Filed: 1936-07-01
Abstract: 463,680. Controlling vehicles. RENAULT, L. July 1, 1936, No. 18276. Convention date, July 10, 1935. [Class 79 (v)] [Also in Group XXXIV] Failure of the driver through illness or other cause to actuate periodically a lever or the like, results consecutively in the operation of a signal, the disengagement of the driving means and the application of the brakes. A chamber 1 provided with an adjustable leak 2 is connected to a reservoir 16 by a cock 17 with the hand lever 19 in the position shown. If the pressure falls sufficiently a piston 6 is depressed by a spring 7 so as to cause a switch arm 9 to engage successively contacts 12, 13, 14 thus operating a whistle or other signal, disengaging the driving mechanism and applying the brakes. To prevent this the driver must move the lever temporarily to a position such that the reservoir 16 is connected by a pipe 18 to a compressed air supply, the reservoir 1 being however then isolated. To prevent the device from being effective during stoppages of the vehicle a centrifugal governor 22 driven from the wheels is arranged to break the circuit of the device at 21 when the vehicle is not running.

Title: Motion pictures and the like with synchronized odor emission
IPC: G03B29/00
Filed: 1955-06-24
Abstract: 807,615. Odour-emitting devices synchronized with motion pictures. LAUBE, H., and GOOD, B. S. June 24, 1955 [June 24, 1954], No. 18349/55. Class 81 (1). [Also in Group XX] A device for the emission of odours in synchronism with motion pictures, television, advertizing illustrations, &c., comprises an arrangement wherein one of a battery of odour-containing cells 10, is brought into register with a conduit 40 in response to a signal, whereafter the odour is carried into the conduit and released into an area through the conduits 65 in synchronism with visual images. The signal corresponding to a particular odour is carried by, e.g., a film strip 81 and produces an electric impulse which closes relayoperated switch 95 to start a motor 20. Rotation of the motor shaft 17 immediately opens rotary switch 101, 102 whereby another relayoperated switch 105 closes, so that the motor shaft traverses 360 degrees before it is stopped by the closing of switch 101, 102. Rotation of the motor shaft causes an arm 16 to engage a segment 15 on a platform 11 which is thus rotated so that an adjacent cell outlet 25d is brought into register with conduit 40. At this point switch arm 101 contacts segment 108 to operate a pick-up nozzle solenoid 55 which presses conduit 40 into engagement with the cell outlet. The latter is normally closed by a spring-urged valve which is opened by the engagement of the conduit. In a modification, the cell outlets are arranged spirally in the cannister, and the necessary radial movement of the conduit 40 is effected by a cam device operated by the motor shaft. Air may be passed through the cells by a suction pump 51 as shown, or by a blower. A diaphragm pump is also shown. The cells contain either odouremitting materials from which the fixatives have been removed, or odour neutralizing materials such as benzaldehyde, hydroquinonedimethyl ether, tridecylaldehyde, amylsalicylate, methylnonylacetaldehyde and methyl heptanones in solvents such as glyceryl acetates, ethyl phthalate or ethyl alcohol. The device may also contain a heating element to heat the vapours prior to removal through conduit 40.

Title: Improvements relating to relay devices for use in automatic telephone systems
IPC: H04Q3/42
Filed: 1923-07-16
Abstract: 221,316. Siemens Bros. & Co., Ltd., and Humphries, H. E. July 16, 1923. Order apparatus.-In a relay chain in which relays are energized one by one in response to impulses to mark circuits or make circuit changes, when a relay is energized, the next succeeding relay becomes connected up, but is short-circuited over the impulse - contact until this changes over at the - next impulse. Figs. 1 and 3 show an arrangement in which the impulse contact k causes battery and earth to be - connected in turn over the lead l to the relays A, B, C which are connected alternately to earth and battery. At the first closure of contact k relay P energizes over winding 1 and locks in - series with winding 1 of relay Q which is short-circuited until contact k opens, and then operates. At the next closure of contact k relay Q locks over winding 2, while winding 2 of relay P is connected up in opposition to winding 1, so that this relay relapses. Relay Q falls back when contact k opens, and the operation is then repeated. The operating lead l is thus connected over contact p<3> alternately to battery and earth. At the first impulse, relay A energizes, lacks, connects up lamp L<1> and connects lead l to relay B, which is shortcircuited until lead l is earthed at the next impulse, when it energizes, locks, connects up lamp L<2> in place of lamp L<1> and connects lead l to relay C. Modifications of this arrangement are described in which each relay cuts out the preceding one. The operating lead l may alternatively be connected up over a line switch having alternate contacts connected to battery and earth. Fig. 7 shows an arrangement in which a relay is energized at the opening of impulse contact k<1> and the succeeding relay is connected up by the release of the preceding relay at the next closure of contact k<1>, but is short-circuited over this contact. The first closure of contact k<1> energizes start relay A, which connects up winding 1 of relay B, which is short-circuited until contact k<1> opens. Relay B then operates and locks over both windings in series with relay A. At the next closure of contact k<1>, relay A is short-circuited and releases, and relay B remains locked over winding 2. Winding 1 of relay C is thus connected up, but is short-circuited until the subsequent opening of contacts k'. Each relay controls one of a set of lamps L', L<2>. In a modification of this arrangement suitable for rapid impulsing, each relay is provided with a third releasing winding which opposes the holding winding. The use of a start relay is also obviated.

[Also in Group XXXI] The driving motor or engine 6, gearing 7 driving the rear axle 5, and the rear axle itself, form a unit separable from the travelling chassis 3 of a mobile slewing jib crane the motions of which are also driven through take-offs 10, 11 from the gearing 7. In the form illustrated the removable driving and rear axle unit is provided with side members 7<SP>1</SP> adapted to slide into guides 8 on the travelling chassis to be secured by straps (not shown). The slewing and hoisting mechanisms are driven through a pair of corresponding reversing gears 14 which together -form a unit mounted by means of slides 18, 19 for removal in a downward direction from the travelling chassis. The reversing gearing 14 may alternatively be driven from a common take-off. The slewing gear operates a pinion 15 which engages inside the usual slewing ring 2. The hoisting gear is connected by splined shafts 16, 17 to drive the winding drums for the hoisting and luffing cables and for a cable controlling operation of a grab. Control of the gearing is effected from the cab 1 by compressed air conduits led through bores in the shafts 16, 17 or connected by rotary couplings surrounding these shafts, or the control may be effected by mechanical, hydraulic or electrical transmission. Several interchangeable power units may be provided for attachment to the travelling chassis so that the crane may alternatively be provided with a petrol engine, a diesel engine or an electric motor. The front axle 4 of the crane is cranked to permit the crane to be withdrawn rearwardly from over the lowered gear unit 14.

Abstract: 361,311. Looms with automatic weft replenishment. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Crompton & Knowles Loom Works ; Worcester, Massachusetts, U.S.A.) June 18, 1930, No. 18592. [Class 142 (iii).] Shuttle-changing mechanism.-A loom for weaving with two kinds of weft has two drop boxes 30, 31 at one side of the loom and a double transfer box B and a double celled magazine M at the other end, weft exhaustion being indicated in the boxes 30, 31 and change of shuttle effected on the following pick, when the lay is at or near its rear position, the new shuttle coming from one or other cell of the magazine M as determined by the active card of the pattern change mechanism 37 for the drop boxes 30, 31. When either acting shuttle is exhausted the mechanism 37 through the levers 38, 53, rod 52, and switches U, L closes a circuit through one or other of the solenoids 71, 72'and by means of a hook 86, 88 springs one of the levers 83, 84 into line with a cam 91, 92 on the low shaft 93 and thus causes a wire 94 or rod 95 to be pulled. The pulling of the wire 94 turns a shaft 114 to bring a rubber holding pad 123 against the second shuttle in the cell SF of the magazine M and withdraws the finger 116 so that the bottom shuttle in the cell SF falls on to the plate 125, or the pulling of the rod 95 through a lever 140 and plunger 137 pushes the bottom shuttle from the cell SR on to the plate 125. The plate 125 is carried by pivoted arms 127 and kept in normal position by a spring 128, but at shuttle change the box B is lifted, its lid is opened by a lug 167 on it engaging a cam 168 on the magazine, while lugs 172 push back the plate 125 allowing the new shuttle to fall into the upper cell of the box R. The exhausted shuttle enters the lower box 179 and is discharged down a shoot 180 at the next beat-up. Either lever 83, 84 when depressed moves a bell crank 150 and lever 154 to lock a lever 162 to another lever 159 which is oscillated by a cam 160 on the shaft 93 and thus through the rod 164 causes the box B to be lifted, or the lever 162 may be locked to the lever 159 by means of a solenoid in a circuit 80 common to both solenoids 71, 72. The magazine M is of the section shown in Fig. 17, the threads from both front and rear shuttles being secured to the same holder 130.
