Filed: 1939-06-14
Abstract: 529,965. Line-markers for roads &c. MANLEY, J. E. June 14, 1939, No. 17345. [Class 132 (ii)] In a machine for spraying a line upon a road or other surface, the spray is bounded within an area defined on each of its two longitudinal sides by a flexible traversable belt in contact with the surface to be marked. The machine may be manually propelled or attached to a motor vehicle by a spindle 5 and links 4. Paint and air are supplied to one or more spray nozzles 15 through pipes 19, 20, and the paint is sprayed into the area between two endless belts 13 passing round grooved wheels 10 and spaced apart to an adjustable extent to define the width of the line. The two side frames 8 to which the belt pulleys are attached have independent pivotal movement to enable the belts to maintain true contact with the road. When an intermittent line is to be marked the belts are connected by transverse shields 14, 29 to confine the spray, and strikers 24, 28 are attached to one belt so that, as the machine moves forward, the strikers push up spraystarting rods 21 and spray-stopping rods 25 so that short lines defined by the shields 14, 29 and the inner edges of the belts are marked on the road. The spray nozzles are mounted to permit universal adjustment thereof and may be used independently. The road may be cleaned in advance of the spray by an air jet 30a or by a brush. Side shields may be incorporated in the framework to confine the spray to the area within the two belts.

Title: Improvements in road traffic control systems
IPC: G08G1/082
Filed: 1937-07-22
Abstract: 504,552. Road signals for controlling traffic. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and TYACK, F. G. July 22, 1937, No. 17367. Addition to 450,602. [Class 118 (ii)] In a progressive system of the type described in the parent Specification, wherein the master controller transmits pulses to each local controller to initiate a prevent period followed by a privilege period, these periods are both terminated by pulses from the master controller whereby the necessity for a timer or stepping switch at each local controller is avoided. The local controllers are similar to that described in Specification 501,191. Specification 408,706 also is referred to. Local controller. Upon the receipt of a positive pulse to initiate the prevent period on road A, relays PA, PRE, PJ pull up in turn, relay VA falling away at the end of the pulse, while relay PK locks in series with PJ. If right of way is on road A, demands from road B are stored by locking up relay DE, but the speed timer circuit, is not completed as relays PM, PJ are operated. If right of way is on road B, relays RC, LC will be operated and PM de-energized, demands from road A being effective to complete the Speed Timer circuit, but right of way may remain on road B if there is a stream of traffic causing extensions. A negative pulse terminates the prevent period causing relay PRV to lockup and releasing PRE. If right of way is not already on road A, when PRF releases, a rapid discharge circuit for the Maximum Screen Timor is completed or prepared according as to whether a demand from road A has been made prior to, or during the privilege period so that right-of-way will pass to the A road either immediately or as soon as a demand is made. The second negative pulse causes VA to lock up and PRV to release, whereby the Speed Timer circuit is restored and the controller operates as an isolated controller. In order to give the corresponding periods to road B, relays PRE, PRV and VA are operated and released in a similar manner, but upon the receipt of the third negative pulse, since VA is slow to release, it causes PJ and PK to release in turn, the release of these latter relays causing the controller to i give preference to the B road. Master controller. Upon neon tube N flashing, relays P, PMA, M, B operate in turn, magnet CSD stepping on wipers W1, W2 when PMA releases. Upon the wiper reaching contact 2, a positive pulse is sent to the first intersection during the release period of B. The wipers are stepped on in this manner and when a contact is reached connected to a coil of relays AB-1, BC-1 a negative pulse from condenser QE is sent during the release of B. The one positive pulse ensures the synchronization of all the controllers. The rate of progression is varied by altering the rate of flashing of tube N. This may be performed manually by varying wiper W3 or by using a traffic integrator as described in the parent Specification.

Title: Improvements in Arrangements for Eliminating Fixed Echoes
IPC: G01S13/528
Filed: 1968-04-10
Abstract: 1,198,555. Pulse radar. THOMSON CSF. 10 April, 1968 [21 April, 1967], No. 17381/68. Heading H4D. In a pulsed radar system with wobbulated pulse repetition frequency, a supplemental modulation is applied either at the transmitter or the receiver and this is arranged so that at least the sideband nearest the central frequency of the spectrum of a received echo and comprising the first line is substantially cancelled. As described, a transmitter 1 comprises two oscillators 11, 12 with frequencies F/m and F I /m, respectively, where F I  is the intermediate frequency of an associated receiver. The outputs of the oscillators are combined in a singlesideband mixer 13 and are raised in frequency to (F +F 1 ) in a multiplier 14. A pulse modulator 16 under the control of a timer 2 pulses the output of the multiplier 14 and imposes a predetermined wobbulation upon the pulse repetition frequency. Output from the modulator 16 is taken via an H.F. amplifier 15 and a duplexer 3 to an aerial An. Echo signals are received on the aerial An at a frequency (F + F 1 ) from a fixed target and at a frequency (F+FI+fD) from a moving target, where f D  is the Doppler frequency. The signals are heterodyned in a single sideband mixer 41 with signals from the transmitter oscillator 11, which are raised in frequency to F in a multiplier 42, and output at frequencies F I  and (F I +f D ) is fed through an amplifier 43 to an amplitude modulator 5, for example a variable gain amplifier, which is controlled by the timer 2. Output from the modulator 5 for each echo signal is characterized by the substantial cancellation of a portion of the spectrum on each side of the central frequency F I  or (F I +f D ). This output is fed to a set of paralleled switches 61, &c., which are operated sequentially by the timer 2. Each switch is associated with two band-pass filters 611, 612, &c., in parallel, having the same band-widths, connected to envelope detectors 711, 712, &c., with outputs paralleled to low-pass filters 81 &c. The central frequency of the band-pass filters 611, 612 &c. is such that the low-pass filters 81 &c. receive signals due to moving targets but not those due to fixed targets. The outputs of the said filters are connected directly to a panoramic indicator 9, controlled by the timer 2. In a second embodiment, the amplitude modulator following the receiver intermediate frequency amplifier is omitted, and supplemental phase modulation is effected by means of a phase modulator which is controlled by the timer and is located in the lead feeding power at the frequency F to the single-side-band mixer for heterodyning with received signals at frequencies (F+F I ) and (F+FI+fD) (Fig. 2, not shown). In a third embodiment, supplemental modulation is effected at the transmitter by a modulator, controlled by the timer, which is placed between the pulse modulator and the H.F. amplifier (Fig. 3, not shown). Phase modulation is preferably used.

Filed: 1929-06-06
Abstract: 313,096. Budd Manufacturing Co., E. G., (Assignees of Ragsdale, E. J. W.). June 6, 1928, [Convention date]. 'Cased forms; dies. -Dies particularly those for drawing down articles of large size from sheet metal are produced by coating a complemental shape to form a shell which is then filled with backing material. In the case of a die to coact with a punch corresponding to 10, Fig. 1, the complemental form is extended as at 21 to produce the whole of the die block required. One method of producing the coating is by spraying, for example by the process described in Specification 5712/10, and during this process anchoring members 16, Fig. 3, for the backing may be introduced. Cores 27 may be employed to form bolt holes for attaching the die to the press and these holes and other parts of the die such as 29, Fig. 10, may be reinforced by hard metal inserts applied to the form before spraying commences. Bolts 18 may be incorporated in the backing which is preferably cast into the shell. To reduce risk of distortion the backing may be subdivided by compressible partitions which are removed after setting, the spaces 17 being afterwards filled up. The metal sprayed may be, for example, iron, nickel, steel, copper, brass, nickel-chromium, or other alloy; the complemental shapes may be of wood, plaster, paraffin wax, etc.; and the backing material may be cement, resin, rubber, metal, or alloy, &c. The shape may be coated to facilitate removal of the sprayed-on shell as by graphite, bees wax, &c. The shell may be formed by initially spraying a metal that will have a lubricating action during stamping, for example, copper or a metal resistant to wear such as nickel or chromium or alloys of these with steel the remainder of the spraying being carried out with other metal. The shell may be completed by a backing plate 21, Fig. 10. Other modifications too numerous to abridge are indicated in the Specification.

Abstract: 809,665. Oil burners. BORJESSON, W. A. N., and BORJESSON, G. W. A. June 6, 1956, No. 17451/56. Class 75(1): A means for controlling the intake of air to an oil burner by means of a butterfly valve in a funnel-shaped air duct 4 connected to the intake side of the blower casing comprises a two armed lever 7 on the axis 6 of the valve, one arm of which is secured to a tension spring 8 anchored at the other end to the air duct casing and the other arm is disposed so as to be operated by the head 9 of a piston moving in a cylinder 11 connected to the oil pump 2 of the burner. Operation of the oil pump causes the piston to move outwards, opening the valve against the tension of the spring 8. The movement of the lever 7 may be controlled by an adjustable stop 18. Oil from the pump passes to the burner nozzle by a pipe 13. In a modification, the pipe 13 leads from the cylinder 11 so that the oil pressure operates the piston and hence the valve before the oil reaches the burner nozzle.
