Title: Improvements in signalling apparatus for road vehicles
IPC: B60Q1/44
Filed: 1966-03-30
Abstract: 1,104,872. Road traffic signals on vehicles; selective signalling. W. H. BUMPOUS. 30 March, 1966, No. 13980/66. Heading G4H and G4Q. [Also in Division G1] Retardation of a motor vehicle is indicated by an inertia switch controlling a rear light source having a minimum intensity of 500,000 lumens, a maximum illumination time of 30 milliseconds, a total minimum output of 15,000 lumen-seconds, and a start time of less than 20 milliseconds. The flash nature of the signal distinguishes it from other signals, and the short start time allows more time for a following driver to react. The light source may be a photo-flash bulb (Fig. 1, not shown) or a highvoltage discharge tube (Fig. 2, not shown). In another arrangement, Fig. 3, inertia switches 71-78 of successively greater operating points control respective light sources 61-68, of which 61-65 are incandescent lamps and 66- 68 are flash bulbs. If retardation increases in value the lamps 61-65 light up in succession and eventually the bulbs 66-68 flash. An ammeter 80 gives the driver an indication of his deceleration. In a modification, Fig. 4 (not shown), the ammeter is omitted and a pilot lamp (81-85) visible to the driver is connected in parallel with each incandescent lamp 61-65. A test switch (97) by-passes switches 71-75 for test purposes.

Abstract: 1,109,484. Controlling gradation. FUJI SHASHIN FILM KABUSHIKI KAISHA. April 7, 1965 [April 8, 1964], No. 14853/65. Headings G2A and G2C. In photographic printing, in which the density of the printed image depends on the product of the light intensity and the exposure time, the gradation is controlled by varying the exposure time inversely with the intensity so that an image of the desired density and gradation is obtained. The exposure time is from 1 to 0À01 sec., or less. Thus various gradations can be obtained from one kind of printing paper, avoiding the necessity for providing different papers of varying degrees of hardness or softness. Fig. 2 shows a suitable apparatus. A light source 1 is controlled from a power supply 2, and the light passes through a condenser lens 6, negative 7, an objective lens 8 and iris diaphragm 9 to the printing paper 10. Also in the light path are a step wedge 4 and a shutter 3. Wedge 4 controls the light intensity, and shutter 3 the exposure time. These are varied inversely with respect to each other by means of a gradation selector 5, adjusted after inspection of the negative to give the required gradation and density. Alternatively the selector 5 may couple the wedge 4 and power supply 2 to provide inverse variation of intensity and time, in which case the shutter 3 may be omitted.

Title: Improvement in variable load brakes
IPC: B61H13/32
Filed: 1946-05-16
Abstract: 612,057. Brake-operating mechanism for vehicles. SVENSKA AKTIEBOLAGET BROMS-REGULATOR. May 16, 1946, No. 14862. Convention date, May 26, 1945. [Class 103 (i)] Vehicle brake-mechanism of the kind whereby the braking power is automatically varied in dependence upon the loading of the vehicle is so constructed that the braking ratio (that is, the ratio of the total pressure of the brake shoes against the vehicle wheels to the weight of the vehicle) increases with the load throughout the loading range. Since the coefficient of friction decreases with increasing brake shoe pressure, the braking ratio may thus be kept, with varying loading of a vehicle, at a value equally near the limit at which the wheels continue to roll and do not slide. The brake-applying mechanism shown comprises a cylinder 3, lever 2 and linkage 4 connected to the brake shoes 17. Automatic adjustment of the fulcrum 1 of the lever 2 is effected by linkage 10, 7, 9 and a curved leaf spring 5 acted upon at its ends, in opposite directions through pull-rods 6 and levers 12 by forces which are proportional respectively to the pressure on the supporting springs 15. The pull-rods 6 coact with stops 8, the arrangement being such that the load Ql or Q<SP>2</SP> on the spring 15 which is at the vehicle end that happens to be the more lightly loaded, effects the fulcrum adjustment. The mechanism is similar to that described in Specification 565,517, the spring 5 being such that the deflection thereof decreases as the load on it increases, but by means of the lever 7, this deflection is multiplied to give a displacement of the fulcrum 1 such that the braking ratio increases with the load. By the interposition of a transmission linkage having the necessary gear ratio, a spring may, however, be used, the deflection of which increases uniformly with the load. Specification 490,591 also is referred to.
