, the wanted line being tested by a device BT. If it is idle, the removal of ground from the a wire energizes switching relay Y. If it is busy, however, a fresh control potential Vb is made effective over wire BM and the selector drives to a busy position marked by this potential in bank e. The momentary operation of relay Y upon release therefore produces no disturbing effect. Resistances in the circuit are denoted by the reference W.
